Description

  The present invention relates to an elevator monitoring system, an elevator monitoring device, and a cord seal that transmit and receive information related to elevator maintenance and inspection.

  2. Description of the Related Art Conventionally, workers who maintain and inspect elevators generally visit a plurality of sites in one day and perform maintenance and inspection operations at each site. Maintenance inspection work is scheduled in advance and is usually managed so as to move at predetermined time intervals on a predetermined circuit.

  In order to perform such management, the worker calls the monitoring center at the start of work on the site, and communicates the name, information on the site where the work is to be performed, and the fact that work on the site is to be started. The information on the site where work is performed is, for example, the address of the building where the elevator is installed, the name of the building, and the like. When a plurality of elevators are installed in the premises of this building, information on the elevator number is also transmitted to the monitoring center.

  Then, the operator of the monitoring center records the items to be communicated over the telephone (the name of the operator, the location where the maintenance / inspection work is started, and the start of the maintenance / inspection work).

  Such a transmission procedure and a recording procedure at the monitoring center are also performed at the end of the maintenance / inspection work, and are also performed at the start and end of the maintenance / inspection work at other destinations.

Further, as a technique for grasping the movement of the worker on the monitoring center side as described above, for example, as disclosed in Patent Document 1, a worker carries a GPS receiver, and the current position information obtained by the GPS receiver is obtained. Some are sent to the monitoring center.
JP-A-9-107410

  However, in the management method as described above concerning the maintenance and inspection work, a worker on site must make a telephone call to the monitoring center for each work at each site. The elevator has a function of transmitting a signal including information indicating this, that is, a so-called stop notification signal to the monitoring center side when the operation of the control panel is stopped. The operation stop includes a stop for maintenance and inspection work by an operator and an operation stop due to an elevator equipment abnormality.

  Therefore, when a stop notification signal is received at the monitoring center and there is no telephone contact from the worker to the monitoring center, the operator must check whether the stop signal has been sent for maintenance or inspection work, In order to determine whether it has been transmitted, it is necessary to grasp the schedule of the inspection work of the elevator that is the transmission source of the stop signal.

  Further, in the technique disclosed in Patent Document 1 described above, information on the current position of the worker can be known on the monitoring center side, but the status of the elevator maintenance inspection work at this position can be determined on the monitoring center side. I can't figure it out.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator monitoring system, an elevator monitoring device, and a code seal that can easily obtain information related to the maintenance / inspection work in an elevator subject to maintenance / inspection.

  That is, the elevator monitoring system according to the present invention is a system having a portable communication terminal device and an elevator monitoring device, and the portable communication terminal device is installed at an elevator installation location to be maintained and managed. The two-dimensional code including the information for specifying the location is read, the read two-dimensional code is decoded, the information obtained by decoding is transmitted, and the elevator monitoring device receives the information transmitted by the portable communication terminal device The display control of the received information is performed.

In this personal information database, information on the terminal number of the mobile phone 4, information on the name of the inspection worker who is the owner of the mobile phone 4 corresponding to the terminal number, and information on the affiliation of the owner are associated with each other. . Affiliation includes the department and title of the owner.

  Next, processing operation by the mobile phone 4 in the elevator monitoring system according to the embodiment of the present invention will be described. FIG. 8 is a flowchart showing an example of the processing operation by the mobile phone 4 in the elevator monitoring system according to the embodiment of the present invention.

  First, the inspection worker carries the mobile phone 4 that he / she owns, and then heads to the building where the elevator for maintenance inspection is installed. Here, it is assumed that the elevator car to be inspected for maintenance is the first elevator car 3a (see FIG. 1) that moves up and down the first elevator hoistway 3a of the building 1.

  Before an inspection worker performs maintenance / inspection work on an elevator subject to maintenance / inspection, the operation mode of the mobile phone 4 is changed to a two-dimensional code by operating the input unit 45 of the mobile phone 4 according to a predetermined procedure. Switch to reading mode.

When the operation mode of the cellular phone 4 is the two-dimensional code reading mode, the inspection worker attaches the imaging optical system of the imaging device 47 of the cellular phone 4 to the two-dimensional code seal 33 (see FIG. 2) in the car 3a. When a predetermined operation is performed on the input unit 45, the photographing device 47 inputs a two-dimensional code as a subject.
The control unit 41 of the mobile phone 4 recognizes the pattern of the two-dimensional code input by the photographing device 47 (step S1), and performs a decoding process related to this pattern (step S2).

  By performing this decoding process, the control unit 41 acquires the address of the elevator installation building to which the car 3a belongs and the information of the elevator car, which are indicated by the two-dimensional code printed on the two-dimensional code seal 33. The control unit 41 transmits the acquired information together with the terminal number information of the mobile phone 4 stored in the storage unit 52 to the center terminal 5 (see FIG. 2) via the communication interface 43 (step 2).

  In the center terminal 5, the information transmitted from the mobile phone 4, that is, the information related to the elevator corresponding to the location where the two-dimensional code seal 33 is attached, and the information of the terminal number of the mobile phone 4 of the transmission source are transmitted to the communication interface 53. (Step A1).

  The control unit 51 of the center terminal 5 acquires the information received by the communication interface 53, and among the acquired information, the elevator installation building address information and the elevator number information, and the work information database stored in the storage unit 52 (See FIG. 6). And the information of the combination same as the combination of the elevator installation building address and elevator shown by the information acquired as mentioned above among the information of the combination of the elevator installation building address and the elevator car in the work information database is searched.

  And the control part 51 searches the information of the work status matched with the information of the combination of the elevator installation building address and elevator which were searched in this way on the work information database.

  The retrieved information includes the address of the building where the elevator is installed corresponding to the location where the two-dimensional code seal 33 is printed, on which the two-dimensional code read by the mobile phone 4 that is the transmission source of the received information is printed. Corresponds to the information of Unit No. and work status.

  Further, the control unit 51 of the center terminal 5 collates the information of the terminal number of the mobile phone 4 out of the acquired information with the personal information database (see FIG. 7) stored in the storage unit 52. Thus, the same information as the terminal number information from the mobile phone 4 is retrieved from the terminal number information in the personal information database.

  Then, the control unit 51 searches the terminal owner (inspection worker) name and the information of the terminal owner's affiliation, which are associated with the terminal number thus searched in the personal information database (step A2, A3). The retrieved information corresponds to the name of the owner of the mobile phone 4 that is the transmission source of the received information as described above, and the information of the affiliation of the terminal owner.

The control unit 51 determines whether the work status indicated by the information extracted as described above is “working” or “not working” (step A4).
As a result of this determination, the work status indicated by the information extracted as described above is not “work in progress”, that is, the maintenance and inspection work for the elevator corresponding to the place where the two-dimensional code seal 33 is attached is not currently performed. (NO in step A4), the control unit 51 considers that the maintenance / inspection worker starts the maintenance / inspection work for the corresponding elevator, and among the work status information in the work information database, as described above. The retrieved work status is rewritten to “working” (step A5).

Then, in addition to the message indicating that the inspection work has started (eg, inspection work has started), the control unit 51 searches for the elevator installation building searched using the work information database as described above. The address, elevator information, and the name of the inspection worker and the affiliation location of the inspection worker searched using the personal information database as described above are displayed on the display unit 56 of the center terminal 5. (Step A6).
