Problems solved by technology

[0002] With the application of LED display screens more and more widely, all kinds of LED displays, especially outdoor LED displays are very susceptible to the influence of the environment, and various environmental factors change with time The influence of illuminance, when the illuminance value is relatively large, if the brightness of the LED display is not enough, the display content of the LED display is not clear, but if the brightness of the LED display is too large, it will cause waste of energy and increase the cost of use. increase; for another example, subject to the influence of ambient temperature and ambient humidity, such as high temperature or high humidity, it is easy to damage the parts of the LED display
[0003] In the prior art, the environmental monitors generally used in LED display screens are used alone, that is, the environmental factors around the LED display screen are detected by an independent environmental monitor, and then the LED display screen is adjusted by human operation to detect and adjust The operation is complicated, the detection method is not flexible enough, and the adjustment accuracy is relatively low

Embodiment 1

[0025] Such as figure 1 As shown, this embodiment provides an LED display screen environmental monitoring system, the environmental monitoring system includes a control device and an environmental monitoring device, the LED display screen environmental monitoring system can be used to detect various LED display screens The influence factors of the surrounding environment, and, according to the influence of each influence factor on the LED display screen, control the brightness of the LED display screen, so that the brightness of the LED display screen is consistent with the contrast of the ambient brightness, so as to achieve energy saving. Make the LED display display effect better.

[0026] Wherein, the control device is provided with a control unit, the control unit is directly connected with various LED display screens, the control signal is input through the control unit, and the control unit processes the control signal to generate the first Display data for display on ...

Embodiment 2

[0044] Such as figure 2 As shown, applied to the above examples and combinations thereof, in the LED display screen environmental monitoring system provided by this embodiment, a switching control unit is set in the environmental monitor, and a corresponding switching module is set in the current loop probe, through The switching control unit controls the switching module, so as to switch the current loop probe to detect the ambient temperature, or the ambient humidity, or the ambient illuminance.

[0045] For example, a switch button for switching can be set in the environmental monitor, or a switch input terminal can be set, and the switch module of the current loop probe can be controlled by inputting instructions through the switch button or the switch input terminal, so that the current The ring probe can respectively detect the temperature, humidity, illuminance and other influencing factors of the surrounding environment of the LED display screen, and the operation is ...

Embodiment 3

[0048] Such as image 3 As shown, applied to the above examples and combinations thereof, in the LED display screen environmental monitoring system provided by this embodiment, the environmental monitor is also connected to the LED display screen, and the environmental monitor is also set The second conversion unit converts the data value into the second display data through the second conversion unit, for example, the data value converted by the first conversion unit through DSP (Digital Signal Processing, digital signal processing) converted into the second display data containing the influencing factors, and sending the second display data to the LED display screen for display, that is, the values ​​of the environmental influencing factors detected by the environmental monitoring device can be Displayed on the LED display screen, for example, the ambient temperature or / and ambient humidity or / and ambient illuminance are displayed on the LED display screen.

[0049] In this...
