It is responsible for data processing and algorithm computing, can process a large amount of data generated during the operation of the equipment in real time, and respond quickly according to the preset control logic. It is also responsible for communicating and exchanging data with other modules to ensure that the entire device can work together;

[0022] The communication unit supports multiple communication protocols (such as Ethernet, RS485, Modbus, etc.) and is used for real-time communication with the upper-level system (such as DTU terminal). It is responsible for receiving the control instructions and parameter settings of the upper-level system, and uploading the operating status and fault information of the equipment to the upper-level system, so that the main control module can realize remote monitoring, remote maintenance and remote upgrade functions, thereby realizing a high degree of integration of the primary circuit and the secondary circuit at the information level, making information transmission more efficient, and the system can respond to external changes more quickly, thereby improving operating efficiency;
