Main and backup line switching system for radio frequency adapter and transmitter and implementation method thereof

Abstract

The invention discloses a radio frequency adapter and a transmitter main backup switching system and its implementation method, utilizes the "high speed" and "always online" characteristics of the GPRS wireless communication technology, and realizes the switching problem of the main backup line through the means of the network, so that The maintenance of the equipment will not occupy the user's use time, and the normal maintenance and repair of the equipment will be realized by switching between the main line and the backup line; the remote monitoring center will monitor the parameters of each part of the system in real time through the GPRS wireless monitoring unit, and through GPRS wireless monitoring The unit sends control instructions to each component to realize timely alarm and resolution of problems, which changes the traditional manual inspection method and saves human resources. The issue of human care.

Description

technical field [0001] The invention relates to a DTMB single-frequency network and a wireless transmitting system of the single-frequency network, in particular to a radio frequency adapter and a main backup switching system of a transmitter and a realization method thereof. Background technique [0002] As DTMB became the mandatory standard for terrestrial TV signals in China's broadcasting industry on August 1, 2007, all digital TV system suppliers that provide video transmission equipment for China's broadcasting industry will adopt the digital video modulation intellectual property (IP) in this standard. The scale of SFN is getting larger and larger, and the maintenance difficulty and workload of SFN transmitters also increase accordingly. The intelligent and networked active-standby switching system for transmitting equipment will surely become the mainstream of the future radio and television transmitting system. [0003] The transmitter is an important part of the D...

Problems solved by technology

At present, there are several shortcomings in the management of transmitters in radio and television in various places: (1) Transmitters are distributed in urban and rural areas, and the traditional manual inspection method can no longer meet the needs of rapid network development; (2) Lack of professional maintenance Staff, maintainers are of varying levels

Maintenance personnel cannot keep abreast of the operating status and failure phenomena of remote equipment in time, and cannot troubleshoot equipment failures in time; (3) Due to the wide distribution of transmitters, most of them are in remote rural areas, the surrounding environment is complex and unattended, and effective maintenance of equipment Monitoring and monitoring are particularly important. The traditional main-backup switching mechanism of the transmitter does not involve the main-backup switching of the RF adapter.
