哈工大毕业设计__基于LPC2131的电动车远程监控系统的

摘要

当今世界，人们在飞速创造财富和发展文明的同时，也带来了许多负面的效应，环保和能源就是其中重要的两个方面。而传统汽车的大量使用，是造成环境污染和不可再生能源巨大消耗的重要因素。电动车以其排放少、噪声低等优点正受到广泛的关注，世界各国都把电动车作为汽车工业的发展方向。因此，对电动车行驶中各项参数的监测是关系到电动车实用化、商品化的关键技术之一，对环境保护和节约能源等方面都具有重要意义。

本文采用PHILIPS公司基于ARM7TDMI-S核的LPC2131芯片为微处理器，设计了针对电动车的蓄电池电压、电流、温度和车速信息进行监测，并使用GPRS无线通信技术进行远端数据传送。LPC2131是一个支持实时仿真和跟踪的微处理器，具有流水线技术和低功耗、高性能等特点。在电动车行驶信息检测方面，选用了霍尔和热敏电阻传感器，为数据的准确采集提供了可靠措施。同时在远程端数据传输上，本系统选择了GPRS模块MC55，其尺寸小、重量轻、传输速度快等优势保证了电动车的远程监控。

Abstract

Today's world, people create wealth and rapid development of a civil the same time, also brought many negative effects, environmental protection and energy could be an important on two levels. Widely used in traditional cars is causing enormous environmental pollution and consumption of non-renewable energy an important factor. Its emissions than electric vehicles, and low noise are widespread attention, and every country in the world's electric car development as the automotive industry. Therefore, the parameters of a moving electric vehicle monitoring is related to the electric vehicle practical, commercial one of the key technologies for environmental protection and energy conservation are all so important.

In this paper, based on the ARM7TDMI-S PHILIPS company LPC2131 chip for the microprocessor core, designed for electric vehicle battery voltage, current, temperature and speed monitoring information and uses GPRS wireless communication technology for remote data transmission. LPC2131 is a real-time simulation and tracking of the microprocessor, with the assembly line technology and low power, high performance and so on. Traffic information detection in electric vehicles, the use of the Hall and thermistor sensors for accurate data collection to provide a reliable measure. At the same time data transmission on the remote side, the system selected the GPRS module MC55, its small size, light weight, fast transmission of electric cars and other advantages to ensure remote monitoring.
