以C8051F020为核心处理器,设计无线传感器网络数据采集系统。系统采用SZ05-ADV型无线通讯模块组建Zigbee无线网络,结合嵌入式系统的软硬件技术,完成终端节点的8路传感器信号的数据采集。现场8路信号通过前端处理后,分别送入C8051F020的12位A/D转换器进行转换。经过精确处理、存储后的现场数据,通过Zigbee无线网络传送到上位机,系统可达到汽车试验中无线测试的目的。 Abstract: This paper designs a wireless sensor network system for data acquisition with C8051F020 as core processors.The system used SZ05-ADV wireless communication module,set up a Zigbee wireless network, combined with hardware and software technologies of embedded systems,completed the end-node 8-locale sensor signal data acquisition.Eight locale signals were sent separately into the 12-bit ADC of C8051F020 for conversion through front treatment.After accurate processing and storage,the locale data was transmitted to the host computer through Zigbee wireless.The system achieves the purpose of wireless testing in vehicle trial.

针对目前汽车追尾事件频发问题,提出一种防汽车车前和车后追尾的安全装置设计。该设计以高性能、低功耗的8位AVR微处理器ATmega8L为核心,结合霍尔式车速传感器、激光雷达测距装置和MMA7260QT加速度传感器,能够兼顾车前和车后,摒弃以往设计中只考虑车前或车后单一性缺点,尤其适用于高速、夜晚或新手行车。 Abstract: Aiming at the high frequency of vehicle rear-end collision,a safe device design of anti-vehicle rear-end collision is presented.In the design,the high-performance,low-power8-bit AVR microprocessor ATmega8L is utilized as a core combined with Hall-type speed sensor,laser-radar ranging devices and the acceleration sensor MMA7260QT.The design considers both the front and back of a car,and overcomes the drawbacks of former designs in which only the front or the back of the car is considered,so it is especially suitable for high-speed,night or the beginner’s driving.
