Wireless mesh network system for monitoring worksite events including detecting false events
First Claim
1. A communication system comprising:
- a plurality of communication nodes configured in a wireless mesh network at a worksite, the plurality of communication nodes including a plurality of router nodes; and
a plurality of sensor nodes in communication with one or more of the plurality of router nodes,wherein at least one sensor node communicates event data for at least one workplace event over the wireless mesh network to a management system by communicating with one or more of the plurality of router nodes which relay the event data to the management system, the at least one sensor node being worn by a monitored subject who experienced the at least one workplace event from a group comprising a fall event, a jump event, a slip and fall event, and a false event, the false event selected from a group comprising a sensor throw event and a sensor drop event, the sensor throw event being detected from the event data, based on, during a first time period, an acceleration of the at least one sensor node being greater than a first threshold amount, and the sensor drop event being detected from the event data, based on, during a second time period subsequent to the first time period, a rotation of the at least one sensor node having a peak angular velocity greater than a second threshold amount, andwherein at least one router node provides its location data to the management system for determining a location of the at least one workplace event.

Abstract
A system and associated interfaces are provided that permit the monitoring of workers within the workplace environment. In one aspect, a monitor having various sensing capabilities may be assigned to a monitored subject that records various parameters that are personal to the worker. For instance, it is appreciated that there may be sensor that can be attached to the monitored subject that is adapted to monitor certain parameters associated with the worker'"'"'s environment. For instance, a sensor assigned to the monitored subject may be capable of determining the location of the subject, along with motion, impacts, altitude, and other environmental parameters that could affect the health or other condition of the worker.
