Description

Technical Field

[0001] The present application relates to the field of railway train braking technology, and in particular to a method, device, equipment and medium for determining a standard pipe pressure of a train for train control on-board equipment. Background Art

[0002] The standard pipe pressure of trains on-board train control equipment on railways usually uses two fixed values ​​of 500kPa / 600kPa. The train control on-board equipment determines the value to be used according to the type of train mission (freight / passenger transport). This method of determining the standard pipe pressure of the train pipe according to the fixed value is relatively simple. It does not take into account the situation that before the train mission begins, the actual pressure value of the train pipe changes due to other objective factors, while the standard pipe pressure is not updated synchronously according to the actual situation. This can easily lead to errors in the calculation and use of the pressure reduction amount when the train control on-board equipment is monitoring, thereby reducing the safety of train operation. Summary of the invention

[0003] To solve the above problems, the present application provides a method, device, equipment and medium for determining the standard pipe pressure of a train control on-board equipment, which can improve the accuracy of the calculation and use of the pressure reduction amount by the train control on-board equipment, reduce the risk of train operation, and improve the safety of train driving.

[0004] To achieve the above objectives, this application adopts the following technical solutions: In a first aspect, the present invention provides a method for determining a train standard pipe pressure of a train control onboard equipment, comprising: The train standard pipe pressure determination state of the train control on-board equipment before and during train operation is divided into the initial state, the state of the moving train to be confirmed, and the state of the standard pipe pressure calibration; In the initial state, the determination parameters used in the process of determining the train standard pipe pressure of the train control on-board equipment are initialized, and the temporary set pressure initialized in the determination parameters is determined as the train standard pipe pressure of the train control on-board equipment; In the state of waiting for confirmation of the moving train, when the timing time of the first timer of the initial moving train in the determination parameter reaches or exceeds the maximum time of the timing time range, the actual pressure value of the current train pipe is determined as the train standard pipe pressure of the train control on-board equipment; In the standard pipe pressure calibration state, the train standard pipe pressure of the train control on-board equipment is recalibrated and determined.

[0005] Furthermore, the train standard pipe pressure determination state before the train starts for the first time after the train control on-board equipment is powered on is determined as the initial state.

[0006] Furthermore, the train standard pipe pressure determination state is determined from the start of timing of the first timer of the first train movement after the train movement for the first time until the maximum time of the timing time range of the first timer of the train movement for the first time, and is determined as the movement waiting for confirmation state.

[0007] Furthermore, the vehicle standard pipe pressure determination state when the timing time of the first timer of the first moving vehicle exceeds the maximum time of the timing time range is determined as the standard pipe pressure calibration state.

[0008] Furthermore, the initial state or the state of the moving train waiting for confirmation, the crew sets the parameters for starting the train and the train control on-board equipment enters the state of determining the standard pipe pressure of the train in the data control state, which is determined as the standard pipe pressure calibration state.

[0009] Furthermore, the train standard pipe pressure of the train control onboard equipment is recalibrated and determined, including: The actual pressure value of the current train pipe is obtained in real time. If the actual pressure value of the current train pipe is within the effective range of the train standard pipe pressure, the train standard pipe pressure of the train control on-board equipment is recalibrated and determined in combination with the second timer for calibrating the train standard pipe pressure and the floating range of the temporary fixed pressure.

[0010] Furthermore, in the process of determining the standard pipe pressure of the train control on-board equipment, each time the standard pipe pressure value of the train control on-board equipment is determined, if the determined standard pipe pressure of the train control on-board equipment exceeds the effective range of the train standard pipe pressure, a prompt will be given to the crew.

[0011] In a second aspect, the present invention further provides a train standard pipe pressure determination device for train control on-board equipment, comprising: A division module is used to divide the train standard pipe pressure determination state of the train control on-board equipment train standard pipe pressure determination process before and during the train operation into an initial state, a state of the train to be confirmed, and a standard pipe pressure calibration state; The first determination module is used to initialize the determination parameters used in the process of determining the train standard pipe pressure of the train control on-board equipment in the initial state, and determine the temporary set pressure initialized in the determination parameters as the train standard pipe pressure of the train control on-board equipment; The second determination module is used to determine the actual pressure value of the current train pipe as the train standard pipe pressure of the train control on-board equipment when the timing time of the first timer of the first train in the determination parameter reaches or exceeds the maximum time of the timing time range in the state of the train waiting to be confirmed; The calibration module is used to recalibrate and determine the standard pipe pressure of the train control on-board equipment in the standard pipe pressure calibration state.

[0012] In a third aspect, the present invention further provides an electronic device, comprising: a processor and a memory; The processor is coupled to the memory; The processor is used to read and execute the program or instructions stored in the memory, so that the device executes the method of the first aspect.

In the initial state, the train standard pipe pressure determination parameters of the train control on-board equipment are initialized. In the initial state and the state where the train has been moved and is awaiting confirmation, the train standard pipe pressure of the train control on-board equipment is determined based on the initialized determination parameters. In the standard pipe pressure calibration state, the train standard pipe pressure of the train control on-board equipment is recalibrated and determined, so that the determination of the train standard pipe pressure by the train control on-board equipment during operation is closer to the actual pressure value of the train pipe, thereby reducing usage errors, improving the accuracy of the calculation and use of the pressure reduction amount by the train control on-board equipment, reducing train operation risks, and improving train driving safety.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] One type of train brake is air brake, which controls the train brake device through air pressure. The control process can be briefly described as filling the train pipe with air through the main air cylinder, and using it after reaching a fixed value and the train has sufficient braking capacity. During the use process, the crew controls the exhaust of the train pipe through prescribed operations or control instructions from the train control on-board equipment, that is, exhausting the air in the train pipe to achieve train braking. When the brake is released, the train pipe is refilled with air to restore the train's braking capacity.

[0020] The train standard pipe pressure value of the train control on-board equipment is usually used to calculate the decompression amount and use the pressure-related control functions. The calculation formula of the decompression amount is as follows: Pressure reduction amount = determined train standard pipe pressure value of train control on-board equipment - current train pipe actual pressure value.

[0021] Before the train is required to perform a task, the train pipe pressure is checked and air is filled into the train pipe. After the train pipe pressure reaches a fixed value within the range of 500kPa / 600kPa and remains stable for a period of time, it is considered that the train pipe pressure has met the standard. 500kPa / 600kPa is determined as the standard train pipe pressure of the train control on-board equipment. Subsequent train control on-board equipment will participate in the calculation and use the determined value to achieve train braking or brake relief.

[0022] When determining the standard train pipe pressure of train control onboard equipment, the traditional method is to preset a fixed standard train pipe pressure of train control onboard equipment in advance. This method is relatively general and simple, and does not take into account the situation that the actual pressure value of the train pipe may change before actual use, such as: 1) The train pipes have been in use for a long time, and the interfaces are aging and worn. Problems with related accessories have not been discovered and updated in a timely manner; 2) There are cracks in the vehicle tube, which were not noticed during pressure testing and testing; 3) The train pipe is affected by the ambient temperature and humidity, and there are corrosion, thermal expansion and contraction, etc., and the pressure value cannot reach the expected effect; All of the above situations may lead to pressure leakage after the train control onboard equipment determines the standard pipe pressure when the train pipe pressure reaches a fixed value, so that there is a large deviation between the fixed value of the standard pipe pressure and the actual pressure value of the train pipe before the actual operation of the EMU, and the determined standard pipe pressure value is not updated in time, which has an adverse effect on the subsequent pressure calculation and functional control of the train control onboard equipment. Therefore, the technical solution of this application is used to solve the above problems.

[0023] Figure 1 This is a flow chart of a method for determining a train standard pipe pressure of a train control on-board device in an embodiment of the present application. As shown in the figure, the method includes: S101, dividing the train standard pipe pressure determination state of the train control on-board equipment in the train standard pipe pressure determination process before and during train operation into an initial state, a state where the train has been moved and is to be confirmed, and a standard pipe pressure calibration state; The train standard pipe pressure determination state before the train is used and before the train is first moved after the train control on-board equipment is powered on is determined as the initial state; the train standard pipe pressure determination state before the first timer of the train is started after the train is first moved and before the maximum time of the timing time range of the first timer of the train is reached is determined as the moved state waiting for confirmation; the train standard pipe pressure determination state when the timing time of the first timer of the train is more than the maximum time of the timing time range is determined as the standard pipe pressure calibration state.

[0024] S102, in the initial state, initializing the determination parameters used in the process of determining the train standard pipe pressure of the train control on-board equipment, and determining the temporary set pressure initialized in the determination parameters as the train standard pipe pressure of the train control on-board equipment; In the initial state, after the train control onboard equipment is powered on, the parameters used in the determination process of the train standard pipe pressure of the train control onboard equipment are initialized, including: the temporary set pressure of the train standard pipe pressure (such as: 500kPa), the floating range of the temporary set pressure (such as: temporary set pressure ±20kPa), the effective range of the train standard pipe pressure (such as: 450kPa-600kPa), the first timer for the first train movement (such as: the timing time range 0-t1, t1 is the maximum time of the timing time range), and the second timer for calibrating the train standard pipe pressure (such as: the timing time range 0-t2, t2 is the maximum time of the timing time range). The values ​​of the above parameters can be specified according to specific needs. When the train does not move, the initialized temporary set pressure is determined as the train standard pipe pressure of the train control onboard equipment and maintained unchanged, and the initial state of the train standard pipe pressure determination state is kept unchanged.

[0025] In the initial state, if the crew completes the parameter setting and performs start-up calibration, and the train control on-board equipment enters the data control state, the actual pressure value of the current train pipe is determined as the temporary set pressure of the train standard pipe pressure, and the updated temporary set pressure is determined as the train standard pipe pressure of the train control on-board equipment, and the train standard pipe pressure determination state of the train control on-board equipment entering the data control state is determined as the standard pipe pressure calibration state. The parameter setting in this application refers to the parameters set during start-up calibration, such as driver number 1 / 2, passenger / cargo type, speed level, marshaling information, section number, station number, etc., which are used to confirm the departure location, locomotive marshaling information, and retrieve the basic data location.

[0026] S103, in the state of waiting for confirmation of the moving train, when the timing time of the first timer of the initial moving train in the determination parameter reaches or exceeds the maximum time of the timing time range, the actual pressure value of the current train pipe is determined as the train standard pipe pressure of the train control on-board equipment; After the train is moved for the first time, the first timer of the first moving start timing, the train standard pipe pressure determination state enters the moved train waiting for confirmation state, and before the timing time of the first timer reaches the maximum time of the timing time range (the timing time of the first timer is within the timing time range), the initialized temporary set pressure value is determined as the train standard pipe pressure value of the train control on-board equipment, and maintained unchanged, and the moved train waiting for confirmation state of the train standard pipe pressure determination state is maintained unchanged. In the moved train waiting for confirmation state, if the timing time of the first timer reaches or exceeds the maximum time of the timing time range, the actual pressure value of the current train pipe is determined as the temporary set pressure of the train standard pipe pressure, and the updated temporary set pressure is determined as the train standard pipe pressure of the train control on-board equipment, and the train standard pipe pressure determination state when the timing time of the first timer exceeds the maximum time of the timing time range is determined as the standard pipe pressure calibration state, and the standard pipe pressure calibration state of the train standard pipe pressure determination state is maintained unchanged.

[0027] In the state of the train being moved but waiting for confirmation, if the crew completes the parameter setting and carries out the start-up benchmarking, the train control on-board equipment enters the data control state, then the actual pressure value of the current train pipe will be determined as the temporary set pressure of the train standard pipe pressure, and the updated temporary set pressure will be determined as the train standard pipe pressure of the train control on-board equipment, and the train standard pipe pressure determination state of the train control on-board equipment entering the data control state will be determined as the standard pipe pressure calibration state.

[0028] S104, in the standard pipe pressure calibration state, recalibrating and determining the train standard pipe pressure of the train control onboard equipment; After entering the standard pipe pressure calibration state, the train standard pipe pressure of the train control on-board equipment is recalibrated and determined, and the standard pipe pressure calibration state of the train standard pipe pressure determination state is kept unchanged.

[0029] Specifically, after entering the standard pipe pressure calibration state, the actual pressure value of the current train pipe is obtained in real time. If the actual pressure value of the current train pipe is not within the effective range of the train standard pipe pressure (such as 450kPa-600kPa), the temporary fixed pressure of the train standard pipe pressure and the train standard pipe pressure of the train control onboard equipment are not processed, and the temporary fixed pressure of the train standard pipe pressure and the train standard pipe pressure of the train control onboard equipment are maintained at the determined value; if the actual pressure value of the current train pipe is within the effective range of the train standard pipe pressure (such as 450kPa-600kPa), the temporary fixed pressure of the train standard pipe pressure and the train standard pipe pressure of the train control onboard equipment are recalibrated and determined in combination with the second timer for calibrating the train standard pipe pressure and the floating range of the temporary fixed pressure; the start flag value of the second timer for calibrating the train standard pipe pressure is false by default, and the start flag value is set to true after the start timing is started. When the start flag value of the second timer is true, it means that it is in the timing process of the second timer, and when the start flag value is false, it means that it is not in the timing process of the second timer. If it is not in the timing process of the second timer, determine whether the current actual train pipe pressure value is within the floating range of the temporary set pressure (such as: temporary set pressure ±20kPa). If it is not within the floating range of the temporary set pressure, the temporary set pressure of the train standard pipe pressure and the train standard pipe pressure of the train control on-board equipment will not be processed, and the temporary set pressure of the train standard pipe pressure and the train standard pipe pressure of the train control on-board equipment will maintain the determined values; if it is within the floating range of the temporary set pressure, the second timer for calibrating the train standard pipe pressure will be started and the timing will start, and the start flag value will be set to true, and the temporary set pressure of the train standard pipe pressure and the train standard pipe pressure of the train control on-board equipment will not be processed, and the temporary set pressure of the train standard pipe pressure and the train standard pipe pressure of the train control on-board equipment will maintain the determined values. If the second timer is in the timing process, determine whether the current actual train pipe pressure value is within the floating range of the temporary fixed pressure (such as: temporary fixed pressure ± 20kPa). If it is not within the floating range of the temporary fixed pressure, set the start flag value to false, and the second timer stops timing. When the above second timer start condition is met, restart the timing, and do not process the temporary fixed pressure of the train standard pipe pressure and the train standard pipe pressure of the train control on-board equipment. The temporary fixed pressure of the train standard pipe pressure and the train standard pipe pressure of the train control on-board equipment maintain the determined value; if it is within the floating range of the temporary fixed pressure If the time is within the range, it is determined whether the timing time of the second timer reaches or exceeds the maximum time of the timing time range. If it is not reached or exceeded, the temporary set pressure of the train standard pipe pressure and the train standard pipe pressure of the train control on-board equipment will not be processed, and the temporary set pressure of the train standard pipe pressure and the train standard pipe pressure of the train control on-board equipment will maintain the determined values; if it is reached or exceeded, the actual pressure value of the current train pipe will be determined as the temporary set pressure of the train standard pipe pressure, and the updated temporary set pressure will be determined as the train standard pipe pressure of the train control on-board equipment, completing the recalibration and determination of the train standard pipe pressure of the train control on-board equipment.

[0030] In the standard pipe pressure calibration state, if the crew completes the parameter setting and performs the start-up calibration (repeatable), the train control on-board equipment enters the data control state, then the actual pressure value of the current train pipe is determined as the temporary set pressure of the train standard pipe pressure, and the updated temporary set pressure is determined as the train standard pipe pressure of the train control on-board equipment, and the standard pipe pressure calibration state of the train standard pipe pressure determination state is kept unchanged In the above-mentioned initial state, the state confirmed by the moving vehicle, and the state of standard pipe pressure calibration, that is, the process of determining the standard pipe pressure of the train control on-board equipment, each time the standard pipe pressure value of the train control on-board equipment is determined, if the determined standard pipe pressure value of the train control on-board equipment is out of range (outside the effective range of the train standard pipe pressure), the crew will be prompted.

[0031] S105. Based on the determined train standard pipe pressure of the train control onboard equipment, control the train pipe to achieve train braking or brake relief.

[0032] According to the final determined train standard pipe pressure value of the train control on-board equipment, the decompression of the air in the train pipe is calculated, and the control command is generated according to the decompression. The control command includes the train braking command and the train braking relief command; the braking command controls the train pipe to discharge air to achieve train braking; the braking relief command controls the train pipe to re-fill air to restore the train braking capacity.

[0033] The technical solution in the embodiments of the present application has at least the following technical effects or advantages: The technical solution of the present application divides the train standard pipe pressure determination states of the train standard pipe pressure determination process of the train control on-board equipment before and during train operation into an initial state, a state where the train has been moved and is awaiting confirmation, and a standard pipe pressure calibration state. In the initial state, the train standard pipe pressure determination parameters of the train control on-board equipment are initialized. In the initial state and the state where the train has been moved and is awaiting confirmation, the train standard pipe pressure of the train control on-board equipment is determined based on the initialized determination parameters. In the standard pipe pressure calibration state, the train standard pipe pressure of the train control on-board equipment is recalibrated and determined, so that the determination of the train standard pipe pressure by the train control on-board equipment during operation is closer to the actual pressure value of the train pipe, thereby reducing usage errors, improving the accuracy of the calculation and use of the pressure reduction amount by the train control on-board equipment, reducing train operation risks, and improving train driving safety.
