Sensor Network Infra Test for Monitoring of High-Speed Railway

초록

Hihg-Speed Railway runs at the speed up to 300Km/h and is complex system that works many electronic devices and machines together. Its system complexity is very high, so sensors that check the system status and communication systems are very important. And sensors installed this kind of high-speed railway make data that is several Mbytes per minute, so measurements for trains usually use wire-based networks. Most of trains are divided into two part, up-side and down-side. And sensors for important data are attached in down-side, but monitoring servers and monitoring equipments are installed in up-side. Here is a problem. When up-side and down-side is divided, because of maintenance etc, the wired network between up-side and down-side has to remove, and after repairing, connect again. If trains use 6LoWPAN to remove this kind of inconvenience, data wire can be eliminated. In addition, If trains use a high-speed wireless mobile communication network like HSDPA, it’s possible to send monitoring data, that is collected in inside of trains, at the server of outside remote place. Thus it can be a central control system.
