There is low efficiency in safety management and a lack of overall evaluation for substation construction personnel. Thus this paper proposes a safety management and evaluation method. In addition, a corresponding safety management and evaluation system is designed. This paper describes the hierarchical structure of the system, presents an analysis of its technical content, and proposes a method of storage and management of personnel safety management information based on an index of personnel facial information. It puts forward a quantitative method for safety management indicators for substation construction personnel and a method of personnel safety evaluation. This method quantifies and comprehensively evaluates personnel safety management from five aspects: compliance with basic information of personnel, completion of safety training, compliance with safety tests, goodness of physical function indicators, and standardization of the construction process. This method improves the scientific and rationality of personnel safety management, and enhances the overall safety of substation construction.
