First technical problem of the present utility model is solved by following technical scheme:
A kind of telephone recourse device main frame, comprise telephone circuit, first audio frequency amplifier, the described first audio frequency amplifier input links to each other with the telephone circuit output with processor respectively, described modulation module is connected between first audio frequency amplifier and the reflector, and the signal that described modulation module is exported first audio frequency amplifier is modulated on the radio frequency and by reflector and sends.
Second technical problem of the present utility model solved by following technical scheme:
A kind of telephone recourse device link radio receiver, comprise receiver, demodulator and playback circuit, described demodulator is connected between receiver and the playback circuit, described demodulator is with the signal demodulation of receiver output and export to playback circuit, and the signal of described playback circuit after with demodulation plays back.
Second technical problem of the present utility model further solved by following technical scheme:
Described playback circuit comprises second audio frequency amplifier and second loud speaker, and described second audio frequency amplifier is connected between the demodulator and second loud speaker.
Also comprise energy supply control module, described energy supply control module is connected between the receiver and second audio frequency amplifier, and described energy supply control module detects receiver has signal output back just to give the power supply of second audio frequency amplifier.
The beneficial effect that the utility model is compared with the prior art is: telephone recourse device main frame of the present utility model comprises modulation module and reflector, and telephone recourse device link radio receiver of the present utility model comprises receiver, demodulator and playback circuit; When the user when telephone recourse device main frame (in 60 meters) far away, platform service center or predefined called sound can play back by the link radio receiver.This has just solved in case of emergency, user and telephone recourse device main frame be not when same room, from platform service center that the telephone recourse device transmits or the problem that can not clearly be heard of predefined called voice signal, thereby guaranteed the exploitativeness of salvaging, salvaging is more successfully carried out.Guaranteed that better the user can obtain relief promptly and accurately, improved Success in Salvage rate and efficient, reduced the relief cost.
Telephone recourse device link radio receiver of the present utility model, be provided with energy supply control module, this energy supply control module detects receiver has signal output back just to give the power supply of second audio frequency amplifier, link radio receiver electric consumption had too much reached purpose of power saving when this was avoided not having signal at ordinary times.
Description of drawings
Fig. 1 is the structural representation of the telephone recourse device main frame of the utility model embodiment;
Fig. 2 is the structural representation of the link radio receiver of the utility model embodiment.
Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further details below by embodiment.As shown in Figure 1, telephone recourse device main frame described in the utility model comprises telephone circuit 50, first audio frequency amplifier 41, modulation module 11 and reflector 12.
Described first audio frequency amplifier, 41 inputs link to each other with telephone circuit 50 outputs.Described reflector 12 inputs link to each other with modulation module 11, and described reflector 12 outputs are connected to antenna 80, and described telephone circuit 50 links to each other with communication network by telephone wire 81.
Described modulation module 11 is connected between first audio frequency amplifier 41 and the reflector 12, and described modulation module 11 is modulated to the signal of first audio frequency amplifier, 41 outputs on (FM) radiofrequency signal, and is sent through antenna 80 by reflector 12.
Above-mentioned telephone recourse device main frame also can comprise loud speaker, and the input of described loud speaker links to each other with first audio frequency amplifier, 41 outputs, and this moment, telephone recourse device main frame also had the broadcast voice functions.Described telephone circuit 50 can comprise telecommunication circuit.
As shown in Figure 2, a kind of telephone recourse device link radio receiver comprises receiver 3, demodulator 2 and playback circuit 1.Described receiver 3 inputs are connected to antenna 82, and described demodulator 2 is connected between receiver 3 and the playback circuit 1, and described demodulator 2 is with the signal demodulation of receiver output and export to playback circuit 1, and described playback circuit 1 plays back the signal after the demodulation.
Described playback circuit 1 comprises second audio frequency amplifier 11 and second loud speaker 12, and described second audio frequency amplifier 11 is connected between the demodulator 2 and second loud speaker 12.
