DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments. Therefore, the following description and drawings have been simplified appropriately.

[0013] (Embodiment 1) A first embodiment will be described with reference to Fig. 1. Fig. 1 shows a communication device according to the first embodiment. FIG. 2 is a block diagram showing the configuration of the device.

[0014] As shown in FIG. 1, the communication device 100 includes a control unit 1, a DSP 2, a transmission / reception circuit 3, and an antenna. Equipped with Na4.

[0015] The control unit 1 controls each component of the communication device 100. The control unit 1 has a hardware configuration For example, a calculation circuit having a CPU (Central Processing Unit) and a program memory RAM (Random Access Memory) and ROM (Read Only Memory) The control unit 1 may include a storage device having the following components: The data is acquired, and various data are input to the arithmetic circuit in accordance with the program stored in the storage device. The control unit 1 determines whether the forwarding function and the automatic response function are enabled or disabled. Determine whether

[0016] DSP (Digital Signal Processor) 2 is a processor that performs digital signal processing. A control unit 1, a transmission / reception circuit 3, a microphone 5, and a speaker 6 are connected to the SP2. The transmitting / receiving circuit 3 is connected to an antenna 4 .

[0017] The transmission / reception circuit 3 receives data transmitted from another communication device (not shown) via an antenna 4. The other communication device may have the same configuration as the communication device 100, or may have a different configuration. The DSP 2 acquires data received by the transmission / reception circuit 3. The data may be in the form of a packet. The acquired data, text, location, weather, etc. The DSP2 demodulates the acquired data and extracts the packets contained in the data. The DSP 2, the transmission / reception circuit 3, and the antenna 4 decode the character string and supply it to the control unit 1. The control unit 1 functions as a receiving unit and analyzes the supplied packet.

[0018] The control unit 1 assembles packet data. The DSP 2 converts the assembled packet data. The transmission / reception circuit 3 amplifies the signal generated by the DSP 2. The DSP 2, the transmission / reception circuit 3, and the antenna 4 are used as an automatic transfer means. It functions as such.

[0019] The communication device 100 further includes a microphone 5, a speaker 6, a GNSS module 7, Non-volatile memory 8, LAN port 9, display 10, PTT switch 11, operation unit 12, and and RTC 13.

[0020] The microphone 5 picks up the voice uttered by the user of the communication device 100 and converts it into a voice signal. The DSP2 performs processing such as band limiting on this audio signal to generate a modulated wave. The circuit 3 modulates a carrier wave with the modulating wave generated by the DSP 2 and transmits it via the antenna 4. .

[0021] When the DSP2 acquires audio data, it performs D / A conversion and demodulates it. The speaker 6 outputs the audio signal generated by the DSP 2. It emits a sound based on the signal.

[0022] GNSS Module 7 is a Global Navigation Satellite System (GNSS) m: An antenna that receives radio waves from satellites for GNSS (Global Navigation System), and a receiver that receives the GNSS signal output by the antenna. An example of the GNSS is the Global Positioning System (GPS). The GNSS module 7 acquires location information indicating the location of the communication device 100 and supplies it to the control unit 1. When the communication device 100 is fixed in a predetermined position and not movable with the user, In addition, the location information of the communication device 100 may be stored in the non-volatile memory 8 .

[0023] The non-volatile memory 8 is, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory). The non-volatile memory 8 stores, for example, APRS messages and The display 10 may record the forwarding address, etc. It is a good idea to provide a check key.

[0024] The PTT (Push To Talk) switch 11 is used by the user to transmit a voice signal by speaking. When the PTT switch 11 is not pressed, the control unit 1 If the PTT switch 11 is pressed, the communication device 100 is kept in a reception standby state. 0 is kept in the transmission state. The operation unit 12 accepts operation input from the user. The contents of the operation input to be performed include, for example, enabling at least one of the forwarding function and the automatic response function, or The RTC (Real Time Clock) 13 measures the time by , time information is generated. This generated time information may be used as a time stamp. .

[0025] (Example of operation) Next, an operation example of the communication device 100 will be described with reference to FIG. FIG. 1 is a schematic diagram showing an example of an operation of an example of a communication device shown in FIG. A message forwarding function ( Forward function).

[0026] The terminal 100a and the terminal 100b shown in FIG. 2 are examples of the communication device 100 shown in FIG. The terminal 100a is assigned the call sign "AAAAAA-7", and the terminal 100b is assigned the call sign "AAAAAA-7". The call sign was assigned to the 7th BS. Strictly speaking, the call sign is used by radio equipment including radio communication devices. In this example, the number of lines is assigned to the same number of stations, but in this case, we will assume that the number of lines is agreed upon. The terminal 100b is preset so that the message forwarding function is enabled (ON).

[0027] The terminal 100a receives an operation input by a user of the terminal 100a and transmits an APRS message The terminal 100b transmits the APRS message M1 transmitted from the terminal 100a to the terminal 100b. When terminal 100a receives APRS message M2(ACK), terminal 100b transmits APRS message M2(ACK) to terminal 100a. .

[0028] The terminal 100b transmits a forwarding APRS message M4 (forwarding information). M4 contains the transmitted APRS message M1.

[0029] The forwarding APRS message M4 also includes the Internet line connection destination information of the terminal 100b. The Internet line connection destination information may be the transfer information including the remote control information on the terminal 100b side. The control unit of the terminal 100b controls the Internet line connection of the terminal 100b. The terminal 100b is remotely operated from the E-mail terminal 40 based on the destination information. For example, the terminal 100b may have an Internet mail address that can be received by the terminal 100 b. As an example of remote control of the terminal 100b from the E-mail terminal 40, As described later, the QSY function for setting the communication frequency of the terminal 100b using VoIP is implemented. There is a process to do this (see FIG. 7). The terminal 100b also receives a forwarding APRS message M by remote control from the E-mail terminal 40. 4, the response message to the APRS message M1 sent When the APRS message M1 is received via the other communication device, the response message is sent to the other communication device that sent the APRS message M1. This allows the transmission of the APRS message as a response.

[0030] I-GATE20 is assigned the call sign "CCCCCC-1". I-GATE20 is the forwarding AP Upon receiving the APRS message M4, I-GATE 20 forwards the APRS message M4 to APRS server 3. Here, I-GATE20 is used, but you can also use an APRS gateway station other than I-GATE. It's fine.

[0031] Furthermore, the APRS server 30 forwards the APRS message M4 to a predetermined internet mail address. The E-mail terminal 40 forwards the message to this Internet mail address. The E-mail terminal 40 is a personal computer. However, it may be, for example, a tablet, a smartphone, etc.

[0032] The E-mail terminal 40 notifies the user of the terminal 100b of the forwarded APRS message M4. In many cases, the user of the E-mail terminal 40 and the user of the terminal 100b are the same person. In many cases, the E-mail terminal 40 is located in a place where the user of the terminal 100b can operate it. The APRS transmission message M4, i.e. the transmission information, is transmitted to the APRS Since the APRS message M1 includes the contents of the forwarded APRS message M2, the user of the terminal 100b can read the forwarded APRS message M3 from the forwarded APRS message M4. , the contents of the transmitted APRS message M1 can be confirmed.

[0033] The E-mail terminal 40 has an application installed that enables remote control of the terminal 100b. , for example, a response message using a command is sent via the Internet 50 and the modem 60. The E-mail terminal 40 can transmit the e-mail from the user of the terminal 100b. Operation input, for example, clicking on a link in an e-mail is accepted. The last 40 will automatically be set to the call sign and message line number of the other station. Furthermore, the PC application is started with the response message being input.

[0034] If the automatic response message function is enabled, the terminal 100b waits for an automatic response. Replace the automatic response message M3 with the command message until the time has elapsed. The terminal 100b transmits an automatic response message M3 to the terminal 100a.

[0035] From the above, when the terminal 100b receives the transmission APRS message M1, Therefore, the user of the terminal 100b can forward the message M1 to the forwarding destination email address. The user uses the E-mail terminal 40 to read the forwarded APRS message that has been forwarded to the forwarding destination email address. This allows the user of the terminal 100b to immediately check the contents of the If you are far away from terminal 100b and cannot confirm receipt of APRS messages sent from terminal 100b Even if the APRS message is transmitted, the contents of the transmitted APRS message M1 can be immediately confirmed.

[0036] In addition, when the message forwarding function of the terminal 100b is set to be disabled (OFF), The example operation described is not performed.

[0037] (Message forwarding function setting screen) Next, the setting screen for setting the message forwarding function will be described with reference to FIG. Fig. 3 is a diagram showing an example of the setting screen.

[0038] As shown in FIG. 3, the setting screen 110 displays the following options: "APRS Message Forward", "OFF", "ON(E- The setting screen 110 displays "ON (E-mail 1)", "ON (E-mail 2)", "ON (E-mail 3)", etc. 2. FIG. 2 is a diagram showing an example of a display 10 shown in FIG. 1 is a specific example of one of the displays 10. The setting screen 110 is a screen for setting a message forwarding function. The setting screen 110 is used to set the following: "OFF", "ON (E-mail1)", "ON (Email An input to select one of "ON(E-mail2)" and "ON(E-mail3)" is accepted from the user. The setting screen 110 accepts the input "ON (E-mail1)" from the user. It is preferable to have multiple email addresses so that you can switch between them depending on the situation. There are three replies, but more than one is fine.

[0039] (Message reception processing) Next, an example of a message receiving process of the terminal 100b will be described with reference to FIGS. 4A and 4B. 4A and 4B are flowcharts showing the message receiving process.

[0040] A packet is received (step ST11). Then, the DTI (Data Type Identifier) ​​is determined (step ST12).

[0041] If DTI is ":" (step ST12: YES), the received packet is a message packet. Therefore, the destination call sign is determined (step ST13). If the received packet is not a message packet (step ST12: NO), Then, the message receiving process is terminated.

[0042] Next, a string comparison is performed between the destination callsign and your callsign to find a match. The communication device 1 determines whether the call sign of the own station is set to the same as the call sign of the own station (step ST13). It is set to 00.

[0043] If it is determined that the destination call sign and your call sign match (step ST 13: YES), it is determined that the received packet is an APRS message (step S T14). If the destination call sign and your call sign do not match (step ST13 :NO), the received packet is not a message addressed to the local station, so the message reception process is terminated. Finish.

[0044] Next, the call sign of the other station is acquired (step ST15). The rule sign portion is extracted from the received packet and stored.

[0045] Next, the message body is extracted from the received packet and stored (step ST16 Then, the line number is extracted from the received packet and stored (step ST17). ). Next, create and send an acknowledgment APRS message M2 (ACK) packet (step Top ST18).

[0046] Next, the message forwarding function is set to ON or OFF. It is determined whether the message transfer function is enabled (step ST19). If so (step ST19: YES), create a message for e-mail (step Step ST20 will be described in detail with reference to the flowcharts shown in FIGS. 5A to 5C. If the message forwarding function is disabled (step ST19: NO), ), and the process moves to a step ST22 for determining whether or not to automatically respond to the message.

[0047] Next, the created e-mail message is sent (step ST21).

[0048] Next, check whether the automatic message response function is enabled (ON) or disabled (OFF). It is determined whether the automatic message response function is enabled (step ST22). If so (step ST22: YES), the automatic response waiting time is monitored (step ST If the automatic response waiting time has elapsed (ST23: YES), the automatic response message is The automatic response waiting time is set to a predetermined time. If the automatic message response function is disabled (step ST2 2: NO), terminate the message receiving process.

[0049] Next, it is determined whether or not a command for a response message has been received (step ST24 If the command for the response message is not received (step ST24: NO), Respond with a predefined message as auto-reply message M3 (step ST25).

[0050] If a command for a response message is received (step ST24: YES), The command message will be replaced with the message that has been set for the automatic response message M. The response is 3 (step ST26).

[0051] (E-mail message creation process) Next, the process of creating an E-mail message will be described with reference to FIGS. 5A to 5C. FIG. 5A is a flowchart showing a process for creating an E-mail message. FIG. 5B is a flowchart showing a process for creating an E-mail message. 1 is a table showing the relationship between each step in the message creation process and the e-mail message. FIG. 5C is a diagram for explaining each character string that constitutes an E-mail message.

[0052] This E-mail message creation process is a detailed example of step ST20 shown in FIG. This is the process of constructing a message for mail.

[0053] Set one character ":" (colon) to start the destination call sign area setting (Step S Next, set the character string "EMAIL" in the destination call sign area (step ST32). The destination call sign area is fixed at 9 characters, so you must enter four characters after "EMAIL". " (space). To start the message body area settings, enter ":" (colon Then, one character is set (step ST33).

[0054] The destination e-mail address is set at the beginning of the message body area (step ST3 4) The destination email address is the one set in the APRS message forwarding function, as shown in Figure 1. In the example shown in FIG. 5B and FIG. 5C, it is “abc@def.com”. Characters are set (step ST35).

[0055] Next, the reply-to E-mail address is set (step ST36). The address is the Internet email address of the terminal 100b, and is shown in FIG. 5B and FIG. 5C. In this example, it is "def@def.com". Then, in the same manner as in step ST35, " (spare Then, one character is set (step ST37).

[0056] Next, the IP address of the terminal 100b is set (step ST38). In the example shown in FIG. 5B and FIG. 5C, the address is “111.222.33.44”. As in the case of 35, one character " " (space) is set (step ST39).

[0057] Next, QSY information is set (step ST40). This QSY information is shown in FIG. 5B and FIG. 5C. In the example shown in FIG. 1, it is "430.000MHz". Then, as in step ST35, First, one character (pace) is set (step ST41).

[0058] Next, the received message is set (step ST42). In the example shown in FIG. 5B and FIG. 5C, the message is "hello!". Similarly, one character " " (space) is set (step ST43).

[0059] Next, the call sign of the other station is set (step ST44). The call sign consists of the character string "de" and the call sign format, as shown in the examples in Figures 5B and 5C. is "de AAAAAA".

[0060] Finally, a line number is set (step ST45). In the example shown in Figures 5B and 5C, it is "{00001".

[0063] Set the response message parameters (step ST51). Use ":" as the delimiter. A colon is set as one character (step ST52).

[0064] Next, the call sign of the other station is set (step ST53). In the example shown in FIG. 6, it is "AAAAAA". As in step ST52, Then, a single character ":" (colon) is set (step ST54).

[0065] Next, a response message is set (step ST55). The response message shown in FIG. Another example of the response message is "TEST". Contents indicating that the user is away from the terminal 100b at the time the response message is sent Another example of the response message is as follows: This indicates the point at which it will be possible to handle the above.

[0066] Next, a response message line number is set (step ST56). An example of a reply message line number is "{00001".

[0067] The response message can be created by the above steps. It is possible to control sending to an email address of 100b.

[0068] (Processing to implement QSY function using VoIP) Next, referring to Figure 7, the QSY function is performed using VoIP (Voice over Internet Protocol). The process will be described below.

[0069] In addition, the Q code used internationally in wireless communication is the same as the Q code used in the past. QSY is used to change the voice communication frequency. The QSY function in APRS is used to exchange frequency information for the APRS communication protocol. Use the AFRS (Automatic Frequency Reporting System) format included in the protocol. Frequency information is exchanged through this.

[0070] Specify the IP address of the terminal 100b shown in FIG. 2 and send the e-mail from the E-mail terminal 40 to the terminal 100b. Then, a TCP connection is made to the TCP number, and command communication is performed. (Step ST62). The TCP number is, for example, "TCP:6000". Then, the frequency is changed to the QSY frequency (step ST63). Then, a UDP connection is made to the UDP number. (Step ST64). The UDP number is, for example, "UDP:60001". (step ST65), they perform voice communication with each other (transmitting and receiving), and respond with QSY. This causes the user of the terminal 100b to leave the terminal 100b. Even if the terminal 100b is connected to the E-mail terminal 40, the terminal 100b may be used to change the voice communication frequency used by the terminal 100b. It is possible.
