Sex, reliability and stability have truly achieved unattended goals.
3) Field device layer
The field device layer is a data acquisition terminal, which is mainly composed of smart meters. The smart meter connects to the communication server through the shielded twisted pair RS485 interface, and uses the MODBUS communication protocol bus type connection to reach the communication server through the communication server to realize the networking. remote control.
Smart meter field connection
The field instrument is connected by hand-shielded through the shielded twisted pair cable (RVVSP2*1.0). The number of smart meters connected to each bus is about 24, and then the data is uploaded to the serial port server NPORT5630-16, and the data is uploaded to the local monitoring. terminal. The specific connection diagram is as follows:
