  In systems such as Patent Document 1, it is necessary to recognize the location of equipment, and maintenance personnel approach the equipment and use the equipment identifier (from the wireless communication unit or the one attached to the equipment to be inspected, such as RFID). In order to acquire information, it was necessary to specify the location of the information acquisition means. The invention disclosed in Patent Document 2 is also configured so as to be accurate based on the traveling route information and the like. However, the operator is also searched for reading the identifier (from the barcode) attached to the device. There was a burden, and a device to further facilitate the inspection work was desired.

  In the invention of the present application, information such as patrol is not particularly necessary, and the inspection operator reads the identification information from the equipment so that the equipment identification information can be automatically and passively captured just by approaching a certain range of the equipment. It is an object to simplify inspection work by reducing the weight.

The invention of the present application is a beacon tag that is provided in the facility device and constantly transmits identification information of the facility device, a portable terminal that receives a beacon signal from the beacon tag and checks the facility device,
A server that communicates with this portable terminal to manage the inspection database;
In equipment inspection system consisting of
When the portable terminal receives the identification information by approaching the beacon tag,
Activating an inspection program for the equipment and prompting the operator to perform an inspection work, and uploading the input from the operator or the inspection work result created by taking the equipment information in a predetermined procedure to the server Equipment inspection system. It is.

  According to the present invention, it is no longer necessary to search for equipment in a harsh field machine room such as a dark place or a narrow place, and to take in the identification information of the equipment using a terminal for inspection, and it is easy even in such a field environment. There is an effect that the portable terminal can take the identification information and perform the inspection work. In addition, the use of the latest IT has the effect that various applications can be used.

(1) Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 is a diagram showing an overall configuration of an equipment inspection system according to this embodiment, and 1 is equipment equipment to be inspected. Reference numeral 10 denotes a beacon tag that is attached to the device and transmits device identification information. Information including an identifier representing a facility name is called identification information. On the other hand, 20 is a portable terminal for an operator who performs maintenance. Reference numeral 30 denotes a server (system) located at the upper level. The server 30 includes a management server and a database server including a large-capacity storage medium. The server 30 includes, for example, cloud computing.

  The beacon communication 11 transmitted from the beacon tag 10 is a signal that keeps sending device identification information at regular intervals. For example, if the technology of iBeacon (registered trademark), which is a technology standard in the smartphone world, is used, a wireless signal conforming to Bluetooth Low Energy (BLE: registered trademark) is obtained. This is useful because it can fly a distance of several tens of meters indoors. On the other hand, the network communication 31 between the portable terminal 20 and the server 30 is a Wi-Fi (registered trademark) or other network, regardless of whether it is wired or wireless, via a gateway (GW) through a local or wide area network. Anything can be connected.

  The portable terminal 20 is a computer device and is implemented by a tablet terminal, a smartphone, or the like. The internal configuration includes a CPU 22, a memory 23, a beacon receiving unit 21, a network communication unit 24, and a display operation unit 25. The memory 23 stores the inspection information related to the equipment that is exchanged between the beacon tag 10 and the server 30. It consists of information such as equipment specifications, inspection methods, and measurement data.

  Next, FIG. 2 shows a display operation function image of the portable terminal 20. Reference numeral 25-a denotes a display, which is a thin liquid crystal display. The input unit 25-b has a touch panel function or the like, and a button or the like appears as appropriate. Of course, numeric keypad input is also possible. Such an application screen 25-c pops up on the display 25-a. Push-type information is presented by the display operation unit 25 using beacon communication as a trigger. In this example, the equipment device pump No. This is a dialog prompting an inspection operation at the timing when a beacon from 1001 is received. In this case, the identifier is “Pump1001”.

(2) Next, the operation flow of the equipment inspection system will be described with reference to FIG.
In the transition flow shown in FIG. 3, the beacon tag 10 continues to transmit device identification information (ID) by beacon communication from the start (step S10 in the figure, hereinafter referred to as Sn) (S11).

  The portable terminal 20 internally initializes at the start (S20), and then requests the server 30 for information related to the current inspection work instruction (S21). The server 30 organizes work instruction information (S31) and downloads it to the portable terminal 20 via network communication (S32).

  Now, the portable terminal 20 ready for work walks through the site (S22). This may be a random walk-through, or the tour may be made according to a defined route, or it may be urgently taken to a certain place.

And when it comes near the site equipment, the beacon communication from the beacon tag 10 is received (S12). With this reception operation, a dialog as illustrated in FIG. 2 appears and the inspection process is started (S23).

  And input operation concerning inspection data is performed by operation of portable terminal 20 (S24). Note that if there is a separate measurement sensor communication device (not shown) equipped in the equipment 1, measurement data may be taken from there. The inspection results are stored in the memory, and when the inspection work is completed, the inspection results are uploaded to the server 30 (S25).

  The inspection result is sent from the portable terminal 20 to the server 30 via network communication (S26). Receiving it, the server 30 transmits it to the accompanying database server, and the inspection result database is updated (S32). Thereafter, it is used for equipment diagnosis functions such as history management in the server 30 and life analysis.

(3) As another example, an application example is shown by a transition flow (FIG. 4). Here, the download function of the server 30 to the original portable terminal 20 is not executed. After coming through a walk-through near the on-site equipment (S22), a beacon communication is received from the beacon tag 10 (S12), and a dialog as illustrated in FIG. Until the activation (S23), it is not different from the previous example.

Then, the difference will be described. Client / server (C / S) processing is sequentially performed with the portable terminal 20 as the client and the server 30 (S24 and S31). A plurality of times are repeated in S21 and S32.
For example, if the identification information of the device is notified from the client, an inspection operation instruction may be received from the server, and a screen display program (html) for that purpose may be received. Then, if a check input operation (S24) is performed on the client by the client, the server is notified one by one. Then, when all the client operations are completed, the inspection operation is completed and the server 30 is informed (S25). In response to this completion instruction, the database is updated in the server 30 (S32). If a Web server is prepared in the server 30, it becomes easy to construct a more interactive function with the portable terminal 20.

  In addition, design changes using various software resources may be possible. However, since the feature of the present invention is the beacon tag, further reference is omitted.

  The equipment inspection system using the beacon of the present invention can be applied not only to buildings and plants, but also to other industrial fields or commercial facilities.
