[0031] 下面根据说明书附图,对本发明的技术方案作进一步详细说明。 [0031] The following figures according to the instructions on the technical aspect of the present invention will be described in further detail.

[0032] 本发明提出了一种电力自动化系统前置系统通道级的冗余备份、负载分担的分层动态路由方法。 [0032] The present invention provides a redundant backup power automation system channel front-end system-level hierarchical routing method of dynamic load balancing.

[0033] 通过逻辑的分层设计实现真正通道级的冗余备份,在前置系统中引入了逻辑分层的设计模式,最底层是通讯介质的设备管理层,向上依次是框架层,规约解释层,数据处理层。 [0033] through a logical hierarchical design redundancy true channel level, the introduction of a logical hierarchy of design patterns in front-end system, the lowest level is the device management communications media followed up the framework layer, the statute interpretation layer, data processing layer.

[0034] a)逻辑分层处理 [0034] a) a logical hierarchical processing

[0035] 1)设备管理层 [0035] 1) Device Management

[0036] 如图2所示为本发明方法使用的设备管理示意图,设备管理层完成对所有设备对象的状态监控和数据的收发处理。 Device Management [0036] As shown in Figure 2 the present invention, a method using a schematic, equipment management complete transceiver processing for all devices to monitor the status of objects and data. 由于前置系统访问的通讯设备种类很多,为了屏蔽不同采集设备的软硬件差异,方便系统上层使用,对不同设备分别建立一个设备类。 Because many types of front-end system to access communications equipment, in order to shield the differences of different hardware and software acquisition devices for easy system to use the upper, respectively, for different devices to create a device class. 系统提供通讯接口基类,每一种通讯接口类型做为子类实现。 The system provides communication interface base class, each type of communication interface as a subclass implementation. 每一种类型的通讯接口均提供打开,关闭,读写操作等访问方法。 Each type of communication interface offers open, close, read and write access method operation.

[0037] 底层通讯设备库的设计,很好的实现了设备的扩展和维护。 [0037] The underlying communications device library designed to achieve a good extension and maintenance of the equipment.

[0038] 2)框架层 [0038] 2) frame layer

[0039] 框架层的实现主要涉及通道的管理,结合各种应用的数据传输特性,系统支持多种运行方式,如事件触发方式的读写解释模式,也支持定时方式的读写解释模式,每个通道可以单独管理,也可统一管理。 [0039] implementation framework layer mainly related to management channel, combined with the data transmission characteristics of the various applications, the system supports multiple operation modes, such as read and write to explain the event trigger mode, timer mode supports read and write explanatory model, each channels can be managed separately, can also be unified management.

[0040] 3)规约层 [0040] 3) of the Statute layer

[0041] 在前置系统的设计中,通讯规约是种类最繁杂而且变化最多的。 [0041] In the design of front-end system, the communication protocol is the most complex and species change the most. 因此通讯规约类库的设计最重要的在于抽象基类的设计,抽象基类给出了独立于类数据及其内部操作的与用户的公共接口。 Therefore, the design of communication protocol library is the most important abstract base class design, abstract base class is given independent of the type of data and its internal operations with the user's public interface. 类的公共接口定义了存取数据的方法,尽管类的内部实现改变后,用户也可保持原有的公共接口不变。 Public interface class defines the data access method, after the change despite internal class implementation, users can maintain their public interface unchanged. 这样,即使增加新的规约,只要保持接口不变,规约内部的实现可以封装起来,方便通讯规约扩展。 Thus, even adding new statute, just keep the same interface, the internal realization of the Statute can encapsulate facilitate communication protocol extensions.

[0042] 通讯规约类主要功能是完成对各种通讯规约进行数据解释、数据封装,方便通讯服务进程FEP操作、调用。 [0042] The main function of communications statute is to complete a variety of communication protocols for data interpretation, data encapsulation, convenient communications service process FEP operation, called. 规约基类以及所有扩展出的子类被封装在动态连接库中,形成系统的规约解释库。 Statute of the base class and all extensions of the subclasses are encapsulated in the dynamic link library, interpretation of the statute forming system libraries.

[0043] 4)数据处理层 [0043] 4) Data processing layer

[0044] 规约解释后的数据,按照电力应用数据类型分类发送到各自的应用服务器。 Data [0044] interpreted the statute, according to the data type classification power applications sent to the respective application server. 如对调度自动化的四遥信息,发送到DPservice处理,对保护告警和动作信息发送到RELAYSERVICE 处理,遥控信息发送到C0NTR0LSERVICE。 As for scheduling automated four remote information sent to DPservice treatment, protection alarm and motion information is sent to RELAYSERVICE processing, sending information to remote C0NTR0LSERVICE.

[0045] 每一个通道有一个当前控制节点;每一个RTU有一个主通道。 [0045] Each channel has a current control node; each RTU has a main channel. (默认优先级最高的通道为主通道)。 (Default highest priority channel as a master channel). 通道的当前控制节点完成通道的上送数据进入实时库,及系统应用的控制命令下行至RTU。 On completion of the current control node passage channel to send data into the real-time database, and application control command system down to the RTU. 另外,一个通道还可以具备另一个非控制节点,非控制节点可以接收通道数据,但不写入实时库,也不下发控制命令。 In addition, a channel can have another non-control node may receive a non-control channel data node, but not written to the real-time database, the control command is not issued.

[0046] 如图3所示为本发明方法使用的通道级冗余备份示意图,如果一个采集装置(如RTU)通过两个通道分别接到两个前置服务节点(FEP)上,如RTU2通过C3接到FEP1,通过C5接到FEP2。 [0046] channel level redundancy method of the present invention shown in the diagram in Figure 3 uses, if a collection device (such as RTU) through two channels are connected to the two pre-service node (FEP) on such RTU2 by C3 received FEP1, through C5 received FEP2. 一个FEP节点发生故障时,另一FEP节点则将此RTU的主通道变更为另一通道。 FEP when a node fails, another node if this RTU FEP primary channel is changed to another channel. 如FEPl故障退出,则FEP2将RTU2的主通道设置为C5,RTU2保持正常接入。 As FEPl fault Exit, the FEP2 will RTU2 main channel is set to C5, RTU2 maintain normal access.

[0047] 当发生FEP节点故障时,如果一个RTU只有一个通讯通道,则系统通过通道叉分机制,在主站端将一个通道接入两个FEP节点。 [0047] When a node failure occurs FEP, if an RTU only one communication channel, the system through the bifurcating channel mechanism, the master will be a channel access to both ends of FEP nodes. 如通道C8在主站端接入FEP2、FEP3两个节 The channel C8 in the master-side access to FEP2, FEP3 two sections

点ο Point ο

[0048] 系统正常运行时,C8的控制节点为FEP3。 [0048] During normal operation, C8 control node FEP3. 当发生FEP3节点故障时,FEP2将通道C8的控制节点改为FEP2,C8通道仍正常运行。 When a node failure occurs FEP3, FEP2 the control node channel C8 changed FEP2, C8 channel is still running.

[0049] 启动时一个通道有哪些节点可以打开:一般情况下,一个通道只有一个FEP节点打开。 [0049] When you start a channel which nodes can be opened: Under normal circumstances, a channel only one FEP node opens. 但是如果是UDP组播通道、或具备通道叉分装置,则一个通道可由两个或多个FEP节点打开。 But if UDP multicast channel, or channels with a fork separation plant, is a passage by two or more nodes FEP open. 但一个通道在某一运行时刻只能有一个控制节点。 But one channel at a time, only one run control node.

[0050] 故障时一个通道有哪些节点可以打开:当一个前置节点故障情况下,其所控制的各RTU通道会失去控制节点,则在所有前置节点列表中,故障前置节点的下一前置节点负责打开已成为孤立的RTU通道。 [0050] when the failure of one channel which nodes can be opened: when the next pre-node failure, it controls each RTU channel will lose control node in the node list of all the front, the failure of the pre-node next Pre-node is responsible for opening the RTU channel has become isolated.

[0051] 在如图3所示的通道连接关系中,RTUl有三个通道与主站系统相联(两个通道由FEPl管理,一个通道由FEP2管理)。 [0051] In the channel as shown in Figure 3 is connected relationships, RTUl three channels associated with the master system (both channels by the FEPl management, a channel consists FEP2 management). RTU4有一个通道与主站系统相联,但FEP2、FEP3均可打开此通道(如通过串口服务器切换装置,或一个通道具有两个设备地址)。 RTU4 there is a channel associated with the master system, but FEP2, FEP3 can open this channel (such as a switching device through the serial port server, or a channel with two device address).

[0052] 则在通道参数表中,具有8条通道。 [0052] in the channel parameter list, with eight channels. 其中,C1/C2/C3的控制节点为FEPl,C4/C5/C6 的控制节点为FEP2,C7/C8的控制节点为FEP3。 Wherein, C1 / C2 / C3 of the control node FEPl, the control node C4 / C5 / C6 is FEP2, the control node C7 / C8 is FEP3.

[0053] 同时,对一个RTU具有的多个通道,配置每个通道的优先级,如RTUl的三个通道。 [0053] Meanwhile, the RTU has a plurality of channels, each channel configurable priority, such as the three channels RTUl.

[0054] [0054]

Figure CN101588295BD00061

[0055] 系统启动时,FEPl打开C1/C2/C3通道,FEP2打开C4/C5/C6通道,FEP3打开C7/ C8通道。 When [0055] the system starts, FEPl opens C1 / C2 / C3 channel, FEP2 open C4 / C5 / C6 channel, FEP3 open C7 / C8 channels. 系统启动后,C1/C2/C3的控制节点为FEP1,C4/C5/C6的控制节点为FEP2,C7/C8 的控制节点为FEP3。 After the system starts, C1 / C2 / C3 of the control node FEP1, the control node C4 / C5 / C6 is FEP2, the control node C7 / C8 is FEP3.

[0056] FEPl通过Cl通道对RTUl进行控制,通过C3通道对RTU2进行控制。 [0056] FEPl by Cl channel on RTUl controlled by C3 channel of RTU2 control.

[0057] FEP2通过C6通道对RTU3进行控制。 [0057] FEP2 through C6 passage of RTU3 control. [0058] FEP3通过C8通道对RTU4进行控制。 [0058] FEP3 through C8 passage of RTU4 control.

[0059] 2、前置节点、节点组模式的数据分流方法 [0059] data distribution method, the pre-node, node group mode

[0060] 如图3所示,有两个FEP节点,FEPl接入RTUl和RTU2,FEP2接入RTU3和RTU4,在FEPl和FEP2之间实现了负载分担。 [0060] shown in Figure 3, there are two FEP nodes, FEPl access RTUl and RTU2, FEP2 access RTU3 and RTU4, between FEPl and FEP2 achieving load balancing. 这是常规的一种前置分流技术。 This is a conventional front-streaming technology.

[0061] 而如图4所示,系统配置了两个前置机组,FEPl和FEP2为一个前置机组,接入RTU1/RTU2/RTU3。 [0061] and shown in Figure 4, the system is configured with two front units, FEPl and FEP2 as a front unit, access RTU1 / RTU2 / RTU3. FEP3和FEP4为一个前置组,接入RTU4/RTU5/RTU6。 FEP3 and FEP4 as a front group, access RTU4 / RTU5 / RTU6. 两个前置机组独立工作,实现负载分担。 Two front units work independently, to achieve load balancing.

[0062] 在前置机组1内,FEPl和FEP2冗余备用。 [0062] in the front unit 1, FEPl and FEP2 redundant backup.

[0063] 在前置机组2内,FEP3和FEP4冗余备用。 [0063] in the front unit 2, FEP3 and FEP4 redundant backup.

[0064] 在前置机组1或者2整体出现故障的极端情况时,其它的前置组则可以完全接管改组的处理工作,从而使得可靠性提高了一级。 [0064] When the pre-set 1 or 2 overall failure in extreme cases, the other pre-set, you can completely take over the work of the restructuring process, so that increases the level of reliability.

[0065] 整体架构如图1所示,实现了采集装置、通道、前置节点间的多层动态路由技术。 [0065] the overall architecture shown in Figure 1, to achieve a multi-layer dynamic routing technology acquisition device, channel, front nodes.
