Hereinafter, the device of the present invention will be explained with reference to the drawings, divided into three cases: when the multilevel parking device is stopped, when it is leaving the parking lot, and when it is entering the parking lot.

First, when the multilevel parking device is stopped, that is, when the parking lot button 11 is
A case will be described in which both the and exit button 12 are not operated. In this case, signal line 3
2, 42, 43 are in low level state, signal line 41
is in a high level state, and the RS flip-flop 10 with negative elements 101 and 102 on the set input line
Since the flip-flops 4 and 105 act as positive logic storage circuit elements, the outputs Q of the flip-flops 104 and 105 are at a low level, and the outputs thereof are at a high level. Therefore, the gate of the AND element 107 is closed, and the receiving car signal inputted through the signal line (only 32a is shown in FIG. 3) is in a state of being cut off. On the other hand, since the cage of the AND element 108 is open, when the numeric keypad 13 is operated and a code signal is input to the AND element 108 through the signal line 33 (only 33a is shown in FIG. 3),
The code signal is the D-latch flip-flop 1 in the subsequent stage.
06 is input. This D latch flip-flop 106 outputs an output Q at the same level as the input D when the input T is at a high level, that is, when the delivery button 12 is not operated. When a signal is generated, this code signal is input to the logical sum element 113 at the subsequent stage, but unless the ten-key keyboard 13 is operated, a low level signal is always input to the logical sum element 113. Since the AND element 109 has its gate open, the signal line 31 (31a in FIG. 3)
The implantation cage signal input from the device (only shown in the figure) is input to the logical product element 110 at the subsequent stage, but if the numeric keypad 13 is operated, the coding device 2
2, at least one of the signal lines 33a to 33n changes from a low level state to a high level state.
The signal input to 0 becomes a low level state, closing the gate of AND element 110 and cutting off the landing cage signal.

Therefore, if the numeric keypad is not operated when the multilevel parking device is stopped, the landing cage signal from the landing cage detection device 20 is output to the OR element 1.
13, 114 and an AND element 111 to the display device 16, and the display device 16 displays a number corresponding to this implantation cage number. On the other hand, when the numeric keypad 13 is operated when the multilevel parking system is stopped, the gate of the AND element 110 is closed and the landing cage signal is cut off, but the D latch is activated through the AND element 108 whose gate is already open. The code signal is input to the OR element 113 via the flip-flop 106 and sent to the display device 16 through the OR element 114 and the AND element 111. Therefore, the display device 16 starts displaying a number corresponding to the cage number specified on the numeric keypad 13 from the number corresponding to the landing cage number.

Next, the case of the unloading operation will be explained. As mentioned above, when the multi-story parking system is stopped, when the exit cage is specified by operating the numeric keypad 13 and the exit button 12 is pressed, the signal line 43 is connected to the exit button 1.
However, due to the memory function of the RS flip-flop 105, the output Q of the RS flip-flop 105 remains at a high level while turning on the indicator lamp 15 through the signal line 45. Also RS
The output of flip-flop 105 remains in the low level state and outputs to D-latch flip-flop 106.
In order to maintain the input T of the D-latch flip-flop 106 at a low level, the output Q of the D-latch flip-flop 106
The code signal immediately before was pressed continues to be held.
Therefore, once the exit button 12 is pressed, the numbers displayed on the display device 16 do not change even if the numeric keypad 13 is operated from then on, and the numbers displayed on the display device 16 do not change through the signal line 30 (only 30a is shown in FIG. 3). A car signal corresponding to the outgoing car is input to the signal generator 23. When a delivery cage is specified by operating the numeric keypad 13 and the delivery button 12 is pressed, the specified delivery cage is called to the entrance/exit position by a well-known control device (not shown). At this time, the landing cage is detected. When the landing cage signal outputted by the device and the delivery cage signal outputted by the signal selection device 100 match, the signal generation device 23
Since a continuous pulse signal is input from the signal line 40 to the AND element 111, the AND element 1
11, the characters displayed on the display device 16, that is, the exit cage number, flash to notify the operator that the exit cage has arrived at the entrance/exit position. When a stop command is issued, the RS flip-flop 105 is activated through the signal line 41.
RS flip-flop 105 is reset to its initial state, and indicator light 1 is
5 is turned off, the signal generator 23 changes the continuous pulse signal on the signal line 40 to a high level constant signal, and the coding device 22 changes the code signal on the signal line 33 to a low level signal. Everything will then be reset.

Next, the case of warehousing operation will be explained. When the multi-story parking system whose landing cage number is displayed on the display device 16 is stopped, a user who wishes to park his/her car at the entrance/exit position of the multi-story parking system and presses the parking button 11, the signal line 42 is in a high level state only while the stocking button 11 is pressed, but due to the memory function of the RS flip-flop 104, the RS
The output Q of the flip-flop 104 remains in a high level state and lights up the indicator light 14 through the signal line 44 and opens the gate of the AND element 107, while the RS flip-flop 1
The output of 04 remains in a low level state, and the gate of AND element 108 is closed to cut off the code signal on signal line 33 (only 33a is shown in FIG. 3), and the gate of AND element 109 is closed. The landing cage signal on the signal line 31 (only 31a is shown in FIG. 3) is also blocked.

By the way, when the warehousing button 11 is pressed and the warehousing cage determination device 21 selects as the warehousing cage, for example, the empty cage closest to the entrance or the optimal empty cage that maintains a balanced load on the multilevel parking system, the signal line 32 (the In FIG. 3, only 32a is shown), the receiving cage receiving cage signal is input to the AND element 107 whose gate is already open, and is input to the display device 16 through the AND element 114 and the AND element 111. 1
6 displays a number corresponding to the storage cage number.
Thereafter, the designated storage cage is called to the entrance/exit position by a well-known control device, but at this time, as in the case of the above-mentioned unloading operation, the landing cage signal outputted by the landing cage detection device and the signal selection device 10
Since the continuous pulse signal is input from the signal generator 23 to the AND element 111 through the signal line 40 in agreement with the receiving cage signal outputted by 0,
By opening and closing the gate of the AND element 111, the characters displayed on the display device 16, that is, the warehousing cage number, flash to notify the operator that the warehousing cage has reached the entrance/exit position. When a stop command is issued, an instantaneous low-level signal is input to the reset input of the RS flip-flop 104, the landing cage detection device 20, the storage cage determination device 21, and the signal generation device 23 through the signal line 41. The RS flip-flop 104 is reset to the initial state, turns off the indicator light 14, and
The signal generator 23 changes the continuous pulse signal on the signal line 40 to a high level constant signal, and the incoming car determining device 21 changes the incoming car signal in the signal line 32 to a low level signal, so that everything is reset. be done.

As described above, according to the present invention, the output signal of the signal selection device is switched by operating the operation panel and inputted to the display device, so that the landing cage number, the receiving cage number, and the exiting cage number can be displayed on a single display device. It can be displayed in Therefore, the operation panel can be made as small as possible, and necessary information is immediately displayed on the display device in response to an operator's operation, so there are no problems in use. Furthermore, the present invention flashes the warehousing cage number and the warehousing cage number when the warehousing operation and the warehousing operation are completed, so that the operator can be reliably notified of the completion of the warehousing operation or the warehousing operation. can be performed smoothly.

In the above description, the display device including two sets of 7-segment display elements has been described as an example, but it is extremely easy to change the configuration of the display device depending on the number of parked vehicles that can be accommodated by the multi-level parking system.
