Overview of Integrated Intelligent Pumping Station for Farmland Irrigation

As an important part of farmland water conservancy construction, rural small-scale irrigation and drainage pumping station has the characteristics of large volume and wide area, and its design and construction quality directly affect the use effect of farmland water conservancy project construction. At present, China's farmland irrigation pumping station still adopts the traditional construction mode. The pumping room is generally brick-concrete structure, with large floor space, long construction time and diverse structure. The control mode of the pumping station is relatively simple, the degree of automation is low, and the management and maintenance are complicated. It is difficult to adapt to the development needs of agricultural modernization and informationization.

As a company affiliated to the irrigation and drainage center of the Ministry of Water Resources, after extensive on-site research and market analysis, and over a year of research and development, a new form of pumping station--MPPS integrated intelligent pumping station was launched. MPIS integrated intelligent pumping station is an intelligent integrated irrigation and drainage equipment based on IoT technology. It changes the concept of irrigation and drainage pump station in the traditional sense, and modern electrical control, process automation measurement and control, ultrasonic measurement, intelligent electrical protection. Infrared security monitoring, video process monitoring, water and property Internet technology and other integrated system integration with the pump unit, making it a mobile, combinable all-intelligent irrigation and drainage equipment.

The integrated intelligent pumping station adopts an integrated structure, which is compact and small in size. The exterior design is pavilion structure, the pump room adopts new environmental protection materials, and the floor space is generally no more than 6m2.

All components of the integrated intelligent pumping station are designed as standard parts, which are processed by the factory and transported to the site for most of the assembly. The construction of the pumping station is no longer a complicated civil engineering and equipment installation project, but a process of assembling and assembling a set of equipment on site. The project area has been greatly reduced, which has reduced the construction cost and construction difficulty of the pumping station and significantly shortened the construction period.

Structural principle

The integrated intelligent pumping station mainly integrates the following functional modules: new environmentally friendly material pump room, pump unit, vacuum pumping and water injection system, piping system, metering system, intelligent electrical system (including frequency conversion or soft start equipment), automatic control system (including All detection sensors), infrared security systems, video surveillance systems, emergency power systems, Internet of Things and water conservancy platform systems.

The main function

Local card swipe start and stop control

The integrated intelligent pumping station integrates intelligent devices such as energy meter, flow meter and IC card consumption system. Users can start and stop the pump station directly by brushing the IC card, and deduct the fee according to the local water resource tariff and electricity tariff. IC card The bottom line alarm of the balance and the automatic shutdown of the IC card amount after the use of the amount.

Remote terminal APP start and stop control

The integrated intelligent pumping station provides remote control function. The remote mobile terminal (mobile phone) APP starts and stops the pumping station. The operator can remotely monitor the pumping station without going to the site. At the same time, the auxiliary remote video can directly observe the operation of the site. The pump station is started and stopped remotely through the mobile terminal APP, and only the pump station administrator has control authority.

Equipment self-test and remote fault diagnosis

The integrated intelligent pump station is equipped with online monitoring and detecting components at each link to ensure that the pump station runs online transparently. Any abnormal information of any component can be timely fed back to the central controller and sent to the MPIS online service platform through the network. .

The integrated intelligent pumping station online service platform can start the fault diagnosis program to find the cause and repair online. It can also remotely and onlinely maintain each MPIS integrated intelligent pumping station online.

Infrared security

Infrared security system is an indispensable important equipment to solve the safety precautions of small-scale irrigation and drainage pumping stations in rural areas when they are not in operation.

The integrated intelligent pumping station is designed with an infrared security detection and alarm system. An infrared probe is arranged around the pumping station to ensure that all targets are detected in all directions. The infrared security system is linked to the video system to make the security protection visible, to play back and capture all moving objects that enter the perimeter of the pump station, accompanied by live voice warnings and prompts. If the entrant's legal identity cannot be confirmed within a certain period of time, and the entrant does not leave in time, the MPIS system will make an audible and visual alarm, and send the incoming information and the on-site snapshot picture to the user's mobile device (mobile phone) or 110 alarm center.

Control and information measurement

The integrated intelligent pumping station has a variety of optional starting modes: direct start control mode, soft start control mode and frequency conversion control mode. Direct start is generally applicable to pump stations with pump power less than 11KW. Pump units larger than 11KW generally use soft start control. The frequency conversion control method is generally applicable to pipeline constant pressure water supply irrigation.

Main motor protection functions: quick-break protection, overload protection, blockage protection, current loss protection, motor overheat protection, etc. The pump station integrates various types of sensors required for automation and informationization, and can measure the whole process parameters, including water consumption, power, river water level, pipeline pressure, host current, voltage, power factor, temperature and humidity in the pump station. The pump station realizes "one-button start", vacuuming, opening and closing the valve, judging whether the pipeline is full of water, etc. is automatically completed by the system without manual intervention.

Depending on the user's application requirements, constant pressure or constant current water supply can be operated. According to the choice of pump type (mixed flow pump, centrifugal pump, axial flow pump, submersible pump, etc.) to achieve various ways of control and operation.

Remote video surveillance

The integrated intelligent pumping station remote video monitoring system can provide 3-4 network video dome camera probes, real-time monitoring of the operation of the equipment in the pumping station and the real-time conditions of the pumping station outside the inlet pool, the outlet pool and the pumping station. The rotating dome camera can be adjusted as needed, and the dome camera can be remotely controlled by the mobile device (mobile phone) to obtain more detailed and ideal live video information.

Technical characteristics

The integrated intelligent pumping station adopts a modular combination structure, which integrates a variety of new technologies and new equipment, especially the application of a number of patented technologies, ensuring the advanced, reliable and practical characteristics of MPIS. As an integrated pumping station equipment, the integrated intelligent pumping station can achieve three unifications:

Unified technical standards The integrated intelligent pumping station is a standardized equipment produced in strict accordance with the national standard and MPIS professional enterprise standards. Each equipment is subjected to unified standard testing and inspection before leaving the factory.

Unified equipment brand The integrated intelligent pumping station is an integrated equipment integrating various technologies and products. From the main pumping unit to electrical control, intelligent protection, soft starter, frequency converter and metering, remote control and safety monitoring, etc. The Psillon brand ensures consistency from interface to protocol and specification.
