Embodiment Construction

[0041] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] The position of the signal machine on the site can be known through the topology of the field equipment. Once the position of a signal machine is determined, the line section around the signal machine can be calculated through the topological relationship of the field equipment. According to the scope, it can be divided into signal external parties The first section and the first section of the inner side of the signal, the outer side and the inner side section of each signal machine are determined according to the line topology and field equipment.

[0043] Since the function of the signal machine is to instruct the train to drive according to the signal display, a...

Abstract

The invention discloses a method for computing a signaler trans-voltage command. The method specifically comprises the following steps of: enabling a zone control system to acquire the position of the signaler and the external section of the signaler; judging whether the external section of the signaler is in an occupied state or not, if so, determining the position of a train which is closest to the signaler; and judging whether the head and the tail of the train cross the signaler or not according to a position relation between the train and the signaler, computing to generate a corresponding signaler trans-voltage command, sending the signaler trans-voltage command to an interlock which corresponds to the zone control system, and controlling a moment when the signaler is switched from an enabling signal to an inhibiting signal by using the interlock. Due to the adoption of the method, undesired emergency brake of the train is avoided, the running efficiency of the train in a CBTC (Communication Based Train Control) mode is increased, and running of multiple rows of CBTC trains in the same route or the same zone is realized.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a calculation method for a signal machine cross-voltage command of an urban rail CBTC (Communication Based Train Control) system. Background technique [0002] With the rapid development of wireless communication technology, the reliability and availability of wireless communication have been greatly improved. Communication Based Train Control (hereinafter referred to as CBTC) system is the development trend of rail transit train operation control system in the future. The CBTC system is a new generation of signal system that breaks through the boundary of fixed blockage and is completely separated from the track circuit. It provides more accurate train control, continuous train safety separation and overspeed protection through high-precision train positioning technology and uninterrupted train-ground communication. The train can realize safe operation in a shorter ru...
