Description

Technical Field

[0001] This application relates to the field of retractable gates, and more particularly to a retractable gate and its control method, device, storage medium, and electronic equipment. Background Technology

[0002] Retractable gates mainly consist of the gate body, drive motor, slide rails, and control system. They can freely extend and retract, and have a wide interception range. Currently, most shopping malls, museums, and pedestrian streets use retractable gates to control pedestrian access. These gates are remotely controlled, including open, stop, and close modes. However, if the gate's closing status is not constantly monitored during operation, pedestrians may force their way through before it is fully closed, potentially causing the gate to stop prematurely and trapping people, posing a significant safety hazard. Furthermore, when pedestrian traffic far exceeds the gate's opening width, it increases waiting time and can lead to overcrowding. Additionally, if someone places hands, feet, or other foreign objects near the gate before or during operation, it not only obstructs the gate's operation, preventing it from opening and closing properly, but also creates further safety risks.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, 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.

[0035] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0036] According to a first aspect of the embodiments of this application, a control method for a retractable gate is provided, optionally, as follows: Figure 1 As shown, the above method includes:

[0037] S102, when a target object is detected within the first detection range of the telescopic gate, the number of target objects within the first detection range and the target time required for each target object to reach the telescopic gate are obtained, wherein the first detection range is the range within a first preset distance from the telescopic gate;

[0038] S104, Get the opened distance of the retractable gate;

[0039] S106, Based on the target number of target objects, the target time required for each target object to reach the telescopic gate, and the already opened distance, determine the operating speed, operating direction, and operating distance of the telescopic gate;

[0040] S108 controls the operation of the telescopic gate based on its operating speed, direction, and distance.

[0041] Optionally, since current remote control of retractable gates only offers three modes: open, close, and stop, serious safety hazards can easily arise if pedestrians squeeze through the operating gate or if the gate width is much smaller than the pedestrian flow. Therefore, in this embodiment, millimeter-wave radar technology is used to acquire in real time the walking direction, distance, walking speed, and number of people within a first preset distance in front of and behind the retractable gate. This data is transmitted to the retractable gate's control system to filter out people walking towards the gate, calculate the target time required for each person to reach the gate, and the pedestrian flow rate per minute. The opening and closing width of the retractable gate is automatically adjusted based on the pedestrian flow rate, the opening and closing direction is automatically adjusted based on the already opened distance, and the opening and closing speed or emergency stop is controlled based on the target time required for a person to reach the gate. This ensures that people can pass through the retractable gate at a safe distance and avoids waiting and stampedes caused by pedestrian flow exceeding the gate's opening width. Furthermore, when multiple people approach simultaneously, they are grouped together, and the average walking speed of the group is calculated to estimate the walking time, ensuring the safety of all individuals.

[0042] Optionally, in this embodiment, by acquiring the number of target objects and the target time required for each target object to reach the retractable gate in real time, the opening and closing amplitude and speed of the retractable gate are automatically adjusted based on the target number of target objects, the target time required for each target object to reach the retractable gate, and the already opened distance of the retractable gate. This achieves the goal of improving the intelligence level of the retractable gate and solves the technical problem of low intelligence level caused by the need for manual control of the retractable gate.

[0043] As an alternative example, before controlling the operation of the telescopic gate based on its operating speed, direction, and distance, the above method also includes:

[0044] If an obstacle is detected within the second detection range of the retractable gate, the retractable gate is controlled to stop operating. The second detection range is the trajectory range of the retractable gate when it is open.

[0045] Control the retractable gate to issue an alarm and send the alarm information to the management equipment.

[0046] Optionally, if a foreign object check is not performed on the working area of ​​the telescopic gate before its operation, it may damage the gate. Therefore, in this embodiment, millimeter-wave radar technology is used to detect foreign objects inside the telescopic gate and within its opened operating trajectory before and during operation. If a foreign object enters the vulnerable area before or during operation, the telescopic gate will immediately stop operating and issue an alarm, sending the abnormal situation to the management equipment to notify the administrator for coordination and handling. Millimeter-wave radar technology has high resolution and can accurately identify targets entering the telescopic gate's connection points and their corresponding locations. This can prevent injuries to people's hands and feet, and prevent foreign objects from getting stuck and damaging the internal operating structure of the telescopic gate. It also ensures the accuracy and real-time nature of abnormal situation handling, and further ensures the safety of people and property.

[0047] As an optional example, the operating speed, direction, and distance of the retractable gate are determined based on the number of target objects, the target time required for each target object to reach the gate, and the already opened distance.

[0048] Given that the already opened distance is zero and the number of targets is less than or equal to the preset number, obtain the maximum time required for each target object to reach the retractable gate.

[0052] Optionally, in this embodiment, in the first case, i.e., the already opened distance of the telescopic gate is zero, and the number of target objects within the first detection range is less than or equal to a preset number, the ratio of the second preset distance to the maximum time required for each target object to reach the telescopic gate is determined as the operating speed of the telescopic gate. The second preset distance is a reserved distance for the telescopic gate, which can change in real time according to the number of targets. The operating direction of the telescopic gate is determined as the opening direction, and the second preset distance is determined as the operating distance of the telescopic gate.

[0053] As an optional example, the operating speed, direction, and distance of the retractable gate are determined based on the number of target objects, the target time required for each target object to reach the gate, and the already opened distance.

[0054] Given that the already opened distance is zero and the number of targets is greater than the preset number, obtain the average time required for each target object to reach the retractable gate.

The second preset distance is a reserved distance for the telescopic gate, which can change in real time according to the number of targets. The operating direction of the telescopic gate is determined as the opening direction, and the second preset distance is determined as the operating distance of the telescopic gate.

[0059] Optionally, in this embodiment, when the number of target objects within the first detection range is large, groups can be formed based on the distance between each person in the selected group. That is, people with a distance of 1 meter between each other are grouped into the same group, and the average time required for all people in the group to reach the retractable gate is calculated to determine the subsequent opening and closing speed. When multiple groups appear within the first detection range, and the distance between these groups is relatively far, the group walking closer to the retractable gate is processed first.

[0060] As an optional example, the operating speed, direction, and distance of the retractable gate are determined based on the number of target objects, the target time required for each target object to reach the gate, and the already opened distance.

[0061] Given that the already opened distance is greater than zero and less than or equal to the second preset distance, and the number of targets is less than or equal to the preset number, obtain the maximum time required for each target object to reach the retractable gate.

[0062] The ratio of the first distance to the maximum time is determined as the operating speed of the telescopic gate, where the first distance is the difference between the second preset distance and the already opened distance;

[0063] The direction of travel of the retractable gate is determined to be the opening direction;

[0064] The first distance is defined as the operating distance of the retractable gate.

[0065] Optionally, in this embodiment, in the third case, i.e., the already opened distance of the telescopic gate is greater than zero and less than or equal to the second preset distance, and the number of target objects within the first detection range is less than or equal to the preset number, the ratio of the first distance to the maximum time required for each target object to reach the telescopic gate is determined as the operating speed of the telescopic gate. Here, the first distance is the difference between the second preset distance and the already opened distance, and the second preset distance is the reserved distance of the telescopic gate, which can change in real time according to the number of targets. The operating direction of the telescopic gate is determined as the opening direction, and the first distance is determined as the operating distance of the telescopic gate.

[0066] As an optional example, the operating speed, direction, and distance of the retractable gate are determined based on the number of target objects, the target time required for each target object to reach the gate, and the already opened distance.

[0067] If the already opened distance is greater than zero and less than or equal to the second preset distance, and the number of targets is greater than the preset number, obtain the average time required for each target object to reach the retractable gate.

[0070] The first distance is defined as the operating distance of the retractable gate.

[0071] Optionally, in this embodiment, in the fourth case, i.e., the already opened distance of the telescopic gate is greater than zero and less than or equal to the second preset distance, and the number of target objects within the first detection range is greater than the preset number, the ratio of the first distance to the average time required for each target object to reach the telescopic gate is determined as the operating speed of the telescopic gate. Here, the first distance is the difference between the second preset distance and the already opened distance, and the second preset distance is the reserved distance of the telescopic gate, which can change in real time according to the number of targets. The operating direction of the telescopic gate is determined as the opening direction, and the first distance is determined as the operating distance of the telescopic gate.

[0072] As an optional example, the operating speed, direction, and distance of the retractable gate are determined based on the number of target objects, the target time required for each target object to reach the gate, and the already opened distance.

[0073] If the already opened distance is greater than the second preset distance and the number of targets is less than or equal to the preset number, obtain the maximum time required for each target object to reach the retractable gate.

[0074] The ratio of the second distance to the maximum time is determined as the operating speed of the telescopic gate, where the second distance is the difference between the opened distance and the second preset distance;

[0075] The direction of travel of the retractable gate is determined to be the closing direction;

[0076] The second distance is determined as the operating distance of the retractable gate.

[0077] Optionally, in this embodiment, in the fifth case, where the already opened distance of the telescopic gate is greater than the second preset distance, and the number of target objects within the first detection range is less than or equal to the preset number, the ratio of the second distance to the maximum time required for each target object to reach the telescopic gate is determined as the operating speed of the telescopic gate. Here, the second distance is the difference between the already opened distance and the second preset distance, and the second preset distance is the reserved distance of the telescopic gate, which can change in real time according to the number of targets. The operating direction of the telescopic gate is determined to be the closing direction, and the second distance is determined as the operating distance of the telescopic gate.

[0078] As an optional example, the operating speed, direction, and distance of the retractable gate are determined based on the number of target objects, the target time required for each target object to reach the gate, and the already opened distance.

[0079] If the already opened distance is greater than the second preset distance and the number of targets is greater than the preset number, obtain the average time required for each target object to reach the retractable gate.

[0080] The ratio of the second distance to the average time is determined as the operating speed of the telescopic gate, where the second distance is the difference between the opened distance and the second preset distance;

Here, the second distance is the difference between the already opened distance and the second preset distance, which is the reserved distance of the telescopic gate, and this reserved distance can change in real time according to the number of targets. The operating direction of the telescopic gate is determined to be the closing direction, and the second distance is determined as the operating distance of the telescopic gate.

[0084] To illustrate with an example, this application relates to a control method for a retractable gate. It utilizes millimeter-wave radar technology to acquire real-time information on the direction, distance, and speed of people. This data is transmitted to the gate's control system, which identifies individuals walking towards the gate. The system calculates the time required for each person to reach the gate and the flow rate per minute. The gate's opening and closing amplitude is automatically adjusted based on the flow rate. The gate's opening and closing speed or emergency stop is controlled based on the time it takes for individuals to reach the gate. When multiple individuals approach simultaneously, they are grouped, and the average walking speed of the group is calculated to estimate the walking time, ensuring the safety of all individuals. Furthermore, millimeter-wave radar technology has high resolution, accurately identifying targets entering the retractable gate's connection point and their corresponding locations. An emergency braking alarm mode is activated before / during operation, and the anomaly is sent to the remote control with ringing and vibration to notify the administrator for coordination. Currently, retractable gates only offer three remote control modes: open, close, and stop. If pedestrians squeeze through an opening in the operating gate, or if the gate's width is significantly smaller than the flow rate, serious safety hazards can easily arise. Furthermore, failure to inspect the retractable gate's working area for foreign objects before operation can also damage it. Therefore, it is necessary to monitor and control the presence of foreign objects in areas prone to being caught by the retractable gate in a timely manner. Specific implementation methods are as follows: Figure 2 As shown:

[0085] Step 1: Install millimeter-wave radar on the retractable gate and bind it to the control system.

[0086] Step 2: Install the millimeter-wave radar on H1, H2, H3, and H4 of the telescopic gate operator. See [link to specific locations] for details. Figure 3 Wherein, the first preset distance 'a' is the vertical distance detected by the millimeter-wave radar. The millimeter-wave radar and the telescopic gate remote control are then connected to the telescopic gate control system for communication.

[0087] Step 3: Detect foreign objects inside the retractable gate using millimeter-wave radar. The specific process is as follows: Figure 4As shown, when the telescopic gate control system receives the opening / closing command, the millimeter-wave radar H3 prioritizes real-time detection of foreign objects within the second detection range of the telescopic gate, namely the vulnerable area. If a foreign object is detected, the telescopic gate stops operating and issues an alarm. The control system then sends this abnormality information to the telescopic gate remote control, causing it to ring and vibrate, notifying the administrator to handle the situation. If, during operation, H3 detects a foreign object or a person entering the vulnerable area, it immediately stops operating, issues an alarm, and notifies the administrator to handle the situation. If no foreign object is found in the vulnerable area or the abnormality is resolved, the telescopic gate returns to normal operation, and the millimeter-wave radars H1 and H2 continue operating.

[0088] Step 4: Use millimeter-wave radar to detect the time ΔT required for people to reach the retractable gate and the flow of people R.

[0089] Step 5: Millimeter-wave radars H1 and H2 monitor in real time the direction, distance, and speed of people within the first detection range of the retractable gate. People stationary or walking within the detection range whose direction of movement is not within the retractable gate's operating area are eliminated; only people moving towards the retractable gate's opening and closing range are selected. Millimeter-wave radar H4 monitors the distance d from the retractable gate to the endpoint wall and whether there are any people in that area.

[0090] Step Six: Transmit this data information to the control system to calculate the time ΔT required for each selected person to reach the retractable gate, and calculate the corresponding flow rate R per minute.

[0091] Step 7: Set P to the second preset distance that the retractable gate needs to reserve when the pedestrian flow R changes in real time. The gate's opening and closing amplitude will be automatically adjusted according to the changes in pedestrian flow, meaning it will automatically open when the pedestrian flow increases to ensure the safe passage of all personnel. When the distance d = 0 and millimeter-wave radars H1 and H2 detect people, if the pedestrian flow R ≤ 1, the retractable gate will open at V = P / △T (maximum value) and stop operating when d = P; if the pedestrian flow R > 1, the retractable gate will open at V = P / △T (average value) and stop operating when d = P.

[0092] Step 8: When the distance d≤P and the millimeter-wave radars H1 and H2 detect people, if the pedestrian flow R≤1, the retractable gate opens at V=(Pd) / △T (maximum value) and stops operating when d=P; if the pedestrian flow R>1, the retractable gate opens at V=(Pd) / △T (average value) and stops operating when d=P.

[0093] Step 9: When the distance d > P and the millimeter-wave radars H1 and H2 detect people, if the pedestrian flow R ≤ 1, the retractable gate closes at V = (dP) / △T (maximum value) and stops operating when d = P; if the pedestrian flow R > 1, the retractable gate closes at V = (dP) / △T (average value) and stops operating when d = P.

[0094] Step 10: Detect whether there are qualified personnel (walking direction close to the retractable gate) based on millimeter wave H1 and H2. If a person is detected, repeat the loop judgment and calculation until there is no one in the detection area. Then, millimeter wave H4 detects whether there are personnel within a horizontal distance d. If no personnel are detected, close the gate with V = d / T (T is the time required for the retractable gate to close normally).

[0095] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to this application.

[0096] According to another aspect of the embodiments of this application, a control device for a telescopic gate is also provided, such as... Figure 5 As shown, it includes:

[0097] The first acquisition module 502 is used to acquire the number of target objects within the first detection range and the target time required for each target object to reach the retractable gate when a target object is detected within the first detection range of the retractable gate. The first detection range is the range within a first preset distance from the retractable gate.

[0098] The second acquisition module 504 is used to acquire the opened distance of the retractable gate;

[0099] The determination module 506 is used to determine the running speed, running direction and running distance of the telescopic gate based on the target number of target objects, the target time required for each target object to reach the telescopic gate and the already opened distance.

[0100] The first control module 508 is used to control the operation of the telescopic gate according to the running speed, running direction and running distance.

[0101] Optionally, since current remote control of retractable gates only offers three modes: open, close, and stop, serious safety hazards can easily arise if pedestrians squeeze through the operating gate or if the gate width is much smaller than the pedestrian flow. Therefore, in this embodiment, millimeter-wave radar technology is used to acquire in real time the walking direction, distance, walking speed, and number of people within a first preset distance in front of and behind the retractable gate. This data is transmitted to the retractable gate's control system to filter out people walking towards the gate, calculate the target time required for each person to reach the gate, and the pedestrian flow rate per minute. The opening and closing width of the retractable gate is automatically adjusted based on the pedestrian flow rate, the opening and closing direction is automatically adjusted based on the already opened distance, and the opening and closing speed or emergency stop is controlled based on the target time required for a person to reach the gate. This ensures that people can pass through the retractable gate at a safe distance and avoids waiting and stampedes caused by pedestrian flow exceeding the gate's opening width. Furthermore, when multiple people approach simultaneously, they are grouped together, and the average walking speed of the group is calculated to estimate the walking time, ensuring the safety of all individuals.

[0102] Optionally, in this embodiment, by acquiring the number of target objects and the target time required for each target object to reach the retractable gate in real time, the opening and closing amplitude and speed of the retractable gate are automatically adjusted based on the target number of target objects, the target time required for each target object to reach the retractable gate, and the already opened distance of the retractable gate. This achieves the goal of improving the intelligence level of the retractable gate and solves the technical problem of low intelligence level caused by the need for manual control of the retractable gate.

[0104] The second control module is used to control the telescopic gate to stop operating if an obstacle is detected within the second detection range of the telescopic gate before controlling the telescopic gate to operate according to the operating speed, operating direction and operating distance. The second detection range is the trajectory range of the telescopic gate that has been opened.

[0105] The third control module is used to control the retractable gate to issue an alarm and send the alarm information to the management equipment.

[0106] Optionally, if a foreign object check is not performed on the working area of ​​the telescopic gate before its operation, it may damage the gate. Therefore, in this embodiment, millimeter-wave radar technology is used to detect foreign objects inside the telescopic gate and within its opened operating trajectory before and during operation. If a foreign object enters the vulnerable area before or during operation, the telescopic gate will immediately stop operating and issue an alarm, sending the abnormal situation to the management equipment to notify the administrator for coordination and handling. Millimeter-wave radar technology has high resolution and can accurately identify targets entering the telescopic gate's connection points and their corresponding locations. This can prevent injuries to people's hands and feet, and prevent foreign objects from getting stuck and damaging the internal operating structure of the telescopic gate. It also ensures the accuracy and real-time nature of abnormal situation handling, and further ensures the safety of people and property.
