The control method of splicing system dual master control of the present invention, as shown in Fig. 2, including the following steps：
Step s101, according to the setting of user, the operating mode of dual master control is determined.
This method devises two kinds of operating modes：Independent working mode and cooperative work mode make two master controls both can be with
It works independently, and can cooperate.The right to choose of pattern then gives user, and user is according to the current demand of splicing system
The operating mode of dual master control is determined, if the currently stability of concern splicing system, selects cooperative work mode, if currently
It needs two combinations to show image, then selects independent working mode.
If step s102, being operated under cooperative work mode, master control 1 controls all lists according to the order at network-control end
Plate, and synchrodata is sent to master control 2 when state changes, so that the state of master control 2 is consistent with master control 1.
Above-mentioned master control 1 is not being distinguished structurally and functionally with master control 2, and 1 and 2 description, which is only made to distinguish, to be used.
Under cooperative work mode, the control work in two master controls, one execution system, one as backup.User can
To specify which master control as work master control while selecting cooperative work mode, which master control is used as backup master control.
As shown in figure 3, referring to work master control with master control 1, master control 2 refers to backup master control.
Two pieces of master control borads periodically can send keep-alive data to another piece of master control borad by serial ports, and keep-alive data include current
Output veneer, the IP of oneself that operating mode, display include send keep-alive data while can detect either with or without receiving another piece
The keep-alive data of master control borad.According to the content of the keep-alive data received, confirm the operating mode of another piece of master control, control it is defeated
Go out veneer and IP address etc..
Master control 1 is operated in cooperative work mode and is also operated in collaboration to other one piece of master control borad by keep-alive Data Detection
When pattern, configuration data or business can be changed by the synchrodatas such as data by serial ports when state changes and be sent to master control 2, it is main
After control 2 receives configuration synchrodata or business change synchrodata, the configuration using these data update current systems or industry
The corresponding states such as data of being engaged in need not carry out complicated business processing and also not need transmitting order to lower levels to veneer.Alternatively, first start
