REMOTE READING SYSTEM COUPLER

摘要

PROBLEM TO BE SOLVED: To perform the suppression of an introduction cost and the reduction of traffic by allowing a single master station to acquire measurement information from slave stations respectively connected to multiple transformers.

SOLUTION: A master station 21 and a master station side coupler 20 are connected to the secondary side of a pole transformer 41. Slave stations 11 and slave station side couplers 10 are connected to the secondary side distribution wires 33 of step-down transformers 32. Communication is performed by power line carrier communication between the master station 21 and the master station side coupler 20 and between the slave stations 11 and the slave station side couplers 10. Communication is performed by radio communication between the slave station side couplers 10 and the master station side coupler 20. The master station 21 communicates with the slave stations 11 through communication routes including radio communication passages between the slave station side couplers 10 and the master station side coupler 20, and the slave stations 11 collect reading information acquired from power meters 34.
