[0001] 本发明主要涉及无线网络,并且更特别地,涉及互连由无线通信的屏障逻辑地或物理地彼此隔开的无线现场设备网络。 [0001] The present invention generally relates to wireless networks, and more particularly, to interconnect the barrier logically or physically separated from each other wireless communication wireless field device networks.

背景技术 Background technique

[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] wireless field device network comprises a large number of devices or central controller node or gateway. 无线网络中的节点能够发送和接收信息。 Wireless network node is capable of sending and receiving 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 universal Bluetooth® star network format as an example, 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 a slave device according to the host via the host communication schedule. 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 disperse the form of a mesh network by a plurality of information from the host relay (relay) to 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 can also be formed pedigree relationship between the interconnection network; a 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 sending communications, because the information can be forced to take the primary destination node suboptimal path - from the presence of rigid sexual 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] Mesh networks are more flexible network architecture that 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 sending unnecessary communications 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 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 a direct neighboring node reaches the relay destination communication node, and by surrounding the transmission bottlenecks or failure, network response time can be improved, while minimizing the number of transmissions broadcast by the information needed to use the power and minimize network. 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 using determine priority between the network when there is a conflict, these common node can keep it as one of the communication schedule for 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。 Communication barriers can be attributed to the physical barriers, such as the natural obstacles (such as a mountain or a tree) or man-made obstructions (such as concrete structures) long distance, or network problems inherent logic, such as differences in 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 be located in different independent monitoring 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 the solution must be flexible, reliable and effective, and 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) connection gateway or radio repeaters, or home network rollout cable interconnect separate 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 device is 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 plant 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 sensors or actuators, or both caused by, and may control 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 based on the sensor / actuator application, without greater cost of installation, the network multiple devices must be powered locally, because the electric power facilities, such as 120VAC facilities or power data bus, not near, or not allowed to enter instruments, sensors and actuators as well as the security monitor or a human interface device must be located in a 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 sources (e.g., long-life battery or a fuel cell) or low power energy scavenging power source type (e.g., vibration, sunlight, or pyroelectric) 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 (as in the case of long-life battery) or generated (as in the case of solar panels in) limited power 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 of economic demand driving the need for a wireless field device networks of battery-powered device that communicates a 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 (if not the original rechargeable battery) 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 as long product life and sustained period of 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 network protocols by simply turn their own transponder limited amount of time to receive the information, any node or traffic restriction device during any period of time 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 turned on (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 a global duty cycle to save power such that the entire network simultaneously on and off. 其它协议(如, 基于TDM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, TDM-based protocols) can use the local work cycle, which links together only the correspondent node to be the scheduled time so as to open and close synchronously 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HART® )的TDMA)。 Typically, by this node to specify a specific and timely communication slot, by using an RF transceiver channel, who will receive and who will be sent at that time, a predetermined link (such as having a channel hopping protocol (such as wireless HART®) 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。 Oilfield comprising dispersed in a large number of regional drilling platform in a 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。 These isolated communication between the local area for the overall management of oil fields 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 the drilling platform network monitoring and control everything from the flow rate and temperature of the fluid to the valve 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 mechanisms to manage the production or prevent failures. 从每个隔离的钻井平台到中央监测站的本皇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 :Wireless Supervisory and Control Data Acquisition system)来将钻井平台连接在一起成星形网络。 Isolated from each rig to a central monitoring station of the cable may be impractical to beat Huang expensive, so commonly used to manage and control wireless acquisition system (SCADA: Wireless Supervisory and Control Data Acquisition system) to the drilling platform together a 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, with solar panels to power their backup battery. 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 may 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/杆式栗和棚屋。 The distance between the drilling platform is generally greater than the standard range of wireless field devices, and often physical barriers exist for wireless communication, such as earth station, tank, processing equipment, rocker / rod chestnut 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 by natural fabrics such as trees and bushes and the like. 树以约0. 35dB/m吸收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。 Tree of about 0. 35dB / m 2. 4GHz absorption spectrum radio transmission, rapid consumption link budgets in a wireless network using low-power radio equipment. 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 cover the distance between the 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 are usually distant location, rapidly approaching the limits of convenient power source. 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 more powerful transceiver quickly and rapidly absorb energy storage, and the pushing 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 distributed 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 point RF network) for each network link. 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 a 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。 Gateway or base station there is associated with additional cost, a gateway, or base stations are generally expensive and require 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 over a large area dispersed throughout the network 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 to install 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。 Transponder is powered devices, by which a higher power transmission and reception to the low-power signal such that the signal will overcome the obstacles and the distance it can be detected and the network is running. 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 operation of the transponder.

[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 a factor in overcoming barriers 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 interconnect 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 or via a passive RF power splitter two antennas each connected to the radio equipment. 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 use caused 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0. 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。 For example, LMR-400 low loss RF cable will cause about 0. 22dB / m at signal loss at 2. 4GHz and passive RF splitter will be available to reduce the RF signal strength in each half at the output. 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 be two interconnected networks, these networks and the signals so that the loss before the device must be very close to each 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 switching between the two antennas RF signal to recover some of the loss of signal, but the wireless device adds considerable complexity, and still left with the additional RF antenna cable associated with large losses.

[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, the power source 239 includes a local independent electrochemical source (eg, long-life batteries or fuel cells) at least one embodiment (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 is integrated into a 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, the local power source is physically separate but are electrically connected to provide an electronic connection to the wireless device.

[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 link. 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 wired link can severely limit the distance over 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 differences in network protocols, the implementation of FIG. 7A-7B regular meeting is 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, a wired link solely powered by the local power supply is connected to a wireless device. 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 and can be powered by an external source to 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。 In which the present invention is ideally suited for 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 wired link should be relatively high, at least it has a data rate of wireless protocols used to connect the same order of magnitude. 例如,采用无线HART%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, using a wireless data rate wireless HART% 250Kbits / sec, so a 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 is much better than a wired link power efficiency of the wireless link, a wired link may be slightly lower than the data rate wireless data rates, 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 of the local power supply of the present invention allows the wireless device is turned on (when they fast communications) and duty cycle between the closed and open time is minimized to reduce the average 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 devices via a network so that a single network manager to manage and control a combined network and directly asked on separate nodes by allowing the wireless field devices 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 available immediately, 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 near the route between the current network of 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 having a link comprising 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 requires only long enough to span the expensive long line of obstacles, avoid laying Internet backbone link or local links needed 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。 Because the wireless devices to easily be programmed using 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。 Using a plurality of wireless devices also allow the use of the present invention is to connect different network protocol network, makes it easier to manage, upgrade and expand the existing network of field devices.
