【摘要】：随着国家高等职业教育改革进一步深入，我国职业教育借鉴德国双元制职业教育模式，以校企深度融合为基础，以工学结合的人才培养模式改革为核心，进行课程设计。为了适应我国高职教育的发展，卓有成效地提升了学生的技能，培养高素质人才，提高高职学生的实际操作能力。本课题进行群控电梯设计，以满足高职教育《电气控制与PLC》课程对教学载体的需求。本课题以三菱PLC为技术平台，在电梯拖动系统，采用变频调速[17]，节能环保，效率高。为了提高电梯控制精度，选用旋转编码器进行轿厢位置检测，高速计数器统计脉冲个数，用程序进行数据处理。为了提高保护可靠性，采用模拟量输出重量传感器，经A/D数模转换送入PLC进行数据运算，由程序比较结果反应是否超重。为达到实训设备的实用性，电梯运行方式有单电梯运行、群控运行和检修运行三种方式。为实现三台电梯群控，采用CC-Link工业总线完成通信，实现主-从控制，主站控制器用三菱Q系列PLC，，从站用三菱FX2N，保证了教学实验设备技术的先进性、使用的安全性与方便性，使设备的控制系统具有现代先进水平，即增强了学生的实训兴趣，又提高了学生对实训内容的理解，同时增强学生的动手操作能力。通过需求分析，本课题主要完成内容包括：系统硬件设计、系统应用软件的应用、单电梯运行控制程序设计、三台电梯联合控制程序设计，现场总线通信设置等。群控电梯控制系统通过了全面测试，并在电气控制与PLC课程教学中应用，取得良好效果，达到预期目标。
[Abstract]:With the further deepening of the national higher vocational education reform, vocational education in our country draws lessons from the German dual-system vocational education model, based on the deep integration of schools and enterprises, and focuses on the reform of the talent training model combined with work and learning. In order to adapt to the development of higher vocational education in our country, it has effectively promoted the students' skills, trained high quality talents, and improved the practical operation ability of higher vocational students. In order to meet the higher vocational education "Electrical Control and PLC" course of teaching carrier demand. This topic takes Mitsubishi PLC as the technical platform, in the elevator drive system, uses the frequency conversion speed regulation [In order to improve the precision of elevator control, rotary encoder is used to detect the position of car, and high speed counter counts the number of pulses. In order to improve the reliability of the protection, the analog output weight sensor is used, and the data operation is carried out by A / D digital-analog conversion into PLC. In order to achieve the practicability of the training equipment, there are three modes of elevator operation: single elevator operation, group control operation and overhaul operation. In order to achieve the three elevator group control. The CC-Link industrial bus is used to complete the communication and realize master-slave control. The master station controller uses Mitsubishi Q series PLCand the slave station uses Mitsubishi FX2N, which ensures the advanced technology of teaching experiment equipment. The safety and convenience of using make the control system of the equipment have the modern advanced level, which not only enhance the students' interest in practical training, but also improve the students' understanding of the practical training content, and at the same time, enhance the students' practical operation ability. Through the requirement analysis, this topic mainly includes: system hardware design, system application software application, single elevator operation control program design, three elevators joint control program design. Field bus communication settings, etc. The group control elevator control system has passed the overall test, and has been applied in the teaching of electrical control and PLC course. It has achieved good results and achieved the expected goal.
