Embodiment Construction

[0021] In actual operation, the instrument pointer is assembled manually. However, in application, due to the existence of manual assembly errors, after the pointer receives the instruction, the position it points to will often have a deviation angle from the scale on the meter, which makes the value that can be read on the meter deviate. In order to solve the above problems, the present invention realizes the automatic adjustment of the pointer through the following specific implementation methods.

[0022] A fully automatic pointer adjustment system described in this embodiment takes the ZB2202A instrument as an example, and adjusts the pointing of the 0 scale on the instrument panel. The system includes: a camera, a CAN generator and an industrial computer. The camera is used to collect The dial image of the instrument, the image output end of the camera is connected to the image input end of the industrial computer, the control signal output end of the industrial computer ...

Abstract

The invention provides a fully automatic pointer adjustment system and relates to the technical field of automobile instrument debugging. The fully automatic pointer adjustment system aims to solve the problem that the manual assembly of a pointer easily causes the pointer to have a deviation. According to the fully automatic pointer adjustment system, an instruction is sent to the instrument pointer through a CAN signal source, so that the instrument pointer points to an appointed scale; an instrument image is collected and linearly processed to obtain an angular difference X between a pointer center line and a scale center line; the number of microsteps needed for the movement from the pointer center line to the scale center line is calculated according to the angular difference X; the number Y of the microsteps is written into an instrument controller, and the number of microsteps needed for a motor to point to the appointed scale is updated to be Y, so that the adjustment of the pointer pointing to the appointed scale is completed. According to the fully automatic pointer adjustment system, partial instrument adjustment and detection work can be done.

Description

technical field [0001] The invention belongs to the technical field of automobile instrument debugging. Background technique [0002] In the automobile combination instrument industry, due to factors such as many product types, large structural changes, and fast update speed, manual assembly of pointers often occurs during the assembly process of instrument dial pointers. However, the manual assembly operation often cannot guarantee that the indication of each pointer is consistent and correct after the assembly is completed. At the same time, the reasons for the existence of equipment and pointers may also cause certain deviations after the pointer is assembled. Therefore, in actual operation, once the incorrect situation of exceeding the pointer indication range occurs, the pointer needs to be removed, which wastes manpower and material resources, and requires a certain amount of operating time. Contents of the invention [0003] The present invention aims to solve the...
