Monitor the driving situation. The control unit 20 associates the operation status of each water treatment unit 23 with the identification information, and periodically notifies the management device 1 via the network such as the Internet by the communication unit 22. Moreover, the control part 20 notifies the management apparatus 1 promptly, when an error generate | occur | produces in a water treatment unit.

  The management device 1 has a CPU (Central Processing Unit) 10 as a control unit that controls the operation of the management device 1 in an integrated manner. The CPU 10 is based on an OS (Operating System) program, and executes middleware, application programs, and the like. A storage unit 11, a communication unit 12, a display unit 13, an input unit 14, and the like are connected to the CPU 10 via a bus.

  The storage unit 11 includes a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk device, and the like. Various programs are stored in the ROM, and each function of the management apparatus 1 is realized by the CPU 10 executing various processes according to these programs. The RAM is used as a work memory for temporarily storing data when the CPU 10 executes processing based on a program.

  The hard disk device includes customer information regarding customers who have installed the water treatment facility 2, operation status data indicating the operation status of the water treatment unit, worker information in which skills and experiences of dispatchable workers are registered, and each worker The schedule information in which the schedule is registered is stored.

  FIG. 3 shows an example of the data structure of customer information. In the customer information, the customer's location, the water treatment equipment installed, the water treatment unit constituting the equipment, necessity of entrance education, maintenance history, etc. are registered.

  FIG. 4 shows an example of the data structure of the worker information. In the worker information, information such as worker dispatchable area, possession qualifications, education attendance history, and other work levels that can be handled for each water treatment facility and each water treatment unit are registered.

  FIG. 5 shows an example of the work level. Simple work such as sampling and chemical replenishment is set at a low work level, and advanced work such as trial operation and troubleshooting including cause investigation is set at a high work level. In the example illustrated in FIG. 4, the worker a indicates that the water treatment unit A can handle all operations and the water treatment unit B can handle operations up to cleaning. Similarly, the work levels that can be handled by the entire water treatment facility are determined based on FIG.

  The communication unit 12 communicates with the communication unit 22 of the water treatment facility 2 via the Internet or the like.

  The display unit 13 is a liquid crystal display, for example, and displays various screens. The input unit 14 receives various operations from the administrator, and is a keyboard, a mouse, or the like.

  As the CPU 10 executes the management program stored in the storage unit 11, as illustrated in FIG. 6, a work selection unit 15, a worker selection unit 16, and an update unit 17 are realized. Although not shown, various operations can be performed by accessing the management apparatus 1 via the Internet or the like from an external terminal such as a terminal installed in a customer factory or an inventory base or a mobile terminal. The processing of each unit will be described with reference to the flowchart shown in FIG.

  When a situation requiring dispatch of a worker occurs in the water treatment facility 2, the work selection unit 15 selects a work performed by the worker (step S1). The situation where the worker needs to be dispatched is, for example, regular maintenance, error notification (alert) from the water treatment facility 2 when the operation status is out of the reference range, and the like. The work selection unit 15 extracts the water treatment facility 2 (water treatment unit 23) requiring maintenance from the maintenance history of the customer information. The work selection unit 15 selects a necessary work when a detection value of a sensor provided in the water treatment facility 2 is out of a predetermined range. In addition, the work selection unit 15 identifies the water treatment facility 2 (water treatment unit 23) that needs the restoration work based on the notification received from the water treatment facility 2 via the communication unit 12.

  The worker selection unit 16 refers to the worker information and selects a worker candidate who can perform the work selected in Step S1 at the customer factory F where the water treatment facility 2 is installed (Step S1). S2). Specifically, the worker selection unit 16 selects a worker who has a skill equal to or higher than the work level of the work selected in step S1 for the water treatment unit to be worked.

  For example, when chemical replenishment is required for the water treatment unit A, a worker having a skill level 2 or higher is selected. Further, for example, when a trial operation is necessary for the water treatment unit B, a worker having a skill of level 9 or higher is selected. Workers are selected in the same way for water treatment facilities.

  In addition, the worker selection unit 16 selects a worker in consideration of whether the location of the customer's factory F is within the worker dispatchable area, the presence / absence of attendance history of the entrance education, and the like.

  The worker selection unit 16 refers to the schedule information, and determines the worker who can be dispatched to the customer's factory F as the dispatch worker first among the selected candidates (steps S3 and S4). The management apparatus 1 may notify the location of the customer's factory F serving as a dispatch destination and the content of work to be performed to a mobile terminal such as a smartphone owned by the determined worker.

  After the work is completed, a work report is input via the input unit 14 (step S5). The updating unit 17 updates the worker information based on the work report and other input contents (step S6). For example, when the work is performed by a plurality of workers and a higher level work can be performed by learning work procedures from other workers, the contents are input. The updating unit 17 updates the work level that can be handled by the worker information.

  As described above, according to the present embodiment, it is possible to quickly dispatch a worker who can perform a work required for restoration or maintenance of the water treatment facility.

  When work is required for multiple water treatment facilities or multiple water treatment units in the water treatment facility 2 installed in the factory F of the customer of the dispatch destination, work for each type of water treatment facility or for each water treatment unit Members may be selected. Since it is preferable that the number of workers to be dispatched is small, workers capable of handling a plurality of water treatment facilities and a plurality of water treatment units may be preferentially selected.

  The worker selection unit 16 may select a worker with the lowest skill among a plurality of worker candidates. This is because a worker with high skill can be dispatched when a situation requiring a high level of work occurs in another water treatment facility 2 after the worker is determined. For example, cleaning (level 5 work) is required for a water treatment unit B of a certain water treatment facility 2, and a worker a having level 5 and a worker d having level 9 are selected as candidates for the water treatment unit B. In this case, worker a is a dispatch worker. After that, if consumables replacement (level 6 work) is required for the water treatment unit B of another water treatment facility 2, the worker d should be dispatched promptly by leaving the worker d. Can do.
