Further, described memory is provided with key storage card, the modulus of described digital speech processing module/be provided with speech compression module between D/A converting circuit and decoder.
Further, described detecting unit is connected with judging unit, described judging unit for judge the CF signal detected on channel destination address whether with the addresses match of self audio frequency and video frequency receivers, when mating, by central control unit sending controling instruction to control unit, according to control command, control to open audio and video receiver.
The beneficial effects of the utility model: it is large that the utility model provides a kind of transmitting power, can the different common frequency band of unrestricted choice as required, and emergency can send help signal, and effectively can reduce the digital handset of intercom power consumption speed.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the system block diagram of the digital handset according to the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
As shown in Figure 1, a kind of digital handset according to embodiment of the present utility model, comprises housing, is provided with audio frequency and video frequency receivers in described housing, codec, central control unit, high-gain aerial, input through keyboard module, display module, digital speech processing module, memory and electric supply installation, described digital speech processing mould comprises modulus/D/A converting circuit, voice transmitting-receiving circuit, loud speaker and microphone, described audio frequency and video frequency receivers is connected with central control unit by codec, described audio frequency and video frequency receivers, input through keyboard module, display module, memory and electric supply installation are all connected with central control unit, described audio frequency and video frequency receivers is provided with detecting unit and control unit, described detecting unit detects on receive channel whether have CF signal, when CF signal having been detected, controlled to open audio frequency and video frequency receivers by described control unit, be provided with filtration module between described high-gain aerial and audio frequency and video frequency receivers, described central control unit is also connected with GPS locating module.
In a specific embodiment, described memory is provided with key storage card, the modulus of described digital speech processing module/be provided with speech compression module between D/A converting circuit and decoder.
In a specific embodiment, described detecting unit is connected with judging unit, described judging unit for judge the CF signal detected on channel destination address whether with the addresses match of self audio frequency and video frequency receivers, when mating, by central control unit sending controling instruction to control unit, according to control command, control to open audio and video receiver.
Conveniently understand technique scheme of the present utility model, below by way of in concrete occupation mode, technique scheme of the present utility model is described in detail.
When specifically using, audio frequency and video frequency receivers is also provided with judging unit, this judging unit connects detecting unit, the destination address that this judging unit judges the CF signal detected on channel by detecting unit whether with the addresses match of self audio frequency and video frequency receivers, if when judging that acquisition matches, by central control unit sending controling instruction to control unit, according to this control command, control to open audio frequency and video frequency receivers and receive; When the destination address that judging unit judges to obtain the CF signal detected by detecting unit is not mated with the address of self audio frequency and video frequency receivers, central control unit sending controling instruction, to control unit, controls this audio frequency and video frequency receivers and is in closed condition.Thus can effectively when detecting unit does not detect CF signal, control makes audio frequency and video frequency receivers be in closed condition, effectively saves power consumption, and detecting unit detect channel has CF signal time, notice control unit is opened audio frequency and video and is received, and makes to be in accepting state; Meanwhile, because whether judging unit can, according to the destination address of the CF signal on channel, judge whether consistent with the address of this audio frequency and video frequency receivers, thus effectively avoid the phenomenon that receives by mistake, or when address does not match, fault open audio frequency and video frequency receivers, makes to waste power consumption.
Signal reception processing procedure: through high-gain aerial by audio frequency and video frequency receivers received RF signal, high-gain aerial can realize the diffracting power of vision signal and higher receiving sensitivity, to this radiofrequency signal through filtration module elimination garbage, control utilize codec to encode to this signal and be stored in memory through central control unit again, use the key storage card in memory can be encrypted this signal, the ciphered data information mated with the machine is extracted according to signaling, then this ciphered data information is carried out decompress(ion) by speech compression module, decoded by codec again, produce PCM signal, decoded PCM signal is carried out D/A conversion by modulus D/A converting circuit, played back by loud speaker through voice transmitting-receiving circuit.
Signal launches processing procedure: modulus D/A converting circuit carries out A/D sampling to the analog voice signal received through voice transmitting-receiving circuit by microphone, change into corresponding PCM signal, PCM signal is delivered to speech compression module and carries out compress-encrypt, encode through codec again, produce data-signal, be sent to central control unit to store, and sent by gain antenna through filtration module.Locating for GPS is then control transmitting emergency help signal button by being provided with in input through keyboard module, when needs flash appeal, by putting through emergency button, being positioned, help it by control GPS locating module to current user position.
In sum, by means of technique scheme of the present utility model, it is large that the utility model provides a kind of transmitting power, can the different common frequency band of unrestricted choice as required, emergency can send help signal, and effectively can reduce the digital handset of intercom power consumption speed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
