Design of environmental adaptive gray tracking sensor

针对灰度循迹传感器在环境光照发生变化时不能自动适应调节基准电压的问题,设计了一种新型灰度循迹传感器。该传感器将微处理器与传统灰度循迹传感器电路进行结合。微处理器对多路传统灰度传感器电路采集到的检测电压信号进行融合计算,得到该环境光照下最优基准电压,以解决传统灰度循迹传感器基准电压无法自适应环境光照,存在循迹误判的问题。实验表明,该传感器设计方案提高了灰度循迹传感器循迹准确性,提高了传统灰度循迹传感器环境适应性。

In this paper,a new gray-scale tracking sensor is designed to solve the problem that the gray-scale tracking sensor cannot automatically adjust the reference voltage when the ambient light changes.The sensor combines a microprocessor with a traditional gray-scale tracking sensor circuit.The microprocessor performs fusion calculation on the detection voltage signals collected by the multi-channel traditional grayscale sensor circuit to obtain the optimal reference voltage under the ambient light to solve the problem that the traditional grayscale tracking sensor reference voltage cannot adapt to the ambient light and there is the problem of tracking misjudgment.Experiments show that the sensor design scheme improves the tracking accuracy of the gray-scale tracking sensor and the environmental adaptability of the traditional gray-scale tracking sensor.
