[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] [Example 1]

[0042] The inventor of this solution found that in the prior art, electronic whiteboards are widely used in education, business and other fields as a modern teaching and demonstration tool. Existing electronic whiteboards usually do not automatically adjust the brightness and volume when no one is using them, which easily leads to energy waste. At the same time, when the sensor fails or the system restarts, the recovery of the system status often requires manual operation, which is not convenient enough. Embodiment 1 of the present invention provides the following solution:

[0043] like Figure 1 to Figure 2 As shown, this embodiment provides an electronic whiteboard adjustment method, the method comprising the following steps:

[0044] Step 101: The electronic whiteboard detects in real time whether a user exists. It should be noted that the user is a user who uses the electronic whiteboard.

[0045] Specifically, the electronic whiteboard may be a copy-type electronic whiteboard, an interactive electronic whiteboard, or an optical electronic whiteboard.

[0046] The copy-type electronic whiteboard can scan and print out the content written on the whiteboard in a certain way through simple operations of the user. Its function completion process is the same as the ordinary copy process. First, the image sensor collects the content on the whiteboard. After the collected signal undergoes certain image processing, it is finally output by thermal, inkjet or other printing methods. The printing output methods generally include thermal paper output and inkjet ordinary paper output, and the colors are black and white and color output. In addition to the copy function, there is also a function of connecting to a computer, which allows you to write on the electronic whiteboard and put the content on the whiteboard into the computer or print it out immediately.

[0047] Interactive whiteboards can communicate with computers. Connect the whiteboard to a PC and use a projector to project the content on the PC onto the whiteboard screen. At this time, the whiteboard is equivalent to a large handwriting board, on which you can write and draw anything and display it on the PC instantly. The files are saved as graphic files. The PC can be connected to printers, digital booths and other devices to achieve instant recording of video display, physical display, printing, etc. If a specific application such as MICROSOFT's NETMEETING is used, the interactive whiteboard can communicate with other offices and conference rooms through the network to achieve network conferencing.

[0048] Optical electronic whiteboard is an advanced educational or conference-assisted human-computer interaction device. It can be used with projectors, computers and other tools to achieve functions such as dust-free writing, casual writing, and remote communication. It is not affected by strong light in front of the screen, has high touch accuracy, and writes smoothly. It can be completely consistent with normal writing habits without any delay. It is widely used in schools, training, and conferences.

[0049] In some embodiments, the electronic whiteboard detects the presence of a user in real time through a human body sensing sensor.

[0050] It should be noted that the human body induction sensor is a sensor based on the microwave Doppler principle, with a planar antenna as the induction system and a microprocessor as the control. The human body induction sensor transmits and receives at a microwave frequency of 10.525GHz. The human body induction sensor uses non-contact detection, with stable performance and long life. The sensor is not affected by temperature, humidity, noise, airflow, dust, light, etc., and is suitable for harsh environments. It has strong anti-RF interference ability and strong penetration ability. It is small in size and easy to install flexibly.

[0051] Step 102: If it is detected that the user is absent for a time period exceeding a first preset threshold, the use status parameters of the electronic whiteboard are adjusted.

[0052] In some embodiments, if it is set to automatic mode, when it is detected that the user is not present for a time exceeding a first preset threshold, the usage status parameters of the electronic whiteboard are automatically and gradually adjusted; if it is set to manual mode, when it is detected that the user is not present for a time exceeding a first preset threshold, the usage status parameters of the electronic whiteboard set by the user are maintained.

[0053] In some embodiments, the usage status parameters of the electronic whiteboard include screen brightness and speaker volume.

[0054] Specifically, when the built-in system of the electronic whiteboard is started, the presence of the user is detected through the human body sensing sensor. Next, the system initializes the human body sensing mode and the first preset threshold (WAITING time). The default first preset threshold is set to the time period preset at startup, and the human body sensing mode is initialized according to the last system status. If the current human body sensing mode is manual mode, the system will maintain the screen brightness and speaker volume manually set by the user, and will not automatically adjust. The first preset threshold can be set to 10 seconds. If the current human body sensing mode is set to automatic mode, when it is detected that the user is not present for more than 10 seconds, the screen brightness and speaker volume of the electronic whiteboard are automatically and gradually reduced.

[0055] In some embodiments, automatically and gradually reducing the screen brightness and speaker volume of the electronic whiteboard is expressed by the following formula 1:

[0056] Rrightness new =Rrightness initial ×f(x) Formula 1;

[0057] Among them, Rrightness new is the adjusted screen brightness, Rrightness initialis the initial screen brightness, f(x) is the time function, and the screen brightness gradually decreases as the user's absence time increases.

[0058] In some embodiments, when it is detected that the user is absent for a time exceeding a third preset threshold, the electronic whiteboard enters a sleep mode and turns off the screen brightness and speaker volume. Specifically, the third preset threshold can be set to 5 minutes, 10 minutes, or 15 minutes, etc.

[0059] Step 103: if it is detected that the user's presence time exceeds a second preset threshold, the electronic whiteboard is restored to the usage state parameters before the user leaves.

[0060] Specifically, the second preset threshold may be set to 10 seconds. If the presence of the user is detected for more than 10 seconds, the screen brightness and speaker volume of the electronic whiteboard are restored to the level before the user left.

[0061] In some embodiments, the use status of the human body sensing sensor is periodically detected, and if a failure of the human body sensing sensor is detected, the use status of the electronic whiteboard is restored to the state before the failure of the human body sensing sensor.

[0062] Specifically, when the built-in system of the electronic whiteboard detects that the human body sensing sensor fails, the electronic whiteboard is set from the human body sensing mode to the failure mode (DISABLE), and the screen brightness and speaker volume of the electronic whiteboard are restored to those before the human body sensing sensor fails.

[0063] In some embodiments, if a human body sensing sensor is detected to have a fault, fault information is sent to a user and a maintainer.

[0064] In some embodiments, when the power state of the electronic whiteboard changes, the use state of the electronic whiteboard before the power state of the electronic whiteboard changes is restored.

[0065] Specifically, when the power of the electronic whiteboard is turned off or restarted, the screen brightness and speaker volume of the electronic whiteboard before the power state of the electronic whiteboard is changed are restored.

[0066] It should be noted that in each of the above steps, the built-in system of the electronic whiteboard needs to perform the following condition judgments: determine whether the sensor is working normally and whether the user is detected; determine whether the unmanned time exceeds the set threshold; determine whether the human body sensing mode is automatic or manual; determine whether the continuous presence time exceeds 10 seconds; determine whether the sensor status is normal; determine whether the power status has changed.

[0067] [Example 2]

[0068] like Figure 3As shown, this embodiment provides an electronic whiteboard adjustment system, including:

[0069] The user status detection module 201 is used for the electronic whiteboard to detect in real time whether a user exists. It should be noted that the user is the user who uses the electronic whiteboard.

[0070] Specifically, the electronic whiteboard may be a copy-type electronic whiteboard, an interactive electronic whiteboard, or an optical electronic whiteboard.

[0071] The copy-type electronic whiteboard can scan and print out the content written on the whiteboard in a certain way through simple operations of the user. Its function completion process is the same as the ordinary copy process. First, the image sensor collects the content on the whiteboard. After the collected signal undergoes certain image processing, it is finally output by thermal, inkjet or other printing methods. The printing output methods generally include thermal paper output and inkjet ordinary paper output, and the colors are black and white and color output. In addition to the copy function, there is also a function of connecting to a computer, which allows you to write on the electronic whiteboard and put the content on the whiteboard into the computer or print it out immediately.

[0072] Interactive whiteboards can communicate with computers. Connect the whiteboard to a PC and use a projector to project the content on the PC onto the whiteboard screen. At this time, the whiteboard is equivalent to a large handwriting board, on which you can write and draw anything and display it on the PC instantly. The files are saved as graphic files. The PC can be connected to printers, digital booths and other devices to achieve instant recording of video display, physical display, printing, etc. If a specific application such as MICROSOFT's NETMEETING is used, the interactive whiteboard can communicate with other offices and conference rooms through the network to achieve network conferencing.

[0073] Optical electronic whiteboard is an advanced educational or conference-assisted human-computer interaction device. It can be used with projectors, computers and other tools to achieve functions such as dust-free writing, casual writing, and remote communication. It is not affected by strong light in front of the screen, has high touch accuracy, and writes smoothly. It can be completely consistent with normal writing habits without any delay. It is widely used in schools, training, and conferences.

[0074] In some embodiments, the electronic whiteboard detects the presence of a user in real time through a human body sensing sensor.

[0075] It should be noted that the human body induction sensor is a sensor based on the microwave Doppler principle, with a planar antenna as the induction system and a microprocessor as the control.

The sensor is not affected by temperature, humidity, noise, airflow, dust, light, etc., and is suitable for harsh environments. It has strong anti-RF interference ability and strong penetration ability. It is small in size and easy to install flexibly.

[0076] The first logic judgment module 202 is used to judge whether the user's absence time exceeds a first preset threshold, and if it exceeds the first preset threshold, adjust the use status parameters of the electronic whiteboard.

[0077] In some embodiments, if it is set to automatic mode, when it is detected that the user is not present for a time exceeding a first preset threshold, the usage status parameters of the electronic whiteboard are automatically and gradually adjusted; if it is set to manual mode, when it is detected that the user is not present for a time exceeding a first preset threshold, the usage status parameters of the electronic whiteboard set by the user are maintained.

[0078] In some embodiments, the usage status parameters of the electronic whiteboard include screen brightness and speaker volume.

[0079] Specifically, when the built-in system of the electronic whiteboard is started, the presence of the user is detected through the human body sensing sensor. Next, the system initializes the human body sensing mode and the first preset threshold (WAITING time). The default first preset threshold is set to the time period preset at startup, and the human body sensing mode is initialized according to the last system status.

The first preset threshold can be set to 10 seconds. If the current human body sensing mode is set to automatic mode, when it is detected that the user is not present for more than 10 seconds, the screen brightness and speaker volume of the electronic whiteboard are automatically and gradually reduced.

[0080] In some embodiments, automatically and gradually reducing the screen brightness and speaker volume of the electronic whiteboard is expressed by the following formula 1:

[0081] Rrightness new =Rrightness initial ×f(x) Formula 1;

[0082] Among them, Rrightness new is the adjusted screen brightness, Rrightness initial is the initial screen brightness, f(x) is the time function, and the screen brightness gradually decreases as the user's absence time increases.

[0083] In some embodiments, when it is detected that the user is absent for a time exceeding a third preset threshold, the electronic whiteboard enters a sleep mode and turns off the screen brightness and speaker volume. Specifically, the third preset threshold can be set to 5 minutes, 10 minutes, or 15 minutes, etc.

[0084] The second logic judgment module 203 is used to judge whether the user's presence time exceeds a second preset threshold, and if it exceeds the second preset threshold, restore the electronic whiteboard to the usage state parameters before the user leaves.

[0085] Specifically, the second preset threshold may be set to 10 seconds. If the presence of the user is detected for more than 10 seconds, the screen brightness and speaker volume of the electronic whiteboard are restored to the level before the user left.

[0086] The sensor detection module 204 is used to periodically detect the use status of the human body sensing sensor.

[0087] In some embodiments, the use status of the human body sensing sensor is periodically detected, and if a failure of the human body sensing sensor is detected, the use status of the electronic whiteboard is restored to the state before the failure of the human body sensing sensor.

[0088] Specifically, when the built-in system of the electronic whiteboard detects that the human body sensing sensor fails, the electronic whiteboard is set from the human body sensing mode to the failure mode (DISABLE), and the screen brightness and speaker volume of the electronic whiteboard are restored to those before the human body sensing sensor fails.

[0089] In some embodiments, if a human body sensing sensor is detected to have a fault, fault information is sent to a user and a maintainer.

[0090] The power detection module 205 is used to detect the power status in real time.

[0091] Specifically, when the power of the electronic whiteboard is turned off or restarted, the screen brightness and speaker volume of the electronic whiteboard before the power state of the electronic whiteboard is changed are restored.

[0092] It should be noted that in each of the above steps, the built-in system of the electronic whiteboard needs to perform the following condition judgments: determine whether the sensor is working normally and whether the user is detected; determine whether the unmanned time exceeds the set threshold; determine whether the human body sensing mode is automatic or manual; determine whether the continuous presence time exceeds 10 seconds; determine whether the sensor status is normal; determine whether the power status has changed.
