Detonating control circuit of time delay

The utility model discloses a detonating control circuit of time delay, including a charging circuit, a discharge circuit, a protection circuit and a functional circuit. Charging circuit includes a energy storage device for carry out the energy storage after receiving the current signal, the discharge circuit includes a switch circuit who is used for connecting the electric cap, and when a switch circuit switches on, during the electric cap is released via a switch circuit to the energy of storage in energy storage device, realizes that remote control ignites instant electric detonator, the functional circuit includes a programming device, through the programming device can set up a switch circuit's time delay turn -on time in a flexible way, and the time delay precision is higher, in addition, the protection circuit still includes one the 2nd switch circuit, and when a switch circuit was in off -state, the 2nd switch circuit switched on, and the energy of storing in energy storage device is released via the 2nd switch circuit, and the electric cap can not be by the spurious triggering when off -state effectively to have guaranteed a switch circuit.
