Problems solved by technology
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.
