An engine anti-theft system based on infrared technology

Abstract

The invention provides an engine anti-theft system based on an infrared technology. The engine anti-theft system comprises a key and am engine lock, wherein an infrared signal emitting circuit and an infrared signal emitting end are arranged on a key handle; an infrared signal receiving end is arranged on the engine lock; the infrared signal receiving end is connected with an engine ECU (electronic control unit); and when the key is in an open state, the infrared signal emitting circuit works after being electrically connected with the engine ECU, the infrared signal emitting end emits an infrared signal to the infrared signal receiving end, and the engine ECU controls an engine ECU body to perform an engine management program according to the infrared signal. By adopting the system, the infrared technology is applied innovatively to the motorcycle anti-theft field under the promise that the using security of a system power supply is ensured and the communication is reliable; by combining the characteristic that an electronic-injection motorcycle has an engine management control unit and through designing by using a cheap infrared emitting and receiving diode, the engine anti-theft of the motorcycle is achieved, and therefore the motorcycle engine anti-theft cost is reduced.

Description

technical field [0001] The invention relates to the technical field of engine anti-theft, in particular to an engine anti-theft system which utilizes infrared technology to transmit signals to realize anti-theft. Background technique [0002] Engine anti-theft is currently the most popular anti-theft solution, but it is expensive and only used on some cars, and rarely used on motorcycles. [0003] The working principle of a typical engine anti-theft system is: the ignition key of the vehicle is equipped with an electronic chip, each chip is equipped with a fixed ID (equivalent to an identification number), only the ID of the key chip is consistent with the ID on the engine side On the contrary, if it is inconsistent, the car will automatically cut off the circuit immediately, so that the engine cannot be started. This anti-theft method needs to install electronic chips on the ignition key and the engine, and the cost is relatively high. Contents of the invention [0004] ...
