Abstract

This disclosure relates to method and system for determining probability of an alarm generated by an alarm system. The method may include receiving sensor data and maintenance data. The sensor data may include one or more environmental parameters and one or more trigger parameters, and the alarm is generated based on the one or more trigger parameters. The method may further include generating one or more input vectors based on the sensor data and the maintenance data, and determining a spuriosity index of the alarm based on the one or more input vectors using a machine learning model. The machine learning model may be created using historical sensor data and historical maintenance data, and the spuriosity index is indicative of the probability of the alarm.

First claim

What is claimed is:

1. A method of determining probability of an alarm generated by an alarm system, the method comprising:
receiving, by an alarm validation device, sensor data and maintenance data, wherein the sensor data comprises one or more environmental parameters and one or more trigger parameters, and wherein the alarm is generated based on the one or more trigger parameters;
generating, by the alarm validation device, one or more input vectors based on the sensor data and the maintenance data; and
determining, by the alarm validation device, a spuriosity index of the alarm based on the one or more input vectors using a machine learning model, wherein the machine learning model is created using historical sensor data and historical maintenance data, and wherein the spuriosity index is indicative of the probability of the alarm.

2. The method of claim 1 , wherein the one or more environmental parameters comprise one or more real-time ambient parameters with respect to each of one or more sensors configured for acquiring each of the one or more trigger parameters, and wherein the one or more real-time ambient parameters comprise an ambient temperature, an ambient humidity, an ambient pressure, or an ambient particulate matter.

3. The method of claim 1 , wherein the one or more trigger parameters comprise one or more hazardous substances, or one or more hazardous conditions, wherein the one or more hazardous substances comprise an inflammable gas, or a poisonous gas, and wherein the one or more hazardous conditions comprise a build-up of the one or more hazardous substances.

4. The method of claim 1 , wherein the maintenance data comprises specifications, an installation date, a calibration date, or one or more previous servicing dates of one or more sensors configured for acquiring the sensor data, or power supply data for a monitored system configured to generate the one or more trigger parameters.

5. The method of claim 1 , further comprising:
providing, by the alarm validation device, the alarm, the sensor data, the maintenance data, and the spuriosity index to a user via a dashboard.

6. The method of claim 5 further comprising:
receiving, by the alarm validation device, an assessment from the user on the probability of the alarm.

7. The method of claim 6 , further comprising:
updating, by the alarm validation device, a historical data repository with the sensor data, the maintenance data, the alarm, the spuriosity index, and the assessment; and
retuning, by the alarm validation device, the machine learning model based on updated historical data from the historical data repository.

8. The method of claim 7 , wherein a frequency of retuning is based on the one or more environmental parameters and one or more operating conditions.

9. The method of claim 6 , further comprising:
adjusting one or more conditions for generation of the alarm based on the spuriosity index and the assessment.

10. A system for determining probability of an alarm generated by an alarm system, the system comprising:
an alarm validation device comprising at least one processor and a non-transitory computer readable medium storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
receiving sensor data and maintenance data, wherein the sensor data comprises one or more environmental parameters and one or more trigger parameters, and wherein the alarm is generated based on the one or more trigger parameters;
generating one or more input vectors based on the sensor data and the maintenance data; and
determining a spuriosity index of the alarm based on the one or more input vectors using a machine learning model, wherein the machine learning model is created using historical sensor data and historical maintenance data, and wherein the spuriosity index is indicative of the probability of the alarm.

11. The system of claim 10 ,
wherein the one or more environmental parameters comprise one or more real-time ambient parameters with respect to each of one or more sensors configured for acquiring each of the one or more trigger parameters, and wherein the one or more real-time ambient parameters comprise an ambient temperature, an ambient humidity, an ambient pressure, or an ambient particulate matter, or
wherein the one or more trigger parameters comprise one or more hazardous substances, or one or more hazardous conditions, wherein the one or more hazardous substances comprise an inflammable gas, or a poisonous gas, and wherein the one or more hazardous conditions comprise a build-up of the one or more hazardous substances, or
wherein the maintenance data comprises specifications, an installation date, a calibration date, or one or more previous servicing dates of one or more sensors configured for acquiring the sensor data, or power supply data for a monitored system configured to generate the one or more trigger parameters.

12. The system of claim 10 , wherein the operations further comprise:
providing the alarm, the sensor data, the maintenance data, and the spuriosity index to a user via a dashboard; and
receiving an assessment from the user on the probability of the alarm.

13. The system of claim 12 , wherein the operations further comprise:
updating a historical data repository with the sensor data, the maintenance data, the alarm, the spuriosity index, and the assessment; and
retuning the machine learning model based on updated historical data from the historical data repository, wherein a frequency of retuning is based on the one or more environmental parameters and one or more operating conditions.

14. The system of claim 12 , wherein the operations further comprise:
adjusting one or more conditions for generation of the alarm based on the spuriosity index and the assessment.

15. A non-transitory computer readable medium storing computer-executable instructions for:
receiving sensor data and maintenance data, wherein the sensor data comprises one or more environmental parameters and one or more trigger parameters, and wherein the alarm is generated based on the one or more trigger parameters;
generating one or more input vectors based on the sensor data and the maintenance data; and
determining a spuriosity index of the alarm based on the one or more input vectors using a machine learning model, wherein the machine learning model is created using historical sensor data and historical maintenance data, and wherein the spuriosity index is indicative of the probability of the alarm.

16. The non-transitory computer readable medium of the claim 15 ,
wherein the one or more environmental parameters comprise one or more real-time ambient parameters with respect to each of one or more sensors configured for acquiring each of the one or more trigger parameters, and wherein the one or more real-time ambient parameters comprise an ambient temperature, an ambient humidity, an ambient pressure, or an ambient particulate matter, or
