Abstract
This invention discloses a multi-delay mode delay pulse generation circuit, including a signal input unit, a signal processing unit, a pulse generation unit, and a pulse output unit. In the signal input unit, a logic processing circuit receives a level combination signal and a control pulse signal, and multiple signal output circuits are configured according to their combination. Each signal output circuit is connected to a delay selection circuit. In each delay selection circuit, a delay control signal is used to control the state of the delay selection switch, so that the signal delay processing circuit processes the signal output from the signal output circuit into a pulse signal DLY with a corresponding delay, which is then sent to the pulse generation unit. The pulse generation unit generates a detonation pulse based on the pulse signals DLY output from the multiple delay selection circuits. The pulse output unit outputs the detonation pulse to the detonation driving device. This invention enables the selection and setting of the delay of the driving pulse to provide pulse signals with different delays as needed, achieving precise control of the load switching time.
