Level, remove redundant information, facilitate installation and operation and maintenance, design the power consumption information collection terminal into multiple modules with independent functions, and form different functional expansions through the combination of modules. It is the core product of a new generation of electricity consumption information collection system.

The energy controller has a total of 5 external module interfaces, which can be equipped with five different functional modules at the same time to meet business functional requirements. Each functional module is an independent power supply and an independent communication channel, and the communication between the functional module and the energy controller body is through the USB bus. The functional modules of the energy controller can be divided into remote communication modules (such as 4G communication modules, 5G communication modules, etc.), local communication modules (such as power line carrier communication modules, micro-power wireless communication modules, RS-485 communication modules, M-Bus communication modules, etc.) Communication module, CAN communication module, etc.), control module, remote signal pulse module, loop status inspection module, etc. At present, the functional modules are installed on the main board of the energy controller for testing. The test software cannot directly communicate with the functional modules, and can only test each functional module one by one by operating the main board of the energy controller. This test method has low efficiency and large workload. Each test station needs to be equipped with an energy controller motherboard, which also increases the cost and is inconvenient for maintenance.
