  In the disaster prevention system described in Patent Document 1, the 3D coordinate data of a structure is converted into machine coordinates (coordinates with respect to a standard point and coordinates for specifying an absolute position on the earth) using a 3D laser scanner. Since it has been acquired, when this structure is displayed on the display screen, the display is performed based on the machine coordinates.

  However, when the building image is displayed on the display screen, the structure is based on the acquired machine coordinates with the virtual axis along the vertical direction of the display screen and the horizontal direction orthogonal to the vertical direction as a reference coordinate axis. When an image of an object is displayed, an image of the building is displayed according to the actual building situation, so that a rectangular building in a plan view is displayed diagonally along the diagonal line of the display screen, The place where the front faces downward of the display screen faces upward, and it becomes difficult to see. In such a case, there is a risk that the instruction of the conductor who instructs the rescue operation from outside the building may be inappropriate or the instruction may be delayed, which may hinder the rescue operation. As a result, the position detection device such as the rescue operation support device displays the position of the rescuer who is the monitored person so that the conductor who is the monitored person can intuitively and accurately grasp the position of the rescuer. is important.

And a control unit that superimposes a mark indicating the position of the monitored person on the basis of the position data and outputs the mark to a display screen.

  In the position detection apparatus of the present invention, the control means first measures the virtual straight line connecting the two points based on the survey coordinate data of the two points assigned on the virtual straight line parallel to the vertical or horizontal direction of the sketch. The inclination with respect to the coordinate axis of the coordinate system is calculated as a correction angle. That is, this correction angle is the inclination of the plan view when the vertical direction of the display screen is the meridian direction (latitude direction) and the horizontal direction is the latitude direction (longitude direction). Therefore, the control means displays the corrected plan view data obtained by rotating the plan view data based on the correction angle on the display screen, so that the vertical direction and the horizontal direction of the sketch coincide with the vertical direction and the horizontal direction of the display screen. Can be displayed. The control means superimposes a mark indicating the position of the monitored person on the corrected plan view data based on the position data, so that the monitoring person can accurately and quickly grasp the position of the monitored person. Therefore, the monitor who observes the monitored person from the outside of the facility can accurately recognize the position of the monitored person.

When reading the plan view data from the paper drawing, first, the reading control means 35j is activated, and the sketch drawing as the paper drawing is read by the scanner device 4 and stored in the storage means 34.

  When the paper drawing is read by the scanner device 4 with an automatic paper feeding mechanism, the paper drawing may be skewed as shown in FIG. That is, when the paper drawing is conveyed to the image reading mechanism by the automatic paper feeding mechanism of the scanner device 4, the image image generated as the plan view data is read by being inclined with respect to the traveling method. The display screen is inclined with respect to the vertical direction and the horizontal direction.

  Although some scanners perform skew correction on the scanner device 4 side, when the scanner device 4 does not have the skew correction function, the skew angle detection means 35g has an edge on the front side of the read plan view data. Is detected as the skew angle φ and the angle β between the side of the plan view data and the travel direction is associated with the plan view data as the skew correction data. And stored in the storage means 34.

The skew angle φ can be a positive angle if tilted as shown in FIG. 6, and a negative angle if tilted in the opposite direction.
Although it is possible to store the plan view data after correcting the skew in advance, in the present embodiment, even if the plan view data is skewed, the plan view data and the plan view data are left as they are. Row correction data is stored in association.

For the electronic data generated by reading the floor plan data with CAD and the sketch drawing of the paper drawing with the scanner device, the survey point of the building surveyed in advance on the operation screen shown in FIG. An operation for associating the point on the plan view data corresponding to the survey point is performed. Therefore, before the association work on the operation screen shown in FIG. 7, for example, if the sketch is G1, points P11 to P13 are determined in advance, and the surveying on the site and the point setting (coordinate plot) on the sketch G1 are completed. It is necessary to keep it.
However, if the plan view data of the sketch drawing G1 is obtained by reading a paper drawing with the scanner device 4 and read in a skewed state at that time, the point setting on the sketch drawing G1 is performed by the sketch drawing G1. It is set in a skewed state.

  The operation screen OP shown in FIG. 7 is displayed by the facility data setting means 35h. In the upper part of the operation screen OP, a name input field R1 for inputting a name indicating a building is provided. In the middle of the operation screen OP, a survey coordinate display area A1 is provided in which survey coordinate data of points (points A to C) set for each floor is displayed. In the upper right corner of the operation screen OP, a “read file” button B1 for reading a file as drawing data is provided.

On the lower left side of the survey coordinate display area A1 on the operation screen OP, with respect to the “floor coordinate plot”, a “similar shape check” button B2 and a “coordinate plot” button B3 located on the right side of the “similar shape check” button B2 And an XY survey coordinate display area A2 located below the “similar shape check” button B2 and the “coordinate plot” button B3.
A Z survey coordinate display area A3 is provided below the XY survey coordinate display area A2.
In the lower center of the operation screen OP, a survey data input area A4 for inputting survey coordinate data of survey (WGS-84) is provided. The survey data input area A4 includes a scale setting field R2 for designating the scale of the sketch, a point designation field R3 which is a pull-down menu for designating the point to be input, and an X survey coordinate input field for inputting the longitude of the survey with respect to the point. R4, a Y survey coordinate input field R5 for inputting a latitude, and a Z survey coordinate input field R6 for inputting a floor height (including the height of the ground surface) are provided. In the survey data input area A4, a point designation button B4 for designating a point on the sketch, and a “transition” button B5 for displaying the input survey values in the XY survey coordinate display area A2 and the Z survey coordinate display area A3. And are provided.

An operation method of the operation screen OP configured as described above will be described.
For example, in the case of plan view data generated by reading a paper drawing or by CAD drawing, a file of the floor plan G1 on the first floor is stored by pressing a “read file” button B1. 34 and read on the display means 33. At this time, the floor plan G1 on the first floor is displayed in a separate window.
Next, the scale of the sketch G1 on the first floor is designated by the scale setting field R2. Here, 1: 500 is specified. Next, by depressing the point designation button B4 and designating the point P11 of the first floor sketch G1 displayed in another window, the point P11 on the sketch G1 is designated as A point, and the coordinates corresponding to this A point Import (drawing coordinate data).
Next, survey values measured for the point P11 are input. As the survey value, for example, latitude, longitude, and height measured using a GPS surveying instrument are input.
Specifically, the longitude of the point P11 is input to the X survey coordinate input field R4, and the latitude is input to the Y survey coordinate input field R5. Next, the floor height is input to the Z survey coordinate input field R6.
When these are input, the survey value input in the X survey coordinate input field R4, the Y survey coordinate input field R5, and the Z survey coordinate input field R6 is displayed in the XY survey coordinate display area A2 by pressing the “Transition” button B5. Displayed by moving to the Z survey coordinate display area A3.
Similarly, after the points P12 and P13 are designated on the plan view G1, survey values are input corresponding to the points B and C.
Next, the “similar shape check” button B2 is pressed to check whether or not the designated drawing coordinate data and the survey coordinate data that is the survey value input are correctly input. Here, the survey value inspection will be described with reference to FIG. 8A and FIG.

As shown in FIG. 8A, when the “similar shape check” button B2 is pressed, virtual triangles formed by the survey coordinate data input corresponding to the points P11 to P13 in the sketch G1 are displayed at the points P11 to P13. It is determined whether or not it is similar to a virtual triangle formed by connecting each corresponding drawing coordinate data.
As a result, as shown in FIG. 8 (B), in the case where they are not similar, the facility data setting means 35h indicates the length (distance) between each of the points P11 to P13, and the scale indicating the scale of the sketch G1. Inspect based on data. That is, the actual distance is calculated from the length between the points P11 and P12 calculated based on the drawing coordinate data and the scale data, and the distance is the distance between the points P11 and P12 calculated based on the survey coordinate data. Whether it matches. Similarly, distances between the points P11 and P13 and between the points P12 and P13 are calculated. By doing so, in the example of FIG. 8B, it can be seen that the points P11 and P12 are the same, but the points P11 and P13 and the points P12 and P13 are different. Therefore, it can be determined that the position of the point P13 is not correct.

  However, even if it turns out that the position of the point P13 is incorrect, for example, after creating the sketch G1, if there is a shape change in the actual construction, or if the drawing coordinate data is simply input such as latitude / longitude input mistakes. It cannot be determined whether the position is shifted or the survey coordinate data is shifted. Therefore, the facility data setting unit 35h leaves the subsequent determination to the operator only by notifying the operator that the point P13 is incorrect as a message to the display unit 33.

When the survey value check is completed, the “coordinate plot” button B3 is pressed. By pressing this “coordinate plot” button B3, the facility data setting means 35h associates longitude coordinate data and latitude coordinate data with drawing coordinate data indicating the positions of the points P11 to P13 of the plan view data, The figure data is stored in the storage means 34 in association with survey coordinate data in which the floor height is the floor height data and scale data indicating the scale. And the value regarding each point P11-P13 is displayed on surveying coordinate display area A1.
By sequentially carrying out this procedure for all of the sketch drawings G1 to G4 from the first floor to the rooftop, the input (coordinate plot) of survey coordinate data relating to the building B is completed.

When the database of facility drawing data is constructed in the storage means 34 in this way, the rescue activity support device 3 can be used for rescue activities.
The conductor who arrives at the building B where the fire has occurred operates the rescue activity support device 3 to display the thumbnail screen shown in FIG. The control unit 35 displays the sketches G1 to G4 read from the storage unit 34 by the conductor's operation, the appearance photograph of the building B, the map image, and the like on the display unit 33 as thumbnails.

  When the conductor selects the floor plan G1 on the first floor from the thumbnail screen by the input unit 32, the control unit 35 reads the plan view data indicating the floor plan G1 from the storage unit 34. Then, the calculation means 35b of the control means 35 calculates the inclination of the plan view data indicating the sketch drawing G1.

  For example, it is assumed that the sketch drawing G1 is displayed on the display screen of the display means 33 as it is based on the longitude coordinate data and the latitude coordinate 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 (the latitudinal direction where the latitude increases or decreases) and the horizontal direction is the parallel direction along the parallel (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 that the building B is inclined with respect to the north. If it is constructed, the sketch G1 is displayed in an inclined state. In this case, not only the display of the building B and the character display are inclined, but also the degree of reduction of the entire rectangular sketch G1 needs to be increased, so that it is more difficult to see.

  A virtual straight line L1 (same as wall surface W1 in FIG. 10) connecting points P11 and P12 indicated by survey coordinate data (longitude coordinate data, latitude coordinate data) and a longitude direction of the survey coordinate system passing through point P11 (FIG. 10). Is calculated by the calculation means 35b using the angle formed with the phantom straight line L2 of the one-dot chain line as the correction angle θ, the slope of the sketch drawing G1 can be calculated.

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, based on the correction angle θ, the rotation means 35c rotates the plan view data indicating the sketch drawing G1 based on the drawing coordinate data of the points P11 and P12, thereby generating corrected plan view data which is the corrected sketch drawing G1. To do. 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.

Further, when rotating the plan view data, the rotating unit 35c generates the corrected plan view data at an angle obtained by adding the correction angle θ and the skew angle φ. By doing so, the plan view data read in a skewed state can be corrected. At this time, if the skew angle φ is a minus angle, the rotation angle becomes smaller than the correction angle θ by adding the correction angle θ.
When the corrected plan view data is generated, not only the plan view data is rotated, but also the display size is enlarged or reduced in accordance with the screen size (resolution) of the display means 33, so that it is possible to obtain a sketch that is easier to see.

  Next, the position display means 35e based on the longitude position data and the latitude position data among the position data received from the position communication device 2 via the wireless means 31 is displayed on the sketch G1 corrected as shown in FIG. Marks M1 and M2 indicating the position of the rescuer entering the building B are superimposed. The marks M1 and M2 are displayed according to the identification information from the identification information transmitting means 24 of the position communication device 2. When carrying out rescue activities, the fire brigade acts as a pair of rescuers and organizes the two groups as one team. There are two teams in the medium-scale fire brigade and more teams in the large-scale fire brigade. Therefore, although the number of rescuers entering depending on the scale of the fire is different, at least two rescuers will enter, so when the rescuer enters the building B, the position of each rescuer is commanded. It is desirable to be able to grasp.

  The sketch G1 shown in FIG. 11 is an example when two rescuers enter. In this case, the correspondence between the identification information assigned to each of the position communication devices 2 and the rescuer is taken in advance, whereby the star (☆) displayed as the mark M1 and the two displayed as the mark M2. A heavy circle (◎) is displayed on the display means 33. Therefore, it is possible to easily determine the positions of the two rescuers in the building B that is difficult to understand from the outside.

  By generating and displaying the corrected plan view data displayed as the sketch G1 corrected in this way, it is possible to display a plan view that matches the vertical and horizontal directions of the display screen. Therefore, the situation in the building B can be quickly grasped. Further, since the entire rectangular sketch G1 can be displayed on the entire rectangular display screen without waste, the degree of reduction can be minimized. Therefore, the rescue activity support device 3 can be accurately instructed by the conductor who supports the rescue activity from outside the building B.

  Next, when the conductor is notified that the rescuer confirms that there is no one in the office on the first floor, for example, with a transceiver carried by the rescuer, the conductor operates the input means 32. To fill the office on the first floor. In response to this instruction, the painting unit 35d paints the area S defined by the wall W, the door D, and the like with a color distinguishable from other rooms as shown in FIG. For example, if the sketch G1 is displayed on a white background with walls and characters displayed in black, it can be distinguished from other rooms by filling it with yellow as the color indicating confirmation.

  If the plan view data is CAD data, this fill will cover the area defined by the line data of the walls and doors. If the plan view data is image data read by the scanner, the wall or door By recognizing, it can be set as a determined range.

  In addition to painting the region S, a mark can be given to the region S in order to show that there is no one in the sketch. In the first embodiment, the conductor operates the input means 32 to designate the office on the first floor and instruct to give a mark. This designation may be made with a mouse or with a cursor key on the keyboard. In response to this instruction, the mark imparting means 35f superimposes the mark M3 with “certain” in ○ on the region S as shown in FIG. By giving the mark M3 to the region S in this way, not only can the same effect as that of the filling be obtained, but also data indicating the range of the region S can be obtained, for example, when plan view data is generated from a sketch drawing of a paper drawing. Even when it is difficult to set the range of the region S, it is possible to give a confirmation mark.

Whether the area S is filled by the filling means 35d or the mark M3 is given by the mark giving means 35f may be set so that only one of them can be used depending on the setting. May be selected.
In addition, a history (log) indicating that the painting unit 35d has confirmed that the painting has been performed or the mark imparting unit 35f has added the mark to the storage unit 34 by the painting unit 35d or the mark providing unit 35f. Is stored. The history may be the name of the monitor (name of the confirmer), the person responsible for granting, the confirmation time, the name of the disaster property, and the like.

  When the rescuer goes up to the second floor through the stairs K, the height position data out of the position data from the position communication device 2 exceeds the floor height data of the survey coordinate data associated with the floor plan G2 on the second floor. When the height determination means 35a determines that the height at which the rescuer is located is at the second floor position, the height determination means 35a instructs the calculation means 35b to calculate the degree of inclination with respect to the floor plan G2 on the second floor. Thereafter, similarly to the case where the first floor plan G1 is displayed, corrected plan view data of the second floor plan G2 is generated and displayed on the display means 33 as shown in FIG. By doing so, even if a rescuer moves to the second floor, the rescue operation can be performed accurately. If the two rescuers are divided into the upper and lower floors, the thumbnail screen shown in FIG. 9 is called instead of the second floor sketch G2 automatically switched by the movement of one rescuer, and the other rescuer is rescued. By selecting the floor plan of the floor where the person is located, it is possible to quickly grasp the position of the floor where the rescuer who wants to monitor is located.

In the rescue operation in the building B, not only a horizontal movement in which the rescuer moves on the same floor, but also a vertical movement in which the rescuer moves to the upper floor or moves to the lower floor is necessary. In such a case, when the position of the rescuer is to be displayed on the display screen together with the display of the building B, three-dimensional stereoscopic drawing data is used. For example, in the prevention system described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2007-11617), a computer reproduces image data based on basic data including 3D image data of a structure acquired using a 3D scanner. Software (program) for image creation is provided, and three-dimensional image data can be reproduced on a display. The image to be reproduced can be arbitrarily selected, for example, the entire building, an arbitrary height or an arbitrary height range (for example, a range of a height of 5 to 8 m from the ground surface) above, below, and sideways. , Reproduce an image viewed from an oblique direction, or specify and enlarge only a specific space area (specific room, corridor on a specific floor), and display the space area from any direction (angle) You can also Furthermore, the structure or structure portion displayed on the display can be rotated or moved in an arbitrary direction by rotating or moving the coordinate system (X axis, Y axis, Z axis) of the structure. Since the image data has color information and illuminance information in addition to the coordinate information, the image reproduced on the display is high-definition and realistic like a photographic image taken with a digital camera.
Thus, an apparatus that displays a three-dimensional solid drawing is required to have a high function and a considerably high processing speed.

  However, when the monitor tries to recognize the position of the monitored person using a three-dimensional solid drawing, lines representing structures on the back side and the near side overlap each other on the display screen and are difficult to recognize. In order to avoid this overlap, display processing such as coloring the wall or ceiling as a surface is necessary, so not only further image processing is required, but also a rescuer (monitored person) located on the other side of the wall Will be inconvenient. Therefore, as a position detection device, a conductor (monitor) can accurately grasp the position of a monitored person located in a building on a plurality of floors, and can display without delay even if it does not have high processing capability. Is desirable.

  The rescue operation support device, which is an example of the position detection device according to Embodiment 1 of the present invention, stores a floor plan for each floor as plan view data, and stores the floor height data associated with the plan view data. Is a floor plan automatically corresponding to the storage means 34, the height position data indicating the height of the rescuer R who is the monitored person, and the floor height data indicating the height of each floor. Height determining means 35a for selecting certain plan view data, and display means 33 by superimposing marks M1 and M2 indicating the position of the rescuer R on the selected plan view data based on the position data from the position communication device 2. Position display means 35e for outputting to the position.

  With this configuration, even when the building has two or more floors, the monitor can quickly grasp the position of the monitored person. Since the plan view data is two-dimensional plan data, the data capacity is smaller than that of the three-dimensional solid drawing. Therefore, the processing capability required for display need not be high. Moreover, the conductor who is the supervisor can immediately find the marks M1 and M2 indicating the rescuer R in the sketch.

  By making the floor plan data of each floor into a pseudo three-dimensional configuration, the height determination means 35a determines which floor the rescuer's height is based on the floor height of the floor plan data and the height position of the rescuer. Since it can be determined whether it is located, the floor plan of the floor where the rescuer is located can be selectively displayed automatically. Therefore, the rescue activity support system 1 according to Embodiment 1 can confirm the position of the rescuer intuitively and accurately.

As described above, according to the rescue activity support device 3 according to the first embodiment, it is possible to display the facility data in a state that is easy to see for the conductor using the plan view data indicating the floor plan of the building. In particular, the floor plan data that is the basis of the facility data can be used in a wide range because image data can be adopted by reading a paper drawing of a building with a scanner as well as drawing data drawn by CAD. In order to share information with local fire departments and other related organizations and to carry out quick rescue activities, the fire department headquarters sends the building's CAD data to educational institutions such as facilities and schools where care recipients are located. Is requested. However, it is possible to provide CAD data if it is newly constructed, but in the case of what was previously constructed, it is actually provided by paper drawings. That is, most are not digitized. Even in such a state, the rescue operation support device of the present invention uses the sketch data provided by the paper drawing by the scanner device as the plan data, and performs the rescue activity based on the plan data. By supporting, it can contribute to local fire fighting activities.
In the first embodiment, the correction angle θ with respect to the horizontal direction of the display screen is calculated as the inclination of the sketch G1 shown in FIG. 10. For example, the point P13 is on a virtual straight line parallel to the vertical direction of the point P11. The inclination of the sketch drawing G1 with respect to the vertical direction may be calculated.

In the first embodiment, the facility drawing data of the care facility is stored in the storage unit 34 in the rescue activity support device 3. Since each of the plan view data stored as the facility drawing data is two-dimensional drawing data, the data amount is smaller than the data of the three-dimensional solid drawing. Accordingly, since the transfer time is short, the facility drawing data is stored in the storage means of the computer installed in the fire headquarters H1 or the fire department H2, and the fire truck C equipped with the rescue operation support device 3 is dispatched. While moving, the facility drawing data relating to the building that has become the fire site may be transmitted from a computer installed in the fire headquarters H1 or the fire station H2 via the telecommunication line NW.
In addition, because the floor plan data, which is two-dimensional drawing data, has little data capacity, by transferring the facility drawing data to other organizations other than the Fire Department H1 and the Fire Department H2, And comprehensive rescue activities through collaborative work.
For example, in 3D 3D drawing data, the data capacity is large, and even if printed on a paper drawing, lines representing structures are overlapped on the back side and the near side. If you color the ceiling or the ceiling, you may not know the state of the room on the other side of the wall. If it is two-dimensional drawing data, the state in the facility can be easily grasped even if it is seen on the screen or a paper drawing.
In the rescue activity support system 1 according to the first embodiment, a mobile phone is used as the position communication device 2. However, in GPS positioning in a building, the GPS signal from the satellite is greatly attenuated. Therefore, there is a possibility that it cannot be received well. In that case, it is possible to specify the position of the rescuer R with higher accuracy by using AGPS (Assisted GPS).

(Embodiment 2)
Next, a position detection system according to Embodiment 2 of the present invention will be described based on FIG. 15 and FIG. FIGS. 15A to 15F are sketches from the first floor to the sixth floor of the factory showing an example of facility drawing data used in the position detection device of the position detection system according to the second embodiment. FIG. 16 is a sketch of the first floor in an inclined state.

  In the position detection system according to the second embodiment of the present invention, as the facility drawing data, the factory drawing is used as an example of the building as shown in FIGS. In addition to functioning as a rescue activity support system 1 in the same manner as in 1, whether the factory manager who becomes the supervisor is in a safe place or the employee who becomes the supervisor is evacuated in the event of a disaster or accident It functions as a safety management system for confirming. In addition, the position detection system can be used for factory managers to confirm the location of employees in a large factory even during normal times by using a floor plan of the factory with a wide monitoring range. .

  The facility drawing data includes at least two points on the plan view data shown in the sketch of the factory shown in FIG. 16, and the longitude and latitude of three points (points P51 to P53) shown in the drawing coordinate data in the second embodiment. And facility data associated with survey coordinate data indicating the height of each floor.

  An imaginary straight line (not shown) connecting the points P51 and P52 located at two corners in the left-right direction of the factory having a rectangular external shape in plan view coincides with the left-right direction on the sketch. In addition, a virtual straight line (not shown) connecting the points P52 and P53 located at two corners in the vertical direction coincides with the vertical direction on the sketch. Therefore, the correction angle can be calculated by the calculation means 35b based on the survey coordinate data (longitude coordinate data, latitude coordinate data) of the points P51 and P52 or the points P52 and P53 and the equation (1).

  When the correction angle is calculated by the calculation unit 35b, the rotation unit 35c generates corrected plan view data obtained by rotating the plan view data based on the correction angle, and a mark indicating the employee's position is given to the employee. Based on the position data from the carried position communication device 2, it is superimposed and output to the display means 33.

  In this way, in addition to using the facility drawing data as the nursing care facility shown in the first embodiment, the rescue operation support device 3 (see FIG. 3) can be managed safely by using a sketch of a facility such as a factory. Therefore, the factory manager can intuitively and accurately confirm the position of the employee.

(Embodiment 3)
Next, a position detection system according to Embodiment 3 of the present invention will be described with reference to FIG. FIG. 17 is a diagram illustrating a rescue activity support apparatus according to the third embodiment. In FIG. 17, components having the same configuration are denoted by the same reference numerals and description thereof is omitted.

  The rescue activity support system 1x according to the third embodiment includes, as the position communication device 20, an IC tag 2x carried by the rescuer R, a radio signal receiving device 2y installed for each predetermined range, and each radio signal reception A position transmission device 2z that transmits data indicating the position of the rescuer R from the device 2y to the rescue activity support device 3 is provided.

  The IC tag 2x can be an active RFID (Radio Frequency IDentification) with a built-in battery. The IC tag 2x has an output capable of communicating with the radio signal receiving device 2y of several tens of meters.

  The radio signal receiving device 2y is installed for each range where the position of the IC tag 2x can be specified. For example, the radio signal receiving device 2y is installed in each room on each floor, in a wide hall or factory, in each range where radio signals from the IC tag 2x can be received, so that the rescuer R is located in the building B. However, the wireless signal from the IC tag 2x can be received. The radio signal receiving device 2y receives a radio signal including identification information from the IC tag 2x carried by the rescuer R, so that the IC tag 2x of the rescuer R is in the same room, or from the IC tag 2x. That the wireless signal is within the receivable range is transmitted to the position transmitting device 2z.

  The position transmitting device 2z is communicably connected to each radio signal receiving device 2y installed in the building B and can communicate with the rescue activity support device 3 via the electric communication line NW (see FIG. 1). It is connected to the. The position transmitting device 2z receives position data (longitude position data, latitude position data, height position data) set in advance based on the position of the wireless signal receiving device 2y that has detected the IC tag 2x together with identification information of the IC tag 2x. To the rescue activity support device 3.

  In the first embodiment, the rescuer R carries the position communication device 2 and communicates directly with the telecommunications line NW. However, in indoor positioning, the GPS signal from the satellite is greatly attenuated. Therefore, there is a possibility that it cannot be received well. In the rescue activity support system 1x according to the third embodiment, the rescuer R receives the radio signal from the IC tag 2x carried by the rescuer R by the radio signal receiving device 2y installed in each room. Since the position of is specified, the communication state is not hindered.

  In the third embodiment, the position transmitting device 2z transmits position data set in advance for each radio signal receiving device 2y that detects the IC tag 2x to the rescue activity support device 3, so that the detectable accuracy is possible. As a room unit or a range with a radius of several tens of meters. Therefore, the radio signal receiving device 2y and the position transmitting device 2z can be realized with a simple configuration. However, if it is desired to detect the position of the rescuer R with high accuracy, the wireless signal receiving device 2y is provided with a function for detecting the distance to the IC tag 2x and the angle from the reference direction, so that any position in the room can be detected. It may be determined whether the rescuer R is present, and the position transmission device 2z may transmit the position data to the rescue activity support device 3 in correspondence with the position.

In the third embodiment, the active IC tag 2x is used. However, the passive IC tag 2x can be used as long as it can be detected by the wireless signal receiving device 2y. Furthermore, if the position of the rescuer R can be detected, it can be adopted in other indoor positioning systems.
Note that the rescue activity support system 1x according to the third embodiment can also function as a safety management system for the purpose of employee safety management, as in the second embodiment. When the rescue activity support apparatus 3 is caused to function as a device for safety management, the position transmitter 2z and the rescue activity support apparatus 3 do not have to be communicated by radio signals. Instead of 31, wired communication means may be provided.

  As described above, in the rescue activity support system 1x according to the third embodiment, the rescuer R carries the IC tag 2x in order to specify the rescuer R position, and the position of the IC tag 2x is a radio signal receiving device. By transmitting by 2y and the position transmitter 2z, the position of the rescuer R can be confirmed intuitively and accurately as in the rescue activity support system 1 according to the first embodiment.

(Embodiment 4)
A rescue activity support apparatus according to Embodiment 4 of the present invention will be described with reference to the drawings. FIG. 18 is a block diagram showing the configuration of the rescue activity support apparatus according to Embodiment 4 of the present invention. FIGS. 19A and 19B are diagrams for explaining the rotation of the survey coordinate system. In FIG. 18, the same components as those in FIG. 3 are denoted by the same reference numerals.

  The rescue activity support apparatus according to the fourth embodiment is characterized in that the coordinate axis of the survey coordinate system is rotated in accordance with the coordinate system of the plan view data.

  The building is not designed to coincide except when the north direction of the survey coordinate system represented by latitude and longitude coincides with the upward direction of the floor plan representing the building. For example, as shown in FIG. In many cases, it is in an oblique state with respect to the axial direction indicating latitude and longitude. However, the layouts G1 to G4 (see FIG. 4) showing the buildings are arranged in the vertical direction and the horizontal direction in the drawing in order to fit in the rectangular area. This is the same whether a paper drawing is created by hand or a drawing is created by CAD. Then, when displaying plan view data when a drawing is created by CAD, or plan view data generated by reading a paper drawing with a scanner device, one corner of this rectangular area, for example, the lower left, is a plan view. The data is displayed with the origin of the coordinate system, the horizontal direction as the X axis, and the vertical direction as the Y axis.

  Specifically, as shown in FIG. 19A, when the plan view data showing the floor plan G1 of the first floor of the building B is displayed on the display screen of the display means 33, the coordinate system of the plan view data is displayed. If the display is based on the coordinate axes (X axis, Y axis), the sketch G1 is displayed correctly.

  However, the survey coordinate system based on the latitude and longitude of the points P11 and P12 assigned as two points on the virtual straight line parallel to the up-down direction or the left-right direction of this sketch is used as the up-down direction and the left-right direction of the display screen, that is, drawing data. When the mark indicating the monitored person is superimposed on the displayed plan view data, the position of the monitored person is the position on the floor plan G1 and in the actual building B. May be displayed at a different position.

  In the rescue activity support apparatus 10 shown in FIG. 18, the calculating means 35b calculates a correction angle, and based on this correction angle, the rotating means 35cx rotates the coordinate axes of the survey coordinate system based on the coordinate axes of the coordinate system of the plan view data. Let

That is, the inclination of the virtual straight line L3 connecting the points P11 and P12 with respect to the longitude direction in the survey coordinate system is calculated as the correction angle θ based on the survey coordinate data. This correction angle θ can be calculated by the aforementioned equation (1).
Next, the rotation means 35cx rotates the coordinate axes (longitude direction and latitude direction) of the survey coordinate system based on the coordinate angle of the coordinate system of the plan view data based on the correction angle θ.
Then, the position display means 35e superimposes the mark M4 indicating the position of the monitored person on the plan view data based on the position data from the position communication device 2 (see FIG. 1) and outputs it to the display screen of the display means 33. To do.

  By doing so, the sketch G1 can be displayed in a state where the vertical direction and the horizontal direction of the sketch G1 coincide with the vertical direction and the horizontal direction of the display screen, and the mark M4 indicating the position of the monitored person is also rotated. Can be displayed according to the surveyed coordinate system. Therefore, since the supervisor can grasp the position of the monitored person accurately and quickly, the monitoring person who observes the monitored person from the outside of the building accurately recognizes the position of the monitored person. Can do.
