Jiangxi Radio And TV Monitoring Network System Design And Implementation

The current, The development of digital broadcasting and TV is in full swing, Radio and TV technology has been a breakthrough,.The foreign developed countries have gradually stopped ground simulation TV broadcast, The country has also ground to a halt the analog cable TV broadcast, Wireless simulation is also gradually shutting down.Compared with abroad, China’s radio and television has been a mouthpiece of the party and the government, as an important mainstream media, is an important propaganda tool, the party and the government of our country level is higher than that of other countries to the attention of the broadcasting and television, radio and TV regulation work also pay more attention to than abroad, Radio and television monitoring of our country starts relatively early, Medium short wave radio monitoring began in 1955, Terrestrial television and FM radio monitoring began in 1987, Satellite TV monitoring began in 1995, Cable TV monitoring began in 2002Medium wave radio monitoring is mainly implemented anomaly alarm, the problems of audio recording, automatic spectrum scanning, signal real-time measurement and data storage, and other functions; Shortwave radio monitoring, due to the particularity of its transport, major radio power generally USES the method of combining the local and remote monitoring, complete field intensity of signals, the transmission frequency, amplitude, frequency spectrum usage information collection; FM radio is used most widely voice broadcasting, monitoring of FM radio mainly measuring parameters such as signal level, signal interference, the automatic alarm system for the anomaly, complete FM frequency spectrum scanning at the same time, eliminate interference signal, to find a new frequency point; TV including analog television and digital television monitoring.Jiangxi radio and TV monitoring, began in 1984, with manual monitoring is given priority to, before 2000, building a set of simulation of wireless radio and television monitoring system, construction began in 2011 in jiangxi province, the provincial radio and TV monitoring network, the project contains two parts, the monitoring network has been basically completed, the construction of the provincial radio and TV monitoring network, the jiangxi radio and TV monitoring automation, intelligent and network level improved significantly.
