Abstract
The invention discloses a method for displaying a composite image on a spliced display screen. A spliced display screen, a control computer and an external matrix switch constitute a display system; a database of the corresponding relation between the built-in image processing modules of different display screen units and the external matrix switch is established, so that the input signal of the external matrix switch is directly related to the serial number of the built-in image processing module, and the signal output ports of the external matrix switch can be connected with the built-in image processing modules in a random asymmetry way only through software settings without taking the middle output port into consideration. When a certain signal output port of the external matrix switch fails, the signal output port of the external matrix switch can be replaced, and the corresponding relation between the serial numbers of the built-in image modules and the serial numbers of the new signal output ports of the external matrix switch can be reset in the database, so as to clear the fault port, thereby greatly enhancing the redundancy and accessibility of the system.

Summary of the invention
Technical matters to be solved by this invention provides and realizes the method that combination image shows on a kind of mosaic display screen, can improve the redundancy and the accessibility of system, and the user can reduce maintenance cost in actual use simultaneously.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of method that on mosaic display screen, realizes the combination image demonstration; Form a display system by mosaic display screen, controlling computer and external matrix switch; Wherein said mosaic display screen comprises a plurality of display screen units; The signal input port of described external matrix switch is connected with external input signal; Be connected with the signal input end of the first order display screen unit of described mosaic display screen through the control signal output ends of control line described controlling computer; And successively the control signal output ends of upper level display screen unit is connected with the signal input end of next stage display screen unit through the control signal connecting line; Link to each other with described external matrix switch through the control signal output ends of an other control line simultaneously described controlling computer; Each signal output port of described external matrix switch is done to be connected arbitrarily with the signal input port of each display screen unit of described mosaic display screen; The numbering of the built-in image module that is arranged on different display units and the signal output part slogan of described external matrix switch are set up database at corresponding relation; When image zoom that carries out the pictures different processing module and displacement, call the corresponding relation data of this database simultaneously, make the corresponding external matrix switch delivery outlet of built-in image processing module of different numberings switch to input signal to display simultaneously.
Setting up database may further comprise the steps: 1. the built-in image processing module of each display unit is numbered; 2. design the corresponding data table, the sequence number of tables of data is each built-in image processing module numbering, and the content of tables of data is the delivery outlet of described external matrix switch.
When image zoom that carries out different built-in image processing modules and displacement; Call the tables of data in the database; The matrix delivery outlet is found in numbering retrieval through built-in image processing module; The sending metrix switching command links to each other the input signal that requires to show with corresponding built-in image processing module then, realizes the demonstration of various combination image on mosaic display screen.
Compared with prior art; The invention has the advantages that built-in image processing module and the database of external matrix switch corresponding relation through setting up different display screen units; Make the input signal and the direct correlation of built-in image processing module numbering of external matrix switch; Delivery outlet in the middle of need not considering needs only like this through software set and just can realize that each signal output port of external matrix switch does any asymmetric connection with each built-in image processing module; If a certain signal output port fault of external matrix switch; Can the built-in image module of respective display unit be connected with the idle signal output port of external matrix switch; And in database, reset the corresponding relation between the new signal output part slogan of built-in image module numbering and external matrix switch; The mouth of just can fixing a breakdown, thus the redundancy and the accessibility of system improved greatly.Method of the present invention need not considered the signal output port of external matrix switch when sending controling instruction, only need know the numbering of built-in image processing module, just can confirm the output of external matrix switch.
