中文摘要：

2008年年初的百年罕见大雪袭击了中国南方大部分地区，近半个中国的交通大动脉全面瘫痪。一场大雪给中国带来了前所未有的困难。因此，需要研究出一种新型路面监控系统，来监测路面的温度和湿度信息，并根据路面的冰雪情况来执行相应的除雪融冰工作，这对于保证桥梁、涵洞、机场跑道等一些特殊位置的路面安全有着极其重大的意义。文中介绍了一种基于WSN（Wireless Sensor Network）和嵌入式平台的实时监控系统的实现方法。通过吨138微控制器和GPRS数字终端设备，将传感器采集到的温度和湿度数据经过GPRS网络分两路传输，一路传输到手机终端；另一路经Internet传送到固定IP地址的服务器上，客户端可以通过Intemet接收服务器上的数据进行分析和处理，对远程的路面进行实时的监测；同时当温度和湿度指标达到雨雪天气的参考设定值时，系统自动启动加热装置，对路面加热。在实验室的模拟雨雪环境下，对系统进行了测试。系统实现了自动加热水泥基路面和远程客户端实时监测路面信息，达到了预期效果，肯定了方法的可行性。

英文摘要：

At the beginning of 2008, a rare heavy snow hit most parts of southern China. Nearly half of China＇s traffic artery was terribly paralyzed. A heavy snow has brought us unprecedented difficulties. Therefore, it＇s necessary to come up with a new type of road surface monitoring system to monitor road surface temperature and humidity conditions. According to the situation of the road surface,this system will clear the snow and ice, which has a great significance to ensure road safety such as bridges, culverts and airport runway. A real - time monitoring system implementation approach based on WSN（Wireless Sensor Network）and ARM7 platform is described. The data of temperature and humidity acquired by sensors through the LPC2138 micro- controller provided by NPX and GPRS UFU is transferred to two terminals. One is a mobile phone and the other is a fixed IP address server. Client could analyze and deal with the receiving data to monitor the information of the road far away. At the same time, the system will automatically start the heating device for heating the road surface when data of temperature and humidity reaches the reference value of snow. Simulated rain and snow in the laboratory environment, the system has been tested. Automatic heating system of cement - based surface and remote client information in real - time monitoting of the road reach the desired results, which confirms the feasibility of the method.
