The specific embodiment
With reference to Fig. 1; A kind of elevator wireless transmitting system; Comprise the elevator wireless control terminal 1 that is positioned at the lift car side; Said elevator wireless control terminal 1 is connected with a wireless transceiver and is connected with the monitor terminal that is positioned at the elevator control cabinet side 4 communications through wireless network, comprises that also one is positioned at the TR 2 of elevator, and said TR 2 was connected the wireless network reception and is connected with said monitor terminal 4 from the data of elevator wireless control terminal 1 and through cable network 3.
Fig. 2 is the structural representation of elevator wireless transmitting system embodiment one of the present invention; Embodiment one is single elevator system; TR comprises a wireless transceiver and elevator transmission over radio terminal, and said elevator transmission over radio terminal is connected with said monitor terminal through cable network.For single car; The elevator wireless control terminal can transmit elevator control signal in the lift car 1, from the voice data of lift car 1 internal fixation phone and the video data of lift car 1 camera; TR and with the radio communication of elevator wireless control terminal, adopt the point-to-point transmission mode.
The present invention can also be directed against the elevator with multiple compartments system; With reference to Fig. 3; Embodiment two is an example with two cars; Comprise two elevator wireless control terminals among Fig. 3; Transmit elevator control signal, voice data and video data in lift car 1 and the lift car 2 respectively, to an elevator transmission over radio terminal should be arranged, a plurality of elevator transmission over radio terminal will realize that through cable network data are connected with the monitor terminal that is positioned at the elevator control cabinet side through a router from the data of wireless network to each elevator wireless control terminal respectively.Therefore, to the elevator device of many cars, TR comprises that also one is used for connecting the router of a plurality of elevator transmission over radio terminals and said monitor terminal.For the elevator wireless transmitting system of many cars, the radio communication of TR and elevator wireless control terminal adopts non-point-to-point transmission mode.
Wireless network is preferably WIFI among the present invention, and when being applied to high-rise building construction, transmission distance is far away excessively; During weak output signal; The present invention is provided with TR through the middle part at elevator, and TR is connected with the monitor terminal wire communication, has guaranteed all kinds of reliability of monitoring data transmission.
Further as preferred embodiment; With reference to Fig. 8; Said elevator wireless control terminal comprises a microprocessor; Said microprocessor is connected with switching value input block, switching value output unit, modulation module, demodulation module respectively, and said modulation module is connected with wireless transceiver through coupling module with demodulation module.Preferably, the switching value input block is connected with the expansion I/O module of microprocessor through first photoelectric isolation module, second photoelectric isolation module respectively with the switching value output unit.
Further as preferred embodiment; Said elevator wireless control terminal data packets transmitted is drawn together voice data, video data and elevator control signal; Said voice data is from the landline telephone in the elevator cage, and said video data is from the first-class image capture device of the shooting in the elevator cage.
Further as preferred embodiment, with reference to Fig. 4, said voice data, video data and elevator control signal are combined in wireless transceiver and adopt different transmission modes.Elevator control signal and voice data all adopt energizing signal to start.When the energizing signal of absence of audio data when using landline telephone (do not have the passenger), voice data does not take wireless communication.
With reference to Fig. 5; The bracket signal that the transmission of video data produces when receiving elevator control signal and lift car to be stopped at arbitrary floor is controlled; When the elevator control signal has displacement; The preferential elevator control signal that sends, and suspend transmitting section frame video data, be set in the present embodiment and stop paying out video data 3 frames; When lift car is stopped at arbitrary floor, there is bracket signal, the transmission frequency of setting video data is first frequency value f0; When lift car left arbitrary floor, car was in closed state, and bracket signal disappears, and the transmission frequency of setting video data is second frequency value f1, and said second frequency value f1 is greater than first frequency value f0.The reason that video data transmission frequency values is set like this is: when car was stopped at a certain floor, elevator door was opened basically, and this moment, the requirement to video monitoring in the lift car can reduce, and can reduce the transmission frequency values of video data; When car left a certain floor, car was in closed state, and for having relatively high expectations of video monitoring, and the possibility of elevator control signal displacement this moment is less, so main transmitting video data and voice data, can promote the transmission frequency values of video data.Can reduce the data volume of wireless communication through the video data type of transmission that adopts the differentiation formula, improve the degree of utilization of wireless communication.
Further as preferred embodiment; With reference to Fig. 6, the transmission mode that said elevator control signal adopts displacement to trigger is when the displacement of elevator control signal; The passing time of the Frame of elevator control signal reduces at interval, and progressively increases to the retransmission time interval under the no displacement state.As shown in Figure 6 for example; Under the no displacement state; The Transmission Time Interval that is the Frame of elevator control signal under the stability condition is T0, and when certain elevator control signal displacement, the Frame of elevator control signal sends two frame data frames fast with the time gap of T1; Increase time gap then to T2, T3, increase time gap again and be stabilized in time gap T0 re-transmission elevator control signal.
Further as preferred embodiment, the present invention can detect and safeguards the elevator control signal, with reference to Fig. 7.When detecting certain elevator control signal, can presetting this semaphore is 0 or be 1, perhaps keeps initial value, has made things convenient for detection like this.
More than be that preferable enforcement of the present invention is specified; But the invention is not limited to said embodiment; Those of ordinary skill in the art can also make all equivalent variations or replacement under the prerequisite of spirit of the present invention, distortion that these are equal to or replacement all are included in the application's claim institute restricted portion.
