Embodiment 1 FIG.
1 is a block diagram showing an elevator system according to Embodiment 1 of the present invention. In the figure, an elevator system monitors an elevator control panel 1 that controls raising and lowering of a car (not shown) and opening and closing of a car doorway (not shown) by a car door (not shown), and control of the elevator control panel 1. And the monitoring center 4 that the elevator monitoring device 2 reports using the communication line 3. An elevator confinement monitoring device 5 is composed of the elevator control panel 1 and the elevator monitoring device 2. Examples of the communication line 3 include an analog line, a digital line, and a broadband line.

  The elevator control panel 1 includes a trapping fault detection unit 11 that detects a trapping fault of a car and a monitoring device communication unit 12 that performs communication between the elevator monitoring device 2 and the fact that a passenger is trapped in the car. Have.

  The confinement fault detection unit 11 measures the elapsed time from the arrival of the car when the door is closed from the time when the car arrives at the destination floor in response to the car call. The door closed state is a state where the car entrance is closed by the car door. In addition, the confinement fault detection unit 11 stores a predetermined time for detecting the confinement fault of the car. Moreover, the confinement failure detection unit 11 calculates a confinement detection count time T2 that is a time obtained by subtracting the measured elapsed time from the stored predetermined time as needed. The predetermined time used for calculating the confinement detection count time T2 is the time from when the car arrives at the destination floor in response to the car call until the confinement fault is detected, and passengers in the car are provided in the car. It is set as a grace time for contacting the outside using the intercom. In this example, 60 seconds is set as the predetermined time. The predetermined time is not limited to 60 seconds, and other time may be set. Generally, 30 to 60 seconds are set as the predetermined time.

  The confinement fault detection unit 11 detects a car confinement fault when the elapsed time reaches a predetermined time, that is, when the confinement detection count time T2 becomes zero. The elapsed time measured by the confinement failure detection unit 11 becomes zero when the car is opened. Therefore, in this case, the confinement detection count time T2 is a predetermined time. Car door opening means that the car doorway is opened by the movement of the car door.

  The monitoring device communication unit 12 transmits the confinement detection count time T2 calculated by the confinement failure detection unit 11 to the elevator monitoring device 2 as needed. In addition, when the confinement fault detection unit 11 detects a car confinement fault, the monitoring apparatus communication unit 12 transmits a confinement fault signal indicating that a car confinement fault has occurred to the elevator monitoring apparatus 2.

  The elevator monitoring device 2 includes a control panel communication unit 21 that communicates with the elevator control panel 1, a notification start timing calculation unit 22 that calculates timing for starting notification to the monitoring center 4, and a notification start timing calculation unit. The communication control unit 23 that reports to the monitoring center 4 using the communication line 3 at the timing calculated by 22, and the report that is the time from the start to the completion of reporting to the monitoring center 4 using the communication line 3 And a notification processing time storage unit 24 for storing the processing time T1.

  The control panel communication unit 21 receives the confinement detection count time T2 transmitted from the monitoring device communication unit 12, and inputs the received confinement detection count time T2 to the notification start timing calculation unit 22. The control panel communication unit 21 receives the confinement failure signal transmitted from the monitoring device communication unit 12 and inputs the received confinement failure signal to the communication control unit 23.

  The notification from the communication control unit 23 using the communication line 3 to the monitoring center 4 is a notification processing time T1 which is the time from the start of the notification to the completion of the notification depending on the communication speed of the communication line 3 to be used and the connection method. Is different. The notification processing time storage unit 24 stores a plurality of notification processing times T1 corresponding to each of a plurality of types of communication lines 3. The stored notification processing time T1 is set to, for example, 0 seconds for a broadband line, 30 seconds for an analog line, and 10 seconds for a digital line.

The notification start timing calculation unit 22 selects and acquires the notification processing time T1 corresponding to the communication line 3 to be used from the plurality of notification processing times T1 stored in the notification processing time storage unit 24. The notification start timing calculation unit 22 calculates a notification start count time T3 that is a time obtained by subtracting the notification processing time T1 from the confinement detection count time T2 transmitted from the monitoring device communication unit 12. That is, the report start timing calculation unit 22 calculates the report start count time T3 by the following equation (1).
T3 = T2-T1 (1)

  The communication control unit 23 starts reporting to the monitoring center 4 when the reporting start count time T3 calculated by the reporting start timing calculating unit 22 reaches the set time. In this example, a time of -5 seconds is set as the set time. As a result, the communication control unit 23 completes the notification to the monitoring center 4 after a lapse of 5 seconds, which is a fixed time, after the confinement failure detection unit 11 detects the confinement failure of the car. In addition, this fixed time can set arbitrary time by changing the setting time of report start count time T3.

  Next, the operation of the elevator confinement monitoring device 5 will be described. FIG. 2 is a flowchart showing the operation of the elevator confinement monitoring apparatus 5 of FIG. First, the notification start timing calculation unit 22 acquires the notification processing time T1 from the notification processing time storage unit 24 (step S101). Thereafter, the notification start timing calculation unit 22 acquires the confinement detection count time T2 from the confinement failure detection unit 11 (step S102).

  Thereafter, the report start timing calculation unit 22 calculates the report start count time T3 using the above formula (1) (report start timing calculation step) (step S103). Thereafter, the notification start timing calculation unit 22 determines whether or not the calculated notification start count time T3 is −5 seconds or less (step S104). If the notification start timing calculation unit 22 determines that the notification start count time T3 is not −5 seconds or less in step S104, the process returns to step S103.

  On the other hand, when the notification start timing calculation unit 22 determines that the notification start count time T3 is −5 seconds or less in step S104, the communication control unit 23 reports to the monitoring center 4 before the confinement failure is detected. Is started (communication control step) (step S105).

  Thereafter, the report start timing calculation unit 22 calculates the report start count time T3 again using the above formula (1), and determines whether the calculated report start count time T3 is −5 seconds or less. (Step S106). Here, when the door is kept closed, the notification start count time T3 remains -5 seconds or less. On the other hand, when the door is opened, since the confinement detection count time T2 is a predetermined time, that is, 60 seconds, the notification start count time T3 is a value greater than −5 seconds.

  In step S106, when the notification start timing calculation unit 22 determines that the notification start count time T3 is −5 seconds or less, the communication control unit 23 determines whether a confinement failure signal is received from the confinement failure detection unit 11. (Step S107). If the communication control unit 23 determines in step S107 that no confinement failure signal has been received, the process returns to step S106.

  On the other hand, when the communication control unit 23 determines in step S107 that the confinement fault signal has been received, the notification to the monitoring center 4 is completed for a predetermined time, in this example, five seconds after the confinement fault is detected, and the elevator The operation of the confinement monitoring device 5 ends.

  If the report start timing calculation unit 22 determines that the report start count time T3 is not -5 seconds or less in step S106, the communication control unit 23 has completed reporting to the monitoring center 4 because the car is open. The notification is stopped before notification (report cancellation step) (step S108), and the operation of the elevator confinement monitoring device 5 is ended.

  As described above, according to the elevator confinement monitoring device 5 according to the first embodiment of the present invention, when the door closing state continues for a predetermined time from when the car arrives at the destination floor in response to the car call. A trapping fault detection unit 11 that detects a trapping fault of the car, and a notification processing time storage unit 24 that stores in advance a notification processing time T1 that is a time from the start to the completion of notification to the monitoring center 4 using the communication line 3. And the elapsed time from the arrival of the car and the notification processing time T1 to the monitoring center 4 when the trapping fault detector 11 detects a trapping fault of the car and only a predetermined time elapses. A notification start timing calculation unit 22 for calculating a timing for starting a notification to the monitoring center 4 and a timing calculated by the notification start timing calculation unit 22 so that the notification is completed. In timing, since a communication control unit 23 to start notification to the monitoring center 4, the communication control unit 23, before the containment failure is detected, it initiates a notification to the monitoring center 4. As a result, the time from when the confinement failure is detected to when the notification to the monitoring center 4 is completed can be shortened.

  Further, the notification processing time storage unit 24 stores a plurality of notification processing times T1 corresponding to each of a plurality of types of communication lines 3, and the notification start timing calculation unit 22 selects a plurality of notification processing times T1 from the plurality of notification processing times T1. When the notification processing time T1 corresponding to the communication line 3 to be used is selected and the timing for starting the notification to the monitoring center 4 is calculated, the elevator confinement monitoring device 5 is installed in a plurality of buildings with different communication lines 3. The notification processing time T1 corresponding to each communication line 3 can be used. Thereby, the time from when the confinement failure is detected until the monitoring center 4 is notified can be made uniform among a plurality of buildings.

  In addition, the communication control unit 23 starts reporting to the monitoring center 4 and the car is opened before a certain period of time has elapsed since the trapping fault detection unit 11 detects the trapping fault of the car. Since the notification to the monitoring center 4 is stopped, it is possible to prevent the monitoring center 4 from being notified erroneously when the door is opened before the confinement failure is detected.

  Further, according to the elevator confinement monitoring method according to Embodiment 1 of the present invention, when the door is closed for a predetermined time from when the car arrives at the destination floor in response to the car call, the car confinement fault Is an elevator confinement monitoring method for reporting to the monitoring center 4 using the communication line 3, a predetermined time for detecting a confinement failure, an elapsed time since the arrival of the car, and communication Using the notification processing time T1, which is the time from the start to the completion of notification to the monitoring center 4 using the line 3, the notification to the monitoring center 4 is completed when a certain time has elapsed since the detection of the confinement failure. As described above, at the timing calculated by the notification start timing calculating step for calculating the timing for starting the notification to the monitoring center 4 and the notification start timing calculating step, Since a communication control step of starting the report to motor 4, before the containment failure is detected, initiates a notification to the monitoring center 4. As a result, the time from when the confinement failure is detected to when the notification to the monitoring center 4 is completed can be shortened.

  In the first embodiment, the configuration in which the elevator confinement monitoring device 5 includes the elevator control panel 1 and the elevator monitoring device 2 has been described. For example, when the confinement failure detection unit 11 is disposed in the elevator monitoring device 2. The elevator confinement monitoring device 5 may have a configuration including the elevator monitoring device 2 without including the elevator control panel 1.
