Description

Technical Field

[0001] This application relates to the technical field of industrial cameras, and more particularly to an industrial camera connection circuit with a PC terminal. Background Technology

[0002] In the field of industrial automation, industrial cameras, as core equipment for visual inspection and image acquisition, directly determine the real-time performance and stability of image data transmission through their efficient connection with PC terminals. Traditional industrial camera-PC terminal connection circuits often use a single interface for data transmission and power supply, a method with numerous drawbacks. Firstly, power fluctuations can easily interfere with data signals, leading to frame drops and distortion in image data, severely impacting industrial inspection accuracy. Secondly, a failure of a single interface can paralyze the entire system, making it difficult to meet the continuous production requirements of industrial operations.

[0003] While some existing connection circuits utilize USB 3.0 interfaces to improve data transfer rates, the lack of physical isolation between power and data channels fails to fundamentally resolve signal interference issues. Furthermore, in terms of power protection, most connection circuits only employ simple fuses and other protective devices. In the event of overcurrent, short circuits, or other abnormalities, manual fuse replacement is required to restore power, leading to prolonged system downtime and reduced industrial production efficiency. Moreover, traditional connection circuits lack versatility and expandability in their interface design, making them difficult to adapt to different models of industrial cameras and PCs, increasing equipment integration and maintenance costs. Therefore, there is an urgent need for an industrial camera and PC terminal connection circuit that offers efficient data transfer, reliable power protection, and good compatibility.
