DETAILED DESCRIPTION OF THE INVENTION

[0012] Specific embodiments to which the present invention is applied will be described in detail below 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 as appropriate.

[0013] (Embodiment 1) The 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. The SP2 is connected to a control unit 1, a transmitting / receiving circuit 3, a microphone 5, and a speaker 6. 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 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 packets.

[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 act 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 the 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 GNSS satellites and a receiver that receives the GNSS signals 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 not movable with the user but is fixed in a predetermined position, The location information of the communication device 100 may be stored in the non-volatile memory 8 .

[0023] The nonvolatile 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 have a check key.

[0024] The PTT (Push To Talk) switch 11 is operated 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 10 0 is kept in a transmitting state. The operation unit 12 accepts an operation input from the user. The contents of the operation input to be performed may include, for example, enabling at least one of a forwarding function and an automatic answering function, or The RTC (Real Time Clock) 13 measures the time , time information is generated. This generated time information may be used as a time stamp. .

[0025] (Example of operation) Next, an example of the operation of the communication device 100 will be described with reference to FIG. 1 is a schematic diagram illustrating 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". Strictly speaking, the call sign is used by radio equipment including communication devices. In this example, the following is assumed to be an agreement. The terminal 100b is set in advance to enable (ON) the message forwarding function.

[0027] The terminal 100a receives an operation input from the user of the terminal 100a and transmits an APRS message M1 to the terminal 100b. The terminal 100b receives the APRS message M 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 transferred by the remote control of the terminal 100b. The control unit of the terminal 100b controls the internet line connection of the terminal 100b. The terminal 100b receives remote control from the E-mail terminal 40 set based on the destination information. For example, the terminal 100b can receive an internet mail address, b. An example of remote control of the terminal 100b from the E-mail terminal 40 is As will be described later, the QSY function for setting the communication frequency of the terminal 100b using VoIP is implemented. There is a process (see Figure 7) for this. Furthermore, the terminal 100b receives a forwarding APRS message M by remote control from the E-mail terminal 40. 4, the response message to the transmitted APRS message M1 is sent to the If 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 reply.

[0030] I-GATE20 has been 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 it is also possible to 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 also be, for example, a tablet, a smartphone, etc.

[0032] The email 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 message M4, i.e., the transmission information, is transmitted to the APRS message Since the contents of the forwarded APRS message M1 are included, the user of the terminal 100b can read the contents of the forwarded APRS message M4 from the , the contents of the transmitted APRS message M1 can be confirmed.

[0033] The email terminal 40 has installed thereon an application that allows remote control of the terminal 100b. , for example, by sending a response message using a command via the Internet 50 and modem 60 The E-mail terminal 40 can send the E-mail from the user of the terminal 100b. It accepts input such as clicking on a link in an email. The end 40 will automatically set the call sign and message line number of the other station. Furthermore, the PC application is started up 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 transmitted 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 email 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 the APRS message sent from terminal 100b Even if the APRS message M1 is transmitted, the contents of the transmitted APRS message M1 can be immediately confirmed.

[0036] If the message forwarding function is disabled (OFF), the terminal 100b 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 explained with reference to Figure 3. 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-mail1)", "ON(E-mail2)", "ON(E-mail3)", etc. 2. The display 10 shown in FIG. The setting screen 110 is a specific example of the display 10. The setting screen 110 is a screen for setting the message forwarding function. The setting screen 110 is used to set "OFF", "ON (E-mail1)", "ON (E-mail2)", "ON (E-mail3)", "ON (E-mail4)", "ON (E-mail5)", "ON (E-mail6)", "ON (E-mail7)", "ON (E-mail8)", "ON (E-mail9)", "ON (E-mail10)", "ON (E-mail11)", "ON (E-mail12)", "ON The system accepts an input from the user to select either "ON(E-mail2)" or "ON(E-mail3)". 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 would be good.

[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 not (step ST12: NO), the received packet is not a message packet. Then, the message reception process is terminated.

[0042] Next, a string comparison is performed between the destination call sign and your own call sign to determine if they match. The communication device 1 determines whether or not the call sign of the own station is It is set to 00.

[0043] If it is determined that the destination call sign and your own call sign match (step ST 13: YES), the received packet is determined to be an APRS message (step S T14). If the destination call sign and your station call sign do not match (step ST13 :NO), the above received packet is not a message addressed to the local station, so the message reception process is 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 Next, the line number is extracted from the received packet and stored (step ST17 ). Next, create and send a packet for the APRS message M2 (ACK) acknowledging receipt (step (Up ST18).

[0046] Next, the message forwarding function (Forward function) is set to enabled (ON) or disabled (OFF). It is determined whether the message transfer function is enabled (step ST19). If so (step ST19: YES), create an email message (step Step ST20 will be described in detail with reference to the flowcharts shown in FIGS. 5A to 5C. If the message transfer function is disabled (step ST19: NO), ), and then the process moves to the determination of an automatic message response (step ST22).

[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 the answer is YES (step ST22), the automatic response waiting time is monitored (step ST If the automatic response waiting time has elapsed (ST23: YES), the automatic response message The automatic response waiting time is set to a predetermined time. If the automatic message response function is disabled (step ST2 2: NO), the message reception process ends.

[0049] Next, it is determined whether or not a command for a response message has been received (step ST24 If a command for a response message is not received (step ST24: NO), Respond with a pre-defined message as automatic 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 up for the automatic reply 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 the process of creating an 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. 4B. This is the process of assembling a message for mail.

[0053] Set one character ":" (colon) to start the destination call sign area setting (Step S Next, enter 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 " " (space). To start the message body area, enter ":" (colon). Then, one character is set (step ST33).

[0054] The email address of the recipient 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 transfer function, and is shown in Figure 1. In the example shown in Figures 5B and 5C, it is "abc@def.com". Characters are set (step ST35).

[0055] Next, the reply destination email address is set (step ST36). The address is the internet mail address of the terminal 100b, and is shown in FIGS. 5B and 5C. In this example, it is "def@def.com". Then, as in step ST35, " (special 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 FIGS. 5B and 5C, the address is "111.222.33.44". As in 35, one character " " (space) is set (step ST39).

[0057] Next, QSY information is set (step ST40). This QSY information is shown in FIGS. 5B and 5C. In the example shown in FIG. 1, it is "430.000MHz". Then, as in step ST35, A 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 a character string indicating "de" and the call sign format, and in the examples shown 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".

[0061] (Response message command creation process) Next, the response message command creation process will be described with reference to Fig. 6. 10 is a flowchart showing a response message command creation process.
