Greenhouse crop automatic pesticide dripping system

Abstract

The invention discloses a greenhouse crop automatic pesticide dripping system and belongs to the technical field of agricultural irrigation. The system comprises a planting frame, an irrigation component and a control component, the planting frame and the control component are connected with the irrigation component, and the irrigation component provides fertilizer and water for crops in a greenhouse. The whole irrigation component is horizontal and vertical, thereby being attractive in appearance and convenient for subsequent maintenance; a soil humidity sensor paved in cultivation soil detects humidity at crop roots and transmits collected data to a single chip microcomputer through a first GSM (global system for mobile communications) chip and a soil humidity collection module, the single chip microcomputer adjusts flow of a branched pipe in the irrigation component through data processing, the flow of the branched pipe is detected by a flow sensor, collected data are transmitted tothe single chip microcomputer through a second GSM chip and a flow collection module, and the single chip microcomputer controls the branched pipe through an electric control valve; a manual adjusting valve supportive of manual flow control is mounted on the branched pipe, so that the circumstance that the branched pipe continuously feeds liquid during power-off is avoided, and the system is highin applicability.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an automatic dripping system for greenhouse crops. Background technique [0002] The automatic drip irrigation technology is based on comparing the soil moisture value collected by the humidity sensor embedded in the plant soil with the soil moisture set value required for plant growth in the control program. When the collected soil moisture value is less than the set value, it will automatically open The water pump and solenoid valve drip-irrigate the plants. When the collected soil moisture value is greater than the set value, the water pump and solenoid valve are automatically turned off. The whole process does not require direct human participation, which improves the efficiency of planting roof watering and greatly saves manpower and maintenance costs. [0003] In the practical application of automatic drip irrigation technology, the soil moisture value is of...

AI Technical Summary

Problems solved by technology

[0003] In the practical application of automatic drip irrigation technology, the soil moisture value is often within the set range, and the system shows that it is running well, but the drip irrigation pipe network has problems such as pipe bending or blockage, which will lead to long-term lack of plants and death, especially Especially in summer, plants often die due to lack of water. When the system fails, the existing drip irrigation pipe network layout is unreasonable, and the faulty area cannot be quickly found. It can only be checked one by one. It takes a long time to solve the fault, that is, maintenance Inconvenient, in the event of a power outage or other unexpected situations, the system will also drip liquid to the soil, which has poor practical adaptability
