【摘要】:隨著智能水表技術(shù)的發(fā)展,實(shí)時監(jiān)控系統(tǒng)使供水部門可以擁有大量關(guān)于供水管網(wǎng)屬性的數(shù)據(jù)。智能水表包括記錄水量和通信系統(tǒng)兩部分,可以實(shí)時傳輸和儲存用水量數(shù)據(jù)。智能水表已經(jīng)被廣泛應(yīng)用,大多數(shù)城市都具有這樣的設(shè)備,然而智能水表傳送的關(guān)于管網(wǎng)屬性的數(shù)據(jù),水司僅僅用于日常調(diào)度和經(jīng)濟(jì)效益考評,之后這些大量數(shù)據(jù)會被儲存一段時間。智能水表連續(xù)傳送數(shù)據(jù),隨著數(shù)量逐漸增大,水司會因?yàn)閮?nèi)存原因而把這些數(shù)據(jù)刪除,同時刪除的還有這些數(shù)據(jù)所含有的非常有價值的管網(wǎng)信息。隨著數(shù)據(jù)挖掘技術(shù)的發(fā)展,我們有技術(shù)有能力處理分析這些數(shù)據(jù),最大程度地挖掘數(shù)據(jù)所包含信息。分析這些數(shù)據(jù)有助于供水管網(wǎng)革新供水管網(wǎng)管理、計(jì)劃和用戶服務(wù),更加充分利用水資源,保護(hù)水資源。本文根據(jù)DMA分區(qū)流量數(shù)據(jù)特點(diǎn),提出一種聚類方法,即基于DMA分區(qū)用水量曲線距離和形狀的聚類算法(KS),該聚類方法相對經(jīng)典K-means、自主映射(SOM)和模糊C均值而言,更能體現(xiàn)DMA分區(qū)用水量規(guī)律。通過Y市DMA分區(qū)項(xiàng)目中獲得43個DMA分區(qū)的流量數(shù)據(jù),對這43個DMA分區(qū)流量數(shù)據(jù)進(jìn)行數(shù)據(jù)預(yù)處理之后,進(jìn)行聚類分析,比較KS、K-means、SOM和FCM四種聚類算法效果,最終表明KS的聚類效果最好,并且通過分析KS聚類結(jié)果,能夠指導(dǎo)水司檢測異常情況(漏損、偷水)。在對43個DMA分區(qū)流量數(shù)據(jù)處理過程中,通過觀察43個DMA分區(qū)的用水量變化曲線,發(fā)現(xiàn)根據(jù)《給水工程》等教材計(jì)算出的時變化系數(shù),小于大多數(shù)各小時用水量占全天總用水量比例。說明若繼續(xù)采用《給水工程》等教材中的時變化系數(shù)公式,將不能保證如Y市這樣城市的供水安全,建議進(jìn)一步修正時變化系數(shù)公式。
[Abstract]:With the development of intelligent water meter technology, the real-time monitoring system enables the water supply department to have a lot of data about the properties of the water supply network. The intelligent water meter includes two parts: recording water quantity and communication system, which can transmit and store water consumption data in real time. Smart water meters have been widely used, and most cities have such devices. However, the intelligent water meters transmit data about the properties of the pipe network, which are only used by the Water Department for routine operation and economic efficiency evaluation. After that, the bulk of the data will be stored for some time. Intelligent water meters continuously transmit data, and as the number increases, the Water Division removes the data for memory reasons, as well as the valuable pipe network information contained in the data. With the development of data mining technology, we have the ability to process and analyze the data, and to mine the information contained in the data to the maximum extent. The analysis of these data is helpful to the innovation of water supply network management, planning and user service, making better use of water resources and protecting water resources. In this paper, according to the characteristics of DMA traffic data, a clustering algorithm based on the distance and shape of DMA partition water consumption curve is proposed. The clustering method (KS), is relative to classical K-means, autonomous mapping (SOM) and fuzzy C-means. More can reflect the DMA zoning water consumption law. The traffic data of 43 DMA districts were obtained from the DMA sub-area project of Y city. After data preprocessing of 43 DMA partition traffic data, clustering analysis was carried out, and the results of four clustering algorithms, KS,K-means,SOM and FCM, were compared. The result shows that the clustering effect of KS is the best, and by analyzing the clustering results of KS, it can guide the Water Division to detect abnormal conditions (leakage, stealing). In the process of flow data processing in 43 DMA subzones, by observing the variation curves of water consumption in 43 DMA zones, the time-varying coefficients calculated from the teaching materials, such as Water supply Engineering, etc., are found out. Less than most hours of water consumption in the total water consumption of the whole day. It is shown that if the formula of time-varying coefficient in the teaching materials such as Water supply Engineering continues to be used, the safety of water supply in cities such as Y City will not be guaranteed, and it is suggested that the formula of time-varying coefficient should be further revised.
