Central control system for remotely controlling exhibition hall

Abstract

The invention relates to a central control system for remotely controlling an exhibition hall. The central control system comprises a remote control terminal, a central control host, a relay and clients, wherein the remote control terminal is connected with the central control host; the central control host is connected with the relay and the clients respectively; the relay is connected with the client; the remote control terminal transmits a required instruction to the central control host; the central control host performs starting and shutdown operation on the clients through the relay, and transmits a command to the clients according to the required instruction after the clients are started; the clients execute the required instruction after receiving the command. Compared with the prior art, the central control system has the advantages that the central control system is low in implementation cost and high in reliability; equipment can be regulated according to the size and environment of the exhibition hall, so that the central control system is wide in application range and high in pertinence; a client / server mode is adopted, and the number of the clients can be conveniently and rapidly increased, so that the central control system is high in extensibility and easy to maintain.

Description

technical field [0001] The invention relates to a central control system, in particular to a central control system for remote control of an exhibition hall. Background technique [0002] With the continuous development of society, information exchange and communication will become more frequent and more important. Various audio-visual equipment, projection equipment, conference systems, etc. began to enter all walks of life. The current conference room, audio-visual teaching room, etc. are no longer a podium, a chair, and a microphone, but replaced by various advanced multimedia conference and teaching equipment. Such as: projectors, DVD players, video recorders, video display stands, multimedia computers, electric screens, and some large conference rooms are also equipped with simultaneous interpretation systems, electronic voting systems, large-screen projections, and multi-screen switching systems. The use of multiple devices will inevitably bring complicated device op...

AI Technical Summary

Problems solved by technology

However, the general flow of people in the exhibition hall is relatively small, and the display equipment in the exhibition, especially the display equipment, is basically turned on around the clock during the exhibition period, and the promotional videos are played continuously, which causes unnecessary power consumption when no one visits for a long time

Moreover, the display system of general exhibition organizations is controlled manually, which makes the cost of manpower input relatively large, and it is impossible to automatically turn on and off each device
