Rice precision irrigation measurement and control system based on wireless sensor network

Abstract

The invention provides a rice precision irrigation measurement and control system based on a wireless sensor network. The system comprises a farmland water level monitoring device, a base station device, a data server, a water pump controller, a water pump and a plurality of electromagnetic valves connected with the water pump, wherein the farmland water level monitoring device comprises a plurality of sensor nodes, and farmland water level information collected by the sensor nodes is transmitted to the data server by the base station device; the data server stores a farmland water level threshold that is set according to the requirements of rice cultivation, and the data server determines whether the water level of each farmland is within the set farmland water level threshold range according to the received farmland water level information, if the water level of a field block is lower than the lower limit of the farmland water level threshold, the data server sends a water pump turn-on instruction to the water pump controller to turn on the water pump and simultaneously sends a turn-on instruction to the electromagnetic valve corresponding to the field block to achieve the precision control of the farmland water level. According to the scheme of the invention, the precision irrigation control of rice can be implemented by using a wireless sensor network technology.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice precision irrigation measurement and control system based on a wireless sensor network. Background technique [0002] The existing conventional paddy field irrigation methods are "shallow irrigation and deep storage" or "shallow irrigation and middle storage", that is, shallow water irrigation is implemented, and precipitation is deep or middle storage. Through manual adjustment, the depth of the field water layer is controlled between the upper and lower suitable water layers. Its characteristic is that during the whole growth period of rice, except for the dryness once at the end of the tillering stage (falling into the water and drying the field), there is a water layer in the field at other stages. [0003] Due to the different heights of different fields, the current irrigation method is through a ditch, so that the water level of each field reaches the same le...

Problems solved by technology

[0003] Due to the different heights of different fields, the current irrigation method is through a ditch, so that the water level of each field reaches the same level, but the actual water level of the farmland cannot reach the desired water level due to the height of the field
