摘要
为从根本上解决因使用纸质价格标签带来的商品标示与销售价格不符的问题,对电子价格标签的应用进行研究,并开发由手持装置与显示装置组成的电子价格标签演示系统。手持装置与显示装置由STC89C51单片机及相关数据处理电路,以及由红外发射管与接收管组成的红外通信电路和数码管等器件组成。该演示系统可实现百位至小数点后一位的四位数据在手持装置上的修改,并通过红外传输的方式对显示装置内数据进行远距离修改。该研究成果对促进电子价格标签技术在我国零售业中的应用与发展具有积极的推动作用。
To solve the problem of price difference between the prices of items on shelf and those at check-out point caused by using paper price labels,this paper studied the application of electronic price label,and developed a demonstration system including the handheld device and display device. The handheld device and display device are consisted of data processing circuit based on microprocessor STC89C51 RC,infrared communication circuit including infrared emitter and receiver,and other components such as LED numeric display. This demo system can modify data on the handheld device with four significant digits,and update the price data on the display device remotely through infrared transmission. The result of this paper can help to promote development and improvement of practical application of electronic price label in China＇s retail industry.
