A parking braking state monitoring system with a warning function comprises a single-chip microcomputer, a power circuit, a parking state signal detection circuit, an ignition switch state signal detection circuit, a driving side vehicle door state signal detection circuit, a Bluetooth module, a single-chip microcomputer downloader, a crystal oscillator circuit and a filter circuit. When the single-chip microcomputer receives that a zhuche_out signal sent by the parking state signal detection circuit is 5V (parking braking is not applied), a dianhuo_out signal sent by the ignition switch state signal detection circuit is 0 V (an ignition switch is turned off), and a jiashimen_out signal sent by the driving side vehicle door state signal detection circuit is 0 V (a driver side vehicle door is opened), the single chip microcomputer judges that the driver gets off or prepares to get off but forgets to apply parking braking to the vehicle, and controls the Bluetooth module to send a signal to a mobile phone for reminding. According to the invention, secondary accidents can be effectively prevented, the system function is clear, the judgment on the parking state of the automobile is accurate, the cost is low, and the parking is safer and more guaranteed.
一种带警示功能的驻车制动状态监测系统,包括单片机,电源电路,驻车状态信号检测电路,点火开关状态信号检测电路,驾驶侧车门状态信号检测电路,蓝牙模块,单片机下载器,晶振电路和滤波电路,当单片机在接收到驻车状态信号检测电路发出的zhuche_out信号为5V(未施加驻车制动)且点火开关状态信号检测电路发出的dianhuo_out信号为0V(点火开关已关闭)且驾驶侧车门状态信号检测电路发出的jiashimen_out信号为0V(驾驶员侧车门已打开)时,单片机则判断为驾驶员已下车或准备下车但忘记对车辆施加驻车制动,控制蓝牙模块发送信号到手机进行提醒。本发明可有效防止次生事故的发生,系统功能明确,对汽车驻车状态的判断准确,成本低廉,停车更安全、更有保障。
