Below for the particular circuit configurations from machine 20 shown in the particular circuit configurations of the main frame 10 shown in Fig. 4 and Fig. 5, do concrete discussion to the course of work of the mosaic screen that the utility model embodiment provides, details are as follows:
When user presses the button of main frame 10, on-off circuit 101 exports corresponding switching information to master controller 100 according to the operation of user, and master controller 100 generates corresponding coded message according to switching information.Wherein, what this switching signal was master controller 100 detect its corresponding line port and the change that/row port voltage occurs.Such as, when user presses the button of main frame 10, if when master controller 100 detects that the voltage of the first row port GPIO1 and first row port GPIO4 changes, then determine button that user presses corresponding be the first on-off element K1 in the on-off circuit 101 of main frame 10, and master controller 100 generates corresponding coded message according to the voltage of the first row port GPIO1 at the first on-off element K1 place to the voltage of first row port GPIO4.
Further, master controller 100 determines that the coded message generated belongs to numbering selection information or feature operation information.When master controller 100 judges the coded message of generation as numbering selection information, this numbering selects information to be sent to the first data pin 2 of main USB connector by the first data pin by master controller 100, and numbering selection information to be sent to the 1st from first of machine from the first data pin 2 of USB connector and the first data pin 2 of the second USB connector by the first data pin 2 by main USB connector.If this numbering selects information to be sent to the 1st the data receiver pin from controller 200 from machine 20 from first of machine 20 from the first data pin 2 of USB connector by the 1st, then information this numbering is selected to be sent to the 2nd from first of machine 20 from the first data pin 2 of USB connector and second from the first data pin 2 of USB connector from second of machine 20 from the first data pin 2 of USB connector for the 1st, by that analogy, numbering selection information to be sent to the N number of from first of machine from the first data pin 2 of USB connector and second from the first data pin 2 of USB connector by N-1 from the first data pin 2 of USB connector from second of machine 20, eachly from the first data pin 2 of USB connector, numbering selection information is sent to each data receiver pin from controller 200 from machine 20 from first of machine 20, eachly identify that the numbering that receives selects information from machine 20 from controller 200, with select identifiable design go out the corresponding numbering of numbering selection information from machine 20, select corresponding numbering after machine 20, corresponding numbering from machine 20 from controller 200 according to the feature operation information that master controller 100 sends control corresponding numbering from machine 20 perform switching on and shutting down operation, display operation or parameter adjustment operation.
If this numbering selects information to be sent to the 1st the data receiver pin from controller 200 from machine 20 from second of machine 20 from the first data pin 2 of USB connector by the 1st, then information this numbering is selected to be sent to the 2nd from second of machine 20 from the first data pin 2 of USB connector and first from the first data pin 2 of USB connector from first of machine 20 from the first data pin 2 of USB connector for the 1st, by that analogy, numbering selection information to be sent to the N number of from first of machine from the first data pin 2 of USB connector and second from the first data pin 2 of USB connector by N-1 from the first data pin 2 of USB connector from first of machine 20, eachly from the first data pin 2 of USB connector, numbering selection information is sent to each data receiver pin from controller 200 from machine 20 from second of machine 20, eachly identify that the numbering that receives selects information from machine 20 from controller 200, with select identifiable design go out the corresponding numbering of numbering selection information from machine 20, select corresponding numbering after machine 20, corresponding numbering from machine 20 from controller 200 according to the feature operation information that master controller 100 sends control corresponding numbering from machine 20 perform switching on and shutting down operation, display operation or parameter adjustment operation.
Further, when master controller 100 judges the feature operation information of coded message as main frame 10 generated, main frame 10 generates original state detection signal according to user operation, and detect whether N number of state from machine 20 is original state according to this original state detection signal, if N number of state from machine 20 is original state, then main frame 10 control N number of from machine 20 perform corresponding switching on and shutting down operation, display operation or parameter adjustment operation; When main frame 10 detects that N number of state from machine 20 is not original state, then corresponding switching on and shutting down operate front selected the performing from machine 20 of host computer control power-off last time, display operates or parameter adjustment operates.It should be noted that, in the present embodiment, feature operation information to be sent to N number of detailed process from machine 20 and above-mentioned master controller 100 by main USB connector by master controller 100, and by main USB connector, numbering selection information to be sent to N number of process from machine 20 identical, repeats no more herein.
In addition, when user operation is when pressing the function key from machine 20, from the second data pin output encoder solicited message from controller 200 of machine 20, and be sent to the second data pin 3 of the main USB connector of main frame 10 from the second data pin 3 or the second of USB connector from the second data pin 3 of USB connector by first, this encode request information is sent to the second data pin of master controller 100 by the second data pin 3 of main USB connector, the master controller 100 of main frame 10 carries out recompile to what need to encode from machine 20 according to the encode request information received, and after carrying out recompile, the numbering that main frame 10 inputs according to user select operation select corresponding numbering from machine 20, and main frame 10 select corresponding numbering after machine 20, according to user input feature operation information control corresponding numbering from machine 20 perform switching on and shutting down operation, display operation or parameter adjustment operation.
In the utility model, mosaic screen comprise main frame 10 with N number of from machine 20, N be greater than 1 positive integer, N number of have small size display screen curtain from facility.Main frame 10 works from machine 20 according to user operation control is N number of, when main frame 10 detects user operation for pressing main frame 10 numbering options button, main frame 10 generates numbering selection information, and according to numbering selection information select corresponding numbering from machine 20, main frame 10 select corresponding numbering after machine 20, main frame 10 according to the feature operation information that user inputs control corresponding numbering from machine 20 perform switching on and shutting down operation, display operation or parameter adjustment operation, make in the occasion needing oversize display device, only use utility model provide by multiple mosaic screen from machine 20 cascade with small size display screen curtain, without the need to buying new oversize display device, reduce cost, and then solve existing large scale display screen and there is the high problem of cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
