The invention discloses an attitude sensor-based isolating switch opening and closing position detection and double confirmation detection method and system and a medium. The double confirmation method of the invention includes the following steps of after an isolating switch is opened/closed, obtaining the opening and closing position of the isolating switch through opening/closing auxiliary contacts to form a first criterion; recording the opening/closing actual angle of the isolating switch in the opening/closing process by using an attitude sensor, comparing the opening/closing actual angle with a preset opening/closing reference angle, and determining the opening and closing position of the isolating switch to form a second criterion; and performing double confirmation according to the first criterion and the second criterion to determine the opening and closing position of the isolating switch. According to the scheme of the invention, after the operation of the isolating switch,operation and maintenanc
