Title: WIRELESS SENSOR SYSTEM, WIRELESS SENSOR TERMINAL, AND DATA COLLECTION METHOD
Abstract:
A wireless sensor system (10) is provided with: a wireless sensor terminal (20a to 20c) which is attached to a mobile body and which wirelessly transmits packets of data including a sense value sensed by a sensor (23a); a receiver (30) which receives the transmitted packets wirelessly; and a personal computer (40) which receives the packets from the receiver (30). The wireless sensor terminal (20a to 20c), each time the sense value is newly sensed by the sensor (23a), repeats wirelessly transmitting, by broadcast, packets of data comprising the sensed sense value, a unique data ID corresponding to the sensing, and a sense value that has been sensed in the past, a predetermined number of times at predetermined time intervals. During the repetition, each of the packets includes a transmission ID corresponding to a transmission number of times among the predetermined number of times.
