Abstract

The present disclosure describes computer-implemented methods, computer program products, and computer systems, for role-based plants unattended premises occupancy monitoring, mapping, and events logging. One computer implemented method includes unlocking a mechanical door controllable by a computing device upon successfully validating login information input by an occupant, performing an occupancy footprint mapping (OFM) by periodically calculating the occupant'"'"'s location using a triangulation process, determining an identity of the occupant based a received RFID signal, identifying a job role for the occupant based on the occupant'"'"'s identity, identifying a normal OFM associated with the occupant'"'"'s job role, calculating a deviation between the OFM and the normal OFM, sending a security event including the OFM to a Syslog server and an object linking, and sending an embedding for process control alarm to a human machine interface if the deviation exceeds a predetermined deviation tolerance threshold.

Claims

1. A computer-implemented method, comprising:

unlocking a mechanical door controllable by a computing device upon successfully validating login information input by an occupant;

performing an occupancy footprint mapping (OFM) by periodically calculating the occupant'"'"'s location using a triangulation process based on signals sensed by one or more occupancy sensors, wherein the OFM indicates the occupant'"'"'s movements over time;

determining an identity of the occupant based a received RFID signal;

identifying a job role for the occupant based on the occupant'"'"'s identity;

identifying a normal OFM associated with the occupant'"'"'s job role stored in an authentication server, wherein the normal OFM indicates a normal behavior occupancy map for the occupant'"'"'s job role;

calculating a deviation between the OFM and the normal OFM;

sending a security event including the OFM to a Syslog server; and

sending an object linking and embedding for process control (OPC) alarm to a human machine interface if the deviation exceeds a predetermined deviation tolerance threshold.

2. The computer-implemented method of claim 1, wherein the login information is input through a keypad attached to the mechanical door.

3. The computer-implemented method of claim 1, wherein the login information is input through a biometric sensor attached to the mechanical door, wherein the biometric sensor is at least one of a voiceprint sensor, fingerprint sensor, or an iris scanner.

4. The computer-implemented method of claim 1, wherein the computing device that controls the mechanical door runs a security configuration software that resolves a logic of securing a locking mechanism of the mechanical door.

5. The computer-implemented method of claim 1, wherein the authentication server is a remote authentication dial-in user service server, a terminal access controller access-control system server or an active directory server.

6. The computer-implemented method of claim 1, wherein the computing device that controls the mechanical door runs a process control software that performs at least one of the triangulation process, sending the security event to the syslog server, sending the OPC alarm to a human machine interface (HMI), or providing 802.1x protocol support.

7. The computer-implemented method of claim 1, wherein the occupancy sensor is an ultrasound proximity sensor, a thermo-image sensor, or a piezoelectric sensor.

8. The computer-implemented method of claim 1, wherein the mechanical door includes a lock latch actuated by air pressure or induced pressure.

9. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

unlocking a mechanical door controllable by a computing device upon successfully validating login information input by an occupant;

performing an occupancy footprint mapping (OFM) by periodically calculating the occupant'"'"'s location using a triangulation process based on signals sensed by one or more occupancy sensors, wherein the OFM indicates the occupant'"'"'s movements over time;

determining an identity of the occupant based a received RFID signal;

identifying a job role for the occupant based on the occupant'"'"'s identity;

identifying a normal OFM associated with the occupant'"'"'s job role stored in an authentication server, wherein the normal OFM indicates a normal behavior occupancy map for the occupant'"'"'s job role;

calculating a deviation between the OFM and the normal OFM;

sending a security event including the OFM to a Syslog server; and

sending an object linking and embedding for process control (OPC) alarm to a human machine interface if the deviation exceeds a predetermined deviation tolerance threshold.
