DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below.

FIG. 1 is a block diagram showing the configuration of an embodiment of a display device for a multi-storey parking lot according to the present invention.

In FIG. 1, the multi-storey parking lot control unit 14 and the display device 15 are incorporated in the control panel 13. The multi-storey parking lot control unit 14 gives a speed command to each of the inverters 16 and 17 in accordance with the operation of the operation panel 12 so that each inverter 1
6 and 17 are the lifting motor 20 and the fork drive motor 21.
Output to a and 21b. The multi-storey parking lot control unit 14 controls the turning motor 22 and the lifter motor 23. An encoder is attached to each of the motors 20 to 23.

The magnitude of the output of each inverter 16, 17,
The rotation amount and the rotation speed of each of the motors 20 to 23 detected by the encoder are fed back to the multi-storey parking lot control unit 14. Thereby, the multi-storey parking lot control unit 14 controls the speed command or the like given to each of the inverters 16 and 17. Further, these data are transferred to the display device 15.

The transferred data is accumulated and stored in the operation data storage unit 24 of the display device 15 as operation data. However, only the latest data is stored as the latest operation data separately from the cumulative operation data. The stored operation data is read by the display device controller 25, processed, and displayed on the display 26. Further, the life data for each mechanism is stored in the life data storage unit 27 in advance and read by the display device control unit 25. The life data is determined based on the life obtained by the test or the life provided by the component manufacturer.

Next, the contents displayed on the display 26 will be described. 2 to 5 show screens of the display 26.

The accumulated time is displayed on the screen of FIG. Here, the power-on time, the power-on time accumulation, the actual operation time, and the actual operation time accumulation are shown separately. The power-on time is the time since the power was last turned on, the cumulative power-on time is the cumulative time that the power was turned on, and the actual operating time is from the power-on time to the warm-up time, emergency stop time, etc. Is the time excluding, and the cumulative actual operating time is the cumulative time. These times are read from the operation data storage unit 24.

By knowing these times, it is possible to make a rough estimate of when maintenance will be required by comparison with the actual operating results. Also, by comparing the actual operating time with the power-on time, it is possible to confirm whether or not an abnormality has occurred.

FIG. 3 is a menu screen for failure diagnosis, in which one of the operation record ratio, the operation load state, and the maintenance information is selected. The maintenance information displays data on the timing and contents of maintenance performed in the past, and is input by the maintenance operator.

FIG. 4 is an operation result ratio screen, in which the operation results for each mechanism are shown by a ratio. Here, the “ratio” is a ratio of comparing the cumulative operation data and the life data for each mechanism. 100% is the number of times of operation based on the life data, and the number of times of operation of the cumulative operation data with respect to the number of times of life data is shown by a bar graph in percentage. The cumulative operation data is read from the operation data storage unit 24, and the life data is read from the life data storage unit 27, processed by the display device control unit 25, and converted into a bar graph.

For example, if the cumulative number of times of operation reaches 99% of the number of times according to the life data, the maintenance worker can judge that the mechanical portion will be broken down in a short time, and the maintenance work is performed to cause a failure or an accident. It can be prevented.

FIG. 5 is a loading load state screen, showing the load states of the lifting motor 20 and the fork drive motor 21 based on the latest operation data. The load state is diagnosed by the magnitude of the outputs of the inverters 16 and 17 that drive the respective motors. When the diagnosis is performed, the carrier 6 and the slide forks 9, 9 are actually operated to obtain the latest operation data, and the latest operation data is stored in the operation data storage unit 24.

The output of the inverters 16 and 17 is displayed as 1
50% is the highest and 150% output is abnormal. The load of both the carrier 6 and the slide forks 9, 9 increases in the order of the idle movement, the light vehicle transfer, and the heavy vehicle transfer, but the load does not reach 150% even when the heavy vehicle is transferred.
Therefore, when the output shows 150%, each motor,
It can be judged that some abnormality has occurred in the inverter or the transmission mechanism.

[0025] Further, the idle movement, the light vehicle transfer, and the heavy vehicle transfer are respectively tested to diagnose whether the correct load according to the weight is displayed. It is abnormal if it is larger or smaller than the expected load. As a result, it is possible to make a diagnosis without using a special measuring instrument such as a dynamic load meter.

As described above, the display device 1 according to the present embodiment.
5 collects operation data via the multi-storey parking lot control unit 14 and stores it in the operation data storage unit 24, and the display device control unit 25 processes the operation data and displays it on the display 26, so that special measurement is performed. It is possible to easily grasp the operating status without using any equipment, and to perform maintenance work efficiently such as predicting the maintenance time.

The life data is stored in the life data storage unit 27.
It is possible to easily determine the necessity of maintenance by reading from the operation data storage unit 24 and displaying it by comparing with the accumulated operation data read from the operation data storage unit 24.

Furthermore, by displaying the latest operation data, the maintenance worker can actually operate and judge the situation.

The embodiment of the present invention has been described above.
It is needless to say that the present invention is not limited to the above-mentioned embodiments and can be appropriately modified within the scope of the gist of the present invention.

For example, the operation data is each inverter 16,
Although the example is shown in which the data is collected only from the encoders of 17 and the motors 20 to 23, the invention is not limited to this, and may be collected from each switch, sensor or the like.

[0031]

As described above, according to the display device of the multi-storey parking lot according to the invention described in claim 1, the operation data is collected and stored in the operation data storage means, and the operation information display means is operated. Since the data is processed and displayed on the display, it is possible to easily grasp the operation status without using a special measuring device and to efficiently perform maintenance work such as prediction of maintenance time.

According to the display device of the multi-storey parking lot of the second aspect of the present invention, the life data is read from the life data storage means and the operation information compared with the operation data read from the operation data storage means is displayed. This makes it possible to easily determine the necessity of maintenance.

According to the display device of the multi-storey parking lot of the third aspect of the present invention, the latest operation data is processed and the operation information is displayed so that the maintenance worker actually operates to judge the situation. can do.
