Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Embodiment
The embodiment of the utility model: the structure of the pick-up unit of electric detonator medicine head welding quality is as shown in Figure 1; Structure fabrication by the custom circuit module goes out benchmark voltage module 1 and circuit amplification module 2 earlier; The input end and the positive source of benchmark voltage module 1 are coupled together; Its output terminal is connected on the input positive pole of circuit amplification module 2; On the input negative pole of circuit amplification module 2, be connected with medicine head link block 3, on the output terminal of circuit amplification module 2, be connected with detonator body control module 4; The control end of signal identification module 6 is connected with detonator body control module 4; The electronic switch 5 that on medicine head link block 3, connects the control end connection of a detonator body control module 4; On the positive pole of power supply, be connected with a charging circuit 7, the other end of charging circuit 7 is connected with detonator body control module 4, benchmark voltage module 1 and electronic switch 5; And on the output terminal of charging circuit 7, connecting a storage capacitor 8, 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 parallelly connected with signal identification module 6.All adopt the various custom circuit modules of prior art to get final product with upper module.
When concrete the application, the method for the utility model is carried out according to following steps:
The first step, pick-up unit comes the control operation to detonator body control module through the form of instruction, sends to detonator earlier and searches the detonator instruction, and detonator is received after this instruction the address of this detonator and defer time to the pick-up unit loopback and be in the reception command status.
Second step; After pick-up unit receives detonator address and defer time information; The inner control module of pick-up unit is opened the low-voltage path and is continued power supply to electric detonator; Because the craftsmenship of the design of the electronic circuit on the detonator, electric capacity keeps a period of time getting into the reception command status again after (500ms) with the low pressure of pick-up unit output.(it is to let the electric capacity on the electric detonator be stabilized in a plateau that the device output voltage keeps the purpose of a period of time.）
In the 3rd step, pick-up unit sends the instruction of opening electronic switch to the control module of detonator, and control module is opened electronic switch after receiving this instruction, makes one to be lower than the detonate electric current of voltage of electric detonator and to flow through the medicine head.Because voltage is lower than the voltage that detonates of electric detonator, therefore, can not cause the blast of medicine head when electric current flows through the medicine head.The interior medicine head of a period of time that electric current flows through the medicine head is equivalent to a resistance, thereby forms pressure drop, utilizes this pressure drop and reference voltage relatively to determine welding quality.If do not welded the medicine head, then there is not electric current to flow through the bridge silk, then the bridge silk is equivalent to infinitely great resistance, the comparator circuit output 0V of this moment; If failure welding, then the comparator circuit output voltage is in 0V and alternately output of VDD; When welding was all right, then the voltage of comparator circuit output was VDD.
