Background technology
The communication technology is the key technology that intelligent substation realizes automation mechanized operation, the unification of communication protocol and compatibility, is conducive to the interchangeability and the interoperability that realize equipment in transformer substation system.In substation communication network system; general employing protocol converter carries out the conversion of communication protocol; carry out data communication by the serial line interfaces such as RS232/485 and the terminal equipment such as relaying protection, measure and control device, the communication protocol standard of being specified according to user by Ethernet interface after protocol conversion process is sent to supervisory control system.Along with the raising of intelligent substation level, the communication protocol transducer being applied to substation communication network system must ensure reliable and stable, and has certain flexibility, ease for maintenance and extensibility.General protocol transform function is realized by programming language, editor's compiling generator, this way can only adapt to specific stipulations, if stipulations change must write compiler again, causes occurring in protocol transform that efficiency is low, very flexible and be difficult to ensure the problem that card program is stable.
Summary of the invention
The object of this invention is to provide a kind of IEC61850 stipulations and the configurable conversion method of TCPModbus stipulations, the efficiency at present realizing occurring in communication protocol conversion at programming language be low to solve, the problem of very flexible.
The present invention is for solving the problems of the technologies described above and providing a kind of IEC61850 stipulations and TCPModbus protocol transform method, and this conversion method comprises the following steps:
1) according to IEC61850 modeling standard to corresponding function point modeling, and form the period table corresponding with model;
2) according to the translation-protocol of IEC61850 stipulations and TCPModbus stipulations, the relation mapping table of period in the period in configuration period table and TCPModbus agreement;
3) protocol transform task the interactive interface of initialization and IEC61850 task is created, by relation mapping table configuration specification convert task;
4) create IEC61850 task the interactive interface of initialization and protocol transform task, configure IEC61850 task with the model file created;
5) conversion of IEC61850 stipulations and TCPModbus stipulations is realized according to configured protocol transform task and IEC61850 task.
Described step 1) in the period table that generates for providing source of configuration file for IEC61850 task.
Described step 2) in relation mapping table be used for providing configuration file document source for protocol transform task.
Described step 3) with step 4) in the IEC61850 task that creates create two titles identical uplink and downlink one-level, secondary queue separately with protocol transform task, receive from two queues respectively and send data.
The invention has the beneficial effects as follows: the present invention by introducing configurable conversion plan in the conversion of IEC61850 stipulations and TCPModbus stipulations, according to IEC61850 modeling standard to corresponding function point modeling, and automatically form the period table corresponding with model, according to the translation-protocol of IEC61850 stipulations and TCPModbus stipulations, the relation mapping table of the period in configuration IEC61850 period table and the period in TCPModbus agreement, utilize relation mapping table and model configuration file configuration specification convert task and 61850 tasks respectively, the communication of supervisory control system and terminal equipment is realized according to configured file.If stipulations change, only need the relation mapping table of modifier model and correspondence thereof, reconfigure 61850 tasks and protocol transform task, do not need update routine, greatly reduce workload like this, improve efficiency, avoid the risk because modification of program brings.
Accompanying drawing explanation
Fig. 1 is configuration mapping relations flow chart of the present invention;
Fig. 2 is the flow chart of protocol transform work of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
Protocol transform function in the present embodiment connects terminal equipment by RS-485 serial ports, and the information about power, state information etc. of collection terminal equipment are also converted to IEC61850 stipulations agreement by Ethernet interface and are connected with supervisory control system; Connect supervisory control system by Ethernet interface, divide into the remote regulating such as remote information, the analog quantity parameter information such as open and close machine and be converted to TCP Modbus stipulations agreement by RS-485 serial ports control terminal, as shown in Figure 2.Concrete steps are as follows:
1. first according to user's request, according to IEC61850 modeling standard, IEC61850 modeling is carried out to corresponding function point, and automatically form the period table corresponding with model, for IEC61850 task provides configuration interface file.
2. according to the translation-protocol of IEC61850 stipulations and TCPModbus stipulations, the relation mapping table of period in the period in configuration period table and TCPModbus agreement.The point needing association is found at period table, in relevant parameter, select the information such as communication type, communication position, mask, displacement, coefficient of period corresponding in TCPModbus protocol massages, operated by associated configuration, generate the mapping relations table between this two period, configuration interface file is provided without convert task, as shown in Figure 1 for being attributed to.
3. create protocol transform task and the interactive interface of initialization and 61850 tasks, by relation mapping table configuration specification convert task, to realize the communication connection with terminal equipment.
