The invention discloses a circuit safety management method, which is applied to a circuit breaker. The circuit safety management method comprises the following steps: collecting circuit parameters through a built-in sensor; analyzing current power consumption of the circuit based on the circuit parameters, and obtaining an analysis result; coding the circuit parameters and the analysis result by using a preset communication data structure; and uploading the encoded data to an Internet terminal through a built-in communication module, so that the Internet terminal performs safety management onthe current circuit. The invention also discloses a circuit breaker and a computer readable storage medium. The invention realizes the intelligent monitoring of the power consumption condition of thecircuit, and further achieves the safety management of the circuit and improves the safety of the electricity.
