Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of railway train control systems, and particularly to a method, device, equipment and storage medium for handling temporary speed limits. Background Technique

[0002] Current temporary speed limit technologies are mainly used in lines of Train Control System Level 2 (China Train Control System - 2, CTCS - 2), Train Control System Level 3 (China Train Control System - 3, CTCS - 3), and Communication Based Train Control (CBTC). In the CTCS - 2 train control system, the temporary speed limit server sends temporary speed limit information to the train control center, and the train control center sends the temporary speed limit to the Automatic Train Protection (ATP) through an active balise. The ATP analyzes the temporary speed limit information through the active balise, calculates the braking curve, and monitors the safe operation of the train. In the CTCS - 3 train control system, the temporary speed limit server sends temporary speed limit information to the Radio Block Center (RBC), and the RBC sends the temporary speed limit information within the train movement authority to the ATP through wireless communication. The ATP calculates the braking curve according to the train movement authority information and the temporary speed limit information sent by the RBC, and monitors the safe operation of the train. In the CBTC train control system, the Automatic Train Supervision (ATS) sends the temporary speed limit information to the Zone Control Center (ZC), and the ZC sends the temporary speed limit information within the train movement authority to the ATP through wireless communication. The ATP calculates the braking curve according to the train movement authority information and the temporary speed limit information sent by the ZC, and monitors the safe operation of the train.

[0003] However, the temporary speed limit of the CTCS - 2 train control system mainly relies on active balises, the temporary speed limit of the CTCS - 3 train control system mainly relies on Global System for Mobile Communications – Railway (GSM - R) wireless communication, and the temporary speed limit of the CBTC system mainly relies on Long Term Evolution (LTE) network. For general speed lines and heavy - haul lines, due to the inability to meet the conditions for covering wireless networks or arranging active balises, it is impossible to use temporary speed limit technology to monitor the safe operation of trains under conditions such as line construction and rain and snow weather. Moreover, laying GSM - R or LTE wireless networks along the entire railway line is not adopted because of high cost and long cycle.

[0004] Moreover, for the lines with only in-station coverage of wireless communication, if the existing temporary speed limit processing method is adopted, the disadvantages are as follows: (1) If the temporary speed limit processing method of the CTCS-2 level train control system is adopted, a large number of active balises need to be added in the station and the section, increasing the construction difficulty. And after the train passes an active balise, before passing the next active balise, the updated temporary speed limit information within this range cannot be transmitted to the train in time, affecting the system availability; (2) If the temporary speed limit processing method of the CTCS-3 level train control system is adopted, the system requirements cannot be met in the area where the wireless network is not covered in the section; (3) If the temporary speed limit processing method of the CBTC system is adopted, the system requirements cannot be met in the area where the wireless network is not covered in the section.

[0030] Figure 1 The figure is a schematic flowchart of the method for processing temporary speed limits provided by an embodiment of the present disclosure. This embodiment of the present disclosure is applicable to the situation of temporary speed limit processing. This method can be executed by a processing device for temporary speed limits, and this device can be implemented in the form of software and / or hardware. Optionally, it is implemented by an electronic device, which can be a mobile terminal, a PC, a server, etc.

[0031] As Figure 1 shown, the method includes:

[0032] S110. The Temporary Speed Limit Server System (TSRS) sends the first temporary speed limit information to the ground device.

[0033] Among them, the ground device is used to receive the temporary speed limit information issued by the Temporary Speed Limit Server System (TSRS), and each station has a corresponding ground device. The first temporary speed limit information includes: main line temporary speed limit information and siding temporary speed limit information. In this embodiment, by splitting the first temporary speed limit information into main line temporary speed limit information and siding temporary speed limit information, it is convenient to store the first temporary speed limit information separately later.

[0034] Optionally, the Temporary Speed Limit Server System (TSRS) sending the first temporary speed limit information to the ground device includes: when the Temporary Speed Limit Server System (TSRS) issues the main line temporary speed limit information to the ground device, generating the first temporary speed limit information according to the main line temporary speed limit information number, ground device number, main line number, speed limit starting mileage marker, speed limit ending mileage marker, speed limit value, and speed limit reason information, and sending the first temporary speed limit information to the ground device; when the Temporary Speed Limit Server System (TSRS) issues the siding temporary speed limit information to the ground device, generating the first temporary speed limit information according to the siding temporary speed limit information number, ground device number, siding area number, speed limit value, and speed limit reason information, and sending the first temporary speed limit information to the ground device.

[0035] Among them, the main line temporary speed limit information number can be understood as the number of the temporary speed limit information itself. The main line number can be understood as the up-line number and the down-line number. The speed limit reasons include information such as wind, rain, snow, construction, sudden disasters, and bad environment. In this embodiment, when the temporary speed limit server system TSRS issues the main line temporary speed limit information to the ground equipment, it is divided into the main line temporary speed limit information and the siding temporary speed limit information. For the main line temporary speed limit information, the first temporary speed limit information is generated according to the main line temporary speed limit information number, the ground equipment number, the main line number, the speed limit starting mileage marker, the speed limit ending mileage marker, the speed limit value, and the speed limit reason information, and the first temporary speed limit information is issued to the ground equipment. For the siding temporary speed limit information, the first temporary speed limit information is generated according to the siding temporary speed limit information number, the ground equipment number, the siding area number, the speed limit value, and the speed limit reason information, and the first temporary speed limit information is issued to the ground equipment. In this embodiment, by specifically distinguishing the issuing methods of the main line temporary speed limit information and the siding temporary speed limit information, the first temporary speed limit information can be accurately sent to the ground equipment, and then the ground equipment can accurately identify the speed limit area corresponding to the first temporary speed limit information.

[0036] S120. The ground equipment stores the first temporary speed limit information in a set storage method.

[0037] Among them, the set storage methods include: the speed limit section combined with the speed limit offset method, and the speed limit starting and ending mileage marker method. In this embodiment, by storing the first temporary speed limit information in a different way according to the speed limit section combined with the speed limit offset method and the speed limit starting and ending mileage marker method, it is convenient to calculate the temporary speed limit information of the train's forward path according to different methods in the future.

[0038] Optionally, the ground equipment stores the first temporary speed limit information in a set storage method, including: when the ground equipment receives the main line temporary speed limit information, determining the section according to the main line temporary speed limit information; determining the station section and the section between stations according to the attributes of the section; if the section to which the main line temporary speed limit information belongs is the station section, determining the speed limit starting section number, the speed limit starting section offset, the speed limit ending section number, and the speed limit ending section offset according to the station section; storing the first temporary speed limit information in the order of the main line temporary speed limit information number, the speed limit value, the speed limit starting section number, the speed limit starting section offset, the speed limit ending section number, and the speed limit ending section offset; if the section to which the main line temporary speed limit information belongs is the section between stations, storing the first temporary speed limit information in the order of the main line temporary speed limit information number, the speed limit value, the main line number, the speed limit starting mileage marker, and the speed limit ending mileage marker.

[0039] Among them, the station section covers the wireless network, and the section between stations does not cover the wireless network. Figure 2Schematic diagram of the temporary speed limit range provided by the embodiment of the present invention. In Station A, the thinner straight lines (including double-headed arrows) in the figure represent the covered wireless communication area and also represent the in-station section, and the dotted lines represent the non-covered wireless communication area and also represent the section between stations. The thicker straight lines (including double-headed arrows) represent the temporary speed limit range, that is, the temporary speed limit range includes the in-station section and the section between stations. Among them, the temporary speed limit range of the main line is: the temporary speed limit range of the downlink main line of Station A starts from the mileage marker at the SN reverse approach signal of Station C and ends at the mileage marker at the X approach signal of Station B; the temporary speed limit range of the uplink main line starts from the mileage marker at the XN reverse approach signal of Station B and ends at the mileage marker at the S approach signal of Station C.

[0040] In this embodiment, if the section to which the temporary speed limit information of the main line belongs is the in-station section, the method of storing the first temporary speed limit information in sequence according to the main line temporary speed limit information number, speed limit value, speed limit starting section number, speed limit starting section offset, speed limit ending section number, and speed limit ending section offset is convenient for searching for the corresponding first temporary speed limit information according to different paths after the station route is handled.

[0041] In this embodiment, if the section to which the temporary speed limit information of the main line belongs is the section between stations, the method of storing the first temporary speed limit information in sequence according to the main line temporary speed limit information number, speed limit value, main line number, speed limit starting mileage marker, and speed limit ending mileage marker is convenient for the subsequent ground equipment to calculate the start and end points of the temporary speed limit before sending the temporary speed limit information to the train.

[0042] Optionally, the ground equipment stores the first temporary speed limit information in a set storage manner, including: when the ground equipment receives the siding temporary speed limit information, it determines the left offset and right offset of the speed limit section according to the siding temporary speed limit information; and stores the first temporary speed limit information in sequence according to the siding area number, left offset of the speed limit section, right offset of the speed limit section, and speed limit value.

[0043] In this embodiment, when the ground equipment receives the siding temporary speed limit information, the method of storing the first temporary speed limit information in sequence according to the siding area number, left offset of the speed limit section, right offset of the speed limit section, and speed limit value is convenient for searching for the temporary speed limit information within the path range according to the train running path when handling the siding route in the station.

[0044] For the siding temporary speed limit range, as Figure 3 shown, Figure 3This is a schematic diagram of the temporary speed limit range for the station siding provided by the embodiments of the present invention. The temporary speed limit range for the siding is as follows: The siding speed limit area is divided into Area 3 and Area 4 according to the station side range. The range of Area 3 of the siding is the side of 10DG, 3G, and the side of 9DG. The range of Area 4 of the siding is the side of 12DG, 4G, and the side of 11DG. Among them, 10DG, 3G, 4G, 11DG, etc. are all the names of track sections, and 4097, 4099, etc. are all the names of signal lights, and they are named by mileage markers. The signal light named with the letter "X" in the downlink route of Station A represents the signal light corresponding to the downlink, and the signal light named with the letter "S" in the uplink route of Station A represents the signal light corresponding to the uplink. Figure 3 Among them, the thickest line on the top represents Area 3 (siding area), and Area 3 includes the non-main line part of the downlink. The thickest line on the bottom represents Area 4 (siding area), and Area 4 includes the non-main line part of the uplink.

[0045] Exemplarily, taking Figure 3 as an example, the section between S3 and X3 is 3G. The total length of the 3G section is 1770 meters. 3G_1770 meters represents the speed limit section combined with the speed limit offset, 1770 meters represents the offset, the starting point is S3, and it also means that the entire 3G section is a speed limit area. If it is 3G_100 to 3G_1000 meters, it means that the area between 100 meters and 1000 meters is the speed limit area, and 3G_100 represents the left offset of the speed limit section, and 3G_1000 meters represents the right offset of the speed limit section.

[0046] S130. The ground equipment converts the stored first temporary speed limit information into second temporary speed limit information and sends the second temporary speed limit information to the train so that the train runs according to the second temporary speed limit information.

[0047] Among them, the first temporary speed limit information can be understood as all the temporary speed limit information of the station section and the section between stations. The second temporary speed limit information can be understood as the temporary speed limit information within the train's forward travel path during the actual operation of the train, and it is information that the train can recognize.

[0048] In this embodiment, based on the train position information, the second temporary speed limit information within the train's forward travel path can be calculated from the stored first temporary speed limit information, and the second temporary speed limit information is sent to the train through the wireless network.

[0049] Optionally, the ground equipment converts the stored first temporary speed limit information into second temporary speed limit information, including: obtaining the train position information; the train position information includes the train head position information and the train tail information; determining the train's forward travel path according to the train position information; determining the stored first temporary speed limit information within the forward travel path; converting the stored first temporary speed limit information into second temporary speed limit information in the form of the speed limit starting point, speed limit length, and speed limit value from the train head position information.

[0050] In this embodiment, the distribution method of the temporary speed limit in the station section and the section between stations is the same, that is, the distribution method of the temporary speed limit within the wireless coverage range and the distribution method of the temporary speed limit outside the wireless communication coverage range are the same. The distribution method of the temporary speed limit is: the position information of the train head to the starting point of the speed limit, the length of the speed limit, and the speed limit value.

[0051] Optionally, the ground equipment converts the stored first temporary speed limit information into second temporary speed limit information, including: if the forward running path passes through the station section, the stored first temporary speed limit information is used to calculate the second temporary speed limit information according to the speed limit section combined with the speed limit offset method, and the second temporary speed limit information is sent to the train; if the forward running path passes through the section between stations, the stored first temporary speed limit information is used to calculate the second temporary speed limit information according to the speed limit starting and ending mileage marker method, and the second temporary speed limit information is sent to the train.

[0052] In this embodiment, if the forward running path passes through the station section, the stored first temporary speed limit information is used to cumulatively calculate the second temporary speed limit information within the running path according to the speed limit section combined with the speed limit offset method, and the second temporary speed limit information is sent to the train through the wireless network. If the forward running path passes through the section between stations, the stored first temporary speed limit information is used to calculate the second temporary speed limit information according to the speed limit starting and ending mileage marker method, and the second temporary speed limit information is sent to the train. As Figure 4 shown, Figure 4 is another schematic diagram of the temporary speed limit provided by the embodiment of the present invention. Figure 4 The thick line part (gray) in it is the temporary speed limit of 25 km / h. Specifically, for train 3 in section 3G, there is a temporary speed limit of 25 km / h in the station section 3G and the approach from X3 to SN. There is a temporary speed limit of 25 km / h at the double thick line part between K410+900 and K420+600 in the section between stations ( Figure 4 the double thick line part). The second temporary speed limit information for the station section is: starting from the position information of the train head, to 3G_1770m, 9DG_200m, IAG_75m, with a length of 2045m and a speed limit value of 25 km / h. The second temporary speed limit information for the section between stations is: from the position information of the train head to the mileage marker of the starting point of the speed limit at K410+900, with a length of 700m and a speed limit value of 25 km / h.

[0053] Optionally, the train runs according to the second temporary speed limit information, including: the train calculates the braking curve according to the second temporary speed limit information; the train runs according to the braking curve.

[0054] In this embodiment, after receiving the second temporary speed limit information, the train calculates the braking curve according to the second temporary speed limit information to protect the safe operation of the train.

[0055] Figure 5Schematic diagram of temporary speed limit in a covered wireless network scenario provided by an embodiment of the present invention. Train 3 is running on section X2JG. There is a temporary speed limit of 25 km / h within the route from signal X to signal X1 at Station A ( Figure 5 the thick grey line part). Train 3 communicates bidirectionally with the ground equipment at Station A via a wireless network. The ground equipment calculates the second temporary speed limit information within the running path of Train 3 based on the train position information, the in-station route information, and the first temporary speed limit information, and sends it to Train 3 via wireless communication. After receiving the temporary speed limit information, Train 3 calculates the braking curve and monitors the safe operation of the train.

[0056] Figure 6 Schematic diagram of temporary speed limit in an uncovered wireless network scenario provided by an embodiment of the present invention. Train 3 is running on section IG. Station A handles the route from X1 to X. There is a section of temporary speed limit information of 25 km / h (the double thick grey line part) between Station A and Station B. Before leaving the station, Train 3 reports its position to the ground equipment. The ground equipment calculates the second temporary speed limit information within the running path based on the train position information and the first temporary speed limit information, and sends it to Train 3 via a wireless network. For the specific sending time, the second temporary speed limit information can be sent to Train 3 at any time when there is a wireless network within the station.

[0057] Figure 7 Schematic diagram of another temporary speed limit in an uncovered wireless network scenario provided by an embodiment of the present invention. When Train 3 runs into an area without a covered wireless network, the second temporary speed limit information sent by Station A can be used to calculate the braking curve to protect the safe operation of the train.

[0058] Furthermore, as Figure 2 shown, in this embodiment, it can solve the temporary speed limit handling method when the train travels from Station A to before the entrance of Station B at X or XN, and from Station A to before the entrance of Station C at SN or S. This method mainly extends the speed limit range of Station A to the entrances of X and XN at Station B, and to the entrances of S and SN at Station C. When the train is at Station A, it obtains the second temporary speed limit information within Station A via wireless communication, as well as the second temporary speed limit information for the area without a covered wireless network. When the train travels into the area where it cannot communicate with Station A, Station B, or Station C via a wireless network, the temporary speed limit information for the area received at Station A can be used to calculate the braking curve, thus ensuring the train's driving safety when it cannot obtain the temporary speed limit due to the lack of a covered wireless network in the area.

[0059] In the technical solution of the embodiment of the present disclosure, the first temporary speed limit information is sent by the Temporary Speed Limit Server System (TSRS) to the ground device; the ground device stores the first temporary speed limit information in a set storage manner; the ground device converts the stored first temporary speed limit information into the second temporary speed limit information and sends the second temporary speed limit information to the train, so that the train runs according to the second temporary speed limit information. In the embodiment of the present disclosure, by storing the first temporary speed limit information in a set storage manner, and the ground device converts the stored first temporary speed limit information into the second temporary speed limit information and sends the second temporary speed limit information to the train, it is possible to only cover the wireless network within the station, and in the scenario where the wireless network is not covered in the section. By communicating with the train under the condition that there is wireless network coverage within the station, the second temporary speed limit information within the train running path range within the station and the second temporary line speed limit information in the section are sent to the train, so as to realize that when the train runs in the section, under the condition of no wireless network coverage, the second temporary speed limit information received before leaving the station is used to control the safe operation of the train. Compared with covering the wireless network throughout the line or setting active balises throughout the line, the technical solution provided in this embodiment has a lower cost and stronger applicability.

[0060] Figure 8 It is a schematic structural diagram of a processing device for temporary speed limit provided by an embodiment of the present disclosure, as Figure 8 shown, the device includes: a first temporary speed limit information sending module 210, a storage module 220, and a conversion module 230.

[0061] The first temporary speed limit information sending module 210 is used for the Temporary Speed Limit Server System (TSRS) to send the first temporary speed limit information to the ground device;

[0062] The storage module 220 is used for the ground device to store the first temporary speed limit information in a set storage manner;

[0063] The conversion module 230 is used for the ground device to convert the stored first temporary speed limit information into the second temporary speed limit information and send the second temporary speed limit information to the train, so that the train runs according to the second temporary speed limit information.

[0064] The technical solution of the disclosed embodiment is to send the first temporary speed limit information to the ground device through the temporary speed limit server system TSRS of the first temporary speed limit information sending module; the ground device stores the first temporary speed limit information according to the set storage mode through the storage module; the ground device converts the stored first temporary speed limit information into the second temporary speed limit information through the conversion module, and sends the second temporary speed limit information to the train, so that the train runs according to the second temporary speed limit information. In the disclosed embodiment, by storing the first temporary speed limit information according to the set storage mode, the ground device converts the stored first temporary speed limit information into the second temporary speed limit information, and sends the second temporary speed limit information to the train, in the scenario where only the wireless network is covered in the station and the section is not covered by the wireless network, by communicating with the train under the condition of wireless network coverage in the station, the second temporary speed limit information within the running path of the train in the station and the second temporary line speed limit information in the section are sent to the train, so that the train can run in the section and use the second temporary speed limit information received before leaving the station to control the safe operation of the train under the condition of not covering the wireless network.
