[0002] When the car door is opened, because the driver does not pay attention to the driving conditions of the non-motor vehicle behind, it will lead to serious traffic accidents
Therefore, the car door anti-collision warning system is introduced. In this system, the detection system is required to detect the situation behind the car door all the time. However, since the detector is installed at the position of the car door, it will move with the door, so the detection angle will also change accordingly, forming a detection blind spot. Therefore, it is necessary to keep the detection angle consistent with the door opening angle so that the detection direction of the detection system is always behind the door

Embodiment
[0021] In the method for detecting angle following in the vehicle door anti-collision warning system, a preferred solution is that in step S1, the displacement sensor is a displacement sensor based on an optical chip. The advantages of this displacement sensor are non-contact measurement, based on image processing, and high precision. The displacement sensor measures the arc length L formed by the rotation of the door at the measurement point, and the embedded CPU processing module has a built-in execution program, which executes S2 and S3 in sequence to obtain the rotation angle A required by the stepping motor 步 . The built-in driver of the embedded CPU processing module drives the I / O port to give the stepper motor control signal, and drives the stepper motor through the stepper motor driver 3 rotation angle A 步 . Thereby, the gear structure 4 is driven to rotate, the gear structure 4 meshes with the tooth structure on the adjustment ring 1, and the adjustment ring 1 is d...

The invention discloses a detection angle following method in an automobile door anti-collision early warning system, and relates to a sensor technology, in particular to a detection angle following technology in the automobile door anti-collision early warning system. The method comprises the following steps: S1, acquiring an arc length L formed by rotation of an automobile door at a measurementpoint; S2, calculating the opening angle A of the automobile door, S3, calculating the rotation degree step A required by a stepping motor, and S4, giving a specific pulse number through a single chipmicrocomputer and a stepping motor driver, and driving the stepping motor to rotate by the angle step A. The method has the beneficial effects that the detection angle is consistent with the openingangle of the automobile door, and there is no blind area in the area.
Description
technical field [0001] The invention discloses a detection angle following method in an automobile door anti-collision early warning system, in particular relates to sensor technology, especially the detection angle following technology in the automobile door anti-collision early warning system. Background technique [0002] When the automobile door is opened, serious traffic accidents can be caused because the driver does not pay attention to the driving conditions of the rear non-motor vehicle. Therefore, the car door anti-collision warning system is introduced. In this system, the detection system is required to detect the situation behind the car door all the time. However, since the detector is installed at the position of the car door, it will move with the door, so the detection angle will also change accordingly, forming a detection blind spot. Therefore, it is necessary to keep the detection angle consistent with the door opening angle so that the detection directio...
