Design of pressure detecting system based on single-chip
Abstract
Pressure is one of the important parameters in the process of industrial
production. Pressure detection or control is an essential condition to ensure
production and the equipment to safely operating, which is of great significance.
The single—chip is infiltrating into all fields of our lives, so it is very
difficult to find the area in which there is no traces of single-chip
microcomputer. In this graduation design， primarily through by using single-chip and
dedicated chip, handling of analog signal measured by the sensor to complete
intelligent function。 This design illustrates external hardware circuit design of
intelligent pressure sensor， and conduct software development to the hardware。
The design is based on measurement and display of AT89C51 single—chip。 This
is the pressure sensors will convert the pressure into electrical signals. After
using operational amplifier, the signal is amplified， and transferred to the 8-bit
A/D converter。 Then the analog signal is converted into digital signals which can be
identified by single-chip and then converted by single—chip into the information
which can be displayed on LED monitor， and finally display output. In the course of
show ， through the keyboard to input all kinds of data and commands into the
computer， the single-chip will locate in a predetermined function step to display
required values。
The end result of this design is that by downloading software to the hardware,
it will get the data which is required to display by debugging。 When the input analog
signals change ， the LED monitor will display different values through the A/D
