[0024] Reference Figure 1-4 The figure shows a preferred embodiment of the present invention.

[0025] The multi-screen linkage guidance system provided in this embodiment can be used in any occasion, such as outdoors, in underground parking lots, etc., and is not limited to a specific occasion.

[0026] The multi-screen linked guidance system includes a plurality of guidance screens 100 arranged at intervals along the guidance route and a controller. The plurality of guidance screens 100 communicate with the controller respectively, and the controller controls the plurality of guidance screens 100 to display synchronized video content. The controller serves as a control system, and can control the video content of the plurality of guidance screens 100, and control the plurality of guidance screens 100 to play videos with the same content.

[0027] The guide screen 100 is provided with a camera 102, which forms an image detection area 101 in front of the guide screen 100. As long as a person enters the image detection area 101, he or she can be detected by the camera 102. There is an interval blind area between the image detection areas 101 of the cameras 102 on adjacent guide screens 100, and the interval blind area here refers to a position that the camera 102 cannot scan.

[0028] There is a spacing area 200 between adjacent guide screens 100, and an infrared sensor is provided in the middle of the spacing area 200. The infrared sensor is aligned with the spacing blind area. When a person walks out of the image detection area 101 and enters the image detection area 101 of the camera 102 on another guide screen 100, he needs to pass through the spacing area 200, so that the infrared sensor can detect and judge the direction of the person. The camera 102 on the guide screen 100 detects whether there is someone in the image detection area 101, and the controller controls the guide screen 100 to start or shut down. Specifically, when the camera 102 detects that there is someone in the image detection area 101, the controller controls the guide screen 100 to start and display the video content of the guide. When the person walks out of the current image detection area 101, the current guide screen 100 is shut down. When the person enters the next image detection area 101, the guide screen 100 corresponding to the next image detection area 101 is started.

[0029] The multi-screen linkage guide system provided above is provided with multiple guide screens 100, and the multiple guide screens 100 display synchronous video content. The camera 102 on the guide screen 100 determines whether there is a person in the image detection area 101, so that the controller starts the corresponding guide screen 100. In this way, as people walk in front of the multiple guide screens 100, the guide screens 100 are replaced and started in sequence, and the guidance range is wide. The guide screens 100 are started as people walk, which is energy-saving and environmentally friendly. The direction of people's walking can be determined by infrared sensors.

[0030] The guide screen 100 is provided with an ultrasonic head that emits ultrasonic waves. The ultrasonic head detects the distance data of the person in the image detection area 101 from the guide screen 100, and the controller controls the brightness of the guide screen 100 according to the distance data. The smaller the distance between the person and the guide screen 100, the smaller the brightness of the guide screen 100, which saves energy and protects the environment while ensuring that the person can clearly see the video content on the guide screen 100.

[0031] A recorder is provided on the guide screen 100, and the controller controls the video content played by the guide screen 100 according to the recording data of the recorder. The recorder can record or obtain human voice. According to the content of the voice, the controller can control the video content of the guide screen 100, or can also record in a specific time period, etc., or can keep the recording for a long time and store the recording content.

[0032] A SIM card slot is provided in the guide screen 100, a SIM card is inserted in the SIM card slot, and the SIM card is electrically connected to the controller, so that the guide screen 100 can realize multiple functions such as communication, call and network.

[0033] The infrared sensor has a horizontal infrared emitting port 301, which is flat and arranged horizontally along the spacing area 200 between adjacent guide screens 100. In this way, the infrared sensor emits infrared rays through the horizontal infrared emitting port 301, and the emitted infrared rays are gathered in a flat shape. In this way, the direction of the person can be determined based on the contact between the person and the infrared rays and the reflection of the infrared rays.

[0034] The middle part of the horizontal infrared emitting port 301 extends downward to form a longitudinal infrared emitting port 302 arranged longitudinally, so that the scanning range of the infrared ray can be increased to ensure that the position and direction of a person can be accurately scanned.

[0035] The guide screen 100 has a side wall facing the adjacent guide screen 100, and a recessed groove 103 is provided on the side wall. A laser projector 104 for projecting onto the spacing area 200 is provided in the recessed groove 103; when the camera 102 detects that a person directly in front of the guide screen 100 enters the spacing area 200, the laser projector 104 projects a guiding video onto the spacing area 200 according to the direction in which the person is walking.

[0036] In this way, in the interval area 200 between adjacent guide screens 100, walking guide images can also be projected as people walk.

[0037] A suction cup 300 is connected to the back of the guide screen 100, and a main suction cavity 301 is formed in the middle of the suction cup 300. A plurality of auxiliary suction cavities 302 that are connected to each other are formed on the periphery of the main suction cavity 301. The auxiliary suction cavities 302 are isolated from the main suction cavity 301, and the plurality of auxiliary suction cavities 302 are arranged at intervals around the periphery of the main suction cavity 301.

[0038] In this way, when the guide screen 100 needs to be installed, the main suction cavity 301 and the auxiliary suction cavity 302 of the suction cup 300 can be directly adsorbed on the wall, etc., and the main suction cavity 301 and the auxiliary suction cavity 302 are isolated from each other, and the auxiliary suction cavity 302 is arranged around the periphery of the main suction cavity 301, so that the adsorption is more stable.

[0039] The main suction chamber 301 is connected to a main suction pipe, and the auxiliary suction chamber 302 is connected to an auxiliary suction pipe, and the main suction pipe and the auxiliary suction pipe are respectively connected to a suction pump. In this way, when installing the guide screen 100, the main suction chamber 301 and the auxiliary suction chamber 302 can be directly evacuated using an external suction pump, so that the main suction chamber 301 and the auxiliary suction chamber 302 can be firmly adsorbed on a wall, etc., and the operation is simple and convenient.

[0040] A bracket is provided at the bottom of the guide screen 100, and a horizontally arranged support plate 400 is provided at the top of the bracket. A mounting plate for fixed installation is connected to the bottom of the support plate 400. By fixing the mounting plate on a wall, etc., and then using the support plate 400 to drag the guide screen 100 from bottom to top, the installation of the guide screen 100 is made more stable.

[0041] A transversely arranged groove strip 401 is provided on the top of the support plate 400, and a plurality of elastic pad strips 402 are provided in the groove strip 401, and the plurality of elastic pad strips 402 are arranged at intervals along the length direction of the groove strip 401; the bottom of the guide screen 100 is embedded in the groove strip 401 and abuts against the plurality of elastic pad strips 402, and the elastic pad strips 402 can buffer the downward pressure of the guide screen 100 and adjust the orientation of the guide screen 100.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
