Research of Train Positioning Technology Based on GSM-R Network
Abstract In today's society, with the communication control technology, the rapid development of railway signal control technology and so on, the train control technology is also in constant growth. At present, in our country CTCS - 2, CTCS - 3 system, used in a variety of train positioning technology. Relatively typical of train positioning technology are: navigation prediction positioning system, global positioning system (GPS), geographic information systems and wireless occlusion center positioning technology and its integrated navigation positioning system, these systems have their own characteristics and scope but also have their own defects.
At present there are a variety of train positioning technology and positioning system, this paper introduces in detail, including GPS positioning system, a variety of positioning technology. The karman filter is widely used in the positioning technology. As a separate kaman's filtering algorithm in this paper has a specific embodiment.
GSM-R on GSM system and the communication platform for our train operation control system is using now. Railway monitoring center in order to ensure the safety of train running through the communication system to realize high-speed train control management. The joint of the train control system in the current status, this paper based on GPS, DR and the weighted K nearest train positioning technology, developed a positioning performance is superior to the traditional GPS/DR integrated positioning based on GSM - R network location fingerprinting positioning system.
