The invention discloses a built-in CO monitoring and alarming device for a fuel vehicle, which comprises an energy complementing and storing module, a negative half-cycle chopping type flameout module, a voltage stabilizing module, a CO sensor module and the like, the MCU is electrically connected with the state indication and alarm module, the shutdown signal input module, the temperature measurement module, the pulse synchronization module and the power supply voltage measurement module, obtains the pulse state of the magnetor through the pulse synchronization module, judges whether the current engine is started or not, and starts to process and analyze data of the CO sensor module if the engine is started; when the CO concentration is close to the dangerous concentration, the state indication and alarm module is controlled to start to remind a user, and if the CO concentration reaches the dangerous concentration, a synchronous flameout program is started. The CO monitoring alarm device utilizes the flameout line of the engine to supply power to the CO alarm device, does not need external power supply support, and solves the problem of high power consumption of the existing CO alarm device.
本发明公开了一种燃油车内置CO监测报警装置,包括:能量补集和储能模块、负半周斩波式熄火模块、稳压模块、CO传感器模块等,MCU为装置整体中的微控制器,MCU与状态指示及报警模块、停机信号输入模块、温度测量模块、脉冲同步模块和电源电压测量模块电连接,MCU通过脉冲同步模块获取磁电机脉冲状态,判断当前发动机是否启动,若发动机启动,则开始对CO传感器模块的数据进行处理分析,CO浓度接近危险浓度状态下,控制状态指示及报警模块启动提醒用户,若CO浓度已达到危险浓度,则进入同步熄火程序。本CO监测报警装置利用发动机的熄火线给CO报警装置供电,无需外部电源支持,解决了现有一氧化碳报警装置功耗高的问题。
