ARM-based variable spray control system

Abstract

The invention provides an ARM-based variable spray control system, and belongs to the technical field of variable spray control. The ARM-based variable spray control system is mainly composed of a touch screen, a pressure sensor, a flow sensor, a speed sensor, an ARM processor, a display screen, a data memory, a record book, a signal converter and an electric regulating valve, wherein the touch screen, the pressure sensor, the flow sensor and the speed sensor are connected with the ARM processor, and are disposed at an input end of the ARM processor, the display screen, the data memory and the signal converter are disposed at an output end of the ARM processor, the data memory is connected with the record book, and the electric regulating valve is connected with the signal converter. The ARM-based variable spray control system provided by the invention controls the spray amount of a spray head by using prescription decision data as standard, so as to realize variable spray operation, and the requirements for the professional skills of operators are low, so that the ARM-based variable spray control system is more suitable for the current situation of development of agricultural intelligent equipment in China.

Description

technical field [0001] The invention relates to an ARM-based variable spraying control system and belongs to the technical field of variable spraying control. Background technique [0002] When multiple nozzles of the spraying machine operate at the same time, the system structure is complicated, and the workload of the central processor to collect and process signals increases, and the cost of intelligent control increases. The central processor of the variable spraying control system based on the prescription map is mostly 51 series single-chip microcomputer. However, since the 51 series single-chip microcomputer is an 8-bit computer, no matter how the peripheral equipment is expanded, its performance, logic operation speed, memory, and communication capabilities are still limited by the 8-bit computer, which affects the control accuracy and functional design of this type of system. The invention develops an ARM-based variable spraying control system. Contents of the in...
