摘 要：冲压压力机作为汽车制造行业表面件加工的设备，具有多工况，变载荷、重载荷的特点，在零件加工过程中需要持续往复运行。随着设备的负荷不断增大使用年限地不断增长，一些大型的机械故障也因为磨损、疲劳以及维护保养不及时彻底等因素而开始出现，且出现频次逐渐增高。在既有的正常点巡检和例行检修保养的前提下，一些故障和问题仍无法及时发现或提前预判，从而造成了大量的非计划停机时间、人工成本、备件成本的投入。为此，引入了智能设备的概念，开发MDDP系统，实现设备自主监控、诊断、决策和预测。

Abstract：As a surface part processing equipment in the automobile manufacturing industry， stamping presses have the characteristics of multiple working conditions， variable loads， and heavy loads. They need to continuously reciprocate during the processing of parts. As the load of equipment continues to increase and the service life continues to grow， some large-scale mechanical failures have also begun to appear due to factors such as wear， fatigue， and lack of timely and thorough maintenance， and the frequency of occurrence has gradually increased. Under the premise of the existing normal point inspection and routine maintenance， some faults and problems cannot be detected in time or predicted in advance， which has caused a large amount of unplanned downtime， labor costs， and spare parts costs. To this end， the concept of intelligent equipment is introduced， and the MDDP system is developed to realize equipment independent monitoring， diagnosis， decision making， prediction.

Key words：press line， intelligent equipment， MDDP system， monitoring， diagnosis， decision making， prediction

1 引言

放眼整個冲压行业，由于无法实时掌握设备的运行状态，普遍存在设备维护不及时或过度维护的问题。维护不及时是指没有根据设备的特点和使用工况制定及时的维护计划，导致设备长期处于不健康的运行状态，极易出现重大异常停台。过度维护是指频繁的对设备进行保养，频繁拆装，导致设备原有配合关系和精度破坏，加快老化、失效进程。

因此，我们需要实时掌控设备的运行状态，将其运行数据可视化、趋势化、预警化，这样就可以及时、准确的进行设备维护，将异常性停台转化为预防性维修。自主开发设备监控诊断决策预测系统应运而生。
