背景技术Background technique
在进行配电自动化建设和应用过程中，主站和终端通信是配电自动化应用是否成功的关键因素，配电网运行状态的监视、控制和故障处理都依赖于通信网来实现，目前，采用EPON(以太网无源光网络)技术无疑是一个比较好的选择，但是由于城市建设和电力线路规划的原因，存在光缆施工困难等因素，因此考虑采用了无线通信方案来实现配网自动化数据采集，无线公网通信因其部署迅速、覆盖率高、不受地域限制等特点，在配电自动化应用越来越多。虽然无线公网通信方案优势明显，但同样存在一些缺点：通信延迟较大、通信稳定性差等等，因此在采用无线公网通信时，故障快速查找和定位，是采用无线公网通信成功与否的关键因素。In the process of distribution automation construction and application, the communication between the main station and the terminal is the key factor for the success of the distribution automation application. The monitoring, control and fault handling of the distribution network operation status all rely on the communication network to achieve. At present, the use of EPON (Ethernet Passive Optical Network) technology is undoubtedly a better choice, but due to urban construction and power line planning, there are factors such as difficulties in optical cable construction, so wireless communication solutions are considered to realize automatic data collection of distribution networks , Wireless public network communication has more and more applications in distribution automation because of its rapid deployment, high coverage, and no geographical restrictions. Although the wireless public network communication solution has obvious advantages, it also has some disadvantages: large communication delay, poor communication stability, etc. key factor.
由于无线公网通信涉及的环节较多，包括SIM卡、无线模块、移动无线网络、运营商内部链路及配置、供电公司接入网络及设备、安全设备、无线数采计算机、配电终端等，在出现通信故障时，对于供电公司内部的部分可以准确定位，但涉及到移动运营商部分的问题，难以查找和定位，目前，当出现通信故障时，维护人员首先查看相关的无线通信终端是否故障、通道是否故障、防火墙和路由器是否故障，再分析通信报文，查看上下行报文，分析出通信中断的具体时间和现象，往往会耗去1小时左右的时间。Since there are many links involved in wireless public network communication, including SIM cards, wireless modules, mobile wireless networks, internal links and configurations of operators, access networks and equipment of power supply companies, security equipment, wireless data acquisition computers, power distribution terminals, etc. , when a communication failure occurs, the internal part of the power supply company can be accurately located, but it is difficult to find and locate the part related to the mobile operator. At present, when a communication failure occurs, the maintenance personnel first check whether the relevant wireless communication terminal is Fault, whether the channel is faulty, whether the firewall and router are faulty, and then analyze the communication packets, check the uplink and downlink packets, and analyze the specific time and phenomenon of communication interruption, which usually takes about 1 hour.

首先，故障定位模块获得无线数据采集系统的无线模块业务通信状态，无线网管通信系统的无线模块网管状态、SIM卡状态、基站状态信息，然后无线模块与配电终端关联分析，由于配电自动化主站系统的实时数据配置包含配电终端的地址信息，无线数据采集模块包含无线模块的ID信息，因此只有建立配电终端地址和无线模块ID的关联关系，才能对配电终端异常原因分析。First, the fault location module obtains the wireless module business communication status of the wireless data acquisition system, the wireless module network management status, SIM card status, and base station status information of the wireless network management communication system, and then analyzes the correlation between the wireless module and the power distribution terminal. The real-time data configuration of the station system includes the address information of the power distribution terminal, and the wireless data acquisition module includes the ID information of the wireless module. Therefore, only by establishing the relationship between the address of the power distribution terminal and the ID of the wireless module can the abnormal cause of the power distribution terminal be analyzed.
在获得上述无线数据采集系统的无线模块业务通信状态，无线网管通信系统的无线模块网管状态、SIM卡状态、基站状态信息，配电自动化主站系统的状态和位置信息后，通过描述通信路径的关键节点设备信息和IP地址信息，采用ping包的方式，网络采集关键节点状态，关键节点状态包括供电公司防火墙、路由器、移动运营商内部关键节点状态。After obtaining the wireless module business communication status of the above wireless data acquisition system, the wireless module network management status, SIM card status, base station status information of the wireless network management communication system, and the status and location information of the power distribution automation master station system, by describing the communication path Key node equipment information and IP address information, using ping packets, the network collects the key node status, the key node status includes the power supply company firewall, router, and mobile operator's internal key node status.
通过分析ISO网络7层标准协议模型的第二层和第三层信息，提取数据包通过的路径和连接关系，建立一个网络通信路径的拓扑关系，同时利用SNMP协议、ICMP协议和ARP协议三种协议相结合的网络拓扑搜索算法，发现无线通信网络的链路层网络拓扑和提取网络的配置信息。By analyzing the second and third layer information of the ISO network 7-layer standard protocol model, the path and connection relationship through which the data packet passes is extracted, and a topology relationship of the network communication path is established. The network topology search algorithm combined with the protocol discovers the link layer network topology of the wireless communication network and extracts the configuration information of the network.
按照建立的通信拓扑关系，自动检测每个配电终端的通信状态，分析和定位故障节点。根据配电终端业务数据状态和网管数据状态进行关联和比对，分析故障类型，若网管状态正常而配电终端业务状态不正常，故障原因是配电终端部分，若网管状态和配电终端业务状态均不正常，故障原因是通信部分。然后通信部分再根据各关键节点的状态信息，确定故障的具体节点。According to the established communication topology relationship, the communication status of each power distribution terminal is automatically detected, and the fault node is analyzed and located. According to the correlation and comparison between the business data status of the distribution terminal and the network management data status, the fault type is analyzed. If the status of the network management is normal but the business status of the distribution terminal is abnormal, the cause of the fault is the distribution terminal part. If the status of the network management and the business status of the distribution terminal The status is not normal, and the cause of the failure is the communication part. Then the communication part determines the specific node of the failure according to the state information of each key node.
利用集成的配电自动化主站地理信息，在地理图上定位通信故障的地点。Use the geographical information of the integrated distribution automation master station to locate the location of the communication fault on the geographic map.
