[0021] The embodiment of the present invention will be described with reference to the accompanying drawings. In addition, in each figure, the same or corresponding parts are marked with the same reference numerals, and the repeated description of the parts is appropriately simplified or omitted.

[0022] Implementation Method 1

[0023] Figure 1 This is a structural diagram of a system to which the in-building information management device in the first embodiment is applied.

[0024] exist Figure 1 In the system, a plurality of application software 1 provides an interface to a user 2. The plurality of application software 1 implements various services.

[0025] For example, the in-building information management device 3 is installed inside the building as an on-premises deployment. For example, the in-building information management device 3 is installed outside the building as a cloud.

[0026] The in-building information management device 3 includes a device communication unit 4 , an application communication unit 5 , various information storage units 6 , and various calculation units 7 .

[0027] The device communication unit 4 communicates with various devices within the building. For example, the device communication unit 4 communicates with the elevator equipment 8, air conditioning equipment 9, ventilation equipment 10, access control equipment 11, and lighting equipment 12. For example, the device communication unit 4 communicates with electrical, gas, and water meters 13, surveillance cameras 14, imaging devices 15, robots 16, mobile devices such as electric wheelchairs 17, portable terminals such as smartphones 18, and various sensors such as human sensors 19. For example, the device communication unit 4 communicates with high-voltage power connection equipment 20. The device communication unit 4 collects information such as the location, operating status, and energy consumption of the devices. The device communication unit 4 transmits information regarding the call to the elevator equipment 8, robot 16, mobile device 17, smartphone, etc., information regarding start or stop requests, and information regarding target values ​​for temperature, humidity, wind speed, illumination, etc. to the devices.

[0028] The application communication unit 5 communicates with the plurality of application software 1. The application communication unit 5 outputs information necessary for realizing a service to the application software 1. The application communication unit 5 receives information regarding a request to a device from each of the plurality of application software 1.

[0029] The various information storage unit 6 stores various information. For example, in addition to storing current values ​​and history information collected from devices, the various information storage unit 6 also stores map information within a building. For example, the various information storage unit 6 stores information received by the application communication unit 5.

[0030] The various calculation units 7 perform various calculations. For example, the various calculation units 7 uses the information stored in the various information storage units 6 to calculate the location of a person, various predicted values, estimated values, and determined values. For example, the various calculation units 7 causes the various information storage units 6 to store the calculation results. For example, the various calculation units 7 determines whether a request to a device is permitted based on information from other application software 1 and the device, and then transmits the information to the device as needed.

[0031] Next, use Figure 2 The main parts of the in-building information management device 3 will be described.

[0032] Figure 2 This is a configuration diagram of the main parts of the in-building information management device in the first embodiment.

[0033] like Figure 2 As shown, in the in-building information management device 3 , the equipment, the robot 16 , the mobile device 17 , the portable terminal 18 , and the portion related to the position information of people function as a position management device 21 .

[0034] In addition, "position information" is information including the identifier of the positioning object such as the robot 16, the variable indicating the position of the positioning object, and the date and time when the positioning object is located at the position. In the case where the positioning object is not determined, there may be no information on the identifier of the positioning object. For example, the variables indicating the position of the positioning object are the three variables of the horizontal two axes (x, y) and the height (z) in rectangular coordinates. For example, the variables indicating the position of the positioning object are the three variables of latitude, longitude, and altitude. For example, the variables indicating the position of the positioning object are the three variables of the radius vector r and two deflections in spherical coordinates. For example, the date and time when the positioning object is located at the position is year, month, day, hour, minute, and second. The date and time when the positioning object is located at the position may also include values ​​less than seconds.

[0035] The position management device 21 includes a relationship storage unit 22 , a communication unit 23 , a position information storage unit 24 , a usage information determination unit 25 , an order determination unit 26 , a weight determination unit 27 , a position determination unit 28 , a positioning target position storage unit 29 , and a map mapping unit 30 .

[0036] The relationship storage unit 22 stores information about the relationships between multiple positioning devices 31 and the objects being positioned. The positioning devices 31 are devices capable of acquiring position information related to the objects being positioned. Examples of positioning devices 31 include elevator equipment 8, access control equipment 11, lighting equipment 12, surveillance cameras 14, beacons, human sensors, and PDRs.

[0037] The communication unit 23 receives position information of the target object from each positioning device 31. The position information storage unit 24 stores the position information received by the communication unit 23. For example, the position information storage unit 24 stores the date and time information of the identifier of the target object and the variable information indicating the position of the target object transmitted from each positioning device 31 as the date and time information of the target object's location. For example, the position information storage unit 24 stores the date and time information of the identifier of the target object and the variable information indicating the position of the target object received by itself as the date and time information of the target object's location.

[0038] At the time of determining the position information of the positioning target, the utilization information determination unit 25 determines the position information from each positioning device 31 to be used in determining the position information of the positioning target.

[0039] The order determination unit 26 determines the order of the positioning objects used to determine the position information. For example, the order determination unit 26 determines the order of the positioning objects used to determine the position information using the number (n) of position information used when determining the position information. For example, the order determination unit 26 determines the order of the positioning objects used to determine the position information in descending order of the time (tm) of the used position information and the time (td) of the position information to be determined. For example, the order determination unit 26 comprehensively considers the number (n), the time (tm), and the time (td) and determines the order of the positioning objects used to determine the position information in ascending order of the evaluation value order shown in the following formula (1).

[0040]

Mathematical formula 1

[0041] order=α×(1 / n)··+··+β×(∑『tm-td]) / n (1)

[0042] In addition, in formula (1), α and β are weight coefficients.

[0043] The position determination unit 28 determines the position information of the object to be measured using the following equations (2), (3), and (4). At this time, the position information of the object to be measured is represented by variables (x, y, z). The position information (x m ,y m , z m ) corresponds to the variables (x, y, z).

[0046]

Mathematical formula 3

[0047]

[0048]

Mathematical formula 4

[0049]

[0050] In addition, in formula (2), a m is the location information x m The weight coefficient of . In formula (3), b m is the location information y m The weight coefficient of . In formula (4), c m is the location information z m The weight coefficient of .

[0051] Weight coefficient a m The following formula (5) is satisfied.

[0054] Weight coefficient b m The following formula (6) is satisfied.

[0055]

Mathematical formula 6

[0056]

[0057] Weight coefficient c m The following formula (7) is satisfied.

[0058]

Mathematical formula 7

[0059]

[0060] These weight coefficients are determined by the weight determination unit 27. If the weight coefficient is set to 0, the position information of the corresponding positioning device 31 is not used. The value of the weight coefficient may be fixed or may be dynamically changed.

[0061] The position information of the determined positioning target is stored in the positioning target position storage unit 29. At this time, the map mapping unit 30 may correct the position information of each positioning device 31 using the map information of the building.

[0062] Next, use Figure 3 The method for determining the information to be used is explained.

[0063] Figure 3 A determination method based on the usage information of the in-building information management device in the first embodiment will be described.

[0064] like Figure 3 As shown, as the time td to be determined, when a future time tf or a past time tb is set relative to the positioning time point, the position information b1 measured by the positioning device 31 of B, the position information c1 measured by the positioning device 31 of C, and the position information d1 and d2 measured by the positioning device 31 of D are used.

[0065] Furthermore, tf and tb may be different values ​​for each positioning device 31. The timing for determining the position information of the positioning target may be a timing at a constant interval every second or an arbitrary timing starting from a predetermined event.

[0066] Next, use Figure 4 A first example of a method for determining weight coefficients will be described.

[0067] Figure 4This is a diagram for explaining a first example of a method for determining a weight coefficient by the in-building information management device in the first embodiment.

[0068] like Figure 4 As shown in FIG, when the position information is within the exclusive area of ​​the position information of another positioning object, the weight coefficient may be made smaller so as to reduce the influence of the position information. For example, if the position information of positioning object a is at a distance d from the position information of other positioning object b, and the exclusive area of ​​positioning object b is defined by a radius r, then the weight coefficient before the change is a. mb 、b mb 、c mb , the weight coefficient after the change is a ma 、b ma 、c ma When the weight coefficient a is changed ma 、b ma 、c ma The calculation is performed according to the following equations (8) and (9).

[0069]

[0072]

[0073] On the other hand, when the weight coefficient is determined so as to increase the influence of the position information at a time close to the position information to be determined, the weight coefficient a after the change is ma 、b ma 、c ma The calculation is performed according to the following equations (10) and (11).

[0074]

Mathematical formula 10

[0075]

[0076]

Mathematical formula 11

[0077]

[0078] Next, use Figure 5 A second example of the method of determining the weight coefficient will be described.

[0079] Figure 5 This is a diagram for explaining a second example of the method for determining the weight coefficient by the in-building information management device in the first embodiment.

[0080] like Figure 5As shown, when the position information of another target is measured near the target, the weight coefficient can be determined to minimize the influence of the position information of the undetermined target. For example, when determining the position information of target A, when using the position information J of the undetermined target, there may be position information K associated with another target B within the time range of the use of the information. In this case, if the distance q between position information J and position information K is less than Q, the weight coefficient for position information J is calculated according to the following equations (12) and (13).

[0081]

Mathematical formula 12

[0082]

[0083]

Mathematical formula 13

[0084]

[0085] Here, Q is a value that defines the distance range that affects the position. For example, Q can be determined based on the positioning error. U represents the specific accuracy of the positioning object. U is a numerical value between 0 and 1. For example, when analyzing an image of a specific person and the currently captured image and using their similarity to identify the person, this similarity can be used as U.

[0086] Next, use Figure 6 The operation of the in-building information management device 3 when storing the position information from the positioning device 31 will be described.

[0087] Figure 6 This is a flowchart for explaining the operation of the in-building information management device in Embodiment 1 when storing position information from the positioning device.

[0088] In step S1, the in-building information management device 3 determines whether it has received location information from the positioning device 31. If no location information has been received in step S1, the in-building information management device 3 proceeds to step S1. If location information has been received from the positioning device 31 in step S1, the location management device 21 proceeds to step S2.

[0089] In step S2, the in-building information management device 3 stores the position information from the positioning device 31. Then, the in-building information management device 3 performs the operation of step S3. In step S3, the in-building information management device 3 determines whether to stop receiving the position information from the positioning device 31.

[0090] If the reception of position information from the positioning device 31 does not need to be completed in step S3, the in-building information management device 3 performs the operation of step S1. If the reception of position information from the positioning device 31 does need to be completed in step S3, the in-building information management device 3 ends the operation.

[0091] Next, use Figure 7 The operation of the in-building information management device 3 when determining the position information of the positioning target will be described.

[0092] Figure 7 This is a flowchart for explaining the operation of the in-building information management device in the first embodiment when determining the position information of the positioning target.

[0093] In step S11, the building information management device 3 determines whether it is necessary to determine the location information of the location measurement target. If it is not necessary to determine the location information of the location measurement target in step S11, the building information management device 3 proceeds to step S11. If it is necessary to determine the location information of the location measurement target in step S11, the building information management device 3 proceeds to step S12.

[0094] In step S12, the building information management device 3 determines the usage information. Then, the building information management device 3 proceeds to step S13. In step S13, the building information management device 3 determines the order of the positioning targets used to determine the position information. Then, the building information management device 3 proceeds to step S14. In step S14, the building information management device 3 extracts the positioning targets used to determine the position information.

[0095] The building information management device 3 then proceeds to step S15. In step S15, the building information management device 3 determines the location and time of each location measurement target. The building information management device 3 then proceeds to step S16. In step S16, the building information management device 3 determines whether the location information of all locations measurement targets has been determined.

[0096] If the position information of any positioning target has not been determined in step S16, the in-building information management device 3 performs the operation of step S14. If the position information of all positioning targets has been determined in step S16, the position management device 21 performs the operation of step S17.

[0097] In step S17, the building information management device 3 determines whether to terminate the position determination of the target object. If the position determination of the target object does not need to be terminated in step S17, the building information management device 3 performs the operation of step S11. If the position determination of the target object needs to be terminated in step S17, the building information management device 3 terminates the operation.

[0098] According to the first embodiment described above, the in-building information management device 3 communicates with devices and stores their location information. This allows not only the acquisition of device location information but also the fulfillment of requests directed to the devices. As a result, application software 1 related to the devices can be easily constructed, enabling the rapid provision of various services.

[0099] Furthermore, the position information from the positioning device 31 and the position information of the measurement target are managed separately and maintain a relationship. Therefore, while maintaining scalability such as increasing or decreasing the positioning device 31, the position information of the measurement target can be appropriately determined based on the highly reliable position information.

[0100] Furthermore, the position information of the target to be positioned is determined based on the position information from the plurality of positioning devices 31. Therefore, the position information of the target to be positioned can be determined with higher accuracy.

[0101] Furthermore, the position information of a certain positioning target may affect the position information of other positioning targets. Therefore, by determining the position information of the positioning targets in a more appropriate order, more accurate position information can be determined.

[0102] Furthermore, if the position information of a particular measurement target affects the determination of the position information of other measurement targets, the position information of the measurement target for which more reliable position information is desired can be used for determination. In this case, the position information of both measurement targets can be determined more accurately. For example, the order of measurement targets for which more measurement devices 31 have their position information measured can be prioritized. For example, the order of measurement targets for which the measurement devices 31 have their position information measured closer to the time of position determination can be prioritized.

[0103] Furthermore, the influence on the position information of the positioning device 31 may be adjusted in the form of weighted average. In this case, the position information of the positioning device 31 can be determined more accurately.

[0104] In addition, according to the positioning device 31, specific variables are accurate. For example, the height (z) can be obtained by the air pressure sensor, acceleration sensor, etc. of the smartphone, but the height (z) information possessed by the elevator device 8 is more accurate. On the other hand, in the horizontal two axes (x, y) other than the height, positioning based on Lidar and PDR can be performed more detailed and accurately. Therefore, when determining the height (z), if the weight of the height measured by the elevator is increased, and the weight of the position information based on positioning other than the elevator is increased in the horizontal two axes (x, y), the position information of the positioning device 31 can be determined more accurately.

[0105] Furthermore, the weight coefficient of the weighted average is determined dynamically. Therefore, by adjusting the weight according to the situation, the position information of the positioning device 31 can be determined more accurately.

[0106] Furthermore, it is difficult to consider the situation where multiple positioning targets overlap. Therefore, after determining the position information of the positioning target, the influence of the position information overlapping with the positions of other positioning targets is reduced, thereby making it possible to more accurately determine the position information of the positioning device 31.

[0107] Furthermore, if the weight is determined so as to increase the influence of position information at a time close to the position information to be determined, the position information of the positioning device 31 can be determined more accurately.

[0108] Furthermore, by reducing the influence of position information that may be position information of other positioning targets, the position information of the positioning device 31 can be determined more accurately.

[0109] Furthermore, by correcting the position information of the positioning target using the map information, the position information of the positioning device 31 can be determined more accurately.

[0110] Furthermore, autonomous mobile devices are defined as mechanical devices that move autonomously even without human control, such as robots 16. Personal mobile devices are also a type of autonomous mobile device. Applying the in-building information management system 3 to autonomous mobile devices allows accurate determination of their positional information.

[0111] Next, use Figure 8 An example of the in-building information management device 3 will be described.

[0112] Figure 8 This is a hardware configuration diagram of the in-building information management device in the first embodiment.

[0113] Each function of the in-building information management device 3 can be realized by a processing circuit. For example, the processing circuit includes at least one processor 100a and at least one memory 100b. For example, the processing circuit includes at least one dedicated hardware 200.

[0114] When the processing circuit has at least one processor 100a and at least one memory 100b, the various functions of the in-building information management device 3 are implemented by software, firmware, or a combination of software and firmware. At least one of the software and firmware is referred to as a program. At least one of the software and firmware is stored in at least one memory 100b. The at least one processor 100a reads and executes the program stored in the at least one memory 100b, thereby implementing the various functions of the in-building information management device 3. The at least one processor 100a is also called a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. For example, the at least one memory 100b is a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM, a magnetic disk, a floppy disk, an optical disk, a high-density disk, a minidisc, or a DVD.

[0115] When the processing circuit comprises at least one dedicated hardware component 200, the processing circuit may be implemented, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the in-building information management device 3 may be implemented separately by the processing circuit. For example, each function of the in-building information management device 3 may be implemented collectively by the processing circuit.

[0116] The functions of the in-building information management device 3 may be partially implemented by dedicated hardware 200, and partially implemented by software or firmware. For example, the functions of the position determination unit 28 may be implemented by a processing circuit as dedicated hardware 200, while the functions other than the functions of the control unit 9b may be implemented by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0117] In this way, the processing circuit implements the various functions of the in-building information management device 3 through hardware 200, software, firmware, or a combination thereof.
