  • Sensor network system
    Patent number: 9516699
    Abstract: A sensor network system is provided with a plurality of sensor terminals disposed in a predetermined area, and a monitoring center device that collects sensing data wirelessly transmitted from each of the plurality of sensor terminals. The sensor terminals wirelessly and intermittently transmit a transmission signal including sensor identification information and the latest sensing data from the sensors. The monitoring center device has the function of acquiring positional information of the sensor terminals in the predetermined area, and accumulates each item of the sensing data from the sensor terminals as time-series data in association with information about the time of acquisition. On the basis of the positional information of the sensor terminals and the time-series data of the accumulated sensing data, a time-series variation of an environmental element in the predetermined area is visually presented.
