液压传动与控制系统的应用领域逐年扩大,但运转中液压系统的监测,目前还基本上停留在人工巡回检测和定期检修的水平上。由于近年微机发展迅速,价格逐年下降,因而为液压系统在线监测和故障早期诊断提供条件。液压系统的故障早期诊断实际是液压系统的监测与微机在线应用的结合物,也是液压CAT 技术的扩大应用。发展人工智能系统(软件)代替人对巡回检测到的系统中各有关物理量的变化进行
The field of application of hydraulic transmission and control system has been expanding year by year, but the monitoring of hydraulic system in operation is still basically on the level of manual circuit inspection and periodic maintenance. As the rapid development of computer in recent years, the price declines year by year, thus providing the conditions for on-line monitoring of hydraulic system and fault diagnosis. Hydraulic system fault diagnosis is actually the early diagnosis of hydraulic systems and computer applications online combination, but also the expansion of hydraulic CAT technology applications. Development of artificial intelligence systems (software) instead of people on the tour detected the system changes in the relevant physical quantities
