本文介绍上海新华气焊工具厂利用单片微机控制高温钼丝炉的经验。文章介绍的控制系统采用了Bang-Bang控制与PID控制相结合的方法,可以实现全功率升温。整个控制系统硬件成本只五～六百元左右。该系统自1985年研制成功后,至今已正常运行一年多。本文是采用电子技术改造企业老设备的一个尝试,对有关部门有参考价值。
This article introduces the Shanghai Xinhua gas welding tools factory use of single-chip microcomputer control of high-temperature molybdenum wire furnace experience. The article introduces the control system uses a combination of Bang-Bang control and PID control method, you can achieve full power temperature. The entire control system hardware costs only five to six hundred or so. After the system was successfully developed in 1985, it has been operating normally for more than one year. This article is an attempt to use electronic technology to transform the old equipment business, the relevant departments have reference value.
