Intelligent water level monitor based on data fusion technology

Abstract

The invention discloses an intelligent water level monitor based on a data fusion technology. The monitor comprises a touchscreen unit for manually correcting and setting the altitude, upper and lowerlimits of water level, proportion and correcting parameters of an input and output unit and performing warning prompts, a programmable controller unit used for conducting comparison and analysis on the water level monitoring data transmitted by the input and output unit, and the input and output unit used for monitoring water level data. According to the monitor, measurement is sensed simultaneously by using multiple sensor units, the output of the monitor is the calculation value obtained through a data fusion algorithm, and according to an error theory, the measuring accuracy of the water level is significantly improved; a temperature compensation mechanism is introduced, which can reduce measuring errors brought by temperature variations; by means of the monitor, a malfunctioned waterlevel sensor can be intelligently recognized, and automatic calibration and correction can be conducted on the water level sensor, so that mean time between failures of water level monitoring equipment is increased and operation and maintenance workloads are reduced.

Description

technical field [0001] The invention belongs to the technical field of water level monitoring, in particular to an intelligent water level monitor based on data fusion technology. Background technique [0002] Current water level measuring instruments mainly include float water level gauges, piezoresistive water level gauges, radar water level gauges, ultrasonic water level gauges, electronic water gauges, etc. Due to the harsh on-site working environment of water level measuring instruments, the failure rate of optoelectronic devices in these instruments is very high. The high temperature makes the entire water level measuring instrument unable to work, leading to the failure of the entire automatic control system, and even causing disasters. [0003] Current water level sensors generally have a series of problems such as time drift, temperature drift, accuracy, anti-interference ability, and stability. The water level measuring instrument was unable to work, resulting in ...
