【正文】
ntegrated analysis of signal processing, and ultrasonic ranging device features. On this basis, the overall design of the system program, and finally achieved through various hardware and software modules. Experimental results show that the system software and hardware designed, antiinterference ability, good realtime, after the system expansion and upgrades, can be applied to car parking, construction sites and the location of some industrialsite monitoring, but also effectively solve the vehicle Reverse, liquid level, water depth, pipeline length measurements. Key words: ultrasonic。整個程序采用模塊化設(shè)計(jì),由主程序、發(fā)射子程序、接收子程序、顯示子程序等模塊組成。三、主要參考文獻(xiàn):1.謝自美. 電子線路設(shè)計(jì)實(shí)驗(yàn)測試[M] .武漢:華中科技大學(xué)出版社, 20222.樓然苗,20223.張齊,20224.
