Exhibition hall equipment and multimedia centralized control system

Abstract

The invention discloses an exhibition hall equipment and multimedia centralized control system. The exhibition hall equipment and multimedia centralized control system comprises a main controller, a serial server, controlled end equipment and an intelligent control server, wherein the main controller consists of an operation panel, a PC (Personal Computer), an iPad, a mobile phone and an Android host; the operation panel is connected with the intelligent control server; the switching value signal of the operation panel is converted into a network signal through the intelligent control server, and is transmitted to the serial server; the PC, the iPad, the mobile phone, the Android host and the intelligent control server transmit signals to the serial server through a network; the serial server is used for forwarding the signals to controlled ends; the controlled ends refer to a projector, a power amplifier, a power controller, a computer and a plurality of multimedia. The exhibition hall equipment and multimedia centralized control system provided by the invention has the advantages of low cost, high stability and simple circuit. Bidirectional control can be realized between the PC and the iPad, so that great convenience is brought to use.

Description

technical field [0001] The invention relates to exhibition hall equipment and a multimedia centralized control system. Background technique [0002] With the continuous development of society, information exchange and communication 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, VCRs, 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 equipment operations. It is necessary to turn on the power of var...

Problems solved by technology

The central control host has many functions, but the manufacturing cost is very high. All equipment must be directly connected to the central control host. The laying of various lines is complicated and the installation is very troublesome. Due to the limited interface of the central control host, the scalability is relatively poor and the functions are also limited. , unable to support various expansive controls for large and complex exhibition halls. Since the host signal is forwarded through the central control host, the central control host is more complicated, so the stability is poor, and it is prone to crashes
