Description




BACKGROUND AND SUMMARY OF THE INVENTION




The present invention relates to a security control system. More particularly, the present invention relates to a wireless security control system that grants or denies access to a user seeking access through a door.




In the access control and security industries, there are two types of access control systems: on-line systems and standalone systems. On-line systems perform access grant and deny functions and history recording and provide continuous monitoring of a secured door or portal with nearly instantaneous updating of user access privileges. Standalone systems perform many of the basic functions of on-line systems (access grant & deny, history recording, etc.) but generally do not provide continuous monitoring or instantaneous updating of user access privileges.




On-line systems cost three to four times more than standalone systems mainly because hard-wired connections are required to connect readers, sensors, and locking devices at the door to either a “panel” or central computer. The use of wires allows for continuous monitoring and instantaneous updating of user data, but at an inflated cost. Standalone systems maintain a cost advantage by being battery-powered and avoiding the use of wires. The main disadvantage of traditional Standalone systems is that if the user data needs to be updated, an individual must walk to and physically connect to the Standalone systems. Once connected, new user data can be downloaded into the system via a laptop, palmtop, or custom programming device.




Through the use of wireless radio frequency (“RF”) technology, the present standalone security systems can perform user data updates and some monitoring on an as required basis. For RF wireless technology to be effectively implemented on standalone systems, battery power must be conserved. In preferred embodiments, the standalone system should maintain an appealing physical appearance. For example, any antennas should be hidden or unobtrusive.




A remote access control system includes a remote wireless communicator to receive wireless information from a central access control system. It also includes a remote access controller electrically coupled to the remote wireless communicator. The remote access controller would receive information from the remote wireless communicator and uses the information to control locking and unlocking of the door. The remote wireless communicator includes an antenna. A receiver housing is providing having an inner portion mounted to the inside of the door and an outer portion mounted outside of the door. The antenna is mounted to the outer portion of the housing and the remote wireless communicator and remote access controller are mounted to the inner portion of the housing. The remote wireless communicator also transmits wireless information to the central access control system and a switch is provided for selectively choosing between the receiving and transmitting the wireless information. A local communication port is coupled to the remote access controller to provide wired communication from a portable device. The remote wireless communicator communicates via RF information and preferably spread-spectrum RF.




The remote access control system also includes a reader to read user data when presented to the reader. The remote access controller determines whether the data is valid to control the locking and unlocking of the door. A battery is coupled to the reader, the remote access controller and the remote wireless communicator. The remote access communicator selectively connects the battery to the remote wireless communicator to conserve energy. The reader is mounted to the outer portion of the housing. The user data is provided on a token control card presented to the reader.




The central access security system includes the remote access system and a central access control system. The central access control system has a central access controller and a central wireless communicator. The central wireless communicator communicates with the remote wireless communicator. The central access controller is coupled to the central access communicator by a bus. The bus may be a wired network using network protocol, fiber optics, or a wireless bus. The system may include a plurality of central wireless communicators coupled to the bus and the central access controller. Each central wireless communicator may communicate wirelessly with one or more remote wireless communicators.











Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS




A wireless security control system


10


is shown in FIG.


1


. The wireless security control system


10


controls whether a particular user


12


will be granted or denied access through a particular door


14


. As shown in

FIG. 1

, user


12


is granted access by the wireless security control system


10


to pass through one of the doors


14


because user


12


properly presented a valid user data on a token


13


for example, to a remote access control system


22


mounted on door


14


which allowed user


12


to open door


14


.




The wireless security control system


10


of the present invention includes a central access control system


20


and a plurality of remote access control systems


22


located remotely from central access control system


20


. The central access control system


20


uses wireless communication technology to communicate with each remote access control system


22


. The central access control system


20


can therefore be used to program each remote access control system


22


so that certain users are granted access through certain doors


14


and other users


12


are granted access through other doors


14


. The central access control system


20


can also receive information from each remote access control system


22


so that user access information such as the time and date that a particular user


12


was granted access through door


14


can be tracked and monitored.




Each remote access control system or electronic lockset


22


is mounted to a respective door


14


to control whether the particular user


12


is granted or denied access through the particular door


14


, as shown in FIG.


1


. Remote access control system


22


will grant user


12


access through door


14


if user


12


properly presents valid user data for example on a token


13


to remote access control system


22


. If the data on token


13


is deemed by remote access control system


22


to be valid, a lock mechanism


15


mounted to door


14


will be unlocked and the user will be granted access to pass through door


14


, as shown in FIG.


1


. However, if remote access control system


22


deems user data on token


13


to be invalid, or if token


13


is not properly presented to remote access control system


22


, lock mechanism


15


on door


14


will remain locked and user


12


will not be granted access through door


14


.




As shown illustratively in FIG.


1


and diagrammatically in

FIG. 2

, central access control system


20


includes a central access controller


30


, a central wireless communicator


32


, and a power and/or signal bus


36


that electrically interconnects central access controller


30


and central wireless communicator


32


. Central wireless communicator


32


allows information to be communicated wirelessly between central access controller


30


and each remote access controller


22


. The central access controller


30


is configured to communicate bidirectionally with one or more central wireless communicators


32


, as shown in

FIG. 2

by a double-headed arrow


34


interconnecting central access controller


30


and central wireless communicator


32


. This bidirectional communication allows information to be transmitted from central access controller


30


to central wireless communicator


32


and/or received by central access controller


30


from central wireless communicator


32


.




As shown in

FIG. 1

, bus


36


can simply be a hard wire connection between central access controller


30


and central wireless communicator


32


. However, as shown diagrammatically in

FIG. 4

, bus


36


can also electrically interconnect central access controller


30


and central wireless communicator


32


using RF technology, fiber optics, coaxial cable, A/C power line, regular wire, twisted pair wire, or any other suitable electrical connection. A variety of different protocols such as CE bus, LON works™, TCP/IP, IPX/SPX, or custom protocols, can be used to transfer information from central access controller


30


to a plurality central wireless communicators


32


over one of the electrical connections mentioned above. Each central wireless communicator


32


communicates wirelessly with one or more remote access control system


22


.




Each remote access control system


22


is configured to communicate wirelessly and bidirectionally with one of the central wireless communicators


32


of central access control system


20


, as shown in

FIG. 2

by a double-headed arrow


58


interconnecting central wireless communicator


32


and remote access control system


22


. As shown in

FIG. 2

, each remote access control system


22


includes a remote wireless communicator


60


, a remote access controller


62


, a user input device or token reader


64


, and lock mechanism


15


. The remote wireless communicator


60


is configured to communicate information wirelessly and bidirectionally to/from central wireless communicator


32


. Because central and remote wireless communicators


32


,


60


communicate wirelessly with one another, each remote access control system


22


can be a standalone unit which is located remotely from central access control system


20


, as shown illustratively in FIG.


1


. In other words, each remote access control system


22


does not have to be connected to central access control system


20


using hard-wire connections. Therefore, wire for connecting a remote access control system mounted to a door with a central access control system does not have to be pulled in a building where the wireless security control system


10


is installed.




Remote access controller


62


is configured to communicate bidirectionally with remote wireless communicator


60


, as shown in

FIG. 2

by double-headed arrow


68


. Thus, remote access controller


62


can send or receive information to or from central access controller


30


through remote and central wireless communicators


60


,


32


. This allows remote access controller


62


to send periodic user access information to central access controller


30


while also allowing central access controller


30


to change the programming of remote access controller


62


by, for example, determining which tokens


13


have access to which doors


14


.




As shown in

FIG. 2

, token reader or user input device


64


is adapted to read data stored on token


13


and transmit the data to remote access controller


62


. If the data from token


13


is determined by the remote access controller


62


to be valid, the remote access controller


62


will send an “unlock” signal to lock mechanism


15


mounted to door


14


. With lock mechanism


15


in an unlocked position, user


12


is able to open door


14


. Token reader


64


can be a card reader as shown in

FIG. 1

, or any other device which interprets token data to permit an authorized user to access a controlled door. For example, token reader


64


may be a keypad configured to receive token or user data by having user


12


key in a particular code, or a fingerprint reader configured to read a user's fingerprint which serves as the user data, or a retinal scanner configured to read a user's retina which serves as the user data. In addition, token reader


64


may be, for example, any of the following types of readers: magnetic stripe, proximity card, smart card, touch memory, and biometric which includes handprint, eye, facial recognition, facial blood flow, and voice.




As mentioned above, information can be communicated wirelessly from central access control system


20


to remote access control system


22


to allow central access control system


20


to program remote access control system


22


. Basically, this involves central access controller


30


sending information to remote access controller


62


via central and remote wireless communicators


32


,


60


. This type of wireless communication allows the remote access control system


22


to be programmed by the central access control system


20


so that remote access controller


62


locks and unlocks door


14


only for approved users


12


having approved tokens


13


as directed by central access controller


30


.




Information can also be communicated wirelessly from remote access controller


62


to central access control system


20


. This involves a signal being sent from remote access controller


62


to central access controller


30


via remote and central wireless communicators


60


,


32


. This type of wireless communication allows user access information to be monitored and tracked by passing information received by remote access controller


62


from token reader


64


to central access controller


30


.




A preferred embodiment of the wireless security control system


10


is shown in FIG.


3


. As shown in

FIG. 3

, remote access control system


22


of wireless security control system


10


is mounted to door


14


to control the locking and unlocking of lock mechanism


15


which is also mounted to door


14


. Remote access control system


22


includes a housing


69


having an outer plate or housing


73


and an inner plate or housing


74


. Outer plate


73


mounts token reader


64


and antenna


71


to an exterior side of door


14


. Antenna


71


may be mounted to either the interior or exterior side of door


14


. Inner plate


74


mounts transmit/receive circuit


70


, remote access controller


62


, and a battery


66


to an interior side of door


14


.




Outer and inner plates


73


,


74


are each formed to include an aperture or hole


75


,


76


, respectively, to accommodate lock mechanism


15


, as shown in FIG.


3


. Lock mechanism


15


is mounted to door


14


and is used to latch and lock door


14


. Lock mechanism


15


includes an outer door handle


46


, an inner door handle


47


, a latch bolt retractor assembly


48


, a latch bolt


49


, and a spindle


50


. Lock mechanism


15


is operable by means of either outer door handle


46


or inner door handle


47


to operate centrally-located latch bolt retractor assembly


48


. The latch bolt retractor assembly


48


is mounted in door


14


and is connected to spring-biased latch bolt


49


. Latch bolt retractor assembly


48


is electrically coupled to remote access controller


62


using a wire


91


so that control signals can be sent from remote access controller


62


to latch bolt retractor assembly


48


to move latch bolt retractor assembly


48


between a locked position and an unlocked position. In the unlocked position, latch bolt retractor assembly


48


can be operated by either inner or outer door handle


46


,


47


to retract latch bolt


49


from its projected position (shown in

FIG. 3

) engaging a door frame (not shown) to a retracted position (not shown) lying inside door


14


and disengaging the door frame.




As shown in

FIG. 3

, spindle


50


is arranged to extend through latch bolt retractor assembly


48


and interconnect outer door handle


46


and inner door handle


47


. When latch bolt retractor assembly


48


is in the unlocked position, rotation of either of the door handles


46


,


47


, rotates spindle


50


to operate latch bolt retractor assembly


48


and move latch bolt


49


from the projected position to the retracted position. Lock mechanism


15


is a mortise lockset. However, lock mechanism


15


could be any type of lock mechanism including, but not limited to: cylindrical lock mechanisms similar to those disclosed in U.S. Pat. Nos. 5,590,555; 5,794,472; 5,421,178; and 4,428,212, which are incorporated herein by reference or mortise lock mechanisms similar to those disclosed in U.S. Pat. Nos. 5,474,348; 4,589,691; and 4,389,061, which are incorporated herein by reference.




Inner plate


74


is also formed to include an opening


78


designed to allow access to various portions of remote access control system


22


during assembly or removal of remote access control system


22


to or from door


14


, respectively. A cover (or cap)


77


is configured to cover opening


78


formed in inner plate


74


once remote access control system


22


is mounted to door


14


.




As shown in

FIG. 3

, remote access controller


62


is mounted to inner plate


74


and is electrically coupled to token reader


64


by a wire


90


. As discussed above, any suitable token reader may be used. As shown in

FIGS. 3 and 4

, remote wireless communicator


60


of remote access control system


22


includes a transmit/receive circuit


70


, an antenna


71


, and a wire


72


electrically interconnecting transmit/receive circuit


70


with antenna


71


. As shown in

FIG. 3

, transmit/receive circuit


70


is mounted to inner plate


74


and antenna


71


is mounted to outer plate


73


. Wire


72


extends through a hole


79


in door


14


to interconnect transmit/receive circuit


70


with antenna


71


.




Transmit/receive circuit


70


is used to communicate (e.g., transmit and receive) information between remote access controller


62


and central wireless communicator


32


through antenna


71


, as shown in

FIGS. 3 and 4

. As shown in

FIG. 4

, transmit/receive circuit


70


includes a transmitter


80


, a receiver


82


, and a switch


84


. Transmitter


80


is electrically coupled between remote access controller


62


and switch


84


, as shown in

FIG. 4

, so that remote access controller


62


can transmit information through switch


84


and antenna


71


to central wireless communicator


32


. Similarly, receiver


82


is electrically coupled between remote access controller


62


and switch


84


so that wireless information transmitted by central access controller


30


through central wireless communicator


32


can be received by remote access controller


62


through antenna


71


and receiver


82


. Switch


84


simply disconnects the path between transmitter


80


and receiver


82


to prevent electrical overload of receiver


82


.




Transmitter


80


, receiver


82


, and antenna


71


can be any variety of devices that cooperate to transmit and receive wireless information. For example, transmitter


80


and receiver


82


could use infrared, ultrasonic, magnetic, or radio frequency (RF). Preferably, as shown in

FIGS. 1 and 3

, RF technology is used. For RF applications, antenna


71


could be a patch, loop, monopole, dipole whip, printed circuit whip (stub), helical (coil), chip, or slot antenna. As shown in

FIGS. 1 and 3

, antenna


71


should maintain the aesthetic appeal of the unit while providing adequate RF performance. Switch


84


can also be a wide variety of switches for switching the flow of information from transmit to receive, or vice versa. For example switch


84


could be a specialized RF switch or PIN diodes.




There are many types of RF technology that could be used to configure transmitter


80


and receiver


82


for wireless communication. For example, the following types of RF technology could be used: frequency modulation (FM), amplitude modulation (AM), amplitude shift keying (ASK), frequency shift keying (FSK), phased shift keying (PSK), single band transmission, dual band transmission, and spread spectrum transmission. Spread spectrum technology is resistant to interference, jamming, and multi-path fading. In the preferred embodiment, the 902-928 MHZ frequency range was selected because it is within the FCC spectrum. Spread spectrum technology makes communication between central wireless communicator


32


and remote wireless communicator


60


more reliable than the other RF transmission technologies mentioned above. In preferred embodiments, the present invention uses spread spectrum technology that is commercially available from Intellon Corp., located in Ocala, Fla. Familiar uses of spread spectrum technology include pagers, cordless telephones, and cellular telephones.




Battery


66


is mounted to inner plate


74


, as shown in FIG.


3


. Battery


66


provides power to remote access controller


62


, token reader


64


, and user history module


98


, as shown in

FIGS. 3 and 4

. Battery


66


also provides power to remote wireless communicator


60


through remote access controller


62


. Remote access controller


62


includes a switch


67


, as shown in

FIG. 4

, to control when power is applied to remote wireless communicator


60


. Because battery


66


provides all the power required by remote access control system


22


, the expense associated with pulling wires throughout a building to provide power to a remote access control system is eliminated. The remote access control system of the present invention could receive power by being hard-wired to a power source located away from door


14


, but one of the cost advantages of remote access control system


22


would be lost by doing so. The major cost advantage is elimination of the wire connection between the remote access control system and the central access control system.




Remote access control system


22


is configured to conserve energy drawn from battery


66


. This is done by checking for user updates periodically (once a day, once an hour, etc.) and reporting only high priority events to central access control system


20


on a real-time basis. This contrasts with continuously polling remote access control system


22


and communicating to central access control system


20


every time a decision is to be made.




The security control system


10


of the present invention allows for distributed decision making by having a single central access control system


20


and a plurality of remote access control systems


22


. Distributed decision making is possible because each remote access control system


22


decides independently whether a particular user


12


or token


13


is granted or denied access through the door


14


to which remote access control system


22


is coupled. The remote access control system


22


does not need authorization from central access control system


20


before making a decision. Therefore, the distributed decision making capability increases the speed of the decision making process because the remote access control system


22


makes the grant or deny decision locally, at the door


14


, without having to communicate with central access control system


20


.




The distributed decision making capability of security control system


10


also allows for better degrade mode performance. In other words, the distributed decision making capability prevents a failure of a single component from shutting down the entire security control system


10


. For example, by having several remote access control systems


22


that make decisions independently from central access control system


20


, the failure of a single component within a single remote access control system


22


or within the central access control system


20


is less likely to shut down the entire security control system


10


than if all the decision making were done by a central access control system.




The distributed decision making capability also minimizes power consumption of battery


66


in a wireless system since the remote access control system or lockset


22


does not have to power up the remote wireless communicator


60


every time a token


13


is presented to remote access control system


22


. As mentioned above, remote wireless communicator


60


is powered up by remote access controller


62


only when wireless communication is desired and remains powered down during the normal access grant or deny decision making process. This contrasts with a centralized decision making system where wireless communication would be needed each time a token is presented to a remote lockset which would naturally reduce the life of the battery.




As shown in

FIGS. 3 and 4

, remote access control system


22


may also include a local communication port


92


mounted to outer plate


73


and electrically coupled to remote access controller


62


by a wire


93


so that a transport device


94


can be connected to remote access control system


22


. Transport device


94


is used to transfer information (such as configuration data) from the central access controller


30


to the remote access controller


62


. For example, a security administrator would determine the user's access control privileges for a particular remote access control system or lockset


22


. This information is normally kept at a central location, such as the central access control system


20


. When programming the remote access controller


62


is determined necessary, the administrator would transfer the information to transport device


94


(which could be a laptop, a palmtop, etc.), physically take the transfer device


94


to the remote access control system


22


, connect the transport device


94


to the local communication port


92


, and transfer data from the transport device


94


to remote access controller


62


. Of course, the same data transfer could occur wirelessly through central and remote wireless communicators


32


,


60


.




Remote access control system


22


may also include a user history module


98


, as shown in FIG.


4


. User history module


98


allows remote access controller


62


to track information such as which tokens


13


were granted access through which doors


14


on what date and at what time. This user history information from module


98


can then be transmitted to either central access control system


20


or local access control system or transport device


94


on an as-needed basis or on a regularly-scheduled basis (such as once a day, once a week, or once a month).




In operation, user


12


presents user information on a token


13


to token reader


64


. Presentation of token


13


to reader


64


is sensed by token reader


64


and activates or “wakes-up” remote access controller


62


. An illustrative device for sensing a token reader with a wake-up circuit is disclosed in U.S. patent application Ser. No. 09/243,772 entitled “Proximity Card Detection System,” the disclosure of which is incorporated herein by reference. Token


13


is read by token reader


64


and user data (retrieved from the token) is sent to remote access controller


62


. Remote access controller


62


evaluates the user data and performs an access grant or deny decision. If an access grant decision is made, remote access controller


62


applies an unlocking signal to lock mechanism


15


and allows user


12


to gain access through door


14


. After a predetermined period of time, a locking signal is applied to lock mechanism


15


to re-lock door


14


. If an access deny decision is made, no action is taken on lock mechanism


15


. The results of the transaction are stored in user history


98


contained in remote access controller


62


.




On a predetermined time period (minute, hour, day, week), remote access controller


62


is activated by a real-time clock. Activation of remote access controller


62


for this particular reason initiates a data transfer via RF from remote access control system


22


to central access control system


20


. Remote access control system


22


inquires for any updates to the user database and transfers any transaction history events requested by central access control system


20


.




In the case of user updates, remote access control system


22


switches into the RF receive mode and processes data received from central access control system


20


. This data is transferred into the user memory


98


of remote access control system


22


and stored. If central access control system


20


requested history transaction information, remote access control system


22


recalls information from the history or user memory


98


and transmits the data via RF to central access control system


20


.




When data transmission from remote access control system


22


to central access control system


20


is desired, data from remote access controller


62


is processed and modulated using spread spectrum techniques and communicated through antenna


71


. This data is received by central wireless communicator


32


and demodulated back into a digital data stream. This data stream is passed along to central access controller


30


and processed. Information is passed along via a series of commands and protocols similar to those used by LAN networks, as described above.




Conversely, when central access controller


30


wishes to communicate with remote access controller


62


, a data stream is transmitted from central access controller


30


to central wireless communicator


32


. The data is modulated using spread spectrum techniques and communicated through central wireless communicator


32


. This data is received by remote wireless communicator


60


and demodulated back into a digital data stream. This data stream is passed along to remote access controller


62


and processed.




By combining RF wireless technology with a battery powered access control system, the elimination of wires in standard access control products is eliminated or greatly reduced. Additionally, because remote access controller


62


contains intelligence, remote access controller


62


can make all access control decisions at the door. This intelligence eliminates the need to transmit and/or receive data via RF for each event that occurs at the door. This feature greatly reduces the amount of power draw required by a battery powered device.
