摘要
文中设计了一种基于MC9S12单片机的智能车数据远程传输系统。该系统以Nordic公司生产的2.4GHz频段射频芯片NRF24L01作为数据无线收发芯片,以Freescale单片机MC9S12为控制单元,采用交互式"主从"结构,实现了运动状态下模型车的相关参数和运动轨迹的远程传输和控制。实际运行结果表明,所设计的模型车数据传输准确率高、行驶速度快、易于控制。
A remote data transmission system for intelligent vehicle with MC9S12 MCU was designed in this paper. In this system, as the core component, the chip NRF24L01 with 2.4 GHz radio frequency was designed as a wireless transceiver,, made by Nordic company. The Freescale＇s MC9S12 MCU was designed as the control unit. The structure of the system is principal and subordinate and the mode of data transmission is interactive. With the system designed in the paper, the relative parameters and the motion trajectory of the intelligent vehicle can be transmitted and controlled remotely when intelligent vehicle was in running state. The practical result shows that, the designed transmission system for intelligent vehicle is with high running velocity, transmitting accuracy, and feasible control performance.
