Abstract

Apparatus and associated methods relate to a smart hook, a safety harness module, and associated electronic components that detect a safety state of a user by monitoring various parameters at the smart hook and safety harness module and determining whether the user is using proper safety protocol at extreme heights and/or whether the user has experienced a height-related accident. In an illustrative example, the user may don a safety harness that may include a module that contains sensors that monitor an acceleration/velocity/position of the user and/or ambient air pressure around the user. The module may receive wireless signals from at least one rebar hook having sensors that monitor the acceleration/velocity/position and gate position of the rebar hooks. A controller included with the safety harness module may use these sensors to advantageously determine the safety state of the user and generate alert/warning signals.

Dependent claims

A safety monitoring apparatus comprising:

a monitoring module configured to couple to a safety harness, the monitoring module comprising:
a main acceleration sensor;
an air pressure sensor;
a controller coupled to the main acceleration sensor and configured to receive sensor readings from the main acceleration sensor, the controller also coupled to the air pressure sensor and configured to receive sensor readings from the air pressure sensor;
a receiver coupled to the controller;
a first rebar hook configured to couple to a distal end of a lanyard, the lanyard being configured to couple at a proximal end to the safety harness, the first rebar hook comprising:
a first acceleration sensor;
a first hook sensor configured to detect an open-closed state of the first rebar hook, the first hook sensor comprising a magnetic field sensor;
a first rebar hook transmitter coupled to the first acceleration sensor and first hook sensor, the first rebar hook transmitter being configured to transmit sensor readings from the first acceleration sensor and the first hook sensor to the receiver of the monitoring module;
and
a first magnetic field generator that cooperates with the first hook sensor to detect the open-closed state of the first rebar hook, the monitoring module further comprising:
a main transmitter coupled to the controller and configured to transmit signals to a remote computing device.
