Testing device and method for safety monitoring system

The invention provides a testing device and a method for a safety monitoring system, and relates to the technical field of coal mine safety. The testing device comprises a control module, a data transmission module, a power-off execution module and a power-off detection module, the control module is used for generating a corresponding test signal according to a to-be-tested power-off locking function type; the data transmission module is used for transmitting the test signal to the safety monitoring system and transmitting a control signal generated by the safety monitoring system based on the test signal to the control module; the power-off execution module is used for executing a power-off action according to the control signal; the power-off detection module is used for detecting contact state information of the power-off execution module; and the control module is also used for judging whether the power-off locking function of the safety monitoring system is effective or not according to the test signal a
