Abstract
The utility model is a microphone adapted for video camera positioning and tracing in a conference television system. The microphone is a capacitance type desktop microphone, comprising a base, a neck tube, a sound pickup head, etc. The microphone adapted for video camera positioning and tracing is characterized in that a Z i L O G Z 8 6 E 0 8 control chip and an M An X control processing line chip are embedded in the microphone. The switching signal of the microphone can flexibly and duly control the video camera automatically positioning and tracking the speaker after processed by the chips. The utility model has simple and novel design, favorable effect of the video camera automatic positioning and tracing, avoided sensitively outputting of the noise in a meeting place, and low cost.
Description
Technical field
The utility model is a microphone, the microphone that particularly a kind of Camera Positioning that is used for TV conference system is followed the tracks of.
Background technology
Video conferencing popularizes day by day, TV conference system (video conferencing system) needs to be equipped with the may command video camera, point to the spokesman fixed position by many far-ends of professional's Artificial Control or near end camera, therefore, video conferencing manufacturer has developed the sound tracking camera, according to different spokesman's sound, video camera changes tracking automatically, this mode preferably resolves the problem of automatic tracking location, but there is this system price costliness, the defective that its anti-interference and reliability are relatively poor, and combine complicated with meeting room speech system.The applicant once developed speech microphone/video camera multi-functional conference control system that links, and the mode that promptly adopts microphone to follow the tracks of has solved the problem of automatic tracking location preferably.To the microphone tracking mode, also have Sony Corporation's (No. 97113411.1, Chinese patent) of Japan, the product of the PHLIPHS company of Holland all is microphone/video camera interlock, when opening microphone, Camera Positioning is to microphone position.This mode has solved the location tracking problem of video camera, but this kind equipment establishes one's own system, audio frequency is provided, the video synthesis conference system, but can not accept the control of video conferencing system to video camera, corollary system can not organically combine, in order to solve problem separately, two cover picture pick-up devices need be installed in a meeting-place, and need the professional to control.
Summary of the invention
The purpose of this utility model is a kind of microphone that has with video camera interlock function of design, can be applicable to the Camera Positioning tracking promptly, can also avoid sensitivity to the meeting-place noise, video camera need not Artificial Control to spokesman's shooting tracing process when using in TV conference system, can realize that also the chairman controls spokesman's shooting easily, reduce the equipment cost of video conference, improve video, the audio frequency effect of video conference.
The technical scheme that realizes the present utility model purpose is to adopt existing condenser type desktop microphone, inner installation and control chip (single-chip microcomputer), the FAAME1 that it is characterized in that circuit in the microphone is chairman's control circuit, control data inputs to 10 pin P3.3 of U1 control chip, connect level pull down resistor R109 simultaneously, the 9 pin P3.2 of U1 are connected with 1 pin R0 of U2 control and treatment chip, the 11 pin P0.0 of U1 connect the 4 pin DI of U2, the 9 pin P3.1 of U1 connect the 5V power supply, K switch 10,13 pin P0.2 and the 12 pin P0.1 of U1 are read-write control lines, P0.2 connects the 2 pin RE of U2,3 pin DE, it is the single-chip microcomputer clock circuit that the 6 pin XTAL1 of U1 and 7 pin XTAL2 connect crystal, the 15 pin P2.0 of U1 and 16 pin P2.1 sending and receiving light pipes, it is chip power supply that the 8 pin VCC of U2 connect the 5V power supply, 7 pin B are connected CON1 with 6 pin A be RS485 interface terminals; Control chip adopts the ZiLOGZ86E08 integrated circuit block, and control and treatment circuit chip adopts the MAX485 integrated package.
When being applied to video conferencing, the utility model has tangible advantage.
At first, this microphone is applicable to that the Camera Positioning of video conferencing follows the tracks of, can be in time with spokesman's signal conveys to video camera, be convenient to video camera flexibly, the spokesman is followed the tracks of in the location exactly.
Secondly, the utility model product orientation is accurate, has avoided the responsive output of meeting-place noise.
The 3rd, the chairman can control meeting-place speech order easily and select the spokesman, and control Camera Positioning tracing object.
The 4th, simple in structure, cheap.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is done more detailed explanation.
Accompanying drawing 1 is the microphone outline drawing;
Accompanying drawing 2 is a microphone control circuit schematic diagram.
Fig. 1 has showed a kind of shape of general condenser type desktop microphone, also is the outline drawing of the utility model one embodiment.Establish control switch (4) on pedestal (1) panel, inside is provided with circuit board (this figure does not show), and neck tube (2) is that soft elastic tube connects hard tube, and pick-up head (3) is installed in the front end of neck tube (2).
Accompanying drawing 2 has clearly illustrated the digital control circuit situation of microphone.The embedded control chip of embodiment of the present utility model adopts the Z86E08 of ZiloG company.
The microphone power supply is 5V DC, K10 is the microphone control switch, when microphone cuts out or opens, open or close the signal transmission and enter the P3.1 port, FAAME1 is chairman's control circuit, and control data inputs to 10 pin P3.3 of U1 control chip, connect level pull down resistor R109 simultaneously, the 9 pin P3.2 of U1 are connected with 1 pin R0 of U2 control and treatment chip, and the 11 pin P0.0 of U1 connect the 4 pin DI of U2, and the 9 pin P3.1 of U1 connect the 5V power supply.13 pin P0.2 and the 12 pin P0.1 of K switch 10, U1 are read-write control lines, P0.2 connects 2 pin RE, the 3 pin DE of U2, it is the single-chip microcomputer clock circuit that the 6 pin XTAL1 of U1 and 7 pin XTAL2 connect crystal, the 15 pin P2.0 of U1 and 16 pin P2.1 sending and receiving light pipes, it is chip power supply that the 8 pin VCC of U2 connect the 5V power supply, and 7 pin B are connected CON1 with 6 pin A be RS485 interface terminals.
