电动车防盗控制系统的设计
摘 要
随着我国经济的飞速发展,电动自行车逐渐进入人们的生活,并成为城乡的主要运载工具之一,但是电动自行车被盗却屡有发生,而现在市场上有各式各样的电动车防盗报警装置出售,一些高档的智能报警器由于价格过高或者也有价格适中、质量可靠的防盗报警器出售,但是此类报警器的报警喇叭一般都只是安装在电动车身上,而完成警情传递任务的主要部件都是振动传感器,其灵敏度较高,致使一些外界环境因素,如刮风打雷,儿童嬉闹等,都有可能使其动作,并触发报警器报警,这种由于误报警带来的噪音污染常常造成不必要的扰民用户不愿意为售价仅两三千的电动车去配置,而得不到推广。种种原因使得大部分电动车用户并没有为他们的车去配备防盗报警装置,导致一些不法分子有机可乘,电动车被盗现象日益严重,由此,一种低价位、高品质,适合于普通用户的防盗报警器将是电动自行车市场翘首以盼的。
本文基于STC89S52研究的跷跷板上行进的智能电动车系统,其硬件主要STC89S52单片机最小系统板、小车左右前轮驱动电路、小车行进轨迹探测电路、角度方向检测电路、显示电路及报警电路等组成。通过软件产生PWM波控制小车速度,利用插补运算调整小车行进轨迹。经过反复分析、比较和调测。证明本系统达到了设计的要求。

Abstract
With the rapid development of China's economy, electric bicycles gradually into people's lives, and become one of the main means of urban and rural transport, but the electric bicycle stolen has occurred frequently, and now the market has a wide range of electric car burglar alarm Device sales, some high-end intelligent alarm due to the price is too high or there are affordable, reliable and reliable anti-theft alarm for sale, but the alarm alarm speakers are generally only installed in the electric car body, and the completion of police intelligence transmission task The main components are vibration sensors, the sensitivity is high, resulting in a number of external environmental factors, such as wind and thunder, children frolic, etc., are likely to make the action, and trigger the alarm alarm, this false alarm caused by noise pollution Often caused by unnecessary nuisance users do not want to price only two or three thousand electric cars to configure, and not promotion. All the reasons that most of the electric car users did not for their car to be equipped with anti-theft alarm device, resulting in some lawless elements can take advantage of the growing theft of electric cars, thus, a low price, high quality, suitable for Ordinary users of the burglar alarm will be the electric bicycle market eagerly hope.
Based on the STC89S52 research on the seesaw on the intelligent electric car system, the hardware main STC89S52 single chip minimum system board, car left and right front wheel drive circuit, car travel trajectory detection circuit, angle direction detection circuit, display circuit and alarm circuit and so on. Through the software to generate PWM wave control car speed, the use of interpolation operation to adjust the car travel track. After repeated analysis, comparison and commissioning. Prove that the system meets the design requirements.
