The specific embodiment
Embodiments of the invention: the detection method of electric detonator medicine head welding quality, checkout gear earlier send look-up command to electric detonator, electric detonator receive this instruction afterwards the address of this detonator and defer time to the checkout gear loopback and be in the reception command status; After checkout gear receives the electric detonator feedack, opening one is lower than the detonate electric current of voltage of electric detonator and continues to power to electric detonator, this electric current is flow through the pressure drop and the reference voltage that form behind the medicine head of electric detonator compare, can determine the welding quality of this electric detonator medicine head.
The structure of the checkout gear of electric detonator medicine head welding quality as shown in Figure 1, the structure fabrication of circuit module goes out benchmark voltage module 1 and circuit amplification module 2 routinely earlier, input and the positive source of benchmark voltage module 1 are coupled together, its output is connected on the input positive pole of circuit amplification module 2, input negative pole at circuit amplification module 2 is connected with medicine head link block 3, is connected with detonator body control module 4 at the output of circuit amplification module 2; The control end of signal identification module 6 is connected with detonator body control module 4; The electronic switch 5 that connects the control end connection of a detonator body control module 4 in medicine head link block 3; Positive pole at power supply is connected with a charging circuit 7, and the other end of charging circuit 7 is connected with detonator body control module 4, benchmark voltage module 1 and electronic switch 5; And connecting a storage capacitor 8 at the output of charging circuit 7, the other end of storage capacitor 8, detonator body control module 4 and medicine head link block 3 all is connected with power cathode; Signal identification module 6 is connected with power supply; Between the both positive and negative polarity of power supply, also connect an over-voltage protection module 9 in parallel with signal identification module 6.All adopt the various custom circuit modules of prior art to get final product with upper module.
