Intelligent variable medicine spraying machine based on prescription chart control

Abstract

The invention relates to an intelligent variable medicine spraying machine based on prescription chart control, belonging to the technical field of equipment for plant protection. The medicine spraying machine sprays medicines as required according to diseases, insects and grass difference information obtained by a GPS / GIS technology under the condition of uneven space distribution of the diseases, the insects and the grass. An intelligent control system works based on a prescription chart control mode and has automatic and manual working modes and the function of recording operation parameters of the machine in real time. When the medicine spraying machine carries out the field operation, the operation mode of the medicine spraying machine is conveniently selected through a working mode switching button. The intelligent control system acquires corresponding sensor signals according to the selected operation mode, outputs the required voltage signal to control the valve opening of an electric adjusting valve, thereby realizing variable medicine spraying operation; and operation parameter of a system is acquired in real time and recorded in an expanded data register of a central processing unit, thereby facilitating the analysis and the processing of later test data.

Description

technical field [0001] The invention relates to an intelligent variable spraying machine controlled based on a prescription map, which belongs to the technical field of plant protection machinery. technical background [0002] At present, the variable spraying machines sold in my country's plant protection machinery market are still mainly imported. Because the variable-variable spraying machines produced abroad use a series of high-tech such as electromechanical integration, automatic target spraying, low-volume spraying and full hydraulic drive, they have absolute advantages in variable control accuracy and operating efficiency. However, this type of spraying machine has high manufacturing costs and a wide operating width, and is mostly suitable for large-scale land operations, which is inconsistent with the current agricultural farming method of the household contract responsibility system in my country. Therefore, the domestically developed variable-variable spraying ma...
