Control device of air-conveying spraying apparatus

Abstract

The objective of the invention is to provide a control device for an air-conveying spraying apparatus. The control device comprises an information collection module, a master control module, an execution module, a circuit protection module and an energy module, the operation of the whole machine is controlled through the control device, and the high-precision liquid medicine release is completed while information acquisition on fruit trees of an orchard is completed. During operation of the control device, an ultrasonic ranging sensor transmits the distance information of a vehicle body and the fruit trees in real time to a single chip microcomputer until an on-site distance conforms to a proper distance built in the single chip microcomputer, the spraying operation is started, and at themoment, an infrared target sensor starts scanning tree bodies of the fruit trees, and the tree body information is transmitted to the single chip microcomputer, and after the time delay, the single chip microcomputer sends high-low level signals to a steering engine driver and a fan speed governor, and finally a steering engine drives a spray head to swing to the corresponding angle and then the spray head is fixed, and meanwhile, the fan is started; and a control instruction is sent to a solid-state relay via the single chip microcomputer and then is transmitted to an electromagnetic valve, the electromagnetic valve opens liquid medicine and begins to convey, the quantitative spraying operation is started, and after the quantitative spraying operation is completed, the electromagnetic valve is closed, and each part keeps in-situ waiting for the next proper spraying time; and meanwhile, the ultrasonic ranging sensor starts to measure the next proper spraying distance and repeats the operation process. The control device is high in operation efficiency, good in safety performance and good in application prospect.

Description

technical field [0001] The invention belongs to the technical field of electronic control of agricultural machinery, and in particular relates to the design of a control device for spraying equipment. Background technique [0002] The control device of the traditional air-driven spraying equipment mainly adopts manual control, that is, the personnel work synchronously with the spraying equipment, and the stopping of the equipment and the spraying of the liquid medicine need to be manually adjusted by the personnel. The traditional sprayer control method has low control over the spraying accuracy, and causes a waste of human resources, and will also cause harm to the human body during the spraying process of the liquid medicine. Contents of the invention [0003] The object of the present invention is to provide a control device for air-driven spraying equipment, which includes: an information collection module, a main control module, an execution module, a circuit protecti...
