[0002] The administrator’s remote monitoring of the digital signage terminal basically uses screenshots to check whether the terminal is working normally, and the screenshot is to intercept the image signal in the framebuffer of the Android system, and then the signal will be sent to the screen; but in reality, when When the power supply system for the screen fails, the administrator can also intercept the image of the system running, and think that the terminal is working normally at this time, resulting in wrong information about the terminal running status

Embodiment
[0048] see figure 1 , figure 1 It is a schematic flowchart of a method for detecting the screen running state of a digital signage in an embodiment of the present invention.
[0049] Such as figure 1 As shown, a method for detecting the screen running state of a digital signage, the method includes:
[0050] S11: Based on the MCU, respectively detect whether the backlight voltage of the screen, the TCON power supply voltage of the screen, and the LVDS signal are abnormal, and obtain corresponding detection results;
[0051]In the specific implementation process of the present invention, the MCU-based detection of the backlight voltage of the screen, the TCON supply voltage of the screen and the LVDS voltage of the screen are abnormal, including: detecting the backlight voltage of the screen and the voltage of the screen based on the GPIO on the MCU. Whether the TCON power supply voltage is abnormal, and based on the digital-to-analog converter on the MCU converting the LVDS...

The invention discloses a digital signage screen running state detection method and device and a digital signage, wherein the method comprises the following steps that whether the backlight voltage ofthe screen, the TCON power supply voltage of the screen and the LVDS signal are abnormal or not are respectively detected based on the MCU, and corresponding detection results are acquired; the MCU sends the corresponding detection result to a main control board in the digital signage; the main control board in the digital signage receives a screenshot instruction sent by a management terminal, responds to the screenshot instruction, and captures the current FrameBuffer content to generate a picture; and the main control board in the digital signage sends the picture and the corresponding detection result to the management terminal based on HTTPS. According to the embodiment of the invention, the manager can be accurately assisted to judge the running state of the terminal screen, the misjudgment rate is reduced, and the good running of the terminal screen is ensured.
Description
technical field [0001] The invention relates to the technical field of screen state detection, in particular to a method and device for detecting the screen running state of a digital signage and a digital signage. Background technique [0002] The administrator’s remote monitoring of the digital signage terminal basically uses screenshots to check whether the terminal is working normally, and the screenshot is to intercept the image signal in the framebuffer of the Android system, and then the signal will be sent to the screen; but in reality, when When the power supply system for the screen fails, the administrator can also intercept the image of the system running, and think that the terminal is working normally at this time, resulting in wrong information about the terminal's operating status. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art. The present invention provides a digital signage screen ...
