如圖2所示，係本發明工業現場遠端監控方法較佳實施例的作業流程圖。 2 is a flow chart of the operation of the preferred embodiment of the industrial site remote monitoring method of the present invention.
步驟S10，監控電腦3中的資料獲取與監視控制器30從PLC 2中採 集現場設備1的監控資料。所述監控資料包括現場設備1的運轉狀況和檢測參數。所述現場設備1的運轉狀況包括啟動狀態、關閉狀態及故障狀態。所述檢測參數根據現場設備1進行確定，不同的現場設備1有不同的檢測參數，例如：廢水自動化處理設備的檢測參數包括，但不限於，現場的PH值、化學需氧量、暫態流量及累計流量。 In step S10, the data acquisition and monitoring controller 30 in the monitoring computer 3 is taken from the PLC 2. Set monitoring data of field device 1. The monitoring data includes the operating conditions and detection parameters of the field device 1. The operating conditions of the field device 1 include an activated state, a closed state, and a fault state. The detection parameters are determined according to the field device 1. Different field devices 1 have different detection parameters. For example, the detection parameters of the automatic wastewater treatment equipment include, but are not limited to, the PH value, the chemical oxygen demand, and the transient flow rate at the site. And cumulative traffic.
步驟S12，監控電腦3將所採集的監控資料儲存至本地資料庫32和資料庫伺服器4的即時資料表40。監控電腦3將所採集的監控資料儲存至本地資料庫32，以防止在監控電腦3與資料庫伺服器4間即時通信出現故障時丟失資料，並在監控電腦3與資料庫伺服器4正常通信時，將儲存在本地資料庫32中的監控資料傳送給資料庫伺服器4。所述監控電腦3每間隔一定的時間對所採集的監控資料進行儲存，所述間隔的時間可根據需要自行設置，例如：每隔5秒將所採集的監控資料進行儲存。所述即時資料表40用於儲存當前從資料獲取與監視控制器30傳送來的監控資料。當有新的監控資料儲存至即時資料表40時，所述新的監控資料將覆蓋上一次所儲存的監控資料。 In step S12, the monitoring computer 3 stores the collected monitoring data to the local data database 32 and the real-time data table 40 of the database server 4. The monitoring computer 3 stores the collected monitoring data to the local database 32 to prevent data loss when the instant communication between the monitoring computer 3 and the database server 4 fails, and the monitoring computer 3 and the database server 4 communicate normally. The monitoring data stored in the local database 32 is transferred to the database server 4. The monitoring computer 3 stores the collected monitoring data every time interval, and the interval time can be set according to requirements, for example, the collected monitoring data is stored every 5 seconds. The real-time data table 40 is used to store the monitoring data currently transmitted from the data acquisition and monitoring controller 30. When new monitoring data is stored in the real-time data table 40, the new monitoring data will overwrite the last stored monitoring data.
步驟S14，資料庫伺服器4判斷所採集的監控資料是否成功儲存至即時資料表40中。當所採集的監控資料全部儲存至即時資料表40中時，判斷所採集的監控資料成功儲存至即時資料表40中；當所採集的監控資料沒有或部分儲存至即時資料表40中時，判斷所採集的監控資料沒有成功儲存至即時資料表40中。 In step S14, the database server 4 determines whether the collected monitoring data is successfully stored in the real-time data table 40. When all the collected monitoring data are stored in the real-time data table 40, it is judged that the collected monitoring data is successfully stored in the real-time data table 40; when the collected monitoring data is not or partially stored in the real-time data table 40, it is judged The collected monitoring data was not successfully stored in the real-time data table 40.
步驟S16，當所採集的監控資料沒有成功儲存至即時資料表40中時，監控電腦3將本地資料庫32中的監控資料儲存至即時資料表 40。當所述本地資料庫32中監控資料成功儲存至資料庫伺服器4的即時資料表時，所述監控電腦3自動清空本地資料庫32中的資料。 In step S16, when the collected monitoring data is not successfully stored in the real-time data table 40, the monitoring computer 3 stores the monitoring data in the local database 32 to the real-time data table. 40. When the monitoring data in the local database 32 is successfully stored in the real-time data table of the database server 4, the monitoring computer 3 automatically clears the data in the local database 32.
步驟S18，當所述監控資料成功儲存至即時資料表40中，資料庫伺服器4將所述監控資料從即時資料表40儲存至歷史資料表42。所述歷史資料表42用於儲存所有從即時資料表40傳送來的監控資料，以供用戶查看歷史記錄。所述資料庫伺服器4每隔一定的時間將即時資料表40中的監控資料儲存至歷史資料表42中，所述間隔的時間可根據需要自行設置，例如：每隔10分鐘將即時資料表40中的監控資料儲存至歷史資料表42中。 In step S18, when the monitoring data is successfully stored in the real-time data table 40, the database server 4 stores the monitoring data from the real-time data table 40 to the historical data table 42. The historical data table 42 is used to store all the monitoring data transmitted from the instant data table 40 for the user to view the history. The database server 4 stores the monitoring data in the real-time data table 40 into the historical data table 42 at a certain time. The interval time can be set according to requirements, for example, the real-time data table is displayed every 10 minutes. The monitoring data in 40 is stored in the historical data table 42.
步驟S20，資料庫伺服器4將即時資料表40中的監控資料傳送到Web伺服器5。所述Web伺服器5中儲存有現場設備1的監控畫面，Web伺服器5接收到監控資料後，將所述監控資料顯示在該監控畫面上。所述監控畫面上所顯示的資料根據即時資料表40中所更新的資料不斷變化，監控終端6可透過Web伺服器5流覽到所述監控畫面，對現場設備1的運轉狀況和檢測參數進行監控。 In step S20, the database server 4 transmits the monitoring data in the real-time data table 40 to the web server 5. The web server 5 stores a monitoring screen of the field device 1. After receiving the monitoring data, the web server 5 displays the monitoring data on the monitoring screen. The data displayed on the monitoring screen is continuously changed according to the data updated in the real-time data table 40, and the monitoring terminal 6 can browse the monitoring screen through the web server 5 to perform the operation status and the detection parameters of the field device 1. monitor.
步驟S22，Web伺服器5監控所述監控畫面中的監控資料是否出現異常。當現場設備處於啟動狀態或關閉狀態，及檢測參數處於預先設定的檢測參數正常範圍之內時，判斷所述監控畫面中的現場設備及檢測參數未出現異常；當現場設備處於故障狀態，及/或檢測參數不在預先設定的檢測參數正常範圍之內時，判斷所述監控畫面中的現場設備及檢測參數出現異常。 In step S22, the web server 5 monitors whether the monitoring data in the monitoring screen is abnormal. When the field device is in the startup state or the shutdown state, and the detection parameter is within the normal range of the preset detection parameter, it is determined that the field device and the detection parameter in the monitoring screen are not abnormal; when the field device is in a fault state, and / When the detection parameter is not within the normal range of the preset detection parameter, it is determined that the field device and the detection parameter in the monitoring screen are abnormal.
步驟S24，當所述監控畫面中的監控資料出現異常時，Web伺服器5在監控畫面中將異常標示出來，並將異常資訊發送給對應的監 控終端6。例如：當所述工業設備1或檢測參數出現異常時，將監控畫面中代表工業設備1的位置或檢測參數的資料標示為紅色，以警示相關工作人員儘快進行相對應的處理。所述監控畫面還可整合視頻監控，當所述監控畫面中出現異常時，點擊出現異常的位置，則可進入視頻監控畫面，即時顯示現場設備1的運作畫面。 Step S24, when the monitoring data in the monitoring screen is abnormal, the web server 5 marks the abnormality in the monitoring screen, and sends the abnormal information to the corresponding supervisor. Control terminal 6. For example, when the industrial equipment 1 or the detection parameter is abnormal, the information representing the position or the detection parameter of the industrial equipment 1 in the monitoring screen is marked as red to warn the relevant staff to perform the corresponding processing as soon as possible. The monitoring screen can also integrate video monitoring. When an abnormality occurs in the monitoring screen, clicking the abnormal position can enter the video monitoring screen to instantly display the operation screen of the field device 1.
