The data acquisition station adopts integrated design technology to integrate the charging service, data upload service, space management service and time synchronization service of the law enforcement instrument into the acquisition station. Whenever the police insert the law enforcement instrument into the USB port of the acquisition station, the system can automatically detect the law enforcement instrument and check the data files in the law enforcement instrument, If new files are found, these new files will be uploaded automatically. After uploading, empty the uploaded files and make space available for next use. While uploading files, the collection station realizes charging and time synchronization services for law enforcement instrument through USB.

Background management system

The management platform adopts flexible and intelligent storage and communication technology, which can support the storage of multiple data structures and adapt to various networks and storage structures:

Architecture 1: the storage architecture is the most basic storage network architecture. Only one data acquisition station can complete the charging, data acquisition, data storage, emptying, automatic timing, etc. of multiple law enforcement recorders. The video playback and management can be completed on the acquisition station, or the video can be played on other computers through the LAN.

Architecture 2: this architecture is characterized by centralized storage of video and image data of all units. In design, it needs to be equipped with a special server to store file index information and run the application service intermediate program on the server. In addition, it needs to use a server or disk array with large hard disk space in the data center to store video, image, audio and other files, The collection stations and servers of all units are networked. The collected law enforcement recorder data are centrally stored in the disk array of the data center. Users can access the application server through the client program to play video, image, audio, file management and other operations.

Architecture 3: this method is suitable for multiple collection stations. It needs to be equipped with a special server, use the storage space of the collection station to store data, automatically store index information on the server designated by the data center, and access the server through the client to view and manage files.
