Abstract

This invention provides a full-function fire pump charging angle ignition controller, comprising a housing and an internal circuit board. The circuit board integrates a control unit and an ignition module. The control unit includes a microcontroller and a trigger circuit. The trigger circuit includes a voltage-regulating and current-limiting circuit, a positive trigger signal input circuit, and a negative trigger signal input circuit. The input terminal of the voltage-regulating and current-limiting circuit receives the trigger signal, and its output terminal is connected to the input terminals of the positive and negative trigger signal input circuits. The output terminals of the positive and negative trigger signal input circuits are respectively connected to the positive and negative signal input pins of the microcontroller. The ignition module includes an ignition drive circuit, whose input terminal is connected to the microcontroller's signal output pin, and whose output terminal is connected to the ignition coil input terminal. This invention solves the problem of false triggering caused by various interferences or malfunctions during signal transmission in existing integrated ignition systems.
