Abstract
The utility model disclosed a digital camera with film recording on a hard disk, providing a hard disk interface and a hard disk on the prior digital camera which includes a camera, a camera cloud platform, three variable lens, a microphone, an image signal collecting circuit, an audio signal collecting circuit, a video and audio compressing circuit, a central processor and a TCP/TP Ethernet interface. One end of the hard disk interface is jointed with the hard disk, and the other end is connected with the central processor. The monitoring picture of the utility model will be preserved on the hard disk completely, no matter whether the network between the digital camera and the monitoring center is locked. The monitoring centre can move out the monitoring image data momentarily from the hard disk by the Ethernet.
Description
Technical field
The utility model relates to digital camera.
Background technology
In industry, traffic, commercial, finance, in the field modern managements such as Lou Yu, the normal digital camera of band TCP/IP Ethernet interface that adopts carries out Monitoring and Controlling, this video camera comprises camera, the The Cloud Terrace of camera, three variable lenses, microphone, the picture intelligence Acquisition Circuit, the audio signal sample circuit, look the audio compression circuit, central processing unit (CPU) and TCP/IP Ethernet interface, the simulated audio signal of the analog video signal of camera output and microphone output is looked the audio compression circuit through the picture intelligence Acquisition Circuit with input after the audio signal sample circuit conversion becomes digital video signal and digital audio and video signals respectively, by looking the audio compression circuit to image, voice signal carries out in real time compression synchronously, packing, be defeated by central processing unit after the multiplexing process, central processing unit by coupled TCP/IP Ethernet interface with data delivery to outer computer and relevant device, and accept the outside control signal of issuing, the The Cloud Terrace of control camera rotates, three variable lens focus adjustment etc.This digital camera weak point in actual use is the problem that exists picture record to lose, digital camera board number in supervisory control system more for a long time, the transmission load of Ethernet is with saturated, the collision frequency showed increased, cause real-time image transmission difficulty, the pictorial data of control point is lost, and lose meaning of monitoring.When ethernet line breaks down, to lose as communication media interruption or switch, the computer pictorial data that all can cause the control point that breaks down, this is definitely unallowed in many important supervisory control systems.
Summary of the invention
The purpose of this utility model is to lose problem for the picture record that overcomes digital camera, and a kind of digital camera with the hard disk video is provided.
The digital camera of band hard disk of the present utility model video is existingly to comprise camera, camera The Cloud Terrace, three variable lenses, microphone, picture intelligence Acquisition Circuit, audio signal sample circuit, looking in the digital camera of audio compression circuit, central processing unit and TCP/IP Ethernet interface hard-disk interface and hard disk are set, one termination hard disk of hard-disk interface, the other end links to each other with central processing unit.
During work, the every obedient pictorial data that central processing unit absorbs by hard-disk interface, deposits hard disk successively in and preserves, and generally can preserve 15 days pictorial data.After hard disk is write and expired, whenever write the new pictorial data of a card again, just obedient data are the earliest washed out, successively circulation.Be kept at the pictorial data on the hard disk, by hard-disk interface, take out successively,, deliver to the equipment such as host computer of Surveillance center again by TCP/IP interface and network by central processing unit.
No matter whether the network of the utility model data video camera and Surveillance center was unimpeded at that time, monitor that image is not kept at a card on the video camera hard disk with not leaking.Surveillance center by Ethernet, accesses the watch circle image data at any time from the hard disk of this digital camera.
Description of drawings
Fig. 1 is that the utility model constitutes block diagram;
Fig. 2 is a kind of physical circuit figure of extension in the utility model.
Embodiment
With reference to Fig. 1, the digital camera of band hard disk of the present utility model video is existingly to comprise camera 1, camera The Cloud Terrace 2, three variable lenses 3, microphone 4, picture intelligence Acquisition Circuit 5, audio signal sample circuit 6, looking in the digital camera of audio compression circuit 7, central processing unit 8 and TCP/IP Ethernet interface 9 hard-disk interface 10 and hard disk 11 are set, one termination hard disk 11 of hard-disk interface 10, the other end links to each other with central processing unit 8.
Hard-disk interface can adopt USB interface or EIDE interface or ide interface or ata interface or scsi interface or IEEE1394 interface or Serial ata interface or FC-AL interface.
Fig. 2 is the circuit diagram of the newly-increased part of the utility model, in the illustrated example, hard-disk interface 10 adopts USB interface, hard disk 11 is the hard disk of band USB interface, central processing unit 8 is TMS320VC5402 chips, and the WR of usb interface controller, RD, AO, CS, DRQ, DACK, D0～D7 pin is corresponding with the respective pins of TMS320VC5402 links to each other.
