Use: irrigation canals, irrigation, drainage, etc.

System Introduction

At present irrigation water measurement tasks are heavier, the last manual measurement and scheduling methods have been difficult to meet the modernization of irrigation management, the automation of measurement and irrigation scheduling will become the mainstream of water management and decision-making trends.

For the field of water to the scene to direct reading instrument is the amount of water in the direction of development, but for more decentralized control devices is not easy to show the shortcomings of centralized control, the amount of water is not conducive to automated, centralized management of optimizing the efficiency of automation. Orchid Island, Tiancheng Technology Co., Ltd. for the development of irrigation problems SCADA Irrigation District water control system that uses superior performance sensors, processing systems, the formation of technologically advanced automatic water measurement system, through the GPRS wireless technology to the front to the scheduling of data transmitting Centre. Its automated real-time measurement of water saving reform and real-time flow measurement monitoring, will bring good returns to the irrigation area, irrigation not only reduce the workload of the masses, but also for irrigation brought to significantly increase agricultural productivity, but also improve the efficiency of agricultural irrigation water. 

Design Principles

1) Applicability: As the site requires special, try to select a mature technology, high reliability of the transmission program, but points to pursue advanced technology to achieve the monitoring and control system reliability.

2) The practical: a powerful, user friendly interface and complete reporting capabilities, traffic trends, routine maintenance simple and convenient. While guaranteeing to meet the application, but also reflect the advanced nature of GPRS network systems, network applications take full account of the status and future trends.

3) flexibility and scalability: In accordance with the needs and changes in future applications, should have full access capability and scalability, we use a standardized interface, such as the future system for Increasing I / O interfaces to facilitate easy configuration, set point of low cost, including the future expansion of bandwidth (3G accession), and control point shift scalability to maximize the reduction of network architecture and the adjustment of existing equipment.

4) compatibility and economy: the equipment ready, the reform must consider the cost and to maximize the network to ensure the future transformation of the existing types of computer hardware and software resources, availability and continuity, minimize network system's overall investment. 

System components

Irrigation remote measurement system, including: measuring point sensing devices, remote GPRS wireless data transmission terminal, power supply system, GPRS communication platform, control centers (Information Centre).

Monitoring point for measuring the current flow when the actual measurement data such as its data through the communication platform to present data to the monitoring center, monitoring center through the data analysis of survival data to the database and display the current status of data and check the history.

Measuring flow measurement in irrigation systems, water level measurement and flow measurement are the two basic elements.

Water level measurement is mainly achieved through the liquid level sensor. There are now more commonly used float level gauge, pressure sensors and ultrasonic level gauge water level.

Flow measurement in the measuring process, the size of the problem encountered channel flow, is generally based on branch canal lateral canal traffic flow, water flow relations are stable, usually recorded in the canal water level to calculate the dynamic changes of water, a very small range of fluctuation. The flow of agricultural drainage is small, unstable relations between water level and discharge, in this case required additional Barthel slot, by recording the dynamic changes in water level to calculate the water to pass. Agricultural drainage at the same time normally only one user of water, household water use by recording a start and end time, can measure the home. 

  System function

1, remote dynamic monitoring. Information Center remote call at any time by software testing irrigation level and flow data and historical records. Parameters can detect and report the corresponding screen is displayed, and the liquid level and flow according to the need for automatic generation of charts and reports, and classified for storage, receiving various forms of inquiry.

2, remote control functions. In the data center software remote control the level of the value of the warning water level.

3, large database features. All data are automatically stored in a central server of a large database, to facilitate historical data retrieval and data analysis.

4, analysis curve. Real-time curve drawn according to the database and the historical trend graph, you simply enter the name and select the appropriate parameters.

5, historical reports. According to the time period required by the different as day, week, year, month, etc. automatically generate various reports. The scope of the data storage interval of time can be arbitrarily designated start time can also be time to check. List of analysis to the data presented in tabular form, graphical form through the curve, column and pie and other graphic visual display.

6, extension. Change monitoring easy, set aside more than 40% expansion. 

Monitoring center

Adopt the standard framework for the construction of CS or BS standards issued by the external network. Orchid-day Robinson's current measurement center SCADA software can receive from each branch canal, lateral canal, agricultural drainage and agricultural drainage DTU under the control terminal of each data transmission up and processed. The software has data reception, data display, data storage, data query, reporting and many other features generated curve, and according to user requests access to the external interface.

Monitoring center receiving data from the server through IP address access to Internet network, using multipoint methods to construct a number of monitoring stations to receive the data sent

Simulated irrigation monitoring site configuration screen, dynamically display changes in front-end data, the user can self-monitoring center to set branch canal, lateral canal, agriculture channel names and data, as well as farmers under the agricultural drainage information, users can use their own meter adjust the farmers, control centers can be implemented for viewing, query and control the branch canal, lateral canal, drainage and agricultural use of water by farmers at different times, easy to understand the overall progress and without water irrigation timing of notice and decision-making.
