说明：  基于labview，通过与单片机的串口通信，实现温度控制系统，包含帧头，停止位，校验位。可返回当前串口的温度值，并实时绘制温度曲线。
(Based on labview, serial communication with the microcontroller to achieve temperature control system, including header, stop bits, parity bit. Returns the current value of the serial port of the temperature and the temperature curve of real-time rendering.)
