YANG Xing-hong, HUANG Jiao, LU Xiao-chun, et al. Design of intelligent magnetostrictive liquid level gauge[J]. 2016, 35(3): 118-120+123. DOI: 10.13873/J.1000-9787(2016)03-0118-03.
Aiming at several problems in liquid level measuring and monitoring system
a high-precision intelligent magnetostrictive liquid level gauge is designed. The system uses ARM Cortex-M4 EK—TM4C1294NCPDTI chip as core control processor
includes of power supply module
clock module
excitation signal modules
signal detection module
ethernet interface module
fault alarm module
data storage module
etc. Realize intelligent liquid level gauge with networked communication function
which has high precision
good stability and friendly humancomputer interface( HCI).
