Abstract

The present invention is an access control door controller which utilizes three relays, 16 alarm inputs, tamper switch, a Weigand reader, a RS 232 reader and a IP core module to enable access control alarm monitoring, inter locking of doors and/or energy management for a room with the help of a software. The present invention utilizes a distributed communication (peer to peer) thus creating a door access controller System network with a truly distributed intelligence permitting exchange of information between all controllers which may be situated in a single site or over multiple sites connected on a common network. The full system can be configured on the widely used TCP/IP network thus avoiding the need for extensive wiring traditionally required for Access Control System. The controller, with its associated software can support multiple types of readers and can directly interface IP cameras for an integrated TCP/IP based Access Control/CCTV Solution.

Claims

1. An access control door controller removing the present limitations of a RS 485 networked Access Control Systems by utilizing its embedded software capabilities of recognizing and analyzing the information received simultaneously from both onboard Wiegand data port and RS 232 data port for read and write functions of RF identification devices thus bringing in a greater flexibility in use of varied RFID readers and operating all known Proximity and Smart Card protocols including, but not limited to Wiegand, Mifare, Legic and i-CLASS and utilizing three relays being able to accept 16 alarms input from Sensors and control IP cameras utilizing a software which permits transferring of data from each individual controller working directly on the TCP/IP network to the server thus overcoming the major problem of using multiple door controllers having to use RS485 networks for wiring from individual doors to multiple door controller and operating on all known operating systems/relational data bases working with an independent power supply unit capable of meeting power supply requirements of IP cameras and alarm devices connected in conjunction with the door controller permitting full convergence of Access Control, CCTV and Alarm systems.

2. An access control door controller as claimed in claim no. 1 which has on its printed circuit board three relays that are controlled by the sensor inputs through embedded software, which can be used for controlling three distinct doors simultaneously in a manner such that one door is access controlled whilst the other two doors are interlocked with each other which means that if one door is open the other cannot be opened at the same time as these relays are controlled by sensor inputs through the embedded software.

3. The access control door controller as claimed in claim no. 1 can be directly linked to an IP camera and can provide an associated image from the IP cameras when directed to do so by the access control door controller with said software this hitherto not being possible, as since video cannot be passed over the RS485 networks traditionally used for Access Control.

4. The access control door controller, as claimed in claim 1, through its embedded software, is able to differentiate between 16 different alarm inputs from varied sensors, initiate actions as directed by the embedded software for giving audio visual alarms and uploading the data to the server on the TCP/IP network for display on the screen and historical archiving and permitting corrective action by monitoring personnel.

5. The access control door controller as claimed in claim no. 1 that has the capability for accepting contact less RF identification signals from both Wiegand and RS 232 ports simultaneously or independently thus permitting use of any type of reader used for access control.

6. The access control door controller as claimed in claim no. 1 that can utilize two way communication capabilities of RS 232 port to perform read/write functions as an integrated port of access control, thereby permitting full utilization of contact less RF identification, smart card technology.

7. The access control door controller as claimed in claim no. 1 with its said relays that are capable of controlling the temperature settings for a room by switching on and off a room air conditioner based upon the prevailing temperatures with the help of said software.

8. The access control door controller as claimed in claim no. 1 can be installed on a network of controllers without use of any additional cabling for a RS485 network by utilizing the existing infrastructure and cabling of local area network without any geographical restrictions on the actual location of the controller and uses the TCP/IP network protocol.

9. The access control door controller as claimed in claim no. 1 which works in conjunction with its specific software on multiple operating systems.

10. The access control door controller as claimed in claim no. 1 which can work in conjunction with its specific software on multiple databases.

11. The access control door controller as claimed in claim no. 1 as described in the complete specification accompanied by drawings in the complete specification.
