An Intelligent Water Level Monitor Based on Data Fusion Technology

Abstract

The invention discloses an intelligent water level monitor based on data fusion technology. The monitor comprises: a touch screen unit for manually calibrating and setting the elevation, upper and lower limits of the water level, scale and calibration parameters of an input and output unit, and alarming and prompting ; The programmable controller unit is used to compare and analyze the water level monitoring data transmitted by the input and output units; the input and output units are used to monitor the water level data. The invention utilizes multiple sensing units to sense the measured value at the same time, and its output is the calculated value obtained through the data fusion algorithm. According to the error theory, the measurement accuracy of the water level will be significantly improved; the temperature compensation mechanism is introduced into the device, which can reduce the temperature change zone. The device can intelligently identify the faulty water level sensor, and can automatically calibrate and calibrate the water level sensor, thereby improving the mean time between failures of the water level monitoring equipment and reducing the workload of operation and maintenance.

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 ...

Problems solved by technology

[0006] The purpose of the present invention is to provide an intelligent water level monitor based on data fusion technology, aiming to solve the problem that the photoelectric devices in the current water level measuring instrument have a high failure rate and thus make the entire water level measuring instrument unable to work, resulting in the failure of the entire automatic control system; The lightning and lightning strikes of the water level sensor in the water level measuring instrument under harsh weather conditions can easily cause frequent failures of the water level sensor, which in turn makes the entire water level measuring instrument unable to work, leading to the failure of the entire water delivery dispatching automation control system, and even causing major safety hazards. Accidents; the measurement error of the water level sensor is large and the equipment needs to be calibrated and corrected frequently, which increases the workload of maintenance personnel and equipment maintenance costs; the data measured by each sensor are independent of each other, cannot support and correlate with each other, and cannot improve water level monitoring.
