Description

A kind of novel radio temperature data registering instrument

technical field:

The utility model belongs to wireless environment monitoring technique field, is specifically related to a kind of novel radio temperature data registering instrument.

background technology:

Temperature is as an important physical quantity, is one of the most general in industrial processes, most important technological parameter.

The working method of traditional humiture registering instrument is comparatively loaded down with trivial details, be placed in traditional humiture registering instrument of the environment point of required test, record after the detection data of a period of time, registering instrument need to be taken off, by data line by the detection data transmission in registering instrument to computer.Owing to not being real-time measurement, traditional humiture registering instrument is difficult to see instant data; If want to see instant data, the environment point that need to send special personnel to test in the past, checks the data that show on registering instrument, and this can impact detecting the accuracy of data.

In many industrial applications, especially for scene some dispersions, unattended, need to carry out collection and monitor to temperature data.In monitor procedure, more and more higher to the requirement of temperature measurement range and automaticity, therefore improve temperature detection technology and have important practical significance.

Along with the digitizing of instrument and meter and the development of wireless communication technology, utilize wireless communication technology can realize easily closely and remote temperature acquisition and status monitoring, reduce to a great extent user's maintenance cost, be more conducive to administering and maintaining of temperature data.
