Whether the state for the server that the first visible light communication signal received is represented exceedes the threshold values, when more than institute
Threshold values is stated, the second visible light communication signal of the state for controlling the server is generated, and passes through second visible ray
Communication module is sent to outside.
That is, the status information that described display control apparatus can be received with automatic decision, when wherein certain status information exceedes pair
After the threshold values answered, early warning can be provided, while control instruction can be sent automatically, is controlled by the system administration in server
Device or baseboard management controller are controlled to the various states of server.
Further, display control apparatus includes signal conversion module；
Described control unit, the electric signal specifically for first generating the state for controlling the server, is then utilized
The electric signal is converted to the second visible light communication signal by the signal conversion module, and passes through second visible ray
Communication module is sent to outside.
Further, the second visible light communication module also includes visible light communication sending module, the optic communication hair
Module is sent to include coding unit, LED drive circuit and LED, the carrier frequency pair that coding unit is set according to the second control signal
The second visible light communication signal is encoded, and is sent to LED drive circuit, and the LED drive circuit will be used for after encoding
The second visible light communication signal be added on the LED to outside transmission.
Further, the second visible light communication module can also include the optical system, it is seen that optic communication signal
It can first pass through after the optical system filters out interference signal and retransmit away.In this way, display control apparatus passes through coding unit
It will send after data encoding, encoded signal is added on LED and is transmitted by LED drive circuit, server is according to reception
The control instruction arrived carries out corresponding operating.
In technical solution of the present invention, display control apparatus can send control by line-of-sight propagation to server to be believed
Breath, makes System Management Controller or baseboard management controller in server adjust system or server according to control instruction
Working condition, such as adjust rotation speed of the fan, reduction main board work temperature.
In technical solution of the present invention, it is seen that optical communications module information is the important composition portion of server and display control apparatus
Point, the second visible light communication module in the first visible light communication module and display control apparatus in server can be used as phase
Isostructural standard visible light communication module is built in server and display control apparatus.Therefore following alleged ground visible ray leads to
Letter module claims for the generation of the first visible light communication module or the second visible light communication module.
Fig. 5 is visible light communication modular structure schematic diagram provided in an embodiment of the present invention, as shown in figure 5, visible light communication
Module includes visible light communication sending module, visible light communication receiving module.Visible light communication sending module passes through coding unit
