In order to understand the utility model more clearly, set forth the utility model specific embodiment below with reference to description of drawings.
Description of drawings
Fig. 1 is the structural representation of the utility model elevator wireless type operating control.
Fig. 2 is the electrical structure scheme drawing of the embodiment 1 of passive inducing switch shown in Figure 1.
Fig. 3 is the electrical structure scheme drawing of the embodiment 2 of passive inducing switch shown in Figure 1.
The specific embodiment
See also Fig. 1, it is the structural representation of the utility model elevator wireless operating device.Elevator wireless operating device of the present utility model comprises a plurality of passive inducing switch 10, a receiving device 20, data bus 30 and elevator main controller 40.Receiving device 20 transmits signals to elevator main controller 40 by data bus 30.Be radio communication between passive inducing switch 10 and the receiving device 20.This receiving device 20 comprises card reader 22, card reader antenna 21 and decoding scheme 23, wherein card reader 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 scheme 23 decodings by card reader 22.Geographically, this passive inducing switch 10 and receiving device 20 are arranged on and make passive inducing switch 10 in the lift car within the range of receiving of receiving device 20.This elevator primary 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 scheme drawing 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 principle of work of the utility model elevator wireless operating device:
When receiving device 20 was in running order, its card reader 22 was in the state of scanning always by card reader antenna 21.Because this passive inducing switch 10 is within the range of receiving of receiving device 20, the card reader antenna 21 of receiving device 20 can be sent electromagnetic wave signal when scanning mode, then the signal of card reader 22 can make the magnetic flow 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 mode of operation, then by inductance coil 12 unique coding of IC-card chip 13 storages is launched.Card reader 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 scheme 23 and be converted to cooresponding 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 installation phase and uncertain.Promptly enter when state is set at receiving device, 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 schemes receive is corresponding one by one with its button sequence, thereby produces a coding one button corresponding tables in decoding scheme 23.
Embodiment 2
