Description

[Technical Field]

[0001] The present invention relates to a management system. [Background technology]

[0002] To manage field devices such as sensors and actuators that make up an air conditioning control system, for example, construction information showing the construction status of each device is used. In this type of construction information, in addition to model information on the installed devices, identification information that identifies each device is required to operate the air conditioning control system. Since multiple devices of the same model are installed in the same control room, they cannot be distinguished by model information alone, so unique identification information is required for each device. This device identification information must be obtained from the actually installed devices and associated with each device in the construction information.

[0003] The identification information of the installed devices as described above is acquired from the devices that are actually installed in the field. To acquire such device information, for example, there is a technology that uses near field radio communication (NFC) (Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2023-136568 Summary of the Invention [Problem to be solved by the invention]

[0005] In order to set the identification information of the device acquired on-site in the construction information, it is necessary to confirm the correspondence between the device whose identification information has been acquired and the device in the construction information, and to associate the acquired identification information with the matching device in the construction information. With many devices installed, there has been a problem in that confirming the correspondence between the device whose identification information has been acquired and the device in the construction information as described above is time-consuming and places a burden on the person in charge.

[0006] The present invention has been made to solve the above problems, and aims to make it possible to confirm the correspondence between the device for which identification information has been obtained and the device in the construction information without much effort. [Means for solving the problem]

[0007] The management system of the present invention comprises a memory unit configured to store location information indicating the location where each of a plurality of devices arranged indoors is installed in correspondence with model information of the plurality of devices; a communication unit that performs wireless communication with each of the plurality of devices; a reception unit configured to receive model information and identification information for identifying the device sent from the device with which the connection has been established after the communication unit has established wireless communication; a position detection unit that sequentially detects the current position based on autonomous navigation; a route identification unit configured to identify the route taken by the position detected by the position detection unit; and a determination unit configured to determine the location of the device identified by the identification information received by the reception unit based on the route identified by the route identification unit, the detected position detected by the position detection unit when the reception unit receives the identification information, and the location information.

[0008] In one example of the configuration of the management system, the position detection unit detects a relative position with respect to a reference unit placed indoors that corresponds to a reference point set in the placement information.

[0009] In one example configuration of the above management system, the determination unit determines all virtual routes that pass through the installation positions of each of the multiple devices based on the model information received by the reception unit and the order in which the reception unit received the model information, and for each of all determined virtual routes, calculates and sums the difference between the detection position and the installation position in the order in which the virtual route passes through, and determines the device at the installation position whose difference from each detection position identified by the virtual route with the smallest calculated sum to be the device identified by the identification information received by the reception unit at the detection position.

[0010] In one configuration example of the management system described in claim 3, for devices whose model information has been received by the receiving unit second or later, the determination unit corrects the path from the most recent detection position to the current detection position by shifting it, taking the most recent detection position as the installation position, and calculates the difference between the detection position based on the corrected path and the installation position. [Effects of the Invention]

[0011] As described above, according to the present invention, the location of the equipment is determined based on the route obtained based on autonomous navigation, the detected position when the identification information was received, and the location information, so that the correspondence between the equipment for which identification information was obtained and the equipment in the construction information can be confirmed without much effort.

[Figure 7] FIG. 7 is a diagram showing the hardware configuration of a management system according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0013] A management system according to an embodiment of the present invention will now be described with reference to Fig. 1. This management system includes a storage unit 101, a communication unit 102, a reception unit 103, a position detection unit 104, a route identification unit 105, and a determination unit 106.

[0014] The storage unit 101 stores location information indicating the location where each of a plurality of devices is installed in an air conditioning control room (indoors) in association with model information of the plurality of devices. For example, the storage unit 101 stores a construction drawing in which the location where each of a plurality of devices is installed is associated with model information of the plurality of devices.

[0015] The communication unit 102 performs wireless communication with the above-mentioned devices. The communication unit 102 performs wireless communication using, for example, well-known near field radio communication (NFC). In this case, the communication unit 102 includes, for example, an NFC controller, an NFC antenna, and a nonvolatile memory. The communication unit 102 can also perform wireless communication using Bluetooth (registered trademark). The communication unit 102 can also perform wireless communication with an IC tag provided in the device using RFID (Radio Frequency Identification). The communication unit 102 can also perform wireless communication using ZigBee.

[0016] After the communication unit 102 establishes wireless communication, the reception unit 103 receives (acquires) model information and identification information for identifying the device sent from the device with which the connection has been established. For example, when the communication unit 102 performs wireless communication using NFC, after establishing short-range wireless communication by receiving a connection request from the device via NFC communication, the reception unit 103 acquires model information and identification information for identifying the device sent from the device that has issued the connection request.

[0017] The position detection unit 104 sequentially detects the current position based on autonomous navigation. The position detection unit 104 sequentially detects the relative position with respect to a reference point set in the placement information. The position detection unit 104 is equipped with, for example, an acceleration sensor that detects movement in three axes, the X-axis, the Y-axis, and the Z-axis, and detects position information relative to the reference point based on the detection values ​​of these acceleration sensors. The path identification unit 105 identifies the path taken by the position detected by the position detection unit. For example, feature points can be set at set intervals (time intervals) from among the detected positions, and vector data connecting the set feature points using a Bezier curve or the like can be used as path data. The feature points can include, for example, the detected position.

[0018] The determination unit 106 determines the location of the device identified by the identification information received by the reception unit 103 based on the route identified by the route identification unit 105, the detected position detected by the position detection unit 104 when the reception unit 103 received the identification information, and the location information.

[0019] The determination unit 106 first determines all virtual routes that pass through the installation positions of each of the multiple devices, based on the model information received by the reception unit 103 and the order in which the reception unit 103 received the model information. Furthermore, the determination unit 106 calculates and sums the difference between the detected position and the installation position for each of the determined virtual routes in the order in which the virtual routes pass through. The determination unit 106 determines the device at the installation position whose difference with each detected position identified by the virtual route with the smallest calculated sum to be the device identified by the identification information received by the reception unit 103 at the detection position. The determined result is displayed, for example, on a display device (not shown). Furthermore, the determination unit 106 can store the determined result in association with the information of the multiple devices stored in the storage unit 101.

[0020] Furthermore, the determination unit 106 corrects the current detected position by the difference between the immediately preceding detected position and the installation position, and obtains the difference between the corrected current detected position and the installation position.

[0021] After determining all the virtual routes, the determination unit 106 calculates, for example, as shown in FIG. 2, in a first step S101, the distance (error) between the detected position detected by the position detection unit 104 at the time when the reception unit 103 receives the model information (identification information) for the first time, the target virtual route, and the actual installation position of the equipment obtained from the placement information.

[0022] Next, in a second step S102, the distance (error) is calculated between the detected position detected by the position detection unit 104 at the time when the receiving unit 103 receives the model information (identification information), the target virtual route, and the actual installation position of the equipment obtained from the placement information.

[0023] The second step S102 is repeated (third step S103) until no more model information (identification information) is received by the receiving unit 103. Next, in a fourth step S104, the calculated errors are summed up to obtain the total error for the target virtual route.

[0024] The determination unit 106 performs steps S101 to S104 for all virtual routes.

[0025] For example, the storage unit 101 stores a construction drawing in which one device TH(1) with model information "TH", one device T(1) with model information "T", and three devices M(1), M(2), and M(3) with model information "M" are arranged at the positions indicated by white circles, as shown in Fig. 3. Also, a reference point SP is set on the construction drawing.

[0026] In the air conditioning control room shown in this construction drawing, when the person in charge obtains the model information and identification information of all the equipment, the five virtual routes shown in Table 1 below can be determined based on the order in which the identification information was obtained. In this example, since only one unit of model "TH" and model "T" has been installed, the order of "TH1" and "T1" can be determined from the beginning.

[0027] [Table 1]

[0028] The relative detected positions of each device detected by the position detection unit 104, the identification information received by the reception unit 103, and the route identified by the route identification unit 105 are, for example, as shown in Fig. 4. In Fig. 4, the detected positions are indicated by black circles.

[0029] In this example, the model "TH" with identification information 1001, the model "M" with identification information 1002, the model "T" with identification information 1003, the model "M" with identification information 1004, and the model "M" with identification information 1005 pass through in that order.

[0030] First, the first route 131 reaches the model "TH" with identification information 1001 from the reference point SP.

[0031] Next, the second route 132 goes from the model "TH" with identification information 1001 to the model "M" with identification information 1002.

[0032] Next, the third route 133 travels from the model "M" with identification information 1002 to the model "T" with identification information 1003.

[0033] Next, on the fourth route 134, the identification information 1003 of the model "T" reaches the identification information 1004 of the model "M".

[0034] Next, on the fifth route 134, the model "M" with identification information 1004 reaches the model "M" with identification information 1005.

[0035] Furthermore, as shown in FIG. 5, the determining unit 106 corrects the path from the immediately preceding detected position to the current detected position by shifting the path, assuming the immediately preceding detected position as the installation position.

[0036] To explain this correction using virtual route 1 as an example, first, for the second route 132, the immediately preceding detected position is shifted as the installation position of device TH(1) and corrected to obtain corrected second route 132a. Similarly, for the third route 133, the immediately preceding detected position is shifted as the installation position of device M(1) and corrected to obtain corrected third route 133a. Similarly, for the fourth route 134, the immediately preceding detected position is shifted as the installation position of device T(1) and corrected to obtain corrected fourth route 134a. Similarly, for the fifth route 135, the immediately preceding detected position is shifted as the installation position of device M(2) and corrected to obtain corrected fifth route 135a.

[0037] For devices whose identification information was acquired second or later, the determination unit 106 calculates the difference (distance) between the current detected position along the corrected route and the installation position. The destination of each corrected route is set as the corrected detected position, and the difference from the installation position is calculated as shown in FIG.

[0038] First, a difference Δ1 between the detected position of the black circle of the model "TH" whose identification information is 1001 and whose identification information is acquired first and the installation position of the white circle of the device TH(1) is calculated.

[0039] Next, the difference Δ2 between the detected position of the black circle for the model "M" whose identification information is 1002 and whose identification information was acquired second in order and the installation position of the white circle for device M(1) is calculated.

[0040] Next, a difference Δ3 between the detected position of the black circle for model “T” whose identification information is 1003 and whose identification information was acquired third in order, and the installation position of the white circle for device T(1) is calculated.

[0041] Next, a difference Δ4 between the detected position of the black circle for model "M" whose identification information is 1004 and whose identification information is the fourth to be acquired and the installation position of the white circle for device M(2) is calculated.

[0042] Next, a difference Δ5 between the detected position of the black circle for model "M" whose identification information is 1005 and whose identification information is the fifth to be acquired and the installation position of the white circle for device M(3) is calculated.

[0043] In the above manner, Δ1, Δ2, Δ3, Δ4, and Δ5 calculated for virtual route 1 are summed to obtain the total error for virtual route 1. In the same manner, the total error for virtual route 2, the total error for virtual route 3, the total error for virtual route 4, the total error for virtual route 5, and the total error for virtual route 6 are calculated.

[0044] For example, when the total error of virtual route 1 is the smallest, the determination unit 106 determines that the device at the installation position, whose difference from each detected position identified by virtual route 1 is calculated, is the device identified by the identification information received by the reception unit 103 at the detected position. In this case, it can be determined that device TH(1) has identification information 1001, device M(1) has identification information 1002, device T(1) has identification information 1003, device M(2) has identification information 1004, and device M(3) has identification information 1005.

[0045] 7, the management system according to the above-described embodiment is a computer device including a CPU (Central Processing Unit) 301, a main storage device 302, an external storage device 303, and a network connection device 304, and the above-described functions can be realized by the CPU 301 operating (executing) a program loaded in the main storage device 302. The network connection device 304 is connected to a network 305. The functions of the storage unit 101, the reception unit 103, the position detection unit 104, the route identification unit 105, and the determination unit 106 can be distributed among multiple computer devices.

[0046] As described above, according to an embodiment of the present invention, the location of equipment is determined based on the route obtained based on autonomous navigation, the detected position when identification information is received, and the location information, so that it is possible to confirm the correspondence between the equipment for which identification information has been obtained and the equipment in the construction information without much effort.
