[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] Please refer to Figure 1 and Figure 2 , an embodiment of the present invention provides an automatic gate, the automatic gate comprising: a main case 1, a sub-case 2, and a gate body 3 arranged between the main case 1 and the sub-case 2;

[0031] One end of the gate body 3 is movably connected to the main chassis 1, and a movement space for the gate body 3 to move is provided between the main chassis 1 and the auxiliary chassis 2;

[0032] A locking assembly 21 is provided in the sub-chassis 2, and the movement trajectory of the gate body 3 is divided into a fast action section and a slow-speed sensing section. When the movement of the gate body 3 is in the slow-speed sensing section, the other end of the gate body 3 is inductively matched with the locking assembly 21 of the sub-chassis 2.

[0033] By setting up a double box structure consisting of the main box 1 and the auxiliary box 2, the gate body 3 moves between the two boxes. This design provides a more stable support and a more precise movement trajectory for the gate body 3.

[0034] Specifically, the gate body 3 maintains rapid movement during most of the movement process, but enters a slow-speed sensing section when approaching the auxiliary chassis 2. This design allows the gate to move at a lower speed during the most critical locking stage, thereby greatly improving the positioning accuracy.

[0035] In addition, the present application sets a locking assembly 21 in the auxiliary case 2, which cooperates with the deceleration sensing section of the gate body 3. When the gate body 3 enters the deceleration sensing section, it can accurately sense and match the locking assembly 21. This design ensures that the gate can be accurately locked and can automatically adjust to the correct position even if there is a slight deviation.

[0036] Furthermore, the main box 1 refers to a structure for accommodating and supporting one end of the gate body 3, which can be specifically implemented by a box made of metal material. The sub-box 2 refers to the other end structure opposite to the main box 1, which is used to accommodate the locking assembly 21, and can be specifically implemented by a metal box similar to the main box 1.

[0037] The locking assembly 21 refers to a mechanism for fixing the gate body 3, and can be implemented by an electromagnetic lock or a mechanical lock.

[0038] Specifically, the movement trajectory of the gate body 3 is divided into a fast action section and a slow speed sensing section. The fast action section refers to the initial stage of the movement of the gate body 3, which can be realized by high-speed motor drive. The slow speed sensing section refers to the final stage of the gate body 3 approaching the auxiliary chassis 2, which can be realized by a reduction motor or a buffer mechanism.

[0039] The core innovation of this application is the introduction of a double-box structure and a segmented motion trajectory design. Through the arrangement of the main box 1 and the auxiliary box 2, a stable support and an accurate motion trajectory are provided for the gate body 3. The motion trajectory is divided into a fast action segment and a slow-speed sensing segment, and combined with the locking assembly 21 in the auxiliary box 2, the gate body 3 is accurately positioned and locked. This design effectively solves the problem of movement deviation of the gate body 3 and improves the protective performance of the gate.

[0040] Here’s how this application works:

[0041] First, one end of the gate body 3 is fixed in the main box 1 by a movable connection, which can be a hinge or a slide rail structure, to ensure that the gate body 3 can stably perform opening and closing movements. An action space is set between the main box 1 and the auxiliary box 2. The size and shape of this space match the movement trajectory of the gate body 3, which not only provides a sufficient range of movement, but also limits possible deviations.

[0042] The movement of the gate body 3 is divided into two stages: the fast action stage and the slow speed sensing stage. In the fast action stage, the gate body 3 is driven by a high-speed motor to quickly complete most of the switching actions. When the gate body 3 approaches the auxiliary chassis 2, it enters the slow speed sensing stage. At this time, the drive system switches to the low speed mode or starts the buffer mechanism to make the gate body 3 move at a lower speed.

[0043] The locking assembly 21 provided in the auxiliary case 2 plays a key role in the deceleration sensing section. When the gate body 3 enters the deceleration sensing section, the locking assembly 21 starts to perform induction matching with the gate body 3. This can be achieved by a magnetic sensor or a photoelectric sensor. The induction system can accurately detect the position of the gate body 3 and guide it to accurately align with the locking position.

[0044] Once the gate body 3 reaches the predetermined position, the locking assembly 21 is immediately activated, which can be an electromagnetic lock adsorption or a mechanical lock snap-on, to firmly fix the gate body 3 on the auxiliary chassis 2. This design ensures that the gate body 3 can be accurately locked even in the presence of a slight offset, thereby improving the reliability and safety of the entire system.

[0045] Specifically, the automatic gate is a lifting gate structure, or the automatic gate is a section sliding gate structure.

[0046] The lifting gate drives the gate body 3 to swing around the main box 1 through the driving component of the main box 1, so that the gate body 3 can open and close the gate in a movement similar to that of a gate knife.

[0047] The segmented sliding gate structure can slide in sections in the horizontal direction, and can be opened flexibly in limited space. The specific implementation method can be to divide the gate body 3 into multiple horizontal sections, and each section is connected to the main box 1 and the auxiliary box 2 through a slide rail. When it needs to be opened, each section can slide into the main box 1 or the auxiliary box 2 in turn, so as to realize the opening of the gate. This structure is particularly suitable for places with limited horizontal space, such as narrow passages or corridors.

[0048] The existing automatic gate is mainly controlled by a preset control system. The gate sensor recognizes vehicle information and automatically opens and closes the gate, or the operator manually controls the gate opening and closing. Since the existing gate uses an aluminum alloy frame as the main structural material, the gate body 3 has a weak structural rigidity. During the telescopic movement or lifting movement of the gate body 3, it is easily affected by external environmental factors, resulting in the movement deviation of the gate body 3, affecting the accuracy of the gate body 3 closing state, thereby affecting the protective performance of the gate.

[0049] Specifically, the gate body 3 includes an upper cross bar 31 and a lower cross bar 32 arranged in parallel, and the upper cross bar 31 and the lower cross bar 32 are both aluminum alloy frame structures, and reinforcing steel wires are arranged inside the upper cross bar 31 and the lower cross bar 32. This structural design can significantly enhance the rigidity and strength of the gate body 3. Specifically, the upper cross bar 31 and the lower cross bar 32 can adopt a hollow structure, and a reinforcing steel wire is arranged inside. The reinforcing steel wire can be a high-strength steel wire rope or a steel cable, and its diameter can be selected according to the size and load-bearing requirements of the gate. For example, a steel wire rope with a diameter of 3mm to 10mm can be selected.

[0050] The reinforcing steel wire can be set to a taut state inside the upper and lower cross bars 32, so that the overall structural rigidity of the gate body 3 is improved. For example, a tension adjustment device, such as a bolt adjustment mechanism, can be set at both ends of the cross bar to adjust the tension of the steel wire. This design not only enhances the overall strength of the gate, but also improves the protective performance of the gate. At the same time, the parallel arrangement of the upper and lower cross bars 32 can ensure that the gate remains stable during the opening and closing process, further improving the accuracy and reliability of the gate movement.

[0051] In addition, the reinforcement wires can be arranged in parallel or crosswise to further enhance the structural strength. For example, 2-4 parallel reinforcement wires can be arranged inside each crossbar, or multiple wires can be arranged in a cross-weaving manner. This multiple reinforcement method can more effectively disperse external forces and improve the impact resistance and service life of the gate.

[0052] By arranging the reinforcing steel wire inside the upper and lower cross bars 32, the structural rigidity of the gate body 3 of the present application is significantly improved. This design can effectively solve the problem of weak structural rigidity of the automatic gate body 3. The reinforcing steel wire can provide additional support force to reduce the deviation of the gate caused by external environmental factors during movement. As a result, the movement of the gate body 3 is more stable, the accuracy of the gate closing state is improved, and the overall protection performance of the gate is enhanced.

[0053] Specifically, the automatic gate further includes a locking module 4 , which is disposed on the ground; the locking module 4 is provided with an electromagnetic locking mechanism, which is used to magnetically lock the gate body 3 .

[0054] Specifically, the locking module 4 can be installed on the ground in various forms. For example, the locking module 4 can be embedded in the ground so that it is flush with the ground to avoid affecting the passage of pedestrians or vehicles. Another way is to fix the locking module 4 on the ground to form a structure slightly higher than the ground. This design can better protect the locking module 4 and is also convenient for maintenance and replacement.

[0055] The electromagnetic locking mechanism is the core component of the locking module 4, and its working principle is based on electromagnetic attraction. When the gate body 3 is in the closed position, the electromagnetic locking mechanism is energized to generate a strong magnetic field, which firmly adsorbs the gate body 3 in the predetermined position. This design not only provides a strong locking force, but also has the characteristics of rapid response. When the gate needs to be opened, just cut off the power supply of the electromagnetic locking mechanism, the magnetic field disappears, and the gate body 3 can be easily released.

[0056] Furthermore, the electromagnetic locking mechanism can be designed as a multi-point locking form. For example, multiple locking points can be evenly distributed at the bottom of the gate body 3, and each locking point corresponds to an electromagnetic locking unit. This design can ensure that the gate body 3 can obtain a uniform locking force throughout the entire length range, further improving the locking effect and stability.

[0057] The technical solution of the present application solves the problem of poor locking effect of the automatic gate by configuring a locking module 4 on the ground and setting an electromagnetic locking mechanism. The electromagnetic locking mechanism can magnetically lock the gate body 3, thereby enhancing the locking effect of the gate. This design not only improves the stability and safety of the gate, but also effectively prevents the movement deviation of the gate body 3 caused by external environmental factors, ensures the accuracy of the gate closing state, and thus improves the overall protection performance of the gate.

[0058] Specifically, the inner steel wire of the lower cross bar 32 is configured with a plurality of iron block nodes, and the electromagnetic locking mechanism of the locking module 4 is distributed in a one-to-one correspondence with the iron block nodes. By configuring a plurality of iron block nodes on the inner steel wire of the lower cross bar 32, the electromagnetic locking mechanism of the locking module 4 is distributed in a one-to-one correspondence with the iron block nodes. This design can achieve multi-point precise positioning and locking, and improve the accuracy and stability of gate locking. Specifically, the iron block nodes can be in a variety of shapes and sizes, such as spherical, cylindrical or square, and their diameter or side length can be adjusted according to the size of the lower cross bar 32, usually between 5mm and 20mm. The number and distribution of the iron block nodes can also be designed according to the length and locking requirements of the gate, for example, an iron block node is set every 20cm to 50cm.

[0059] The electromagnetic locking mechanism can be an electromagnet or a combination of a permanent magnet and an electromagnet. When the gate is closed, the electromagnetic locking mechanism is activated, generating a strong magnetic field, which produces magnetic adsorption with the corresponding iron block nodes. This one-to-one distribution ensures that the gate is locked at multiple points at the same time, greatly improving the stability of the locking. For example, for a 2-meter-long gate, 5 iron block nodes and corresponding 5 electromagnetic locking points can be set, and the adsorption force of each point can reach 50N to 100N.

[0060] In addition, the provision of the iron block node also enhances the structural strength of the lower crossbar 32. Since the iron block node is tightly combined with the internal steel wire, they together form a more solid skeleton structure, thereby improving the rigidity of the entire gate body 3. This not only helps prevent the gate from being deformed or offset during movement, but also improves the impact resistance and service life of the gate.

[0061] In actual application, when the gate body 3 moves to the slow-speed sensing section, the sensing module will accurately identify the position of the gate body 3. The locking module 4 adjusts the position of the electromagnetic locking mechanism based on this information to ensure accurate alignment with the iron block node. When the gate is fully closed, the electromagnetic locking mechanism is activated to form a stable magnetic connection with the iron block node. This multi-point locking method not only improves the protection performance of the gate, but also can effectively resist interference from external forces, such as wind or human push and pull.

[0062] Embodiment 2:

[0063] Please refer to Figure 3 The embodiment of the present invention provides a control system for an automatic gate, the control system is used to realize the locking control of the automatic gate, and the control system includes:

[0064] Main control module 10: used to drive the gate body 3 to expand or retract;

[0065] Sensing module 30: used to identify the movement position of the gate body 3;

[0066] Locking module 20: used to lock the movement state of the gate body 3.

[0067] Specifically, the main control module 10 can be driven by a motor or hydraulically to control the movement of the gate body 3. For example, a stepper motor or a servo motor can be used to achieve precise position control. The main control module 10 can also include a microprocessor for processing signals from the sensing module 30 and generating corresponding control instructions.

[0068] The sensing module 30 can use a variety of sensor technologies to identify the movement position of the gate body 3. Among them, photoelectric sensors, magnetic sensors or position encoders can be used. For example, a photoelectric switch can be installed at a key position of the gate body 3, and a signal is triggered when the gate body 3 passes, thereby accurately determining the position of the gate. Another way is to use a rotary encoder to directly measure the movement distance and speed of the gate body 3.

[0069] The locking module 20 can be in the form of an electromagnetic lock or a mechanical lock. When the sensing module 30 detects that the gate body 3 has reached the specified position, the locking module 20 will immediately start the locking mechanism. For example, an electromagnet can be used to achieve rapid locking, or a mechanical buckle can be used to achieve reliable locking. The locking module 20 can also include a feedback mechanism to ensure the successful execution of the locking operation.

[0070] The collaborative working process between these three modules is as follows: First, the main control module 10 drives the gate body 3 to move according to the gate opening and closing instructions. During the movement, the sensing module 30 continuously monitors the position of the gate body 3 and feeds back the position information to the main control module 10. When the gate body 3 approaches the target position, the main control module 10 may reduce the movement speed to ensure accurate positioning. Finally, when the sensing module 30 confirms that the gate body 3 has reached the specified position, the main control module 10 will issue a command to activate the locking module 20 to perform the locking operation.

[0071] Through this coordinated control, the automatic gate control system of the present application can effectively solve the problem of gate body 3 movement deviation in the prior art. The real-time position feedback of the sensing module 30 enables the system to adjust the movement of the gate body 3 in a timely manner, reducing the influence of external environmental factors. The precise control of the locking module 20 ensures that the gate is locked in the correct position, greatly improving the accuracy of the gate body 3 closing state.

[0072] In addition, the system can also integrate remote monitoring and diagnostic functions. Through network connection, managers can monitor the status of the gate in real time, including the number of opening and closing times, operating time, locking status, etc. The system can also automatically generate operation reports to help maintenance personnel identify potential problems in a timely manner and improve the long-term reliability of the gate.

[0073] In this regard, the present application further proposes that the main control module 10 generates a door opening command according to the gate usage requirements and drives the gate body 3 to disengage from the sub-chassis 2 based on the door opening command, and drives the gate body 3 to move to open the gate; or the main control module 10 generates a door closing command according to the gate usage requirements and drives the gate body 3 to move toward the sub-chassis 2 to lock it based on the door closing command, and drives the gate body 3 to move to close the gate.

[0074] The main control module 10 is the core component of the automatic gate control system, which is responsible for generating door opening and door closing instructions and driving the gate body 3 to move. During the door opening process, the main control module 10 generates a door opening instruction according to the gate use requirements, and drives the gate body 3 to disengage from the cooperation with the auxiliary chassis 2 based on the instruction to realize the gate opening. This method can ensure that the gate can be opened in a timely and accurate manner when needed, and improves the response speed and reliability of the gate. During the door closing process, the main control module 10 also generates a door closing instruction according to the gate use requirements, and drives the gate body 3 to move and lock toward the auxiliary chassis 2 based on the instruction to realize the gate closing. This method can ensure that the gate can accurately cooperate with the auxiliary chassis 2 when closing, and improves the accuracy and safety of the gate closing.

[0075] Through this control method, the automatic gate system can flexibly control the opening and closing of the gate according to actual needs, effectively solving the technical problem of the automatic gate control system's door opening and closing control. This solution not only improves the gate's automation level, but also enhances the gate's safety and reliability, which is of great significance to improving the gate's overall performance.

[0076] In order to implement the above technical solution, the main control module 10 can adopt multiple possible implementation methods. Among them, the main control module 10 can be a microprocessor or a microcontroller, equipped with appropriate memory and input and output interfaces. The main control module 10 can implement the control logic of the gate through software programming.

[0077] Specifically, the main control module 10 may include the following key functional modules:

[0078] Demand identification module: used to receive and process signals from various sensors, such as infrared sensors, weight sensors or card readers, to determine the use needs of the gate.

[0079] Instruction generation module: Generates corresponding door opening or closing instructions based on the input of the demand recognition module.

[0080] Drive control module: converts the instruction into a specific motor control signal to drive the gate body 3 to move.

[0081] Position feedback module: through encoder or other position sensors, the position of the gate body 3 is monitored in real time to ensure the accuracy of movement.

[0082] The cooperation between these modules can realize the precise control of the gate. For example, in the process of opening the door, the demand recognition module first detects the door opening request, the instruction generation module then generates the door opening instruction, and the drive control module controls the motor to operate according to the instruction, driving the gate body 3 to separate from the auxiliary chassis 2. At the same time, the position feedback module continuously monitors the position of the gate body 3 to ensure that it moves to the fully open state according to the predetermined trajectory.

[0083] The closing process is similar, but requires more sophisticated control. When the gate body 3 approaches the auxiliary chassis 2, the drive control module will gradually reduce the movement speed of the gate body 3 according to the position feedback information to ensure that it can be smoothly and accurately docked and locked with the auxiliary chassis 2.

[0084] In order to further improve the accuracy and reliability of control, the main control module 10 can adopt a PID (proportional-integral-differential) control algorithm. By adjusting the PID parameters, the best balance between the rapid response and stability of the gate movement can be achieved. For example, in the final stage of the gate body 3 approaching the auxiliary chassis 2, the proportional coefficient can be increased to improve the positioning accuracy, while the differential coefficient can be increased to prevent overshoot.

[0085] In addition, the main control module 10 can also be equipped with fault diagnosis and self-repair functions. By continuously monitoring the working status of each part of the system, the main control module 10 can promptly detect potential problems, such as motor overheating, sensor failure, etc., and take corresponding protective measures. This greatly improves the reliability and safety of the system.

[0086] In practical applications, the technical solution of this application can be implemented as follows:

[0087] Assume a specific automatic gate system, whose main control module 10 uses a 32-bit ARMCortex-M4 microcontroller with an operating frequency of 168MHz, built-in 512KBFlash and 128KBRAM. The system also includes a 24V DC servo motor for driving the gate body 3, a photoelectric encoder for position feedback, and an infrared sensor for detecting the approach of a person or vehicle.

[0088] When the infrared sensor detects an approaching object, the demand recognition module of the main control module 10 will immediately process the signal. Assuming that an approaching vehicle is detected, the instruction generation module will generate a door opening instruction. This instruction contains preset motion parameters, such as a maximum speed of 0.5m / s and an acceleration of 0.2m / s. 2 .

[0089] After receiving this instruction, the drive control module will first give the motor a start pulse, and then continuously adjust the motor's output power according to the PID algorithm. In this process, the position feedback module monitors the position and speed of the gate body 3 in real time through the photoelectric encoder. Assuming that the gate body 3 needs to move 1.5 meters to fully open, the system will maintain a maximum speed of 0.5m / s in the first 1 meter of movement, and start to decelerate in the last 0.5 meters to ensure a smooth stop.

[0090] The entire door opening process may only take 3-4 seconds, greatly improving the traffic efficiency. At the same time, due to the use of precise position control and speed planning, the movement of the gate is smoother, reducing mechanical wear and extending the system life.

[0091] The door closing process is similar, but more cautious. When the vehicle passes, the system will wait for a preset safety time (such as 2 seconds) before starting to close the door. The door closing speed will be slower, and the maximum speed may be only 0.3m / s to ensure safety. In the last 10cm close to full closure, the speed will be further reduced to 0.05m / s to ensure accurate docking with the sub-chassis 2.

[0092] Through such fine control, the technical solution of this application not only solves the problem of automatic gate opening and closing control, but also greatly improves the efficiency, safety and reliability of the system. Compared with the traditional simple opening and closing control, this solution can adapt to various complex usage scenarios, such as fast passage during peak hours, stable operation in bad weather, etc.

[0093] In addition, the technical solution of this application also has good scalability. For example, other functional modules, such as license plate recognition system, intelligent access control management, etc., can be easily integrated to further enhance the intelligence level of the automatic gate system. This flexibility enables this technical solution to adapt to the development needs of future intelligent transportation and smart cities, and has broad application prospects.

[0094] In this regard, the present application further proposes that the gate body 3 is in a slow-speed sensing motion state based on the drive of the main control module 10, and the locking module 20 obtains the movement position of the gate body 3 based on the sensor; when the gate body 3 moves into place, the locking module 20 locks and fixes the gate body 3.

[0095] The existing automatic gate is mainly controlled by a preset control system. The gate sensor recognizes vehicle information and automatically opens and closes the gate, or the operator manually controls the gate opening and closing. Since the existing gate uses an aluminum alloy frame as the main structural material, the gate body 3 has a weak structural rigidity. During the telescopic movement or lifting movement of the gate body 3, it is easily affected by external environmental factors, resulting in the movement deviation of the gate body 3, affecting the accuracy of the gate body 3 closing state, thereby affecting the protective performance of the gate.

[0096] The present application solves the problem that the movement deviation of the gate body 3 affects the accuracy of the closed gate state through the coordinated work of the main control module 10, the sensing module 30 and the locking module 20. The main control module 10 is responsible for driving the gate body 3 to perform slow-speed sensing movement, which helps to reduce movement deviation. The sensing module 30 obtains the movement position of the gate body 3 in real time through the sensor and provides accurate position information for the locking module 20. The locking module 20 locks and fixes the gate body 3 after it moves into place according to the position information provided by the sensing module 30 to ensure the accuracy of the closed gate state.

[0097] Specifically, the main control module 10 can realize the slow-speed sensing motion control of the gate body 3 in a variety of ways. For example, a variable frequency motor can be used as a driving source, and the slow-speed motion of the gate body 3 can be realized by adjusting the speed of the motor. Another way is to use a stepper motor and realize the slow-speed motion by accurately controlling the pulse signal of the stepper motor. In addition, a hydraulic or pneumatic system can also be used to control the movement speed of the gate body 3 by adjusting the pressure.

[0098] The sensors of the sensing module 30 can be of various types, such as photoelectric sensors, Hall sensors or encoders. These sensors are installed at key positions on the motion track of the gate body 3 to monitor the position information of the gate body 3 in real time. The number and installation positions of the sensors can be optimized according to the specific structure and motion characteristics of the gate to ensure that the acquired position information is sufficiently accurate.

[0099] The locking module 20 can be in various forms such as electromagnetic lock, mechanical lock or hydraulic lock. When receiving the gate body 3 arrival signal from the sensing module 30, the locking module 20 will immediately start the locking mechanism. For example, if an electromagnetic lock is used, the electromagnet can be activated by powering on, thereby achieving a secure locking of the gate body 3.

[0100] The collaborative working process between these modules is as follows: First, the main control module 10 drives the gate body 3 to perform slow sensing movement according to the door opening and closing instructions. During the movement, the sensor of the sensing module 30 continuously monitors the position of the gate body 3 and transmits the position information to the locking module 20 in real time. When the sensing module 30 detects that the gate body 3 has moved to the predetermined position, it will immediately send a signal to the locking module 20. After receiving the signal, the locking module 20 quickly starts the locking mechanism to accurately lock the gate body 3.

[0101] This multi-module collaborative working mode effectively solves the problem that the movement deviation of the gate body 3 affects the accuracy of the gate closing state. The main control module 10 controls the gate body 3 to perform slow sensing movement, which greatly reduces the risk of deviation during the movement. The real-time monitoring of the sensing module 30 provides the locking module 20 with an accurate locking time, and the fast response of the locking module 20 ensures that the gate body 3 can be firmly locked in the correct position. This not only improves the protection performance of the gate, but also enhances the reliability and safety of the entire system.

[0102] Specifically, the locking module 20 is provided with a movable locking mechanism, and the locking position of the movable locking mechanism is adjusted based on the position state of the gate body 3 inductively sensed by movement.

[0103] The locking module 20 is provided with an active locking mechanism, which can provide a flexible and adjustable locking function. The active locking mechanism can be adjusted according to the actual movement position of the gate body 3, so as to adapt to possible movement deviations of the gate body 3.

[0104] The locking position of the active locking mechanism is adjusted based on the position state of the gate body 3 motion sensing. This feature enables the locking mechanism to respond to the motion state of the gate body 3 in real time. By sensing the actual position of the gate body 3, the locking mechanism can dynamically adjust its locking position to ensure that the locking operation can be performed accurately even if the gate body 3 moves in a deviation.

[0105] This technical solution realizes adaptive adjustment of the movement deviation of the gate body 3 by setting an adjustable active locking mechanism and combining it with the motion sensing function of the gate body 3. This design can effectively solve the deviation problem that may occur during the movement of the gate body 3 and ensure the accuracy and reliability of the locking operation. Even if the gate body 3 is slightly deflected under the influence of external environmental factors, the active locking mechanism can be adjusted accordingly, thereby ensuring the normal locking function of the gate and improving the overall protection performance of the automatic gate.

[0106] Furthermore, the movable locking mechanism can be implemented in a variety of ways. For example, an electric telescopic mechanism can be used, which can automatically adjust the telescopic length of the locking component according to the sensed position information of the gate body 3. Another implementation method is to use a rotatable locking arm to adapt to different positions of the gate body 3 by adjusting the rotation angle. A magnetically adjustable locking device can also be used to achieve precise adjustment of the locking position by changing the magnetic field strength and direction.

[0107] These different implementations can all work in conjunction with the motion sensing system of the gate body 3. The sensing system can use a photoelectric sensor, a magnetic sensor, or an ultrasonic sensor, etc., to detect the position state of the gate body 3 in real time. Based on the detected position information, the control system can quickly calculate the required locking position adjustment amount and drive the active locking mechanism to make corresponding adjustments.

[0108] Therefore, the technical solution of the present application not only solves the problem of movement deviation of the gate body 3, but also realizes the intelligent and precise locking process. The introduction of the active locking mechanism makes the entire locking system adaptive and can cope with various possible movement deviation situations. This adaptive ability significantly improves the reliability and stability of gate locking.

[0109] Specifically, when the gate body 3 is slightly offset due to external factors during movement, the traditional fixed locking mechanism may not be able to dock accurately, resulting in failed or incomplete locking. The active locking mechanism of the present application can automatically adjust the locking position according to the real-time sensed position of the gate body 3. For example, if the gate body 3 deviates 5 mm to the left, the active locking mechanism will be adjusted 5 mm to the left accordingly to ensure that the locking component can dock with the gate body 3 accurately.

[0110] This dynamic adjustment capability not only improves the success rate of locking, but also can adapt to the use of the gate in different environments. For example, in areas with large temperature changes, the gate body 3 may produce slight position changes due to thermal expansion and contraction, and the active locking mechanism can automatically compensate for these changes to maintain the stability of locking.

[0111] Specifically, the locking module 20 also includes an electromagnetic locking mechanism. When the gate body 3 is locked and matched with the auxiliary chassis 2, the working circuit of the electromagnetic locking mechanism is in a conducting state, and the electromagnetic locking mechanism locks and fixes the gate body 3.

[0112] The existing automatic gate is mainly controlled by a preset control system. The gate sensor recognizes vehicle information and automatically opens and closes the gate, or the operator manually controls the gate opening and closing. Since the existing gate uses an aluminum alloy frame as the main structural material, the gate body 3 has a weak structural rigidity. During the telescopic movement or lifting movement of the gate body 3, it is easily affected by external environmental factors, resulting in the movement deviation of the gate body 3, affecting the accuracy of the gate body 3 closing state, thereby affecting the protective performance of the gate.

[0113] The automatic gate control system of the present application includes a main control module 10, a sensing module 30 and a locking module 20. Among them, the locking module 20 also includes an electromagnetic locking mechanism for locking and fixing the gate body 3. The electromagnetic locking mechanism can be implemented by devices such as electromagnets or electromagnetic valves. When the gate body 3 and the auxiliary chassis 2 complete the locking match, the working circuit of the electromagnetic locking mechanism will be in a conducting state. At this time, the electromagnetic locking mechanism will lock and fix the gate body 3, further enhancing the locking effect of the gate.

[0114] Specifically, the electromagnetic locking mechanism can be arranged inside or outside the auxiliary case 2, corresponding to the corresponding position of the gate body 3. When the gate body 3 moves into place and completes the preliminary locking with the auxiliary case 2, the control system will automatically trigger the working circuit of the electromagnetic locking mechanism to be turned on. The electromagnetic locking mechanism can further fix the gate body 3 by means of magnetic adsorption or mechanical buckle.

[0115] This design provides additional locking force through the electromagnetic locking mechanism, effectively solving the instability problem that may exist after the gate body 3 and the auxiliary chassis 2 are locked together. Therefore, the technical solution of the present application not only enhances the locking strength of the gate, but also improves the automation and intelligence level of the entire system. Compared with the traditional single mechanical locking method, this solution has higher safety and reliability.
