Title:
POWER MEASUREMENT SYSTEM
Document Type and Number:
Japanese Patent JP2018146411
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power measurement system with which it is possible to improve the success rate of transmission of an address setting signal to a plurality of sensor units from a power measurement unit at startup of the plurality of sensor units.SOLUTION: A sensor unit 1 of a power measurement system 100 includes a first communication part 4 for transmitting a request signal SN1 to a power measurement unit 2 and an address setting part 12 for setting address information on the basis of an address setting signal SN2. The power measurement unit 2 of the power measurement system 100 includes a second communication part 6 for transmitting the address setting signal SN2 to the sensor unit 1. The sensor unit 1 starts up at a first point of time after the lapse of a first duration of time since supply of operational power is initiated. The power measurement unit 2 transmits the address setting signal SN2 to the sensor unit 1 during a monitoring period after the lapse of the first point of time and, upon receipt of the request signal SN1 after the monitoring period, transmits the address setting signal SN2 to the sensor unit 1 that is the sender of the request signal SN1.SELECTED DRAWING: Figure 1
