Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages in the prior art that only a single transmission signal exists between the remote control transmitting device and the receiving and executing device, which is difficult to balance the anti-theft security and the convenience of operation, and the password of the anti-theft system can be set by the user himself Set and change at will to make it more humanized and further improve the anti-theft performance

Abstract

An antitheft system controlled by both radio and infrared and able to set up code by user itself for car is composed of a remote-control emitter consisting of key input device, the first microprocessor and signal output device, and a receiving-executing device consisting of signal receiver, the second microprocessor, driver, relay and executing circuit. Said signal output device has radio emitting module and infrared emitting module. Said signal receiver has monitor signal input device, radio receiving module and infrared receiving module.

Description

【Technical field】 [0001] The invention relates to an automobile anti-theft system, in particular to a photoelectric dual-control self-coded automobile anti-theft system. 【Background technique】 [0002] Existing one-way car anti-theft device is generally made up of remote control transmitter and receiving actuator, and the connection mode between the two all adopts single transmission signal, as single wireless signal or single infrared signal, and these two kinds of signals have respective advantages. shortcoming. The advantage of the wireless signal is that the transmission distance is long, and it is non-directional and easy to operate, but it has the disadvantage that the password information in the radio wave is easily intercepted and deciphered by the electronic decoder hidden on the thief due to its strong penetration. The advantage of the infrared signal is that it has strong directionality and poor penetration. Therefore, the code information attached to the light w...
