Intelligent Ultrasonic Hardness Measuring Instrument Developed

The Exploitation of Intellectualized UltrasonicDevice of Measuring RigidityMajor: Mechanical Manufacturing and AutomationPostgraduate Cai Peng Supervisor Huang Cheng-XiangAbstract The ultrasonic technology has been wildly used in industry The ultrasonictechnology is introduced to the measurement of mechanical paramoter in material toeffectively resolve the problem of measurement of surface rigidity in material byadopting the technology of sensor, computer science and Micro-Electronic science.The device developed can meet the demands of modern measuring technology, suchas more precision, more reliability and reducing the error made by man. It also meetsthe demands of portable, flexible and convenient usage in industrial produce byutilizing Liquid Crystal Display (LCD), Integrate Circuit and modern craftwork. Theprogress of eXPloitation not only fully exploits the device but also makes an effeCtivediscussion and research for the advanced exploitation in the future.The main results of this paPer are as fellows f1) Illtroducing the ultrasonic technology to the rigid measurement, successful1yexploits the practical small intellectualized ultrasonic device of measuringrigidity by aPplying mechanical technology, electronic technology andcomputer science2) Reading clearCf displaying more various, applying more information, beingeasiest to accept by user because of adopting Liquid Crystal Display(LCD)3) Theorizing the mathematical model between the signal of frequency and therigid value on the device, possessing very importan practical significance4) Optimizing the every parts of the device, achieving the goals of lower waStageof energy, smaller, lighter and inexpensive5) Taking the measure to reduce the wastage of energy and adopting reasonablemanagement in power supply for the device, making the device skimp moreenergy, prolonging the life-span of battery6) Utilizing the interface of RS-232, discussing the communication between theultrasonic device of measuring rigidity and computef, and also forecaSting theforeground of advanced eXPloitation by user.
