Abstract

A method of operating a push-to-anything (PTX) platform includes receiving, by a data analytics engine (DAE) of the PTX platform, a first input signal from a first input source; calculating, by the DAE, a risk indicator using the first input signal, the risk indicator indicating a level of a security threat; detecting a risk event, by the DAE, when the risk indicator is above a first pre-determined risk threshold, the first pre-determined risk threshold corresponding to a pre-determined level of security threat above which an emergency response protocol is initiated; generating, by the DAE, a group list in response to detecting the risk event, where the group list comprises one or more client devices of the PTX platform; sending, by the DAE, the group list to a PTX server of the PTX platform; and notifying, by the PTX server, the one or more client devices in the group list of the risk event.

Claims

1. A method of operating a push-to-anything (PTX) platform, the method comprising:

receiving, by a data analytics engine (DAE) of the PTX platform, a first input signal from a first input source;

calculating, by the DAE, a risk indicator using the first input signal, the risk indicator indicating a level of a security threat, wherein the DAE calculates the risk indicator using the first input signal and a historical record of the first input signal;

detecting a risk event, by the DAE, when the risk indicator is above a first pre-determined risk threshold, the first pre-determined risk threshold corresponding to a pre-determined level of security threat above which an emergency response protocol is initiated;

generating, by the DAE, a group list in response to detecting the risk event, wherein the group list comprises one or more client devices of the PTX platform;

sending, by the DAE, the group list to a PTX server of the PTX platform; and

notifying, by the PTX server, the one or more client devices in the group list of the risk event.

2. The method of claim 1, wherein the group list is dynamically generated based on one or more attributes of the input signal.

3. The method of claim 2, wherein the one or more attributes of the input signal comprise an incident type of the risk event, a location of the risk event, or time of the risk event.

4. The method of claim 3, wherein the group list is dynamically generated based on additional information that comprises a shift schedule of emergency response personnel and available resources for emergency response.

5. The method of claim 1, further comprising:

receiving, by the DAE, a second input signal from a second input source, wherein the DAE calculates the risk indicator using the first input signal and the second input signal.

6. The method of claim 5, wherein the first input source and the second input source have different sensors.

7. The method of claim 1, wherein the first input signal is a streaming data within a set time period, wherein the DAE calculates the risk indicator by continuously analyzing the streaming data within the set time period.

8. The method of claim 1, wherein the first input signal comprises a plurality of data points that are sampled at a plurality of discrete time slots, wherein the DAE updates the calculated risk indicator in response to an incoming data sample of the first input signal.

9. The method of claim 1, wherein the notifying comprises sending text, data, audio message, or video message to the one or more client devices in the group list.

10. The method of claim 1, wherein the first input signal is a sensor signal of an air tank, and the risk indicator indicates the likelihood that a remaining amount of oxygen in the air tank is below a pre-determined amount of oxygen in the air tank.

11. The method of claim 1, wherein the first input signal is a sensor signal of a temperature sensor, and the risk indicator indicates the likelihood that a fire breaks out.

12. The method of claim 11, wherein the risk indicator is calculated using a history data base of the ambient temperature of the temperature sensor, the time when the sensor signal was sampled, and the season when the sensor signal was sampled.

13. The method of claim 1, further comprising:

deploying, by the DAE, a drone to a location indicated by the first input signal;

receiving, by the DAE, sensor data sent by the drone; and

relaying, by the DAE, the sensor data sent by the drone to the one or more client devices in the group list.

14. A method of operating a push-to-talk (PTT) system, the PTT system comprising a data analytics engine (DAE), the method comprising:

receiving, by the DAE, a first signal from a first sensor;

providing, by the DAE, analytics of the first signal based on the received first signal and a historical data of the first signal, wherein the analytics of the first signal comprises a first predicted risk indicator, wherein the first predicted risk indicator indicates a level of a security threat at a future time;

detecting, by the DAE, a potential risk event by comparing the first predicted risk indicator and a first pre-determined risk threshold, wherein the first pre-determined risk threshold corresponds to a pre-determine level of security threat above which risk management sources are deployed; and

notifying, by the PTT system, one or more client devices of the potential risk event, wherein the one or more client devices are in a group list of the PTT system.

15. The method of claim 14 further comprising:

receiving, by the DAE, a second signal from a second sensor, wherein the first sensor and the second sensor are different types of sensors; and

calculating, by the DAE, a second predicted risk indicator, wherein the second predicted risk indicator indicates a level of the security threat at the future time, wherein the DAE detects the potential risk event using the first predicted risk indicator and the second predicted risk indicator.

16. The method of claim 15, further comprising, before notifying the one or more client devices:

dynamically generating, by the DAE, the group list based on at least an incident type of the potential risk event and a location of the potential risk event.

17. A push-to-anything (PTX) system comprising:

a data analytics engine (DAE), wherein the DAE is configured to;

receive a first signal from a first source;

calculate a first risk indicator using the first signal, the first risk indicator indicating a level of a first security threat;

detect a risk event when the first risk indicator is above a first pre-determined risk threshold, the first pre-determined risk threshold corresponding to a pre-determine level of the first security threat above which an emergency response protocol is initiated;

generate a first group list in response to detecting the risk event, wherein the first group list comprises one or more client devices of the PTX system;

send the first group list to a PTX server of the PTX system, wherein the PTX server is configured to notify the one or more client devices in the first group list of the risk event;

receive a second signal from a second source;

calculate a second risk indicator using the second signal and a history record of the second signal, the second risk indicator indicating a predicted level of a second security threat at a future time;

identify a potential risk event when the second risk indicator is above a second pre-determined risk threshold;

generate a second group list comprising one or more client devices of the PTX system; and

send the second group list to a push-to-talk (PTT) server of the PTX system, wherein the PTT server is configured to notify the one or more client devices in the second group list of the potential risk event.

18. The PTX system of claim 17, wherein the DAE is configured to:

update an algorithm of the DAE used for calculating the second risk indicator, based on whether or not the potential risk event actually happened; and

use the updated algorithm to calculate a third risk indicator indicating a predicated level of the second security threat at another future time.
