Reliability monitoring method based on SPC

The invention discloses a reliability monitoring method based on SPC. The method comprises the steps: presetting the set operation parameter information of each piece of equipment so as to form an original data tracing record; collecting real-time operation parameter information of each device to form a real-time data tracing record; comparing the original data traceability record with the real-time data traceability record; if the parameter difference between the original data traceability record and the real-time data exceeds a set parameter change value, carrying out reminding operation. Data is collected and analyzed by adopting an SPC technology, so that automatic statistics and analysis of equipment operation parameters are realized, and the operation reliability of an automatic production line is improved. 本发明公开一种基于SPC的可靠性监控方法，包括：预设各个设备的设定运行参数信息，以形成原始数据追溯记录；采集各个设备的实时运行参数信息，以形成实时数据追溯记录；对比原始数据追溯记录和实时数据追溯记，若原始数据追溯记录和实时数据的参数差值超出设定参数变化值时，则进行提醒。通过采用SPC技术采集数据并分析，以实现自动统计分析设备运行参数以提高自动化生产线运行可靠性。
