Definitions

  • This invention relates to an elevator safety chain in which the status or condition of a monitored safety-related parameter of the elevator is communicated by wireless transmission from an interrogated, passive RFID.
  • the safety chain of literally every elevator comprises a series of switches, all of which must be made (closed) so that the entire safety chain is a closed, conductive circuit, otherwise, the elevator is prevented from operating.
  • elevator safety chains comprised a plurality of discrete switches, each of which have a moveable contact which connects between a pair of circuits when a parameter is in a safe condition, and which disconnects from at least one circuit in the safety chain when the parameter is no longer in a safe condition.
  • Examples of switches in the safety chain are hoistway door lock switches, elevator door switch, emergency stop switch, inspection switch on the top of a cab, upper and lower hoistway limit switches, and the overspeed switch.
  • the various switches are interconnected by wiring, which in turn must conform to local government regulation codes with respect to size and location of wires and conduits. Furthermore, once a building is wired to provide a safety chain, it is difficult to alter the building configuration, or the architectural design of the landings, due to the imbedded wiring.
  • the elevator and hoistway door lock switches must be mounted on the doors themselves, and therefore are connected by flexible wiring either to the cab or to the building, as the case may be.
  • each parameter related to elevator safety has a sensor related to a wireless communication means, such as transceivers, so that when the monitored parameter becomes unsafe, the condition of the sensor causes the transceiver to be switched off.
  • a master transceiver related to the elevator controller sends a token to a first transceiver, which in turn will send it to the next transceiver, and so forth.
  • Power for the transceivers may be supplied by hardwire to the building power, by passive battery, or by a battery system which is recharged by inductive coupling, such as with a recharging circuit disposed on the elevator car.
  • hardwired power obviates the advantage of a wireless system, in that wires supplied for power are as inconvenient as wires interconnecting the safety chain switches. Battery operation requires far too much maintenance, cost and environmental impact. Inductively coupled recharging systems are complex and unreliable.
  • Objects of the invention include a safety chain: having components which rely on neither hardwired power nor batteries; which are passive; in which sensing of the unsafe condition may be integral with the related transceiver; providing improved flexibility, low cost, low maintenance, and ease of upgrading at low cost.
  • Other objects include provision of: improved communication of elevator service calls; integrated wireless transmission of elevator service calls; and simplified, passive communication of elevator service calls.
  • transceivers related to various conditions monitored by an elevator safety chain and related to call buttons are passive, comprising, for instance, radio frequency identification devices (RFIDs).
  • RFIDs radio frequency identification devices
  • a switch which becomes open upon the existence of an unsafe elevator condition may be connected directly with, or incorporated into the related passive transceiver.
  • the sensing of an unsafe condition may be an integral part of the passive transceiver; an example is the use of adjacent structural parts of the elevator (such as a door component) to either tune or detune the frequency determining circuit of the passive transceiver so as to communicate the safe or unsafe condition of the corresponding elevator parameter.
  • the RFID is powered by the received electromagnetic energy, and may respond only to a signal of its own unique frequency, or to a signal on a common frequency which however has an address code unique to the individual RFID.
  • the RFID will then respond by transmitting a signal which may contain its address and which, in this case, will contain the condition of the related parameter, in the safety chain or a call button. If an address is not appropriate, the frequency of the RFID will identify the source of the response.
  • a hoistway 11 of an elevator system includes a plurality of hoistway doors 12, 13, there being one set 12, 13 for each landing.
  • Each set has a passive transmitter 15, such as an RFID, associated with the corresponding hoistway door lock.
  • the condition of the door lock is part of the safety chain; if any of the hoistway doors are not locked, the elevator safety chain will fail.
  • Each landing also has an up hall call button with a related transceiver 14 or a down hall call button with a related transceiver 19, or both.
  • the hoistway also has disposed therein a plurality of transceivers 16 related to upper limit switches and a plurality of transceivers 17, 18 related to lower limit switches.
  • a transceiver 23 is in wired communication with the elevator car controller 24, and communicates with other transceivers and passive transmitters in the elevator system.
  • a transceiver 26 may interrogate the condition of the hoistway doors for the three lowest floors by sending out signals either on a unique frequency or with a unique address code so as to successively interrogate the status of each related door lock as reflected by the corresponding one of the passive transmitters 15.
  • the transceiver 26 may interrogate the passive transmitters 17, 18 related to the lower limit switches.
  • a transceiver 27 may interrogate the passive transmitters 15 related to the hoistway door locks of the upper three floors, and may interrogate the passive transmitters 16 to provide indications of the condition of the upper limits.
  • the transceiver 23 will then receive communications from the transceivers 26, 27 indicative of the various passive transmitter responses in the hoistway.
  • the transceiver 23 may also interrogate the passive transmitter 22 to determine the condition of the related overspeed sensor.
  • additional transceivers such as transceivers 26, 27 may be provided so as to be within range of all of the transceivers 15 in the hoistway.
  • an elevator car 30 has a pair of doors 30, 32 and an RFID 33 related to the car door lock switch.
  • the elevator car 30 also has a plurality of car call buttons with related RFIDs 34, and an emergency stop switch with a related RFID 35.
  • an inspection switch on the top of the cab, and in this case, an RFID 36 related thereto.
  • the RFIDs 33-36 will be interrogated by any of the transceivers 23, 26, 27. There are other conditions in the elevator which are monitored within the safety chain, which are not shown herein for clarity.
  • the RFIDs may be arranged so as to reflect the condition of a safety-related parameter of the elevator, in a variety of ways. The simplest are shown in Figs. 3 and 4 where the frequency-determining RF loop containing a capacitor 40 and an inductor 41 is either opened by a switch 43 ( Fig. 3 ) or shorted by a switch 44 ( Fig. 4 ). Either of these arrangements will cause the RFID to provide no response at all. On the other hand, the RFIDs can be caused to produce two different responses, one indicative of a safe condition and the other indicative of an unsafe condition, as is illustrated in Fig. 5 . Therein, an additional capacitor 47 is in series with the switch 48, the two being in parallel with the capacitor 40 and the inductor 41.
  • the capacitor 47 When the condition is safe, the capacitor 47 is in the circuit, causing the RFID to be responsive at a first frequency. But if the condition becomes unsafe, the switch 48 will become open and the capacitor 47 will no longer be in the circuit; then, the RFID will respond at a different frequency indicative of the unsafe condition. Utilizing a dual response of this type will allow the controller to identify the particular RFID which has sensed an unsafe condition, in contrast with the prior art, serial-switch safety chain which provided no indication of which of the switches has become open and thus no indication of the nature of the failure. In the embodiments of Figs. 3-5 , the switch must be disposed to react to the condition being monitored, and the RFID should be located immediately adjacent thereto, the switch and wiring being accommodated in the frequency-determining loop.
  • Fig. 7 An alternative form of response is illustrated in Fig. 7 .
  • the capacitor 40 and inductor 41 may indicate one condition when the RFID is adjacent to a structure 51 having magnetic reluctance as indicated in Fig. 6 , but will have a different frequency when there is no adjacent magnetic reluctance, as illustrated in Fig. 7 .
  • This may be utilized either to sense the presence of magnetic reluctance 51 as being the safe condition, or to sense the presence of the magnetic reluctance 51 as being the unsafe condition.
  • the first of these is illustrated with respect to a hoistway door switch, a portion of which is shown in Fig. 8 .
  • the lock selvage 53 (the locking lip) is fastened to the header 54 of the doorway.
  • the locking member 55 is disposed on a hoistway door 56.
  • a contact portion 62 (which normally makes a connection between two terminals on the hoistway door lock switch to indicate that the door lock is engaged) will be adjacent to an associated RFID 63 so as to provide tuning of the frequency-determining loop, as illustrated in Fig. 6 , so as to provide a response indicative of safety.
  • the portion 62 is not immediately adjacent the RFID 63, the situation will be as in Fig. 7 and the response will either be non-existent, or indicative of an unsafe condition.
  • Fig. 9 The opposite situation may be obtained as illustrated in Fig. 9 .
  • the lower limit switches 17, 18 are shown as disposed on a frame 66 which is mounted to the rail 67 by brackets 68.
  • the well-known cam 71 is disposed by brackets 72 to the stile 74, which comprises the main vertical frame of the elevator platform, as is known.
  • the cam 71 will be adjacent to the switch 17, causing it to detune the frequency-determining circuitry, as is illustrated in Fig. 6 , and either causing there to be no response from the RFID 17 or, depending upon the protocol being used, a response indicative of the unsafe condition.
  • the call buttons may each have a passenger-actuated button switch incorporated into the RFIDs frequency determining circuitry ( Figs. 3-5 ), or they may each have a passenger-displaced member with reluctance ( Figs. 6 and 7 ).
  • the lights will normally be wired to building power; the RFID may connect the power through a solid state switch in response to a call confirmation signal transmitted to the RFID.
  • the interrogations should be at a repetition frequency, such as 5HZ or 10HZ, sufficient to coincide with button actuation, which may be as short as 200 msec to 500 msec.
