Description

A method for preventing theft of vehicle oil

technical field

The invention relates to a vehicle fuel anti-theft method, in particular to a vehicle fuel anti-theft method based on a radio frequency combined with an acceleration sensor.

Background technique

Now vehicles as a means of transportation have been widely used in people's production and living activities. As far as the currently commonly used vehicles are concerned, most of them use fuel combustion as their power source. When implementing them, At present, many high-fuel consumption models such as trucks, buses, and oil trucks often need to carry out long-distance transportation, so these vehicles will be equipped with larger fuel storage tanks to support their long-distance transportation, and this The fuel storage tank of this type of vehicle is generally filled with fuel habitually.

Driven by the increasing fuel prices, there are now some criminals of all kinds using various means to steal fuel to seek illegal benefits. Such thieves generally include professional criminals and fuel truck drivers.

At present, the common way to steal oil is to pry open the fuel tank to directly pump oil to steal oil. In order to prevent this kind of theft, the general solution is to directly replace the anti-theft fuel tank cap, but for some models, there is no corresponding anti-theft fuel tank on the market. For the configuration of the cover, another anti-theft method is to add a welded oblique steel mesh at the oil inlet of the fuel storage tank, which can prevent the large oil pipe from stealing oil, but it does not have the anti-theft function for the thin pipe to steal oil.

The latest anti-theft methods include installing infrared sensors on the fuel tank cap to prevent oil stealing. However, when this method is implemented, due to the sensitivity of infrared sensors, it is easy to misread after long-term use, so the anti-theft The effect is not ideal.

To sum up the above, the existing anti-theft method is mainly by adding a ring-mounted conical anti-stealing oil net at the oil inlet of the fuel storage tank of the fuel-consuming vehicle or replacing a new fuel tank cap with anti-theft function or adding an infrared sensor at the opening of the fuel storage tank. The purpose of stealing oil is achieved by means of sensors to detect foreign objects. At present, these anti-theft methods have reduced to a certain extent the probability that the fuel in the fuel storage tank of the fuel-consuming vehicle is stolen by criminals when the driver or the owner is not far away from the vehicle, but they cannot solve the problem of eating, resting, parking, etc. during long-distance transportation. Lawless person or the problem that vehicle employs driver etc. steals fuel oil, and this is the main shortcoming of prior art.
