Embodiment Construction
[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] The alarm method of the present invention fully considers the development process of the overall equipment state, extracts empirical knowledge from the multi-measurement point operation history data of the equipment, and dynamically defines the range of characteristic parameter changes in the normal state of the equipment, as a basis for individualized abnormal state discrimination. Adaptive data model to automatically process and analyze the status data of field equipment, and realize abnormal alarms with higher use value and characteristics.
[0042] Such as figure 1 As shown, the alarm method of the present invention is specifically carried out in the following steps:
[0043] Step 1: Simultaneously collect the characteristic parameters of at least one measuring point reflecting the operating state of the equipment at the same samp...
