[0015] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0016] Figure 1 This is a schematic diagram of a flood-proof and airtight door control system for a subway station according to one embodiment of this application; Figure 2 This is a schematic diagram of a control mode selection switch provided in an embodiment of this application. Detailed Implementation
[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0018] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] In one exemplary embodiment, such as Figure 1 As shown, a flood-proof and airtight door control system for subway stations is provided, including: a water level detection module, a main control module, a door drive mechanism, and a human-machine interaction module. The water level detection module, the door drive mechanism, and the human-machine interaction module are all connected to the main control unit.
[0020] The water level detection module is used to detect the water level at the entrance of subway stations in real time.
[0021] The main control module determines whether the water level detected by the water level detection module exceeds a first preset water level value. If the water level detected by the water level detection module exceeds the first preset water level value, the main control module generates a first alarm signal and determines the rate of water level rise based on the water level detected by the water level detection module. The main control module also determines whether the water level detected by the water level detection module exceeds a second preset water level value. If the rate of water level rise exceeds a set rate of rise or the water level detected by the water level detection module exceeds the second preset water level value, a second alarm signal is generated.
[0022] The human-machine interface module is used to display the first and second alarm signals. It is also used to acquire user commands.
[0023] The main control module is also used to generate door opening and closing control commands based on user instructions. The door drive mechanism controls the opening and closing of the flood-proof and airtight door according to the door opening and closing control commands.
[0024] The first alarm signal alerts operators of the subway station's flood-proof and airtight doors that the water level outside the station is abnormal, indicating that it has reached a first preset level. Operators should pay attention to the rate of water level rise. The second alarm signal alerts operators that the water level outside the station is rising too quickly (exceeding the preset rise rate) or that it has reached a second preset level. Operators should then input a user command to close the door into the human-machine interface module, enabling the flood-proof and airtight door control system to close the door.
[0025] Furthermore, when the human-machine interface module no longer displays alarm signals, i.e., when the water level drops below the first preset level, the operator can still input a user command to open the door, enabling the subway station flood-proof protective airtight door control system to control the opening of the flood-proof protective airtight door. The human-machine interface module can be a touchscreen display that shows relevant alarm signals and allows the operator to input corresponding user commands or auxiliary maintenance commands.
[0026] As an optional implementation, to ensure the normal operation of the subway station flood-proof and airtight door control system during power outages caused by sudden flooding or other abnormal situations, the subway station flood-proof and airtight door control system provided in this application can also be equipped with an emergency power supply module. For example... Figure 1 As shown, the emergency power module is connected to the main control module. The emergency power module provides emergency power to ensure that the subway station's flood-proof protective airtight door control system can continue to control the opening and closing of the flood-proof protective airtight doors after a power outage caused by a failure in the mains power circuit.
[0027] As an optional implementation, to enable remote communication between the main control module and the human-machine interface module, the subway station flood-proof and airtight door control system also includes a communication module. For example... Figure 1 As shown, the main control module and the human-machine interaction module are connected via a communication module. Communication between the main control module and the human-machine interaction module can be achieved via Wi-Fi, Bluetooth, or other methods.
[0028] As an optional implementation, to improve the reliability of the subway station flood-proof airtight door control system and prevent the water level detection module from being falsely triggered by splashing water from equipment, the water level detection module includes three identical water level gauges. In the main control module, if two or more of the three water level gauges detect the same water level, that water level is taken as the water level detected by the water level detection module. That is, the main control module receives the water levels detected by the three water level gauges respectively, and when two or three of them detect the same water level, it uses that water level as the water level detected by the water level detection module to determine whether it exceeds a first set water level value (or other set water level value), thereby preventing false alarms due to a single water level gauge malfunction. For example, three water level gauges of the same brand and model can be used. The three water level gauges are installed side by side, close to each other, at the same height in the same water collection well at the entrance of the subway station. During installation, it is only necessary to align the markings on the outer casing of the three water level gauges and adjust them to the set water level elevation.
[0029] As an optional implementation, to ensure emergency operation in case of module failure during control, the main control module is a redundant controller. This provides a backup channel for the subway station flood-proof airtight door control system, ensuring continuous system operation even if one of the redundant controllers fails. The redundant controller includes a main controller and a backup controller, which synchronize data and programs in real time. In the event of a main controller failure, the backup controller can take over control tasks within milliseconds, preventing interruptions. Furthermore, a human-machine interface module can display fault information for both the main and backup controllers. For example, the main control module can be a Siemens S7 redundant controller with a built-in self-diagnostic module. The backup FPGA (Xilinx Artix-7) is pre-installed with simplified control logic to generate relevant control commands.
[0030] As an optional implementation, to prevent operators from ignoring the first alarm signal due to unforeseen circumstances or other reasons, the main control module is also used to determine whether the water level detected by the water level detection module exceeds a first intermediate set water level value or a second intermediate set water level value. If the water level detected by the water level detection module exceeds the first intermediate set water level value, the main control module generates a third alarm signal. If the water level detected by the water level detection module exceeds the second intermediate set water level value, the main control module generates a fourth alarm signal. The human-machine interaction module is also used to display the third and fourth alarm signals.
[0031] Specifically, the water level is set in the order of a first set water level value, a first intermediate set water level value, a second intermediate set water level value, and a second set water level value, in conjunction with the water level detection module. Assuming the water level continues to rise, the water level detected by the water level detection module will sequentially reach the first set water level value, the first intermediate set water level value, the second intermediate set water level value, and the second set water level value.
[0032] As an optional implementation, to facilitate real-time monitoring and emergency operation, the subway station flood-proof protective airtight door control system also includes an auxiliary control module. The auxiliary control module is connected to the main control module. The auxiliary control module is used to acquire auxiliary maintenance instructions, and the main control module generates door opening and closing control instructions based on these instructions. The door drive mechanism controls the opening and closing of the subway station's flood-proof protective airtight doors according to the door opening and closing control instructions.
[0033] During the operation of the flood-proof and airtight door control system in subway stations, the auxiliary control module is directly electrically connected to the main control module. Operators can observe the equipment status and perform operations in real time. In case of emergency (such as network interruption or connection failure between the main control module and the human-machine interface module), auxiliary maintenance commands can be input through the auxiliary control module to ensure that the flood-proof and airtight door can be closed or opened in case of emergency, thereby improving the emergency response capability of the flood-proof and airtight door control system in subway stations.
[0034] As an optional implementation, to ensure accurate identification of the opening and closing status of the flood-proof protective airtight door, the subway station flood-proof protective airtight door control system also includes a fully open position switch and a fully closed position switch connected to the main control module. When the flood-proof protective airtight door reaches the fully open position, the fully open position switch opens, and the main control module generates a first locking command. When the flood-proof protective airtight door reaches the fully closed position, the fully closed position switch opens, and the main control module generates a second locking command.
[0035] The door drive mechanism includes: an oil pump, a door drive cylinder, a safety device, and a locking device. The oil pump, door drive cylinder, safety device, and locking device are all connected to the main control module. The safety device is located on one side of the bottom of the flood-proof protective airtight door. The locking device is located on the other side of the flood-proof protective airtight door.
[0036] The oil pump provides hydraulic power to the door drive cylinder. A safety device locks the flood-proof protective airtight door according to a first locking command when the switch is in the fully open position. A locking device locks the flood-proof protective airtight door according to a second locking command when the switch is in the fully closed position. The door drive cylinder moves the flood-proof protective airtight door using the hydraulic power provided by the oil pump.
[0037] The process of the door drive mechanism controlling the closing of the flood-proof airtight door in the subway station according to the door closing control command includes: according to the door closing control command, the oil pump starts to rotate, providing hydraulic power to the door drive cylinder. The safety device releases the lock on the flood-proof airtight door according to the door closing control command. After the flood-proof airtight door is fully closed to the fully closed position, the locking device locks the flood-proof airtight door according to the second control command, and the oil pump stops rotating.
[0038] The process by which the door drive mechanism controls the opening of the flood-proof airtight door in the subway station according to the door opening control command includes: Upon receiving the door opening control command, the oil pump starts rotating, providing hydraulic power to the door drive cylinder. The locking device releases the lock on the flood-proof airtight door according to the door opening control command. After the flood-proof airtight door is fully opened to the fully open position, the safety device locks the flood-proof airtight door according to the first control command, and the oil pump stops rotating.
[0039] In addition, the door drive mechanism may also include a manual drive device, which can be used to move the flood-proof and airtight door in extreme situations (such as when the flood-proof and airtight door control system of a subway station cannot operate normally).
[0040] In one exemplary embodiment, based on the specific structure of the subway station flood-proof and airtight door control system provided in the above embodiment, the control principle and application process of the subway station flood-proof and airtight door are described.
[0041] The water level detection module monitors the rainwater level at the subway station entrance. The main control module determines whether the water level exceeds a first preset value. If it does, a first alarm signal is generated, and the module also determines the rate of water level rise based on the detected water level. The main control module further determines whether the water level exceeds a first intermediate preset value, a second intermediate preset value, and a second preset value. If these values are exceeded, a third, fourth, and second alarm signal are generated, respectively. Additionally, a second alarm signal is generated when the rate of water level rise exceeds a set rate. The first, third, and fourth alarm signals alert operators to abnormal water levels at the subway station entrance. The second alarm signal indicates that the rate of water level rise at the subway station entrance has exceeded a set value or the water level has reached a second preset value, requiring operators to close the flood protection airtight door.
[0042] If the water level at the entrance of the subway station does not exceed the first set water level value, and the flood protection airtight door of the subway station is in the fully closed state, the operator can input the user command to open the door on the human-machine interaction module. The main control module generates the door opening control command according to the user command, and the door drive mechanism controls the flood protection airtight door to open according to the door opening control command.
[0043] The main control module may include a control logic function block, a communication function block, a fault statistics function block, and an equipment status function block. The control logic function block determines the water level detected by the water level detection module based on the water levels detected by the three sets of water level gauges in the water level detection module. The communication function block enables communication with other modules. The fault statistics function block records the time, frequency, and occurrence of faults. The equipment status function block records the control mode and operating / stopped states of the equipment.
[0044] The flood-proof and airtight door control system for subway stations can be installed in a control cabinet. The main control module can also be connected to a control mode selection switch. This switch allows selection of the connection method between the main control module and the auxiliary control module or human-machine interface module, corresponding to manual, maintenance, or remote control. Figure 2 As shown, the control mode selection switch allows you to choose between maintenance, manual, or remote control. Different control modes are selected via this switch, and each mode is relatively independent, ensuring no interference when switching between them. Remote control refers to the connection between the main control module and the human-machine interface module (or via a communication module), while manual and maintenance control refer to the connection between the main control module and the auxiliary control module.
[0045] When the control mode selection switch is in the maintenance position, the raising and lowering of the flood-proof protective airtight door can be controlled through the auxiliary control module for maintenance.
[0046] When the control mode selection switch is set to the manual position, the flood-proof protective airtight door can be controlled via the auxiliary control module. This allows operators to manually intervene while observing the system's operational status in real time. In emergencies (such as network interruptions or remote system failures), the opening and closing of the flood-proof protective airtight door can be performed quickly, ensuring its emergency response capability. Furthermore, it ensures the reliability of core functions: the auxiliary control module operates independently of the remotely connected human-machine interface module, preventing overall system failure due to communication failures or network attacks. The safety devices and locking devices of the door drive mechanism still support manual unlocking even in the event of a power outage, ensuring the safety of the subway station flood-proof protective airtight door control system under extreme conditions.
[0047] The main control module is the core decision-making module of the control system, responsible for data fusion, control logic calculation and system status management of multiple water level gauges.
[0048] The main control module acquires analog signals such as pressure and oil level from the oil pump in the door drive mechanism. These signals are then converted from digital signals via the main control module's AI channel and calculated to obtain the actual pressure and oil level. If the pressure exceeds the set value or the oil level in the tank is too low, the system must be shut down for protection until the pressure and oil level return to normal before the door drive mechanism can be used normally.
[0049] The principle of linear transformation in the main control module is as follows: Analog signals (e.g., 4-20mA) and the digital signals converted by the main control module (e.g., 6400-32000) have a linear relationship. The conversion formula is derived based on the direct proportional relationship of the coordinate system. The formula for converting digital signals to engineering quantities is expressed as: In the formula, This indicates the input digital value (i.e., the value of the data received by the main control module after A / D conversion). and For the upper and lower limits of the number (e.g., 32000 and 6400); and The upper and lower limits of the project quantity (e.g., 0MPa~20MPa), project quantity That is, the actual measured water level value of the water level gauge.
[0050] When flooding occurs at subway station entrances / exits, the main control module generates a corresponding alarm signal based on the water level detected by the water level detection module. This alarm signal is then displayed by the human-machine interface module (located in the subway station control room). Simultaneously, after generating the first alarm signal, the main control module calculates the rate of water level rise. If the rate of rise reaches a set value or the water level detected by the water level detection module reaches a second set value, a second alarm signal is immediately generated and sent to the human-machine interface module (i.e., a second alarm signal is sent to the subway station control room). Operators determine whether to close the door based on the alarm signal displayed on the human-machine interface module and issue a user command to close the door. The main control module then closes the flood-proof protective airtight door according to this command. The door drive mechanism closes the flood-proof protective airtight door according to the following procedure: (1) Start the oil pump and the oil pump starts to rotate.
[0051] (2) The door drive mechanism starts to build up pressure as the oil pump rotates, and the oil pump provides hydraulic power to the door drive cylinder.
[0052] (3) The safety device releases the lock on the flood protection airtight door. The safety device stops when it reaches the safety device exit position, that is, the safety device has released the lock on the flood protection airtight door.
[0053] (4) Stop closing the flood-proof and airtight door after it reaches the fully closed position.
[0054] (5) The locking device locks the flood protection airtight door. The locking device stops after reaching the locking device engaged position, that is, the locking device has completed locking the flood protection airtight door.
[0055] (6) The door drive mechanism stops building pressure and the oil pump stops rotating.
[0056] At this point, the locking device installed on the door is locked in place, and the indicator light connected to the locking device illuminates, indicating that the flood-proof and airtight door is completely closed.
[0057] Once the water level at the subway station entrance has receded and the operator has confirmed it is safe, they issue a user command to open the door via the human-machine interface module. This command then prompts the main control module to open the flood-proof and airtight door. The door drive mechanism will open the flood-proof and airtight door according to the following procedure: (1) Start the oil pump and the oil pump starts to rotate.
[0058] (2) The door drive mechanism starts to build up pressure as the oil pump rotates, and the oil pump provides hydraulic power to the door drive cylinder.
[0059] (3) The locking device releases the lock on the flood protection airtight door. The locking device stops when it reaches the lock device exit position, that is, the locking device has released the lock on the flood protection airtight door.
[0060] (4) Stop closing the flood-proof and airtight door after it has reached the fully open position.
[0061] (5) The safety device locks the flood protection airtight door. The safety device stops after it reaches the safety device engagement position, that is, the safety device has completed locking the flood protection airtight door.
[0062] (6) The door drive mechanism stops building pressure and the oil pump stops rotating.
[0063] At this point, the safety device installed on the door is locked in place, and the indicator light connected to the safety device illuminates, indicating that the flood-proof and airtight door has been fully opened.
[0064] Both the safety device and the locking device are used to lock the flood-proof protective airtight door. The safety device is located at the bottom of the outer side of the door, while the locking device is located on the inner side of the door. The safety device engages and disengages a safety pin via a small hydraulic pipe. When the door is fully open, the safety pin engages, ensuring the door remains stably open. The locking device is driven by a hydraulic motor, which in turn drives a worm gear via a chain, engaging and disengaging the locking head. When the door is fully closed, the locking head engages, ensuring the door remains stably closed.
[0065] In conjunction with the above embodiments, the subway station flood-proof and airtight door control system provided in this application has the following advantages.
[0066] In remote control mode (i.e., when the main control module is connected to the human-machine interface module), it can be controlled independently or the area of the flood protection airtight door in the protected section can be controlled. This allows operators to comprehensively analyze data such as water level and system equipment operation, and uniformly adjust the opening and closing strategy of the flood protection airtight door. When a water level warning is issued (i.e., the human-machine interface module displays an alarm signal), the flood protection airtight door can be remotely driven to close in batches, improving response efficiency.
[0067] The control system operates normally in subway stations using remote control. Manual control is used when remote control malfunctions, and maintenance is required when necessary. The flood-resistant airtight door control system's manual and remote control design ensures the reliability and safety of emergency operations through manual control, while enabling centralized management and intelligent decision-making through remote control. Together, they form a multi-layered protection system, effectively addressing flood control needs in complex environments.
[0068] In the water level detection module, the water level gauge can collect relevant data in a three-choose-two mode. That is, the control system is designed to collect signals from three sets of water level gauges. The system intelligently analyzes the water level detected by the water level gauges and automatically determines that the water level detected by two sets of water level gauges is consistent, which effectively reduces the risk of misjudgment.
[0069] The door drive mechanism is equipped with locking and safety devices to ensure the reliability of the door in the fully open and fully closed positions. The safety and locking devices can employ step-by-step control, which is more precise than traditional conventional control.
[0070] The opening and closing actions of the flood-proof protective airtight door are logically controlled by the control commands sent from the main control module to the door drive mechanism. The timer and counter in the main control module work together to realize the opening and closing speed curve control of the flood-proof protective airtight door, avoid mechanical impact, and make the door smoothly enter the position.
[0071] The control system program is modular, easy to understand and debug, with each functional block being relatively independent, and the program is concise.
[0072] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of the relevant data must comply with relevant regulations.
[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
