Description

  The present invention relates to a wireless communication device in which an operation unit is configured by a liquid crystal display with a touch panel. More specifically, the operation input specific to the wireless communication device is based on a touch operation that is intuitively easy to understand, thereby improving operability. It is intended.

  Conventionally, in a wireless communication device, as shown in FIG. 17, various operation keys and dials are arranged around a liquid crystal display unit provided almost at the center of an operation panel surface, and the operation conditions of the wireless communication device are determined by these operations. The operation is set and the status is displayed on the liquid crystal display. Characters indicating the respective functions are printed or stamped on the surface of each operation key.

As shown in FIG. 18, status display is performed on the liquid crystal display unit in the same manner as described above, but icons and characters (FIG. In some cases, the black and white characters are displayed and the contents of the icons and characters are sequentially changed by the operation of a specific key so that each operation key can be assigned to a plurality of functions in software.
According to this method, the number of mechanical operation keys arranged can be reduced.

  By the way, in the method using the fixed operation keys in FIG. 17, when the wireless communication device is downsized, the size of the liquid crystal display unit must be reduced in order to secure an operation key arrangement area. Furthermore, since it is necessary to print or engrave a functional character on the surface of each operation key, the man-hour is increased and the manufacturing cost is increased.

  Further, according to the software function assignment method for each operation key shown in FIG. 18, although the number of operation keys can be reduced as described above, icons and characters are displayed in the peripheral area of the liquid crystal display unit. The display area such as the operation state becomes so small, and it is not so advantageous from the viewpoint of the display area.

  On the other hand, in the case of a radio communication device used in amateur radio, it is obliged that the operating frequency can be confirmed. Therefore, as shown in FIGS. 17 and 18, it is common to display the frequency on the liquid crystal display unit. In addition, more recently, the signal strength of the operating frequency is also displayed.

  Therefore, it is necessary to display information related to other functions while constantly displaying the operating frequency. However, as shown in Patent Document 1, when a liquid crystal display with a touch panel is used, most of the operation keys are touched. Therefore, a larger-sized liquid crystal display can be used, and clearer function information can be displayed.

However, in the case of a wireless communication device, compared to other electronic devices, there are a wide variety of operations, and they are often technical and complicated. It takes considerable experience and skill to do.
In Patent Document 1, a predetermined function is executed by a touch operation on an arbitrary area of the touch panel, or at most a touch operation divided into a right area and a left area. It is not related to the display content of the liquid crystal display unit, but it is necessary to store the association between the touch operation and the touch area and the effect in advance according to the instruction manual etc., so this method is not familiar to wireless communication devices It is.
Note that the operation guidance will be enhanced if the contents of the selection menu are displayed with characters and icons in the area to be touched as conventionally used in ATM (automated teller machine), etc. The area narrows the display area of the operating frequency.

  Therefore, the present invention uses a liquid crystal display with a touch panel on the operation panel of the wireless communication device, and has a configuration in which various related function setting operations can be intuitively performed from the display screen of the set frequency and received signal strength. The purpose is to provide.

The first invention is operable in a plurality of frequency bands, and has a liquid crystal display with a transparent touch panel on an operation panel, and sets a frequency display area for each frequency band in the liquid crystal display. A wireless communication device for displaying a frequency, the static pressure detecting means for detecting a static pressure on the surface area of the transparent touch panel corresponding to each frequency display area in the liquid crystal display, and the static pressure detecting means Comprises a frequency setting means for setting the frequency displayed in the frequency display area of the liquid crystal display corresponding to the static pressure detection area in the transparent touch panel as an operating frequency when the static pressure is detected. The present invention relates to a wireless communication device.
In the present invention, when the frequency display area in the liquid crystal display is statically pressed with a finger, a stylus pen or the like (hereinafter referred to as “finger or the like”), the area information related to the static press is obtained from the transparent touch panel, and the liquid crystal display Based on the correspondence between the frequency of the display and the frequency display area, the selection and setting of the operating frequency is performed by a static pressing operation.
According to the present invention, the operation frequency setting, which is an operation related to the frequency in the wireless communication device, is performed by a touch operation (static pressing operation) with a finger or the like on the frequency display region provided for each operable frequency band. As a matter of course, a mechanical operation key for setting the operation frequency is not necessary, and direct and intuitive operability can be realized as compared with the conventional key operation.

In the first aspect of the present invention, if icon display means for displaying an icon in the vicinity of the frequency display area related to the operating frequency set by the frequency setting means in the liquid crystal display is provided, any frequency among a plurality of frequencies is provided. You can easily know if it is operated by
Further, a determination unit is provided for determining whether or not a static pressure detection time by the static pressure detection unit is a predetermined time or more, and the determination unit determines that the static pressure detection time is a predetermined time or more. If the display control means for the liquid crystal display displays only the operating frequency set by the frequency setting means, the operator can display the frequency display area to be set for a predetermined time. By simply pressing the above, the frequency can be set as the operating frequency, and the display of other frequencies can be eliminated, making it easy to see only the operating frequency.
From the viewpoint of the operator, it is possible to select whether to display a plurality of frequencies including the operating frequency or to enlarge only the operating frequency by adjusting the static pressing time.

A second invention is a wireless communication device having a liquid crystal display with a transparent touch panel on an operation panel, and displaying a frequency by setting a frequency display area on the liquid crystal display, the frequency in the liquid crystal display A sliding pressure detecting means for detecting the sliding pressure in the left-right direction and the direction information on the surface area of the transparent touch panel corresponding to the display area, and the sliding pressure detecting means detected a sliding pressure in the right direction. In the case, the sliding press detection is performed for the frequency scanning for a predetermined band equal to or higher than the frequency displayed in the frequency display area of the liquid crystal display corresponding to the surface area of the transparent touch panel on which the sliding press is performed. When the means detects a sliding pressure in the left direction, the frequency display of the liquid crystal display corresponding to the surface area of the transparent touch panel where the sliding pressure is made The frequency scanning of the following predetermined band frequency displayed on the frequency, according to the radio communication apparatus, characterized by comprising a scanning means to execute respectively.
This invention uses the fact that the sliding pressing operation for the frequency display area in the liquid crystal display is an instruction operation for the frequency scanning operation, and the sliding pressing includes the direction information unlike the static pressing, and the sliding to the left is performed. The dynamic pressing is frequency scanning to the low frequency band side, and the sliding pressing to the right is frequency scanning to the high frequency band side.
According to this invention, as in the case of the first invention, an operation closely related to frequency is performed by a direct contact operation (sliding pressing operation) on the frequency display area in the wireless communication device, and In graphs with frequency on the horizontal axis, such as frequency spectrum, the left side is generally the low frequency band and the right side is the high frequency band. Whether or not to perform scanning can be selected by sliding pressing in a direction in which it is easy to get accustomed sensuously, the relationship between the operation and the effect is easy to understand, and the storage is easy.

In this case, a so-called band scope function is executed.
According to the present invention, an operation of performing a bandscope function (spectrum analysis and display of a result thereof) that is closely related to received signal strength information in a wireless communication device is directly contacted with a display area of the received signal strength information. (Static pressing or sliding pressing operation).
Then, when there is a static pressure, when there is a sliding pressure in the right direction, and when there is a sliding pressure in the left direction, the band is based on the frequency related to the received signal strength information. The scope for executing the scope function is different, but the method of setting each range is easy to get familiar with like the case of the second invention, and the correspondence between the operation and the effect is easy to understand intuitively, Its memory is easy.

Hereinafter, embodiments of a wireless communication device of the present invention will be described in detail with reference to the drawings.
First, FIG. 1 is a block circuit diagram of a 144/430 MHz band FM dual-band mobile transceiver, where 1 is an antenna, 2 is a mylophone, 3 is a microphone input signal amplifier circuit, 4 is a transmitter, 5 is a receiver, 6 Is a speaker output signal amplification circuit, 7 is a speaker, 8 is a microcomputer circuit (hereinafter referred to as “microcomputer circuit”), 9 is an operation unit, 10 is an operation signal input interface, 11 is a liquid crystal display with a transparent touch panel (11a Is a liquid crystal display, 11b is a transparent touch panel), 12 is a driver for the liquid crystal display 11a, 13 is an input interface for an output signal of the transparent touch panel 11b, and they are connected as shown by a signal line and a data bus. .
The entire system is controlled by the microcomputer circuit 8 based on a control program stored in its built-in ROM, and the microcomputer circuit 8 displays various screens on the liquid crystal display 11a based on signals obtained from the transparent touch panel 11b. Execute control.

Here, the operation performed by the transceiver based on the touch operation on the liquid crystal display 11 with the transparent touch panel in relation to the present invention will be described based on the flowcharts of FIGS. 2 to 4, and the liquid crystal on the operation panel surface at each operation stage will be described. Refer to FIGS. 5 to 16 for the display contents on the display 11.
In the transceiver of this embodiment, as shown in FIG. 5, the operation panel surface includes a liquid crystal display 11 with a transparent touch panel and an operation unit 9. The operation unit 9 includes a power switch 21 and a screen switching FWD / BCK. Only key 22 and two dial knobs 23 and 24 and two volume knobs 25 and 26 are arranged, and all other function keys found in conventional wireless communication devices are omitted, and FWD / BCK An equivalent operation can be performed by touching the liquid crystal display 11 with a touch panel while switching the screen with the key 22.
The function of the FWD / BCK key 22 can also be replaced by a touch operation on the liquid crystal display 11 with a touch panel. In this case, the key 22 can be omitted.

The display screen shown in FIG. 5 corresponds to the basic screen in this transceiver, and for each of the two bands (144 MHz band and 430 MHz band), the frequencies adjusted and set as reception frequencies at that time and the received signal strengths at those frequencies are shown. A bar graph (a block increase / decrease formula in the horizontal direction) is displayed (S1).
In the liquid crystal display 11a, each reception frequency and each bar graph are displayed in a predetermined display area. In FIG. 5, 31 and 32 correspond to the frequency display areas in the 430 MHz band and the 144 MHz band, respectively. Reference numerals 33 and 34 correspond to the received signal strength display areas related to the frequencies indicated in the frequency display areas of the respective bands.

Now, when the operator presses the frequency display area of any band with a finger, the microcomputer circuit 8 confirms from the output signal of the transparent touch panel 11b which static pressing is associated with which frequency display area of the band, The frequency information of the band on the pressing side is transferred to the transmission unit 4 and the reception unit 5 and set as the operating frequency (S2, S3).
For example, as shown in FIG. 6, if there is a static pressing with the finger 40 against the frequency display area 31 on the 430 MHz band side, 439.700 MHz is immediately set as the operating frequency, and transmission / reception at the same frequency becomes possible. Become.
In this embodiment, when the operating frequency is set, the microcomputer circuit 8 causes the LCD driver 12 to display a triangular icon 41 in the vicinity of the frequency display area on the band side of the operating frequency (S3 and FIG. 6). , To clearly indicate which band side the current operating frequency is.

Further, when the static pressing time with respect to the frequency display area by the finger 40 exceeds a certain time Tsec (for example, 3 sec), the frequency and the bar graph display in the non-operation side band are deleted, and the frequency of the operation side band and its frequency Only the received signal strength is enlarged and displayed (S4, S5).
Specifically, if the static pressing state in FIG. 6 continues for Tsec or longer, the screen of the liquid crystal display 11a changes as shown in FIG. 7, and the operator displays the operating frequency (31) and the received signal strength which are greatly displayed. You can communicate while checking the information (33).

  Next, unlike the static pressing operation described above, when the operator performs sliding pressing with a finger on the frequency display area 31, 32 of any band, the microcomputer circuit 8 Is detected and confirmed from the output signal of the transparent touch panel 11b, and if it is a sliding press to the right (S6), it is displayed in the frequency display area 31 or 32 that is the target of the sliding press A frequency scanning operation is performed for a band above the frequency (S7). Conversely, if the sliding pressing is to the left (S8), the frequency display area 31 that is the target of the sliding pressing is 31. Alternatively, a frequency scanning operation is performed for a band equal to or lower than the frequency displayed in 32 (S9).

For example, as shown in FIG. 8, when there is a sliding pressing operation in the right direction with the finger 40 on the frequency display region 32 on the 144 MHz band side, the frequency displayed at that time is 144. For the band of 640 MHz or higher, as shown in FIG. 9, the numerical value of the reception frequency range that is sequentially switched is displayed in different colors, and the received signal strength at each frequency that is changed is displayed in the bar graph display area while performing frequency scanning. Ning.
The frequency scanning method includes a method in which a predetermined frequency range is scanned at a predetermined speed, or scanning is stopped at a target frequency, stays at that frequency for a predetermined time, and starts after a predetermined time has elapsed. Although there is a method of restarting scanning, any method may be used.
Further, this frequency scanning operation may be performed on the enlarged display screen of the frequency and the received signal strength of the operating side band shown in FIG. 7, and in that case, only the operating side band as shown in FIG. Is executed while displaying an enlarged screen during frequency scanning.

Furthermore, in the transceiver of this embodiment, not only the contact operation for the frequency display areas 31 and 32 of each band as described above, but also the static pressing or the sliding pressing in the left-right direction on the reception signal intensity display areas 33 and 34. The band scope function can be executed.
First, when the operator makes a static press on the received signal strength display area 33 or 34 of each band with a finger, the microcomputer circuit 8 detects and confirms the static press from the output signal of the transparent touch panel 11b. (FIG. 3: S10), spectrum analysis is performed on the upper and lower predetermined bands centered on the reception frequency set on the band side of the reception signal strength display area 33 or 34 where the pressure is applied, and based on the result. Band scope display is performed with the horizontal axis representing frequency and the vertical axis representing power (FIG. 3: S11).

For example, as shown in FIG. 11, if there is a static pressure by the finger 40 on the received signal strength display area 33 on the 430 MHz band side, as shown in FIG. The band scope display 51 centering on the set frequency of 439.700 MHz is made.
This is the same even when a static pressure is applied by a finger to the reception signal intensity display area 34 on the 144 MHz band side, and band scope displays 51 and 52 are performed for both bands as shown in FIG. It can also be made.
Further, the operation for displaying the band scope may be performed on the operation side band frequency and received signal strength enlarged display screen shown in FIG. 7, and in this case, as shown in FIG. Only the side band is enlarged, and the band scope display (51) is enlarged and detailed for easy viewing.

  Next, when the operator performs a sliding press on the reception signal intensity display area 33 or 34 of each band, the microcomputer circuit 8 determines the sliding press and the left or right direction from the output signal of the transparent touch panel 11b. (Fig. 3: S12, S14), and if it is a sliding press to the right, the band of the received signal strength display area 33 or 34 where the press has occurred Band scope display based on spectrum analysis for a predetermined band above the reception frequency set on the side (Fig. 3: S13), conversely, if it is a sliding press to the left, the press Band scope display is performed based on spectrum analysis for a predetermined band equal to or lower than the reception frequency set on the band side of the received signal strength display area 33 or 34 (FIG. 3: S15).

  For example, FIG. 15 shows a state where the received signal intensity display area 33 on the 430 MHz band side is slid and pressed with the finger 40 in the right direction and the received signal intensity display area 34 on the 144 MHz band side is moved in the left direction. As a result, as shown in FIG. 16, a spectrum analysis of a predetermined band of 431.650 MHz or more is performed on the 430 MHz band side, and the band having 431.650 MHz as the leftmost band is displayed instead of the received signal intensity display on the same band side. A scope display 53 is displayed, and a spectrum analysis of a predetermined band of 144.640 MHz or less is performed on the 144 MHz band side, and a band scope display 54 with 144.640 MHz as the rightmost edge is substituted for the received signal intensity display on the same band side. Is made.

As described above, in the transceiver of this embodiment, the operation frequency can be set, the scan operation start instruction, and the band scope display operation start instruction can be performed by operating the liquid crystal display unit 11 with the transparent touch panel. The predetermined bandwidth that is the target range of the operation and band scope display can be set by displaying another screen with the FWD / BCK key 22.
Further, as shown in steps S21 and S22 of FIG. 4, the display screens obtained by the operations shown in FIGS. 2 and 3 [that is, step S3 (FIG. 6), step S5 (FIG. 7), step S7, In S9 (FIGS. 9 and 10), step 11 (FIGS. 12, 13, and 14), and steps S13 and S14 (FIG. 16)], when a portion other than the number, bar graph, or bandscope display area is pressed The microcomputer circuit 8 that has detected it from the output signal of the transparent touch panel 11b immediately returns to the original basic screen (step S1; FIG. 5) (FIG. 4: S21, S22).
