Abstract
The utility model relates to a network camera which can realize a bidirectional talking function by the internet; the utility model is characterized in that the network camera comprises a network interface and a network audio codec that comprises a network module, a central processing system, an audio codec circuit, a register, an audio output interface, an audio collecting module, an audio input interface, a microphone and a power; the network interface is connected with the network module that is connected with the central processing system; the central processing system is connected with the register that is connected with the audio codec circuit; the audio codec circuit is respectively connected with the audio output interface and the audio collecting module that is connected with the audio input interface; the network audio codec and the circuit in the camera share the power. The network camera has the advantages that: 1. The audio in a CAMER monitoring field can be monitored in real time, which is not restricted in the video monitoring. 2. The audio at the PC end can be transmitted to the CAERMA end and is released by a loudspeaker, and the remote bidirectional talking effect can be achieved.
Description
Technical field
The utility model relates to electronic monitoring and control system, relates in particular to a kind of audio encoding and decoding technique that adopts and passes through the web camera that the internet network can be realized the two-way call function.
Background technology
Along with safety defense monitoring system video camera and development of technologies, the security protection range of application is extensive day by day, and the security protection application is deep day by day, and the trend of security and guard technology development mainly shows as: 1, digitlization, networking, intellectuality, integrated be direction; 2, progressively establish and improve the security protection system of scientific and technical innovation; 3, greatly develop 4C technology (communication/computer/control/multimedia display technology), intelligent building 5A system and intelligence transportation ITS system; 4, network technology and multiple security and guard technology are implemented integrated research and development; 5, create and improve comprehensive safety service network at different levels.Social security Dynamic Monitoring System, city pre-alarming system and safety urban construction are the new opportunities of domestic security protection industry.But nowadays video camera market segment absence of audio transmits the video camera product of (video transmission is only arranged).
Summary of the invention
The utility model is in order to remedy the defective that prior art exists, and the utility model provides a kind of web camera of realizing the two-way call function.
The technical scheme that the utility model is taked to achieve these goals is: a kind of web camera of realizing the two-way call function, comprise video camera and place the interior circuit of video camera, it is characterized in that, also comprise network interface, the network audio codec, described network audio codec comprises mixed-media network modules mixed-media, central processing system, the audio coding decoding circuit, buffer, audio output interface, the audio collection module, audio input interface, microphone, power supply, described network interface is connected with mixed-media network modules mixed-media, described mixed-media network modules mixed-media is connected with central processing system, described central processing system is connected with buffer, described buffer is connected with the audio coding decoding circuit, described audio coding decoding circuit is connected with audio output interface and audio collection module respectively, described audio collection module is connected with audio input interface, described network audio codec and the shared power supply of shooting self-contained circuit.
The utlity model has following beneficial effect:
1. but real-time listening CAMERA monitors on-the-spot audio frequency, and is not limited only to video monitoring.
2. PC can be held audio frequency to be sent to the CAERMA end and discharge, reach the effect of long-range two-way call by loud speaker.
Description of drawings
Fig. 1 is the utility model circuit connection diagram and as Figure of abstract.
Embodiment
Audio input interface and the audio collection module continuous acquisition audio-source of video camera end by being connected with microphone, (AT2042/MSM7578) encodes audio-source by coding/decoding module, we adopt coded system G.711, transfer to central processing unit (CPU/S3C2800) behind the coding and handle the back, can receive live audio in real time by associated software at the PC of access network end by mixed-media network modules mixed-media (ETHERNET/RTL8100CL) input INTERNET network; Conversely, gather audio frequency at the PC end by Mike, the PC end is that codified is sent to network, discharges by the loud speaker that is connected with audio output interface after the encoding and decoding of video camera end, reach the function of two way audio conversation, the model of above-mentioned buffer is (K4S283233).
