为适应城市供水系统集中监视控制的需要,我所曾与北京自来水公司合作,于75年12月研制出MOS集成电路的MYD-Ⅰ型远动装置(见本刊1977年第3、4期),该装置的正式产品已在北京自来水公司正常运转了二年。为适应目前国内分散型的油井、水井等生产现场的需要,又研制出MOS集成电路的MYD-Ⅱ型远动装置,试验样机曾于77年11月在沈阳市自来水公司一水厂试验运行,经1200次遥控、105次电话呼叫并通话以及八次高压模拟雷电波冲击信道的防雷试验,均取得较为满意的试验效果,达到了设计要求并于今年正式投产,首批产品将用于沈阳市自来水
In order to meet the need of centralized monitoring and control of urban water supply system, I worked with Beijing Water Company to develop a MYD-Ⅰ type remote device for MOS integrated circuits in December 75 (see No. 3,4 in 1977) , The device’s official product has been in normal operation of Beijing Water Company for two years. In order to meet the current decentralized wells, wells and other production needs of the site, but also developed a MOS integrated circuit MYD-Ⅱ-type remote device, the pilot prototype was in November 77 in Shenyang City Water Company trial operation of a water plant, After 1200 times of remote control, 105 telephone calls and calls and lightning test of eight high-voltage simulated thunder and lightning impact channels, satisfactory results were obtained, the design requirements were met and the project was put into operation this year. The first products will be used in Shenyang City tap water
