A Study on Position Detection System of KHST

We have developed a new measurement system by using GPS to complement those errors. In general, GPS receivers are composed of an antenna, tuned to the frequencies transmitted by the satellites, receiver-processors, and a highly-stable clock. The GPS mounted on the roof of TT4 in KHST receives a signal from the RS232 communication port, and it is connected to the network system in TT3 after converting with TCPIP communication. It is able to track the position of vehicle and synchronize the signal from different measurement system simultaneously. Therefore it is able to chase the fault occurrence, track inspection and electrical interruptionat real-time situation more accurately. There is not an error coursed by vehicle conditions such as slip and the slide.
