Description

Technical Field

[0001] The present application relates to the technical field of temperature collection, and in particular to a wireless temperature collection device. Background Art

[0002] Before a new vehicle is officially put into use, many temperature-related tests must be conducted. Some special-purpose engineering vehicles need to be tested in high-temperature and high-cold environments. Since some temperature collection points cannot be equipped with data transmission lines, wireless temperature sensor nodes are required for signal collection. The existing wireless temperature collection device has a small temperature collection range and is not suitable for signal collection in harsh environments of high temperature and high cold.

[0003] In addition, during the test, engineering equipment often produces strong vibrations, and the wireless temperature sensor nodes need to be specially fixed. There are no special mounting holes or other positioning mechanisms near the test points. Therefore, it is necessary to use magnets with strong magnetic attraction to position the sensor nodes. If permanent magnets are used for positioning, excessive magnetic force will make disassembly difficult. Existing wireless temperature acquisition devices do not have a good installation and positioning method.
