摘　　要：为解决有线表决系统布线繁琐、移动性差以及基于443 MHz无线表决器存在抗干扰能力较差、功耗偏高等问题,提出基于n RF24LE1无线收发模块的无线电子表决系统解决方案。该系统通过主机、大屏幕显示器、通信主站、无线投票表决器实现了对表决信息的采集、处理和显示。通信主站与主机通过RS-485串行总线相连,主要接收从PC发出的指令,根据指令通过无线模块部分向表决器发出相应的命令。通信主站将选举信息广播给表决器,表决器将表决结果信息发回给通信主站,通信主站对表决信息进行汇总并发给主机,最终主机将最终表决结果的信息显示在与主机相连的大屏幕显示器上。实验结果表明,基于n RF24LE1的无线表决器能满足无线表决器的需要,同时相比基于WAP300C无线表决器具有更好的抗干扰能力和更低的功耗。In order to solve the problem that the wired voting system has complicated wiring, poor mobility, and poor anti-jamming capability and high power consumption based on 443 MHz wireless voting device, a wireless electronic voting system solution based on n RF24 LE1 wireless transceiver module was proposed. Through the host, large-screen display,communication master, wireless voting device, the proposed algorithm was used to achieve the collection, processing and display of the voting information. The communication main station were connected with the main engine through the RS-485 serial bus, mainly received the instruction sent out from the PC, and according to which sent the corresponding command through the wireless module part to the voting machine. The communication main station broadcasted the voting information to the voting device, and the voting device sent the voting result information back to the communication main station. The communication main station collected the voting information and sent it to the host computer, and finally the host displayed the information of the final voting result on the large screen display connected to the host. The wireless voting device based on n RF24 LE1 was proved to meet the needs of wireless voting devices by practical operations, and had better anti-jamming capability and lower power consumption than the wireless voting machine based on WAP300 C.
