刷卡式空调预付费控制系统的设计

摘要

为了使人们的生活更加舒适便捷，设计了一种以MSP430单片机为核心配合射频识别技术的空调预付费控制系统。系统以超低功耗的MSP430单片机为核心，从而简化了外围硬件电路的设计，包含射频读写模块、LED显示模块、键盘模块等多个组成部分。采用IAR5.0软件完成软件的编程与硬件的调试，进而实现了刷卡计费，键盘键值、余额显示等功能。%In order to make people’s life more comfortable and convenient, a air-conditioning prepayment control system with MSP430 SCM(single chip microcomputer) as the core and coordinated by RFID(radio frequency identification technology) is designed. This system takes MSP430 SCM as the core with ultra low power consumption to simplify the peripheral hardware circuit design, including RF R/W module,LED display module, keyboard module and other components. The software’s programming and hardware’s debugging are fulfilled by using IAR 5 software to realize the credit card billing,the value keying with keyboard, balance display and other functions.
