LANYARD DETECTION SYSTEM
Systems, methods, devices, and computer-readable media for lanyard detection applications. A lanyard attachment assembly may include a moveable element configured to be displaced in response to attachment of a lanyard device such that one or more sensors detect the attachment. In response to one or more operator inputs, an alert may be generated if determined that a lanyard device is not attached.
1 - 20 . (canceled)
21 . A lanyard attachment assembly for detecting an attachment of a lanyard device at a utility platform of an aerial device, the lanyard attachment assembly comprising:
at least one fixed element operable to receive the lanyard device;
a moveable element that is displaced when the lanyard device is attached to the at least one fixed element; and
an attachment sensor that determines a state of the lanyard device responsive to detecting a position of the moveable element,
wherein the lanyard attachment assembly is in a first state when the lanyard device is not attached to the lanyard attachment assembly and the lanyard attachment assembly is in a second state when the lanyard device is attached to the lanyard attachment assembly.
22 . The lanyard attachment assembly of claim 21 , further comprising:
spring element coupled to the moveable element, wherein the moveable element is biased into a closed position by the spring element when the lanyard device is not attached.
23 . The lanyard attachment assembly of claim 22 , wherein the spring element comprises a torsion spring.
24 . The lanyard attachment assembly of claim 23 , wherein the attachment sensor comprises at least one magnetically actuated reed switch operable to detect a magnetic component disposed on the moveable element.
25 . The lanyard attachment assembly of claim 23 , further comprising:
a compliant hinge component coupled to an end of the moveable element.
26 . The lanyard attachment assembly of claim 21 , wherein the first state is associated with an open position of the moveable element and the second state is associated with a closed position of the moveable element.
27 . The lanyard attachment assembly of claim 21 , wherein the moveable element comprises a spring steel material.
28 . A system for detecting an attachment of a lanyard device at a utility platform of an aerial device, the system comprising:
an interlock detection assembly comprising:
an interlock sensor operable to detect an interlock state associated with an input device of the aerial device; and
a lanyard attachment assembly comprising:
at least one fixed element operable to receive the lanyard device;
a moveable element that is displaced when the lanyard device is attached to the at least one fixed element; and
an attachment sensor that determines a state of the lanyard attachment assembly responsive to detecting a position of the moveable element,
wherein the lanyard attachment assembly is in a first state when the lanyard device is not attached to the lanyard attachment assembly and the lanyard attachment assembly is in a second state when the lanyard device is attached to the lanyard attachment assembly.
29 . The system of claim 28 , wherein the interlock detection assembly comprises an interlock linkage with a magnetic component.
30 . The system of claim 29 , wherein the interlock sensor comprises a magnetically sensitive component operable to detect a presence of the magnetic component.
31 . The system of claim 28 , further comprising:
at least one hydraulic blocking valve operable to prevent one or more operations associated with the utility platform.
32 . The system of claim 31 , wherein the at least one hydraulic blocking valve comprises low-power hydraulic solenoid valve coupled to a hydraulic circuit of the utility platform such that the one or more operations are prevented by blocking hydraulic flow to at least a portion of the hydraulic circuit.
33 . The system of claim 28 , further comprising:
a visual indicator device operable to produce a visual alert indicative of the state of the lanyard attachment assembly.
34 . The system of claim 33 , wherein the visual indicator device comprises one or more light emitting diodes (LEDs) operable to be illuminated responsive to the state of the lanyard attachment assembly.
35 . The system of claim 28 , further comprising:
a force sensor operable to detecting an occupancy condition of the utility platform.
36 . A lanyard attachment assembly for detecting an attachment of a lanyard device at a utility platform of an aerial device, the lanyard attachment assembly comprising:
at least one fixed element comprising an opening operable to receive the lanyard device therein;
a spring-biased moveable element that is displaced when the lanyard device is attached to the at least one fixed element, the spring-biased moveable element comprising:
a compliant hinge component; and
a magnetic component; and
an attachment sensor that determines a state of the lanyard device responsive to detecting a position of the spring-biased moveable element by sensing the magnetic component,
wherein the lanyard attachment assembly is in a first state when the lanyard device is not attached to the lanyard attachment assembly and the lanyard attachment assembly is in a second state when the lanyard device is attached to the lanyard attachment assembly.
37 . The lanyard attachment assembly of claim 36 , wherein the spring-biased moveable element comprises a torsion spring disposed at the compliant hinge component that biases the spring-biased moveable element into a closed position.
38 . The lanyard attachment assembly of claim 36 , wherein the spring-biased moveable element comprises a spring steel material.
39 . The lanyard attachment assembly of claim 36 , further comprising:
a power source disposed at the utility platform operable to provide power to the attachment sensor.
40 . The lanyard attachment assembly of claim 39 , wherein the lanyard attachment assembly is electrically isolated from one or more electrically grounded components of the aerial device.
