Description

technical field [0001] The invention belongs to the field of local communication of an electricity consumption information collection system, and relates to a broadband micropower wireless protocol interoperability testing system of the electricity consumption information collection system. Background technique [0002] At present, the local communication methods of the electricity consumption information collection system of power users mainly include power line carrier, micro-power wireless communication, etc. In order to improve the node access rate, communication speed, coverage and reliability of the local communication network, the State Grid is studying the integration of broadband power lines Dual-mode communication technology of carrier and broadband micropower wireless. At present, the broadband micropower wireless protocol standard is being formulated and improved, and the protocol development is also proceeding simultaneously. In order to speed up the protocol de...

AI Technical Summary

Problems solved by technology

[0003] The current testing of traditional micro-power wireless protocols mainly focuses on protocol conformance testing and point-to-point interoperability testing, and the protocol standards are different. The existing related protocol interoperability testing systems mainly have the following defects: (1) There are many testing methods It is a passive interoperability test, that is, it only monitors the behavior of the system under test and cannot control the system under test

(2) The test system is independently distributed in different systems, the test process is difficult to synchronize, the test data sharing rate is not high and the resource utilization rate is high

(3) The degree of automation of the test system is not high. For example, the test system cannot automatically obtain the latest protocol code and compile it during the protocol development stage; the test logs are scattered, and it is impossible to automatically analyze the test logs and notify the developers of test bugs in a timely manner.

(4) When the test scene changes, there will be communication compatibility problems between the test system and the system under test
