Detailed Description
The following detailed description of the embodiments according to the present invention, with reference to the accompanying drawings and the embodiments of the present invention, is as follows:
as shown in fig. 6, the control circuit includes a wireless communication circuit, a CPU, a DC-DC power module, a charge and discharge function control circuit, a detonation function control circuit, and a self-destruction function control circuit; the wireless communication circuit receives the wireless control signal and transmits the wireless control signal to the CPU for processing, and sends out a corresponding control instruction through internal signal detection.
(1) FIG. 1 shows a 12V/12V isolated power supply. When the system is connected with a power supply, the isolation power supply generates a stable voltage of +12V, and the U1 is an isolation device, so that the influence of static electricity, stray current and radio frequency current on a subsequent control circuit can be well inhibited, and the purpose of protecting an internal electronic circuit is achieved. The TS1 device is a transient suppression diode, and when it is interfered by high energy pulse, the internal working impedance will change, and further reduce the conduction value, absorb large current to clamp the two ends of the voltage at the predetermined level,

(4) Fig. 4 shows a charging/discharging/detonation function control circuit: the charging control signal output by the singlechip is connected with a diode D1, and the cathode of the diode is grounded through an energy storage capacitor C12; the 'safe' control signal output by the singlechip is connected with a diode D2 and then is grounded through a capacitor C13, the cathode of the diode is simultaneously connected with the grid of an N-channel field effect transistor Q1, the source of Q1 is connected with an energy storage capacitor C12, and the drain of Q1 is connected with a resistor R1; the 'detonation' control signal output by the single chip microcomputer is connected with a diode D3 and then grounded through a capacitor C14, the cathode of the diode is connected with the grid of an N-channel field effect transistor Q2, the drain of the Q2 is connected with a diode D1 and then connected with a 'charging' control signal end of the single chip microcomputer, and the source of the Q2 is grounded through a bridge wire resistor R2.
When the CPU receives the charging signal, the system power supply voltage charges the energy storage capacitor C12 through D1, and energy storage preparation is made for subsequent electronic detonator detonation. In a charging state, if the electronic detonator is not required to be detonated for special reasons, the voltage of the energy storage capacitor needs to be released, and a 'safety' instruction needs to be given at the moment. When the CPU receives a 'safe' instruction, the N-channel field effect transistor Q1 is conducted, the energy storage capacitor and the resistor R1 form a discharging loop, the circuit is in a discharging safe state, and the electronic detonator cannot detonate. When the CPU receives a detonation command, the N-channel field effect transistor Q2 is conducted, the energy stored by the energy storage capacitor is discharged through the bridge wire resistor R2 of the electronic detonator, the bridge wire resistor is generally 1-5 omega, the discharge current is large, and the electric energy is converted into heat energy to detonate the detonator, so that the detonation operation is completed.

After the CPU receives the self-destruction instruction, the N-channel field effect transistor Q3 is conducted, the system power supply is instantly connected through the fuse, the fuse is directly burned out by large current, the system power supply voltage is cut off, the CPU cannot work, and the safety of the electronic detonator is further ensured.
The 'safety' and 'detonation' instructions are sent in a delayed manner after the 'detonation' instruction is sent in a circuit charging state, and the purpose is to release the voltage of an energy storage capacitor and ensure that an electronic detonator which cannot be detonated loses the detonation capability. All time sequence control is completed by the CPU, and the purpose of accurately controlling the electronic detonator in a delayed manner is achieved.
