A System of Infrared Temperature Measurement
Based on Single-chip Microcontroller
Abstract
Infrared temperature-measuring in the process of product quality control and
monitoring, equipment, equipment on-line fault diagnosis safety protection and energy
saving etc plays a very important role. Temperature of objects above absolute zero, the
molecules are due to their own movement, the infra-red radiation. Through the
infrared detector we can change the power signals which objects radiate into electrical
signals. Infrared detector will absorb the radiation into heat, thereby increasing the
temperature detector, and temperature data into electronic signals, amplified
displayed. Infrared temperature-measuring broke traditional temperature measurement
model, and long-distance non-contact measurement, the response speed and high
precision measurement, the measurement range and simultaneous measurement of
environmental temperature and temperature characteristic, measurement target
distance can reach 30 meters.
SCM has small, strong function, low cost, application, advantages and intelligent
control and automatic control of single-chip microcomputer in the core is, inspection
and control system has been widely used in the system, the temperature is often need
to measure and control and maintain a quantity.
This paper introduced the use of single chip microcomputer temperature control
system design process, and based on single-chip microcomputer control technology,
the infrared temperature measurement system using a serial interface (SPI) interface
of periphery of infrared temperature sensor TN series, signal measuring temperature
measuring temperature and environmental temperature, the goal and the measurement
data to SPCE061A processing, after that, at the same time sent by using the function
of speech broadcast SPCE061A temperature. The thermometer to its accurate
measurement of quick, transparent function of digital display convenient People's
Daily life, speech function makes it more intelligent and user-friendly.
