针对铁路平面调车调度室进行优化整合,原有数字调车区长台由于无线电波的通讯距离受限,无法满足调车区长对调车组人员进行远程指挥和远程监控的需求,设计了Vo IP(Voice over IP)网络数字语音转发器,通过本设计将数字区长台和数字控制盒接入同一局域网,对数字调车区长台的操控距离进行了拓展,实现了调车区长对平面调车组人员的远程指挥和远程监控的能力。本设计给出了以S5PV210为核心,以Linux为操作系统,采用Vo IP为通信技术的软件硬件设计方法。该产品应用于数字平面调车作业系统中,解决了远程操控数字调车区长台的难题,开创了Vo IP技术在数字平面调车作业中的应用先例。
In view of the optimization and integration of the dispatching room for railway plane shunting, the original digital shunting dispatching station has been designed to meet the demand of long-distance command and remote monitoring of shunting personnel because of the limited communication distance of radio waves. IP (Voice over IP) network digital voice transponder, through the design of the digital area of Taiwan and the digital control box access to the same LAN, digital shunting area of Taiwan’s control distance has been extended to achieve shunting long on Flat shunting crew of the remote command and remote monitoring capabilities. This design gives the S5PV210 as the core, Linux as the operating system, the use of Vo IP for communication technology software and hardware design. The product is applied to the digital plane shunting operation system and solves the problem of remotely controlling the long shunting area of the digital shunting area and pioneers the application of Vo IP technology in the digital shunting operation.
