1. The system has the characteristics of higher reliability, higher cost-effectiveness, and higher practicality. It can quickly respond to users' simulated operations such as switches and knives, accurately judge the correctness of operation actions, and issue warnings in a timely manner in case of erroneous operations!

2. The system adopts an expandable and functional area design, with a built-in expandable PLC as the system command center and a complete communication function design. Its bus based architecture features make the cable distribution structure of the entire system simple and clear, and easy to maintain.

3. The system has logical interlocking and high intelligence, which can realize the networking, communication and other functions of on-site power facilities, simulate the logical relationship of on-site equipment, and provide remote monitoring.

4. The symbols for high and low voltage busbars, transformers, etc. in the system diagram are illuminated by LED lights. The busbars light up when they are energized and turn off when they are not. Simulate switches, knives, etc. to emit a red signal when closed and a green signal when disconnected. Equipped with independent calendars, clocks, and safety operation instruments, it has the function of saving power-off data.

5. The intelligent central signal alarm device adopts a central reset function to filter and process repeated accident signals and warning signals for accurate judgment. The signal alarm device is equipped with RS485/232 communication interface and adopts standard Modbus master/slave protocol. Equipped with automation system backend control and reset functions (automatic system reset, manual reset, and analog screen panel reset).
