Method of testing robustness of closed loop protocol based on semantic analysis of dynamic script

Abstract

The invention discloses a method of testing robustness of a closed loop protocol based on semantic analysis of a dynamic script, including steps of: building a test environment; conducting signal interaction between a smart telecontrol device and a protection device and a measuring and control device, receiving data signals coming from the protection device and the measuring and control device, and conducting information interaction with automatic testing software through a remote transmission communication protocol; using the automatic testing software to conduct output control over a tester through dynamic script language to make the protection device and the measuring and control device to send and transmit signals to the smart telecontrol device; sequentially controlling testing process of the smart telecontrol device by the automatic testing software, receiving messages delivered by the smart telecontrol device and using dynamic script to analyze the messages from the smart telecontrol device so as to produce a test report. The method makes it possible to flexibly compile and edit a test case and the test report, is universally applicable and significantly improves the testing efficiency and the correctness and reliability of the test result.

Description

[0001] Technical field [0002] The invention involves the field of power communication technology, especially in the test analysis of the power communication regulations test analysis. Background technique [0003] With the rapid development of society, the stability and health requirements of smart grids are getting higher and higher, and the requirements for dispatching main stations have become higher and higher. As a smart grid terminal device RTU, it is the main device for station communication.Fast and stable communication is particularly important.Therefore, for their dynamic manufacturers, the new remote device needs to conduct a comprehensive test of the terminal RTU before entering the network. With more and more detailed and diversified needs, there are more and more functional points for communication regulationsThe traditional test method is not only large but also boring, it is easy to generate blind spots. New large -scale test methods are urgently needed. It also...

Problems solved by technology

Therefore, for each automation manufacturer, the new telecontrol device needs to conduct a comprehensive test on the application function and communication reliability of the terminal RTU before entering the network. With more and more detailed and diversified needs, the function points of the communication protocol are also increasing. , the traditional testing method is not only heavy workload but also boring, easy to produce blind spots, new large-scale testing methods are urgently needed, and higher requirements are put forward for new testing methods. Guarantee the safe and stable operation of the smart grid

[0004]At present, for various electric power automation manufacturers, the test of intelligent telecontrol devices is to build a small substation environment and increase the amount of secondary equipment such as protection, measurement and control through experiments. Manually check the correctness of the information one by one at the simulated master station. For the verification of new functions, not only new function items must be tested, but also a large number of regression tests. For reverse tests, abnormal messages and other methods are used to The robustness of the verification program also requires a lot of human resources. For this test mode, not only the work is cumbersome, but the workload is huge

and correctness cannot be guaranteed
