Abstract
The invention relates to a method for setting temporary speed restriction for a train in a degraded mode. The method includes the following steps that an interlock system acquires temporary speed restriction information of an ATS; the interlock system acquires temporary speed restriction information in an interlock upper computer; the temporary speed restriction information in the interlock system is processed; the interlock system transmits the temporary speed restriction information to an encoder to be encoded; the encoded temporary speed restriction information is transmitted to a trackside speed restriction beacon by the encoder; a beacon antenna of the train acquires front speed restriction information when passing through the speed restriction beacon, and the speed of the train can be adjusted according to the front speed restriction condition; whether the temporary speed restriction information transmitted by a DCS is received or not is judged by the train, if yes, the train shields the temporary speed restriction information from the speed restriction beacon, and the temporary speed restriction information transmitted by the DCS is used as the reference; if not, the temporary speed restriction information from the speed restriction beacon is used by the train. Compared with the prior art, the method for setting temporary speed restriction for the train in the degraded mode has the advantages of improving traffic safety, efficiency and the like.
Description
Technical field
The present invention relates to field of urban rail, especially relate to a kind of method that train to degraded mode arranges temporary speed limitation.
Background technology
In urban track traffic operation, often need to carry out lower than permissible velocity one section of circuit and there is the restriction of ageing speed, mainly comprising planned speed limit that Contraction in Site causes and the sudden speed limit that disaster, breakdown of equipment cause; The region of temporary speed limitation can arrange multiple, and has fixing terminal and speed limit.
At present, in city rail traffic signal system, only can realize temporary speed limitation by automatic train monitor (hereinafter referred to as ATS) to train under communication-based train control pattern (hereinafter referred to as CBTC) and manage; Watch keeper arranges temporary speed limitation by ATS upper computer, temporary speed limitation information transfers to train by line controller (being called for short LC) by wireless transmitting system (hereinafter referred to as DCS) again, and speed-limiting messages is remained valid before being cancelled by watch keeper always.
Due to can not real time bidirectional communication under other degraded modes, cannot realize carrying out in real time interim speed restriction to train, the way that temporary speed limitation takes is set at present under degraded mode and be open calling-on signal or force train operating speed unrestricted model (hereinafter referred to as RM pattern) operation; No matter use which kind of method have speed limit fixing can not adjust with cannot real-time update speed-limiting messages, and then the shortcoming of impact driving efficiency; And these two kinds of methods all need watch keeper to carry out too much indirect operation, mistake cannot be avoided to cause the appearance of safety misadventure, also increase the operation pressure of watch keeper and driver simultaneously.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of method being arranged temporary speed limitation by the train of speed limit beacon to degraded mode is provided, simultaneously this method does not affect the speed limiting function under CBTC pattern, can switch flexibly according to the pattern of circuit.

Fig. 2 is the hardware configuration schematic diagram that the present invention realizes.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment:
As shown in Figure 1, a kind of method that temporary speed limitation is set by the train of speed limit beacon to degraded mode, the method comprises the following steps:
Step S1, after interlock system apparatus starts, system initialization;
Step S2, interlock system is attempted communicating with ATS system, sends request to ATS system;
Step S3, whether interlock system judges ATS system whether fault by the feedback information of ATS system, communicate normal: if normally, then execution step S4; If fault, then perform step S5;
Step S4, sets up with ATS system and communicates, and obtains the temporary speed limitation information in ATS, if speed-limiting messages is empty, then gives tacit consent to ATS system and does not arrange temporary speed limitation;
Step S5, thinks ATS system jam, and all is insincere message from ATS system message, shields the temporary speed limitation information from ATS system, and produces on interlocking upper computer and report to the police;
Step S6, interlock system obtains temporary speed limitation information in interlocking upper computer, if speed-limiting messages is empty, then gives tacit consent to and does not arrange temporary speed limitation;
Step S7, the temporary speed limitation information in process interlock system, if receive the afoul temporary speed limitation information of the same area from interlocking upper computer and ATS upper computer, then performs step S8; If information is not conflicted or only received the information of triangular web, then perform step S9; If all without temporary speed limitation information, then wait for that next cycle performs step S2;
Step S8, calculates temporary speed limitation information the strictest;
Step S9, temporary speed limitation information transmission is encoded to coder by interlock system;
Step S10, coder by coding after temporary speed limitation information transmission to trackside speed limit beacon;
Step S11, when the beacon antenna of train gets front speed-limiting messages through speed limit beacon, according to front speed limit situation adjustment train speed;
Step S12, train judges whether to receive the temporary speed limitation information transmitted by DCS: if so, perform step S13; If not, step S14 is performed;
Step S13, train shielding, from the temporary speed limitation information of speed limit beacon, is as the criterion with the temporary speed limitation information transmitted by DCS;
Step S14, train adopts the temporary speed limitation information from speed limit beacon;
Step S15, train carries out speed limit in the region of speed limit, terminates.
Even if also temporary speed limitation can be arranged to any region of circuit by this process under non-CBTC pattern.
As shown in Figure 2, watch keeper not only can arrange temporary speed limitation at ATS upper computer, also can arrange temporary speed limitation on interlocking upper computer.
Need say to tell speed limit process is set arrange between certain two station temporary speed limitation to produce unexpected situation:
Watch keeper has notice, and has emergency situations to need speed limit 50km/h between station A and station B;
It is 50km/h that watch keeper arranges temporary speed limitation between the station of station A and station B at ATS upper computer;
Temporary speed limitation information transfers to all trains travelled under CBTC pattern by DCS, and the train under CBTC pattern passes through with the speed lower than 50km/h by during this region;
Simultaneously, temporary speed limitation information sends to interlock system by ATS system, interlock system obtains temporary speed limitation information and carries out coded transmission to the speed limit beacon being arranged in station A platform and station B platform through coder, get the speed-limiting messages in station A and B interval, station when the train under degraded mode passes through a station A platform or station B platform, train passes through with the speed lower than 50km/h by during this region.
In addition, if ATS system also et out of order at this moment, watch keeper directly can arrange temporary speed limitation information at interlocking upper computer, all CBTC pattern trains and all degraded mode trains pass through a station A platform or station B platform time get the speed-limiting messages in station A and B interval, station, train passes through with the speed lower than 50km/h by during this region.
