Description

Crawler

Technical field

The present invention relates to it is a kind of can be special to the device that is downloaded comprising the data including video, voice and character pattern Be not related to it is a kind of portable and can field data is quick-downloading, storage, processing and forwarding crawler.

Background technology

In the prior art, the instrument that can be downloaded to data information mainly has following three kinds：

1st, USB flash disk or mobile hard disk

Data information can be downloaded, stored and unloading.

It has the drawback that：

1) memory capacity is small：USB flash disk memory space on the market is generally 16GB, 32GB, 64GB etc., far can not meet big The requirement of capacity data storage.

2) security coefficient is low：

Although a. function of some USB flash disks with data encryption, without unified standard, therefore, the USB flash disk can only limit Used on the computer of compatible encryption software is installed；

B. when the data volume being downloaded is larger, a USB flash disk can not be completed, can only be by data sharing in multiple USB flash disks, so Easily cause data management confusion and shortage of data.

3) security is poor：USB flash disk small volume, it is easy to lose or stolen.

4) function is single：USB flash disk can only store and unloading, it is impossible to carries out Real-time Feedback and real-time Transmission to data.

2nd, business notebook computer/business flat board

It can be downloaded to data information, store and unloading.

It has the drawback that：

1) security is poor：The unshielded structure on shell, i.e., in use, fall or and miscellaneous part accidentally if having Collision, easily causes its damage.

2) data acquisition interface is single：Without the data acquisition interface needed for other special industries, moreover, downloading data Speed is slow, is unfavorable for carrying out big data download.

3) it is inconvenient to carry：External accessory and wire rod are more, loaded down with trivial details using operating, meanwhile, accessory line is more, easily forgets Carry or lose.

3rd, other combination devices

Such as the crawler (as video display show business configures) of specialty, data can be downloaded, stored and unloading.

It has the drawback that：

1) volume is necessarily large and bulky：This kind of customized type equipment is led to because volume is big, heavy is unfavorable for user of service and carried Often, in use, needing more people to move.

2) poor compatibility：This kind of customized type equipment only possesses partial data download interface, can only adapt to partial data download Application scenario.The data of collection in worksite can not be carried out with processing and preview in real time, the processing in real time and preview are included in following Hold：At the scene that data are downloaded, the data of download are entered with row format conversion, data screening, critical data using crawler The data of download are carried out refinement analysis in the very first time, fast and effectively section are provided for follow-up judgement by analysis and crawl etc. Learn foundation.

Maintain social stability, prevent that investigation is likely to cause harm to the country and people probably attack hidden danger event and pernicious During the criminal investigation of case, Guoan or criminal detective need to transfer and download to be regarded by what related safety monitoring equipment was recorded Frequently, the data message such as voice or character pattern, but above-mentioned several mobile hard disks or crawler can not meet such event The data of middle vast capacity are downloaded, forward and analyzed.

The content of the invention
