US 9,792,796 B1 · Monitoring safety compliance based on RFID signals

Abstract

Where a safety requirement mandates contact with a grippable structural element such as a handle, a handrail, a handlebar or a steering wheel, compliance with the requirement may be determined using one or more manually activated RFID tags provided in designated locations on the grippable structural element. A level of compliance with the requirement during a given activity may be determined based at least in part on the number of RFID signals received from the manually activated RFID tags, which may be compared to a number of workers engaged in the given activity. Based on the level of compliance, relevant feedback in the form of electronic messages, signals or sounds may be identified and provided to one or more of the workers.

Dependent claims

A safety compliance system comprising:

a handrail associated with a set of stairs;
a plurality of manually activated radio-frequency identification (RFID) devices provided on the handrail;
an RFID reader;
a feedback device;
and
a computing device in communication with the RFID reader,
wherein the computing device is configured to at least:
determine, by at least one of the RFID reader or the computing device, a first number of a plurality of workers traveling on the set of stairs;
identify a second number of RFID signals received at the RFID reader from at least one of the plurality of manually activated RFID devices;
determine whether the second number equals the first number;
upon determining that the second number does not equal the first number,
identify a first feedback message for at least one of the plurality of workers based at least in part on the second number of RFID signals;
and
provide the first feedback message to the at least one of the plurality of workers by way of the feedback device.

A non-transitory computer-readable medium having computer-executable instructions stored thereon,

wherein the instructions, when executed, cause a computer system having at least one computer processor to perform a method comprising:
determining that at least a first worker and a second worker are contacting at least a portion of a grippable element;
identifying a first plurality of radio-frequency identification (RFD)) signals received from manually activated RFID tags disposed on the grippable element, wherein each of the first plurality of RFID signals is transmitted upon contact with at least the portion of the grippable element by one of the first worker or the second worker;
defining a first pattern of contact based at least in part on the first plurality of RFID signals;
generating at least a first vector based at least in part on the first pattern of contact;
determining first information regarding the contact with at least the portion of the grippable element by the one of the first worker or the second worker;
providing at least the first vector and at least some of the first information regarding the contact with at least the portion of the grippable element to a machine learning system as inputs;
receiving at least one output from the machine learning system;
and
identifying the first worker based at least in part on the at least one output.
