[PROBLEMS] To easily use a new type of sensor node and adopt a new communication standard in an existing sensor network system while effectively using limited resources of wireless communication. A sensor node SN1 includes a wireless communication unit SRF that transmits a measurement value detected by a sensor SS and an identifier of the sensor node as binary sensing data, and a base station BST receives sensing data from the sensor node SN1. The wireless communication control unit BRF that receives the data, the wired communication control unit BNIC that transmits the received sensing data to the server SNS, and the conversion definition information corresponding to the identifier included in the sensing data from a plurality of preset conversion definition information A conversion definition information selection unit that converts the binary sensing data into text sensing data based on the selected conversion definition information, and the server SNS receives the text sensing from the wired network. Has database DB to store data That. [Selection] Figure 1 |
