the passengers in the same waiting area have the same information content obtained through the sound wave radiation of the sound transmission mechanism 20; the information content acquired by the acoustic radiation of the acoustic transmission mechanism 20 by the passengers located in the same guide area 306 is the same.
In some preferred embodiments, the waiting platform further comprises a ceiling 303, the ceiling 303 is supported by the mounting frame 10, sound absorbing cotton is paved on one side of the ceiling 303 close to the diversion platform 301, a sound absorbing board is installed on the sound absorbing cotton, and a plurality of sound absorbing holes are formed in the sound absorbing board in a penetrating mode.
In this alternative embodiment, by providing a sound absorbing structure in the ceiling 303, the influence of the sound wave radiated from the sound transmitting mechanism on the space above the platform after being reflected by the diversion platform (ground) can be effectively reduced.
In some examples, the ceiling 303 is connected to the mounting frame 10 by bolting;
in other examples, the mounting frame 10 and the ceiling 303 are integrally formed by an integral molding process (e.g., an integral die casting process).
In some examples, the sound absorbing cotton includes any one or combination of fiberglass soundproofing cotton, gradient cotton, and non-woven fabrics.
In some alternative embodiments, a photovoltaic power generation set 305 is disposed on the ceiling 303, and the photovoltaic power generation module 305 is electrically connected to the directional microphone device.
In some preferred embodiments, the directional microphone device comprises a wireless communication module, wherein the wireless communication module is arranged on the vehicle entering side of the waiting platform and is used for acquiring the bus dynamic information of a parked bus in a wireless communication mode and controlling the microphone mechanism 20 to radiate sound related to the bus dynamic information to passengers in the waiting platform through the control system.
In some examples, the bus dynamic information includes, but is not limited to, an ID code of the bus, route information, current location information, bus arrival condition information, time information, and the like.
In some examples, the wireless communication module is NFC.
In this embodiment, an example of a multi-waiting area integration scenario using the aforementioned waiting platform is further provided, referring to fig. 8-10, a passenger enters the diversion channel through the entry 307, then enters the waiting area through the diversion channel and the diversion port 304 (i.e. the junction between the diversion channel and the waiting area) in sequence, and gets on the bus through the boarding aisle after the bus is stopped at the parking space 308. Due to the arrangement of the directional microphone, the radiated sound waves only propagate to the corresponding waiting areas or guiding areas 306, and the crosstalk problem can be avoided to the greatest extent between the waiting areas/guiding areas.
It should be noted that, for the sound transmission mechanism 20 at each waiting area, the sound transmission mechanism 20 taking the waiting area as the preset area and the sound transmission mechanism 20 taking the diversion area as the preset area may be identical or different in content;
Those skilled in the art will appreciate that the sound transmission mechanisms at different shunt ports on the same side of the shunt channel may play different or the same content. Illustratively, the speaking mechanisms 20 at the different shunt ports play different items in order to guide the passenger into their waiting area of interest.
The display mechanisms 30 on the two sides of the shunt channel can display the same or different contents; for the display mechanism 30 near the waiting area and the display mechanism 30 opposite to the display mechanism (i.e., the display mechanism 30 near the side of the diversion channel), the contents displayed by the two display mechanisms may be identical or different.
In a specific implementation process, waiting platforms 302 are distributed on two sides of the diversion platform 301, and two sets of sound transmission mechanisms 20 opposite to each other are arranged on each set of mounting frames 10; wherein, the contents played by the sound transmission mechanisms 20 near the two sides of the diversion station 301 include bus shift information and bus route information; the content played by the speaking mechanism 20 near the waiting stand 302 (i.e., the speaking mechanism 20 opposite the side of the diversion tunnel) includes bus departure time information and bus arrival time information.
It will be appreciated that the alternatives in embodiment 1 described above are equally applicable to this embodiment and will not be repeated here.
Example 4
The method for guiding the waiting passenger, which is applied to the waiting platform proposed in embodiment 3, referring to fig. 11, includes:
when detecting that a passenger enters a guiding area, the control system sends an instruction to a corresponding sound transmission mechanism 20, so that the sound transmission mechanism 20 plays bus shift information related to a corresponding waiting area towards the corresponding guiding area;
If the bus shift information meets the requirements of the passengers, the passengers can enter the corresponding waiting areas through the split ports, the bus shift information does not meet the requirements of the passengers, and the passengers move to the next guiding area;
when a passenger enters a preset waiting area, the sound transmission mechanism 20 plays corresponding bus dynamic information towards the corresponding waiting area.
In some preferred embodiments, the bus dynamic information includes, but is not limited to, vehicle real-time location information, departure time information, and/or arrival time information.
