测试环境

Window 10、Python 3.8.6

需求库

numpy pyserial

下载与Python版本匹配的pyserial与numpy模块，将其源文件复制至Python文件目录下，随后执行 ‘pip install 模块路径’指令（需要正确设置pip环境才可安装）

例程

#创建日期：2020年10月10日#版本：初版#此程序对应北醒TF系列默认配置下串口版本有效#此程序只提供参考和学习# -*- coding: utf-8 -*-import serial.tools.list_portsimport timeimport numpy as npser = serial.Serial()ser.port = 'COM55'    #设置端口ser.baudrate = 115200 #设置雷达的波特率def getTFminiData():   while True:      count = ser.in_waiting #获取接收到的数据长度      if count > 8:         recv = ser.read(9)#读取数据并将数据存入recv         #print('get data from serial port:', recv)         ser.reset_input_buffer()#清除输入缓冲区         if recv[0] == 0x59 and recv[1] == 0x59:  # python3            distance = np.int16(recv[2] + np.int16(recv[3] << 8))            strength = recv[4] + recv[5] * 256            temp = (np.int16(recv[6] + np.int16(recv[7] << 8)))/8-256 #计算芯片温度            print('distance = %5d  strengh = %5d  temperature = %5d' % (distance, strength, temp))            ser.reset_input_buffer()         if recv[0] == 'Y' and recv[1] == 'Y':  # python2 //此处标示出文件读取成功            lowD = int(recv[2].encode('hex'), 16)            highD = int(recv[3].encode('hex'), 16)            lowS = int(recv[4].encode('hex'), 16)            highS = int(recv[5].encode('hex'), 16)            lowT = int(recv[6].encode('hex'), 16)            highT = int(recv[7].encode('hex'), 16)            distance = np.int16(lowD + np.int16(highD << 8))            strength = lowS + highS * 256            temp = (np.int16(lowD + np.int16(highD << 8)))/8-256 #计算芯片温度            print('distance = %5d  strengh = %5d  temperature = %5d' % (distance, strength, temp))      else:         time.sleep(0.005) #50msif __name__ == '__main__':   try:      if ser.is_open == False:         try:            ser.open()         except:            print('Open COM failed!')      getTFminiData()   except KeyboardInterrupt:  # Ctrl+C 停止输出数据      if ser != None:         ser.close()

输出如下：

distance =   205  strengh =  5224  temperature =    52distance =   205  strengh =  5231  temperature =    52distance =   205  strengh =  5230  temperature =    52distance =   205  strengh =  5218  temperature =    52distance =   205  strengh =  5226  temperature =    52distance =   205  strengh =  5221  temperature =    52distance =   205  strengh =  5227  temperature =    52distance =   205  strengh =  5224  temperature =    52distance =   205  strengh =  5223  temperature =    52distance =   205  strengh =  5223  temperature =    52distance =   205  strengh =  5226  temperature =    52distance =   205  strengh =  5225  temperature =    52

运行过程中可能存在的问题：

1、

Traceback (most recent call last):  File "C:/Users/Administrator/AppData/Local/Programs/Python/Python37/test.py", line 1, in 
   
        import serial.tools.list_portsModuleNotFoundError: No module named 'serial'
   

解决办法：安装Python-serial 模块

2、

Traceback (most recent call last):  File "C:/Users/Administrator/Desktop/test1.py", line 3, in 
   
        import numpy as npModuleNotFoundError: No module named 'numpy'
   

解决办法：安装numpy模块

3、

Traceback (most recent call last):  File "C:/Users/Administrator/Desktop/test1.py", line 39, in 
   
        getTFminiData()  File "C:/Users/Administrator/Desktop/test1.py", line 11, in getTFminiData    count = ser.in_waiting #获取接收到的数据长度  File "E:\Python\lib\site-packages\serial\serialwin32.py", line 259, in in_waiting    raise SerialException("ClearCommError failed ({!r})".format(ctypes.WinError()))serial.serialutil.SerialException: ClearCommError failed (OSError(9, '句柄无效。', None, 6))
   

解决办法：设置端口名称为实验设备端口号
