[0002] 无线现场设备网络包括具有中央控制器或网关的大量设备或节点。 [0002] The wireless field device network comprises a large number of devices or nodes central controller or gateway. 无线网络中的节点能够发送和接收信息。 Wireless network node can send and receive information. 在以普及的Bluetooth®格式为例的星形网络中,网络的范围受到主机设备的传输范围的限制。 In a popular format Case Bluetooth® star network, the range of the network is limited by the transmission range of the host device. 来自从属设备的所有通信根据主机的通信进度表通过主机发送。 All communications sent from the slave device via the host communication schedule according to the host. 通过允许从属设备为不同网络的成员,使得可以以分散网状形式通过多个网络将信息从主机转播(relay)至从属设备,可以扩展无线星形网络的范围。 By allowing the slave device as a member of different networks, making it possible to form a mesh through a plurality of dispersed network broadcast information from a host computer (relay) to the slave device, you can extend the range of wireless star network. 星形网络也可以在互连网络之间形成系谱关系;从属设备变为子网络的主机设备。 Star network pedigree relationship may be formed between the interconnection network; slave device becomes the host device subnet. 星形网络拓扑的使用在通信的发送方面带来了一定的低效率,因为可以强制信息采取到达目的节点的次优路径的主-从关系存在僵化性。 Star network topology used to bring a certain amount of inefficiency in terms of communications sent, because information can be forced to take the primary destination node of a suboptimal path - the existence of rigid sex-slave relationship.

[0003] 网状网络是更灵活的网络架构,其在工业应用中正变得普遍。 [0003] The mesh network is more flexible network architecture, which became popular in industrial applications Chiang Kai-shek. 网状网络包括大量节点和控制器或网关,但通过允许同一网络内的邻近节点彼此直接通信、避免至控制器的通信的不必要的发送而避免了星形网络拓扑的多种限制。 Mesh network includes a large number of nodes and a controller or gateway, but by allowing the neighboring nodes on the same network to communicate directly with each other, to avoid unnecessary communication is sent to the controller to avoid a variety of restrictions star network topology. 每个节被分配有多个通信路径,这些通信路径是互换的以补偿瓶颈和链接故障。 Each node is assigned with a plurality of communication paths, the communication paths which are interchangeable to compensate for link failures and bottlenecks. 通过允许邻近节点形成直接到达目标节点的通信转播,并且通过在故障或瓶颈周围发送,网络响应时间得以改善,同时通过最小化转播信息所需要的传输次数而最小化网络功率使用。 By allowing the neighboring nodes form a communication relay directly to the target node, and by the failure or bottlenecks around the transmission network response time can be improved, while minimizing the number of transmissions broadcast by the information they need and minimize network power usage. 利用多个通信路径提供了路径多样性,这改善了网络可靠性。 Using a plurality of communication paths provides a path diversity, which improves network reliability. 网状网络也可以通过共用节点而彼此通信。 Mesh networks can also communicate with each other through a common node. 当存在冲突时利用算法确定网络之间的优先权,这些共用节点可以保持它作为其中的一部分的每个网络的通信进度表。 Algorithm to determine the priority between the network when there is a conflict, these common node can keep it as a communication schedule in which each part of the network.

[0004] 无线网络在无线网络不或不能彼此通信时是独立的。 [0004] The wireless network is not or can not be independent when communicating with each other in a wireless network. 对通信的屏障可以归于物理障碍物,如到自然障碍物(如山或树)或人造障碍物(如混凝土结构)的长距离,或网络固有的逻辑问题,如网络协议的差异。 A barrier to communication can be attributed to physical barriers, such as the natural obstacles (such as a mountain or a tree) or man-made obstacles (such as concrete structures) long distance, or network problems inherent logic, differences such as network protocols. 网络之间的通信的缺失是低效率的,并且可能是危险的。 Lack of communication between networks is inefficient and can be dangerous. 当控制系统不能监测位于不同的独立网络中的子系统时,中央定位的控制系统的效用被明显地降低。 When the control system can not monitor located in different independent network subsystems, utility centrally located control system is significantly reduced. 链接不同的独立网络的挑战在于,解决方案必须灵活、可靠和有效,同时不贵。 Challenges link different independent networks that solutions must be flexible, reliable and effective, but not expensive. 如采用由内联网或由单独的无线中枢链路(如,Wi-Fi)连接的网关、或无线电转发器、或家庭铺设网络电缆互连独立的无线网络的常见方法要求大的费用用于昂贵的配线和设备的安装。 Such as the common method of using the intranet or by a separate wireless backbone link (eg, Wi-Fi) connected to a gateway, or radio repeaters, or home laying network cable interconnection independent of the wireless network requires a large cost for expensive installation of wiring and equipment. 这些机制的其它问题在于,它们通常需要在无线现场设备网络服务的多个区域中不容易获得或不实际的外部功率源。 Other problems of these mechanisms is that they usually require a plurality of network service area of the wireless field devices are not readily available or practical external power source.

[0005] 术语“现场设备”涉及执行控制或过程监测系统或工厂监测系统中的功能的任何现场安装式设备,包括用在工业装置、过程或过程设备的测量、控制和监测中的所有设备,包括工厂环境、健康和安全设备。 [0005] The term "field device" refers to the implementation of any field-mounted device control or process monitoring system or facility monitoring system functions, including use in industrial equipment, process or equipment for measurement, control and monitoring of all devices, including the factory environment, health and safety equipment. 现场设备通常包括传感器或致动器或二者,并且可以进行控制或警报功能。 Field devices typically include a sensor or actuator, or both caused by, and can be controlled or alarm function. 在被设计用于基于传感器/致动器的应用的无线网络系统中,在不带来更大的安装费用的情况下,网络中的多个设备必须是本地供电的,因为电力设施,如120VAC设施或供电数据总线,不位于附近,或不允许进入仪器、传感器和致动器以及安全监测器或人接口装置必须位于其中的危险位置。 In the wireless network system is designed for based on the sensor / actuator application, at no greater cost of installation, the network of multiple devices must be powered locally, because electric power facilities, such as 120VAC facility or supply data bus, not near, or not allowed to enter instruments, sensors and actuators, and security monitors or human interface device must be located in one of the hazardous location. “本地供电”是指由本地功率源,如独立电化学源(如,长寿命电池或燃料电池)或由低功率能量提取型功率源(如,振动、日光、或热电)供电。 "Local Power" refers to a local power source, such as a separate electrochemical source (e.g., long-life battery or a fuel cell) or low power energy scavenging power source type (e.g., vibration, sunlight, or thermoelectric) power. 本地功率源的共有特征是它们存储的(如在长寿命电池情况中)或产生的(如在太阳能电池板的情况中)有限的能量容量或有限的功率容量。 There are features local power source is (as in the case of long-life battery) or produced (as in the case of solar panels in) finite energy capacity or limited power capacity of their storage. 通常,对低安装成本的经济需求推动了对作为无线现场设备网络的一部分的通信的电池供电设备的需求。 Typically, low installation cost economic demand driving the need for a wireless field device networks of battery-powered device communication part of. 有限的功率源(如不能再充电的原电池)的有效利用对有效地运行无线现场设备至关重要。 Effective use of limited power source (such as a primary battery can not be recharged) of wireless field devices is essential for effective operation. 期望电池持续大于五年时间,并且优选地持续与产品寿命一样长的时间。 Expected battery lasts more than five years, and preferably continued as long as the product life time.

[0006] 为了节省功率,一些无线网络协议通过仅仅开启它们自己的转发器有限的时间量来接听信息,限制任何节点或设备在任何时间周期期间可以处理的通信量。 [0006] In order to save power, some wireless networking protocol only open their own transponder limited amount of time to receive the information, to limit traffic any node or device during any period of time that can be processed. 因此,为了降低平均功率,协议可以允许在收发器开启(ON)和关闭(OFF)状态之间工作循环。 Therefore, in order to reduce the average power, the protocol may allow the transceiver to open (ON) and off duty cycle between (OFF) state. 一些无线网络协议可以使用全局工作循环来节省功率,使得整个网络同时开启和关闭。 Some wireless network protocol can use the global duty cycle to save power, making the entire network simultaneously on and off. 其它协议(如,基于TDMA的协议)可以使用局部工作循环,其中仅链接在一起的通信节点对被排定时间,从而在预定时间以同步方式开启和关闭。 Other protocols (eg, TDMA-based protocol) can use a local duty cycle, which links together only by the scheduled time of communication nodes, thereby opening and closing in a synchronized manner at a predetermined time. 典型地,通过为该节点对及时指定具体通信时隙、将由收发器使用的RF频道、在该时刻谁将接收和谁将发送,预先确定链路(如,如具有信道跳转协议(如无线H ART® )的TDMA)。 Typically, by this node to specify a specific communication slots in time, by the use of RF transceiver channels, who will receive and who will send at this time, a predetermined link (eg, such as having a channel hopping protocol (such as wireless H ART®) of TDMA).

[0007] 无线现场设备网络用来控制和监测不同的过程和环境。 [0007] wireless field device networks used to control and monitor the different processes and environments. 例如,无线现场设备网络可以用在油田中。 For example, the wireless field device networks can be used in oil fields. 油田包括在分散在大量区域范围内的钻井平台上对中的大量离散位置。 Oil is included in the dispersed within a large number of regional drilling platform for the large number of discrete positions. 这些隔离的本地区域之间的通信对于油田的整体管理是必要的。 Communication between these isolated local area for the overall management of oil is necessary. 钻井平台处的无线现场设备网络监测和控制所有事情,从流量和流体温度到阀的状态和位置以及潜在泄漏。 Wireless field devices at a drilling platform network monitoring and control everything from the flow and temperature of the fluid to the valve's status and location of potential leaks. 所产生的数据通过网络转播至控制器,控制器分析数据并且精确控制机制,以管理生产或防止故障。 The data generated by the broadcast network to the controller, the controller analyzes the data and precise control mechanism to manage the production or prevent malfunction. 从每个隔离的钻井平台到中央监测站的本垒打电缆可能不切实际地昂贵,因此通常采用无线管理和控制采集系统(SCADA :ffireless Supervisory and Control DataAcquisition system)来将钻井平台连接在一起成星形网络。 May unrealistically expensive isolated from each rig to a central monitoring station homer cable, it is often the use of wireless management and control acquisition systems (SCADA: ffireless Supervisory and Control DataAcquisition system) to be connected together in a drilling platform star network. 然而,SCADA系统的安装昂贵,并且通常需要昂贵的、带有给它们供电的备用电池的太阳能电池板。 However, the installation of SCADA systems are expensive, and often require expensive solar panels with battery backup power supply to them of. 油田环境对于无线网状网络可靠地运行来说可能极其困难。 Oilfield environment can be extremely difficult for a wireless mesh network for reliable operation. 钻井平台之间的距离通常大于无线现场设备的标准范围,并且通常存在对无线通信的物理障碍,如土台、罐、处理设备、摇杆/杆式泵和棚屋。 The distance between the drilling platform is generally greater than the standard range of wireless field devices, and usually exist on the physical barrier of wireless communications, such as soil units, tanks, processing equipment, rocker / rod pump and shacks. 网络之间的无线链路通常被诸如树和矮树丛之类的自然织物阻挡。 Wireless links between networks are usually blocked natural fabrics such as trees and bushes and the like. 树以约0. 35dB/m吸收 Tree to about 0. 35dB / m absorption

2. 4GHz频谱无线电发射,快速地消耗用在无线网络中的低供电无线电设备的链路预算。 2. 4GHz spectrum radio transmission, quickly consumed by a wireless network link budget low-powered radio. RF信号强度通常不够使用低水平和低供电无线的现场设备覆盖钻井平台之间的距离和克服被要求与其它无线现场设备网络通信的障碍。 RF signal strength is usually enough to use low-level and low-powered wireless field devices to cover distances between drilling platforms and other obstacles to overcome were asked to wireless field device networks communications. 这些钻井平台位置通常遥远,限制了对便利的电力源的迅速接近。 These rigs position generally distant, rapidly approaching the limits of the power source for the convenience. 这限制了可以安装的无线收发器的功率:在不存在外部电力供给的情况下,功率更大的收发器将快速地和迅速地吸取存储的能量,并且推高更换和维护成本,同时引起网络内部连接的频繁中断。 This limits the wireless transceiver can be installed power: in the absence of an external power supply, the power larger transceiver quickly and rapidly absorb energy storage, and push the replacement and maintenance costs, while causing network interconnected frequent interruptions.

[0008] 用于互连分散式独立网络的一种方法是在每个网络中安装网关或基站设备,并通过硬连线中枢链路或通过单独的无线中枢链路(如,Wi-Fi或独占点对点RF网络)链接每个网络。 [0008] A method for interconnecting separate networks for decentralized gateway or base station equipment is installed in each network, and hard-wired backbone link or via a separate wireless backbone link (eg, Wi-Fi or Exclusive peer RF network) links to each network. 这些设备存在两个主要不足:它们昂贵,并且它们是能量密集设备。 There are two main problems of these devices: they are expensive, and they are energy-intensive equipment. 远程位置可能没有足够的功率源可用于在不会频繁地维修的情况下使网关或基站长时间运行。 Remote locations may not have enough power source can be used in the case of frequent repairs will not make gateway or base station for a long time to run. 还存在与网关或基站相关联的附加成本,网关或基站通常昂贵并且需要大的功率源。 There is associated with the gateway or the base station of the additional cost, the gateway or base station usually expensive and requires a large power source. 将电缆铺设在在大的区域中分散的整个网络中是困难的,并且非常昂贵。 The cable is laid in a large area dispersed throughout the network it is difficult and very expensive.

[0009] 为了避免安装单独的通信中枢链路的困难,网络系统可以采用无线转发器来增加范围或克服障碍。 [0009] In order to avoid difficult installation separate communication backbone links, the network system may use a wireless repeater to increase the range or overcome obstacles. 转发器为大功率设备,其通过以更高的功率发送接收到的低功率信号使得信号将克服障碍并且远处的网络可以检测到它而运行。 Repeater equipment for high-power, by which a higher power transmission and reception to the low-power signal such that the signal to overcome the obstacles and the distance can be detected by the network and runs it. 这种转发器需要外部功率源来提供必要的放大。 This transponder requires an external power source to provide the necessary amplification. 远程位置可能不具有可用的足够功率源来使转发器运行。 The remote location may not have enough power sources are available to make the transponder operation.

[0010] 在其中物理空间限制是因素的应用中,克服两个网络之间的障碍的一种解决方案是采用具有两个天线的无线电收发器。 [0010] In applications where physical space limitations are factors in overcoming the obstacles between the two networks, one solution is to use a radio transceiver with two antennas. 通过将单独的天线放置在将互连的每个区域中,单个无线电收发器可以在两个区域中发送和接收信号。 By separate antenna placed in each of the interconnected region, a single radio transceiver may transmit and receive signals in the two regions. 外部RF电缆通过供电或无源RF分路器将两个天线中的每一个连接至无线电设备。 External RF cable via power supply or passive RF splitter two antennas each connected to the radio. 外部RF电缆和RF分路器的使用造成了对所使用的电缆的长度的严重限制。 External RF cable and RF splitter caused by the severe restrictions on the length of cable used. 例如,LMR-400低损耗RF电缆将在2. 4GHz处引起约 For example, LMR-400 low loss RF cable will cause approximately 2. 4GHz at

O. 22dB/米的信号损失,并且无源RF分路器在每个输出端处将可用RF信号强度降低一半。 O. 22dB / signal loss meter, and passive RF splitter will reduce the available RF signal strength at the output of each half. 实际上,这种解决方案仅可以互连两个网络,并且这些网络在信号损失使得设备无用之前必须彼此非常靠近。 In fact, this solution can only interconnect two networks, and these networks must be such that the signal loss in very close to each other before the device useless. 用RF开关替代RF分路器并在两个天线之间切换RF信号恢复一些损失的信号中,但是无线设备增加了相当大的复杂性,并且仍然留下与额外的RF天线电缆相关联的大的损失。 RF switch with alternative RF splitter and switch between the two antennas RF signal to recover some lost signals, but the wireless device adds considerable complexity, and still left with additional RF antenna cable associated with large loss.

[0093] 根据一个实施例,本地功率源239包括独立电化学源(如,长寿命电池或燃料电池)和低功率能量提取型功率源(如,振动、日光或热电)中的至少一种。 [0093] According to energy extraction and low-power mode power source to one embodiment, a local power source 239 including independent electrochemical source (such as long-life batteries or fuel cells) to implement at least one (eg, vibration, sunlight or thermoelectric) in. 如图所示,本地功率源239集成到它所连接的无线设备中。 As shown, the local power source 239 integrated into the wireless device it is connected. 可替换地,这种本地功率源是物理地分离的,但被电连接以提供电子至所连接的无线设备。 Alternatively, such a local power source is physically separated from, but electrically connected to provide an electronic connection to the wireless device.

[0094] 在操作中,用于网络212b中的节点的信息被转播通过网络212a,直达信息到达无线设备234a。 [0094] In operation, for the information network 212b of the node it is broadcast over the network 212a, direct access to the information reaches the wireless device 234a. 收发器246通过天线248接收信息并将信息传递至数据路由器250。 Transceiver 246 via antenna 248 receives information and passes the information to the data router 250. 数据路由器250检查该信息的地址字段并格式化该信息用于传输到网络212b中。 Data router 250 checks the address field of the information and format the information for transmission to the network 212b. 数据路由器250将格式化的信息发送至收发器240。 Data router 250 sends the formatted information to the transceiver 240. 收发器240则经由有线链路232将信息传输至天线242并将该信息广播到网络212b中以转播至目的节点。 Transceiver 240 via a wired link 232 to transmit information to the antenna 242 and 212b of the information broadcast to the network to broadcast to the destination node. 返回信息沿着反向路径返回。 Return information back along the reverse path. 数据路由器250将从收发器240或246接收到的信息重新格式化为适合由另一个收发器246或240广播的格式,以允许该桥接装置桥接不同的网络协议中的屏障。 Data router 250 received from the transceiver 240 or 246 as appropriate information reformatted by another transceiver 246 or 240 broadcasting format, to allow the bridge means bridging different network protocols barrier. 在功能上,两个单独的网络212a和212b变为统一无线现场设备网状网络210。 Functionally, the two separate networks 212a and 212b into a unified wireless mesh network 210 field devices.

[0097] 如上所述,图7A-7B中示出的实施例采用用于有线链路的RF电缆。 [0097] As described above, Figures 7A-7B shown embodiment employs RF cable for wired links. RF电缆引起信号损耗,这限制了有线链路越过无线通信的屏障可以跨越的距离。 RF signal loss caused by the cable, which limits a wired link over the wireless communication barrier can span distances. 然而,与现有技术相反,本发明不采用将会增加成本的复杂的RF开关或将严重地限制有线链路可以跨越的距离的RF分路器。 However, contrary to the prior art, the present invention is not used will increase the cost of the complex RF switch or a wired link may severely limit the distance spanned by an RF splitter. 对于相对短的跨越,如,穿过墙壁,或对于逻辑屏障,如网络协议差异,图7A-7B的实施例会是最有效的解决方案。 For a relatively short span, such as through walls or barriers for logic, such as network protocol differences, Figure 7A-7B embodiment would be the most effective solution.

[0098] 在本发明的所有实施例中,有线链路由所连接的本地供电无线设备单独地供电。 [0098] In all embodiments of the present invention, the wired links solely powered by the local power wireless devices are connected. 这与其中总线本身由外部源供电并且可以提供电力至现场设备的现有现场设备网络总线相反。 This is where the bus itself is powered by an external source and can provide power to the opposite field devices existing field equipment network bus. 本发明理想地适合其中这种外部源不容易获得的位置。 The present invention is ideally suited where such an external source is not readily available location. 为了保持低功率,有线链路的数据率应当相对高,至少具有与用来连接的无线协议的数据率一样的量级。 In order to maintain a low-power, data rate cable links should be relatively high, at least have a data rate of wireless protocols used to connect the same order of magnitude. 例如,采用无线HARTk,无线数据率为250Kbits/秒,因此有线链路数据率应当近似位于相同的速度范围内,例如,大于IOOKbits/秒。 For example, wireless HARTk, wireless data rate 250Kbits / sec, thus wired link data rate should be approximately located in the same speed range, e.g., greater than IOOKbits / sec. 因为有线链路的功率效率比无线链路的功率效率好很多,有线链路数据率可以稍微低于无线数据率,而不牺牲太多的可用本地功率,如电池寿命或能量采集输出。 Because power efficiency much better than a wired link power efficiency of the radio link, a wired link data rate may be slightly lower than the data rate of the radio, without sacrificing too much of the available local power, such as battery life or energy harvesting output. 快速的数据率允许本发明的本地供电无线设备在开启(在它们快速通信时)和关闭之间工作循环,最小化开启时间和降低平均功率使用。 Fast data rate allows the local power supply of the present invention a wireless device in the open (when they fast communication) between the closed and duty cycle, to minimize average on-time and reduce power usage.

[0099] 以其它方式互连独立的无线现场设备网络以形成统一现场设备网络通过使得单个网络管理器能够管理和控制组合的网络并且通过允许无线网络内的节点直接地询问位于分开的无线现场设备网络中的远程传感器和其它节点而增加效率。 [0099] In other interconnect independent wireless field device networks to form a unified field device networks by enabling a single network manager to manage and control a combined network and directly asked on separate wireless field devices by allowing nodes within a wireless network network remote sensors and other nodes and increase efficiency. 这增加了整个统一现场设备网络中立即可获得的信息,允许对变化事件的更精确和及时地响应。 This increases the overall unified field device network information immediately available, allowing changes to events more accurately and timely response. 本发明提供具有比用于在障碍物附近路由网络间通信的当前方法低的成本、损失和功率的解决方案。 The present invention provides a solution for more than an obstacle in the vicinity of the route network between the current low cost method of communication, and power loss. 代替包括具有链接多个天线的RF分路器或RF开关和外部RF电缆的单个无线电设备的当前方法,采用有线数据链路明显地降低了信号损耗。 Instead of including a link to a plurality of antennas RF splitter or external RF switches and RF cables single radio device current method using a wired data link significantly reduces the signal loss. 通过降低RF损失,无线设备的功率要求降低,使得本地供电设备是可行的。 By reducing RF losses, to lower power wireless devices, such that the local power supply device is feasible. 本发明容易安装。 The present invention is easy to install. 有线链路仅需要足够长以跨越障碍物,避免因特网中枢链路或本地铺设链路所需要的昂贵的长配线铺设。 Wired link need only be long enough to span the expensive long line of obstacles, avoid Internet backbone link or links required local lay laying. 由于无线设备容易被编程以使用任何标准网络协议,因此与现有网络中的当前硬件存在现成可用的互操作性。 Since the wireless device is programmed to easily use any standard network protocols, so there is readily available interoperability with existing networks in the current hardware. 采用多个无线设备还允许本发明连接使用不同网络协议的网络,使得更容易管理、升级和扩展现有现场设备网络。 Use multiple wireless devices also allow the use of the present invention is connected to a different network protocol network, it makes it easier to manage, upgrade and expand the existing network of field devices.
