摘要
运用超声波无损检测原理,并根据牛奶液体中各种成份及含量与超声波在其中的传播时间的函数关系,基于单片机AT89S51与复杂可编程逻辑器件(CPLD),配以独特设计的超声波换能器的发射电路和接收电路,设计了一台高精度智能型超声波牛奶检测仪。
Because of there existing the relation between the composition and content of milk and the ultrasonic transmitting time through it, applysing the ultrasonic lossless survey theory, this paper designs a high precision intelligent ultrasonic milk survey meter, based on single chip microcomputer and complex programming logic device（CPLD）, cooperating with unique design the piezoelectric transducer circuit of transmitting and take over.
