The conventional smart meter operation state evaluation method is mainly based on the first-class reliability index,which is affected by the weight of the second-class index,and the state evaluation result has the problem of error.Therefore,the operation state evaluation method of smart meter based on improved machine is designed.The operation status evaluation indicators of smart meters is selected.The primary and secondary indicators of status evaluation are designed,and the problem of meter status evaluation errors is analyzed by means of secondary weight analysis.Based on the improved machine,the health rating of the operation state of the smart meter is established.Through the upper and lower bounds of the health rating of the operation state of the meter,the operation state evaluation of the smart meter is divided into normal,abnormal,fault and other states to ensure the accuracy of the state evaluation.Comparative experiments show that the method has higher accuracy of state evaluation and can be applied in real life.
