Relay terminals each transmit to a control device a packet received from a wireless sensor and a reception strength for short range wireless communication detected when receiving the packet, and return a response to the packet to a transmission source wireless sensor from which the packet is transmitted only when a response instruction is issued from the control device, and the control device compares reception strengths for a same packet that is transmitted from a same wireless sensor and received by each of the plurality of relay terminals among the reception strengths received from the relay terminals, transmits the response instruction only to one target relay terminal with the highest reception strength, and performs relay transfer of sensor data stored in a packet received by the target relay terminal to a host apparatus.
