Wind pressure adjusting method and system of wall-climbing robot and wall-climbing robot

The invention discloses a wind pressure adjusting method and system of a wall-climbing robot and the wall-climbing robot, and belongs to the technical field of wall-climbing robots. The method comprises the steps that the current air pressure value of a negative pressure cavity of the wall-climbing robot and the inclination angle of an adsorption wall face are collected, and the pressure intensity values of the adsorption wall face to the uppermost end and the lowermost end of a crawler belt on one side of the wall-climbing robot are obtained; the weight value and the gravity center position of the wall-climbing robot are calculated, and the friction coefficient is determined according to the material of the adsorption wall surface; according to the inclination angle and the pressure intensity value of the adsorption wall surface, the weight value and the gravity center position of the wall-climbing robot and the friction coefficient, a safe wind pressure value currently needed by a negative pressure cavity i
