In addition, the operation history can be easily confirmed at each inspection location.

  This makes it possible to utilize useful information at the inspection location at the inspection location without installing an information communication facility for server access, and the work can be performed more accurately.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of a maintenance management support system for a water treatment facility according to the present embodiment.

  The maintenance management support apparatus 100 is used when a cyclic inspection is performed on a device 10n from a plurality of devices 10a installed in the water treatment facility 1. Although this system functions alone, it can be used as a subsystem of a facility management system 600 that handles all facility management operations other than inspection operations.

  The water treatment facility 1 corresponds to a water purification plant, a sewage treatment plant, and a wastewater treatment facility of a business site. The device 10 is a pump, a blower, various measuring instruments, a control device, an indicating instrument, a water treatment machine, a facility structure, or the like.

Main components of the maintenance work support apparatus 100 are via an electronic tag read / write unit 200 and an electronic tag read / write unit 200 that can read and write information of an electronic tag 5 such as an IC tag provided in the device 10. The electronic tag information management means 300 for managing information of the electronic tag 5 to be read and written, the guidance means 400 for guiding the countermeasure method, the maintenance management database 500 for storing equipment inspection information and the like. The maintenance management support device 100 is used on a portable terminal such as a PDA carried during a patrol check or a small PC (Personal
Computer).

  The inspector obtains inspection information of the equipment 10 in the water treatment facility 1 by using the PDA installed in the maintenance management support apparatus 100 during the cyclic inspection. The inspection information is acquired by reading information recorded on the electronic tag 5 such as an IC tag attached to the device 10 by the electronic tag read / write unit 200 and acquiring the identification number of the device 10. Based on the acquired identification number, the electronic tag information management means 300 displays an inspection information input screen for the corresponding device.

  Equipment inspection information input by the inspector, that is, instruction values, visual observation information, and the like are stored in the maintenance management database 500. The inspector determines whether or not the current device state deviates from the normal management reference range based on the device inspection information. If it deviates from the management standard, the countermeasure means is displayed as guidance from the guidance means 400, and the electronic tag read / write means 200 electronically displays the inspection history information, that is, the inspector, the inspection date and time, the type of equipment failure, etc. Write to tag 5.

The facility management system 600 includes a facility management master database 610 and maintenance management means 620. When linking with the facility management system 600, information in the maintenance management database 500 is output to the facility management master database 610 as appropriate, and a plan for maintenance, repair, repair, update, etc. of the device 10 is formulated by the maintenance management means 620. You can also.

  FIG. 2 is a diagram showing the configuration of the electronic tag read / write means 200. The main components of the electronic tag read / write means 200 are a circuit board 220, an antenna board 240, and an interface 260. The circuit board 220 is hardware for performing signal transmission / reception processing with the electronic tag 5. The antenna board 240 transmits and receives signals processed by the circuit board 220 to and from the antenna 9 built in the electronic tag 5.

  The interface 260 connects the electronic tag read / write unit 200 to a portable terminal such as a PDA, and communicates information with the electronic tag information management unit 300. Specifically, it is realized by a device that complies with CF (Compact Flash) and USB (Universal Serial Bus) which are standards for information devices.

  The IC chip of the electronic tag 5 includes a storage unit 6 that stores information communicated with the electronic tag read / write unit 200, and a transmission unit 7 and a reception unit 8 that transmit and receive signals via the antenna 9. Since the electronic tag 5 is affixed to the equipment 10 dispersed in the water treatment facility 1, it is desirable that the electronic tag 5 has no power source and has a specification that can withstand the usage environment in a water purification plant or a sewage treatment plant.

  Next, the operation of the electronic tag read / write means 200 will be described using the flowchart shown in FIG.

In the electronic tag identification number read in step 280, the identification number of the electronic tag 5 attached to the device 10 to be inspected is read. Since the communicable distance varies depending on the specifications of the electronic tag 5 such as the frequency and the antenna size, the portable terminal such as the PDA in which the electronic tag read / write means 200 is mounted to the electronic tag 5 up to the communicable distance in step 280 Move the camera close or hold it. As the frequency, a short wavelength of 13.56 MHz, a microwave band of 2.45 GHz, a UHF band of 950 MHz, or the like can be used.

  As the identification number, a unique number that is not duplicated in each electronic tag 5 is given. The maintenance management database 500 stores a correspondence table between the identification numbers and the devices 10, and information related to the devices 10 can be referred to via the electronic tag information management unit 300 based on the identification numbers.

  In the write trigger reading of step 282, the electronic tag information management means 300 uses the electronic tag information management means 300 to determine whether or not to write the current inspection information of the device 10 into the electronic tag 5, that is, a trigger for whether or not to write (hereinafter referred to as a light trigger). Is read. In the trigger determination of step 284, it is determined whether or not a write trigger is applied. If writing to the electronic tag 5 is unnecessary, the operation of the electronic tag read / write means 200 is terminated. This trigger will be described later.

  If it is determined that the light trigger is applied, the history information reading in step 286 is executed. In step 286, inspection history information related to the inspection target device 10 is read from the maintenance management database 500 via the electronic tag information management means 300. Here, the operation history information can include information such as the instructed value of the device and the cumulative number of inspections in addition to the inspector, the inspection date and time, and the type of device failure described above.

  In the history information write in step 288, the read inspection history information is transmitted to the electronic tag 5 by reading the history information in step 286, and written (written) to the storage unit 6 of the electronic tag 5 via the antenna 9.

  By a series of operations of the electronic tag read / write means 200 described above, inspection history information is stored in the electronic tag 5 when a necessary trigger is applied to the device 10 currently inspected. be able to.

  Next, the operation of the electronic tag information management means 300 will be described using the flowchart of FIG. The electronic tag information management means 300 has a function of controlling the exchange of information between the components of the maintenance work support apparatus 100 and the timing thereof, and stores information from the electronic tag read / write means 200 in the maintenance management database 500. Conversely, control is performed to output information to the electronic tag read / write means 200. Further, the input information from the guidance unit 400 is stored in the maintenance management database 500, and guidance information related to the device 10 stored in the maintenance management database 500 is output to the guidance unit 400.

  In the inspection information input at step 310, the inspection information of the device 10 input by the inspector by the guidance means 400 is read. In the management standard reading in step 320, the management standard for the device 10 for which inspection information has been input in step 310 is read from the maintenance management database 500. The management standard refers to a threshold value or a range of data for confirming that the current state of the device 10 is in a normal state that does not interfere with the operation of the water treatment facility 1.

  Here, the fact that the operation is not hindered means that the quality of the treated water in the water treatment facility 1 is not affected more than a predetermined amount. For example, taking a flocculant injection pump in a water purification plant as an example, the failure of the flocculant injection pump greatly affects the flocculation process, which is one of the most important unit processes in water purification treatment. If the appropriate flocculant is not injected into the raw water turbidity, turbidity aggregation and floc formation will be insufficient, which will not only increase the load on the next filtration process, but will also deteriorate the quality of the treated water. There is also a possibility of inviting.

  As data items indicating the state of the flocculant pump, the housing temperature, the number of revolutions, the vibration level, the visual observation result (the presence or absence of visible damage), and the like are used. For example, the housing temperature is set to A ° C. or lower, and the rotation speed is set within B to Crpm. For rational setting of management standards, it is desirable to apply a hazard analysis method for the treated water quality of the water treatment facility 1.

For example, HACCP (Hazard Analysis and Critical
Control Point), that is, hazard analysis and application of critical control points, comprehensively extract the hazards to the treated water quality derived from the equipment 10, determine whether it becomes an important control point, etc., then check history information Management criteria can be set statistically or analytically based on

  In the standard deviation determination in step 330, it is determined whether or not the above management standard is deviated. If there is a deviation, the write trigger is output to the electronic tag read / write means 200 in the write trigger output in step 340. . In the inspection information writing in step 350, the inspection information read in the inspection information input in step 310 is written in the maintenance management database 500, and the process ends.

  By using the electronic tag information management means 300 as in the present embodiment, the inspection history information is written on the electronic tag 5 side of the device 10 when there is an influence on the treated water quality of the water treatment facility 1. It can be memorized. As described above, in the present embodiment, since information is stored on the electronic tag 5 side, information can be read even with a PDA different from the one when the information is stored, and an information communication facility is not installed. Thus, inspection history information can be retrieved, and more accurate maintenance inspection work can be performed.

  FIG. 5 shows a screen display example of the guidance means 400 of this embodiment. The guidance unit 400 exemplifies the PDA display device shown in FIG. 5 by the processing in the electronic tag information management unit 300 based on the identification number read from the electronic tag 5 of the device 10 by the electronic tag read / write unit 200. A screen like this is displayed. The screen configuration includes an identification number 20 of the device 10, an area name 21 where the device 10 is installed, a name 22 of the device 10, an inspection data input box 23 (also referred to as a prompt 23), and a trend area of inspection data history. 24, an operation history guidance area 25, and the like are displayed. When the device 10 deviates from the management standard, countermeasure guidance for this is displayed.

  FIG. 6 shows a file configuration example of the maintenance management database 500. The device information data file 510 includes a correspondence table between the device 10 to be inspected and the identification number of the attached electronic tag 5, as well as information on the model, date of manufacture, date of introduction, and specifications of the device 10. The management standard data file 520 stores management standards for the device 10.

The guidance data file 530 stores guidance information related to the device 10 to be displayed by the guidance unit 400, for example, information related to a countermeasure method at the time of failure. The inspection history data file 540 stores the inspection history of the device 10. These data file groups are used not only by the electronic tag information management means 300 but also by the electronic tag read / write means 200 and the guidance means 400. Although FIG. 6 shows the minimum necessary data file types, other necessary data files may be appropriately prepared according to the business characteristics of each water treatment facility 1.

  According to this embodiment, not only the identification information from the electronic tag 5 attached to each inspection target device 10 is read, but also the inspection information and the like are written on the electronic tag 5 side and utilized, so that the information server and the like can be used. Even without communication, the operation history can be easily confirmed at each inspection location. This makes it possible to utilize useful information at the inspection location at the inspection location without installing an information communication facility for server access, and the work can be performed more accurately.

  The maintenance management support system of the present embodiment not only reads the identification information from the electronic tag attached to each inspection target device, but also writes out the inspection information etc. on the electronic tag side and uses it to Even without communication, the operation history can be easily confirmed at each inspection location. This makes it possible to utilize useful information at the inspection location at the inspection location without installing an information communication facility for server access, and the work can be performed more accurately.
