Description

Technical Field

[0001] The present invention belongs to the technical field of information display, and specifically relates to an intelligent LED electronic information display screen. Background Art

[0002] An electronic display screen is a screen that displays information in public places (such as hospitals, service halls, squares, waiting places, etc.), can display pictures or text and other information as needed, and can also play voice messages. In order to allow people to clearly see the displayed content, the electronic display screen is generally firmly hung on a prominent wall.

[0003] The currently used electronic display screen has a fixed position. When a person on the side is far away from the display screen, the person cannot clearly see the content in the display screen. In order to see the content of the display screen clearly, one needs to stare at the display screen for a long time, increasing the probability of eye discomfort, or walk to the front of the display screen to watch, which brings inconvenience to people. Summary of the Invention

[0004] In order to make up for the deficiencies of the prior art, the present invention provides an intelligent LED electronic information display screen. The present invention mainly solves the problem that due to the fixed position of the currently used electronic display screen, when a person on the side is far away from the display screen, one needs to stare at the display screen for a long time, increasing the probability of eye discomfort, or walk to the front of the display screen to watch, which brings inconvenience to people.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: The present invention provides an intelligent LED electronic information display screen, which includes a display screen body, a connecting frame, a rotating component, and a controller; one end of the connecting frame is connected to the wall; the other end of the connecting frame is provided with the display screen body; the display screen body is used to display waiting information; the display screen body is rotatably connected to the connecting frame; the rotating component is arranged on the connecting frame; the rotating component is connected to the connecting frame; the rotating component is used to realize the rotation of the display screen body; the controller is arranged on the connecting frame; the controller is fixedly connected to the connecting frame; the rotating component is electrically connected to the controller; the controller is internally provided with a face recognition module, a position acquisition module, a first calculation module, an execution module, a reset module, a second calculation module, a timing module, and a display module; the face recognition module is used to capture the facial contour of the waiting person who is gazing at the display screen body; the position acquisition module is used to acquire the position information of the waiting person who is gazing at the display screen body; the first calculation module is used to calculate the first rotation angle required for the display screen body to rotate from the initial position to face the waiting person; the execution module is used to control the rotating component to rotate the display screen body by the first rotation angle; the reset module is used to return the display screen body to the initial position; the timing module is used to record the duration after the display screen body rotates to face the waiting person; the second calculation module is used to calculate the reset angle required for the display screen body to directly return to the initial position from the current position; the display module is used to display the waiting information of the waiting person.

[0006] When working, the display module projects the waiting information of all waiters on the display screen body. The face recognition module scans the facial contours of the waiters in the area in front of the display screen body. When a waiter wants to view the waiting information on the display screen body and gazes at the display screen body, the face recognition module obtains the conclusion that the waiter at this place (denoted as the first waiter) needs to view the waiting information on the display screen body, thereby generating a position acquisition signal and transmitting it to the position acquisition module. After receiving the signal, the position acquisition module obtains the position information of the first waiter and transmits it to the first calculation module. Then, the first calculation module uses a mathematical formula to calculate the position information of the first waiter, thereby obtaining the first rotation angle required for the display screen body to rotate from the current position to face the first waiter, and transmits the first rotation angle to the execution module. After receiving the first rotation angle information, the execution module controls the rotating component to work, and then makes the display screen body rotate towards the first waiter according to the first rotation angle through the rotating component, so that the display screen body faces the first waiter, which is convenient for the first waiter to clearly see the waiting information on the display screen body, thereby improving the convenience of the display screen body; after the execution module rotates the display screen body to face the first waiter, it generates a timing signal and transmits it to the timing module. Then, the timing module records the duration during which the display screen body faces the first waiter. When the duration is greater than the set time, the timing module stops timing and obtains the conclusion that the first waiter has finished obtaining information. At the same time, it generates a reset signal and transmits it to the reset module. After receiving the reset signal, the reset module makes the rotating component work, and then makes the display screen body rotate in the reverse direction according to the first rotation angle, so that the display screen body returns to its initial position;When the face recognition module recognizes again that the next waiting person (denoted as the second waiting person) is looking at the display screen body, and the duration recorded by the timing module is greater than the set time, the controller continues to work in the above manner. When the duration recorded by the timing module is less than the set time, the position acquisition module acquires the position information of the second waiting person and transmits it to the first calculation module. Then, the first calculation module uses a mathematical formula to calculate the position information of the second waiting person, so as to obtain the second rotation angle required for the display screen body to rotate from the current position to face the second waiting person, and transmits the second rotation angle to the execution module. At the same time, the timing module continues to count. When the duration is greater than the set time, the timing module stops counting and concludes that the first waiting person has finished obtaining information. At the same time, it generates a signal for re-rotation and transmits it to the execution module. When the execution module receives the second rotation angle information and the signal for re-rotation, it controls the rotating component to work. Then, through the rotating component, the display screen body rotates towards the second waiting person according to the second rotation angle, so that the display screen body faces the second waiting person, which is convenient for the second waiting person to view the waiting information, and avoids the display screen body returning to the initial position after one waiting person finishes obtaining information and then rotating to face the next waiting person for them to obtain information, thereby reducing the waiting time of the next waiting person and improving the convenience of the display screen body. After the execution module rotates the display screen body to face the second waiting person, it generates a timing signal and transmits the timing signal to the timing module. Then, the timing module records the duration of the display screen body facing the second waiting person. When the duration is greater than the set time, the timing module stops counting and concludes that the second waiting person has finished obtaining information. At the same time, it generates a reset signal and transmits it to the reset module and the second calculation module. After receiving the reset signal, the second calculation module calculates the first rotation angle and the second rotation angle, so as to calculate the reset angle required for the display screen body to rotate from facing the second waiting person to the initial position, and transmits it to the reset module. After receiving the reset signal and the reset angle, the reset module makes the rotating component work, so that the display screen body rotates according to the reset angle, so that the display screen body returns to the initial position, and avoids the display screen body having to be reset multiple times to return to the initial position, which is convenient for the reset of the display screen body. When two or more waiting persons are looking at the display screen body at the same time, the face recognition module generates extraction signals successively according to the distance of the waiting persons from the display screen body, so that the display screen body faces the waiting persons in turn according to the distance, which avoids the waiting persons staring at the display screen body for a long time, reduces the probability of eye discomfort of the waiting persons, and at the same time avoids the waiting persons walking to the front of the display screen body to watch, which is convenient for the waiting persons to see the display screen body clearly in place and improves the convenience of the display screen.

[0007] Preferably, an information entry module, a storage module, a download module, a database module, a simplification module, and an upload module are further provided in the controller; a face scanning unit is provided in the face recognition module; the face scanning unit is used to scan the facial image of the waiting person; the information entry module is used to enter the identity information and matters to be handled of the waiting person; the database module is used to store the precautions and relevant materials corresponding to specific matters; the download module is used to download the corresponding precautions and relevant materials from the database module according to the matters to be handled by the waiting person; the storage module is used to record the identity information, facial image, matters to be handled, and precautions of the waiting person; the upload module is used to transfer the information of the waiting person to the window staff; the simplification module is used to refine and simplify the information of the waiting person.

[0008] When the waiting person conducts information registration, the waiting person enters his / her identity information and matters to be handled according to the requirements of the information entry module. Subsequently, the information entry module transfers the identity information and matters to be handled of the waiting person to the storage module. At the same time, the information entry module generates a download signal and transfers it to the face recognition module and the download module. After receiving the download signal, the face recognition module makes the face scanning unit work. Then, the face scanning unit scans the face of the waiting person, forms a facial image, and transfers it to the storage module. After receiving the download signal, the download module extracts the corresponding precautions (such as various materials required for handling social security business, how to protect oneself according to the condition when seeing a doctor, and taboos of the condition, etc.) from the database module according to the matters to be handled by the waiting person, and transfers them to the storage module. The storage module stores the information of the waiting person, namely the facial image, identity information, matters to be handled, and precautions. Subsequently, the upload module transfers the materials of the waiting person to the corresponding window staff, which is convenient for the window staff to make an overall plan for subsequent work, optimize the work process, improve work efficiency, and shorten the waiting time of the waiting person; at the same time, the simplification module refines the materials of the waiting person and transfers them to the display module for display on the display screen body. By simplifying the materials of the waiting person through the simplification module, the amount of materials to be displayed is reduced, the screen size occupied by the materials is reduced, the number of waiting persons that the display screen body can display is increased, and more waiting persons can view the waiting information.

[0009] Preferably, the controller further includes a gesture recognition module, a first extraction module, a second extraction module, a first comparison module, a transmission module, and a cache module; the gesture recognition module is used to recognize the gestures of the waiters; the first extraction module is used to extract the facial images of the waiters from the face scanning unit; the cache module is used to temporarily store the information of the waiters; the first comparison module is used to compare the facial images of the waiters with the facial images in the storage module; the second extraction module is used to extract the specific information of the waiters from the cache module; the transmission module is used to transmit the specific information of the waiters to the display module.

[0010] When the display screen body faces the waiter directly, the waiter makes a gesture to view the detailed waiting information with his hand. Thus, the gesture recognition module recognizes the gesture of the waiter, draws the conclusion that the waiter needs to view the detailed waiting information, generates an extraction signal and transmits it to the first extraction module. The first extraction module receives the signal and extracts the facial image of the waiter from the face scanning unit, and transmits the facial image of the waiter to the first comparison module. Then, the first comparison module compares the facial image with the facial images in the storage module one by one. When the facial image of a certain waiter matches the facial image, the first comparison module stops the comparison, generates a transmission signal, and transmits the transmission signal to the transmission module. After receiving the transmission signal, the transmission module transmits the specific information of this waiter in the storage module to the display module. Then, the specific information of this waiter is displayed on the display screen body, which is convenient for the waiter to view the precautions for handling his own matters, convenient for the user to make preparations in advance, and improves the convenience of the display screen. At the same time, the transmission module transmits the information of this waiter to the cache module. When the face scanning unit scans the facial image of this waiter again, the face scanning unit generates a signal for re-extraction and transmits the re-extraction signal to the second extraction module. Then, the second extraction module extracts the specific information of this waiter from the cache module and transmits it to the display module, which is convenient for the waiter to view his own information on the display screen body again, saves the waiting time of the waiter, and improves the convenience of the display screen.

[0011] Preferably, the controller further includes a third extraction module, a fourth extraction module, a second comparison module, and a broadcast module; the third extraction module is used to extract the facial image of the waiter from the face scanning unit; the second comparison module is used to compare the facial image of the waiter with the facial images in the storage module; the fourth extraction module is used to extract the first rotation angle or the reset angle of the waiter from the storage module; the broadcast module is used to broadcast the name of the waiter.

[0012] After receiving the reset signal, the reset module transfers the corresponding first rotation angle or reset angle of the waiting person to the storage module. At the same time, the reset module generates a storage extraction signal and transfers it to the third extraction module. The third extraction module extracts the facial image of the waiting person from the face scanning unit after receiving the signal, and transfers the facial image of the waiting person to the second comparison module. Then, the second comparison module compares the facial image with the facial images in the storage module one by one. When the facial image of a certain waiting person matches this facial image, the second comparison module stops the comparison and generates a storage signal, and transfers the storage signal to the storage module. Then, the storage module stores the first rotation angle or reset angle of this waiting person into the specific information of this waiting person. Before the broadcast module broadcasts the name of this waiting person, the broadcast module transfers the identity information of the waiting person to be broadcast to the fourth extraction module. Then, the fourth extraction module extracts the first rotation angle or reset angle of this waiting person from the storage module and transfers it to the execution module, so that the controller works, and then makes the display screen body rotate according to the first rotation angle or reset angle, so that the display screen body faces this waiting person, thereby increasing the probability of attracting the attention of the waiting person, and then increasing the probability of the waiting person viewing the display screen body. Thus, in cooperation with the voice broadcast, the waiting person knows that they are being called, thereby reducing the probability of the waiting person ignoring the call number, and then improving the convenience of the display screen.

[0013] Preferably, the rotating component includes a connecting shaft, a driving shaft, a connecting piece and a first motor; the upper and lower ends of the connecting frame are symmetrically provided with the connecting shafts; the connecting shafts are rotatably connected to the connecting frame; one of the connecting shafts is fixedly connected to the upper end of the display screen body; the other connecting shaft is fixedly connected to the lower end of the display screen body; the driving shaft is arranged on the connecting frame; the driving shaft is rotatably connected to the connecting frame; the connecting shaft and the driving shaft are connected by the connecting piece; the connecting piece is made of a flexible shell torsion material; one end of the connecting piece is connected to the connecting shaft; the other end of the connecting piece is connected to the driving shaft; the first motor is fixedly connected to the connecting frame; the rotating shaft of the first motor is connected to the driving shaft through a first transmission component; the first motor is electrically connected to the controller.

[0014] Due to the large area of the display screen body, it has a large inertia. When the display screen body suddenly rotates, the display screen body will remain stationary under the action of inertia (when the display screen body suddenly stops rotating, the display screen body will continue to rotate under the action of inertia), thereby increasing the impact on the display screen body. Since there are a large number of electronic components inside the display screen body and the display screen body rotates frequently, the probability of damage to the display screen body is increased. By setting a connecting member (a part such as a spring that can twist and transmit torque), the display screen body starts to rotate slowly or stops rotating slowly, thereby reducing the impact on the display screen body, reducing the probability of damage to the display screen body, and improving the reliability of the display screen body; because there are many people in public places, when a waiting person touches the display screen body, the display screen body will rotate, thereby reducing the impact between the display screen body and the waiting person, reducing the pain of the waiting person, and at the same time reducing the probability of damage to the display screen body.

[0015] Preferably, a fan is provided on one side of the display screen body close to the connecting frame; the fans are evenly spaced up and down; the rotating shaft of the fan is horizontally arranged; the rotation of the fan is parallel to the side surface of the display screen body; the rotating shafts of all the fans rotate synchronously; a second gear is provided on the connecting frame; the second gear is fixedly connected to the connecting frame; an installation seat is provided on the display screen body; the installation seat is fixedly connected to the display screen body; a first rotating shaft is provided on the installation seat; the first rotating shaft is rotatably connected to the installation seat; a first gear is provided at one end of the first rotating shaft; the first gear is fixedly connected to the first rotating shaft; the first gear meshes with the second gear; a first bevel gear is provided at the other end of the first rotating shaft; the first bevel gear is fixedly connected to the first rotating shaft; a second rotating shaft is provided on the installation seat; the second rotating shaft is rotatably connected to the installation seat; a second bevel gear is provided on the second rotating shaft; the second bevel gear is fixedly connected to the second rotating shaft; the second bevel gear meshes with the first bevel gear; the rotating shaft of the fan close to the second rotating shaft is connected to the second rotating shaft through a second transmission assembly.

[0016] Due to the large area of the display screen body, when one side of the display screen body approaches the wall, the air on the back of this side is squeezed, thereby increasing the air pressure received on the back of this side. At the same time, the air pressure on the front of this side decreases, thereby causing a resistance force in the direction away from the wall to act on this side of the display screen body. At the same time, the other side moves away from the wall, thereby increasing the air pressure on the face of this side and decreasing the air pressure on the back. Thereby, a resistance force in the direction towards the wall acts on this side of the display screen body. Thereby, air resistance forces act on both sides of the display screen body, thereby hindering the rotation of the display screen body. When the display screen body rotates, the display screen body drives the first gear to move. Also, because the first gear meshes with the second gear, it drives the first gear to rotate around its own axis, thereby driving the first rotating shaft to rotate, thereby driving the first bevel gear to rotate, thereby driving the second bevel gear to rotate, thereby driving the second rotating shaft to rotate, thereby driving the rotation of the shaft of a fan through the second transmission component, thereby driving the rotation of the shafts of all fans, thereby driving the rotation of all the fans, thereby generating a suction force on the air on the back of the display screen body, thereby causing the air on the back of the side approaching the wall to move to the other side, thereby reducing the air pressure on the back of the side approaching the wall, thereby reducing the pressure difference between the back and the face of the side approaching the wall, thereby reducing the resistance of this side of the display screen body approaching the wall, thereby reducing and increasing the air pressure on the back of the side away from the wall at the same time, thereby reducing the pressure difference between the face and the back of the side away from the wall, thereby reducing the resistance of this side of the display screen body away from the wall, thereby reducing the resistance received when the display screen body rotates, thereby realizing the reliable rotation of the display screen body, and thereby improving the reliability of the display screen during operation.

[0017] Preferably, a baffle is provided on one side of the display screen body close to the connecting frame; the baffles are evenly spaced up and down; the baffle is fixedly connected to the display screen body; the fans are arranged between two adjacent baffles.

[0018] By providing the baffle, the air is guided, thereby increasing the stability of the air flow, thereby effectively reducing the resistance received when the display screen body rotates, thereby realizing the reliable rotation of the display screen body, and thereby improving the reliability of the display screen during operation.

[0019] Preferably, three cameras are provided on the display screen body; the cameras are communicated with the face recognition module; one of the cameras is arranged directly below the display screen body; the other two cameras are respectively arranged on the left and right sides of the display screen body; a second synchronous pulley is provided on the connecting frame; the second synchronous pulleys are arranged at intervals; the two second synchronous pulleys are fixedly connected; one of the second synchronous pulleys is fixedly connected with the connecting frame; third rotating shafts are provided on both sides of the display screen body; the third rotating shafts are rotatably connected with the display screen body; third synchronous pulleys are provided on the third rotating shafts; the third synchronous pulleys are fixedly connected with the third rotating shafts; the second synchronous pulley and the third synchronous pulley are connected by a first synchronous belt; the camera is arranged on the third rotating shaft; the camera is fixedly connected with the third rotating shaft; the working surface diameters of the first synchronous pulley and the second synchronous pulley are equal.

[0020] When the display screen body rotates too much to one side, the camera on the other side cannot scan the facial image of the waiting person. At this time, the display screen body needs to return to the initial position, or the facial image of the waiting person can be recognized only during the process of returning to the initial position, thereby increasing the waiting time of the waiting person. By arranging cameras at both ends of the display screen body, when the display screen body rotates a certain angle to one side, the display screen body drives the first synchronous belt to rotate around the axis of the driving shaft. Also, because the second synchronous pulley does not move, the first synchronous belt moves a certain distance, thereby driving the third synchronous pulley to rotate in the reverse direction by a certain angle, and then driving the camera to rotate in the reverse direction by a certain angle, so that the camera is always directly opposite the left and right sides of the initial position of the display screen body, which is convenient for the camera to capture the facial image of the waiting person on the side, thereby reducing the waiting time of the waiting person on the side and improving the convenience of the display screen.

[0021] Preferably, the camera is a wide-angle lens.

[0022] By setting the wide-angle lens, the camera can capture the facial image of the waiting person in the distance, and the display screen body rotates to the angle directly opposite the waiting person in the distance, which is convenient for the waiting person in the distance to view the waiting information and improves the applicability of the display screen.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. In the present invention, the display module projects the waiting information of all waiters onto the display screen body. The face recognition module scans the facial contours of the waiters in the area in front of the display screen body. When a waiter wants to view the waiting information on the display screen body and gazes at the display screen body, the face recognition module concludes that the waiter at that location needs to view the waiting information on the display screen body, thereby generating a position acquisition signal and transmitting it to the position acquisition module. After receiving the signal, the position acquisition module acquires the position information of the first waiter and transmits it to the first calculation module. Then, the first calculation module uses a mathematical formula to calculate the position information of the first waiter, thereby obtaining the first rotation angle required for the display screen body to rotate from the current position to face the first waiter, and transmits the first rotation angle to the execution module. After receiving the first rotation angle information, the execution module controls the rotating component to work, and then rotates the display screen body towards the first waiter according to the first rotation angle through the rotating component, so that the display screen body faces the first waiter, which is convenient for the first waiter to clearly see the waiting information on the display screen body, thereby improving the convenience of the display screen body; after the execution module rotates the display screen body to face the first waiter, it generates a timing signal and transmits it to the timing module. Then, the timing module records the duration of the display screen body facing the first waiter. When the duration is greater than the set time, the timing module stops timing and concludes that the first waiter has finished obtaining information. At the same time, it generates a reset signal and transmits it to the reset module. After receiving the reset signal, the reset module makes the rotating component work, and then rotates the display screen body in the reverse direction according to the first rotation angle, so that the display screen body returns to the initial position; when the face recognition module recognizes that the next waiter is gazing at the display screen body again and the duration recorded by the timing module is greater than the set time, the controller continues to work in the above manner. When the duration recorded by the timing module is less than the set time, the position acquisition module acquires the position information of the second waiter and transmits it to the first calculation module. Then, the first calculation module uses a mathematical formula to calculate the position information of the second waiter, thereby obtaining the second rotation angle required for the display screen body to rotate from the current position to face the second waiter, and transmits the second rotation angle to the execution module. At the same time, the timing module continues to time. When the duration is greater than the set time, the timing module stops timing and concludes that the first waiter has finished obtaining information. At the same time, it generates a signal for re-rotation and transmits it to the execution module. When the execution module receives the second rotation angle information and the signal for re-rotation, it controls the rotating component to work, and then rotates the display screen body towards the second waiter according to the second rotation angle through the rotating component, so that the display screen body faces the second waiter, which is convenient for the second waiter to view the waiting information, thereby avoiding the situation that after a waiter finishes obtaining information and the display screen body returns to the initial position and then rotates to face the next waiter for him to obtain information, thereby reducing the waiting time of the next waiter and improving the convenience of the display screen body;The execution module causes the display body to rotate to face the second waiting person and then generates a timing signal, and transmits the timing signal to the timing module. Then, the timing module records the duration during which the display body faces the second waiting person. When the duration is greater than the set time, the timing module stops timing and concludes that the second waiting person has finished obtaining information. At the same time, it generates a reset signal and transmits it to the reset module and the second calculation module. After receiving the reset signal, the second calculation module calculates the first rotation angle and the second rotation angle, thereby calculating the reset angle required for the display body to rotate from facing the second waiting person to the initial position, and transmits it to the reset module. After receiving the reset signal and the reset angle, the reset module makes the rotating component work, thereby causing the display body to rotate according to the reset angle, and then causing the display body to return to the initial position, thereby avoiding the display body having to be reset multiple times to return to the initial position, and thus facilitating the reset of the display body; when two or more waiting persons are looking at the display body at the same time, the face recognition module generates extraction signals successively according to the distances of the waiting persons from the display body, thereby causing the display body to face the waiting persons in turn according to the distances, thereby avoiding the waiting persons staring at the display body for a long time, thereby reducing the probability of eye discomfort of the waiting persons, and at the same time avoiding the waiting persons walking to the front of the display body to watch, thereby facilitating the waiting persons to clearly see the display body in place, and thus improving the convenience of the display screen.

[0025] 2. When a waiting person registers information in the present invention, the waiting person inputs his / her identity information and the matters to be handled according to the requirements of the information input module. Subsequently, the information input module transmits the identity information and the matters to be handled of the waiting person to the storage module. At the same time, the information input module generates a download signal and transmits it to the face recognition module and the download module. After receiving the download signal, the face recognition module makes the face scanning unit work. Then, the face scanning unit scans the face of the waiting person, thereby forming a face image and transmitting it to the storage module. After receiving the download signal, the download module extracts the corresponding precautions from the database module according to the matters to be handled by the waiting person and transmits them to the storage module. The storage module stores the information of the waiting person, namely the face image, identity information, matters to be handled, and precautions. Subsequently, the upload module transmits the materials of the waiting person to the corresponding window staff, thereby facilitating the window staff to make an overall plan for the subsequent work, thereby optimizing the work process, thereby improving the work efficiency, and thus shortening the waiting time of the waiting person; at the same time, the simplification module refines the materials of the waiting person and transmits them to the display module for display on the display body. By simplifying the materials of the waiting person through the simplification module, the amount of materials to be displayed is reduced, thereby reducing the screen size occupied by the materials, thereby increasing the number of waiting persons that the display body can display, and thus allowing more waiting persons to view the waiting information.

[0026] 3. When the display screen body faces the waiting person in the present invention, the waiting person makes a gesture to view detailed waiting information with his hand, so that the gesture recognition module recognizes the gesture of the waiting person, draws the conclusion that the waiting person needs to view detailed waiting information, generates an extraction signal and transmits it to the first extraction module. The first extraction module receives the signal, extracts the facial image of the waiting person from the face scanning unit, and transmits the facial image of the waiting person to the first comparison module. Then, the first comparison module compares the facial image with the facial images in the storage module one by one. When the facial image of a certain waiting person coincides with this facial image, the first comparison module stops comparing, generates a transmission signal, and transmits the transmission signal to the transmission module. After receiving the transmission signal, the transmission module transmits the specific information of this waiting person in the storage module to the display module, and then the specific information of this waiting person is displayed on the display screen body, which is convenient for the waiting person to view the precautions for the matters he handles, convenient for the user to make preparations in advance, and improves the convenience of the display screen. At the same time, the transmission module transmits the information of this waiting person to the cache module. When the face scanning unit scans the facial image of this waiting person again, the face scanning unit generates a signal for re-extraction and transmits the re-extraction signal to the second extraction module. Then, the second extraction module extracts the specific information of this waiting person from the cache module and transmits it to the display module, which is convenient for the waiting person to view his own information on the display screen body again, saves the waiting time of the waiting person, and improves the convenience of the display screen.

[0027] 4. After receiving the reset signal in the present invention, the reset module transmits the first rotation angle or reset angle corresponding to this waiting person to the storage module. At the same time, the reset module generates a storage extraction signal and transmits it to the third extraction module. The third extraction module receives the signal, extracts the facial image of the waiting person from the face scanning unit, and transmits the facial image of the waiting person to the second comparison module. Then, the second comparison module compares the facial image with the facial images in the storage module one by one. When the facial image of a certain waiting person coincides with this facial image, the second comparison module stops comparing, generates a storage signal, and transmits the storage signal to the storage module. Then, the storage module stores the first rotation angle or reset angle of this waiting person in the specific information of this waiting person. Before the broadcast module broadcasts the name of this waiting person, the broadcast module transmits the identity information of the waiting person to be broadcast to the fourth extraction module. Then, the fourth extraction module extracts the first rotation angle or reset angle of this waiting person from the storage module and transmits it to the execution module, so that the controller works, and the display screen body rotates according to the first rotation angle or reset angle, so that the display screen body faces this waiting person, increasing the probability of attracting the attention of the waiting person and increasing the probability of the waiting person viewing the display screen body. Thus, in cooperation with the voice broadcast, the waiting person knows that he is being called, reducing the probability of the waiting person ignoring the call number and improving the convenience of the display screen.

[0028] 5. In the present invention, due to the large area of the display screen body, it has a large inertia. When the display screen body suddenly rotates, the display screen body will remain stationary under the action of inertia, thereby increasing the impact on the display screen body. Since there are a large number of electronic components inside the display screen body and the display screen body rotates frequently, the probability of damage to the display screen body increases. By setting the connecting member, the display screen body starts to rotate slowly or stops rotating slowly, thereby reducing the impact on the display screen body, reducing the probability of damage to the display screen body, and improving the reliability of the display screen body; because there are many people in public places, when a waiting person touches the display screen body, the display screen body will rotate, thereby reducing the impact between the display screen body and the waiting person, reducing the pain of the waiting person, and at the same time reducing the probability of damage to the display screen body.

Specific embodiments

[0041] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0042] As Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 10 shown, an intelligent LED electronic information display screen includes a display screen body 1, a connecting frame 2, a rotating component 3 and a controller 4; one end of the connecting frame 2 is connected to a wall; the other end of the connecting frame 2 is provided with the display screen body 1; the display screen body 1 is used to display waiting information; the display screen body 1 is rotatably connected to the connecting frame 2; the rotating component 3 is provided on the connecting frame 2; the rotating component 3 is connected to the connecting frame 2; the rotating component 3 is used to realize the rotation of the display screen body 1; the controller 4 is provided on the connecting frame 2; the controller 4 is fixedly connected to the connecting frame 2; the rotating component 3 is in electrical signal communication with the controller 4; the controller 4 is internally provided with a face recognition module, a position acquisition module, a first calculation module, an execution module, a reset module, a second calculation module, a timing module and a display module; the face recognition module is used to capture the facial contour of a waiting person gazing at the display screen body 1; the position acquisition module is used to acquire the position information of a waiting person gazing at the display screen body 1; the first calculation module is used to calculate a first rotation angle required for the display screen body 1 to rotate from the initial position to face the waiting person; the execution module is used to control the rotating component 3 to make the display screen body 1 rotate according to the first rotation angle; the reset module is used to make the display screen body 1 return to the initial position; the timing module is used to record the duration after the display screen body 1 rotates to face the waiting person; the second calculation module is used to calculate a reset angle required for the display screen body 1 to directly return to the initial position from the current position; the display module is used to display the waiting information of the waiting person.

[0043] During operation, the display module projects the waiting information of all waiters onto the display screen body 1. The face recognition module scans the facial contours of the waiters in the area in front of the display screen body 1. When a waiter wants to view the waiting information on the display screen body 1 and gazes at the display screen body 1 (the gazing time exceeds 3S), the face recognition module reaches the conclusion that the waiter at this place (denoted as the first waiter) needs to view the waiting information on the display screen body 1, thereby generating a position acquisition signal and transmitting it to the position acquisition module. After receiving the signal, the position acquisition module obtains the position information of the first waiter and transmits it to the first calculation module. Then, the first calculation module calculates the position information of the first waiter using a mathematical formula, thereby obtaining the first rotation angle required for the display screen body 1 to rotate from the current position (the initial position when it is the first waiter, that is, the display screen body 1 is parallel to the row of seats) to face the first waiter, and transmits the first rotation angle to the execution module. After receiving the first rotation angle information, the execution module controls the rotation component 3 to work, and then makes the display screen body 1 rotate towards the first waiter according to the first rotation angle through the rotation component 3, so that the display screen body 1 faces the first waiter, which is convenient for the first waiter to clearly see the waiting information on the display screen body 1, thereby improving the convenience of the display screen body 1; after the execution module makes the display screen body 1 rotate to face the first waiter, it generates a timing signal and transmits it to the timing module. Then, the timing module records the duration of the display screen body 1 facing the first waiter. When the duration is greater than the set time (set according to the time for the waiter to obtain information), the timing module stops timing and reaches the conclusion that the first waiter has finished obtaining information, and at the same time generates a reset signal and transmits it to the reset module. After receiving the reset signal, the reset module makes the rotation component 3 work, and then makes the display screen body 1 rotate in the reverse direction according to the first rotation angle, so that the display screen body 1 returns to the initial position;When the face recognition module recognizes again that the next waiting person (denoted as the second waiting person) is looking at the display body 1, and the duration recorded by the timing module is greater than the set time, the controller 4 continues to work in the above manner. When the duration recorded by the timing module is less than the set time, the position acquisition module acquires the position information of the second waiting person and transmits it to the first calculation module. Then, the first calculation module uses a mathematical formula to calculate the position information of the second waiting person, so as to obtain the second rotation angle required for the display body 1 to rotate from the current position to face the second waiting person, and transmits the second rotation angle to the execution module. At the same time, the timing module continues to time. When the duration is greater than the set time, the timing module stops timing and concludes that the first waiting person has finished obtaining information. At the same time, a signal for rotation again is generated and transmitted to the execution module. When the execution module receives the second rotation angle information and the signal for rotation again, it controls the rotating member 3 to work. Then, through the rotating member 3, the display body 1 rotates towards the second waiting person according to the second rotation angle, so that the display body 1 faces the second waiting person (after multiple waiting persons view the information of the display body 1 one after another, the above process is repeated). Thus, it is convenient for the second waiting person to view the waiting information, and it is avoided that after a waiting person finishes obtaining information and the display body 1 returns to the initial position, it then rotates to face the next waiting person for them to obtain information, thereby reducing the waiting time of the next waiting person and improving the convenience of the display body 1; after the execution module rotates the display body 1 to face the second waiting person, it generates a timing signal and transmits the timing signal to the timing module. Then, the timing module records the duration when the display body 1 faces the second waiting person. When the duration is greater than the set time, the timing module stops timing and concludes that the second waiting person has finished obtaining information. At the same time, a reset signal is generated and transmitted to the reset module and the second calculation module. After receiving the reset signal, the second calculation module calculates the first rotation angle and the second rotation angle, so as to calculate the reset angle required for the display body 1 to rotate from facing the second waiting person to the initial position, and transmits it to the reset module. After receiving the reset signal and the reset angle, the reset module makes the rotating member 3 work, so that the display body 1 rotates according to the reset angle, so that the display body 1 returns to the initial position, thus avoiding that the display body 1 needs to be reset multiple times to return to the initial position and facilitating the reset of the display body 1; when two or more waiting persons are looking at the display body 1 at the same time, the face recognition module generates extraction signals successively according to the distance of the waiting persons from the display body 1, so that the display body 1 faces the waiting persons in turn according to the distance, thus avoiding the waiting persons staring at the display body 1 for a long time, reducing the probability of eye discomfort of the waiting persons, and at the same time avoiding the waiting persons walking to the front of the display body 1 to view, thus facilitating the waiting persons to clearly see the display body 1 in place and improving the convenience of the display.

[0044] Such asFigure 3 and Figure 8 As shown in Figure 8 , the controller 4 is further provided with an information input module, a storage module, a download module, a database module, a simplification module and an upload module; the face recognition module is provided with a face scanning unit; the face scanning unit is used for scanning the facial image of the waiting person; the information input module is used for inputting the identity information and matters to be handled of the waiting person; the database module is used for storing the precautions and related materials corresponding to specific matters; the download module is used for downloading the corresponding precautions and related materials from the database module according to the matters to be handled by the waiting person; the storage module is used for recording the identity information, facial image, matters to be handled and precautions of the waiting person; the upload module is used for transmitting the information of the waiting person to the window staff; the simplification module is used for refining and simplifying the information of the waiting person.

[0045] When the waiting person conducts information registration, the waiting person inputs his / her identity information and matters to be handled according to the requirements of the information input module. Subsequently, the information input module transmits the identity information and matters to be handled of the waiting person to the storage module. At the same time, the information input module generates a download signal and transmits it to the face recognition module and the download module. After receiving the download signal, the face recognition module makes the face scanning unit work. Then, the face scanning unit scans the face of the waiting person, and then forms a facial image and transmits it to the storage module. After receiving the download signal, the download module extracts the corresponding precautions (such as various materials required for handling social security business, how to protect oneself according to the condition when seeing a doctor, and taboos of the condition, etc.) from the database module according to the matters to be handled by the waiting person, and transmits them to the storage module. The storage module stores the information of the waiting person, namely the facial image, identity information, matters to be handled and precautions. Subsequently, the upload module transmits the materials of the waiting person to the corresponding window staff, which is convenient for the window staff to make an overall plan for the subsequent work, optimize the work process, improve the work efficiency, and shorten the waiting time of the waiting person; at the same time, the simplification module refines the materials of the waiting person and transmits them to the display module for display on the display screen body 1. By simplifying the materials of the waiting person through the simplification module, the amount of materials to be displayed is reduced, the screen size occupied by the materials is reduced, the number of waiting persons that the display screen body 1 can display is increased, and more waiting persons can view the waiting information.

[0046] such as Figure 3 and Figure 8As shown, the controller 4 further includes a gesture recognition module, a first extraction module, a second extraction module, a first comparison module, a transmission module, and a cache module. The gesture recognition module is used to recognize the gestures of the waiters. The first extraction module is used to extract the facial images of the waiters from the face scanning unit. The cache module is used to temporarily store the information of the waiters. The first comparison module is used to compare the facial images of the waiters with the facial images in the storage module. The second extraction module is used to extract the specific information of the waiters from the cache module. The transmission module is used to transmit the specific information of the waiters to the display module.

[0047] When the display screen body 1 faces the waiter directly, the waiter makes a gesture to view the detailed waiting information with his hand. Thus, the gesture recognition module recognizes the gesture of the waiter, draws the conclusion that the waiter needs to view the detailed waiting information, generates an extraction signal and transmits it to the first extraction module. The first extraction module receives the signal, extracts the facial image of the waiter from the face scanning unit, and transmits the facial image of the waiter to the first comparison module. Then, the first comparison module compares the facial image with the facial images in the storage module one by one. When the facial image of a certain waiter matches this facial image, the first comparison module stops the comparison, generates a transmission signal, and transmits the transmission signal to the transmission module. After receiving the transmission signal, the transmission module transmits the specific information of this waiter in the storage module to the display module. Then, the specific information of this waiter is displayed on the display screen body 1, which is convenient for the waiter to view the precautions for the matters he handles, convenient for the user to make preparations in advance, and improves the convenience of the display screen. At the same time, the transmission module transmits the information of this waiter to the cache module. When the face scanning unit scans the facial image of this waiter again, the face scanning unit generates a signal for re-extraction and transmits the re-extraction signal to the second extraction module. Then, the second extraction module extracts the specific information of this waiter from the cache module and transmits it to the display module, which is convenient for the waiter to view his own information on the display screen body 1 again, saves the waiting time of the waiter, and improves the convenience of the display screen.

[0048] As Figure 3 and Figure 8 As shown, the controller 4 further includes a third extraction module, a fourth extraction module, a second comparison module, and a broadcast module. The third extraction module is used to extract the facial images of the waiters from the face scanning unit. The second comparison module is used to compare the facial images of the waiters with the facial images in the storage module. The fourth extraction module is used to extract the first rotation angle or the reset angle of the waiter from the storage module. The broadcast module is used to broadcast the name of the waiter.

[0049] After receiving the reset signal, the reset module transfers the corresponding first rotation angle or reset angle of the waiters to the storage module. Meanwhile, the reset module generates a storage extraction signal and transfers it to the third extraction module. The third extraction module extracts the facial image of the waiter from the face scanning unit after receiving the signal, and transfers the facial image of the waiter to the second comparison module. Then, the second comparison module compares the facial image with the facial images in the storage module one by one. When the facial image of a certain waiter matches this facial image, the second comparison module stops the comparison and generates a storage signal, and transfers the storage signal to the storage module. Then, the storage module stores the first rotation angle or reset angle of the waiter into the specific information of the waiter. Before the broadcast module announces the name of the waiter, the broadcast module transfers the identity information of the waiter to be announced to the fourth extraction module. Then, the fourth extraction module extracts the first rotation angle or reset angle of the waiter from the storage module and transfers it to the execution module, which causes the controller 4 to work, and then causes the display body 1 to rotate according to the first rotation angle or reset angle, so that the display body 1 faces the waiter directly, thereby increasing the probability of attracting the attention of the waiter, and then increasing the probability of the waiter viewing the display body 1. Thus, in cooperation with the voice broadcast, the waiter knows that he is being called, thereby reducing the probability of the waiter ignoring the call number and improving the convenience of the display screen.

[0050] As Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10 shown, the rotating member 3 includes a connecting shaft 31, a driving shaft 32, a connecting member 33 and a first motor 34; the upper and lower ends of the connecting frame 2 are symmetrically provided with the connecting shafts 31; the connecting shaft 31 is rotatably connected to the connecting frame 2; one of the connecting shafts 31 is fixedly connected to the upper end of the display body 1; the other connecting shaft 31 is fixedly connected to the lower end of the display body 1; the driving shaft 32 is provided on the connecting frame 2; the driving shaft 32 is rotatably connected to the connecting frame 2; the connecting shaft 31 and the driving shaft 32 are connected by the connecting member 33; the connecting member 33 is made of a flexible shell torsion material; one end of the connecting member 33 is connected to the connecting shaft 31; the other end of the connecting member 33 is connected to the driving shaft 32; the first motor 34 is fixedly connected to the connecting frame 2; the rotating shaft of the first motor 34 is connected to the driving shaft 32 through a first transmission assembly 35; the first motor 34 is electrically connected to the controller 4.

[0051] Since the display screen body 1 has a large area and thus has a large inertia, when the display screen body 1 suddenly rotates, the display screen body 1 will remain stationary under the action of inertia (when the display screen body 1 suddenly stops rotating, the display screen body 1 will continue to rotate under the action of inertia), thereby increasing the impact on the display screen body 1. Since there are a large number of electronic components inside the display screen body 1 and the display screen body 1 rotates frequently, the probability of damage to the display screen body 1 is increased. By providing a connecting member 33 (a part such as a spring that can twist and transmit torque), the display screen body 1 starts to rotate slowly or stops rotating slowly, thereby reducing the impact on the display screen body 1, reducing the probability of damage to the display screen body 1, and improving the reliability of the display screen body 1. Since there are many people in public places, when a waiting person touches the display screen body 1, the display screen body 1 will rotate, thereby reducing the impact between the display screen body 1 and the waiting person, reducing the pain of the waiting person, and at the same time reducing the probability of damage to the display screen body 1.

[0052] As Figure 3 , Figure 4 , Figure 8 and Figure 9 shown, a fan 5 is provided on one side of the display screen body 1 close to the connecting frame 2; the fans 5 are evenly spaced up and down; the rotating shaft of the fan 5 is horizontally arranged; the rotation of the fan 5 is parallel to the side surface of the display screen body 1; the rotating shafts of all the fans 5 rotate synchronously; a second gear 61 is provided on the connecting frame 2; the second gear 61 is fixedly connected to the connecting frame 2; a mounting seat 62 is provided on the display screen body 1; the mounting seat 62 is fixedly connected to the display screen body 1; a first rotating shaft 63 is provided on the mounting seat 62; the first rotating shaft 63 is rotatably connected to the mounting seat 62; a first gear 64 is provided at one end of the first rotating shaft 63; the first gear 64 is fixedly connected to the first rotating shaft 63; the first gear 64 meshes with the second gear 61; a first bevel gear 65 is provided at the other end of the first rotating shaft 63; the first bevel gear 65 is fixedly connected to the first rotating shaft 63; a second rotating shaft 66 is provided on the mounting seat 62; the second rotating shaft 66 is rotatably connected to the mounting seat 62; a second bevel gear 67 is provided on the second rotating shaft 66; the second bevel gear 67 is fixedly connected to the second rotating shaft 66; the second bevel gear 67 meshes with the first bevel gear 65; the rotating shaft of the fan 5 close to the second rotating shaft 66 is connected to the second rotating shaft 66 through a second transmission component 68.

[0053] Due to the large area of the display screen body 1, when one side of the display screen body 1 approaches the wall, the air on the back of this side is squeezed, thereby increasing the air pressure received on the back of this side. At the same time, the air pressure on the front of this side decreases, thereby causing a resistance force in the direction away from the wall on this side of the display screen body 1. At the same time, the other side moves away from the wall. As a result, the air pressure on the face of this side increases and the air pressure on the back decreases. As a result, a resistance force in the direction towards the wall is exerted on this side of the display screen body 1. As a result, both sides of the display screen body 1 are subjected to air resistance, thereby hindering the rotation of the display screen body 1. When the display screen body 1 rotates, the display screen body 1 drives the first gear 64 to move. Also, because the first gear 64 meshes with the second gear 61, it drives the first gear 64 to rotate around its own axis, thereby driving the first rotating shaft 63 to rotate, thereby driving the first bevel gear 65 to rotate, thereby driving the second bevel gear 67 to rotate, thereby driving the second rotating shaft 66 to rotate, and then driving the rotating shaft of a fan 5 to rotate through the second transmission assembly 68, thereby driving the rotating shafts of all the fans 5 to rotate, thereby driving all the fans 5 to rotate, thereby generating a suction force on the air on the back of the display screen body 1, thereby causing the air on the back of the side approaching the wall to move to the other side, thereby reducing the air pressure on the back of the side approaching the wall, thereby reducing the pressure difference between the back and the face of the side approaching the wall, thereby reducing the resistance of this side of the display screen body 1 to approach the wall, and at the same time increasing the air pressure on the back of the side away from the wall, thereby reducing the pressure difference between the face and the back of the side away from the wall, thereby reducing the resistance of this side of the display screen body 1 to move away from the wall, thereby reducing the resistance received when the display screen body 1 rotates, thereby realizing the reliable rotation of the display screen body 1, and thereby improving the reliability of the display screen during operation.

[0054] As Figures 3 to 10 shown, a baffle 69 is provided on the side of the display screen body 1 close to the connecting frame 2; the baffles 69 are evenly spaced up and down; the baffle 69 is fixedly connected to the display screen body 1; the fans 5 are arranged between two adjacent baffles 69.

[0055] By providing the baffle 69, the air is guided, thereby increasing the stability of the air flow, effectively reducing the resistance received when the display screen body 1 rotates, thereby realizing the reliable rotation of the display screen body 1, and thereby improving the reliability of the display screen during operation.

[0056] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 10As shown, three cameras 71 are provided on the display screen body 1; the cameras 71 are connected to the face recognition module; one of the cameras 71 is arranged directly below the display screen body 1; the other two cameras 71 are respectively arranged on the left and right sides of the display screen body 1; a second synchronous pulley 72 is provided on the connecting frame 2; the second synchronous pulleys 72 are arranged at intervals; the two second synchronous pulleys 72 are fixedly connected; one of the second synchronous pulleys 72 is fixedly connected to the connecting frame 2; third rotating shafts 73 are provided on both sides of the display screen body 1; the third rotating shafts 73 are rotatably connected to the display screen body 1; third synchronous pulleys 74 are provided on the third rotating shafts 73; the third synchronous pulleys 74 are fixedly connected to the third rotating shafts 73; a first synchronous belt 75 is connected between the second synchronous pulley 72 and the third synchronous pulley 74; the cameras 71 are arranged on the third rotating shafts 73; the cameras 71 are fixedly connected to the third rotating shafts 73; the working surface diameters of the first synchronous belt 75 pulley and the second synchronous pulley 72 are equal.

[0057] When the display screen body 1 rotates too much to one side, the camera 71 on the other side cannot scan the facial image of the waiting person. At this time, the display screen body 1 needs to return to the initial position, or the facial image of the waiting person can be recognized only during the process of returning to the initial position, thereby increasing the waiting time of the waiting person. By arranging the cameras 71 at both ends of the display screen body 1, when the display screen body 1 rotates a certain angle to one side, the display screen body 1 drives the first synchronous belt 75 to rotate around the axis of the drive shaft 32. Also, because the second synchronous pulley 72 does not move, the first synchronous belt 75 is moved a certain distance, thereby driving the third synchronous pulley 74 to rotate in the reverse direction by a certain angle, and then driving the camera 71 to rotate in the reverse direction by a certain angle, so that the camera 71 is always directly opposite the left and right sides of the initial position of the display screen body 1, facilitating the camera 71 to capture the facial image of the waiting person on the side, reducing the waiting time of the waiting person on the side, and improving the convenience of the display screen.

[0058] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 10 shown, the camera 71 is a wide-angle lens.

[0059] By setting the wide-angle lens, the camera 71 can capture the facial image of the waiting person in the distance, so that the display screen body 1 rotates to the angle directly opposite the waiting person in the distance, facilitating the waiting person in the distance to view the waiting information and improving the applicability of the display screen.

[0060] During operation, the display module projects the waiting information of all waiters onto the display screen body 1. The face recognition module scans the facial contours of the waiters in the area in front of the display screen body 1. When a waiter wants to view the waiting information on the display screen body 1 and gazes at the display screen body 1 (the gazing time exceeds 3S), the face recognition module reaches the conclusion that the waiter at this location (denoted as the first waiter) needs to view the waiting information on the display screen body 1, thereby generating a position acquisition signal and transmitting it to the position acquisition module. After receiving the signal, the position acquisition module obtains the position information of the first waiter and transmits it to the first calculation module. Then, the first calculation module uses a mathematical formula to calculate the position information of the first waiter, thereby obtaining the first rotation angle required for the display screen body 1 to rotate from the current position (the initial position when it is the first waiter, that is, the display screen body 1 is parallel to the row of seats) to face the first waiter, and transmits the first rotation angle to the execution module. After receiving the first rotation angle information, the execution module controls the rotation component 3 to work, and then rotates the display screen body 1 towards the first waiter according to the first rotation angle through the rotation component 3, so that the display screen body 1 faces the first waiter, which is convenient for the first waiter to clearly see the waiting information on the display screen body 1, thereby improving the convenience of the display screen body 1; after the execution module rotates the display screen body 1 to face the first waiter, it generates a timing signal and transmits it to the timing module. Then, the timing module records the duration of the display screen body 1 facing the first waiter. When the duration is greater than the set time (set according to the time for the waiter to obtain information), the timing module stops timing and reaches the conclusion that the first waiter has finished obtaining information. At the same time, it generates a reset signal and transmits it to the reset module. After receiving the reset signal, the reset module makes the rotation component 3 work, and then rotates the display screen body 1 in the reverse direction according to the first rotation angle, so that the display screen body 1 returns to the initial position;When the face recognition module recognizes again that the next waiting person (denoted as the second waiting person) is looking at the display body 1, and the duration recorded by the timing module is greater than the set time, the controller 4 continues to work in the above manner. When the duration recorded by the timing module is less than the set time, the position acquisition module acquires the position information of the second waiting person and transmits it to the first calculation module. Then, the first calculation module uses a mathematical formula to calculate the position information of the second waiting person, so as to obtain the second rotation angle required for the display body 1 to rotate from the current position to face the second waiting person, and transmits the second rotation angle to the execution module. At the same time, the timing module continues to count. When the duration is greater than the set time, the timing module stops counting and concludes that the first waiting person has finished obtaining information. At the same time, a signal for rotation again is generated and transmitted to the execution module. When the execution module receives the second rotation angle information and the signal for rotation again, it controls the rotation component 3 to work. Then, through the rotation component 3, the display body 1 rotates towards the second waiting person according to the second rotation angle, so that the display body 1 faces the second waiting person (after multiple waiting persons successively view the information of the display body 1, the above process is repeated). Thus, it is convenient for the second waiting person to view the waiting information, and it is avoided that after a waiting person finishes obtaining information and the display body 1 returns to the initial position, it then rotates to face the next waiting person for them to obtain information, thereby reducing the waiting time of the next waiting person and improving the convenience of the display body 1; after the execution module rotates the display body 1 to face the second waiting person, it generates a timing signal and transmits the timing signal to the timing module. Then, the timing module records the duration during which the display body 1 faces the second waiting person. When the duration is greater than the set time, the timing module stops counting and concludes that the second waiting person has finished obtaining information. At the same time, a reset signal is generated and transmitted to the reset module and the second calculation module. After receiving the reset signal, the second calculation module calculates the first rotation angle and the second rotation angle, so as to calculate the reset angle required for the display body 1 to rotate from facing the second waiting person to the initial position, and transmits it to the reset module. After receiving the reset signal and the reset angle, the reset module makes the rotation component 3 work, so that the display body 1 rotates according to the reset angle, so that the display body 1 returns to the initial position, thus avoiding that the display body 1 needs to be reset multiple times to return to the initial position and facilitating the reset of the display body 1; when two or more waiting persons are looking at the display body 1 at the same time, the face recognition module successively generates extraction signals according to the distance of the waiting persons from the display body 1, so that the display body 1 faces the waiting persons in turn according to the distance, thus avoiding the waiting persons staring at the display body 1 for a long time, reducing the probability of eye discomfort of the waiting persons, and at the same time avoiding the waiting persons walking to the front of the display body 1 to view, thus facilitating the waiting persons to clearly see the display body 1 in place and improving the convenience of the display.
