Problems solved by technology

[0002] my country's agriculture is characterized by the variability of the external environment, the diversity of the land environment, and the complexity of the geological structure. It is difficult for ordinary instruments and equipment to achieve economical and accurate real-time monitoring. One feature, water-saving irrigation should also take into account the requirements for saving labor and energy, so as to effectively reduce the cost of agricultural production
The current agricultural production has its diversity, and different crops have different water requirements, and most of the existing water-saving irrigation is not compatible with the actual needs of crops and the actual conditions of the planting environment.
[0003] At present, wireless technology is widely used in agriculture, but most of them are star topology applications with base stations, not wireless sensor networks in the true sense

Embodiment Construction

[0029] The gateway is connected to the local area network or the Internet through a wired or wireless network, and the gateway and WSNNode sensor nodes are connected through wireless communication. The gateway transmits the data collected from the sensor nodes to the management center. The management center obtains the information of the area that needs to be irrigated through data processing, calculation and analysis, and feeds this information back to a specific gateway, which controls the irrigation equipment it controls. Irrigate the designated area, so as to realize the closed-loop control of irrigation in the planting area.

[0030] The schematic diagram of the wireless sensor node system is composed of a central processing unit, a memory, a wireless communication module supporting the 802.15.4 protocol, and a sensor board. The processor uses a low-power microprocessor chip ATmega128, the radio frequency part uses an XS110 chip, and the extended storage 512KB low-power F...

Abstract

The invention discloses an agriculture water saving irrigation system based on wireless sensor network, composed of wireless sensor node, gateway, management center and irrigation device, also discloses an agriculture water saving irrigation system based on wireless sensor network, using wireless sensor node and gateway, the moisture state of plant is monitored at real time. The monitoring data is processed by the computer of the management center and a rational and effective water saving irrigation project is arranged based on different features of plant. Due to the expansibility of the said device, the said system is comprehensively utilized with the other information device and is able to provide informative, complex and substantial service.

Description

technical field [0001] The invention relates to the field of agricultural water-saving irrigation and sensor monitoring, in particular to an agricultural water-saving irrigation system and method based on a wireless sensor network. Background technique [0002] my country's agriculture is characterized by the variability of the external environment, the diversity of the land environment, and the complexity of the geological structure. It is difficult for ordinary instruments and equipment to achieve economical and accurate real-time monitoring. One feature, water-saving irrigation should also take into account the requirements of saving labor and energy, so as to effectively reduce the cost of agricultural production. The current agricultural production has its diversity, and different crops have different requirements for water. Most of the existing water-saving irrigation is not compatible with the actual needs of the crops and the actual conditions of the planting environm...
