Temporary speed limiting method based on a plurality of in-place working stations and DSU (Database Storage Unit)

Abstract

The invention discloses a temporary speed limiting method based on a plurality of in-place working stations and a DSU (Database Storage Unit). The temporary speed limiting method comprises the following steps that: the DSU receives temporary speed limiting messages transmitted by the plurality of in-place working stations, the DSU and the plurality of in-place working stations belong to the same ATS (Automatic Train Supervision) system; the DSU acquires the temporary speed limiting information corresponding to the identifier of the DSU according to the identifier of the DSU; and the temporary speed limiting information is transmitted to a ZC (Zone Controller) so that the ZC controls a CBTC (Communication Based Train Control) train to run according to the temporary speed limiting information, wherein the temporary speed limiting messages comprise identifiers of the in-place working stations, which transmit the temporary speed limiting messages, and also comprise an identifier of each DSU and temporary speed limiting information corresponding to the identifier of each DSU. According to the invention, the temporary speed limiting information of the plurality of in-place working stations are received through the DSU so as to ensure the safety, stability and fault tolerance of a train control system in the CBTC running mode.

Description

technical field [0001] The invention relates to the field of signal control, in particular to a temporary speed limiting method based on a multi-site workstation and a DSU. Background technique [0002] With the continuous development of urban rail transit, the communication-based CBTC (Communication Based Train Control) has brought great changes to the signal system of urban rail transit, and the safe operation of trains is becoming more and more important. At present, my country's intelligence in the field of train control is low and there is too much manual intervention, especially in the temporary speed limit section of the blind spot of train control. Drivers only use temporary speed limit signs on the ground to identify information, and there is a lack of automatic speed limit transmission and automatic control measures. , with the increase of train speed and density, higher requirements are put forward for the safety and automation of the entire train control system wh...

At present, my country's intelligence in the field of train control is low and there is too much manual intervention, especially in the temporary speed limit section of the blind spot of train control. Drivers only use temporary speed limit signs on the ground to identify information, and there is a lack of automatic speed limit transmission and automatic control measures. , with the increase of train speed and density, higher requirements are placed on the safety and automation of the entire train control system while operating efficiently

[0003] The traditional temporary speed limit scheme is only aimed at a single on-site workstation, that is, an on-site workstation can only issue a temporary speed limit command to its DSU (Database Storage Unit), and other on-site workstations cannot The DSU issued a temporary speed limit order
