[0013] (Embodiment 1) An example of the configuration of the monitoring device 10 will be described below with reference to Fig. 1. The monitoring device 10 may be a computer device that operates when a processor executes a program stored in a memory. The monitoring device 10 may also be an information processing device.

[0014] The monitoring device 10 has a generating unit 11, an identifying unit 12, and an output unit 13. The generating unit 11, the identifying unit 12, and the output unit 13 may be software or a module that performs processing by a processor executing a program stored in a memory. Alternatively, the generating unit 11, the identifying unit 12, and the output unit 13 may be hardware such as a circuit or a chip.

[0015] The generating unit 11 generates three-dimensional data including facilities in a three-dimensional space. The facilities may include, for example, buildings, roads, plants, etc. The facilities may be, for example, equipment such as substations. The three-dimensional data may be, for example, data indicating the three-dimensional positions of facilities included in the three-dimensional space. That is, the three-dimensional data may be referred to as a three-dimensional map indicating the positions of facilities, etc. The three-dimensional data may be generated based on data measured using a sensor or the like. Alternatively, the three-dimensional data may be generated using software that generates three-dimensional data from two-dimensional data such as drawings. The three-dimensional data may be, for example, point cloud data. Alternatively, the three-dimensional data may be mesh data, polygon data, etc. generated using point cloud data. Alternatively, the three-dimensional data may be data represented using a depth map.

[0016] The identification unit 12 identifies the movement of a worker in the three-dimensional data based on the position of the worker in the facility in the three-dimensional data and the sensor data generated by a sensor attached to the worker. The three-dimensional data may be data indicating the position of the facility, for example, using a predetermined coordinate system. The predetermined coordinate system may be a coordinate system converted from a world coordinate system representing an actual three-dimensional space according to a predetermined criterion. The predetermined criterion may be determined using, for example, a scale, a rotation angle, a matrix, or the like. In other words, a position in the world coordinate system may be converted to a position in the predetermined coordinate system according to a predetermined conversion formula.

[0017] The position of a worker in a facility in the three-dimensional data may be, for example, a position of the worker in the facility after the position determined in a world coordinate system is converted into a predetermined coordinate system indicating the three-dimensional data. The position of the worker in the three-dimensional data may be, for example, the position of a device used to measure the position of the worker. The device used to measure the position of the worker may be attached or affixed to the worker. Alternatively, the device used to measure the position of the worker may be stored in a pocket or the like of the worker's clothes.

[0018] The sensor attached to the worker may be, for example, a motion sensor, a temperature sensor, a sensor that emits light, a sensor that emits heat, etc. More specifically, the motion sensor may be an acceleration sensor. Alternatively, the motion sensor may be configured by an acceleration sensor, a gyro sensor, etc.

[0019] The worker's movement may be, for example, a movement of a sensor attached to the worker. Identifying the worker's movement may be, for example, identifying a position or a transition of a position of the sensor attached to the worker.

[0020] The output unit 13 outputs warning information when the sensor enters a danger area. The danger area may be, for example, the vicinity of energized equipment in a substation. The vicinity of energized equipment may be, for example, an area within a predetermined distance from the energized equipment. The danger area may also be changed by changing the energized parts in the equipment.

[0021] The intrusion of the sensor into the dangerous area may be when a worker approaches the dangerous area and the sensor attached to the worker enters the dangerous area. In other words, the intrusion of the sensor into the dangerous area may be when a part of the body of the worker to which the sensor is attached enters the dangerous area.

[0022] The warning information may be output as a sound that can be sensed by hearing, or may be output as a light that can be sensed by sight. Alternatively, the warning information may be transmitted to a communication device or the like held by the worker. In this case, the communication device that receives the warning information may output a sound, a light, or the like, may display a message indicating the warning information on a display, or may vibrate the communication device itself.

[0023] Next, the flow of the monitoring process executed by the monitoring device 10 will be described with reference to Fig. 2. First, the generating unit 11 generates three-dimensional data including a facility in a three-dimensional space (S11). Next, the identifying unit 12 identifies the movement of a worker in the three-dimensional data based on the position of the worker in the facility in the three-dimensional data and sensor data generated by a sensor attached to the worker (S12). Next, the output unit 13 outputs warning information when the sensor enters a dangerous area (S13).

[0024] As described above, the monitoring device 10 identifies the motion of the worker in the three-dimensional data by using the position of the worker in the three-dimensional data and the sensor data generated by the sensor attached to the worker. Furthermore, the monitoring device 10 outputs warning information when the sensor enters a dangerous area. In this way, even if most parts of the worker's body are not within the dangerous area, the monitoring device 10 can output warning information when some parts of the worker's body enter the dangerous area. As a result, the monitoring device 10 can support the worker to whom the sensor is attached to perform the work safely.

[0025] 1 shows that the generating unit 11, the identifying unit 12, and the output unit 13 are included in one monitoring device 10, but the generating unit 11, the identifying unit 12, and the output unit 13 may be provided in different devices. In this case, the generating unit 11, the identifying unit 12, and the output unit 13 may transmit and receive information via a network. Alternatively, one of the generating unit 11, the identifying unit 12, and the output unit 13 may be provided in a device different from the other components.

[0026] 2 may be performed as an independent process unrelated to steps S12 and S13. That is, after the generator 11 generates the three-dimensional data, the processes related to steps S12 and S13 may be performed at any timing.

[0027] (Embodiment 2) Next, a configuration example of the monitoring system will be described with reference to FIG. 3. The monitoring system of FIG. 3 includes a sensor 21, a sensor 22, a monitoring device 30, and a communication device 40. The monitoring device 30 communicates with the sensor 21, the sensor 22, and the communication device 40 via a network 50. FIG. 3 shows an example in which two sensors are connected to the network 50, but the number of sensors may be one or three or more. FIG. 3 also shows an example in which the sensor 21 and the sensor 22 are directly connected to the network 50, but for example, the sensor 21 and the sensor 22 may be connected to the network 50 via the communication device 40. Specifically, the sensor 21 and the sensor 22 may communicate with the communication device 40 that operates as an access point as a slave device in wireless LAN (Local Area Network) communication.

[0028] The sensor 21, the sensor 22, and the communication device 40 may be held by a single worker. Holding the sensor 21, the sensor 22, and the communication device 40 also includes being attached to the worker.

[0029] Here, the sensor 21 may be a GPS (Global Positioning System) sensor. The sensor 21 may be referred to as a measuring device that measures location information. The sensor 21, which is a GPS sensor, may be built into the communication device 40. The sensor 22 may be a motion sensor. A worker may be fitted with multiple motion sensors, rather than only one motion sensor. In other words, a worker may be fitted with multiple sensors 22.

[0030] The sensor 21 generates sensor data indicating the position of the sensor 21. The sensor data indicating the position of the sensor 21 is represented using a world coordinate system.

[0031] The sensor data indicating the position of the sensor 22 may be represented using a world coordinate system or a predetermined coordinate system. The predetermined coordinate system may be, for example, a coordinate system based on the sensor 22, or a coordinate system commonly used to indicate the positions of a plurality of sensors 22. The sensor 22 may be combined with another sensor, such as a geomagnetic sensor, to generate sensor data indicating the position of the sensor 22 in the world coordinate system.

[0032] The communication device 40 receives the warning information transmitted from the monitoring device 30. When the communication device 40 receives the warning information, the communication device 40 may vibrate the communication device 40 or may output a sound indicating a warning from an output speaker. Alternatively, the communication device 40 may display the warning information on a display.

[0033] The network 40 may be, for example, an IP (Internet Protocol) network. The network 40 may be an open network such as the Internet, or a closed network such as an intranet.

[0034] Here, the sensors attached to the worker will be described with reference to Fig. 4. Fig. 4 shows that one sensor 21 as a GPS sensor and multiple sensors 22 as motion sensors are attached to the worker. Fig. 4 shows that the sensor 21 is attached to the worker's torso. Fig. 4 also shows that the sensor 22 is attached to the extremities of the worker. Specifically, Fig. 4 shows that the sensors 22 are attached to the head, feet, and hands of the worker.

[0035] Further, Fig. 4 shows a safe area and a dangerous area. Fig. 4 shows that the torso of the worker is present in the safe area. The dotted line shows the boundary between the safe area and the dangerous area. Fig. 4 shows that the sensor 22 attached to the hand of the worker is present on the boundary. In this way, the monitoring device 30 may output warning information when the sensor attached to the worker enters the dangerous area including the boundary.

[0036] Next, a configuration example of the monitoring device 30 will be described with reference to Fig. 5. The monitoring device 30 in Fig. 5 has a configuration in which a determination unit 31 and a communication unit 32 are added to the monitoring device 10 in Fig. 1. In the description of the monitoring device 30, detailed description of operations or functions similar to those of the monitoring device 10 will be omitted. Furthermore, each of the components constituting the monitoring device 30 may be included in one device as shown in Fig. 5, or may be distributed and arranged in different devices.

[0037] The generating unit 11 generates point cloud data as three-dimensional data. The generating unit 11 may generate the point cloud data by using, for example, LiDAR (Light Detection And Ranging). The LiDAR device may be called a laser scanner. The generating unit 11 may use a LiDAR device. Alternatively, the generating unit 11 may acquire the point cloud data generated in the LiDAR device from the LiDAR device via a network or the like.

[0038] The LiDAR device measures the distance to an object using, for example, a ToF (Time of Flight) method, and generates points that indicate the shape of the object. A collection of points that indicate the shape of the object becomes point cloud data. The points that indicate the shape of the object may be specified using three-dimensional coordinates in a predetermined space. In other words, the points that indicate the shape of the object may be indicated using three-dimensional coordinates in a predetermined coordinate system.

[0039] The identification unit 12 identifies the position of the sensor 21 attached to the worker as the position of the worker. The position of the sensor 21 may be a position identified using a GPS. Furthermore, the identification unit 12 identifies the sensor 22 associated with the sensor 21 as a sensor attached to the same worker as the worker to which the sensor 21 is attached.

[0040] For example, the identification unit 12 may identify that the sensor 21 and the sensor 22 existing within a predetermined range from the sensor 21 are attached to the same worker. The sensor 22 generates sensor data indicating a position where the sensor 22 is attached as a motion sensor. When the sensor data indicates a position in a world coordinate system, the identification unit 12 determines whether or not the sensor data indicates a position within a predetermined range from the sensor 21. When the sensor data indicates a position in a predetermined coordinate system, the identification unit 12 may convert the position indicated by the sensor data into the world coordinate system and determine whether or not the converted position indicates a position within a predetermined range from the sensor 21. Alternatively, the identification unit 12 may convert the coordinate system used for the positions indicated by the sensor 21 and the sensor 22 into the coordinate system used for the point cloud data. The identification unit 12 may determine whether or not the sensor 22 exists at a position within a predetermined range from the sensor 21 by using information indicating the positions of the sensor 21 and the sensor 22 converted into the coordinate system used for the point cloud data.

[0041] Alternatively, the identification unit 12 may determine whether the sensors 21 and 22 are attached to the same worker by using identification information included in the measurement data generated by the sensor 21 and identification information included in the sensor data generated by the sensor 22. The identification unit 12 may determine that the sensors 21 and 22 are attached to the same worker when the identification information included in the measurement data generated by the sensor 21 matches the identification information included in the sensor data generated by the sensor 22. The same identification information may be input in advance to the sensors 21 and 22 attached to the same worker.

[0042] The determination unit 31 determines whether the sensor 22 has entered a danger area. The danger area in the three-dimensional data may be set, for example, by an administrator who manages the monitoring device 30 or a supervisor who monitors workers using the monitoring device 30. For example, the administrator may specify an area around an energized facility as the danger area. The administrator may input the location of the danger area into the point cloud data generated by the generation unit 11.

[0043] The determination unit 31 determines whether the position of the sensor 22 in the three-dimensional data has entered a dangerous area. The determination unit 31 may also determine whether the position of the sensor 21 in the three-dimensional data has entered a dangerous area. The determination unit 31 outputs the determination result to the output unit 13.

[0044] When the determination unit 31 determines that the position of at least one of the sensors 21 and 22 has entered the dangerous area, the output unit 13 may display warning information on the display of the monitoring device 30. Alternatively, the output unit 13 may output the warning information from the speaker as a warning sound. By recognizing the warning information output from the display or speaker, the manager or the like recognizes that the worker has entered the dangerous area.

[0045] When the determination unit 31 determines that the position of at least one of the sensors 21 and 22 has entered a dangerous area, the communication unit 32 transmits warning information to the communication device 40 held by the worker to which the sensor 21 and the sensor 22 are attached. The monitoring device 30 may manage, for example, information that associates the sensor 21 with the communication device 40 held by the worker to which the sensor 21 is attached. Specifically, the monitoring device 30 may manage the sensor 21 in association with destination information of the communication device 40 held by the worker to which the sensor 21 is attached.

[0046] The communication unit 32 transmits warning information to the communication device 40 held by the worker to whom the sensor determined to have entered the dangerous area is attached. When there are multiple workers in a facility, the communication unit 32 transmits warning information to the communication device held by the worker who has entered the dangerous area, thereby making it possible to avoid transmitting unnecessary warning information to workers who are working safely.

[0047] Alternatively, the communication unit 32 may also transmit the warning information to a communication device held by a worker who is in the vicinity of the worker who has entered the dangerous area. The workers who are in the vicinity of the worker who has entered the dangerous area may be determined based on the position indicated by the GPS sensor of each worker. That is, the communication unit 32 may transmit the warning information to a communication device held by a worker who is within a predetermined distance from the worker who has entered the dangerous area. The warning information may also include information for identifying the worker who has entered the dangerous area. This allows the worker who receives the warning information to take action, such as giving a warning to the worker who has entered the dangerous area.

[0048] Next, a configuration example of the communication device 40 will be described with reference to Fig. 6. The communication device 40 may be a computer device that operates when a processor executes a program stored in a memory.

[0049] The communication device 40 includes a communication unit 41 and an output unit 42. The communication unit 41 and the output unit 42 may be software or a module that performs processing by causing a processor to execute a program stored in a memory.

[0050] The communication unit 41 receives warning information from the monitoring device 30 via the network 50. The output unit 42 outputs the received warning information. For example, the output unit 42 may cause the warning information to be displayed on a display of the communication device 40. Alternatively, the output unit 42 may output a warning sound to a speaker of the communication device 40 as the warning information.

[0051] Next, the flow of the monitoring process in the monitoring device 30 will be described with reference to Fig. 7. First, the generating unit 11 generates point cloud data including facilities in a three-dimensional space (S21).

[0052] Next, the identification unit 12 acquires position information from the sensor 21, which is a GPS sensor attached to the worker (S22). The identification unit 12 acquiring the position information from the sensor 21 means that the identification unit 12 identifies the position of the sensor 21. The position information may indicate the position of the sensor 21 using, for example, latitude and longitude. Alternatively, the position information may indicate the position of the sensor 21 using coordinates in a world coordinate system.

[0053] Next, the identification unit 12 acquires sensor data of the sensor 22, which is a motion sensor (S24). The sensor data may be data indicating the position of the sensor 22 in a world coordinate system or a predetermined coordinate system. When the sensor data is data indicating the position in the predetermined coordinate system, the identification unit 12 may convert the position in the predetermined coordinate system into a position in the world coordinate system. The identification unit 12 may acquire sensor data from one motion sensor or from each of a plurality of motion sensors.

[0054] Next, the identification unit 12 identifies the sensor 22 attached to the same worker as the worker to which the sensor 21 is attached (S24). The identification unit 12 may identify that the sensor 21 and the sensor 22 present within a predetermined range from the sensor 21 are attached to the same worker. The identification unit 12 may determine whether the sensors 21 and 22 are attached to the same worker based on the positions in the world coordinate system. Alternatively, the identification unit 12 may convert the positions of the sensors 21 and 22 into the coordinate system used in the point cloud data. In this case, the identification unit 12 may determine whether the sensors 21 and 22 are attached to the same worker based on the positions in the coordinate system used in the point cloud data.

[0055] Alternatively, the identification unit 12 may determine whether the sensors 21 and 22 are attached to the same worker, using identification information included in the measurement data generated by the sensor 21 and identification information included in the sensor data generated by the sensor 22. The identification unit 12 may determine that the sensors 21 and 22 are attached to the same worker when the identification information included in the measurement data generated by the sensor 21 matches the identification information included in the sensor data generated by the sensor 22.

[0056] In step S24, it is assumed that the identification unit 12 has identified that the sensor 21 and the sensor 22 are attached to the same worker.

[0057] Next, the determination unit 31 determines whether the sensor 22, which is a motion sensor, has entered a dangerous area (S25). The dangerous area is set in the point cloud data. The determination unit 31 may determine whether the position of the sensor 22 in the point cloud data has entered the dangerous area.

[0058] When the determination unit 31 determines that the sensor 22, which is a motion sensor, has entered a dangerous area, the communication unit 32 transmits warning information to the communication device 40 (S26). The communication device 40 to which the warning information is transmitted is the communication device 40 held by the worker to which the sensor 22 is attached.

[0059] When the determination unit 31 determines that the sensor 22, which is a motion sensor, has not entered the dangerous area, the determination unit 31 repeats the process of step S25. The determination unit 31 may periodically determine whether or not the sensor 22, which is a motion sensor, has entered the dangerous area.

[0060] Next, a flow of a process for outputting warning information in the communication device 40 will be described with reference to Fig. 8. First, the communication unit 41 receives warning information from the monitoring device 30 (S31). Next, the output unit 42 outputs the warning information (S32). For example, the output unit 42 may cause the display of the communication device 40 to display the warning information. Alternatively, the output unit 42 may output a warning sound to a speaker of the communication device 40 as the warning information.

[0061] As described above, the monitoring device 30 uses the measurement data from the sensor 21 and the sensor data from the sensor 22 to determine whether the sensors 21 and 22 are attached to the same worker. Furthermore, the monitoring device 30 determines whether the sensor 22 has entered a dangerous area. As a result, even if the position of the sensor 21, which is generally recognized as the position of the worker, is outside the dangerous area, the sensor 22 attached to the end of the worker may be present within the dangerous area. In this case, the monitoring device 30 transmits warning information to the communication device 40 held by the worker. As a result, the worker can recognize that a part of his or her body has entered the dangerous area.

[0062] (Embodiment 3) Next, the process of identifying the position of the sensor 22 in the identification unit 12 will be described with reference to Fig. 9. The sensor 22 is, for example, a motion sensor. Fig. 9 also shows an image 60 in which the position of the sensor 22, which is a motion sensor, is indicated. For example, the image 60 may be an image displayed on an information processing device. The information processing device that displays the image 60 receives information indicating the position from the motion sensor and indicates the trajectory of the movement of the motion sensor. The position of the sensor 22 may be, for example, a camera coordinate determined by a camera that captured the image 60.

[0063] Here, the sensor 22, which is a motion sensor, may be attached at the same position as the sensor 21, which is a GPS sensor. The identification unit 12 identifies the distance between the sensor 22 attached at the same position as the sensor 21 and each sensor 22 attached to the worker's end. Furthermore, the identification unit 12 identifies the direction or orientation in which the sensor 22 attached to the worker's end is attached, using the sensor 21 as a reference.

[0064] Furthermore, the identification unit 12 identifies the position of the sensor 22 based on the direction or orientation identified as the position of the sensor 22 and the distance between the sensor 21 and the sensor 22, using the position of the sensor 21 identified in the point cloud data including the facilities in the three-dimensional space as a reference. By the identification unit 12 identifying the position of the sensor 22 in the point cloud data, the monitoring device 30 can generate warning information when the sensor 22 enters a dangerous area.

[0065] In this way, the determination unit 12 may determine the direction or orientation in which the sensor 22 is located relative to the sensor 21, and further determine the distance between the sensors 21 and 22, thereby determining the position of the sensor 22.

[0066] Furthermore, other than a motion sensor, for example, a temperature sensor, a sensor that emits light, or a sensor that emits heat may be used as the sensor 22, and the trajectory of the sensor may be shown in the image 60.

[0067] Fig. 10 is a block diagram showing a configuration example of a monitoring device 10, a monitoring device 30, and a communication device 40 (hereinafter referred to as the monitoring device 10, etc.). Referring to Fig. 10, the monitoring device 10, etc. includes a network interface 1201, a processor 1202, and a memory 1203. The network interface 1201 may be used to communicate with a network node. The network interface 1201 may include, for example, a network interface card (NIC) that complies with the IEEE 802.3 series. IEEE stands for Institute of Electrical and Electronics Engineers.

[0068] The processor 1202 reads out and executes software (computer programs) from the memory 1203 to perform the processing of the monitoring device 10 and the like described using the flowcharts. The processor 1202 may be, for example, a microprocessor, an MPU, or a CPU. The processor 1202 may include multiple processors.

[0069] The memory 1203 is configured by a combination of volatile memory and non-volatile memory. The memory 1203 may include storage located away from the processor 1202. In this case, the processor 1202 may access the memory 1203 via an I / O (Input / Output) interface (not shown).

[0070] 10, the memory 1203 is used to store a group of software modules. The processor 1202 can perform processing of the monitoring device 10, etc. by reading out the group of software modules from the memory 1203 and executing them.

[0071] As described with reference to FIG. 10, each of the processors included in the monitoring device 10 etc. executes one or more programs including a set of instructions for causing a computer to execute the algorithm described with reference to the drawing.

[0072] In the above examples, the program includes instructions (or software code) that, when loaded into a computer, cause the computer to perform one or more functions described in the embodiments.
