Using standard racks and intelligent test software to build module interchangeability testing equipment, it is mainly used in the ability to test the interchangeability of carrier modules, GPRS modules, and micro-power modules from different manufacturers with standard acquisition terminals. Detect and evaluate the operation quality of the electricity information collection and communication modules supplied by different manufacturers. In the future promotion and application of smart electric energy meters, collection terminals and carrier communication modules, guide all units to make corresponding plans for different operating environments and regions Model selection to ensure the success rate of equipment information collection in operation.
