1. 单个socket中接收消息的方法要使用局部变量而非全局，避免消息频发时产生脏数据

优化后的关键代码

recieveInfo() 方法通过返回内部处理后的 msg 进行传递
if (data.indexOf("0103") == -1) { 这里增加了判断, 对数据（非注册和心跳）再进行一遍过滤

void CustomTcpSocket::handleReadyRead()
{// 信号灯闪烁emit SignalRelayer::instance()->msgInOut(true);// 接收到消息QString msg = recieveInfo();// 解析收到的数据parseRegisterMsg(msg.split(",")[0], msg.split(",")[1]);// 判断注册的设备号是否可用if(!Myapp::devEnabled(devNumber)) {return;}// 判断是否是业务数据if(isNotBusinessInfo()) return;// 不是0103开头的数据不处理QString data = msg.split(",")[1];if (data.indexOf("0103") == -1) {qDebug() << "不是0103开头数据不做处理, data: " << data;return;}// 电路数据处理handleReadReadImpl(data);
}
