SENSOR NETWORK SYSTEM, MOBILE BODY, AND SENSOR TERMINAL POWER FEEDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sensor network system capable of charging a sensor terminal even when an operator does not come to an installation site of the sensor terminal.SOLUTION: The sensor network system for collecting information measured by a sensor with a server 4 includes: sensor terminals 1-a to 1-f that have a power supply device and sensor, are operated by electric power supplied from the power supply devices, and transmit the sensor information measured by the sensors; a server 4 for acquiring and recording the sensor information transmitted from the sensor terminals; and a mobile body 5 for performing a moving/power-feeding operation of moving to the installation site of each sensor terminal and supplying charging electric power to the power supply device of the sensor terminal.
