[0018] ④The alarm system is connected to the emergency button, the sound and light alarm mechanism and the electromagnet, and the emergency button triggers the sound and light alarm mechanism and the electromagnet to operate.

[0019] Compared with the prior art, the present invention provides an unattended badminton court management system and components, which have the following beneficial effects:

[0020] 1. Multifunctional intelligent management: The identity recognition method can be selected through the selector. The positioning motor rotates the positioning frame according to the selection, and rotates the corresponding reader to the opening of the storage cavity for identity reading and authentication, so as to achieve precise control of personnel entry and exit, thereby efficiently managing the badminton court. The management chip has a built-in identification system, control system and alarm system, which can control the rotation of the blocking inner rod and the blocking outer rod according to the authentication results, ensuring that only people who have successfully authenticated can enter the venue, thereby improving the intelligent level of venue management.

[0021] 2. Space saving and strong protection: Multiple readers are connected to the door frame through the positioning frame, and only the readers needed are exposed, which reduces the occupied space. At the same time, the unused readers are rotated into the storage cavity for protection, which prolongs the service life of the readers.

[0022] 3. Energy saving and high efficiency: When the positioning frame drives multiple readers to rotate, only the reader rotated to the opening of the storage cavity can be connected to the power supply and the identification system through the electrode sleeve and electrode holder at the lower end, while other readers are disconnected from the power supply, making the positioning frame more energy-efficient.

[0023] 4. Stable connection and high safety: The connecting plug is elastically connected to the inside of the connecting telescopic hole through the plug-in spring. When it is fully inserted into the connecting socket, the locking head can be inserted into the limiting card slot, which improves the connection stability between the blocking inner rod and the blocking outer rod, prevents thieves from pulling the connecting plug out of the connecting socket through objects, and improves safety performance.

[0024] 5. Rapid response to emergencies: When an emergency occurs in the venue, such as fire, earthquake, etc., pressing the emergency button can activate the sound and light alarm mechanism to remind people to evacuate. At the same time, the alarm system connects the electromagnet power supply, attracts the connecting plug and the locking slide rod, and makes the locking head slide out of the limit slot, releasing the lock between the blocking inner rod and the blocking outer rod. The blocking outer rod rotates downward under its own gravity and no longer blocks the door frame, allowing emergency evacuees to pass quickly, thereby improving safety performance.

[0025] 6. Resume after emergency situation is resolved: After the emergency situation is resolved, pull up the emergency button and lift the blocking outer rod. The connecting plug can be inserted into the connecting jack again. The alarm system turns off the sound and light alarm mechanism and disconnects the power supply of the electromagnet. The two locking heads slide smoothly into the limit card slot under the action of the spring to ensure a stable connection between the blocking inner rod and the blocking outer rod, and restore the normal management status of the site.

A selector 6 is provided inside the left side, a storage chamber 7 opening forward is provided at the lower side of the selector 6, and the storage chamber 7 is opened inside the left side of the front end of the door frame 1, a positioning frame 8 in the form of a polygon is rotatably connected inside the storage chamber 7, a motor seat 9 is fixedly connected at the center of the upper end of the storage chamber 7, a positioning motor 10 is clamped inside the lower end of the motor seat 9, a connecting frame 11 is rotatably connected to the lower end of the positioning motor 10 through a rotating shaft, and the connecting frame 11 is fixedly connected to the inside of the positioning frame 8, a plurality of readers 12 are clamped inside the side wall of the positioning frame 8, and a plurality of reading mechanisms are respectively arranged inside the plurality of readers 12 to prevent the inner rod 3 from moving away from the limit rotation. A connecting telescopic hole 17 is provided inside one end of the shaft 2, and a connecting plug 20 is slidably connected inside the connecting telescopic hole 17 near the end of the blocking outer rod 4, and the connecting telescopic hole 17 is connected to the rotating groove of the blocking inner rod 3, and is located on the side of the blocking outer rod 4 near the blocking inner rod 3, and the connecting plug 20 is plugged into the inside of the end of the blocking outer rod 4 near the blocking inner rod 3 through the connecting jack 21, and the connecting jack 21 is provided inside the center of the end of the blocking outer rod 4 near the blocking inner rod 3, and the opening of the connecting jack 21 is arranged in a trumpet shape, and a management chip is built in the door frame 1, and the management chip has a built-in identification system, a control system and an alarm system, and the door frame 1 is arranged at the entrance and exit of the badminton court. Since the connection plug 20 can lock the blocking inner rod 3 and the blocking outer rod 4 by being inserted into the connection telescopic hole 17 and the connection socket 21, the blocking inner rod 3 and the blocking outer rod 4 can be connected as a whole, so that the door frame 1 can be blocked inside by the whole formed by connecting multiple blocking inner rods 3 and multiple blocking outer rods 4 to prevent people from passing through. The door frame 1 can perform identity recognition through the positioning frame 8, and can control whether the multiple blocking inner rods 3 and multiple blocking outer rods 4 rotate according to the recognition result, so as to control the entry and exit of people and further manage the badminton court.

[0039] Preferably, the identity recognition method is selected by the selector 6, and the selector 6 controls the positioning motor 10 to rotate through the control system, rotates the corresponding reader 12 to the opening of the storage cavity 7, and reads the identity through the reading mechanism inside the corresponding reader 12, and authenticates through the identification mechanism. When the authentication is successful, the identification system sends a command to the locking controller 5 to unlock the locking controller 5, so that the limit shaft 2 can rotate freely ninety degrees in one direction at the lower end of the locking controller 5. At this time, people can pass through the inside of the door frame 1 between multiple blocking inner rods 3 and multiple blocking outer rods 4 set at ninety degrees, and after rotating ninety degrees, the locking controller 5 is locked again to prevent unauthenticated people from passing through. When the authentication fails, the identification system will not send a command to the locking controller 5, so that the locking controller 5 remains in a locked state to prevent people who fail the authentication from passing through.

[0040] Preferably, multiple readers 12 are connected to the door frame 1 through the positioning frame 8, and only the readers 12 that need to be used are exposed, which can not only reduce the space occupied by multiple readers 12, but also rotate the unused readers 12 into the storage cavity 7 for protection.

[0041] Preferably, two electrode seats 13 are arranged inside the front side of the inner wall at the lower end of the storage cavity 7, and two electrode sleeves 14 are arranged inside the lower end of the reader 12. Electrode heads 15 are clamped inside the lower ends of the two electrode sleeves 14, and electrode springs 16 are arranged on the upper ends of the two electrode heads 15, and are elastically connected to the lower ends of the electrode sleeves 14 through the two electrode springs 16, and the two electrode heads 15 can be clamped inside the upper ends of the two electrode seats 13 respectively. When the positioning frame 8 drives the multiple readers 12 to rotate, the reader 12 rotated to the opening of the storage cavity 7 can pass through the lower The two electrode sleeves 14 at the ends are connected to the two electrode seats 13 inside the inner wall of the lower end of the storage cavity 7, so that the reader 12 rotated to the opening of the storage cavity 7 is connected to the power supply and connected to the identification system, while the other multiple readers 12 rotated to the inside of the storage cavity 7 are disconnected from the power supply, making the positioning frame 8 more energy-efficient, and the electrode sleeve 14 at the lower end of the reader 12 rotated to the opening of the storage cavity 7 can be clamped with the electrode seat 13 through the elastically connected electrode head 15, which can not only make the connection between the electrode seat 13 and the electrode sleeve 14 more stable, but also limit the position of the position reader 12.

[0042] Preferably, an electromagnet 18 is arranged inside the end of the connecting telescopic hole 17 near the limit rotating shaft 2, and a plug spring 19 is arranged at one end of the electromagnet 18 near the blocking outer rod 4, and a connecting plug 20 is arranged at one end of the plug spring 19 near the blocking outer rod 4. The connecting plug 20 is elastically connected to the inside of the connecting telescopic hole 17 through the plug spring 19, and a limit card groove 22 is arranged inside the inner wall of the connecting plug 21, and the limit card groove 22 is located outside the connecting plug 20, and the inside of the connecting plug 20 is opened at the central axis. There is a locking slide hole 23, a locking slide rod 24 is slidably connected inside the locking slide hole 23, a locking baffle ring 25 is fixedly connected to the outside of the locking slide rod 24 near the blocking outer rod 4, the locking baffle ring 25 is slidably connected to the inside of the locking slide hole 23, a locking spring 26 is arranged at the end of the locking baffle ring 25 away from the blocking outer rod 4, and the locking slide rod 24 and the locking baffle ring 25 are elastically connected to the inside of the locking slide hole 23 through the locking spring 26, and the upper and lower ends of the locking slide hole 23 are connected to the inside of the blocking outer rod 4. The locking telescopic hole 27 has a locking head 28 slidably connected inside the locking telescopic hole 27, and the locking head 28 is inserted into the limiting card slot 22 at one end away from the locking sliding hole 23, and fits on the outside of the locking slide rod 24 close to the blocking outer rod 4. An unlocking ring 29 is fixedly connected to the locking head 28 on the side close to the locking sliding hole 23. An unlocking spring 30 is provided at one end of the unlocking ring 29 away from the locking sliding hole 23, and the locking head 28 and the unlocking ring 29 are elastically connected to the locking telescopic hole 27 through the unlocking spring 30. Inside the hole 27, when the connecting plug 20 is fully inserted into the connecting socket 21, the locking head 28 can be inserted into the limiting slot 22 by pushing the locking slide bar 24, thereby limiting the position between the connecting plug 20 and the connecting socket 21, which can not only improve the connection stability between the connecting plug 20 and the connecting socket 21, and improve the connection stability between the blocking inner rod 3 and the blocking outer rod 4, but also prevent the thief from pulling the connecting plug 20 out of the connecting socket 21 through objects, thereby improving the safety performance.

[0043] Preferably, when an emergency occurs in the badminton court, such as a fire, earthquake or other emergency situation, the emergency button is pressed, and the emergency button activates the sound and light alarm mechanism through the alarm system, so that the sound and light alarm mechanism emits an alarm sound and an alarm light to remind people in the badminton court to evacuate. At the same time, the alarm system connects the power supply of the electromagnet 18 to allow the electromagnet 18 to generate a magnetic force. The electromagnet 18 attracts the connecting plug 20 and the locking slide bar 24 toward one end of the limit rotating shaft 2 through the magnetic force. Since the connecting plug 20 is restricted by the limit card slot 22 and the locking head 28, the connecting plug 20 first remains stationary, and the locking slide bar 24 slides toward the electromagnet 18 and slides out between the two locking heads 28. Under the action of the unlocking spring 30, the locking head 28 slides into the locking slide hole 23 and slides out of the limiting slot 22. At this time, the connecting plug 20 is no longer restricted by the limiting slot 22 and the locking head 28. The end of the connecting plug 20 close to the blocking outer rod 4 slides into the trumpet-shaped opening of the connecting jack 21 under the attraction of the electromagnet 18, thereby releasing the lock between the blocking inner rod 3 and the blocking outer rod 4, allowing the blocking outer rod 4 to rotate inside the blocking inner rod 3. The blocking outer rod 4 rotates downward under the action of its own gravity and is no longer blocked inside the door frame 1, so that emergency evacuees can quickly pass through the door frame 1 and quickly evacuate from the badminton court, thereby improving safety performance.

[0044] Preferably, when the emergency situation is resolved, the emergency button is pulled up, and the blocking outer rod 4 is lifted upward, so that the connecting plug 20 is again inserted into the trumpet-shaped opening of the connecting jack 21. At this time, the alarm system turns off the sound and light alarm mechanism and disconnects the power supply of the electromagnet 18. The electromagnet 18 no longer generates magnetic force. Since the connecting plug 20 is located inside the trumpet-shaped opening of the connecting jack 21, the two locking heads 28 are squeezed by the inner wall of the opening of the connecting jack 21, so that the locking slide bar 24 cannot slide between the two locking heads 28, making The connecting plug 20 and the two locking heads 28 can slide smoothly into the connecting hole 21 under the action of the plug spring 19 to limit the position between the blocking inner rod 3 and the blocking outer rod 4. At the same time, the two locking heads 28 slide to the position of the limit slot 22 and are no longer restricted by the inner wall of the connecting hole 21. The locking slide rod 24 can slide smoothly between the two locking heads 28 under the action of the locking spring 26, and squeeze the two locking heads 28 into the limit slot 22 to ensure the stable connection between the blocking inner rod 3 and the blocking outer rod 4.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
