Power transmission and transformation equipment internet of things sensor access method and device and electronic equipment

The embodiment of the invention discloses a power transmission and transformation equipment internet of things sensor access method and device and electronic equipment. A specific embodiment of the method comprises the following steps that: a sensor to be accessed searches a plurality of aggregation nodes supporting access, and respectively sends data to the plurality of aggregation nodes; for each sink node in the plurality of sink nodes, sending a registration application to a target access node in response to the received data sent by the sensor to be accessed; the target access node determines a target sink node according to the signal strength and the routing level of each sink node in the plurality of sink nodes, and sends response information representing that the sensor to be accessed is allowed to be registered in the target sink node to the target sink node, and response information indicating that the sensor to be accessed is not allowed to be registered in the corresponding sink node is sent to ot
