Fertilizer box remaining amount monitoring system and monitoring method

Abstract

The invention relates to a fertilizer box remaining amount monitoring system and monitoring method. The fertilizer box remaining amount monitoring system comprises a fertilizer applicator, WHEREIN thefertilizer applicator comprises a fertilizer box, a fertilizer discharging mechanism, a cab, an electric control system and main control equipment, wherein the electric control system comprises a laser distance measuring sensor array used for monitoring the information of the distance between the fertilizer in the fertilizer box and the inner side of the top part of the fertilizer box in real time and sending the information to a controller, an opening degree detection sensor used for detecting an opening degree of a fertilizer discharging shaft in the fertilizer discharging mechanism and sending the opening degree to the controller, a rotating speed detection sensor used for detecting a rotating speed of the fertilizer discharging shaft in the fertilizer discharging mechanism and sendingthe rotating speed to the controller, the controller used for processing all the received information and sending the information to the main control equipment, and a 5 V power supply used for supplying power to each sensor and the controller; and the main control equipment is used for calculating the remaining amount of the fertilizer box, predicting the fertilization duration and giving emptying early warning. The fertilizer box remaining amount monitoring system and the monitoring method can be widely applied to the field of fertilizer box remaining amount monitoring.

Description

technical field [0001] The invention relates to the fields of intelligent agricultural machinery, unmanned fertilizer applicators, and granular chemical fertilizer storage and transportation equipment, and in particular to a fertilizer tank residual monitoring system and monitoring method. Background technique [0002] The use of chemical fertilizers contributes significantly to increasing the yield of agricultural production. At present, the use of chemical fertilizers in China is increasing year by year, doubling in 25 years. Although the application of chemical fertilizers is large, the utilization rate of chemical fertilizers is less than 40%. Unused chemical fertilizers enter the soil, water body and atmosphere through ecological cycles, causing pollution to the environment and also causing economic losses. [0003] Variable fertilization technology can reduce the application of chemical fertilizers and reduce the impact of chemical fertilizers on the environment. The...
