Detailed description of the invention
With reference to Fig. 1, a kind of wireless transmission system for elevator, comprise the elevator wireless control terminal 1 that is positioned at lift car side, described elevator wireless control terminal 1 is connected with a wireless transceiver and is connected with monitor terminal 4 communications that are positioned at elevator control cabinet side by wireless network, also comprise that one is positioned at the repeater 2 of elevator, described repeater 2 was connected wireless network reception and was connected with described monitor terminal 4 from the data of elevator wireless control terminal 1 and by cable network 3.
Fig. 2 is the structural representation of wireless transmission system for elevator embodiment mono-of the present invention, embodiment mono-is single elevator system, repeater comprises a wireless transceiver and elevator wireless transmission terminal, and described elevator wireless transmission terminal is connected with described monitor terminal by cable network.For single car, elevator wireless control terminal can transmit elevator control signal in lift car 1, from the voice data of lift car 1 interior landline telephone and the video data of lift car 1 camera, repeater and and the radio communication of elevator wireless control terminal, adopt point-to-point transmission mode.
The present invention can also be for elevator with multiple compartments system, with reference to Fig. 3, embodiment bis-is taking two cars as example, Fig. 3 comprises two elevator wireless control terminals, transmit respectively elevator control signal, voice data and video data in lift car 1 and lift car 2, each elevator wireless control terminal is respectively to there being an elevator wireless transmission terminal, and multiple elevator wireless transmission terminals are realized data with the monitor terminal that is positioned at elevator control cabinet side by cable network by a router by the data from wireless network and are connected.Therefore,, for the elevator device of many cars, repeater also comprises that one is used for connecting the router of multiple elevator wireless transmission terminals and described monitor terminal.For the wireless transmission system for elevator of many cars, the radio communication of repeater and elevator wireless control terminal, adopts non-point-to-point transmission mode.
In the present invention, wireless network is preferably WIFI, and in the time being applied to high-rise building building, transmission distance is excessively far away, when weak output signal, the present invention is provided with repeater by the middle part at elevator, and repeater is connected with monitor terminal wire communication, has ensured the reliability of all kinds of monitoring data transmissions.
Be further used as preferred embodiment, with reference to Fig. 8, described elevator wireless control terminal comprises a microprocessor, described microprocessor is connected with respectively switching value input block, switch amount output unit, modulation module, demodulation module, and described modulation module is connected with wireless transceiver by coupling module with demodulation module.Preferably, switching value input block is connected with the expansion I/O module of microprocessor by the first photoelectric isolation module, the second photoelectric isolation module respectively with switch amount output unit.
Be further used as preferred embodiment, the data of described elevator wireless control terminal transmission comprise voice data, video data and elevator control signal, described voice data is from the landline telephone in elevator cage, and described video data is from the first-class image capture device of the shooting in elevator cage.
Be further used as preferred embodiment, with reference to Fig. 4, described voice data, video data and elevator control signal are combined and adopt different transmission modes in wireless transceiver.Elevator control signal and voice data all adopt energizing signal to start.In the time of the energizing signal of absence of audio data (while using landline telephone without passenger), voice data does not take wireless communication.
With reference to Fig. 5, the bracket signal control that the transmission of video data produces while being subject to elevator control signal and lift car to be stopped at arbitrary floor, in the time that elevator control signal has displacement, the preferential elevator control signal that sends, and suspend transmitting portion frame video data, in the present embodiment, be set as stopping paying out video data 3 frames; In the time that lift car is stopped at arbitrary floor, there is bracket signal, the transmission frequency of setting video data is first frequency value f0; In the time that lift car leaves arbitrary floor, car is in closed state, and bracket signal disappears, and the transmission frequency of setting video data is second frequency value f1, and described second frequency value f1 is greater than first frequency value f0.The reason that structured video data transmitting frequency values is set is like this: in the time that car is stopped at a certain floor, elevator door is opened on substantially, now can reduce the requirement of video monitoring in lift car, can reduce the transmission frequency value of video data; In the time that car leaves a certain floor, car is in closed state, and for having relatively high expectations of video monitoring, and the possibility of now elevator control signal displacement is less, and therefore main transmitting video data and voice data can promote the transmission frequency value of video data.Can reduce the data volume of wireless communication by the video data transmitting mode of employing differentiation formula, improve the degree of utilization of wireless communication.
Be further used as preferred embodiment, with reference to Fig. 6, the transmission mode that described elevator control signal adopts displacement to trigger, in the time of the displacement of elevator control signal, the passing time interval of the Frame of elevator control signal reduces, and progressively increases to without the retransmission time interval under displacement state.For example as shown in Figure 6, under displacement state, the Transmission Time Interval that is the Frame of elevator control signal under stability condition is T0, in the time of certain elevator control signal displacement, the Frame of elevator control signal sends two frame data frames fast with the time gap of T1, then increase time gap to T2, T3, then increase time gap and be stabilized in time gap T0 re-transmission elevator control signal.
Be further used as preferred embodiment, the present invention can detect and safeguard elevator control signal, with reference to Fig. 7.When detecting certain elevator control signal, can be 0 or be 1 by preset this semaphore, or keep initial value, facilitate like this detection.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the distortion that these are equal to or replacement are all included in the application's claim limited range.
