Title:
WIRELESS SENSOR SYSTEM
Document Type and Number:
Japanese Patent JP2020188451
Kind Code:
A
Abstract:
To provide a wireless sensor system capable of achieving long-distance and high-speed data transmission while operating with low power.SOLUTION: A wireless sensor system 10 includes: multiple sensor nodes 12 that acquires predetermined measurement data; and a relay spot 13 that receives measurement data which is relayed among the sensor nodes 12 and transmits the measurement data to a predetermined communication unit (for example, gateway 105) via an LPWA (Low Power Wide Area) communication. Between sensor nodes 12 that send and receive measurement data, a switching operation is performed to asynchronously switch between the receiving side (central) and the transmitting side (peripheral).SELECTED DRAWING: Figure 4
