All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a distributed audio and video control system which can control audio and video equipment in different regional control systems across regions.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Fig. 1 is a structural diagram of a distributed audio/video control system provided in the present invention, and as shown in fig. 1, a distributed audio/video control system includes: a plurality of area control systems 1 and a plurality of area control system hosts 2; one of the zone control systems 1 corresponds to one of the zone control system hosts 2; each of the zone control systems 1 comprises a plurality of audio-video devices 9; the regional control system host 2 is used for controlling the audio and video equipment 9; a plurality of regional control system hosts 2 carry out information interaction through a network protocol 3; the regional control system host 2 in different regions utilizes the network protocol 3 to control the audio and video equipment 9 across regions.
In practical applications, the area control system host 2 includes: a network interface 4; the network interface 4 of each of the regional control system hosts 2 is used for information interaction through the network protocol 3.
In practical applications, each of the network interfaces 4 communicates with each other through a network cable.
In practical applications, the area control system host 2 further includes: a serial Communication (COM) interface; the COM interface is used for connecting an audio and video device 5 controlled by COM.
In practical applications, the area control system host 2 further includes: an Infrared (IR) interface; the IR interface is used to connect to an infrared controlled audio-video device 6.
In practical applications, the area control system host 2 further includes: a Relay (REL) interface; the REL interface is used for connecting the audio and video equipment 7 controlled by the relay.
In practical applications, the network Protocol 3 includes a Transmission Control Protocol/Internet Protocol (TCP/IP) Protocol, a User Datagram Protocol (UDP) Protocol, and an inter-system communication Protocol.
In practical application, the invention also comprises: a touch display screen 8; and the regional control system host 2 in different regions controls the audio and video equipment 9 by using the network protocol 3 across regions through the touch display screen 8.
In fig. 1, the devices in the area a, the area B and the area C are the same, each area is provided with an area control system host 2, the area control system host 2 includes a network interface 4, a COM interface, an infrared interface, a relay interface and the like, and each area control system host 2 can control the audio and video device 9 in the area through a network device (such as a touch display screen 8).
Meanwhile, the control of each area device is realized through programming, in the programming, each controlled host computer is controlled through programming, programming software has a multi-user management function and can authorize a plurality of users, each user controls an authorized area, and the unauthorized area cannot be controlled. The software administrator authorizes the users, each user has a password, multiple users can be authorized, and different users manage and control different areas.
A. B, C, and exchanging information via the communication protocol of the interns system. The control host in the area A can control all the devices in the three areas A \ B \ C, similarly, the host in the area B can control all the devices in the three areas A \ B \ C, and the host in the area C can also control all the devices in the three areas. The controller has no primary and secondary points, is completely distributed, and forms a complete large network control system.
The areas are directly controlled by the protocol without passing through a server device, are distributed and have no primary and secondary scores. Therefore, the problem that the main equipment is broken to cause that other areas cannot be controlled does not exist, and the disaster recovery backup capability is greatly improved.
The control protocol is the same from area to area, without primary and secondary points, but the management operation authority can be authorized by programming, different login users adopt different passwords and different management authorities.
