<< 1. Overall configuration >>
As shown in FIG. 1, the plant equipment state collection system 1 includes a detection device 10, a network construction device 20, and a data storage device 30. A plurality of detection devices 10 are provided, and each detection device 10 is attached to a corresponding plant device among a plurality of plant devices arranged in a plant (not shown). The plurality of detection devices 10 can be connected to a wireless sensor network (WSN) using a standard such as a wireless local area network (LAN) and ZigBee (registered trademark) constructed by the network construction device 20. . The WSN is preferably a so-called mesh network. That is, a plurality of detection devices 10 are connected to the network construction device 20, and each detection device 10 (for example, the detection device 10-b) is one or more other detection devices 10 (for example, detection devices) that are adjacent to each other. 10-a and detection device 10-c) are also preferably connected. The mobile terminal 40 is used for storing information in the detection device 10 and acquiring information. When there is a detection device 10 (for example, detection device 10-a) that cannot be directly connected to the WSN due to a distance from the network construction device 20, the plant equipment state collection system 1 further includes a repeater 50. , WSN connectable range may be interpolated.

  The network construction device 20 is configured to be able to use a communication network. Communication networks include mobile networks such as 3G lines or LTE (Long Term Evolution) lines, local area networks such as wired LANs and wireless LANs, and wide area networks (WANs). Hereinafter, “a mobile network such as a 3G line or an LTE line” is also referred to as “3G / LTE”. The network construction device 20 is configured to be able to communicate with the data storage device 30 through a communication network.

  In the example shown in FIG. 1, three detection devices 10-a, 10-b, and 10-c are shown to be connected to the WSN constructed by the network construction device 20, but are connected to the WSN. The number of detection devices 10 may be four or more, or may be one or two. Further, the actual plant equipment state collection system 1 includes a plurality of network construction devices (the network construction device 20 in FIG. 1 and one or more other network construction devices not shown). Similarly to FIG. 1, a plurality of detection devices not shown are connected to one or more other network construction devices not shown.

  FIG. 2 shows an example of the internal configuration of each component of the plant equipment state collection system 1 shown in FIG. 2 includes a control unit 11, a detection unit 12, a network connection unit 13, a tag unit 14, and a notification unit 15. Since the detection device 10 is assumed to be attached to a place where it is difficult to supply power with a power cable or the like (not shown), it is preferable that the detection device 10 further includes a battery 16. In addition, the detection device 10 is a power source that controls the supply of power from the power cable or the battery 16 to at least one of the control unit 11, the detection unit 12, the network connection unit 13, the tag unit 14, and the notification unit 15, for example.

Moreover, the control part 11 may be comprised so that the remaining amount of the battery 16 can further be acquired, for example. The detection unit 12 of the detection device 10 detects the state of the plant equipment to which the detection device 10 is attached. Here, the plant equipment is, for example, a steam trap, a rotating machine, and the like, and the state of the plant equipment is, for example, temperature, vibration, humidity, pressure, ph (pH) of the plant equipment, and the like.

For example, it is configured such that it can be acquired by reading the information. Here, the non-contact means that the tag unit 14 of the detection apparatus 10 and the mobile terminal 40 are connected by, for example, a cable connection between the tag unit 14 of the detection apparatus 10 and the tag control unit 43 of the mobile terminal 40. This means that the tag control unit 43 does not make mechanical contact in a direct state or an indirect state. Further, for example, a sensor ID, which is specific information for specifying the detection device 10, is stored in advance in the tag unit 14, specifically, the tag IC 14-1.

The plant information (data 002) includes, for example, a plurality of network IDs, the sensor ID of the detection device 10 connected to the WSN identified by each network ID, the connection state of the detection device 10, and the mounting information (SM (Sensor module) mounting information), operating conditions (SM operating conditions) of the detection device 10, the state of the plant equipment, the detection value detected by the detection device 10, the worker ID, and the work content. The attachment information of the detection device 10 includes, for example, an attachment area such as an address in the plant. The operating conditions of the detection device 10 include, for example, detection items detected by the detection unit 12 of the detection device 10. Further, when there is a WSN to which the repeater 50 is connected, it may further include a repeater ID, a connection state to these WSNs, and attachment information of the repeater.

The tag control unit 43 stores information in the tag unit 14 of the detection device 10 and acquires information from the tag unit 14 by holding the mobile terminal 40 over the detection device 10, that is, for example, the mobile terminal 40 is detected by the detection device 10. It is automatically executed by approaching to a predetermined distance (for example, 10 cm). The speaker 44 of the portable terminal 40 outputs predetermined sound under the control of the control unit 41. The input unit 45 and the display unit 46 of the portable terminal 40 may be configured with touch panel display panel modules 45 and 46, for example.
