摘要
传统的油量检测仪受油量传感器的限制提示效果较差,为此设计了一款汽车油量监测报警器,采用AT89S52单片机为核心,利用超声波传感器实时测量油量高度,通过温度检测模块实时检测油缸温度,利用温度值对超声波传播速度进行数值修正以提高测量精度,最后通过微处理器计算出当前油量值并将其显示在液晶屏上,将当前油量值与设置的阈值进行比较,发出相应的指示信号。该系统控制简单,运行可靠,可实时跟踪汽车油量的剩余量。经过测试结果表明,该系统实现了对汽车油量的监测和报警,测试性能良好。
The display of oil volume of traditional oil meter is limited since the oil quantity sensor and the hint are not ideal,hence an automobile oil monitor alarm is designed in this paper.The AT89S52 single chip computer is used as the control chip.The ultrasonic sensor is used to measure the oil height in real time.The temperature of the oil cylinder is detected in real-time by the temperature detection module.The temperature value is used to modify the ultrasonic propagation velocity in order to improve the measurement accuracy.Finally,the current oil quantity is calculated by microprocessor and displayed on LCD.The current oil quantity value is compared with the set threshold value,and the corresponding indication signal is sent out.The system has the advantages of simple control,reliable operation and real-time tracking of the remaining amount of automobile oil.The test results show that this system can realize monitor the oil of automobile and alarm and the test performance is good.
