一、智能化是仪器仪表发展的主流近年来随着微电子技术迅猛发展和微处理机广泛应用,仪器仪表技术发生了深刻变革。主要表现在:1.产品更新周期加快。并主要靠采用新型电子器件实现更新换代;2.系统性日益增强,可靠性日益提高。仪器仪表的平均无故障时间(MTBF)国外已达10—30万小时;3.微型计算机及微处理器应用于仪器仪表效果显著:节约工时5—10倍,降低成本2—6倍,可靠性提高5—10倍,能耗降低10—20倍。一般认为,电子化和微机化是近十余年仪器仪表技
First, the intelligence is the mainstream of instrumentation development In recent years, with the rapid development of microelectronics and microprocessor widely used, instrumentation technology profound changes have taken place. Mainly in: 1. Product update cycle to speed up. And mainly rely on the use of new electronic devices to achieve replacement; 2. Systematic increasingly strong, increasing reliability. Mean time between failures (MTBF) of instruments and meters has reached 10-30 million hours in foreign countries; 3. Microcomputers and microprocessors have significant effects on instrumentation: saving 5-10 times working hours, reducing costs by 2-6 times, and reliability Increase 5-10 times, reduce energy consumption 10-20 times. Generally believed that the electronic and computerized instrument technology is more than 10 years
