According to the device provided by the invention, the actual operation adaptability of the terminal can be effectively verified; truthful data of each link based on data transmission is adopted to be compared automatically so as to realize all-directional multi-angle automatic test; and data from different sources is subjected to automatic reading and comparing, so that both the testing efficiency and the quality are improved. Therefore, the intelligent terminal testing device provided by the invention has strong practical significance.

Description

technical field [0001] The invention relates to terminal testing technology, in particular to a measurement automation intelligent terminal testing device. Background technique [0002] During the daily operation and maintenance of data acquisition terminals, it is often found that after the terminals that have passed the laboratory test are installed on site, there are problems in the master station’s data copying, and the specific responsibilities are difficult to define. I don’t know whether it is a communication problem or the test platform software. The problem, or the problem of the master station of the metering automation system. [0003] In order to ensure accurate and reliable measurement and clear division of responsibilities, operation and maintenance personnel usually bring the terminals that have problems judged by the master station system to the laboratory for testing. During the test, not only the relevant information of the terminal is obtained through the...

Problems solved by technology

[0008] However, the above-mentioned traditional terminal test device communicates with the terminal through the analog meter to test the compatibility of the terminal downlink message, and the standard message of the analog meter is generated by the analog master station, which is actually manually set. The simulated meters are all consistent, but the accuracy and compliance of the messages of the actually delivered and running electric energy meters need to be verified. Therefore, this method cannot discover the communication capabilities and meter reading capabilities between the terminal and the actual operating electric energy meters.

Moreover, the message analysis of the simulated master station cannot represent the real situation of the running master station, which leads to the fact that the terminal that has passed the simulated master station test and is correct may still have the problem of incompatibility between the terminal and the actual running master station in actual operation.
