Abstract
With the development of electronic technology, especially with large scale integrated circuit, to the life of people brought the fundamental changes, if the microcomputer that modern science research is a qualitative leap, SCM is to appear modern industrial control measurement field brings a new revolution. Because of its small bulk and strong function, high performance-cost ratio, so widely applied in electronic instrument, electrical appliances, energy-saving equipment, military equipment, robots, industrial control and so on many domains, make product miniaturization, intelligent, improve the quality and function of products, and reduce the cost, simplified the design. This paper presents the hand-held transcribing method to realize functions, and the function of design scheme, design the hardware circuit. The hardware circuit with AT89C51, zlg7289A buttons group integrated chips as man-machine interface, and adopting new circuit chip (including the great capacity data storage DSl245, LCD SMS0823) design the hardware circuit with copy, and design a hand-held transcribing the printer interface and RS232 communication interface, which can simplify the circuit, reducing the volume, with copy software realization process. Design with AT89C51, using a variety of new integrated circuit chips (including energy metering CS546OA special-purpose chip DS1302 calendar, clock, SMS0601 / LCD, X5045 serial storage) interface design, simplified the hardware circuit and improve the anti-interference ability and electric measurement accuracy.
