Description

Technical Field

[0001] This invention relates to the field of rail transit signal control technology, specifically to a turnout emergency control and status monitoring device based on a fully electronic execution unit, used to realize safe on-site emergency operation and status monitoring of turnouts when the interlocking host computer communication fails or is not available. Background Technology

[0002] In current turnout control circuits, the operation of existing fully electronic turnout actuators relies entirely on communication with a host computer. The host computer needs to issue commands and perform scheduling and switching operations. When communication with the host computer fails, or when the station lacks remote communication capabilities, the control and maintenance of the turnout are severely limited.

[0003] In existing technologies, current emergency control devices mainly target switch machine failures, and most are designed for the 6502 relay control system, with fewer devices designed for fully electronic systems. Current fully electronic turnout emergency control systems have emergency operation schemes, but these schemes involve processes such as camera verification, control room operator verification, and safety officer verification, resulting in high costs, complex procedures, and limited safety protection measures for the local control panel, thus requiring an improvement in safety levels.

[0004] The disadvantages of existing technologies include:

[0005] When the fully electronic actuator is used for turnout control on site, if there are situations such as communication interruption, poor station conditions, or the interlocking host computer not yet being installed, the turnout may not be able to operate or the turnout status may not be found, which will seriously affect train operation efficiency. An emergency operating system needs to be used for on-site operation.

[0006] The existing on-site control panel has limited protection measures, relies on human experience, and is at risk of misoperation; it also lacks status awareness and early warning capabilities, and the safety closed loop is incomplete.

[0007] The existing scheme has high risks in on-site operation. Station staff and safety officers need to work on-site with dispatchers on the line side for a long time, facing many hazards on the line side, which poses a high risk to personal safety. Summary of the Invention

[0008] In view of the above problems, the present invention is proposed to provide a turnout emergency control and status monitoring device based on a fully electronic actuator to overcome or at least partially solve the above problems. It can realize safe on-site emergency operation and control of the switch machine in the event of communication failure with the interlocking host computer or the absence of the interlocking host computer, and display the switch machine's operating status, current, power and other information in real time.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] This invention provides a turnout emergency control and status monitoring device based on a fully electronic actuator, comprising:

[0011] The local control panel is used by staff to issue control commands and display the current operating status and indication of the switch machine;

[0012] The emergency control structure for the switch machine is connected to the local control panel and is used to operate the switch machine according to the commands issued by the interlocking host computer or the local control panel, and to collect and store the indicators during the operation of the switch machine and the position status after the operation is completed.

[0013] The switch machine status monitoring industrial control computer is connected to the switch machine emergency control section and is used to record and display switch machine action data, including action direction, current curve and power curve.

[0014] In one embodiment, the switch machine emergency control structure includes an interlocking validity check module, used to detect the communication status of the interlocking host computer to determine whether to enable the local emergency control function; wherein, the interlocking validity check module makes the judgment by receiving valid communication packets from the interlocking host computer, the valid communication packets containing station data, version number and check bit information.

[0015] In one embodiment, the local operation panel includes:

[0016] A rotary power switch allows you to turn the control panel power on or off using a key.

[0017] The self-resetting push-button switch includes a main positioning button, a main reverse button, and a turnout number button, used to issue switch machine control commands;

[0018] Non-self-resetting buttons, including the center rail button and the switch rail button, are used to control the center rail and switch rail switch machines separately or simultaneously.

[0019] Status indicator lights are used to display the turnout's positioning, reverse position, turnout alarm, and operating status.

[0020] In one embodiment, the local operation panel further includes a built-in microprocessor; the microprocessor is connected to a power rotary switch, a self-resetting push-button switch, a non-self-resetting button, and a status indicator light, respectively.

[0021] The microprocessor includes:

[0022] The synchronization check module is used to perform basic synchronization checks on the operation buttons; the synchronization check module is configured as follows:

[0023] Detect the press events of the turnout number button and the main positioning button or the main reverse button;

[0024] A timer is started immediately after a button press is detected to calculate the time interval between two button presses.

[0025] If the time interval is less than the first preset duration, the basic synchronization check will be passed, and the next operation stage can be allowed.

[0026] If the time interval is greater than or equal to the first preset duration, the operation is deemed invalid. The system is reset and waits for the first preset duration before allowing the operation to be repeated, generating the first abnormal signal and recording the abnormal event.

[0027] In one embodiment, the microprocessor further includes:

[0028] The intelligent time series analysis module is used to perform millisecond-level interval analysis on operations that pass the basic synchronization check; the intelligent time series analysis module is configured as follows:

[0029] The actual time interval between button presses is measured and divided into two levels: when the millisecond interval is less than the second preset duration, it is determined to be ideal synchronization;

[0030] When the millisecond interval is greater than or equal to the second preset duration and less than the first preset duration, it is determined to be an acceptable synchronization.

[0031] The time-series data of ideal synchronization and acceptable synchronization are compared with the historical behavior model to update the operator's behavior habit data.

[0032] Based on the comparison results, the baseline for the normal operating mode is optimized.

[0033] In one embodiment, the microprocessor further includes:

[0034] An operation behavior pattern determination module is used to determine whether the operation pattern is abnormal based on the results of intelligent time series analysis; the operation behavior pattern determination module is configured as follows:

[0035] The temporal characteristics of the current operation are compared with the historical behavior model. The temporal characteristics include the interval time of button press and the tendency of the press sequence.

[0036] If the current operating characteristics match historical habits, the mode is determined to be normal, and the control command is executed directly;

[0037] If the current operating characteristics deviate significantly from historical habits, it is determined to be an abnormal pattern, triggering a security alert and initiating a secondary verification process.

[0038] In one embodiment, the microprocessor further includes:

[0039] The secondary verification module is used to perform additional verification when the pattern is abnormal; the secondary verification module is configured as follows:

[0040] When a safety alarm is triggered, the turnout number indicator light on the control panel flashes red.

[0041] Within the third preset time window, it checks whether the same main positioning or main reversal button is pressed again;

[0042] If the button is detected to be pressed again within the third preset time window, the secondary verification is deemed successful, and an execution command is output.

[0043] If the button is not pressed again within the third preset time window, the secondary verification is deemed to have failed, a second abnormal signal is generated, and the system lock mechanism is triggered.

[0044] In one embodiment, the microprocessor further includes:

[0045] The system locking module is used to disable the operation panel function after multiple abnormal operations; the system locking module is configured as follows:

[0046] Maintain an exception counter to record invalid operation events, which is used to record the number of occurrences of the first exception signal and the second exception signal;

[0047] If the error counter accumulates to the preset number of times within the fourth preset time window, the system will be locked, temporarily disabling all functions of the control panel except for the power switch, for the fifth preset time.

[0048] During the lockout period, record safety event logs to the switch machine status monitoring industrial control computer;

[0049] After the lock is released, the error counter will be automatically cleared and normal operation will resume.

[0050] In one embodiment, the switch machine emergency control structure includes:

[0051] A switch machine operation module is used to control the switching of the switch machine; the switch machine operation module introduces the turnout operation power supply and the indication power supply through the interface, and outputs the switch machine control line signal;

[0052] The maintenance and acquisition module is used to collect the switch machine's operating status, position information, current curve, and power curve, and send the data to the switch machine status monitoring industrial control computer.

[0053] In one embodiment, the device prioritizes receiving commands from the interlocking host computer when communication with the host computer is normal, and enables the local operation panel control function when communication fails or the interlocking host computer is unavailable.

[0054] As can be seen from the above technical solution, compared with the prior art, the present invention has the following technical advantages:

[0055] 1. This invention has strong versatility and can operate under both conditions where an interlocking host computer is available and where an interlocking host computer is not available.

[0056] 2. In the absence of an interlocking host computer, the present invention can improve the safety of the system. The local operation panel has a logic protection function, and the control module will not operate the switch machine if the button pressing sequence is not correct.

[0057] 3. This invention has monitoring and maintenance functions, which can send maintenance information to an industrial control computer outside the execution cabinet, making it convenient for on-site experimental personnel to view and analyze the data.

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] This invention discloses a turnout emergency control and status monitoring device based on a fully electronic actuator, comprising:

[0070] The local control panel is used by staff to issue control commands and display the current operating status and indication of the switch machine;

[0071] The emergency control structure for the switch machine is connected to the local control panel and is used to operate the switch machine according to the commands issued by the interlocking host computer or the local control panel, and to collect and store the indicators during the operation of the switch machine and the position status after the operation is completed.

[0072] The switch machine status monitoring industrial control computer is connected to the switch machine emergency control section and is used to record and display switch machine action data, including action direction, current curve and power curve.

[0073] like Figure 1 As shown, the device is placed outdoors and consists of three parts: a local operation panel, a switch machine emergency control structure, and a switch machine status monitoring industrial control computer. The local operation panel is a human-machine interface, used by staff to issue commands and display the current actions and status of the switch machine. The switch machine emergency control structure connects to the local operation panel, the interlocking host computer, and the switch machine itself. It can operate the switch machine according to commands issued by the interlocking host computer or the local operation panel, supply power to the switch machine, and collect and store indicators during the switch machine's operation and its position status after the operation is completed. The switch machine status monitoring industrial control computer receives monitoring information sent by the switch machine emergency control structure and can record and display data indicators for each switch machine operation, including the direction of action, current curve, and power curve, facilitating staff to view historical records and providing data support for fault diagnosis and experimental progress.

[0074] like Figure 1 As shown, the emergency control structure of the switch machine includes:

[0075] 1) The interlocking validity check module is used to detect the communication status of the interlocking host computer to determine whether to enable the local emergency control function. The interlocking validity check module judges by receiving valid communication packets from the interlocking host computer. For example, if the station data, version number, check bit and other information in the received valid communication packet are correct, it is considered a valid communication packet. In this case, the interlocking host computer is considered to be in a valid control state, and the local control function will not be activated.

[0076] 2) Switch machine operation module, used to control switch machine switching; the switch machine operation module introduces turnout operation power and indication power through interface, and outputs switch machine control line signal;

[0077] 3) The maintenance and acquisition module is used to collect the switch machine's operating status, position information, current curve and power curve, and send the data to the switch machine status monitoring industrial control computer.

[0078] When the communication with the interlocking host computer is normal, the device prioritizes receiving commands from the interlocking host computer. When communication fails or the interlocking host computer is unavailable, the device enables the local operation panel control function.

[0079] In the emergency control structure of the switch machine, the first step is to check the validity of the interlocking host computer under the current environmental conditions; the check process is shown in Figure 2. First, the interlocking validity check module determines whether the current interlocking host computer has the necessary control conditions and decides whether to activate the emergency local control function. When communication conditions are not met, after confirming that emergency control can be activated, staff can operate the local control panel. If the operation command is deemed valid, the switch can be driven to switch based on the switch machine operation module, thus controlling and switching the switch. Simultaneously, the maintenance and acquisition module also collects information from the control panel buttons. Finally, after the switch switching action is completed, the maintenance and acquisition module in the switch machine emergency control structure sends the operation information and switch machine status indicators as monitoring information to the switch machine status monitoring industrial control computer, allowing staff to view the switch status data under the current operation in real time.

[0080] Once the local control panel is enabled, operators can control the turnouts through it. The control panel interface is shown in Figure 3, and includes:

[0081] A rotary power switch allows you to turn the control panel power on or off using a key.

[0082] The self-resetting push-button switch includes a main positioning button, a main reverse button, and a turnout number button, used to issue switch machine control commands;

[0083] Non-self-resetting buttons, including the center rail button and the switch rail button, are used to control the center rail and switch rail switch machines separately or simultaneously.

[0084] Status indicator lights are used to display the turnout's positioning, reverse position, turnout alarm, and operating status.

[0085] The local control panel also includes a built-in microprocessor; it is connected to the power rotary switch, self-resetting push-button switch, non-self-resetting push-button, and status indicator lights. This microprocessor implements logic protection functions through software and communicates with the switch machine's emergency control structure, including functional modules such as... Figure 4 As shown: Synchronous inspection module 41, intelligent timing analysis module 42, operation behavior pattern judgment module 43, secondary verification module 44, and system locking module 45.

[0086] The synchronization check module 41 performs a basic synchronization check on the operation buttons; the synchronization check module 41 is configured as follows:

[0087] a. Detect the press events of the turnout number button and the main positioning button or the main reverse button;

[0088] b. Start the timer immediately after a button press is detected to calculate the time interval between two button presses;

[0089] c. If the time interval is less than the first preset duration, then the basic synchronization check is passed, and the next operation stage is allowed;

[0090] d. If the time interval is greater than or equal to the first preset duration, the operation is deemed invalid, the system is reset and waits for the first preset duration before allowing the operation to be repeated, a first abnormal signal is generated, and the abnormal event is recorded.

[0091] The intelligent timing analysis module 42 performs millisecond-level interval analysis on operations that pass the basic synchronization check; the intelligent timing analysis module 42 is configured as follows:

[0092] a. Measure the actual time interval between button presses and divide it into two levels: when the millisecond interval is less than the second preset duration, it is determined to be ideal synchronization;

[0093] b. When the millisecond interval is greater than or equal to the second preset duration and less than the first preset duration, it is determined to be an acceptable synchronization;

[0094] c. Compare the ideal synchronization and acceptable synchronization time series data with the historical behavior model respectively, and update the operator's behavior habit data;

[0095] d. Based on the comparison results, optimize the benchmark for normal operation mode.

[0096] The operation behavior pattern judgment module 43 determines whether the operation pattern is abnormal based on the intelligent timing analysis results; this operation behavior pattern judgment module 43 is configured as follows:

[0097] a. Compare the temporal characteristics of the current operation with the historical behavior model. The temporal characteristics include the interval time of button presses and the tendency of the pressing sequence.

[0098] b. If the current operating characteristics match historical habits, the mode is determined to be normal, and the control command is executed directly;

[0099] c. If the current operating characteristics deviate significantly from historical habits, it is determined to be an abnormal pattern, triggering a security alarm and initiating a secondary verification process.

[0100] Secondary verification module 44, used to perform additional verification in case of pattern anomalies; is configured as follows:

[0101] a. When a safety alarm is triggered, the turnout number indicator light on the control panel will flash red;

[0102] b. And within the third preset time window, check whether the same main positioning or main reversal button is pressed again;

[0103] c. If the button is detected to be pressed again within the third preset time window, the secondary verification is determined to be successful, and an execution command is output;

[0104] d. If the button is not pressed again within the third preset time window, the secondary verification is deemed to have failed, a second abnormal signal is generated, and the system lock mechanism is triggered.

[0105] System lock module 45, used to disable the operation panel function after multiple abnormal operations; configured as follows:

[0106] a. Maintain an exception counter to record invalid operation events, which is used to record the number of occurrences of the first exception signal and the second exception signal;

[0107] b. If the error counter accumulates to the preset number of times within the fourth preset time window, the system will be locked, temporarily disabling all functions of the control panel except for the power switch, for the fifth preset time.

[0108] c. During the lockout period, record safety event logs to the switch machine status monitoring industrial control computer;

[0109] d. The error counter will be automatically cleared after the lock is released, and normal operation will resume.

[0110] The operation judgment logic of the local operation panel is as follows: Figure 5 As shown: including the following steps (1) to (4);

[0111] (1) Turn on the power with the key and enable the control panel.

[0112] The power rotary switch is the power switch for the control panel. It is turned on with the key before each operation and turned off with the key after each operation.

[0113] (2) The overall positioning, overall reversal, and turnout number buttons are self-resetting push-button switches. When performing a normal operation on the switch machine, press the turnout number button and the overall positioning button simultaneously; when performing a reverse operation on the switch machine, press the turnout number button and the overall reversal button simultaneously. The program will perform synchronization checks and intelligent timing analysis. For example... Figure 6 As shown, the specific process is as follows:

[0114] A. Basic Synchronization Check

[0115] Once the microprocessor's synchronization check module 41 detects that the "switch number" and "general positioning / general reversal" buttons have been pressed, it immediately starts timing.

[0116] Pass: If the time interval between pressing the two buttons is less than 3 seconds, then pass the first level check and proceed to the next level.

[0117] Failure: If the interval is greater than or equal to 3 seconds, it is judged as "basic timeout" and the operation is invalid. The system will reset, and the operator must wait 3 seconds before the next operation can be performed. At the same time, this event will be recorded in the "anomaly counter".

[0118] B. Intelligent Time Series Analysis

[0119] In valid operations that pass the first-level check, the intelligent timing analysis module 42 will accurately measure the actual millisecond interval between the two buttons.

[0120] Time series are classified into categories:

[0121] Ideal synchronization (interval < 100ms): This is considered a highly skilled operation, possibly performed by an experienced operator. The system will record this time interval in the operator's (or this control panel's) behavioral model to optimize future "normal mode" benchmarks.

[0122] Acceptable synchronization (100ms - 3s interval): This is considered a valid standard operation and is also used to update the behavior model.

[0123] C. Judgment of operational behavior patterns

[0124] The operation behavior pattern judgment module 43 compares the temporal characteristics of the current operation (interval time, subtle tendencies in the pressing sequence, etc.) with the historically established behavior models. It divides the analysis into two modes:

[0125] Normal mode: If the characteristics of this operation are consistent with historical habits (for example, an operator is accustomed to pressing the turnout number first, and then pressing the general positioning after 150ms), the command will be executed directly.

[0126] Abnormal pattern: If the characteristics of this operation deviate significantly from historical habits, for example, if the operator suddenly operates at an extremely fast speed of 10ms, or the order is reversed, a security alarm will be triggered, and the secondary verification process will be initiated.

[0127] D. Secondary verification and system lockout

[0128] The secondary verification process of the secondary verification module 44:

[0129] When the system is determined to be "abnormal mode", the "turnout number" indicator light on the control panel will flash red.

[0130] For example, the operator needs to press the same "General Position" or "General Reverse Position" button again within 5 seconds.

[0131] Successful confirmation: The system will then execute the command.

[0132] If the confirmation fails, the operation is deemed invalid and the system is locked.

[0133] System locking mechanism:

[0134] In the system locking module 45, any event that causes "operation invalid", including basic timeout and secondary verification failure, will increment the "exception counter" by 1.

[0135] If the "abnormal counter" accumulates to 3 times within a short period of time (within 30 minutes), the system will determine that there may be a security risk and trigger a system lock.

[0136] During the lockout: All functions of the control panel, except for the power switch, are temporarily disabled for 5 minutes. Simultaneously, the system will record a "safety event log" in the monitoring industrial computer.

[0137] Lockout: The system will automatically unlock after 5 minutes, the "abnormal counter" will be cleared, and normal operation will resume.

[0138] (3) The center rail and switch rail buttons below the control panel are non-self-resetting and are used to control the center rail and switch rail separately or simultaneously. After operation, they need to be pressed to reset.

[0139] (4) For multi-machine traction turnouts, when multiple switch machines are in the correct position simultaneously, the turnout positioning green light will remain constantly on. When multiple switch machines are in the reverse position simultaneously, the turnout reverse yellow light will remain constantly on. If any one of the multiple switch machines fails to complete its operation, the turnout derailment alarm red light will remain constantly on. During the operation of the switch machine, the operation indicator green light will flash.

[0140] When the emergency control structure for the switch machine detects an operation on the local control panel, if the operation is a valid command, it sends the command to the switch machine operation module. Each switch machine operation module can control one switch machine. After receiving the switch machine control command from the local control panel, it controls the switch machine to switch positions. Figure 7 As shown, taking an AC turnout as an example, the switch machine operation module introduces the turnout operation power supply through the turnout operation power supply interface (A380, B380, C380); introduces the turnout indication power supply through the turnout indication power supply interface (BJZ220, BJF220); and leads out the switch machine control lines (X1, X2, X3, X4, X5) through the turnout control interface.

[0141] Among them, the operation is a valid command, which means: that is, the process of steps (1) to (3) above: the power rotary switch is the power switch of the control panel. It is turned on with the key before each operation and turned off with the key after the operation. The total positioning, total reversal, and turnout number are self-resetting push button switches. When performing a fixed operation on the switch machine, press the turnout number button and the total positioning button at the same time (with an interval of less than 3 seconds). If the buttons are out of sync, they need to be reset. After resetting, the next operation can be performed after an interval of 3 seconds. When performing a reverse operation on the switch machine, press the turnout number button and the total reversal button at the same time (with an interval of less than 3 seconds). If the buttons are out of sync, they need to be reset. After resetting, the next operation can be performed after an interval of 3 seconds. The total positioning and total reversal are invalid when operated at the same time.

[0142] During operation, the switch machine operation module collects the switch machine's operational status and position information, i.e., from positioning to reverse position, and from reverse position to fault position; a dedicated maintenance acquisition module collects information such as switch machine current, and collects and stores turnout current curves and power curves; when the switch machine status monitoring industrial control computer calls for turnout curves, it uploads the turnout current curve and power curve, such as... Figure 8 As shown.

[0143] This invention provides a turnout emergency control and status monitoring device based on a fully electronic execution unit. By detecting the communication status with the interlocking host computer, it can operate simultaneously under both conditions where the interlocking host computer is present and where it is not. 1) When the communication status is normal, it indicates that the interlocking host computer is working normally, and this device does not process the data collected by the local control panel, but only accepts commands from the interlocking host computer. 2) When the interlocking host computer is not present or communication with it is interrupted, the buttons on the local control panel are enabled.

[0144] In addition, the local control panel has a logic protection function, performs synchronous checks and intelligent timing analysis, and has local control panel status perception capabilities and alarm methods to prevent misoperation; furthermore, the device has local monitoring and maintenance functions, eliminating the need for staff to return to the signal room, and allowing them to view logs while performing local operations by the trackside.

If the time interval is greater than or equal to the first preset duration, the operation is deemed invalid, the system is reset and waits for the first preset duration before allowing the operation to be repeated, a first abnormal signal is generated, and the abnormal event is recorded. The intelligent time series analysis module is used to perform millisecond-level interval analysis on operations that pass the basic synchronization check; the intelligent time series analysis module is configured as follows: The actual time interval between button presses is measured and divided into two levels: when the millisecond interval is less than the second preset duration, it is determined to be ideal synchronization; When the millisecond interval is greater than or equal to the second preset duration and less than the first preset duration, it is determined to be an acceptable synchronization. The time-series data of ideal synchronization and acceptable synchronization are compared with the historical behavior model to update the operator's behavior habit data. Based on the comparison results, optimize the benchmark for normal operation mode; The operation behavior pattern judgment module is used to determine whether the operation pattern is abnormal based on the intelligent time series analysis results; the operation behavior pattern judgment module is configured as follows: The temporal characteristics of the current operation are compared with the historical behavior model. The temporal characteristics include the interval time of button press and the tendency of the press sequence. If the current operating characteristics match historical habits, the mode is determined to be normal, and the control command is executed directly; If the current operating characteristics deviate significantly from historical habits, it is determined to be an abnormal pattern, triggering a security alert and initiating a secondary verification process; The secondary verification module is used to perform additional verification when the pattern is abnormal; the secondary verification module is configured as follows: When a safety alarm is triggered, the turnout number indicator light on the control panel turns red and flashes. Within the third preset time window, it checks whether the same main positioning or main reversal button is pressed again; If the button is detected to be pressed again within the third preset time window, the secondary verification is deemed successful, and an execution command is output. If the button is not pressed again within the third preset time window, the secondary verification is deemed to have failed, a second abnormal signal is generated, and the system lock mechanism is triggered. The system locking module is used to disable the operation panel function after multiple abnormal operations; the system locking module is configured as follows: Maintain an exception counter to record invalid operation events, which is used to record the number of occurrences of the first exception signal and the second exception signal; If the error counter accumulates to the preset number of times within the fourth preset time window, the system will be locked, temporarily disabling all functions of the control panel except for the power switch, for the fifth preset time. During the lockout period, record safety event logs to the switch machine status monitoring industrial control computer; After the lock is released, the error counter will be automatically cleared and normal operation will resume.
