產(chǎn)品詳情
高壓變頻器首要由控制柜、功率單元柜、變壓器柜和旁路柜4有些構(gòu)成?？刂乒褡鳛橄?shù)高壓變頻器的基地有些，對悉數(shù)系統(tǒng)進(jìn)行操作及控制。包括對功率單元PWM調(diào)制，控制 IGBT通斷來輸出單相脈沖調(diào)制波形、經(jīng)過主站宣告的指令來對悉數(shù)系統(tǒng)進(jìn)行操作、缺點(diǎn)時分的對悉數(shù)系統(tǒng)的主要保護(hù)以及有關(guān)數(shù)據(jù)信息的閃現(xiàn)。鑒于高壓變頻器對系統(tǒng)可靠性高，抗干擾性強(qiáng)及拓寬性豐盛等特色，本主控系統(tǒng)選用臺達(dá)出產(chǎn)的DVP系列plc和DOP-B系列觸摸屏來參加控制。
DVP系列可編程邏輯控制器以高速、穩(wěn)健、高可靠度應(yīng)用于許多工業(yè)自動化機(jī)械上；除了具有靈敏實(shí)行邏輯運(yùn)算、豐盛的指令集、多元擴(kuò)展功用卡及高性價比等特征外，而且支持多種通訊規(guī)范。 DVP系列PLC通常具有兩個通訊口（ES2在外），COM1是RS232,COM2是RS485，支持ModBus ASCII/RTU通訊格式，通訊速率最高可達(dá)115200bps，兩通訊口能夠一同運(yùn)用。其供給了關(guān)于ModBus ASCII/RTU方式的專用通訊指令，這么在編寫通訊程序時就能夠大大簡化，無需像用串行數(shù)據(jù)傳送指令RS那樣要進(jìn)行凌亂的校驗(yàn)碼計(jì)算和遵照凌亂的指令格式。
DOP人機(jī)界面供給多樣化尺度與色彩的觸摸屏幕，并為工業(yè)自動化機(jī)械供給靈敏便利的控制功用。此外，全系列產(chǎn)品皆分配Windows-base人性化批改軟件，運(yùn)用者可靈敏批改圖表界面，并可安閑設(shè)定適宜的通訊規(guī)范。
2．系統(tǒng)方案
悉數(shù)主控系統(tǒng)首要由DVP32EH2-L、DVP06XA模擬量拓寬模塊、DVP-F485S通訊卡、DVP16HM11N數(shù)字量拓寬、DOP-B10系列人機(jī)界面以及主控箱一套構(gòu)成。
PLC的COM2作為主站，首要用于系統(tǒng)的邏輯區(qū)分、缺點(diǎn)保護(hù)、DSP從站讀寫操作等。PLC的COM1為從站來和HMI通訊，及時準(zhǔn)確的將系統(tǒng)中的信息顯如今HMI上。在操作方式為本地控制時，由HMI來對悉數(shù)系統(tǒng)進(jìn)行操作。模擬量模塊用來收集變壓器柜中的溫度信號，將溫度控制器傳送來的4~20mA換算成對應(yīng)的溫度值來進(jìn)行閃現(xiàn)，根據(jù)溫控器保護(hù)信號來對系統(tǒng)過溫信號和超高溫信號進(jìn)行保護(hù)。運(yùn)用EH2-L系列PLC的高拓寬性功用，選擇性的拓寬 PFORIFUS通訊模塊、以太網(wǎng)通訊模塊來滿意不一樣客戶的需求。經(jīng)過臺達(dá)PLC支持的規(guī)范Modbus通信協(xié)議，用戶能夠經(jīng)過該端口來對系統(tǒng)進(jìn)行遠(yuǎn)程拜訪。
2.3臺達(dá)PLC在系統(tǒng)中的功用簡述
根據(jù)系統(tǒng)央求，對程序進(jìn)行編制來結(jié)束有關(guān)功用的完結(jié)，具體功用如下：
系統(tǒng)邏輯區(qū)分：系統(tǒng)透過PLC的邏輯區(qū)分來給出系統(tǒng)有關(guān)情況的標(biāo)志位，如系統(tǒng)組織穩(wěn)當(dāng)，高壓合閘容許、高壓已合、央求工作以及系統(tǒng)工作中等等。
缺點(diǎn)保護(hù)：經(jīng)過讀取主控DSP中的缺點(diǎn)信息來將系統(tǒng)中的信息在HMI上作出閃現(xiàn)，遇到重缺點(diǎn)信息靈敏斷開高壓變頻器前端斷路器來堵截設(shè)備電源，對系統(tǒng)進(jìn)行保護(hù)。
系統(tǒng)數(shù)據(jù)讀取：運(yùn)用PLC上的RS485通訊來和DSP進(jìn)行通訊，經(jīng)過查詢的方法來讀取系統(tǒng)工作時分的電流、電壓、頻率等數(shù)值以及對悉數(shù)系統(tǒng)進(jìn)行參數(shù)設(shè)定。
其他功用：該功用中包括工作記載閃現(xiàn)、PID功用調(diào)度、系統(tǒng)溫度閃現(xiàn)等?？蛻粢材軌蚪?jīng)過系統(tǒng)中添加的DVP-F485S通訊拓寬卡來遠(yuǎn)程讀取PLC中開關(guān)量情況及寄存器中的值。
