Abstract
Described are the method(s) and device(s) that integrate sensors, algorithms, software applications, wireless technologies, data protocols, communication networks, data storage, energy harvesting, edge computing, cloud computing, machine learning, and artificial intelligence techniques to monitor aboveground and underground cable(s) used in industrial, mining, power transmission and distribution, server farm and commercial areas; to prevent loss of connectivity, hazards and risks from cable(s) that connect fixed and non-fixed plant assets and equipment such as pump drives, barges, shovels, dozers, trucks and related equipment.
In this invention, we additionally propose a distributed device network, communication backbone and software applications that monitor electrical and mechanical health of the cable(s) to improve predictive and preventive maintenance strategies for cable(s) in aboveground and underground industrial areas.
In this invention, we additionally propose a distributed device network, communication backbone and software applications that monitor electrical and mechanical health of the cable(s) to improve predictive and preventive maintenance strategies for cable(s) in aboveground and underground industrial areas.
Description
SUMMARY:
In this invention, we are proposing cable(s) mechanical and electrical health monitoring solution whose orchestration is shown in Figure.1 . In a typical aboveground, underground and indoor industrial application, a substation power source 100 feeds the cable(s) 101 that power fixed and mobile industrial equipment such as electric shovel loads or a pump drive 103. The cable(s) extend from few feet to thousands of meters depending upon the location of the source 100 and the load 103.
Several device(s) 102 are installed on or attached to the cable 101 or cable(s) accessories such as cable stands. These devices measure the energized and de-energized state and mechanical health metrics such as bend radius, vibration, shock, pulling tension of the cable(s) using either invasive or non-invasive sensing mechanisms. Different types of measurements associated with cable(s) 101 health are discussed in the claims.
The devices 102 can be installed at any location along the length of the cable(s) ¨ at the source, along the cable contour, and at the load.
The devices 102 transmit the electrical and mechanical measurements to a nearest gateway 104, 106 over a wireless or wired network. The implementation supports the use of a both cloud information infrastructure 105 and/or an on-premise 105, 107 enterprise networks for data exchange and control. The energized and de-energized state of the cable(s) along with the mechanical health metrics can be accessed by a field operator 109 and by a mobile mining equipment operator 110. The application layer 108 aggregates all the sensor information collected from devices 102 from different cable(s) 101 strings and runs a sophisticated machine learning algorithm to assess the electrical and mechanical health of the cable(s).
BRIEF DESCRIPTION OF THE DRAWINGS:
Figure.1 Illustrates the orchestration of a distributed sensor network, wireless and wired network connectivity, application software, cloud, on premise/enterprise data storage, and information technology is deployed to monitor mechanical and electric health of the data and power cable(s) in aboveground, underground and indoor industrial areas.

A variety of invasive and non-invasive sensing principles such as optical, electromagnetic, magnetic field sensing, electromechanical, electric field sensing, mechanical sensing, electrochemical are used to monitor the energized state of the cable(s). The energized state sensed by the device will be transmitted over a wired or wireless network for remote monitoring and alerting.
2. The device described in claim 1 may also have a local visual or audio indication to alert the field personnel to the energized and de-energized state of the cable(s).
3. The energized state of the cable(s) measured by the device described in claim 1 may be treated as a primary indication and the cable(s) status is corroborated with the cable string check procedure ensuring visual verification of cable number(s) for validation.
4. The device described in claim 1 may be placed at any location along the cable(s); for example, at the substation close to the power source or at the load side such as a shovel for a power and data transmission cable(s).
5. If the insulation on the cable(s) prohibits the device described in claim 1 from accurately measuring the energized and de-energized state of the cable(s), then additional sensor(s) are proposed to improve the accuracy of the device described in claim 1 to identify the energized /de-energized state of the cable(s) by monitoring the relay status associated with the cable(s) themselves.
6. A secondary device with motion sensor(s) may be placed on or attached to the cable(s) close to the load side of mobile mining equipment like a shovel. The motion variables such as vibration or acceleration or shock picked up by this second device provide additional confirmation to the primary device in claim 1 to cross validate energized and de-energized state of the cable(s).
7. Multiple number of devices described in claim 1 are placed on or attached to the cable along its length to measure the contour of the cable(s). The contour is obtained by aggregating the geo-location of the devices along the cable length using GPS/GNSS
coordinates of the device in aboveground industrial areas. If the device described in claim 1 are attached to cable(s) in underground or indoor industrial areas, then the devices can form a mesh network and variables such as radio/wireless signal strength of the devices are used to infer indoor location of the devices placed along the cable(s) and hence able to obtain the contour of cable(s).
