Beacon
The objective of the present invention is to control a beacon in a mesh beacon. A system contains a plurality of beacons which are capable of communicating with one another within a prescribed radio wave reaching distance and which transmit and receive prescribed signals, each of the plurality of beacons being disposed within the radio wave reaching distance of at least one other beacon, and a control device capable of communicating with at least one of the plurality of beacons. Each beacon is provided with: a receiving unit for receiving a signal including a setting change instruction sent from the control device; a setting unit for changing the setting value of a prescribed item in the device on the basis of the setting change instruction; and a transmitting unit for transmitting a signal including information based on the setting value changed by the setting means to the control device.
1. A beacon in a system including: a plurality of beacons enabled to perform mutual communications within a predetermined radio wave reachable distance and transmitting and receiving predetermined signals, each of the plural beacons being disposed within the radio wave reachable distance of at least one of other beacons; and a control device enabled to perform the communications with at least one of the plural beacons, the beacon comprising:
receiving unit to receive a signal containing a setting change instruction issued from the control device;
setting unit to change a setting value of a predetermined item of a self device, based on the setting change instruction; and
transmitting unit to transmit a signal containing information based on the setting value changed by the setting unit toward the control device, wherein
the receiving unit receives a signal containing a time synchronizing instruction issued from the control device,
the setting unit sets time of a timer operating in the self device to reference time, based on the time synchronizing instruction, and sets the self device in a sleep mode for a predetermined period of time,
the receiving unit receives signals from other devices when the time of the timer is within a predetermined period, and
the transmitting unit transmits the signal to other devices when the time of the timer is within the predetermined period.
2. The beacon according to claim 1 , wherein the receiving unit receives a detection signal containing detection results of physical quantities given by other sensors, and the transmitting unit transmits a signal containing the detection signal toward the control device.
