摘要
自主巡逻安保智能小车以飞思卡尔 MC9S12XS128 单片机为控制核心,结合数
字罗盘、超声波、摄像头、热释电、烟雾、温度等多种传感器,检测外部环境,
集智能自主导航、无人值守自动巡逻、特殊情况检测报警等功能于一身,并能够
与无线安全检查网络以及中控室进行信息交流,构成综合性的立体安全系统。
智能小车一共有两种工作模式,即自主巡逻模式和应急模式。
自主巡逻模式下。从车库出发,根据预先存储在 FLASH 存储器中的道路信息、
巡逻路径等,借助视觉系统识别路标信息,以及导航系统确定方向。对楼道进行
自主巡逻,完成对各个路段的扫描,检测区域内有无非法闯入者或者环境异常(包
括温度,烟雾浓度情况),并返回相关数据。巡逻结束自动停到车库。
应急模式。能够自动查询预存的路径信息,获得小车当前位置,并根据报警
的无线节点所发的编号信息,迅速计算出最佳路径,然后快速前往报警地点。当
到达报警路段后,对该区域进行全方位扫描。采集温度、视频等相关信息,并返
回数据。应急模式结束后,小车自动切换到自主巡逻模式。

Abstract
This security patrol car to the smart single-chip Freescale MC9S12XS128 for the
control of the core, combined with pass, ultrasonic, camera, pyroelectric,
smoke, temperature and other sensors to detect the external environment, set
intelligent autonomous navigation, unmanned Auto patrol, special circumstances,
such as detection of alarm functions, and be able work and wireless security
check in the control room, as well as the exchange of information, which constitute
three-dimensional integrated security systems.
Smart car a total of two operating modes, namely, self-patrol mode and
emergency mode.
Self-patrol mode. Starting from the garage, according to pre-stored in the
FLASH memory of the road information, such as patrol path, road signs recognition
with the visual system, as well as to determine the direction of navigation systems.
Corridor to carry out patrols on their own, completion of the various sections of the
scanning, detection of the region or whether the unusual circumstances surrounding
the illegal intruders (including temperature, smoke concentration in the case), and
return the relevant data. Automatically stop patrolling the end of the garage.
Emergency mode. Can automatically query information stored in the path to obtain
the current vehicle location and wireless node according to the police issued ID
information,
