Abstract:

On-board communication and positioning methods can assist subway vehicles in understanding themselves and the surrounding environment, and are an important part of realizing communication-based train control. In-vehicle positioning and communication technology integrates its own theoretical development, and combines research results in multiple fields to develop related theories and technical methods suitable for various application needs. The study summarizes and sorts out a variety of on-board positioning technologies for the subway operating environment, the evaluation standards of positioning methods and the related research results of subway on-board communication networks. Benefit from the rapid development of environmental perception technology, computer technology and control decision-making technology, the vehicle positioning and communication technology has rapidly developed. With the improvement of subway intelligence, on-board positioning and communication technology will develop in a direction that is more robust and more integrated.

Key words: metro, on-board communication, positioning technology, communication technology, train control system, triangular positioning, tunnel positioning, train control
