常规仪表控制系统用于回火炉中,精度较差,难于满足热处理工艺要求。而且,每台炉子都配备一套仪表控制系统,在管理、维修和设备投资方面都有较高的要求。用微型机对回火炉实现群控,提高了控制精度和产品质量,满足了生产工艺的要求,实现了生产过程自动控制和现代化管理。一、控制系统的组成、功能及特点 1.系统组成系统由主回路、TP801单板机、TC-300显示器、SP-1000打印机、A/D、D/A转换电路等组成。其系统组成框图如图1所示。
Conventional instrumentation control system used in the tempering furnace, the accuracy is poor, difficult to meet the heat treatment process requirements. Moreover, each stove is equipped with a set of instrumentation and control systems that have high requirements in terms of management, maintenance and equipment investment. Microcomputer control of tempering furnace to achieve group control to improve the control accuracy and product quality to meet the requirements of the production process to achieve the production process of automatic control and modern management. First, the composition of the control system, functions and features 1. System Components The system consists of the main circuit, TP801 single board machine, TC-300 display, SP-1000 printer, A / D, D / A conversion circuit. The system block diagram shown in Figure 1.
