Abstract
A wireless lockout-tagout state machine-based access control system and method. Embodiments of the present disclosure provide for an electronic access control system that utilizes state machine-based single or multiple access codes to enable context-dependent or context-specific user-access permissions for different access points within an access-controlled area. Each state in the state machine may comprise an access event and a first state can lead to one or more subsequent different states, which may enable a feedback loop back to a past state to ensure a sequence of access events. In certain embodiments, the sequence of access events may be configured to ensure one or more safety protocols or parameters.
Claims13
An electronic access control method comprising:
- generating, with at least one processor, at least one electronic access control code associated with one or more electronic access control devices;
- configuring, with the at least one processor, a state machine model for the one or more electronic access control devices,
- wherein the at least one electronic access control code comprises at least one input in the state machine model,
- wherein the state machine model comprises one or more states, each state in the one or more states corresponding to a status of the one or more electronic access control devices;
- providing, with the at least one processor, the at least one electronic access control code to a client device;
- providing, with the client device, the at least one electronic access control code to a first electronic access control device;
- receiving, with the at least one processor, access event data for the first electronic access control device;
- in response to the access event data, effecting, with the at least one processor, at least one state transition in the state machine model;
- and
- based on the at least one state transition, enabling the at least one electronic access control code to unlock a second electronic access control device.
An electronic access control system comprising:
- a processor;
- and
- a non-transitory computer readable medium communicably engaged with the processor and comprising instructions stored thereon that, when executed, command the processor to perform one or more operations, the one or more operations comprising:
- generating at least one electronic access control code associated with one or more electronic access control devices, wherein the one or more electronic access control devices are configured to selectively grant or restrict access to at least one asset at an access-controlled site;
- configuring a state machine model for the one or more electronic access control devices,
- wherein the at least one electronic access control code comprises at least one input in the state machine model,
- wherein the state machine model comprises one or more states, each state in the one or more states corresponding to a status of the one or more electronic access control devices,
- wherein the state machine model is configured to configure at least one condition for the at least one electronic access control code according to the one or more states;
- providing the at least one electronic access control code to a client device, wherein the at least one electronic access control code is configured to unlock a first device in the one or more electronic access control devices according to the state machine model;
- receiving access event data for the first device in the one or more electronic access control devices;
- and
- effecting at least one state transition in the state machine model in response to the access event data for the first device,
- wherein the state machine model is configured to enable the at least one electronic access control code to unlock at least one second device in the one or more electronic access control devices based on the at least one state transition.
