【摘要】：煤矿工作中,产出以及效率是十分重要的。随着工业自动化已经使用在了矿井作业中,与以前相比,现在煤炭的采集工作中,已经遍布了电子仪器。这种现代化的服务为采矿工业提供了很大的便利。随着大量非线性负荷接入煤矿电网,降低了煤矿电网的电能质量,并且现在煤矿对接入的非线性负荷进行检测的时候会以极高的标准来衡量电能质量。因此现在人们对于煤矿用电的电能质量提出了很高的要求。本论文中出现的对非线性电荷进行检测的系统架构是以数字信号处理器及复杂可编程逻辑器件所构成。此系统是用数字信号处理器为基础。此系统不仅可以检测非线性负荷还可以对其他多种电能的相关参数进行检测。例如对电压、电流等都可以做出切实有效的检测。这个检测装置同时还加成了很多其他功能,例如对特定时间点的成规律有效性记录。而同时,其还可以支持SD卡接口的扩充,这对系统对数据的存取也有很大帮助。系统的通信方式可以分为RS485本地通信和以太网远程通信。在这两种通信方式中中,RS485可以帮助用户对统计数据进行数字化管理,而网络接口可以使数据直接进行传输。本文主要介绍了以下部分：首先介绍了国内外电能质量检测的技术与现实,再对电能质量相关参数的测量方法做了简述。之后对该系统的硬件设计以及软件设计都做了基本介绍。最后再通过对系统的检测来证明装置的切实有效。论文最后对于系统进行了性能的测试,并说明了一些装置运行中的机制。在最后的系统测试中可以得出,这个装置的检测功能强大,有着较高的精密度。并且该装置具有很多附加作用,可以帮助用户得到更好的使用体验。因此该装置在市场中具有极强的竞争力。
[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.
