Description

  The present invention relates to an elevator apparatus, and more particularly to an elevator apparatus having a function of detecting a long-period earthquake.

  The elevator control device that performs seismic control operation includes a receiver that receives earthquake information from a seismometer or an emergency earthquake warning system. When earthquake information is received, for example, it displays earthquake occurrence information on the display and A message prompting the user to refrain from using the elevator is displayed (see Patent Document 1).

  By the way, among the seismometers, seismometers that detect long-period earthquakes are devices that detect vibrations with long-period small accelerations. It is difficult to perform a test by giving a test signal.

  The present invention has been made in view of such problems, and provides an elevator apparatus capable of easily diagnosing a failure of an earthquake detection apparatus provided with an apparatus that senses vibrations of acceleration with a small long cycle. It is.

  In order to solve the above problems, the present invention employs the following means.

In an elevator apparatus comprising an earthquake detection device for detecting a long-period earthquake and an elevator control device for controlling the operation of the elevator based on the detection result of the earthquake detection device, the earthquake detection device has a test input terminal. An acceleration sensor that detects a long-period earthquake, a push button switch that supplies a test input to a test input terminal of the acceleration sensor, and a pseudo acceleration detection signal that the acceleration sensor outputs when the push button switch is pressed And a control device for diagnosing the acceleration sensor, a display device for displaying the diagnosis result, and a housing for housing the earthquake detection device having the display device, and a portion covering the push button switch and the display device of the housing Comprises an openable / closable transparent cover, and the earthquake detection device includes an external input / output circuit for transmitting / receiving diagnostic results to / from the outside. The operating state of the external input and output circuit on or off the original on the display device for displaying an abnormality of the seismic detector.

  Since this invention is provided with the above structure, it can diagnose easily the failure of an earthquake detection apparatus.

It is a figure explaining the elevator apparatus concerning this embodiment. It is a figure explaining the external appearance of an earthquake detection apparatus. It is a figure explaining the self-diagnosis process of an earthquake detection apparatus.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram illustrating an elevator apparatus according to the present embodiment.

  In FIG. 1, 1 is an earthquake detection device that detects long-period earthquakes, 2 is a push button switch that is operated when diagnosing the acceleration sensor 4, and 3 is a control device (microcomputer) that controls the entire earthquake detection device 1, The pseudo acceleration detection signal is received, and arithmetic processing is performed on the received pseudo acceleration detection signal to diagnose the state of the acceleration sensor 4. Reference numeral 4 denotes an acceleration sensor that detects long-period vibration, and generates a pseudo acceleration detection signal (pseudo acceleration detection signal) when receiving a diagnosis command from the control device 3.

Reference numeral 5 denotes an input / output circuit that transmits and receives the diagnosis result of the control device 3 to and from the external system 7. Further, a failure of the earthquake detection device 1 can be detected based on the operation state of the input / output circuit 5. Reference numeral 6 denotes a display unit that displays the diagnosis result of the control device 3 according to the state of the indicator lamp and the like. 7 is an external system connected to the input / output circuit. FIG. 2 is a diagram for explaining the external appearance of the earthquake detection apparatus 1. As shown in FIG. 2, the earthquake detection device 1 is housed in a housing 9, and an openable / closable cover 8 is attached to a portion of the housing 9 where a maintenance person works. At the time of maintenance and inspection of the earthquake detection device, maintenance and inspection can be performed simply by opening the cover portion without opening the housing that houses the main body of the earthquake detection device 1. Also, by making the cover a transparent cover, the state of the earthquake detection device can be confirmed in the state of the indicator light without opening the cover, and whether the device is normal or abnormal at a glance. Judgment can be made. Moreover, since it is not necessary to open and close a cover by using a transparent cover, it is suppressed that dust and dust enter into an apparatus.

  FIG. 3 is a diagram for explaining self-diagnosis processing of the earthquake detection apparatus. First, in step 1, the maintenance staff opens the transparent cover of the push button switch unit for maintenance inspection, and in step 2, presses the push button switch of the push button switch unit. In step 3, the control device (microcomputer) 3 outputs a command signal for causing the acceleration sensor 4 to output a pseudo signal in response to pressing of the push button switch.

  In step 4, the acceleration sensor 4 that has received a command from the control device outputs a pseudo acceleration signal to the control device 3. The control device 3 monitors the presence or absence of the pseudo acceleration signal. If the pseudo acceleration signal can be detected, the control device 3 proceeds to step 5; In step S8, the display lamp is driven to a state different from that in step 7. That is, since this state is a state in which no pseudo acceleration signal is generated from the acceleration sensor, an abnormality of the apparatus is displayed.

  In step 5, the control device 3 performs an operation on the detected pseudo acceleration signal, and detects a signal equivalent to a signal detected when a long-period earthquake is detected. The detected signal is output to the input / output circuit 5 connected to the external system 7.

  In step 6, it is confirmed from the signal output in step 5 whether the input / output circuit 5 is operating normally.

  If it is determined in step 6 that the input / output circuit 5 is operating normally, a specific indicator lamp is set in step S7. When it is determined in step 6 that the input / output circuit 5 is not operating normally, the display lamp is driven to a state different from that in step 7.

  In this way, it is possible to determine whether or not the earthquake detection device that detects a long-period earthquake has failed according to the state of the indicator lamp.
