一、系统概况在我国的玻璃工业生产过程中,原料配合是一个关键环节。就我国现状,绝大多数仍沿用传统的杠杆秤。这种称量装置,不仅速度慢,精度低,而且事故率高。随着大规模集成电路和微处理机的广泛应用,数字电子秤开始问世,直至七十年代中期开始应用于工业的过程控制中,并且取得了良好的效果。我厂二号玻璃熔窑控制系统采用托莱德磅秤公司生产的数字电子秤。该系统使用十五台微处理机,其中有十台称作 First, the system overview In China’s glass industry production process, with raw materials is a key link. The current situation in our country, the vast majority still use the traditional lever scale. This weighing device, not only slow, low accuracy, and the accident rate. With the extensive application of LSIs and microprocessors, digital electronic scales began to come into being until the mid-1970s when applied to industrial process control and achieved good results. I plant on the 2nd glass furnace control system uses the scale produced by Toledo digital electronic scales. The system uses fifteen microprocessors, of which ten are called
