The invention discloses an automatic anti-theft alarm system for an oil tank. The automatic anti-theft alarm system is composed of a normal operation state and an early warning state. The operation process of the early warning state is as follows: the vehicle is locked, the whole vehicle is powered off, a change-over switch is turned on, and the early warning system starts to work; a floater position signal when the early warning system is opened is used as a basic comparison signal; a floater position signal is read timely and compared with a system initial value, and when the floater position signal exceeds a preset difference value, an alarm is triggered; the difference value preset range needs to consider an environment temperature factor; the system shares a vehicle-mounted power supply and has a power failure alarm function. According to the automatic anti-theft alarm system for the oil tank, the alarm is triggered by monitoring the change rate of the floater, an alarm can be given when the change rate of the floater is abnormal, the system completely depends on an original vehicle line, only the alarm module needs to be additionally loaded, and more convenience is achieved.

    本发明公开了一种油箱自动防盗报警系统,所述自动防盗报警系统由正常运行状态和预警状态组成;所述预警状态的运行过程如下:锁车、整车断电、打开转换开关,预警系统开始工作;预警系统打开时的浮子位置信号,作为基础对比信号;适时读取浮子位置信号,并与系统初始值做对比,当超过预设差值时,即触发报警;差值预设范围需考虑环境温度因素;系统共用车载电源,并设断电报警功能。该油箱自动防盗报警系统,通过监控浮子的变化率,来触发报警器,在浮子变化率发生异常时即可报警,而且此系统完全依靠原车线路,只需另外加载报警模块即可,更加便捷。
