Description

Technical Field

[0002] In the current locomotive technology solution, each driver's cab is only equipped with one brake screen. When the only brake screen fails, it will affect the normal operation of the locomotive. Therefore, it is necessary to configure at least two brake screens for each driver's cab for redundancy.

[0003] The brake screen has the functions of setting the brake status, triggering brake performance self-test, and calibrating the sensors inside the brake. The use of multiple brake screens may lead to conflicts in the operations of each brake screen, and multiple instructions triggered by the brake screen may exist at the same time, resulting in lower driving safety of the locomotive.

[0076] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only 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.

[0077] In this application, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The terms "comprise", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the statement "comprising a ..." do not exclude the presence of other identical elements in the process, method, article or equipment including the elements.

[0078] In the current locomotive technology solution, each driver's cab is only equipped with one brake screen. When the only brake screen fails, it will affect the normal operation of the locomotive. Therefore, it is necessary to configure at least two brake screens for each driver's cab for redundancy.

[0079] The brake screen has the functions of setting the brake status, triggering the brake performance self-test, and calibrating the sensors inside the brake. Each function is mutually exclusive to a certain extent: for example, calibration is prohibited during the self-test process. The use of multiple brake screens may lead to conflicts in the operation of each brake screen, and multiple instructions triggered by the brake screen may exist at the same time, resulting in low driving safety of the locomotive.

[0080] In order to solve the operational conflicts between the brake screens in the prior art and how to handle the situation where multiple instructions exist at the same time to ensure the driving safety of the locomotive, the embodiment of the present application provides a mutually exclusive control method for a brake screen and a brake motor, which is applied to a mutually exclusive control system, which includes multiple brake screens, a brake motor, and a central control unit (CCU) for managing the communication between the multiple brake screens and the brake motor. The display state of the target brake screen is obtained, and the display state includes any one of the setting interface, the self-test interface, and the calibration interface. The target brake screen is any brake screen among the multiple brake screens. The buttons of the conflicting interface that is mutually exclusive with the display state on the non-target brake screen are hidden, and the non-target brake screen is the other brake screens among the multiple brake screens except the target brake screen. The control instruction triggered by the display state of the target brake screen is obtained, and the control instruction includes any one of the setting instruction, the self-test instruction, and the calibration instruction, wherein the setting instruction is used to instruct the brake motor to perform a state setting, the self-test instruction is used to instruct the brake motor to perform a performance self-test, and the calibration instruction is used to instruct the brake motor to perform a sensor calibration. When the control instruction is used to control the brake motor, the instruction that is mutually exclusive with the control instruction is limited. In this way, through the mutually exclusive design of the brake screen's interface functions and the brake motor's command response, operational conflicts between the brake screens can be avoided, the possibility of misoperation can be eliminated from the design perspective, and other commands received by the response brake motor at the same time can be limited, thereby ensuring the driving safety of the locomotive and improving driving safety.

[0081] In order to facilitate understanding of the technical solution provided in the embodiment of the present application, a mutually exclusive control method and system for a brake screen and a brake motor provided in the embodiment of the present application are described below in conjunction with the accompanying drawings.

[0082] The mutually exclusive control method of a brake screen and a brake motor provided in an embodiment of the present application can be applied to a mutually exclusive control system, which includes multiple brake screens, brake motors, and a central control unit, wherein each brake screen and brake motor communicates with the central control unit through a network, and the central control unit is used to manage the communication between the multiple brake screens and brake motors. Figure 1 , Figure 1 A schematic flow chart of a mutually exclusive control method of a brake screen and a brake motor provided in an embodiment of the present application, the method specifically includes S101-S104.

[0083] S101: Acquire a display state of a target brake screen, where the display state includes any one of a setting interface, a self-checking interface, and a calibration interface, and the target brake screen is any one of a plurality of brake screens.

[0084] The brake screen has three horizontal sub-interfaces: setting interface, self-test interface and calibration interface. Click the [Enter setting interface] button, [Enter self-test interface] button and [Enter calibration interface] button to enter the corresponding interface and select the corresponding operation instruction.

[0085] The setting interface is used to set the brake status, including local / single / compensation, one-time relief / stage relief, air supply / no air supply, constant pressure, etc. The self-test interface is used to trigger the brake performance self-test. The calibration interface is used to calibrate the sensors inside the brake, including various pressure sensors and flow sensors.

[0086] See also Figure 2 , Figure 2 A mutually exclusive control system configuration and network topology diagram provided in an embodiment of the present application. The brake screen may include a master brake screen (brake screens 1 to 4) and a slave brake screen (brake screens 5 to 8). The slave indicates that there is no driver on duty. If it is a slave brake screen 5 to 8, the [Enter setting interface] button, [Enter self-test interface] button, and [Enter calibration interface] button are hidden.

[0087] It should be noted that the brake screens involved in the embodiments of the present application are all main control end brake screens.

[0088] Among multiple brake screens, if any of the settings interface, self-test interface and calibration interface is triggered on any brake screen, then this brake screen is the target brake screen, and the display status of the target brake screen will be updated from the main page to the corresponding interface.

[0089] S102: hiding buttons of conflicting interfaces that are mutually exclusive with the display state on a non-target braking screen, wherein the non-target braking screen is other braking screens among the plurality of braking screens except the target braking screen.

[0090] In the mutually exclusive design of the brake screen's interface functions, the calibration interface is mutually exclusive with the other two interface functions; only one calibration interface is allowed to exist at the same time; only one interface is allowed to exist on a brake screen at the same time, and the setting interface and self-test interface are allowed to exist at the same time on different brake screens; during the performance self-test, the settings interface and the "calibration page" functions are shielded.

[0091] 1. The calibration interface and the other two interfaces are mutually exclusive.

[0092] When calibrating a sensor, some setting functions of the brake may be abnormal. For example, when calibrating the equalizing air cylinder pressure sensor, the constant pressure setting function is abnormal because the object of the constant pressure setting is the equalizing air cylinder. Some self-checking steps of the brake may be abnormal. For example, during the self-checking, the calibration changes the upper or lower limit of the train pipe pressure sensor, and the self-check of the train pipe pressure change rate may be abnormal. Therefore, it is necessary to limit the calibration interface to be mutually exclusive with the other two interface functions.

[0093] In one possible implementation, if the display state of the target brake screen is the calibration interface, the signal of "being at the calibration interface flag position" is broadcast to other brake screens (non-target brake screens) through the CCU. After receiving the signal, other brake screens hide the trigger buttons corresponding to the setting interface and self-test interface that are mutually exclusive with the calibration interface, namely, the [Enter setting interface] button and the [Enter self-test interface] button.

[0094] In one possible implementation, if the display state of the target brake screen is the setting interface, the signal of "located at the setting interface flag" is broadcast to other brake screens (non-target brake screens) through the CCU. After receiving the signal, other brake screens hide the trigger button corresponding to the calibration interface that is mutually exclusive with the setting interface, that is, hide the [Enter calibration interface] button, and hide the function button corresponding to the self-test interface. The setting interface and self-test interface of other brake screens are not hidden, that is, the [Enter setting interface] button and the [Enter self-test interface] button can still be triggered.

[0095] After broadcasting the signal "located at the setting interface flag position", the function buttons under the setting interface and self-test interface are not hidden first, that is, any brake screen can be operated to set the brake and trigger the brake performance self-test, until a brake screen triggers the brake setting (the brake broadcasts the "brake is setting the flag position" signal to all brake screens), and then hide the function buttons under the setting interface and self-test interface of other brake screens.

[0096] In one possible implementation, if the display state of the target brake screen is the self-test interface, the signal "located at the self-test interface flag" is broadcast to other brake screens (non-target brake screens) through the CCU. After receiving the signal, other brake screens hide the trigger button corresponding to the calibration interface that is mutually exclusive with the setting interface, that is, hide the [Enter calibration interface] button, and hide the function button corresponding to the setting interface. The setting interface and self-test interface of other brake screens are not hidden, that is, the [Enter setting interface] button and the [Enter self-test interface] button can still be triggered.

[0097] After broadcasting the model "located at the self-test interface flag position", the function buttons under the setting interface and self-test interface are not hidden first, that is, any brake screen can be operated to set the brake and trigger the brake performance self-test, until a brake screen triggers the brake performance self-test (the brake broadcasts the "brake is in self-test flag position" signal to all brake screens), and then hide the function buttons under other brake screen setting interfaces and self-test interfaces.

[0098] 2. Only one calibration interface is allowed at the same time.

[0099] There are many sensors in the brake machine. Taking the pressure sensor as an example, the calibration process of each pressure sensor is basically the same. For example, first select the upper limit or lower limit of calibration (calibration limit), input the pressure value (measurement data) measured by the external pressure gauge, the actual data read by the brake machine, and the brake machine calibrates the pressure sensor according to the above data. Therefore, the function buttons under the calibration interface are also basically the same. The brake machine needs to know which pressure sensor calibration interface the brake screen is located in before it can specifically execute the key instructions under the calibration interface. If there are multiple calibration interfaces at the same time and the calibration objects are different, it is equivalent to calibrating different sensors at the same time, which is difficult to achieve in operation. For example, when the train pipe pressure is at the upper limit and the brake cylinder pressure is at the lower limit, theoretically they can be calibrated at the same time, but the requirements for the operator are high, so it needs to be handled simply, limiting that only one calibration interface is allowed at the same time.

[0100] If any brake screen among brake screens 1 to 4 on the master end is already in the calibration interface, the "calibration interface flag" signal is broadcast to other brake screens. After receiving the signal, the other brake screens on the master end hide the [Enter calibration interface] button.

[0101] 3. Only one interface is allowed to exist on a brake screen at the same time, and the setting interface and self-test interface are allowed to exist on different brake screens at the same time.

[0102] At the same time, only one interface is allowed to exist on a brake screen, that is, two or more interfaces cannot exist on the brake screen at the same time.

[0103] The setting interface and the self-test interface have a viewing function, and the brake machine status and system status can be viewed in the setting interface at the same time, and the last self-test result can be viewed in the self-test interface. Therefore, the setting interface and the self-test interface are allowed to exist at the same time, specifically: different brake screens among multiple brake screens are allowed to be in the setting interface and the self-test interface at the same time, for example, brake screen 1 is in the setting interface, and brake screen 2 is in the self-test interface. It is also allowed that multiple brake screens are in the setting interface or the self-test interface at the same time, for example, brake screen 1 and brake screen 2 are both in the setting interface, or brake screen 1 and brake screen 2 are both in the self-test interface.

[0104] No setting instructions will be issued when entering the setting interface. You also need to click, for example, the [Local / Single / Supplementary Machine Switch] button, the [One-time Relief / Stage Relief Switch] button, the [Supplementary Air / No Supplementary Air Switch] button, etc. to trigger the execution of the brake state setting; no self-test instructions will be issued when entering the self-test interface. You also need to click the [Start] button to trigger the brake to perform a self-test.

[0105] The settings and self-test interfaces can be viewed at the same time, and the interface functions are relatively mutually exclusive. For example, when the brake is self-testing, you can view the settings interface and self-test interface, but you cannot select the corresponding function. For example, when the brake is not self-testing, you can view the settings interface and self-test interface, and you can select the corresponding function on any brake screen.

[0106] When you need to check the brake status and / or the last self-test results, you can click the trigger button of the setting interface or the trigger button of the self-test interface on multiple brake screens to enter the setting interface or the self-test interface; trigger the view button of at least one of the setting interface and the self-test interface to check the brake status and / or the last self-test results.

[0107] 4. The function of shielding the setting interface and "calibration page" during the performance self-check process.

[0108] Both the performance self-check and sensor calibration are processes that take some time to complete. Therefore, during the performance self-check, the sensor calibration cannot be performed simultaneously.

[0109] The self-check process automatically triggers the performance check of the brake according to the preset process. It is meaningless to set the brake state during the process. For example, the local / single state, "air supply / no air supply" state, etc. will be automatically switched during the self-check process. The brake state will be automatically switched after it is set.

[0110] Therefore, the functions of the setting interface and the calibration interface are shielded during the brake performance self-test process.

[0111] In one possible implementation, if the brake motor is in the process of self-testing performance, the "brake motor is self-testing flag" signal is uploaded to each brake screen (master control end brake screen 1 to 4). After each brake screen receives the signal, the [Enter calibration interface] button and the corresponding function buttons of the setting interface are hidden.

[0112] S103: Obtain a control instruction triggered by a display state of the target brake screen, the control instruction comprising any one of a setting instruction, a self-test instruction and a calibration instruction, wherein the setting instruction is used to instruct to perform a state setting on the brake motor, the self-test instruction is used to instruct to perform a performance self-test on the brake motor, and the calibration instruction is used to instruct to perform a sensor calibration on the brake motor.

[0113] The brake motor executes the corresponding command in the display state, that is, if the brake motor is not in the setting interface, self-test interface or calibration interface (the "setting / self-test / calibration interface flag" signal is not received), the brake motor does not respond to the setting / self-test / calibration command.

[0114] The target brake screen triggers corresponding control instructions in its display state, that is, triggers setting instructions in the setting interface, triggers self-test instructions in the self-test interface, and triggers calibration instructions in the calibration interface.

[0115] S104: When using the control command to control the brake, limiting the response to commands that are mutually exclusive with the control command.

[0116] The aforementioned steps S101-S102 are mutually exclusive functions of the brake screen interface. However, network communication failure or software operation abnormality may cause the brake screen interface function to be mutually exclusive abnormal. At this time, as a safety redundancy in control, the brake machine must also prohibit simultaneous setting, self-checking and calibration.

[0117] After the brake responds to the control instruction and performs the corresponding operation, the instructions mutually exclusive with the control instruction are limited to respond. Specifically, if the display state is the calibration interface, the control instruction is the calibration instruction, and the instructions mutually exclusive with the control instruction are limited to respond, including: setting instructions and self-test instructions that are mutually exclusive with the calibration instruction. If the display state is the setting interface, the control instruction is the setting instruction, and the instructions mutually exclusive with the control instruction are limited to respond, including: calibration instructions and self-test instructions that are mutually exclusive with the setting instruction. If the display state is the self-test interface, the control instruction is the self-test instruction, and the instructions mutually exclusive with the control instruction are limited to respond, including: setting instructions and calibration instructions that are mutually exclusive with the self-test instruction.

[0118] The calibration interface has sub-interfaces, such as "brake cylinder pressure sensor calibration interface", "total wind pressure sensor calibration interface", etc., to distinguish which target sensor is calibrated. The target sensor is determined by the operator, and the embodiments of the present application do not limit this. It should be noted that there is no priority definition for sensor calibration, and the operator calibrates the sensor that needs to be calibrated according to actual needs.

[0119] In one possible implementation, if the display state is a calibration interface and the control instruction is a calibration instruction, when executing the calibration instruction, it is also necessary to predetermine a target sensor calibration sub-interface, and only one target sensor calibration sub-interface is allowed to exist at the same time.

[0120] In the calibration interface, determine the target sensor calibration sub-interface. If there is one target sensor calibration sub-interface, obtain the calibration limit, measurement data and actual data; control the brake to respond to the calibration instruction, and complete the calibration of the target sensor according to the calibration limit, measurement data and actual data. If there are multiple target sensor calibration sub-interfaces, control the brake not to respond to the calibration instruction and exit the calibration interface.

[0121] On the basis of the mutually exclusive design of the interface functions of the brake screen, the mutually exclusive design of the command response of the brake motor is added. The redundant design of the control can avoid the difficulty of locomotive driving after the abnormality of the mutual exclusion of the interface functions of the brake screen occurs, and can better ensure the driving safety of the locomotive.

[0122] Based on the contents of the above steps S101-S104, it can be known that the display state of the target brake screen is obtained, and the display state includes any one of the setting interface, the self-test interface and the calibration interface, and the target brake screen is any brake screen among the multiple brake screens. The buttons of the conflicting interface mutually exclusive with the display state on the non-target brake screen are hidden, and the non-target brake screen is the other brake screens among the multiple brake screens except the target brake screen. The control instructions triggered by the display state of the target brake screen are obtained, and the control instructions include any one of the setting instructions, the self-test instructions and the calibration instructions, wherein the setting instructions are used to instruct the brake machine to perform state setting, the self-test instructions are used to instruct the brake machine to perform performance self-test, and the calibration instructions are used to instruct the brake machine to perform sensor calibration. When the control instructions are used to control the brake machine, the instructions that are mutually exclusive with the control instructions are limited to respond. In this way, through the mutually exclusive design of the interface functions of the brake screen and the mutually exclusive design of the command response of the brake machine, the operation conflicts between the brake screens are avoided, and the response to other instructions received by the brake machine at the same time is limited, which can ensure the driving safety of the locomotive and improve the driving safety.

[0123] In another embodiment of the present application, a network communication failure or abnormal software operation is described.

[0124] When the brake motor is in the calibration process, if the target brake screen has a "calibration interface flag" signal, it means that the brake motor responds to the calibration command but does not respond to the setting command and self-test command.

[0125] If the calibration interface and the setting interface exist simultaneously in multiple brake screens, that is, the "calibration interface flag" signal and the "setting interface flag" signal exist simultaneously, the brake motor is driven to automatically exit calibration. After this step, the setting instruction triggered by the setting interface can be obtained, and the brake motor is executed to set the state in response to the setting instruction.

[0126] If the calibration interface and the self-test interface exist simultaneously in the plurality of brake screens, that is, the "calibration interface flag" signal and the "self-test interface flag" signal exist simultaneously, the drive brake automatically exits the calibration, and the control brake does not respond to the self-test instruction and exits the self-test interface.

[0127] If the "calibration interface flag" signals of different pressure sensors exist at the same time, the brake will not respond to any calibration instructions and will automatically exit calibration.

[0128] If the three types of instructions, namely, setting instructions, self-test instructions and calibration instructions, do not exist independently, the brake motor will not respond to any of the aforementioned instructions and will automatically exit calibration and self-test.

[0129] When the brake motor is in the self-test process, if there is a calibration interface in multiple brake screens, that is, there is a "calibration interface flag" signal, the drive brake motor automatically exits the self-test.

[0130] If there is a setup command or calibration command, the brake motor will not respond to any of the aforementioned commands and will automatically exit self-test.
