[0041] [Example 1]

[0042] The inventor of this solution found that in the prior art, there is a lack of an effective way to record and manage the maximum continuous use time of the LED backlight, and users cannot well control the service life of the electronic whiteboard when using it. Moreover, when the user exceeds the product specifications and continuously uses the electronic whiteboard LED backlight for a long time, it is impossible to provide effective evidence to protect the rights and interests of the manufacturer. Embodiment 1 of the present invention provides the following solution:

[0043] like Figure 1 to Figure 2 As shown, this embodiment provides a method for monitoring the service life of an electronic whiteboard LED backlight, comprising:

[0044] Step 101, obtaining the working time of the LED backlight of the electronic whiteboard in real time, and accumulating the continuous working time of the LED backlight of the electronic whiteboard.

[0045] In some embodiments, when the electronic whiteboard is started, a time counter for timing the continuous working time of the electronic whiteboard LED backlight is initialized; after the initialization is completed, the power state of the electronic whiteboard is monitored in real time, and when the power state is in the working state and the electronic whiteboard LED backlight is turned on, the timing starts. It should be noted that the initial value of the time counter is set to zero, and the maximum countable time is set to 200,000 hours.

[0046] In some embodiments, when the LED backlight of the electronic whiteboard is turned off, the time counter stops the current timing. When the LED backlight of the electronic whiteboard is turned on again, the time counter resumes timing.

[0047] In some embodiments, after detecting that the electronic whiteboard LED backlight is turned on, the continuous working time of the current electronic whiteboard LED backlight begins to be accumulated. The time counter is updated after a certain period of time, and the current accumulated continuous working time is recorded in the time counter. It is understandable that the certain period of time can be a fixed time, such as every one minute, two minutes, etc.

[0048] Step 102, determining whether the current accumulated maximum continuous working time reaches a warning threshold or a life limit threshold.

[0049] In some embodiments, after each continuous working time is accumulated, the current accumulated maximum continuous working time is compared with the previously recorded maximum continuous working time. If the current accumulated maximum continuous working time is greater than the previously recorded maximum continuous working time, the current accumulated maximum continuous working time is updated by the following formula 1:

[0050] T current =T prev +Δt, Equation 1

[0051] Among them, T current is the current maximum continuous time, T prev is the maximum continuous time recorded before, and Δt is the time interval.

[0052] It should be noted that the continuous working time can be accumulated every minute, and the accumulated maximum continuous working time is recorded in the memory of the electronic whiteboard system. If the current accumulated maximum continuous working time is greater than the previously recorded maximum continuous working time, the electronic whiteboard system will update the maximum continuous working time in the memory.

[0053] Step 103: If the current accumulated maximum continuous working time reaches the warning threshold, a warning message is sent to the server.

[0054] In some embodiments, each time the current accumulated maximum continuous working time is updated, it is determined whether the current accumulated maximum continuous working time reaches the warning threshold. If the warning threshold is reached, a warning message is sent to the server, and after receiving the warning message, the server sends the warning message to the user terminal and the merchant terminal respectively. In some embodiments, a wireless transmission module is provided in the electronic whiteboard system, such as a cellular network, and the current accumulated maximum continuous working time is transmitted to the server through the cellular network.

[0055] In some embodiments, the terminal may be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile Internet device or other mobile terminal; wherein the terminal may be a device at the outermost periphery of a computer network, and may also be used for inputting information and outputting processing results, etc. It may also be referred to as a system, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a mobile terminal, a wireless communication device, a user agent, a user device, a plug-in-installable service device or a user equipment (UE). For example, the terminal may be a cellular phone, a mobile phone, a wireless phone, a smart watch, a wearable device, a tablet device, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, a vehicle-mounted communication module, a smart meter or other processing device connected to a wireless modem.

[0056] In some embodiments, the warning threshold can be set to 150,000 hours. When the continuous working time of the electronic whiteboard LED backlight reaches 150,000 hours, the warning information of the electronic whiteboard LED backlight continuously working for 150,000 hours is sent to the server. After receiving the warning information, the server sends the warning information to the user end and the merchant end respectively, so that users can fully understand the current usage of the electronic whiteboard, and can also remind manufacturers to understand the current service life of the electronic whiteboard, so as to facilitate its later maintenance and upgrading, and improve the user experience.

[0057] In other embodiments, the warning threshold can be set to 180,000 hours. When the continuous working time of the electronic whiteboard LED backlight reaches 180,000 hours, the warning information of the electronic whiteboard LED backlight continuously working for 180,000 hours is sent to the server. After receiving the warning information, the server sends the warning information to the user end and the merchant end respectively, so that the user can know in time that the life of the current electronic whiteboard is about to expire, and it can also remind the manufacturer to understand the current service life of the electronic whiteboard is about to expire, so as to take corresponding measures later.

[0058] Step 104: If the current accumulated maximum continuous working time reaches the life limit threshold, an alarm message is sent to the server.

[0059] For example, the life limit threshold can be set to 200,000 hours. When the continuous working time of the electronic whiteboard LED backlight reaches 200,000 hours, an alarm message of the electronic whiteboard LED backlight continuously working for 200,000 hours is sent to the server. After receiving the alarm message, the server sends the alarm message to the user end and the merchant end respectively, so that the user and the merchant can know in time that the current electronic whiteboard is about to expire.

[0060] In some embodiments, the electronic whiteboard system notifies the user of the maximum continuous working time of the LED backlight through a screen display. The user can view the current accumulated maximum continuous working time through the system interface in the display. When the system performs a factory reset, the time counter will be reset to zero, and the system will prompt the user that the time counter has been initialized. The user can confirm and continue the operation through the interface.

[0061] [Example 2]

[0062] like Figure 3 As shown, this embodiment provides an electronic whiteboard LED backlight service life monitoring system, including:

[0063] The acquisition module 201 is used to acquire the working time of the LED backlight of the electronic whiteboard in real time.

[0064] In some embodiments, when the electronic whiteboard is started, a time counter for timing the continuous working time of the electronic whiteboard LED backlight is initialized; after the initialization is completed, the power state of the electronic whiteboard is monitored in real time, and when the power state is in the working state and the electronic whiteboard LED backlight is turned on, the timing starts. It should be noted that the initial value of the time counter is set to zero, and the maximum countable time is set to 200,000 hours.

[0065] In some embodiments, when the LED backlight of the electronic whiteboard is turned off, the time counter stops the current timing. When the LED backlight of the electronic whiteboard is turned on again, the time counter resumes timing.

[0066] The accumulation module 202 is used to accumulate the continuous working time of the LED backlight of the electronic whiteboard.

[0067] In some embodiments, after detecting that the electronic whiteboard LED backlight is turned on, the continuous working time of the current electronic whiteboard LED backlight begins to be accumulated. The time counter is updated after a certain period of time, and the current accumulated continuous working time is recorded in the time counter. It is understandable that the certain period of time can be a fixed time, such as every one minute, two minutes, etc.

[0068] The judgment module 203 is used to judge whether the current accumulated maximum continuous working time reaches the warning threshold or the life limit threshold.

[0069] In some embodiments, after each continuous working time is accumulated, the current accumulated maximum continuous working time is compared with the previously recorded maximum continuous working time. If the current accumulated maximum continuous working time is greater than the previously recorded maximum continuous working time, the current accumulated maximum continuous working time is updated by the following formula 1:

[0070] T current =T prev +Δt, Equation 1

[0071] Among them, T current is the current maximum continuous time, T prev is the maximum continuous time recorded before, and Δt is the time interval.

[0072] It should be noted that the continuous working time can be accumulated every minute, and the accumulated maximum continuous working time is recorded in the memory of the electronic whiteboard system. If the current accumulated maximum continuous working time is greater than the previously recorded maximum continuous working time, the electronic whiteboard system will update the maximum continuous working time in the memory.

[0073] The warning information sending module 204 is used to send a warning message to the server if the current accumulated maximum continuous working time reaches the warning threshold.

[0074] In some embodiments, each time the current accumulated maximum continuous working time is updated, it is determined whether the current accumulated maximum continuous working time reaches the warning threshold. If the warning threshold is reached, a warning message is sent to the server, and after receiving the warning message, the server sends the warning message to the user terminal and the merchant terminal respectively. In some embodiments, a wireless transmission module is provided in the electronic whiteboard system, such as a cellular network, and the current accumulated maximum continuous working time is transmitted to the server through the cellular network.

[0075] In some embodiments, the terminal may be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile Internet device or other mobile terminal; wherein the terminal may be a device at the outermost periphery of a computer network, and may also be used for inputting information and outputting processing results, etc. It may also be referred to as a system, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a mobile terminal, a wireless communication device, a user agent, a user device, a plug-in-installable service device or a user equipment (UE). For example, the terminal may be a cellular phone, a mobile phone, a wireless phone, a smart watch, a wearable device, a tablet device, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, a vehicle-mounted communication module, a smart meter or other processing device connected to a wireless modem.

[0076] In some embodiments, the warning threshold can be set to 150,000 hours. When the continuous working time of the electronic whiteboard LED backlight reaches 150,000 hours, the warning information of the electronic whiteboard LED backlight continuously working for 150,000 hours is sent to the server. After receiving the warning information, the server sends the warning information to the user end and the merchant end respectively, so that users can fully understand the current usage of the electronic whiteboard, and can also remind manufacturers to understand the current service life of the electronic whiteboard, so as to facilitate its later maintenance and upgrading, and improve the user experience.

[0077] In other embodiments, the warning threshold can be set to 180,000 hours. When the continuous working time of the electronic whiteboard LED backlight reaches 180,000 hours, the warning information of the electronic whiteboard LED backlight continuously working for 180,000 hours is sent to the server. After receiving the warning information, the server sends the warning information to the user end and the merchant end respectively, so that the user can know in time that the life of the current electronic whiteboard is about to expire, and it can also remind the manufacturer to understand the current service life of the electronic whiteboard is about to expire, so as to take corresponding measures later.

[0078] The alarm information sending module 205 is used to send an alarm message to the server if the current accumulated maximum continuous working time reaches the life limit threshold.

[0079] For example, the life limit threshold can be set to 200,000 hours. When the continuous working time of the electronic whiteboard LED backlight reaches 200,000 hours, an alarm message of the electronic whiteboard LED backlight continuously working for 200,000 hours is sent to the server. After receiving the alarm message, the server sends the alarm message to the user end and the merchant end respectively, so that the user and the merchant can know in time that the current electronic whiteboard is about to expire.

[0080] In some embodiments, the electronic whiteboard system notifies the user of the maximum continuous working time of the LED backlight through a screen display. The user can view the current accumulated maximum continuous working time through the system interface in the display. When the system performs a factory reset, the time counter will be reset to zero, and the system will prompt the user that the time counter has been initialized. The user can confirm and continue the operation through the interface.
