JP 2004-4297 A JP 2007-280282 A

However, in Patent Document 1, a target position that is an inspection position is displayed together with map information, and an operator position and a target position are displayed so as to be distinguishable using symbols, marks, and the like. In Patent Document 2, a point requiring inspection is a bridge. Although it is indicated by a circle or the like in the drawing, there is a possibility that the inspection position may be overlooked.
For example, when inspecting a tunnel or bridge, even if the inspection position is overlooked, it should be noted before the end of the work, but if it passes, it must be reversed, which is inefficient.

  Therefore, an object of the present invention is to provide a work support device and a work support program that can perform efficient work by preventing inspection omissions.

  The work support device according to the present invention includes a storage means for storing inspection coordinate data including the inspection longitude data indicating the longitude of the inspection point and the latitude indicating the latitude in the inspection target facility, the longitude at which the operator is located, and If the position data from the positioning means for positioning the latitude is within a predetermined range centered on the position indicated by the inspection coordinate data, a detection notification indicating that the operator is within the predetermined range of the inspection location is issued. It is characterized by comprising: a determination means for outputting; and a position notification means for notifying the operator of the inspection location by sound generated by the sound generation means in response to the detection notification being output from the determination means.

  In addition, the work support program of the present invention includes a computer, longitude data indicating the longitude of an inspection point in the inspection target facility, in which position data from a positioning unit that measures the longitude and latitude at which the worker is located is read from the storage unit; A determination unit that outputs a detection notification indicating that the worker is at the inspection location if the operator is located within a predetermined range centered on the position indicated by the inspection coordinate data including latitude data indicating the latitude, the determination unit In response to the output of the detection notification from the sound generator, it is made to function as a position notification means for notifying the operator of the inspection location by sound generated by the sound generation means.

  In the present invention, based on the inspection coordinate data stored in the storage means, the determination means determines whether or not the operator has approached the inspection location, and the position is within a predetermined range centered on the position indicated by the inspection coordinate data. If so, the determination means outputs a detection notification indicating that the worker is within the predetermined range of the inspection location, and the position notification means informs the operator of the inspection location by sound from the sound generation means. is there. With this configuration, the operator can know that he / she has approached the inspection location by sound, so that the inspection location can be prevented from being overlooked.

  The position data from the positioning means includes height data indicating the height at which the operator is located, and the inspection coordinate data stored in the storage means includes inspection height data indicating the height of the inspection location. The determination means includes a first range in which the position data indicating the position of the operator is a predetermined range in the horizontal direction centered on the position indicated by the inspection longitude data and the inspection latitude data. And a second range that is a predetermined range in the vertical direction centered on the inspection height data, and the position notification means includes the position data within the first range and the second range. It is desirable to notify with a different sound depending on whether it is out of the second range or in the second range.

  When the predetermined range determined by the determination unit is, for example, several meters, when it is determined whether or not the operator has approached in the range of several meters uniformly in the horizontal and vertical directions, the height is 5 m or 10 m or more. At a certain inspection position, an operator who moves on the ground at an altitude of 0 m is not included in the predetermined range and may pass by mistake. First, the operator enters the first range, which is a predetermined range in the horizontal direction, and notifies the operator that the inspection location is close regardless of the height, so that the operator is unaware. It can be prevented from passing. Furthermore, since it approaches in the height direction and falls within the second range, it is notified with a different sound, and as a result of moving to a higher position or a lower position, it can be known that the inspection location has been approached.

Inspection image registration means for storing inspection image data obtained by imaging an inspection location in the storage means in association with inspection coordinate data indicating the location of the inspection location; and when the operator is positioned within a predetermined range of the inspection location The inspection image reading means for reading the inspection image data associated with the inspection coordinate data indicating the position of the inspection location and displaying the inspection image data on the display means may be provided.
Since the image reading means reads the image data associated with the inspection coordinate data indicating the position of the inspection location and displays it on the display means, it is possible not only to grasp the specific inspection position from the inspection image data but also to repair, for example, It is possible to check the status immediately after the comparison and compare it with the current status, or to check the status of the previous inspection location.

The storage means stores the inspection coordinate data indicating the position of the inspection location in association with the order data indicating the inspection order, the inspection coordinate data serving as the starting point indicating the inspection location being checked by the operator, and the order data It is also possible to provide a distance calculation means for calculating the movement distance from the inspection coordinate data that is the target point indicating the next inspection location searched based on the above and displaying it on the display means.
Since the distance from the inspection location being inspected to the next inspection location is calculated by the distance calculation means, the operator can quickly know the time until the next operation can be started.

Completion processing means for associating an inspection completion flag indicating that inspection has been completed with inspection coordinate data of an inspection location that has been inspected and registering it in the storage means in accordance with an inspection completion notification indicating inspection completion input by the input means, The means does not output a detection notification if the inspection completion flag is associated with the inspection coordinate data even if the position data indicating the position of the operator is located within a predetermined range centering on the inspection coordinate data. It is also possible.
When the inspection is completed, the operator inputs the completion of inspection through the input means. With this input, the completion processing means associates an inspection completion flag indicating that inspection has been completed with the inspection coordinate data of the inspection location and registers it in the storage means. By doing so, even if the position data indicating the position of the operator is located within a predetermined range centered on the inspection coordinate data, the determination means is associated with the inspection completion flag in the inspection coordinate data, Since the detection notification is not output, it is possible to prevent the same inspection point from being inadvertently inspected.

  According to the present invention, since the operator can know that the inspection location is approached by sound, it is possible to prevent the inspection location from being overlooked, so that an efficient inspection operation can be performed.

The order data indicates the inspection order of the inspection locations, and data in ascending order from the start location to the end location is assigned.

  The operation and use state of the work support system 1 according to the embodiment of the present invention configured as described above will be described with reference to the drawings, taking as an example the inspection of the disaster prevention facility of the care facility where the facility to be inspected is installed. To do. First, in order to display a plan view, which is a sketch of a care facility, on the display means 3h of the work support server 3, an operation for associating the measured coordinates with the plan view, which is a paper drawing, as electronic data will be described.

First, as a preparation, the administrator operates the input unit 3j of the work support server 3 to read a plan view of the care facility set in the scanner device 4 as drawing data. The read drawing data is stored in the storage means 3q via the connection means 3m. As a plan view of the care facility, four rooftops are prepared from the first floor to the third floor.
Next, the survey coordinate is registered by the coordinate registration means 3n. The administrator displays the drawing data and inputs a reference coordinate. Then, for example, survey coordinate data is obtained by measuring the longitude and latitude of the position of the building corresponding to the points P11 to P13 which are survey points in the floor plan G1 shown in FIG. 4A and the height of the floor plan G1. (Surveying longitude data, surveying latitude data, surveying height data), and this surveying coordinate data is stored in the storage means 3q in association with the drawing coordinate data which is the coordinates on the drawing where the points P11 to P13 of the drawing G1 are located. This association can be made by inputting the survey coordinate data at positions corresponding to the points P11 to P13 of the sketch drawing G1 in another layer after the image data to be the sketch drawing G1 is read in a predetermined layer by CAD software. That is, by superimposing these two layers, the facility data associated with them can be obtained. Similarly, even when the drawing data to be the sketch drawing G1 is CAD data, the CAD data is read in a predetermined layer and superimposed with another layer to which surveying coordinate data is input, so that the drawing data associated with these can be can do.
The coordinates of these survey points are surveyed by the surveyor in advance and input by the administrator based on the survey point coordinate list shown in FIG.

  Points P11 and P12 are left and right direction detection points, and point P13 is a vertical direction detection point. In addition, about the point of measurement, the case of the first floor shown in FIG. 4 (A) also in the floor plans G2 to G4 of the second floor and the third floor shown in FIG. 4 (B) to FIG. Similarly, points P21 to P43 are set.

  The points P11 and P12 are located on an imaginary line parallel to the horizontal direction of the sketch drawing G1. In the floor plan G1 on the first floor shown in FIG. 4 (A), the outer wall surface on the entrance / exit side of the office can be regarded as a virtual line parallel to the horizontal direction of the floor plan G1, so both ends of the outer wall surface on the entrance / exit side of the office Are designated as points P11 and P12. Similarly, in the floor plan G2 on the second floor shown in FIG. 4B, the outer wall surface from the entertainment room to the rehabilitation room can be regarded as an imaginary line parallel to the horizontal direction of the floor plan G2, so that both ends of the outer wall surface are points. Designated as P21 and P22. In this way, the survey coordinate is registered by the coordinate registration means 3n.

  Next, registration of inspection information by the coordinate registration means 3n will be described. In registering the inspection information, first, the drawing display processing means 3p reads out the drawing data and displays it on the display means 3h.

  For example, it is assumed that the sketch G1 is displayed as it is on the display screen of the display means 3h based on the survey longitude data and survey latitude data of the points P11 and P12. In this case, orthogonal coordinate axes (surveying coordinates) where the vertical direction of the display screen is the meridian direction along the meridian (latitude direction where the latitude increases or decreases) and the horizontal direction is the parallel direction along the latitude line (the longitude direction where the longitude increases or decreases) Since the screen is north-up (north is facing upward) with reference to the coordinate axis of the system, the floor plan G1 is displayed according to the actual building situation, so the building is constructed with the building tilted to the north. If it is done, the sketch G1 is displayed in an inclined state. In this case, not only the building display and the character display are inclined, but also the degree of reduction of the entire rectangular sketch G1 needs to be increased, which is more difficult to see.

Therefore, when the drawing display processing means 3p reads and displays it, the inclination of the drawing data showing the sketch G1 is calculated, and the inclination of the drawing data is calculated.
This inclination is a virtual straight line L1 (same as the wall surface W1 in FIG. 6) connecting the points P11 and P12 of the sketch G1 indicated by the survey coordinate data (surveying longitude data and survey latitude data), and the survey coordinates passing through the point P11. It can be calculated by calculating the angle formed by the longitude direction of the system (indicated by a dashed-dotted virtual line L2 in FIG. 6) as the correction angle θ.

This calculation can be calculated by the following equation (1) because the virtual straight line L2 connecting the points P11 and P12 on the sketch G1 is a virtual line parallel to the horizontal direction of the sketch G1.
Correction angle θ = tan ⁻¹ [(Y′−Y) / (X′−X)] (1)
However, the longitude of the point P11 is X, the latitude is Y, the longitude of the point P12 is X ', and the latitude is Y'.

Then, the drawing display processing means 3p rotates the drawing data indicating the sketch G1 based on the drawing coordinate data of the points P11 and P12 based on the correction angle θ, thereby correcting the corrected sketch G1 shown in FIG. Generate drawing data. At this time, when the correction angle θ is a positive value, it is rotated clockwise, and when it is negative, it is rotated counterclockwise.
By doing so, it is possible to obtain a display in which the horizontal direction and vertical direction of the sketch coincide with the horizontal direction and vertical direction of the display screen.

  When the corrected drawing data is generated, not only the drawing data is rotated, but also the display size is enlarged or reduced in accordance with the screen size (resolution) of the display means 3h, so that it is possible to obtain a more easily viewable drawing. Hereinafter, the corrected drawing data is simply referred to as drawing data.

To register the inspection location, the input means 3j is operated on the drawing data displayed on the display means 3h, the inspection longitude data indicating the longitude of the inspection location, the inspection latitude data indicating the latitude, and the height of the inspection location. Enter and associate the inspection height data shown. This association can be performed in the same manner as the association of survey coordinates.
In this Embodiment, the fitting as a fire prevention equipment installed in the pit hole division and the different use division of a nursing care facility is targeted. An inspection location MP1 shown in FIG. 8D is a fire door that divides the rooftop staircase S and the machine room M from each other. An inspection location MP2 shown in FIG. 8C is a fire door that is always open and divides the stairs S and the corridor R1 on the third floor. The inspection location MP3 shown in FIG. 8 (B) is a fire door that is always open and divides the stairs S and the corridor R2 on the second floor. An inspection location MP4 shown in FIG. 8A is a fire door that is always open between the staircase S and the hall H on the first floor. An inspection location MP5 shown in FIG. 8A is a fire door that partitions the kitchen KC and the parking lot PK.

  The inspection coordinate data for these inspection locations MP1 to MP5 is surveyed in advance, and the survey location is set near the center of the inspection locations MP1 to MP5. For example, when the inspection locations MP2 to MP4 are double doors, the survey location is the position where the left and right doors meet. Moreover, when the inspection locations MP1 and MP5 are single doors, the position of the hinge is set as the survey location.

The administrator reads sketches G1 to G4 for these inspection points MP1 to MP5, inputs inspection longitude data, inspection latitude data, and inspection height data, and sets the inspection order to the inspection points MP1 to MP5. Enter each. In this Embodiment, it is set as the order of inspection location MP1-MP5 checked while going down the stairs from the roof to the first floor. When these are input, the coordinate registration unit 3n gives an arrow indicating the inspection location to the drawing data and stores the information in the storage unit 3q as inspection information.
The coordinates of these inspection locations are surveyed by the surveyor in advance, and are input by the administrator based on what is compiled in the coordinate list of the inspection locations shown in FIG. At that time, the inspection order is also entered.

  In this way, when the registration of the inspection information is completed, the work support server 3 can be used for the inspection work. In the work support server 3, it is assumed that the determination unit 3b is set in advance for a range for determining whether or not the worker has approached the inspection location.

  In the inspection work, the operator operates the portable terminal device 2 and requests the work support server 3 for a sketch drawing describing the first inspection location. In the work support server 3, the drawing display processing means 3p reads the drawing data including the first inspection location in the order data from the storage means 3q together with the associated drawing coordinate data and inspection coordinate data, and the communication means 3a. To the mobile terminal device 2 via

  In the mobile terminal device 2, the drawing display processing unit 2 g generates corrected drawing data obtained by correcting the received drawing data based on survey coordinates associated with the drawing data, and displays the corrected drawing data on the display unit 2 h. By doing so, on the mobile terminal device 2 side as well, the horizontal direction and vertical direction of the sketch can be made to coincide with the horizontal direction and vertical direction of the display screen.

  While referring to the drawing data displayed on the display means 2h, the operator approaches the first inspection location MP1 while going up the stairs S. In the mobile terminal device 2, the position data measured by the positioning unit 2c is transmitted to the work support server 3 via the wireless unit 2a. In the work support server 3, the determination unit 3 b sequentially receives the position data from the mobile terminal device 2 and determines whether or not it is within a predetermined range of the inspection location indicated by the inspection longitude data and the inspection latitude data. Moreover, the determination means 3b determines whether the position data from the portable terminal device 2 is within a predetermined range of the inspection height data. In this case, the determination means 3b determines the first inspection location MP1 where the inspection is not completed because the inspection completion flag is not set.

  That is, as shown in FIG. 10, the determination means 3b operates within a circle having a predetermined radius r centered on the coordinates indicated by the inspection longitude data and the inspection latitude data of the inspection location MP1, regardless of the height direction. It is determined as the first range S1 whether or not the positioning longitude data indicating the position of the person and the positioning latitude data are included. For example, if the predetermined range in the horizontal direction is set as a radius of 5 m, the operator is located within a cylindrical shape having a radius of 5 m with the inspection point MP1 as the center within the first range S1. Further, the determination means 3b determines whether or not the positioning height data indicating the position of the operator is included in the first range S1 and the predetermined range of the inspection height data of the inspection point MP1. The range is determined as S2. For example, if the predetermined range in the vertical direction is set to 3 m, when the worker goes up the stairs S from the first floor, the operator is within the cylindrical shape with a radius of 5 m centered on the inspection location MP1, and thus falls within the first range S1. However, since the height is 3 m or more away from the inspection location MP1, it is not determined as the second range S2.

  If the determination means 3b determines that it is within the first range S1, a detection notification indicating that it is within the first range S1 is output to the position notification means 3c. The position notification means 3c receives a detection notification indicating that the position is within the first range S1 from the determination means 3b, and transmits a first notification notification for notifying the worker by sound to the mobile terminal device 2.

  The mobile terminal device 2 receives the first notification from the work support server 3 and the sound generation means 2d generates a first sound corresponding to the first notification so that the horizontal direction around the inspection point MP1 is obtained. That the operator is located within a radius of 5 m. The operator can confirm that the first check point MP1 is approaching by the first sound.

  The operator can further approach the inspection location MP1 by knowing that the inspection location MP1 is approached by the first sound. The worker climbs the stairs and gradually approaches the inspection location MP1 to enter the second range S2. The determination unit 3b outputs a detection notification indicating that the worker is in the second range S2 to the position notification unit 3c when the worker is in the second range S2. The position notification unit 3c receives a detection notification indicating that the position is within the second range S2 from the determination unit 3b, and transmits to the portable terminal device 2 a second notification for notification to the worker by sound.

In the portable terminal device 2, the operator receives the second notification from the work support server 3, and the sound generation means 2d generates the second sound corresponding to the second notification, so that the operator can check the height of the inspection point MP1. That it is located within 3m. The operator can confirm that the second inspection sound has further approached the first inspection location MP1.
If the first sound is an intermittent sound, the second sound can be a continuous sound. In addition, the second sound can be higher than the first sound. Furthermore, the first sound and the second sound may be voice messages.

  Further, the determination unit 3b may notify the position notification unit 3c of the third detection notification when the inspection coordinate data of the inspection point MP1 and the positioning coordinate data indicating the worker's position match. . The portable terminal device 2 can notify the operator that the user is at the inspection location MP1 by generating the third sound by the sound generation means 2d by the third detection notification.

When the inspection of the inspection point MP1, which is the first inspection point, is completed, the operator operates the imaging unit 2e to transmit inspection image data obtained by photographing the inspection point MP1 to the work support server 3. In the work support server 3, the inspection image data received by the inspection image registration unit 3e is associated with the inspection identification data by associating with inspection identification data as inspection information, and is stored in the storage unit 3q.
At the next periodic inspection, inspection image data associated with inspection coordinate data indicating the position of the inspection location is read out by the inspection image reading unit 3f, transmitted to the portable terminal device 2, and displayed on the display unit 2h. In addition to being able to grasp the specific inspection position, for example, it is possible to confirm the state immediately after repair and compare it with the current state, or to confirm the state of the previous inspection location.

  Then, the operator operates the input unit 2j to transmit an inspection completion flag indicating that the inspection is completed for the inspection location MP1 to the work support server 3 by the inspection completion notification unit 2f. The work support server 3 receives the inspection completion flag from the portable terminal device 2, and the completion processing means 3d associates the inspection completion flag with the inspection identification data, thereby associating with the inspection coordinate data and storing it in the storage means 3q. To do.

  Upon completion of the inspection of the inspection location MP1, the drawing display processing means 3p sends the drawing data including the inspection location with the second order data from the storage means 3q together with the associated drawing coordinate data and inspection coordinate data. Read and transmit to the mobile terminal device 2 via the communication means 3a. The mobile terminal device 2 displays the received drawing data based on the drawing coordinate data.

  Further, the distance calculation means 3k is based on the order data indicating the inspection order, and the moving distance with the inspection coordinate data indicating the position of the inspection point MP1 as the starting point and the inspection coordinate data indicating the position of the next inspection point MP2 as the target point Is calculated and transmitted to the mobile terminal device 2. In the mobile terminal device 2, the received moving distance is displayed on the display means 2h. By displaying the movement distance, the worker can quickly know the time until the next work can be started.

  Moreover, the determination means 3b determines that the next inspection location MP2 is determined with reference to the order data in response to the completion of the inspection location MP1. The inspection location MP2 is located at substantially the same longitude and latitude as the inspection location MP1, and has a different height. Therefore, the determination unit 3b notifies the position notification unit 3c of the first detection notification by determining that the worker is within the first range S1. As described above, the completion processing means 3d registers the inspection completion flag indicating that inspection has been completed in the storage means, so that the position data indicating the position of the operator is located within a predetermined range centered on the inspection coordinate data. However, since the determination means 3b does not output a detection notification at the same inspection location, it can be prevented that the same inspection location is inadvertently checked, and the next inspection location can be determined.

In the mobile terminal device 2, the first sound is generated by the first notification notified by the position notification unit 3 c of the work support server 3. By changing from the second sound to the first sound, the operator can recognize that the next inspection location MP2 has the same longitude / latitude and a different height.
The worker goes down the stairs S and moves to the third floor, so that the worker enters the second range S2 from the first range S1, so the next inspection is performed by the change from the first sound to the second sound. It can be confirmed that the location MP2 is a normally open fire door that divides the stairs S and the corridor R2 on the third floor.

The operator goes down the stairs S from the inspection location MP1 to the inspection location MP5 in the same manner, and checks while moving from the kitchen KC to the parking lot PK.
As described above, in the work support system according to the present embodiment, the operator can know that the inspection points MP1 to MP5 are approached by sound, thereby preventing the inspection points MP1 to MP5 from being overlooked. Therefore, efficient inspection work can be performed.

  In addition, when the worker enters the first range S1 that is a predetermined range in the horizontal direction, the worker is notified by sound that the inspection points MP1 to MP5 are close to each other regardless of the height. It is possible to prevent the person from passing through without noticing. Furthermore, since it approaches the height direction and falls within the second range S2, it is notified with a different sound, so that it has moved closer to a higher floor or a lower floor, and as a result, knows that it has approached inspection points MP1 to MP5. be able to.

  The work support system according to the embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the present embodiment, the mobile terminal device 2 carried by the worker and the work support server 3 are configured. However, the mobile terminal device 2 includes a determination unit 3b, a position notification unit 3c, and a completion processing unit. 3d, inspection image registration means 3e, inspection image reading means 3f, distance calculation means 3k, coordinate registration means 3n, and storage means 3q are provided together so that the portable terminal device 2 can be used as a work support device. Can function. Therefore, since the maintenance work can be performed only with the mobile terminal device, the inspection work can be performed even in a factory or facility where communication with the relay station R is difficult.

  The present invention is suitable for manufacturing facilities such as factories, industrial complexes, plants, various facilities, inspection of production facilities or disaster prevention facilities, inspection of buildings such as bridges and tunnels, and the like.
