WIRELESS SENSOR NODE, SENSOR NETWORK, AND MONITOR SERVER

摘要

PROBLEM TO BE SOLVED: To automate the association of specification of a position of a wireless sensor node 100 with a monitor target to be monitored in a sensor network 990. SOLUTION: The wireless sensor node 100 transmits sensor information and positional information to a monitor server 200. The sensor node 100 is provided with a sensor communication part 130 which receives the sensor information from a sensor 183 for outputting the sensor information by monitoring the monitor target, a wireless communication part 120 for outputting various information by radio, and a self position specifying means 110 for outputting the positional information to specify the position of the sensor. The monitor server 200 manages the sensor network 990. The server is provided with a monitor data management part 210 which receives the sensor information and the positional information from the wireless sensor node 100 and stores the sensor information as monitor data of the monitor target, and a sensor node map preparing part 220 which prepares a map showing a relative position of the sensor node on the basis of the positional information of the sensor.
