Abstract

The present invention discloses a data transmission method, pipeline monitoring method, RF transceiver and system. The method comprises: broadcasting and transmitting, by a first radio frequency (RF) transceiver, a data transmission request, and receiving, by the first RF transceiver, a data transmission response returned by a second RF transceiver, wherein the data transmission response includes at least a local identification (ID) of the second RF transceiver as an object ID; analyzing and obtaining, by the first RF transceiver, the object ID from the data transmission response; judging, by the first RF transceiver, whether the second RF transceiver returning the data transmission response is a data receiver according to the local ID and the object ID, if so, sending data to the second RF transceiver; and repeatedly performing, by the second RF transceiver, the above operations of the first RF transceiver, until the local RF transceiver is determined to be the data receiver according to the local ID, and then the data transmission stops. The present invention solves the problem of RF transmission distance limit with the RF devices in a way of point-to-point and directional transmission, thereby realizing the long-distance data transmission at a low cost.
