Vital data collection system, vital data relay device, vital data relay system, and vital data collection method

A vital data relay system comprising:

• a first relay device and a second relay device to be carried by an actor acting in an environment not reached or not easily reached by radio waves from a mobile phone base station;
• wherein the first relay device is configured to acquire vital data measured by a sensor, transmit the acquired vital data via the mobile phone base station when wireless communication with the mobile phone base station is possible, and transmit the acquired vital data to the second relay device when wireless communication with the mobile phone base station is not possible;
• and
• wherein the second relay device is configured to transmit, by low-power long-range wireless communication, the vital data transmitted from the first relay device.

A vital data collection method for collecting vital data of an actor acting in an environment not reached or not easily reached by radio waves from a mobile phone base station, the vital data collection method comprising:

• measuring vital data of the actor, using a sensor carried by the actor;
• acquiring, using a relay device carried by the actor, the vital data of the actor measured by the sensor;
• performing first transmission, using the relay device, to transmit the acquired vital data to a collection server by low-power long-range wireless communication when wireless communication with the mobile phone base station is impossible;
• performing second transmission, using the relay device, to transmit the acquired vital data to the collection server via the mobile phone base station when wireless communication with the mobile phone base station is possible;
• and
• collecting via a network, using the collection server, the vital data transmitted from the relay device.
