Abstract
The utility model discloses a wireless broadcast real time monitor which includes an FM/AM demodulation and field intensity detection circuit, an audio frequency ADC, an MCU processor, a DSP, and a GPRS module. The FM/AM demodulation and field intensity detection circuit is connected with a wireless receiving antenna. The GPRS module is connected with a wireless transmitting antenna. The wireless broadcast real time monitor can wirelessly transmit a broadcast voice signal to a data center in real time via the GPRS to carry out the real time voice and field intensity monitoring.
Description
Technical field
The utility model relates to the radio broadcasting field, is specially a kind of radio broadcasting real-time monitor.
Background technology
In wireless telecommunications, speech data transmits through wireless signal after need compressing again.Data in the prior art after the wideband sound compression can't be transmitted through narrow band signal, cause can't monitoring in real time voice and field intensity in the wireless telecommunications process.
The utility model content
The purpose of the utility model provides a kind of radio broadcasting real-time monitor, can't be through the problem of narrow band signal transmission to solve prior art wideband sound data.
In order to achieve the above object, the technical scheme that the utility model adopted is:
The radio broadcasting real-time monitor includes FM/AM demodulation and field intensity testing circuit, it is characterized in that: have access to the wireless receiving antenna in said FM/AM demodulation and the field intensity testing circuit; Said FM/AM demodulation and field intensity testing circuit output are connected to the two-way output line; One road output line is electrically connected to audio A C, and another road output line is electrically connected to the MCU processor, also comprises DSP; Be integrated with encryption algorithm among the said DSP; The output of said audio A C is electrically connected with the input of DSP, and said DSP is connected with MCU processor both-way communication, and the output of said MCU processor is electrically connected with the input of audio A C; The signal output part of said MCU processor is connected to the GPRS module, and said GPRS module has access to the wireless transmit antenna.
In the utility model, FM/AM demodulation and field intensity testing circuit can be realized fast amplitude modulationfrequency modulation demodulation, amplitude modulationfrequency modulation full frequency band frequency sweep and field intensity monitoring in real time, in the DSP process chip, use encryption algorithm, make the real-time music digital coding be compressed to 8k.And keep extraordinary former audio fruit, to realize can passing through the arrowband wireless device through the row real-time Transmission.The utility model can carry out the monitoring of real-time voice and field intensity with broadcast speech signal through GPRS wireless real-time returned data center.
