Abstract: Aiming at the problem of cable necessity and delayed alarm in traditional water supply pipelineleakage mointoring, using TI‘’s ZigBee chip CC2530 as the microprocessor and communication module, the nodesare classified as coordinator node and terminal node according to their functions. The hardware structure andsoftware signal flow of the two kinds of nodes are illustrated. The results of experiments show that the nodes runin good condition, they can form network according to the reservation network topology, transmit data steadily,expand and reconstruction network rapidly.
