Safety ground wire monitoring and alarm systems

A system for monitoring the integrity of a plurality of ground conductors, the system comprising:

• a plurality of sensor nodes, wherein each sensor node is associated with a different one of the ground conductors and includes a wireless transmitter configured to transmit wireless signals;
• a gateway configured to receive wireless signals from the wireless transmitters and transmit signals including information regarding the plurality of sensor nodes;
• and
• a user interface platform configured to access and simultaneously display the information regarding at least two of the plurality of sensor nodes, wherein
• the user interface platform is configured to simultaneously display at least two cells,
• the information regarding each one of said at least two of the plurality of sensor nodes is displayed in a different one of said at least two cells,
• the user interface platform is configured to display a status of each one of said at least two of the plurality of sensor nodes,
• the status is selected from a plurality of statuses,
• each one of said plurality of statuses is indicated by a different cell appearance, and
• said plurality of statuses include
• an “idle” condition in which the sensor node has not yet been associated with one of said plurality of ground conductors and/or has not yet been activated,
• an “alert” condition in which the sensor node detects possible compromise of the integrity of the associated ground conductor,
• a “warning” condition in which the sensor node is not operating normally, but has not detected possible compromise of the integrity of the associated ground conductor, and
• a “normal operation” condition in which the sensor node is operating normally and has not detected possible compromise of the integrity of the associated ground conductor.
