  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Here, a radio transmitter capable of transmitting a radio signal by changing an operation frequency serving as a transmission frequency within a preset operating frequency band will be described. FIG. 1 shows a configuration example of a wireless transmitter 100 according to an embodiment of the present invention. As shown in FIG. 1, the wireless transmitter 100 includes a control unit 110, a wireless communication unit 120, an antenna 121, an input unit 130, an output unit 140, and a storage unit 150. .

  The control unit 110 is configured using, for example, a microcomputer including a CPU (Central Processing Unit), controls each unit of the wireless transmitter 100, and is stored in a predetermined unit stored in the storage unit 150. Each process to be described later is executed based on the operation program. As an example, the CPU provided in the control unit 110 includes a fixed data read operation for reading fixed data from a ROM (Read Only Memory) provided in the storage unit 150, a RAM (Random Access Memory) provided in the storage unit 150, and the like. A fluctuation data writing operation for writing various fluctuation data in the memory and temporarily storing it, a fluctuation data reading operation for reading various fluctuation data temporarily stored in the RAM, etc., and a signal input for accepting input of various signals from the outside of the control unit 110 Operation and signal output operation for outputting various signals to the outside of the control unit 110 may be executed.

  The wireless communication unit 120 is configured using various signal processing circuits such as an amplifier, a tuner, and a filter, and transmits a wireless signal via the antenna 121. The wireless communication unit 120 can transmit a wireless signal by changing an operation frequency that is a transmission frequency within a preset operating frequency band based on, for example, a design specification of the wireless transmitter 100.

  The input unit 130 includes various switches such as a push switch that forms an operation key and a dial switch that forms an operation dial, a touch panel, a keyboard, a mouse, or a part or all of these, and an input operation by a user And the like, and functions as an input interface for inputting various setting information, operation instructions, and the like to the wireless transmitter 100. The input unit 130 is not limited to inputting information and instructions by a user's operation, for example, a cable connector for receiving setting information transmitted by cable connection with an information processing device such as an external computer, Alternatively, it may include a network interface or the like for receiving setting information distributed from an information processing apparatus such as a server by connecting to a telecommunication network such as the Internet or a LAN (Local Area Network).

  The output unit 140 includes, for example, an image display device such as a liquid crystal display device, an audio output device such as a speaker, a light emitting device such as a lamp or an LED (Light Emitting Diode), or a part or all of these, and is provided to the user. It functions as an output interface for performing various information outputs and operation notifications.

  The storage unit 150 includes, for example, a semiconductor memory such as a RAM, a ROM, and a flash memory, a magnetic disk storage device such as an HDD (Hard Disk Drive), an optical disk storage device such as a CDROM and a DVD, or a part or all of these. In addition to the operation program executed by the control unit 110, data necessary for executing each process, data generated by executing each process, and the like are stored. Note that a part or all of the storage unit 150 may be built in a microcomputer constituting the control unit 110 or may be externally attached. Further, a part or all of the storage unit 150 may be fixed and installed inside the wireless transmitter 100, or may be installed detachably.

  The operation program stored in the storage unit 150 may include an arbitrary basic program that governs the basic operation of the entire wireless transmitter 100. In addition, the operation program only needs to include software for executing each process to be described later by the control unit 110 or the like to realize each function. The control unit 110 functions as a configuration as shown in FIG. 1 by reading and executing the operation program stored in the storage unit 150. That is, the control unit 110 has a function of operating as a frequency section setting processing unit 111, a transmission operation control unit 112, a frequency change determination processing unit 113, and a change determination time operation control unit 114. The functional configuration of these control units 110 may be logically realized by software. For example, hardware such as ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array) is used. These functional configurations may be physically realized by a device.

  The frequency partition setting processing unit 111 divides the operating frequency band into a plurality of frequency partitions by setting an edge frequency that is a boundary frequency within a preset operating frequency band corresponding to the wireless communication unit 120. It functions as a boundary frequency setting means for executing processing for performing the above. Here, as the plurality of frequency sections, for example, based on input information from the input unit 130, a transmission prohibition section that prohibits transmission of radio signals and a transmittable section that enables transmission of radio signals are set. be able to. Further, when setting the edge frequency, for example, based on input information from the input unit 130 or the like, depending on which of a plurality of types of radio wave formats that can be used in advance as a signal format of a radio signal is available. Different edge frequencies can be set.

  When a plurality of frequency partitions are set by the frequency partition setting processing unit 111, data indicating the setting contents is provided in advance in a predetermined area of the storage unit 150 (for example, a rewritable storage device such as a RAM or a flash memory). It may be stored in a user area or the like. That is, the storage unit 150 has a function as a setting data storage unit that stores data indicating the setting content of the edge frequency serving as the boundary frequency.

  The transmission operation control unit 112 functions as a transmission operation control unit that executes processing for controlling the transmission operation of the wireless signal by the wireless communication unit 120 by outputting various control signals to the wireless communication unit 120. Here, as radio signal transmission operation control, for example, a radio wave signal format is selected and set from a plurality of types such as CW mode (telephone), telephone mode, image mode, and narrowband digital mode. The carrier wave modulation method is selected from a plurality of types such as DSB (Double Side Band), SSB (Single Side Band Modulation), and FM (Frequency Modulation). Setting, adjusting the transmission frequency of the radio signal to be changeable, adjusting the output power of the radio signal to be changeable, and the like. As described above, the transmission operation control unit 112 includes a function as signal format setting means for setting the radio wave format to one of a plurality of types. Note that the change width (frequency step) when changing the transmission frequency of the radio signal may be a plurality of types (for example, 0.1 kHz / 1 kHz, for example, depending on the user operation on the input unit 130 or the initial setting in the radio transmitter 100). / 5 kHz / 9 kHz / 10 kHz / 12.5 kHz / 20 kHz / 25 kHz, etc.), or may be a predetermined inherent unit.

  For example, the frequency change determination processing unit 113 determines whether or not the transmission frequency of the radio signal has been changed, and determines whether or not the transmission frequency has been changed across the edge frequency that becomes the boundary frequency when the transmission frequency is changed. It functions as a frequency change determination means for executing processing for making various determinations related to the change of the transmission frequency. Here, as a case where the transmission frequency is changed across the edge frequency, from the high frequency side of the edge frequency, when changing to the low frequency side beyond the edge frequency, from the low frequency side of the edge frequency, In some cases, the frequency is changed to the high frequency side beyond the edge frequency. The transmission frequency thus changed across the edge frequency may shift from the transmission prohibited section to the transmittable section, or may shift from the transmittable section to the transmission prohibited section among the plurality of frequency sections. . The frequency change determination processing unit 113 can transmit the transmission frequency from the transmission prohibited section when the transmission frequency is changed across the edge frequency based on the setting content by the frequency section setting processing unit 111 and the like. It is determined so that it can be specified between a first frequency changing operation for shifting to a section and a second frequency changing operation for shifting the transmission frequency from the transmittable section to the transmission prohibited section.

  The change determination operation control unit 114 performs processing for changing determination operation control by executing processing for controlling predetermined operations as various preset operations when the transmission frequency is changed across the edge frequency. Functions as a means. As an example, the change determination time operation control unit 114 is controlled by operation control of various devices included in the output unit 140 (for example, an image display device, a sound output device, a light emitting device, or a part or all of these). When the transmission frequency is changed from the transmission prohibited section to the transmittable section, the detection of the frequency change operation is notified in a different notification mode from when the transmission frequency is changed from the transmittable section to the transmission prohibited section. That is, the change determination operation control unit 114 determines that the second frequency change operation has been executed when the frequency change determination processing unit 113 determines that the first frequency change operation has been executed. The detection of the frequency changing operation is notified in a different notification mode from that of the operation. As another example, the change determination time operation control unit 114 restricts (stops) transmission of a radio signal by the radio communication unit 120 when the transmission frequency is changed from a transmittable zone to a transmission-prohibited zone. That is, the change determination time operation control unit 114 restricts (stops) the transmission of the radio signal by the radio communication unit 120 when the frequency change determination processing unit 113 determines that the second frequency change operation has been performed. Let As described above, the change determination operation control unit 114 realizes a function as a change determination operation unit in cooperation with the output unit 140, the wireless communication unit 120, and the like.

  Next, the operation (action) of the wireless transmitter 100 in this embodiment will be described focusing on the processing executed by the control unit 110. FIG. 2 is a flowchart illustrating an example of the frequency division setting process executed by the control unit 110 and the like. The frequency partition setting process 111 may be started by the frequency partition setting processing unit 111 when, for example, the user operates the input unit 130 to instruct the start of the frequency partition setting.

  In the frequency division setting process shown in FIG. 2, the frequency division setting processing unit 111 included in the control unit 110 first selects a radio wave format from a plurality of types (step S101). At this time, for example, the frequency division setting processing unit 111 displays a radio wave format selection screen on the image display device included in the output unit 140, and can be selected in advance based on the operation of the input unit 130 by the user according to the display. A desired radio wave format may be selected from a plurality of types of radio wave formats prepared in the above. Moreover, you may make it select the band which sets a frequency division from the operating frequency band in the wireless communication part 120 with a radio wave format. Note that the radio wave format may be selected without displaying the radio wave format selection screen, for example, when the user performs a predetermined key operation on the input unit 130.

  Following the selection of the radio wave format in step S101, an edge frequency that is a boundary frequency is set (step S102). At this time, for example, the frequency section setting processing unit 111 displays an edge frequency setting screen on the image display device included in the output unit 140, and based on the operation of the input unit 130 by the user according to the display, the wireless communication unit Within the operating frequency band at 120, a single or multiple edge frequencies may be set. Note that the upper limit frequency and the lower limit frequency of the operating frequency band in the wireless communication unit 120 may be set in advance as edge frequencies. In this case, the operation frequency band can be divided into a plurality of (two) frequency sections simply by setting a single edge frequency within the operation frequency band in the process of step S102. Further, without displaying the edge frequency setting screen, the edge frequency may be set according to, for example, a user performing a predetermined key operation on the input unit 130.

  After the edge frequency is set in step S102, it is set whether a plurality of frequency partitions divided by the edge frequency are to be transmittable partitions or transmission prohibited partitions (step S103). At this time, for example, the frequency section setting processing unit 111 displays a transmission enable / disable setting screen on the image display device included in the output unit 140, and based on the operation of the input unit 130 by the user according to the display, What is necessary is just to set a frequency division to either a transmission possible division or a transmission prohibition division. It should be noted that, without displaying the transmittable / prohibited setting screen, for example, when the user performs a predetermined key operation on the input unit 130, the transmittable section and the transmit prohibition section are set. It may be.

  Following the setting of the transmittable section and the transmission prohibited section in step S103, it is determined whether or not to further set the frequency section based on, for example, an operation of the input unit 130 by the user (step S104). At this time, if there is no further frequency section setting (step S104; No), the frequency section setting process ends. On the other hand, when there is a further frequency section setting (step S104; Yes), the process returns to step S101 to set a new frequency section. It should be noted that not only the process of step S101 but also the process of step S102 or step S103 can be returned so that the setting of the edge frequency and transmission enable / disable can be performed individually.

  Such a frequency section setting process may be executed by the wireless transmitter 100, but may be executed by a separate information processing apparatus such as an external computer different from the wireless transmitter 100, for example. In this case, data indicating various setting contents by the frequency division setting process may be transmitted from the external information processing apparatus to the wireless transmitter 100 via a connection cable, a telecommunication network, or the like. For example, data received via a cable connector or a network interface included in the input unit 130 may be stored in the storage unit 150 so as to be readable. Alternatively, an information recording medium on which data indicating various setting contents by the frequency section setting process is recorded may be mounted so as to be readable by the storage unit 150.

  Here, the area of the wireless transmitter 100 (for example, the country), the qualifications that the user has (for example, the grade of amateur radio engineer qualification), the radio wave format used by the wireless transmitter 100, and the like. Depending on the radio wave regulations of each country, the specifications of the wireless communication system, etc., the setting contents of the frequency division according to the usage situation may be fixed and unified to a certain extent. In such a case, for example, a manufacturer or a maintenance company of the wireless transmitter 100 can use data indicating various setting contents by the above-described frequency section setting processing to correspond to various usage situations of the wireless transmitter 100. A plurality of types may be created and stored in the storage unit 150 in advance. Then, the frequency division setting processing unit 111 selects the data corresponding to the usage status of the wireless transmitter 100 from a plurality of types of data stored in the storage unit 150 based on information and instructions input from the input unit 130. Then, the setting of the edge frequency indicated by the selected data may be performed. Thereby, the user using the wireless transmitter 100 operates the input unit 130, for example, to determine the area in which the wireless transmitter 100 is used, the qualifications the user has, and the radio wave format to be used. By simply inputting information and instructions for specifying the usage status, it is possible to set the edge frequency suitable for the usage status flexibly and easily.

  Also, for example, data indicating edge frequency settings created by a manufacturer or maintenance company of the wireless transmitter 100 is recorded and distributed on an information recording medium that can be attached to and detached from the storage unit 150, and the user or the like. May be installed in the storage unit 150 so as to be readable. Thereby, setting the edge frequency suitable for various use situations of the wireless transmitter 100 while suppressing an increase in the storage capacity in the fixed (non-detachable) storage unit 150 included in each wireless transmitter 100, It can be done flexibly and easily.

  Further, information indicating the setting contents of the edge frequency created by, for example, a manufacturer or a maintenance company of the wireless transmitter 100 is information installed outside the wireless transmitter 100 via a telecommunication network such as the Internet. Data distributed from a processing device (a computer including a server or the like) and received via a network interface included in the input unit 130 may be stored in a readable manner in the storage unit 150. Thereby, it is possible to flexibly and easily perform setting of an edge frequency suitable for various use situations of the wireless transmitter 100 while suppressing an increase in storage capacity in the storage unit 150 included in each wireless transmitter 100. it can.

  Information and instructions for specifying the usage status of the wireless transmitter 100 are not limited to those input by the user by operating the input unit 130. For example, a region (for example, a country) where the wireless transmitter 100 is used uses a position information acquisition device such as a GPS (Global Positioning System) device or an electronic compass circuit incorporated in or attached to the control unit 110, or The wireless communication unit 120 may be specified by performing wireless communication with a predetermined wireless base station.

  Hereinafter, an example of specific setting contents such as an edge frequency by the above-described frequency division setting process will be described. In this specific example, it is assumed that the wireless transmitter 100 is used as an amateur wireless transmitter. In Japan, for example, a 1.9 MHz band (1,810 kHz to 1,912.5 kHz) and a 3.8 MHz band (3,702 kHz to 3,805) as shown in FIGS. (kHz), 7 MHz band (7,000 kHz to 7,100 kHz), 14 MHz band (14,000 kHz to 14,350 kHz), and the like are usable. In the wireless transmitter 100, these frequency bands should just be preset as an operating frequency band of the wireless communication part 120, for example.

  Here, within each frequency band, the usable band may be limited depending on the type of radio wave format. For example, in the case of the 7 MHz band, transmission in the CW mode (telephone) is permitted at 7,000 kHz to 7,030 kHz, while transmission in the telephone mode is not permitted. In addition, bands where transmission is prohibited may be scattered within a certain frequency band. For example, transmission in the range of 1,825 kHz to 1,907.5 kHz is not permitted in the 1.9 MHz band, and in the range of 3,716 kHz to 3,745 kHz and in the range of 3,770 kHz to 3,791 kHz in the 3.8 MHz band. Transmission is not allowed.

  Corresponding to such restrictions, the frequency partition setting processing unit 111 executes the frequency partition setting process described above, for example, to create table data constituting the frequency partition management table 200 as shown in FIG. What is necessary is just to set a frequency. In the frequency partition management table 200 shown in FIG. 4, the operating frequency band of the wireless communication unit 120 set in advance, the radio wave format that is the signal format of the wireless signal, the transmittable partition that enables transmission of the wireless signal, the boundary The edge frequency that is the frequency is associated. Note that items associated in the frequency partition management table 200 are not limited to those illustrated in FIG. 4, and may be any items that can specify settings such as edge frequencies. For example, instead of setting the transmittable section, a transmission prohibited section may be set. Further, if the upper limit frequency and the lower limit frequency in the setting of the transmittable section and the transmission prohibition section are designated as the edge frequency, there is no need to separately provide an edge frequency item.

  Thereby, it is possible to newly provide a transmittable section and a transmission prohibited section within the preset operating frequency band of the wireless communication unit 120. For example, in the case of the 1.9 MHz band, 1,825 kHz and 1.907.5 kHz are designated as edge frequencies, the range of 1,810 kHz to 1,825 kHz and the range of 1,907.5 kHz to 1,912.5 kHz are set as transmittable sections, and 1,825 kHz to 1,907.5 kHz. May be set as a transmission prohibited section. Here, the number of transmittable sections and transmission-prohibited sections can be set arbitrarily (single or plural). For example, in the case of the 3.8 MHz band, 3,716 kHz, 3,745 kHz, 3,770 kHz, and 3,791 kHz are designated as edge frequencies, the range of 3,702 kHz to 3,716 kHz, the range of 3,745 kHz to 3,770 kHz, and the range of 3,791 kHz to 3,805 kHz. The range may be set as a transmittable section, and the range of 3,716 kHz to 3,745 kHz and the range of 3,770 kHz to 3,791 kHz may be set as a transmission prohibited section. Further, different frequency sections depending on the radio wave format can be set as transmission prohibited sections. For example, in the case of the 7 MHz band, the range from 7,000 kHz to 7,030 kHz is set as a transmittable zone corresponding to only the CW mode, while the phone mode is set as a transmission prohibited zone, and the range from 7,030 kHz to 7,100 kHz is set to the CW mode and the phone mode. It is sufficient to set the transmission possible section corresponding to both.

  As described above, data indicating edge frequency settings such as the frequency partition management table 200 shown in FIG. 4 may be created by an information processing device separate from the wireless transmitter 100. In addition, for the setting of frequency sections that are fixedly and uniformly defined to a certain extent according to radio wave regulations and radio communication system specifications, such as the amateur radio use category shown in FIG. May be generated by a manufacturer or maintenance company of the wireless transmitter 100 and distributed in a state where it is recorded on an information recording medium, or distributed via a telecommunication network. As described above.

  Further, for example, according to the qualifications possessed by the user who uses the wireless transmitter 100, among the operating frequency bands set in advance as usable by the wireless communication unit 120, the entire frequency band in a certain range is set as a transmission prohibited section. It can also be set. For example, when the grade of amateur radio engineer qualification possessed by the user is “class 4”, transmission in the 14 MHz band as shown in FIG. 3D is not permitted. In this case, with respect to the 14 MHz band, 14,100 kHz and 14,350 kHz may be designated as edge frequencies, and the entire 14 MHz band may be set as a transmission prohibited section.

  Furthermore, arbitrary frequency divisions can also be set according to the use situation of the wireless transmitter 100 different from a fixed and uniform rule of a certain degree due to, for example, radio wave regulations or wireless communication system specifications. For example, in a contest that competes for the level of proficiency in amateur radio technology, the transmission frequencies that can be used may be limited. As a specific example, in the 7 MHz band, a usable transmission frequency is limited to a range of 7,040 kHz to 7,080 kHz. In this case, 7,040 kHz and 7,080 kHz are designated as edge frequencies, the range from 7,040 kHz to 7,080 kHz is set as a transmittable zone, and the range from 7,000 kHz to 7,040 kHz and the range from 7,080 kHz to 7,100 kHz are set as transmission prohibited zones. And it is sufficient.

  Based on the frequency section set in this way, the wireless transmitter 100 can perform various operations that are predetermined operations when the transmission frequency is changed. FIG. 5 is a flowchart illustrating an example of a transmission operation control process executed by the control unit 110 and the like. The transmission operation control process may be started by the transmission operation control unit 112 or the like when, for example, the user operates the input unit 130 to instruct the start of radio signal transmission.

  In the transmission operation control process shown in FIG. 5, the transmission operation control unit 112 included in the control unit 110 first selects a radio wave format to be used for transmitting a radio signal (step S121). At this time, the transmission operation control unit 112 displays, for example, a radio wave format selection screen on the image display device included in the output unit 140, and can be selected in advance based on the operation of the input unit 130 by the user according to the display. A desired radio wave format may be selected from a plurality of types of radio wave formats prepared. The radio wave format is not limited to selecting the radio wave format based on the operation of the input unit 130 by the user. For example, the radio wave format designated as the initial setting may be selected by reading the stored data in the storage unit 150. The radio wave format specified at the end of the previous use may be selected.

  Following the selection of the radio wave format in step S121, initial setting of the transmission frequency is performed (step S122). At this time, the transmission operation control unit 112 displays a transmission frequency setting screen on the image display device included in the output unit 140, for example, and based on the operation of the input unit 130 by the user according to the display, the wireless communication unit 120 The transmission frequency (operation frequency) at the time of transmitting the radio signal may be set by the above. At this time, the frequency band in which the transmission frequency is set may be selected from the operating frequency band in the wireless communication unit 120. The transmission frequency is not limited to setting the transmission frequency based on the operation of the input unit 130 by the user. For example, the transmission frequency specified as the initial setting may be set by reading the stored data in the storage unit 150, or the previous time. The transmission frequency specified at the end of use may be used. Alternatively, the radio frequency format may be selected in step S121 after initial setting of the transmission frequency in step S122.

  Based on the radio wave format selection result in step S121 and the transmission frequency setting result in step S122, settings for starting the transmission of the radio signal are performed (step S123). At this time, the transmission operation control unit 112 may perform setting so as to start transmission of the radio signal by the radio communication unit 120 by outputting various control signals to the radio communication unit 120. Also, the transmission operation control unit 112 refers to the frequency division management table 200 or the like based on, for example, the radio wave format selection result or the transmission frequency setting result to determine whether or not the transmission frequency is within the range of the transmittable section. You may judge. At this time, the transmission operation by the wireless communication unit 120 is started within the range of the transmittable section, while the start of the transmission operation may be restricted within the range of the transmission prohibited section. Then, when the start of the transmission operation is restricted, the fact may be notified by the output unit 150 or the like.

  Thereafter, in the control unit 110, for example, the frequency change determination processing unit 113 determines whether or not the frequency of the radio signal has been changed (step S124). As an example, the frequency change determination processing unit 113 determines whether or not the user has operated a frequency setting dial or the like included in the input unit 130, and specifies whether or not there has been an instruction to change the frequency according to the determination result. do it.

  When it is determined in step S124 that there is a frequency change (step S124; Yes), it is determined whether the frequency change exceeds the edge frequency (step S125). At this time, for example, the frequency change determination processing unit 113 identifies the transmission frequency before and after the change. Then, for example, by referring to the frequency division management table 200 as shown in FIG. 4, among the edge frequencies set according to the operating frequency band and the radio wave format, there are those in which the transmission frequency is changed across the transmission frequency. Or not. In other words, the transmission frequency before the change is higher than the specific edge frequency while the transmission frequency after the change is lower than the edge frequency, or the transmission frequency before the change is lower than the specific edge frequency. On the other hand, if the transmission frequency after the change is higher than the edge frequency, the transmission frequency is changed across the edge frequency, so it is determined that the frequency change exceeds the edge frequency. To do.

  When it is determined in step S125 that the frequency change exceeds the edge frequency (step S125; Yes), it is determined whether the frequency change is a change to a transmittable section (step S126). At this time, for example, the frequency change determination processing unit 113 refers to the frequency partition management table 200 as shown in FIG. 4, for example, and the transmission frequency after change is set according to the operating frequency band and radio wave format. What is necessary is just to determine whether it is in the range of a possible division.

  When it is determined in step S126 that it is a change to a transmittable section (step S126; Yes), for example, the change determination time operation control unit 114 performs a notification operation in a predetermined first notification mode. (Step S127). Here, as the notification operation control pattern for controlling the notification operation in the first notification mode, the first notification operation control pattern corresponding to the case where the frequency change from the transmission prohibited section to the transmittable section is performed is performed. The data to be configured may be stored in advance in the storage unit 150 or the like. In this case, the change determination time operation control unit 114 outputs a control signal according to the first notification operation control pattern read from the storage unit 150 to the output unit 140, thereby performing the notification operation in the first notification mode. Let it run.

  Following the setting in step S127, a setting for permitting the transmission of the radio signal is performed in response to the frequency change from the transmission prohibited section to the transmittable section being performed (step S128). For example, in the process of step S128, the change determination time operation control unit 114 outputs a control signal indicating transmission permission to the wireless communication unit 120, thereby starting (or resuming) transmission of the wireless signal by the wireless communication unit 120. Control may be performed. The change determination time operation control unit 114 sends a notification to the transmission operation control unit 112 that it has become a transmittable section, and the transmission operation control unit 112 sends a control signal indicating permission to transmit to the wireless communication unit 120. May be transmitted.

  When it is determined in step S126 that the change is to the transmission prohibited section and not to the transmittable section (step S126; No), for example, the change determination time operation control unit 114 sets the first notification mode. Is set to perform a notification operation in a second notification mode that is predetermined as a different notification mode (step S129). Here, as a notification operation control pattern for controlling the notification operation in the second notification mode, a second notification operation control pattern corresponding to a case where a frequency change is made to shift from the transmittable section to the transmission prohibited section is performed. The data to be configured may be stored in advance in the storage unit 150 or the like. In this case, the change determination time operation control unit 114 outputs a control signal according to the second notification operation control pattern read from the storage unit 150 to the output unit 140, thereby performing the notification operation in the second notification mode. Let it run.

  Following the setting in step S129, a setting for prohibiting transmission of a radio signal is performed in response to the frequency change from the transmittable section to the transmission prohibited section being performed (step S130). For example, in the process of step S130, the change determination operation control unit 114 outputs a control signal indicating prohibition of transmission to the wireless communication unit 120, thereby prohibiting (stopping) transmission of the wireless signal by the wireless communication unit 120. Control may be performed as follows. The change determination time operation control unit 114 sends a notification to the transmission operation control unit 112 that the transmission is prohibited, and a control signal indicating transmission prohibition from the transmission operation control unit 112 to the wireless communication unit 120. May be transmitted.

  When it is determined in step S124 that there is no frequency change (step S124; No), when it is determined in step S125 that the frequency change does not exceed the edge frequency (step S125; No), or After the process of step S128 or step S130 is executed, it is determined based on, for example, the operation of the input unit 130 by the user, whether or not to end the wireless signal transmission operation (step S131). At this time, if it is determined that the transmission operation is to be ended (step S131; Yes), for example, the transmission operation control unit 112 outputs a control signal indicating the transmission end to the wireless communication unit 120. After setting for terminating the signal transmission operation (step S132), the transmission operation control process is terminated. On the other hand, when it is determined that the transmission operation is not terminated (step S131; No), the process returns to the process of step S124 to determine whether or not there has been a frequency change. In addition, when an operation frequency band or radio wave format change is instructed, the transmission operation control unit 112 outputs various control signals to the wireless communication unit 120 in response to the instruction. And control for changing the radio wave format may be executed.

  FIG. 6 shows a specific operation example of the notification operation in the first notification mode and the second notification mode. As the notification operation in the first notification mode corresponding to the frequency change from the transmission prohibited section to the transmittable section, some or all of various notification operations as shown in FIGS. 6A1 to 6A3 are included. It only has to be executed. On the other hand, as the notification operation in the second notification mode corresponding to the frequency change that shifts from the transmittable section to the transmission-prohibited section, one of various notification operations as shown in FIGS. 6 (B1) to (B3). It is sufficient that part or all is executed.

  Here, FIGS. 6A1 and 6B1 show specific examples in the case where the sound output operation by the speaker 141 included in the output unit 140 is executed as the notification operation. In the first notification mode, for example, a sound “ping pong” as shown in FIG. On the other hand, in the second notification mode, for example, a sound “Bubble” as shown in FIG. In the first notification mode and the second notification mode, for example, a user can determine whether a transmission enabled zone or a transmission prohibited zone is set by changing the pitch (audio frequency), audio content, melody, and the like output from the speaker 141. Can be identified.

  FIGS. 6A2 and 6B2 show a specific example in the case where the operation of turning on (or turning off) the LED 142 included in the output unit 140 is executed as a notification operation. In the first notification mode, for example, the LED 142 is lit in green as shown in FIG. 6 (A2). In contrast, in the second notification mode, for example, the LED 142 is lit in red as shown in FIG. 6 (B2). Alternatively, in the second notification mode, the LED 142 may be turned off. In the first notification mode and the second notification mode, for example, by switching on / off the LED 142, or by changing the emission color when the LED 142 is turned on, the transmission is possible or the transmission is prohibited. The user can be identified.

  6A3 and 6B3 show specific examples in the case where the screen display by the image display device 143 included in the output unit 140 is executed as a notification operation. And in a 1st alerting | reporting aspect, the character of "being able to transmit" as shown, for example in FIG. 6 (A3) is displayed. On the other hand, in the second notification mode, for example, the characters “transmission prohibited” as shown in FIG. 6 (B3) are displayed. The character to be displayed may be any character as long as it is different between the first notification mode and the second notification mode. Also, it is not limited to the operation of displaying characters, for example, an arbitrary display operation such as an operation of displaying a predetermined character image, background image, or moving image, an operation of changing a display color, or an operation of switching between blinking display and fixed display. As long as the notification operation is performed in the first notification mode or the second notification mode. In the first notification mode and the second notification mode, the display operation content in the image display device 143 may be made different so that the user can identify whether it has become a transmittable zone or a transmission prohibited zone.

  As described above, according to the present invention, an edge frequency is set as a boundary frequency for dividing an operating frequency band set in advance corresponding to the wireless communication unit 120 into a plurality of frequency sections, and each frequency is set. The section is set as either a transmittable section or a transmission prohibited section. At this time, different edge frequencies can be set according to the type of radio wave format that is the signal format of the radio signal. Then, it is determined whether or not there has been a frequency change across the edge frequency, and when such a frequency change has occurred, for example, a notification operation or transmission in the first notification mode corresponding to the change to the transmittable section A predetermined operation such as a notification operation in the second notification mode corresponding to the change to the prohibited section or a wireless signal transmission restriction (stop) corresponding to the change to the transmission prohibited section is executed. Thereby, an edge frequency (boundary frequency) can be set flexibly within the operating frequency band, and an appropriate operation can be realized with respect to a change in transmission frequency across the edge frequency.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible without departing from the spirit of the invention.

  The wireless transmitter 100 in the above embodiment may be integrated with a wireless receiver that receives a wireless signal, and may be included in a wireless communication device that can transmit and receive the wireless signal. In this case, it is sufficient that the operating frequency is used not only as the transmission frequency but also as the reception frequency, and the radio signal can be transmitted or received at the operation frequency. Then, the frequency change determination processing unit 113 determines, for example, whether or not the operating frequency has been changed, or determines whether or not the operating frequency has been changed across the edge frequency that is the boundary frequency when the operating frequency has been changed. It is only necessary to function as a process for performing various determinations relating to changes in the operating frequency. Further, the change determination time operation control unit 114 only needs to be able to notify the detection of the frequency change operation in the same manner as in the above embodiment when the operating frequency is changed across the edge frequency. However, when receiving a radio signal, it was transmitted in the transmission prohibited section without restricting (stopping) the reception of the radio signal even when the operating frequency was changed from the transmittable section to the transmission prohibited section. You may enable it to receive a radio signal. Thus, for example, in an amateur radio technology contest, a radio signal transmitted in the transmission prohibited section while notifying that the operating frequency has been changed from the transmittable section to the transmission prohibited section can be easily recognized. Can be used for wireless skill proficiency assessment. The configuration for performing such a receiving operation can be applied to, for example, a wireless receiver that can only receive a wireless signal.

  That is, the present invention relates to a wireless communication apparatus capable of executing at least one of transmitting and receiving a radio signal by changing an operating frequency within a preset operating frequency band. An edge frequency that is a boundary frequency for dividing into multiple frequency sections is set, it is determined whether the operating frequency has been changed across the edge frequency, and a determination is made that the operating frequency has been changed across the edge frequency Sometimes, it may be anything that can execute a predetermined operation.

  In the above embodiment, the control unit 110, the input unit 130, the output unit 140, and the storage unit 150 have been described as constituting a single wireless transmitter 100 together with the wireless communication unit 120 and the antenna 121. In contrast, an information processing apparatus such as a computer including the control unit 110, the input unit 130, the output unit 140, the storage unit 150, and the like may be configured separately from the wireless communication unit 120 and the antenna 121. . In this case, for example, by installing an operation program for realizing each functional configuration by the control unit 110 or the like in the above-described embodiment in a computer as an information processing apparatus, each process in the above-described embodiment is executed in a general-purpose computer. Can be made. That is, the function as the wireless transmitter 100 in the present invention may be realized by causing an existing computer to execute an operation program similar to the operation program executed by the control unit 110 in the above embodiment.
