Abstract

A sensor is coupled to a device positioned within an enclosure and is configured to determine the status of the device or its surrounding environment. The sensor transmits the information to a central computer and/or a local indicator. Once the information is received at the central computer, the information is processed for the operators and maintainers to interpret. Based on the information received, the operators and maintainers may implement procedures to maintain the device or its surrounding environment under observation. In certain embodiments, the central computer provides instructions to a second device within or adjacent to the enclosure to implement corrective actions. In some embodiments, the sensor is coupled to a microcontroller which performs analysis received from the sensor and provides instructions to the second device to implement corrective actions.

Claims

1. A monitoring system for an electrical component, comprising:

one or more sensors for monitoring a status of an electrical component or a surrounding environment of the electrical component, the sensor generating a first signal indicating the status;

a transceiver communicably coupled to the sensor, wherein the transceiver receives the first signal from the sensor; and

a central computer located at a remote location from the electrical component, the central computer receives the first signal from the transceiver, the central computer processes the first signal and sends a corrective action signal to the transceiver to instruct a device to change the status of the electrical component or the surrounding environment of the electrical component when the status is determined to be improper,

wherein the electrical component is enclosed within a sealed enclosure.

2. The monitoring system of claim 1, wherein the sensor and the transceiver are enclosed within the enclosure.

3. The monitoring system of claim 1, further comprising a microcontroller, wherein the transceiver is communicably coupled to the sensor through the microcontroller, and wherein the microcontroller allows the transceiver to send the first signal to the central computer only when the status of the electrical component or the surrounding environment of the electrical component is determined to be improper.

4. The monitoring system of claim 3, wherein the microcontroller is enclosed within the enclosure.

5. The monitoring system of claim 1, wherein the central computer wirelessly receives the first signal from the transceiver.

6. The monitoring system of claim 1, further comprising a local indicator located outside the enclosure, the local indicator communicably coupled to the sensor, the local indicator providing a status of the electrical component or the surrounding environment of the electrical component to an observer without the observer having to open the enclosure.

8. The monitoring system of claim 6, wherein the local indicator comprises one or more light indicators to indicate one or more different statuses of the electrical component or the surrounding environment of the electrical component.

9. The monitoring system of claim 6, wherein the one or more different statuses comprise a proper operating status, a warning operating status, and a critical operational status.
