【摘要】 传统的会议选票系统大部分都是基于RS232总线或者CAN总线的结构,这种总线结构限制了与会人的空间自由,而且整个选票系统的布线复杂,硬件成本高,系统扩展、升级和维护比较困难。论文介绍了基于高速率无线数传模块PTR2000的无线选票系统的设计与实现,该系统克服了传统的会议选票系统的缺点,具有系统扩展、维护、升级简单等特点。更多还原

【Abstract】 Most of traditional voting systems are based on RS232bus or CAN bus which limit the free space of the meeting-participator.Moreover,the whole system has many defects such as the complexity of routining wire,high cost of hardware and the difficulties of maintaining,extending and upgrading system.This paper introduces the wireless voting system which is based on PTR2000.The whole system gets over the defects of traditional voting system and has many advantages such as the simplicities of maintaining,extending and upgrading voting system and so on.更多还原
