Japanese Patent Publication No. 7-35880 JP 2011-86012 A

By the way, in the plant equipment state collection system described in Patent Document 1, when the operation determination of the steam trap to be measured is performed, the person in charge operates in a specific transmission band associated with the desired steam trap. It is necessary to adjust the reception band of the reception unit of the determination device. Furthermore, in the plant equipment state collection system, it is necessary for a worker to carry and move the operation determination device so as to enter an area where the data transmitted by the detection device attached to the steam trap to be measured can be received. There is. If it does so, in the plant equipment state collection system indicated in patent documents 1, it is assumed that the discovery of the steam trap whose operation state is an abnormal state cannot be performed rapidly. This problem is expected to become more prominent as the plant grows larger and as plant equipment increases.

In order to solve this problem, for example, it is conceivable to connect a plurality of detection devices via a wireless network. By connecting a plurality of detection devices via a wireless network, it is possible to simultaneously determine the operation states of the plurality of steam traps without adjusting the reception band of the reception unit of the operation determination device for each steam trap to be measured. The idea of connecting plant devices via a wireless network is disclosed in Patent Document 2.

Also, in the plant, there are many manual operations such as maintenance work (repair and replacement), inspection work or daily operation work when the state of the plant equipment detected by the detection device is abnormal. In general, information related to work such as the device ID, work content, and work date and time of the detection device installed in the plant equipment that performed the work is manually input by the operator using a terminal in the plant. It is managed by sending it to the server as daily report information or filling it in a paper ledger.

However, in such a management method, the information input work is complicated, and the work date and time is input that relies on the memory of the worker, so there is room for improvement in terms of managing accurate work information. .

The present invention has been made in view of the above-described problems, and provides a plant equipment state collection system that can more accurately manage work information for plant equipment.

It should be noted that the present invention is not limited to the embodiments described below, and various modifications (including deletion of constituent elements) can be made without departing from the scope of the invention. .

<< 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, a data storage device 30, and a portable terminal 40. 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. Further, 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 sets the repeater 50. In preparation, the connectable range of the WSN may be interpolated.

The network construction device 20 is configured to be able to use mobile communication such as a 3G line or an LTE (Long Term Evolution) line. Hereinafter, “mobile communication such as 3G line or 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 via 3G / LTE. 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. Moreover, 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). As in FIG. 1, a plurality of detection devices not shown are connected to one or more other network construction devices not shown.

FIG. 2A shows an example of the internal configuration of each component of the plant equipment state collection system 1 shown in FIG. 2A 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. You may further have the control part 17. FIG. The power supply control unit 17 includes, for example, a self-holding circuit having a relay sequence or a switching element such as a transistor. Hereinafter, “detection device 10” is also referred to as “sensor module 10”. The detection apparatus 10 further includes a clock unit 18 that includes a predetermined clock circuit and clocks the date and time. The clock unit 18 is supplied with power from the battery 16 and always counts the date and time (including the date; the same applies hereinafter) regardless of the state of the power control unit 17.

The control unit 11 of the detection apparatus 10 controls the operation of 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.

The network connection unit 13 of the detection apparatus 10 is configured to be connectable to a WSN constructed by the network construction apparatus 20. The tag unit 14 of the detection device 10 is an RF (Radio Frequency) tag used for NFC (Near Field Communication), for example, having a tag IC 14-1 and a tag antenna 14-2. The tag unit 14 can be stored by the tag control unit 43 of the portable terminal 40, which will be described later, by writing information to the tag IC 14-1 in a non-contact manner, for example, and is stored in the tag IC 14-1 in a non-contact manner. 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 the tag unit 14, specifically, the tag IC 14-1 in advance.

The notification unit 15 of the detection device 10 is, for example, an LED, a buzzer, or the like, and is activated or stopped under the control of the control unit 11. The battery 16 of the detection device 10 supplies power to at least the control unit 11 when the detection device 10 is in the power ON state. For example, power may be supplied to the detection unit 12, the network connection unit 13, the tag unit 14, and the notification unit 15 via the control unit 11, or may be supplied without using the control unit 11. Also good.

2A includes a control unit 21, a 3G / LTE communication unit 22, a network construction unit 23, a storage unit 24, and a time measuring unit 25. Hereinafter, “network construction device 20” is also referred to as “sensor gate module 20”.

The control unit 21 of the network construction device 20 controls the operation of the 3G / LTE communication unit 22, the network construction unit 23, and the storage unit 24, for example. Since the network construction device 20 includes the 3G / LTE communication unit 22, the network construction device 20 can be connected to 3G / LTE. Moreover, the network construction device 20 can construct a WSN by having the network construction unit 23. The WSN constructed by the network construction device 20 is given, for example, a network ID, which is network identification information that identifies the WSN constructed by the specific network construction device 20.

The storage unit 24 of the network construction device 20 stores, for example, WSN network construction information (data 001) constructed by the network construction device 20 illustrated in FIG. 2B. The network construction information (data 001) includes, for example, a network ID, a sensor ID of the detection device 10 connected to the WSN specified by the network ID, and a list of connection states of these detection devices 10 to the WSN. When the repeater 50 is connected to the WSN specified by the network ID, the network construction information (data 001) may further include the repeater ID and the connection state of the repeater to the WSN. The time measuring unit 25 of the network construction device 20 includes a predetermined clock circuit and always measures the date and time (date and time).

The data storage device 30 shown in FIG. 2A includes a control unit 31, a 3G / LTE communication unit 32, a storage unit 33, and a time measuring unit. Hereinafter, the “data storage device 30” is also referred to as “cloud server 30”.

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), the operation condition (SM operation condition) of the detection device 10, the state of the plant equipment, and the detection value detected by the detection device 10. The attachment information of the detection device 10 includes, for example, an attachment area such as an address in the plant and an attachment device such as a pipe number to which the detection device 10 is attached. 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 plant information (data 002) includes all items of the network construction information (data 001). The timekeeping unit 34 of the data storage device 30 includes, for example, a radio clock circuit that can measure time and date with high accuracy, and always keeps time. In the present embodiment, the time measuring unit 34 measures the date and time (hereinafter also referred to as “WSN time”) which is a reference in the WSN. The data storage device 30 transmits WSN time information timed by the time measuring unit 34 to the detection device 10, the network construction device 20, and the repeater 50 via the WSN. The

timekeeping units

18, 25, 34, and 57 of the

devices

10, 20, and 50 that have received the WSN time information synchronize the date and time with the received WSN time information (time synchronization). As a result, the detection time, network construction device 20, data storage device 30, and repeater 50 connected to the WSN are always kept synchronized with the date and time that is counted internally. Note that the time synchronization method in the WSN is not limited to the above-described method, and other known methods can be used.

2A includes a control unit 41, a 3G / LTE communication unit 42, a tag control unit 43, a speaker 44, an input unit 45, a display unit 46, a time measuring unit 47, and a storage unit 48. Hereinafter, “portable terminal 40” is also referred to as “tablet terminal 40”.

The tag control unit 43 of the mobile terminal 40 includes a tag reader / writer 43-1 and a tag control antenna 43-2. 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). A specific operation of storing information in the tag unit 14 of the detection apparatus 10 and acquiring information from the tag unit 14 by the tag control unit 43 will be described later with reference to FIG. 2C. 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. Hereinafter, the “touch panel type

display panel modules

45 and 46” are also referred to as “

touch panels

45 and 46”. The timekeeping unit 47 of the portable terminal 40 includes a predetermined clock circuit and always keeps time. The storage unit 48 of the portable terminal 40 stores various information.

Further, for example, an application associated with the plant equipment state collection system 1 is installed in the portable terminal 40. For example, by executing this application, a person in charge working in the plant uses the portable terminal 40 to browse and edit the plant information (data 002) stored in the storage device 30, and the network of the detection device 10 It becomes possible to work such as connection. Hereinafter, the “application associated with the plant equipment state collection system 1” is also referred to as “plant application”. However, the person in charge of the work does not execute the plant application, for example, performs browsing and editing of plant information (data 002) stored in the storage device 30 using a WEB browser, network connection of the detection device 10, and the like. May be.

Furthermore, a plant manager can view and edit plant information (data 002) via 3G / LTE by using a communication terminal such as a notebook personal computer (not shown) that can be connected to 3G / LTE. it can. As a result, the person in charge of management can remotely monitor the state of the plant equipment without going directly to the plant equipment, and the person in charge carrying the portable terminal 40 when an abnormal state is found. It is possible to instruct repair work.

2A includes a control unit 51, a network connection unit 52, a tag unit 53, a notification unit 54, a battery 55, a power supply control unit 56, and a timing unit 57. The repeater 50 has an internal structure substantially similar to that of the detection device 10, but differs from the detection device 10 in that it does not have a detection unit.

With reference to FIG. 2C, an example of the operation of storing information in the tag unit 14 of the detection apparatus 10 and acquiring information from the tag unit 14 by the tag control unit 43 of the mobile terminal 40 will be described. In FIG. 2C, thin arrows in the figure represent signals such as commands, and thick arrows in the figure represent power supply. Further, the operations of storing information in the tag unit 53 of the repeater 50 and acquiring information from the tag unit 53 by the tag control unit 43 of the portable terminal 40 are the same, and thus description thereof is omitted.

When the portable terminal 40 is held over the detection apparatus 10, the tag control unit 43 of the portable terminal 40 generates, for example, a read signal or a write signal generated by the tag reader / writer 43-1 and a tag control antenna 43-2 generates, for example. The signal is transmitted to the detection device 10 in a radio wave or magnetic field. The tag unit 14 of the detection device 10 generates power in the tag antenna 14-2 by rectifying radio waves received by the tag antenna 14-2 or by electromagnetic induction by a received magnetic field. The tag antenna 14-2 supplies the generated power to the tag IC 14-1, and the tag IC 14-1 is activated. When the signal included in the radio wave or magnetic field received by the tag antenna 14-2 is a read signal, the activated tag IC 14-1 uses information stored in the tag IC 14-1 corresponding to the read signal as the tag antenna. A reply is placed on the radio wave or magnetic field generated by 14-2. On the other hand, when the signal included in the radio wave or magnetic field received by the tag antenna 14-2 is a write signal, the activated tag IC 14-1 stores information included in the write signal.

Thus, when the tag control unit 43 of the mobile terminal 40 stores information in the tag unit 14 and acquires information from the tag unit 14, power is supplied to the tag unit 14 from the inside of the detection device 10. There is no need. That is, even when the detection device 10 is in the power OFF state or the sleep state, the tag control unit 43 of the portable terminal 40 stores information in the tag unit 14 of the detection device 10 and acquires information from the tag unit 14. be able to.

Further, the tag IC 14-1 activated by the radio wave or magnetic field received by the tag antenna 14-2 outputs an activation signal to the power supply control unit 17, for example. The power supply control unit 17 having received the activation signal supplies the power supplied from the battery 16 by the power supply control unit 17 to, for example, at least the control unit 11. For example, when the control unit 11 to which power is supplied is activated, the detection device 10 is turned on. That is, the detection device 10 is configured to be in a power-on state when information is stored in the tag unit 14 by the tag control unit 43 of the mobile terminal 40. When the power supply of the detection device 10 is in the ON state, the control unit 11 supplies power to the tag IC 14-1 of the tag unit 14 so that information is stored in the tag IC or stored in the tag IC. Information can be acquired.

Furthermore, when the detection device 10 that is in the power ON state is in the power OFF state or in the sleep state, the control unit 11 outputs a stop signal or a sleep signal to the power control unit 17. For example, the power supply control unit 17 that has input the stop signal or the sleep signal stops the supply of power or reduces the amount of power supply to at least the control unit 11. For example, when the supply of power to the control unit 11 is stopped, the detection device 10 is in a power OFF state, and when the amount of power supply to the control unit 11 is reduced, the detection device is in a sleep state.

<< 2. Operation of Plant Equipment Status Collection System >>
<< 2-1. Collecting plant equipment status >>
With reference to FIG. 3A, FIG. 3B, and FIG. 3C, the plant apparatus state collection system 1 demonstrates the example of operation | movement which collects the state of a plant apparatus. Here, the sensor module 10 will be described on the assumption that it is correctly connected to the WSN constructed by the sensor gate module 20.

In step ST101, the sensor module 10 returns from the sleep state by a timer at every set detection interval to be in a power ON state, detects the state of the plant equipment to which the sensor module 10 is attached for the set detection item, The detected value is transmitted to the sensor gate module 20 together with its own sensor ID. That is, the data transmitted in step ST101 is data 101 shown in FIG. 3B. After transmitting the data 101, the sensor module 10 sets a timer and goes to sleep again.

In step ST102, the sensor gate module 20 transmits the received sensor ID and detection value to the cloud server 30 via 3G / LTE together with the network ID of the WSN built by itself. That is, the data transmitted in step ST102 is the data 102 shown in FIG. 3B.

Here, in step ST102, each time the sensor gate module 20 receives a detection value from any of the sensor modules 10 connected to the WSN constructed by itself, the sensor gate module 20 transmits the sensor ID and the detection value together with the network ID. May be. Alternatively, in step ST102, the sensor gate module 20 temporarily stores the received sensor IDs and detection values, and temporarily stores a plurality of sensor IDs and detection values for each set transmission interval. May be transmitted together with the network ID.

In step ST103, the cloud server 30 updates the plant information (data 002) by reflecting the received data 102 in the plant information (data 002) stored in the storage unit 33 of the cloud server 30. Step ST101, step ST102, and step ST103 are repeated as needed.

In the plant equipment state collection system 1, the state of the plant equipment detected by the sensor module 10 is automatically reflected in the plant information (data 002) stored in the cloud server 30. As a result, it is not necessary for the worker in charge to move to the position where the target plant device is arranged every time the state of the plant device is detected or confirmed. Further, as shown in FIG. 3C, the manager in charge connects to the cloud server 30 using, for example, a notebook personal computer 60, and browses the plant information (data 002) stored in the cloud server 30 to remotely access the plant. The state of the device can be monitored. Note that the terminal used by the manager is not limited to the notebook personal computer 60, and any terminal such as a desktop personal computer that can be connected to the cloud server 30 can be used.

<< 2-2. Maintenance work >>
4A, 4B, 4C, 4D, 4E, 4F, 4G, 4H, 4I, 4J, 4K, and 4L with reference to FIG. 4A, FIG. 4D, FIG. An example will be described. The operation when performing the maintenance work is, for example, << 2-1. This is started when a “confirmation required” state (a state where the measured value is out of the standard value range) occurs in the state of the plant equipment collected in “Collecting the state of plant equipment”. For example, as shown in FIG. 3C, the occurrence of the “confirmation required” state in the state of the plant equipment is obtained by browsing the plant information (data 002) stored in the cloud server 30 using the notebook computer 60. Discovered by plant managers. In step ST501, the manager in charge of discovering that the “necessary confirmation” state has occurred in the state of the plant equipment is in an abnormal state due to the difference between the measured value and the standard value or the duration of the state. If it is determined that there is, the state of the plant equipment is updated (“Confirmation required” → “Abnormal”). FIG. 4C shows a display example of the notebook computer 60 when the state of the plant equipment is updated using the notebook computer 60. In the example shown in FIG. 4C, the state of the plant equipment of the sensor module 10 specified by the sensor ID: 0123567 connected to the network ID: 1577 is updated from “confirmation required” to “abnormal”. In step ST502, the manager in charge instructs the worker in charge carrying the tablet terminal 40, for example, repair work or the like by e-mail or written document. In addition, when the state of the plant equipment of a specific sensor module 10 becomes “abnormal” in the plant information (data 002) in the cloud server 30, the cloud server 30 or the sensor gate module 20 notifies the sensor module 10 via the WSN. A start signal may be transmitted to cause the notification unit 15 of the sensor module 10 in which the state of the plant equipment is “abnormal” to perform a notification operation (flashing or voice output).

In step ST503, the worker in charge acquires plant information (data 002) using the tablet terminal 40. FIG. 4D shows an example of the

touch panels

45 and 46 of the tablet terminal 40 when the plant information (data 002) is acquired using the plant application.

In step ST504, the worker in charge selects the sensor module 10 (work target SM) in an abnormal state. In the example shown in FIG. 4D, the worker selects the sensor module 10 specified by the sensor ID: 0123567.

In step ST505, the worker in charge moves through the plant and searches the work target SM by RFID by holding the tablet terminal 40 over the sensor module 10. When the tablet terminal 40 is held over the sensor module 10, a read signal is automatically transmitted to the sensor module 10 by the tag control unit 43 on a radio wave or magnetic field. FIG. 4E shows an example of the

touch panels

45 and 46 of the tablet terminal 40 when the sensor module 10 specified by the sensor ID: 0123567 is selected in the example shown in FIG. 4D. In the example shown in FIG. 4E, “Detected value of sensor 1 is abnormal.” Is displayed, indicating that the detected value of the temperature on the high temperature side which is one of the detection items is abnormal.

In the example shown in FIG. 4E, the mounting information of the sensor module 10 that has detected an abnormal state is displayed. The attachment area of the attachment information shown in the example shown in FIG. 4E is set when the sensor module 10 is attached, for example. Therefore, the person in charge of work can easily recognize the place where the sensor module 10 that has detected the abnormal state is attached.

In the example shown in FIG. 4E, “Please hold your tablet over the target SM” is displayed. In this state, when the worker in charge holds the tablet terminal 40 over the sensor module 10, the tag control unit 43 of the tablet terminal 40 can automatically transmit the read signal on a radio wave or a magnetic field.

In step ST506, the sensor module 10 that has received the radio wave or magnetic field including the read signal returns from the sleep state to the power ON state by the port interrupt. Specifically, first, the tag unit 14 (specifically, the tag IC 14-1) is activated, and the tag unit 14 outputs, for example, an activation signal to the power supply control unit 17. The power supply control unit 17 that has input the activation signal supplies power to at least the control unit 11. If it does so, the control part 11 will start and a sensor module will be in a power ON state.

In step ST507, the control unit 11 of the sensor module 10 acquires the current date and time information from the time measuring unit 18 and stores it in the tag IC 14-1. Thus, the WSN time when the tablet terminal 40 is held over the sensor module 10 is stored in the tag IC 14-1. Note that, as described above, the date and time counted by the timing unit 18 of the sensor module 10 is synchronized with the WSN time, and the processing times of steps ST506 and 507 are assumed to be negligible.

In step ST508, the tag IC 14-1 generates device information (data 508) including the sensor ID and date / time information (WSN time) stored in the tag IC 14-1 in response to the read signal. A reply is made to the tablet terminal 40 in a radio wave or magnetic field. Thereby, the tablet terminal 40 can acquire sensor ID and date information automatically.

In step ST509, after transmitting the device information, the control unit 11 of the sensor module 10 reduces the power supply amount to the power control unit 11 and returns to the sleep state.

In step ST510, the control unit 41 of the tablet terminal 40 determines whether or not the sensor ID of the sensor module 10 selected in step ST502 matches the sensor ID acquired in step ST508 (sensor ID verification). .

If the sensor ID of the sensor module 10 selected in step ST502 does not match the sensor ID acquired in step ST503, for example, in step ST511, the example shown in FIG. , 46 and voice output from the speaker 44 (verification result notification). In the example illustrated in FIG. 4F, it is displayed that the sensor ID of the sensor module 10 selected in step ST502 does not match the sensor ID acquired in step ST508. Similarly, a voice output is made that the sensor ID of the sensor module 10 selected in step ST502 does not match the sensor ID acquired in step ST508 (verification result notification). As a result, the person in charge of the work does not perform work such as repair on the plant equipment to which the sensor module 10 holding the tablet terminal 40 is attached in step ST503. When the example illustrated in FIG. 4F is displayed on the

touch panels

45 and 46 of the tablet terminal 40, the worker in charge acquires the sensor ID of the other sensor module 10 by holding the tablet terminal 40 over the other sensor module 10. The determination in step ST510 is made again.

On the other hand, when the sensor ID of the sensor module 10 selected in step ST502 matches the sensor ID acquired in step ST508, in step ST511, for example, the example shown in FIG. The

touch panel

45 and 46 indicate that they match, and similarly, the speaker 44 outputs a sound indicating that they match (match result notification). When the example shown in FIG. 4F is displayed and output by voice, it can be confirmed that the sensor module 10 over which the worker in charge holds the tablet terminal 40 is the sensor module 10 that has detected the abnormal state. That is, speaker 44 and

touch panels

45 and 46 function as a notification unit that notifies whether or not the sensor ID of sensor module 10 selected in step ST502 matches the sensor ID acquired in step ST508. As a result, the person in charge of the work can easily identify the plant equipment to be worked on and perform maintenance work such as repair, thereby shortening the work time.

Further, when the sensor ID of the sensor module 10 selected in step ST502 matches the sensor ID acquired in step ST508, step ST512 is executed. In step ST512, the control unit 41 of the tablet terminal 40 transmits the date / time information acquired in step ST508 to the timing unit 45 of the tablet terminal 40, and the timing unit 45 counts the date / time in synchronization with the date / time information (WSN time). To do. Thereby, the date and time counted in the tablet terminal 40 is synchronized with the WSN time. In addition, although the processing time of steps ST510 and 511 is assumed to be negligible, the date and time may be corrected in consideration of the processing time.

In step ST513, the person in charge of the work performs maintenance work such as repair of the plant equipment, and when the maintenance is completed, touching “work completion” in the example shown in FIG. 4G proceeds to step ST514. At this time, the tablet terminal 40 stores the date and time (synchronized with the WSN time) of the time measuring unit 45 when “work completion” is touched, that is, the work completion date and time in the storage unit 48 of the tablet terminal 40.

In step ST514, the person in charge of the operation operates the tablet terminal 40 to input the work content (work history input). In the example shown in FIG. 4G, when “work completion” is touched, the example shown in FIG. 4H is displayed on the

touch panels

45 and 46 of the tablet terminal 40. In the example shown in FIG. 4H, the sensor ID, the mounting area, the mounting equipment, the person in charge of the work, and the work completion date and time are displayed. Note that information stored in advance in the storage unit 48 of the tablet terminal 40 is automatically displayed as the information on the person in charge of the work, and the information stored in the storage unit 48 of the tablet terminal 40 is automatically displayed as the work completion date and time. Is displayed. Also, in the example shown in FIG. 4H, the text input field for the contents of maintenance work such as repair of the plant equipment performed by the worker, and the state of the plant equipment after the maintenance work such as repair of the plant equipment is performed. A field to select and enter from the list is displayed. When the worker in charge touches “Register” in the example shown in FIG. 4H after completing these inputs, the process proceeds to step ST515.

In step ST515, the tablet terminal 40 transmits the work content and the plant equipment state input in step ST514 to the cloud server 30 together with the sensor ID, work completion date and time, and information on the person in charge of the work (work history registration, plant equipment state). update). That is, the data transmitted in step ST506 is data 515 shown in FIG. 4B. The work completion date / time information included in the data 515 is the date / time when the “work completion” in the example shown in FIG. 4G is touched (synchronized with the WSN time).

In step ST516, the cloud server 30 reflects the received data 515 in the plant information (data 002) stored in the storage unit 33 of the cloud server 30 (plant information update). Information on the work completion date and time, the person in charge of the work, and the work content included in the received data 515 is stored in the storage unit 33 as a work history corresponding to the sensor ID. After the reflection of the data 515 to the plant information (data 002) is completed in step ST516, when the worker in charge confirms the plant information (data 002), the example shown in FIG. 4I is displayed on the

touch panels

45 and 46 of the tablet terminal 40. Is displayed. In the example shown in FIG. 4I, “repair completed” is displayed in the field of the sensor module 10 identified by the sensor ID: 0123567, which is the sensor module 10 attached to the plant equipment on which the worker in charge performed the repair or the like. Is displayed. In addition, a work history tag is displayed in the vicinity of the “repair completed” display. In the example shown in FIG. 4I, “End of work” for ending the plant application is displayed. Until the “work finished” is touched, the work history data can be displayed by touching the work history tag to display the work history data as in the example shown in FIG. Good. When “end of work” is touched, registration confirmation information is transmitted from the tablet terminal 40 to the cloud server 30. When the cloud server 30 receives the registration confirmation information, the cloud server 30 changes the work history from the correctable state to the uncorrectable state.

In step ST517, for example, after confirming “repair completed” in the example shown in FIG. 4I, the worker in charge reports the completion of the task to the manager in charge by mail or in writing. In step ST581, when the manager in charge who receives the work completion report browses the plant information (data 002) stored in the cloud server 30 using the notebook computer 60, the example shown in FIG. Displayed on the screen. In the example shown in FIG. 4K, “repair completed” is displayed in the column of the sensor module 10 identified by the sensor ID: 0123567, which is the sensor module 10 attached to the plant equipment on which the operator has performed the repair work. Is displayed, and it can be confirmed that the abnormal state that has occurred has been resolved. Moreover, when the completion of maintenance work such as repairs cannot be confirmed, it can be used as evidence for giving guidance to the person in charge of the work, which can contribute to strengthening work monitoring. Further, in the example shown in FIG. 4K, a work history tag is displayed, and when the work history tag is clicked (selected) by a mouse operation, the example shown in FIG. 4L is displayed. In the example shown in FIG. 4L, the work completion date and time, the person in charge of the work, and the work content stored in the cloud server 30 are displayed as the work history. When there are a plurality of work histories, the work histories may be sequentially switched and displayed, or a list of work histories may be displayed.

In the operation when the maintenance work of the plant equipment is performed, the plant equipment state collection system 1 includes the sensor ID of the sensor module 10 selected by the worker and the sensor ID of the sensor module 10 held by the worker in charge of the tablet terminal 40. Are matched, and if they match, the date and time counted by the tablet terminal 40 (the time counting unit 45) is synchronized with the date and time information acquired from the sensor module 10. Then, the sensor ID of the sensor module 10 selected by the operator and the work completion date / time information timed by the tablet terminal 40 (timer 45) are transmitted to the cloud server 30 together with the work content information indicating the work content from the tablet terminal 40. . Therefore, it is not necessary for the person in charge of the work to manually input the sensor ID and the work completion date and time when registering the work content, and the work of inputting information can be simplified and accurate work information can be managed. In particular, since the date and time synchronized with the date and time information in the sensor module 10 is stored in the cloud server 30 as the work completion date and time, more accurate work completion date and time can be accumulated, and the operation tendency of the plant equipment can be accurately grasped. Can contribute to the stabilization of plant operation.
Furthermore, the time counting unit 18 of the sensor module 10 measures the date and time in synchronization with the other sensor modules 10, the sensor gate module 20, the cloud server 30 and / or the repeater 50 via the WSN, so that the tablet terminal 40 also has the WSN. The time can be synchronized and more accurate time management without deviation from the WSN time can be performed.

In the above-described embodiment, the operation when the maintenance work is performed has been described as an example. In addition to the maintenance work, an inspection work or a plant equipment in which the worker in charge periodically checks the state of the plant equipment visually. Steps ST501 to ST518 may also be executed in daily operation work for performing the operation adjustment. In these operations, as in the case of maintenance operations, there is no need for the operator to manually input the sensor ID and the operation completion date and time when registering the operation content, and the operation information can be simplified and accurate operation information can be obtained. Can be managed.

As shown in FIG. 5, the detection apparatus 10 includes a camera 12-1 that captures an image of the plant equipment as the state of the plant equipment. The detection unit 12 includes the image of the plant equipment as data representing the state of the plant equipment. It may be transmitted to the data storage device 30. Hereinafter, the detection device 10 including the camera 12-1 is also referred to as a “camera module 10”. Further, the plant equipment state collection system 1 may include both the sensor module 10 and the camera module 10 that do not include the camera 12-1.

The camera 12-1 includes, for example, an imaging element made of CMOS and a lens that receives light from the outside. The image captured by the image sensor is sent to the control unit 11, and the control unit 11 performs image compression processing (for example, JPEG) and image division processing so that the received image is suitable for transmission through a network connection.

6A and 6B, an example of an operation in which the plant equipment state collection system 1 collects the state of the plant equipment by the camera module 10 will be described.

In step ST111, as in step ST101 of FIG. 3A, the camera module 10 returns from the sleep state by a timer at every set detection interval and enters the power ON state, and is installed in a predetermined range (at least a part of the plant equipment). And the image is transmitted to the sensor gate module 20 together with its own sensor ID and the date and time (imaging date and time) measured by the timer 18. That is, the data transmitted in step ST111 is data 111 shown in FIG. 6B. After transmitting the data 111, the camera module 10 sets a timer and goes to sleep again.

In step ST112, as in step ST102 of FIG. 3A, the sensor gate module 20 transmits the received sensor ID, image, and date and time together with the network ID of the WSN built by itself to the cloud server 30 via 3G / LTE. . That is, the data transmitted in step ST112 is data 112 shown in FIG. 6B.

In step ST113, as in step ST103 of FIG. 3A, the cloud server 30 reflects the received data 112 in the plant information (data 002) stored in the storage unit 33 of the cloud server 30 to generate plant information (data 002). Update. Step ST111, step ST112, and step ST113 are repeated as needed.

Thus, the plant equipment state collection system 1 can include the plant equipment image and the imaging date and time in the plant information by the camera module 10. The manager in charge can connect to the cloud server 30 using, for example, the notebook personal computer 60, and remotely monitor the state of the plant equipment even in the image by browsing the images stored in the cloud server 30 and the imaging date and time. Therefore, the plant can be managed in more detail. Note that the camera module 10 may perform imaging when receiving a shooting start signal from the cloud server 30 in addition to the set detection interval, and the imaging timing is arbitrary.

The present invention can be applied to a plant equipment state collection system. The present invention is particularly applicable to a plant equipment state collection system that accurately manages work information of plant equipment.
