Description

  The present invention relates to an elevator maintenance management apparatus that manages measurement of equipment of an elevator.

  Conventionally, maintenance personnel for elevators perform measurement using a measuring instrument or the like for inspection of elevator equipment such as a control panel (see, for example, Patent Document 1).

Maintenance personnel, when measuring the voltage and current of hoistway equipment, use a measuring device such as a tester to visually check the voltage value and current value, and then perform input operations using a portable communication terminal device. Measurement results are recorded by writing on paper.

FIG. 5 is a flowchart showing an example of the processing operation of the elevator maintenance management system in the embodiment of the present invention.
First, when the time measuring unit 14 of the RFID writer 1 measures that a predetermined time, for example, 24 hours has elapsed (step S1), the measured value acquiring unit 15 determines the voltmeter of the connected elevator control panel. And the measured value by an ammeter is acquired (step S2).

And the writing process part 17 reads the information of the installation building name and elevator number which are memorize | stored in the installation location information storage part 13 of the memory | storage device 12 (step S3).
The write processing unit 17 combines the read information and the measurement value information acquired by the measurement value acquisition unit, and transmits the information to the IC tag 2 via the communication interface 16 and the antenna 20. (Step S4).

  When the maintenance person brings the RFID reader 3 close to the IC tag 2 (YES in step S5), the installed building name, elevator name, and various measurement values stored in the internal memory of the IC tag 2 are stored in the internal antenna. Is transmitted to the RFID reader 3 via.

  When the reading processing unit 33 of the RFID reader 3 receives the transmitted information via the antenna 37 and the communication interface 35, that is, when the RFID reader 3 reads the information stored in the IC tag 2 (step S4), The communication processing unit 34 transmits the read information to the mobile communication terminal device 4 via the communication interface 35 and the antenna 37 (step S7).

When the communication interface 46 of the mobile communication terminal device 4 receives information from the RFID reader 3 via the antenna 49 (step S8), the control unit 41 stores the received information in the measurement information storage unit 43 of the storage device 42. To be recorded in the measurement result table (step S9).
FIG. 6 is a diagram showing a configuration example of a measurement result table stored in the storage device of the portable communication terminal device of the elevator maintenance management system in the embodiment of the present invention in a table format.

  And the discrimination | determination processing part 47 reads the measured value memorize | stored in the measurement information memory | storage part 43 of the memory | storage device 42, and this measured value is in the predetermined range, that is, whether a measured value is a normal value. Is determined (step S10).

  The discrimination processing unit 47 discriminates that the measurement value is normal if the measurement value is within the above-described range as a result of the discrimination described above, and determines “good” as the discrimination result as the measurement value to be discriminated on the measurement information table. Associate. Further, if the measurement value is not within the above-described range as a result of the determination described above, the determination processing unit 47 determines that the measurement value is abnormal and requires repair, and the determination result is displayed on the measurement information table. Recording is performed in association with the measurement value to be discriminated (step S11).

  As described above, in the elevator maintenance management system according to the embodiment of the present invention, the RFID writer 1 on the premises of the elevator facility acquires the measured values such as the voltage value and the current value of the equipment on the premises, and the IC tag 2 on the side. Write to. If the RFID reader 3 carried by the maintenance staff is brought close to the IC tag 2, information on the measured value is read from the IC tag 2 to the RFID reader 3, and this information is further transmitted to the mobile communication terminal device 4 which is an external device. Sent and saved. Therefore, the maintenance staff can record various measured values in the portable communication terminal device by simply bringing the RFID reader 3 close to the IC tag 2 on the RFID writer 1 side. That is, since it is not necessary to visually check the measured value by maintenance personnel, not only the efficiency of the inspection work is improved, but also a mistake in confirming the measured value by visual observation can be prevented. In addition, since manual operation for recording measurement values by maintenance personnel is not necessary, human error related to recording of measurement values can be prevented. Therefore, the measured value can be recorded correctly.

  In the embodiment described above, the RFID writer 1 has been described to acquire various measurement values every time a predetermined time elapses and write information on the measurement values to the IC tag 2. The acquired measurement value information is accumulated and stored in the storage device 12 of the RFID writer 1, and the maintenance personnel who have arrived at the site operate the write button of the input device 18 to store and store the measurement information stored in the storage device 12. Value information may be written to the IC tag 2.

  Further, as a modification, when a maintenance worker performs inspection work or part replacement work other than on-site measurement, the maintenance person operates the input device 44 of the mobile communication terminal device 4 to check the inspection execution date and the parts. An exchange date or the like is input, and the input information is transmitted to the RFID writer 1. After the information is received by the RFID writer 1, the IC tag 2 is subjected to a predetermined operation on the input device 18 of the RFID writer 1. A writing configuration may be used. As a result, a maintenance staff who arrives at the same site at a later date due to a failure or the like can quickly confirm the status of various inspections and parts replacement dates at the site.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be omitted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
