在现代大规模集成电路发展成果及微处理器价格降低的基础上,有人予言单回路微处理器控制装置(每回路一台计算机)会在不久的将来被使用(《ControlEngineering》1976年9月第123～126页)。8位的微处理器(Intel 8080片子)作为单回路比例积分反馈调节装置,通过操纵热水流动速率来调节双管路逆向流动热交换器的出口温度。通过每隔1/64秒对出口温度进行采样,并调节热水流动速率,该微处理器真正实现了与模拟比例积分调节器没有区别的温度调节与
On the basis of the development of modern large scale integrated circuits and the reduction in microprocessor prices, it was presumed that single-loop microprocessor control devices (one per circuit) would be used in the near future (Control Engineering, September 1976, p. 123-126). The 8-bit microprocessor (Intel 8080 film) acts as a single-loop proportional-integral feedback regulator that regulates the outlet temperature of the two-pipe reverse-flow heat exchanger by manipulating the hot water flow rate. By sampling the outlet temperature every 1/64 second and adjusting the flow rate of the hot water, the microprocessor truly achieves temperature regulation that is indistinguishable from the analog proportional-integral regulator
