【摘要】：电梯是日常生活中常见的一种电气设备,出现在商场、机场和住宅楼等众多场所,是现代建筑的重要组成部分。随着半导体和电机制造技术的不断发展,电梯技术也经历了多次跨越式的发展。本文根据当前电梯技术的最新进展以及对特种设备安全性的全面分析,基于永磁同步电机技术,设计了一种新型的曳引机驱动与控制系统。本文从电梯的基本原理出发,将电梯驱动控制系统分为控制系统、曳引系统、驱动系统和电气安全保护系统四个模块。根据各个模块的不同需求,细致分析其在整个系统中的作用,提出完整的设计方案,并根据设计方案对其中关键部件的技术参数进行理论计算,以期完成诸如曳引机、控制芯片及传感器等部件的选型。其中,控制系统采用DSP TMS320F28335作为核心控制芯片,通过其分析各个传感器信号,控制驱动系统,使曳引机按照设定程序进行工作。曳引系统采用的是永磁同步电机。永磁同步电机具有体积小、控制性能优良且效率较高等诸多优点,目前得到了广泛应用。驱动系统采用智能功率模块作为核心器件,按照控制系统的输出信号驱动曳引机系统,并且将故障信号反馈至电气安全保护系统,保证电梯运行的稳定可靠。电气安全保护系统采用CPLDEPM3128A作为核心控制器,由其综合控制电梯的电气保护系统,实时分析电梯系统各个模块反馈的故障信息,及时对故障做出反应,防止出现意外。在完成各个模块设计的基础上,按照器件的选型结果及电磁兼容要求设计并制作各个模块的电路板,在电气设备的标准安装规范指导下进行整体安装。最后,全面分析系统整体的实际需求,设计核心控制电路和安全保护电路的基本软件架构：根据电梯的实际运行模式,对永磁同步电机采用空间矢量脉宽调制的控制方法,编写DSP程序；针对系统的安全保护需求,编写CPLD控制程序。测试结果表明,电梯控制系统、驱动系统及电气安全保护系统均能正常运行,达到设计的预期要求。
[Abstract]:Elevator is a common electrical equipment in daily life. It appears in many places such as shopping malls, airports and residential buildings. It is an important part of modern architecture.With the continuous development of semiconductor and motor manufacturing technology, elevator technology has experienced many leaps and bounds.According to the latest development of elevator technology and the comprehensive analysis of the safety of special equipment, a new traction drive and control system is designed based on permanent magnet synchronous motor (PMSM) technology.Based on the basic principle of elevator, the elevator drive control system is divided into four modules: control system, traction system, driving system and electrical safety protection system.According to the different requirements of each module, the function of each module in the whole system is analyzed in detail, and a complete design scheme is put forward. According to the design scheme, the technical parameters of the key components are calculated theoretically in order to complete such as tracer.Control chip and sensor and other components selection.The control system uses DSP TMS320F28335 as the core control chip, through which the signal of each sensor is analyzed and the drive system is controlled, so that the tracer can work according to the set program.The traction system adopts permanent magnet synchronous motor.Permanent magnet synchronous motor (PMSM) has been widely used for its advantages of small size, good control performance and high efficiency.The driving system uses intelligent power module as the core device, drives the tracer system according to the output signal of the control system, and feeds back the fault signal to the electrical safety protection system to ensure the stability and reliability of the elevator operation.The electrical safety protection system adopts CPLDEPM3128A as the core controller, which synthetically controls the electrical protection system of the elevator, analyzes the fault information feedback of every module of the elevator system in real time, makes timely response to the fault and prevents the accident.On the basis of the design of each module, the circuit board of each module is designed and made according to the result of device selection and the requirements of EMC, and the whole installation is carried out under the guidance of the standard installation specification of electrical equipment.Finally, the actual demand of the whole system is analyzed, and the basic software architecture of the core control circuit and the security protection circuit is designed. According to the actual operation mode of the elevator, the space vector pulse width modulation control method is used to control the permanent magnet synchronous motor (PMSM).Write the DSP program and write the CPLD control program for the security protection requirements of the system.The test results show that the elevator control system, the drive system and the electrical safety protection system can all operate normally, which can meet the expected requirements of the design.
