SENSOR MODULE, SENSOR NETWORK SYSTEM, DATA TRANSMISSION METHOD, DATA TRANSMISSION PROGRAM, AND DATA COLLECTION METHOD IN SENSOR NETWORK SYSTEM

摘要

A sensor module that transmits at a predetermined transmission interval, via a network, data obtained by measurement to an externally installed information processing device sets, together with a nearby sensor module, a predetermined module group in which a plurality of sensor modules for transmitting measurement data according to data processing in the information processing device are put together. Then, together with the nearby sensor modules, one sensor module among the predetermined module group is set as a reference sensor module for which a transmission interval is maintained at a predetermined transmission interval, and transmission intervals of measurement data of sensor modules other than the reference sensor module are changed to a prolonged transmission interval that is longer than the predetermined transmission interval. With this, a reduction in power consumption is realized as much as possible in the sensor module that measures environmental parameters and transmits to the information processing device.

1. A sensor module that transmits at a predetermined transmission interval, via a network, data obtained by measurement to an information processing device that is installed externally, the sensor module comprising:
group setting means for setting, together with a nearby sensor module located in the surroundings of the sensor module, a predetermined module group in which a plurality of sensor modules for transmitting to the information processing device measurement data according to data processing in the information processing device are put together, based on predetermined parameters that relate to measurement by the sensor module and the nearby sensor module; reference sensor module setting means for setting, together with the nearby sensor module, as a reference sensor module, one sensor module for which a transmission interval of the measurement data is maintained at the predetermined transmission interval, among the predetermined module group; and transmission interval changing means for changing, if the sensor module is a sensor module other than the reference sensor module of the sensor modules included in the predetermined module group, the transmission interval of the measurement data of the sensor module to a prolonged transmission interval that is longer than the predetermined transmission interval.
