Abstract
The present invention discloses a CO alarm for a super capacitance type generator, comprising a MCU control unit U1, a communication unit U2, a voltage reference unit U3, a system power supply unit U4, an alarm indication unit U5, an engine operation detection unit U6, a CO sensor detection unit U7, a super-capacitor charging unit U8, a temperature detection unit U9, and a flameout control unit U10. The MCU control unit U1 is configured to analyze and process the signal of the entire alarm and control the corresponding actions, and includes a single-chip microcomputer IC1 and a capacitor C1. The capacitor C1 is a filter capacitor, which filters the power supply voltage of the single-chip microcomputer IC1.
