Abstract

Embodiments relate generally to systems and methods for establishing communication between an operator using a personal protection equipment (PPE) device and a central monitoring station, particularly in an emergency event. If the PPE device loses connection with a wireless network, and therefore with the central monitoring station, one or more method may be used to communicate information from the PPE device to the central monitoring station. One method may include sending a message to a predefined mobile number with location, operator, and alarm information. Another method may comprise establishing a Bluetooth connection with a secondary device, wherein the secondary device is connected to the wireless network, and sending data from the PPE device to the secondary device, wherein the secondary device forwards the data to the central monitoring station.

Claims

1-15. -15. (canceled)

16. A method of establishing communication between a personal protection equipment (PPE) device and a central monitoring station comprising:

sending, by the PPE device, raw data to a central monitoring station, wherein the PPE device and the central monitoring station communicate over a Wi-Fi network;

receiving and saving, by the PPE device, a current area name for the PPE device determined by the central monitoring station;

determining, by the PPE device, if the PPE device is in a Panic, Gas Alarms,or Man-down state;

when the PPE device is in one of these states, determining, by the PPE device, if the PPE device has lost connection with the Wi-Fi network;

when the connection with the Wi-Fi network has been lost, transmitting, by one of the PPE device and a secondary device, a Bluetooth beacon;

receiving the Bluetooth beacon by the device not transmitting the Bluetooth beacon;

establishing additional Bluetooth communication between the secondary device and the PPE device;

determining, by the PPE device, if the secondary device is connected to the central monitoring station via the Wi-Fi network;

when the secondary device is not connected to the central monitoring station, repeating the method from receiving the Bluetooth beacon by the device not transmitting the Bluetooth beacon until a secondary device is found that is connected to the central monitoring station;

when the secondary device is connected to the central monitoring station, forwarding alarm details by the PPE device to the secondary device, wherein the alarm details are forwarded by the secondary device to the central monitoring station, thereby establishing communication between the PPE device and the central monitoring station.

17. The method of claim 16, wherein the PPE device comprises a gas detector device.

18. The method of claim 16, further comprising reestablishing communication between the PPE device and the Wi-Fi network when the PPE device enters the range of a wireless router of the Wi-Fi network.

19. The method of claim 16, further comprising sending, by the PPE device, a message alert or voice alert to at least one preconfigured mobile number, wherein the alert comprises one or more of the most recent current area name received by the PPE device from the central monitoring station, operator information, and any other detected information.

20. A method of establishing communication between a personal protection equipment (PPE) device and a central monitoring station comprising:

sending data from one or more PPE device to a central monitoring station, wherein the PPE device and the central monitoring station communicate over a Wi-Fi network;

determining if the PPE device has lost connection with the Wi-Fi network;

when the connection with the Wi-Fi network has been lost, transmitting, by the PPE device, a Bluetooth beacon

receiving, by a secondary device, the Bluetooth beacon from the PPE device;

activating, by the secondary device, additional Bluetooth communication between the secondary device and the PPE device;

determining, by the PPE device, if the secondary device is connected to the central monitoring station via the Wi-Fi network;

when the secondary device is connected to the central monitoring station, forwarding data by the PPE device to the secondary device, wherein the data is forwarded by the secondary device to the central monitoring station, thereby establishing communication between the PPE device and the central monitoring station.

21. The method of claim 20, further comprising, when the secondary device is not connected to the central monitoring station, continuing to transmit the Bluetooth beacon by the PPE device until a secondary device is found that is connected to the central monitoring station.

22. The method of claim 20, further comprising, when the secondary device is not connected to the central monitoring station or when the Bluetooth beacon is not received by a secondary device, sending, by the PPE device, a message alert or voice alert to at least one preconfigured mobile number.

23. The method of claim 22, further comprising determining that the PPE device is in an a state.

24. The method of claim 23, further comprising including the alarm details in the message alert or voice alert sent to the preconfigured mobile number.

25. The method of claim 20, further comprising determining that the PPE device is in an alarm state, and forwarding the alarm details via the secondary device to the central monitoring station.

26. The method of claim 20, wherein the PPE device comprises a gas detector device.

27. The method of claim 20, further comprising reestablishing communication by the PPE device with the Wi-Fi network when the PPE device enters the range of a wireless router of the Wi-Fi network.

28. A communication system comprising:

at least one personal protection equipment (PPE) device configured to;

send data from the at least one PPE device to a central monitoring station, wherein the PPE device and the central monitoring station communicate over a Wi-Fi network;

determine if the PPE device has lost connection with the Wi-Fi network; and

when the connection with the Wi-Fi network has been lost, transmit a Bluetooth beacon; and

at least one secondary device configured to;

send data from the at least one secondary device to the central monitoring station, wherein the secondary device and the central monitoring station communicate over the Wi-Fi network;

receive the Bluetooth beacon transmitted y the PPE device;

establish Bluetooth communication between the secondary device and the PPE device;

receive data from the PPE device; and

forward the received data from the PPE device to the central monitoring station.

29. The communication system of claim 28, wherein the PPE device is further configured to determine that the PPE device in a Panic, Gas Alarm, or Man-down state.

30. The communication system of claim 28, wherein the PPE device is further configured to receive a current area name for the PPE device determined by the central monitoring station.

31. The communication system of claim 30, wherein the data forwarded by the secondary device from the PPE device to the central monitoring station comprises one or more of the most recent current area name received by the PPE device from the central monitoring station, operator information, and any other detected information.

32. The communication system of claim 30, wherein the PPE device is further configured to send a message alert or voice alert to at least one preconfigured mobile number, wherein the alert comprises one or more of the most recent current area name received by the PPE device from the central monitoring station, operator information, and any other detected information.

33. The communication system of claim 28, further comprising the central monitoring station configured to:

receive data from at least one PPE device over the Wi-Fi network;

determine the current area name for the PPE device based on the received data;

send the current area name to the PPE device.

34. The communication system of claim 33, wherein the central monitoring station is further configured to:

receive data from the secondary device over the Wi-Fi network; and

receive data from the PPE device forwarded by the secondary device over the Wi-Fi network.
