Description

Technical Field

[0001] This invention relates to the field of thermal imagers, and in particular to a portable universal thermal imager display and control system. Background Technology

[0002] As the functions and technologies of thermal imagers continue to evolve, the differences between them are becoming increasingly significant. Video output formats, power supply voltages, and communication protocols all vary. Currently, the common display and control methods involve equipping each thermal imager model with a single corresponding acquisition card, image display computer, and control device, or integrating the monitor and control panel into a single display and controller. When different models of thermal imagers need to be displayed and controlled, different display and controller devices or different monitors and control devices are required. Operating multiple models of thermal imagers simultaneously requires multiple video monitors and control devices, resulting in complex workbench setups, inconvenient operation, limited mobility, and significant difficulties in field operations.
