Technical Field

The invention relates to a technology related to LKJ equipment, in particular to a method and a system for realizing automatic LKJ branch number acquisition by using station interlocking information.

Background

The LKJ2000 type monitoring device adopts a control mode (namely a vehicle-mounted control mode) that a vehicle-mounted computer stores ground line data in advance, the vehicle-mounted storage line data are sequentially called according to the position of a train during operation, the state is displayed according to a front signal, and the train running distance is calculated according to the train speed to generate a control mode curve. When the speed of the train exceeds the curve range of the control mode, the device carries out power cut, service brake and emergency brake control on the train, and the train is prevented from crossing a closed signal machine. After the device implements service braking, when the speed of the train is lower than the specified safe speed, the driver is allowed to relieve; for emergency braking control, a vehicle must be stopped before relief can be achieved. The processing mode under special conditions meets the requirements of technical regulations of railways. In order to ensure that the train stops reliably before the signal machine is closed, the calculation of the limiting speed adopts a real-time calculation method so as to meet the requirement of control precision. The calculation of the mode curve can adopt a cross-block subarea calculation mode according to the requirement of the running speed of the train, namely, a closed signal machine is used as a target point to calculate the continuous mode curves of the service brake and the emergency brake. Because the device has the interface function of information transmission with the ground and the processing function of transmitted information, a control scheme of combining vehicle-mounted data and ground transmitted information can be adopted in a section with ground information transmission. On one hand, the operation of crew members can be reduced, and the automation control degree is improved; meanwhile, the reliability and the safety of control can be improved. The information transmission mode can adopt a dot type transponder or a track circuit superposition mode and the like, and the transmission information comprises access information, station open access information, speed limit information, distance information and the like.

The LKJ2000 type train operation monitoring and recording device consists of a main case, a man-machine interaction unit (also called a screen display), a pressure sensor and a connecting cable. The monitoring device is matched with locomotive signal equipment, a speed sensor, a GPS receiving device, a local/supplementary switching device, a double-needle speedometer, a locomotive safety information comprehensive monitoring device (hereinafter referred to as TAX) and other equipment to form a train operation safety monitoring system.

The basic structure of LKJ2000 train operation monitoring and recording device is mainly a main machine box and two displays. The speed information comes from TQG15 or DF16 photoelectric speed sensors mounted on the locomotive wheel pair, and the basic configuration of the speed signals is two-channel (can be expanded to three-channel) if the two-channel speed signals are 90-phase different. The requirement of the anti-slip function of the device phase can be met. Under the condition of no phase anti-slip function, two-channel speed signals can be respectively obtained from two speed sensors. The cab signal information may be obtained from JT1-a (SJ93), JT1-B (SJ94) general cab signal devices (lighting conditions), or may be obtained by RS485/RS422 serial communication. The pressure detection not only detects the pressure of the train pipe, but also detects the pressure of a balance air cylinder and the pressure of a brake cylinder of the locomotive. The pressure signal of the equalizing air cylinder is used for feedback control to improve the control precision of the pressure reduction amount of the service brake, and the pressure signal of the brake cylinder is mainly used as a state recording basis when a single locomotive runs. The pressure sensor can adopt an TQG14 locomotive pressure transmitter. The pointer type speed indication can adopt a ZL type or EGZ3/8 type double-needle speedometer, the actual speed and the speed limiting pointer of the double-needle speedometer are driven by a device host, and the driving signal is a current signal of 0-20 mA. In case of shutdown of the device, it can be driven by the digital/analog converting box. The odometer indication of the I-end two-pin speedometer can be driven by the monitoring device, and in case of a digital/analog converter box being installed, also by the digital/analog converter box. The double-needle speedometer lighting power supply is a locomotive lighting power supply.

The railway shunting protection system consists of three parts: ground equipment, station positioning equipment and vehicle-mounted equipment.

The ground equipment mainly comprises a station yard information interface server, a communication server and the like arranged at each station, and a remote monitoring server and terminal equipment arranged at each railway bureau. The station yard information interface server of each station is mainly responsible for interfacing with the interlocking system, acquiring information such as access, track circuit, signal state and the like from the interlocking system, converting the information into a specific data format of the system and then sending the information to the system server; the server management terminal acquires information through the management server, so that management operation of system basic data is realized, and the station signal state, the station track information and the locomotive running state in the jurisdiction range are displayed in a centralized manner in real time. And the remote monitoring server of the railway bureau is used for remotely inquiring and displaying the state of the shunting operation safety protection system of each railway bureau.

The station positioning device mainly refers to a satellite differential base station and other devices arranged in a station. The method is mainly used for providing satellite differential data of a certain area (the radius is 30km) for the vehicle-mounted equipment.

And the vehicle-mounted equipment and the ground center equipment adopt public network mobile communication to exchange data in real time, receive differential data in real time and correct position errors, and realize accurate positioning of the locomotive (the positioning accuracy error is not more than 30 cm). The station yard state information sent by the ground system is received in real time through the data transmission radio station, information such as shunting route and the like is calculated in a coordinated mode, a calculation result is sent to the LKJ, and vehicle control protection is carried out through the LKJ.

The vehicle-mounted equipment mainly comprises a shunting protection host and a combined antenna. The combined antenna receives the ground interlocking broadcast information and then transmits the information to the radio plug-in unit on the shunting protection host machine through a feeder line.

The shunting protection host machine is internally composed of a power supply plug-in unit, a master control plug-in unit, an LKJ interface plug-in unit, a wireless communication and positioning plug-in unit and a radio station plug-in unit.

The master control plug-in unit communicates with the radio station plug-in unit through an RS232 serial interface to acquire station interlocking broadcast contents in real time. After the master control plug-in obtains the station interlocking information, corresponding state values such as a light display of a signal machine, occupation locking of a track section, positioning and reversing of a turnout and the like are given to each control in the station map data according to a mapping rule in the station map data. After the controls in the station yard graph data acquire the states, a train route can be quickly searched and obtained from any control along a determined direction by combining the incidence relation of each control. This provides for the implementation of automatic branch number acquisition.

The shunting protection system uses a computer interlocking system to acquire station interlocking information. The shunting protection system is provided with an interface machine at each station, and real-time station yard information is obtained from the interlocking operation representation machine through an RS-422 standard serial interface with photoelectric isolation. The defense regulating system only receives the data of the computer interlocking system in one way and does not affect the interlocking system.

The real-time performance of the station yard information source is guaranteed by a computer interlocking system, and meanwhile, protective measures such as a serial number, a real-time clock, CRC (cyclic redundancy check) and the like are added into interface communication data to guarantee the accuracy of received information.

At present, most of station grounds with shunting operation are provided with computer interlocking systems, and guarantee is provided for realizing automatic branch line number input of a shunting and defense system.

When a branch line exists in a line in front of the locomotive, a train operation monitoring device (LKJ for short) needs to retrieve basic data according to the serial number of the current branch line, acquire data information in front of the locomotive to calculate a braking curve, and control the operation of the locomotive.

Currently, the branch number for LKJ is manually entered by the driver. This mode of operation may have the condition of misdelivery and missed delivery. If the branch number is wrong, the traffic signal number and the line data length data used by the LKJ do not match the actual number. At the moment, the LKJ calculates a brake curve according to wrong data, so that the LKJ cannot prevent the locomotive from sending signals, jumping out of turnouts and running at an overspeed.

Fig. 2 is a flowchart illustrating an embodiment of a method for implementing LKJ automatic branch number acquisition using yard interlock information according to the present invention.

Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.

Before describing the flow of the method for automatically acquiring branch number by LKJ using yard interlock information according to the present invention, the basic principle of train branch transfer according to the present invention will be explained as follows.

Basic control data of the front branch line is stored in the LKJ system, and the basic control data comprises data of each branch line on the line (a branch line number of each branch line, a post-transfer traffic number, a line number after the branch line is transferred, an actual service line number corresponding to the branch line and the like). And storing station yard graph data in the shunting protection system, and recording the corresponding relation between each station boundary and the LKJ branch line.

And before the train enters or leaves the station, the LKJ inquires corresponding line data according to the current branch number. And according to the information such as the length corresponding to the current branch line, the speed limit condition, the current signal type and the like, the LKJ calculates to generate a corresponding brake curve, and the train is monitored to run at the speed not higher than the brake curve.

Conditions for LKJ requiring entry of branch number are: when the branch line exists in the current partition or the next partition of the locomotive, a branch line selection window is automatically popped up on the LKJ screen display, and at the moment, a crew member can manually input the number of the branch line.

The design principle of the LKJ for automatically acquiring the track number of the branch line is shown in fig. 1, and station yard map data of each station is stored in the shunting protection system in advance. The station yard graph data stores the position, the association relation, the speed limit information and the like of station yard signal equipment, and mainly comprises the following contents: signal machine, switch, track section, speed limit information, parking spot information. And filling branch data for station boundaries passed by the branches.

Taking station A as an example, the station A can be outbound through station boundary 1 when running according to a main line, and can be outbound through station boundary 2 when running according to a branch line 2.

The corresponding spur data are as follows:

when the train crosses the advance signal machine and is ready to enter the station A, the shunting protection system calls the station yard graph data of the station A according to the current station information sent by the LKJ, and sets vehicle-mounted station parameters according to the station information stored in the station yard graph data. And after the setting is finished, the shunting protection system receives real-time station interlocking information of the computer interlocking system through the radio station.

The shunting protection system searches station boundaries where the train passes according to the correlation among the locomotive position, station interlocking information and each control of the station yard graph data, and then confirms branch line numbers according to corresponding branch line data.

Referring to fig. 2, implementation steps of an embodiment of the method for implementing LKJ automatic branch number acquisition by using yard interlocking information according to the present invention are described in detail as follows.

Step 1: and after the train passes through the advance warning signal machine, the shunting protection system receives the current station information sent by the LKJ.

In step 1, if the station yard information is changed during the process of receiving the current station information, the operation of switching the station yard is performed.

Step 2: and searching the station yard graph data corresponding to the current station according to the station yard graph data reserved in the shunting protection system.

The station yard graph data stores the position, the association relation, the speed limit information and the like of station yard signal equipment, and mainly comprises the following contents: signal machine, turnout, track section, speed limit information (station track speed limit, electric control derailer and the like), and stop point information (fixed derailer, one-degree stop point, no-stop zone, contact net terminal, car stop, station boundary and the like). In the station yard graph, station yard signal equipment is divided into independent equipment called as controls according to the types of signal machines, turnouts and turnout-free track sections.

And step 3: after finding the station yard graph data corresponding to the current station, the shunting protection system sets vehicle-mounted radio station parameters including the receiving and transmitting frequency points and the baud rate of the radio station according to the radio station information in the station yard graph data.

And 4, step 4: and the shunting protection system receives real-time station interlocking information of the computer interlocking system through the radio station. Besides the broadcasting mode, the interlocking information of the station yard can be acquired through other network transmission modes or indirectly acquired through a TDCS/CTC system.

And 5: the shunting protection system searches station boundaries where the train passes according to the correlation among the locomotive position, station interlocking information and each control of the station yard graph data, and then confirms branch line numbers according to corresponding branch line data.

The specific implementation of step 5 is as follows.

Step 5-1: and judging the condition of train branch lines.

And when the branch information exists in the current partition or the next partition, the LKJ judges that the branch information is allowed to be input.

Step 5-2: and acquiring train route information.

And the shunting protection system determines the reverse state of each turnout according to the station interlocking information. The station yard graph data stores the association relation of each interlocking device, and after the control and the direction are determined, the next control has uniqueness.

After receiving the interlocking information of the station yard, the shunting protection system searches the relevant controls of each control in sequence along the running direction of the train by taking the current position of the locomotive as a starting point, and stops searching until the tail end of the access road is a station boundary or an earth block. And arranging each search result in sequence to obtain the train opening access information.

Step 5-3: and determining the number corresponding to the branch line.

And branch line number information corresponding to each station boundary is stored in the station yard graph data. And when the train route comprises a station boundary control, determining the current branch line number according to the branch line information associated with the station boundary in the station yard graph data.

In practical application, the display and prompt information of the system on the human-computer interaction interface are as follows: when the forward route contains branch information, the LKJ host sends an automatic branch number information popping-up instruction, and the LKJ screen display automatically pops up a 'branch number input window' after receiving the instruction. And after the LKJ screen display receives the front branch number sent by the shunting protection system, automatically filling the received branch number into a branch number input window.

The method for automatically acquiring the branch number of the invention has the following 2 abnormal conditions:

1) after the signal machine is announced in advance, the shunting protection system fails to acquire station chain information (station frequency point errors, ground interlocking equipment faults and the like in station map data), and at the moment, the turnout state cannot be known, and the branch line number search fails.

2) Station yard graph data are not stored in the shunting protection system, and the stored station yard graph data are wrong (mapping relation between station boundaries and branch line numbers is wrong, interlocking signal equipment is not matched with the actual situation, and the like), so that the searched branch line number is wrong.

When the branch number is failed to be acquired, the shunting protection system sends the branch number (for example, 0xFF) preset by the LKJ human-computer interaction unit, and a branch selection dialog box popped up by the LKJ human-computer interaction unit prompts 'asking for manual input', and reminds a crew member to manually input the branch number.

In addition to the above-described method, the present invention also discloses a system for implementing LKJ automatic branch number acquisition using yard interlock information, the system comprising a processor and a memory configured to store a series of computer-executable instructions and computer-accessible data associated with the series of computer-executable instructions.
