Agricultural chemical application monitoring and accurate flow rate control device and method

Abstract

The invention relates to an agricultural chemical application monitoring and accurate flow rate control device and method. The device comprises a chemical mixing device, a flow rate meter, a nozzle, acontroller and an infrared remote sensing detector, on-spot preparing and using of agricultural chemical is achieved by the chemical mixing device, the agricultural chemical is sprayed by passing through a primary pipeline to reach the nozzle, remote sensing images of a field are detected by the infrared remote sensing detector, and a corresponding application prescription map and an applicationstrategy are generated after data analysis processing is conducted; agricultural chemical spraying is controlled by the controller according to the application prescription map and the application strategy, the application concentration is adjusted by controlling a water pump and a chemical filling pump, application situation is monitored in real time according to signals transmitted by a camera,an ultrasound radar, the flow meter and a velocity sensor to adjust the application concentration and the flow rate, and therefore accurate application and flow rate control can be achieved. Accordingto the device, computation of the concentration and amount of the chemical can be conducted according to disease and pest situation of the field, feedback is conducted in real time, accurate application is conducted to improve the utilization rate of the agricultural chemical, and agricultural residue and waste caused by blindly application are prevented.

Description

technical field [0001] The invention relates to the field of pesticide application, in particular to a pesticide application monitoring and precise flow control device and method. Background technique [0002] Plant management operations include propagation and planting, plastic pruning, pest control, soil, fertilizer and water management, etc. Among all management links, pest control is the most time-consuming and very important operation item, and its workload accounts for about 10% of the total plant management workload. About 30%. According to survey statistics, plants need to spray pesticides 8 to 16 times during the growth period of one year. The traditional method is that the pesticide applicators set the concentration according to observation, and then spray on a large area. After spraying, about 50 to 70% of the pesticides are sprayed. Landing in the soil and the surrounding environment, blind application of pesticides results in serious waste of pesticides and ser...

Problems solved by technology

According to survey statistics, plants need to spray pesticides 8 to 16 times during the growth period of a year. The traditional method is that the pesticide applicators set the concentration according to observation, and then spray on a large area. After spraying, about 50 to 70% of the pesticides Landing in the soil and the surrounding environment, blind application of pesticides causes serious waste of pesticides and serious environmental pollution

[0003] Secondly, the fixed pesticide ratio and large-scale spraying cannot be adapted to local conditions. Some parts with serious pests and diseases will not be controlled due to insufficient spraying concentration, and areas without pests and diseases will cause pesticide residues due to excessive spraying, or cause large-scale poisoning and production reduction of crops
