Abstract: Electricity Information Acquisition System (EIAS) test platform is used to evaluate the communication performance of the different communication methods. For realizing the reliable and quick information interaction in the test terminal, a hierarchical structure multi-network convergence communication mechanism is designed. The convergence communication mechanism is divided into the communication interface convergence layer, the core convergence layer and the business convergence layer to realize the information interaction among the Ethernet communication, power line carrier communication, RS-485 communication and wireless communication. Combined with the tunnel transmission mechanism, the buffer pool mechanism, the communication check mechanism and the timeout control mechanism, the multi-network convergence communication mechanism can effectively improve the communication performance of the test terminal. The test results show that the mechanism can satisfy the real-time and reliability requirements for the electricity information acquisition system test platform.


Keywords: Electricity information acquisition system, Multi-network convergence communication, Hierarchical structure, Information interaction, Test platform.
