    摘要:

    伴随着经济的发展和生活节奏的加快,我国汽车保有量逐年攀升,随之而来的就是逐年增加的交通事故。为了避免交通事故的发生,设计了一种超声波近距报警装置。整个系统以TI公司的16位微控制器MSP430G2553为核心,以74LS04和MAX232串联组成超声波发射电路,以CX20106A为核心构成了超声波接收电路。该装置的量程为17 cm~8 m,精确可靠,不仅可以用于汽车防撞,还可以用到诸如起重机吊臂,盲人导盲仪等防撞设备中,为我们的人身安全提供保障。

    Abstract:

    With the development of economy and the speeding up of our life, the number of cars in China is increasing year by year, which followed by the traffic accidents. In order to avoid the occurrence of traffic accidents, an ultrasonic proximity alarm device was designed in this paper. This system take MSP430G2553, a 16 bit controller of TI, as the controller. The ultrasonic transmitting circuit was formed by 74LS04 and MAX232. CX20106A was the core component of the ultrasonic receiving circuit. The measuring range of this device was between 17 cm~8 m, which is accurate and reliable. This system could be used on not only cars, but also the crane arm and guide apparatus, which can guarantee our safety.
