摘　　要：针对现有Arduino智能遥控设备中串口控制指令多采用扁平结构的字符或者字符串格式的局限性,提出了基于JSON的遥控指令串口通信控制系统。在该系统中,采用串口事件函数作为控制程序总体框架,以串口作为控制指令数据源,通过JSON编码方式,实现控制指令的格式化编码及解析,实现遥控终端通过WiFi等无线通信方式对Arduino设备的控制。以智能小车作为实验对象,对控制系统进行了验证。实验结果表明,控制算法可靠,控制程序相比原机程序的可读性、可维护性和扩展性得到了优化。Aiming at the limitation that the serial port control instructions in the existing Arduino intelligent remote control equipment mostly adopt the flat structure character or string format,a serial port communication control system of remote control instructions based on JSON is proposed.The serial event function is used as the overall framework of the control program,and the serial port is used as the data source of the control instruction.The format coding and analysis of the control instruction are realized through the JSON coding method,and the remote control terminal can control the Arduino device through WiFi and other wireless communication methods.Taking the intelligent car as the experimental object,the control system is verified.The experimental results show that the control algorithm is reliable,and the readability,maintainability and expansibility of the control program are optimized compared with the original program.
