Description
Technical field
The invention belongs to technical field of electric power communication, particularly relate to a kind of response formula electric power communication protocol automatic test approach based on configuration in power communication.
Background technology
In Automation of Electric Systems, power remote monitor substation has important effect, and completeness and the reliability of monitoring function are extremely important.Under the environmental condition that electric intelligent device is numerous, electric power communication protocol is also respectively have its self-defining version, or even same function communicates with monitoring substation as small current neutral grounding also has different communication protocols; Monitoring substation needs to realize communicating with electric intelligent device.When the current division of labor is clear and definite and device producer is numerous, program location and the intelligent apparatus location of exploitation usually can not in places, therefore developer is when doing communication protocol, the simple debugging acid of using function is manually debugged, the message information content provided to debugged program immobilizes, this differs too large with on-the-spot actual motion environment, cause communication protocol program not tested fully, there is uncertain hidden danger.
Summary of the invention
For the deficiencies in the prior art and shortcoming, for reducing this risk, the present invention seeks to be to propose a kind of response formula electric power communication protocol automatic test approach based on configuration, according to the request of monitoring substation, respond the correct dynamic message data of automatic generation, alleviate stipulations commissioning cost, to a certain extent approaching to reality Run-time scenario, reduce risk.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of response formula electric power communication protocol automatic test approach based on configuration, it is characterized in that, its method is: by defining message format and establishing message dynamic data algorithm, communication mode, response relation to map, according to the request of monitoring substation, response generates dynamic message data automatically, is automatically presented at the communication message mutual between communication protocol program and test program that monitoring substation is run.Message format is defined by message definition module to realize, and message definition module defines the algorithm needing dynamically to generate data simultaneously.Test program independently can be set as serial communication or TCP network service with the communication of the communication protocol program on monitoring substation.
Response relation specifies which type of data of communication protocol PROGRAMMED REQUESTS on monitoring substation, and which type of data test program should answer.
The present invention be used for simulation electric power protection or measure and control device automatically generate dynamic message; from the request of dynamic response from the communication protocol program run on supervisory control of substation substation; be applied to the test of electric power communication protocol program in telemechanical communication; by above-mentioned method; the monitoring substation that developer is write and the power communication program of measure and control device obtain relatively testing fully; improve the testing efficiency of developer, the program alleviating site operation personnel is to a certain extent installed, is debugged and maintenance work.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is flow chart of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figure 1, a kind of response formula electric power communication protocol automatic test approach based on configuration of the present invention, it is according to the request of monitoring substation, respond the correct dynamic message data of automatic generation, alleviate stipulations commissioning cost, to a certain extent approaching to reality Run-time scenario, reduce risk.It comprises message definition module, communication configuration module, response message mapping block and test program module; Wherein:
1, message definition module is the form for defining message, which specifies be dynamic data in message, specifies the algorithm of software test data generation, the type of dynamic data.
2, communicate configuration module; Communication mode is set, mainly serial communication and network service two kinds of modes.
3, response message mapping block; The message of which kind of type should be responded when the communication protocol PROGRAMMED REQUESTS of monitoring substation is set.
4, test program module; Test program module major function is: the tissue of the reception of communication protocol message and analysis, dynamically message also sends to the communication protocol program etc. of monitoring substation.This test module comprises:
Receiver module, receives and the message of the communication protocol PROGRAMMED REQUESTS of analysis monitoring substation;
Molded tissue block, generates the data needing dynamic change, and is organized into corresponding message, then send to the communication protocol program of the monitoring substation of request;
Message display module, to the display of question and answer message.
Test program and the communication protocol on monitoring substation are primarily of realizations such as serial ports or TCP networks.
The present invention is by above-mentioned module, and its response formula electric power communication protocol automatic test approach step realized based on configuration is as follows:
Based on a response formula electric power communication protocol automatic test approach for configuration, it is characterized in that: comprise method step as follows:
(1) message is defined; First be the form defining message, be used to specify the type which is dynamic data in message, dynamic data, the definition of dynamic region of variation and software test data generation algorithm in the implication of each byte position representative in message, message.In the present embodiment, dynamic region of variation refers to the monitoring bearing area of each signal of conveyer in message, substation, is also the data field in message.
(2) configuration communication parameter; By the definition message of step (1), corresponding communication mode is set; Monitoring substation is mapped with the messaging parameter of each device, the self-defined of message and response message and is all realized by configuration; This messaging parameter refers to and adopts serial communication or the network communication mode based on TCP/IP;
(3) response message maps; Communication protocol PROGRAMMED REQUESTS on monitoring substation and the mapping relations of test program response message, namely when monitoring the communication protocol program on substation and sending request message, test program should respond corresponding message, and these mapping relations are realized by configuration communication parameter;
(4) operation of autotest program; First the operation of test program, receives and analyzes the message from monitoring substation communication protocol program, organizing corresponding message, then the request of response monitoring substation communication protocol program; Last question and answer message display, namely shows and resolves the various information of transmiting and receive telegrams represented by literary composition and message content thereof.
The present invention be used for simulation electric power protection or measure and control device automatically generate dynamic message; from the request of dynamic response from the communication protocol program run on supervisory control of substation substation; be applied to the test of electric power communication protocol program in telemechanical communication; by above-mentioned method; the monitoring substation that developer is write and the power communication program of measure and control device obtain relatively testing fully; improve the testing efficiency of developer, the program alleviating site operation personnel is to a certain extent installed, is debugged and maintenance work.
