CAN (controller area network)-bus-based intelligent locking system

Abstract

The invention relates to an intelligent locking system, in particular to a CAN (controller area network)-bus-based intelligent locking system, which comprises an intelligent locking ECU (electronic control unit), an intelligent key, an intelligent locking signal receiver and a CAN bus, wherein the intelligent locking ECU is connected with the intelligent locking signal receiver, and is connected with an intelligent switch and an automobile EMS (engine management system) through the CAN bus; if the intelligent locking signal receiver cannot sense the intelligent key after an owner leaves a vehicle for more than 2 meters, the intelligent locking ECU can control the automobile EMS to lock an engine, and controls the intelligent switch to lock vehicle doors through the CAN bus. The CAN-bus-based intelligent locking system has the beneficial effects that the engine can be automatically stopped, and the doors can be automatically locked after the owner leaves the vehicle for a distance beyond a set range, so that the system has antitheft and anti-snatching functions, and key-free control over the flameout of the automobile engine and remote control over the locking of the vehicle doors can be realized.

Description

technical field [0001] The invention relates to an automobile locking system, in particular to an intelligent locking system based on CAN bus. Background technique [0002] Cars are a means of transportation. With the improvement of people's living standards and the reduction of the cost of car manufacturing, more and more people can use cars as a means of transportation, so the proportion of cars is very high. Despite their relative reduction in price, cars are still high-value appliances that are targeted by robbery and theft gangs. In order to prevent robbery and theft of cars, various anti-theft devices have been installed and produced in the automobile production industry. The most common one is the car door remote control anti-theft device. This is the most primitive anti-theft device, but it has simple structure, complicated wiring and scattered data transmission. There are also some locking systems that control the car engine through the central processing unit, and...

Although cars are relatively cheap, they are still high-value appliances and are the target of robbery and theft gangs

In order to prevent robbery and theft of cars, various anti-theft devices have been installed and produced in the automobile production industry. The most common one is the car door remote control anti-theft device. This is the most primitive anti-theft device, but it has simple structure, complicated wiring and scattered data transmission. There are also some locking systems that control the car engine through the central processing unit, and use the remote control to control the ignition engine of the car, but the transmission and reception of the signal are easily affected, there will be some errors in use, and the structure is complicated

Therefore, it is not smart enough in terms of anti-theft and anti-robbery
