对于数字综合环形网络的现有技术曾在一些文章中予以描述,例如,Ito等人在“C&C-NET Loop 6830 Univer-sal Link system:NEC Technical Report Vol.36.№7/1983:PP32-38,”技术报告中所进行的描述。 Has be described in some prior art articles for digital integrated ring network, e.g., Ito et al., "C & amp; C-NET Loop 6830 Univer-sal Link system: NEC Technical Report Vol.36.№7 / 1983: PP32 -38, "technical report carried description. 在该技术报告中公开的传输系统,电路交换功能是由多个时分的时隙来完成的。 Transmission system disclosed in the technical report, the circuit exchange function is time-divided by a plurality of time slots to complete. 当要对信号如数字化的活动数据这样大量的通信量估为传输数据进行处理并且网络的同时的存贮量又受到严格的限制时,则该系统需要大量的上述时隙。 When the signal to a large number of traffic such as digitized data estimated for the transmission activity data is processed and the amount of network simultaneous storage and severely restricted, the system requires a large amount of the above-mentioned time slots. 对于环形网络拓朴,存在一种利用星形网络的系统。 For ring network topology, there is a system utilizing a star network. 其中,相应的各中继线都连接在一起。 Wherein each of the respective trunks are connected together. 例如在“A Local Communications Network Based on Inter-conne-cted Token-Access Rings:“A Tutorial:IBM J.RES DEVELOP Vol.27,NO.5,1983:C.Strole PP.481to496.中所描述的。 For example, in "A Local Communications Network Based on Inter-conne-cted Token-Access Rings:" A Tutorial: IBM J.RES DEVELOP Vol.27, NO.5,1983:. C.Strole PP.481to496 described. 然而,这个系统的目的在于改善它的可靠性,并且,称之为“线路集中器”的电路转换装置,仅公开了其电路结构和旁路不正常的工作站,这样的操作丝毫不能改善其传输的性能。 However, the purpose of this system is to improve its reliability, and, referred to as "line concentrator" circuit switching means, only discloses a bypass circuit configuration and abnormal workstation, such an operation does not improve its transmission performance.

本发明的目的是提供一个具有可变站次序的环路传输系统。 Object of the present invention is to provide a loop transmission system having a variable station order. 该系统能够在一种环形网络中复用和存贮对于高速传送大量的信号如活动的图象一类的数据所必需的通信量。 The system is capable of multiplexing a ring network and storing traffic signal for high speed transmission of large amounts of data such as an image of a class of activity necessary.

根据本发明,环形网络的各中继线都集中在同一位置。 According to the present invention, each trunk ring network are concentrated in one place. 在这一位置上,各传输站的连接次序根据传输的需要而变化。 In this position, the connection order of the transmission stations varies according to the transmission needs. 且注意,该电路交换适用于长时间存贮的数据,但必须立即恢复。 And noted that the circuit-switched data stored for long hours, but it must be restored immediately. 然而,通过该环形网络的分组交换适用于其它类型的数据,以便使在同一条传输线上复用具有不同业务特征的数据的两种交换成为可能。 However, the ring network via a packet switching applicable to other types of data, so that the two multiplexed on the same transmission line having different traffic characteristics of the data exchange possible. 这种环形网络的特征是:如果接收数据的接收站位于靠近发送上述数据的发送站下游,该环形网络可以在同一时间周期,同时对多个站进行信息的传输。 Characteristics of such a ring network is: if the data receiving station is located near to the transmitting station transmits the data to the downstream, the ring network can be at the same time period, a plurality of stations simultaneously transmitting information.

现参照图1,来描述本发明的一个实施例,图1表示了应用本发明的环形网络的整体结构的例子。 Referring now to Figure 1, will be described an embodiment of the present invention, FIG. 1 shows an example of the overall configuration of a ring network of the present invention is applied. 如图所示,标号11到18,是各种数据处理机,信号如各种计算机或终端,可以分散安装在工厂,建筑物和大学里,分别通过传输站21到24共同一个环形传输系统,在它们中间依次地传送数据,其中,每一个传输站是由发送机(T);2127,2227,2327,2427;接收机(R):它们的标号为:2111,2211,2311,2411,间隙复用控制装置(TMP):211,221,231,241,装置的适配器(ADP):131,132,133,134,141,142,143,144,151构成。 As shown, the numbers 11-18, a variety of data processing machines, a variety of signals, such as a computer or terminal can be dispersed installed in factories, buildings and universities, respectively, through the transfer station 21-24 together a ring transmission system, sequentially transferring data between them, wherein each transmission by a transmitter station (T); 2127,2227,2327,2427; a receiver (R): they are labeled: 2111,2211,2311,2411, clearance multiplexing control means (TMP): 211,221,231,241, adapter (ADP) means: 131,132,133,134,141,142,143,144,151 constituted. 各传输站通过串行传输线3连成一个环路,并且,这些中继线是暂时集中在叫做“流量变换器”的集中器4上形成一个星形网络。 Each transfer station through the serial transmission line 3 together into a loop, and these trunks are temporarily focused on the formation of a star network is called "flow converter" concentrator 4. 这里的流量变换器是由发送机451到454;接收机411到414;转换装置41和转换控制装置42组成。 The flow rate converter here is by the transmitter 451 to 454; receiver 411-414; conversion means 41 and switching control means 42 components. 如图所示。 As shown in FIG. 至于怎样对连接次序进行判断,是用传输站21的适配器装置(ADP)151来实现的。 As for how to judge the connection order, with the transmission station adapter device (ADP) 21 151 to achieve. 并且,它的指令被输送到转换装置(CTL)42。 And its instruction is delivered to the converting means (CTL) 42. 所说的连接次序是指传输站21,22,23和24的次序,如转换控制装置41中的虚线所表示的那样。 The order of connection means of said transmitter stations 21, 22 and 24 of the order, as in the switching control means 41 as indicated by a broken line. 图中所示的例子中,传输站的数目是4,并且,分别与两个数据信息处理机连接。 The example shown in the figure, the number of transmission stations is 4, and respectively connected with two data processors. 然而,尽管如此,本发明的目的不是限制站和信息处理机的数量。 Despite this, however, is not the object of the present invention to limit the number of stations and an information processor. 这些相应的部件将一步一步地阐述如下。 The corresponding parts will step by step described below.

根据其传输业务的特点将与传输站连接在一起的数据处理器分为下面两种类型:(1)类型1:其中,经过长时间的存贮数据必须是立即恢复的。 According to the characteristics of its transmission business will stand together in connection with the transmission of the data processor is divided into the following two types: (1) Type 1: where, after a long period of storage of data must be immediately restored.

(2)类型2:其中,不要求立即恢复,这样便精确地执行短时间存贮的数据的转移。 (2) Type 2: Those that do not require immediate recovery, thus accurately execute the transfer of short-term storage of data.

在图1的结构举例中,类型1的设备是通过工业电视摄象机12,图象处理器15、彩色静止图象文件14和图象恢复终端17来举例说明的。 In the configuration of Figure 1 for example, the device type 1 is obtained by industrial TV camera 12, an image processor 15, a color still picture file 14 and the image to return the terminal 17 illustrated. 而类型2的设备是通过计算机11,13和其数据处理终端16,18举例说明的。 The device type 2 is performed by the computer 11, 13 and their data processing terminals 16, 18 illustrated. 并且,系统中表明,那些具有不同信息量特性的数据能够共用同一条传输线路。 Further, the system shows that those data having different information can share the same characteristics of the transmission line. 一般地讲,在公知的现有技术中,电路交换适用于前者类型的数据,而分组交换适用于后者类型的数据。 Generally speaking, in the known prior art, the former is suitable for the type of circuit-switched data, whereas the latter is suitable for the type of packet-switched data. 为了实现这一点,按照本发明,流量变换器4中的连接次序是受到控制的,这样,与图象处理器15相连的传输站23,恰恰位于与工业电视摄象机12相连的传输站21的下游,并且与图象恢复终端17相连的传输站24位于与信息传送器作用的图象元件14相连的传输站22。 To achieve this, according to the present invention, the connection order in the stream changer 4 is controlled, so that the image processor 15 is connected to the transmission station 23, precisely located with industrial television camera 12 is connected to the transmission station 21 downstream, and a terminal 17 connected with the image restoration transmission station information transmitter 24 is located and the role of the image element 14 is connected to a transmission station 22.

现在,参照图1的描述导致这样一种情况在系统中流量变换器是一个放射形的网络形状,而根据本发明的传输系统并不仅限于此。 Now, described with reference to FIG. 1 lead to a situation in the system flow rate converter is a radial shape of the network, while the transmission system according to the invention is not limited thereto. 更为具体地讲,图2表示出了由许多流量变换器构成的一个单独的星形网络构形图。 More specifically, Figure 2 shows a single star network configuration diagram constituted by a number of the flow rate converter. 附带实例为简化说明,各个传输站之外的各种部件,各流量变换器和各传输线在图中没有示出。 Examples incidental simplify the explanation of the various components other than the respective transmission stations, each of the flow rate converter and each transmission line is not shown in FIG. 当使用的系统规模很大,这时系统就需要拥有比图1的系统拥有更加庞大的传输站和在传输站与传输站之间具有更加长的距离。 When the large-scale use of the system, then the system would need to have a transmission station has a much larger than the system of Figure 1 and has a much longer distance between the transmitting station and the transmission stations. 这时本发明的结构具有很大的优越性。 In this case the structure of the present invention has great advantages. 使用这种形式,可以缩短传输线路的尺度和限制同流量控制器连接在一起的传输站的数量。 Using this form, you can shorten the scale and restrict flow controller connected together with the number of stations transmitting transmission lines. 图3表示了一种具有由网络结构构成的环形网络的例子。 Figure 3 shows an example of a network having a ring structure constituted by the network. 这种网络结构能更好的抵制传输阻碍。 This network architecture can better resist the transmission obstacles. 因为,传输线的端口连接着流量变换器。 Because the port is connected with the transmission line flow rate converter. 例如,在本例中,在SC1和SC4之间能构成传输线的一部份,以便形成冗余的备用传输线。 For example, in this embodiment, between the SC1 and SC4 can form part of the transmission line, to form a redundant backup transmission line.

为了说明根据本发明的传输系统各个部分的运行,在图4中表示传输时间图的一个例子。 To illustrate the operation of each part according to the transmission system of the present invention, showing an example of the transmission time chart in Figure 4. 此外,这一例子将对应着以下所述信息量同时发生在图1所示的系统结构中的状况。 In addition, this example will be described below corresponds to the amount of information in the system configuration status simultaneously shown in the figure.

在本图中,前面提到的通信量(3)是由使用时隙TS1来处理的;通信量(4)由时隙TS2处理;通信量(1)由时隙(TS4和TS5)处理;通信量(2)由间限TS4处理。 In this figure, the aforementioned traffic (3) is processed by using the time slot TS1; traffic (4) processed by the slot TS2; traffic (1) by the slot (TS4 and TS5) processing; traffic (2) treatment by the Inter-limit TS4. 可以注意到在一帧中,一些时隙被用于传输类型1的数据的一些站全部使用。 It may be noted in a frame, time slots are used for some type of a data transmission stations all use.

发送数据的获得从传输线3送到接受器(STR)2111里,再经过定时变换器(TC)2113,经过系统环路控制器(FC)2114、时隙首部控制器(THC)2115、及多路复用器(MPX)2116和一发射器(STT)2127重新发送出去给传输线3。 Obtaining transmission data from the transmission line 3 to the receiver (STR) 2111 years, and then through a timing converter (TC) 2113, through the system loop controller (FC) 2114, the time slot header controller (THC) 2115, and multi- multiplexer (MPX) 2116 and a transmitter (STT) 2127 re-transmitted to the transmission line 3. 下面这个也是同步的,即输出系统回路控制器(FC)2114也将数据送到了检波器(DEM)2118,因此同时也通过串/并联变换器(S/P)2119传递。 The following is synchronous, i.e., the output of the system loop controller (FC) 2114 is also supplied to the data detector (DEM) 2118, and therefore also through the series / parallel converter (S / P) 2119 transfer. 在数据确定的情况下送到本站,更多地通过缓冲记数器(BUF)2120、关连着设备的连接装置-数据总线INBUS和适配器|3|,|4|和|5|送到关连机构11,12和4。 In the case of data sent to the site determined more by the buffer counter (BUF) 2120, off attached devices connected device - data bus INBUS and adapters | 3 |, | 4 | and | 5 | connected to mechanisms 11, 12 and 4. 相反地,数据的发送从关连机构11和12发送出去通过适配器|3|和|4|,关连着设备的连接装置-数据总线OUTBUS、缓冲记数器(BUF)2124、并/串联变换器(P/S)2125、调制器(MOD)2126、多路复用器(MPX)2116和发送器(STT)2127送给传输线3。 Conversely, sending data from related institutions 11 and 12 sent through an adapter | 3 | and | 4 |, off connecting device attached devices - data bus OUTBUS, buffer counter (BUF) 2124, and / serial converter ( P / S) 2125, the modulator (MOD) 2126, the multiplexer (MPX) 2116, and a transmitter (STT) 2127 to the transmission line 3. 表示目前传输站的控制的更详细的细节描述结合参阅工艺流程图图表将展示在图8到图11。 Further details said the current control described in connection with the transmission station See flow chart diagram will show in Figures 8 through 11. 图8展示了开始时同步系统工艺流程图的建立,在这种情况下,象传输控制站一样操纵目前的传输站。 Figure 8 shows the beginning of the establishment of the synchronization process flow diagram of the system, in this case, as the transmission control station currently operated as a transmission station. 此外,还将说明操纵着的系统回路控制器2174和定时变换器2113。 In addition, the system will be explained manipulated timing converter loop controller 2174 and 2113. 首先,多路复用器2116设置在B面,启动发送数据模型的操纵,进一步证实本系统是一个封闭系统的回路。 First of all, the multiplexer 2116 is provided B side, starts sending data manipulation model, further confirmed the system is a closed loop system. 靠使用接收时钟脉冲如同输入计时首先要计数,靠使用发送时钟脉冲如同输出计时首先要计数来建立下一个定时转换的体会。 By using the receiver clock as the input clock to count first, by using a transmit clock pulse output timing as the first to experience the next count to create a timed conversion. 随后预先存储的二进制数码数据最后完成预定的时间周期。 Then stored binary digital data to finalize a predetermined time period. 在这个相匹配的二进制数码的存储器里,各种不同的状态和时钟脉冲振幅随着任意一个数据的发送和接收进行了减震。 In this match the binary digital memory, the various state and clock pulse amplitude as the send and receive data were arbitrary damping. 当封闭环路中该假定的数据模型要改变是合理的时,调制器(MOD)2126接收到后并发送出去同步系统的同步系统字符。 When the closed loop model assumes that the data is reasonable to change the time, and after sending a modulator (MOD) receiving the synchronization system 2126 out character synchronization system. 这以后,同时将模型数据发送出去,系统环路控制器(FC)2114接收到后启动它的操纵。 After this, the data model will be sent out at the same time, the system loop controller (FC) 2114 received after starting its operation. 在得到响应频率中的指令时,系统环路控制器(FC)2114接着启动存储器接收数据,当封闭环路系统的同步系统字符SYN已检测到时,接着开始提取那些有秩序地专门存储的数据一直进行下去,直到系统的终端检测到为止。 When the frequency obtained in response to an instruction, the system loop controller (FC) 2114 then starts the memory reception data, when the character synchronization system SYN closed-loop system has been detected, then start to extract data that is stored in an orderly manner special always continue until the end system detected. 由于这个结果,上述的抑制效应会起到补偿作用。 Because of this result, the inhibitory effect of these will play a role in compensation. 一个环路的抑制效应建立以后,多路复用器(MPX)2116作为转换开关安置在B面,开始进行从系统环路控制器2114读出来的每一个数据的转发。 After the establishment of the inhibitory effect of a loop, the multiplexer (MPX) 2116 as a switch disposed in the B side, the system starts a loop controller 2114 is read out from each of the data forwarding. 在这个时间,系统里首部的每一个时间间隙是预置零的,以便每个传输站可以完成它的发送操纵。 At this time, the system every time slot header is preset to zero, so that each transmission station can perform its sending operation. 当目前的传输为自身的发送操纵时,当目前的传输站象一个正常情况下的传输站时,预置的初始值可以完全地等待建立一个同步性的二进制数码的同步性系统。 When the current transmission to send their manipulation, transfer station when the current transfer station as a normal case, the initial value of the preset can wait for the establishment of a fully synchronous binary synchronous digital system. 当多路复用器2116是放在A面的时候,没有任何存储数据在系统环路控制器(FC)里。 When the multiplexer 2116 is on the A side, when there is no data stored in the system loop controller (FC) inside.

图9不仅展示了每个传输站的操纵控制和接收的工艺流程图,但也说明了操纵接收数据的转换控制器(RTC)2121。 Figure 9 shows not only the steering control and the process flow diagram of the receiving station of each transmission, but it also shows the manipulation of the received data into the controller (RTC) 2121. 接收的数据随后建立一个同步系统是通过检波器(DEM)2118的引导和并/串联变换器(P/S)2119送到接收传递数据的控制器(RTC)2121。 The received data followed by the establishment of a synchronous system is to guide and parallel / serial converter (P / S) 2119 sent to the receiving data transfer controller (RTC) 2121 by the detector (DEM) 2118's. 这种接收传递数据的控制器(RTC)2121并且有存储特定的寻址特性DA和数据展宽特性LNG是响应频率送的信号由时间间隙控制器(TSC)2122里得来的,表示这时隙首部数据是存在的。 This receives data transfer controller (RTC) 2121 and has addressed the specific characteristics of the storage and data DA broadening the frequency response characteristics of LNG is a signal sent by the time gap controller (TSC) 2122 come in, said that this time slot header data is present. 当特性的寻址到自身站的情况下,相应的适配器从缓冲记数器(BUF)2120的存储信息中取得指令。 When the characteristics of the case addressed to the self station, the corresponding adapter acquisition instruction from the buffer counter (BUF) 2120 for storing information in the. 许多的信息组的传递依赖于数据展宽性的存储不断提高。 Many of transitive dependencies information group broadening of the data storage continues to increase.

图10展示了一组转换器型式的数据发送的工艺流程图。 Figure 10 shows a set of converter type data transmission process flow diagram. 结合参考图10,其后再看图11。 In conjunction with reference to Figure 10, Figure 11 and then. 细节描述将依据操纵控制的发送数据转换控制器(STC)2123和时隙首部控制器(THC)2115的主要部分为基点。 Details of a main portion of a base point in accordance with the steering control transmission data conversion controller (STC) 2123 and the time slot header controller (THC) 2115 of. 例如:连接设备11和RQ有一个输出请求,进行的一组转换是通过适配器(ADP)131到发送数据交换电路(STC)2123。 For example: the connected device has an output 11 and RQ request, a group of conversion is via adapter (ADP) 131 to transmit data exchange circuit (STC) 2123. 这里,设备所需要求是数据的来由是明确的和是有情报根据的,这一信息的报告是送到时隙首部控制器(THC)2115。 Here, the required equipment is the reason the data requirements are clear and are based on the information, the information in this report was sent to the time slot header controller (THC) 2115. 时隙首部控制器(THC)2115的一组F/B二进制数码和在该响应频率中的时隙由时隙控制器2122送到时隙首部的检波信号器。 Time slot header controller (THC) 2115 a group of F / B binary numbers and slot in the frequency response of the detector signal slot controller 2122 to the first section of the slot. 如果F(时间间隙是任意的),须重新记录到B(无空闲的),并且把有情报根据的发送数据转换电路(STC)2123。 If F (time gap is arbitrary), to be re-recorded to B (non-free), and according to the intelligence of sending data conversion circuit (STC) 2123. 这种发送数据的转换电路(STC)2123收到了适配器(ADP)131的信息并进行数据转换。 This transmission data conversion circuit (STC) 2123 receives the adapter (ADP) 131 of the information and data conversion. 并且多路复用器(MPX)2116选择在B面,从而完成发送的操纵。 And a multiplexer (MPX) 2116 to select the B side, thereby completing manipulation transmitted. 时隙的数量被使用,在于这一时刻的读出和被时隙控制器(TSC)2112存储。 Number of time slots is used, in that the read-out of the moment and the time slot controller (TSC) 2112 stored. 当一次的发送操纵或者更多的时间间隙是想要用时,很有必要要等待下一个系统里的相同的一个时间间隙周期。 When one or more transmission manipulation desired time gap is used when it is necessary to wait for the next system in the same time a gap period. 当发送的工作完成时,该时间间隙可无空闲的二进制数码会重新记录取代任意空间码。 When the job is sent is complete, the gap can not spare the time binary digital re-recording replace any space code.

图11展示了进一步地发送数据的交换电路型式的流程图。 Figure 11 shows a flowchart of further transmission of the circuit exchange type data. 例如:由相关连的设备中的交换电路型式送出一个发送数据的请求RQ2,是通过适配器(ADP)141送到发送数据转换电路(STC)2123。 For example: the associated device sends a circuit exchange type of sending data request RQ2, is via an adapter (ADP) 141 to the transmission data converter circuit (STC) 2123. 这里,送给时隙首部控制器(THC)2115的数据,设备所做出的请求应是明确的和是有情报根据的。 Here, given the time slot header controller (THC) 2115 data request, the device should be made clear and are based on intelligence. 现时更具体一些,即当时隙被交换电路型式使用,如图4所用,它的波幅在提高的情况下为确定的。 At present, more specific, i.e., the time slots are used circuit exchange type, as shown in 4, in which the amplitude is determined to improve the situation. 在有根据的时间间隙数量的基准上,根据来自时隙控制器(TSC)2122。 There are based on the number of the reference time slot, according to the time slot from the controller (TSC) 2122. 时隙首部控制器(THC)2115校验相应的P/C二进制数码的时隙并进行分析,不管它是否已经被交换电路使用。 Time slot header controller (THC) 2115 checksum corresponding P / C binary number of time slots and analyzed, regardless of whether it has been switched circuits used. 如果二进制数码被一组交换使用,该系统就需等待时隙直到它是空闲的。 If a set of binary numbers is used to exchange, the system would need to wait until it is time slot idle. 当时隙是空闲的,它又会重新恢复到无空闲的状态。 At that time slot is idle, it will restore to no idle state. 与此同时,使用的交换电路重新记录P/C二进制数码里。 At the same time, switching circuit used to re-recording P / C binary numbers inside. 这种无空闲状态是反复地进行的,是根据该设备12的时隙要求的数目进行。 This non-idle state is repeatedly carried out, the apparatus is carried out according to the number of slots 12 required. 当所有的无空闲状态是极限时,此外,该情况还要发送给数据转换控制器(STC)2123和发送给适配器(ADP)141,它们读到一个频闪观测器的信号WSTB,此时,也正是多路复用控制器(MPX)2116放在B面。 When all of the non-idle state is the limit when, in addition, the case should be sent to the data conversion controller (STC) 2123 and sent to the adapter (ADP) 141, they read a strobe signal WSTB, at this time, It is also a multiplexer controller (MPX) 2116 on the B side. 当一次交换电路型式的数据转换产生,相同的时隙不会被另一组交换电路型式的设备使用,因为F/B时隙首部的二进制数码仍然保持是无空闲的。 When a switching circuit to generate the type of data conversion, the same time slot will not be another group of switched circuit type devices, because the F / B time slot header binary digital remains are not idle. 当这种要求交换的工作结束时,时隙首部的二进制数码从使用交换电路中重新记录,如下一组交换使用。 At the end of this work requires the exchange, the head of the slot from the use of binary digital switching circuit re-record as a group are used interchangeably. 如果一组相同的二进制数码在跟随一闭合环路的周期时暴露出来它是未恢复记录的,F/B二进制数码就会变为空闲着的,因为其它的发送要求是送流量变换器。 If a group of the same binary digital exposed in a closed loop cycle to follow when it is not restored records, F / B binary digital will become idle significant, because the other transmission requirement is to send traffic converter. 后半部的结果,即变为下述的两种匹配的方法。 Results half of that into two matching methods described below. 关系到如何发送得到的数据。 Related to how the data is sent to get. (2-2-a)这种得到的数据需通过穿越传输站的设备连接总线。 Data (2-2-a) of this need to get through the transmission station devices connected via bus. 正如图1所示。 As shown in Figure 1.

信息处理机1512主要是由一台微处理机(SCADP)1521,一台中断控制器(PIC)5122、一台高速存储传输控制器(DMAC)1523,一台计时控制器(PTM)1524及一台程序存储器(ROM)1520所组成。 Information processor 1512 mainly by a microprocessor (SCADP) 1521, an interrupt controller (PIC) 5122, a high-speed memory transfer controller (DMAC) 1523, a timing controller (PTM) 1524 and a Taiwan program memory (ROM) 1520 formed. 从时隙多路复用器装置(TMP)211中转送的转换请求在传输接口电路(SBIC)1511输入送进先进先出存储器1531,并通过高速存储传输控制器(DMAC)1523记录在存储器(RAM)1514中,直到被微信息处理机(MPU)1521识别。 From time slot multiplexer means (TMP) 211 in the transfer switching request in the transmission interface circuit (SBIC) 1511 input feed FIFO memory 1531, and through the high-speed memory transfer controller (DMAC) 1523 recorded in the memory ( RAM) 1514, and until the microprocessor (MPU) 1521 identification. 对从微信息处理机(MPU)1521获得的对转换请求的回答和中断指令及重新发送来的存储到存储器中。 Answer to the request for conversion obtained from the microprocessor (MPU) 1521 and the interrupt instruction and the re-transmitted stored in the memory. 然后通过高速存储传输控制器(DMAC)1523存储在先进先出记录器1530和传输接口电路(SBIC)1511,直到把这些指令发送给时隙多路复用器的操纵装置为止。 Then by high-speed memory transfer controller (DMAC) 1523 stored in the FIFO 1530 and the recording transmission interface circuit (SBIC) 1511, until these instructions sent to the timeslot multiplexer operating device so far. 另一方面,从微处理机(MPU)1521借助于指令接口电路1513,在转换操纵装置42和在流量转换器4中,相同的信息直接记录。 On the other hand, from the microprocessor (MPU) 1521 by means of a command interface circuit 1513, the shift control 42 and the flow converter 4, the same information directly recording apparatus.

在信号调节适配器151中改变流量转换器4的过程将参照原理图图表14有更详细地描述。 Varying the flow rate converter in the signal conditioning process 4 of the adapter 151 with reference to the schematic diagram 14 is described in more detail. 例如:假设有4个传输站和直接的连接次序是1,2,3,4,1,…等等,当信号调节适配器151在一个存储器(RAM)1525中显示时,这里,存储本站的前面的地址被指示在SOTTA和从地址指示的连接次序的几个步骤。 For example: Suppose there are four transmission stations and direct connection order is 1,2,3,4,1, ... and so on, when the signal conditioning adapter 151 displays in a memory (RAM) 1525 when, where, storage site in front of the address is indicated in the SOTTA and connections from the address indicated in the order of several steps. 现在,假设传输站1接收转换指令给传输线3。 Now, suppose that the transmission station receives a command to convert the transmission line 3. 在这时,用瞬时传输站联接指令图表SOTTA+3的下列方式里,在转换控制设备42的流量转换器4中,处理机准备指令,建立起两个缓冲记数器4211和4212。 At this time, with the instantaneous transmission station connection order charts SOTTA + 3 in the following manner, in the switching control device 42 of the stream changer 4, the preparation instruction processor, to establish two buffer counters 4211 and 4212. 在记数器4211里被储存的指令是由有存储地址RESTA的下列三个代码组成。 In 4211 counter instruction is stored in a memory address RESTA by following three code.

题目:(a)RESTA……接收站地址(3); Topic: (a) RESTA ...... station address (3);

(b)RESTA+1……接收仅是上游站地址(2);和(c)RESTA+2……接收仅是下游站地址(4)。 (B) RESTA + 1 ...... receiving only upstream station address (2); and (c) RESTA + 2 ...... receiving only downstream station address (4).

在计数器4212里被储存的指令是由有存储器地址的下列三个代码组成。 4212 is stored in the counter instruction is caused by a memory address of the following three code.

(d)SEITA……发送站地址(1); (D) SEITA ...... sending station address (1);

(e)SEITA+1……接收站地址(3);和(f)SEITA+2……发送仅是下游站地址(2)。 (E) SEITA + 1 ...... the receiving station address (3); and (f) SEITA + 2 ...... transmitting only the downstream station address (2).

这以后,瞬时传输站连接指令图表被更新。 After that, instantaneous transmission station connection instruction chart is updated. 在一台存储器地址TEMPA里紧接步骤为暂时撤回接收站地址(3),用增量,用一个代码全部存储的内容从已存储的存储器地址(SOTTA+1)发送出仅如下游站地址(2),用接收站地址(3)送已存储的存储器地址(SOTTA+2)。 In a memory address TEMPA immediately step in the receiving station to the temporary withdrawal of address (3), incremental, all the memory contents with a code from a stored memory address (SOTTA + 1) are transmitted only tour station address ( 2), with the receiving station address (3) send the stored memory address (SOTTA + 2). 于是,变为存储信息损失的地址SOTTA+1和用2记录的地址SOTTA+2。 Thus, the loss of information stored into the address SOTTA + 1 and recorded with the address SOTTA 2 + 2. 经过这些,在TEMPA内的暂时回存储信息被传送给前面已经提到的发送仅是下游站地址的存储器地址(SOTTA+1)。 After these, the information is temporarily stored in the back TEMPA is transferred to the already mentioned previously transmitted just downstream station address of the memory address (SOTTA + 1). 结果,传输站的连接次序是1,3,2,4和1,。 As a result, the transmission station connection order is 1,3,2,4 and 1 ,. 这个次序发送给显示器(DISP)150。 The order is sent to the display (DISP) 150. 因为转换控制装置42从存储器地址RESTA得到存储信息可能被传送给缓冲计数器4211,从存储器地址SEITA中得到的存储信息可能被传送给缓冲计数器4212。 Since the switching control means 42 to obtain stored information from the memory address RESTA may be transferred to the buffer register 4211, for storing information obtained from the memory address SEITA may transferred to the buffer register 4212. 图15展示了如何使传输站的连接次序用前面已提到的变换过程来引起改变。 Figure 15 shows how to make the connection with the order of transfer stations transformation process previously mentioned to cause change. 图15(a)展示了改变前的符号。 Figure 15 (a) shows the symbol before the change. 存储器地址RESTA的存储信息被传送给缓冲计数器4211和SEITA的存储信息被送给缓冲计数器4212用于记录,象图15(b)展示的那样。 Storing information memory address RESTA is transferred to the buffer register 4211 for storing information and SEITA is used for recording to the buffer register 4212, as in Fig. 15 (b) as shown. 综上所述,如果地址RESTA+1的存储信息被传送到计数器4211和4212,由图15(c)获得。 In summary, if the address information stored RESTA + 1 is transferred to a counter 4211 and 4212, from Fig. 15 (c) obtained. 此外,如果地址RESTA+2的存储信息被传送到计数器4211和4212,由最后的模式图15(d)获得。 In addition, if the address information stored RESTA + 2 is transferred to the counter 4211 and 4212, by the last pattern in Fig 15 (d) obtained.

(发明的作用)同样地当一种大数量的一高速转换运输需要和大容量的如同转输数字的生动的图象在这个系统里产生,根据目前的发明,它们可以提供用电路交换使用相同的时间间隙。 (Effect of the invention) in the same manner when a large quantity of a high-speed conversion and transportation needs as transfusion digital vivid image generation large capacity in this system, according to the present invention, they can be provided by using the same circuit-switched time slot. 其结果,这个环路传输系统的传输性能会强有力地改进。 As a result, the transmission performance of the loop transmission system will be strongly improved.
