[0034] Electronic class cards are one of the systems for campus culture construction and digital construction today. They are a good application carrier for realizing smart campuses in daily school work, class culture display, and classroom communication. Each class is equipped with one card installed at the door of the classroom, which greatly enriches the overall information technology environment of the school, realizes the perfect integration of daily school work and environmental beautification, and provides a high-quality carrier for all-round cultivation and creation of campus cultural environment.

[0035] In the related art, electronic class signs are usually installed at the door of the classroom, which can be easily damaged due to long-term direct sunlight, and the electronic class signs can only be repaired through inspections or passive processing. In this way, the maintenance cost of the electronic class signs is high, and maintenance personnel cannot detect damaged electronic class signs in time and respond quickly.

[0036] To solve the above problems, please refer to Figures 1 to 3 The present application proposes an electronic class sign system 1. In an embodiment of the present application, the electronic class sign system 1 includes an electronic class sign 10 and an information processing module.

[0037] In some embodiments, the electronic class sign 10 includes a housing 11, a screen 12 installed on the housing 11, a camera module 15 and a light sensor 16, and the screen 12, the camera module 15 and the light sensor 16 are all electrically connected to the information processor.

[0038] The information processing module is used to communicate with the external network, receive information sent by the camera module 15 and the light sensor 16, and issue an excessive light warning prompt. The information processing module includes a processor 13, a communication module 14, and a background processor. The screen 12, the communication module 14, the camera module 15, and the light sensor 16 are all electrically connected to the processor 13.

[0039] The communication module 14 is used to communicate with the external network, and includes at least one of a WiFi communication unit, a Bluetooth communication unit and a wired communication unit. It can connect to the WiFi and / or Bluetooth module through a proprietary interface to achieve wireless and Bluetooth connection. At the same time, it also supports wired network transmission when the wireless network signal is poor, such as through optical cable transmission.

[0040] Specifically, the communication module 14 can search and collect the surrounding wireless AP signals through the WiFi communication unit, thereby obtaining the MAC address broadcast by the AP signal, and sending these data that can mark the AP signal to the positioning server. The positioning server retrieves the geographical location of each AP signal, and combines the strength of each signal to calculate the geographical location of the electronic class sign 10 and transmit it back to the communication module 14. The communication module 14 obtains the local sunshine intensity and weather forecast information of the day through the Internet based on the geographical location of the class sign installation obtained above, and sends it to the processor 13.

[0041] The camera module 15 is used to shoot the external environment of the electronic class sign 10, and intuitively present the setting environment of the electronic class sign 10 and the degree of direct sunlight exposure during multiple time periods of the day in the form of pictures and / or videos, and send them to the processor 13.

[0042] The light sensor 16 can collect the light intensity of the external environment in real time, which is used to detect the light intensity of the external environment of the electronic class sign 10, and send the collected real-time light intensity of the external environment to the processor 13. The real-time light intensity of the external environment is collected multiple times by the light sensor 16, so that the power consumption is low and the data accuracy will also be improved.

[0043] The processor 13 is provided with interfaces such as UART interface / I2C interface / SPI interface, LVDS interface, USB interface, SDIO interface, etc., which are used to be electrically connected to the screen 12, communication module 14, camera module 15 and light sensor 16, and receive information sent by the communication module 14, camera module 15 and light sensor 16, and transmit it to the background server.

[0044] The background server is used to receive the data uploaded by the processor 13, and determine the accurate sunlight intensity received by the electronic class sign 10 in combination with the positioning information and sunlight intensity transmitted by the communication module 14 and the camera module 15, assisted by the real-time light intensity collected by the light sensor 16, and analyze and judge the above data in the form of manual or AI. If it is determined that the sunlight intensity received by the electronic class sign 10 is greater than a preset threshold, the background server will issue an excessive light warning prompt, and send the warning signal to the preset maintenance person in charge, so that the maintenance person in charge can maintain the electronic class sign 10 in time, take protective measures in time, such as adding curtains, etc., and repair and replace the electronic class sign 10 that has a certain degree of damage in time. In this way, the maintenance efficiency of the electronic class sign 10 is greatly improved, and the damage probability of the electronic class sign 10 is effectively reduced. At the same time, there is no need to use patrol inspections or passive processing to report the electronic class sign 10, thereby reducing maintenance costs.

[0045] In some embodiments, the screen 12 is a touch screen, and its implementation form is exemplary, the screen 12 includes a display module and an infrared touch frame, the infrared touch frame is surrounded by the display module and electrically connected to the display module, and the infrared touch frame is provided with a plurality of transmitting units and a plurality of receiving units, and each transmitting unit cooperates with the corresponding receiving unit to work. The infrared touch frame is electrically connected to the processor 13. When the user touches the display module, each transmitting unit and each receiving unit of the infrared touch frame perform infrared sensing on the user's operation, generate a corresponding touch signal according to the corresponding data, and send the generated touch signal to the processor 13. The processor 13 converts the touch signal into a picture signal and displays it through the display module, thereby realizing the human-computer interaction function of the electronic class sign 10. Of course, the screen 12 can also be implemented in other forms as a touch screen, for example, the screen 12 is set to a capacitive screen, an electromagnetic screen, etc., and this application does not limit this.

[0046] In addition, the processor 13 can also automatically adjust the brightness of the screen 12 according to the real-time received external environment brightness. When the external environment brightness is dark, the processor 13 can send a signal to increase the brightness of the screen 12; when the external environment brightness is bright, the processor 13 can also send a signal to lower the brightness of the screen 12, so that students and teachers can more conveniently use the screen 12 for touch operations.

[0047] Please refer to Figures 2 to 4 In some embodiments, the housing 11 includes a front panel 111, a frame 112, and a rear housing 113. The front panel 111, the frame 112, and the rear housing 113 enclose a mounting cavity 114. The processor 13, the communication module 14, the camera module 15, and the light sensor 16 are all disposed in the mounting cavity 114. The screen 12 is exposed by the front panel 111. The connection between the front panel 111, the frame 112, and the rear housing 113 may be a detachable connection such as a screw connection, a snap connection, etc., or a fixed connection such as welding, bonding, etc., which is not limited in the present application.

[0048] Among them, the front panel 111 has a light-transmitting area 1111, and the light-transmitting area 1111 corresponds to the position of the light sensor 16. The light-transmitting area 1111 is an open hole structure, which is simple to shape and has low cost, and is convenient for light to be directly transmitted from the opening into the installation cavity 114 for reception by the light sensor 16. In addition, the light-transmitting area 1111 can also be made of other materials and arranged on the front panel 111, and be an integrally formed structure with the front panel 111, or can be installed on the front panel 111 in a detachable form, and the detachable form includes but is not limited to screw connection, snap connection, etc. The surface shape of the light-transmitting area 1111 can be selected as a spherical shape, and a concave lens is provided on the inner surface and / or the outer surface to refract light, increase the photosensitivity range of the light sensor 16, and improve the photosensitivity effect of the light sensor 16. In this way, the ambient light intensity sensed by the light sensor 16 can be further made more accurate. It is understandable that the shape of the light-transmitting area 1111 is not limited to a sphere. In other embodiments, it can also be set to other shapes as needed, such as a rectangle, an ellipse, etc., and the present application does not impose any limitation on this.

[0049] Optionally, the frame 112 is made of metal, such as aluminum alloy, stainless steel, etc., which has a high material strength to protect the electronic devices in the installation cavity 114, and at the same time has a large supporting strength for the electronic class sign 10 as a whole. Because the frame 112 is set to be made of metal, it will cause certain signal interference to the communication module 14, and will block the light sensor 16, reducing its light sensitivity, and it is not convenient for the camera of the camera module 15 to open the hole for shooting. Therefore, the communication module 14, the camera module 15, and the light sensor 16 are all located below the screen 12 and along the length direction of the front panel 111 (such as Figure 2 The front panel 111 is arranged in a spaced manner along the length direction X) as shown, which saves space in the installation cavity 114, and the arrangement is simple and does not interfere with each other. At the same time, the communication module 14, the camera module 15, and the light sensor 16 are arranged along the length direction X of the front panel 111, which can avoid the metal frame 112, so as to avoid the frame 112 affecting the normal operation of the communication module 14, the camera module 15 and the light sensor 16. Therefore, the front panel 111 can be made of plastic material, such as polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP) and ABS resin, etc., which can avoid signal interference to the communication module 14, the light sensor 16 and other devices in the installation cavity 114, and the molding is simple and the cost is low.

[0050] In addition, if Figure 2As shown in the example, the camera module 15 is located in the middle of the front panel 111 along the length direction X, and is located between the communication module 14 and the light sensor 16, that is, the camera module 15 can be selectively set on the central axis of the electronic class sign 10, so that it is more convenient for the camera module 15 to capture the full picture of the position of the electronic class sign 10. Of course, the camera module 15 can also be located at any position of the front panel 111 along the length direction X. For example, the camera module 15 is set adjacent to the side of the front panel 111, so that the side position of the installation position of the electronic class sign 10 can be photographed, and this application does not limit this.

[0051] Please refer to Figure 4 The electronic class board system 1 also includes a data interface 18, which is electrically connected to the processor 13. The data interface 18 is used to electrically connect the electronic class board 10 with other devices, or to transmit and store data between a removable storage device (such as a USB flash drive, a mobile hard disk, etc.) and the electronic class board 10. The electronic class board 10 is usually hung on the wall at the entrance of the classroom, and the distance between its rear shell 113 and the wall is small or close to the wall. For the overall neatness and aesthetics of the electronic class board 10, its wiring method is usually to arrange the wires at the rear shell 113. Therefore, the rear shell 113 is recessed to form a wire management groove 1131, and the data interface 18 is exposed by the side wall of the wire management groove 1131. This can facilitate the wiring design of the electronic class board 10, make it simple and beautiful, and occupy less space for wiring, thereby reducing the occupied space of the electronic class board 10. Optionally, the data interface 18 may be disposed at other locations of the electronic sign 10 , such as on the frame 112 , and the location of the data interface 18 will not obstruct the location of the communication module 14 , the camera module 15 and the light sensor 16 .

[0052] Please refer again Figure 2 In some embodiments, the electronic class sign system 1 further includes a speaker module 17, which is disposed in the housing 11 and electrically connected to the processor 13. The electronic class sign 10 can play audio through the speaker module 17, such as playing notifications and announcements. A sound outlet 115 is also provided at a position of the housing 11 relative to the speaker module 17, so that the audio played by the speaker module 17 can be transmitted outward through the sound outlet 115.

[0053] It is understandable that the speaker module 17 can also be located below the screen 12 and can be located at any position on the front panel 111. Since the front panel 111 is made of plastic, the audio weakening effect of the speaker module 17 during playback can be reduced. That is, the speaker module 17 can be arranged with the communication module 14, the camera module 15 and the light sensor 16 along the length direction X of the front panel 111; it can also be arranged with the communication module 14, the camera module 15 and the light sensor 16 along the height direction of the front panel 111 (such as Figure 2 Furthermore, the speaker module 17 can also be selected with the communication module 14, the camera module 15 and the light sensor 16 in the thickness direction of the electronic class card 10 (such as Figure 2 To accommodate the position of the speaker module 17, the sound outlet 115 can be provided at any position on the front panel 111, the frame 112, and the rear shell 113. For example, the sound outlet 115 can be provided at the bottom or side of the frame 112, etc., and the present application does not limit this.

[0054] In some embodiments, the electronic class sign system 1 also includes an infrared module. The processor 13 can connect to the infrared remote control through the infrared module and receive the control signal of the infrared remote control. The user can use the remote control to operate the electronic class sign 10 to achieve wireless control, making human-computer interaction more convenient and quick.

[0055] In addition, the electronic class sign system 1 also includes a power module, which is arranged in the casing 11. The power module provides power for the operation of the electronic class sign 10. It can be a rechargeable battery and can be optionally a lithium-ion battery to ensure that it can be used as a backup power supply to power the electronic class sign 10 in the event of a sudden power outage.
