Description

[Technical field]

[0001] This relates to measuring the installation position of equipment installed in a building and setting information about the installed equipment. [Background technology]

[0002] Various equipment and devices are installed inside buildings. For example, electrical equipment, lighting equipment, air conditioning equipment, security equipment, disaster prevention equipment, computer network related equipment, etc. When designing a building, the location and wiring of each piece of equipment is recorded based on the architectural structural drawing, and an equipment drawing is completed. However, it is often the case that multiple identical related devices are installed in the same room, and mistakes such as mixing up equipment can occur when checking the installed equipment.

[0003] The following description will be given taking a fire alarm as an example. Fire alarm systems are equipment that detects fires occurring indoors and issues an alarm to encourage early extinguishing and evacuation. Fire alarm systems include fire detectors that detect smoke, heat, flames, etc., which are called smoke detectors, heat detectors, and flame detectors, respectively. All of the many installed fire detectors are connected to a receiver, which is an equipment control device, by a communication line, either directly or via a repeater, and some products have unique addresses to identify each fire detector connected to the communication line so that the receiver or repeater can recognize each individual fire detector. Hereinafter, the address refers to the information to identify each individual fire detector.

[0004] Generally, in order to make fire detectors versatile, they are not assigned addresses or are assigned dummy addresses when shipped from the factory. When designing the facility, the individual addresses are determined to suit the system, and when installing the fire detectors, the addresses are set using an address setting device or the like. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-166497 A [Patent Document 2] JP 2020-140451 A Summary of the Invention [Problem to be solved by the invention]

[0006] As mentioned above, in order to assign addresses to individual fire detectors, an address setting device is often used to set the address for each detector before operation. However, setting each detector one by one using the address setting device is a time-consuming and laborious process. In addition, mix-ups can occur when installing detectors after the addresses have been set.

[0007] As an alternative method, a method has been proposed in which the system automatically sets the addresses. However, even if the system automatically sets the addresses in the fire detectors, it does not mean that the addresses can be matched or linked between the actual locations of the fire detectors, the facility diagram, and the customer information of the receiver. The locations of the fire detectors and their addresses must be checked by humans one by one, which can lead to mistakes and trouble, lowering the reliability of the system and reducing work efficiency.

[0008] Patent Document 1, JP 2020-166497 A, describes a technology for automatically linking individual fire detector address settings with customer information. It describes how the location of the actually installed fire detector is collated with an equipment diagram using a GPS. However, it is often difficult to receive GPS accurately inside a building. On the other hand, in Patent Document 2, JP 2020-140451 A, a location identification system using a transmitter (beacon) is used to identify the location of a fire detector. However, this cannot be used in buildings where a location identification system using a transmitter is not installed.

[0009] Therefore, the present invention has been made in consideration of these points, and aims to provide a positioning device that can mechanically measure the numerical value of the installation position of actually installed equipment without using a GPS, beacon, etc., and furthermore, by comparing the measurement results of the installation position of the equipment with the installation position of the equipment on an equipment diagram, it is possible to identify and link the actually installed equipment with the equipment on the equipment diagram, thereby improving the efficiency of the setting work required for the equipment, eliminating setting errors, and improving the reliability of the system.

[Figure 9] FIG. 2 is a diagram showing an example of a mechanism for keeping the positioning device of the present invention horizontal; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Fig. 1 is an image of the positioning work for measuring the position of an equipment. The equipment in this case is an example of a fire detector of a fire alarm system. The positioning device 1 of the present invention is shown measuring the installation position of a fire detector 2A' directly below the fire detector 2A', which is the equipment intended to position.

[0027] FIG. 2 is a diagram showing the first embodiment, and is a diagram showing the configuration of a positioning device 1 according to the present invention. The positioning device 1 incorporates an electronic compass 10 and a range finder 11. The electronic compass 10 measures the angle between the earth's geomagnetic pole and the reference direction of the positioning device 1. The earth's geomagnetic pole is, for example, magnetic north. The range finder 11 measures the distance between the positioning device 1 and the wall of the room. In this embodiment, four range finders 11a, 11b, 11c, and 11d are installed in four directions at equal intervals. The four range finders 11 operate simultaneously to measure the distance to the wall in four directions (distance measurement a, distance measurement b, distance measurement c, and distance measurement d). Five pieces of measurement data, namely the angle between the earth's geomagnetic pole and the reference direction of the positioning device 1 and the distance to the wall in four directions, are stored as one set, and the five pieces of measurement data can be transmitted to other devices via a communication circuit. In FIG. 2, four range finders are used to measure the distance in four directions, but distance measurement in three directions may be performed using at least three range finders.

[0028] FIG. 3 shows the principle of measuring the angle between the earth's geomagnetic poles and the reference direction of the positioning device 1, and the distances from the positioning device 1 to the inner walls of a room in four directions (distances a, b, c, and d).

[0029] The electronic compass 10 is equipped with a magnetic sensor that detects the very weak geomagnetic field that surrounds the Earth, and this sensor is able to detect the direction of north (magnetic north), making it possible to measure the angle at which the reference direction of the positioning device 1 faces, whether north, south, east or west. In reality, there is a slight deviation between magnetic north indicated by the Earth's geomagnetic poles and true north on a map. Generally, true north is indicated by a direction arrow on architectural and facility diagrams. There is information (from the Geospatial Information Authority of Japan) that the deviation in Tokyo at the time of filing this application was approximately 7 degrees 40 minutes. This deviation can be corrected to true north if the latitude and longitude of the building in question are known.

[0030] A laser rangefinder can be used as the rangefinder 11. A laser rangefinder measures the distance between the laser rangefinder and an object by emitting laser light and receiving the reflected light that occurs when the light hits the object. Generally, there are two methods for measuring distance using laser light: the phase difference distance method and the pulse propagation method.

[0031] The actual location measurement and comparison with facility diagrams will be described below. Here, the floor plan shown in equipment diagram 4 of Fig. 3 shows an example of use in room D on the 8th floor. The direction of the 8th floor differs from the direction shown by the azimuth arrow. There are four rooms on the 8th floor, from room A to room D, and one or two fire detectors 2 are installed in each room. An address is written next to each fire detector to identify the individual fire detector, given by the designer, and is written as 80H to 84H, respectively. This address is only written on the equipment plan, and is not yet set in the actually installed fire detectors, so an example will be explained to measure the position of fire detector 2A' in room D.

[0032] The actual installation positions of the fire detectors are shown in an actual room (room D) 4'. The actual room (room D) 4' is rectangular and surrounded by four walls 4a, 4b, 4c, and 4d, and two fire detectors 2A' and 2B' are installed on the ceiling. Here, the installation position of the fire detector 2A' is measured as an example.

[0033] First, the positioning device 1 is held directly under the fire detector 2A'. When the positioning device 1 receives a measurement start trigger from an operation unit (not shown) of the positioning device 1, the four laser distance meters 11a, 11b, 11c, and 11d simultaneously measure the distances to the walls 4a, 4b, 4c, and 4d in the four directions, and the electronic compass 10 measures the angle (direction) of the positioning device 1 with respect to the magnetic pole. These five measurement data are transmitted to an external device (for example, the fire alarm server 22 in FIG. 4). Transmission to the fire alarm server 22 may be relayed through a tablet terminal 20 or the like held by an operator and connected to the Internet 23. The fire alarm server 22 stores at least an equipment diagram of the building (for example, CAD data of the equipment diagram 4).

[0034] The fire alarm server 22 refers to the CAD data of the equipment diagram 4 of the room D on the 8th floor of the building, and calculates the position of the positioning device 1 in the room D from the received five measurement data, i.e., the reference direction of the positioning device 1 and the distances to the walls 4a, 4b, 4c, and 4d of the room D in the four directions (distance measurement a, distance measurement b, distance measurement c, and distance measurement d). At this time, since the position measurement is performed directly under the fire detector 2A', the actual installation position of the fire detector 2A' on a flat surface in the room D is known. Note that it is necessary to notify the fire alarm server 22 of the building name, floor number, and room name in advance before the measurement. For example, if the equipment diagram 4 of the building is downloaded to the tablet terminal 20 owned by the worker and made available for display, the fire alarm server 22 may be notified by tapping the corresponding floor number and room name.

[0035] The fire alarm server 22 is assumed to incorporate software capable of recognizing the walls 4a, 4b, 4c, and 4d of each room depicted in the equipment diagram 4 and the coordinates on the equipment diagram 4 of the fire detectors 2 installed in each room. The software may be based on machine learning.

[0036] A method for identifying the location of the actually installed fire detector 2A' as the facility device (fire detector 2A) shown in the facility diagram 4 using the above five pieces of measurement data will be described below. A reference direction of the positioning device during positioning is determined from measurement data of an electronic compass; On the equipment diagram 4, by obtaining a position that matches the distance to the wall in the room on the equipment diagram 4 from the reference direction of the positioning device 1 and distance data in a plurality of predetermined directions, the equipment device (2A') described in the obtained position can be identified as the fire detector 2A described in the equipment diagram 4. Of course, there is a slight error between the position of the fire detector 2A on the equipment diagram and the position of the detector 2A' that is actually installed, so a logic that takes the error into account is required to identify the fire detector 2A described on the equipment diagram. For example, a method of identifying the corresponding fire detector 2 by plotting the obtained equipment position on the equipment diagram 4 and finding the fire detector 2 described within a radius of 0.5 m from the plot position may be used.

[0037] Since the located fire detector 2A' matches the fire detector 2A on the equipment diagram and can be identified, it is possible to obtain equipment information such as the address of the fire detector 2A described on the equipment diagram. In this example, it is clear that the address, which is the equipment information of the identified fire detector 2A, is 83H. Note that 83H is the expression when the address is expressed in hexadecimal, and in this case, 256 different addresses from 00H to FFH (0 to 255) can be expressed. Of these 256 different addresses, for example, 00H may be used as a dummy address indicating that no address has been set. This address may be expressed in three or more digits depending on the model of the equipment's fire alarm system.

[0038] The significance of measuring the location of equipment and understanding the installation positions of the equipment within a room will be explained below. For example, when designing a fire alarm system S, the required number of equipment (e.g., fire detectors) is placed on the architectural structural drawing (structural information) of the building based on information such as the room's purpose, shape, and floor area, and other information is then placed in the most optimal locations to complete the structural drawing. Note that the architectural structural drawing also includes drawings of the walls separating the rooms, the pillars within the rooms, and other structures within the rooms.

[0039] In the case of fire detectors with addresses that can be set arbitrarily, it is common to set and record the detector addresses in the equipment diagram according to the system. After the equipment diagram is completed, the fire detectors shown on the diagram are installed in the designated locations on the ceiling of each room as shown on the diagram. At this time, the address of each fire detector is set manually using an address setting device before installation. Once installation is complete, a detector tester is used to test the operation of each installed fire detector, and it is confirmed that the receivers issue and display alarms for all fire detectors as shown on the diagram, completing the fire alarm system S.

[0040] As described in the problem to be solved by the invention, manually setting the address for each fire detector while looking at the equipment diagram as described above is a cause of mistakes and trouble, lowering the reliability of the system and reducing work efficiency. Therefore, by mechanically and reliably matching the installation positions of the equipment devices shown on the equipment diagram with those actually installed, it becomes possible to automatically set equipment information such as the address of each fire detector.

[0041] FIG. 4 shows an example of the operation from determining the installation location of a fire detector in a fire alarm system S to setting the address of the fire detector. This is an example of how to reliably set the address of a fire detector shown on an equipment diagram to the fire detector that is actually installed.

[0042] The following is a step-by-step explanation. Note that Fig. 4 shows an example in which the positioning device 1 is combined with a detector tester 3 that tests the operation of the fire detector 2. The positioning device 1 may be used in combination with other devices in this way according to the purpose, or may be used alone.

[0043] First, a facility diagram of the building stored in the fire alarm server 22 is downloaded to the tablet terminal 20, and the floor in question (the 8th floor in this example) is displayed. If possible, it would be better to receive fire information from the fire alarm server 22 at any time and display the operating status of each fire detector 2, which would allow the operation to be checked as work proceeds, improving the reliability of the work.

[0044] The location where the work will be performed, that is, the building information, floor number, and room name, is transmitted from the tablet terminal 20 to the fire alarm server 22. Through this operation, the fire alarm server 22 prepares an equipment diagram of room D on that building and that floor, and transmits the equipment diagram of that room D to the tablet terminal, and the equipment diagram including room D is displayed on the tablet terminal. Here, it is possible to specify the specific fire detector 2 displayed on the tablet 20 with the tablet terminal's touch pen or the like, and obtain the equipment information from the server 22, but this method is not adopted in the present application because there is a possibility of mistakes being made when specifying the equipment with the touch pen.

[0045] The detector tester 3 with the positioning device 1 attached is held directly under the detector 2' (2A') to be addressed, and is operated by an operation unit (not shown) of the positioning device 1. The positioning device 1 first sends measurement start information, which is a signal to start measurement, to the server via the tablet 20, and then measures the position of the equipment by the operation of FIG. 3, and sends positioning data (five measurement data in this case) to the fire alarm server 22 via the tablet terminal 20. The positioning device 1 is set so that it can send and receive wireless signals with the tablet terminal 20 via Bluetooth (registered trademark) or WiFi (registered trademark). The positioning device 1 may be configured to use a 4G or 5G mobile communication system so that the positioning device 1 communicates directly with the fire alarm server 22. The fire alarm server 22 sends the measurement start information received from the positioning device 1 to the receiver 21, and further stores the positioning data received thereafter. The time of reception may also be stored at the same time.

[0046] In FIG. 4 (1), at the same time as (or before or after) determining the location of the facility device, the detector tester 3 is activated for the fire detector 2' (2A') and pseudo-fire information (smoke or heat, etc.) is sent to the fire detector 2' (2A'), causing it to activate as a fire alarm.

[0047] At (4), the fire detector 2' (2A') sends the activation information to the receiver 21, which is responsible for various controls of the equipment, via the communication line 24. The activation information is fire data including a signal indicating that there is a fire. The fire data may refer to smoke density and temperature. In normal operation, the fire detector 2' (2A') would send its own address and fire data to the receiver, but in this case, since an address has not yet been assigned, the fire detector 2' adds a unique code instead of the address and sends it out. The unique code possessed by the fire detector 2 is, for example, a unique code assigned at the time of production in a factory, and may be a number specific to the detector, a unique manufacturing number, or a code according to a predetermined rule that is determined independently.

[0048] After receiving the measurement start information from the server 22, the receiver 21 receives and stores the operation information and the unique code from the fire detector 2 at (4'). Here, the time of reception may also be stored at the same time.

[0049] Meanwhile, the fire alarm server 22 compares the five pieces of positioning data (the reference direction of the positioning device, the distances to the four walls) sent in (2) with the equipment diagram of the specified room D, and identifies the fire detector 2 (2A) on the equipment diagram. It obtains equipment information including the address (83H) of the identified fire detector 2 (2A) from the equipment diagram, and sends it to the receiver 21 in (3). The receiver 21 and fire alarm server 22 are connected via the Internet 23 or a LAN.

[0050] In (5), after receiving the measurement start information from the server 22, the receiver 21 regards the address (83H) of the fire detector 2 (2A) received from the fire alarm server 22 in (3) and the unique code of the fire detector 2' (2A') received in (4') after similarly receiving the measurement start information from the server 22 as the same, and stores them in association with each other. As a result, preparations are completed for reliably setting the address of the fire detector 2 (2A) written on the equipment diagram to the fire detector 2' (2A') that is actually installed.

[0051] At this time, after receiving the measurement start information, each received information is recognized (linked) as information of the same facility device, but the time when the receiver 21 received the alarm information from the fire detector 2 and the time when the server received the positioning data can be compared and used as a standard for determining that they are the same. This means that the receiver has completed linking the unique code of the fire detector 2 with the address of the fire detector 2. The linking work may be performed by the fire alarm server 22.

[0052] In (7), the linking information may be shared with the server by returning the alarm information of the fire detector 2 that was deemed to be the same (linked) in the above-mentioned (5) to the fire alarm server 22. Next, the fire alarm server 22 sends the fire detector 2 alarm information to the tablet terminal 20, so that the worker can confirm on the tablet that the detector 2 that triggered the alarm is the same as the detector 2' that has been located and tested for operation.

[0053] At (6), the receiver 21 receives the alarm information and sends the unique code, the address to be assigned, and the command signal to be assigned to the actual fire detector 2' (2A') installed in the room D that has been linked. At (6'), the fire detector 2' detects its own unique code in the signal from the receiver 21 and simultaneously confirms the command to assign the address, and stores the address added to the signal as its own address, and thereafter communicates with the receiver 21 using this stored address.

[0054] As a result, the address (83H) of the fire detector 2 (2A) shown on the facility diagram can be reliably set to the fire detector 2' (2A') that is actually installed. Incidentally, since the unique code has far more digits than the address and is not suitable for normal communication between the receiver 21 and the fire detector 2', an address with fewer digits is generally used.

[0055] The above is the procedure for setting the address of the fire detector 2' using the positioning device 1, and by repeating the same procedure for the other fire detectors 2' in sequence, assignment of addresses to all the fire detectors 2' is completed.

[0056] Fig. 5 shows an example of the structure of an apparatus that combines the existing sensor tester 3 and the positioning device 1 used in Fig. 4. Before explaining the structure, the general sensor test procedure will be explained below. An operation test is performed on the fire detector 2 installed on the ceiling surface using a detector tester 3. The detector tester 3 is equipped with a device that generates smoke and heat to create a pseudo fire that activates the fire detector 2. The detector tester 3 is placed over the bottom of the fire detector, and smoke and heat are sent to the fire detector 2 according to the type of fire detector 2. When exposed to smoke or heat, the fire detector 2 determines that there is a fire and sends a fire signal to the receiver or repeater, and the operation of the fire detector and the system are tested by checking the fire signal. Since the fire detector is installed on the ceiling surface at a height of about 3 to 4 m (or more), the detector tester 3 is attached to the tip of a 2 to 3 m (or more) rod, and an operator holds and operates the rod, covers the fire detector 2 on the ceiling surface with the detector tester 3, and performs an operation test by sending smoke and heat into it. Note that the rod is omitted in Figure 5.

[0057] Next, the sensor tester 3 shown in Fig. 4 will be described with reference to Fig. 5. Fig. 5 is a diagram in which the sensor tester 3 and the positioning device 1 are combined. Each will be described separately. The figure shows a vertical cross-sectional view of a typical detector tester 3. It is cup-shaped with an opening 14 on the top surface. The opening 14 has a diameter and volume that allows the fire detector 2 to be tested to fit snugly inside. Inside the detector tester 3 is a smoke or heat generator 12, and nearby is a blower fan 13 driven by a motor (not shown). The smoke or heat generated by the smoke / heat generator 12 is agitated and moved inside the detector tester 3 by the fan, and is efficiently sent to the fire detector 2.

[0058] Next, a cross-sectional view of the positioning device 1 will be described. The positioning device 1 attached to the underside of the detector tester 3 is shown in a vertical cross section as described in FIG. 2. The laser range finder 11 faces left and right. There are two other sets of laser range finders. There is a control circuit 31 near the center. The control circuit 31 is equipped with a microprocessor and its control program to control the four sets of laser range finders 11, the electronic compass 10, the operation unit / display unit 32, and the communication circuit 31. In addition, a power supply unit 33 (not shown) is installed and supplies power to each device of the positioning device 1. Since the positioning device 1 is portable, the power supply unit 33 consists of a rechargeable battery and a constant voltage power supply unit.

[0059] 6(a), 7, and 8(b) show a method in which only one set of laser rangefinders 11 is used and the laser rangefinders 11 are rotated in a plane by 360°. Hereinafter, a description will be given of Example 2, which is a rotary positioning device that functions even with only one set of laser rangefinders 11. The laser range finder is rotated 360° by a rotary drive mechanism 34 (not shown), thereby continuously measuring the distance to the wall inside the room. By continuously measuring, the shape inside the room can be grasped. The hatched part in FIG. 6(b) shows an exaggerated depiction of the measured shape including measurement errors. If there are windows, curtains, etc. in the room, the measurement error may be large, and an example of a shape including such errors is shown. The electronic compass 10 measures the angle between the reference direction of the positioning device 1 and the Earth's geomagnetic pole (e.g., magnetic north), and can grasp the reference direction in which the positioning device 1 is facing.

[0060] The electronic compass 10 may be rotated together with the laser rangefinder 11, or the electronic compass 10 may be installed in a non-rotating part. When the electronic compass is installed in a non-rotating part, a rotary encoder 35 is required. The rotary encoder 35 is a device that measures the angle by which the laser rangefinder 11 has rotated relative to the reference direction of the positioning device. By linking the rotary encoder 35 and the laser rangefinder 11 to perform continuous measurements, it is possible to obtain data that can grasp the shape of the inside of a room, such as the hatched area in Figure 6(b) above.

[0061] When the electronic compass 10 and the laser range finder 11 are fixed to the same rotor 16 and rotated simultaneously, the electronic compass 10 and the laser range finder 11 are linked to perform continuous measurements, thereby obtaining data that can grasp the interior shape of the room as described above. Also, the rotary encoder can be omitted, which reduces costs.

[0062] FIG. 7 is a diagram showing the concept of the structure of the rotary positioning device 1. The device is composed of a base 15, a rotor 16, a spacer 17, and a top plate 18. The base 15 has a structure that can be connected to a support rod (not shown), and is equipped with a rotary drive device 34 that rotates the rotor 16 described below, a rotation angle measuring device (rotary encoder 35) that measures the rotation angle of the rotor, a control device 30, a power supply device 33, a communication device 31, and an operation unit / display unit 32. The operation unit / display unit 32 may be a separate unit. The rotor 16 is configured to rotate by the drive device of the base 15, and a laser range finder 11 is mounted on the rotor 16 and rotates in the horizontal direction together with the rotor 16 to continuously measure distances. The distance may also be measured at positions of a plurality of predetermined rotation angles. The spacer 17 is a structure that fills the gap between the rotor 16 and the top plate 18, and may rotate together with the rotor 16. The top plate 18 is fixed to a non-rotating portion of the base 15, and may have a structure that allows it to be connected to other devices such as the sensor tester 3, if necessary.

[0063] FIG. 8(a) is a block diagram showing the first embodiment. The four laser distance meters 11-1 to 11-4 are installed facing different predetermined directions, and are devices that measure the distance from the positioning device 1 to the walls in the room in each predetermined direction. The electronic compass 10 is a device that measures the angle between the reference direction of the positioning device 1 and the earth's geomagnetic pole. The communication circuit 31 is a wireless communication device for sending each measurement value measured by the positioning device 1 to the server 22. It may be directly connected to the Internet 23, or, for example, it may be connected to the tablet 20 via Bluetooth (registered trademark) or the like, and each measurement value data may be sent from the tablet to the fire alarm server 22. The operation unit / display unit 32 is a device that can operate and display the positioning device 1, and the operation unit is composed of a touch panel and switches, and the display unit is composed of an LCD, LED, etc. These components perform operations and displays required for handling the positioning device 1. The power supply circuit 33 is a device that supplies the power required for each part of the positioning device 1, has a rechargeable battery to make the positioning device 1 portable, and has a circuit that can supply the voltage and current required for each device. The control circuit 30 is a device that controls each of the above-mentioned devices, and is a so-called computer that has a CPU, memory, I / O, timer, etc., and stores in the memory a program in which the control procedures required for the operation of the positioning device 1 are written. The CPU executes the program and controls each part using the I / O and timer.

[0064] Fig. 8(b) is a block diagram of the second embodiment. Although there are some differences from Fig. 8(a), the rest are the same. Only the differences from Fig. 8(a) will be described below. The pair of range finders 11 are devices that measure the distance between the positioning device 1 and the walls in the room. They are rotated 360° horizontally by the rotary drive device 34 to continuously measure the distance between the positioning device 1 and the walls in the room. Alternatively, a plurality of predetermined directions may be measured at a predetermined rotation angle. The rotary encoder 35 continuously measures the rotation angle of the range finder 11 rotated by the rotary drive device 34 and the positioning device 1 relative to a reference direction in conjunction with the range finder. The rotary encoder may be replaced by the electronic compass 10. The electronic compass 10, communication circuit 31, operation unit / display unit 32, power supply circuit 33, and control circuit 30 are the same as those in FIG. 8(a).

[0065] 9 is a diagram showing the use of the positioning device 1 with a horizontal maintenance device 40 having a mechanism for always keeping it horizontal. The positioning device 1 is a device that should be used horizontally. If it is used in a state tilted from the horizontal, there is a risk that the distance between the positioning device 1 and the wall of the room cannot be measured accurately. Therefore, it may be combined with a mechanism for keeping the positioning device 1 horizontal.

[0066] As an example of the horizontal maintenance device 40 that is a mechanism for keeping the positioning device 1 horizontal, an example using a device called a two-axis gimbal or two-axis stabilizer will be shown. The holding rod 44, which is the handheld part of the horizontal maintenance device 40, and the holding part 43 are fixed. An arm 43a that holds the roll axis 41a is fixed and extends from the holding part 43, and the roll axis 41a is fixed to the other end of the arm 43a. A roll axis motor (not shown) that controls the roll axis is built into the roll axis 41a, and a roll axis rotation part 41b is attached so as to be able to roll rotate. A roll axis arm 41c is connected to the roll axis rotation part 41b, and a pitch axis 42a is fixed to the other end. A pitch axis motor (not shown) is built into the pitch axis 42a, and a pitch axis rotation part 42b is attached so as to be able to pitch rotate. A pitch axis arm 42c is attached to the pitch axis rotation part 42b. A connection base 45 to which various devices are attached is fixed to the other end of the pitch axis arm 42c. A two-axis gyro sensor (not shown) is built into the connection base 45.

[0067] The inclination with respect to the horizontal is constantly measured by a two-axis gyro sensor, and a feedback control signal is sent to the roll axis motor and pitch axis motor to control horizontal maintenance, thereby maintaining the horizontality of the equipment attached to the connection base 45. By attaching the positioning device 1 to the connection base 45, it becomes possible to correct shaking caused by the inclination of the holding rod 44 and shaking of the hand holding it, and the positioning device 1 can always remain horizontal.

[0068] Although a two-axis gimbal is used to correct the horizontal position of the positioning device 1, a correction device capable of correcting the vertical direction may be added to the two-axis gimbal to prevent shaking in the vertical direction.

[0069] The positioning device 1 of the present invention does not measure the height direction because its purpose is to measure the position of equipment on the floor of a room. However, by adding a range finder for the downward or upward direction, or for the up and down directions, it is possible to measure the installation height of the target equipment. For example, by adding a range finder for the up and down direction in addition to the four directions on the floor, making it possible to measure six directions, it becomes possible to obtain three-dimensional position information of the equipment relative to the room.

[0070] Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. All or part of the device can be configured by distributing or integrating functionally or physically in any unit. For example, the range finder 11 has been described as a device that measures distance using a laser, but distance may be measured using other methods such as sound waves or radio waves. In addition, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effect of the new embodiment resulting from the combination combines the effect of the original embodiment. [Explanation of symbols]
