Automobile acceleration monitor anti-theft warning system

Abstract

The car acceleration supervision and guard against theft and alarm system includes the sensor of the wheel state within the wheel, the sound-light annunciator within the bodywork. The sensor of the wheel state within the wheel comprises of the acceleration sensor, the first microprocessor which is linked with the fan-out of acceleration sensor and the first module of radio frequency launch which is linked with the input of the first microprocessor. The vehicle guard against theft and alarm system comprises of the second microprocessor, the second module of radio frequency launch which is linked with the input of the second microprocessor, the module of orientation and communication of the vehicle, the holding terminal. The sensor of the wheel state and the system of guard against theft and alarm of vehicle forming the system can check the non-normal movement of the vehicle by wireless dispatcher. The combination of the system of guard against theft and alarm of the vehicle and the module of orientation and communication of the vehicle can form the system that can supervise the non-normal movement of the vehicle. The alarming modes have the wireless warning, vehicle orientation tracing and long-distance control in addition to the traditional sound-light warning, which insure the alarming valid in time.

Description

technical field [0001] The invention relates to a car anti-theft alarm system, in particular to a monitoring and alarm system for detecting changes in the speed of a car, judging whether it is stolen, and monitoring the whereabouts of the stolen car. Background technique [0002] Cars are an important means of transportation in modern life, and car alarms are necessary electronic devices. Traditional car anti-theft devices are mostly based on mechanical vibration detection. It consists of a mass block, spring, transmission link, toggle switch, etc. The detection device is composed of a mass block. When the vehicle moves, the mass block will move and move through the spring belt to the transmission link to start Toggle the switch to activate the alarm device. The detection sensitivity of this system is not easy to adjust. If the sensitivity is too high, false alarms may be generated due to the interference of unexpected vibrations; if the sensitivity is too low, it is diffic...

Problems solved by technology

This kind of device also has the problem that the detection sensitivity is not easy to adjust, and the sensitivity is too high. For example, if the inclination level is set to 5 degrees as the alarm limit, it is very easy to cause false alarms due to climbing and crossing the bridge. Abnormal vibration of the vehicle body is inevitable, such as bridge crossing vibration. Or thunder and vibration, etc., the noise pollution caused by frequent false alarms is not allowed by environmental protection, so the gravity acceleration detection method may not be able to be promoted in our country
