基于无刷直流电机的道闸驱动与控制系统

摘要

道闸常工作在恶劣的环境下，采用有刷直流电机或交流电机作为驱动电机需经常维护。为提高道闸系统的稳定性和寿命，设计了基于无刷直流电机的道闸驱动器和控制系统，详细阐述了基于无刷直流电机专用控制芯片MC33035的驱动器电路设计和基于STC89 C52单片机智能控制系统的硬件电路设计、功能与工作原理介绍和软件设计，并针对闸杆的调速、遇阻检测提出了具体解决方案。实践表明，系统能够实现无刷直流电机在道闸上的应用，简单稳定可靠。%Barrier Gates are often used in adverse working conditions , need to keep regular maintenance if drove by brush DC motor or AC motor .In order to improve the stability and service life of barrier gates system , the drive and control system of barrier gate based on BLDCM were designed .The barrier drive based on the BLDCM's special chip MC33035 and the intelligence control system based on microcontroller were designed detailly including circuit design , the introduce of function , the working principle and software design;Aiming at adjusting the speed of rallings and check whether meet resistance , the specific solutions were advanced .Practice shows that the system make use of BLDCM in barrier gates are executable .
