Multi-path USB data high-speed collection workstation

Abstract

The invention provides a multi-path USB data high-speed collection workstation which comprises a host, an industrial control mainboard, a large-capacity storage unit, a collection frame, a direct current power source and a displayer. The multi-path USB data high-speed collection workstation is characterized in that the collection workstation can be connected with 24 site enforcement recorders at the same time through 5 PCI-to-USB expansion cards and USB ports; collection software of the collection workbench controls the recorders to automatically upload and store electronic evidence to a local storage unit of the collection workstation and then upload thumbnails of the recorders to a center server. According to the scheme, the efficient data uploading efficiency of the site enforcement recorders is greatly improved, and the advantages of the PCI card that the transmission speed is high, the communication capacity is large and the stability is good are brought into full play.

Description

technical field [0001] The invention relates to a collection workstation, in particular to a multi-channel USB data high-speed concurrent collection workstation. Background technique [0002] The collection workstation of a police station needs to process multiple body-worn recorders for data upload. If the recorders are uploaded one by one, the upload efficiency is obviously too low. Once the electronic evidence in the law-enforcement recorder cannot be uploaded in time, law enforcement officers can quickly carry out their duties The task will be blocked; if multiple recorders are allowed to upload electronic evidence at the same time, especially when uploading recorders with more than 16 USB ports, the maximum drive current carried by the main board is limited, and the main board cannot drive the recorder to work normally, or The upload speed is too low, or the software cannot run normally; if it is serious, it will cause a crash, blue screen crash of the system, etc. [...

[0002] The collection workstation of a police station needs to process multiple body-worn recorders for data upload. If the recorders are uploaded one by one, the upload efficiency is obviously too low. Once the electronic evidence in the law-enforcement recorder cannot be uploaded in time, law enforcement officers can quickly carry out their duties The task will be blocked; if multiple recorders are allowed to upload electronic evidence at the same time, especially when uploading recorders with more than 16 USB ports, the maximum drive current carried by the main board is limited, and the main board cannot drive the recorder to work normally, or The upload speed is too low, or the software cannot run normally; if it is serious, it will cause a crash, blue screen crash of the system, etc.

[0003] The current mainstream technology to solve this problem is to use the usb2.0 hub solution, that is, to expand multiple USB outputs through a USB input interface on the motherboard, and the recorder is connected to the host through multiple USBs. The USB2.0 transmission speed is theoretically 60MB / s, if you expand 5 USB ports, the average upload limit speed of each recorder is 12MB / s, the actual upload speed will be limited by the disk I / O read and write speed, the actual upload speed is difficult to meet the current workstation The need to efficiently import large volumes of data
