本仓库是根据《污染物在线监控（监测）系统数据传输标准 HJ 212-2017.pdf》文档，对接收到的212协议报文进行接收和解析。

HJ212协议简介

做环保相关的，有时需要对212协议进行拆包和解包。HJ212协议是一种字符串协议，数据传输通讯包主要由包头、数据段长度、数据段、CRC校验、包尾组成，其中“数据段”内容包括请求编码、系统编码、命令编码、密码、设备唯一标识、总包数、包号、指令参数。请求编码为请求的时间戳，系统编码ST统一规定为22，命令编码CN为该数据包的时间类型，访问密码、设备唯一标识在对接时由平台提供，指令参数为数据内容。通讯协议的数据结构如图4所示。 通讯协议的数据结构 <center>图4 通讯协议的数据结构</center>

通讯包结构组成

名称 类型 长度 描述
包头 字符 2 固定为##
数据段长度 十进制整数 4 数据段的ASCII字符数。例如数据段的字符数为128，则写为“0128”
数据段 字符 0<=n<=9999 变长的数据
CRC校验 十六进制 4 数据段的校验结果，例如C901，如果CRC错，即执行超时
包尾 字符 2 回车换行（\r\n）

《污染物在线监控（监测）系统数据传输标准》简称《HJ212-2017》标准PDF文档可以从中华人民共和国生态环境部的官网下载，具体地址为：HJ212-2017》标准PDF文档 如下图所示： HJ212-2017标准下载 目前HJ212标准协议已经发布了两个版本，一个是HJ/T 212-2005，另一个是 HJ 212-2017，最新的HJ 212-2017下载地址为：污染物在线监控（监测）系统数据传输标准(HJ 212-2017代替HJ/T 212-2005)

使用 NetPackage 类进行212协议包的解析，

例如有如下212协议数据报文：
