Conductive electronic water gauge and remote monitoring system thereof

Abstract

The invention provides a conductive electronic water gauge and a monitoring system thereof. The water gauge comprises a sealed cuboid stainless steel metal shell, a water level detection module arranged on the electronic water gauge and under the water level, and an information processing module for processing a detection signal of the water level detection module. An opening in the upper end of the electronic water gauge is connected with a monitoring module; the monitoring module comprises a timing unit used for monitoring and setting the time, a positioning unit used for monitoring and recording a detection position, a display unit used for displaying information collected by the electronic water gauge, a communication unit, a MYSQL database and a central processing unit; and the monitoring module is used for realizing communication between an upper computer and a lower computer through RS485. A single-row contact detection signal circuit using the conductive electronic water gaugeis simple in design and simple in process. For different measurement ranges, the measurement resolution is kept unchanged, and only the distance between contacts is relied on. Therefore, the conductive electronic water gauge has the characteristic that the sampling resolution is irrelevant to the length of a measuring body of a sensor.

technical field [0001] The invention relates to the technical field of electronic measuring water gauge and its monitoring, in particular to a conductive electronic water gauge for immersion water level measurement and a remote monitoring system thereof. Background technique [0002] Currently commonly used water level sensors mainly include mechanical, float, ultrasonic, pressure, bubble and other forms. The mechanical structure of these sensors is complex, the cost is high, and the measurement accuracy is greatly affected by the external environment. [0003] With the development of electronic technology, the contact type electronic water gauge has been widely used. However, the existing electronic water gauge structure is cumbersome, and the signal generation circuit and processing circuit include a bridge circuit, a sine wave generator, an analog multiplier and a filter. The circuit is complicated and the reliability is poor, and the anti-interference of the water gaug...
