摘要
以STC15F100单片机、无线数传芯片nRF905和LCD12864点阵图形液晶显示屏为核心,介绍了一种无线表决系统软硬件的设计与实现。该系统通过主控器、表决器、液晶显示终端及PC上位机控制台软件实现了对表决信息的采集、处理和显示。实践证实,该系统具有功能强、功耗低、可靠性高和安装使用方便等优点,能够满足广大中小型企事业单位民主表决的使用需要,具有较高的推广和应用价值。
On the basis of the MCU STC15F100, wireless data communication nRF905 chip and dot-matrix graphic LCD12864, the wireless voter system is developed in this paper. The design and the realize of hardware and software were presented. The system realizes the acquisition,deal and display of the voting information by the main master, voter, the liquid crystal display terminal and PC console software. Practice has proved that the system has a high value promotion and application in the enterprises and institutions for the reason which can meet the use for the democratic vote, and also has many advantages, for example, the high utilization, the low power cost, the high reliability and easy to install etc.
