Information processing method, information processing device, and recording medium

An information processing device implementing any one of at least one front-end in an information processing system, the information processing system assisting at least one operator in remote control for a plurality of moving bodies, the moving bodies each being configured to autonomously move and execute a predetermined task, the information processing system including the at least one front-end, a plurality of edges, and a back-end, the front-end acquiring an operation of the at least one operator, the edges including the moving bodies, the back-end being communicably connected to the at least one front-end and each of the edges, the information processing device comprising:

• a memory in which a computer program is stored;
• and
• a hardware processor connected to the memory and configured to perform processing by executing the computer program, the processing including:
• acquiring an operation of the operator;
• executing any one of transmission modes in accordance with the acquired operation of the operator, the transmission modes being
• a first transmission mode in which a target moving body among the moving bodies is remotely monitored by transmitting an image related to the target moving body from the corresponding edge to the front-end,
• a second transmission mode in which control of the target moving body is remotely instructed by transmitting a single travel instruction signal to the target moving body, and
• a third transmission mode in which the target moving body is remotely controlled by transmitting continuous control signals to the target moving body;
• and
• periodically transmitting, to the back-end in the second transmission mode and the third transmission mode, a notification signal that is different from the travel instruction signal and the control signal, the notification signal being monitored by the back-end, the target moving body being stopped when a delay occurs in a cycle of the notification signal.

A non-transitory computer readable recording medium on which programmed instructions executable by a computer are recorded, the computer implementing any one of at least one front-end in an information processing system, the information processing system assisting at least one operator in remote control for a plurality of moving bodies, the moving bodies each being configured to autonomously move and execute a predetermined task, the information processing system including the at least one front-end, a plurality of edges, and a back-end, the front-end acquiring an operation of the at least one operator, the edges including the moving bodies, the back-end being communicably connected to the at least one front-end and each of the edges, the programmed instructions causing the computer to perform processing, the processing including:

• acquiring an operation of the operator;
• executing any one of transmission modes in accordance with the acquired operation of the operator, the transmission modes being
• a first transmission mode in which a target moving body among the moving bodies is remotely monitored by transmitting an image related to the target moving body from the corresponding edge to the front-end,
• a second transmission mode in which control of the target moving body is remotely instructed by transmitting a single travel instruction signal to the target moving body, and
• a third transmission mode in which the target moving body is remotely controlled by transmitting continuous control signals to the target moving body;
• and
• periodically transmitting, to the back-end in the second transmission mode and the third transmission mode, a notification signal that is different from the travel instruction signal and the control signal, the notification signal being monitored by the back-end, the target moving body being stopped when a delay occurs in a cycle of the notification signal.
