Abstract
A conflict resolution method for a remotely controlled device is provided. The method includes: issuing a command for the device by a remote control center or by the device; determining a criticality level of the command; depending on the criticality level of the command, sending the command to the other one of the device and the control center for acknowledgment or refusal of the command; and executing or disregarding the command by the device depending on the criticality level of the command and, if applicable, on the acknowledgment or refusal of the command.
Claims18
A conflict resolution method for a device comprising:
- issuing a command for the device by the device,
- wherein the device can issue the command on its own;
- determining, by the device in response to the command issued by the device, a criticality level of the command;
- depending on the criticality level of the command, sending the command to a remote control center for acknowledgment or refusal of the command;
- and
- executing or disregarding the command by the device depending on the criticality level of the command and based on the acknowledgment or refusal of the command;
- wherein the criticality level determines whether any acknowledgment by the remote control center is necessary before the command is executed;
- wherein issuing the command for the device by the device comprises:
- determining a control mode of the device by the device,
- wherein sending the command to the remote control center by the device further depends on the control mode of the device,
- wherein executing or disregarding the command by the device further depends on the control mode of the device,
- wherein, in a normal control mode, the device is configured to send the command to the remote control center by the device based on the determined criticality level of the command, wherein, in a priority mode of the device, the device is configured to directly execute the commands irrespective of the criticality level of the command, and wherein, in a lockout mode of the device, the command needs to be acknowledged by the remote control center irrespective of the criticality level of the command;
- in response to determining that the control mode of the device is in the normal mode and the criticality level of the command is high,
- the command from the device is executed by the device before the device receives an acknowledgment or refusal of the command from the remote control center in response to determining the acknowledgment or the refusal cannot be obtained within a specified time frame, and
- wherein, in response to the acknowledgment or refusal of the command not being received from the remote control center within the specified time frame, the command is reversed by reverting parameters of the device to the parameters before the command was executed by the device;
- and
- changing the control mode of the device by the remote control center.

A conflict resolution system, comprising:
- a device to be remotely controlled;
- and
- a remote control center,
- wherein the device is configured to:
- issue a command for the device on its own;
- determine a criticality level of the command, by the device issuing the command in response to the command issued by the device;
- and
- depending on the criticality level of the command, send the command to the remote control center for acknowledgment or refusal of the command,
- wherein the device is configured to:
- execute or disregard the command depending on the criticality level of the command and, if applicable, on the acknowledgment or refusal of the command;
- wherein issuing the command for the device comprises:
- determine a control mode of the device by the device,
- wherein sending the command by the device for acknowledgment or refusal of the command from the device to the remote control center further depends on the control mode of the device,
- wherein executing or disregarding the command by the device further depends on the control mode of the device,
- wherein, in a normal control mode, the device is configured to send the command to the remote control center by the device based on the determined criticality level of the command, wherein, in a priority mode of the device, the device is configured to directly execute the commands irrespective of the criticality level of the command, and wherein, in a lockout mode of the device, the command needs to be acknowledged by the remote control center irrespective of the criticality level of the command;
- in response to determining that the control mode of the device is in the normal mode and the criticality level of the command is high,
- the command from the device is executed by the device before the device receives an acknowledgment or refusal of the command from the remote control center in response to determining the acknowledgment or the refusal cannot be obtained within a specified time frame, and
- wherein, in response to the acknowledgment or refusal of the command not being received from the remote control center within the specified time frame, the command is reversed by reverting parameters of the device to the parameters before the command was executed by the device;
- and
- changing the control mode of the device by the remote control center.
