USB3.0 high-speed high-definition industrial camera

Abstract

The invention belongs to the technical field of electronic communication and discloses a USB3.0 high-speed high-definition industrial camera. The camera comprises an optical lens, an industrial CCD (Charge Coupled Device), a high-precision CCD front end and a USB3.0 master control module, wherein the USB3.0 master control module comprises a USB3.0 microkernel processor, a camera controller and a real-time data storage area; the USB3.0 microkernel processor is an operation processing unit of the USB3.0 master control module and is connected with a host machine controller of a master control computer through an end point 0; the data input interface of the real-time data storage area is connected with the digital image signal output interface of a high-precision ADC (Analog to Digital Converter) of the CCD front end through a data bus; the data output interface of the real-time data storage area is connected with a USB3.0 real-time end point; and the output interface of the camera controller is used for outputting a camera control signal to a CCD front end controller through a camera control bus. The USB3.0 master control module is used for replacing signal transmitting devices, such as a DSP (Digital Signal Processor), an ARM (Advanced RISC Machine) and an FPGA (Field Programmable Gate Array), in the prior art, so that the USB3.0 high-speed high-definition industrial camera has the advantages of low transmission speed, low cost, simple circuit, stable and reliable system, simple interface and convenience in connection.

Description

technical field [0001] The invention relates to the field of cameras, in particular to the field of high-speed high-definition optical detection and image transmission for industrial detection and monitoring, and specifically refers to a USB3.0 high-speed high-definition industrial camera and a USB3.0 video collection and transmission method thereof. Background technique [0002] Industrial cameras are widely used and can be used for dimension measurement, paper defect detection, light environment monitoring, quantity statistics, waste sorting, etc. At present, the data collection and transmission methods of industrial cameras are mainly through storage, processing, compression and uploading to the computer through the network cable. However, data compression will destroy the original sampling data, and it is difficult to find a convenient interface to achieve high-speed transmission without compression. For example, the network cable interface on an ordinary computer has a...

Problems solved by technology

However, ordinary computers with high data transmission speeds such as 1394 interfaces and camalink interfaces do not have them at all.

And if you want to use the interface on the ordinary computer, you have to add a data processor and a memory, resulting in an increase in cost.
