Agricultural greenhouse automatic irrigation and monitoring system based on wireless networking

Abstract

The invention discloses an agricultural greenhouse automatic irrigation and monitoring system based on wireless networking. The system comprises an acquisition system and a water storage tank, one side of the water storage tank is connected with a water pump through a check valve, the water outlet end of the water pump is provided with a filtering device, and the upper end of the filtering device is connected with an irrigation main pipe through a bending pipe. An electric butterfly valve is arranged at the water inlet end of the irrigation main pipe, a pipeline pressure sensor and a flow meter are sequentially arranged on the portion, on one side of the electric butterfly valve, of the irrigation main pipe, the irrigation main pipe extends into a greenhouse, the acquisition system is connected to a database through an internal data line, and the database is connected to a CC2530SOC through an internal data line. The signal output end of the CC2530SOC is wirelessly transmitted to a mobile terminal through a wireless networking module. According to the system, the wireless networking module realizes wireless signal transmission, and the system is reasonable in structural design, convenient to use, mount and maintain, low in investment and transformation cost, simple and convenient to set and control, and suitable for popularization and application as an intelligent agricultural irrigation system.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouse irrigation and monitoring, in particular to an agricultural greenhouse automatic irrigation and monitoring system based on wireless networking. Background technique [0002] With the continuous improvement of living standards, people's demand for green food is increasing. Agricultural greenhouses are an important way to obtain green food all year round. Farmland irrigation plays an extremely important role in the production of green food. The quality and efficiency of irrigation greatly affect the life and income of farmers. At present, many places still use high-power water pumps to irrigate manually, which not only wastes water resources, but also has low irrigation efficiency, and cannot intelligently monitor and control the irrigation system online. Temperature and soil humidity play a decisive role in the growth of crops in greenhouses. At present, many greenhouses still use ...

Problems solved by technology

At present, many places still use high-power water pumps to irrigate manually, which not only wastes water resources, but also has low irrigation efficiency, and cannot intelligently monitor and control the irrigation system online. Temperature and soil humidity play a decisive role in the growth of crops in greenhouses. At present, many greenhouses still use traditional monitoring methods, and their shortcomings are very obvious, such as cumbersome wiring, high cost, troublesome maintenance, and the need for real-time guards. Wireless networking has the advantages of It has the advantages of wide range, strong equipment carrying capacity, high safety performance, good stability, and low power consumption, and integrates a number of technologies, including distributed information processing technology, sensor technology, wireless communication technology and embedded computing technology, through mutual Collaborate to complete real-time perception, detection and collection of various target information, and analyze and process the obtained data. Therefore, it is urgent to design a wireless monitoring system for various devices in the greenhouse based on wireless networking
