摘要
以两片AT89S52单片机为主控制器,利用单片机控制和无线传输的有关知识,结合降压、单片机最小系统和系统驱动等电路设计出一款集机车自锁、机车状态信息采集、信息传输和信息显示于一体的防公车私用系统。本设计采用模块化设计理念,电路相对简单、集成度高、易于制作、安装方便、可靠性高且价格较低,适宜大规模推广。本系统具有耐用性强、灵活性好、安全系数高、方便升级的特点,并且可安装在不同品牌的汽车上,有助于保证驾驶员的安全性。
This design with two pieces of AT89S52 microcomputer as the master controller, and uses knowledge of SCM control, wireless transmission, step-down circuit, the smallest single-chip system circuit, system driver circuit to achieve the function of prevention of the private use of office vehicles. This system holds many functions such as motorcycle self- locking, status information collection, information transmission, information display. This system uses modular design concept, and its circuits are relatively simple, high integration, easy to make and install, high reliability, low price, suitable for large-scale promotion.
