Embodiment

[0065] The specific implementation steps of the experimental equipment monitoring method based on power parameter monitoring and screen information identification in this embodiment are as follows:

[0066] S1: Analyze and divide the typical state of the experimental equipment to be monitored to complete an experimental process.

[0067] S2: Use the power parameter monitoring device to directly measure the voltage RMS U, current RMS I, active power P, reactive power Q, apparent power S, power factor The measurement frequency is 5 times / min, and the measurement time length is 1440 minutes, so the power parameter monitoring device needs to measure 7200 times. Finally, 7200 sets of data were obtained, each set of data including voltage RMS U, current RMS I, active power P, reactive power Q, apparent power S, power factor Denote the data of the i-th measurement as d i =(x i1 ,x i2 ,x i3 ,x i4 ,x i5 ,x i6 ).

[0068] S3: According to the 7200 groups of data measured in S...

Abstract

The invention discloses an experimental equipment monitoring method based on power parameter monitoring and screen information identification. The method comprises the following steps: a local operator analyzes and divides the typical state of the experimental equipment to complete an experimental process; Monitor the power parameters at the incoming line of the experimental equipment under different typical states for a long time, use the cluster analysis algorithm to establish the equipment state feature library; establish a neural network model, and use the power parameter monitoring device to measure the incoming line of the experimental equipment to be monitored in real time. Power parameters, predict the state of the experimental equipment to be monitored; use image recognition technology to identify the computer screen information of the experimental equipment to be monitored, analyze and judge the state of the experimental equipment; monitor the experimental equipment in conjunction with the above two judgment conditions, and analyze whether the results of the two are Consistent. The invention can realize the functions of equipment state monitoring and fault monitoring and protection for the experimental equipment of the computer experimental software with the private protocol.

Description
