【摘要】：电动机作为拖动系统中的重要组成部分,在国民经济中占有举足轻重的地位。它的使用几乎渗透到了各行各业,是工业、农业和国防建设及人民生活正常进行的重要保证,因而确保电动机的正常运行就显得十分重要。而在实际使用过程中,由于普通的电机综合保护控制器的局限性,很多情况下电机不能得到有效保护,时常容易造成电机烧毁甚至引发重大安全事故。全国每年因电动机烧毁消耗大量的电量、维修损耗,而因停工停产所造成的损失更是一个无法估量的巨大数目。因此做好电动机的保护具有节能显著、提高生产效率和经济效益及保证安全生产的重要意义。本文主要工作内容如下:1.根据低压电机控制器的发展现状和基本原理,分析确定了基于STM32F105的硬件架构,并设计了控制器各模块的硬件电路。2.移植嵌入式实时操作系统FreeRTOS至STM32F105,并进行移植验证和性能测试。在此基础上,划分各个功能任务并设计各模块程序,完成软件设计。3.根据上下位机信息交互的特点,制定可靠有效的数据通信协议Modbus,并使用VC++编写上位机界面测试程序,实现了PC和控制器的RS485通信。4.对控制器进行软硬件联合调试,并模拟各种实际故障,对控制器的保护特性进行测试。测试结果表明,本控制器软硬件设计合理,能很好的对低压电机的各种故障进行有效保护,性能满足实际应用需求。
[Abstract]:As an important part of the drive system, motor plays an important role in the national economy. Its use almost permeates all kinds of industries and is an important guarantee for the construction of industry, agriculture and national defense and the normal life of the people, so it is very important to ensure the normal operation of the motor. In the actual use process, due to the limitations of the ordinary motor integrated protection controller, the motor can not be effectively protected in many cases, which is often easy to cause motor burn-out and even lead to major safety accidents. Every year, the whole country consumes a lot of electricity and maintenance because of the burning of motor, and the loss caused by shutdown is an inestimable and huge number. Therefore, the protection of motor is of great significance to save energy, improve production efficiency and economic benefit and ensure safety in production. The main contents of this paper are as follows: 1. According to the development status and basic principle of low voltage motor controller, the hardware architecture based on STM32F105 is analyzed and determined, and the hardware circuit of each module of the controller is designed. 2. The embedded real-time operating system FreeRTOS to STM32F105, is ported and the migration verification and performance test are carried out. On this basis, divide each function task and design each module program, complete the software design. According to the characteristics of the information interaction between the upper and lower computer, a reliable and effective data communication protocol Modbus, is developed and the interface test program of the upper computer is written with VC. The RS485 communication between PC and the controller is realized. 4. The hardware and software of the controller are debugged jointly, and all kinds of actual faults are simulated, and the protection characteristics of the controller are tested. The test results show that the hardware and software design of the controller is reasonable, and it can effectively protect all kinds of faults of low voltage motor, and the performance can meet the needs of practical application.
