The invention discloses a vehicle door opening early warning system. The system comprises a single-chip microcomputer controller, an information processing device, an ultrasonic transmitting circuit, an ultrasonic receiving circuit, a sound alarm, an LED display screen, a control circuit power source and a vehicle door locking device. A first probe and a second probe are installed on the outer side of a vehicle door, and two 16-bit timers are arranged in the single-chip microcomputer controller. The initial value of the timers is 0, after the timers are started, one is added to the timers every one microsecond, the timers are started when the ultrasonic transmitting circuit transmits ultrasonic waves, the timers are closed when the ultrasonic receiving circuit receives the ultrasonic waves, the numerical values of the timers are the time when the ultrasonic waves go back and forth, and the single-chip microcomputer controller measures the distance twice through the ultrasonic waves to obtain the time Tp from an object to the vehicle door. According to the numerical values of the Tp, the sound alarm, the LED display screen and the vehicle door locking device are controlled to be opened. Compared with the prior art, the system has the advantages that the vehicle parking condition can be monitored, and the system has the characteristics of low cost and low power consumption.
本发明公开了一种车门开门预警系统，包括单片机控制器、信息处理装置、超声波发射电路、超声波接收电路、声音报警器、LED显示屏、控制电路电源和车门上锁装置，车门外侧安装探头一和探头二，所述的单片机控制器内部设有两个16位定时器，定位器初始值为0，启动定时器后每隔1微秒定时器加1，超声波发射电路发射超声波时定时器启动，超声波接收电路接收超声波时定时器关闭，定时器的数值是超声波来回的时间，单片机控制器通过超声波两次测距，得出物体到车门的时间Tp，根据Tp的数值控制声音报警器、LED显示屏和车门上锁装置的开启。本发明与现有技术相比的优点在于：不仅能够实现监控汽车驻车情况，还具有成本低，耗电少的特点。
