The invention discloses a control method of high-altitude operation equipment. The method comprises the steps that in the descending process of a folding arm and/or a main arm, the real-time distanceS0 between a lower stand column of the folding arm and the main arm is obtained; and under the condition that 0<S0<X, the main arm is e kept in a set area. X is a set value, and the set area is an area where the distance between the lower stand column of the folding arm and the main arm is larger than 0 and smaller than the set value X. The distance between the lower stand column of the folding arm and the main arm can be detected in real time in the descending process of the folding arm and/or the main arm, and the main arm is kept in the set area according to the detected distance information, so that damage to an arm support of the high-altitude operation equipment caused by friction or collision between the main arm and the lower stand column of the folding arm is avoided.
