3.14 改為透傳
3.15 Line 1583 delay4ms()刪除，加快發給模塊速度
3.19 powerkey 上電之后延時過短（40s）會導致cipstart不能連接。
不使用透傳，改回成AT命令模式發送
發完at+cipsend=xx之后，必須等待大于號的應答
加上對send ok 的判斷。
5。29 最新版和小莊帶到廈門的手工版只有在線燈的改變，只在FuntionPin.h中改動了。
6.6 莊添加：目的：實現信號強度燈指示
1.屏蔽掉所有信號強度燈操作；
2.在proc_min中加讀信號強度；
3.在proc_timeover中加信號強度燈的亮暗設置
4.在主循環while(1)之前加信號強度讀取
6.16 刪除SoftDog,移動初上電55AA里的語句
6.19 掌機設置終端號的協議解釋里加了個ConnectIP(),目的:讓后臺原來連接的終端號斷線,讓新設的終端號上線
6.21 增加采集器對掌機的485端口檢查命令的應答（原來只有紅外）
