一、前言乌鲁木齐市肉联厂在冷库制冷自控技术改造中,采用了计算机这一最新电子技术。经过两年的在线控制运行,初步证明计算机控制系统性能良好,比较稳定。国产 JS—10B 小型工业控制计算机无故障连续运行时间可达300多个小时。为出厂标准时间的3倍。实践证明当控制室室温在18至34℃范围内时,计算机运行稳定。若因室温不正常,或操作有误、计算机板键接触不良、或外围设备及其接口发生障碍等因素,均能造成计算机自动停机,内存被冲等故障的发生。因此严格维护检修制度,提高操作维修水平,尚可进一步提高安全连续运行时
First, the foreword Urumqi meat factory in cold storage refrigeration control technology, using the latest computer technology electronic technology. After two years of online control operation, initially proved that the computer control system performance is good and stable. Domestic JS-10B small industrial control computer trouble-free continuous operation up to 300 hours. 3 times the standard time for the factory. Practice has proved that when the control room at room temperature in the range of 18 to 34 ℃, the computer is running stable. If the room temperature is not normal, or the operation is incorrect, poor connection of the computer board keys, or peripherals and their interface barriers and other factors, can cause the computer to automatically shut down, the memory is red and other failures occurred. Therefore, strict maintenance maintenance system, improve the level of operation and maintenance, can still further improve the safety of continuous operation
