Illegal signal reception antenna is connected with high frequency signal amplifier electricity, and this high frequency signal amplifier is connected with the harmonious demodulator of signal electricity, and the harmonious demodulator of this signal is connected with sound compressor circuit and signal high -speed sampling ware electricity respectively, and this sound compressor circuit and signal high -speed sampling ware are connected with network interface circuit module electricity respectively, GPS or beidou module and network interface module electric connection. The advantage is novel structure, has utilized the technological means of GPS or the timing of big dipper satellite, adopts many covers the utility model discloses the broadcast singal of fast acquisition pirate radio transmission simultaneously to monitoring data utilization network transport to the monitoring center, this kind of positioner compares with traditional monitoring vehicle, has that convenient to use, running cost are low, an easy to maintain, advantage that locating speed is fast.
Description
Technical field
This utility model relates to broadcast television signal monitoring field, is a kind of device for monitoring illegal f-m broadcast station, it is possible to be used in broadcast television monitoring system.
Background technology
In the last few years, all parts of the country occur in that a lot of unauthorized illegal FM radio station, and have become the important means that some lawless persons obtain unlawful advantage.Original radio and television are the carriers that Party and government carry out propaganda work, but pirate radio is but masquerading as some country's main flow broadcast mediums, is engaged in the illegal publicity such as false advertisement of drugs, content is vulgar, have a strong impact on the public credibility of mass media of Party and government, upset normal broadcast and televise order.More seriously, part pirate radio usually can be play and relate to yellow content related to sex.Even also have hostile force to utilize black appliances platform means, carry out reaction publicity, supertition publicity, rumour distribution, cause great social danger, destroy the stable and united of country, there is serious social harm.China's regulation is expressly provided: any radio and television station ratifying without Wen Guangxin office above county level to set up, and broadly falling into " the black appliances platform " illegally set up, once find, all should be banned in accordance with the law.
Pirate radio arranges extremely hidden, is generally all erected in skyscraper.Conceal between standing in great numbers in residential block and high building, greatly improve the disguise of equipment.What have also can take special camouflage, even can take other technological means, places obstacles for radio monitoring, location, to escape strike, in supervision, it is positioned and bans a lot of difficulty of increase.
The means at present pirate radio location taked are that monitoring car sets out first to carry out bigness scale, namely utilize monitoring car in the radio signal strength of different location measurement pirate radio and direction substantially, approach gradually to source location.May finally tentatively find the residential block at pirate radio place, then carefully investigate with artificial hand-held monitoring machine walking again and just can find illegal transmitter.The relatively time-consuming effort of this process, the most smoothly in situation, it is also desirable within several hours, just can find a pirate radio.
Summary of the invention
This utility model provides a kind of monitoring device that illegal broadcasting station is quickly positioned, to solve the problem that original fixed pirate radio monitoring equipment can only find pirate radio and can not directly determine its position.
The technical scheme that this utility model is taked: illegal signals reception antenna electrically connects with high-frequency signal amplifier, this high-frequency signal amplifier electrically connects with signal tuning demodulator, this signal tuning demodulator electrically connects with sound compression circuit and signal high-speed sampler respectively, and this sound compression circuit and signal high-speed sampler electrically connect with network interface circuit module respectively；GPS or Big Dipper module electrically connect with Network Interface Module.
The utility model has the advantages that novel structure, use technological means when GPS or big-dipper satellite school, adopt many set this utility model energy broadcast singals that Quick Acquisition pirate radio is launched simultaneously, and utilize network to be sent to monitoring center Monitoring Data, just can show the position at pirate radio place on the software of monitoring center, in the work of location pirate radio, this positioner compared with traditional monitoring car, have easy to use, operating cost is low, be easily maintained, advantage that locating speed is fast.

Detailed description of the invention
Illegal signals reception antenna 1 electrically connects with high-frequency signal amplifier 2, this high-frequency signal amplifier 2 electrically connects with signal tuning demodulator 3, this signal tuning demodulator 3 electrically connects with sound compression circuit 4 and signal high-speed sampler 5 respectively, and this sound compression circuit 4 and signal high-speed sampler 5 electrically connect with network interface circuit module 7 respectively；GPS or Big Dipper module 6 electrically connect with Network Interface Module 7.
Operation principle
Illegal signals reception antenna 1 receives the signal of pirate radio, then by high-frequency signal amplifier 2, signal is amplified, signal after amplification is demodulated by signal tuning demodulator 3, the solution harmonic obtained carries out A/D conversion by signal high-speed sampler 5, carry out programme content compression also by sound compression circuit 4 simultaneously, when whole device utilizes GPS or Big Dipper module to carry out accurate school, and the data after A/D conversion and sound compression signal are sent to the computer of monitoring center's system by network interface circuit module 7.
This utility model is a kind of remote signal harvester with network interface, self it is not analyzed calculating, it must use with the system support of illegal broadcasting station monitoring center, whole system utilizes net connection together, more than three this monitoring devices must be installed in multiple different locations, just can possess the function of position monitor.
