Description

  The present invention relates to an improvement of an indoor wireless quality measuring device.

  In recent years, an in-vehicle radio wave quality measuring device using a mobile phone that controls a call using a car navigation system and a general-purpose personal computer has been developed and is widely used for outdoor measurement.

  Similarly, for indoor measurements, radio wave quality was measured using a mobile phone controlled by a general-purpose computer.

  A conventional indoor wireless quality measuring apparatus using a map service or GPS information will be briefly described with reference to FIG.

  In FIG. 12, the control unit 105 of the indoor wireless quality measurement device 100 performs the position information and field strength information measured by the GPS module unit 102 and the field strength measurement unit 103 when the position measurement is instructed by operating the button unit 101. Are stored in the memory unit 104. Then, the position information and the electric field strength information accumulated in the memory unit 104 are transmitted to the center via the antenna unit 106 and the base station at a predetermined timing. The center creates a field strength distribution on the map from the position information and field strength information received from the base station.

  As an indoor wireless quality measuring device using GPS information, for example, a mobile communication electric field strength positioning system as disclosed in Patent Document 1 is known.

  However, the conventional indoor wireless quality measuring device has the following problems.

  The first problem is that when measuring indoor electric field strength, there is no public indoor map service, so it is impossible to create an electric field strength distribution on a map.

  The second problem is that the GPS position information cannot be used for indoor floor measurement, and therefore the measurement position cannot be detected.

  Further, Patent Document 2 discloses a method in which a survey point is stored in a radio wave quality measurement device using a personal computer, and an investigator carries out a measurement work with a floor plan, and this method does not necessarily require GPS information. However, there is an inconvenience of having to carry out measurement work with a map.

In addition, upon receiving a cursor movement command from the manual operation panel and moving the cursor on the display, and receiving a measurement execution command from the manual operation panel, a measurement target at a measurement target position close to the current position of the cursor A measurement execution means for storing the radio wave intensity read from the radio wave intensity measurement unit in correspondence with the position data in the memory;
It has the structure characterized by comprising.

With the above configuration, the image data input means of the indoor wireless quality measuring device is used in advance to store the image data of the floor plan of the house to be measured for radio field intensity in the memory of the indoor wireless quality measuring device.
Next, when the user inputs a teaching mode selection command to the measurement position teaching means of the indoor wireless quality measuring device by operating a manual operation panel that functions as a man-machine interface, the mode of the indoor wireless quality measuring device is changed to the teaching mode. Then, the measurement position teaching means of the indoor wireless quality measuring device displays the image of the floor drawing of the house whose radio wave intensity is to be measured on the display based on the image data of the floor drawing stored in the memory.
Further, when the user inputs a cursor movement command by operating the manual operation panel of the indoor wireless quality measurement device, the measurement position teaching means of the quality measurement device detects the cursor movement command and moves the cursor on the display. The user moves the cursor to the measurement target position on the image where the radio field intensity is to be measured while referring to the floor plan of the house whose radio field intensity is to be measured, and operates the manual operation panel to the quality measurement device. Input measurement target position setting command. Upon receiving the measurement target position setting command, the measurement position teaching means of the quality measuring device detects the current position of the cursor and stores the position on the image corresponding to the current position of the cursor in the memory as measurement target position data.
Next, when the user visits the house whose radio field intensity is to be measured and operates the manual operation panel of the indoor wireless quality measurement device, and inputs a measurement mode selection command to the measurement execution means of the indoor wireless quality measurement device, the indoor wireless quality measurement The device mode switches to the measurement execution mode, and the measurement execution means displays the floor drawing image and the marker indicating the measurement target position on the display based on the floor drawing image data and the measurement target position data stored in the memory. To do.
The user moves inside the house with reference to the image of the floor plan of the house to be measured for radio wave intensity and the marker of the measurement target position on the image.
Then, the user who has reached the measurement target position operates the manual operation panel of the indoor wireless quality measurement device to move the cursor to the marker position on the image corresponding to his current position, that is, the measurement target position, and measures from the manual operation panel. When the execution command is input, the measurement execution unit stores the radio wave intensity read from the radio wave intensity measurement unit in the memory in association with the measurement target position data of the measurement target position close to the current position of the cursor.
Finally, the relationship between the measurement target position and the radio wave intensity stored in the memory of the indoor radio quality measurement device is loaded into a general-purpose radio quality analysis tool, and the measurement target position and radio wave intensity are processed by the radio quality analysis tool. Based on the relationship, the electric field strength distribution is created on the map or drawing.
Using the image data and the measured target position data of the floor plan stored in the memory of the indoor wireless quality measuring device displays a marker indicating the image and the measurement target position of the floor plan on a display of the indoor wireless quality measuring apparatus, and the image Since the user is guided to the measurement target position using the marker , the user can be appropriately guided to the measurement target position without carrying around a map or a drawing. In addition, the user who has moved to the measurement target position moves the cursor to the marker position on the image corresponding to the measurement target position, and inputs a measurement execution command from the manual operation panel. The radio wave intensity read from the radio wave intensity measurement unit is stored in the memory in association with the radio wave intensity measurement unit, so that the radio wave reception intensity can be accurately recorded in correspondence with the measurement position without using GPS position information. .

Alternatively, in place of the measurement execution means described above, a measurement mode selection command is received from the manual operation panel, and the floor drawing image data and the measurement target position data stored in the memory are displayed on the display . An image and a marker representing the measurement target position are displayed, and the cursor is moved on the display in response to a cursor movement command from the manual operation panel, and an image corresponding to the current position of the cursor each time the cursor is moved The upper position may be used as movement path point data, and a measurement execution unit may be provided for storing the movement path point data in the memory in association with the radio field intensity read from the radio field intensity measurement unit.

When such a configuration is applied, first, in the same manner as described above, the image data of the floor plan of the house whose radio wave intensity is to be measured is stored in the memory of the indoor wireless quality measuring device, and the image of the floor plan is displayed. After the measurement target position on the image for which the radio field intensity is to be measured is stored in the memory as the measurement target position data, the user visits the house where the radio field intensity is to be measured, and the floor stored in the memory Based on the image data of the drawing and the measurement target position data, an image of the floor drawing and a marker representing the measurement target position are displayed on the display.
Next, the user moves the interior of the house from the measurement target position to the measurement target position while referring to the image of the floor drawing of the house to be measured for radio field intensity and the marker representing the measurement target position on the image, and the indoor wireless The manual operation panel of the quality measuring device is operated to input a cursor movement command along the own movement locus, and the cursor is moved on the display by the measurement execution means of the quality measuring device.
Each time the cursor is moved, the measurement execution means uses the position on the image corresponding to the current position of the cursor as movement path point data, and associates the radio field intensity read from the radio field intensity measurement unit with the movement path point data. Store in memory.
Therefore, in addition to the measurement target position taught in advance, the radio wave intensity can be stored in the memory in association with each of several movement path points that interpolate between the measurement target position and the measurement target position.
Therefore, even if a general-purpose wireless quality analysis tool is not necessarily used, the electric field strength distribution can be created on the map or the drawing only by the function of the indoor wireless quality measuring device.

  In this case, the floor plan image read by the scanner, the floor plan image stored in the external memory, or the CAD data or draw data of the personal computer is rasterized and converted to GIF or BMP. It can be taken into the nonvolatile memory of the indoor wireless quality measuring device.

The indoor wireless quality measurement device of the present invention uses the floor plan image data and the measurement target position data stored in the memory of the indoor radio quality measurement device to display the floor plan image and the measurement target position on the display of the indoor radio quality measurement device. Since the marker representing this is displayed and the user is guided to the measurement target position using the image and the marker , the user can be guided to the measurement target position without carrying a map or a drawing.
In addition, the user who has moved to the measurement target position moves the cursor to the marker position on the image corresponding to the measurement target position, and inputs a measurement execution command from the manual operation panel. The radio wave intensity read from the radio wave intensity measurement unit is stored in the memory in association with the radio wave intensity measurement unit, so that the radio wave reception intensity can be accurately recorded in correspondence with the measurement position without using GPS position information. .

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view showing the appearance of a mobile phone according to an embodiment in which the function of the indoor wireless quality measuring apparatus of the present invention is mounted. FIG. 2 is a block diagram showing an outline of the configuration of the mobile phone according to the embodiment. It is.

  As shown in FIG. 1, the mobile phone 1 is a foldable mobile phone including a main housing 2 and a sub-housing 3, and has a microphone 4 and a man-machine interface on the side of the main housing 2. While having a functioning manual operation panel 5, a display 6 capable of graphic display, a speaker 7 and an antenna 8 are provided on the side of the sub-housing 3, and image data input is provided on the back side of the sub-housing 3. A CCD camera 9 that functions as a means is provided.

  The display 6 is composed of a liquid crystal monitor or the like, and is used for display of selection of telephone numbers, display of incoming call history, etc., display of mail in the process of creation and received mail, and the like, and normal use of the CCD camera 9 In the photographing mode, it is used for confirming an image captured by the CCD camera 9.

  The camera control unit 10 shown in FIG. 2 receives a command from the microprocessor 11 of the mobile phone 1 to drive the CCD camera 9, and the image captured by the CCD camera 9 is processed by the image processing unit 12 such as color correction. Is read into the microprocessor 11 and stored in the nonvolatile memory 13 of the mobile phone 1. In addition to image data, the non-volatile memory 13 stores mail text data, registered telephone numbers, e-mail addresses, and the like.

  As in the prior art, when the mobile phone 1 is used as a normal mobile communication terminal, the voice input from the microphone 4 is A / D converted by the voice processing unit 14 and transferred to the microprocessor 11. 11 is converted into communication format data, modulated by the transmission / reception unit 15 and transmitted to the outside via the telescopic antenna 8.

  The communication radio wave received by the antenna 8 is demodulated by the transmission / reception unit 15 and transferred to the microprocessor 11, converted into audio data, and then subjected to a processing operation such as D / A conversion by the audio processing unit 14. 7 is output as sound.

  The manual operation panel 5 includes a numeric keypad used for telephone number input operation and the like, and a cursor movement key for moving the cursor 16 up, down, left and right on the display 6, and further depends on the mode in which the mobile phone 1 is placed. Function keys for generating various commands, shooting execution keys, and the like. The above numeric keypad is also used as a kana key or the like for inputting text data when creating an e-mail.

  The radio wave intensity measuring unit 17 is used to measure the reception intensity of radio waves used for communication between the mobile phone 1 and the mobile phone base station, and is already known as a component of the mobile phone. The microprocessor 11 steadily samples the reception intensity of the radio wave detected by the radio field intensity measurement unit 17 and displays information such as the magnitude of the reception intensity and the out-of-service area in one corner of the display 6 in real time.

  In the ROM 18, in addition to a control program for executing processing required for transmission / reception of telephone calls and e-mails, as well as image capturing and image reproduction, in the present embodiment, the microprocessor 11 is used especially for indoor wireless communication. A control program for functioning as a measurement position teaching unit and a measurement execution unit of the quality measuring apparatus is stored.

  The card slot 19 is used for mounting an external memory such as an SD memory card, the input / output interface 20 is an interface for data input, and the RAM 21 temporarily stores data when the microprocessor 11 performs arithmetic processing. These are used for storage and are all known as components of mobile phones.

  As described above, the hardware configuration of the mobile phone 1 is the same as the conventional one.

  In this embodiment, the CCD camera 9 of the mobile phone 1 further functions as image data input means for inputting image data of the floor plan of the house, and the non-volatile memory 13 of the mobile phone 1 is an image of the floor plan. It functions as a memory for storing data.

  3 to 7 are flowcharts showing an outline of the processing operation of the microprocessor 11 when the mobile phone 1 is operated as an indoor wireless quality measuring device.

  Next, the processing operation of the microprocessor 11 functioning as a measurement position teaching unit and a measurement execution unit will be specifically described with reference to FIGS.

  In addition, as a floor plan of a house which is a measurement target of radio wave intensity, for example, a floor plan 22 (plan view) as shown in FIG. 11 is prepared in advance.

  The microprocessor 11 determines whether a drawing capture mode selection command is input by operating a function key of the manual operation panel 5 (step a1), and whether a teaching mode selection command is input by operating a function key of the manual operation panel 5 (step a1). a2), whether the measurement mode selection command is input by operating the function key of the manual operation panel 5 (step a3), and whether the monitor mode selection command is input by operating the function key of the manual operation panel 5 (step a4) If the input of these selection commands is not detected, only normal processing related to transmission / reception of telephone calls, creation of mail, transmission / reception, etc. is repeatedly executed in the same manner as before (step a5).

  Therefore, first, when a user who has prepared a floor plan 22 as shown in FIG. 11 operates a function key of the manual operation panel 5 to input a drawing capture mode selection command to the mobile phone 1, the microprocessor 11 performs step a1. In the determination process, the input of the drawing capture mode selection command is detected, and the process proceeds to the drawing capture mode process.

  The microprocessor 11 that has shifted to the process of the drawing capture mode first determines whether or not the shooting execution key of the manual operation panel 5 is operated (step a6), and if the operation of the shooting execution key is not detected, Further, it is determined whether or not an end key operation for returning to the normal process from the drawing capture mode is performed on the manual operation panel 5 (step a10). If no end key operation is detected, step a6 is performed. , Only the determination process of step a10 is repeatedly executed, and the user waits for the operation of the shooting execution key and the operation of the end key.

  Next, when the user points the lens of the CCD camera 9 toward the floor drawing 22 and operates the shooting execution key of the manual operation panel 5, the microprocessor 11 detects the operation of the shooting execution key in the determination process of step a6, and the CCD camera 9 Is activated to capture an image (step a7), and a standby state is waited for the user to set a drawing name for the floor drawing 22 (step a8).

  When the user operates the manual operation panel 5 to set a drawing name, the microprocessor 11 stores the drawing name in correspondence with the image captured in step a7 in the nonvolatile memory 13 (step a9).

  In the same manner as described above, the user repeatedly causes the microprocessor 11 to execute the processing of step a6 to step a9, thereby fetching a required number of floor plans and setting individual drawing names for each of the floor plans, thereby making it nonvolatile It can be stored in the memory 13.

  The user operates the end key of the manual operation panel 5 when the necessary number of floor drawings have been captured and the drawing name has been set, and declares the end of the drawing capture mode to the microprocessor 11.

  The microprocessor 11 detects the operation of the end key in the determination process of step a10, finishes the drawing capture mode process, and repeats only the determination process of steps a1 to a4 and the normal process of step a5. Return to the state.

  The process of storing the floor drawing in the nonvolatile memory 13 is not necessarily performed by operating the CCD camera 9. For example, the floor drawing image read by the scanner or the floor drawing image stored in the external memory, Furthermore, the CAD data, draw data, etc. of the personal computer are rasterized and the floor plan image converted into GIF or BMP is loaded into the nonvolatile memory 13 through the input / output interface 20 or the card slot 19 together with the drawing name. But it is feasible.

  Next, when the user inputs a teaching mode selection command to the microprocessor 11 by operating the function keys of the manual operation panel 5, the microprocessor 11 detects the input of the teaching mode selection command in the determination process of step a2, and the processing of the teaching mode is performed. Migrate to

  The microprocessor 11 that has shifted to the processing in the teaching mode first displays a list of drawing names stored in the nonvolatile memory 13 on the display 6 (step a11), and any one is operated by the operation of the manual operation panel 5 by the user. The system waits for selection of the drawing name (step a12).

  When the user operates the manual operation panel 5 to select one of the drawing names, the microprocessor 11 detects the drawing name selection operation in the determination process in step a12, and makes the number of call attempts, the call time, and the call interval. , And waits until the measurement conditions such as the transmission destination are input from the user by operating the manual operation panel 5 (step a13). When the measurement conditions are input, these measurement conditions are associated with the name of the selected drawing. It memorize | stores in the non-volatile memory 13 (step a14).

  Next, the microprocessor 11 functioning as the measurement position teaching means reads the image data of the floor drawing corresponding to the drawing name being selected from the nonvolatile memory 13, and for example, the cursor 16 is displayed on the display 6 as shown in FIG. And display it (step a15).

  Then, the microprocessor 11 determines whether or not the cursor movement key on the manual operation panel 5 has been operated (step a16). If the cursor movement key has not been operated, the plot command key on the manual operation panel 5 is further displayed. It is determined whether or not is operated (step a18). If the plot command key is not operated, it is further determined whether or not the end key of the manual operation panel 5 is operated (step a22). If any key is not operated, step a16, step Only the determination process of a18 and step a22 is repeatedly executed to wait for any key to be operated.

  Here, when the user operates the cursor movement key of the manual operation panel 5, the microprocessor 11 functioning as the measurement position teaching means detects the operation of the cursor movement key in the determination process of step a16, and responds to the operation of the cursor movement key. The cursor 16 is moved up, down, left and right on the display 6 (step a17).

  The user operates the cursor movement key on the manual operation panel 5 while referring to the floor drawing 22 of the house whose radio wave intensity is to be measured on the display 6, and moves the cursor 16 to the measurement target position on the image where the radio wave intensity is to be measured. After the movement, the plot command key on the manual operation panel 5 is operated to input a measurement target position setting command to the microprocessor 11.

  The microprocessor 11 functioning as the measurement position teaching means detects the input of the measurement target position setting command in the determination process of step a18, and selects the position on the image corresponding to the current position of the cursor 16 as the measurement target position data. The name is stored in the nonvolatile memory 13 in correspondence with the name (step a19), the measurement point marker is written in the image data itself in correspondence with the cursor position on the image (step a20), and the image in which the measurement point marker is written is written. The nonvolatile memory 13 is overwritten and stored (step a21).

  The set number of measurement target positions at which the radio field intensity is to be measured is arbitrary, and the user can cause the microprocessor 11 to repeatedly execute the processing of step a16 to step a21 in the same manner as described above, thereby providing the necessary number of measurement target positions. Data and measurement point markers can be stored in the nonvolatile memory 13 in association with the drawing name of the floor drawing being selected. FIG. 11 illustrates a case where four measurement point markers P1 (X1, Y1), P2 (X2, Y2), P3 (X3, Y3), and P4 (X4, Y4) are written on the floor drawing 22.

  The user stores the necessary number of measurement target position data and measurement point markers in the nonvolatile memory 13 by a teaching operation, and then operates the end key of the manual operation panel 5 to end the teaching mode to the microprocessor 11. Declare it against.

  The microprocessor 11 detects the operation of the end key in the determination process of step a22, finishes the teaching mode process, and enters an initial standby state in which only the determination process of steps a1 to a4 and the normal process of step a5 are repeatedly executed. Return.

  The work relating to the preparation of the floor drawing 22 and the capture of the image and the teaching of the measurement target position may be performed anywhere, but the floor drawing 22 should be brought when going to the house whose radio wave intensity is to be measured. Since it is cumbersome, it is desirable to complete the drawing capture mode and teaching mode processing before going to the house whose radio wave intensity is to be measured.

  Thereafter, the user goes to the house with which the mobile phone 1 is to be measured to measure the radio field intensity.

  When the user who arrives at the house to be measured inputs a measurement mode selection command to the microprocessor 11 by operating the function key of the manual operation panel 5, the microprocessor 11 outputs the measurement mode selection command in the determination process of step a3. Detect input and move to measurement mode processing.

  The microprocessor 11 having shifted to the measurement mode processing first displays a list of drawing names stored in the nonvolatile memory 13 on the display 6 (step a23), and any one is operated by the user operating the manual operation panel 5. The system waits for a drawing name to be selected (step a24).

  When the user operates the manual operation panel 5 to select a drawing name corresponding to the house whose radio wave intensity is to be measured, that is, the house currently in front of the user, the microprocessor 11 performs the determination process in step a24. The microprocessor 11 functioning as a measurement execution means detects the drawing name selection operation in FIG. 1 and reads out the floor plan image data corresponding to the selected drawing name from the non-volatile memory 13, for example, as shown in FIG. Then, the measurement point marker and the cursor 16 are displayed on the display 6 (step a25).

  Then, the microprocessor 11 reads the measurement conditions and measurement target position data stored in correspondence with the selected drawing name from the nonvolatile memory 13 (step a26), and the measurement start key on the manual operation panel 5 is operated. A standby state is awaited (step a27).

  Thereafter, when the user operates the measurement start key of the manual operation panel 5 to declare the start of measurement to the microprocessor 11, the microprocessor 11 detects the operation of the measurement start key in the determination process of step a27, and the process of step a26. The transmission / reception unit 15 is driven and controlled in accordance with the measurement conditions read out in (1) to start a call from the mobile phone 1 (step a28).

  Next, the microprocessor 11 determines whether or not the cursor movement key of the manual operation panel 5 is operated (step a29). If the cursor movement key is not operated, the microprocessor 11 further performs a measurement execution key. It is determined whether or not is operated (step a31). If the measurement execution key is not operated, it is further determined whether or not the end key of the manual operation panel 5 is operated (step a35). If any key is not operated, step a29 is executed. Only the determination process of a31 and step a35 is repeatedly executed to wait for any key to be operated.

  Here, when the user operates the cursor movement key of the manual operation panel 5, the microprocessor 11 functioning as the measurement execution means detects the operation of the cursor movement key in the determination process of step a29, and according to the operation of the cursor movement key. The cursor 16 is moved vertically and horizontally on the display 6 (step a30).

  The user moves the interior of the house while referring to the image of the floor drawing 22 of the house to be measured for radio wave intensity and the measurement point marker on the image on the display 6, so that any measurement target position, for example, FIG. 11 reaches one of the measurement target positions indicated by P1, P2, P3, and P4.

  Next, the user who has reached the measurement target position operates the manual operation panel 5 to move the cursor 16 to his / her current position, that is, a position on the image corresponding to one of the measurement target positions. The measurement execution command is input to the microprocessor 11.

  The microprocessor 11 functioning as the measurement execution means detects the input of the measurement execution command in the determination process in step a31, reads the current position of the cursor 16, and reads the current position of the cursor 16 in the process of step a26. It is determined whether or not the measurement target position data falls within the in-position range (step a32).

  If the current position of the cursor 16 is within the in-position width of any measurement target position data, the microprocessor 11 functioning as a measurement execution unit detects the radio wave currently detected by the radio wave intensity measuring unit 17. Is received (step a33), and the current radio wave reception intensity is stored in the nonvolatile memory 13 in correspondence with the measurement target position data at the position closest to the current position of the cursor 16 (step a34). For example, as shown in FIG. 11, even if the position of the cursor 16 to be adjusted to the position of the measurement target position P1 is shifted to the position of P1 ′, if the shift is within the in-position width range, the radio wave The reception intensity of the radio wave detected by the intensity measurement unit 17 at the present time is stored in the nonvolatile memory 13 corresponding to the measurement target position P1 of the floor drawing 22. However, the position of the cursor 16 does not represent the current position of the user itself as in the GPS information, but is merely a manual setting of the current position of the user that the user believes to be correct. Accordingly, the user appropriately determines the situation in the house and compares it with the image of the floor drawing 22 on the display 6, correctly moves to the original measurement target position, moves the cursor 16 to that position, and performs the measurement execution key. Need to operate.

  If the determination result at step a32 is false, it means that the measurement target position selection operation by the cursor 16 is extremely inaccurate, and therefore the processing from step a33 to step a34 is not executed. . In this case, the user needs to move the cursor 16 again by operating the cursor movement key, and position the cursor 16 in the vicinity of the measurement point marker representing the measurement target position.

  The user moves inside the house while referring to the image of the floor drawing 22 of the house to be measured for radio wave intensity and the measurement point marker on the image on the display 6, and moves to each of the measurement target positions taught in advance. In the same manner as described above, the microprocessor 11 repeatedly executes the processing operations of steps a29 to a34, and receives radio waves at all measurement target positions, for example, P1, P2, P3, and P4 in FIG. The intensity is measured, and these data are stored in the nonvolatile memory 13 in association with the drawing name and the measurement target position data, and then the end key of the manual operation panel 5 is operated to end the measurement mode. Declare against

  The microprocessor 11 detects the operation of the end key in the determination process of step a35, finishes the measurement mode process, and enters an initial standby state in which only the determination process of steps a1 to a4 and the normal process of step a5 are repeatedly executed. Return.

Finally, the relationship between the measurement target position data for each drawing name stored in the nonvolatile memory 13 of the mobile phone 1 and the radio wave intensity, for example, stored in correspondence with the floor drawing 22 (measurement position P1, radio wave) SD memory card in which intensity S1), (measurement position P2, radio wave intensity S2), (measurement position P3, radio wave intensity S3), (measurement position P4, radio wave intensity S4), etc. are connected to the input / output interface 20 or the card slot 19 Etc., and is read by a general-purpose wireless quality analysis tool, and in the same manner as in the past, in the processing on the wireless quality analysis tool side, on the floor drawing 22 or other drawings based on the relationship between the measurement target position and the radio wave intensity To create an electric field strength distribution.
Alternatively, the general-purpose wireless quality analysis tool may be made to read the relationship between the measurement target position data and the radio wave intensity for each drawing name using the packet communication function of the mobile phone 1.

  In the mobile phone 1 of this embodiment, it is possible to check the correspondence between the measurement target position data and the radio wave intensity using only the mobile phone 1.

  When the correspondence relationship between the measurement target position data and the radio wave intensity is confirmed on the mobile phone 1, the user inputs a monitor mode selection command to the microprocessor 11 by operating a function key of the manual operation panel 5.

  The microprocessor 11 detects the input of the monitor mode selection command in the determination process of step a4, and shifts to the monitor mode process.

  The microprocessor 11 having shifted to the monitor mode processing first displays a list of drawing names stored in the nonvolatile memory 13 on the display 6 (step a36), and any one is operated by the user operating the manual operation panel 5. The system waits for selection of the drawing name (step a37).

  When the user operates the manual operation panel 5 and selects the drawing name of the floor drawing corresponding to the house for which the correspondence between the measurement target position data and the radio wave intensity is to be confirmed, the microprocessor 11 performs the determination process in step a37. , The drawing name selection operation is detected, and the floor drawing image data corresponding to the selected drawing name and the measurement target position data stored corresponding to the selected drawing name are read from the nonvolatile memory 13, and the floor is read. The image of the drawing is displayed on the display 6 together with the measurement point marker and the cursor 16 (step a38).

  Next, the microprocessor 11 determines whether or not the cursor movement key on the manual operation panel 5 is operated (step a39). If the cursor movement key is not operated, an end key on the manual operation panel 5 is further displayed. It is determined whether or not it is operated (step a43). If any key is not operated, only the determination processing of step a39 and step a43 is repeatedly executed, and waiting for any key to be operated. To do.

  Here, when the user operates the cursor movement key of the manual operation panel 5, the microprocessor 11 detects the operation of the cursor movement key in the determination process of step a39, and the cursor 16 is displayed on the display 6 in accordance with the operation of the cursor movement key. Is moved up, down, left and right (step a40), and each time the cursor 16 is moved, is the current position of the cursor 16 within the in-position width of any measurement target position data read out in the process of step a38? It is determined whether or not (step a41).

  If the current position of the cursor 16 is within the in-position width of any measurement target position data, the microprocessor 11 stores the radio wave intensity data stored corresponding to the measurement target position data in a nonvolatile manner. Read out from the memory 13 and displayed as numerical information on the display 6 (step a42).

  The user moves the cursor 16 to various positions on the display 6 so that the measurement value of the radio wave intensity corresponding to the measurement target position data at the position closest to the current cursor position is displayed on the display 6 and appropriately referred to. Is possible.

  When the user operates the end key of the manual operation panel 5, the microprocessor 11 detects the operation of the end key in the determination process in step a43, finishes the monitor mode process, and performs the determination process in steps a1 to a4. It returns to the initial standby state in which only the normal processing of step a5 is repeatedly executed.

  As described above, in this embodiment, the image data of the floor plan 22 of the house whose radio wave intensity is to be measured and the measurement target position data set by the teaching operation are stored in advance in the nonvolatile memory 13 of the mobile phone 1. The user who goes to the house whose radio wave intensity is to be measured with the mobile phone 1 is appropriately displayed using the image of the floor drawing 22 displayed on the display 6 of the mobile phone 1 and the measurement point marker indicating the measurement target position. Therefore, the user can accurately reach the measurement target position without carrying around a map or a drawing.

  In addition, when the user who has moved to the measurement target position moves the cursor 16 to a position on the image corresponding to the measurement target position and inputs a measurement execution command from the manual operation panel 5, the measurement close to the current position of the cursor 16 is performed. Since the target position and the radio field intensity read from the radio field intensity measurement unit 17 are associated with each other and stored in the nonvolatile memory 13, the target position is associated with a predetermined measurement position without using the GPS position information. Radio wave reception intensity can be recorded accurately.

  Next, the image data of the floor plan of the house and the measurement target position data stored in the nonvolatile memory 13 when the user visits the house to be measured for radio field intensity are displayed on the display 6. The cursor 16 is moved on the display 6 in response to an input of a cursor movement command from the manual operation panel 5, and each time the cursor 16 is moved, the position on the image corresponding to the current position of the cursor 16 is nonvolatile as movement path point data. The mobile phone (indoor wireless quality measuring device) 1 is stored in the memory 13 and further stores the radio wave intensity read from the radio wave intensity measuring unit 17 in the nonvolatile memory 13 in correspondence with the movement path point data. The embodiment will be briefly described.

  The hardware configuration of the mobile phone 1 is the same as that of the above-described embodiment. Further, the operations and processing operations related to the preparation of the floor drawing 22 and the capture of the image and the teaching of the measurement target position are the same as the processing of step a1 to step a10 in the above-described embodiment. Is omitted.

  8 to 10 are flowcharts showing the processing operation of the microprocessor 11 functioning as the measurement position teaching unit and the measurement execution unit in the present embodiment.

  When the user inputs a teaching mode selection command to the microprocessor 11 by operating the function keys on the manual operation panel 5, the microprocessor 11 detects the input of the teaching mode selection command in the same manner as in the above-described embodiment, and the teaching mode is selected. Move on to processing.

  The microprocessor 11 that has shifted to the processing in the teaching mode displays a list of drawing names stored in the nonvolatile memory 13 on the display 6 (step b1), and any drawing is operated by the user operating the manual operation panel 5. A standby state is waited for until a name is selected (step b2).

  When the user operates the manual operation panel 5 to select any drawing name, the microprocessor 11 detects the drawing name selection operation in the determination process in step b2, and makes the number of call attempts, the call time, and the call interval. , And waits until the measurement conditions such as the transmission destination are input from the user by operating the manual operation panel 5 (step b3). When the measurement conditions are input, these measurement conditions are associated with the selected drawing name. It memorize | stores in the non-volatile memory 13 (step b4).

  Next, the microprocessor 11 functioning as the measurement position teaching means reads the image data of the floor drawing corresponding to the drawing name being selected from the nonvolatile memory 13, and for example, the cursor 16 is displayed on the display 6 as shown in FIG. And display it (step b5).

  Then, the microprocessor 11 determines whether or not the cursor movement key on the manual operation panel 5 has been operated (step b6). If the cursor movement key has not been operated, the plot command key on the manual operation panel 5 is further displayed. It is determined whether or not is operated (step b8). If the plot command key has not been operated, it is further determined whether or not the end key of the manual operation panel 5 has been operated (step b11). Only the determination process of b8 and step b11 is repeatedly executed to wait for any key to be operated.

  Here, when the user operates the cursor movement key of the manual operation panel 5, the microprocessor 11 functioning as the measurement position teaching means detects the operation of the cursor movement key in the determination process of step b6, and responds to the operation of the cursor movement key. The cursor 16 is moved up, down, left and right on the display 6 (step b7).

  The user operates the cursor movement key on the manual operation panel 5 while referring to the floor drawing 22 of the house whose radio wave intensity is to be measured on the display 6, and moves the cursor 16 to the measurement target position on the image where the radio wave intensity is to be measured. After the movement, the plot command key on the manual operation panel 5 is operated to input a measurement target position setting command to the microprocessor 11.

  The microprocessor 11 functioning as the measurement position teaching means detects the input of the measurement target position setting command in the determination process in step b8, and writes the measurement point marker in the image data itself in correspondence with the cursor position on the image (step b9). ), The image in which the measurement point marker is written is overwritten and stored in the nonvolatile memory 13 (step b10).

  The difference from the above-described embodiment is that only the measurement point marker is written in the image data itself in correspondence with the cursor position on the image, and it is not necessary to store the measurement target position data in the nonvolatile memory 13 as a numerical value. is there. The measurement point marker recorded on the image is a part of the image data and is not stored in the nonvolatile memory 13 as data having numerical values, but is measurement target position data in a broad sense.

  The user writes the required number of measurement point markers in the selected floor drawing and stores them in the non-volatile memory 13 by causing the microprocessor 11 to repeatedly execute the processing of step b6 to step b10 in the same manner as described above. Can do. FIG. 11 illustrates a case where four measurement point markers P1 (X1, Y1), P2 (X2, Y2), P3 (X3, Y3), and P4 (X4, Y4) are written on the floor drawing 22.

  The user writes the required number of measurement point markers on the floor drawing being selected by the teaching operation and stores it in the non-volatile memory 13, and then operates the end key of the manual operation panel 5 to make the end of the teaching mode microscopic. The microprocessor 11 that has declared to the processor 11 and detected the end key operation in the determination process in step b11 ends the teaching mode process, and repeats only the determination process in steps a1 to a4 and the normal process in step a5. Return to the initial standby state to execute.

  Thereafter, the user goes to the house with which the mobile phone 1 is to be measured to measure the radio field intensity.

  When the user who arrives at the house to be measured inputs a measurement mode selection command to the microprocessor 11 by operating the function key of the manual operation panel 5, the microprocessor 11 outputs the measurement mode selection command in the determination process of step a3. Detect input and move to measurement mode processing.

  The microprocessor 11 having shifted to the measurement mode process first displays a list of drawing names stored in the nonvolatile memory 13 on the display 6 (step b12), and any one is operated by the user operating the manual operation panel 5. A standby state is entered in which the drawing name is selected (step b13).

  Then, when the user operates the manual operation panel 5 to select a house whose radio field intensity is to be measured, that is, a drawing name corresponding to the house currently in front of the user, the microprocessor 11 performs the determination process in step b13. The microprocessor 11 functioning as a measurement execution means detects the drawing name selection operation in FIG. 1 and reads out the floor plan image data corresponding to the selected drawing name from the non-volatile memory 13, for example, as shown in FIG. Then, the measurement point marker and the cursor 16 are displayed on the display 6 (step b14).

  Then, the microprocessor 11 reads the measurement conditions and measurement target position data stored in correspondence with the selected drawing name from the nonvolatile memory 13 (step b15), and the measurement start key on the manual operation panel 5 is operated. A standby state for waiting is entered (step b16).

  Thereafter, when the user operates the measurement start key of the manual operation panel 5 to declare the start of measurement to the microprocessor 11, the microprocessor 11 detects the operation of the measurement start key in the determination process of step b16, and the process of step b15 The transmission / reception unit 15 is driven and controlled in accordance with the measurement conditions read out in (1), and a call from the mobile phone 1 is started (step b17).

  Next, the microprocessor 11 determines whether or not the cursor movement key of the manual operation panel 5 has been operated (step b18). If the cursor movement key has not been operated, the measurement execution instructing execution of measurement is further performed. It is determined whether or not the flag F is set (step b21). If the measurement execution flag F is not set, it is further determined whether or not the end key of the manual operation panel 5 is operated (step b27). If any key is not operated, step b18, Only the determination process of step b21 and step b27 is repeatedly executed, and it waits for any key to be operated.

  The user refers to the image of the floor drawing 22 of the house to be measured for the radio wave intensity and the measurement point marker on the image on the display 6 and communicates the measurement target position, for example, P1, in FIG. It moves slowly along the path connecting P2, P3 and P4, and each time the cursor movement key on the manual operation panel 5 is operated, the cursor 16 is moved on the display 6 along its own movement path.

  The operation of the cursor movement key is detected by the determination process in step b18, and the microprocessor 11 functioning as a measurement execution unit moves the cursor 16 up, down, left and right on the display 6 in accordance with the operation of the cursor movement key (step b19). In each case, a measurement execution flag F for instructing execution of the measurement is set (step b20).

  When the determination processing in step b21 confirms that the measurement execution flag F is set in accordance with the operation of the cursor movement key, that is, the movement of the cursor 16, the microprocessor 11 functioning as the measurement execution means measures the radio field intensity at the present time. The reception intensity of the radio wave detected by the unit 17 is read (step b22), and the position on the floor drawing corresponding to the current position of the cursor 16 is set as the movement path point data. Are stored in the non-volatile memory 13 (step b23), a path marker is written in the image data itself in correspondence with the cursor position on the image (step b24), and the image in which the path marker is written is non-volatile. After overwriting and storing in the memory 13 (step b25), the measurement execution flag F is set. And set (step b26), step b18, step b21, enters a standby state repeatedly executes the determination processing only in step b27.

  When the movement of the cursor 16 due to the operation of the cursor movement key is detected and the measurement execution flag F is set, the processing from step b22 to step b25 is repeatedly executed, so that the measurement target positions P1, P2, P3, and P4 are connected. The non-volatile memory 13 can store the radio wave intensity corresponding to each of several movement path points in such a manner that the path is interpolated at an appropriate interval according to the operation of the cursor movement key.

  However, as in the first embodiment, the position of the cursor 16 does not represent the user's current position itself like GPS information. Since it is only set by the operation, the user appropriately determines the situation in the house, compares it with the image of the floor drawing 22 on the display 6, and communicates the original measurement target position along the route. It is necessary to move the cursor 16 accurately on the display 6 along its own movement path by operating the cursor movement key of the manual operation panel 5 each time. Alternatively, an electronic compass and an acceleration sensor may be additionally provided in the mobile phone 1 so that the movement path of the mobile phone 1 is automatically detected and the cursor 16 is moved on the display 6. In that case, in the process of step b18 When operating the measurement start key, the user holds the mobile phone 1 and moves to one of the measurement points, for example, P1, and moves the cursor 16 to the P1 position of the image on the display 6 to control the zero point of the coordinate system of the mobile phone 1. After starting, the electronic compass and the acceleration sensor are started, and instead of the processing of step b18 to step b21, the reading of the moving position of the mobile phone 1 with the zero point restricted position, for example, P1 as the origin, and the moving position of the cursor 16 are performed. Update display is performed, and the processing of step b22 to step b25 is performed every predetermined sampling period, or The displacement of the band phone 1 is so repeatedly executed each time exceeding the threshold value e.g. 1-meter predetermined.

  The user who has finished measuring the radio field intensity operates the end key of the manual operation panel 5 to declare the end of the measurement mode to the microprocessor 11 and detects the operation of the end key in the determination process of step b27. Returns to the initial standby state in which the measurement mode process is ended and only the determination process of steps a1 to a4 and the normal process of step a5 are repeatedly executed.

Finally, an SD memory card or a mobile phone connected to the input / output interface 20 or the card slot 19 shows the relationship between the movement path point data for each drawing name stored in the nonvolatile memory 13 of the mobile phone 1 and the radio wave intensity. 1 is loaded into a general-purpose wireless quality analysis tool using the packet communication function of 1 and is processed on the floor drawing 22 based on the relationship between the measurement target position and the radio wave intensity in the same manner as in the past. Alternatively, an electric field strength distribution is created on another drawing.
Compared with the above-described embodiment, the measurement position where the radio field intensity is measured, that is, the movement path point is denser, so that a strict electric field intensity distribution can be created. Alternatively, it is also possible to create an electric field strength distribution using the measurement value itself by utilizing the fact that the measurement positions where the radio field intensity is measured are dense.

  In the mobile phone 1 of this embodiment, it is possible to check the correspondence between the position data of the movement path point and the radio wave intensity using only the mobile phone 1.

  When confirming the correspondence between the position data of the movement path point and the radio wave intensity on the mobile phone 1, the user inputs a monitor mode selection command to the microprocessor 11 by operating the function key of the manual operation panel 5.

  The microprocessor 11 detects the input of the monitor mode selection command in the determination process of step a4, and shifts to the monitor mode process.

  The microprocessor 11 having shifted to the monitor mode processing first displays a list of drawing names stored in the nonvolatile memory 13 on the display 6 (step b28), and any one is operated by the user operating the manual operation panel 5. The system waits for selection of the drawing name (step b29).

  Then, when the user operates the manual operation panel 5 and selects the drawing name of the floor drawing corresponding to the house for which the correspondence between the position data of the movement path point and the radio wave intensity is to be confirmed, the microprocessor 11 performs step b29. The selection operation of the drawing name is detected in the determination process, and the image data of the floor drawing corresponding to the drawing name being selected and the position data of the movement path point stored corresponding to the drawing name being selected are stored from the nonvolatile memory 13. The data is read out and the floor plan image is displayed on the display 6 together with the route marker and the cursor 16 (step b30).

  Next, the microprocessor 11 determines whether or not the cursor movement key on the manual operation panel 5 is operated (step b31). If the cursor movement key is not operated, an end key on the manual operation panel 5 is further displayed. It is determined whether or not it is operated (step b35). If any key is not operated, only the determination process of step b31 and step b35 is repeatedly executed, and waiting for any key to be operated. To do.

  Here, when the user operates the cursor movement key of the manual operation panel 5, the microprocessor 11 detects the operation of the cursor movement key in the determination process of step b31, and the cursor 16 is displayed on the display 6 according to the operation of the cursor movement key. Is moved up, down, left and right (step b32), and each time the cursor 16 moves, whether or not there is a path marker at any of the movement path points read out in the process of step b30 in the vicinity of the current position of the cursor 16. Is determined (step b33).

  If there is a path marker of any movement path point in the vicinity of the current position of the cursor 16, the microprocessor 11 stores the radio wave intensity data stored corresponding to the position data of the movement path point in a nonvolatile manner. Is read out from the memory 13 and displayed as numerical information on the display 6 (step b34).

  The user moves the cursor 16 to various positions on the display 6 so that the measured value of the radio wave intensity corresponding to the position data of the moving path point closest to the current cursor position is displayed on the display 6 and appropriately referred to. Is possible.

  When the user operates the end key of the manual operation panel 5, the microprocessor 11 detects the operation of the end key in the determination process in step b35, finishes the monitor mode process, and performs the determination process in steps a1 to a4. It returns to the initial standby state in which only the normal processing of step a5 is repeatedly executed.

  As described above, in this embodiment, the mobile phone in which the measurement point marker is written to the image data of the floor plan 22 of the house whose radio wave intensity is to be measured by the teaching operation and the image data is stored in the nonvolatile memory 13. A user who goes to the house whose radio wave intensity is to be measured with 1 is guided to an appropriate measurement target position by an image of the floor drawing 22 displayed on the display 6 of the mobile phone 1 and a measurement point marker indicating the measurement target position. Therefore, the user can accurately grasp the measurement target position without carrying around a map or a drawing.

  In actual measurement, the manual operation panel 5 of the mobile phone 1 is operated to move the cursor 16 on the display 6 along the user's movement trajectory. Since the radio field intensity is stored in the nonvolatile memory 13 in correspondence with the current position, the route connecting the measurement target positions can be set at an appropriate interval according to the operation of the cursor movement key without using the GPS position information. It is possible to store the radio wave intensity corresponding to each of several moving path points in such a manner as to be interpolated by.

  In any of the embodiments, the function of the indoor wireless quality measurement device is incorporated using the configuration of a general mobile phone, so that it is not necessary to add a special structure and implement the development cost. This is advantageous in terms of reducing manufacturing costs. Further, since the microprocessor 11 of the mobile phone 1 is configured to control the call and the radio wave intensity measuring unit 17, it is different from a conventional indoor wireless quality measuring device that uses the mobile phone 1 as a mere call means. The reception intensity can be measured without using a general-purpose personal computer or a special radio wave intensity measuring device that controls the mobile phone serving as a calling means, and a small and lightweight measuring device can be obtained.

  Further, since the image of the floor plan of the house to be measured is taken into the non-volatile memory 13 using the CCD camera 9 of the mobile phone 1 or the like, the floor plan image is displayed on the display 6. Even when a public map service or the like cannot be used, the reception intensity of radio waves in the house can be easily measured.

  Moreover, the image of the floor plan and the cursor 16 are simultaneously displayed on the display 6 of the mobile phone 1, and the reception intensity of the radio wave is stored in correspondence with the measurement position by moving the cursor 16 and specifying the position on the image. Therefore, even in an indoor place where GPS signals are difficult to reach, it is possible to store the measurement position and the measurement result in correspondence with each other.

  In addition, the measurement data stored in the nonvolatile memory 13 of the mobile phone 1 is transferred to the packet communication of the mobile phone 1 or through an external memory such as an SD memory card that is detachably attached to the input / output interface 20 and the card slot 20. Since data can be output, data can be easily taken into a general-purpose wireless quality analysis tool.
