Water regimen monitoring platform and monitoring method

Abstract

The invention relates to the field of water regimen monitoring devices, in particular to a water regimen monitoring platform and a monitoring method. The system comprises a main server and at least one data collection group connected with the main server. The data collection group comprises an agricultural water quantity monitoring node and a wireless transmission module; the agricultural water volume monitoring node comprises a CPU module, a liquid crystal module and an AC detection module. The input end of the CPU module is in communication connection with the AC detection module, and the output end of the CPU module is connected with the liquid crystal module; the CPU module is in communication connection with the wireless transmission module through the communication module; based on the comprehensive utilization perspective of water regime data, a rural irrigation water volume monitoring and management system is formed from full-cycle management such as station flow calibration, water volume collection, transmission and analysis processing.

Description

Technical field [0001] The invention relates to the field of water regime monitoring devices, in particular to a water regime monitoring platform and a monitoring method. Background technique [0002] There are more than 100 types of water regime monitoring equipment currently in use. It can be roughly summarized into the following categories. Use hydraulic structures to measure water, use water gauges to measure water, special water measuring equipment to measure flow, use meter-type flow meters to measure water, automatic water measurement, and other estimation methods. [0003] Water measurement methods have their own advantages and disadvantages. The use of hydraulic structures to measure water is more economical and simple. If possible, priority should be given to utilization. The disadvantage is that different types of hydraulic structures need to be calibrated one by one, which requires a lot of work. The water gauge is intuitive and simple to measure water, but it is easi...

AI Technical Summary

Problems solved by technology

[0003] Water measurement methods have their own advantages and disadvantages. It is more economical and convenient to use hydraulic structures to measure water. If possible, it should be used first. The disadvantage is that different types of hydraulic structures need to be calibrated one by one, and the workload is heavy.

The water gauge is intuitive and simple to measure water, but it is easily affected by the backwater of downstream control gates or backwater buildings

Using special water measuring facilities such as weirs and flumes to measure water, the relationship between water level and flow is relatively stable, but it is necessary to select and build new water measuring facilities according to different conditions

It is not suitable to use water meters to measure water because of unstable irrigation water quality. Electromagnetic flowmeters and ultrasonic flowmeters have the disadvantage of high equipment costs. Velocity meters can accurately measure instantaneous point flow, but the flow measurement operation is cumbersome and is not suitable for measuring water level and flow. channel over water

Indirect estimation of electricity and fuel consumption is relatively simple, but the relationship between indirect indicators and flow will change with external conditions, which may easily cause errors

[0004] There are many studies on water regime measurement, mainly focusing on single-site water monitoring, insufficient utilization and sharing of water regime monitoring data, and few large-scale applications of multi-site water regime monitoring in the entire irrigation area
