The Design of Ward Calling System Based on SCM

Abstract:

This is a ward-called system of 64-bed. Its core component is an AT89C51 single-chip with rich internal storage resources. This system uses 8×8 matrix keyboard as its input device, a 2×8 LED as its static display, a 12MHz crystal oscillator circuit as its timer. A reset button is used to control its reset circuit. With the adoption of AT89C51 single-chip, the system has sufficient internal program memory unit and data storage unit. Therefore, there is no need for an external memory expansion with C programming language. For hospital, this is a low-cost, high-efficiency system with the advantages of easy-operation and convenient installation.
