高速公路嵌入式联网报警系统的设计

当高速公路收费系统中车辆强行闯关或发生其他突发事件时,亭端收费员通过按动报警开关将报警信号及时传送到收费站,收费站再将该报警信号传送到收费中心。该嵌入式联网报警系统主要由站端报警系统、中心报警系统控制器和中心报警系统监控管理软件组成,设计好的整个报警系统已被安装在江苏省沿江(南京-太仓)高速公路的各个收费站和收费中心,现该系统已经正常运行两年,从而证明了该系统在实际应用中的可靠性。

Design of the online-embedded alarm system on the expressway

The online-embedded alarm system on the expressway is mainly utilized in the case that vehicle passes the toll station without being allowed or with something unexpected occurring. When the toll collector in a certain terminal station pushes the alarm switch, the alarm signal will reach the control center via the toll station. This kind of online-embedded alarm system is composed of terminal alarm system, center alarm controller and center alarm supervising software, and has been successfully employed in the toll stations and control centers of the Nanjing-Taicang the expressway in Jiangsu Province for almost a year. The good performance shows that the system proposed is reliable and feasible in actual application. With the improving application of digital signal processing and transmission, alarm system on the expressway highways would develop to its combination with digital video monitoring system. Technickes of graphics mode would effectively help the alarm system develop more intelligently and practically.
