摘要
恒温箱的工作环境对仪器的功能的实现具有重要的影响,多通道高精度温度检测系统是恒温箱控制的前端数据采集部分。本文介绍了一套针对精密仪器工作所需的环境特点设计的多通道(8路温度)高精度温度测量系统,该系统能对仪器工作环境进行测试分析,并能将测量结果通过RS232C传递给PC机,以便整个系统的准确控制。
The work condition of the incubator have great effect on its achievement of function. The system of temperature measurement with multi-channel is the data acquisition department of the whole control system ofincubator. A set of temperature measurement system with multi-channel(8 temperature channels)and high precision according to the work condition ’s character which the incubator require is described in the paper. The instrument’s work condition can be tested and analyzed and the measurement data can be transmitted to PC through RS232C for the accurate control of the whole system.
