系統(tǒng)功能system functions

  ■數(shù)據(jù)處理 Data Processing

   智能管理單元利用對比法、近似值法、經(jīng)驗值法、逐次逼近法等方法和手段對采集的數(shù)據(jù)進行處理，并且根據(jù)晶體硅特征曲線方程進行分析、判斷，獲得深層數(shù)據(jù)信息，進行分類上傳、儲存管理。

Intelligent management unit uses contrast methods, approximation methods, empirical value methods, and successive approximation methods for data collection/processing. It also uses the crystal silicon characteristic curve to perform analysis and obtain deeper data, then classifies information and upload for later management.

  ■常規(guī)檢測 Regulatory Tests

   通過采集灰度傳感器輸出數(shù)據(jù)、位置開關(guān)狀態(tài)數(shù)據(jù)、心跳開關(guān)狀態(tài)數(shù)據(jù)等進行工作狀況檢測，獲得組件清潔度及執(zhí)行單元狀態(tài)，以便決定是否啟動清掃或告警。

Working condition is detected by collecting the output gray sensor data and position switch state data, heartbeat switch state data, then obtaining the assembly cleanliness and execution unit status, in order to decide whether to start cleaning or alert.

  ■異常檢測 Anomaly Detection

   管理單元通過比較、近似運算等以及熱斑掃描，對組件陳列進行異常檢測，并將檢測結(jié)果及時上傳至調(diào)度中心。

The management unit performs abnormal detection of component display by comparing, approximate calculation and hot spot scanning, and uploads the test result to the dispatching centre in time.

  ■智能清掃 Automated Cleaning

   管理單元通過得到的清潔度數(shù)據(jù)，與設(shè)定的閾值進行比較，一旦超過閾值，就啟動清掃作業(yè)。在清掃的同時不斷進行清潔度檢測處理，當(dāng)清潔度達到合格閾值時（或者達到設(shè)定清掃次數(shù)，而完全為自動、智能處理。）

The management unit compares real-time data with the set threshold, and once the threshold is exceeded, the cleaning process initiates. The cleaning test is carried out at the same time of cleaning, and when the cleanliness reaches the acceptable threshold value (or when the cleaning times are set up, it is completely automatic and intelligent processing)

  ■熱斑檢測 Heat Wave Sensors

   管理單元每次清掃過程中，隨著執(zhí)行單元的運動，裝設(shè)于執(zhí)行單元之上的紅外溫度傳感器會對每一塊組件的電池片進行熱斑掃描檢測，一旦發(fā)現(xiàn)有溫度異常的電池片，則記錄下該電池片的坐標(biāo)，并發(fā)出告警信息。

With the unit movement in the cleaning process, infrared temperature sensors installed on the execution unit will test for heat of each cell. Once anomalies are found in cell temperature,  the unite records coordinates of the cell, and sends alert information.

  ■安全驅(qū)鳥 Bird Security

   對分布式水面或或農(nóng)業(yè)大棚等鳥類活動頻繁區(qū)域的光伏電站，可以使用帶安全驅(qū)鳥器功能的管理單元。在不需要清掃的時間里，驅(qū)鳥器會以及低的耗電量，采用快速的運動及聲音方式達到驅(qū)鳥效果，避免鳥類停留在組件上造成鳥糞，鳥爪污染電池板。

For the photovoltaic power plants with distributed water surface or agricultural and bird parks, the management units with safety bird drives can be used. In times where cleaning is not required, the bird prevention system will use the lowest power consumption to activate quick movement sound to prevent birds staying on the component to avert bird droppings, and bird claw polluting battery panels.

  ■信息傳輸 Data Transmission

   管理單元設(shè)計有現(xiàn)場總線（RS485）或無線通信接口，與遠程調(diào)度室通信，將采集的原始數(shù)據(jù)及深層數(shù)據(jù)上傳至調(diào)度中心；并且接收調(diào)度中心下發(fā)的指令。為光伏電站智能化的運維管理要求提供最底層、最基礎(chǔ)的數(shù)據(jù)保障和信息傳輸手段。

The management unit design (RS485) has a wireless communication interface to communicate with the remote control room, upload original data & underlying data to the dispatch centre and to receive instructions issued by the dispatch centre. It provides the most basic data security and information transmission means for the photovoltaic power station intelligent operation and maintenance management.
