基于WINBOND 78E52电子人体秤的设计

The Intelligent Electronic Scale of WINBOND 78E52

本设计以单片机WINBOND78E52最小系统板为核心处理单元,由键盘显示、量高、测重、电子时钟、语音播报等功能模块组成.键盘显示模块界面简洁友好、操作简单、显示醒目;量高模块由步进电机作为驱动机构,控制、计算简单,精度高;测重模块主要由电阻应变式压力传感器和LM331压频转换器组成,测量准确.语音播报模块能在测量前后温馨提示和自动播报测量数据.

The design uses the WINBOND 78E52 single chip as its central part. The system consists of a keyboard-display module, length-measurement module, weight-measurement module, an electronic clock rood ule and a voice-broadcasting module and so on. The keyboard-display module has friendly succinct interface, briefly operation and noticeable display. The weight-measurement module uses a stepper-motor as its drive machine which controls and calculates simply and has high precision. The weight-measurement module of nicety measurement consists of a pressure-sensor and LM331 which is a voltage-t.o：frequency converter. The voicebroadcasting module will friendly and automatically tell your measurement data before or after the measurement.
