Abstract

An electric appliance health monitoring device, and a method for detecting and reporting appliance failure or pending failure are provided. The device includes voltage conversion and power management with a rechargeable battery capability to provide operating power for device function. The device provides power to an electrical appliance, monitoring the appliance voltage and current usage with a current sensor to detect power failure or appliance anomalous operation. The device includes a wireless transceiver to communicate device status and report appliance anomalous operation. The method includes statistical analysis with thresholding and predictive analytics for determining failure or pending failure of an appliance. This method also provides for remote notification and control of the anomaly detection process using long-range radio and data communications methods.

Dependent claims

An electronic device comprising:

(a) a voltage converter configured to accept power from an external voltage source, and convert the voltage for device operation;
(b) a rechargeable battery configured to provide voltage for device operation upon failure of the external voltage source;
(c) a power manager configured to provide continuous voltage for device operation using voltage from at least one of the voltage converter and the rechargeable battery, and to manage a recharge operation of the rechargeable battery;
(d) a current sensor configured to measure electrical current drawn by an external appliance, and to provide a sensor voltage output based upon an external appliance load current;
(e) a wireless transceiver with associated antenna configured to enable the device to communicate device operational and sensor data, and to receive device configuration settings from an external management system utilizing wireless communication;
and
(f) a controller configured to
monitor device voltage inputs of the voltage converter,
monitor rechargeable battery status and operation controlled by the power manager,
monitor sensor voltage output from the current sensor,
perform temporal statistical analysis processes to ascertain anomalous operation of the external appliance, and
report, via the wireless transceiver, anomalous operation of the external appliance, anomalous power input from the external voltage source, and operational status of the electronic device.

A system for detecting anomalous operation of an electrical appliance, the system comprising:

(a) a current measurement module to perform sampled measurements of operating current of an appliance to include event data elements of:
(i) detection of change of appliance current value denoting an appliance start event time;
(ii) detection of change of appliance current value denoting an appliance stop event time;
(iii) calculating a peak current for a run event defined by the appliance start event time and the appliance stop event time;
(iv) calculating a mean current for the run event;
(v) measuring a run duration of the run event;
and
(vi) measuring an idle duration between run events;
and
(b) a data storage configured to store measured sampled voltage and event data elements;
(c) a temporal statistical comparative analysis module configured to create a first long-duration histogram of historical run event data previously measured from the electrical appliance to include a minimum amount of event data sets, and configured to create a second short-duration histogram of historical run event data previously measured from the electrical appliance to include at least one run event data set including a most recent sample;
(d) a thresholding module configured to compare and determine if at least one of the data bin indexes of the second short-duration histogram exceeds a calculated statistical threshold thus detecting anomalous appliance operation;
(e) a long-range reporting module configured to enable data communication between the current measurement module and a remote computer system;
and
(f) a communication module configured to communicate detected anomalous operational events, anomalous voltage measurements, and anomalous current measurements to the remote computer system.
