Abstract

A node monitoring system, including a plurality of nodes, each of the plurality of nodes registered and connected with a controller to simultaneously receive and return a short poll signal and a long poll signal; and a controller configured to: register an area as an operation zone having a boundary; simultaneously send and receive a short poll signal and a long poll signal to and from each of the plurality of nodes; command at least one of the plurality of nodes to power off in response to a failure to receive the short poll signal from the at least one of the plurality of nodes; alert others of the plurality of nodes that the at least one of the plurality of nodes is operating outside of a spatial boundary.

Claims (17)

1 . A work site monitoring system, comprising:

a plurality of work site nodes, each of the plurality of work site nodes registered and connected with a controller and configured to:

receive both a short poll signal and a long poll signal from the controller;

send a return short poll signal to the controller in response to receiving the short poll signal; and

send a return long poll signal to the controller in response to receiving the long poll signal; and

the controller configured to:

register an area as an operation zone having a boundary;

send the short poll signal and the long poll signal to and from each of the plurality of work site nodes;

receive the return short poll signal and the return long poll signal from each of the plurality of work site nodes;

in response to a failure to receive the return short poll signal from at least one of the plurality of work site nodes, command the at least one of the plurality of work site nodes to power off; and

in response to a failure to receive the return long poll signal from a work site node of the plurality of work site nodes, alert others of the plurality of work site nodes that the work site node is operating outside of a spatial boundary.

2 . The node monitoring system of claim 1 , wherein the operation zone having the boundary includes multiple operation zones each having a zone boundary.

3 . The node monitoring system of claim 1 , wherein the plurality of work site nodes includes a portable transmitter and receiver configured to be worn by a person.

4 . The node monitoring system of claim 1 , wherein the plurality of work site nodes includes a vehicle having a control module with a transmitter and a receiver.

5 . The node monitoring system of claim 4 , wherein the vehicle is operator controlled.

6 . The node monitoring system of claim 4 , wherein the vehicle is remote controlled.

7 . The node monitoring system of claim 4 , wherein the vehicle is an autonomous vehicle.
