Description

  This invention is a room dimension measuring device for measuring the dimensions of a room when cutting tatami mats, carpets, etc. in accordance with the shape of the room, and expressing the dimensions for cutting by numerical control, etc. Based on polar coordinate data consisting of length data and angle data to the measurement points around the room, measured based on the position near the center of the rectangular room, the room dimensions are determined and converted to data suitable for cutting. It is related with the dimension measurement apparatus of the room for describing.

  When laying tatami mats or carpets in the room, the actual area of the room is not always the same. Therefore, before construction, the actual dimensions of the room are measured in advance, and the room Cutting tatami mats and carpets according to the shape.

  In particular, when tatami mats are laid, they are allocated to 6 tatami mats, 8 tatami mats, 12 tatami mats, and the like, and the dimensions of the room to be measured in this case are, for example, five hundred eight (5 scale 8). From the standard dimensions of the room determined by the standard size of the tatami mat and the number of tatami mats, such as dimensions x 2 scales 9 dimensions), Sanroku (6 scales x 3 scales), Honma (6 scales 3 dimensions x 3 scales 1 dimension 5 minutes) It is normally performed to express the deviation of

  And, as a measurement method that represents the dimensions of the room by such deviation from the reference dimension, the room dimensions are usually taken with the “medium measurement method” in which the number of measurement points is small and the measurement time is short. In the surrounding sills and the like, particularly in locations where the distortion is particularly large, a method of measuring the dimensions more finely by the “medium booth measurement method” is generally used.

  As a dimensional measuring apparatus for such a room, a base, a turntable that is rotatably mounted on the base, and a rotary that is placed on the turntable and detects the rotation angle of the turntable with respect to the base -An encoder, a linear encoder that is placed on a turntable, winds up a wire or tape, and detects the length of the drawn wire or tape, etc., and a turntable placed on the turntable A laser light source that emits a laser beam in the directivity direction, a probe having a sharp tip coupled to the tip of a wire or a tape, and a laser beam provided on the probe when receiving the laser beam. A response device that re-radiates and a storage device that stores the angle data and length data when the light beam is re-radiated from the response device by aligning the tip of the probe with the reference point to be measured existing in the pointing direction Apparatus comprising bets have been proposed in the following patent document 1.

  Since the room is usually a quadrangle, the angle formed by the two measured line segments is limited to “near 0 degree” or “near right angle (90 degrees)”. Therefore, it can be determined that the angle is 90 degrees or less, and it is a point on the side of the room when the angle is 90 degrees or more, and the measurement point is a measurement point that represents the "room corner". It can be easily determined whether or not.

  Therefore, in the measurement of a room with a center pillar or corner pillar, it is possible to measure the place of the place that cannot be measured, and to calculate the dimensions of the corner pillar and the middle pillar to be measured in a pseudo manner by calculation. There is a proposal of a room size notation method based on a calculation method by this method in Patent Document 2 below.

Install and use additional dedicated software.

  As shown in the block diagram of FIG. 2, the mobile terminal device 3 includes a Bluetooth wireless communication unit 31, a display unit 32, an operation unit 33, a storage unit 34, a main calculation unit, which communicate with the measurement apparatus main body. 35 and.

  The display unit 32 and the operation unit 33 of the mobile terminal device 3 are on the same screen and are used as a touch panel. The “initial setting screen” (FIG. 6) and the “origin setting screen” for setting the polar coordinate origin ( Fig. 7) is provided with a "measurement screen" (Fig. 8) that displays measurement procedure input and measurement progress, and the "measurement screen" includes measurements to be measured in each room set on the initial setting screen. It also has a screen that displays points and displays the progress of measurement. Further, instead of the mobile terminal device having a touch panel, display and operation can be performed in the same manner by using a conventional mobile phone having a keypad such as a numeric keypad and a display screen separately.

  Further, when the measurement is completed on the “measurement screen” in FIG. 8, a “measurement completion screen” (FIG. 9) is displayed. In this “measurement completion screen”, the information input on the “initial setting screen” and the deviation (habit) at each measurement point are displayed around the mat.

  The size of the room is expressed by the number of tatami mats: 1 tatami mat, 2 tatami mats, 4 tatami mats, 4 tatami mats, 6 tatami mats, 7 tatami mats, 8 tatami mats, 10 tatami mats, 12 tatami mats, 12 tatami mats, 15 tatami mats. , 18 tatami mats, and so on. In addition, the standards of the size of the tatami mats to be laid out include Goha (long side is 5 scales, 8 inches), Sanroku (long side is 6 scales), and Honma (long sides are 6 scales, 3 dimensions).

  When measuring the dimensions of a room, a 6 tatami room will be described as an example. As shown in FIG. 3A, the distance between measurement points is determined based on the length of the short side of the tatami mat. In addition to the measurement points of the “intermediate measurement method” and the measurement points of the intermediate measurement method, determine the interval by adding measurement points using the length of one-fourth of the long side of the tatami in contact with the threshold as a guideline. The “booth measuring method” shown in (b) is adopted.

  As shown in FIG. 6, in the “initial setting screen” of the mobile terminal device 3, in addition to the room number, the standard of tatami mats to be laid, the size of the room represented by the number of tatami mats, the direction of the room, the thickness of the tatami mat, A customer name, a place name, a room name, etc. are input as site information (step 1 in the flowchart of FIG. 4).

  Further, the “initial setting screen” includes a touch unit that performs operations such as measurement, data transmission, setting completion, and termination.

  As shown in FIG. 7, the “screen for setting the origin of polar coordinates” is provided with a touch unit for performing the operation of “origin setting”, and as shown in FIG. , The direction of radiation of the visible laser beam 15 emitted from the laser light source 5 is directed slightly in the direction opposite to the rotation direction from the first measurement point (● mark), the probe is hooked on the main body and the wire is If it is confirmed that it has not been pulled out, the touch unit for setting the origin shown in FIG. 7 is touched (step 2).

  When the origin setting touch part is touched, the count values of the rotary encoder 11 and the linear encoder 13 in the signal processing circuit of the main body are reset to 0, the initial setting of the measurement is completed (step 3), Move to the measurement screen shown in FIG. 8 (step 4).

  The “measurement screen” for displaying the measurement procedure is such that the measurer holds the portable terminal device 3 with one hand, removes the probe 4 from the main body H with the other hand, stretches the wire, and sharpens the tip 41 of the probe 4. To the first measurement point (marked with ●).

  When the measurer touches “Driving” on the “Measurement screen” (Step 5), the measuring apparatus main body H rotates the turntable 1 in the clockwise direction while irradiating the laser beam 15. During this rotation, when the laser beam 15 crosses the probe 4, the laser beam 15 is incident on the optical sensor 42 of the probe 4, so that infrared light is emitted from the response LED 43 at the moment when the laser beam 15 is incident. When the measurement device body responds to the measurement device body by re-radiating in the incident direction, the measurement device body uses the Bluetooth wireless communication unit 10 to transmit the angle data and length data counted by the rotary encoder 11 and the linear encoder 13 to the portable terminal. Transmit to device 3.

  The portable terminal device 3 stores the angle data and length data of the first measurement point received from the measurement device main body in the storage unit 34, converts the data into polar coordinate data, and displays the corresponding data displayed on the “measurement screen”. Fill the circles at the measurement points in the room (Step 6).

  Then, the mobile terminal device 3 determines whether or not the current measurement point is the last measurement point (step 7). If it is not at the last measurement point, the process returns to step 4.

  When the measurer aligns the tip 41 of the probe 4 with the second measurement point on the right side and touches and touches “Driving” on the “Measurement screen” again (step 5), the turntable 1 rotates, When the laser beam 15 crosses the probe 4 waiting at the next measurement point, the laser beam 15 is incident on the optical sensor 42 of the probe 4. Re-radiate in the incident direction.

  In the turntable 1, the angle data and length counted by the up / down counter 18 and the up / down counter 19 at the moment when the second re-radiated infrared ray is received by the optical sensor 16 of the turntable 1. Data is transmitted to the mobile terminal device 3 by the Bluetooth wireless communication unit 10. (Step 5).

  The portable terminal device 3 stores the angle data and length data of the second measurement point received from the measurement device main body H in the storage unit 34, converts the data into polar coordinate data, and displays the correspondence displayed on the “measurement screen”. The circles of the second measurement points of the room to be filled are filled (step 6). Then, the mobile terminal device 3 determines whether or not the current measurement point is the last measurement point (step 7).

  When the operations of Step 4 to Step 7 are repeated, the circles of the measured measurement points are sequentially painted and displayed, so that the progress status can be grasped. In the case of 6 tatami mats, the data is collected 14 times, and in the case of booth measurements, the data is collected 24 times and the data collection is terminated.

  Data collected at each measurement point is sequentially subjected to polar coordinate calculation by the main calculation unit and stored in the storage unit of the mobile terminal device 3. When the data collection is completed, the data is converted into XY coordinate system data. Note that all data at all measurement points may be collected and then converted into XY coordinate system data.

  Then, the measurement result based on the collected data is displayed on the “measurement completion screen” shown in FIG. 9 together with the initially set information.

(Second Embodiment)
In the first embodiment described above, the distance from the measuring device main body installed at the origin to each measuring point is converted from the length of the wire or tape drawn from the measuring device main body into length data by the linear encoder. However, the same operation can be performed even if the distance from the measurement apparatus main body to each measurement point is measured by a laser distance meter.

  As disclosed in Japanese Patent No. 4061414 and Japanese Patent No. 4178289, a laser rangefinder is mounted on the measurement apparatus main body instead of a linear encoder and a wire or tape.

  As in the first embodiment, when the measuring apparatus main body is rotated while operating the laser distance meter, the laser beam of the laser distance meter also rotates, and the irradiation position can be confirmed visually.

  Therefore, when the laser beam irradiates a predetermined measurement point, the mobile terminal device is operated to transmit an electrical signal instructing data capture to the measurement device body, and the angle data and laser distance obtained by the rotary encoder By configuring the length data obtained by the total to be transmitted to the mobile terminal device, it is possible to collect data in polar coordinates as well.

(Third embodiment)
After collecting the angle data and length data from approximately the center of the room to a plurality of measurement points around the room by the room dimension measuring device described in the first or second embodiment, the floor of the room at each measurement point It is configured to collect height data from the surface to the top of the sill.

  When a plurality of tatami mats are laid in a room, if the surface heights of adjacent tatami mats do not match, a step is produced at the mating portion of the tatami mats. In particular, in the tatami mat that touches the sill, if the upper surface of the sill does not coincide with the surface height of the tatami mat, a step is similarly generated in the abutting portion and the appearance is deteriorated.

  Therefore, in order to align the surface height of the mating part of the tatami mat and the sill without a step, in the manufacturing process, a spacer is inserted on the back surface of the mating part with the tatami sill for each tatami mat to make the tatami thickness fine. Adjustment has been made conventionally.

  When laying tatami in the room, measure the height from the floor surface to the top of the sill at each important point around the room separately and write it down. The thickness of the abutting part (bottom front, heel) was finely adjusted.

  As the sill height measuring device, as shown in the perspective view of FIG. 10, a device having a photodiode array 71 provided in front of a semi-cylindrical height measuring device 7 having a handle 79 is used. The handle 79 is also used as a dry battery case, and includes a switch 77.

  As shown in the block diagram of FIG. 11, the threshold height measuring device 7 includes a photodiode array 71, a multiplexer 72 to which each output channel of the photodiode array 71 is connected, and a multiplexer 72. A / D conversion circuit 74 for A / D converting the output of one selectively connected channel, microcomputer 75, and Bluetooth (registered trademark) for transmitting height data output from the serial communication port of microcomputer 75 ) A wireless communication unit 76 is provided.

  In the multiplexer 72, address signals that change sequentially from the microcomputer 75 are applied to the address terminals 73, and one of the output channels of the photodiode array 71 is sequentially led to the A / D conversion circuit 74. Therefore, the photodiode array 71 operates to scan in the vertical direction.

  When measuring the height of the sill 9, touching the “sill height” on the screen shown in FIG. 13, an oval frame for entering the sill height data is also written for each measurement point. The

  At this time, the number of measurement points is determined based on “room size” and “measurement method (intermediate measurement method, booth measurement method)” set in advance on the “initial setting screen” shown in FIG.

  Then, for each measurement point, as shown in the perspective view of FIG. 12, the sill height measuring device 7 is placed on the floor surface, and the surface having the photodiode array 71 is pressed against the side surface of the sill 9 to switch 77. When the power is turned on by operating, the measurement operation starts.

  When the photodiode array 71 is scanned, in the lower photodiode array 71a, the incident light is blocked by the threshold 9 and is dark, and the output level is low. However, in the photodiode array 71b above the upper surface of the sill, the output level becomes high because external light is incident.

  When measuring the height of the sill in a dark place, the incident external light is weak and difficult to measure. Therefore, an LED is provided on the photodiode array 71 and is lit during measurement. It is convenient to keep it.

  When the digital signal of incident light output from the A / D conversion circuit 73 changes suddenly during scanning, the address signal applied to the multiplexer 72 corresponds to the address of the photodiode 71 directed to the top surface of the sill. doing. Therefore, the address when the digital signal suddenly changes corresponds to the height of the threshold 9.

  The address of the multiplexer 72 is converted into height data by the microcomputer 74, transmitted from the Bluetooth wireless communication unit (not shown) to the mobile terminal device 3 and stored in the storage unit 34, and the screen shown in FIG. The height of the sill (mm) is displayed in an oval frame.

(Fourth embodiment)
In the third embodiment described above, after the measurement of the dimensions of the room is completed by collecting the data of each measurement point by the method described in the first and second embodiments, The height data is collected by measuring the height of the sill, but in the fourth embodiment, the dimension data of each measurement point (the length to the measurement points around the room based on the center of the room). Each time the polar coordinate data consisting of height data and angle data is collected, threshold height data is collected and input.

  When collecting threshold height data, first, a height input screen shown in FIG. 13 is displayed. The oval frame on this screen displays threshold height data and is initially blank, but at each measurement point, the height of the corresponding measurement point threshold is collected each time room dimension data is collected. Is measured using the measuring device 7, the height data of the threshold is collected, and displayed in the oval frame of the corresponding measurement point. At this time, the room dimension data collected in polar coordinates is not displayed in the rectangular frame because it cannot be converted into XY coordinate system data because the data amount is still small.

  When the collection of the room dimension data and the sill height data for all the measurement points is completed, the sill height (mm) is displayed in an oval frame. It should be noted that every time the data collected in polar coordinates is converted into the XY coordinate system data at all measurement points, data indicating the habit of tatami is displayed in a rectangular frame.

(Fifth embodiment)
In the third and fourth embodiments described above, the dedicated height measuring device 7 is used to measure the height of the threshold, but in the fifth embodiment, a dedicated device is used. Measure the height of the threshold at each measurement point using a commonly used vernier caliper and ruler, and write it down, and enter the written height data separately. It is configured.

  When the measurement of the room dimensions is completed by the method described in the first and second embodiments, the habit is displayed in a rectangular frame as shown in FIG. 14, and the height of the threshold is set for each measurement point. An oval frame to enter is displayed.

  This oval frame is initially blank, but the sill height data is entered using the numeric keypad in the same order as the room dimensions were measured. When the height data of the first measurement point is input with the numeric keypad and the “SET key” is touched, the process proceeds to input of height data of the second measurement point.

  When the same input operation is performed for each measurement point and input of all the height data is completed, when the “registration key” is touched, the height data of the sill together with the dimension data of the room is stored in the storage unit of the mobile terminal device 3 Stored in 34.

(Sixth embodiment)
In the fifth embodiment described above, after collecting the data of each measurement point and measuring the dimensions of the room by the method described in the first and second embodiments, the measurement of each measurement point is completed. Although the height data is collected by measuring the height of the threshold, in the sixth embodiment, the height data of the threshold is collected and input every time the dimension data of each measurement point is collected. Is.

  When collecting the threshold height data, first, the height input screen shown in FIG. 14 is displayed. The oval frame on this screen displays height data and is initially blank, but at each measurement point, each time room size data is collected, the height of the corresponding measurement point threshold is vernier. Collect the height data of the sill by measuring with a ruler and input it with the numeric keypad and display it in the oval frame of the corresponding measurement point.

  At this time, since the data of the room dimensions collected in polar coordinates cannot be converted into XY coordinate system data because the data amount is still small, nothing is displayed in the rectangular frame. Every time the data collected in polar coordinates at all measurement points is converted into XY coordinate system data, data indicating the habit of tatami is displayed in a rectangular frame.
