When the main rope 17 is driven by the hoisting machine 13, the car 5 and the counterweight 15 are mutually connected. Are lifted up and down in an upside down manner. Further, the car 5 and the counterweight 15 are also connected to each other by a compen- sion rope 19. The control panel 9 has an operation control function for controlling the hoisting machine 13 and thereby controlling the operation of the car 5.

  Next, based on FIG.1 and FIG.2, the structure of the diagnostic driving | operation system of the elevator which concerns on this Embodiment is demonstrated. The elevator diagnostic operation system 21 includes at least a control panel 9, a diagnostic operation dedicated device 23, and diagnostic data detection means 25.

  The diagnostic operation dedicated device 23 is provided separately from the control panel 9. As a specific example, the diagnostic operation dedicated device 23 is placed on the upper portion of the car 5. The diagnostic operation dedicated device 23 is connected to the control panel 9 by a control cable 27 suspended from the hoistway. As a result, the diagnostic operation dedicated device 23 moves up and down integrally with the car 5 while being connected to the control panel 9 fixed to the hoistway 3.

  In the present embodiment, the diagnostic operation dedicated device 23 has functional parts such as a data measurement unit 29, a reference value storage unit 31, and an abnormality determination unit / diagnostic operation instruction unit 33.

  The diagnostic data detection means 25 is connected to the diagnostic operation dedicated device 23 and detects diagnostic data used for diagnosing the presence or absence of an abnormality as will be described later. The diagnostic data includes at least one of sound, image, and acceleration, and the illustrated examples of FIGS. 1 and 2 show an aspect including all of the sound, image, and acceleration.

  The diagnostic data detection means 25 is provided corresponding to the diagnostic data, and the illustrated examples of FIGS. 1 and 2 are shown as a microphone 35, a camera 37, and an acceleration sensor 39. The microphone 35, the camera 37, and the acceleration sensor 39 are provided in the car 5 and are lifted and lowered together with the car 5.

  Further, the diagnostic operation dedicated device 23 is connected to the monitoring center 43 via the line interface 41, and an automatic notification is made to the monitoring center 43 via the line interface 41 when an abnormality is found.

  Next, based on the flowchart of FIG. 3, the operation | movement regarding the diagnostic operation system of the elevator which concerns on this Embodiment is demonstrated. First, as a premise, there is a state where the elevator is stopped due to a disaster such as an earthquake. As step S <b> 1, the abnormality determination unit / diagnostic operation instruction unit 33 of the elevator diagnostic operation system 21 instructs the control panel 9 to start automatic recovery operation.

  As step S2, the control panel 9 performs an automatic diagnosis operation in response to a command from the elevator diagnosis operation system 21. As step S3, the elevator diagnostic operation system 21 collects diagnostic data. Specifically, the data measuring unit 29 of the elevator diagnostic driving system 21 receives the diagnostic data (sound, image, acceleration) from the diagnostic data detecting means 25 and sends the data to the abnormality determining unit / diagnostic driving instruction unit 33. Tell. The abnormality determination unit / diagnostic operation instruction unit 33 also obtains data necessary for the determination, such as an abnormality threshold value stored in advance from the reference value storage unit 31.

  In step S4, the abnormality determination unit / diagnostic operation instruction unit 33 of the elevator diagnostic operation system 21 compares the information from the data measurement unit 29 (diagnosis data detection means 25) with the data from the reference value storage unit 31. By doing so, it is diagnosed whether or not an abnormality is detected.

  If an abnormality is detected as a result of the diagnosis in step S4, the elevator diagnostic operation system 21 stops the diagnosis operation as step S7, and if no abnormality is detected, the diagnosis operation is completed as step S5. To do. Further, after completion of the diagnostic operation, the elevator diagnostic operation system 21 performs automatic recovery, that is, instructs the control panel 9 to start normal operation.

  According to the elevator diagnostic operation system of the present invention described above, the control panel and the diagnostic operation dedicated device are prepared separately, and the control panel has a normal operation control function for controlling the operation of the car. The diagnostic operation dedicated device has an inspection operation function for automatic inspection operation. Therefore, when trying to improve or renew the normal operation control function or inspection operation function, the elevator control device itself is used as before. There is no need to review it, and the inspection operation function can be easily changed. That is, for example, when a new automatic recovery operation function is applied to an existing elevator, a new function program is installed in a limited resource (program remaining capacity) in the existing control panel. In addition, when installing in newly developed elevators, it is necessary to ensure compatibility of signal exchange between normal operation functions and diagnostic contents for automatic rest recovery. Each time there is a problem that a corresponding response is forced. On the other hand, with the elevator diagnostic operation system of the present invention, once the diagnostic operation-dedicated device is developed, it can be handled with small modifications, and new diagnostic contents are added. It is possible to easily cope with the case. Moreover, even when applied to an existing elevator, it can be carried out regardless of the remaining program capacity of the existing control panel.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.

  For example, information provided to the abnormality determination unit of the elevator diagnostic operation system includes, in addition to / in place of the above sound, image, and acceleration, temperature, floor data, motor current value of safety circuit state, scale value, etc. May be included. Further, the diagnostic operation dedicated device may include an earthquake detection function and a remote monitoring function.
