Tracking control method based on white light sensor

Abstract

The invention discloses a tracking control method based on a white light sensor. The tracking control method comprises the steps of signal acquisition of the white light sensor, signal conversion andprocessing, parameter setting control of an upper computer, signal decomposition six-stage line patrol of the upper computer, and the like. A control system used in the tracking control method comprises the upper computer and a lower computer, the upper computer comprises a main control module, a direct-current adjustable voltage reduction and stabilization power module, a driver and a motor, themain control module is connected with the driver, the driver is connected with the motor, and the lower computer comprises a single chip microcomputer and the white light sensor. The main control module of the upper computer is connected with the single-chip microcomputer of the lower computer; the white light sensor comprises an LED lamp module, a sampling trigger module, an analog-to-digital conversion module, a calculation comparison module and an output interface module. The illumination intensity is automatically calculated and fed back in real time, and the problem that the error betweenrobot tracking and sensor illumination intensity adjusting precision is large can be well solved.

Description

technical field [0001] The invention belongs to the technical field of sensor control, and in particular relates to a tracking control method based on a white light sensor. Background technique [0002] At present, sensors are widely used in the detection field. Infrared sensors, color mark sensors, etc. are commonly used in the field of robot line inspection. They emit infrared rays and other light as receivers, and trigger signal responses as detections after receiving them. False detections are prone to occur in the process. [0003] Color mark sensors and infrared sensors are commonly used in robot tracking control on the market. Generally, it is necessary to use manual visual inspection to debug the sensors. Users can only estimate manually based on experience. Usually, the adjustable resistance on the grayscale sensor is adjusted by a screwdriver. This adjustment is quite troublesome, and it is prone to problems, resulting in low precision, large measurement errors, a...
