摘　　要：实时监测公路路面,特别是高速铁路的平整度是确保行车安全的必备条件,而要达到这一条件,车载动态振动测量是其首选技术之一。而在这一技术中,路面故障点位置的确定是技术关键。通过对GPS数据传输模式以及NMEA-0183协议的分析,利用VB6.0中的MSComm控件实现PC机与GPS接收机之间的串行通讯,可实现对运载工具的行驶时间、高度、经度和纬度等信息在计算机显示器上的实时显示,以达到对故障点的实时监测。该项技术不仅为路面的平整度动态检测提供了技术支撑,而且也为这项技术的进一步研究提供了参考。Real-time monitoring of highway pavement, especially roughness of the high-speed railway is to ensure that the safety degree of prerequisite, in order to achieve this condition, vehicle＇ s dynamic measurement is one of preferred technologies. In this technique, the fault location of road is the key technology. Through analyzing GPS data transfer mode and NMEA-0183 agreement,the serial communication is implemented by using the communication control MSComm in VB 6.0 . After the commissioning of the program, MSComm control can realize real-time information displays on the monitor such as time, height, latitude and longitude of runing vehicles, achieve real-time monitoring of the fault. The technology not only provides technical support for the pavement roughness dynamic test, but also provides a reference for the technology.
