【摘要】：煤礦工作中,產出以及效率是十分重要的。隨著工業(yè)自動化已經使用在了礦井作業(yè)中,與以前相比,現(xiàn)在煤炭的采集工作中,已經遍布了電子儀器。這種現(xiàn)代化的服務為采礦工業(yè)提供了很大的便利。隨著大量非線性負荷接入煤礦電網,降低了煤礦電網的電能質量,并且現(xiàn)在煤礦對接入的非線性負荷進行檢測的時候會以極高的標準來衡量電能質量。因此現(xiàn)在人們對于煤礦用電的電能質量提出了很高的要求。 本論文中出現(xiàn)的對非線性電荷進行檢測的系統(tǒng)架構是以數字信號處理器及復雜可編程邏輯器件所構成。此系統(tǒng)是用數字信號處理器為基礎。此系統(tǒng)不僅可以檢測非線性負荷還可以對其他多種電能的相關參數進行檢測。例如對電壓、電流等都可以做出切實有效的檢測。這個檢測裝置同時還加成了很多其他功能,例如對特定時間點的成規(guī)律有效性記錄。而同時,其還可以支持SD卡接口的擴充,這對系統(tǒng)對數據的存取也有很大幫助。系統(tǒng)的通信方式可以分為RS485本地通信和以太網遠程通信。在這兩種通信方式中中,RS485可以幫助用戶對統(tǒng)計數據進行數字化管理,而網絡接口可以使數據直接進行傳輸。 本文主要介紹了以下部分：首先介紹了國內外電能質量檢測的技術與現(xiàn)實,再對電能質量相關參數的測量方法做了簡述。之后對該系統(tǒng)的硬件設計以及軟件設計都做了基本介紹。最后再通過對系統(tǒng)的檢測來證明裝置的切實有效。論文最后對于系統(tǒng)進行了性能的測試,并說明了一些裝置運行中的機制。 在最后的系統(tǒng)測試中可以得出,這個裝置的檢測功能強大,有著較高的精密度。并且該裝置具有很多附加作用,可以幫助用戶得到更好的使用體驗。因此該裝置在市場中具有極強的競爭力。
[Abstract]:In coal mine work, output and efficiency are very important. As industrial automation has been used in mine operations, the collection of coal is now covered with electronic instruments. This modern service has greatly facilitated the mining industry. With a large number of nonlinear loads connected to the coal power network, the power quality of the coal power network has been reduced, and the power quality will be measured by a very high standard when the coal mine detects the connected nonlinear load. Therefore, people now put forward a very high demand for the power quality of coal mine electricity. In this paper, the system architecture of nonlinear charge detection is composed of digital signal processor and complex programmable logic device. The system is based on a digital signal processor. This system not only can detect nonlinear load, but also can detect related parameters of other kinds of electric energy. For example, voltage and current can be effectively detected. The device also adds a number of other features, such as a regular validity record at a particular point in time. At the same time, it can support the expansion of SD card interface, which is also very helpful for the system to access data. The communication mode of the system can be divided into RS485 local communication and Ethernet remote communication. In these two communication modes, RS485 can help users digitally manage the statistical data, while the network interface can make the data transmit directly. This paper mainly introduces the following parts: firstly, it introduces the technology and reality of power quality measurement at home and abroad, and then gives a brief introduction to the measuring methods of power quality related parameters. After that, the hardware design and software design of the system are introduced. Finally, through the detection of the system to prove the effectiveness of the device. Finally, the performance of the system is tested, and some mechanisms in operation are explained. In the final system test, it can be concluded that the detection function of this device is powerful and has high precision. And the device has many additional functions, can help users to get a better use of experience. Therefore, the device is highly competitive in the market.
