Description

Multichannel FM broadcasting emission system

Technical field

The utility model relates to a kind of broadcast transmission system, especially a kind of multichannel FM broadcasting emission system.

Background technology

The construction and the application of nearly 2 years radio and television broadcasting satellite causes have fundamentally solved the covering problem of " frontier and poor " regional TV, broadcast singal, and common people's TV reception becomes simple and convenient.But no matter how watching of TV programme popularizes the convenient effect of " broadcasting " that also replaced not, at first use the direct broadcasting satellite TV reception to need corresponding necessary condition, satellite receiving equipment, television receiver, and metastable electrical source of power.FM broadcasting is moved reception with it, and receiving terminal is cheap, listens to advantages such as signal is clear; Occupy the position of not replacing, common people can be in the field, wander about the streets between broadcast listening, understand current events; Particularly in the accident generation, damage is built in power breakdown; TV signal receives and does not satisfy the requirements fully, and at this time, it is particularly outstanding that the advantage of FM broadcasting just seems.At the beginning of 2008, involving the freezing calamity that southern number is economized, to 5.12 Wenchuan violent earthquakes, all is to adopt through the broadcast mode guidance to relieve the people in stricken areas, and diffuses information.The pattern of this solution of emergent event is by governments at all levels utilizations with adopt, for the raising of the efficient of stablizing, relieve the people in stricken areas of society plays an important role.

From the product structure and the implementation process of all previous broadcasting and TV project of "Communication with Every Village", mostly FM broadcasting is to adopt with the village is the small-power coverage mode of unit, and single channel or multichannel isotype are arranged.The replace mode of low power transmitter has played good effect for solving the problem that " frontier and poor " regional people televiews, broadcast listening is difficult over a period to come; But this pattern also exists problems; Show that mainly the regular maintenance difficulty is (like the electricity charge; Breakdown Maintenance etc.), cause equipment to use normally for a long time.The logical transmitter in village village is in the state of paralysis basically after several years; And prior art adopts mains-supplied, need be placed in rural area family (needing power supply), needs the manual manual operation switch; The bad management of expense that produces; Do not have the network supervision ability, the transmitter situation can't be understood by administrative department, can not on-call maintenance during device damage.

The utility model content

The utility model provides a kind of any expense that do not produce, and has the network supervision ability, the multichannel FM broadcasting emission system of convenient for maintaining.

Realize the FM broadcasting emission system of the utility model purpose, comprise satellite earth antenna, power splitter, satellite receiver module, rf modulations module, power amplifier module, merit allocation/synthesizer, transmitting antenna, link to each other successively; Also comprise the controller that links to each other with the rf modulations module with said satellite receiver module, the electric power system and the remote communication interface that link to each other with said controller; Said electric power system comprises solar power system and wind power generation system and storage battery.

The multichannel FM broadcasting emission system of the utility model adopts civil power and wind-force, solar energy dual power supply, can lay any old place again; Equipment carries the switching on and shutting down timing device, directly carries out switching on and shutting down during the school via satellite, need not produce any expense; Has the network supervision ability; Administrative department can supervise transmitter state, reports to the police during device damage, and convenient for maintaining personnel keep in repair.

Description of drawings

Fig. 1 is the structural representation of the utility model multichannel FM broadcasting emission system.

Embodiment

As shown in Figure 1, the FM broadcasting emission system of the utility model comprises satellite earth antenna 1, power splitter 2, satellite receiver module 3, rf modulations module 4, power amplifier module 5, merit allocation/synthesizer 6, transmitting antenna 7, links to each other successively; Also comprise the controller 8 that links to each other with rf modulations module 4 with said satellite receiver module 3, the electric power system and the remote communication interface 12 that link to each other with said controller 8; Said electric power system comprises solar power system 9 and wind power generation system 10 and storage battery 11.

The advantage of the multichannel FM broadcasting emission system of the utility model is following:

1, green energy resource: electrical problem is to perplex the realistic problem that geting through broadcast transmission of television equipment in village village is used always, is problem in some regional common people's clothing ,food and housing provisional capital, how to afford the electricity charge of transmitter.This programme utilizes the electrical source of power of the pattern of wind light mutual complementing (solar energy and wind energy) as frequency modulated transmitter, has thoroughly solved the problem of the daily electricity charge, in nothing power supply area the FM broadcasting emission can be provided also simultaneously.Because transmitter has broken away from local unsettled electrical network, has also reduced the rate of breakdown of equipment from another point of view.

2, modular construction: emission system adopts modularized design; Make up front end of emission through different functional, can be according to the concrete condition and the fund state at scene, through the increase and decrease of functional module; Reach and change transmission channel quantity, the purpose of perfect management function.This distributed systems structure for reducing system risk, makes things convenient for system maintenance, has played very big effect.

3, multichannel emission technology: multichannel FM broadcasting front end of emission adopts multifrequency lift-off technology, adopts independently information source reception, modulation, power amplifier, the pattern that power is synthetic.Improved the efficient of frequency modulation programming on structure and on the function widely.

4, prevent intercutting measure: there is its unique politics mission in the broadcasting and TV system, and " anti-intercutting " is the task that broadcasting and TV units at different levels pay special attention to all the year.Particularly to " village village geting through broadcast " such transmitter management, more loose, therefore anti-intercutting just seems more important.Multichannel frequency modulation front end of emission adopts several kinds of technological means, even in line with not broadcasting the principle of also well broadcasting, guarantee the fail safe of broadcasting signal.

5, Intellectualized monitoring: multichannel FM broadcasting front end of emission adopts intelligent monitoring system; Can realize each functional module is monitored in real time; Simultaneously can be according to the preset switching on and shutting down time; Timed power on/off to detected failure condition, sends warning message through mobile communcations system.

6, network management architecture: the logical small-power transmitter in village village all was " fighting separately " in the past, because the shortage of human resources, the reason such as remote of region has caused the blank of supervision.In order to change this present situation, can adopt ripe radio mobile communication technology, make up monitor network, by unit the frequency modulation in institute each village of linchpin is launched centralized monitor, equipment unified management with the county.

Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection range that claims of the utility model confirm.
