本文介绍了TPCS-1型钨棒炉程序控温系统的软、硬件设计及其特点。该控温系统的精度为±0.2％FS,且运行可靠,编程简单,容易操作。系统具有从开环控制过渡到闭环控制自动拟合的功能。有温度越限和故障报警及打印记录和大屏幕显示。当系统的测温部分发生故障时,系统能保持在故障发生前的控制参数上,保护炉子不致损坏,解决了高温烧结炉的计算机控制问题。另外,该系统不仅适用于高温钨棒炉,而且也适用于中频炉和中、小功率的炉温控制。
This article describes the TPCS-1 tungsten rod furnace temperature control system software and hardware design and its characteristics. The temperature control system accuracy of ± 0.2% FS, and reliable operation, programming is simple and easy to operate. The system has the function of automatic fitting from open-loop control to closed-loop control. There are more temperature and fault alarm and print records and large-screen display. When the system temperature measurement part of the failure, the system can maintain the parameters before the failure of the control, the protection of the stove will not be damaged, to solve the high temperature sintering furnace computer control problems. In addition, the system is not only suitable for high temperature tungsten rod furnace, but also for medium frequency furnace and medium and low power furnace temperature control.
