Title: CIRCUIT-BREAKER CONTROLLER AND CONTROL METHOD
Abstract:
Provided are a circuit-breaker controller and control method, comprising: a data-read and signal-detection step (S102); reading data from a fast-read storage device, and detecting an MCR/HSISC state signal by means of an MCR/HSISC detection circuit; a function selection step (S104); selecting whether to execute an MCR function or an HSISC function, said selection being made on the basis of whether a jump is present in the MCR/HSISC signal; executing the MCR function (S106) or executing the HSISC function (S108); if the conditions for execution are satisfied, then performing a trip, and ending the process; if a termination condition is encountered during the process of execution, then ending the process. Also provided is a circuit-breaker controller for implementing the described control method. The circuit-breaker controller and control method use software to perform the MCR/HSISC functions, and have an advantage in terms of cost of implementation and detection stability; the controller is provided with an MCR/HSISC detection circuit and a fast-read/write storage-device circuit, allowing for fast startup of the controller and fast writing prior to power loss.
