Title The circuit design of high-precision three-dimensional magnetic field measurement
Abstract
The accurate measurement of the magnetic field in the modern life is an
important issue. This issue meets the requirements of accurate measurement
of the magnetic field, through the circuit design of a high-precision
three-dimensional magnetic field measurement and simulation.
This paper detailed describes circuit design process of the magnetic,
including hardware design process, such as the choice of the magnetic
detection sensor, the A / D components and CPU models, schematic and PCB
design. It also includes the design process of the program. this project
makes full use of the KEIL μVISION to simulate the measurement circuit
of magnetic field. During the simulation, two serial ports of the same
computer connect together through the RS-485 to achieve communication
between single machine. μVISION takes the part as the next crew, inputs
the analog data, collects data and transmits, while the host computer sends
commands and receives data.
