| 摘 要： | 基于STC89C52单片机设计了一款低成本病床呼叫系统。使用单片机控制语音合成芯片和液晶显示模块,通过ISD1760的FT直通操作模式录制语音信息,然后利用ISD1760的SPI模式接口与单片机的I/O端口连接通信,实现单片机对语音芯片的控制。同时加入留言功能,使呼叫系统更加人性化。样机测试表明,呼叫系统的稳定性高,解决了落后地区乡镇医院中病人得到及时护理的问题。

| Abstract: | A low-cost sickbed calling-system is designed based on STC89C52. The single-chip microcomputer is used to control speech synthesize and LCD display module,and the voice massage is recorded through FT straight-through operation mode of ISD1760. Then the SPI model interfaces of ISD1760 is connected and communicated with the I/O port of single-chip mi-crocomputer to realize the control of voice chip by single-chip. The addition of the message function makes the calling system more humanized. Prototype tests show that the call system has high stability,which can solve the problems of timely care for pa-tients in backward area of township hospitals. |
