摘要
在80cm×80cm×80cm的立方空间制作了可见光室内测距装置,通过LED控制电路进行控制和驱动,通过硬件系统和软件程序实现在3个LED正常照明的情况下,测量电路根据传感器检测信号判定传感器的位置等功能。采用超声波辅助测距法,在充分考虑LED拓扑结构对测距性能影响的基础上,利用部署在室内的多个LED,合理选择其中3个LED作为发射节点,通过超声波测到距离采用载波分配法从而获得定位目标位置信息。
This system in 80 cm by 80 cm by 80 cm cubic space made visible light indoor dme, through the LED control circuit to control and drive, through the hardware system and software program in the case of three normal LED lighting, measurement circuit based on sensor detection signal to determine the position of the sensor, and other functions. By ultrasonic assisted ranging method, in full consideration LED topology of ranging performance impact, on the basis of using the deployment of multiple leds indoors, reasonable choose three leds as launch nodes, through ultrasonic to measure distance using the carrier distribution method for target location information.
