摘要

本研究利用無線網路和數位電表建立一套無線電源監控系統。此系統包括無線數位電表、轉傳器、閘道器以及監控伺服器。當監測環境複雜造成通訊干擾時，本研究採用跳頻來進行改善。除此之外，伺服器的監控人機介面程式可以進行即時與長期數據分析。
本系統在待測設備上裝置無線數位電表，透過無線傳輸方式將所量測的電力資料傳至轉傳器，再轉傳至閘道器；傳至監測系統伺服器後，存入資料庫，得以將數據進行保存、整理並且可以在客戶端以圖表方式顯示歷史資料以利後續分析工作。為了減少轉傳器數目以降低成本，本論文利用Floyd最短路徑演算法來取得資料傳輸的最佳路徑。在頻道壅塞時，再利用跳頻的實驗數據找出傳送率較高的頻道，設定傳輸頻道。
最後，本研究將所設計的監控系統在實際環境中進行佈建並透過長期的監控證實本系統的可靠性。由監控資料與分析結果證實，本論文所建立的系統，具有長期監控電源的能力，且能利用擷取的電力參數資料進行後續的節能分析。

In this thesis, a wireless power monitoring system is proposed by using wireless digital power meters, repeaters, gateways and monitoring server. When the monitoring environment influences the communication, the frequency hopping technique is used to reduce the interference. Moreover, the real time and long-term analysis can be done via the monitoring graphical user interface built on the server
Wireless power meters mounted on the power sources measure the power signals and transmit the acquired data to the repeaters and then to the gateway. When the server of the monitoring system receives the data passed by the gateway, these measured data are processed and stored into a database in the form of designed schema. As a result, clients can use the graphical analysis tool to display the historical data and investigate detailed information. Also, to reduce the setup cost, the Floyd algorithm is used to find the data transmission route with the smallest number of repeaters. When communication channel is jammed, a frequency hopping solution is adopted to improve the successful transmission rate.
Finally, the monitoring system proposed by this work is implemented in the field and performs long-term monitoring to examine the reliability. From the monitored data and analyzed results, it indicates that the proposed system has the ability to on-line and long-term monitors the power sources. It is also found that the acquired power signal parameters can be used to carry out the power-saving analysis
