Description

A kind of equipment that uses bluetooth to carry out transfer of data

Technical field

The utility model relates to a kind of equipment that uses bluetooth to carry out transfer of data, relates in particular to a kind of bluetooth interview machine.Belong to the Bluetooth communication application.

Background technology

The reporter often uses the interview machine or uses wireless microphone when interviewing, run into following problem through regular meeting when these equipment of use:

To the reporter:

(1) interview before, when the interviewer is a lot, use interview machine or recording pen, be difficult to be extruded at one's side by the interviewee.

(2) interview, wireless microphone sometimes with near electronic equipment or other microphone frequency conflicts, destroy recording effect; And can be subjected to the yoke of holding wire when using wire microphone.

(3) interview after, can repeat above problem again when changing the interviewee.

To the interviewee:

(1) a lot of reporters disobey and can make the nervous or expiratory dyspnea of interviewee at one's side.

(2), when the stranger is close, have potential safety hazard for shielded interviewee.

To the organizer:

Can cause the scene disorder, be unfavorable for carrying out normal propaganda activity.

Along with the fast development of Bluetooth technology, bluetooth module is upgraded to Class3 from Class1 in addition, and transmission range and transmission speed are greatly enhanced, and realizes that with bluetooth module the spot coverage transfer of data becomes possibility.

Summary of the invention

The technical problems to be solved in the utility model just provides a kind of interview equipment that uses bluetooth to carry out transfer of data.

A kind of interview equipment that uses bluetooth to carry out transfer of data of the utility model comprises: a plurality of handsets and a main frame.

Above-mentioned handset comprises: audio collection module, A/D modular converter, Bluetooth transmission module, power supply, other external interfaces;

For realizing the collection in worksite of video, above-mentioned handset also can comprise video acquisition module;

Above-mentioned audio collection module is a microphone; Above-mentioned video acquisition module is a camera;

Above-mentioned main frame comprises Bluetooth transmission module, data memory module, D/A modular converter, monitors module, monitor module, data download module, power supply;

Interconnect by bluetooth module between above-mentioned handset and the main frame.

Main frame in above-mentioned a set of equipment adopts identical frequency hopping agreement with handset, main frame can be discerned mutually with the handset that belongs to it, can not discern other handset so main frame and handset between can directly adopt distance control to automatically switch, when having only an estrade machine to be in coverage, main frame links to each other with this estrade machine automatically.When a plurality of handsets were in coverage simultaneously, the main frame user can manually select in selected main frame, also can import the handset numbering at input window and select.

The utility model has following beneficial effect:

1, because the intrinsic frequency hopping of bluetooth utilizes the utility model, have anti-interference, anti-with frequently spying on anti-scanning;

2, because Bluetooth technology is based on the transmission of digital signal, can carry out encrypted transmission between the paired device;

3, the utility model volume is little, and is low in energy consumption.

Embodiment

Below in conjunction with drawings and the specific embodiments the utility model is elaborated.

The utility model is a kind of to use interview equipment that bluetooth carries out transfer of data as shown in Figure 1, 2, and chief component comprises many estrades machine 1 and a main frame 8.

Wherein said handset comprises: audio collection module 2, A/D modular converter 3, Bluetooth transmission module 4, power supply 5, other external interfaces 6;

For realizing the collection in worksite of video, described handset 1 also can comprise video acquisition module 7;

Described audio collection module 3 is a microphone; Described video acquisition module 7 is a camera, as shown in Figure 3;

Described main frame 8 comprises Bluetooth transmission module 9, data memory module 10, D/A modular converter 11, monitors module 12, monitor module 13, data download module 14, power supply 15;

Interconnect by bluetooth module between described handset and the main frame.

The main frame of a set of equipment and handset adopt identical frequency hopping agreement, and main frame can be discerned mutually with the handset that belongs to it, can not discern other handset so main frame and handset between can directly adopt distance control to automatically switch.

In use, at first open the mains switch 16 of main frame and handset, shown in Fig. 4,5, can show its electric weight situation on the handset panel electric-quantity display device 18.Main frame and handset be search mutually, finds apart from its nearest corollary equipment and interconnects, and at this moment the signal strength display on main frame and the handset 17 can show the signal strength signal intensity between the paired device that connects.When having only an estrade machine to be in coverage, main frame links to each other with this estrade machine automatically.

When a plurality of handsets were in coverage simultaneously, the main frame user can see the nearest 3 estrade machines in coverage in selected handset numbering device 19, manually select by button.Also can press selector button 20, input handset numbering is forced selection in connecting handset numbering device 21.

When main frame with after handset normally is communicated with, main frame can receive the signal of handset, stores and monitors.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only own for specific embodiment of the utility model; be not limited to the utility model; all within claim of the present utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
