Double anti-theft alarming method for automobile

Abstract

The invention relates to an automobile double burglar alarm method. The method comprises the following steps: when in protecting, firstly, a key is turned to the position of OFF, a central processing unit is used for making a judgment and an MCU gives out locking command to an engine after the set time interval, and the first protection is finished; the key is pull out, the door is closed, a remote controller emits fortifying command, a wireless receiving module of a host in the automobile receives the command, the MCU gives out action command to all the circuits and gives out locking commandto the engine again, and the second protection is finished; when in out of protection; the first deprotection is carried out by the remote controller; then the door is opened, a driver enters the automobile and uses an identification sensing chip to approach a receiving antenna of the sensing module in the hidden place; the receiving antenna transmits an identification sensing signal to the sensing module, then comparison is carried out by the MCU and gives out the engine unlocking command after the identification is confirmed, and the second protection is finished. The invention has the anti-theft function by remote control emission and the chip simultaneously, thus leading the anti-theft safety to be greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of automobile anti-theft alarms, in particular to a double anti-theft alarm method for automobiles. Background technique: [0002] At present, there are many anti-theft technologies and products for automobiles. There are traditional manual anti-theft methods, such as adding some mechanical equipment to lock the brakes or use the clutch principle to prevent the vehicle from moving, or to cut off the fuel supply circuit and ignition circuit by modifying the circuit and installing a dark switch. Prevent the engine from starting, etc., so as to achieve the purpose of anti-theft; in addition, there are high-tech anti-theft, such as using GSM network or GPS technology to realize real-time monitoring of the vehicle or using wireless technology to arm and disarm the vehicle through the remote controller.

Problems solved by technology

[0002] At present, there are many anti-theft technologies and products for automobiles. There are traditional manual anti-theft methods, such as adding some mechanical equipment to lock the brakes or use the clutch principle to prevent the vehicle from moving, or to cut off the oil supply circuit and ignition circuit by modifying the circuit and installing a hidden switch. Prevent the engine from starting, etc., so as to achieve the purpose of anti-theft; in addition, there are high-tech anti-theft, such as using GSM network or GPS technology to realize real-time monitoring of the vehicle or using wireless technology to arm and disarm the vehicle through the remote controller. Fingerprint identification or a special key with transmitting and receiving functions for the preparation institute, the key head enters the oil and circuit control of the vehicle through the ignition switch, the above methods seem to be very feasible for laymen, but for those who know little about car maintenance and have some For thieves of illegal high-tech products, it is really easy to crack the above anti-theft, so any single anti-theft method is not safe and reliable enough
