Description
Technical Field
The utility model relates to an automobile anti-theft safety field specifically indicates a vehicle oil tank anti-theft device.
Background
In recent years, the case of fuel tank theft of trucks frequently occurs, and truck driver groups urgently need an anti-theft device to protect own property;
the parking environment of a large truck is generally complex and is mostly a noisy environment with multiple rows of vehicles and dense people, and a common anti-theft device is easily affected by the influence and cannot well judge whether a trigger signal is generated by theft; according to data analysis, lawless persons steal oil, and multi-purpose electric drills, cutting machines and the like violently open holes in an oil tank so as to steal fuel oil, the mode of stealing makes the traditional mechanical passive anti-theft device lose the security and anti-theft effect, and the electronic anti-theft alarm is mainly used for active anti-theft, so that the security and anti-theft effect can be well played. Before a lawbreaker steals the fuel tank, the fuel tank is knocked for a plurality of times so as to estimate the residual fuel quantity of the fuel tank and determine a theft target. According to the characteristic, the anti-theft device is provided with a vibration frequency induction device for identifying the vibration frequency signal, and sets the high vibration frequency generated on the oil tank by the tapping probe before the burglary occurs, which is obtained through multiple experimental investigations and accords with the tapping probe before the burglary occurs, as a preset vibration frequency threshold value.
People also design various counter measures aiming at the theft behavior, and the main anti-theft technologies on the market comprise the following technologies;
the vibration sensing burglar alarm uses a vibration sensor to trigger the sensor when vibration occurs, and due to the fact that the sensitivity of the vibration sensor is high, alarm can be triggered when the vibration sensor slightly vibrates, the sensor cannot identify the type of a vibration signal, and the false alarm rate is high.
The infrared induction burglar alarm is easily interfered by various heat sources and sunlight sources. The infrared penetration force is poor, and the infrared radiation of a human body is easily shielded and is not easily received by a detector. Susceptible to interference from radio frequency radiation. When the environment temperature is close to the human body temperature, the detection and sensitivity are obviously reduced, and short-time failure is sometimes caused;
the liquid level sensing burglar alarm is used for alarming when the liquid level sensor senses that the liquid level rapidly drops, although the false alarm rate is low, the alarm is triggered after fuel oil is stolen, the passive design cannot prevent burglary in the bud, the alarm is not timely, and the benefits of drivers and friends are lost;
the burglar alarm combining the radar sensor and the vibration sensor is added with a judgment mechanism, so that a certain false alarm rate is reduced, but the radar sensor cannot distinguish the type of an invading object, and can be easily interfered by foreign matters as long as moving objects can trigger. The vibration sensor can be triggered by a slight vibration signal, the type of the vibration signal cannot be identified, the burglar alarm cannot identify whether the triggering is caused by theft, and the system still has high false alarm rate.
From the above, although a series of anti-theft measures are designed for the theft of the fuel tank in the prior art, the effect is not particularly ideal.
