Description
Technical Field
The invention relates to the technical field of high-speed railways, in particular to a vehicle-mounted equipment processing system and method suitable for multiple train control ground systems.
Background
The vehicle-mounted equipment is a signal control equipment installed on a railway train, and plays a key role in ensuring the driving safety. The basic working principle is that according to line data stored in advance or acquired from ground equipment, the position of a train control target point (corresponding to a front closing signal machine, the tail end of a track section occupied by a front train or other dangerous points) is acquired from the ground equipment, and a speed limit curve is calculated to prevent the train from exceeding the allowable speed of the line, crossing the closed signal machine and the like, as shown in fig. 1. When the speed of the train is close to the speed limit curve, if the driver does not perform speed reduction operation, the vehicle-mounted equipment respectively gives out sound alarm prompt and outputs common brake for speed reduction and even emergency brake stop according to the difference value of the speed of the train and the speed limit curve so as to ensure the driving safety.
At present, three kinds of vehicle-mounted equipment are used in China, namely a train operation monitoring device (LKJ), CTCS-2 grade ATP and CTCS-3 grade ATP.
The LKJ stores the line data on the vehicle and selects the corresponding line data according to the input parameters of the driver. And acquiring the position of a vehicle control target point through the track circuit information. The highest running speed does not exceed 160 km/h.
The CTCS-2 level ATP does not store line data, realizes train positioning according to the transponder, acquires line data from the ground transponder, and acquires the position of a train control target point through a track circuit. The maximum running speed is 250 km/h.
The CTCS-3 ATP does not store line data, realizes train positioning according to the transponder, and acquires the line data and the position of a train control target point from the ground in a wireless mode. Meanwhile, the system also has the function of CTCS-2 level ATP, and a responder and a track circuit can be used for controlling the vehicle on a CTCS-2 level line. The maximum running speed is 350 km/h.
The line data stored by LKJ and the transponder data used by the CTCS-2 level/CTCS-3 level ATP are organized in a completely different manner and format.
Three railway line systems exist, namely CTCS-0, CTCS-2 and CTCS-3 grades, which respectively correspond to a common speed railway, a 250km/h high speed railway and a 350km/h high speed railway.
The ordinary speed railway only has a track circuit and does not have a transponder and a wireless device, so that the CTCS-2 ATP and the CTCS-3 ATP can not normally operate. For economic cost reasons, it is not possible for a conventional railway to be equipped with transponders and wireless devices like a high-speed railway.
Track circuits are equipment that currently exists on all railways. The ordinary speed railway and the high speed railway divide the line into a plurality of block partitions. The ground equipment can acquire whether a vehicle occupies each block subarea or not through the track circuit, and simultaneously can send the number of the front idle block subareas to the vehicle-mounted equipment through the track circuit. As shown in fig. 2, when the ground device knows that the block partition a is occupied by a vehicle, it transmits the track circuit information HU, U, LU, L2, L3, L4, and L5 codes, which indicate the number of block partitions that are free in front, to the block B, C, D, E, F, G, H, I via the track circuit. For example, when the train B enters the block H and receives code L4 from the track circuit, it is determined that 6 block blocks are free, and the train control target point is set at the end of the 6 th block ahead.
The vehicle-mounted equipment calculates a control curve, and also needs information such as the length of each block section, the allowable speed of a line, the gradient and the like, and the CTCS-0 level stores the data on the vehicle in advance. The CTCS-2 grade is that the train continuously acquires the data from the ground transponder in the running process. The CTCS-3 level acquires these data wirelessly.
The 250km/h motor train unit has more cross-common-speed railway running conditions and is provided with LKJ and CTCS-2 grade ATP. And the 350km/h motor train unit is only provided with CTCS-3 grade ATP, and the common locomotive is only provided with LKJ equipment.
The ordinary speed railway in China is not provided with matched CTCS-2/3 grade ground equipment, and the train can only be controlled in an LKJ mode. And the 350km/h motor train unit is only provided with CTCS-3 ATP and cannot normally run on a common-speed railway. With the continuous development of transportation networks in recent years, 350km/h motor train units also face the operation requirement of the cross-speed railway.
When the 250km/h motor train unit leaves a factory, two sets of LKJ and ATP equipment are installed at the same time. The two sets of equipment are provided with respective cabinets, the driving table is provided with respective displays for displaying a human-computer interface unit display, the wheels are provided with respective speed sensors for measuring speed, the occupied space is large,
and the installation of LKJ equipment is not considered when the 350km/h motor train unit leaves the factory. If an independent cabinet and peripheral equipment of the LKJ are installed on the 350km/h motor train unit according to the mode of the 250km/h motor train unit, the speed sensor of the LKJ is additionally installed on wheels, and an LKJ display screen is additionally installed in a driver cab, the motor train unit operated on site needs to be greatly improved.
In the prior art, referring to fig. 3, books: CTCS-2-class train operation control system using book-train control on-board equipment (CTCS 2-200C), chinese railway press, book number: ISBN 978-7-113-13047-3, page 6, fig. 2-1, discloses a CTCS-2 level train control system vehicle-mounted device, which gives the current 250km/h motor train unit LKJ installation scheme, and the LKJ has an independent display used for displaying a human-computer interface unit DMI, a speed sensor and a train independent interface. Journal articles: a train control system feasible scheme of a 350 km/h-grade motor train unit suitable for normal railway line operation considers [ J ] locomotive electric transmission, 2019(06):15-17, and provides a scheme of additionally arranging LKJ on the 350 km/h-grade motor train unit. The scheme is based on LKJ-15 type equipment of a safety computer platform, and LKJ still has an independent DMI, a speed sensor and a working condition input interface and a brake output interface which are independent of a train. The invention patent application: CN202011354225.9 discloses that LKJ's control record plug-in unit puts the ATP on-vehicle host computer, accomplishes the accuse car function of ordinary speed railway by LKJ control record plug-in unit. The scheme can solve the problem that the 350km/h motor train unit runs on a common-speed railway, but if a new ground standard exists in the future, new vehicle-mounted plug-ins are continuously added, and the space requirement is increased. The invention patent application: CN 202011484204.9, which discloses an automatic switching method and system for train operation modes, wherein under the condition that it is determined that a train runs in a common management area, ground equipment information uploaded by a ground responder is received; determining a target operation mode of the train according to the ground equipment information; the current operation system of the train is switched to the target operation system, so that the compatibility of various ground track systems in the same vehicle-mounted equipment is realized. In the above application, the vehicle-mounted device is provided with a plurality of different interface modules, each module is pre-programmed with corresponding operation control software, when the vehicle-mounted device operates to a ground section with a corresponding system, the corresponding interface module operation control software is called to control a train, when the ground section has a plurality of systems, the scheme needs to be provided with a plurality of interface modules, and the requirement on installation space is high. In addition, no solution is provided for the existing on-site motor train unit vehicle-mounted equipment, and the system architecture of the existing vehicle-mounted equipment is adjusted according to the scheme, so that the implementation is difficult.
In view of the above-mentioned defects in the prior art, how to convert the line data of the ordinary speed railway into a transponder message format that can be processed by the current vehicle-mounted device, and send the transponder message format to the vehicle-mounted device by using the existing data channel, so that the vehicle-mounted device can normally operate on the ordinary speed line, is a problem to be solved in the present technical field.

The invention can also be used for expanding and adapting the vehicle-mounted equipment to other train control ground systems.
In existing on-board devices, the host unit and the transponder transmission module are directly connected. In a specific embodiment of the invention, the connection between the host unit and the transponder transmission module is disconnected, and a train control data conversion device is added between the host unit and the transponder transmission module. The basic working principle of the invention is that when the lines of 250km/h and 350km/h run, the change-over switch is arranged at the node of the transponder transmission module, the host unit of the vehicle-mounted equipment uses the ground data provided by the transponder transmission module to carry out operation, and the control logic is consistent with the existing logic. When the vehicle runs on a common speed line, a driver places a change-over switch at a node of the column control data conversion device, and the vehicle-mounted equipment host unit performs operation and vehicle control by using ground data provided by the column control data conversion device. The data format generated by the train control data conversion device is a transponder format, and because the transponder formats of CTCS-2 level and CTCS-3 level vehicle-mounted equipment can be processed, the software change of a host unit of the vehicle-mounted equipment can be reduced.
Referring to fig. 4, a specific embodiment of the present invention is a processing system for a vehicle-mounted device suitable for multiple train control ground systems, which specifically includes: the system comprises a vehicle-mounted equipment host unit, a train control data conversion device and a transponder transmission module. And the vehicle-mounted equipment host unit is sequentially connected with the train control data conversion device and the transponder transmission module.

And if the data version of the USB flash disk is inconsistent with the data version stored in the device, the column control data conversion device updates the file to the data storage position of the corresponding system. In the maintenance mode, the train control data conversion device is not communicated with the main control unit of the vehicle-mounted equipment, and different working steps are displayed through a panel indicator light. And the maintenance personnel judge that the data updating is finished through the indicator light, unplug the USB flash disk and restart the USB flash disk, and the train control data conversion device enters a working state and uses the updated data.
The wireless communication module realizes communication and data decryption operation with the ground data reloading system through the antenna, and obtains the latest ground data for remote data updating; when the train control data conversion device is in a working state and a data upgrading command is wirelessly received through the wireless communication module, a data upgrading request is sent to the human-computer interaction interface DMI through the vehicle-mounted main control unit; and after the confirmation of maintenance personnel or drivers, the train control data conversion device automatically updates the data.
In the data updating process, the train control data conversion device cannot send ground data to the host unit of the vehicle-mounted equipment, and after the data updating is completed, a data updating completion prompt is sent to the human-computer interaction interface DMI through the main control unit of the vehicle-mounted equipment. And after the power is turned on again, the train control data conversion device uses the updated data.
Another embodiment of the present invention is a method for processing a vehicle-mounted device applicable to multiple train control ground systems, which is applied to the vehicle-mounted device processing system applicable to multiple train control ground systems described in the previous embodiment. The method specifically comprises the following steps:

When operating on a high-speed railway, the driver needs to select the line level CTCS-2/3 on the human-computer interaction interface DMI and place the selector switch at the node on one side of the transponder transmission module. When the railway runs at the ordinary speed, a driver needs to place a change-over switch at a node on one side of the train control data conversion device, select the CTCS-0 level in the DMI and input a departure data traffic number and a station number.
And when the vehicle-mounted equipment host unit receives a CTCS-0-level command of a DMI (human-computer interaction interface), only using a CTCS-0-level responder message generated by the train control data conversion device. And when the vehicle-mounted equipment host unit receives a CTCS-2/3 level command of a human-computer interaction interface DMI, only using the responder message sent by the responder transmission module. The message type is judged through a special identifier. If the received transponder message identification is inconsistent with the selection command of the DMI, the abnormal conditions that the line grade selected by the human-computer interaction interface DMI is inconsistent with the change-over switch, the change-over switch fails and the like occur, and at this time, the host unit of the vehicle-mounted equipment actively outputs a braking command to stop the vehicle so as to ensure the safety.
S4, after receiving a line level CTCS-0 level command from a human-computer interaction interface DMI, the host unit of the vehicle-mounted equipment sends an initialization command to the column control data conversion device, wherein the initialization command comprises a column control ground system CTCS-0, the departure data traffic route number and a station number; and the train control data conversion device searches a line on which the train needs to run in pre-stored data and searches a starting point of the line according to the station number.
If the train control data conversion device is searched successfully, replying search success information to the vehicle-mounted equipment host unit, and attaching the searched line name, station name and data version number; the vehicle-mounted equipment host unit sends the information to the human-computer interaction program DMI for confirmation of a driver, after the driver confirms the information, the vehicle-mounted equipment host unit sends the confirmation information to the train control data conversion device, and the train control data conversion device continues to execute the subsequent steps only after receiving the confirmation information. If the driver finds the input wrong, the input can be re-input, and if the data version is wrong, maintenance personnel needs to be informed to update the data or take other emergency operation.
If the search fails, the train control data conversion device replies search failure information to the vehicle-mounted equipment host unit, and failure reasons are attached, wherein the failure reasons comprise equipment failure, failure of verification of prestored data or data integrity without corresponding modes, and failure of line number/station number; the vehicle-mounted equipment host unit sends the information to the man-machine interaction program DMI for display, if a driver finds that the input is wrong, the information is input again, and if other reasons are found, maintenance personnel need to be informed to repair, update data or take other emergency operations.
S5, the on-board equipment host unit periodically sends train running speed and accumulated running distance to the train control data conversion device; the train control data conversion device judges the position of the train according to the initial position and the accumulated running distance of the train, converts the line data of 8 front annunciators into a transponder message format when passing through one annunciator and sends the transponder message format to the on-board equipment host unit; and the on-board equipment host unit performs logical operation on the train by combining the track circuit information and the received line data.
When the train control data conversion device judges that a bifurcation point exists in front of the train, such as entering different station tracks and branches, the end point of the data is only sent to the position of the bifurcation point, and a station track and branch input request is sent to the host unit of the vehicle-mounted equipment. The host unit of the vehicle-mounted equipment displays the input request through a human-computer interaction interface DMI, and after a driver checks the situation of a front line and inputs a correct station track or branch line, the host unit of the vehicle-mounted equipment sends information to the train control data conversion device. And the train control data conversion device selects corresponding line data extension according to the driver input information, converts the line data of the front 8-frame annunciator into a transponder message format and sends the transponder message format to the on-board equipment host unit. If the train control data conversion device does not receive the input information of the driver within the specified time or does not find the corresponding stock track or branch line according to the input information, the driver is prompted again through the human-computer interaction interface DMI, and the end point of the data is still maintained to the position of the branch point.
