杭州北海程控设备有限公司日前研制开发出一种称为新一代SLD——9501的高速公路电话报警系统,该系统集智能化微处理技术、数字交换技术、GIS技术与调度指令广播通讯技术于一体,这表明我国在高速公路紧急情况自动报警的开发方面不再是空白。 这种报警系统由主机、传输线和分布于高速公路两侧的通话柱构成。主机采用多冗余结构高可靠性设计,公共部分均采用双套热备份工作,有故障时自动转换并发出报警、接警记录、处警,完成电子地图显示呼叫的位置等任务。
Hangzhou Beihai Program Control Equipment Co., Ltd. recently developed a called a new generation of SLD-9501 Expressway telephone alarm system, the system integrates intelligent micro-processing technology, digital switching technology, GIS technology and dispatch instructions broadcast communications technology in one , Which shows that our country is no longer blank in the development of automatic highway emergency alarm. This alarm system consists of a mainframe, transmission lines and call posts located on both sides of the highway. The host adopts multi-redundant structure and high reliability design. Both public parts work in double sets of hot backup. When there is a fault, they are automatically converted and alarm, alarm record and alarm are displayed. The electronic map displays the location of the call and other tasks.
