Abstract

A system for environmental monitoring and user health is provided. The system includes a multi-sensor deployed in a local space of a building to sense multiple characteristics of the local space and a building management system receptive of signals from the multi-sensor, the signals being indicative of the multiple characteristics sensed by the multi-sensor. The building management system is configured to determine whether the local space is exhibiting an unhealthy condition based on the signals and to prevent user access, which would be otherwise authorized, to the local space exhibiting the unhealthy condition while the unhealthy condition persists.

Claims (49)

1 . A system for environmental monitoring and user health, the system comprising:

a multi-sensor deployed in a local space of a building to sense multiple characteristics of the local space; and

a building management system receptive of signals from the multi-sensor, the signals being indicative of the multiple characteristics sensed by the multi-sensor,

the building management system being configured to:

determine whether the local space is exhibiting an unhealthy condition based on the signals; and

prevent user access, which would be otherwise authorized by credentials associated with a key card of a user, to the local space exhibiting the unhealthy condition while the unhealthy condition persists by disabling the key card of the user from unlocking a door lock of the local space while the unhealthy condition persists,

wherein the building comprises a cruise ship and the local space comprises a stateroom or a portion of a stateroom of the user; and

wherein the building management system is further configured to control fire/water doors of the cruise ship, direct users to lifeboats and track user locations on the cruise ship.

2 . The system according to claim 1 , wherein the multiple characteristics of the local space sensed by the multi-sensor comprise at least humidity, temperature and noise levels of the local space.

3 . The system according to claim 1 , wherein the multi-sensor is communicative with the building management system via wired or wireless communications and the building management system comprises:

a central server;

a gateway communicatively interposed between the central server and one or more of the multi-sensor; and

a cloud network communicatively interposed between the gateway and the central server.

4 . The system according to claim 1 , wherein the building management system is further configured to notify the user as to the unhealthy condition and a status of user access.

5 . The system of claim 1 , wherein the building management system prevents user access by engaging a dead-bolt lock that remains engaged until the unhealthy condition returns to normal.

6 . The system of claim 1 , wherein the building management system communicates health status information to users via a mobile credentialing system specific to cruise ship operations.

7 . A system for environmental monitoring and user health, the system comprising:

multi-sensors, each of which is deployed in local spaces of a building to sense multiple characteristics of each local space; and

a building management system receptive of signals from each of the multi-sensors, the signals being indicative of the multiple characteristics sensed by each of the multi-sensors,

the building management system being configured to determine whether one or more local spaces are exhibiting an unhealthy condition based on the signals and to prevent user access, which would be otherwise authorized by credentials associated with a key card of a user, to the one or more local spaces exhibiting the unhealthy condition while the unhealthy condition persists by disabling the key card of the user from unlocking a door lock of the local space while the unhealthy condition persists,

wherein the building comprises a cruise ship and one or more of the local spaces comprises a stateroom or a portion of a stateroom of the user; and

wherein the building management system is further configured to control fire/water doors on the cruise ship, direct users to lifeboats and track user locations on the cruise ship.

8 . The system according to claim 7 , wherein the multiple characteristics of the local spaces sensed by each of the multi-sensors comprise at least humidity, temperature and noise levels of the local spaces.

9 . The system according to claim 8 , wherein each of the multi-sensors is communicative with the building management system via wired or wireless communications and the building management system comprises:

a central server;

a gateway communicatively interposed between the central server and one or more of the multi-sensors; and

a cloud network communicatively interposed between the gateway and the central server.

10 . The system according to claim 7 , wherein the building management system is further configured to notify the user as to the unhealthy condition and a status of user access.

11 . The system of claim 7 , wherein the building management system prevents user access by engaging a dead-bolt lock that remains engaged until the unhealthy condition returns to normal.

12 . A method for environmental monitoring and user health, the method comprising:

deploying multi-sensors to sense multiple characteristics of each local space of a building;

generating signals indicative of the multiple characteristics sensed by each of the multi-sensors;

receiving the signals at a building management system;

determining, at the building management system, whether one or more local spaces are exhibiting an unhealthy condition based on the signals; and

preventing, by the building management system, user access that would be otherwise authorized by credentials associated with a key card of a user to the one or more local spaces exhibiting the unhealthy condition while the unhealthy condition persists by disabling the key card of the user from unlocking a door lock of the local space while the unhealthy condition persists;

wherein the building comprises a cruise ship and one or more of the local spaces comprises a stateroom or a portion a stateroom or the user; and

the method further comprising:

controlling, by the building management system, fire/water doors of the cruise ship;

directing, by the building management system, users to lifeboats; and

tracking, by the building management system, user locations on the cruise ship.

13 . The method according to claim 12 , wherein:

the multiple characteristics of the local spaces sensed by each of the multi-sensors comprise at least humidity, temperature and noise levels of the local spaces.

14 . The method according to claim 12 , wherein each of the multi-sensors is communicative with the building management system via wired or wireless communications and the building management system comprises:

a central server;

a gateway communicatively interposed between the central server and one or more of the multi-sensors; and

a cloud network communicatively interposed between the gateway and the central server.

15 . The method according to claim 12 , further comprising notifying, by the building management system, the user as to the unhealthy condition and a status of user access.

16 . The method of claim 12 , further comprising preventing, via the building management system, user access by engaging a dead-bolt lock that remains engaged until the unhealthy condition returns to normal.

17 . The method of claim 12 , further comprising communicating, via the building management system, health status information to users via a mobile credentialing system specific to cruise ship operations.
