[0041] In the application, the electronic control module can simulate discharging of the firing element with different capacitances and different voltages, and the camera can dynamically capture the temperature and firing state of the firing element at the discharging moment of the firing element, and then can analyze the instantaneous temperature state, firing direction, firing height and the like according to the captured information, so as to determine whether the electronic control module is suitable for the client primer.

[0042] The application has reasonable design, simple connection and reliable operation, can effectively evaluate the adaptation of the electronic control module and the primer, and does not need to go to the client to do the primer adaptation experiment, so it is efficient and safe.

[0043] According to the common ignition agent, certain adaptation data and experience are accumulated, the firing impulse, the adaptation voltage, the unique firing property of the agent itself and the design of the electronic control module, the matched detonation system, the electronic control module related performance technical requirements in the WJ9085-2015 'industrial digital electronic detonator' and 'electronic detonator electronic control module access safety technical requirements' (trial) standard are combined, and the adaptation result of the firing performance parameter in step five and the ignition agent is comprehensively determined.
