GPRS无线通信具有网络成熟、快捷登录、实时在线、无线移动、高速传输和按量计费且费用经济的特点。文章介绍了GPRS无线通信技术应用于高速公路可变情报板通信改造中的软硬件环境的构建及其系统功能。GPRS技术与可变情报板传统的有线光纤通信相比有着建设投资经济、建设周期短、维护方便且维护费用低等优点,因此,用GPRS无线通信代替远距离光纤通信有着广泛的应用前景。
GPRS wireless communications with network mature, quick login, real-time online, wireless mobile, high-speed transmission and volume billing and cost-effective features. This paper introduces the construction of software and hardware environment and its system functions in the application of GPRS wireless communication technology in the highway information exchange board. Compared with the traditional wired optical fiber communication with variable information board, GPRS technology has the advantages of economical investment, short construction period, easy maintenance and low maintenance cost. Therefore, GPRS wireless communication has wide application prospect instead of long-distance optical fiber communication.
