Description

Technical Field

[0001] The present invention relates to the technical field of infrared equipment installation, and in particular to an infrared card machine used in a small enclosed space and an installation method thereof. Background Art

[0002] Infrared card cameras have natural advantages in monitoring small confined spaces due to their small size and ability to monitor external temperature in real time. As an advanced temperature monitoring technology, infrared thermal imaging technology is based on the principle of thermal radiation of objects. It captures and measures infrared radiation and converts these radiation signals into electrical signals to obtain the spatial distribution of the surface temperature of objects. In the field of power station temperature monitoring, infrared thermal imaging technology can greatly avoid electric shocks to workers through non-contact temperature measurement, and is relatively safe.

[0003] However, in the process of installing infrared card cameras, there are usually two installation methods: one is ceiling installation, that is, installing the fixed base plate of the camera on the ceiling, usually in the horizontal direction; the other is wall installation, that is, installing the fixed base plate of the camera on the wall, usually in the vertical direction. Although these two installation methods can meet basic installation requirements, they have some obvious shortcomings: 1. Whether it is suspended or wall mounted, infrared card cameras are usually fixed by bolts, adhesives, welding, etc. Once the monitoring position and angle of the infrared card camera are determined, it is difficult to adjust it later, which limits its use. This fixing method is particularly inconvenient when the monitoring angle or position needs to be adjusted frequently. 2. The environment of a small confined space is complex and changeable. Different equipment and structures may require different installation positions and angles. The existing installation method is difficult to quickly adapt to these changes, affecting the monitoring effect and system reliability; 3. Once the infrared card machine is installed, if maintenance or replacement is required, the original fixture must be removed first, which not only increases the workload but may also cause equipment damage.
