基于WSN嵌入式智能视频小车的研究与设计

Embedded Intelligent Video Car Based on WSN

以直流电机驱动的小车为载体设计了一种嵌入式车型机器人,使用STC15系列IAP15F2K61S2微控制器作为智能小车的控制核心,采用Wi Fi无线通信模块与上位机通信.通过红外光电传感器检测跑道轨迹,电机驱动芯片L298N结合PWM信号控制直流电机前进的速度和方向,超声波测距模块则可以检测障碍物的距离以准确避障.测试结果表明,小车具备了光电循线、超声波测距、视频监控及无线通信等功能.

The study designed a robot with embedded modules,which used the DC motor- driven car as the carrier. It used STC15 series IAP15F2K61S2 micro- controller as the core control of the smart car,and Wi Fi wireless communication module to communicate with the host computer. It detected the trajectory of the track by infrared sensors,used motor- driven chip L298 N combined with PWM signal to control the forward speed and direction of the DC motor. The ultrasonic ranging module could detect the exact distance in order to avoid the obstacle. The test results of the smart car prototype showed that the car had functions of following the track photoelectrically,ultrasonic ranging,video surveillance and wireless communications.
