Description

  The present invention relates to a three-dimensional parking lot apparatus capable of parking a plurality of vehicles in a three-dimensional manner, for example.

  2. Description of the Related Art Conventionally, a multi-story parking lot apparatus that is provided in the vicinity of a condominium, a building, or the like or in a building and can park a plurality of vehicles in a three-dimensional manner is known (for example, see Patent Document 1).

  FIG. 1 is a diagram illustrating an example of a conventional multilevel parking lot apparatus. According to the figure, the multilevel parking lot apparatus 1 is provided with, for example, a plurality of pallets 2 connected in the vertical direction, and these are provided in a plurality of rows in the horizontal direction. The pallet 2 is one on which the vehicle C is mounted.

  The multi-story parking device 1 is provided with an operation panel 6 operated by an operator, and the operation panel 6 has a driving button (not shown) for moving each pallet 2 up and down. In this multi-story parking device 1, for example, when the vehicle C that the operator wants to board is in the lower stage, the operator presses the driving button, so that the pallet 2 that is connected in the vertical direction is moved in the vertical direction for each row. The pallet 2 on which the vehicle C is mounted moves from the lower position to the upper position (for example, the ground G).

  In this case, the pallet 2 is lifted by driving a drive motor (not shown) only when the operation button is pressed for safety. That is, if the operator releases the operation button while the pallet 2 is moving, the drive motor is stopped and the pallet 2 is stopped.

  Therefore, the operator needs to keep pressing the operation button until the pallet 2 reaches the upper position from the lower position. However, the time required for the pallet 2 to reach the upper position from the lower position may feel relatively long for the operator (for example, it takes about one minute to move from the lower position to the upper position). .) Therefore, raising the pallet 2 may feel very troublesome for the operator.

  In addition, when the pressing portion of the driving button is formed to be relatively small, the operator must press the driving button with only the fingertip of the index finger, for example. You may feel tired.

  Therefore, the operator may use a jig that can keep the operation button pressed by being attached to the operation button in order to save the trouble of continuously pressing the operation button. When such a jig is used, since the operation button is pressed by the jig, the operator does not need to press the operation button. Therefore, the operator can leave the front of the operation panel 6.

  However, the fact that the operator leaves the operation panel 6 originally means that the drive motor operates and the pallet 2 is allowed to move up and down arbitrarily, which is not safe. However, the current situation is that there are not a few operators who leave the front of the operation panel 6 using the above-described jig or the like because the pressing operation is troublesome.

JP 2007-170004 A

  The present invention has been conceived under the circumstances described above, and reliably detects that the operator is actually operating the driving button, for example, the operator leaves the operation panel. It is an object of the present invention to provide a multilevel parking lot apparatus that can prevent such an unsafe state.

A multistory parking lot apparatus provided by the present invention is a multistory parking lot apparatus that has a plurality of pallets that are arranged in parallel in at least the vertical direction and on which a vehicle is mounted. and driving means for moving the detection for detecting the presence or absence of the operator's hand and the pressing input means for outputting a pressure signal only when pressure input, the previous SL pressing input means operate so by the operator A pressing signal is output from the pressing input means by the pressing input by the operator, and the operator actually operates the pressing input means by detecting the operator 's hand by the detecting means. Control means for driving the drive means only when it is detected that the drive means is detected.

  In the multi-story parking apparatus according to the present invention, a control panel having the press input unit on a front surface thereof is provided, and the detection unit is in a state in which an operator located on the front side of the control panel operates the press input unit. It is good to detect.

  In the multi-story parking apparatus according to the present invention, the detecting means may be a human sensor that detects heat generated by an operator.

  In the multi-story parking apparatus according to the present invention, the pressing input means may be a pressing type operation switch having a pressing surface formed in a substantially curved surface.

  According to the present invention, only when a pressing signal is output from the pressing input means (for example, a driving button) and the detection means (for example, a human sensor) detects that the operator is operating the pressing input means, The drive motor is driven to move the pallet. Therefore, for example, even if a jig that can keep pressing the operation button is used, the pallet cannot be moved unless the operator actually operates the operation button. Unsafe conditions such as leaving can be prevented.

It is an arrangement plan of a multistory parking lot apparatus according to the present invention and a conventional configuration. It is a front view of an operation panel. It is a side view of an operation panel. It is a block diagram which shows the electrical structure of a multistory parking lot apparatus. It is a flowchart figure for demonstrating the effect | action in a multistory parking lot apparatus.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

  Since the multi-story parking lot apparatus according to the present invention is substantially the same as the multi-story parking lot apparatus having the conventional configuration shown in FIG. 1 described in the background art section, the following description will be given using FIG. 1 again. The operation panel 6 will be described using the same reference numerals in the following description, but the configuration is different from the operation panel 6 having a conventional configuration.

  The three-dimensional parking lot apparatus 1 according to the present invention is provided, for example, in the vicinity of a condominium or a building or in a building, and parks and stores a plurality of vehicles C. In this multi-story parking lot apparatus 1, two pallets 2 on which a vehicle C can be mounted are provided continuously in the vertical direction. These connected pallets 2 are provided in three rows in the left-right direction. In the multi-story parking lot apparatus 1 shown in FIG. 1, a total of six pallets 2 are provided. In the multi-story parking apparatus 1, the radix of the pallet 2 is not limited to this, and pallets 2 having different radixes may be provided in the vertical direction and the horizontal direction.

  In this multi-story parking garage apparatus 1, a space having a predetermined height and a predetermined width is provided in the basement, and the lower pallet 2 of the pallets 2 connected in the vertical direction is normally accommodated in the underground space, and the lower pallet 2 When the vehicle C mounted on the vehicle is used, the vehicle is moved to the height of the ground G (see the vehicle C on the left side shown in FIG. 1). Therefore, the upper pallet 2 is usually disposed at the same height as the ground G (see the vehicle C on the right side and the center shown in FIG. 1).

  The pallets 2 connected in the vertical direction are connected by a plurality of pillars 3, and these can be integrally moved in the vertical direction by a drive motor (not shown). Therefore, in the multi-story parking lot apparatus 1 shown in FIG. 1, a drive motor is provided for each row, and the pallet 2 moves in the vertical direction independently for each row.

  Between the pallets 2 adjacent in the left-right direction, a passage space 4 having a predetermined width is provided for the user to pass therethrough. Further, at the rear of the passage space 4, first to third control panels 21, 22, and 23 are erected in each row.

  A pole 5 is erected on the ground G on the far left side in front view and on the front side of the pallet 2. An operation panel 6 operated by an operator is provided on the top of the pole 5.

  As shown in FIG. 2, the operation panel 6 has a housing formed in a substantially rectangular parallelepiped shape. Although not shown, the housing is a door whose front is openable and closable. By opening the door, the inside can be visually confirmed during maintenance of the operation panel 6 or the like. On the front surface of the casing of the operation panel 6, switches and the like for operation by the operator are provided.

  More specifically, a display unit 10 is formed on the upper front surface of the operation panel 6. The display unit 10 is configured by, for example, an LED display, and can display 4-digit alphanumeric characters, symbols, characters, and the like. The display unit 10 displays the pallet number set by the operator, or displays an error state when any abnormality occurs.

  A numeric keypad group 11 is provided at the bottom of the display unit 10. The numeric keypad group 11 is mainly used for setting the palette 2 desired by the operator. The numeric keypad group 11 has 0 to 9 numeric buttons 11a, an up / down button 11b for moving the pallet 2 up and down, and a cancel button 11c for canceling the operation input state. A switch group (not shown) is provided on the back side of the numeric keypad group 11 to recognize an input operation by the operator.

  An operation button 12 for moving the pallet 2 up and down is provided below the numeric keypad group 11. As shown in FIG. 3, the operation button 12 has an operation surface formed in a substantially curved shape, and is formed in a size and shape that can be operated satisfactorily with the palm of the operator.

  That is, the operation button 12 is not of a size that is pressed by the surface of the fingertip as in the conventional configuration, and the operation surface is not flat. Therefore, the operator can disperse the force applied to the operation surface of the driving button 12 by applying a palm using a relatively large area to the curved operation surface of the driving button 12. . Therefore, the driving button 12 can be pressed relatively easily with a small force, and no pain or fatigue is felt even if the time for which the driving button 12 is kept pressed is relatively long. Therefore, the troublesomeness of continuously pressing the operation button 12 can be reduced.

  The operation button 12 is a so-called momentary switch, and includes a contact switch 12a (described later) that outputs, for example, a non-voltage contact signal (press signal) only when pressed. As will be described later, the output of the contact switch 12a is output to the main controller 20 described later under an AND condition with the output of the contact switch 15a of the human sensor 15.

  A key switch 13 is provided below the operation button 12. The key switch 13 has an insertion hole 13a into which a predetermined key (not shown) can be inserted. The key switch 13 includes a contact switch 13b (described later) that outputs a no-voltage contact signal. When the key K is inserted into the insertion hole 13a by the operator and rotated, for example, clockwise, the contact switch 13b is turned on, and the operation panel 6 is shifted to a state where operation input is possible.

  A mounting plate 14 having a substantially L shape in cross section is provided above the operation panel 6, and a human sensor 15 is mounted on the mounting plate 14. The human sensor 15 is for detecting an operator who is actually pressing the operation button 12. The human sensor 15 is a sensor that detects a temperature difference or a temperature change from the surroundings caused by, for example, heat (far infrared rays) generated from a person. In the present embodiment, the human sensor 15 is formed so that its detection opening (not shown) is near one end and is directed downward, and the detection range of the human sensor 15 is on the lower side. (See arrow A in FIG. 3).

  Therefore, the human sensor 15 can detect the presence / absence of the operator's hand when the operator stands in front of the operation panel 6 and touches the hand to operate the operation button 12. The human sensor 15 includes a contact switch 15a (described later) that outputs, for example, a non-voltage contact signal when detecting the hand of the operator who is operating the operation button 12. As will be described later, the output of the contact switch 15a is output to the main control unit 20 described later under an AND condition with the output of the contact switch 12a of the operation button 12.

  FIG. 4 is a schematic block diagram showing an electrical configuration of the multistory parking lot apparatus 1.

  In this multilevel parking lot apparatus 1, a control unit (hereinafter referred to as “main control unit”) 20 including a microcomputer is provided on the operation panel 6. The main control unit 20 is connected to first to third control panels 21, 22, and 23. More specifically, the main control unit 20 is connected to first to third auxiliary control units 24, 25, and 26 provided in the control panels 21 to 23 in a daisy chain shape. That is, the main control unit 20 and the plurality of auxiliary control units 24 to 26 are connected so that, for example, one-to-many serial communication conforming to the communication standard of RS485 is possible.

  The main control unit 20 sends various signals generated when operated by the operator on the operation panel 6 to the first to third auxiliary control units 24 to 26. The main control unit 20 sends a signal, for example, that the operation button 12 has been pressed and that the operation button 12 has been released to any of the first to third auxiliary control units 24-26. To do.

  A display unit 10 and a numeric keypad group 11 are connected to the main control unit 20. The main control unit 20 performs data processing based on an operation signal (for example, an operation signal to be raised or lowered) generated by an operation from the numeric keypad group 11, for example, display data to be displayed on the display unit 10 (for example, by an operator). The input pallet 2 number data, operation error data, etc.) are transmitted.

  The main control unit 20 is connected to a series circuit including a contact switch 12 a of the operation button 12 and a contact switch 15 a of the human sensor 15. Only when both the contact switch 12a and the contact switch 15a are turned on, the main controller 20 receives a short circuit signal from the contact switches 12a and 15a.

  In other words, the main control unit 20 detects the operator pressing the human sensor 15, turns on the contact switch 15a, and pushes the operation button 12 by the operator to turn on the contact switch 12a. Only when the driver recognizes that the driving button 12 has been pressed and operated by the operator. And the signal which should drive a drive motor (after-mentioned) is sent with respect to any of auxiliary control parts 24-26.

  In addition, when the main control unit 20 recognizes that the driving button 12 is being pressed and operated, for example, when the operator releases the driving button 12, the contact switch 12a is turned off, and any auxiliary A signal for stopping the drive motor is sent to the control units 24-26.

  A contact switch 13 b of the key switch 13 is connected to the main control unit 20. When the operator inserts a predetermined key K through the insertion hole 13a and rotates it in the clockwise direction, the main control unit 20 receives a short-circuit signal indicating that the contact switch 13b has been turned on, and the operation panel 6 performs an operation input. Transition to a possible state.

  As described above, the first to third control panels 21 to 23 include the first to third auxiliary control units 24 to 26, respectively. The first to third electromagnetic contactors 27, 28, and 29 are connected to the auxiliary control units 24 to 26, respectively. The 1st thru | or 3rd drive motors 30, 31, and 32 are connected to the 1st thru | or 3rd electromagnetic contactors 27-29, respectively. A power supply voltage (for example, AC 220 V) supply line is connected in parallel to the first to third electromagnetic contactors 27 to 29 via an inverting unit 33 for inverting the polarity of the power supply voltage. The reversing unit 33 is connected to the first auxiliary control unit 24.

  Each electromagnetic contactor 27-29 is for supplying or interrupting the power supply voltage to each drive motor 30-32. That is, when each of the first to third auxiliary control units 24 to 26 outputs a signal for turning on each of the electromagnetic contactors 27 to 29, each of the electromagnetic contactors 27 to 29 is turned on. A power supply voltage is supplied to each drive motor 30-32 via each electromagnetic contactor 27-29.

  Although not shown, each of the electromagnetic contactors 27 to 29 is operable when a control power supply (for example, AC 200V) is supplied to the coil. In the present embodiment, the electromagnetic contactors 27 to 29 are turned off by controlling the supply of the control power in accordance with signals from the auxiliary control units 24 to 26, and the control power is supplied as described later. It is turned off by being blocked by a separate hardware configuration.

  The main control unit 20 sends a signal to that effect to the first auxiliary control unit 24 when it is desired to reverse the rotation of the drive motors 30 to 32 that are rotationally driven, that is, when the pallet 2 is to be lowered. In response to this, the first auxiliary control unit 24 sends an inversion signal to the inversion unit 33. As a result, the polarity of the power supply voltage is reversed in the reversing unit 33, the rotation of the drive motors 30 to 32 that are rotationally driven is reversed, and the pallet 2 is lowered.

  As described above, when the main control unit 20 recognizes that the operation button 12 has been genuinely pressed by the operator, the main control unit 20 connects any of the electromagnetic contactors 27 to 29 to any of the auxiliary control units 24 to 26. A drive signal for turning on, that is, a drive signal for driving one of the drive motors 30 to 32 is transmitted.

  For example, when the main control unit 20 drives the first drive motor 30 of the first control panel 21, it sends a signal to that effect to the first auxiliary control unit 24 of the first control panel 21. The first auxiliary control unit 24 turns on the first electromagnetic contactor 27 based on the control signal from the main control unit 20. As a result, the power voltage is supplied to the first drive motor 30 and the first drive motor 30 is rotationally driven. Accordingly, the pallet 2 in the left column rises.

  As described above, in the present embodiment, the main controller 20 and the auxiliary controllers 24 to 26 perform serial communication to turn off the electromagnetic contactors 27 to 29 and stop the motors 30 to 32. However, in order to prevent the motors 30 to 32 from being unable to be stopped when a failure occurs in the serial communication, for example, each hardware configuration is used separately from the serial communication. It is desirable not to turn on the magnetic contactors 27-29.

  Specifically, each of the electromagnetic contactors 27 to 29 can be operated by being supplied with a control power. However, each contact switch 12a, 15a, 13b of the operation button 12, the human sensor 15, and the key switch 13 is provided. Control power is supplied to each of the third electromagnetic contactors 27-29 only when all the are operated. Then, when any one of the contact switches 12a, 15a, 13b is turned off, the supply of control power to each of the electromagnetic contactors 27 to 29 is cut off, and each of the electromagnetic contactors 27 to 29 is not turned on.

  In this way, for example, even if a failure occurs in the serial communication, the motors 30 to 32 can be stopped, for example, by the hardware configuration, so that the electromagnetic contactors 27 to 29 are caused by the communication failure. It is possible to prevent a malfunction such that the vehicle is not turned off and to make the multilevel parking lot apparatus 1 with higher safety.

  Next, the effect | action (motor drive control) in this multistory parking lot apparatus 1 is demonstrated with reference to the flowchart shown in FIG.

  Here, it is assumed that the operation panel 6 is in a state where a predetermined key K is inserted through the key switch 13 by the operator and the key K is rotated clockwise so that the operator can perform an input operation.

  First, the main control unit 20 determines whether or not a desired pallet number has been input via the numeric keypad group 11 by the operator (S1). When a desired pallet number is input by the operator (S1: YES), the main control unit 20 recognizes the input pallet number and displays it on the display unit 10 (S2).

  Next, the main control unit 20 determines whether or not the operation button 12 has been truly pressed by the operator (S3). Here, it is assumed that the operator stands in front of the operation panel 6 and holds his / her palm on the surface of the operation button 12 in order to operate the operation button 12. At this time, the human sensor 15 detects that the operator's hand is about to operate the operation button 12, and thereby turns on the contact switch 15a.

  The operator operates to push the operation button 12 in order to raise the pallet 2 with the number displayed in step S2, and continues that state. At this time, the operation button 12 detects that the operator has pressed the input, and turns on the contact switch 12a.

  As shown in FIG. 4, since the contact switch 15a and the contact switch 12a are connected in series, when both of the contact switches 15a and 12a are turned on, a short circuit signal is input to the main control unit 20. The

  In the present embodiment, the main control unit 20 does not recognize that the operation button 12 has been genuinely pressed by only turning on the contact switch 12a of the operation button 12. Therefore, a signal for driving the drive motor is not sent to the control panel corresponding to the pallet number input in step S1 (S3: NO).

  On the other hand, when the short-circuit signal indicating that both the contact switches 15a and 12a are turned on is input, the main control unit 20 determines that the operation button 12 has been truly pressed by the operator (S3: YES). A drive signal for driving the drive motor is sent to the control panel corresponding to the pallet number input in step S1.

  That is, in this embodiment, the main control unit 20 presses the operation button 12 in a genuine manner only when the contact switch 12a of the operation button 12 is turned on and the contact switch 15a of the human sensor 15 is turned on. The pallet 2 is controlled to move up and down. That is, even if only the operation button 12 is pressed, if the operator's hand is not detected by the human sensor 15, the pallet 2 is not raised or lowered.

  As a result, as described in the conventional configuration, in order to save the operator from continuing to press the driving button 12, when a jig that can continue to press the driving button 12 is used, The feeling sensor 15 does not turn on the contact switch 15a because the hand of the operator who tries to operate the operation button 12 is not detected. Therefore, even if the operation button 12 is pressed using the jig, it is not recognized as a genuine pressing operation. Therefore, the operator cannot use a jig, and can prevent an unsafe state in which the operator leaves the front of the driving button 12, and the three-dimensional parking lot apparatus 1 excellent in safety and reliability can be used. can do.

  For example, when the main control unit 20 sends a signal for driving the first drive motor 30 to the first auxiliary control unit 24 of the first control panel 21, the first auxiliary control unit 24 causes the first electromagnetic contactor 27. To turn on. As a result, the power supply voltage is supplied to the first drive motor 30, the first drive motor 30 is rotationally driven (S4), and the left-side pallet 2 corresponding thereto is raised.

  In this case, if the operator releases the operation button 12 while pressing the operation button 12, the contact switch 12 a of the operation button 12 is turned off, and no short circuit signal is input to the main control unit 20. Therefore, the main control unit 20 sends a signal for stopping the rotation of the first drive motor 30 to the first auxiliary control unit 24. As a result, the first auxiliary control unit 24 turns off the first electromagnetic contactor 27, so that the power supply voltage is not supplied to the first drive motor 30, and the first drive motor 30 is stopped (S5). The pallets 2 in the left column corresponding to the one drive motor 30 are stopped. That is, in this case, the operation button 12 functions as a so-called emergency stop button.

  When the pallet 2 is raised, the main control unit 20 determines whether or not the pallet 2 has reached a predetermined position (S6). When the main control unit 20 determines that the pallet 2 has reached a predetermined position by a signal from a limit switch (not shown) (S6: YES), the main control unit 20 sends a signal for stopping the rotational drive to the drive motor. Thereby, rotation of the said drive motor is stopped (S7) and the raise of the pallet 2 is stopped.

  In step S6, if the main control unit 20 determines that the pallet 2 has not reached the predetermined position (S6: NO), the main control unit 20 returns to step S3 and determines whether or not the operation button 12 has been genuinely pressed by the operator. Is determined.

  As described above, according to the present embodiment, the pallet 2 is operated only when not only the ON operation of the contact switch 12a of the operation button 12 but also the ON operation of the contact switch 15a of the human sensor 15 is input. Therefore, it is possible to reliably detect the pressing operation of the genuine operation button 12 by the operator.

  In the above embodiment, the method for detecting the operation of the operator is not limited to the human sensor 15 shown in the above embodiment. For example, an operation by the operator may be detected by imaging the periphery of the operation panel 6 with a CCD camera and performing image recognition. Moreover, you may detect operation by an operator using an ultrasonic wave. Further, these detection methods may be used in combination.

  Note that whether or not the operator is standing in front of the operation panel 6 can be detected by, for example, arranging a mat-shaped pressure sensitive switch on the floor surface in front of the operation panel 6, but in this method, Since the jig can be used, it is desirable to use a detection method by the human sensor 15 or a detection method corresponding to the detection method as described above.

  Further, in this multi-story parking lot apparatus 1, since it is usually installed outdoors, for example, when sunlight is reflected on the ground in front of the operation panel 6 or sunlight is shining, the human sensor 15 may cause the operator's detection accuracy to deteriorate. In such a case, the human sensor 15 may perform appropriate processing on the signal input from the detection port to increase the detection accuracy. Or the eaves of a suitable magnitude | size may be provided in the operating panel 6 so that a shadow may be made on the ground in front of the operating panel 6, for example.

The main control unit 20 may exclusively input the contact switch 12a and the contact switch 15a. If the operator is not detected by the human sensor 15 even though it is detected that the operation button 12 has been pressed, an alarm may be output using, for example, Patlite (registered trademark) . Or you may make it transmit to the outside (for example, manager's room of an apartment) by communication.

  The scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, the configuration of the multilevel parking lot apparatus 1 in the above embodiment is not limited to the above configuration. For example, the number, form, size, structure, and the like of the operation panel 6 and the first to third control panels 21 to 23 are not limited to the above embodiment, and can be appropriately changed in design. Moreover, the pallet 2 shown by the said embodiment may be provided in a row in the left-right direction, and may be movable in the left-right direction.
