传统的测温方法不能对高温物体进行测量,但是不同温度下物体的热辐射特性不一样,因此可以根据测量辐射光线来计算物体的温度.比色测温通过两个不同波长光的辐射强度来计算物体的温度,减小了发射率以及信号传输等因素造成的误差.采用虚拟仪器技术开发测量系统可以大大缩减开发周期,同时也可以提供良好的人机交互界面.在虚拟仪器技术平台上开发的比色测温系统不仅能对温度实行实时监控,还能够通过以太网接口接入网络,传输温度数据和控制信号.%The traditional temperature measurement methods arc not suitable for high-temperature objects. However, objects at different temperature have different characteristics of thermal radiation, so it is a practical approach to calculate the temperature of the object according to the radiation light. The colorimetric temperature measurement is calculated by radiation intensity of two different wavelengths lights, and it reduces the errors which are created by the emission rate and signal transmission. It can greatly reduce the development cycle and provide a good interactive interface by using the virtual instrument for development of measurement system. The colorimetric temperature measurement which is developed on the virtual instrument technology platform not only implement real-time monitoring of temperature, but also transfer temperature data and control signals by accessing network via Ethernet interface.
