For better explanation, the embodiment of the testing device of the present invention is chosen to illustrate its working principle, but not to limit the scope of the present invention, as follows:

the first line interface 10 is connected to the electronic detonator by a non-polar detonator bus. The method comprises the steps of providing electric energy for the electronic detonator, writing detonation time, verifying detonation password, detecting detonator state, sending detonation command and the like. The bus voltage can be set by the voltage control unit 3 in the range of 5-28V with an accuracy of 0.1V. The test device detects the explosion impact signal of the electronic detonator through the vibration sensor, and sends the signal to the singlechip 2 after the signal is processed by the signal processing circuit 5 through filtering, amplification, transformation, comparison and the like. And at the zero moment of detonation, the singlechip 2 starts a timer for recording the time length from the initiation command to the initiation vibration signal, and the minimum measurement precision is 1us. And judging whether the precision of the electronic detonator meets the product standard or not by comparing the set detonation time with the actually measured time length. The electronic detonator is set to be delayed for 0 second, the output voltage is adjusted through the voltage control unit 3, the electronic detonator is detonated by utilizing the lifting method principle, the ignition condition of the electronic detonator is observed, and the maximum voltage capable of enabling 0.01% of ignition medicaments to be ignited and the minimum voltage capable of enabling 99.99% of ignition medicaments to be ignited are obtained.

Corresponding to the above, the utility model discloses test device's working process explains as follows:

It should be noted that, during the ignition test, if the electronic detonator fails to detonate, the timer of the single chip microcomputer 2 stops timing after the set detonation time exceeds 2s, and the test failure is prompted. And when the next electronic detonator test is carried out, the voltage is increased according to the principle of a lifting method, and if the electronic detonator is not detonated after the voltage is increased, the voltage needs to be increased again until the electronic detonator is detonated or the voltage is increased to the maximum limit voltage. And at this time, the voltage is required to be reduced when the next test is carried out, the voltage is increased until the electronic detonator is not detonated, and finally the maximum non-ignition voltage and the minimum ignition voltage are calculated according to a formula.
