Abstract

The invention relates to a dual-backup programmable central control system. The dual-backup programmable central control system comprises a main control module as well as a first control module and a second control module which are mutually independent, wherein the first control module and the second control module are connected with the main control module respectively; each of the first control module and the second control module correspondingly comprises a network module, a serial port module, a relay module, a digit module and an infrared module respectively, and the network modules, the serial port modules, the relay modules, the digital modules and the infrared modules correspondingly are connected with a network interface, a serial interface, a relay interface, digital input/output interfaces and infrared input/output interfaces respectively; the serial interface comprises a user control serial port and a programmable control serial port; and the main control module is connected with a power supply module and a touch control screen respectively. The dual-backup programmable central control system has complete functions and stable performance, is simple and convenient to use, and can meet the requirements of a high-end multimedia conferencing system for high stability, high reliability and the like.

Description

technical field [0001] The invention relates to a central control system, in particular to a double-backup programmable central control system. Background technique [0002] With the continuous development of society and science and technology, information exchange and communication have become more frequent and more important. Various audio-visual equipment, projection equipment and other equipment are gradually popularized, which has led to the rapid entry of conference control systems into all walks of life. The current conference room, audio-visual teaching room, etc. are no longer a single podium, a chair, and a microphone. Instead, they are 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, a...
