1. An agricultural ground work vehicle monitoring system comprising:
a work vehicle capable of automated travel, including:
a satellite positioning apparatus;
a monitoring camera;
a vehicle wireless communicator to perform Wi-Fi communication, the vehicle wireless communicator including an antenna; and
an automated travel controller;
a monitoring terminal including:
an operation interface to be operated by a monitoring person;
a monitor capable of displaying a shot image of the monitoring camera; and
a terminal wireless communicator to perform Wi-Fi communication, the terminal wireless communicator including an antenna; and
a relay apparatus configured or programmed to relay Wi-Fi data communication between the vehicle wireless communicator and the terminal wireless communicator,
the relay apparatus being movable to different locations on a field and including an antenna; wherein
the monitoring terminal is configured or programmed to:
control the monitor to indicate a first reception sensitivity indicating a strength of wireless signals between the terminal wireless communicator and the vehicle wireless communicator, a second reception sensitivity indicating a strength of wireless signals between the terminal wireless communicator and the relay apparatus, and a third reception sensitivity indicating a strength of wireless signals between the relay apparatus and the vehicle wireless communicator;
acquire the third reception sensitivity through the data communication from at least one of the vehicle wireless communicator and the relay apparatus; and
calculate a recovery measure for sensitivity recovery in response to detection of at least one of the first reception sensitivity, the second reception sensitivity, and the third reception sensitivity decreasing to less than or equal to a predetermined level.
