Arm-based Remote Control System Of Rotary Tillers

As a similar small machine, Micro-farming Machine has been widely used in the hills and mountains, accounting for a large area of China, a large agricultural country. With the deepening of rural reform agriculture, the continuous adjustment of planting structure, the declining of field crop area, continuous increasing of the area of economic crops, species tending to grow more and more scale. It gradually became the focus that how to reduce the labor intensity of farming and realize automatically.Combined with increasingly sophisticated remote control technology, the main purpose of this project is to develop low-cost, high performance, and multi-function remote control Micro-farming Machines.Based on technology theoretical of the Micro-farming Machine remote control system, this paper has detailed the related knowledge and system requirements analysis and demonstration program, planned a general design ideas of the system. Finally, It has determined to use the low-power wireless technology for wireless transmission and high-performance ARM microcontroller LPC2132 for the master chip, give the functions, hardware and software structure, communication protocols of the each system unit, use modular architecture to simplify system designing, lay the foundation for the later chapters.The paper has designed the system hardware circuit. In order to achieve the hardware, it has selected ARM microprocessor LPC2132 as a core controlling chip, used wireless transmission module nRF905 to send and receive data, real-timely displayed system running status by liquid crystal display module LCD12864.This thesis has used ADS1.2 as software development environment, written in a modular fashion with C language, given the main program, the menu program, communication program, LCD procedures and the interrupt program flow diagram of the remote control system.In addition, in order to fully enhance the system sTab.ility, the paper has also detailed the system software and hardware anti-jamming design.Experimental tests have verified that the system, reliable, working properly, easily controlled and displayed timely, has met the system performance requirements. Thereby, it has reduced the labor intensity of human cultivation, and achieved the goal of the Micro-farming Machine for farming automatically.
