Automatic water measurement monitoring system for irrigated area water measurement channel

Abstract

The present invention discloses an automatic water measurement monitoring system for an irrigated area water measurement channel. The system comprises a pedestal and a standing pole, the standing poleis fixedly installed on the pedestal, the middle portion of the standing pole is provided with a groove, the groove is internally provided with an electronic automatic water measurement device; and two input static pressure liquid level transmitters are arranged at the lower portion of the standing pole. When the automatic water measurement monitoring system is used, the two input static pressureliquid level transmitters are respectively installed at the upstream and the downstream of a channel and are separated by a spring hole, and an operation module is arranged in the electronic automatic water measurement device to calculate the water level, the flow and the water quantity and display the water level, the flow and the water quantity in real time or remotely send the monitoring datato a monitoring center through a GPRS module. The automatic water measurement monitoring system is accurate and reliable in measurement and ultralong in working hours, can perform all-weather measurement and is convenient to install, can achieve real-time monitoring and record for the water level, the flow and the water quantity on site or in a remote mode, can achieve an irrigation canal 'water meter' function and can provide accurate and real-time data for the agricultural irrigation water and a caution action.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, and relates to an intelligent real-time monitoring device for water level, flow and water volume, in particular to an automatic water measurement monitoring system for water measurement canals in irrigation areas. Background technique [0002] The No. 1 Central Document issued in 2015 made reform arrangements for many fields of agriculture, and promoting comprehensive reform of agricultural water prices is one of them. The monitoring of water level, flow, and water volume information of farmland irrigation canals can not only enable the management department to understand the hydrological conditions of each section of the canal and make timely countermeasures, but also the water level, flow, and water volume information of irrigation canals itself is the basic data for calculating water consumption. Provide data support for water consumption pricing of irrigation canals. [0003] Exi...

Problems solved by technology

[0003] Existing measuring devices are mainly relatively sophisticated electronic measuring instruments for water level and water depth measurement of large rivers, large rivers, large lakes or important rivers; real-time remote monitoring of water levels for small rivers, shallow lakes, ponds and irrigation canals, etc. Especially when synchronous data monitoring is carried out for all research rivers, since the water level measurement of irrigation canals has the characteristics of many and scattered measurement points, a large number of measuring instruments are required for simultaneous measurement, and the use of sophisticated electronic measuring instruments is too expensive and impossible to achieve Real-time monitoring of flow and water volume; while the use of basic water gauges or measuring ropes can only obtain water level data, and manual calculation of the flow and water volume of the canal is required. The entire operation process is cumbersome, time-consuming, and laborious, and is easily affected by human factors. The error is large, and the measurement reading at night is inconvenient, resulting in a larger error
