Sensor system, wireless cooperative receiving system, and wireless cooperative receiving method

A wireless cooperative reception system comprising:

• a plurality of relay terminals, each of the plurality of relay terminals being configured to receive a wireless packet transmitted from one or more wireless terminals using Bluetooth wireless communication;
• and
• a control device that is connected to the plurality of relay terminals by a communication line and that is configured to control an operation of receiving the wireless packet in the plurality of relay terminals;
• wherein each of the plurality of relay terminals is further configured to:
• detect a reception strength pertaining to the Bluetooth wireless communication when the wireless packet is received;
• store the reception strength in a first HCI packet;
• transmit the first HCI packet to the control device;
• and
• return a response to the wireless packet to a source wireless terminal that is a source of the wireless packet only when a second HCI packet is received from the control device;
• and
• wherein the control device is further configured to:
• compare reception strengths received through first HCI packets from the plurality of relay terminals, that pertain to the wireless packet transmitted from a same wireless terminal of the one or more wireless terminals and received by each of the plurality of relay terminals;
• and
• transmit the second HCI packet to only one target relay terminal of the plurality of relay terminals having a highest reception strength among the reception strengths received through the first HCI packets.

A wireless cooperative reception method used in a wireless cooperative reception system including a plurality of relay terminals and a control device connected to the plurality of relay terminals over a communication line, the method comprising:

• a reception step, by each of the plurality of relay terminals, the reception step comprising receiving a wireless packet transmitted from one or more wireless terminals using Bluetooth wireless communication;
• and
• a control step, by the control device, the control step comprising controlling a reception operation of the wireless packet in each of the plurality of relay terminals,
• wherein the reception step further includes:
• detecting a reception strength pertaining to the Bluetooth wireless communication when the wireless packet is received;
• storing the reception strength in a first HCI packet;
• transmitting the first HCI packet to the control device;
• and
• returning a response to the wireless packet to a source wireless sensor that is a source of the wireless packet only when a second HCI packet is received from the control device, and
• wherein the control step further includes;
• comparing reception strengths received through first HCI packets from the plurality of relay terminals, that pertain to the wireless packet transmitted from a same wireless terminal of the one or more wireless terminals and received by each of the plurality of relay terminals;
• and
• transmitting the second HCI packet to only one target relay terminal of the plurality of relay terminals having a highest reception strength among the reception strengths received through the first HCI packets.
