The invention discloses an elevator stopping detection method based on a multi-sensor confidence vote mechanism. The method comprises the steps that first, sensor sets are mounted on a shaftway and an elevator car, and each sensor set comprises a rotary encoder, an infrared sensor and RFID equipment; second, detection is conducted, the total confidence degree of the sensor sets is calculated to be equal to the sum of the statistical confidence degree and the change confidence degree, then through the comparison judgment of the total confidence degrees under the in-place state and the non-in-place state of the elevator car, positioning is obtained respectively, an elevator door is opened accurately, then an elevator continuously operates until positioning is successful, and a maintenance early warning is given out. According to the invention, based on the working principle of the rotary encoder, supplemented by the combination usage of the infrared sensors and the RFID equipment, a voting mechanism and a confidence degree changing mechanism are introduced at the same time to achieve the stopping detection of the elevator, so that the accuracy, operation safety and reliability of elevator stopping are improved; false alarm errors are basically eliminated, a timely early warning can be provided when the confidence level of the positioning sensors is too low, and it is guaranteed that maintaining is efficient.
