[0006] Problems to be solved by the invention

[0007] However, in the prior art, for the configuration position of wireless devices, the distance between wireless devices is estimated based on the radio wave strength of the wireless devices, and the configuration of the wireless devices is derived. However, when there are obstacles between wireless devices, the radio wave strength sometimes becomes weak. Therefore, it is sometimes impossible to accurately estimate the configuration of the wireless devices. The purpose of the present disclosure is to provide an estimation system and an estimation method that can accurately estimate the configuration of multiple objects.

[0008] Means for solving problems

[0009] An estimation system for solving this problem is an estimation system for estimating the configuration of an object, and includes an estimation unit, which obtains information related to the configuration pattern of the object as first information, obtains information including the response time between the wireless devices from a wireless device connected to the object as second information, and estimates the configuration of the object based on the first information and the second information. According to this structure, it is possible to estimate the combination of the object and the wireless device in the configuration pattern based on the information including the response time between the wireless devices and the information related to the configuration pattern of the object. As a result, the configuration of the object can be accurately estimated in a manner corresponding to the wireless device.

[0010] In the estimation system, the estimation unit estimates the combination of the objects and the wireless devices in the configuration pattern based on the first information and the second information in a configuration space where a plurality of the wireless devices and a plurality of objects are connected one-to-one, obtains inherent information of the objects connected to the wireless devices from the wireless devices, and establishes a correspondence between the inherent information of the objects and the objects in the configuration pattern based on the combination of the objects and the wireless devices in the configuration pattern and the inherent information of the objects. According to this structure, the configuration of the objects can be estimated in a manner that the inherent information of the objects is established in correspondence.

[0011] In the above-mentioned estimation system, there is also a specific wireless device that can communicate with the wireless device and is configured in the configuration space. The estimation unit defines the specific wireless device as belonging to any one of the object and the wireless device, obtains information related to the configuration pattern of multiple objects configured in the configuration space and the specific wireless device as the first information, obtains information including the response time between the wireless devices in the multiple wireless devices as the second information, and the information is obtained from a wireless device group having the wireless device and the specific wireless device. Based on the first information and the second information, the combination of the object and the wireless device in the configuration pattern is estimated.

[0012] Since the specific wireless device is an object and a wireless device, the specific wireless device can be treated as a combination of the object and the wireless device that is predetermined in the estimation of the combination of the object and the wireless device. By arranging such a specific wireless device at a predetermined position in the arrangement space, a state is achieved in which one group is determined among the groups consisting of the object including the specific wireless device and the wireless device including the specific wireless device, so that the estimation accuracy of the combination of other objects and other wireless devices can be improved.

[0013] In the estimation system, the estimation unit acquires starting point information that specifies a combination of the object and the wireless device, and estimates the combination of the object and the wireless device in the arrangement pattern based on the starting point information, the first information, and the second information.

[0014] According to this configuration, one of the groups consisting of the object and the wireless device is identified, so that the estimation accuracy of the combination of other objects and other wireless devices can be improved.

[0015] In the above-mentioned estimation system, the estimation unit calculates the difference between the number of the objects obtained based on the first information and the number of the wireless devices obtained based on the second information, and estimates the combination of the objects and the wireless devices in the configuration pattern when the difference does not exist.

[0016] When the configuration space is wide, sometimes it is impossible to obtain information from a part of the multiple wireless devices configured in the configuration space. On the other hand, there is also a situation where information is obtained from all the multiple wireless devices configured in the configuration space. When the number of objects configured in the configuration space is consistent with the number of wireless devices, it can be estimated that information is obtained from all the multiple wireless devices configured in the configuration space. According to this structure, when the number of objects configured in the configuration space is consistent with the number of wireless devices and there is no difference in quantity, the combination of objects and wireless devices is estimated. If the estimation is performed when there is a difference in quantity, the calculation will be invalid, but the estimation processing performed when there is such a difference in quantity can be suppressed.

[0017] In the above-mentioned estimation system, the estimation unit calculates the difference between the number of objects obtained from the first information and the number of wireless devices obtained based on the second information. When the difference exists, a specified space containing the same number of objects as the wireless devices is determined in the configuration space, and information related to the configuration pattern of multiple objects configured in the specified space is obtained from the first information as the first information. Based on the first information and the second information, the combination of the objects and the wireless devices in the configuration pattern is estimated.

[0018] According to this configuration, even when the number of objects and the number of wireless devices arranged in the arrangement space do not match and there is a number difference, the combination of the objects and the wireless devices can be estimated.

[0019] In the above estimation system, the estimation unit further obtains third information related to the object and fourth information related to the wireless device and associated with the third information, and the estimation unit estimates the combination of the object and the wireless device in the configuration pattern based on at least the first information, the second information, the third information, and the fourth information. According to this structure, information associated with the object and the wireless device is used in the estimation of the combination. As a result, the estimation accuracy of the combination between the object and the wireless device can be improved.

[0020] In the estimation system, the first information is any one of two-dimensional information including position information of the plurality of objects, three-dimensional information including position information of the plurality of objects, and a configuration diagram of the plurality of objects. According to this structure, the combination between the object and the wireless device can be estimated based on any one of the two-dimensional information, the three-dimensional information, and the configuration diagram.

[0021] In the estimation system, after estimating the combination of the object and the wireless device, the estimation unit stores the combination of the object and the wireless device in the configuration pattern in a storage device. According to this structure, after the combination of the object and the wireless device is stored, information related to the combination of the object and the wireless device can be obtained from the storage device.

[0022] In the above-mentioned estimation system, the estimation unit displays the combination of the object and the wireless device in the arrangement pattern on a display device.

[0023] According to this configuration, the combination of the object and the wireless device can be visually confirmed.

[0024] The estimation system further includes a determination unit that determines whether the combination of the object and the wireless device in the configuration pattern is correct or not, and the determination unit detects whether the object and the wireless device are linked by performing at least one action confirmation process on the object and the wireless device in a combined relationship with the object, namely, causing the object to move via the wireless device and causing the object to move to obtain information from the wireless device connected to the object, and if the wireless device and the object are linked, it is determined that the estimation of the combined relationship of the object and the wireless device in the configuration pattern is correct, and if the object and the wireless device are not linked in the configuration pattern, it is determined that the estimation of the combined relationship of the object and the wireless device is incorrect. According to this structure, it is possible to determine whether the combined relationship of the object and the wireless device is correct or not.

[0025] In the above estimation system, when it is determined that the estimation of the combination relationship between the object and the wireless device is correct, the combination relationship between the object and the wireless device in the configuration mode is correct, and when it is determined that the estimation of the combination relationship between the object and the wireless device is wrong, the combination relationship between the object and the wireless device in the configuration mode is wrong. According to this structure, it is possible to notify whether the combination relationship between the object and the wireless device is correct or not.

[0026] The inference method for solving this problem is an inference method for inferring the configuration of an object, obtaining information related to the configuration pattern of the object as first information, obtaining information including the response time between the wireless devices from the wireless devices connected to the object as second information, and inferring the configuration of the object based on the first information and the second information. According to this structure, the combination of the object and the wireless device in the configuration pattern can be inferred based on the information including the response time between the wireless devices and the information related to the configuration pattern of the object, thereby accurately inferring the configuration of the object.

[0042] <First embodiment>

[0043] Below, refer to Figures 1 to 8 , the estimation system involved in this embodiment is described.

[0044] If the wireless device 5 is connected to the object 4, the inherent information of the object 4 can be obtained from the wireless device 5. Sometimes it is unknown where the object 4 having the inherent information is arranged in the building. In addition, sometimes multiple objects 4 without inherent information are recorded in the equipment map. In this case, the configuration pattern of multiple objects 4 can be obtained from the equipment map. However, since the information of each object 4 is unknown, it is impossible to determine which object 4 in the equipment map the object 4 having the inherent information obtained from the wireless device 5 corresponds to. In this embodiment, the inference system 1 infers the configuration of the object 4 in a manner that knows the correspondence between the object 4 and the wireless device 5. Alternatively, the inference system 1 infers the configuration of the object 4 in a manner that knows the inherent information of the object 4.

[0045] Specifically, the estimation system 1 acquires the first information as information on the arrangement pattern of the objects 4. The estimation system 1 assigns identification numbers to the plurality of objects 4 in the arrangement pattern. The identification numbers are numbers for identifying the plurality of objects 4 in the arrangement pattern.

[0046] In the construction of the management system 2 for managing a plurality of objects 4, the wireless device 5 is connected to each of the plurality of objects 4 configured in the configuration space DS. At this time, a configuration space DS is formed in which the plurality of objects 4 are connected to the plurality of wireless devices 5 one-to-one. At this stage, the inference system 1 has not set the combination of the object 4 and the wireless device 5 in the configuration pattern. At this stage, the combination of the object 4 and the wireless device 5 in the configuration pattern is inferred. The inference system 1 derives the configuration of the object 4 corresponding to the wireless device 5 based on the combination of the object 4 and the wireless device 5 in the configuration pattern. Furthermore, the inference system 1 can obtain the inherent information of the object 4 connected to the wireless device 5 from the wireless device 5. In this case, based on the combination of the object 4 and the wireless device 5 in the configuration pattern and the inherent information of the object 4, the configuration of the object 4 corresponding to the inherent information is derived.

[0047] An example of a management system 2 is given below. The management system 2 includes a management unit 3 and wireless devices 5 connected to multiple objects 4 respectively. The wireless device 5 sends information related to the object 4 (hereinafter referred to as "object-related information") to the management unit 3. The object-related information includes inherent information of the object 4, information used by the object 4 for the control of the object 4 itself, information indicating the state of the object 4 itself, and information of objects involved in the object 4. The inherent information of the object 4 is information inherent to the object 4, and is information assigned to the object 4 when it leaves the factory or is produced. The management unit 3 obtains the object-related information from the wireless device 5 connected to the object 4. An example of the management unit 3 is a server. The management unit 3 manages the object-related information of each of the multiple objects 4.

[0048] In the construction operation of such a management system 2, as described above, there is an operation of connecting the wireless device 5 to the object 4. When connecting, the wireless device 5 is sometimes connected to the object 4 without obtaining a combination of the identification numbers of the object 4 and the wireless device 5 in the configuration pattern. In such a case, the object-related information of the object 4 can be obtained via the wireless device 5. However, as described above, in the configuration pattern shown in the device diagram, it is impossible to know which object 4 the object-related information of the object 4 is. In view of such a situation, it is necessary to accurately infer the configuration of the object 4 in the configuration pattern. If the configuration of the object 4 in the configuration pattern is determined, when the management unit 3 obtains the object-related information of the object 4 via the wireless device 5, it can associate the obtained information with the specified object 4 in the configuration pattern shown in the device diagram. As a result, the user of the management system 2 can understand the status of the object 4 in the configuration pattern based on the object-related information of the object 4.

[0049] As an example of object 4, electrical equipment can be cited. Electrical equipment includes devices that are operated by electricity, and devices that are operated by power other than electricity and are controlled by electricity. As electrical equipment, indoor units, outdoor units, fan units, total heat exchangers, cold water pumps, hot water pumps, electric valves installed in pipes, cooling devices, heating devices, surveillance cameras, and sensors of air conditioners can be cited. In the case where object 4 is an electrical device, information used by the electrical device in the control of the electrical device, information indicating the operating state of the electrical device, and information indicating abnormalities of the electrical device are respectively equivalent to object-related information. The electrical device is configured to output the object-related information to the wireless device 5.

[0050] When the object 4 is a sensor, the detection value detected by the sensor, the information indicating the operating state of the sensor, and the information indicating the abnormal state of the sensor correspond to the object-related information. The sensor is configured to output the object-related information to the wireless device 5. Examples of the sensor include an ammeter, a voltmeter, a weight sensor, a strain sensor, a torque sensor, a rotation angle sensor, a position sensor, an image sensor, a smoke sensor, a temperature sensor for the object 4, an illuminance sensor, a flow sensor, a human sensor, a thermometer, and a hygrometer. The sensor is configured to output the object-related information to the wireless device 5.

[0051] Reference Figure 1 , an example of the management system 2 is described. The management system 2 manages the indoor unit 8 of the air conditioner. The indoor unit 8 is equivalent to the object 4 managed by the management system 2. The management system 2 includes a management unit 3 and wireless devices 5 respectively connected to the plurality of indoor units 8. The management unit 3 obtains object-related information from the plurality of indoor units 8 via the wireless device 5. The management unit 3 manages the indoor unit 8 based on the object-related information.

[0052] The indoor unit 8 transmits the object-related information to the management unit 3 via the wireless device 5. The wireless device 5 has an identification number. The wireless device 5 includes a communication unit 7. The communication unit 7 transmits the object-related information together with the identification number to the management unit 3 via a connection device 9 connected to the network N. The connection device 9 is composed of, for example, a gateway or a router. The communication unit 7 communicates in accordance with a prescribed communication standard. Examples of the prescribed communication standard include a standard based on IMT-2000, a standard based on IMT-Advanced, and a fifth generation standard. The network N includes at least one of the Internet, a local area network, a mobile phone communication network, and a dedicated line network.

[0053] The wireless device 5 includes a response time measurement unit 6. The response time measurement unit 6 measures the response time in the communication between the two wireless devices 5. The response time measurement unit 6 stores the response time between the wireless devices 5 as information (hereinafter referred to as "response time information"). The response time is defined as the time until a predetermined signal output from the wireless device 5 on the transmitting side reaches the wireless device 5 on the receiving side and returns to the wireless device 5 on the transmitting side in the communication between the two wireless devices 5. Specifically, the response time is defined as the sum of the outbound time until the predetermined signal output from the wireless device 5 on the transmitting side reaches the wireless device 5 on the receiving side and the return time until the predetermined signal output from the wireless device 5 on the receiving side reaches the wireless device 5 on the transmitting side. Here, as the signal, there can be cited radio wave signals, sound wave signals, and optical signals.

[0054] The wireless device 5 transmits the response time information to the estimation unit 10 of the estimation system 1 via the communication unit 7. When transmitting the response time information, the wireless device 5 transmits the identification numbers of the two wireless devices 5 related to the response time included in the response time information together with the response time information. Furthermore, the wireless device 5 transmits the identification number of the wireless device 5 and the inherent information of the object 4 connected to the wireless device 5 as a set to the estimation unit 10 of the estimation system 1. The estimation unit 10 stores the identification number of the wireless device 5 and the inherent information of the object 4 connected to the wireless device 5 as a set of data.

[0055] Reference Figure 2 and Figure 3 , the estimation system 1 is described. The estimation system 1 has an estimation unit 10. The estimation unit 10 is composed of an operation circuit. The operation circuit is composed of a CPU (Central Processing Unit) or an MPU (Micro-processing unit). Specifically, the operation circuit can be configured to include 1) one or more processors that perform various processes according to a computer program (software), 2) one or more dedicated hardware circuits such as an integrated circuit (ASIC) for a specific purpose that performs at least part of the various processes, or 3) a combination of circuits (circuitry) thereof. The processor includes a CPU or an MPU and a memory such as a RAM and a ROM, and the memory stores a program code or instruction configured to enable the CPU to perform a process. The memory, i.e., a computer-readable medium, includes all available media that can be accessed by a general-purpose or special-purpose computer.

[0056] The estimation unit 10 obtains first information and second information. The estimation unit 10 estimates the configuration of the object 4 based on the first information and the second information. The first information is information related to the configuration pattern of multiple objects 4 configured in the configuration space DS. The configuration pattern is information indicating the positional relationship of multiple objects 4 whose objects 4 are not identified. In the present embodiment, the configuration pattern of the object 4 is information different from the configuration of the object 4. The configuration of the object 4 indicates the configuration pattern of the object 4 that determines the object 4 in a manner that makes it known to which object the object-related information obtained via the wireless device 5 belongs. Specifically, the configuration of the object 4 indicates the configuration pattern of the object 4 whose inherent information of the object 4 is clear. Alternatively, the configuration of the object 4 indicates the configuration pattern of the object 4 whose connection relationship with the wireless device 5 whose identification number has been determined is clear.

[0057] The first information may be any information that can read the inter-object distance or inter-object distance ratio of the plurality of objects 4 arranged in the arrangement space DS. The estimation unit 10 reads the inter-object distance or inter-object distance ratio of the plurality of objects from the first information. In the following description, the inter-object distance includes the inter-object distance ratio.

[0058] Specifically, as the first information, there can be cited two-dimensional information including position information of the plurality of objects 4, three-dimensional information including position information of the plurality of objects 4, and a layout diagram of the plurality of objects 4 (see Figure 3 ). As two-dimensional information, two-dimensional CAD data, design drawings recorded on paper, and image data captured by a camera can be cited. As three-dimensional information, three-dimensional CAD data can be cited. The first information does not include inherent information of the object 4.

[0059] The estimation unit 10 obtains the first information and assigns identification numbers to the objects 4 in the configuration pattern. The estimation unit 10 assigns identification numbers to the objects 4 by any method. The identification number may be a number consisting of a number or a number consisting of characters. The identification number is a number used to identify a plurality of objects 4 in the configuration pattern. When the estimation unit 10 obtains the inter-object distance based on the first information, it obtains the identification numbers of the two objects 4 related to the inter-object distance. The estimation unit 10 stores the identification numbers of the two objects 4 and the inter-object distance between the two objects 4 as a set of data.

[0060] The estimating unit 10 calculates the inter-object distance based on at least one of two-dimensional information including position information of the plurality of objects 4 , three-dimensional information including position information of the plurality of objects 4 , and an arrangement diagram of the plurality of objects 4 .

[0061] The distance between objects may be a value corresponding to the actual distance or a standardized value. In one example of standardization, the distances between objects are adjusted so that the largest value among the distances between objects becomes a specified value (e.g., "1"). For example, when "10", "50", and "100" are assigned as the distances between objects, after standardization, these distances between objects become "0.1", "0.5", and "1".

[0062] The second information is information including the response time between the wireless devices 5 (hereinafter referred to as "response time information"). The estimation unit 10 obtains the response time information from the wireless device 5 via the connection device 9. When the response time information is stored in the server that connects the wireless device 5 to the Internet, the estimation unit 10 obtains the response time information from the server. When obtaining the response time information, the estimation unit 10 obtains the identification numbers of the two wireless devices 5 related to the response time information from the management unit 3 or the wireless device 5. Furthermore, the estimation unit 10 obtains the inherent information of the object 4 connected to the wireless device 5 from the wireless device 5. The estimation unit 10 stores the identification numbers of the two wireless devices 5 and the response time information between the two wireless devices 5 as a set of data. In addition, the estimation unit 10 stores the identification numbers of the wireless devices 5 and the inherent information of the object 4 connected to the wireless device 5 as a set of data.

[0063] The response time may be normalized. For example, when "0.001 seconds", "0.005 seconds", and "0.01 seconds" are assigned as the response time, the normalized response time is "0.1", "0.5", and "1".

[0064] Next, the estimation of the combination of the object 4 and the wireless device 5 in the arrangement pattern will be described.

[0065] The estimation unit 10 defines a permutation selected from the first set having the distance between objects as an element as a first permutation. In one example, the estimation unit 10 randomly selects one element from the first set having the distance between objects as an element to create the first permutation. The first permutation is a permutation in which the distance between objects, which are elements of the first set, are arranged.

[0066] In one example, the estimation unit 10 creates a first arrangement as follows. The estimation unit 10 selects one object 4 from a plurality of objects 4 through a selection process. The selection method of the selection process is not limited. For example, in the selection process of the estimation unit 10, one object 4 is selected from a plurality of objects 4 randomly or according to a predetermined rule. Next, the estimation unit 10 forms a first arrangement from a first set of elements of distances between objects, taking the selected object 4 as a starting point. Specifically, the objects 4 are arranged in order from near to far from the object 4 serving as the starting point. The first arrangement is constituted by arranging the distances of two objects 4 that are sequentially combined from the starting point among the objects 4 arranged in sequence. For example, in the case where the object 4 is arranged with the object 4 (A), the object 4 (B), and the object 4 (C), the first arrangement is formed by arranging the distance between the object 4 (A) and the object 4 (B), the distance between the object 4 (A) and the object 4 (C), and the distance between the object 4 (B) and the object 4 (C) in sequence.

[0067] exist Figure 3In the example shown, the inter-object distance between object 4(A) and object 4(B) is x1, the inter-object distance between object 4(A) and object 4(C) is x2, and the inter-object distance between object 4(B) and object 4(C) is x3. In this case, the first set with inter-object distance as an element includes x1, x2, and x3. The estimation unit 10 selects any one of object 4(A) to object 4(C) as the starting point. In the case where the estimation unit 10 selects object 4(A) as the starting point, the plurality of objects 4 are arranged in order from near to far from the object 4(A) as the starting point. The estimation unit 10 arranges the inter-object distances based on the order of the arrangement. For example, in the case where object 4(B) is closer to object 4(A) as the starting point than object 4(C), the estimation unit 10 arranges the plurality of objects 4 in the order of object 4(A), object 4(B), and object 4(C). Furthermore, the estimation unit 10 arranges the inter-object distances in the order of the inter-object distance x1, the inter-object distance x2, and the inter-object distance x3, and defines the arrangement [x1, x2, x3] of the arrangement as a first arrangement. The estimation unit 10 processes the inter-object distances, which are elements of the first arrangement, and the identification numbers of the two objects 4 related to the inter-object distances as one group. In this example, the estimation unit 10 processes x1, A, and B as one group, x2, A, and C as one group, and x3, B, and C as one group. Figure 4 4 is a diagram showing the relationship between the identification number of the object 4 and the distance between the objects. Figure 4 In the figure, the number on the upper right of each grid indicates the rank of the element in the arrangement.

[0068] The estimation unit 10 defines a group of permutations that can be selected from the second set with response time as an element as a first permutation group. When the number of elements included in the second set with response time as an element is set to n, the first permutation group is a group of permutations (also referred to as permutations) obtained by selecting n elements from n elements. In this embodiment, the second set with response time as an element includes y1, y2, and y3. Figure 3 In the case of the combination of the object 4 and the wireless device 5 in the undetermined configuration mode, Figure 3 y1, y2, and y3 are not recorded.

[0069] In this embodiment, the response time between wireless device 5(a) and wireless device 5(b) is y1, the response time between wireless device 5(a) and wireless device 5(c) is y2, and the response time between wireless device 5(c) and wireless device 5(b) is y3. Figure 5As shown, when the three elements of response time are y1, y2, and y3, the number of permutations of the elements of the first permutation group is 6, namely, [y1, y2, y3], [y1, y3, y2], [y2, y1, y3], [y2, y3, y1], [y3, y1, y2], [y3, y2, y1].

[0070] The estimation unit 10 treats the response time as an element of the array and the identification numbers of the two wireless devices 5 associated with the response time as one group. In this example, y1, a and b are one group, y2, c and a are one group, and y3, b and c are one group. Figure 6 This is a diagram showing the relationship between the identification number of the wireless device 5 and the response time. Figure 6 is a diagram showing the relationship between the identification number of the wireless device 5 and the response time. Figure 6 In the figure, the number on the upper right of each grid indicates the rank of the element in the arrangement.

[0071] The estimation unit 10 determines the arrangement closest to the first arrangement from the first arrangement group as a similar arrangement (refer to Figure 7 as well as Figure 8 ). Specifically, the estimation unit 10 selects one from each of the first permutation group, compares the selected permutation with the first permutation, and finds the permutation closest to the first permutation from the first permutation group.

[0072] The closeness of two arrays is defined as the sum of the differences between the elements of one array and the elements of the other array. The "difference" is a value related to the difference between two values, and takes a positive value. The "difference" can be the absolute value of the difference, the value obtained by raising the difference to the square, or the value obtained by raising the difference to the fourth power. The closest two arrays means that the sum of the "differences" is the smallest.

[0073] “Two arrangements are closest” may mean being substantially the smallest. In this case, if there is an arrangement with the smallest sum of “differences” and an arrangement with a value slightly larger than the smallest sum of “differences”, both are substantially the smallest arrangements.

[0074] In this embodiment, in the first arrangement group, the arrangement closest to the first arrangement is called a similar arrangement. In the first arrangement group, there may be one arrangement closest to the first arrangement or there may be multiple arrangements.

[0075] The estimating unit 10 estimates the combination of the object 4 and the wireless device 5 based on the comparison between the first arrangement and the similar arrangement.

[0076] In this embodiment, the estimation unit 10 establishes a correspondence between the first-ranked element of the first arrangement and the first-ranked element of the similar arrangement. The estimation unit 10 establishes a correspondence between the second-ranked element of the first arrangement and the second-ranked element of the similar arrangement. The estimation unit 10 establishes a correspondence between the third-ranked element of the first arrangement and the third-ranked element of the similar arrangement.

[0077] Based on the correspondence, the estimating unit 10 associates the identification numbers of the two objects 4 associated with the first-order elements of the first array with the identification numbers of the two wireless devices 5 associated with the first-order elements of the similar array (see Figure 8 ). By the same method, the inference unit 10 establishes a correspondence between the identification numbers of the two objects 4 corresponding to the second-ranked elements of the first arrangement and the identification numbers of the two wireless devices 5 corresponding to the second-ranked elements of the similar arrangement based on the correspondence between the second-ranked elements of the first arrangement and the second-ranked elements of the similar arrangement (refer to Figure 8 Similarly, the estimating unit 10 establishes correspondence between all elements of the first arrangement and elements of the similar arrangement.

[0078] The estimation unit 10 determines the corresponding relationship between the identification numbers of the two objects 4 and the identification numbers of the two wireless devices 5 (“the corresponding relationship between the two objects 4 and the two wireless devices 5”, see Figure 8 ), for each of the identification numbers of the plurality of objects 4, the identification numbers of the wireless devices 5 corresponding to the identification numbers of the objects 4 are derived (refer to Figure 8 The identification number is a number assigned to the object 4 shown in the configuration pattern, so the combination of the object 4 and the wireless device 5 in the configuration pattern is determined by deriving the identification number of the wireless device 5 combined with the identification number of the object 4.

[0079] After estimating the combination of the object 4 and the wireless device 5 in the configuration pattern, the estimation unit 10 refers to a set of data of the identification number of the wireless device 5 and the inherent information of the object 4 connected to the wireless device 5. Then, the estimation unit 10 stores the identification number of the object 4 in the configuration pattern and the inherent information of the object 4 as a set of data. In this way, the inherent information of the object 4 is associated with the object 4 in the configuration pattern. As described above, the configuration of the object 4 that is associated with the inherent information of the object 4 is estimated.

[0080] Preferably, after estimating the combination of the object 4 and the wireless device 5 in the configuration pattern, the estimating unit 10 stores the combination of the object 4 and the wireless device 5 in the configuration pattern in the storage device 11. Alternatively, preferably, after estimating the combination of the object 4 and the wireless device 5 in the configuration pattern, the estimating unit 10 stores the combination of the identification number and the inherent information of the object 4 in the configuration pattern in the storage device 11. The storage device 11 is composed of at least one of a volatile memory, a non-volatile memory, a hard disk, an optical disk, a magnetic disk, and a magnetic tape.

[0081] Preferably, the estimation unit 10 displays the combination of the object 4 and the wireless device 5 on the display device 14. Alternatively, preferably, the estimation unit 10 displays the combination of the object 4 in the configuration pattern and the inherent information of the object 4 on the display device 14. The display device 14 is composed of at least one of a liquid crystal monitor, a plasma display, an organic EL display, a projector, and VR glasses.

[0082] Specifically, the display device 14 displays the identification number of the object 4 near the object 4 in the configuration diagram of the object 4, and displays the identification number of the wireless device 5 combined with the object 4 and the inherent information of the object 4 near the object 4. At this time, the display device 14 can display the object 4 and the wireless device 5 as icons.

[0083] In order to clearly show the relationship between the object 4 and the inherent information of the object 4, the display device 14 may display the object 4 and the inherent information of the object 4 in a manner of connecting the object 4 with a line, or may display the object 4 and the inherent information of the object 4 in a manner of surrounding the object 4. In another example, the display device 14 displays a correspondence table between the identification number of the object 4 and the inherent information of the object 4 in the configuration mode, in which the identification number of the object 4 and the inherent information of the object 4 are arranged horizontally.

[0084] In order to clearly show the relationship between the object 4 and the wireless device 5 combined with the object 4, the display device 14 may display the object 4 and the wireless device 5 combined with the object 4 in a manner of connecting the object 4 and the wireless device 5 combined with the object 4 with a line, or may display the object 4 and the wireless device 5 combined with the object 4 in a manner of surrounding the object 4 and the wireless device 5 combined with the object 4. In another example, the display device 14 displays a correspondence table of the object 4 and the wireless device 5 in which the identification number of the object 4 and the identification number of the wireless device 5 combined with the object 4 are displayed in a horizontal arrangement.

[0085] like Figure 2 As shown, it is preferable that the estimation system 1 further includes a determination unit 12 that determines whether the combination of the object 4 and the wireless device 5 in the arrangement pattern is correct.

[0086] The determination unit 12 detects whether the object 4 and the wireless device 5 are linked by performing an action confirmation process. The first example of the action confirmation process is a process of causing the object 4 to move via the wireless device 5, with respect to the object 4 and the wireless device 5 in a combined relationship with the object 4. The second example of the action confirmation process is a process of causing the object 4 to move and obtaining information from the wireless device 5 connected to the object 4. The action confirmation process may also perform the process of the first example and the process of the second example.

[0087] For example, when determining the combination relationship between the object 4 in the configuration pattern and the wireless device 5 corresponding to the object 4 in the configuration pattern, the determination unit 12 issues an object confirmation command to the object 4 corresponding to the wireless device 5 via the wireless device 5. The object confirmation command is a test signal for confirming the response of the object 4. The determination unit 12 also instructs the wireless device 5 to output the object-related information to the determination unit 12 when the wireless device 5 receives the object-related information based on the object confirmation command from the object 4. When the determination unit 12 obtains the object-related information output from the object 4 from the wireless device 5 according to the object confirmation command, it determines that the wireless device 5 and the object 4 are linked. When the wireless device 5 and the object 4 are linked, the determination unit 12 determines that the estimation of the combination relationship between the object 4 and the wireless device 5 in the configuration pattern is correct. On the other hand, when the determination unit 12 does not obtain the object-related information output from the object 4 from the wireless device 5 according to the object confirmation command, it determines that the wireless device 5 and the object 4 are not linked. When the object 4 and the wireless device 5 are not linked, the determination unit 12 determines that the estimation of the combination relationship between the object 4 and the wireless device 5 in the configuration pattern is wrong.

[0088] like Figure 2 As shown in FIG. 1 , the estimation system 1 preferably further includes a notification unit 13 for notifying the result of the determination unit 12 .

[0089] When the notification unit 13 determines that the estimated combination relationship of the object 4 and the wireless device 5 in the configuration pattern is correct, the notification unit 13 notifies that the combination relationship of the object 4 and the wireless device 5 in the configuration pattern is correct. When the notification unit 13 determines that the estimated combination relationship of the object 4 and the wireless device 5 in the configuration pattern is wrong, the notification unit 13 notifies that the combination relationship of the object 4 and the wireless device 5 in the configuration pattern is wrong.

[0090] For example, the notification unit 13 displays the estimated correctness result of the combination relationship between the object 4 and the wireless device 5 in the configuration pattern on the display device 14. Alternatively, the notification unit 13 may output the estimated correctness result of the combination relationship between the object 4 and the wireless device 5 in the configuration pattern as sound through a speaker.

[0091] Reference Figure 3 to Figure 8 , an example of estimating the configuration of the object 4 in the configuration mode is described.

[0092] like Figure 3 As shown, the management system 2 to be estimated includes objects 4 and wireless devices 5 connected to the objects 4. In this example, the management system 2 includes three objects 4. The objects 4 are indoor units 8 of air conditioners. The objects 4 are connected to the wireless devices 5. The wireless devices 5 can communicate with each other. The wireless device 5 obtains the response time of the communication through communication with the communication partner, and obtains the response time as response time information. The wireless device 5 is configured to be able to send the response time information together with the identification numbers of the two wireless devices 5 to the estimation unit 10 of the estimation system 1 through the connection device 9. In addition, the wireless device 5 is configured to be able to access the object 4 connected to the wireless device 5 to obtain the inherent information of the object 4, and send the inherent information of the object 4 to the estimation unit 10 of the estimation system 1 through the connection device 9. An example of a period when the estimation system 1 is used for the management system 2 is when the wireless device 5 is connected to the object 4 but the combination of the object 4 and the wireless device 5 is not determined. Even when the combination of the object 4 and the wireless device 5 in the configuration pattern is determined, the estimation system 1 may be used for the management system 2 to confirm the combination of the object 4 and the wireless device 5 in the configuration pattern.

[0093] In the arrangement pattern, the estimating unit 10 assigns identification numbers "A", "B", and "C" to the three objects 4 (the three indoor units 8 in this example).

[0094] The estimation unit 10 uses the layout diagram of the building (refer to Figure 3 ) reads the inter-object distances of three objects 4. For example, the inference unit 10 calculates the inter-object distances of the three objects 4 based on the coordinates of the center of the object 4. In this example, the inter-object distance between object 4 (A) and object 4 (B) is "x1", the inter-object distance between object 4 (A) and object 4 (C) is "x2", and the inter-object distance between object 4 (B) and object 4 (C) is "x3". The inference unit 10 stores each inter-object distance in correspondence with the identification numbers of the two objects 4 related to the inter-object distance. Specifically, the inference unit 10 sets "x1" and "A, B" as a group, sets "x2" and "A, C" as a group, and sets "x3" and "B, C" as a group for storage.

[0095] The estimating unit 10 defines one array selected from the first set having the inter-object distance as an element as a first array.

[0096] In this example, the elements of the first set are "x1", "x2", and "x3". The estimation unit 10 selects one object 4 (A) from the plurality of objects 4 through selection processing. Next, the estimation unit 10 arranges the plurality of objects 4 in order of distance from the object 4 (A) as the starting point from the selected object 4 to the farthest point, thereby forming a first arrangement. In this example, the estimation unit 10 defines [x1, x2, x3] as the first arrangement. Figure 4 1 is a diagram showing the relationship between the inter-object distance, which is an element of the first array, and the identification number of the object 4 .

[0097] The estimation unit 10 acquires the response time information and the identification numbers of the two wireless devices 5 associated with the response time information from the wireless device 5 .

[0098] In this example, the identification numbers of the three wireless devices 5 are "a", "b", and "c". The response time between the wireless device 5(a) and the wireless device 5(b) is "y1", the response time between the wireless device 5(a) and the wireless device 5(c) is "y2", and the response time between the wireless device 5(b) and the wireless device 5(c) is "y3". The estimation unit 10 stores the response times in correspondence with the identification numbers of the two wireless devices 5 associated with the response times. Specifically, the estimation unit 10 stores "y1" and "a, b" as a group, "y2" and "a, c" as a group, and "y3" and "b, c" as a group.

[0099] Furthermore, the estimation unit 10 acquires the unique information of the object 4 connected to the wireless device 5 from the wireless device 5. The estimation unit 10 stores the identification number of the wireless device 5 and the unique information of the object 4 connected to the wireless device 5 as a set of data.

[0100] The estimation unit 10 defines a group of permutations selectable from the second set using response time as an element as a first permutation group. In this example, the elements of the second set are "y1", "y2", and "y3", and the number of elements included in the second set is "3".

[0101] like Figure 5 As shown, the estimation unit 10 creates all permutations that can be selected from the second set including y1 to y3. Six permutations R1 to R6 are created from the second set. Figure 6 This is a diagram showing the relationship between the response time, which is an element of the array R1, and the identification number of the wireless device 5.

[0102] like Figure 7 as well as Figure 8 As shown, the estimating unit 10 determines the arrangement closest to the first arrangement from the first arrangement group as a similar arrangement.

[0103] In this example, the estimation unit 10 calculates the proximity between the two arrays as a proximity index SM, which is defined as the sum of the squares of the differences between the elements of the first array related to the distance between objects and the elements of the array related to the response time in the same order.

[0104] The estimation unit 10 compares the first array related to the distance between objects with the arrays included in the first array group related to the response time, and calculates a similarity index SM for each array. The estimation unit 10 determines the array having the smallest value among the plurality of similarity indexes SM in the first array group as a similar array.

[0105] Figure 8 : is a diagram showing a first array related to distances between objects, a similar array related to response times closest to the first array, a proximity index SM derived from the two arrays, a correspondence between identification numbers of two objects 4 and identification numbers of two wireless devices 5, and a combination of objects 4 and wireless devices 5. In this example, the similar array related to response times closest to the first array is Figure 5 The arrangement R3[y2, y1, y3]. Figure 8 In the example, the elements of the similar arrangement [y2, y1, y3] are arranged so that the arrangement of the elements from the first rank to the third rank of the similar arrangement ( Figure 8 The configuration in the table of ) and the configuration from the first element to the third element in the first arrangement ( Figure 8 The configuration in the table is equal.

[0106] The estimating unit 10 estimates the combination of the object 4 and the wireless device 5 based on the comparison between the first arrangement and the similar arrangement.

[0107] Specifically, the estimation unit 10 establishes a correspondence between the first-ranked element of the first sequence and the first-ranked element of the similar sequence. The estimation unit 10 establishes a correspondence between the second-ranked element of the first sequence and the second-ranked element of the similar sequence. The estimation unit 10 establishes a correspondence between the third-ranked element of the first sequence and the third-ranked element of the similar sequence.

[0108] Based on the correspondence, the estimation unit 10 establishes a correspondence between the identification numbers of the two objects 4 corresponding to the first-ranked element of the first array and the identification numbers of the two wireless devices 5 corresponding to the first-ranked element of the similar array. The estimation unit 10 establishes a correspondence between the identification numbers of the two objects 4 corresponding to the second-ranked element of the first array and the identification numbers of the two wireless devices 5 corresponding to the second-ranked element of the similar array. The estimation unit 10 establishes a correspondence between the identification numbers of the two objects 4 corresponding to the third-ranked element of the first array and the identification numbers of the two wireless devices 5 corresponding to the third-ranked element of the similar array.

[0109] The estimation unit 10 determines the corresponding relationship between the identification numbers of the two objects 4 and the identification numbers of the two wireless devices 5 (“the corresponding relationship between the two objects 4 and the two wireless devices 5”, see Figure 8 ), for each of the identification numbers of the plurality of objects 4, the identification numbers of the wireless devices 5 corresponding to the identification numbers of the objects 4 are derived (refer to Figure 8 of objects and wireless devices).

[0110] Reference Figure 8 A specific example will be described. Figure 8 In the example of "the correspondence between two objects and two wireless devices", the identification numbers "A" and "B" of object 4 are corresponded to the identification numbers "a" and "c" of wireless device 5, and the identification numbers "B" and "C" of object 4 are corresponded to the identification numbers "c" and "b" of wireless device 5. In this case, both the former correspondence and the latter correspondence include "B" and "c". Thus, the inference unit 10 infers that "B" and "c" are in a corresponding relationship. Based on this inference, the inference unit 10 infers that "A" and "a" are in a corresponding relationship according to the former correspondence. Furthermore, the inference unit 10 infers that "C" and "b" are in a corresponding relationship according to the latter correspondence. This relationship is similar to the correspondence between the identification numbers "C" and "A" of object 4 and the identification numbers "b" and "c" of wireless device 5 as the third correspondence ( Figure 8 The third column of “the correspondence between two objects 4 and two wireless devices 5” matches.

[0111] The operation of this embodiment will be described.

[0112] As a method for estimating the combination of multiple objects 4 and multiple wireless devices 5 in the configuration pattern, for example, there is a method in which a command to move the object 4 is issued to one of the multiple wireless devices 5, and the moving object 4 is found based on the command, thereby determining the combination of the wireless device 5 and the object 4. However, in such a case, when multiple objects 4 are dispersedly arranged in a wide place, it is not easy to find the moving object 4 based on the command, and it takes time. In addition, when the number of objects 4 corresponding to the wireless device 5 is large, it is very troublesome.

[0113] In this regard, in the present embodiment, the estimation unit 10 estimates the combination of the plurality of objects 4 and the plurality of wireless devices 5 based on the relationship between the distances between the plurality of objects 4 and the relationship between the response times of the plurality of wireless devices 5. Therefore, the time for establishing the correspondence can be shortened compared to the case where the relationship between the combination of the objects 4 and the wireless devices 5 is acquired separately. In addition, since the response time is proportional to the distance between the wireless devices 5, according to the estimation system 1, the combination of the plurality of objects 4 and the plurality of wireless devices 5 in the configuration pattern can be accurately estimated. Thus, the configuration of the objects 4 can be accurately estimated in such a manner that the objects 4 in the configuration pattern are associated with the wireless devices 5. In addition, the estimation unit 10 associates the objects 4 in the configuration pattern with the inherent information of the objects 4 based on the information on the combination of the objects 4 and the wireless devices 5 in the configuration pattern and the information indicating the set of the identification number of the wireless device 5 and the inherent information of the objects 4 connected to the wireless device 5. Thus, the configuration of the objects 4 can be estimated in such a manner that the inherent information of the objects 4 is associated.

[0114] The effects of this embodiment will be described.

[0115] (1) The estimation system 1 includes an estimation unit 10 that estimates the configuration of the object 4 based on the first information and the second information. According to this structure, the combination of the object 4 and the wireless device 5 in the configuration pattern can be estimated based on the information including the response time between the wireless devices 5 and the information related to the configuration pattern of the object 4. As a result, the configuration of the object 4 can be accurately estimated in a manner corresponding to the wireless device 5.

[0116] (2) The estimating unit 10 estimates the combination of the object 4 and the wireless device 5 in the configuration pattern based on the first information and the second information. The estimating unit 10 obtains the inherent information of the object 4 connected to the wireless device 5 from the wireless device 5, and establishes a correspondence between the inherent information of the object 4 and the object 4 in the configuration pattern based on the combination of the object 4 and the wireless device 5 in the configuration pattern and the inherent information of the object 4. According to this structure, the configuration of the object 4 can be estimated in a manner that the configuration is associated with the inherent information of the object 4.

[0117] (3) The estimating unit 10 determines the arrangement closest to the first arrangement from the first arrangement group as a similar arrangement, and estimates the combination of the object 4 and the wireless device 5 based on the comparison between the first arrangement and the similar arrangement. According to this configuration, by repeating a simple procedure, the arrangement closest to the first arrangement can be determined from the first arrangement group, and based on this determination, the combination of multiple objects 4 and multiple wireless devices 5 can be estimated.

[0118] (4) The first information used in the estimation unit 10 is any one of two-dimensional information including position information of the plurality of objects 4, three-dimensional information including position information of the plurality of objects 4, and a configuration diagram of the plurality of objects 4. According to this configuration, the combination between the object 4 and the wireless device 5 can be estimated based on any one of the two-dimensional information, the three-dimensional information, and the configuration diagram.

[0119] (5) After estimating the combination of the object 4 and the wireless device 5, the estimating unit 10 stores the combination of the object 4 and the wireless device 5 in the configuration pattern in the storage device 11. According to this configuration, after the combination of the object 4 and the wireless device 5 is stored in the storage device 11, information related to the combination of the object 4 and the wireless device 5 can be obtained from the storage device 11.

[0120] (6) In the estimation system 1, the estimation unit 10 displays the combination of the object 4 and the wireless device 5 in the configuration pattern on the display device 14. According to this structure, the combination of the object 4 and the wireless device 5 can be visually confirmed. For example, from the screen showing the combination of the object 4 and the wireless device 5, the operator can easily identify the wireless device 5 corresponding to the object 4 located at a predetermined position in the configuration space DS. In addition, for a predetermined wireless device 5, the operator can identify the place where the object 4 corresponding to the wireless device 5 is arranged.

[0121] (7) The estimation system 1 further includes a determination unit 12 that determines whether the combination of the object 4 and the wireless device 5 in the configuration mode is correct. The determination unit 12 detects whether the object 4 and the wireless device 5 are linked by performing at least one of a first action confirmation process and a second action confirmation process. The first action confirmation process is a process of causing the object 4 to move via the wireless device 5 with respect to the object 4 and the wireless device 5 that is in a combined relationship with the object 4. The second action confirmation process is a process of causing the object 4 to move and obtain information from the wireless device 5 connected to the object 4. When the wireless device 5 and the object 4 are linked, the determination unit 12 determines that the estimation of the combined relationship of the object 4 and the wireless device 5 in the configuration mode is correct. When the object 4 and the wireless device 5 are not linked, the determination unit 12 determines that the estimation of the combined relationship of the object 4 and the wireless device 5 in the configuration mode is incorrect. According to this structure, the correctness of the combined relationship of the object 4 and the wireless device 5 can be determined.

[0122] (8) The estimation system 1 may include a notification unit 13. When the determination unit 12 determines that the estimation of the combination relationship between the object 4 and the wireless device 5 is correct, the notification unit 13 notifies that the combination relationship between the object 4 and the wireless device 5 in the configuration pattern is correct. When the determination unit 12 determines that the estimation of the combination relationship between the object 4 and the wireless device 5 is wrong, the notification unit 13 notifies that the combination relationship between the object 4 and the wireless device 5 in the configuration pattern is wrong. According to this structure, it is possible to notify whether the combination relationship between the object 4 and the wireless device 5 is correct or not.

[0123] (9) In the estimation method of the present embodiment, the estimation unit 10 obtains information related to the configuration pattern of the object 4 as the first information, and obtains information including the response time between the wireless devices 5 from the wireless device 5 connected to the object 4 as the second information. The estimation unit 10 estimates the configuration of the object 4 based on the first information and the second information. According to this structure, the combination of the object 4 and the wireless device 5 in the configuration pattern can be estimated based on the information including the response time between the wireless devices 5 and the information related to the configuration pattern of the object 4. As a result, the configuration of the object 4 can be accurately estimated in a manner corresponding to the wireless device 5.

[0124] <Second embodiment>

[0125] Reference Fig. 9 as well as Fig.10 , the estimation system 1 of the second embodiment is described. The estimation system 1 of this embodiment is different from the estimation system 1 of the first embodiment in that one arrangement is selected from the second set with response time as an element. In the following description, the same figure marks are marked on the common components with the estimation system 1 of the first embodiment, and their descriptions are omitted. In addition, the definition of the elements "x1", "x2", and "x3" of the first set and the definition of the elements "y1", "y2", and "y3" of the second set are the same as those of the first embodiment.

[0126] The estimation unit 10 defines one permutation selected from the second set with the response time as an element as a second permutation. In one example, the estimation unit 10 randomly selects one element each from the second set with the response time as an element to create the second permutation. The second permutation is a permutation in which the response time as an element of the second set is permuted. The estimation unit 10 treats the response time as an element of the second permutation and the identification numbers of the two wireless devices 5 related to the response time as one group.

[0127] In one example, the estimation unit 10 creates a second arrangement as follows. The estimation unit 10 selects one wireless device 5 from a plurality of wireless devices 5 through a selection process. The selection method of the selection process is not limited. For example, in the selection process of the estimation unit 10, one wireless device 5 is selected from a plurality of wireless devices 5 randomly or according to a predetermined rule. Next, the estimation unit 10 forms a second arrangement from a second set having response time as an element, taking the selected wireless device 5 as a starting point. Specifically, the wireless devices 5 are arranged in an ascending order of response time or an ascending order of response time, starting from the wireless device 5 serving as the starting point. The second arrangement is configured to arrange the response time between two wireless devices 5 that are sequentially combined from the starting point among the sequentially arranged wireless devices 5. For example, when wireless device 5 is arranged with wireless device 5(a), wireless device 5(b), and wireless device 5(c), the second arrangement is formed by arranging the response time between wireless device 5(a) and wireless device 5(b), the response time between wireless device 5(a) and wireless device 5(c), and the response time between wireless device 5(b) and wireless device 5(c) in sequence.

[0128] In this embodiment, the response time between wireless device 5(a) and wireless device 5(b) is y1, the response time between wireless device 5(a) and wireless device 5(c) is y2, and the response time between wireless device 5(b) and wireless device 5(c) is y3. In this case, the second set with response time as an element includes y1, y2, and y3.

[0129] The estimation unit 10 selects any one of the wireless devices 5(a) to 5(c) as the starting point. When the estimation unit 10 selects the wireless device 5(a) as the starting point, the estimation unit 10 arranges the plurality of wireless devices 5 in order of the response time between them and the wireless device 5(a) as the starting point from the smallest to the largest. The estimation unit 10 arranges the response time based on the order of the arrangement. For example, when the response time between the wireless device 5(b) and the wireless device 5(a) as the starting point is smaller than the response time between the wireless device 5(c) and the wireless device 5(a) as the starting point, the estimation unit 10 arranges the plurality of wireless devices 5 in the order of the wireless device 5(a), the wireless device 5(b), and the wireless device 5(c).

[0130] Then, the estimation unit 10 arranges the response time in the order of response time y1, response time y2, and response time y3, and defines the arrangement [y1, y2, y3] of the arrangement as a second arrangement. The estimation unit 10 treats the response time as an element of the second arrangement and the identification numbers of the two wireless devices 5 related to the response time as one group. In this example, the estimation unit 10 treats y1, a, and b as one group, y2, a, and c as one group, and y3, b, and c as one group. Fig.10 A graph showing the relationship between the identification number of the wireless device 5 and the response time is included. Fig.10 In the figure, the number on the upper right of each grid indicates the rank of the element in the arrangement.

[0131] The estimating unit 10 defines a group of permutations that can be selected from the first set with the distance between objects as an element as a second permutation group. When the number of elements included in the first set with the distance between objects as an element is set to m, the second permutation group is a group of permutations (also referred to as sorting) obtained by selecting m elements from the m elements. For example, Fig. 9 As shown in FIG. 1 , when the elements of the distance between objects are three, namely, x1, x2, and x3, there are six arrangements of the elements of the second arrangement group, namely, [x1, x2, x3], [x1, x3, x2], [x2, x1, x3], [x2, x3, x1], [x3, x1, x2], and [x3, x2, x1]. The estimation unit 10 processes the distance between objects, which are the elements of the arrangement, and the identification numbers of the two objects 4 related to the distance between objects as one group. Specifically, the estimation unit 10 processes x1, A, and B as one group, x2, A, and C as one group, and x3, B, and C as one group.

[0132] like Fig.10 As shown, the estimating unit 10 determines the arrangement closest to the second arrangement from the second arrangement group as a similar arrangement.

[0133] Fig.10 : is a diagram showing the second array related to response time, the similar array related to the distance between the objects closest to the second array, the approximation index SM derived from the two arrays, the correspondence between the identification numbers of the two objects 4 and the identification numbers of the two wireless devices 5, and the correspondence between the objects 4 and the wireless devices 5. In this example, the similar array related to the response time closest to the second array is Fig. 9 The arrangement R3[x2, x1, x3]. Fig.10 In the example, the elements of the similar arrangement [x2, x1, x3] are arranged such that the arrangement of the elements from the first rank to the third rank of the similar arrangement ( Fig.10 The configuration in the table of ) and the configuration from the first element to the third element in the second arrangement ( Fig.10 The configuration in the table is equal.

[0134] The estimating unit 10 estimates the combination of the object 4 and the wireless device 5 based on the comparison between the second arrangement and the similar arrangement.

[0135] Specifically, the estimation unit 10 establishes a correspondence between the first-ranked element of the second arrangement and the first-ranked element of the similar arrangement. The estimation unit 10 establishes a correspondence between the second-ranked element of the second arrangement and the second-ranked element of the similar arrangement. The estimation unit 10 establishes a correspondence between the third-ranked element of the second arrangement and the third-ranked element of the similar arrangement.

[0136] Based on the correspondence, the estimation unit 10 establishes a correspondence between the identification numbers of the two wireless devices 5 corresponding to the first-order element of the second array and the identification numbers of the two objects 4 corresponding to the first-order element of the similar array. The estimation unit 10 establishes a correspondence between the identification numbers of the two wireless devices 5 corresponding to the second-order element of the second array and the identification numbers of the two objects 4 corresponding to the second-order element of the similar array. The estimation unit 10 establishes a correspondence between the identification numbers of the two wireless devices 5 corresponding to the third-order element of the second array and the identification numbers of the two objects 4 corresponding to the third-order element of the similar array.

[0137] The estimation unit 10 determines the corresponding relationship between the identification numbers of the two wireless devices 5 and the identification numbers of the two objects 4 (“the corresponding relationship between the two objects 4 and the two wireless devices 5”, see Fig.10 ), for each of the identification numbers of the wireless devices 5, the identification numbers of the objects 4 corresponding to the identification numbers of the wireless devices 5 are derived (refer to Fig.10 of objects and wireless devices).

[0138] Reference Fig.10 A specific example will be described. Fig.10 In the example of "the correspondence between two objects and two wireless devices", the identification numbers "a" and "b" of the wireless devices correspond to the identification numbers "A" and "C" of the object 4, and the identification numbers "b" and "c" of the wireless device 5 correspond to the identification numbers "B" and "C" of the object 4. In this case, "b" and "C" are included in both the former correspondence and the latter correspondence. Thus, the inference unit 10 infers that "b" and "C" are in a corresponding relationship. Based on this inference, the inference unit 10 infers that "a" and "A" are in a corresponding relationship according to the former correspondence. Furthermore, the inference unit 10 infers that "c" and "B" are in a corresponding relationship according to the latter correspondence. This relationship is similar to the correspondence between the identification numbers "c" and "a" of the wireless device 5 and the identification numbers "A" and "B" of the object 4 as the third correspondence ( Fig.10 The third column of “the correspondence between the two objects and the two wireless devices” in FIG.

[0139] The effects of this embodiment will be described.

According to this structure, the combination of the object 4 and the wireless device 5 in the configuration pattern can be estimated based on the information including the response time between the wireless devices 5 and the information related to the configuration pattern of the object 4. As a result, the configuration of the object 4 can be accurately estimated in a manner corresponding to the wireless device 5.

[0141] (2) The estimating unit 10 estimates the combination of the object 4 and the wireless device 5 in the configuration pattern based on the first information and the second information. The estimating unit 10 obtains the inherent information of the object 4 connected to the wireless device 5 from the wireless device 5, and establishes a correspondence between the inherent information of the object 4 and the object 4 in the configuration pattern based on the combination of the object 4 and the wireless device 5 in the configuration pattern and the inherent information of the object 4. According to this structure, the configuration of the object 4 can be estimated in a manner that the configuration is associated with the inherent information of the object 4.

[0142] (3) The estimating unit 10 determines the arrangement closest to the second arrangement from the second arrangement group as a similar arrangement, and estimates the combination of the object 4 and the wireless device 5 based on the comparison between the second arrangement and the similar arrangement. According to this configuration, by repeating a simple procedure, the arrangement closest to the second arrangement can be determined from the second arrangement group, and based on this determination, the combination of multiple objects 4 and multiple wireless devices 5 can be estimated.

[0143] (4) In the estimation method of the present embodiment, the estimation unit 10 obtains information related to the configuration pattern of the object 4 as the first information, and obtains information including the response time between the wireless devices 5 from the wireless device 5 connected to the object 4 as the second information.

According to this structure, the combination of the object 4 and the wireless device 5 in the configuration pattern can be estimated based on the information including the response time between the wireless devices 5 and the information related to the configuration pattern of the object 4. As a result, the configuration of the object 4 can be accurately estimated in a manner corresponding to the wireless device 5.

[0144] <Third Embodiment>

[0145] Reference Fig.11 , the estimation system 1 of the third embodiment is described. The estimation system 1 of this embodiment is different from the estimation system 1 of the first embodiment and the second embodiment in that information other than the first information and the second information is used. In the following description, the same reference numerals are marked on the components common to the estimation system 1 of the first embodiment, and their description is omitted. The technology of this embodiment can be applied to any one of the first embodiment and the second embodiment.

[0146] The estimating unit 10 acquires the third information about the object 4 and the fourth information about the wireless device 5 .

[0147] The third information related to the object 4 is information for identifying the object 4. Examples of the third information include the usage number of the object 4 and the model number of the object 4. The estimation unit 10 can obtain the third information through an input operation from a keyboard. The estimation unit 10 can obtain the third information from two-dimensional information, three-dimensional information, or a layout diagram including position information of a plurality of objects 4. The estimation unit 10 stores the third information in correspondence with the identification number of the object 4.

[0148] The fourth information related to the wireless device 5 is information associated with the third information of the object 4 to which the wireless device 5 is connected.

[0149] Specifically, the fourth information related to the wireless device 5 is information related to the third information transmitted from the wireless device 5 connected to the object 4 having the third information. The wireless device 5 outputs the information related to the third information of the object 4 to the estimation unit 10 as the fourth information. For example, the wireless device 5 obtains the usage number of the object 4 from the object 4 as the third information, and outputs the usage number as the fourth information. The estimation unit 10 stores the fourth information in association with the identification number of the wireless device 5.

[0150] The estimating unit 10 estimates the combination of the object 4 and the wireless device 5 in the arrangement pattern based on at least the first information, the second information, the third information, and the fourth information.

[0151] The estimating unit 10 estimates the combination of the object 4 and the wireless device 5 in the configuration pattern by the method described in the first embodiment or the second embodiment based on the first information and the second information. If multiple combinations are found, the estimating unit 10 reduces the combination of the object 4 and the wireless device 5 to one based on the third information and the fourth information.

[0152] For example, in object 4, the configuration mode is Fig.11 In the case of the pattern shown in FIG. 1 , the object 4 (B) and the object 4 (C) are at the same distance from the object 4 (A) and the object 4 (D). In such a case, the estimating unit 10 outputs two results about the combination of the object 4 and the wireless device 5 by estimation. In this case, the estimating unit 10 estimates the combination of the object 4 and the wireless device 5 based on the third information, the identification number of the object 4 corresponding to the third information, the fourth information obtained from the wireless device 5, and the identification number of the wireless device 5 corresponding to the fourth information.

[0153] Fig.12 4 is a diagram showing a combination of an object 4 and a wireless device 5 estimated based on the first information and the second information. In this example, two estimation results are shown. Fig.12 The parts surrounded by dotted lines are different. Fig.12 In , "Z" is the third information. The third information (Z) corresponds to object 4 (C). Fig.12 In , "z" is the fourth information. The fourth information (z) corresponds to the wireless device 5 (b). Since the fourth information (z) is information associated with the third information (Z), the inference unit 10 establishes a correspondence between the object 4 (C) and the wireless device 5 (b). The inference unit 10 infers the combination of the object 4 and the wireless device 5 based on the combination of the object 4 and the wireless device 5 inferred based on the first information and the second information, and the combination of the object 4 and the wireless device 5 inferred based on the third information and the fourth information. Fig.12 In the example of , the estimating unit 10 determines that the upper combination is the most appropriate combination.

[0154] The effects of this embodiment will be described.

[0155] The estimation unit 10 obtains third information related to the object 4 and fourth information related to the wireless device 5 and associated with the third information. The estimation unit 10 estimates the combination of the object 4 and the wireless device 5 based on at least the first information, the second information, the third information, and the fourth information. According to this configuration, information associated with the object 4 and the wireless device 5 is used in estimating the combination. As a result, the estimation accuracy of the combination between the object 4 and the wireless device 5 in the configuration pattern can be improved.

[0156] <Fourth embodiment>

[0157] The estimation system 1 of the fourth embodiment is described. The estimation system 1 of this embodiment is different from the estimation system 1 of the first to third embodiments in that at least one of the first information and the second information is processed. In the following description, the same reference numerals are given to the components common to the estimation system 1 of the first embodiment, and the description thereof is omitted. The technology of this embodiment can be applied to any one of the first to third embodiments.

[0158] There are situations where the distance between objects cannot be accurately obtained. In addition, the response time cannot be accurately measured sometimes. In such a situation, the estimation unit 10 cannot correctly determine the similar arrangement. In the case where the similar arrangement cannot be correctly determined, the estimation unit 10 preferably lists a plurality of candidates. For example, in the case where there are two groups of objects 4 with approximately equal differences in the distance between the objects among a plurality of objects 4, the estimation unit 10 regards the two approximately equal distances between the objects as equal distances. In the case where there are two groups of wireless devices 5 with approximately equal differences in response time among a plurality of wireless devices 5, the estimation unit 10 regards the two approximately equal response times as equal response times. Specific examples are given below.

[0159] The estimating unit 10 executes preprocessing before estimating the combination of the object 4 and the wireless device 5 .

[0160] As preprocessing, the estimation unit 10 compares a plurality of inter-object distances with respect to the first information, and when a difference between the inter-object distances is less than a predetermined value, changes the values ​​of the plurality of inter-object distances in such a manner that the plurality of inter-object distances whose differences between the inter-object distances are less than the predetermined value become equal values ​​to one another.

[0161] The estimating unit 10 compares the plurality of response times with respect to the second information, and when a difference between the response times is less than a predetermined value, changes the values ​​of the plurality of response times so that the plurality of response times having a difference between the response times less than the predetermined value become equal to each other.

[0162] The estimating unit 10 estimates the combination of the object 4 and the wireless device 5 based on the preprocessed first information and second information. In this case, the estimating unit 10 outputs a plurality of results as the combination of the object 4 and the wireless device 5 as candidates.

[0163] The effects of this embodiment will be described.

[0164] The estimating unit 10 performs the above-described preprocessing on the first information and the second information before estimating the combination of the object 4 and the wireless device 5. According to this configuration, the following effects can be obtained.

[0165] The distance between objects and the response time have errors. If the combination of the object 4 and the wireless device 5 is estimated based on the distance between objects and the response time containing errors, the combination between the object 4 and the wireless device 5 may not be estimated correctly. In such a case, it is preferable not to estimate the relationship between the object 4 and the wireless device 5 in a one-to-one relationship, but to output multiple results. In this regard, according to the above-mentioned structure, when the difference in the distance between objects is less than a specified value, or when the difference in the response time is less than a specified value, the estimation result can be derived in a manner that does not estimate the object 4 and the wireless device 5 in a one-to-one relationship. In this way, when the object 4 and the wireless device 5 cannot be accurately estimated in a one-to-one relationship, multiple estimation results can be obtained, so the correct combination can be found from the selected multiple estimation results.

[0166] <Modification>

[0167] The estimation system 1 of the present disclosure may be a mode in which, in addition to the above-described embodiments, for example, the following modified examples and at least two modified examples that do not contradict each other are combined.

[0168] ·Reference Fig.13A modification of the estimation system 1 is described below. When the estimation unit 10 estimates a combination of a plurality of objects 4 and a plurality of wireless devices 5 connected to the objects 4, the starting point information can be obtained. The starting point information is information related to the combination of the object 4 and the wireless device 5 determined in advance by action confirmation. The estimation unit 10 can obtain information on the combination of the object 4 and the wireless device 5 selected in the first embodiment as the starting point information. In addition, the starting point information is information not associated with the "starting point" of the embodiment.

[0169] In one example, the estimating unit 10 acquires at least one starting point information of the plurality of objects 4. The estimating unit 10 estimates the combination of the object 4 and the wireless device 5 based on the first information, the second information, and the starting point information.

[0170] For example, for any one of the plurality of objects 4, before estimation is performed based on the estimation system 1, a combination of the object 4 and the wireless device 5 is determined. Specifically, by moving the specified object 4, the identification number of the wireless device 5 transmitted from the wireless device 5 connected to the specified object 4 is obtained. The estimation unit 10 establishes a correspondence between the specified object 4 and the identification number of the wireless device 5 transmitted from the wireless device 5 connected to the specified object 4, and stores the correspondence as the starting point information.

[0171] Fig.13 is a diagram showing a combination of an object 4 and a wireless device 5 estimated based on the first information and the second information. Fig.13 Two inference results are shown in Fig.13 The parts surrounded by dotted lines are different.

[0172] exist Fig.13 In the example, object 4(B) corresponds to wireless device 5(d). The correspondence between object 4(B) and wireless device 5(d) is the starting point information. The estimation unit 10 determines the combination of the object and the wireless device based on the two combinations and the starting point information. Fig.13 In the example of , the estimating unit 10 determines that the upper combination is the most appropriate combination.

[0173] The effect of this example will be described.

[0174] The estimation unit 10 obtains the starting point information that specifies the combination of the object 4 and the wireless device 5, and estimates the combination of the object 4 and the wireless device 5 in the configuration pattern based on the starting point information, the first information, and the second information. According to this configuration, one group is specified among the groups consisting of the object 4 and the wireless device 5, so the estimation accuracy of the combination of other objects 4 and other wireless devices 5 can be improved.

[0175] Reference Fig.14 , other variations of the estimation system 1 are described.

[0176] For a management system 2 including a plurality of objects 4 and a plurality of wireless devices 5, the estimation unit 10 sometimes derives a plurality of results for a combination of an object 4 and a wireless device 5 in a configuration pattern. In this case, a specific wireless device 20 may be added as a virtual device in the configuration space DS. The specific wireless device 20 does not need to be configured in the configuration space DS, but is a virtual device used to estimate a combination of an object 4 and a wireless device 5. The specific wireless device 20 is a device that can communicate with the wireless device 5 and can be configured in the configuration space DS. The specific wireless device 20 may be an object that is an integral part of an object 4 and a wireless device 5 connected to the object 4, and is movable. By configuring such a specific wireless device 20, the estimation results of the combination of the object 4 and the wireless device 5 can be reduced.

[0177] like Fig.14 As shown, for example, when the configuration pattern of the object 4 is a configuration pattern in which the object 4 is configured at the vertices of a regular polygon, the estimation unit 10 outputs a plurality of estimation results for the combination of the object 4 and the wireless device 5. In this case, in the configuration space DS, the virtual device is configured at a position deviated from the center of the regular polygon. Furthermore, a mark of the virtual device is added to the configuration pattern of the object 4.

[0178] By such an operation, different inter-object distances increase between the plurality of objects 4 (including virtual devices), so that it is easy to determine the combination of the object 4 and the wireless device 5. Specifically, in a state where the specific wireless device 20 is arranged in the configuration space DS where the plurality of objects 4 are arranged, the estimation unit 10 defines the specific wireless device 20 as belonging to any of the object 4 and the wireless device 5. Then, the estimation unit 10 acquires information related to the configuration pattern of the plurality of objects 4 arranged in the configuration space DS and information related to the configuration pattern of the specific wireless device 20 as first information. Specifically, information obtained by adding the position information of the specific wireless device 20 to the map or three-dimensional information representing the configuration pattern of the object 4 is used as the first information. The estimation unit 10 acquires information including the response time between the wireless devices 5 in the plurality of wireless devices 5 from the group consisting of the wireless device 5 and the specific wireless device 20 as second information. The estimation unit 10 estimates the combination of the plurality of objects 4 including the specific wireless device 20 and the plurality of wireless devices 5 including the specific wireless device 20 based on the first information and the second information.

[0179] The effect of this example will be described.

[0180] The estimation system 1 further includes a specific wireless device 20. The estimation unit 10 defines the specific wireless device 20 as belonging to any of the object 4 and the wireless device 5. The estimation unit 10 obtains information related to the configuration pattern of the plurality of objects 4 and the specific wireless device 20 configured in the configuration space DS as first information. Furthermore, the estimation unit 10 obtains information including the response time between the wireless devices 5 in the plurality of wireless devices 5 from the wireless device 5 group including the wireless device 5 and the specific wireless device 20 as second information. The estimation unit 10 estimates the combination of the object 4 and the wireless device 5 in the configuration pattern based on the first information and the second information.

[0181] Since the specific wireless device 20 is defined as belonging to the object 4 and the wireless device 5, the specific wireless device 20 can be handled as a combination of the object 4 and the wireless device that is predetermined in the estimation of the combination of the object 4 and the wireless device. By arranging such a specific wireless device 20 at a predetermined position in the configuration space DS, a state is achieved in which one group is determined among the groups consisting of the object 4 including the specific wireless device 20 and the wireless device 5 including the specific wireless device 20, so that the estimation accuracy of the combination of other objects 4 and other wireless devices 5 can be improved. Other objects 4 refer to objects 4 other than the specific wireless device 20. Other wireless devices 5 refer to wireless devices 5 other than the specific wireless device 20.

[0182] ·like Fig.15 As shown, there is a management system 2 that manages multiple objects 4 configured in three dimensions. In the construction of such a management system 2, the inference system 1 is capable of inferring the combination of the object 4 and the wireless device 5 in the configuration pattern. In this example, the object 4 is an electric valve installed in the piping 22. The electric valve is connected to the wireless device 5. The wireless device 5 is connected to the management unit 3 via a connecting device 9. The connecting device 9 is, for example, a router. An example of the management unit 3 is a personal computer. In this example, the first information is three-dimensional information including the configuration of the electric valve. The second information is information including the response time between the wireless devices 5 respectively connected to the multiple electric valves. For such a management system 2, the relationship between the electric valve and the wireless device 5 can also be inferred by the same method as described above.

[0183] When the configuration space DS is wide, information may not be obtained from some of the wireless devices 5 configured in the configuration space DS. On the other hand, information may be obtained from all of the wireless devices 5 configured in the configuration space DS. When the number of objects 4 in the configuration space DS for which a combination is to be determined does not match the number of wireless devices 5, the combination cannot be determined.

[0184] Therefore, the estimation unit 10 can calculate the number difference between the number of objects 4 acquired based on the first information and the number of wireless devices 5 acquired based on the second information. The estimation unit 10 can estimate the combination of objects 4 and wireless devices 5 in the arrangement pattern when there is no number difference.

[0185] According to this configuration, when the number of objects 4 and the number of wireless devices 5 arranged in the configuration space DS match and there is no difference in number, the combination of the object 4 and the wireless device 5 is estimated. If the estimation is performed when there is a difference in number, the calculation will be invalid, but the estimation process performed when there is such a difference in number can be suppressed.

[0186] Furthermore, when there is a quantity difference, the estimation unit 10 determines a prescribed space in the configuration space DS that includes the same number of objects 4 as the number of wireless devices 5. The prescribed space is a space within the configuration space DS. The estimation unit 10 determines the prescribed space according to a prescribed rule based on the configuration space DS. The estimation unit 10 can obtain information related to a configuration pattern of a plurality of objects 4 configured in the prescribed space from the first information as the first information on the basis of determining the prescribed space, and estimate the combination of the objects 4 and the wireless devices 5 in the configuration pattern based on the first information and the second information. According to this structure, even when the number of objects 4 configured in the configuration space DS is inconsistent with the number of wireless devices 5 and there is a quantity difference, the combination of the objects 4 and the wireless devices 5 can be estimated.

[0187] - Although the embodiment of the estimation system 1 has been described above, it should be understood that various changes in form and details may be made without departing from the gist and scope of the estimation system 1 described in the claims.
