Electric vehicle anti-theft system control method

Abstract

The invention discloses an electric vehicle anti-theft system control method. The electric vehicle anti-theft system control method mainly comprises the steps that whether a protection key on a remote control unit is pressed down or not is judged, and if yes, a system enters a protection state; a vibration sensing unit judges whether vibration exists or not outside, if yes, the vibration sensing unit generates vibration feedback, and a feedback signal is transmitted to an alarming circuit and transmitted to a sound and light alarm circuit on the remote control unit in a wireless data transmission mode; when the time reaches the set value of a clock circuit, an alarm is stopped, and the protection state is reset; and whether a protection withdrawing key on the remote control unit is pressed down or not is judged, and if yes, a relay is powered off and a main circuit is connected. The defects that the trigger point is simplex, autonomous defense cannot be achieved after a vibration sensor is damaged and information of an electric vehicle cannot be synchronized to an owner in the wireless remote control type anti-theft mode in the wireless anti-theft process in the prior art are overcome, so that an anti-theft vibration sensing circuit is more reliable, sensitive and efficient, and the bidirectional alarm function of the electric vehicle is achieved.

Description

technical field [0001] The invention relates to the field of anti-theft technology, in particular to a control method for an anti-theft system of an electric vehicle. Background technique [0002] With the development of industry, traditional energy sources are shrinking, and resources are unsustainable. Most of the energy closely related to daily life like oil comes from imports and is easily affected by external factors. For example, the second Iraq war made the global oil supply tense, and OPEC kept raising the price of crude oil in order to protect its own interests. Moreover, our country's oil reserves are not large, so the oil price fluctuates severely, and the five-yuan era quickly returned to the six-yuan era after only a few days. Coupled with the proposal of the national sustainable development strategy and the improvement of environmental protection awareness, electric vehicles came into being in such a market environment. It uses renewable energy electric energ...

Problems solved by technology

Because the one-time cost of installing GPS, GSM, and GPRS is much higher than other anti-theft methods, and users are required to pay follow-up service fees, this makes most electric vehicle owners unwilling to accept it and cannot be widely used, so they are in the electric vehicle market. less promising

[0007] In the process of realizing the present invention, the inventor found that in the prior art at least most electric vehicle users still use anti-theft devices such as mechanical anti-theft and one-way anti-theft mode, which cannot effectively ensure the safety of electric vehicles. At the same time, electric vehicles In the design of anti-theft, the vibration sensing module of the electric vehicle is easily triggered to cause false alarms. At the same time, in the design of wireless anti-theft, the wireless remote control anti-theft cannot synchronize the information of the electric vehicle to the owner and other defects.
