Embodiment 1

[0037] figure 1 The power management system 10 of the present embodiment is shown, wherein the power management system 10 is configured to supply from a power source (commercial AC (alternating current) power source in this embodiment) 14 for measurement to a predetermined place via a power distribution line 5 The electric power meter 1 of the electric power amount (in this embodiment, the customer 100) collects meter reading data including the electric power amount. Note that the power source 14 is not limited to a commercial AC power source. In addition, the predetermined place is not limited to the demand side 100 .

[0038] The power management system 10 of this embodiment includes a slave machine (communication device) 2 , a host device 30 and a communication terminal (maintenance terminal) 4 .

[0039] The slave machine 2 is configured to obtain meter reading data including the power amount from the power meter 1 . Specifically, for example, as image 3 As shown, the...

Embodiment 2

[0189] The power management system 10 of this embodiment differs from the power management system 10 of Embodiment 1 in that the first interface unit 21 of the slave 2 is configured to communicate wirelessly via the first communication path 11 using radio waves as a transmission medium. The communication method communicates with the master machine 3 . Hereinafter, the same components as those of Embodiment 1 will be designated with the same reference numerals, and explanations for these components will be omitted.

[0190] In short, in the present embodiment, each of the first interface section 21 , the second interface section 22 and the third interface section 23 is configured to perform wireless communication using electric waves. Therefore, in this example, if Figure 9 As shown, the communication between the slave machine 3 and the main machine 4, the communication between the slave machine 2 and the maintenance terminal 4, and the communication between the slave machine...

Abstract

This cordless handset for a power management system is a cordless handset for a power management system for collecting meter reading data, including the amount of electricity, from an electric meter that measures the amount of electricity supplied from a power supply to a prescribed location through a power line. The cordless handset is provided with: a first interface for communicating with a higher level device, a second interface for wireless communication, utilizing radio waves, with an electrical device located at a prescribed location; and a third interface for wireless communication, utilizing radio waves, with a communication terminal. The second interface and third interface is configured to use the same communication protocol.

Description

technical field [0001] The present invention relates to a sub-unit of a power management system and a power management system, and particularly relates to a sub-unit of a power management system and a power management system having a function of transmitting meter reading data including the amount of power measured by a power meter on the demand side to a host device. management system. Background technique [0002] Conventionally, a remote meter reading system has been proposed that is configured such that a power meter measures the amount of power usage in each demand side, and a main machine (master station) obtains the measurement result from a child machine (substation) installed to the power meter as a Meter reading data (for example, see Document 1 [Japanese Laid-Open Patent Publication No. 2011-250301]). [0003] In the system disclosed in Document 1, a master computer communicates with a higher-level server (higher-level centralized server) via a communication netw...
