Multimedia equipment control system

Abstract

The invention discloses a multimedia equipment control system. The control system comprises a main control device (1) for receiving and processing a control signal transmitted by a process controller (4), and controlled terminals (2) connected with multimedia equipment (3). The main control device (1) is connected with the plurality of controlled terminals (2) by a power line; the control signal processed by the main control device (1) is transmitted to the plurality of controlled terminals (2) in a power line carrier communication manner; and each controlled terminal (2) receives and identifies the control signal which belongs to the controlled terminal and transmits the control signal to the multimedia equipment (3) connected to the controlled terminal (2). By utilizing wireless communication and power line carrier communication techniques, the multimedia equipment control system disclosed by the invention realizes wirelessness, convenience in installation and low cost of the control system.

Description

technical field [0001] The invention relates to a multimedia device control system, in particular to a system for intelligently controlling various multimedia devices by using wireless communication and power line carrier communication technology. Background technique [0002] With the continuous advancement of science and technology, intelligence has become a constant pursuit of people. At present, the existing multimedia equipment control system is mainly composed of three parts: user interface, central control host, and controlled equipment, and usually adopts communication methods such as RS232, RS485, infrared, and network. [0003] Among them, the user interface mainly uses buttons or remote controllers to control the signal of the central controller, and the central control host controls the controlled equipment through various control interfaces, usually by setting up a network to control the controlled equipment. Although this method achieves a certain degree of in...

AI Technical Summary

Problems solved by technology

Although this method achieves a certain degree of intelligence, it greatly limits the user's operating space through the button method, and the control of various controlled devices by the central control host is attached to the network, and the work of setting up the network is time-consuming and laborious. , and the location of the controlled device is greatly restricted

[0004] For example, when it is necessary to perform integrated control of various multimedia devices in the exhibition hall, it is first necessary to set up a huge master control device in the exhibition hall, and to lay out many communication lines between the master control device and various multimedia devices, which is costly and ineffective. good

In addition, when the exhibition hall needs to be remodeled, it will face the problem of dismantling these main control devices and communication lines, which causes a lot of inconvenience to the rearrangement of the exhibition hall
