摘要
为了确保LNG动力汽车的安全稳定运行,提出一种基于GPRS无线传输的车载LNG气瓶监测系统。该系统以STC51单片机为主控芯片,主要设计甲烷浓度采集电路、温度采集电路、LCD显示电路、蜂鸣器报警电路、GPRS无线通信电路等,可把测量的数据通过GPRS网络发送到服务器中,最后将传输的数据在LabVIEW平台上处理后显示,实现气瓶安全的在线监测。实验结果表明,该系统可准确地检测甲烷浓度值及罐体与环境温差,在不良状况时能及时有效地报警,达到实时预警的目的。
A vehicle LNG cylinder monitoring system based on GPRS wireless transmission is proposed to ensure the safe and stable operation of LNG hybrid electrical vehicle. In this system,the STC51 single-chip microcomputer is used as the main control chip,and the methane concentration acquisition circuit,temperature acquisition circuit,LCD display circuit,buzzer alarm circuit,GPRS wireless communication circuit and so on are designed mainly,which can send the measured data to the server through GPRS network. The transmitted data is displayed after processing on the LabVIEW platform to realize the on-line monitoring of cylinder safety. The experimental results show that the system can accurately detect the methane concentration value and the temperature difference between the tank and the environment,and can give an alarm timely and effectively in the bad conditions,so as to achieve the purpose of real-time warning.
