Document Type and Number:
Japanese Patent JP2010141469
Kind Code:
A
Abstract:
To provide a system for changing operation states, such as on-off of power supply of a node driven by a battery disposed on a sensor network system.
In the sensor network system, a router is provided between a node for transmitting a sensed signal of a sensor and a base for receiving a data frame of the sensor from the node, human body communication is used for transmitting the data frame from the node to the router, and a conventional radio is used to transmit the data frame from the router to the base. Operation states, such as switching on and off a power supply of the node, are performed by a signal from the router.
