Embodiment
Refer to Fig. 1, Fig. 1 is the schematic flow sheet of the interconnected control method of combination of the present invention.
The interconnected control method of described combination comprises the following steps:
Step S101, arrange the shared demonstration data of local splicing wall control system;
The some or all of demonstration data of can calling of described local splicing wall control system are set to share the demonstration data according to actual needs, in order to share between a plurality of interconnected splicing wall control systems.Wherein, each data source that described demonstration data are connected by described local splicing wall control system provides.
Step S102, inquire about the connection profile of local splicing wall control system, obtains the list information that allows the strange land splicing wall control system that connects;
Set up corresponding connection profile in advance in each described splicing wall control system, set the list information that local splicing wall control system allows each strange land splicing wall control system of connection in described connection profile, and the list information that does not allow each strange land splicing wall control system of connection, wherein, described local splicing wall control system for example, is connected with several described strange land splicing wall control systems by communication network (the Internet or local area network (LAN)).
In a preferred implementation, only set the list information that local splicing wall control system allows each strange land splicing wall control system of connection in described connection profile, each described strange land splicing wall control system of described connection profile record all allows described local splicing wall control system to connect; Any strange land splicing wall control system that described connection profile is not put down in writing does not allow described local splicing wall control system to connect.
Step S103, according to the list information of described strange land splicing wall control system, connect to each described strange land splicing wall control system request respectively;
After each described strange land splicing wall control system sends the request connected, the request connected if described obtains the response of described strange land splicing wall control system, successful connection; If the request connected described does not meet with a response, connection failure.Therefore, record respectively the connection state information of described local splicing wall control system and each described strange land splicing wall control system, and show described connection state information in the control interface of described local splicing wall control system, so that the local user can be known the connection status of each described strange land splicing wall control system and described local splicing wall control system in real time.
