[0003] In existing technology, a mechanical limit point needs to be provided, and the gate will automatically search for it. When the gate opens to the mechanical limit and can no longer move, the gate will remember the limit point of opening and closing the gate through real-time current detection. However, after long-term use, due to the large number of impacts, the rigid collisions cause great wear and tear on the gate's components, and the internal components may also become displaced.

[0050] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0051] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0052] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0054] Existing turnstiles typically have photoelectric sensors on both sides, including transmitters and receivers, for tailgating detection. These sensors can be light curtains, gratings, or infrared beam sensors used on existing turnstiles, designed to detect objects in the turnstile channel using light-sensing principles.

[0055] Please refer to the following: Figures 1 to 4 The gate detection method provided in this application embodiment will now be described. The gate detection method includes the following steps:

[0056] Step S1: The turnstile performs the opening and closing action.

[0057] Step S2: Output the light spot sensing information of the gate in real time;

[0058] Step S3: Detect the real-time status of the gate based on the light spot sensing information;

[0059] Step S4: Calibrate the turnstile.

[0060] It is understandable that the gate detection method makes full use of the light spots on the channel to detect the real-time operating status of the gate and to calibrate the gate.

[0061] Thus, based on the light spot, the principle utilized in this application is that during the swinging process of the gate, the boundary of the gate is equivalent to making circular motion, and when the gate is projected onto the light spot, it is a projection. Since the width of the gate is known, the real-time position of the gate can be determined by using the length of the projection. The real-time operating angle of the gate can be calculated by using the width of the gate and the length of the projection surface.

[0062] In step S1, each time the gate is turned on, the gate is controlled to perform the opening and closing action, which can be used to perform a reset and zeroing action. This action is also performed during debugging to allow the gate to perform zeroing and record the points; to remember the limit points of forward opening, reverse opening, and the points for judging the closed state.

[0063] During the research and development process, the gate detection method of this application can also be used as a debugging method, such as for zeroing and resetting the gate. In daily use, the gate detection method of this application can also serve as a self-maintenance method. That is, each time a pedestrian passes through, the gate's rotation angle and angular velocity at each key node are detected based on the light spot sensing information, thus achieving self-correction.

[0064] Preferably, the door opening and closing action includes a forward rotation state, a reverse rotation state, and a closed state.

[0065] The closed-off state is an important node in the gate's swing process. It is mainly used to determine whether the gate's rotation angle at this node is correct, and to detect whether the gate's position at each important node is accurate.

[0066] During the forward and reverse rotation processes, the gate's linear velocity and angular velocity are mainly used to detect these parameters. This is because, on the one hand, we require the gate to open and close quickly, and on the other hand, we require the gate's force to be gentle to avoid harming pedestrians. Thus, by maintaining reasonable linear and angular velocities, the speed and force of the gate during opening and closing can be kept at a reasonable balance.

[0067] Compared to the mechanical limiting method used in the prior art, the gate detection method of this application makes full use of the existing photoelectric in the gate channel, which can simplify the internal structure of the gate and reduce the component damage caused by rigid collisions. Based on the light spot sensing information, the real-time operating status of the gate can be detected, and the angle of any key node of the gate can be detected. At the same time, the linear velocity and angular velocity of the gate during the forward and reverse opening and closing process can also be detected. It can be used to detect the data of the gate's operating status during testing and debugging, and can also be used to perform self-detection and correction of the gate in actual use.

[0068] In another embodiment of this application, the method for real-time output of the gate's light spot sensing information in step S2 includes the following steps:

[0069] The light spots in the turnstile channel are numbered from 1 to n according to their positional sequence;

[0070] Real-time detection of signal obstruction at each light point;

[0071] Output the number of the blocked light spot, Nmax, and the number of the blocked light spot, Nmin.

[0072] Wherein, the light spot number Nmax is the maximum value of the number among all the light spots that are blocked, and the light spot number Nmin is the minimum value of the number among all the light spots that are blocked.

[0073] It is understandable that since the gate's obstruction of the light spot is continuous, after numbering each light spot with 1 to n, only the two end segment values ​​need to be output. Compared to outputting N consecutive "0" or "1" characters, this can reduce bandwidth requirements and improve the effectiveness of real-time detection.

[0074] Furthermore, the method for detecting the real-time operating status of a gate based on light spot sensing information also includes the following steps:

[0075] If a spot number exists If so, the real-time position of the gate is determined to be in a forward rotation state;

[0076] If a spot number exists If so, the real-time position of the gate is determined to be in a reverse state;

[0077] If no obstruction of the light spot is detected, the real-time position of the gate is determined to be in the closed state.

[0078] Where n is an even number, and the gate is installed at the location numbered... and Between the points of light.

[0079] It is understandable that existing gates are installed at the midpoint of the straight line where all the light spots are located. The above method is applicable when the number of light spots is even. In this way, based on the light spot level, the accuracy error of the gate's real-time operating status detection is minimized.

[0080] In another embodiment, the method for detecting the real-time operating status of a gate based on light spot sensing information further includes the step of:

[0081] If a spot number exists ,and If so, the real-time position of the gate is determined to be in a forward rotation state;

[0082] If a spot number exists ,and If so, the real-time position of the gate is determined to be in a reverse state;

[0083] like If so, the real-time position of the gate is determined to be in the closed state;

[0084] Where n is an odd number, and the gate is installed at the location numbered... At the point of light.

[0085] It is understood that the scenario in this embodiment applies to the case where the gates are all installed at the midpoint of the straight line where all the light spots are located, and the number of light spots is odd. In this way, based on the light spot level, the accuracy error of the real-time operation status detection of the gates is minimized.

[0086] In another embodiment of this application, the method for detecting the real-time operating status of a gate based on light spot sensing information further includes the step of:

[0087] Obtain the spot number Nmax and spot number Nmin when rotating forward or backward;

[0088] Calculate the distance L between two light spots numbered Nmax and Nmin;

[0089] Determine the real-time position rotation angle α of the gate, where the rotation angle α is the angle between the gate and the straight line containing all the light points.

[0090] Furthermore, the method for determining the real-time position rotation angle α of the gate includes:

[0091] Predict the gate width W and the distance S between two adjacent light spots;

[0092] The formula for calculating the rotation angle α is:

[0093] .

[0094] It is understandable that the distance L between the two light spots numbered Nmax and Nmin can be interpreted as the projection of the gate onto the straight line containing all the light spots. Thus, we can obtain... Then, the rotation angle α can be calculated.

[0095] Where n is even, When n is odd, .

[0096] Furthermore, the method for calibrating the turnstile includes the following steps:

[0097] The positions of the gate in the closed state, the forward opening limit state, and the reverse opening limit state are saved from the real-time position rotation angle α.

[0098] Adjust the parameters of the gate drive.

[0099] Understandably, the turnstile actuator has preset operating parameters for the gate to be in the closed, forward-opening, and reverse-opening extreme states. When the real-time position deviates from the preset parameters in the turnstile actuator, correction is required, i.e., updating the turnstile actuator parameters. Updating the turnstile actuator parameters essentially involves updating the motor current in the turnstile. The current output curve required for each gate action is pre-tested, and the parameters are directly matched to the test data during correction, thus achieving automatic correction.

[0100] In another embodiment of this application, step S4, the method for detecting the real-time operating status of the gate based on the light spot sensing information, further includes the step of:

[0101] Obtain the time interval for the change of spot number Nmax or spot number Nmin. ;

[0102] Calculate the real-time linear velocity of the gate. ;

[0103] Determine the maximum value of linear velocity V. max Is it greater than the threshold T?

[0104] Where S is the distance between two adjacent light spots.

[0105] Understandably, the real-time angular velocity ω of the gate can also be calculated based on the linear velocity V, where, If the maximum value of the linear velocity V is V0 max If the value exceeds the threshold T, the gate drive parameters are adjusted to reduce the gate's angular velocity and the gate's striking force.

[0106] Please see Figure 5 This application also provides a gate control system applied to the gate detection method described above. The gate control system includes a control motherboard, a channel driver, a gate, a photoelectric detection component, and a PC setting terminal. The channel driver, the photoelectric detection component, and the PC setting terminal are electrically connected to the control motherboard, and the channel driver is electrically connected to the gate.

[0107] It is understood that the control motherboard can store preset parameters, the PC setting terminal can adjust the preset parameters, the photoelectric detection component can detect the gate position of the gate in real time, and the control motherboard can adjust the gate current through the channel driver, so as to achieve the purpose of automatic correction.

[0108] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
