1）国标推送过来的每一个目录可能有多个设备
2）每一个目录推送信息都需要进行200 OK回复
3）海康推送过来的目录总数可能跟实际的推送设备数量不一致（有的时候还把目录当作设备推送过来），需要设置一个超时接收的标志，目前超时60秒收取不到数据，说明接收完成
关键字段的描述：
1 CivilCode 行政区域的划分编码
2 ParentID 当前设备或者目录挂载的上一级目录的国标编码
3 DeviceID 可能是一个设备，或者是一个目录，需要根据是否存在一个ParentID编码跟DeviceID一致，来判断是否是设备或者目录，如果有一致的，肯定是目录
4 SumNum 每一次推送一条目录都会携带总数
5 Parental 当为设备时，是否有子设备（必选） 1 有， 0 没有，目前在对接海康的平台时候，发现同步的所有数据都是0，不符合标准规范
查询目录
1）发送目录查询请求
