蓝牙无线通信技术在电能质量监测系统中应用的研究
摘要
工业测控领域对无线通信一直有着较强的需求。在对工业现场电能质量的监测中,有些地方工作环境比较恶劣,进行有线电缆的布线存在诸多不便。此外,线缆易受环境因素的影响而腐蚀、脱落断裂,且面对高强电压,数据读取和监控工作存在易触电等诸多不安全因素。而传统的无线传输技术如红外、射频等技术由于受物体阻碍、电磁干扰以及安全等因素的影响,不能完全满足实际应用的需要。本文提出将蓝牙技术应用于电能质量监测系统,利用CSR公司的BlueCore2蓝牙芯片设计了一套蓝牙无线数据传输系统,以替代原有电能质量监测系统中用于数据传输的有线电缆,较好地解决了上述问题。
蓝牙技术是近年来新发展起的一种近距离无线传输技术。其工作频率为全球统一开放的2.4GHz ISM频段,在功耗、成本及抗干扰性能方面独具优势。并且随着蓝牙技术标准的发展,蓝牙芯片的性能也在不断完善。新一代的蓝牙芯片在数据传输率、传输可靠性和抗干扰性能方面都较之以前有了较大的改进,因此适合应用于各种复杂的工业环境。本文提出的方案即是蓝牙技术在电力系统中的一个应用实例。
采用蓝牙技术的电能质量监测系统不仅替代了原有的有线电缆连接,使得安装维护更为方便,而且利用个人数字助理PDA可以实现对多处监测点的现场实时监测,省却了监测现场大量昂贵的显示设备,同时满足了移动性和可靠性等要求。本文通过HP iPAQ hx2100 Pocket PC并在上面编写相应移动客户端程序实现了上述功能。此外,本文还利用MySQL数据库在Linux操作系统平台上开发了一套电能质量数据库系统,并基于VB开发了电能质量监测系统客户端程序,实现了图形化实时监测等功能,从而满足远程运行管理人员的需求。
为了克服蓝牙传输距离上的不足和将蓝牙更好地应用于工业数据传输,本文还对如何设计蓝牙局域网接入点进行了探讨,并结合理论和仿真分析对蓝牙应用于监测系统的抗干扰性能进行了研究。
There is a strong demand for wireless communication in the industrial measurement and control field. It is not convenient to use cable in some harsh environment where power quality monitoring system works. And cable is often very easy to be eroded by the circumstance. Sometime the device has to work under the high voltage, thus some dangerous factors such as electric shock exist when read data from the device. Conventional wireless technology such as infrared technology and Radio Frequency technology can’t satisfy the real application needs because they are easy to be interrupted by the obstacle and electromagnetic interference. To solve these problems, the thesis proposed a solution of power quality data acquisition system based on BluetoothTM technology and designed a set of Bluetooth wireless data transceiver which used BlueCore2 chip of CSR company.
BluetoothTM is a fast growing, short-range radio technology operating at 2.4GHz in the globally available license-free Industrial, Scientific and Medical(ISM) band. It has good performance of low power, low cost and anti-jamming ability. As the Bluetooth technology standards developing, the Bluetooth chip performance improves. The new generation of Bluetooth chip has better performances in the data transfer rate, transfer reliability and anti-jamming ability, thus it is more suitable to use Bluetooth technology in the industrial field. This thesis is definitely an industrial application example of Bluetooth technology in the power system.
The new power quality monitoring system with Bluetooth technology has more convenience and low cost in the installation and maintenance. And combined with PDA the user can measure and read the real–time power quality data for multiple monitor points at the same time. One of the consequences is that we don’t need lots of expensive display devices any more in the device field. Another is that we get the mobility and reliability. The thesis implemented the function with programming in the PDA of HP iPAQ hx2100 Pocket PC. Besides this, a power quality database system isdeveloped using MySQL database in the Linux OS. Accordingly client software is also developed programming with Visual Basic. It provides many functions like graphic monitor and real-time analysis and meets the needs of remote operating manager.
The thesis researches how to design Bluetooth WLAN-AP(Wireless Local Area Network Access Point) to overcome the shortage of transmission range limit. In addition, in order to apply the Bluetooth technology in industrial field better the anti-jamming ability is researched in detail combined theory and simulation analysis.
