摘　　要：目前,高铁桥梁正在广泛的建造之中,为确保高铁全线的安全运行,可在桥梁上安置一个搭载图像信息采集工具的可远端操控的小车,对桥梁进行周期性图像采集与分析。本文介绍了一种该小车的设计方法,实现了通过3G网络对小车的远端控制,以及对小车运行状态的实时反馈,并可通过3G网络安全传输大量的现场图像采集数据。本文介绍了由C++编写的程序读写西门子S7300系列PLC内部寄存器值的方法,通过3G路由器走GPRS网络实现远程两端计算机的Modb-usTcp通讯协议下的无线控制指令的传输,以及在不稳定网络状态下实现大文件拆解传输,断点续传的方法。At present,the high speed rail is extensive built.For the safety of its operation,we set a car on the bridge.With this car,we can detect the safety of the bridge periodicity.Take advantage of the 3G net,we can control the car remotely,we can get the information of the car＇s running status at the real time and we can get the pictures back from the car when we want.The PLC used in the industrial field is always real-time monitored by Configuration software,easy and intuitive.In this paper,we introduce a method to read out values from S7300 Siemens PLC＇s internal registers and write values into S7300 Siemens PLC＇s internal registers.With the GPRS internet supplied by a 3G router,we can transmit the control orders between two long-range computers under the protocol of modbustcp.When the network is unstable,how we can transport large files and how we can go on sending the data from the breakpoint where the net is disconnected.
