Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking equipment management apparatus used in the field of maintenance services such as finding and repairing equipment abnormalities in a multi-story parking lot having a plurality of parking pallets.

[0002]

2. Description of the Related Art Multi-tiered multi-storey parking lots having two or more tiers of parking pallets are often operated without a dedicated manager resident in the parking lot. Therefore, the maintenance service provider needs to accurately grasp the contents of the abnormality when an abnormality occurs in the parking facility located at a remote place.

On the other hand, conventionally, there has been a technique in which abnormality content information detected by a control unit of a multi-level parking facility is coded, and this code is displayed on a panel or the like of the control unit so that a user of a parking lot can read it. .

However, in the method of causing the parking lot user to read the abnormality content code displayed on the panel of the parking facility as described above, the parking lot user rarely reads it, and if it does. However, the accuracy of the information transmission is often lacking, such as the read code being transmitted to the administrator side through some people. Even if the code indicating the abnormality is displayed when the parking facility is stopped, the parking lot user is usually away from the code display panel of the control unit, and the code display panel is displayed for the purpose of moving the pallet. Since the abnormal content code is read for the first time when approaching, there was a problem that the transmission of the code was delayed.

In addition, when there is a maintenance service provider in a remote place, when the parking lot user obtains the information of the abnormality content as described above, the parking lot user is requested to investigate the cause of the abnormality by using a motor. In many cases, we ask the driver to move the driving part with a manual switch to test the operating condition. However, in this case, the parking lot user may feel uneasy about operating a manual switch, which he is not familiar with, and hesitate to manually operate.

[0006] Further, the regular maintenance of the multi-storey parking facility is usually performed based on the operating period of the parking facility, but the actual operating frequency of the parking facility varies depending on each parking facility. It is more efficient and rational to manage the maintenance period based on the number of times a vehicle is put in and taken out, that is, the number of times a parking pallet is operated, than when the period is used.

Therefore, a first object of the present invention is to enable accurate and speedy acquisition of abnormality information of a parking facility in a remote place, which was difficult for a maintenance service provider as described above.

A second object of the present invention is to enable a maintenance service provider to test drive the parking facility by remote control when abnormality information of the parking facility is obtained, and to investigate the cause of the trouble. To do.

A third object of the present invention is to notify an efficient maintenance time by automatically transferring the information to the maintenance service provider when the number of times the parking pallet has been operated reaches a prescribed number. It is in.

[0010]

SUMMARY OF THE INVENTION The present invention, which was developed to achieve the above object, has a parking pallet, a pallet driving mechanism for moving the pallet vertically or laterally, and the pallet driving mechanism for a parking lot. A parking facility management device for managing a parking facility including an operation panel used when a user operates, a sensor for detecting the state of the parking facility, and the pallet drive mechanism are operated. By outputting a control signal to the drive unit of the pallet drive mechanism and inputting the signal of the sensor, it is detected whether or not an abnormality has occurred in this parking facility, and when abnormality is detected, a state indicating abnormality information When a parking lot side control unit that creates a display code and a state display code issued by the parking lot side control unit that is provided in a remote place apart from the parking facility are received In addition, the management control unit equipped with a computer that decodes the status display code to determine the operating status of the parking facility, and connects the parking lot side control unit and the management control unit via a public line. Further, it is characterized by comprising a communication means for transferring the status display code sent by the parking lot side control section to the management control section through the public line.

The parking facility is preferably provided with a pallet drop prevention mechanism for preventing the pallet from dropping when the pallet is stopped at the raised position, and a pallet opening / closing mechanism provided at the entrance / exit of the vehicle and opened / closed as necessary. It is equipped with a safety gate that can be used.

Further, when the management control unit receives the code indicating the abnormality information from the parking lot side control unit, the management control unit drives the parking lot side control unit to investigate the abnormal state of the parking facility. There is provided means for transmitting a remote control command code for operating the unit through the public line. Further, the parking lot side control unit is provided with means for constantly counting the number of times the parking pallet has been operated, and a pallet operation number code related to the count number is automatically transferred to the management control unit through the public line. It is equipped with a means to do.

[0013]

In the case of an elevating type parking pallet, this pallet is vertically driven by a pallet driving mechanism using a hanging chain, a sprocket and a motor. Then, the lowered position or raised position of the pallet is detected by a sensor such as a limit switch. In the case of a traversing type parking pallet, the pallet is driven in the horizontal direction by a pallet driving mechanism including rails extending in the horizontal direction.

For example, when the elevating pallet is in the ascending state, if the vehicle on the pallet is to be unloaded, the parking lot user himself operates the operation panel to lower the pallet so that the vehicle on the pallet can be unloaded. To do. In this case, the driving control program installed in the parking lot side control unit first lowers the safety gate and confirms the input from the sensor that detects that the gate has reached the lower end, Ends the descent of. After that, the pallet drop prevention mechanism is moved in the releasing direction, the input of the sensor that detects the release of the fall prevention hook and the like is confirmed, and then the motor of the pallet drive mechanism is activated to lower the parking pallet. Then, by confirming the input from the sensor that detects that the pallet has reached the lowering end, the safety gate is raised after the pallet lowering is completed, and the vehicle is ready to leave.

During the series of operations described above, for example, a signal from a sensor to be input cannot be confirmed, or conversely, a signal is input from a sensor that should not be input.
Alternatively, when it is detected that an overcurrent has flown to the motor of the pallet drive mechanism or the motor of the gate drive mechanism, the parking lot side control unit determines that an abnormality has occurred in this parking facility and determines whether the parking facility operates. Emergency stop.

When the parking facility is in an emergency stop, the parking lot side control unit determines which of the predetermined abnormality content codes corresponds to the abnormal state, and the code and all of the input / output units of the control unit. A state display signal indicating the state is automatically transferred to a management control unit at a remote place through a public line such as a telephone line together with a recognition code of the control unit itself of the parking facility through a public line such as a telephone line. The control unit for management using a microcomputer decodes the transferred code, and which of the parking facilities in multiple areas is stopped in which abnormal state and input / output state? Notify the maintenance service provider.

Further, for example, when an attempt is made to lower the pallet and the pallet stops abnormally without inputting a signal from the sensor for detecting the lowering edge, the maintenance service provider who has obtained this abnormal information to the management control unit. While contacting the parking lot users, it issues a remote control command code for pallet driving to the parking lot side control unit from the computer of the management control unit via the public line to temporarily raise the pallet. You can check if there are any foreign objects such as stones between the pallet and the floor.

In this case, even if the parking lot user does not have to operate the manual switch, the pallet can be moved by the remote operation performed by the maintenance service provider. There is no problem to give.

The above parking lot side control unit always counts the number of times the pallet is operated (for example, the number of times it is moved up and down), and when this number reaches a prescribed value, the information is coded and the same as the above-mentioned abnormality content code. Notify the remote maintenance service provider of the time of maintenance through the public line.

The control unit 72 includes sensors 35, 40, 4
Based on the signals transmitted by 1, 50, 51, 52, 63,
Judging whether or not an abnormality has occurred in this parking facility 10,
A program that creates a predetermined abnormality content code when it is determined to be abnormal is incorporated. Further, the control unit 72 constantly counts the number of times the pallet 15 has operated, and creates a pallet operation number code. Further, the computer 9 of the management control unit 95 described later
It is also possible to receive the remote control command code sent from the computer 7.

An operation panel 83 used by a parking lot user to move the pallet 15 is connected to the input / output section 75, and operation information output from the operation panel 83 is input to the control section 72. At the same time, input / output information is stored in the memory 74.

A serial communication circuit 86 is connected to the CPU 73 of the control section 72, and this serial communication circuit 8
A serial signal for communication can be exchanged between the 6 and the modem 87. The controller 72 and the serial communication circuit 86 form a controller 88.

A public line 90 such as a telephone line is connected to the modem 87. The public line 90 is connected to a modem 96 of a management control unit 95 located at a position distant from the parking facility 10, and a signal can be exchanged with the management computer 97 via the modem 96. Has become.

In other words, the abnormality content code created by the parking lot control section 72, the equipment recognition code for each parking lot in each place, the pallet operation frequency code, etc. are used as the public line 90.
Is automatically transferred to the management control unit 95 through
If necessary, a remote control command code sent from the management computer 97 is sent via the public line 90 to the parking lot side controller 7.
You can enter in 2. Therefore, the modem 8
7, 96 and the public line 90 and the like constitute a communication means 98.
When a plurality of parking facilities 10 are present, the control units 72 of the parking facilities 10 at various locations can send and receive the above codes to and from one management control unit 95.

The management computer 97 incorporates a program for decoding the abnormality content code sent from the parking lot side control unit 72 and managing the operating state of the parking facility 10. Moreover, when the above-mentioned abnormality content code is received, this management computer 97 also incorporates a program for transmitting the remote operation command code to the parking lot side control unit 72 through the public line 90 in order to investigate the cause of the abnormality occurrence. Has been. Further, the management computer 97 is installed with a program for receiving a pallet operation number code sent from the parking lot side control unit 72 when the number of operations of the pallet 15 reaches a predetermined value.

Next, the operation of the apparatus having the above-mentioned structure will be described. For example, when it is desired to leave the vehicle on the pallet 15 in the ascending state, the parking lot user operates the operation panel 83 to operate the drive unit 80 via the control unit 72 to operate the pallet 15. Is lowered so that the vehicle on the pallet 15 can be unloaded. In this case, the operation control program incorporated in the control unit 72 first drives the gate drive motor 46 to lower the safety gate 20, and confirms the input from the lowering edge detection sensor 50 to confirm the gate 20. Ends the descent of.

After that, the actuator 62 of the pallet drop prevention mechanism 17 is moved in the releasing direction to confirm the input of the hook confirmation sensor 63, and then the pallet drive motor 3
The pallet 15 is lowered by rotating 0. Then, after confirming the input from the descending end detection sensor 40, the descent of the pallet 15 is completed, and thereafter the gate 20 is raised by the gate drive motor 46, and the vehicle is ready to leave.

During the above-mentioned series of operations, the signals from the sensors 40, 50 to be input cannot be confirmed, or conversely, the signals are input from the sensor which should not be input.
Alternatively, when the overcurrent sensors 35 and 52 are activated, the parking lot side control unit 72 determines that an abnormality has occurred in the parking facility 10 and causes the parking facility 10 to stop operating urgently.

In this way, when the parking facility 10 is in an emergency stop, the parking lot side control unit 72 determines which of the predetermined abnormality content codes corresponds to the abnormal state, and the code (abnormality content code) and The status display code indicating all the states of the input / output unit 75 is automatically transferred to the management computer 97 through the public line 90 by a serial signal together with the identification code of the control unit 72 itself. Computer 9
7 decodes those codes and informs the maintenance service provider of which parking facility 10 is stopped in what abnormal state and input / output state.

Further, for example, when the pallet 15 is lowered and the pallet 15 is abnormally stopped without inputting the signal from the lowering edge detecting sensor 40, this abnormality information is obtained to the management control section 95. The maintenance service provider, while communicating with the parking lot user, issues a remote operation command code for driving the pallet from the management computer 97 to the parking lot side control unit 72 via the public line 90.
In this case, for example, a test of temporarily raising the pallet 15 can be performed to confirm whether there is a foreign substance such as stone between the pallet 15 and the floor. Therefore, even if the parking lot user does not have to operate the manual switch, the pallet can be moved by the remote operation performed by the maintenance service provider, which causes the parking lot user to feel uneasy in operation. Also disappears.

Further, the parking lot side control unit 72 controls the pallet 15
Is always counted, and when this number reaches a specified value, the information is coded and is sent through the public line 90 in the same manner as the status display code (abnormality content code etc.). Notify the maintenance service provider that the maintenance time has come.

[0042]

According to the present invention, when an abnormality occurs in a parking facility such as a multi-storey parking lot in a remote place and the facility is brought to an emergency stop, the maintenance service provider can receive accurate information immediately. Since it is transmitted, the coping method can be actively and promptly presented to the parking lot user. Even if an abnormality occurs in the sensor input status while the parking pallet is stopped, the maintenance service provider is immediately notified of the occurrence of the abnormality, so it is possible to take appropriate measures before operating the pallet. Becomes

Further, since the maintenance service provider can operate the drive unit of the parking facility that has been stopped in an emergency from a remote location, the operation of the drive unit necessary for investigating the cause of the abnormality is manually performed by the parking lot user. It is possible without depending on the operation. Further, since it is possible to inform the maintenance service provider at a remote place of an appropriate maintenance time based on the number of times of pallet operation, efficient management can be realized.
