Automobile oil sealing and oil leaking intelligent detection and alarm device

Abstract

The invention relates to the field of measurement and control system and diagnosis technology and particularly relates to an automobile oil sealing and oil leaking intelligent detection and alarm device. The device comprises a power module, an automobile start / close state detection module, an oil tank liquid level detection module and an alarm module; and the core works around a single chip. The power module supplies power to the device by use of the automobile battery voltage through a voltage conversion chip. After the automobile start / close state detection module detects that the automobile is in a closed state through automobile switching value detection and CAN bus data detection, the device starts working. The oil tank liquid level detection module sends a liquid level signal to the single chip through automobile fuel quantity sensor detection and CAN bus data detection, and compares the liquid level signal with an initial liquid level signal; and if the liquid level is lowered, the single chip sends an alarm signal to the alarm module. The alarm module realizes a sound-light alarm function and a short message alarm function. The device provided by the invention has the beneficial effect that automatic alarm for oil stealing and oil leaking is realized.

Description

technical field [0001] The invention relates to the technical field of measurement and control systems and diagnosis, in particular to an intelligent detection and alarm device for automobile oil theft and oil leakage. Background technique [0002] As the price of oil continues to soar, stealing and selling oil has become another way for many criminals to make a living. Drilling holes in the fuel tank, prying the fuel tank cap, dismantling the oil suction pipe, dismantling the oil screw, and other methods of stealing fuel have emerged one after another, which makes drivers hard to guard against and headaches. [0003] The common anti-stealing measures on the market are to replace the anti-theft fuel tank cap, screen the fuel tank port, add a protective plate above the oil suction pipe, weld wire or round the oil drain screw, but the anti-theft effect is not good and time-consuming and labor-intensive. If it is not handled properly, not only will it not have the effect of pr...

[0003] The common anti-stealing measures on the market are to replace the anti-theft fuel tank cap, screen the fuel tank port, add a protective plate above the oil suction pipe, weld wire or round the oil drain screw, but the anti-theft effect is not good and time-consuming and labor-intensive

If it is not handled properly, not only will it not have the effect of preventing oil theft, but it may also cause a great safety hazard to the vehicle, especially the driver.
