In a sensor data acquisition terminal (), an NTP back-end processing unit () synchronizes a terminal timing with a parent terminal timing by exchanging NTP packets for time synchronization with a parent terminal () based on NTP, and a protocol conversion unit () converts an NTP packet, which is output from the NTP back-end processing unit () and will be transmitted to the parent terminal (), to a TPSN packet based on TPSN, outputs the TPSN packet to a wireless processing unit (), converts a TPSN packet from the parent terminal (), which is output from the wireless processing unit (), to an NTP packet, and outputs the NTP packet to the NTP back-end processing unit ().
