Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same reference numerals are given to the same objects in a plurality of drawings, and the description is not repeated.

[First Embodiment]
FIG. 1 is a block diagram showing a functional configuration example of the equipment layout drawing creation system according to the first embodiment of the present invention. The equipment layout drawing system 100 shown in FIG. 1 includes a signal generator 90 and an equipment layout drawing device 101. The equipment layout drawing system 100 is a system for creating an indoor equipment layout drawing. Hereinafter, the operation of the equipment layout drawing system 100 will be described in detail with reference to FIG. 1 and other drawings.

The signal generator 90 superimposes a high frequency signal on the metal cable 3 wired indoors. The high frequency signal may be any frequency of a plurality of frequency bands such as the IMS band. The metal cable is a LAN cable, a telephone line, or the like.

As shown in FIG. 1, for example, the metal cable 3 is sandwiched between the clamp probes 91. The clamp probe 91 superimposes a high frequency signal on the metal cable 3 via a magnetic field.

If the clamp probe 91 is used, a high frequency signal can be superimposed on the metal cable 3 without cutting the indoor wiring. Further, even if a plurality of metal cables 3 are bundled, a high frequency signal can be superimposed on each metal cable 3.

FIG. 2 is a diagram schematically showing how the signal generator 90 superimposes a high frequency signal on the metal cable 3. The switch 4 shown in FIG. 2 is a floor switching HUB arranged indoors on each floor of a building, for example, for branching a trunk LAN into a plurality of branch LAN cables.

Signal generator is omitted the notation in Figure 2 90 superimposes a high frequency signal across the branch LAN cable ₃₅ by clamping the probe 91. RF signals may be superimposed on all the branch LAN cable ₃ 1 to 3 _5. It is also possible to change the frequency of the high-frequency signal to be superimposed on each branch LAN cable ₃ 1 to 3 _5.

The high frequency signal may be a sine wave, a triangular wave, or a square wave. Further, a high frequency current may be directly applied to the metal cable 3 to superimpose the high frequency signal. The signal generator 90 is a general one.

The equipment layout drawing creation device 101 includes a camera 20, an image processing unit 30, a moving distance calculation unit 40, a plan view generation unit 50, an electric field strength measurement unit 60, an electric field strength corresponding unit 70, and an equipment layout drawing generation unit 80. .. These functional components are housed inside the moving body 10 to form the equipment layout drawing creating device 101.

The moving body 10 includes a hand-pushing handle 11. The operator operates the push handle 11 to move the moving body 10 on the floor 1 indoors. Further, in the moving body 10, for example, the antenna 61 and the camera 20 are projected to the outside. The antenna 61 is for measuring an electric field.

The metal cable 3 is wired in the wiring space 2 under the floor 1. The metal cable 3 may be wired on the floor 1.

The camera 20 images the traveling direction of the moving body 10 moving on the floor 1 indoors. The camera 20 is, for example, a general digital camera. The image information captured by the camera 20 is output to the image processing unit 30. The image information is preferably moving.

The image processing unit 30 extracts object information existing in the front and left-right directions of the moving body 10 from the image information captured by the camera 20. Assuming that the frame rate of the image information is 24 f / sec to 60 f / sec, the image processing unit 30 extracts, for example, one image from 1 second (24 to 60 frames) and recognizes an object from the image. .. The image extraction interval may be arbitrary, for example, it may be extracted every 1 second or every 0.5 seconds. The camera 20 may capture a still image as long as it cooperates with the movement of the moving body 10.

FIG. 3 is a diagram schematically showing one extracted image. In FIG. 3, the front (traveling direction) of the moving body 10 is defined as y, the left-right direction is defined as x, and the height direction is defined as z. From the image, it can be seen that there is a table 6 on which the personal computer 5 is placed in the −x direction and a shelf 7 in the x direction of the aisle 8.

The image processing unit 30 recognizes the object reflected in the image by extracting the feature amount from the captured image and comparing it with the feature amount associated with the object in advance. The object is, for example, equipment arranged indoors such as a table 6, a shelf 7, a partition, an aisle 8, a chair, a personal computer 5, and a desk. The image processing unit 30 has a feature amount of these equipments in advance.

The moving distance calculation unit 40 calculates the moving distance of the moving body 10 based on a predetermined position indoors. The moving distance can be calculated from the number of rotations of the wheels (reference part number omitted) of the moving body 10. Further, the moving direction can be detected by the direction of the wheels. The moving distance calculation unit 40 is a functional configuration unit that does not need to be provided when the camera 20 is configured by, for example, a 3D camera.

The pixel information of the image captured by the 3D camera includes the distance information to the object. Therefore, in the case of a 3D camera, the position of the camera 20 can be known naturally. Therefore, if the position of the camera 20 is recorded, the moving distance of the moving body 10 can be obtained.

The floor plan generation unit 50 generates indoor floor plan information from the coordinates of the moving body 10 on the floor 1 and the object information extracted by the image processing unit 30. The object information is information representing an object existing in the front and left-right directions of the moving body 10. Therefore, indoor plan view information can be generated from the coordinates of the moving body 10 and the object information.

FIG. 4 is a diagram showing an example of the floor plan information generated by the floor plan generation unit 50. The plan view information shown in FIG. 4 can be generated from the coordinates (x, y) of the moving body 10 and the object information.

For example, it is assumed that the camera 20 has taken an image in the y direction from the position of α. From the image information, the coordinates of the moving body 10, the coordinates of the boundary between the passage 8 and the table 6, and the coordinates of the boundary between the passage 8 and the shelf 7 can be extracted. Plan view information can be generated by connecting these coordinates (x, y). In FIG. 4, β indicates the position of the personal computer 5, and γ indicates the position of the switch 4.

The electric field strength measuring unit 60 measures the electric field strength at the position of the moving body 10. The electric field strength corresponds to the frequency of the high frequency signal superimposed on the metal cable 3 by the signal generator 90. The electric field strength measuring unit 60 may obtain a frequency spectrum by frequency-analyzing the electric field strength in a predetermined frequency band.

The electric field strength corresponding unit 70 associates the electric field strength measured by the electric field strength measuring unit 60 with the coordinates of the moving body 10 of the plan view generating unit 50. The associated coordinates and the value of the electric field strength may be recorded in a memory (not shown).

FIG. 5 is a diagram in which the value of the electric field strength on the coordinates is represented by grayscale contour lines. In this example, the electric field strength of the "white" part is the highest, and the darker the electric field strength, the lower the electric field strength.
The parts of the table 6 and the shelf 7 where the moving body 10 cannot move are indicated by "black", which has the lowest electric field strength because the electric field strength data cannot be obtained. Further, the number of contour lines is approximately proportional to the number of times the moving body 10 is moved by changing the position when the number of antennas 61 is one.

A plurality of antennas 61 may be provided in a direction (x) orthogonal to the traveling direction of the moving body 10. For example, antennas 61 are provided at three locations, the center of the width (x direction) of the moving body 10, the end in the −x direction, and the end in the x direction, and each antenna 61 is switched by a high frequency switch (not shown) to obtain an electric field. It is connected to the strength measuring unit 60. By doing so, it is possible to measure the electric field strengths of three coordinates at a time in the moving body 10 at a predetermined position.

The equipment layout drawing generation unit 80 generates equipment layout drawing information in which the electric field strength is superimposed on the floor plan information generated by the floor plan generation unit 50 by associating them with coordinates. The electric field strength of high-frequency signals near the location of network equipment such as personal computers shows a high value. Therefore, if the electric field strength is superimposed on the plan view information, the equipment arrangement will be shown.

FIG. 6 is a diagram in which the electric field strength is superimposed on the plan view (FIG. 4) in association with the coordinates. As shown in FIG. 6, the electric field strengths are displayed at two locations, one where the personal computer 5 and the like are located (β in FIG. 4) and the other where the switch 4 where the high frequency signal is superimposed on the cable 3 (γ in FIG. 4). .. In addition, the electric field strength around the LAN cable (cable 3) that connects the switch 4 and the personal computer 5 is also displayed high. In this way, it is possible to generate equipment layout information indicating the equipment and wiring configuration. The equipment layout map can be created by outputting the equipment layout map information to, for example, a display device (not shown) or a printing device (not shown).

As described above, the equipment layout drawing system 100 according to the present embodiment is a facility layout drawing system including a signal generator 90 and a facility layout drawing device 101, and the signal generator 90 is wired indoors. The equipment layout drawing device 101 superimposes a high-frequency signal on the metal cable to capture the traveling direction of the moving body 10 moving on the indoor floor 1, and the front of the moving body 10 from the captured image information. Positions of the image processing unit 30 that extracts object information existing in the left-right direction, the plan view generation unit 50 that generates indoor plan view information from the coordinates of the moving body 10 on the floor 1 and the object information, and the position of the moving body 10. The electric field strength measuring unit 60 for measuring the electric field strength, the electric field strength corresponding unit 70 for associating the electric field strength with the coordinates of the moving body 10, and the equipment arrangement in which the electric field strengths are superimposed on the above plan view information by the coordinates. It is provided with a facility layout diagram generation unit 80 that generates diagram information. As a result, it is possible to create an indoor equipment layout drawing by a simple operation in which one worker simply moves the moving body 10 indoors. Moreover, since the position of the equipment is specified based on the electric field distribution in the room, it is possible to create an accurate equipment layout without oversight.

The electric field strength measuring unit 60 may be provided with a plurality of antennas 61 at intervals in a direction orthogonal to the traveling direction of the moving body 10, and may be configured to measure the electric field strength of each antenna 61. By doing so, a plurality of electric field strengths can be measured at one time, and the number of times the moving body 10 is repeatedly moved can be reduced.

[Second Embodiment]
FIG. 7 is a block diagram showing a functional configuration example of the equipment layout drawing creation system according to the second embodiment of the present invention. The equipment layout drawing creation device 102 shown in FIG. 7 is different from the equipment layout drawing creation device 101 (FIG. 1) in that it includes a passage information extraction unit 230 and a locus generation unit 250.

The passage information extraction unit 230 extracts the passage information on which the moving body 10 can move from the image information captured by the camera 20. The passage information extraction unit 230 recognizes only the passage 8 included in the image information and extracts the coordinate information (passage information) thereof.

The locus generation unit 250 generates locus information on which the moving body 10 has moved from the coordinates of the moving body 10 and the passage information extracted by the passage information extracting unit 230. FIG. 8 shows the locus information generated by the locus generation unit 250. As shown in FIG. 8, the shape of the passage and the locus of the moving body 10 are included.

FIG. 9 is a diagram showing an example of an equipment layout diagram in which the electric field strength is superimposed on the locus information generated by the locus generation unit 250 in association with coordinates. As shown in FIG. 9, the electric field strength around the personal computer 5 and the like is displayed high. Therefore, the equipment layout drawing system 200 of the present embodiment can also create the equipment layout drawing (FIG. 6).

In the equipment layout drawing system 200, attention may be paid only to the moving locus of the moving body 10. In that case, the camera 20 and the passage information extraction unit 230 are unnecessary.

The equipment layout map information may be generated by associating the information of only the locus of the moving body 10 generated by the locus generation unit 250 with the coordinates and superimposing the electric field strength.

As described above, the equipment layout diagram creation system 200 according to the present embodiment is an equipment layout diagram creation system including a signal generator 90 and an equipment layout diagram creation device 102, and the signal generator 90 is wired indoors. A locus generator 250 that superimposes a high-frequency signal on the metal cable and generates locus information on the movement of the moving body 10 from a change in the coordinates of the moving body 10 moving on the floor 1 indoors, and the positions of the moving body 10. The electric field strength measuring unit 60 for measuring the electric field strength, the electric field strength corresponding unit 70 for associating the electric field strength with the coordinates of the moving body 10, and the equipment layout diagram information in which the electric field strength is superimposed on the locus information by the coordinates. It is provided with an equipment layout diagram generation unit 80 to be generated. This makes it possible to create an indoor equipment layout plan.

As shown in FIG. 7, the equipment layout drawing system 200 may include a camera 20 and a passage information extraction unit 230. By providing these functional components, it is possible to create an equipment layout drawing including information on the passage 8.

[Third Embodiment]
FIG. 10 is a block diagram showing a functional configuration example of the equipment layout drawing creation system according to the third embodiment of the present invention. In the equipment layout diagram creation system 300 shown in FIG. 10, the signal generator 390 includes a signal generation cooperation unit 391, and the equipment layout diagram creation device 103 includes a signal generation cooperation unit 311. Different from 1).

The signal generation cooperation unit 311 included in the equipment layout drawing device 391 and the signal generation cooperation unit 392 included in the signal generator 390 are connected by short-range wireless communication such as Bluetooth and wireless LAN (Wi-Fi).

While pressing the equipment layout drawing device 103 (moving body 10), the operator operates an operation switch (not shown) to act on the signal linkage unit 391 of the signal generator 390 to turn on / off a high frequency signal having a predetermined frequency. Or change the frequency. By doing so, the measurement accuracy of the electric field strength can be improved.

For example, it is possible to easily determine the presence or absence of a predetermined facility by comparing the electric field strength when a predetermined high frequency signal is superimposed and the electric field strength when a predetermined high frequency signal is not superimposed.

The signal generation cooperation unit 311 and the signal generation cooperation unit 391 may selectively turn on / off high frequency signals of a plurality of frequencies, or may change each of the plurality of frequencies. By doing so, it is possible to increase the types of electric field strength measurement targets.

(How to create equipment layout)
FIG. 11 is a flowchart showing a processing procedure of the equipment layout drawing creation method performed by the equipment layout drawing creation system 100 (FIG. 1).

When the equipment layout drawing system 100 is used to create an indoor equipment layout drawing, the signal generator 90 is first operated, and the signal generation application step S1 for superimposing a high frequency signal on the predetermined metal cable 3 is executed.

Next, after moving the moving body 10 to a predetermined position indoors, the operator resets if the past data remains in the working area of the memory (reset is omitted in FIG. 11).

After the reset, the camera 20 executes an imaging step S2 for capturing the traveling direction of the moving body 10 moving on the floor 1 indoors. The image captured by the camera 20 may be either a still image or a moving image.

The image processing unit 30 executes an image processing step S3 that extracts object information existing in the front and left-right directions of the moving body 10 from the image information captured by the camera 20. Object information is identified based on features. Features are prepared in advance by machine learning. Machine learning uses, for example, a well-known support vector machine.

The moving distance calculation unit 40 executes the moving distance calculation step S4 for calculating the distance based on the number of rotations of the wheels of the moving body 10. The direction of movement is detected by the change in the direction of the wheels. Here, since the moving body 10 has not moved, the position of the moving body 10 whose memory has been reset becomes the reference point (x = 0, y = 0).

The floor plan generation unit 50 executes the floor plan generation step S5 for generating indoor floor plan information from the coordinates of the moving body 10 and the object information. The plan view generation unit 50 records the coordinates of the reference point (x = 0, y = 0) and the object information existing on the left and right sides of the coordinates. For example, if there is a table 6 on the −x side of the passage 8 and a shelf 7 on the x side, the coordinates of the boundary between each object and the passage 8 are recorded in the memory.

The electric field strength measuring unit 60 executes the electric field strength measuring step S6 for measuring the electric field strength at the position (x = 0, y = 0) of the moving body 10.

The electric field strength corresponding unit 70 executes the electric field strength associating step S7 for recording the electric field strength measured by the electric field strength measuring unit 60 and the position (x = 0, y = 0) of the moving body 10 in the memory. ..

If the moving body 10 has not moved from the reference point (x = 0, y = 0), the loop of No in step S8 and NO in step S9 is repeated. When the moving body 10 moves from the reference point (x = 0, y = 0), the processing of the imaging step S2 to the electric field strength mapping step S7 is repeated.

The processing speed for executing the processing of the imaging step S2 to the electric field strength associating step S7 is sufficiently faster than the speed at which the wheels rotate once and the moving distance is updated when the moving body 10 is moved at the speed at which a person walks. To do. By doing so, the equipment layout map information can be generated even if the moving body 10 is moved at that speed.

When the operator presses the equipment layout drawing generation switch (not shown) after finishing the movement of the moving body 10, the equipment layout drawing generation unit 80 coordinates on the floor plan information generated by the floor plan generation unit 50. Generate equipment layout map information in which the electric field strengths are superimposed in association with each other.

(Modification example 1)
Each functional component of the equipment layout drawing device 101 may be mounted on a radio-controlled unmanned aerial vehicle (drone) instead of being mounted on the moving body 10 moving on the floor 1.

FIG. 12 is a block diagram showing a functional configuration example of the equipment layout drawing creation system 400 of the modification 1 in which each functional configuration unit of the equipment layout drawing creation device 101 is mounted on a radio-controlled unmanned machine 410.

The unmanned aerial vehicle 410 differs from the moving body 10 in that it includes a flight control unit 411, a movement distance calculation unit 440, and a flight control unit 411. Since the unmanned aerial vehicle 410 does not have wheels, the moving distance calculation unit 440 calculates the moving distance from the acceleration detected by the three-axis acceleration sensor (not shown). The sensitivity of the z-axis accelerometer that is not used to generate the plan view information may be kept low or ignored.

The flight control unit 411 controls the lift generated by the rotation of the four propellers 412a to 412d based on the command from the recommon operated by the operator to fly the unmanned aerial vehicle 410. Other functional components are the same as the equipment layout drawing creation system 100, as is clear from the reference reference numerals. In this way, the equipment layout drawing creating device 101 may be configured to fly. By doing so, it is possible to generate equipment layout map information even when there is an obstacle on the floor 1.

The unmanned aerial vehicle 410 does not have to obtain lift with a propeller. For example, it may be a type of unmanned aerial vehicle (drone) that obtains lift by using a gas having a light specific gravity such as a balloon or a balloon. Moreover, it is not necessary to have the propulsive force by the propeller. The worker may walk by pulling a floating drone tied with a thread.

(Modification 2)
The equipment layout drawing system 500 may be configured by combining a flying unmanned aerial vehicle and a moving body that moves on the floor 1.

FIG. 13 is a block diagram showing a functional configuration example of the unmanned aerial vehicle of the modified example 2 in which the equipment layout drawing creation system 500 is configured by the combination of the unmanned aerial vehicle 510 and the mobile body 511. As shown in FIG. 13, the unmanned aerial vehicle 510 of the second modification is different from the unmanned aerial vehicle 410 in that it does not include the electric field strength measuring unit 60, the electric field strength corresponding unit 70, and the equipment layout drawing generating unit 80. The unmanned aerial vehicle 510 independently generates the plan view information.

FIG. 14 is a block diagram showing a functional configuration example of the moving body 511. The moving body 511 shown in FIG. 14 does not include the camera 20 and the image processing unit 30.

Even if the camera 20 and the image processing unit 30 are not provided, the movement locus information of the moving body 511 can be recorded by recording the change in the coordinates due to the moving distance calculated from the rotation speed of the wheel. The distribution of the electric field strength can be recorded by superimposing the electric field strength on the coordinates.

Equipment layout information can be generated by superimposing the distribution of the electric field strength recorded by the moving body 511 on the plan view information generated by the unmanned aerial vehicle 510. As described above, the equipment layout drawing system 500 can also be configured by a combination of the unmanned aerial vehicle 510 and the mobile body 511.

As described above, according to the equipment layout drawing creation systems 100, 200, and 300 according to the present embodiment, indoor equipment layout drawing information can be generated by a simple operation of moving the equipment layout drawing creation device. Moreover, since the position of the equipment is specified based on the electric field distribution in the room, it is possible to create an accurate equipment layout without oversight.

In the third embodiment, a configuration in which the signal generation cooperation units 311, 392 are added to the configuration of the equipment layout drawing creation system 200 can be considered. The same operation and effect as the configuration in which the signal generation cooperation units 311, 392 are added to the configuration of the equipment layout drawing system 100 (FIG. 1) can be obtained.

Further, although an example in which the camera 20 and the antenna 61 are projected to the outside of the moving body 10 is shown, the present invention is not limited to this example. The camera 20 and the antenna 61 may be housed inside the moving body 10.

The equipment layout drawing devices 101, 102, and 103 can be realized by a computer including, for example, a ROM, a RAM, a CPU, or the like, except for the camera 20 and the electric field strength measuring unit 60. When each functional configuration unit is realized by a computer, the processing content of the function that each functional configuration unit should have is described by a program.

When the equipment layout drawing creating devices 101, 102, and 103 are configured by a computer, the equipment layout drawing creating systems 100, 200, and 300 can be configured by mounting the computer on a general trolley.

As described above, the present invention includes various embodiments not described here. Therefore, the technical scope of the present invention is defined only by the matters specifying the invention relating to the reasonable claims from the above description.
