Abstract

The child node device for a power management system according to the present invention is for a power management system which collects meter data including power amount from a power meter which measures the amount of power fed from a power supply to a predetermined location through a distribution line. The child node device is provided with a first interface unit for communicating with an upper level device, a second interface unit for communicating with an electrical device installed at the predetermined location, and a third interface unit for communicating with a communication terminal. The second interface unit and the third interface unit are configured so as to use mutually different schemes of carrying out radio frequency wireless communication.

Description

technical field [0001] The invention relates to a sub-machine of a power management system and the power management system. Background technique [0002] Conventionally, a power management system has been proposed in which a sub-unit for communication is installed to a power meter set in the demand side, and the sub-unit obtains meter reading data from the power meter and transfers the obtained Table data is sent to the host device. Therefore, the host device collects the meter reading data on the demand side. [0003] For example, according to the structure disclosed in Document 1 (Japanese Laid-Open Patent Publication No. 2011-250301), a host device (master station) and a slave device (slave station) perform power line transmission communication with each other by using a power distribution line as a communication path, whereby the host device Obtain meter reading data from the handset. In addition, Document 1 discloses a structure in which a slave unit and a maintenanc...
