基于VC++的温度控制系统设计的研究

his article describes the automatic temperature control system design and implementation process which based on the Visual C++ .Using the AD590 got real-time temperature, the output signal from AD590 goes through the signal conditioning circuit which changes the temperature signal into 0-10V voltage signal. Voltage signal communicate with the VC++ through the data acquisition card and realizing the real-time acquisition and display temperature, dynamic waveform display. Control the temperature control system with the integral separation PID. Experimental results show that the system has high precision, fast response, and practical value.
