| Abstract: | In order to meet the needs of low voltage electrical apparatus communication function, a design method of intelligent circuit breaker based on Modbus RTU protocol was proposed. The system components and the principle of intelligent controller were discussed. The realization methods of the communication module were introduced in detail ,including the design of interface circuit, Modbus frame processing and program design of data checking. The test resahs show that the intelligent low voltage circuit breaker has advantages of accurate communication function, reliable protection, and the properties of strong anti-interference. |
