then the current connection number of the abnormal weak current equipment and the current connection number of the weak current equipment in the equipment switching set are obtained;
subtracting the current connection number from the actual connection number to obtain the residual connection number of weak current equipment in the equipment switching set;
when the residual connection number of the weak current equipment in the equipment switching set is larger than the current connection number of the abnormal weak current equipment, subtracting the current connection number of the abnormal weak current equipment from the residual connection number to obtain the connection blank remainder of the weak current equipment in the equipment switching set, calibrating the corresponding weak current equipment in the equipment switching set to target weak current equipment if the connection blank remainder is larger than or equal to a blank number threshold value, and calibrating the corresponding weak current equipment in the equipment switching set to supplement the weak current equipment if the connection blank remainder is smaller than the blank number threshold value;
and when the residual connection number of the weak current equipment in the equipment switching set is smaller than or equal to the current connection number of the abnormal weak current equipment, calibrating and supplementing the weak current equipment corresponding to the weak current equipment in the equipment switching set.
9. The intelligent weak current equipment control system based on the internet of things according to claim 8, wherein the switching process of the intelligent switching module is specifically as follows:
if the weak current equipment in the equipment switching set is the target weak current equipment, all the electric equipment connected with the abnormal weak current equipment is switched to the target weak current equipment;
and if the weak current equipment in the equipment switching set is the complementary weak current equipment, subtracting the spare number threshold value from the remaining connection number to obtain the equipment switching number of the complementary weak current equipment until the current connected electric equipment of the abnormal weak current equipment is switched.
