【摘要】：電動機作為拖動系統(tǒng)中的重要組成部分,在國民經(jīng)濟中占有舉足輕重的地位。它的使用幾乎滲透到了各行各業(yè),是工業(yè)、農(nóng)業(yè)和國防建設(shè)及人民生活正常進行的重要保證,因而確保電動機的正常運行就顯得十分重要。而在實際使用過程中,由于普通的電機綜合保護控制器的局限性,很多情況下電機不能得到有效保護,時常容易造成電機燒毀甚至引發(fā)重大安全事故。全國每年因電動機燒毀消耗大量的電量、維修損耗,而因停工停產(chǎn)所造成的損失更是一個無法估量的巨大數(shù)目。因此做好電動機的保護具有節(jié)能顯著、提高生產(chǎn)效率和經(jīng)濟效益及保證安全生產(chǎn)的重要意義。本文主要工作內(nèi)容如下:1.根據(jù)低壓電機控制器的發(fā)展現(xiàn)狀和基本原理,分析確定了基于STM32F105的硬件架構(gòu),并設(shè)計了控制器各模塊的硬件電路。2.移植嵌入式實時操作系統(tǒng)FreeRTOS至STM32F105,并進行移植驗證和性能測試。在此基礎(chǔ)上,劃分各個功能任務(wù)并設(shè)計各模塊程序,完成軟件設(shè)計。3.根據(jù)上下位機信息交互的特點,制定可靠有效的數(shù)據(jù)通信協(xié)議Modbus,并使用VC++編寫上位機界面測試程序,實現(xiàn)了PC和控制器的RS485通信。4.對控制器進行軟硬件聯(lián)合調(diào)試,并模擬各種實際故障,對控制器的保護特性進行測試。測試結(jié)果表明,本控制器軟硬件設(shè)計合理,能很好的對低壓電機的各種故障進行有效保護,性能滿足實際應(yīng)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.
