The dual-mode heterogeneous detection system can test the main performance parameters of the dual-mode heterogeneous local communication unit. According to the relevant standards and technical specifications of the grid company, it performs a series of unified technical specifications and communication protocol tests for the network link and its node units. So as to implement systematic indicator detection and evaluation. It can effectively improve the stability, reliability and scalability of the power user information collection system, and is of great significance to the realization of the goal of "full coverage, full collection, and full cost control".
