Abstract
The utility model discloses a component device for video-audio signal transmission system, which mainly consists of a helmet, a transmission receive device, a microphone and an earphone, wherein the helmet is provided with a camera. A modem in the device is a video-audio dual-purpose modem. The microphone, earphone and antenna of transmission receive device are connected with corresponding interface, respectively. The utility model has the advantages of simple structure, convenient operation, which is suitable for movable operation and solve the problem of realizing the unidirectional transmission of image in real-time and full-duplex of talkback in the way of portable roaming. Thus, the utility model is suitable for all kinds of situations need to track monitor moveably such as electric system, traffic system, security etc.
Description
The utility model belongs to the parts of transmission system, specifically a kind of video/audio communication conveyer of roaming type.
The picture control technology had obtained developing by leaps and bounds in recent years, the application of relaying as live TV is an example, but in a lot of occasions, as scenes such as electric power, traffic, security personnel, construction operations, then need a kind of light device to realize target is carried out mobility tracing and monitoring and on-the-spot report more, so that the monitoring of rear website.Like this, under the situation of obtaining more reflection on-the-spot voice and image information, just may implement more effectively control and command and decision-making disposal.Disclose a kind of duplexing portable communication apparatus in Chinese patent 92105625 application cases, provided the part device that contains transmission, receives, and with its power supply unit between carry out the jockey that tiltable is connected.Also comprise a kind of helmet that is provided with microphone, loud speaker and described device.
The purpose of this utility model is to provide a kind of roaming type audio-visual conveyer, and this device can be used for tracking target, and the unidirectional transmission of image and the full duplex intercommunication function of voice are finished in on-site supervision in real time.
The audio-visual conveyer of roaming type of the present utility model mainly is made up of the helmet, sending and receiving apparatus, microphone, earphone, is provided with modulator-demodulator in the sending and receiving apparatus, it is characterized in that said helmet front upper place is provided with a video camera; Said modulator-demodulator is audio-visual dual-purpose formula modulator-demodulator; The antenna of the microphone that transmission information is used, earphone and sending and receiving apparatus is connected with corresponding interface in the device respectively.
The audio-visual conveyer of roaming type of the present utility model, simple in structure, be convenient to make and installation, safe in utilization.Be located at the video camera on the helmet, its camera is consistent with the human eye direction, situation about can see the scene easily sends to the Surveillance center at rear in time, on-the-spot situation can be carried out scene report by microphone and be exchanged, and this device is applicable to the various occasions that need flow electric power, traffic, security personnel etc. tracing property monitors.
By the following examples and accompanying drawing describe.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural principle schematic diagram of conveyer.
Fig. 3 is the application principle figure of embodiment.
Referring to accompanying drawing.As Fig. 1, the audio-visual conveyer of roaming type of the present utility model mainly is made up of the helmet 1, sending and receiving apparatus 2, microphone 7, earphone 6, is provided with modulator-demodulator in the sending and receiving apparatus, it is characterized in that said helmet front upper place is provided with a video camera, camera is installed in helmet front upper place.Said modulator-demodulator adopts the audio-visual dual-purpose formula modulator-demodulator of outsourcing, is used for the modulation of vision signal and audio signal.This example adopts the audio-visual modulator-demodulator of phase-locked loop, and the entire circuit device is located in the helmet.Certainly it also can use the version of separate type.Earphone 6 is installed in the both sides of the helmet, and microphone 7 can be connected with the earphone outside left, is used for carrying out voice contact with monitoring central station, and the antenna 4 that sending and receiving apparatus connects is located at the top of the helmet, and they are connected with corresponding interface respectively.Video camera 3 in the present embodiment adopts superminiature pin electronic shutter colour TV camera.High sensitivity microphone and loading formula theaomni-directional transmission and reception antenna have been adopted simultaneously.The 5th, the metal mounting panel, it prevents that except being used as radiation with the protection head, also will be fixed in the helmet with the sending and receiving apparatus of the audio-visual modulator-demodulator of phase-locked loop with it.
Shown in Figure 2, be provided with video interface a, antennal interface b, power interface c, d and voice transfer interface e, f, g in the sending and receiving apparatus 2, wherein antenna 5 is received the modulator-demodulator of sending and receiving apparatus by antennal interface b, and video camera 2 is attached thereto by video interface a; Ag, Af termination earphone, Ae termination microphone, microphone signal inserts from voice transfer interface e, and earphone signal then inserts from f, g interface; Be connected with the 12V DC power supply on power interface c, the d, it provides working power for the entire circuit device.
The application principle figure of Fig. 3 has represented setting and the working condition between audio-visual conveyer of roaming type of the present utility model and the monitoring central station.The left side is this device, and the image information Vo that comes from camera sends its vision signal by antenna T (being the antenna 4 Fig. 1, Fig. 2) after modulating.Microphone signal also sends by antenna T by the audio signal Ao of modulation simultaneously; Instruction voice audio signals A1 from monitoring central station is received and through demodulation voice restoration is delivered to earphone and listen to by antenna T equally; The right be a monitoring central station, and it is provided with monitor and audio amplifier, is used for showing and plays voice messaging from the image of the vision signal V1 of antenna T1 reception and live audio signal Ao, that obtain after demodulation.The audio signal A1 that sends to this device carries out from independent antenna T2.This device is in 300 meters scopes, and is respond well.
The concrete course of work is carried out in following mode: the superminiature pin colour TV camera of selecting for use in the embodiment device 3, and high sensitivity microphone 7, the image and the sound of environment of living in are gathered in real time, the sound that collects, image input are carried out hyperfrequency (the above microwave of 1G) modulation by the audio-visual modulator-demodulator of phase-locked loop of CPU control, become carrier signal and carry out wireless transmission through loading formula theaomni-directional transmission and reception antenna T.Radiofrequency signal is received by the isotropic receiving antenna T1 of monitoring central station and enters audio-visual modulator-demodulator main frame, through demodulation, audio-video signal is restored and output to play in the display of Surveillance center and show.The instruction voice signal that monitoring central station is sent carries out frequency modulation (FM) modulation through audio-visual modulator-demodulator main frame, sends by omnidirectional transmitter antenna T2.Realized receiving by loading formula theaomni-directional transmission and reception antenna T in the device of receiving terminal, the audio signal that receives enters the audio-visual modulator-demodulator of phase-locked loop and carries out demodulation, and earphone 6 is arrived in voice output.
