Description

A kind of multichannel usb data high speed acquisition workstation

Technical field

The utility model relates to a kind of acquisition workstation, particularly the concurrent acquisition workstation of a kind of multichannel usb data high speed.

Background technology

The acquisition workstation in a local police station, need process multi-section law-enforcing recorder to carry out data upload, if allow registering instrument upload singly, obviously upper transfer efficiency is too low, once the electronic evidence in law-enforcing recorder can not be uploaded in time, law enfrocement official carries out task on duty fast and will be obstructed; If allow multi-section registering instrument upload electronic evidence simultaneously, when registering instrument especially more than 16 USB port is uploaded, because mainboard carrying maximum drive current is limited, mainboard is gently then made normally not work by activation record instrument, or uploading speed is too low, or software cannot normally run; Heavy then cause deadlock, the collapse of system blue screen etc.

The mainstream technology of current this problem of solution adopts usb2.0 hub scheme, namely be exported by the USB input interface expansion multichannel USB of on mainboard, registering instrument is linked in main frame by multichannel USB, USB2.0 transmission speed 60MB/s in theory, if expand 5 USB port, then the upload thresholds speed of average each registering instrument is 12MB/s, actual uploading speed also can be subject to the restriction of magnetic disc i/o read or write speed, and actual uploading speed is difficult to meet the needs that current mechanism efficiently imports Large Volume Data.

In view of this, be necessary to provide a kind of multichannel usb data high speed concurrent acquisition workstation, to meet practical application needs.

Summary of the invention

The purpose of this utility model is: provide a kind of multichannel usb data high speed acquisition workstation, this acquisition workstation is divided bandwidth equally for usb2.0 hub scheme and be there is the slow defect of transmission speed, PCI is adopted to turn the expansion card scheme of USB2.0, each pci card expands 5 USB port, the program not only greatly improves law-enforcing recorder data efficient and uploads, and the transmission speed also having given full play to pci card is high, traffic large, the advantage of good stability.

For achieving the above object, the utility model adopts following technical scheme:

A kind of multichannel usb data high speed acquisition workstation, comprises main frame, industrial control mainboard, massive store unit, gathers frame, direct supply, display, it is characterized in that:

Insert 5 PCI in the pci expansion slot of industrial control mainboard and turn usb card, each PCI expands 5 USB interface, and such industrial control mainboard can access 25 law-enforcing recorders at most simultaneously;

Massive store unit is multiple jumbo hard disk compositions, and be linked in main frame, acquisition workstation is stored in local massive store unit from the data that law-enforcing recorder copies;

Gather the containing case having 24 freight spaces in frame, law-enforcing recorder puts into this freight space, and is connected to the main frame of acquisition workstation by USB interface;

Direct supply is external power supply, is to power to 5 PCI specially, makes up the deficiency that built-in power in main frame is powered;

Display is mainly used in showing the current connection status of law-enforcing recorder, uploading state, upload progress, and when the management enforces the law registering instrument, is convenient to man-machine interactive operation.

Multichannel usb data high speed acquisition workstation as above, is characterized in that, also comprise central server, and after acquisition workstation completes local storage, the information that law-enforcing recorder is relevant, remote transmission is on central server.

The utility model compared with prior art tool has the following advantages: this acquisition workstation turns usb expansion card by PCI, control 24 registering instruments and automatically upload electronic evidence to acquisition workstation, electronic evidence in the instrument of deletion record simultaneously, realize multichannel usb data high speed concurrent transmission, this brings great convenience not only to security personnel and law enforcement agency, also substantially increases their work efficiency.

Accompanying drawing explanation

Fig. 1 is acquisition workstation work structuring schematic diagram of the present utility model.

Fig. 2 is the connection layout that PCI turns usb expansion card and acquisition workstation mainboard.

Embodiment

In order to understand the utility model better, illustrate content of the present utility model further below in conjunction with embodiment, but content of the present utility model is not only confined to the following examples.Those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values are equally within claims limited range listed by the application.

As shown in Figure 1, the acquisition workstation of the utility model patent comprises:

Mainboard, adopts industrial control mainboard, mainboard has 5 PCI slots, is convenient to insert the expansion card that PCI turns USB, and on each pci card, expansion has 5 USB interface, and 5 pci cards can access 25 registering instruments simultaneously, and the freight space of acquisition workstation containing case put into by registering instrument.Consider that acquisition station containing case customized only has 24 freight spaces, therefore a reserved USB port is for subsequent use.

PCI turns usb expansion card.As the pci card be inserted on mainboard of Fig. 2, for self-control PCI turns usb expansion card, because expansion card is more, and recorder device is large driven current density equipment, only power by the built-in power in main frame, be not enough to activation record instrument normally work, therefore this pci card is that PCI turns usb expansion card and powers by external direct current power supply equipment, then realizes uploading electronic evidence by the USB activation record instrument on pci card.

Massive store unit.Massive store unit as shown in Figure 1, for multiple jumbo hard disk composition, be linked in main frame by magnetic (RAID) (disk array), after acquisition workstation copies electronic evidence to from registering instrument, be stored in this local massive store unit.

Central server.After acquisition workstation completes local storage, the information that registering instrument is relevant, as thumbnail, utilize Socket interface, by arranging the IP address of server, remote transmission, on central server, is convenient to managerial personnel and is consulted and file.

Display.Collecting work stands in and controls registering instrument when uploading electronic evidence, and display recorder current state, comprising: equipment serial number, connection status, upload the registering instrument information such as state, upload progress, excess time, priority setting, charged state.

The workflow of this acquisition workstation is: by law-enforcing recorder acquisition software, acquisition workstation passes through USB interface, control 24 registering instruments simultaneously and automatically upload electronic evidence, and these data storage uploaded in local massive store unit, delete the electronic evidence uploaded in each registering instrument simultaneously.In the process uploading these data, can charge to registering instrument, if be transmitted, then show the information be transmitted; The acquisition software of acquisition workstation, by Socket interface, carries out alternately, the thumbnail information uploading registering instrument being uploaded in the database of management platform, being convenient to managerial personnel and consulting with the massive video management platform software of central server, files and management.

This acquisition workstation adopts industrial control mainboard, independent research PCI turns USB2.0 high-speed collection card, expanded by high-speed bus bandwidth, USB2.0 transmission speed can be played most possibly, be automatically imported average velocity and can reach 30MB/s, guarantee 24 law-enforcing recorders, every platform 32GB capacity has been automatically imported in 12 hours, on uploading speed, lead over the employing usb2.0 hub scheme of current main-stream.

The content be not described in detail in this instructions belongs to the known prior art of professional and technical personnel in the field.
