Controlling terminal 3 is used for input control signal；
Server 4, for storing data information；
Environment information acquisition terminal 5, for acquiring environmental information；
The network switch 6 receives control signal, environmental information, data information for the transmission of network data, and transmitsTo industrial control host 2.
Environment information acquisition terminal 5 includes network environment information acquisition module and light sensation detection sensor, network environment letterBreath acquisition module and the signal of light sensation detection sensor pass through the network switch 6 and are transferred to industrial control host 2.Network environment information is adoptedCollection module can be docked with network weather forecast, acquire the information such as negative, fine, rain and the environmental information of PM2.5, as adjusting LEDThe basic information of 1 brightness of display board, light sensation detection sensor can acquire the brightness information of actual environment, as comprehensive adjustmentBasis.
Controlling terminal 3 includes line traffic control terminal 3 and wireless control terminal 3, and wired controlling terminal 3 can be using computerForm docking, carries out the input of control signal；Wireless control terminal 3 can be controlled using the docking of the forms such as mobile phone, PadThe input of signal.
A kind of display control method of 1 system of outdoor large LED display board, includes the following steps：
Step 1, by data information memory to server 4, including default display brightness standard value；
Step 2, environment information acquisition terminal 5 acquires environmental information, and environmental information is transmitted to by the network switch 6Industrial control host 2；
Step 3, industrial control host 2 obtains control display brightness reference value according to environmental information analytical calculation；
Step 4, control display brightness reference value and default display brightness standard is calculated according to step 3 in industrial control host 2Value association obtains control display brightness.
