引言秦皇岛市玻璃纤维厂原有一套采用TP801A的30多万元的白金钳锅计控系统,控制80台锅,每台锅约10万元,用于把玻璃球加温到1300℃进行拉丝。原来采用热电偶测温,每个约6000元,且每年更换一次,耗资较大;另外,这套计控系统也运行不稳。为解决这些问题,我们研制了不用热电偶而用下球仪信号间接判别的方法。工作的第一步就需要对TP801A进行再开发,可是用机器码及磁带机开发费时费力,有
Introduction Qinhuangdao glass fiber factory original set of TP801A using more than 30 million platinum pliers pan counter control system, control 80 sets of pots, each pot about 100,000 yuan, used to heat the glass ball to 1300 ℃ drawing. The original thermocouple temperature, each about 6,000 yuan, and once a year, costly; In addition, this set of control system is also running unstable. In order to solve these problems, we developed an indirect method to determine the signal without using a thermocouple. The first step of the job requires the re-development of the TP801A, but the development of the machine code and tape drive takes time and effort, with
