DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information communication system for controlling communication between a plurality of receiving terminals and transmitting / receiving terminals arranged in an internal space of a moving object and their communication partner devices.

[0002]

For example, in a moving body such as an aircraft, various in-flight services are provided to passengers in an in-flight cabin, which is an internal space, by crew members or equipment. As an in-flight service provided by the cabin crew, there is a mobile sales service in which food or drinks such as food and drinks or souvenirs are mounted on carts that can be moved in the cabin and distributed or sold to passengers.

On the other hand, as in-flight services by the equipment, general voice contact information and music are provided as in-flight services from an in-flight PA system or an earphone provided in a passenger seat. In this case, the music is usually provided with a plurality of channels, and various music programs are provided for each channel, and the passenger has a selection knob so that a desired one can be selected and listened to. The configuration is provided.

[0004] In recent years, the demands of passengers have been diversified, and it is demanded that in-flight services also respond to them. In addition, the spread of information devices such as personal computers has been remarkable, and requests for new in-flight services have been coming up.

[0005] For example, among the in-flight services described above, in mobile sales by cart, it is necessary to manage the products mounted on the cart. That is, the inventory amount of commodities in the machine is managed by merchandise management equipment mounted on each cart that sells commodities, using a memory card for each cart.

However, in this method, since information is not exchanged between carts, for example, if a passenger orders an item that is out of stock in a cart that receives the order, another cart does not. Even if there is such a product, it is not possible to confirm this, so the passenger must be told that there is no product, which may give the impression that the service is not good for the passenger.

Further, in this method, the information on the memory card is read by a reader on the ground side and processed until the data is processed.
Since information about what sold well in the aircraft cannot be obtained, there remains a problem that preparation of well-sold products is delayed. Therefore, despite the fact that there is a product that sells well, the airline will be slow to respond to passengers because passengers will have to inform sold out due to delays in preparation, and in-flight sales services will be It may give the impression that it is not good.

Next, as described above, the in-flight service for providing information such as music and movies is generally a system for providing a plurality of types of programs prepared in advance to passengers. Just listen to music by selecting from the programs included, and personally listen to music software that passengers want to listen to, such as music cassette tapes created by themselves or CDs and videos purchased at travel destinations Inability to do so demands a system to address these needs.

Furthermore, with the spread of personal computers and the like, business people and the like sometimes use a personal computer to create materials for transmission to electronic mail even while traveling on an airplane. The data created for the user can be sent as an e-mail only after the user gets off the aircraft, goes to a place where the user can connect to a network such as a telephone line, and connects to the line there. Therefore, if such an e-mail can be transmitted while the user is on an airplane, the value of the e-mail can be increased for the user.

On the other hand, in an aircraft, when digital equipment is used, the equipment itself may be a source of noise to adversely affect the operation of instruments in the in-flight equipment, or may perform various communications by radio signals. However, there is a possibility that the signal for performing communication with the outside and control of the aircraft by the in-flight equipment may be obstructed. Therefore, use of the aircraft is prohibited, particularly when the aircraft is taking off and landing. Therefore, it is necessary to avoid outputting a radio signal for performing various communications in the airplane as much as possible, which is an obstacle to solving the above-mentioned demands and problems.

The present invention has been made in view of the above circumstances, and has as its object to improve the usability of passengers and crew members in the internal space of a moving body such as an aircraft, and to provide various communication processing.

Next, when the passenger / crew management device 2 receives the data from the in-flight management device 4 (A18), it processes the data (A19 in FIG. 20), and creates and transmits a response signal (A20). ). In this case, the passenger / crew management device 2 recognizes the position of the seat of the passenger who has received the call, and selects a cabin crew that is close to the seat of the passenger and can respond. More specifically, the cabin crew responsible for the seat of the passenger is selected and designated.

When the response signal is transmitted from the passenger / crew management device 2, the in-flight management device 4 receives the data (A 21), attaches the ID code of the in-flight repeater 6 to be transmitted, and transmits the data. Create (A22) and perform data transmission (A

Is transmitted to the cabin crew communication device 8 carried by the user. Also, transmission data for notifying that the cabin crew will respond to the calling passenger is created at the same time, and response transmission data is separately created in the in-flight repeater 6 corresponding to the seat of the passenger. Send.

The data transmitted through the optical fiber 7 is transmitted between the in-flight repeaters 6, and the in-flight repeater 6 that has determined that the data includes its own ID code receives the data. (A24), and read the data (A2
5). Then, the in-flight repeater 6 allocates communication to the communication device in its own communication area C by FCM (A26), forms data (A27), and transmits the data (A28).

The cabin crew communication device 8 existing in the communication area C of the in-flight repeater 6 receives the data (A
29), read the FCM (A30), wait for a predetermined time in preparation for transmission (A31), and transmit data in the designated transmission / reception frame (A32). Thereby, the in-flight repeater 6 is connected to the cabin crew communication device 8.
Then, the data of the transmission confirmation confirming that the data corresponding to the call specified by is received is received, and the communication processing is terminated (A33).

On the other hand, when transmission data is transmitted from in-flight repeater 6 corresponding to the seat of the calling passenger, the passenger communication device 10 receives the data (A3
4) Read the FCM (A35), wait for a predetermined time in preparation for transmission (A36), and transmit data in the designated transmission / reception frame (A37). As a result, the in-flight repeater 6 receives from the passenger communication device 10 data for confirming that a reply to the effect of responding to the calling passenger has been received, and ends the communication processing (A).

(4) Description of Product Inventory Confirmation Processing Next, among the commodity management processing in the case where the cabin attendant carries in-flight sales with products and the like loaded on a cart, a procedure for performing inventory confirmation processing is shown in FIG. Or FIG.
This will be described with reference to the sequence diagram of FIG. This is a process in a case where it is confirmed whether or not the ordered item received from the passenger is not left in the cart and is present in another cart, and if it is attempted to secure it.

The cabin crew communication device 10 includes:
In FIG. 21 to FIG. 23, the cabin attendant carrying out mobile sales using the cart on the side where the target product is in short supply is assumed to be the cabin attendant communication device A (requester), What is carried by the cabin attendant who carries out mobile sales using the cart in which the product remains is indicated as the cabin attendant communication device B (request destination). I will explain.

When the cabin attendant operates the cabin attendant communication device A to enter the missing product number by pen input (FIG. 2).
In B1), the cabin attendant communication device A of the requester performs a communication start process to the in-flight repeater 6 and transmits a communication start request signal (B2). When receiving the communication start request signal in the device detection frame, the in-flight repeater 6 (B

When receiving the data from the cabin crew communication device A (B12), the in-flight repeater 6 performs the data processing (B13), and repeats the above-described processing when communication is necessary (B5 to B13). When the communication is completed, the obtained data is stored in the memory (B14).

Next, the on-board repeater 6 creates transmission data to the management device side (B15), and transmits the data to the on-board management device 4 (B16). At this time, if a transmission error occurs, retransmission is performed. Upon receiving the transmitted data (B17), the in-flight management device 4 classifies the data to which device (B18) and transmits the received data to the corresponding product management computer 2 in this case. (B19). At this time, if a transmission error occurs, retransmission is performed.

Upon receiving the data transmitted from the in-flight management device 4 (B20), the product management computer 2 performs the data processing (B21). This is done by searching the inventory status of the insufficiency products inquired from the database and, if inventory remains, creating communication data to secure the products in the cart where the products remain. It performs processing. Thereafter, based on the result of performing the above-described processing, when the stock is left, the product management computer 2 issues a stock securing instruction to the requested cabin attendant communication device B to perform the stock securing communication. And sends the data to the in-flight management device 4 (B22).

When the transmitted data is received (B23), the in-flight management device 4 transmits the data to the in-flight repeater 6 in the communication area where the cabin crew communication device B to be transmitted exists. Is created (B24), and transmitted (B25). When recognizing that the transmission signal is directed to itself, the in-flight repeater 6 receives this (B26) and reads the data (B27).
Next, the in-flight repeater 6 creates an FCM to communicate with the cabin crew communication device B in its own communication area (B28) and forms transmission data (B29),
The data of the stock securing instruction is transmitted (B30).

The cabin attendant communication device B carried by the cabin attendant carrying in-flight sales in the cart holding the target product, which is a shortage product, in stock is transmitted from the in-flight repeater 6. When the data is received, the FCM is read in the same manner as described above, and after waiting for the timing of the transmission / reception slot allocated to itself, the data is received (B31), and this data reception processing is repeatedly executed until all the data to be received is obtained. I do. As a result, the cabin attendant who has received the instruction to secure stock from the product management computer 2 secures the required number of target products remaining in the cart and excludes them from sales to other passengers (B32). .

Next, after the cabin crew secures the above-mentioned inventory, if the stock confirmation input process is performed by pen input of the cabin crew communication device B to notify the confirmation process (B33), the cabin The crew communication device B performs a communication start process and transmits a communication start request signal to the onboard repeater 6 (B34). The in-flight repeater 6 detects the device ID frame and reads out the device ID code (B35, B36), and the FCM for performing subsequent communication.
Is set to create transmission data, and the data is transmitted to the cabin crew communication device B (B37 to B39).

The cabin crew communication device B is connected to the in-flight repeater 6.
When receiving the data transmitted from, the FCM reads the FCM and transmits the data to be transmitted in the designated transmission / reception frame (B40 to B43). The in-flight repeater 6 receives the data transmitted from the cabin crew communication device B, performs the data processing, and stores the data when the communication for transmitting and receiving the necessary data ends (B44, B45). Then, transmission data to the management device is created and transmitted to the on-board management device 4 (B46 to B48).

When the data transmitted from the in-flight repeater 6 is received, the in-flight management device 4 classifies the data and transmits it to the product management computer 2 as data (B49 to B51). The product management computer 2
Upon receipt of this, data processing is performed, the inventory is confirmed via the cabin crew communication device B, the fact that the missing product has been secured is stored in the database, and the cabin crew requesting that the stock has been secured is confirmed. A response signal is created to notify the cabin crew carrying the communication device A for in-flight,
(B52 to B54).

Upon receiving this, the in-flight management device 4 creates and transmits data to the in-flight repeater 6 in the communication area where the corresponding cabin crew communication device A is located (B55).
To B57). When the corresponding in-flight repeater 6 recognizes that the data is transmission data addressed to itself and receives the data, it reads the data, creates an FCM for the cabin crew communication device A, and forms transmission data for a stock keeping notification. (B58-B62).

The cabin crew communication device A includes the in-flight repeater 6
When the data transmitted from is received, F
After reading the CM and waiting for the timing of the transmission / reception slot allocated to itself, the data is received (B6
3) Repeat this data reception process until all data to be received is obtained. As a result, the cabin attendant notified of the stock confirmation from the product management computer 2 verbally informs the passenger who requested the target missing product that the missing product remains in another cart. Then, a series of product inventory confirmation processing ends.

Thus, when there is no product requested by the passenger, the cabin crew operates communication device A for the cabin crew to perform communication on the spot, thereby holding inventory through the product management computer 2. In addition to contacting the cabin attendant communication device B of the shopping cart to secure inventory of the missing product and obtain confirmation as to whether or not the inventory has been secured, the passenger can immediately make a request on the spot. It is possible to recognize whether or not a desired product can be obtained, and to improve the in-flight service.

(7) Description of Emergency Information Communication Processing Next, communication processing performed when information to be transmitted urgently occurs in the aircraft will be described with reference to FIG. This is a process for simultaneously transmitting emergency information to passengers and cabin crew members in the cabin. In addition to transmitting the information to the passengers by in-flight broadcasting, for example, for passengers who are listening to music using headphones 9, The display 47 is also displayed on the display 47 of the communication device 10 for passengers so that a person with hearing impairment can be visually recognized or visually recognized by a hearing-impaired person. When the earphones 34 are worn on the ears, the earphones 34 are intended to be transmitted by voice.

First, when it is necessary to transmit emergency information in the airplane, when emergency information is input by voice to the AV device 1, this is transmitted as a voice signal (E1 in FIG. 27). In this case, the voice signal of the emergency information is internally processed as a digital signal, and is set so as to be transmitted to all the channels from which the voice data was output. (E2). When emergency information is input to the passenger / crew management device 3, the emergency information is similarly converted into digital data internally as emergency information and transmitted to the in-flight management device 4 (E3).

Upon receiving the emergency information data transmitted from the AV device 1 or the passenger / crew management device 3 (E4), the in-flight management device 4 sends a dedicated down-link to all the in-flight repeaters 6 arranged in the flight. Create data to send emergency information using all channels of the link (E
5), which is transmitted (E6). All in-flight repeaters 6
Receives the emergency information data from the in-flight management device 4 (E7), reads out the data (E8), and transmits the emergency information data to all dedicated downlink channels in the communication frame configuration. The FCM is set to form an FCM, data is formed (E9, E10), and transmitted within each communication area (E11).

In the headphone 9 and the passenger communication device 10, when the emergency information transmitted from the in-flight repeater 6 is received in each communication area, the emergency information is converted into voice data, converted into a voice signal, output and output to the passenger. Notify (E12-E1
4) Or, it is displayed on the display 47 (E15 to E17). Although not shown in the figure, emergency information is also transmitted to the cabin attendant communication device 8 in the same manner. When the emergency information is received, the emergency information is displayed on the display 22 or the earphone 34 is attached. If this is the case, the crew will be notified by outputting this as a voice.

As a result, not only emergency information can be broadcast by in-flight broadcasting, but also emergency information can be transmitted to passengers and crew members simultaneously and reliably using this information communication system.

That is, in the first embodiment, the interference between the on-board repeaters 6a and 6b is prevented by the TDMA method. However, in this embodiment, the FDMA (frequency division multi-channel) is used.

FIG. 29 shows the wavelengths used for transmission in the in-flight repeaters 6a and 6b and the in-flight communication devices 8 and 10, respectively. As shown in FIG. 14, the in-flight repeaters 6a and 6b Since a communication area overlaps between the communication areas, it is necessary to transmit a communication frame configuration so that interference does not occur in the overlapping area. Therefore,
In the first embodiment, the interference is prevented by adopting the TDMA system. However, in this embodiment, the in-flight repeater 6a emits an optical signal having the wavelength λ1, and the in-flight repeater 6b transmits the wavelength λ2 (> λ1). ) Is transmitted using an optical signal.

On the other hand, in the cabin crew communication device 8 or the passenger communication device 10 that receives optical signals from the in-flight repeaters 6a and 6b in each of the communication areas Ca and Cb, signals of both wavelengths λ1 and λ2 are received. When signals of both wavelengths are received, their reception intensities are compared to select the stronger wavelength and switch to receive. When the wavelength of the selected reception signal is λ1, transmission is performed. The wavelength at the time is set to λ3 (> λ2), and when the wavelength of the received signal is λ2, the wavelength at the time of transmission is set to λ4 (> λ3).

Also, as in the cabin crew communication device 8,
In the case of performing communication while moving along the passage in the cabin, the in-flight repeater 6 to be communicated with during the communication during communication is used.
Since the communication areas a and 6b also move, the reception strength changes. Therefore, such a cabin crew communication device 8 is provided so as to always check the reception intensity. When the reception wavelength changes during communication, the selected wavelength is switched accordingly and the transmission signal is changed. Are also switched.
When the in-flight repeaters 6a and 6b to be communicated with are switched, a communication request is sent to start a new communication with the switched in-flight repeaters 6a and 6b, and the procedure is performed. Perform communication processing.

In the same manner as described above, in the audio receiving device 36 provided in the headphones 9, the in-board repeater 6a
And 6b can receive optical signals of wavelengths λ1 and λ2, whereby audio data is received and selectively converted to an audio signal in the same manner as in the first embodiment. It can be played.

When communication is performed using different wavelengths as described above, each of the light receiving sections is provided with an optical filter formed of a multilayer film or the like and is selected. λ1 and λ2 or λ3
2 and λ4 can be transmitted simultaneously without interference even if they are transmitted at the same time.
As shown in FIG. 8, between the on-board repeaters 6a and 6b, the transmission of the communication frame configuration can be performed simultaneously.

(Third Embodiment) FIGS. 30 to 32
Shows a third embodiment of the present invention. What differs from the first embodiment is a communication method performed by the onboard repeater 6 for each communication area. That is, in the first embodiment, communication performed between the in-flight repeaters 6a and 6b and the in-flight communication devices 8, 9, and 10 in each communication area uses an optical signal of a single wavelength to transmit data. In contrast to the method of transmitting and receiving as serial data, this embodiment is different in that a method of transmitting and receiving data as parallel data using optical signals of a plurality of wavelengths is employed.

FIG. 31 shows a block diagram of 8 used for parallel data communication.
The wavelengths λ1 to λ8 (the wavelengths are set to be longer at predetermined intervals in order from λ1 to λ8) are shown, and, for example, data of 8 bits is transmitted at a time. In this case, because the configuration in which the parallel data is transmitted in 8 bits is adopted, the same wavelengths λ1 to λ are used for both the onboard repeaters 6a and 6b.
8, the interference occurs between the two in the overlapping communication area. Therefore, as in the first embodiment, the timing is adjusted to transmit the communication frame configuration in a time-division manner as shown in FIG. It has a configuration.

When communication is performed using the eight wavelengths λ1 to λ8, the light emission (transmission) and light reception (reception) of the wavelengths λ1 to λ8 have a small wavelength difference in order to reduce the adverse effects of interference as much as possible. For example, they are arranged as shown in FIG. 32 so as not to be adjacent to each other. That is, the light emitting and receiving unit 71 of the transmitting and receiving circuit unit, in the light emitting unit 71a of the transmitting circuit 62, converts the light source of each wavelength to, for example, λ
1, .lambda.4, .lambda.7, .lambda.2, .lambda.5, .lambda.8, .lambda.3, .lambda.6, so that adjacent wavelengths are set to separate wavelengths. Are arranged in the order of, for example, λ5, λ8, λ3, λ6, λ1, λ4, λ7, λ2.
