Abstract
This invention relates to the field of fire detection technology and proposes a fire detection system, including a fire detection circuit. The fire detection circuit includes a resistor R1, a diode D1, a capacitor C2, a transformer T1, a transistor Q1, a diode D2, and an ultraviolet detector U1. The first end of resistor R1 is connected to the VCC power supply, and the second end of resistor R1 is connected to the base of transistor Q1. The collector of transistor Q1 is connected to the first input terminal of transformer T1, and the collector of transistor Q1 is connected to the anode of diode D2. The cathode of diode D2 is connected to the first power supply terminal of ultraviolet detector U1, and the second power supply terminal of ultraviolet detector U1 is connected to the second input terminal of transformer T1. The output terminal of ultraviolet detector U1 is connected to the main control unit. The first output terminal of transformer T1 is connected to the base of transistor Q1 through capacitor C2, the cathode of diode D1 is connected to the base of transistor Q1, and the anode of diode D1 is grounded. However, this technical solution suffers from poor accuracy in the fire detection system.
