Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in IoT, prognostic management and the like are performed based on a vast amount of data acquired from a plurality of sensors of various types. And there was a problem that a large-capacity server for storing this vast amount of data was required, and the method of processing the vast amount of data including unnecessary data became complicated.

Means for Solving the Problems

[0005] The distribution device according to one embodiment detects with a sensor that a processing machine is in operation, and stores only the data during the operation period among the data collected by IoT.

Effects of the Invention

[0006] According to the distribution device of the present disclosure, the IoT data capacity that required a vast amount of data capacity can be reduced. [Brief explanation of the drawing]

[0007] [Figure 1] This is a block diagram showing the schematic configuration of the sorting device according to Embodiment 1. [Figure 2] This is a graph illustrating the distribution of the distribution device according to Embodiment 1. [Modes for carrying out the invention]

[0008] Embodiment 1 Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a block diagram showing the schematic configuration of a sorting device according to Embodiment 1. In Figure 1, the sorting device 10 includes a first sensor 11, a second sensor 12, a communication unit 13, a memory unit 14, and a control unit 15.

[0009] The first sensor 11 is a sensor that detects whether the processing machine 16 is performing processing. For example, the first sensor 11 is preferably a vibration sensor that can be attached to the processing machine 16. The first sensor 11 may also have a communication unit 13 and a communication circuit that can communicate over the internet.

[0010] The second sensor 12 is a sensor that detects data for predictive maintenance of the processing machine 16. For example, the second sensor 12 is preferably a microphone that converts the operating sound of the processing machine 16 into an electrical signal. The second sensor 12 may also have a communication unit 13 and a communication circuit that can communicate over the internet.

[0011] The communication unit 13 is a circuit that communicates with the first sensor 11 and the second sensor 12. The method by which the communication unit 13 communicates with the first sensor 11 and the second sensor 12 may be either wired or wireless. Furthermore, the communication unit 13 is preferably a communication circuit that can communicate over the Internet.

[0012] The memory unit 14 is a storage circuit that stores data detected by the second sensor 12. The memory unit 14 may also store data detected by the first sensor.

[0013] Based on the detection results of the first sensor 11, the control unit 15 stores the data detected by the second sensor 12 during the period when the processing machine 16 is performing processing in the memory unit 14. The control unit 15 also discards the data detected by the second sensor 12 during the period when the processing machine 16 is not performing processing.

[0014] Next, the data distribution will be explained. Figure 2 is a graph illustrating the data distribution of the distribution device according to Embodiment 1. The upper part of Figure 2 shows the vibration data detected by the first sensor 11. The lower part of Figure 2 shows the sound data detected by the second sensor 12. In Figure 2, the vertical axis represents the signal strength of the sensors, and the horizontal axis represents time. As shown in Figure 2, vibrations are generated when the processing machine is performing processing. The periods 23 and 24 during which vibrations 21 and 22 are detected by the first sensor 11 correspond to the period during which the processing machine is performing processing. The control unit 15 stores the data 25 and 26 detected by the second sensor during periods 23 and 24 in the memory unit 14. The control unit 15 also discards the data detected by the second sensor 12 outside of periods 23 and 24.

[0015] Thus, the distribution device of Embodiment 1 can reduce the IoT data capacity that previously required a massive amount of data.

[0016] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. For example, in Embodiment 1 described above, the period during which the processing machine is performing processing is determined by the presence or absence of vibration, but whether or not processing is in progress may also be determined by other means such as equipment temperature, motor current, or motor magnetism. Alternatively, whether or not processing is in progress may be determined by a combination of multiple sensors. Furthermore, the data to be selected may not be sound.

[0017] Each element described in the drawings as a functional block that performs various processes can be hardware-wise composed of a CPU, a memory, and other circuits, and software-wise realized by a program loaded in the memory or the like. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms by hardware, software, or a combination thereof, and are not limited to any of them.

[0018] Also, the above-described program can be stored using various types of non-transitory computer-readable media and supplied to a computer. Non-transitory computer-readable media include various types of tangible recording media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROM (Read Only Memory), CD-R, CD-R / W, semiconductor memories (e.g., mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (Random Access Memory)). Also, the program may be supplied to the computer by various types of transitory computer-readable media. Examples of transitory computer-readable media include electrical signals, optical signals, and electromagnetic waves. The transitory computer-readable media can supply the program to the computer via wired communication paths such as electric wires and optical fibers, or wireless communication paths.
