Wireless control system

摘要

In a lighting system, each lamp has a wireless circuit that realizes: a time measuring unit measuring the elapsed time period since the lamp is turned on by a wall switch; a specifying unit specifying a plurality of electrical devices wired to the wall switch according to the elapsed time period measured by each time measuring unit; an identification information assigning unit assigning same identification information to the plurality of lamps specified by the specifying unit as being wired to the same wall switch; and a registration unit registering a Net-ID of a remote control.

1. A wireless control system comprising: a plurality of electrical devices each having wireless transmission and reception functions; a remote control device wirelessly connected to, and controlling driving of, the plurality of electrical devices; and a plurality of power switches wired to, and turning on or off, the plurality of electrical devices, wherein
each electrical device comprises:
a time measuring unit configured to measure an elapsed time period since the electrical device is turned on by a power switch among the plurality of power switches;a specifying unit configured to specify, from among the plurality of electrical devices, another electrical device wired to the same power switch as the electrical device, according to elapsed time periods measured by the respective time measuring units of the plurality of electrical devices;an identification information assigning unit configured to assign identification information to said another electrical device specified as being wired to the same power switch as the electrical device, the identification information distinguishing said another electrical device from electrical devices connected to any other power switch among the plurality of power switches; anda registration unit configured to register the identification information assigned by the identification information assigning unit and identification information of the remote control device in association with each other, and and the specifying unit of each electrical device includes:
a time information transmitter configured to transmit first time information to another electrical device among the plurality of electrical devices, the first time information indicating the elapsed time period measured by the time measuring unit of the electrical device;a time information receiver configured to acquire second time information from said another electrical device, the second time information indicating the elapsed time period measured by the time measuring unit of said another electrical device;a calculator configured to obtain a difference between the first time information and the second time information; anda determination unit configured to determine whether the difference falls within a reference range and, wherein, when the difference falls within the reference range, the identification information assigning unit assigns identification information of said another electrical device to the electrical device, and wherein the difference falling within the reference range is greater than −1.0 seconds and no greater than 1.0 seconds.
