The invention relates to the technical field of engineering machinery and discloses a downhill working condition identification method and system and high-altitude operation equipment. The downhill working condition identification method comprises the following steps: obtaining the driving direction of the high-altitude operation equipment; on the condition that the driving direction is moving forward, carrying out the following operations: obtaining the target revolving speed of a motor set; obtaining the actual revolving speed of the motor set; obtaining the gradient of a chassis relative tothe horizontal plane; according to the target revolving speed and the gradient of the motor set, obtaining the target current of the driver of the motor set; obtaining the actual current of the driver; and when the difference value of the actual revolving speed and the target revolving speed is equal to or greater than the threshold value of the revolving speed difference, and the difference value of the target current and the actual current is within the current difference range, obtaining a first working condition result; and the first working condition result indicates that the high-altitude operation equipment is in the downhill working condition. With adoption of the downhill working condition identification method, the downhill working condition of the high-altitude operation equipment can be timely and effectively identified and the measuring result is high in precision.
