Temperature is a common physical quantity in life. It is related to our real-time life. Human research on temperature has been continuing. After many years of development, many mature temperature sensors have been well applied in various fields. The following introduces the classification of temperature sensors and the method of selecting temperature sensors in design.

In the analysis of call failure events, it is found that many call failure reasons are due to the failure of the caller or the called user’s Rab assignment. This phenomenon has no regularity, resulting in low CS connection rate. Through the analysis and positioning of this problem, this paper summarizes the 1 bit rewrite

Aiming at the problem that the internal working mechanism of the fuzzy controller is unknown, an interval type 2 (IT2) fuzzy PI/PD controller is proposed, and the analytic structure of the IT2 fuzzy controller is deduced. The Fuzzy Controller adopts Mamdani rule form and assigns only two IT2 fuzzy sets to each input variable. It
