The invention discloses novel integrated equivalent equipment for initiating explosive devices and an equivalent testing method of the initiating explosive devices. The equivalent equipment comprisesa testing system control module (1), a thermal battery activating signal collecting module (2), an engine ignition signal collecting module (3), a fuze input signal collecting module (4), a signal testing result display module (5) and a fuze switch function simulating module (6). In this way, through one core controller, the working time sequences of several kinds of initiating explosive devices in a system can be simulated completely while circuit features of each kind of initiating explosive devices can be equivalently simulated; the test coverage is remarkably improved for the initiating explosive devices, the problem is solved that in the prior art, the working time sequences are judged by human when a distributed testing means is used, and errors caused by human judgment are avoided.
