It has the implementation determination apparatus 13 which determines, and the abnormality detection apparatus 14 which detects a worker's abnormality. The mobile phone 1 is switched from the normal mode to the measurement mode by receiving a measurement start command from the work management device 2. Here, the measurement mode is a mode in which the execution determination device 13 and the abnormality detection device 14 operate. The normal mode is a mode in which the execution determination device 13 and the abnormality detection device 14 are stopped.

  Application software that permits access from the work management device 2 is installed in the communication device 12 in advance.

  The acceleration sensor 11 includes a sensor main body 111 and an analysis device 112 to which an output signal of the sensor main body 111 is input. The sensor body 111 includes an acceleration sensor unit that detects acceleration in three axial directions (X direction, Y direction, and Z direction), which are different from each other, and a gyro sensor unit that detects an inclination with respect to a vertical line. Yes. The analysis device 112 receives an output signal from the acceleration sensor unit and an output signal from the gyro sensor unit.

  The storage device 132 stores determination criterion information for each work item and each elevator specification. When the work information is input to the determination device main body 131, the determination device main body 131 acquires determination reference information corresponding to the work item and the hoistway specification from the storage device 132. In addition, the determination apparatus main body 131 compares the information on the change in acceleration detected by the acceleration sensor 11 with the determination reference information acquired from the storage device 132, and the work item corresponding to the work time period is found in the work time period. It is determined whether it has been implemented. The determination apparatus main body 131 transmits a determination result as to whether or not a work item corresponding to the work time period has been implemented to the work management apparatus 2 via the communication apparatus 12.

  Further, the storage device 132 stores a determination reference value used when determining whether or not the worker is operating. The determination device main body 131 determines that the acceleration value detected by the acceleration sensor 11 does not exceed the determination reference value stored in the storage device 132 while a predetermined time elapses from the work start time in the work time zone. It is determined that the operator is not operating. When the determination apparatus main body 131 determines that the worker is not operating, the determination apparatus main body 131 notifies the work management apparatus 2 to that effect via the communication apparatus 12.

  The abnormality detection device 14 includes a detection device main body 141 and a storage device 142 that stores an abnormality reference value used when detecting an abnormality of the worker. The detection device main body 141 compares the acceleration value detected by the acceleration sensor 11 with the abnormality reference value stored in the storage device 142. Further, when the acceleration value detected by the acceleration sensor 11 exceeds the abnormality reference value stored in the storage device 142, the abnormality detection device 14 masks the output signal from the acceleration sensor 11 thereafter for a certain period of time. Further, it is determined whether or not the mobile phone 1 has been operated within the predetermined time. The abnormality detection device 14 determines that an abnormality has occurred in the worker when it is determined that the mobile phone 1 has not been operated within the predetermined time.

Different values are set for the inclination angle and operating speed of the escalator for each specification (for example, 30 degrees, 35 degrees, 15 m / min, 20 m / min, 30 m / min).

  When the work item is work with the escalator stopped, that is, chain tension adjustment and drive roller inspection, the judgment reference information includes information on the change in acceleration when the operator gets on the driving escalator. Information on the change in acceleration when the worker goes up and down the steps of the escalator to be stopped is set.

  Next, the operation of the work management system when determining whether or not a work item has been performed will be described. FIG. 3 is a flowchart showing an operation when the work management system of FIG. 1 determines whether or not a work item is executed. First, the work management device 2 determines whether or not the current time is the work start time in the work time zone (step S101). If the work management apparatus 2 determines in step S101 that the current time is not the work start time, step S101 is repeated.

If the abnormality detection device 14 determines in step S201 that the acceleration sensor 11 has not detected an acceleration exceeding the abnormality reference value, step S201 is repeated.

  On the other hand, if the abnormality detection device 14 determines in step S201 that the acceleration sensor 11 has detected acceleration exceeding the abnormality reference value, the abnormality detection device 14 indicates that the acceleration detected by the acceleration sensor 11 is below the abnormality reference value. It is determined whether or not (step S202). In step S202, when the abnormality detection device 14 determines that the acceleration detected by the acceleration sensor 11 is not below the abnormality reference value, step S202 is repeated.

  On the other hand, when the abnormality detection device 14 determines in step S202 that the acceleration detected by the acceleration sensor 11 has fallen below the abnormality reference value, the abnormality detection device 14 waits for a certain period of time, for example, one minute (step S203).

  Thereafter, the abnormality detection device 14 determines whether or not the operator has operated the mobile phone 1 during standby (step S204). If it is determined in step S204 that the operator has operated the mobile phone 1 during standby, since the acceleration exceeding the abnormal reference value is for operating the mobile phone 1, the detected acceleration is recorded. Is discarded (step S205). On the other hand, if it is determined in step S204 that the operation of the mobile phone 1 has not been performed by the worker during standby, the mobile phone 1 determines that an abnormality of the worker has occurred and detects the abnormality of the worker. The work management device 2 is notified of the fact (step S206). Thereafter, the operation of the work management system ends.
