Embodiment

[0028] Embodiment: original current data set S={0.02,0.03,0.02,0.02,0.02,0.03,0.03,0.02,0.02,0.61,1.29,1.28,1.29,1.29,1.27,1.28,1.28,1.27}, after the above A After -2 processing, the final current data set P={0.02,0.03,0.02,0.02,0.02,0.03,0.03,0.02,0.02,1.29,1.28,1.29,1.29,1.27,1.28,1.28,1.27}, the reference current Data set C = {0.02, 0.03, 1.27, 1.28, 1.29}.

[0029] B. Data analysis mainly includes the following two steps to complete.

[0030] B-1. Steps for dividing the current fluctuation interval.

[0031] B-2. Step of merging current fluctuation intervals.

[0032] The main content of step B-1 is as follows: image 3 shown. The basis for dividing the current fluctuation interval is that although the current value of the instrument fluctuates in a certain state, the current fluctuation is limited and will only change within a certain range. Therefore, the current data of the instrument in different states should exist in different intervals. According to this basis...

Abstract

The invention discloses a current-based instrument state detection method. The method comprises the following steps of firstly, acquiring the current data of each instrument, and then analyzing the current data of the instruments when the main state current data of the instruments are acquired. In an analysis result, current fluctuation intervals corresponding to different states of the instrument can be seen. If the number of the current fluctuation intervals is less than 2, it is considered that the current fluctuation intervals are abnormal, and a person in charge is notified to check on site; if the fluctuation interval is equal to 2, it is considered that the instrument only has a shutdown state and a working state and does not have a standby state, and the instrument is usually an oscilloscope or an analyzer; and if the interval is greater than 2, it is considered that the current instrument has the shutdown state, the standby state and the working state. The use duration of the instrument can be calculated according to the relationship correspondence between the current fluctuation intervals and the states. By adopting the method, the use efficiency of the instrument can be effectively mastered.

Description

technical field [0001] The invention relates to the field of data analysis, in particular, the invention relates to an instrument state detection method based on current data. Background technique [0002] As an important part of national assets, scientific research instruments have become an important material basis for modern scientific exploration. As the country's investment in scientific research instruments continues to increase, scientific research institutions and personnel have also increased. However, compared with developed countries in terms of instrument use efficiency and sharing rate, there is still a big gap. In order to improve the efficiency of the instrument, it is first necessary to realize the detection of the state of the instrument. [0003] The Chinese patent application "A Big Data Analysis Method Based on Instrument Current Data" (Application No.: 201910456282.9) discloses a method for instrument state detection, which uses a support vector machine...
