摘　　要：设计并实现了一种基于FPGA和SIM908模块的远程定位运动系统.在SOPC Builder中构建以CPU、存储器、定时器、Avalon总线、UART为核心的NIOS处理器,编程实现对SIM908模块GPS数据的接收以及控制指令的解析与处理,并根据指令计算电机驱动模块控制参数,驱动电机使该装置按照给定路径行驶.系统使用软硬件协同设计技术实现,控制命令解析由软件编程实现,而电机驱动与调整由FPGA上逻辑电路实现,详细阐述了软硬件的设计过程.实验结果表明该控制器能通过解析控制命令完成给定路径行驶、实现定位.The paper designs and implements a remote controller for motion positioning device based on FPGA and SIM908 module. The design builds a NIOS processor consist ofNIOS II CPU, memory, the timer, Avalon bus, UARTs. The processor receives GPS data of SIM908 module, analyses and processes data of control instructions, calculates the control parameters for the motor drive module and drives the device along a given path. The system uses hardware and software codesign technology. Control instructions are parsed by software, but the driver and adjustment of motor are implemented by the logic circuit. The paper introduces the design and implementation process of the hardware and software in detail. Experimental results show that the controller can complete a given path under the control of control instructions, and realize positioning within the acceptable error.
