PLC的發(fā)展歷程有了一定的認識和了解,并對它的工作原理進行了深入的學習和探討,在我們都意識到它重要性的今天,我們選擇了題為《六人控制投票機系統(tǒng)》的課題進行分析和設計,根據(jù)控制要求,明確設計任務,擬定設計方案與進度計劃,運用所學的理論知識,以鞏固我們的理論學習,以提高我們的操作能力,以加強我們的專業(yè)技能,讓我們更好地將理論聯(lián)系實踐并將理論應用于實踐 ,全面提升我們發(fā)現(xiàn)問題、分析問題、解決問題的能力mputer)也簡稱PC。為了避免混淆,人們將最初用于邏輯控制的可編程控制器。關鍵詞:可編程控制器PLC;六人控制投票機; 梯形圖Abstract Programmable controller referred to the PC. Personal puters are also referred to as the avoid confusion, the people will be initially used for logic control of the programmable controller called the PLC. PLC is a specialized numbercrunching applications in industrial environments designed to operate electronic devices. It can be programmed memory, used to perform logical operations in its internal storage, sequential operation, timing, counting and arithmetic operations, such as operating instructions, and can be digital and analog inputs and outputs to control various types of machinery or production processes. PLC and its peripherals should be designed in accordance with the principle of easy to form a whole, and industrial control system, easy to extend its functionality. Programmable controller is a new type of mon control equipment, it will traditional relays, contact device control technology, puter technology and munication technology organic unifies in together, specifically for industrial control and design, this new type of general automatic control device with its high reliability, strong adaptability and working envi
