摘要:隨著人們對交通便利的需求，機動車輛被越來越多的使用。然而燃油交通工具在工作時必須排放尾氣，過多的機動車輛尾氣排放己造成了嚴重的空氣污染問題。于是研發(fā)綠色環(huán)保的交通工具是現(xiàn)在發(fā)展的一個必然方向。 中國是個人口大國，所以機動車輛的使用要多于他國，所以我國的空氣污染問題要更為嚴峻，所以發(fā)展電動自行車具有重要的環(huán)保意義。尤其依靠先進的科技，發(fā)展電動自行車，可以方便百姓出行，緩解城市交通擁堵，同時又能起到抑制石油使用，降低空氣污染的作用。這都具有重要的現(xiàn)實意義。所以電動自行車迅速的得到了普及。 電動自行車在不斷告訴發(fā)展的同時也遇到了發(fā)展的瓶頸。比如目前，市場上大多數(shù)的電動自行車產(chǎn)品均采用功能簡單的控制裝置。使其功能單一，不能充分發(fā)揮整個系統(tǒng)的潛力以及處理一些復雜的控制問題。本文將通過AT89C51單片機作為控制芯片設計電動自行車的控制器。次控制器可以對整個系統(tǒng)實時監(jiān)控，能夠完成很多功能，從而是使用者得到更好的騎乘體驗。 關鍵詞 電動自行車；AT89C51；控制系統(tǒng)；無刷電動機
Abstract:To fix the need of quickly transportation, all kind of vehicles are used increasingly. However, the more vehicles we used the more air pollution we created. With too much vehicle work at the same time ,it have caused serious air pollution. So the development of green transport has become a very famous topic. As we know the China is country with great population, so the use of vehicles more than other countries, so air pollution problems of China will be more severe. So the development of electric bicycles were very necessary to decrease the.air pollution. In particular, thanks to the development of the science and technology, the electric bicycles has become a very mature transport, people can easily travel and the ease urban traffic congestion, while restrain oil use, reduce air pollution effects. This has important practical significance. So it quickly gained popularity. With the development of electric bicycles , while also facing development bottleneck. Such as , electric bikes,which sell on the market,are mostly made of simple function control device. It has very simple function, which can not fully exert the potential of the whole system and to deal with some complex control problems. This article will design a controller with AT89C51 microcontroller as a control chip.Secondary controller can be real-time monitoring of the entire system, with ability to complete a lot of functionality to the user to get a better riding experience.
