The present invention relates to a technique for preparing a malfunction of various sensors for detecting the driving of the lift in a multi-layered circulation parking system, in particular, the machine is damaged due to malfunction or failure of the proximity sensor, limit switch when the lift is moving up or down The present invention relates to a method of operating a multi-layered circulation parking system that is suitable for preventing the motor from being burned out.

1 is a schematic diagram of a conventional multi-tiered parking facility according to the related art, in which the rotation rails 4, 5, 6, 7 in the lift in the main part 1 are connected by a chain. The pallet 8, which is circulated in the vertical direction and placed in the main part 1 and the parking compartment 2, is traversed along the rail to each floor of the parking compartment 2, which is a pallet of the first and second floors. (8) is traversed in a pair, or the pallet 8 of a 2nd and 3rd floor is transversed in a pair.

In the periphery of the rotation rail 5 in the main unit 1, the up / down proximity sensor 9 and the down / down acceleration sensor 12 for detecting the rising and falling state of the rotation rail, the proximity sensor 10 for stopping, 11) is installed, the sub-unit 3 is installed at a position corresponding to the main unit 1 with respect to the parking room (2) for efficient parking management.

Here, reference numeral "13" is a lower limit overrun limit switch, "14-16" is a floor position correct position photosensor, "17" is a deceleration limit switch, "18" is a stop limit switch, "19" is an upper limit overrun limit The switch, "20-28", is a pallet in-position fiber sensor for each layer.

FIG. 2 is a control block diagram of a conventional multi-circulation circuit parking facility. As shown therein, a numeric key input unit 41A, a display unit 41B, and a lamp 41C are provided, and numbers required to enter and exit a vehicle. An operation panel 41 for inputting a key and displaying a parking status or a warning status; An external switch signal input unit 42 for accepting limit switches, proximity switches, and sensor inputs installed at each part of the parking facility; It is composed of a central processing unit, ROM and RAM, PL C (43A) having EPIROM, inverter (43B), (43C) and according to the signal input from the operation panel 41 or the external switch signal input unit 42 Consists of a control panel 43 to oversee the control function for the entry and exit of.

Referring to Figures 3a, 3b attached to the operation of the conventional parking facility configured as described above are as follows.

When the parking facility manager presses the wear button to park the vehicle, the system searches for an empty pallet with the lift of the main part 1 and the sub part 3 lift in place. Here, the position in position is a state in which the two-layer photo sensor 3 of the main unit 1, the two-layer photo sensor 38 of the sub-unit 3, and the stop proximity sensors 10, 11, 33, and 34 are operated. Say.

If the vehicle is emptied without being loaded on the pallet No. 13 located on the second floor of the main part 1, the lift of the sub part 3 does not travel and only lifts the main part 1. The vehicle starts traveling in the ascending direction toward the entrance surface with the empty pallet 8 loaded. However, if the empty pallet 8 does not exist in the main part 1, the pallet 8 of the parking compartment 2 is traversed until the empty pallet 8 exists, in which case the second and third floors are traversed. Or traverse the first and second floors.

After starting the driving in the upward direction as described above, if the proximity sensor 9 for deceleration is operated by the rotation rail 4, that is, when the rotation rail 4 is detected by the proximity sensor 9 for deceleration, the above-described operation is performed. The lift of the main unit 1 starts to rise in a decelerated state, and then continues to ascend without stopping even when the third-position photoelectric sensor 16 operates.

Subsequently, when the lowering deceleration proximity sensor 12 is operated by the rotation rail 4, the lift is switched from the deceleration mode to the acceleration mode, and then the rising / deceleration proximity sensor 9 and the descending deceleration proximity sensor 12 are performed again. ), The driving mode is not changed and only the number of rotation rails is counted.

However, when the lift is further raised and the deceleration limit switch 17 is operated by the rotation rail 44, deceleration travel starts from this time, and the driving is stopped when the stop limit switch 18 operates.

At this time, the door is opened and the vehicle waiting at the entrance surface is loaded on the pallet 8 which is raised to the entrance surface through the above process.

After loading the vehicle on the pallet 8 raised to the entrance surface through the above process, press the cancel button to close the door and the lift begins to descend. At the time of falling, deceleration is not performed until all the counted values during the ascent are reset, and if the descending deceleration proximity sensor 12 is operated by the rotation rail 4 after the count value is reset, the lift is decelerated from this time. The mode is lowered.

As the lift of the main part 1 passes through the third floor, it continuously descends to the deceleration mode and then starts to descend to the acceleration mode from the time when the up / deceleration proximity sensor 9 is operated by the rotation rail 4. When the proximity sensor 12 for deceleration and deceleration is operated by the rotation rail 45, the vehicle is driven in the deceleration mode and stopped.

When the system is stopped, the correct position photosensor 15 installed on the second floor of the main part 1 is operated, and the stopping proximity sensors 10 and 11 must be operated. At this point the goods receipt is complete.

However, in such a conventional parking facility, when the lift is moving up or down, if the malfunction of the deceleration proximity sensor for deceleration of the main lift, the deceleration limit switch and the deceleration proximity sensor of the sub lift occurs, the lift continues to move up or down. There was a defect that caused an accident, resulting in property damage.

Therefore, the technical problem to be achieved by the present invention is to remember the normal operation reaction time of the proximity sensor and the limit switch when the lift in the lifting or lowering operation in the multi-tiered parking system safety when the reaction does not respond until the time elapses The present invention provides a method of operating a multi-tiered cycling parking facility that takes action.

In order to achieve the object of the present invention, the operation method of the multi-purpose circulating parking facility checks the time from the lift start mode to the operation of the proximity sensor for deceleration after the lift starts the lift ascending time (tmr1). A first step of checking the time from the time of switching to the high speed mode until the deceleration limit switch is operated by the rotation rail and setting the lift ascending time tmr2; In lift lowering mode, after the start of lowering, check the time until the proximity sensor for lowering and deceleration is operated by the rotation rail, and set it as the lift lowering acceleration time (tmr3), and the acceleration sensor for upward and deceleration is operated by the rotation rail. A second step of checking the time from the time point until the proximity sensor for deceleration is operated by the rotation rail and setting the lift deceleration acceleration time tmr4; In the lift ascending mode, until the lift ascending time (TMR1 = tmr1 + 1) has elapsed after the lift has started the ascending run, the proximity sensor for deceleration or deceleration is not operated by the rotation rail, or the lift ascending speed is changed after switching to the high speed mode. If the deceleration limit switch does not operate by the rotation rail until time (TMR2 = tmr2 + 1) has elapsed, it is determined that an abnormality has occurred in the corresponding proximity sensor or limit switch, and the system is stopped. A third step of registering an error code; In lift lowering mode, the lowering / deceleration proximity sensor is not operated by the rotation rail until the lift lowering acceleration time (TMR3 = tmr3 + 1) elapses after the lift starts lowering on the entrance surface. If the proximity sensor for deceleration and deceleration is not operated by the rotation rail until the lift down acceleration time (TMR4 = tmr4 + 1) has elapsed, the system determines that the proximity sensor has an error and stops the operation of the system. In addition, a fourth process of registering a corresponding error code will be described in detail with reference to FIGS. 1 and 2, 4A, and 4B attached to the operation of the present invention.

When the parking facility manager presses the wear button to park the vehicle, the system searches for an empty pallet with the lift of the main part 1 and the lift of the sub part 3 in the correct position. Here, an explanation will be given by taking an example in which a parking space is designed as three floors and the intermediate floor is used as a reference floor for driving.

If the vehicle is emptied without being loaded on the pallet No. 13 located on the second floor of the main part 1, the lift of the sub part 3 does not travel and only lifts the main part 1. The vehicle starts traveling in the ascending direction toward the entrance surface with the empty pallet 8 loaded. First, the process of setting the lift ascending acceleration times tmr1 and tmr2 and the lift descending acceleration times tmr3 and tmr4 will be described. Is as follows.

If the lift decelerating proximity sensor (9) is operated by the rotation rail (4) while driving the ascension in the deceleration mode from this time, as described above, after the lift starts the ascent drive, the deceleration proximity sensor (9) Check the time until it is operating and set it as the lift ascent time (tmr1).

Thereafter, the lift is decelerated without stopping, regardless of the operation of the three-layer fixed position photosensor 16 and the proximity sensors 10 and 11 for stopping, and then the descending deceleration proximity sensor 12 by the rotation rail 4. When is operated, it is switched from the deceleration state to the acceleration state.

Thereafter, when the rotation rail 5 is out of the three-layer fixed position photo sensor 16, only the number of the rotation rails is counted until the deceleration limit switch 17 is operated. And 12) and the previous acceleration state is maintained as it is regardless of the operation of the stop proximity sensors 10 and 12.

Subsequently, when the deceleration limit switch 17 installed near the entrance by the rotation rail 6 is operated, the lift is driven in the deceleration mode. From this time, the rotation rail ( 6) checks the time until the deceleration limit switch 17 operates and sets it to the lift ascending acceleration time tmr2.

When the stop limit switch 18 is operated through the above process, the lift stops driving and stays in a wearing standby state.

When the entrance detecting limit switch 6 of FIG. 1 is operated, the lift stops and the wear wait state is reached. If you press the Cancel button when the loading is completed, the lift will descend after the door is closed.

At this time, the door is opened and the vehicle waiting at the entrance surface is loaded on the pallet 8 which is raised to the entrance surface through the above process.

After loading the vehicle on the pallet 8 raised to the entrance surface through the above process, press the cancel button to close the door and the lift begins to descend. At the time of falling, deceleration is not performed until all the counted values during the ascent are reset, and if the descending deceleration proximity sensor 12 is operated by the rotation rail 4 after the count value is reset, the lift is decelerated from this time. The mode is lowered.

In this way, after the lift starts to descend, the time until the down / down proximity sensor 12 is operated by the rotation rail 4 is checked, and the time is set to the lift down acceleration time tmr3.

Thereafter, the rotation rail 5 passes through the three-layer fixed position photosensor 16 in the deceleration mode, and then switches to the acceleration mode when the proximity sensor 9 for the acceleration and deceleration is operated by the rotation rail 4 to continue. While driving down, when the proximity sensor 12 for deceleration and deceleration is operated by the rotation rail 5, the vehicle switches to the deceleration mode again and stops while driving down.

As such, the time from the time when the up / down proximity sensor 9 is operated by the rotation rail 4 to the down / down proximity sensor 12 is operated by the rotation rail 5 is checked and lifted. Set to fall acceleration time (tmr4).

Criteria for detecting malfunction of each sensor and limit switch by adding a predetermined delay time to the acceleration time (tmr1-tmr4) checked and stored by each sensor and limit switch while the lift is moving up and down through the above process. Is set to acceleration time (TMR1-TMR4), and it is stored in YPIROM in PLC 43A in the control panel 43.

On the other hand, when the system is operated again after storing the acceleration time (TMR1-TMR4) of the reference for detecting malfunction through the above process, the malfunction of each sensor and limit switch is based on the acceleration time (TMR1-TMR4). Will be detected.

That is, in the lift ascending mode, the lift-deceleration proximity sensor 9 is operated by the rotation rail 4 until the lift ascending acceleration time (TMR1 = tmr1 + 1) set above is elapsed after the lift starts the ascending run. If it does not operate as a result, it is determined that a failure or abnormality has occurred in the proximity sensor 9, so that the system stops driving and registers the corresponding error code. (ST8-ST11)

Thereafter, after switching to the high speed mode, it is checked whether the deceleration limit switch 17 is operated by the rotation rail 6 until the lift-up acceleration time (TMR2 = tmr2 + 1) set above is elapsed. If the result does not operate, it is determined that a failure or abnormality has occurred in the deceleration limit switch 17, the operation of the system is stopped, and the corresponding error code is registered. (ST15-ST18)

Also, after the lift starts to descend from the entrance surface, it is checked whether the descending deceleration proximity sensor 12 is operated by the rotation rail 4 until the lift lowering acceleration time (TMR3 = tmr3 + 1) set above is elapsed. If it is not operated, it is determined that a failure or abnormality has occurred in the descending deceleration proximity sensor 12, and the operation of the system is stopped and the corresponding error code is registered. (ST27-ST30)

Subsequently, the descending deceleration proximity sensor 12 is rotated by the rotation rail 5 until the lift lowering acceleration time TMR4 = tmr4 + 1 of the reference set in the elapsed time after the ascending deceleration proximity sensor 9 is operated. If it does not operate by checking whether the operation is in progress, it is determined that a failure or abnormality has occurred in the descending deceleration proximity sensor 12, and the operation of the system is stopped and the corresponding error code is registered. (ST34-ST37)

In the above description, when each sensor or switch does not operate normally, the system is stopped as it is, but at this time, the sensor or switch is treated as operating and converted to the operation mode accordingly, but the error code is registered as described above. By doing so, the user can recognize the fact and cope with the failure.

As described in detail above, the present invention stores the normal operation reaction time of the proximity sensor and the limit switch when the lift moves up or down in the multi-layered circulation parking facility, but does not respond until the time elapses. By registering the code and stopping the system operation or performing emergency operation, it is possible to prevent the safety accident in advance.
