Embodiment

[0042] Such as figure 1 As shown, a water-saving irrigation method for litchi gardens based on wireless sensors as the core is characterized in that it includes sensor nodes and solenoid valve control nodes for information collection and information processing, gateway modules, human-computer interaction modules, and network server modules and website modules. The gateway module is electrically connected to the human-computer interaction module.

[0043] In this embodiment, the sensor node includes a core processor STM32F103C8T6, a wireless communication module CC2530, a power amplifier chip RFX2401, an air temperature and humidity sensor DHT22, a light intensity sensor GY-30, a soil moisture sensor TDR-3, a power supply module and a solar charging module . The sensor nodes are mounted on a steel tripod, which has three sizes, 0.5M, 1.0M and 1.5M. When measuring, the tripod is firmly placed above the soil of the litchi orchard to be tested, and then the TDR-3 soil moisture ...

Abstract

The invention discloses a wireless sensor network based water-saving litchi orchard irrigation control system and method. The system comprises multiple sensor nodes, multiple electromagnetic valve control nodes, a gateway module, a man-machine interaction module, a network server module, a site module and a mobile terminal module; each sensor node is connected with one electromagnetic valve control node; the gateway module is connected with the man-machine interaction module through a serial port and connected with the network server module through a mobile communication network, namely the internet; the network server module is connected with a mobile-phone client module through the internet; the network server module is connected with the site module through a database. Data transmission is performed through the wireless sensor network, GPRS (general packet radio service) and the internet, real-time performance and reliability in transmission are guaranteed, environment of litchi orchards is monitored in real time, intelligent level in irrigation is improved, and loss due to the fact that managers do not notice real-time growth of litchi in time to take correct measures is avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent control based on wireless sensor networks, in particular to a control system and method for water-saving irrigation of litchi gardens based on wireless sensor networks. Background technique [0002] The total planting area of ​​litchi in my country is 600000hm 2 , accounting for 75% of the world's total litchi planting area; the total output of litchi is 1,290,000 tons, accounting for 47.78% of the world's total litchi output. At present, due to the complex natural environment for fruit growth, orchard production management is mainly done manually, and the growth environment, growth and development, implementation of cultivation techniques, growth status, and prediction of plant diseases and insect pests of fruit trees are mainly judged by human experience. [0003] For a long time, the growth management of most litchi orchards has mainly relied on artificial irrigation, and the amount of irr...
