Abstract

The invention provides an intelligent integrated control system for the electrical elevation of liquid crystal lifters and projectors, which comprises a master control board subsystem, 232 communication control interfaces and an external control subsystem. The master control board subsystem consists of a power supply module, a SCM information processing module, a relay group and a remote control module. The external control subsystem can control the master control board in the modes of touch screen control, manual central control and remote control. One end of the master control board subsystem is connected with a power input terminal, and the other end thereof is connected with the external control subsystem. The master control board subsystem is connected with an upper travel switch, a lower travel switch, an optical coupling controller, a turn angle motor and an elevation master motor respectively. The master control board subsystem has a 232 communication control interface, which is the communication control interface capable of or free of information feedback and connected with the 232 communication interface of a computer. The invention has the advantages of good stability, intelligence and strong compatibility, easy operation and high control efficiency.

Description

technical field [0001] The invention relates to a control system of multimedia audio-visual equipment, in particular to an intelligent integrated control system for electric lifting of a liquid crystal lifter and a projector. Background technique [0002] Due to the relatively late start of China's multimedia video conferencing (teaching) system, the current lifting control intelligence is low, the button control is not in good contact, there is no communication serial port RS232 control and the feedback of machine operation information is slow, and it cannot be integrated with the international multimedia video conferencing (teaching) system. compatible. According to the statistics of Chinese industry insiders, more than 80% of multimedia video conferencing (teaching) systems currently have the problems of poor contact of button control, buttons that cannot be reset, and control that is easy to lose frequency, which leads to low efficiency of system control and even invalid...
