[0013] In order to have a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific implementation manners of the present utility model will now be described with reference to the accompanying drawings.

The method or device may also include other steps or elements.

[0016] Currently, some maintenance personnel use a handheld thermometer to measure the temperature of the platform board regularly, or place environmental monitoring equipment in the equipment room to only monitor the environmental temperature and humidity, without monitoring the equipment. These measurement methods are only carried out outside the platform and cannot penetrate into the platform interior, and cannot reflect the real operating environment of the platform board, especially for a platform that has been running for a long time. This platform adopts a "cabinet" design. The back of the platform motherboard is sealed, and the front interface uses a CPCI interface to install the board. If it is necessary to measure the voltages of each path of the motherboard, it is necessary to connect the test probe into the cabinet for measurement, which is difficult; and it is necessary to measure under the condition that the equipment is shut down, and the power supply state of the motherboard during the operation of the platform cannot be grasped.
