Anti-collision alarming device for car reversing

Abstract

The invention discloses an anti-collision alarming device for car reversing. The anti-collision alarming device comprises a control module, an ultrasonic ranging module, an amplifying circuit, a drive circuit, a brake, a display module, an alarming indicating module and a temperature sensor for collecting atmosphere temperature signals. The ultrasonic ranging module is connected to the input end of the control module through the amplifying circuit. The output end of the control unit is connected with the brake through the drive circuit. The output end of the control module is respectively connected with the input ends of the display module, the alarming indicating module and the temperature sensor. The anti-collision alarming device has the advantages that the device is simple in structure, low in cost, convenient to operate and easy to implement; by the complementation of the ultrasonic ranging module and the temperature sensor, temperature's influence on measuring precision during car reversing is avoided effectively; by the display module and the alarming indicating module, the distance between a car tail and a barrier can be mastered precisely during car reversing.

Description

technical field [0001] The invention relates to an automobile reversing anti-collision alarm device. Background technique [0002] With the development of social economy and the improvement of people's living standards, the number of car ownership has increased significantly. With more and more people owning private cars, there will be more and more traffic problems, which makes the roads and parking lots very crowded, and the driver's field of vision is very limited. occur. Bring serious losses to yourself, and may also cause unnecessary quarrels. As a means of transportation, automobiles have been rapidly integrated into people's lives. However, while bringing the gospel to people, it also brings some troubles. [0003] At present, because the driver reverses the car without seeing the obstacles behind or accurately estimating the distance to the obstacles, it is too late to brake or stop when the obstacles are found, which leads to traffic accidents and disputes. In ...

AI Technical Summary

Problems solved by technology

Because the car has a certain length, width and other factors, the driver cannot observe the situation near the rear of the car from the rearview mirror when reversing, and may accidentally bump into other objects, causing unnecessary losses

Although some existing patents also have ultrasonic radar reversing anti-collision devices, they do not take into account the difference in the speed of sound in the air at different temperatures, making the measurement accuracy not high
