Description

  The present invention relates to a driving device in a multistage multi-row parking device and an abnormality alarm method using the driving device.

  Conventionally, relatively small multistage parking devices installed on the premises of apartment houses (apartments, apartments) generally do not have a dedicated parking lot manager resident on their own, and the contract users themselves operate the vehicle. There are overwhelmingly many things to do. In addition, such parking devices are rarely equipped with an expensive remote monitoring system (such as a remote monitoring system by a maintenance management center via a communication line). Therefore, if an abnormality occurs, how the user recognizes the state of the abnormality and then reports the exact abnormality to the maintenance management center via the user. It greatly affects the speed of work.

  FIG. 9 is a front view showing a conventional operation panel. FIG. 10 is an overall front view illustrating an example of a multistage parking apparatus including the operation panel of FIG. This multistage multi-row parking apparatus 101 is exemplified by a hydraulic three-stage three-row lift pit type. As shown in FIG. 10, in this example, a pallet lifting / lowering body 105 having three pallets of an upper pallet 102, a middle pallet 103, and a lower pallet 104 is moved up and down in the pit 106. The pallet elevating bodies 105 are provided in three rows in the width direction. An operation post 108 is erected on the upper side of the right deck 107 provided on the entry side, and a driver panel 110 is provided on the upper front surface of the operation post 108.

  As shown in FIG. 9, the operation panel 110 includes a power key switch 111 for turning on / off the power, an interlock key switch 112 used for lifting and retreating the pallet lifting body 105, and a pallet lifting body. 105, a selection switch 113 for selecting an operation target row group, a storage pushbutton switch 114 for storing (lowering) the pallet lifting body 105 in the pit 106, and a lifting for raising the pallet lifting body 105 A push button switch 115 and an alarm lamp 116 are provided. In the lower part of the operation panel 110, a telephone number 117 of a contact is described.

  The warning lamp 116 of the operation panel 110 can be operated with the power switch 111 turned on, and lights up when one of the upper, middle and lower pallets on the pallet lifting body in each parking row is outside the boarding position. The light is turned off when the vehicle is in the fixed entry position, and blinks when the control device determines that a failure or abnormality has occurred.

  In the following, an example will be described in which an abnormality occurs when performing loading / unloading with respect to the middle pallet 103 (No. 4) of the pallet lifting body 105 of the right row base 109 shown in FIG.

  First, the user switches the power key switch to “ON”, switches the selection switch 113 to the right row group, and then presses the ascending operation push button switch 115. By continuing to push the ascending operation pushbutton switch 115, the pallet lifting body 105 in the right parking row base starts to rise, and the warning lamp 116 is turned on when leaving the fixed entry position.

  In the middle of this ascent, when a certain abnormality occurs (for example, an abnormal phenomenon in which the limit switch for detecting the fixed position does not detect the fixed position even after a predetermined time elapses), the control device determines this abnormality. Based on this, an emergency stop command is given to the lifting drive source of the pallet lifting body 105 and a blinking command is given to the alarm lamp 116 of the operation panel 110.

  As a result, the pallet lifting body 105 stops moving up and down, and the alarm lamp 116 blinks. The user (operator) recognizes that an abnormality has occurred by visually confirming that the pallet lifting / lowering body 105 has stopped and the flashing of the alarm lamp 116 despite continuing the pushing operation of the raising operation pushbutton switch 115. To do.

  And a user reports to the telephone number 117 (phone number of a maintenance management center etc.) of the contact address described in the operation panel 110 (an operation post etc. are included). Upon receiving this notification, the maintenance management center dispatches maintenance personnel to perform restoration work.

  As a conventional technology of this type, if the sensor that detects the normal position of the vehicle mounting pallet detects an abnormality, the abnormality lamp on the operation panel is turned on and a signal is transmitted to the management company via a public line. There is a remote monitoring system for a multistory parking lot that can give an appropriate instruction to a telephone from a user (see, for example, Patent Document 1).

  In addition, as another conventional technology, a multistage parking device that secures the power supply of the detection device even when an abnormality occurs, and displays an abnormality information code number in the status code display window along with the buzzer of the operation panel when the abnormality occurs (See, for example, Patent Document 2).

Furthermore, as another conventional technique, when an abnormality occurs, the “parking device failure” lamp on the operation panel is turned on, the failure number is displayed on the “failure number” display section, and the failure melody is broadcast by the voice synthesizer. There is a safety transmission device for a mechanical multilevel parking device (see, for example, Patent Document 3).
Japanese Patent Publication No. 8-19779 JP 2003-184341 A No. 7-40618

  However, in the above-described abnormality alarm method, the information transmitted from the user to the maintenance management center is only transmitted to the extent that “the pallet lifting / lowering body in the right parking row suddenly stops while the pallet lifts up and the alarm lamp blinks”. Therefore, the dispatched maintenance staff will have all kinds of tools and parts so as to cope with any abnormal contents.

  In addition, although maintenance personnel arrive at the site and investigate the abnormal situation in detail, it is not always the case that an abnormality has occurred in the parking row where the emergency stop has been stopped. For other parking rows, the pallet lifting body is raised. If you enter the pit, you will be forced to repair and replace the faulty part, which is inefficient, and it may be difficult to carry out the recovery work and take longer than necessary. Therefore, a lot of time and labor are required for dealing with an abnormality.

  The problem in such a multistage multi-row parking apparatus cannot be solved because the above-described Patent Documents 1 to 3 relate to different types of mechanical parking apparatuses.

  Therefore, an object of the present invention is to provide an abnormality alarm method capable of transmitting appropriate information from a user to a maintenance management center when an abnormality occurs in a multistage multi-row parking apparatus, and a driving apparatus including the abnormality alarm method.

As a result, an alarm for the occurrence of an abnormality in response to the occurrence of an abnormality is appropriately emitted by blinking the selection unit, and the subsequent abnormal location (failure location) is easily identified and handled with accurate information from the user. be able to.

  In the abnormality alarm method, the blinking of the selection unit may be a different color for each column base. Thereby, it is possible to easily grasp the column base in which an abnormality has occurred with the blinking color even at night.

  Furthermore, in any one of the abnormality alarm methods, an alarm lamp may be blinked when an abnormality occurs. Thereby, the occurrence of an abnormality can be more easily communicated to the user by the blinking of the abnormality occurrence column group.

  In any one of the abnormality alarm methods, at least one of the selection unit and the alarm lamp may be blinked in a plurality of different blinking patterns according to the contents at the time of occurrence of the abnormality. Thereby, the location where the abnormality has occurred can be grasped more accurately by the blinking pattern.

  Further, in any one of the abnormality alarm methods, the selection unit and the alarm lamp may blink in synchronization. In this way, the user can further easily recognize the occurrence of an abnormality.

  On the other hand, the driving device of the multistage multi-row parking apparatus of the present invention includes any one of the above-described abnormality alarm methods. As a result, in a multi-stage multi-row parking device, etc. where the user needs to cope with the occurrence of an abnormality, accurate abnormality information can be communicated from the user to the maintenance management center, etc. when the abnormality occurs. Repairs can be handled.

  The operation apparatus may further include a control unit that includes an independent selection unit for each of the plurality of column groups, and blinks the selection unit of the column group that is abnormally generated when the abnormality occurs. As a result, it is possible to accurately know the line group in which an abnormality has occurred even at night, and it is possible to perform a more prompt repair.

  The present invention makes it easy for the user to report accurate information when an abnormality occurs in the multistage multi-row parking device by means as described above, and can promptly perform the restoration work by appropriately reporting the occurrence of the abnormality. It becomes possible.

  FIG. 6 is a flowchart of a driving operation in the driving device of the present invention, FIG. 7 is a control flowchart in the driving device of the present invention, and FIG. 8 is a failure / abnormality diagnosis flowchart in the driving device of the present invention. Based on these flowcharts and FIGS. 1 to 4 described above, an example of operation by the driving device 30 will be described below. In the following description, a case will be described in which loading and unloading with respect to the middle pallet 3 (No. 4) of the pallet lifting body 5 of the right parking row base 7 in FIG. 1 is performed. In the following description, the main parts of each flowchart will be described separately.

  (1) First, as shown in FIG. 6, as a flowchart of the driving operation, in the case of warehousing to the upper pallet 2 of the ground entry part, the warehousing can be carried out in the stored state, so the front chain 25 is removed and the warehousing is performed. However, since this time it is loading / unloading to / from the middle pallet 3, “NO” is determined in the determination of “entry to the upper pallet?

  (2) Next, when the user inserts a key into the power key switch 37 of the operation panel 31 and switches to “ON”, the three “illuminated pushbutton switches 42 to 44” are temporarily set in the parking row base selection unit. All lights up.

  (3) Next, pressing (selecting) the right illuminated group “illuminated pushbutton switch 42” immediately below the fourth pallet display of the operation object desired to enter / exit, the other two (left and center rows) “ The illumination type push button switches 43 and 44 "are turned off, and only the" illumination type push button switch 42 "in the right column is kept on.

  (4) Next, by turning the lifting switch 39 to the “upward ▲” side and holding it in that position, the pallet lifting body 5 in the right row base starts to rise, and is in the storage state shown in FIG. When leaving the “in-place position on the upper pallet” (when any of the limit switches LP, RP, HP is turned off first), the alarm lamp 41 is lit.

  (5) When the pallet lifting / lowering body 5 reaches the “entry fixed position on the middle pallet” shown in FIG. 4B (when LP and HP are turned ON), the lifting / lowering automatically stops and an alarm is issued. The lamp 41 is turned off. Since this time it is loading / unloading to / from the middle pallet 3, the determination of “Is the target pallet lower?” Is “NO”.

  (6) The user confirms that the alarm lamp 41 has disappeared and releases the lift switch 39. The lift switch 39 automatically returns to the neutral position by a built-in spring mechanism.

  (7) And a user removes the chain | strand 25 of a front surface and performs the goods receipt or delivery of vehicles with respect to the middle stage pallet 3 (4th).

  (8) After entering / exiting, the user hangs the front chain 25 and then turns the elevator switch 39 of the operation panel 31 to the “retracting” side. As a result, when the pallet lifting / lowering body 5 is lowered and leaves the “entry fixed position on the middle pallet” shown in FIG. 4B (when either LP or HP is turned OFF), the alarm lamp 41 is turned on. To do. When the pallet lifting / lowering body 5 returns to the “entry fixed position on the upper pallet” shown in FIG. 4A (when the limit switches LP, RP, and HP are turned on), the pallet lifting body 5 automatically stops. Both the alarm lamp 41 and the “illuminated pushbutton switch 42” in the right column are extinguished.

  (9) Finally, the user turns the power key switch 37 to “OFF”, removes the key, and completes a series of warehouse operations.

  With reference to FIGS. 7 and 8, an abnormality alarm method when an abnormality occurs during the operation as described above will be described below.

  The control device 32 constantly monitors the operation of the parking device 1 during the above-described series of loading and unloading operations. From the comparison between the received detection information and the above-described error code table (FIG. 5) stored in the memory, for example, In (4), when it is determined that the detection by the limit switch (LP, RP, HP) is abnormal in the automatic stop position, “NO” is determined in the determination of “automatic stop at the fixed position of the boarding portion” shown in FIG. After the judgment is made and “lighting command to alarm lamp” is issued, the failure / abnormality judgment shown in FIG. 8 is performed.

  According to the failure / abnormality determination shown in FIG. 8, “identify error code from failure (abnormality) content” is made. In the above case, it is determined that the abnormality of error code “E02” has occurred in the “right column base” that is the target base Then, a blinking pattern corresponding to the emergency stop command of the pallet lifting body 5 and the error code “E02” for the alarm lamp 41 (see FIG. 5: 0.5 seconds on → 0.5 seconds off → 0.5 seconds on → 1. A blinking command is issued at 5 seconds off for one cycle. In addition, a command for blinking in synchronization with the alarm lamp 41 in the blinking pattern is also given to the illuminated pushbutton switch 42 in the right column group. As a result, the rising of the pallet lifting body 5 in the right row group stops, and the alarm lamp 41 and the illuminated pushbutton switch 42 in the right row group blink in synchronization with the blinking pattern.

  Then, the user recognizes that an abnormality has occurred by such blinking of the lamp, and notifies the telephone number 46 (phone number of the maintenance management center, etc.) of the contact address described on the operation panel 31 or the like. The contact information of the maintenance management center or the like that has received this report depends on the contents of the report, in particular, the blink pattern of the alarm lamp 41 and the illuminated pushbutton switch 42, and the specification of the parking column base 7 by the blinking illuminated pushbutton switch 42. It is possible to select replacement parts such as minimum necessary tools, equipment, limit switches, etc. that maintenance personnel should carry. For example, if the flashing pattern of the alarm lamp 41 corresponds to the error code “E01” (see FIG. 5: 0.5 second lighting → 1.5 second lighting is one cycle), it corresponds to the abnormality. It is known in advance that replacement parts (for example, heavy objects) and special tools must be prepared.

  As a result, the maintenance staff carries tools and equipment suitable for failure (abnormality), goes to the multi-stage multi-row parking device 1, and performs quick maintenance work on the right row base where the alarm lamp 41 is flashing. It can be done efficiently.

  After the maintenance person performs the maintenance work for the failure (abnormality) in this way, when the maintenance person performs the “error reset” work, “YES” is determined by the judgment of “error reset?” In FIG. Then, the flashing command cancellation command is issued to the flashing alarm lamp 41 and the illuminated pushbutton switch 42.

  As a result of the “failure (abnormality) diagnosis” in FIG. 8 performed in “failure / abnormality determination” in (A) shown in FIG. 7, “NO” is determined in the determination of “failure (abnormality)?”. When the diagnosis is made, the process returns to the position (B) shown in FIG.

  According to the driving device 30 of the multi-stage multi-row parking apparatus 1 configured as described above, even if the multi-stage multi-row parking apparatus 1 is not equipped with an expensive remote monitoring system, an alarm lamp is displayed when an abnormality occurs. 41 and the parking row group selection illumination type pushbutton switches 42 to 44, the user recognizes the flashing pattern and reports the flashing pattern to the maintenance management center. Since the contents of the abnormality can be grasped fairly accurately, it is possible to select the minimum necessary parts to be carried by the maintenance staff such as tools and equipment.

  Therefore, the subsequent maintenance staff dispatch and on-site restoration work can be performed quickly. In addition, mutual communication between the user and the maintenance management center allows both parties to share fairly accurate details of the abnormality, so that both the user can understand the degree of abnormality and the amount of recovery (resting time and whether or not the user must be present). Etc.), and the effect of reducing anxiety and giving a sense of security.

  In the above embodiment, the multi-stage multi-row parking apparatus 1 having three stages and three rows has been described as an example. However, the target multi-stage multi-row parking apparatus 1 may be a lift / transverse type or a multi-stage type on the ground. The driving method is not limited to the hydraulic type, but may be another lifting mechanism.

  In the above-described embodiment, the blinking pattern that differs depending on the error code has been described. However, the blinking pattern of the alarm lamp 41 may differ depending on the abnormality occurrence stage of a plurality of pallets. A flashing pattern in this case is also created and stored in the RAM 35 of the control device 32, and the alarm lamp 41 is flashed with a flashing pattern corresponding to the abnormality occurrence stage determined by determining the abnormality occurrence stage in failure / abnormality judgment. What should I do?

  Furthermore, the above-described embodiment shows an example, and various modifications can be made without departing from the gist of the present invention, and the present invention is not limited to the above-described embodiment.

  The driving device according to the present invention is used in a multistage multi-row parking device without an administrator or a remote monitoring system.
