【正文】 option)Can be used as a modification with copy program rapid tool (without programmer), and may carry on auxiliary software filing work. the battery moduleFor long time data backup. User data (such as mark a state, data block, timer, counter) through the internal super capacitance storage about 5 days. Choose the battery module can extend the storage time to 200 days (10 years of my life). The battery module inserted in the memory module card slot.總結(jié)：通過閱讀全自動洗衣機設(shè)計全部過程，發(fā)現(xiàn)自己的專業(yè)英語還是存在著一定的不足，首先是不能夠靈活應用每個單詞的含義，導致在翻譯過程中，容易將單詞的意思曲解，這就給翻譯造成了很大的影響，為了能夠及時的糾正錯誤，我利用了網(wǎng)絡(luò)上的“有道詞典”進行一一的校對，在這里還要感謝張磊老師給予的幫助，使我順利的完成了此次的項目作業(yè)。 control system principleAutomatic washing machine water, laundry, drainage, dehydration is through the water level switch, electromagnetic inlet valve and electromagnetic drain valve with the control, so as to realize automatic control, water level switch is used to control the water washing machine in low high school level, electromagnetic inlet valve plays the role of water on and off. Water, electromagnetic inlet valve open, water injection, drainage, electromagnetic drain valve open, will draw out, laundry, wash motor startup, dehydration, to take off the bucket start.四、The fourth chapter hardware circuit design system selection(1) IO points statistics:The I/O points are PLTimer/counter: 2 b/aAnalog quantity: 100150 b/aCommunication interface: a interface general need 300 b aboveAccording to the above figure out the total number of bytes to consider increase 25% spare capacity, can estimate the user program memory capacity, so as to choose appropriate PLC memory. The system has 11 digital input point 6 digital output point, need to memory 280 b, a timer six, timer 2, need to memory and b, consider allowance needs after memory 370 b.(2) CPU function and structure choiceThe function of PLC increasingly powerful, general PLC has the switch quantity logic, timing, counting, data processing and other basic functions, some PLC can also expand all kinds of special functional modules, such as the munication module, position control module, selection consider the following: function and task adapt, PLC processing speed should meet the requirements of realtime control, PLC reasonable structure, aircraft type, and unity, online programming and offline programming choice. Fully automatic washing machine control required control function is simple, small PLC can meet the requirements.五、To sum up, bined with analysis of
