One-key signal switching control method of monitoring center

Abstract

A one-key signal switching control method of a monitoring center comprises the steps of connecting a comprehensive control terminal, a signal wire, a serial device server, an encoder and a decoder with a local area network, and transmitting a control instruction; connecting the signal wire with a video input end of the encoder or the input end of a matrix, and supplying a signal source; connecting the output end of the encoder with the input end of the decoder, and performing compression decoding of a video stream; connecting the output end of the decoder with the input end of the matrix, and transmitting the decoded video stream to the matrix; connecting the serial device server which is connected with the network with the matrix, and performing matrix switching; connecting the serial device server which is connected with the network with a screen display control server, and finishing screen controlling; connecting the screen display control server with a large screen; and realizing one-key switching of the signal to the large screen by the comprehensive control terminal through integrating encoder control, decoder control, matrix control and screen control.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a control method capable of one-button switching of monitoring signals of various units during monitoring. Background technique [0002] The core business of the monitoring center is mainly to realize the management and control of the frontline at the grassroots level. Through the access to the front-end and various monitoring data at the same level, it is collected in the upper-level monitoring center for processing and display. The signal switching control system is used as the internal equipment control and signal switching system of the border monitoring center, and is one of the most commonly used systems in the monitoring center. [0003] The monitoring center mainly includes a series of equipment such as display screen, screen display and control processor, computer signal switching matrix, video signal switching matrix, audio and video codec, etc. Among them, th...

Problems solved by technology

[0005] (1) The central control device cannot realize the integrated control of the codec and display screen mode: the central control host mainly realizes the device switching control through the serial port communication protocol of the integrated matrix and other equipment, but it is not easy to realize the integrated control of the codec. In addition, due to The screen mode is changeable, and the central control device cannot realize the integrated control of the screen display system

[0006] (2) Many central control devices or systems cannot realize one-button switching control: for example, in order to realize the display of video signals on the wall, it may be necessary to successively go through multiple processes such as encoder encoding control, decoder decoding control, matrix switching control, and screen display control. Steps and even multiple systems are coordinated to complete, and the operation is complex and cumbersome, which is a big challenge for operators with limited computer skills in the front line
