八通道气体智能测控仪

8-Path Intelligent Measuring and Controlling Instrument of Gases

将单片机及计算技术引入气敏法测量中,实现了气体的多通道多功能智能测控。针对多通道结构和气敏传感器的特点,设计了多种软件,减弱了气敏测量中温漂、时漂的影响,实现了一机适用多种气体和传感器的可置换性。研制了预测技术,克服了响应中的滞后现象。仪器还具备浓度数据贮存,事故数据记忆,群控及测量传感器响应与恢复特性等功能。

Using single-chip microcomputer and computative technique on gas-sensing measurment, the intelligent measurement and control of gas with many-path and much-ability is realized. In the light of the structure of many-path and the feature of gas sensors, a great number of softwares are so designed, that the drift of temperature and time is decreased, and that adaptation of one instrument to many kinds of gases and replace ability of sensors are obtained. Through the study of forecast technique, the hysteresis phenomenon in response and restoration disappears. At the same time, the instrument has many other functions, including the store of concentration data, the memory of accident data, group control and measurement of response and restoring charactristics of sensors, etc..
