Abstract

The invention relates to a rail dispatching system with a scan priority. The rail dispatching system comprises a server unit (1), a vehicle-mounted station (2), a fixed station (3) and a dispatching desk unit (4), wherein the server unit (1), the vehicle-mounted station (2) and the fixed station (3) are mutually connected by a bus; the server unit (1), the vehicle-mounted station (2) and the fixed station (3) are mutually connected wirelessly; and both of the vehicle-mounted station (2) and the fixed station (3) are provided with a wireless transceiver used for sending out a periodic scanning signal and receiving a calling signal. Compared with the prior art, the vehicle-mounted station and the fixed station of the invention can respectively transmit the periodic scanning signal to the server unit, periodically detect whether there is a calling signal from the dispatching desk unit, so as to timely respond to the call and joint a call group, give a high priority to an important call and can interrupt a low priority call; therefore, the rail dispatching system with the scan priority provided by the invention has the advantages of being quick in response, high in reliability and wide in applicability.

Description

technical field [0001] The invention relates to a radio system, in particular to a rail traffic scheduling system with scanning priority. Background technique [0002] The special wireless communication system for rail transit is a set of automatic dispatching communication system developed based on the platform of TETRA digital trunking system and the train position information and train number information of the rail transit signaling system. The system consists of switching control center, base station equipment, dispatching equipment, network management equipment, user terminal equipment and so on. It provides a reliable means of communication for voice and data information exchange between fixed users (control centers, depot / parking dispatchers, station attendants, etc.) and mobile users (train drivers, disaster prevention personnel, maintenance personnel). It provides an important guarantee for driving safety, improving transportation efficiency and management level, ...
