Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying a transmission / reception signal strength of a display unit in a wireless communication device.

[0002]

2. Description of the Related Art In a conventional radio communication device of this kind,
For example, as shown in FIG. 6, there is a display which is displayed by an icon (icon) or the like, and the display content is simply displayed in accordance with a level change relating to transmission or reception.

[0003] In addition, there is a digital display, but an analog display (so-called S meter display) is performed, and in any case, the display content is uniformly displayed.

[0004]

However, in the prior art as described above, when the level related to transmission or reception is viewed from the viewpoint of actual operation, the display content is immediately specified. Determining the level of has a drawback that it is extremely difficult to read the actual level (numerical value) if there is a level change that tends to occur at the time of reception even if it can be intuitively known.

[0005] In addition, since icons and the like are used for display, only one type of display can be performed, and it is impossible for an operator of the wireless communication device to express an arbitrary character.

The present invention has been made for the purpose of improving such disadvantages of a conventionally known character display method.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and uses a display member such as an LCD in a wireless communication device for displaying an output signal level of a transmission / reception section on a display section. The displayed characters on the display unit are displayed in multi-stage or one-stage, and can be changed to any character.

A display content setting section for inputting setting conditions for performing these displays, character reference data previously stored in a memory of a microcomputer, reference data of the memory and display content setting The display of the display unit is controlled by the memory and the CPU via an interface based on input data of the unit and output data related to a transmission / reception signal.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a method for displaying the strength of transmission / reception signals according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows a transmission unit 1, a reception unit 2, a display content setting unit 3, and a display unit 5. And a software part of the microcomputer 4 for controlling the hardware part.

FIG. 2 shows an embodiment of the display unit 5, and FIGS. 3 to 5 are flowcharts of a control program executed by the microcomputer 4.

It should be noted that P1 to P shown in FIGS.
Reference numeral 27 denotes each step of the above-mentioned flowchart, and in the following text, the corresponding part is shown in parentheses.

Next, the operation of FIG. 1 will be described functionally.
The transmitting unit 1 or the receiving unit 2 has a function of detecting the respective signal output data, and the display content setting unit 3 selects various characters and sets a display position thereof for data input. The display unit 5 is constituted by a dot matrix LCD or the like.

On the other hand, the microcomputer 4 uses the signal output data of the transmitting and receiving units 1 and 2 and the input data of the display content setting unit 3 to control the interface 41 based on the control program information stored in the memory 42 in advance. After adjusting the input / output signals, the CPU 43 performs arithmetic processing.

Hereinafter, the operation of the present invention will be described in detail. First, a wireless communication device is activated in advance from the flowchart for performing "transmission output level display" in FIG.
1) After that, the transmission mode to be actually operated is set (P2).

Next, the transmission output level is detected from the transmission section 1 (P3), and a specified output level is set (P4).

Then, when the transmission output is M (for example, 5 W), the display unit 5 displays from the left end to M (P5).

When the transmission output is changed (P6)
Returns to the step (P3) for detecting the transmission output level again, and if not changed, shifts to another mode in the next step (P7).

Next, from the flowchart for "reception signal level display" shown in FIG. 4, a reception mode to be actually operated is set (P8), and a reception signal from the reception section 2 is detected (P9). Later, the strength (level) of this received signal
Is determined (P10).

The strength of the received signal is N (for example, 9)
In this case, the display unit 5 displays the area from the left end to the N (P11).

Further, a judgment to shift to another mode (P12)
Is performed, the process proceeds to the next step (P13). If not, the received signal is detected again (P9).
Return to (P12).

Next, from the flowchart for "display method setting" of FIG. 5, the type of character to be displayed on the display unit 5 and the display content change mode for changing its position are set (P14). , Of these changes,
It is determined whether the position of the display character is to be displayed in multiple digits (in the embodiment, a maximum of eight digits) or one digit (P1).
Five).

If a multi-digit display is to be performed, the display contents are set by the display contents setting unit 3 to the microcomputer 4.
To be processed by the CPU 43 via the interface 41 (P16, P17).

Next, the result obtained by the above-described arithmetic processing is written into a RAM (not shown) of the memory 42, and the Sn-th display from the left is set as a display on the display unit 5 (P18).

Further, an arbitrary character is set at the display position of the display unit 5 based on the character reference data (ROM (not shown)) in the memory 42 and the setting data (P19). -For example (a) to (d), (f) and (g) in FIG.

Next, among the characters of up to eight digits as the display contents of the display unit 5, the above step (P1
It is determined whether or not the setting value or character in 8) is changed (P20).

If the display content of the display unit 5 is to be changed, the process returns to the step (P17 to P19) for performing the arithmetic processing based on the input data of the display content setting unit 3, and if not, the display content change mode Is completed (P27).

On the other hand, when the position of the display character is displayed by one digit, the display position is determined arbitrarily (P21), and the content is input to the microcomputer 4 to be processed by the CPU 43 through the interface 41. (P22, P23).

Next, the result obtained by the above arithmetic processing is written into a RAM (not shown) of the memory 42, and the display level position of the display unit 5 is set to the T-th position (P24).

Further, an arbitrary character is set at the display position of the display unit 5 based on the character reference data (ROM (not shown)) in the memory 42 and the setting data (P25). -E.g. FIG.

Next, among the display positions of up to eight digits as display contents of the display unit 5, the above-mentioned step (P24)
It is determined whether or not the set value or character is changed (P26).

If the display content of the display unit 5 is to be changed, the process returns to the steps (P23 to P25) for performing arithmetic processing based on the input data of the display content setting unit 3, and if not, the display content change mode. Is completed (P27).

In the case where the reception display mode is displayed by one digit, an average value detection means or a delay holding means of several seconds (about 1 to 2 seconds) is taken into consideration in advance that the intensity of the reception signal may fluctuate rapidly. By adding (not shown) or the like, it is possible to make the numerical value of the received signal strength easy to see.

Although the display contents of the present invention are configured to have a maximum of eight digits, the present invention is not limited to this, together with the type of character.

[0034]

Since the present invention is constructed as described above, it has the following excellent effects.

Since the transmission output level of the transmission unit or the reception signal level of the reception unit is directly indicated by numerical values, the level value can be immediately read, which is convenient.

Further, when one-digit display is performed, it is particularly effective for a display portion having a small display area such as a portable radio communication device.

Also, since various characters can be expressed, the personality of the operator (user) is displayed by displaying the name, call sign, etc. of the operator (user), and the password of the prior art is encrypted. If used together with the lock function, the name of the owner can be displayed,
It helps prevent theft.
