Abstract
A method for limiting control of a cargo handling system may comprise receiving, by a controller of a wireless access point, a system control request from a PED. The controller may determine a number of devices currently controlling the cargo handling system. The controller may send a first control key to the PED if the number of devices controlling the cargo handling system is fewer than a threshold number of devices or the controller may send a request denied message if the number of devices controlling the cargo handling system is greater than or equal to the threshold number of devices.
Claims20
An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon for limiting control of a cargo handling system to a preselected number of devices, wherein the instructions, in response to execution by a controller of a wireless access point, cause the controller to perform operations comprising:
- receiving, by the controller, a system control request from a portable electronic device;
- determining, by the controller, a number of devices currently controlling the cargo handling system;
- sending, by the controller, at least one of a first control key or a control request denied message to the portable electronic device, wherein the controller is configured to send the first control key to the portable electronic device if the number of devices currently controlling the cargo handling system is fewer than a threshold number of allowed devices, and wherein the controller is configured to send the control request denied message to the portable electronic device if the number of devices currently controlling the cargo handling system is greater than or equal to the threshold number of allowed devices;
- resetting, by the controller, a timer to zero each time a control command including an identification key matching the first control key is received from the portable electronic device;
- and
- generating, by the controller, a second control key if the timer exceeds an inactivity threshold time.
A method for limiting control of a cargo handling system to a preselected number of devices, comprising:
- receiving, by a controller of a wireless access point, a system control request from a portable electronic device;
- determining, by the controller, a number of devices currently controlling the cargo handling system;
- sending, by the controller, at least one of a first control key or a control request denied message to the portable electronic device, wherein the controller is configured to send the first control key to the portable electronic device if the number of devices currently controlling the cargo handling system is fewer than a threshold number of allowed devices, and wherein the controller is configured to send the control request denied message to the portable electronic device if the number of devices currently controlling the cargo handling system is greater than or equal to the threshold number of allowed devices;
- resetting, by the controller, a timer to zero each time a control command including an identification key matching the first control key is received from the portable electronic device;
- and
- generating, by the controller, a second control key if the timer exceeds an inactivity threshold time.
A wireless access point system for limiting control of a cargo handling system to a preselected number of devices, comprising:
- a controller, wherein the controller is in operable communication with a power drive unit of the cargo handling system;
- and
- a tangible, non-transitory storage medium configured to communicate with the controller, the tangible, non-transitory storage medium having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising:
- receiving, by the controller, a system control request from a portable electronic device;
- determining, by the controller, a number of devices currently controlling the cargo handling system;
- sending, by the controller, at least one of a first control key or a control request denied message to the portable electronic device, wherein the controller is configured to send the first control key to the portable electronic device if the number of devices currently controlling the cargo handling system is fewer than a threshold number of allowed devices, and wherein the controller is configured to send the control request denied message to the portable electronic device if the number of devices currently controlling the cargo handling system is greater than or equal to the threshold number of allowed devices;
- resetting, by the controller, a timer to zero each time a control command including an identification key matching the first control key is received from the portable electronic device;
- and
- generating, by the controller, a second control key if the timer exceeds an inactivity threshold time.
