  Next, modes for carrying out the present invention (hereinafter, simply referred to as “embodiments”) will be specifically described with reference to the drawings.

  FIG. 1 shows a configuration of wireless communication 0 according to the present embodiment. The wireless communication system 100 is used in, for example, a disaster prevention wireless system such as a municipality, and includes a control station 30 installed in a municipal office and a plurality of mobile stations 20 installed in each base. Note that the wireless communication system 100 is not limited to a disaster prevention wireless system, but can be applied to a business wireless system used in various businesses such as a security service and a vehicle operation service.

  Each mobile station 20 includes a semi-fixed wireless device 2, a remotely controlled device 5, and a FAX device 6. The semi-fixed radio apparatus 2 is usually installed at each site as a stationary type (fixed type), and some components (the portable radio 1 described later in FIG. ) Can be carried separately. Hereinafter, the case where the semi-fixed wireless device 2 is used as a stationary type is referred to as “semi-fixed mode”, and the case where the semi-fixed wireless device 2 is used as a portable wireless device (portable wireless device 1) is referred to as “portable mode”. .

  The control station 30 includes a base station radio device 10, a control station control device 11, and a control station FAX device 12, and transmits a FAX to the mobile station 20. As the FAX to be transmitted, there are an individual FAX to be transmitted individually and a simultaneous FAX to be simultaneously transmitted to all the mobile stations 20.

  Specifically, the data is transmitted from the control station FAX apparatus 12 to the semi-fixed radio apparatus 2 of each mobile station 20 through the control station control apparatus 11 and the base station radio 10 via the antenna. In each mobile station 20, the FAX apparatus 6 receives the FAX from the semi-fixed wireless apparatus 2 through the remote control apparatus 5. The aerial line may be, for example, a private wireless line or a public wireless line such as a 3G line or a 4G line.

  2 and 3 are block diagrams showing the configuration of the mobile station 20. FIG. 2 shows the mobile station 20 in the semi-fixed mode, and FIG. 3 shows the mobile station 20 in the portable mode.

  The semi-fixed wireless device 2 includes a portable wireless device 1 and a fixed-side device 25. The portable wireless device 1 functions as a semi-fixed mode when the portable wireless device 1 is integrally connected to the fixed device 25, and functions as a portable mode when the portable wireless device 1 and the fixed device 25 are separated.

  The fixed-side device 25 includes a main board 21 that functions as a fixed-side control unit, a power supply unit 23, a coaxial connector 3, a semi-fixed-side external antenna 4, and a folder 22. When the portable wireless device 1 is attached to the fixed side device 25 by the folder 22, it is connected to the semi-fixed side external antenna 4 via the coaxial connector 3 and functions as a semi-fixed mode. When the portable wireless device 1 is removed from the folder 22, it functions as a portable mode.

  The main board 21 is composed of a microcomputer or the like, and develops a control program stored in a ROM (Read Only Memory) (not shown) in a RAM (Random Access Memory) (not shown), so that the main board 21 is connected to the portable radio 1. Controls communication and communication with the FAX apparatus 6 via the remote control apparatus 5, and controls the semi-fixed side short-range wireless unit 7. Communication with the portable wireless device 1 is performed via the semi-fixed near field wireless unit 7.

  The semi-fixed side short-range wireless unit 7 performs short-range wireless communication such as Bluetooth (registered trademark), Zigbee (registered trademark), and wireless LAN.

  The power supply unit 23 converts, for example, power acquired from an external commercial power supply into a predetermined standard, for example, converts AC power into DC power, and supplies it to each component of the semi-fixed wireless device 2. The folder 22 is provided with a contact for supplying power to the portable wireless device 1. When the portable wireless device 1 is attached to the folder 22, power is supplied through the contact.

  The portable wireless device 1 includes a main board 41 that functions as a portable side control unit, an RF unit 42, a battery 43, and a portable side short-range wireless unit 8.

  The main board 41 is composed of a microcomputer or the like, and controls communication with the base station radio 10 and communication with the main board 21 by developing a control program stored in a ROM (not shown) in a RAM (not shown). To do. The main board 41 includes a recording area (FAX reception memory) that holds data when a FAX is temporarily received in the portable mode.

  The RF unit 42 communicates with the base station radio 10 via the coaxial connector 3 and the semi-fixed side external antenna 4 as shown in FIG. 2 in the semi-fixed mode, and as shown in FIG. 3 in the portable mode. Communicate with the base station radio 10 via the portable-side external antenna 9.

  The battery 43 supplies the power acquired from the power supply unit 23 to each component of the portable wireless device 1 and charges it for use in the portable mode in the semi-fixed mode.

  The mobile-side near field wireless unit 8 performs near field communication such as Bluetooth (registered trademark) or Zigbee (registered trademark). Note that the semi-fixed near field wireless unit 7 and the portable near field wireless unit 8 perform the same near field communication.

  In the semi-fixed radio apparatus 2 having the above-described configuration, the portable radio device 1 is attached to the folder 22 and can be connected to an external device such as the FAX apparatus 6 through the remote control apparatus 5 in the normal mode, that is, in the semi-fixed mode. Functions as a device. In the semi-fixed mode, the FAX device 6 can communicate, and communicates with the base station radio 10 that is the opposite station through the remote control device 5, the semi-fixed side short-range wireless unit 7, and the portable-side short-range wireless unit 8. . In an emergency, the portable wireless device 1 is removed from the folder 22, and the portable mode is operated to function as a portable wireless device.

  Here, the processing when a simultaneous FAX is received in the semi-fixed mode will be described more specifically. The simultaneous FAX data received from the control station 30, which is the host device, is converted into serial data by the RF unit 42 of the portable wireless device 1 and separated into control data and non-voice data.

  The control data includes the type of communication, control information, and the like, and the main board 21 of the fixed side device 25 determines whether or not it is a simultaneous FAX based on the control data. If it is determined that the fax is a simultaneous fax, the main board 21 issues a command to the remote control device 5 so that other communications can be disconnected and the fax can be preferentially received.

  The non-voice data is transmitted to the semi-fixed side short-range wireless unit 7 via the portable side short-range wireless unit 8 by the main board 41 of the portable wireless device 1. In the fixed side device 25, the semi-fixed side short-range wireless unit 7 outputs the data received from the portable side short-range wireless unit 8 of the portable wireless device 1 to the remote control device 5 as serial data.

  In the remote control device 5, the main board 51 sends the received serial data to the FAX modem 52, and the FAX modem 52 converts the analog data into an analog signal, which is then transmitted to the FAX device 6. Note that the FAX apparatus 6 and the remotely controlled apparatus 5 are not limited to being configured separately, but may be configured as an integrated apparatus.

  When using as the portable mode, the portable wireless device 1 is removed from the folder 22, but the short-distance communication connection between the semi-fixed-side short-range wireless unit 7 and the portable-side short-range wireless unit 8 is not performed regarding the processing at this time. Therefore, communication of the FAX apparatus 6 cannot be executed. That is, simultaneous FAX reception is not possible. In general, simultaneous FAX communication cannot be performed unless a transmission-side FAX (control station FAX device 12) and a reception-side FAX (FAX device 6) are connected to devices. In the present embodiment, the portable wireless device 1 of the semi-fixed wireless device 2 on the receiving side once receives and holds the FAX data, so that the portable wireless device 1 is attached to the fixed device 25 (folder 22). The contents of the simultaneous FAX will not be lost even in the mobile phone mode, that is, in the mobile mode. Details are shown in the following Examples 1-3.

<Example 1>
FIG. 4 is a flowchart showing processing when a simultaneous FAX is received in the portable mode. When the portable wireless device 1 receives the simultaneous FAX (S10), the main board 41 determines whether it is operating in the semi-fixed mode or the portable mode (S12). In addition, as described above, the main board 41 determines whether it is a simultaneous FAX by referring to the control data.

  If it is the semi-fixed mode (Y in S12), the semi-fixed radio apparatus 2 in the operating state in which the portable radio 1 and the fixed side apparatus 25 are integrated receives the simultaneous FAX by the above-described processing (S14).

  If it is the portable mode (N in S12), the main board 41 determines whether or not the free space in the FAX reception memory is a capacity necessary for FAX reception (S16). If it is insufficient (N in S16), the main board 41 of the portable wireless device 1 leaves a reception NG log in a predetermined storage area and notifies the control station 30 that is a higher-level device of the reception NG (S18). ). The control station 30 (control station FAX apparatus 12) that has received the notification of reception NG retransmits the simultaneous FAX after a predetermined time has elapsed.

  When the free space of the FAX reception memory is sufficient (Y in S16), the main board 41 of the portable wireless device 1 performs a simultaneous FAX reception process and holds the received data in the FAX reception memory (S20).

  When the simultaneous FAX reception process ends normally (Y in S24), the main board 41 ends the series of processes. If not completed normally (N in S24), the reception NG log is left in a predetermined storage area, and the reception NG is notified to the control station 30, which is the host device (S26). The control station 30 (control station FAX apparatus 12) that has received the notification of reception NG retransmits the simultaneous FAX after a predetermined time has elapsed. Note that if the process does not end normally, it is assumed that the capacity of the FAX reception memory is insufficient. Therefore, the portable wireless device 1 may notify the control station 30 to reduce the data and retransmit the data when the reason why the normal termination could not be completed at the time of reception NG notification is due to insufficient capacity of the FAX reception memory. Good.

  As described above, when there is a simultaneous FAX, the portable wireless device 1 holds the received FAX data and indirectly receives the simultaneous FAX. Normally, when the portable wireless device 1 used in the semi-fixed mode receives a simultaneous FAX, it acts as a repeater that transmits and receives data directly to the FAX device 6 through the semi-fixed wireless device 2 and the remotely controlled device 5. I played. In the portable mode, when the simultaneous FAX is received, the portable wireless device 1 directly works on the FAX data. Therefore, not only whether the semi-fixed near field wireless unit 7 and the portable near field wireless unit 8 are connected, Reception is possible. The FAX data once held in the portable wireless device 1 is output to the FAX apparatus 6 through the main board 41 and the remote control apparatus 5 when the semi-fixed mode is entered again.

  When the portable wireless device 1 performs reception processing in which the FAX data is stored in the FAX reception memory of the main board 41, the portable radio device 1 notifies the control station 30 (that is, the control station FAX device 12) to that effect. Also good. In this case, the control station 30 may be notified that the FAX apparatus 6 has actually output a FAX after shifting to the semi-fixed mode. As a result, the control station 30 (control station FAX device 12) remains in a state in which the mobile station 20 receives the status of the data faxed at the same time, that is, in the state where the portable radio device 1 has received it. In addition, it is possible to grasp and manage whether the fax apparatus 6 has actually output. When the control station 30 (control station FAX apparatus 12) receives, for example, a notification from the portable wireless device 1 that reception has been completed in the portable mode, that is, a notification that it has been recorded in the FAX reception memory, You may perform the process which resends at intervals rather than resending. In addition, when the period during which the FAX output is not finally performed is long, that is, when the period during which the semi-fixed wireless device 2 does not enter the semi-fixed mode and remains in the portable mode is long, It is also possible to perform a process of notifying the user to shift to the fixed mode and output the fax.

<Example 2>
In the above-described first embodiment, when the FAX reception memory built in the portable wireless device 1 becomes full, it becomes impossible to newly receive a simultaneous FAX. In order to solve this, in this embodiment, when receiving the reception NG notification of FIG. 4 (S18, S20), the control station 30 retransmits the simultaneous FAX to the semi-fixed radio apparatus 2 under a predetermined condition. . FIG. 5 is a chart diagram of processing for retransmitting a simultaneous FAX to the semi-fixed radio apparatus 2.

  When the portable wireless device 1 operating in the portable mode fails to receive the simultaneous FAX, the portable radio device 1 notifies the control station 30 to that effect (reception NG) (S101). The control station FAX apparatus 12 of the control station 30 records the received NG in the transmission history and retains the simultaneous FAX data without discarding it.

  When the portable wireless device 1 is attached to the folder 22 and enters the semi-fixed mode, the main board 21 of the fixed-side device 25 notifies the main board 41 of the portable wireless device 1 that it is attached to the folder 22. (S102). The main board 41 of the portable wireless device 1 notifies the control station 30 that it has shifted to the semi-fixed mode (S103).

  In the control station 30 that has received the notification, the control station FAX device 12 retransmits the simultaneous FAX data to the mobile station 20 that is the notification source. That is, the FAX is transmitted from the control station FAX device 12 of the control station 30 to the portable radio device 1 of the semi-fixed radio device 2 through the control station control device 11 and the base station radio device 10 (S104).

  The RF unit 42 of the portable wireless device 1 converts the received data into serial data and separates it into control data and non-voice data, and the main board 41 sends the non-voice data to the main board 21 of the fixed side device 25. Transmission is performed by short-range communication between the fixed-side short-range wireless unit 7 and the portable-side short-range wireless unit 8 (S105). In other words, the portable wireless device 1 transmits a fax to the fixed device 25.

  In the fixed apparatus 25, the main board 21 performs FAX transmission to the remote control apparatus 5 (S106). At this time, it is desirable that the fixed-side device 25 instructs the remote control device 5 to give priority to the reception of the simultaneous FAX as in the case of the normal simultaneous FAX. That is, since the FAX data retransmitted from the control station 30 is not strictly a simultaneous FAX, it may be assumed that the control data does not include information indicating that it is a simultaneous FAX. Therefore, in such a case, the main board 21 instructs the remote control device 5 to give priority to the reception of the FAX if it is a simultaneous FAX retransmission compared to the log at the time of reception NG. To do.

  The remote control device 5 transmits the FAX acquired from the fixed side device 25 to the FAX device 6 (S107). That is, the remote control device 5 converts the non-voice data acquired from the fixed side device 25 into analog data and sends it to the FAX device 6.

  When the reception of the retransmitted simultaneous FAX is completed, the FAX apparatus 6 notifies the remote control apparatus 5 of the completion of reception (S108). The reception completion notification is fixed by communication between the semi-fixed-side short-range wireless unit 7 and the portable-side short-range wireless unit 8 from the remote control device 5 to the fixed-side device 25 (S109) by the same processing as that for normal simultaneous FAX. Transmission from the main board 21 of the side device 25 to the main board 41 of the portable wireless device 1 (S110), and further transmission from the RF unit 42 of the portable wireless device 1 to the control station 30 (that is, the control station FAX device 12) of the host device. (S111). Note that the reception completion notification may include information capable of determining that the reception of the retransmitted simultaneous FAX is completed as well as the reception completion.

  By such processing, even when reception is not possible at normal simultaneous FAX timing, transmission to the FAX apparatus 6 of the mobile station 20 can be surely completed.

<Example 3>
In the above-described second embodiment, simultaneous FAX retransmission is not performed unless the mode is shifted to the semi-fixed mode. However, in this embodiment, the short-range wireless communication (semi-fixed-side short-range wireless unit 7) is in operation even in the portable mode. And communication with the portable-side short-range wireless unit 8) will be described. FIG. 6 is a chart of processing for retransmitting a simultaneous FAX to the semi-fixed radio apparatus 2, and is a modification of the processing in FIG. Here, processing different from the processing shown in FIG. 5 will be mainly described with different reference numerals attached.

  When the portable wireless device 1 operating in the portable mode fails to receive the simultaneous FAX, the portable radio device 1 notifies the control station 30 to that effect (reception NG) (S101).

  When the main board 21 of the fixed-side device 25 can communicate by short-range wireless communication between the portable wireless device 1 operating in the portable mode, the semi-fixed-side short-range wireless unit 7 and the portable-side short-range wireless unit 8, This is notified to the portable radio device 1 (S102A). The main board 41 of the portable wireless device 1 that has received the notification notifies the control station 30 that it can communicate, that is, that it can receive a FAX (S103A).

  Upon receiving the notification, the control station 30 transmits a FAX from the control station FAX device 12 to the portable wireless device 1 of the semi-fixed wireless device 2 through the control station control device 11 and the base station wireless device 10 (S104). .

  The RF unit 42 of the portable wireless device 1 converts the received data into serial data and separates it into control data and non-voice data. The main board 41 transfers the non-voice data to the main board 21 of the semi-fixed radio device 2. Transmission is performed by short-range communication between the semi-fixed side short-range wireless unit 7 and the mobile-side short-range wireless unit 8 (S105A). In other words, the portable wireless device 1 performs FAX transmission to the semi-fixed wireless device 2 while maintaining the operation state of the portable mode.

  In the fixed apparatus 25, the main board 21 performs FAX transmission to the remote control apparatus 5 (S106). The remotely controlled device 5 transmits the FAX acquired from the semi-fixed wireless device 2 to the FAX device 6 (S107).

  When the reception of the retransmitted simultaneous FAX is completed, the FAX apparatus 6 notifies the remote control apparatus 5 of the completion of reception (S108). The reception completion notification is sent from the remote control device 5 to the semi-fixed wireless device 2 (S109) by the same processing as that for normal simultaneous FAX, through communication between the semi-fixed near field wireless unit 7 and the portable near field wireless unit 8 From the main board 21 of the fixed-side device 25 to the main board 41 of the portable wireless device 1 (S110A), and further from the RF unit 42 of the portable wireless device 1 to the control station 30 (that is, the control station FAX device 12) of the host device. It is transmitted (S111A). Note that the reception completion notification is not only for the completion of reception but also for data transmission between the semi-fixed wireless device 2 and the fixed-side device 25 by short-range wireless communication in the mobile mode instead of the semi-fixed mode. Information that can be determined may be included.

  According to the wireless communication system 100 of the above embodiment, since the semi-fixed wireless device 2 can reliably receive the simultaneous FAX in either the semi-fixed mode or the portable mode, it can be surely notified to the receiver.

  Note that simultaneous faxes are reliably received in the above processing because the simultaneous faxes are highly important, but naturally the same processing can be applied to transmission / reception of normal faxes that are not simultaneous faxes. That is, for example, when it is determined that the FAX transmission is performed from the control data during the portable mode, the main board 41 of the portable wireless device 1 holds the received data in the FAX reception memory and outputs it to the FAX apparatus 6 after shifting to the fixed mode. It is also possible to notify the control station 30 that fax reception is not possible.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of these components, and such modifications are also within the scope of the present invention.

  For example, in the above embodiment, transmission / reception of simultaneous FAX or normal FAX has been described, but the present invention is not limited to this. A modification applied to data transmission other than FAX will be described with reference to FIGS. The same components as those in the above embodiment are denoted by the same reference numerals and description thereof will be omitted as appropriate.

  FIG. 7 shows a configuration of a radio communication system 100a according to a modification. The wireless communication system 100a includes a control station 30a and a mobile station 20a.

  The control station 30a includes a base station radio 10, a control station control device 11, and a control station data transmission device 12a. The control station data transmitter 12a outputs data in a predetermined format. The output data is output to the mobile station 20a via the control station control device 11 and the base station radio 10 described above. The data in a predetermined format is, for example, map data, image data (moving image data or still image data), or data in a format that can be used by a predetermined application.

  The mobile station 20a has a plurality of types of device configurations. A certain type of mobile station 20a includes a semi-fixed wireless device 2, a remotely controlled device 5, and an external device 6a. That is, the FAX apparatus 6 of the above embodiment is replaced with the external apparatus 6a. The external device 6a can display data in a predetermined format transmitted from the control station 30 (control station data transmission device 12a) or execute it with a predetermined application.

  Another type of mobile station 20a is a semi-fixed radio apparatus 2a with an output function in which the functions of the semi-fixed radio apparatus 2, the remote control apparatus 5 and the external apparatus 6a are integrated.

  FIG. 8 shows the configuration of the semi-fixed radio apparatus 2a with an output function. Here, the state of the semi-fixed mode is shown. The semi-fixed radio apparatus 2a with an output function has a configuration in which a data output processing unit 26 is added to the semi-fixed radio apparatus 2 of FIG.

  The data output processing unit 26 includes a display unit 27, a printing unit 28, and an application execution unit 29. The data output processing unit 26 executes each function using data output from the control station data transmission device 12a.

  Specifically, the display unit 27 includes a display panel and its control device, and displays image data, for example.
