为了提高施肥的精度,实现施肥过程的自动化,设计了一款新的激光扫描定位PLC 自动化控制的精密施肥机器人. 采用PID调节的方式设计了机器人的PLC控制闭环系统,以激光扫描得到的施肥深度为依据,通过逻辑判断调整变速器的传动比,实现不同深度的施肥效果,提高了施肥作业的智能化水平及施肥的精度. 为了验证装置的有效性和可靠性,在田间对精密施肥机器人进行了测试. 田间测试发现:对于施肥长度为50 m的作业,所设计的施肥机器人的施肥时间明显降低,大大提高了作业效率,施肥合格率明显高于传统的施肥机器人,可在精密化施肥和自动化农业生产中进行推广.%In order to improve fertilizing precision , fertilization process automation , design a new laser scanning and po-sitioning of the PLC automatic control of precision fertilization robot .Using PID methods to adjust the design of the robot PLC closed-loop control system , the system of fertilization depth by laser scanning as the basis , determine the transmis-sion ratio through the transmission adjustment logic , achieve different depth of fertilization effect , improve the intelligent level of fertilization , the effectiveness of high precision fertilization device in order to verify in the field of precision and reliability, fertilization robot was tested by field test , found that, for the fertilization of length 50m fertilization, fertiliza-tion robot designed in this paper the fertilization time is significantly reduced , thereby greatly improving the work efficien-cy , the qualified rate of fertilization was higher than that of the traditional fertilization robot , thus greatly improve the qualified rate of fertilization , which can be used in precision fertilization and automation in agricultural production .
