基于射频卡与USB开关量输出板的实验室管理系统

A Lab Management System Based on RF Card and USB Output Board

介绍一个由射频卡系统 ,USB开关量输出板和计算机所组成的实验室开放管理与控制系统。由射频卡系统和计算机组成信息采集系统 ,计算机通过控制柜的USB控制板 ,经USB主控芯片进行地址译码、逻辑控制 ,完成开关量的输出 ,控制每个实验台电源的开通与关闭。从而 ,实现了对所在实验室实验台的自动分配、记录、控制等功能。并对每个实验台的使用人和使用时间进行控制、查询、统计和汇总等 ,使实验室在无人值守的情况下 。

This paper introduces a lab open management and control system which consists of RF card, USB output board and computer. RF card and the computer make up of an information system. The USB control chip can accomplish the address decoding, and logic control. By the USB control board the computer can output switch signals to control the power of every equipment so that the system implements the assignment, record and control functions of lab’s equipment. This system can effectively control, retrieve, count and summarize the user’s name and usage time so the lab can be effectively managed without anybody’s duty.
