数据编码模块

OneNet平台设备开发文档

开发文档链接：ONeNet设备开发文档

数据编码代码如下：

class Converter(object):def to_hex(data):# onenet平台 .Json数据类型byte_list = '\x03'# 获取ANSI编码及长度list = data.encode('mbcs')len_list = len([format(i, 'X') for i in list])#塔石4G DTU编码格式byte_list += chr(0) + chr(len_list)for i in list:byte_list += chr(i)byte_list += '\r\n'# 串口使用比特流传输s_byte_list = bytes(byte_list, encoding='UTF-8')return s_byte_list

串口模块

class mSerial:def __init__(self, com, bps, timeout):self.port = comself.bps = bpsself.timeout = timeoutglobal Rettry:# 打开串口，得到串口对象self.main_serial = serial.Serial(self.port, self.bps, timeout=self.timeout)# 判断是否打开成功if (self.main_serial.is_open):Ret = Trueexcept Exception as error:print("---Error---：", error)# 打开串口def Open_serial(self):self.main_serial.open()# 发送数据def Send_data(self, data):self.main_serial.write(data)# 关闭串口def Close_serial(self):self.main_serial.close()print(self.main_serial.is_open)  # 检验串口是否打开
