Central control device and central control system

Abstract

The invention discloses a central control device and a central control system. The central control device comprises a controller and multiple function modules in coupling connection with the controller, wherein the multiple function modules comprise at least one from the following: a security protection early warning monitoring system module, a light control circuit module, a curtain control circuit module, an expansion circuit module, a communication circuit module, an identity identification circuit module, a classroom recording playing and remote monitoring circuit module, and a multimedia audio and video switching and curtain projection control circuit module. The central control device is characterized by further comprising a network device in coupling connection with the controller through a serial port which is configured to be connected with a network. The controller is configured to execute protocol conversion between serial port signals and network signals. The central control device and the central control system solve the problem that a controller in a conventional central control system cannot be connected with a network.

Description

technical field [0001] The invention relates to a central control system for multimedia education, in particular to a central control device and a central control system. Background technique [0002] With the advancement of science and technology, multimedia education born with the development of multimedia technology has gradually become the focus of school information construction, and multimedia classrooms have emerged as the times require. Multimedia classrooms are basically composed of PCs, projectors, curtains, multimedia central controllers and audio systems, especially the functions of the central controller will affect whether the entire system can work normally. As educational institutions are committed to modernizing education management, diversifying teaching methods, and intelligentizing teaching equipment, the requirements for multimedia education continue to increase. [0003] In the information age, it is required that electronic equipment should also be in...
