Design of agricultural water-saving irrigation control system based on IOT

Background and Aims

China isa big agriculturalc

ountry

China’s agricultural water c onsumpti on stillaccounts for 7 0 percent of the

country’s total water consumption, a n d in the country’s water consumption,

agricultural evaporation of water c onsumpti on accounts for about 9 0 percent.

S o m e countries ha v e adopt ed a d v a n c e d water-saving irrigation systems.

S o w e wa n t to achieve the purpose of water-saving irrigation a n d automation of

water-savingirrigation.

Control principle

  1. Eq u i pme n t controlfunction

Th e equipment control function includes

the individual control ofe

a c h solenoid valve

a n d water p u m p in the field a n d the rotation

control of the solenoid valve. In the c a s e of

individual control, farmers c a n individually

o p e n or close e a c h device o n the monitoring

screen.

Control principle

  1. Alarm function

The alarm function ismainly carried out for

important operations a n d analog quantity

exceeding limits.

According to the conditions of the on- site

computer, the alarm m e t h o d c a n ha v e two

methods: s o u n d a n d light a n d S M S . Itisnecessary

to configure the corresponding speaker a n d S M S

sending mo d u l e inthe p u m p r o o m monitoring

system.

Control principle

  1. User m a n a g e m e n t f

unction

The users of the field p u m p hous e m a n a g e m e n t s y st em

mainly include farmers w h o operate the s y st em a n d maintenance

personnel for corresponding parameter settings. Different users get

different permissions by logging inwith user n a m e s a n d passwords.Control principle

  1. Data uploadfunction

The on-site monitoring station isonly the bo tt om monitoring s y st em of the

entire system. Itisthe bo tt om data acquisition system. For the upper

m a n a g e m e n t system, italso includes the function of uploading data to the

monitoring system.

FINDING

Of course s y st em still exists o m e shortcomings, such as scalability,

automatic irrigation equipment set u p s o m e expensive still,s y st em operation is

not simple, etc., but anywa y , w e willtry our best to slowly quantitative solve these

problems, willnot reduce to a mi n imum.

s o l v ti o n :

1.we make an operate document for the system ,and find people to train new one

2.To save cost, we can replace Alibaba platform with free IOT platform

3.Add mobile terminal control implementation function blockConclution

With this s y st em,we c a n according to m a n a g e s y st em control the

water u s e a n d u s e p h o n e t o a l a rm,t h a n it ma k e t h e wa t e r u s e i n

time , u s e i n ri g h t amo u n t。

Thus, wa st e water irrigation isn o longer there are so ma n y , c a n save about

forty percent of irrigation water from the data, farmers irrigation labor costs by u p to

8 5 %,

The system is mainly through the sensor and IOT platform to achieve effective control of

water use, through the sensor sensing soil moisture, early warning watering area, and the

amount of watering. Through the computer system to control the user’s water demand,

water authority and water consumption, also through the mobile phone to receive data,

early warning and control water pump irrigation
