Definitions

  • the advantages of electronic lock systems over their mechanical counterparts are obvious in that the electronic lock systems offer greater protection in guarding against unauthorized entry, key duplication and lock picking.
  • the prior art electronic lock systems in general, include an electronic control circuit which responds to a coded card, or other coded key, to operate an electromechanical latch,
  • the cards in the prior art systems are usually coded optically, magnetically, electrostatically, or capacitively.
  • United States Patent 3,821,704 discloses an electronic lock system in which the electronic control circuit in each door can be readily changed to respond to new codes. This is an essential requirement in hotels, in order that each new guest may be issued a card bearing a new code which will be effective to open a particular door, and which will cause the card issued to the previous guest to be no longer effective in operating the door.
  • a feature in the system described in the patent is that when the new guest inserts his card into the slot in the door of the room assigned to him, the insertion causes the unit in the door to be changed to respond to the new code encoded into the card of the new guest, and to be no longer responsive to the code encoded into the card issued to the previous guest.
  • each lock is controlled by a decoding device which includes a resettable memory.
  • the memory is pre-set with a multi-bit combination.
  • the key number is found to match the combination previously stored in the particular decoding device, the lock of the corresponding door will be activated. If such a match is not made, a comparison is then made between the authorization number on the card and an authorization number entered by the previous user. If the comparison is established, the decoding device is reset to the new key number, so that the lock may be opened by the new card.
  • the electronic lock system of the present invention is of the same general type as described in United States Patent 3,821,704.

  • Each unit in accordance with the concepts of the present invention, is also capable of identifying and recording the time of all entries into the room, and of limiting the number of days the card issued to any particular guest is effective,
  • the key cards used in the electronic lock system of the invention are magnetically encoded, and they are reprogrammable and may be used many times, Data on each card is proximity sensed by a non-contact electromagnetic read head, when the key card is inserted into a slot in any one of the electronic lock door units, so that the read head does not contact the magnetic material in the card and the problems of ambiguous data transfer due to dust, dirt, grease and the like, are eliminated, such problems being common to the prior art key card reading systems, whether magnetic strip, optical or capacitance encoding of the individual cards is used,
  • the individual bits on the card used in the system of the invention are sufficiently loosely packed so that the information may be written into the card and read from the card by manual movement of the card without any need for drive motors or the like.
  • each unit may be constructed so that the key cards may be inserted into the slot with either face up,
  • the card may also be programmed with a guest's identity and sent to the guest when a reservation is made. Then, upon entering the hotel, the guest need merely insert his card into a card reader to complete check-in and to receive his room assignment,, On check-out the guest merely inserts his card into the reader and his billing information is automatically recorded and he is provided with a print-out,
  • a portable computer is provided which may be hand carried to any door and plugged into the electronic control unit in that door to read identification and time data stored in the unit, and also to re-program the door unit if necessary, and to program the unit door for an initial use.

  • the transistor Ql remains conductive while the card is being withdrawn from the slot, and until all the bits on the card have been read, after which the transistor Ql again becomes non-conductive,
  • the tran sistor Q2 is intermittently energized, and causes the LED CR3 to flash.
  • the flashing continues, for example, for 5 seconds.

  • the door must then be opened during the 5 seconds while the LED CR3 is flashing.
  • the transistor Q3 is again rendered non-conductive, de-energizing the solenaid.
  • the rows A and B of the magnetic card 16 represent the data bits, and the center row C represents the clock bits. Accordingly, of the total bits which represent the data code, a certain number are used for the entry code, and the remaining bits are used for an identification code.
  • the microcomputer MC10 responds to the entry code on the card to make a comparison with the code stored in its memory, and if a comparison is achieved, causes the transistor Q3 to be rendered conductive so as to energize the door unlocking solenoid S10.
  • the microcomputer also responds to the identification code bits to store in its memory, identification data including information relating to the time of each entry, and whether the key used was a service key, a maid t s key, or a guest's key,
  • the microcomputer 10 stores five levels of key codes in a constructed embodiment of the invention.

  • each new guest is issued a card, and his card will activate but a single door.
  • each maid is issued a card, and her card will activate a predetermined number of doors when the privacy switch has not been activated.
  • the master level cards will, for example, activate all the doors to permit servicing unless the privacy switch has been activated; whereas the emergency level cards will activate the doors even though the privacy switch 30 has been activated, in order to gain access to the room under all conditions.
  • magnetic armature cards means that the cards may be reprogrammed and used many times, which reduces card cost, as compared with the single use card,
  • the data on the card is proximity sensed, as mentioned above, eliminating the need for the reader heads to touch the card which, as mentioned, eliminates the problems of ambiguous data transfer due to dust, dirt, grease, and the other environmental problems common to electronic readers, whether magnetic strip, optical or capacitance,
  • the code on his card is stepped by one or two on the binary scale, as compared with the previous card, Then, when the new guest inserts his card into the slot, the door unit responds to his card to unlock the door, and at the same time sets a register in the microcomputer 10 so that the system will no longer respond to the preceding card. Even though the change of code from one card to the next in the constructed embodiment of the system is "1" or "2" on the binary scale, unauthorized entry can still be prevented by providing no indication on the card as to the position of the most significant bit or of the other bits of lesser significance,
  • the microcomputer 10 will read the card and record the time and identity of each person entering the room, for example, for the last fourteen entries. Specifically, the microcomputer will indicate whether the person entering the room was a guest, a maid, service personnel or emergency personnel, In the case of hotel personnel, each. is identified, because of identification data recorded on their cards, By being able to read the card and record the last fourteen entries, the list of suspects of any burglary, or the like, is narrowed, which acts as a significant deterent to prevent burglary by hotel employees. As mentioned above, the identification and time data is read from each unit by the computer of FIGURE 5.
  • the door unit When the new card is inserted into slot 12 of FIGURE 1, the door unit will read the new code on the card and change the current code by one or more on the binary scale so that the old card will no longer be accepted. Provision may be made for the situation in which a card is issued for a particular room which is not used, so that the unit in the door does not have the opportunity of up-dating the current code, This is achieved by causing the system in the door to accept the current code, the current code plus 1 binary unit, and the current code plus 2 binary units. Therefore, even though the current code has not been up-dated by the previously issued card, it will still accept the new card,
  • computer 100 of FIGURE 5 is preferably small and portable so that is can be carried to the individual doors when the occasion arises and plugged into the individual door units.
  • the microcomputer 'unit MC10 in each door unit has a small memory which stores data as to the identities and times of the last fourteen entries into the room, The computer can be plugged into the door unit to read out this information, Also, as mentioned above, the computer can be used to program or re-program the door unit,
  • Lithium batteries do not gradually lose potential when they begin to fail, Instead, the potential immediately drops to zero. For that reason, a battery indicator circuit is included in the system of FIGURE 3. This circuit includes capacitor C2 which is charged through resistor R14 by the battery 26. The resulting voltage across the capacitor powers the microcomputer MC10.,
  • the internal resistance of the battery 26 increases as it begins to fail, Therefore, its voltage will drop when failure is imminent during the time it is loaded by solenoid S10.
  • Comparator A4 is used to look at the voltage of battery 26 when it is loaded by solenoid S10, If that voltage drops below a certain threshold, the code register in the memory of the microcomputer MC1Q is set to zero and the door unit will not accept any code. Then, when computer 100 is plugged into the system, it can open the door.
  • Microcomputer MC10 includes an internal register, and whenever a card is inserted into slot 12 of FIGURE 1, the entrance code on the card is entered into the register,
  • the microcomputer also includes a first internal counter which is set to the proper entrance code of the door. When a guest inserts his card into slot 12 of FIGURE 1, and when the entrance code on his card matches the code in the counter, pin PA2 goes low and solenoid S10 is energized and the door may be opened.
  • the solenoid In order to preserve power, the solenoid is first energized by a 50. millisecond D,C, pulse-to cause it to latch; thereafter a 1 KHz square wave with a 50% duty cycle appears at pin PA2 for five seconds to hold the solenoid latched, The solenoid obviously draws less current from battery 26.during the square wave as compared with the duration of the initial D.C. pulse,
  • Microcomputer MC10 also includes a second internal counter which is set, for example, to one binary count greater or less than the first interval counter, or to any predetermined number of counts greater or less than the first counter. If the next guest inserts his card into slot 12, and if the entrance code on his card matches any count inclusive between the first and second counters, solenoid S10 is energized and the door may be opened. The two counters are then stepped so that the count on the first counter matches the entrance code on the new guest card, and so that the count of the second counter is greater or less than the new count of the first counter by the predetermined number of counts.
  • Each guest card has a second code encoded on his card representing the duration of his authorized occupancy of the room. As he inserts his card into slot 12, another counter is set in accordance with the duration code, This latter counter is then counted down to zero by the internal clock of the computer. When the counter reaches zero, it increments or decrements the previously described counters by the predetermined amount, and the present card is no longer effective,
  • Computer MC10. also includes an internal maid's entrance register which is set to a particular code, When a maid's card is inserted into slot 12 having a code.matching the particular code, solenoid S10 is energized and the door may be opened. Each maid's card also has an identity code which identifies the holder. This code is stored in the computer's memory, together with the time of access, The microcomputer MC10, however, will not respond to the maid's card if the privacy switch 30 is closed.
  • a similar internal register and identity storage is provided within the computer for the master cards, and for the emergency card, As noted above, the emergency card will operate the solenoid SlO. even though the privacy switch 30 is closed.
  • the microcomputer MC10 includes a clock generator controlled by crystal Xl, and counting circuitry for indicating real time, so that the time of the various entries can also be stored in its memory,
  • the unit in the door records every entry into the room on an elapsed time basis.
  • the computer responds to the elapsed time readings of the door unit to provide a read-out of the real time of each entry,
  • the invention provides, therefore, an electronic lock system in which each door has its own self-contained microcomputer controlled unit which is not wired to a central computer, and which is battery operated by a self-contained battery.
  • the unit is small and light, and it may be readily removed from the door and replaced as a single unit, should the need arise,
  • the system of the invention is conceived so that the individual guest cards can be programmed to expire after a selected time interval. Also, non-use of any issued guest card will not affect the operation of the system. In addition, the individual door units keep a record of the identities of all hotel personnel entering the corresponding room, and the times of each access.
  • the desk computer electronically codes each guest card as it is issued, and it eliminates mechanical card punches.
  • the card itself is a simple, programmable metal card which is magnetically encoded and which is read on a proximity basis with. no moving parts in the reader, The card can be re-programmed and re-used countless times,
  • the desk computer is small and light and readily portable. It can be carried to any particular door and plugged into the door unit, as described above, to read information stored in the door unit, and to start up the door unit.
