Problems solved by technology

Due to the imperfection of spraying machinery and spraying technology, artificial spraying can easily lead to pesticide poisoning of operators, and often the spraying is uneven, and the pesticides cannot be used rationally.
On the one hand, the uneven spraying of pesticides causes the waste of pesticides, and on the other hand, it causes serious harm to the environment, agricultural products and human health

Embodiment 1

[0021] see figure 1 , a fully automatic pesticide precise variable spraying control system, including a single-chip microcomputer and a display connected to the single-chip microcomputer, a keyboard, a D / A converter a, a D / A converter a, a pressure sensor, a flow sensor, a D / A converter a and a controller a. The booster pump and the medicine storage tank are connected in sequence, and the D / A converter b is connected with the controller b and the solenoid valve in sequence. The solenoid valve, pressure sensor and flow sensor are located inside the spray head.

[0022] In the present invention, the display and the keyboard form a human-computer interaction interface. The setting of parameters and the control of the system can be realized through the human-computer interaction interface. The parameter setting includes the setting of pesticide spraying amount and nozzle pressure. By setting the pressure of the nozzle, the agriculture can be sprayed to different positions, and b...

Embodiment 2

[0024] In this embodiment, on the basis of Embodiment 1, in order to better realize the present invention, the model of the single-chip microcomputer is an ATMEGA32 single-chip microcomputer. ATMEGA32 microcontroller has the following advantages: (1) High performance, low power consumption, high cost performance; (2) Good storage performance; (3) Power-down protection function. By adopting the ATMEGA32 single-chip microcomputer, not only the manufacturing cost of the present invention can be effectively reduced, but also the storage performance of the single-chip microcomputer can be guaranteed and data loss caused by power failure can be avoided. Other parts of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Embodiment 3

[0026] In this embodiment, on the basis of the above embodiments, in order to better realize the present invention, the flow sensor is connected to the single-chip microcomputer through an optical coupler. Since the flow sensor is connected to the microcontroller through an optocoupler, during data transmission, the flow sensor converts the electrical signal representing the flow into an optical signal for data transmission. The transmission process eliminates the influence of the electromagnetic field on the electrical signal of the flow sensor and transmits it to the microcontroller. The data is more accurate, and the system's ability to resist electromagnetic field interference is stronger. Other parts of this embodiment are the same as those of the foregoing embodiment, and will not be repeated here.

Abstract

The invention discloses a full-automatic accurate pesticide variable-flow spray control system. The full-automatic accurate pesticide variable-flow spray control system comprises a single-chip microcomputer, a displayer, a keyboard, a D / A converter a, a D / A converter b, a pressure sensor and a flow sensor, wherein the displayer, the keyboard, the D / A converter a, the D / A converter b, the pressure sensor and the flow sensor are connected with the single-chip microcomputer, the D / A converter a is connected with a controller a, a pressure pump and a pesticide storage box in sequence, the D / A converter b is connected with a controller b and an electromagnetic valve in sequence, and the electromagnetic valve, the pressure sensor and the flow sensor are located in a spray head. The full-automatic accurate pesticide variable-flow spray control system is free of manual operation and capable of achieving full-automatic spray and avoiding pesticide poisoning which is likely to happen to an operator during manual spraying; pesticide can be accurately and evenly sprayed to a farmland, and pesticide is fully and reasonably used; the harm to the environment, agricultural products and human health is greatly reduced.

Description

technical field [0001] The invention relates to the field of pesticide spraying, in particular to a fully automatic precise variable spraying control system for pesticides. Background technique [0002] The history of China's agricultural development is also a history of constant struggle against various agricultural diseases and insect pests. In the history of the Republic, agricultural diseases, insect pests and weeds have ruthlessly ravaged many times. At present, three methods are mainly used to prevent diseases, insect pests and weeds in farmland: agroecological control, biological control and chemical control. Due to the slow effect of agroecological control and biological control, the control effect is not ideal, and the cost is not easy to control, so most of the farmland diseases, insect pests and weeds can only be controlled and solved in time by relying on chemical control. At present, most of the farmlands in our country are sprayed manually. Due to the imper...
