如今,各大鋼鐵公司原料場翻車機與地上的通訊傳輸方法分為有線傳輸和無線傳輸兩種。有線傳輸通常選用多芯通訊電纜為載體,以挂纜滑車或拖鏈的形式裝置。挂纜滑車方法裝置的電纜在設備移動的進程中頻頻拉伸和曲折,易折斷,而且替換電纜的作業量也是非常大。電纜拖鏈是近年逐步呈現的一種方法,雖然有用操控了電纜的拉伸和曲折,但是其高昂的出資本錢,也讓普通用戶望而生畏。別的,電纜長時間暴露室外,腐蝕磨損嚴重,絕緣也遭到破壞。那麼,能否以較低本錢的處理移動設備通訊疑問已是燃眉之急。
本文要點討論怎麼利用西門子工業無線網絡產品實如今漣源鋼廠翻車機體係中的運用。無線網絡技術的運用能大大進步工程機械作業時的係數,降低出資本錢,為施工供給便當條件,使得雜亂的操控體係簡略化。
1 翻車機體係運轉工況
漣源鋼廠該項目有我廠翻車機體係3套,每套體係為貫通式安置,構成有翻車機和重車調車機等。該體係的作業進程如下:
重車調車機牽引一節滿載敞車定坐落翻車機的托車梁上。靠板振動器在液壓缸的推進下靠向敞車一側。壓車臂下落壓住敞車兩邊車幫。當靠板靠上、壓車臂壓住、重車調車機臂已駛出翻車機後,翻車機開端以正常速度翻卸,直到挨近160度左右減速、泊車。然後,翻車機以正常速度回翻,抵達零位時,靠板撤退,壓車臂開端抬起,當壓車臂上到高位、靠板退到終位、重車調車機牽引第二節滿載敞車, 進入翻車機趁便頂出已翻卸的空車。翻車機就完成了一個作業循環。
全部體係,翻車機和重車調車機為移動設備,設備上有許多傳感器,而且重調機的就地操作箱隨車體移動,翻車機就地操作箱在地上上不移動。現場還有一些別的的操控信號,如:夾輪器操作箱、液壓信號、挨近開關等。
2 翻車機plc無線分站操控體係構成
依據現場設備安置,全部體係規劃選用總線和無線混合的PLC操控計劃,請求到達運轉牢靠、本錢優、布線簡略、施工便當。改計劃規劃由1個PLC主站(坐落會集操作臺內),3個PLC ControlNet分站,2個PLC無線分站和5個變頻器ControlNet分站構成。其間, 2個移動分站無線以太網802.11協議與主站進行通訊。漣鋼原料場翻車機PLC選用AB公司的Logix5000係列產品,變頻器選用AB公司的POWERFLEX 700S係列產品。
主站PLC以太網模塊銜接至西門子SCALANCE W788-1PRO設備,而且運用西門子PST軟件設置該設備為接入點,IP地址為:192.168.1.63。從站PLC以太網模塊銜接至西門子SCALANCE W744-1PRO客戶端,運用PST軟件設置其IP地址別離設置為:192.168.1.64(無線客戶端1:重調機車體操作箱PLC分站),192.168.1.65(無線客戶端2:翻車機車體接線箱PLC分站)。天線為ANT792-6MN全向天線,選用10米長的RCoax N/R-SMA 天線饋線銜接接入點或客戶端。因為體係運轉時,重調機和翻車時機迅速大規模的移動。為確保無線通訊的高質量,天線的裝置,請求在設備運轉的進程中主站天線和從站天線能直接可視。
在進行PST設置時,三套翻車機體係的SSID請求別離獨立,且各體係內僅有,別離設置為FCJ1、FCJ2、FCJ3。每個體係無線模式挑選2.4GHZ 54Mbps(802.11g),信道設置為主動挑選。頻率可調規模2.4 ~ 2.4835 GHz,而且特有的IPCF功用確保體係通訊的確定性。
3 AB Logix5000 PLC軟件對無線分站的組態
在RSLogoix5000編程軟件的硬件組態界面中,進行全部體係的硬件裝備組態。,主站以太網通訊模塊1756-ENBT下別離創立2個分站以太網通訊模塊1756-ENBT銜接,主站和2個從站的IP地址別離設定為:192.168.1.63、192.168.1.64、192.168.1.65。然後,對2個無線分站的模塊進行裝備。接著,對PLC程序進行下載,下載完成後,運用AB的RSLink軟件的RSWho功用,聯係前面臨無線客戶端的設置,能夠查找到無線網絡中2個分站的硬件裝備。
4 SCALANCE W744-1PRO客戶端的通訊質量
運用西門子PST軟件記載運轉時,2個分站信號傳遞的質量,採樣周期設置為100ms。信號質量抱負狀況高為100。實踐運轉進程中,無線客戶端1的信號質量較無線客戶端2的信號質量弱,無線客戶端1的信號質量剎那間低時為55,無線客戶端2的信號質量剎那間低時為75,原因是因為重車調車機(無線客戶端1)在移動至遠端時,被翻車機(無線客戶端2)遮擋住了一部分,且無線客戶端1移動間隔較遠。別的,這2個無線客戶端都存在周期性剎那間信號質量降低的景象,但這並沒有影響設備的接連牢靠運轉。
5 結語
試運轉半年後,考慮到三臺翻車機相鄰安置,三臺翻車機無線信號也許存在彼此幹擾的景象,咱們對三臺翻車機的無線通訊進行了優化。把相鄰的SCALANCE W788信道設置成不一樣的通道,這使得設備運轉時,通訊質量有相當可觀的進步,曾經存在的信號質量剎那間周期性降低的景象根本不見,通訊信號質量簡直穩定在100。
漣鋼翻車機運用無線分站進步了體係的牢靠性和裝置施工功率,減小了體係維護量,降低了出資本錢。三臺PLC無線通訊規劃的翻車機運轉至今已有4年,牢靠,主動,為漣鋼生產作出了重要貢獻。
