Embodiment
Embodiment 1
See also Fig. 1, it is the structural representation of elevator wireless operating device of the present invention.Elevator wireless operating device of the present invention comprises a plurality of passive inducing switch 10, a receiving system 20, data/address bus 30 and elevator main controller 40.Receiving system 20 transmits signals to elevator main controller 40 by data/address bus 30.Be radio communication between passive inducing switch 10 and the receiving system 20.This receiving system 20 comprises card reader 22, reception antenna 21 and decoding circuit 23, wherein reception antenna 21 receives the wireless signal that passive inducing switch 10 sends, send card reader 22 to, read the wireless signal of reception, be resent to decoding circuit 23 decodings by card reader 22.Geographically, this passive inducing switch 10 and receiving system 20 are arranged on and make passive inducing switch 10 in the lift car within the range of receiving of receiving system 20.This elevator main controller 40 is arranged in the outer elevator control cabinet of car (figure does not show).
See also Fig. 2, it is the electrical structure schematic diagram of the embodiment 1 of passive inducing switch 10 shown in Figure 1.Each passive inducing switch 10 comprises a button 11, an inductance coil 12 and a non-contact IC card chip 13.This button 11 and inductance coil 12 and 13 series connection of IC-card chip form a loop.This IC-card chip 13 has its unique recognition coding.
Below specify the operation principle of elevator wireless operating device of the present invention:
When receiving system 20 was in running order, its card reader 22 was in the state of scanning always by reception antenna 21.Because this passive inducing switch 10 is within the range of receiving of receiving system 20, the reception antenna 21 of receiving system 20 can send electromagnetic wave signal when scanning mode, then the signal of card reader 22 can make the magnetic flux of inductance coil 12 of passive inducing switch 10 change.When pressing the button 11, inductance coil 12 is connected with the series loop of IC-card chip.The electric current that inductance coil 12 produces charges to IC-card chip 13, makes IC-card chip 13 enter operating state, then by inductance coil 12 unique coding of IC-card chip 13 storages is launched.Reception antenna 21 receives the wireless signal that inductance coil 12 sends simultaneously, and send card reader 22 to, read the wireless signal of reception by card reader 22, be resent to decoding circuit 23 and be converted to corresponding on off state, by data communication bus 30 switch state signal of button 11 is sent to elevator main controller 40 then.
When button 11 is not pressed, inductance coil 12 disconnects with the series loop of IC-card chip 13, and this moment, the IC-card chip 13 was not recharged, and its coding is not launched away, so this passive inducing switch 10 is in disarmed state.
Therefore the unique coding of the IC-card chip 13 of this passive inducing switch 10 and the corresponding relation of its button need to be provided with when mounted at erection stage and uncertain.Promptly enter when state is set at receiving system, press the button 11 of passive inducing switch 10 in regular turn, the coding of the IC-card chip 13 that 23 pairs of decoding circuits receive is corresponding one by one with its button sequence, thereby produces a coding-button correspondence table in decoding circuit 23.
