Abstract
The utility model relates to an open channel flow automatic measuring device, particularly to an open channel flow real-time measuring device adopting a simple measuring weir as a water measuring terminal. The device is characterized by comprising a simple measuring weir, an ultrasonic flowmeter and a remote communication module, wherein the simple measuring weir is arranged on the open channel; the ultrasonic flowmeter obtains the water level data through automatically measuring the upstream water level of the simple measuring weir; and the remote communication module performs data exchange with the ultrasonic flowmeter as well as remote transmission for the measuring data to a remote central station. The device fully combines the characteristics of the traditional water measuring approaches (the simple measuring weir), such as strong suitability, high precision and low construction cost, as well as the advantages of the modern information technology such as quickness and convenience.
Description
Technical field
The utility model relates to a kind of open channel flow rate auto-measuring device, particularly a kind of open channel flow rate real-time measurement device that is the water gaging terminal with simple and easy water gaging sill.
Background technology
Agricultural water is the water rich and influential family of national economy.At present, 70% of national total water amount is an agricultural water, and the part water-deficient area reaches more than 80%.From our province water situation, the agricultural water amount accounted for total water amount 45%～50% in recent years, and the agricultural irrigation water conservancy only is 0.55 with coefficient, and to compare overall utilization ratio not high with the advanced area of water saving, and agricultural water conservation has a high potential.The irrigated area water gaging is basic a, guardian technique of agricultural water conservation.The irrigated area water gaging for strengthen the field irrigation water using planning, advance agriculture water pricing reform and water rate collect, realize water resource efficiently, sustainable use etc. is significant.
Water resource situation for the sternness of reply China, ensure the sustainable development of socio-economy, China will implement the strictest water resources management system, wherein the measure monitor to agricultural water proposes to explicitly call for, national big-and-middle-sized irrigated area intake water metering rate reached 80% in promptly 2015, and the above water metering rate of quarrel reaches 50%.Therefore, along with the enforcement of the strictest water resources management system, press for and promote a kind of simple and practical irrigated area canal system water gaging device.The water gaging device of promoting should satisfy the economic, practical requirement of water gaging, should show good operability again, the automaticity height, and have measurement accuracy preferably.
Simple and easy water gaging sill belong to a kind of of weir, as shown in Figure 1, are researched and proposed by Holland, the U.S. etc. the earliest.Relevant scientific research department of China Ministry of Water Resources has done certain improvement on the basis of introducing.Rig-site utilization by a plurality of irrigated areas shows, its measurement accuracy is higher, also have in addition: characteristics such as cheap, open-air adaptability is strong are the comparatively desirable measuring structures in irrigated area, recommended entering " irrigation canal system water gaging standard " (GB/T 21303-2007).
At present, simple and easy water gaging sill have been applied to the agricultural water metering of irrigated area open channel, the main method that adopts: build simple and easy water gaging sill by code requirement on the open channel of irrigated area, and in the sill upstream water gauge is set; During the irrigation, by the simple and easy water gaging sill of the on-the-spot copy reading of artificial timing upstream water gauge waterlevel data, formula rule of thumb again, information such as manual analytical calculation real-time traffic and accumulative total water consumption.The operation of need manually showing up of this mode can not realize operated from a distance, wastes time and energy.
Summary of the invention
The utility model is the water gaging primary instrument with simple and easy water gaging sill, in conjunction with modern information technologies, information such as the water level of the on-the-spot channel of collection irrigated area agricultural irrigation in real time, flow, water consumption, and, satisfy the requirement of modern irrigated area agricultural water management to water gaging with the infosystem (central station) of wireless mode teletransmission to administrative center.
Simple and easy water gaging sill formula open channel flow rate real-time measurement device, it is characterized in that described device comprises simple and easy water gaging sill, ultrasonic flow meter, remote communication module, simple and easy water gaging sill are arranged on the open channel, ultrasonic flow meter obtains waterlevel data by the simple and easy water gaging sill of auto-measuring upper pond level, remote communication module and ultrasonic flow meter carry out exchanges data, and with the real-time teletransmission of metric data to remote central station.
The simple and easy water gaging sill upper pond level data that ultrasonic flow meter records are carried out exchanges data with remote communication module after being calculated as metric data automatically by built-in firmware.
Described remote communication module is the GSM/GPRS module.
Simple and easy water gaging sill are with reference to code requirement, design in conjunction with the irrigated area channel condition, and as the primary instrument of this device;
Ultrasonic flow meter is according to the parameter instruction of central station Remote configuration, on request (as the sampling time) obtain simple and easy water gaging sill upstream real time water level data automatically;
After ultrasonic flow meter obtains waterlevel data, calculate data such as real-time traffic, accumulative total water consumption automatically by built-in firmware;
Ultrasonic flow meter and GSM/GPRS module are carried out exchanges data;
The GSM/GPRS module with the field measurement data with the infosystem (central station) of the real-time teletransmission of wireless mode to administrative center;
The data acquisition and the transmission of a new round are carried out in the instruction of the Remote configuration parameter of GSM/GPRS module real-time response central station.
This device fully combines conventional amounts sailor section (the simple and easy water gaging sill) characteristics that adaptability is strong, precision is high, cost is low, and the present information art fast, advantage easily.
