集通公司800MHz列尾和列车安全预警系统技术方案

Technical Scheme of Jitong Company 800MHz Train Tail and Train Safety Pre-alarm System

集通公司管内使用的是450MHz机车无线列调通信系统,随着列车运行对数加密和线路施工维护任务增多,单纯依靠450MHz无线列调通信系统已远不能满足当前运输生产和安全的需要。使用800MHz列尾和列车安全预警系统后,可实现列车车次、速度、位置、状况和列尾风压信息的传送,以及列车二次事故防护信息的传送等,使车与车、车与地、车与人及地与车之间形成了一个综合性的信息系统,为运输生产安全发挥重要作用。

450MHz cab radio communication systems for train dispatch are used within Jitong company. With the increasing high density of train traffic and the increase of wayside maintenance tasks, the 450MHz communication system cannot meet the needs of current transportation production and safety. Af- ter the introduction of 800MHz train tail and safety pre -warning system, which can enable the transmis- sion of the data including train number, speed, position, status, and train tail wind pressure, secondary accident protection data for trains, a comprehensive information system is formed between train and train, train and ground, train and people, ground and train to play an important role for the safety of transporta- tion.
