Abstract

A monitoring system that allows for a handheld device to transmit information to a monitoring station indicative of an emergency situation within a facility. The handheld device is provided as a keyfob and transmits a wireless RF signal to transceivers variously positioned throughout the facility. Based on identifying which transceiver is in alert, personnel can determine the location of the emergency situation and track the movement of the keyfob as it is moved throughout the facility. Additionally, two-way communication can be established with via the system to provide a maximum amount of information to security personnel and first responders as well as allowing for specific instructions to be given to select personnel in the emergency area.

Claims

1. A monitoring system for monitoring an alert indicative of an emergency situation comprising:

at least one wireless transmitter transmitting a wireless signal indicating an emergency situation exists, said wireless signal further including information related to an individual to whom the wireless transmitter is assigned;

a plurality of transceivers located throughout a facility including a first transceiver that receives the wireless signal and transmits an alert signal to a security alert station indicating the identity of the transceiver that received the wireless signal and identifying the individual to whom the wireless transceiver is assigned;

wherein when said at least one wireless transmitter is moved away from the vicinity of said first transceiver and toward the vicinity of a second transceiver, the second transceiver transmits an alert signal to the security alert station indicating the identity of the second transceiver and identifying the individual to whom the wireless transmitter is assigned; and

wherein when both the first and second transceivers transmit alert signals, the system performs a signal strength comparison to determine which transceiver received a stronger wireless signal such that the monitoring system tracks the movement of the at least one wireless transmitter as it moves throughout the facility.

2. The monitoring system of claim 1 wherein each of said plurality of transceivers has a threshold signal level that must be reached prior to transmission of the alert signal.

3. The monitoring system of claim 1 wherein said at least one wireless transmitter comprises a keyfob.

4. The monitoring system of claim 1 wherein said wireless signal is an RF signal.

5. The monitoring system of claim 1 wherein when more than two transceivers receive a wireless signal that exceeds a threshold level of the respective transceivers, signal triangulation is used by the system to identify the location of said at least one wireless transmitter.

6. The monitoring system of claim 1 wherein the security alert station is located at the facility.

7. The monitoring system of claim 6 further comprising a visual display coupled to the monitoring system, said visual display presenting the layout of the facility and identifying the location of the transceiver in alert.

8. The monitoring system of claim 7 wherein said security alert station is coupled to a remote central monitoring station via a network connection.

9. The monitoring system of claim 1 further comprising an alert system to notify the facility of an alert status.

10. The monitoring system of claim 9 wherein said alert system provides for an automatic wireless alert to be sent to select personnel on site at the facility.

11. The monitoring system of claim 1 wherein said monitoring system allows a user to lock down the facility.

12. The monitoring system of claim 1 wherein said plurality of transceivers comprise wall-mounted transceivers.

13. The monitoring system of claim 12 wherein said wall-mounted transceivers provide two-way audio communication when activated.

14. The monitoring system of claim 1 further comprising a plurality of cameras positioned throughout the facility such that upon activation of one of said plurality of transceivers, one of said cameras will provide a video feed of the area adjacent to the activated transceiver.

15. The monitoring system of claim 14 wherein any of said plurality of cameras may be turned on from a remote location to provide a video feed of various parts of the facility.

16. The monitoring system of claim 1 wherein said wireless transmitter comprises a wireless transceiver.

17. The monitoring system of claim 16 wherein said wireless transceiver receives information related to the emergency situation.

18. The monitoring system of claim 1 wherein said plurality of transceivers are coupled to an AC power line and the alert signal is transmitted to the to the security alert station at least in part, via the AC power line.

19. A method of monitoring an alert indicative of an emergency situation comprising the steps of:

positioning a plurality of transceivers throughout a facility;

coupling the plurality of transceivers to a security alert station;

providing at least one wireless transmitter;

storing information related to an individual on the at least one wireless transmitter;

transmitting a wireless signal from the at least one wireless transmitter to at least one of the plurality of transceivers indicating an emergency situation exists, the wireless signal including information related to the individual to whom the wireless transmitter is assigned;

receiving the wireless signal at a first transceiver;

transmitting an alert signal from the first transceiver to a security alert station indicating the identity of the first transceiver and identifying the individual to whom the wireless transmitter is assigned;

moving the wireless transmitter away from the vicinity of the first transceiver and toward the vicinity of a second transceiver;

receiving the wireless signal at the second transceiver;

transmitting an alert signal from the second transceiver to the security alert station indicating the identity of the second transceiver and identifying the individual to whom the wireless transmitter is assigned;

performing a signal strength comparison of the wireless signals received at the first and second transceivers;

determining a location of the wireless transmitter based at least in part on the signal strength comparison such that the movement of the at least one wireless transmitter is tracked as it is moved throughout the facility.

20. The method of monitoring an alert of claim 19 wherein each of the plurality of transceivers has a threshold signal level that must be reached prior to transmission of the alert signal.

21. The method of monitoring an alert of claim 19 wherein the at least one wireless transmitter comprises a keyfob.

22. The method of monitoring an alert of claim 19 wherein the wireless signal is an RF signal.

23. The method of monitoring an alert of claim 19 wherein when more than two transceivers receive a wireless signal that exceeds a threshold level of the respective transceivers, signal triangulation is used to identify the location of the at least one wireless transmitter.

24. The method of monitoring an alert of claim 19 wherein the security alert station is located at the facility.

25. The method of monitoring an alert of claim 24 further comprising the step of displaying a visual representation of the facility layout and identifying the location of the transceiver in alert.

26. The method of monitoring an alert of claim 25 further comprising the step of coupling the security alert station to a remote central monitoring station via a network connection.

27. The method of monitoring an alert of claim 19 further comprising the step of notifying the facility of an alert status.

28. The method of monitoring an alert of claim 27 further comprising the step of sending an automatic wireless alert to select personnel on site at the facility.

29. The method of monitoring an alert of claim 19 further comprising the step of locking down the facility.

30. The method of monitoring an alert of claim 19 further comprising the step of mounting the plurality of transceivers to various walls in the facility.

31. The method of monitoring an alert of claim 30 further comprising the step of providing two-way audio communication between the wall-mounted transceiver and a central location.
