Definitions

  • the present invention relates to coded entry or access and more particularly access control, security or entry of data logging that involves the validation of a data string.
  • a wireless transmission e.g. radio, infrared, microwave, etc.
  • a receiver which either validates or does not validate the instruction and consequently respectively actuates or does not actuate.
  • the present invention recognises an advantage in having for coded entry and/or access purposes means of wirelessly transmitting a coded transmission (e.g. data string) that will vary each time it is used but not to the confusion of its dedicated receiver and only after such verification proceeding through (by any relay means, wired or wireless) to and/or enabling an ancillary data encryption fo ⁇ nat which has the capability of allowing or causing an action being instructed by and/or substantially together with the original transmission.
  • a coded transmission e.g. data string
  • the present invention consists in an access control system having a capability to validate a coded data string wireless transmission using a code hopping or rolling code algorithm and, if the transmission is validated, causing and/or allowing a function to occur responsive to receipt of another code string.
  • the present invention consists in an access control system that has, in sequence two code recognitions systems, the first to recognise a wireless transmission of a data string and the second to be responsive to a related and/or unrelated data string only upon a validated receipt of the first mentioned data string, wherein the first code recognition system is of a rolling or code hopping type so as to render wireless recording thereof by an authorised person unhelpful without access to the rolling or hoping algorithm.
  • the function control data string is shorter than that initially wirelessly transmitted.
  • the invention consists in an access control system having access function(s) controlled by a coded protocol ("function control protocol”) system, and having a coded protocol reliant on wireless transmission and receipt thereof ("the verification protocol") which code hops or rolls reliant on a relating algorithm, wherein verification by the verification protocol is a prerequisite for access function(s) under the control of the function control protocol being allowed.
  • the function control protocol involves fewer coded bits than the verification protocol.
  • Preferably several transmitters can be verified to enable at least some control of the function control protocol.
  • the function(s) include door opening/closing.
  • verification protocol can be the or a Wiegand protocol.
  • function control protocol can be the or a KEELOQTM protocol.
  • the present invention consists in apparatus of a system in accordance with the present invention.
  • the present invention relates to methods of operating an access control which is reliant upon a system in accordance with the present invention.
  • the present invention consists in the use of apparatus to transmit verification data and/or instruction data as part of the system of the present invention or as part of the method of the present invention.
  • the present invention consists in a door or other access opening responsive to control of the kind contemplated by the present invention.
  • the term "and/or” means “and” or “or”, or both where the circumstances allow.
  • nouns As used herein the term "(s)" following a noun means both or either the plural and singular forms of that noun. As used herein the term “/" between nouns (e.g. as used hereinafter as
  • opening/closing means both the opening and closing functions or either.
  • Wiegand protocol refers to a standard data output format that is an industry standard digital protocol for accessing and transferring data between devices (see published standard of The Security Industry Association of the USA).
  • KEELOQTM refers to a code hopping technology developed specifically for secure remote keyless entry and authentication based on the principle is that the code changes (hops) each time it is transmitted.
  • KEELOQTM is based on a proprietary, non-linear encryption algorithm that creates a unique transmission on every use, rendering code capture and resend schemes useless.
  • the algorithm uses a programmable 64-bit encryption key unique to each device to generate 32-bit hopping code.
  • Figure 1 shows a diagram where a data string wirelessly transmitted is detected and verified or not and it is only upon verification that that data string continues into a different coded protocol to effect functions
  • Figure 2 shows an alternative where simultaneous or substantially simultaneous transmissions ensure verification prior to allowing a separately transmitted data string to activate the different protocol
  • Figure 3 shows a further alternative embodiment whereby a wireless rolling code signal is sent to a receiver which upon positive validation outputs a converted code of a differing rolling code format the signal whether being transmitted in a wired or wireless format then allows access or activates the system, and
  • Figure 4 is a diagram for use in our explanation of some functions and logic features of a preferred implementation of the present invention.
  • Systems in accordance with the present invention preferably link systems such as that marketed under the trade marks Wiegand and KEELOQTM so as to provide for the access control system the synergism of initiation to less secure input data strings only upon recognition of a more secure data string protocol.
  • Such a system will enable more transmitters to be made available without any substantial undermining of security.
  • related functions to initiation can be compounded in the scenario of Figure 1 where, for example the code string of the verification protocol may be say of 34 bits whilst that of the function control protocol may be less than half that.
  • the system converts data transmitted wirelessly, for example from a radio transmitter, keypad, or similar 1, in an encrypted code utilising a rolling or code hopping algorithm (such as KEELOQTM).
  • the data is received and validated by a receiver 2 using the appropriate decryption algorithm and then a signal relayed by any means, wired or wireless, in another data encryption format (such as Wiegand) to another access control, security, entry or data logging system 6 for validation and recording by that system such validation may allow activation of a latch or similar means to then allow access by the user or person who originally transmitted the signal.
  • the system also allows for the receiver to learn and store a number of remote transmitted devices 1. In this way multiple users can gain access with their own code to the system.
  • the system key 1 sends out a 34 bit rolling code signal, such as that generated by the KEELOQTM security protocol, this is then received by a receiver 2 which then validates this signal. If the signal is not validated no code is returned 4. If the validation is positive then an output is generated. In the situation where there is a further receiver 5 such as in Figure 1 this receives the code output from 3 as a 34 bit rolling code signal (whether wired or wireless signal). The second receiver 5 then converts the information from the 34 bit rolling code signal and outputs this as a 24 bit rolling code signal (such as that generated by the Wiegand protocol) which then gives the user access or activates the system.
  • a 34 bit rolling code signal such as that generated by the KEELOQTM security protocol
  • this return 34 bit rolling code signal is received and then converted to a 24 bit rolling code signal by 5 which is transmitted to then activate the system or allow access to the system.
  • a further embodiment allows, upon a positive validation from the receiver 2 generation directly of a 24 bit rolling code system by a conventer 7 which is transmitted either by wired or wireless means to allow further access 6.
  • a high security protocol such as that provided by a 32 bit rolling code system will allow the user upon positive validation of the user, access to or activation of a further system, the activation of or access to that system occurring via a lower security protocol such as a 24 bit rolling code signal.
  • This two layer security system providing a more secure system.
  • the manual control button ideally requires to be continuously depressed to move the door. Successive presses result in reversal of door travel direction. This ensures that the door can not accidentally be moved beyond the correct physical end- points of travel.
  • controller inputs, outputs, and parameters are relevant:
  • controller can infer the position, speed and direction of the door's travel.
  • the controller can infer the position, speed and direction of the door's travel.
  • the motor's torque-speed, and torque-current characteristics the load placed on the motor can be inferred for any position of the door's travel.
  • the controller If the controller has been reset, it can not determine whether its stored relative position is correct so it must recalibrate to the reference position. In order to decide which direction to travel first it checks the state of the reference switch and then moves towards the reference point. Once the reference switch has changed state, normal operation resumes. The user will be unaware of this unless they stop the door and try to move the door in the opposite direction before the reference switch changes state. In this circumstance the user will be required to continuously depress the manual control button. On every uninterrupted operation from a limit position the counter will be set to zero at the reference switch. The counter values for the open and closed limits will be referenced to the newly calibrated reference position. See Figure 8.
  • the motor speed and/or current is stored with door position during setup. If during normal operation within a short distance of the bottom limit the speed and/or current does not match the stored values within some percentage then the physical limit position is judged to have been altered. The new limit position replaces the old limit position counter value.
