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 voltage effective value U, current effective value I, active power P, reactive power Q, apparent power S, and power factor The measurement frequency is 5 times / minute, 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 includes voltage effective value U, current effective value 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 ).

Abstract

The invention discloses an experimental equipment monitoring method based on electric power parameter monitoring and screen information identification. The method comprises the following steps: enabling a local operator to analyze and divide the typical state of an experimental process completed by experimental equipment; measuring power parameters of to-be-monitored experimental equipment at awire inlet in different typical states for a long time by using a power parameter monitoring device, and establishing an equipment state feature library by using a clustering analysis algorithm; establishing a neural network model, measuring the electric power parameters at the wire inlet of the to-be-monitored experimental equipment in real time by using an electric power parameter monitoring device, and predicting the state of the to-be-monitored experimental equipment; recognizing computer screen information of to-be-monitored experimental equipment by using an image recognition technology, and analyzing and judging the state of the experimental equipment; and monitoring the experimental equipment in cooperation with the two judgment conditions, and analyzing whether the two results are consistent or not. According to the invention, the functions of equipment state monitoring and fault monitoring protection on the experimental equipment of the computer experimental software with the private protocol can be achieved.

Description

technical field [0001] The invention belongs to the field of experimental equipment monitoring and relates to an experimental equipment monitoring method based on power parameter monitoring and screen information identification. Background technique [0002] With the deepening of human exploration of space, in-depth research is urgently needed on the space environment effects of spacecraft materials, devices and their functional systems. "Space environment ground simulation device" is a national major scientific and technological infrastructure, and the construction of an internationally leading space comprehensive environment ground simulation platform to realize the simulation of the main space environmental factors and their effects is the key means to solve the above problems. [0003] In the "Space Environment Ground Simulator" national major scientific and technological infrastructure project, a large number of experimental equipment in each experimental system uses co...
