Along with the monolithic integrated circuit technology development,
each kind of control system all tends to the automation. By the monolithic
integrated circuit for the core control system volume small, the function
strong, the price is low, thus obtains the widespread application in the
multitudinous domain, and demonstrates the broad prospect.
This design is based mainly on STC89C51 chip core ultrasonic range
finder, and a ultrasonic processing module CX20106A, CD4069 composed
of ultrasonic transmitter, digital display devices such as composition,
including the SCM system, ultrasonic transmitter and ultrasonic receiver
circuit, MCU Resetcircuit, LED display circuit.Ultrasonic Distance and
direction to achieve the main functionality.Based on the actual
measurement accuracy can also add temperature compensation circuit.The
system cost, functional and practical.Hardware system has good
performance, and constitute a system of device applications as universal,
easy maintenance.Therefore, this design has a strong cost-effective and
practical.
