Ladder having sensor and computing device for same
A ladder including sensors is provided. A remote computing device is also provided that communicates with the sensors to facilitate detection of various operating conditions. Methods for detection are also provided.
1. A non-transitory computer readable medium having instructions stored thereon which when executed by a processor cause the processor to:
wirelessly receive, by a remote computing device, sensor data from at least one sensor disposed on a ladder, the ladder being remote from the remote computing device;
cause a graphical user interface to be presented to a user on the remote computing device, wherein the graphical user interface comprises an alert portion;
determine, from the sensor data, whether a hazardous condition exists on the ladder; and
display an alert via the alert portion of the graphical user interface to the user when a hazardous condition exists on the ladder.
2. The non-transitory computer readable medium of claim 1 wherein the graphical user interface further comprises an alert dismiss portion and wherein the instructions further cause the processor to:
receive a selection of the alert dismiss portion by the user; and
deactivate displaying of the alert via the alert portion.
3. The non-transitory computer readable medium of claim 1 wherein the instructions further cause the processor to generate an audible alarm when the hazardous condition exists on the ladder.
4. The non-transitory computer readable medium of claim 1 wherein the instructions further cause the processor to initiate a distress call to an emergency services provider when the hazardous condition exists on the ladder.
5. The non-transitory computer readable medium of claim 1 wherein the hazardous condition comprises an unlocked condition of the spreader bar and wherein in order to determine whether the hazardous condition exists on the ladder, the instructions cause the processor to:
detect a presence of a user on the ladder from the sensor data; and
determine whether a spreader bar of the ladder is unlocked during the presence of the user on the ladder.
6. The non-transitory computer readable medium of claim 1 wherein the hazardous condition comprises an instability condition and wherein in order to determine whether the hazardous condition exists on the ladder, the instructions cause the processor to:
detect a presence of a user on the ladder from the sensor data; and
determine whether the ladder is unstable during the presence of the user on the ladder.
7. The non-transitory computer readable medium of claim 1 wherein the hazardous condition comprises a user present on an unauthorized step of the ladder and wherein in order to determine whether the hazardous condition exists on the ladder, the instructions cause the processor to:
detect a presence of a user on the ladder from the sensor data; and
determine whether the user is located on the unauthorized step.
8. The non-transitory computer readable medium of claim 1 wherein the hazardous condition comprises a user present on a brace section of the ladder.
9. The non-transitory computer readable medium of claim 1 wherein the at least one sensor comprises a Hall effect sensor.
10. The non-transitory computer readable medium of claim 9 wherein the Hall effect sensor is configured to detect deflection of a foot member of the ladder in response to load on the ladder being transmitted through the at least one sensor.
11. A non-transitory computer readable medium having instructions stored thereon which when executed by a processor cause the processor to:
wirelessly receive, by a remote computing device, sensor data from at least one sensor disposed on a ladder, the ladder being remote from the remote computing device;
cause a graphical user interface to be presented to a user on the remote computing device, wherein the graphical user interface comprises a reporting portion;
gather, from the sensor data, statistical information about the ladder;
store the statistical information as historical data;
receive a query for the historical data by the user; and
display the historical data to the user on the reporting portion based upon the query.
12. The non-transitory computer readable medium of claim 11 wherein the historical data comprises duration of usage of the ladder, past hazardous events, identification of users of the ladder, warranty information, and in service date.
13. The non-transitory computer readable medium of claim 11 wherein the at least one sensor comprises a Hall effect sensor.
14. The non-transitory computer readable medium of claim 13 wherein the Hall effect sensor is configured to detect deflection of a foot member of the ladder in response to load on the ladder being transmitted through the at least one sensor.
15. A non-transitory computer readable medium having instructions stored thereon which when executed by a processor cause the processor to:
wirelessly receive, by a remote computing device, sensor data from at least one sensor disposed on a ladder, the ladder being remote from the remote computing device;
cause a graphical user interface to be presented to a user on the remote computing device, wherein the graphical user interface comprises an acknowledgement portion;
detect a presence of a user on the ladder from the sensor data;
after detecting the presence of the user on the ladder, detect an absence of the user from the ladder from the sensor data;
after detecting the absence of the user from the ladder, request input from the user on the acknowledgement portion of the graphical user interface to confirm that the user has properly disembarked from the ladder; and
after passage of a predetermined time period without receiving input on the acknowledgement portion of the graphical user interface, generate an alert.
16. The non-transitory computer readable medium of claim 15 wherein in order to generate the alert, the instructions cause the processor to display an alert on an alert portion of the graphical user interface to the user.
17. The non-transitory computer readable medium of claim 15 wherein in order to generate the alert, the instructions cause the processor to initiate a distress call to an emergency services provider.
18. The non-transitory computer readable medium of claim 15 wherein the at least one sensor comprises a Hall effect sensor.
19. The non-transitory computer readable medium of claim 18 wherein the Hall effect sensor is configured to detect deflection of a foot member of the ladder in response to load on the ladder being transmitted through the at least one sensor.
