摘要
以三菱FX2N型PLC作为下位机,以计算机作为上位机,实现了多媒体抢答器的设计。图形化编程和数据流驱动方式是LabVIEW8.6最显著的特点,为增强该装置的实用性,使用了LabVIEW8.6和Access小型数据库,用户可以在计算机上根据需要修改题库。该设计克服了常规抢答器的缺点,实现了竞赛答题的智能化管理,具有较好的人机交互界面。
Taking Mitsubishi FX2N PLC as the next bit machine, with a computer as a host computer, a multimedia responder was designed. Graphic programming and data stream driving mode were the two remarkable features of LabVIEW8. 6, so the LabVIEW8.6 and Access database were used in the system to enhance the practicality of the device, and the question database could be modified on the computer by the users. The design has overcome the weakness of the conventional rush-answer machine, realizes the intellectualized management of competition and has a good human-computer interface.
