Title:
BEACON TRANSMISSION DEVICE AND NETWORK SYSTEM PROVIDED WITH THE SAME
Document Type and Number:
Japanese Patent JP2018161357
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a beacon transmission device or the like using environmental power generation, capable of transmitting the number of correct times of transmission even though a beacon reception device side cannot temporarily perform reception.SOLUTION: A beacon transmission device 10 basically includes: an environmental power generator 20 for converting dynamical energy existing in environment into power EP, and outputting the power EP when the power EP exceeds a constant value (corresponding to a first threshold V1); and a transmitter 30 for receiving the power EP outputted from the environmental power generator 20, and transmitting a beacon signal BC including a transmission count value C corresponding to the number of times of receiving the power EP and individual identification information DA by using the power EP.SELECTED DRAWING: Figure 1
