【正文】 目 錄 引言 A high degree of automation, is easy to realize the unattended。 Finally, timely to reset treatment, lest vehicle near the sensor for roundtrip motion error count. Advantages: the system USES judgement, counting action repeatedly logic accurate and reliable。t count。 優(yōu)點(diǎn)：本系統(tǒng)采用反復(fù)邏輯判定，計(jì)數(shù)動(dòng)作準(zhǔn)確可靠；設(shè)備簡(jiǎn)單安裝方便；自動(dòng)化程度高，便于實(shí)現(xiàn)無(wú)人值守；抗干擾能力強(qiáng)，環(huán)保無(wú)污染；便于需要時(shí)進(jìn)行擴(kuò)展。為了防止意外計(jì)數(shù)錯(cuò)誤，本系統(tǒng)采用反復(fù)程序校驗(yàn)，來(lái)提高系統(tǒng)的可靠性。論文寫作指導(dǎo)： 625880526 論文資源網(wǎng) 最專業(yè)的畢業(yè)論文、設(shè)計(jì)資源分享、下載平臺(tái) 摘 要 本設(shè)計(jì)是基于 PLC 的車輛出入庫(kù)管理系統(tǒng)， 采用光傳感器采集信號(hào)，完全使用 PLC控制， 進(jìn)行 車輛出入庫(kù) 時(shí) 的統(tǒng)計(jì)和顯示工作 ， 采用兩位 LED 來(lái)顯示車庫(kù)內(nèi)車輛的實(shí)際數(shù)量。使用兩個(gè)光傳感器來(lái)監(jiān)控車輛的進(jìn)出并完成計(jì)數(shù)工作，車輛進(jìn)入時(shí)經(jīng)過(guò)兩個(gè)傳感器使顯示數(shù)字加一，車輛外出時(shí)經(jīng)過(guò)兩個(gè)傳感器使顯示數(shù)字減一，但當(dāng)車輛只經(jīng)過(guò)一個(gè)傳感器時(shí)不計(jì)數(shù)。首先，注意控制兩個(gè)傳感器之間的距離，用程序驗(yàn)證進(jìn)出車庫(kù)的是否是車輛，當(dāng)人通過(guò)傳感器時(shí)不計(jì)數(shù)；其次，采用邏輯互鎖方 式，啟動(dòng)加計(jì)數(shù)則要鎖定減計(jì)數(shù)，產(chǎn)生加計(jì)數(shù)脈沖時(shí)則要鎖定減計(jì)數(shù)脈沖，如此以保證可靠性；最后，及時(shí)的進(jìn)行復(fù)位處理，以免車輛在傳感器附近作往返運(yùn)動(dòng)時(shí)錯(cuò)誤計(jì)數(shù)。 缺點(diǎn)： PLC 的輸入口資源優(yōu)點(diǎn)過(guò)于浪費(fèi) 關(guān)鍵詞： PLC 車輛 傳感器 計(jì)數(shù) 可靠性 論文寫作指導(dǎo)： 625880526 論文資源網(wǎng) 最專業(yè)的畢業(yè)論文、設(shè)計(jì)資源分享、下載平臺(tái) ABSTRACT This design is based on PLC vehicles inout warehouse management system, adopting light sensors to collect signals, fully use PLC control, the statistics and unloading vehicles, using two display work LED to show the actual number of garages vehicles. Use two optical sensors to monitor and plete count passing in and out of traffic, car entering after two sensors to display when digital plus one, vehicles go out after two sensors to display digital subtraction one, but when the vehicle just after a sensor not counting. In order to prevent accidental counting error, this system USES repeated program check, to improve the system reliability. First, attention to control the distance between the two sensors, and the garage with program verifying whether vehicles, when people don39。 through the sensor Secondly, adopting logic interlock way, start to add
