Abstract
Noiseless team transceiver machine is that one is applied in the place such as museum, tourist attraction, is supplied to the explanation equipment that team visitor visits use.All-in-one is inner primarily of ARM microprocessing unit, signal transmitter unit, signal receiving unit, Power supply unit, audio signal reception processing unit, audio signal demodulating unit, D/A converting unit and connecting circuit thereof composition, and all-in-one outside has charge port, display screen, MIC/ earphone jack, button.This equipment some can form noiseless team intercom system, and it is by the sending and receiving function by key control, switching device.The system of composition can be arranged to different frequency range, for different team simultaneously, do not interfere with each other, meanwhile, between each team guide and visitor, can also two-way exchange speech be carried out.
Description
Technical field
The utility model relates to and is a kind ofly suitable for the wireless explanation equipment that team visitor visits use, particularly a kind of noiseless team transceiver machine.
Background technology
Along with the fast development of cultural tour industry, increasing people select tourism to visit as a kind of approach enlarged one's knowledge, in our allegro living environment, in order to more sight spot can be visited, most visitor can select with a visit, the trouble of planning road is not only eliminated with a visit, but also the characteristic that guide directly visits certain sight spot can be followed, like this, guide is just needed to roll into a ball as visitor provides better service, wherein the most important thing is to visitor's transmission of information and explanation aspect, most of guide is with group or adopts megaphone to carry out transmission of information, the weak point of this mode is a riot of sound, coverage is little, mutual interference, and also obstacle is had for the interchange between visitor and guide, like this, just need one can carry out two-way exchange speech clearly, and glitch-free wireless explanation system between team.
Summary of the invention
In order to solve the demand, the utility model has designed and developed a kind of equipment that can carry out the explanation of noiseless team, this equipment integrates explanation, listens to, by by key control switching working mode, utilize advanced wireless transmit-receive technology, carry out two-way exchanges and dialogues, guide can be shown better exchange with the On-the-spot Interaction between visitor, and multiple channel can be arranged to, and not interfere with each other between channel, be particularly suitable for team's tourism and use.
The technical solution of the utility model is achieved in that
1) a kind of noiseless team transceiver machine, by external shell, internal control unit and connecting circuit composition thereof, internal control unit and connecting circuit thereof comprise ARM microprocessing unit, signal transmitter unit, signal receiving unit, Power supply unit, audio signal reception processing unit, audio signal demodulating unit, D/A converting unit forms, external shell has charge port, display screen, MIC/ earphone jack, button, by by the signal transmitter unit in key control all-in-one and signal receiving unit, when opening emission function, microphone input speech signal is carried out by MIC jack, again by audio signal reception processing unit, after the process of ARM microprocessing unit, be converted into radiofrequency signal to be launched by signal transmitter unit, and when opening receiving function, signal receiving unit received RF signal, after being undertaken processing by ARM microprocessing unit, audio signal demodulating unit, D/A converting unit, transforming, transferring audio signal transmission to earphone jack plays, during by key control transmission-receiving function, display screen shows its operating state.
2) the Power supply unit of transceiver machine is chargeable lithium cell, reusable, environmental protection.
3) button of transceiver machine comprises volume add-substract key, frequency range add-substract key, power key and function key, function key can a key control, switch the sending and receiving function of all-in-one, convenient and swift.
4) earphone of transceiver machine, Mike's jack are same jack.
Compared with prior art, its advantage is the design of this utility model:
1) the advanced wireless transmit-receive technology of this equipment utilization, and transmitting, reception technique are integrated in the housing of a compact.
2) this equipment operating is simple, is controlled, switches, realize the conversion of energy of sending and receiving merit by a function key.
3) this transceiver transmitter can be with multiple stage transceiver receiver, is applicable to different scales team and uses.
4) this transceiver machine can receive 128 groups of different channels, and when multiple team uses different channel simultaneously, does not interfere with each other.
5) this transceiver machine connects use, handled easily by the special one earphone of earphone Mike.
6) the Power supply unit of the transceiver machine in system adopts light, the capacious chargeable lithium cell of quality to power, and enables long-time use.
This utility model is skillfully constructed, be an equipment transmitting set and wireless terminal receiver design, switch to change by a key and receive, send out function, the number that can arrange transmitting and receiving according to the number of team meets the demand of team, and the communication can carried out between visitor and guide, carry out two-way exchange speech, solve over the traditional mode only listening guide interpreting, add interactive function, the system simultaneously formed can be arranged to nearly 128 channels, and do not interfere with each other, ensure that multiple team impregnable effect when visiting, for visitor visits the service providing hommization more.
Accompanying drawing explanation
Fig. 1 is transceiver machine stereogram.
Fig. 2 is transceiver machine theory diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described:
According to Fig. 1, this transceiver machine by external shell 1, display screen 2, frequency range subtracts key 3, frequency range adds key 4, volume adds key 5, volume down key 6, power key 7, function key 8, MIC/ earphone jack 9, charge port 10 form.
According to Fig. 2, this transceiver machine ARM microprocessing unit, signal transmitter unit, signal receiving unit, Power supply unit, audio signal reception processing unit, audio signal demodulating unit, D/A converting unit form.
When tourist guide leads team visitor to visit, tourist guide and visitor everyone wear a transceiver machine, what tourist guide used is set to transmitter, what visitor used is configured to receive machine, so just constitute noiseless team intercom system, now, by power key 7, after transmitter is opened by tourist guide, visitor opens receiver, the tourist guide of same team and visitor add key 4 and frequency range by frequency range and subtract key 3 and carry out frequency range adjustment, be arranged to same channel, tourist guide is explained by earphone Mike one earphone special, sound is input to audio signal reception processing unit by MIC jack and connecting circuit thereof, in ARM microprocessing unit, after treatment, transmitted by signal transmitter unit, and the signal that the signal receiving unit receiver/transmitter of visitor's transceiver receiver is launched, again by ARM microprocessing unit, audio signal demodulating unit, the process of D/A converting unit, after conversion, by earphone output, sound is play.
Certainly, if some visitors think and conduct a sightseeing tour or other visitors carry out interaction time, carry out regulatory function by function button 8, be adjusted to the function of transmitting, put question to, operation principle is described above.
Light by quality, the capacious chargeable lithium cell of whole Circuits System of noiseless team transceiver machine is by connecting circuit continued power, if electricity is not enough, can be charged by charge port 10, the size of volume then can add key 5 by volume and volume down key 6 regulates.Meanwhile, screen display information about power, frequency range information, information volume is shown.
In same place, multiple team is when jointly visiting, frequency range can be arranged to 128 groups of different channels, after team's fixed channel that each tourist guide leads, then can not be subject to the interference of other team, can not there is confusion in the management of team, be applicable to very much the use of the places for sightseeing such as scenic spot.
