Man-machine relationship verification method and device based on equipment use conditions

Abstract

The invention discloses a man-machine relationship verification method and device based on equipment use conditions. The method comprises the following steps: obtaining an equipment use condition database, and extracting a training set D from the equipment use condition database; extracting a feature set A of the training set D, wherein the feature set A contains features for judging the use condition of the equipment; calculating the empirical conditional entropy and the information gain of each feature in the feature set A to the training set D based on an ID3 algorithm so as to select a proper root node and a proper intermediate node; constructing a decision tree according to the selected root node and the intermediate node; and analyzing whether the equipment is frequently used or notand whether the equipment is replaced and used arbitrarily or not based on the decision tree so as to adjust and maintain the requirements of the equipment. The invention further discloses a corresponding device. Whether the equipment is frequently used or not and whether the behavior of replacing the equipment without permission occurs or not can be discovered in time through equipment feature identification calculation so that the information security and accuracy are improved, and the problems that the equipment is idle and the user of the equipment can be replaced without permission are solved.

Description

technical field [0001] The invention relates to the technical field of power grid operation and maintenance, in particular to a method and device for verifying man-machine relationship based on equipment usage. Background technique [0002] The ICT professional department is the ICT transportation inspection team, which is affiliated to the maintenance and construction work area under the Operation and Maintenance Department. In actual work, various ICT devices (especially terminal devices) are distributed widely and scattered, coupled with personnel turnover and duty changes. Due to the long-term lack of staff, the team puts more emphasis on operation and maintenance than management. The update of equipment ledgers lags behind and omissions often occur, and there is a lack of corresponding management and control methods. Especially when the company's employees are frequently transferred, there are often situations where personnel are transferred and the equipment ledger in...

Problems solved by technology

Due to the long-term lack of staff, the team puts more emphasis on operation and maintenance than management, and the update of equipment ledger lags behind, and omissions often occur, and there is a lack of corresponding management and control methods

Especially when the company's employees are frequently transferred, there are often situations where personnel are transferred and the equipment ledger information is not updated, resulting in the situation that employees are transferred without transferring equipment, equipment is mixed, and equipment is idle.
