本文提出了一种数据收集装置,该装置可由工作人员的简单操作而收集到工作现场发生的数据,如操作人员的姓名、所生产的产品数目及所用工时等。本套设备的组成是:数台简化终端机、一部最多带32台可控终端机的中央集中装置和一台与集中装置相连以记录收集数据的电传机或纸带穿孔机。集中装置以序询(Polling)控制方式从每台终端机顺序地收集数据。由于终端机有静态卡片读出器,将卡片插入读出器就能录下工作人员的姓名等固定信息,因而操作非常简单。如因传输线路发生意外或因噪音产生误码而引起设备故障,即能报警而避免错误数据。变更固件(firmware)可调整设备的功能以适应多种用途。
In this paper, a data collection device is proposed, which collects the data of the working site by the simple operation of the staff, such as the name of the operator, the number of products produced, the working hours and so on. The kit consists of several simplified terminals, a centralized central unit with up to 32 controllable terminals and a teletype or tape punch connected to the central unit to record and collect data. Centralized devices sequentially collect data from each terminal using Polling control. Since the terminal has a static card reader, the card inserted into the reader will be able to record the fixed name of the staff and other information, so the operation is very simple. As a result of transmission line accidents or noise due to noise caused by equipment failure, that can alarm and avoid the wrong data. Changing the firmware adjusts the device’s capabilities to suit a variety of purposes.
