//负载均衡思想
//目的，后台管理会给终端分配所属交换服务器
//终端处理方法：
//1、每次开机都会访问管理服务器ManaIP，如果成功则获取到非0的IP，检测是否与本地原PIP一致，如果不一致，则重置模块参数，并保存新PIP到本地，然后重启整机系统
//2、如果开机后登陆不上(判定A)交换IP，则启动登陆管理服务器获取新IP，如果与本地一致，不改变本地参数，继续登陆交换服务器，如果一致，则更新并复位整机系统
//3、如果成功登陆过后，然后掉线后再也登陆不上(判定B)交换服务器，则启动登陆管理服务器获取新IP，如果与本地一致，不改变本地参数，继续登陆交换服务器，如果一致，则更新并复位整机系统
//判定A:即未登陆状态，从配置完POC参数后开始计时(PocTimeoutCnt)，如果登录成功则重置PocTimeoutCnt计数，且不再计数，如果掉线后则再次清PocTimeoutCnt且开始计时，超过3分钟(待定)则判定成功
//判定B:与判定A后半部分类似，即从掉线后开始计时
//注意，执行访问管理服务器时，我们就不处理GPS了。因为此模块查询TCP状态返回不带SOCKET，且代码模式如果更改会比较复杂
