Technical Field

The invention relates to the technical field of electronics, in particular to a system for prompting an automobile inward opening door.

Background

In recent years, with the development of science and technology and the improvement of living standard of people, automobiles are rapidly popularized as vehicles. In order to improve the safety of automobiles, more and more technologies are used in automobiles to assist drivers in driving, however, the problem of how to prevent the automobile door from being opened when the automobile door is stopped cannot be solved well, for example, when a passenger opens the door, the door car collides with an outer step of the automobile door or a parked vehicle beside the automobile door, and thus the intellectualization and the vehicle using experience of the automobile are greatly reduced. In the prior art, a red indicator light is arranged on an automobile door to prompt pedestrians or bicycles not to collide with the automobile, but not prompt people who open the automobile door to safely open the door. Therefore, the accidents that the automobile is stopped conveniently and the door is opened conveniently and the passerby, the bicycle and the battery car are knocked down frequently occur. Therefore, a system for prompting the automobile inward opening door becomes a problem to be solved urgently.

Disclosure of Invention

The invention aims to solve the technical problem of a system for prompting an automobile inward opening door.

In order to solve the technical problem, the technical scheme provided by the invention is a system for prompting the inward opening door of an automobile, which comprises the following steps: the device comprises a microcontroller, a pressure sensor, a speed sensing module and a voice alarm module; the microcontroller is arranged in the automobile cab, the pressure sensor is arranged on a buckle in the automobile door, the speed sensing module is arranged on the automobile engine, and the voice alarm module is arranged in the automobile door; the signal output ends of the microcontroller and the pressure sensor are connected to the signal input end of the microcontroller, and the signal input end of the voice alarm module is connected to the signal output end of the microcomputer module.

As an improvement, the speed induction sensor adopts a vibration sensor.

As an improvement, the automobile door control system further comprises an LED arranged on the outer side of the automobile door, and the signal input end of the LED is connected with the signal output end of the microcomputer module.

Compared with the prior art, the invention has the advantages that: the invention can detect the current driving speed, when the current driving speed is zero, the microcontroller unlocks the hidden lock of the vehicle door, when the pressure sensor arranged on the door handle in the vehicle detects the pressure after the user gets off the vehicle, the loudspeaker gives an alarm to the surrounding people according to the preset program, thereby reminding the user and the surrounding people in time when the driver or the passenger opens the door, so as to prevent the vehicle door from being collided, improve the intelligent degree of the vehicle, reduce traffic accidents and ensure the life safety of people.

Detailed Description

The following describes a system for prompting an automobile inward opening door according to the present invention in further detail with reference to the accompanying drawings.

With reference to fig. 1-2, a system for prompting an automobile inward opening door comprises a microcontroller, a pressure sensor, a speed sensing module and a voice alarm module; the microcontroller is arranged in the automobile cab, the pressure sensor is arranged on a buckle in the automobile door, the speed sensing module is arranged on the automobile engine, and the voice alarm module is arranged in the automobile door; the signal output ends of the microcontroller and the pressure sensor are connected to the signal input end of the microcontroller, and the signal input end of the voice alarm module is connected to the signal output end of the microcomputer module.

The speed induction sensor adopts a vibration sensor.

The automobile door signal input end is connected with the signal output end of the microcomputer module.

The specific implementation process of the system for prompting the automobile inward opening door comprises the following steps: when a door opener opens a door, whether the automobile stops running is detected through a vibration sensor arranged on an automobile engine, when the automobile is detected not to stop running completely, a microcontroller does not open a hidden lock of the door, the door cannot be opened by pressing an inner door handle, and the door opener is prompted to stop running through a voice alarm module, the door opener tries to open the door again or for multiple times, and the microcontroller restarts the judgment; when the automobile is detected to be static, the microcontroller opens the built-in lock of the automobile door, the user opens the automobile door, the hand is placed on the buckle of the door in the automobile, the pressure sensor detects the pressure and immediately makes a sound by opening the LED and the voice alarm module to ensure that the door opening person can safely open the door by opening the outer side of the automobile door, and the surrounding people can be prompted.
