Beschreibung
Zusammenfassung:	The invention discloses a fan blade joint surface state monitoring method, system and device and a medium, and relates to the technical field of wind power, in order to monitor the state of a fan blade joint surface in time, a ladder-shaped resistance net is laid on the joint surface, the ladder-shaped resistance net is composed of a plurality of resistors, and if the state of the fan blade joint surface is normal, the ladder-shaped resistance net can be used for monitoring the state of the fan blade joint surface. If yes, all the resistors in the current ladder-shaped resistor net are connected in parallel, so that in order to monitor whether the state of the fan blade joint surface is normal or not, the current total resistance value of the resistors connected in parallel currently in all the resistors needs to be determined, and whether the state of the fan blade joint surface is normal or not is judged by judging whether the current total resistance value after parallel connection meets a preset condition
