Abstract

The invention discloses a motor vehicle oil tank oil stealing prevention system that comprises an oil tank and an electric control device; the electric control device is connected with a display screen, the oil tank is provided with an oil filling port, the oil filling port is downwardly connected with an oil filling pipe, the oil filling pipe extends into the oil tank, and a one-way valve is arranged at the bottom end of the oil filling pipe; a push switch is arranged on a grating plate, and the electric control device is connected with a first audible and visual alarm and a second audible and visual alarm. The invention further discloses an alarm control method of the motor vehicle oil tank oil stealing prevention system. The system and method can prevent the oil tank from being deflatedunder the action of a negative pressure, an oil pumping pipe is effectively prevented from being inserted into the oil tank, so the oil stealing phenomenon is more effectively prevented; an alarm canbe given in time when the oil stealing phenomenon occurs, and false alarm is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of motor vehicle anti-stealing oil. Background technique [0002] With the continuous growth of car ownership and the continuous growth of road traffic, motor vehicles have an increasing demand for fuel, and fuel prices continue to rise. More and more lawbreakers are targeting the fuel in motor vehicles. Large-scale transport vehicles have large fuel tanks and a large amount of fuel storage. In recent years, incidents of fuel theft from large transport vehicles have occurred frequently. [0003] Oil thieves use negative pressure to pump oil, and can pump out the whole tank of oil in a short period of time (more than ten seconds) (if the oil in the oil tank is stolen, it will take a long time), the crime time is short, and the driver It is hard to prevent; in order to speed up the speed of committing crimes, oil thieves often use strong negative pressure, and when stealing oil, the fuel tank is deflated unde...
