：介绍一种无人值守的停车场管理系统的设计。该系统前端主要由GsM 短信模块TC35i和AVR 单片机At― megal6组成，安装在停车场的每个进出口，通过接收车主的手机短信控制进出口道闸的开启并由短信扣取停车费用，各进出 口电路都与监控中心计算机连接。-: A unmanned car park management system design. The system front-end GsM messages by AVR module TC35i and At-megal6 composed of single-chip installed in the parking lot of each import or export through SMS to receive the owner to control the import and export of道闸open parking fees deducted by SMS , the import and export of circuits are connected with the monitoring center computer.

按键扫描 51单片机加8279 8279通过74LS 138译码器扩展4×4键盘、6位显示器。 由3-8译码器对SL0～SL2译出键扫描线，由另一3-8译码器译出显示器的位扫描线，并采用了编码扫描方式。 为了防止出现重键现象，扫描输出线高位SL3不参加键扫描译码。CPU对8279的监视采用了查询方式，故8279的中断请求信号IRQ悬空未用。 -Scan button 82,798,279 plus 51 single-chip decoder 74LS 138 through the expansion of 4 × 4 keyboard, the display 6. From 3-8 decoder SL0 ~ SL2 translated to the key scanning line, by another 3-8 decoder translated display scan line, and uses code scanning. In order to prevent the emergence of the phenomenon of re-key, scan the output line does not take part in high level SL3 scan decoding keys. CPU on the 8279 surveillance using the query mode, the 8279 interrupt request signal IRQ left unused.

实时时钟芯片DS1302采用串行接口，只需3根引脚便可以完成操作，其使用非常方便。这里采用AT89S52单片机作为外部微处理器，来对DS1302进行控制-Real-time clock chip DS1302 serial interface, only three pins will be able to complete the operation, its use very convenient. AT89S52 microcontroller used here as an external microprocessor to control of the DS1302
