具有数据传输和来电显示功能电话机的设计

The Design of the Telephone with the Functions of the Data-transmission and Calling Identity Delivery(CID)

在来电显示电话机上增加了数据传输功能,使来电显示电话机更具实用价值。系统硬件采用台湾义隆公司的8位专用单片机EM78806B作为电话机的主控制器,该芯片附带音频拨号和LCD驱动等功能,并具有较大容量的程序存储空间和数据存储空间,使系统开发和生产成本大大降低。

Adding the data-transmission function on the CID telephone can make the CID telephone possess higher use value. In its system hardware, the eight bit special single-chip microcomputer EM78806B produced by Taiwan Yilong Company is adopted as the main controller, its chip possesses voice-dialing function and LCD driving function attached, and also possesses the program storage space and data storage space with bigger capacity, which makes the cost of the system development and production be reduced greatly.
