【摘要】：當(dāng)前,國(guó)內(nèi)外農(nóng)用系統(tǒng)正向著高效、精準(zhǔn)、電子化的方向發(fā)展,但國(guó)內(nèi)大部分農(nóng)田打藥機(jī)混藥系統(tǒng)為預(yù)混式,即混藥人員按照比例將農(nóng)藥與水裝入打藥箱中,均勻攪拌。在人工手動(dòng)混合的操作方式下,農(nóng)藥直接或間接地接觸到人體,這種情況嚴(yán)重影響著身體健康,同時(shí)空氣室、藥箱與農(nóng)藥的接觸會(huì)產(chǎn)生嚴(yán)重的腐蝕,此類(lèi)原因?qū)е抡麢C(jī)壽命降低,另外,在藥液的清洗過(guò)程中人體與藥液會(huì)長(zhǎng)時(shí)間接觸,容易帶來(lái)致癌風(fēng)險(xiǎn),環(huán)境污染也會(huì)因?yàn)闅埓孓r(nóng)藥的處理而變得更加嚴(yán)重。為了避免先前混藥方式給環(huán)境和非目標(biāo)生物帶來(lái)的污染、施藥人員的健康威脅以及噴藥機(jī)械的壽命縮短,液藥與水的在線(xiàn)混合、混藥與噴藥器械的自動(dòng)化操作方式是現(xiàn)代農(nóng)業(yè)技術(shù)研究的重要方向。本文研究和開(kāi)發(fā)了一款農(nóng)業(yè)混藥系統(tǒng)。首先依據(jù)系統(tǒng)要求選擇相關(guān)的硬件,對(duì)WiFi模塊進(jìn)行系統(tǒng)刷入和改裝,驗(yàn)證流量計(jì)的工作方式和穩(wěn)定性,設(shè)計(jì)繼電器模塊,隨后根據(jù)硬件的控制方式對(duì)單片機(jī)程序進(jìn)行設(shè)計(jì),使其接收到控制信息后便改變外圍硬件的工作狀態(tài),處理傳感器的反饋指令,此外,對(duì)基于Android操作系統(tǒng)的上位機(jī)軟件進(jìn)行開(kāi)發(fā),為用戶(hù)提供可視化的應(yīng)用界面和便捷的操作方式。安卓設(shè)備與WiFi模塊通過(guò)Socket通信進(jìn)行控制信息的傳輸,WiFi模塊與單片機(jī)串口連接通信。整個(gè)設(shè)計(jì)完成了藥水分離下的實(shí)時(shí)混合、實(shí)時(shí)監(jiān)控和對(duì)噴幅的控制。最后對(duì)系統(tǒng)WiFi信號(hào)進(jìn)行采集和處理,使信號(hào)更加穩(wěn)定,通過(guò)Fluent對(duì)混藥器運(yùn)作時(shí)流體的參數(shù)進(jìn)行仿真對(duì)比,對(duì)系統(tǒng)進(jìn)行優(yōu)化,選擇最優(yōu)設(shè)備,使系統(tǒng)實(shí)現(xiàn)無(wú)人化和機(jī)器人化的發(fā)展目標(biāo),適應(yīng)農(nóng)業(yè)發(fā)展的新形式。
[Abstract]:At present, agricultural systems at home and abroad are developing in the direction of high efficiency, precision and electronization. However, most of the mixing system of agricultural drug dispenser in China is premixed, that is, the pesticide and water are put into the dispenser in proportion by the mixers. In manual mixing, pesticides directly or indirectly contact the human body, which seriously affects the health of the body. At the same time, the contact of air chamber, medicine box and pesticide will cause serious corrosion. This kind of reason causes the whole machine life to reduce, in addition, in the medicine liquid cleaning process the human body and the medicine liquid will contact for a long time, easy to bring the carcinogenic risk. Environmental pollution is also aggravated by the treatment of residual pesticides. In order to avoid the pollution of the environment and non-target organisms caused by the previous mixing methods, the health threat of the applicator and the life span of the spraying machinery are shortened. On-line mixing of liquid and water. The automatic operation mode of mixing and spraying equipment is an important direction of modern agricultural technology research. This paper studies and develops an agricultural mixing system. Firstly, according to the system requirements, select the related hardware. The WiFi module is brushed in and refitted to verify the working mode and stability of the Flowmeter, and the relay module is designed, and then the single chip microcomputer program is designed according to the control mode of the hardware. After receiving the control information, it changes the working state of the peripheral hardware and processes the feedback instructions of the sensor. In addition, the host computer software based on the Android operating system is developed. Provide users with visual application interface and convenient mode of operation. Android devices and WiFi module through Socket communication control information transmission. WiFi module and MCU serial port communication. The whole design completed the real-time mixing, real-time monitoring and spraying control under the separation of potions. Finally, the system WiFi signal acquisition and processing. To make the signal more stable, the fluid parameters of the mixer are simulated and compared by Fluent, the system is optimized and the optimal equipment is selected, so that the system can realize the goal of dehumanization and robotization. To adapt to the new forms of agricultural development.
