Intelligent monitoring and over-limit alarm device for gas tank

The utility model provides a gas tank intelligence monitoring and overrun alarm device, including gas tank, PLC controller, sensor group and alarm mechanism, sensor group includes liquid level sensor, temperature sensor and pressure sensor, alarm mechanism includes buzzer and indicating lamp, indicating lamp can give out light of three different colors, and the alarm mechanism includes the buzzer and indicating lamp. The liquid level sensor, the temperature sensor and the pressure sensor are arranged in the gas tank and can collect liquid level information, temperature information and pressure information in the gas tank, corresponding threshold data are stored in the PLC, and when the liquid level, the temperature or the pressure exceeds the threshold data, the PLC can control the buzzer to give an alarm, so that the gas tank is protected. And the indicating lamp is correspondingly controlled to generate light with a corresponding color so as to remind a worker of data abnormity of the current gas tank, so t
