Description

Mechanical parking facility management system with self-diagnosis

The present invention relates to a warehouse location allocation system in a mechanical parking facility, and more particularly, to a mechanical parking system having a self-diagnostic function for easily correcting an abnormal occurrence of rack management related files for the warehouse location allocation. It relates to a facility management system.

In general, a mechanical parking facility is composed of several floors, each of which is a storage space of the vehicle. Mechanical parking facilities include a lift for moving the vehicle to each floor and a bogie for moving the vehicle horizontally at each floor. Here, each floor is referred to as a tier, and each tier has a plurality of rows with racks that are storage spaces of the vehicle. Each row consists of several addresses, and the parking information of the vehicle is determined by the combination of the steps, rows, and addresses. The entrance and exit location allocation system of this mechanical parking facility is operated unattended automatically and determines and corrects the entrance and exit location of the vehicle.

When it is necessary to change the priority of the warehouse at the mechanical parking facility, the user reprograms the contents of the warehouse allocation. In addition, for the programmed contents, the parking lot entry and exit locations were actually assigned and the result was confirmed. However, there is a problem that it is not only cumbersome but time-consuming to check the results through actual experiments whenever the contents are changed. In order to solve this problem, a simulation system is proposed to set the priority of the receipt of the parking space in various ways and to simulate the function when changing the priority as needed or automatically changing the priority over time. It became.

The warehouse location allocation system has a separate database for the initial setting of the parking facilities, the reservation status, and the setting of the storage priority. This database contains the default rack management files formatted for the parking facility. In other words, if a new parking facility or parking location is changed, new files must be created accordingly, and the rack status must be entered in the created file. In addition, modifications to this database can only be made by professional programmers. This can lead to a serious parking failure if there is a problem with the database file.

Accordingly, it is an object of the present invention to provide a mechanical parking facility management system having a self-diagnosis function that enables self-diagnosis and easy correction of abnormality of a database file upon system startup.

As shown, the system of the present invention includes a database 15 for storing a reservation information file, a rack status file, and a goods receipt ordering file for the initial setting of the parking facility, the reservation status, the goods receipt priority setting, and the like. . The entrance and exit location assignment management unit 13 diagnoses the occurrence of abnormality of each file stored in the database 15 at startup and manages the entrance and exit location assignment of the parking. The system of the present invention also has a display portion 14 for displaying the relevant contents for the user to monitor through the simulation process. Parking control PLC (Programmable Logic Controller) (12) is responsible for allocating the warehouse location of the vehicle, and sends and receives data through communication with the warehouse location assignment management unit (13). The parking control PLC 12 and the storage location assignment management unit 13 are connected to each other via RS-232C. On the other hand, the system of the present invention is provided with a control panel 11 to notify the user of the occurrence of abnormalities according to the self-diagnosis of the entry and exit position allocation management unit 13 to correct.

In Fig. 1, the parking control PLC 12 shows a system that can simulate the function of the entry and exit position allocation management unit 13 even without performing a normal sequence. First, before explaining the self-diagnosis function of the present invention, the simulation process will be outlined.

The parking control PLC 12 and the storage location allocation management unit 13 transmit and receive data by performing serial communication through RS-232C, and monitor the status of the parking control PLC 12 at the storage location allocation management unit 13 from time to time. . When a specific I / O address value of the parking control PLC 12 is changed into a command related to the entry and exit position allocation, the entry and exit position allocation management unit 13 recognizes the command status of the parking control PLC 12 and performs a command related to the position allocation. do. The entrance and exit location assignment management unit 13 transmits the result to the I / O address indicating the result of the parking control PLC 12.

More specifically, the entry and exit position assignment management unit 13 monitors the command status of the parking control PLC 12. Then, the display unit 14 is controlled to display the command status in the parking control PLC 12. The user may view the display unit 14 and monitor the command status of the parking control PLC 12. The display unit 14 displays the command I / O codes in the parking control PLC 12 and the function and role of the address corresponding to each code to help the user to simulate. The user may change the command I / O code to a desired value through a key input means not shown. The display unit 14 shows the address value of the current command I / O code and the change address value set by the user. The entrance and exit location assignment management unit 13 transmits the address value changed by the user to the parking control PLC 12 and controls the parking entrance and exit location assignment. On the other hand, when the entrance and exit location assignment result in the parking control PLC 12 according to the performance is displayed on the display unit 14, the user can monitor the performance results while viewing the display unit (14). The user can change the entry and exit position allocation information through the key input means. The entrance and exit location assignment management unit 13 transmits the changed address value to the parking control PLC 12 as the address value of the result I / O code.

As such, even when the parking control PLC 12 does not perform a normal sequence, the entrance and exit location assignment result can be immediately known, and a desired function can be simulated by the user.

Next, the process of performing the self-diagnosis function of the present invention will be described.

When the rack management is started or when the parking control PLC 12 is initialized or when the parking information is changed according to each operation state, the input and output location allocation management unit 13 reserves the reservation information file, the rack status file, and the storage order in the database 15. Access the specified file. Among the files stored in the database 15, the rack status file manages the insulation address information indicating the parking position, the key number which is the serial number of the parking vehicle, the presence or absence of parking at each parking position, that is, the rack status information, the goods receipt and shipping time. do. Here, the key number is a serial number corresponding to each parking position to be described in the parking ticket possessed by the driver to recognize the parking position of the vehicle. The reservation information file manages the key number of the reserved vehicle, the reserved parking location insulation address information, the entry and exit classification status, the operation status, and the processing time information. Receiving priority designation file manages the information that the receiving priority of each stage is assigned by ten. Here, priority is given to the floors (floors) with many empty parking locations, and priority is given in the order of address of each row. The entry / exit location allocation management unit 13 sets in advance errors (eg, overlapping priority designations) that may occur in each of the files stored in the database 15. The entry and exit position assignment management section 13 diagnoses whether or not a preset abnormality has occurred in the files in the database 15 at the entry and exit position allocation start. Entry and exit position allocation management unit 13 transmits the contents to the parking control PLC 12 via the RS-232C when a diagnosis result abnormality occurs. The parking control PLC 12 receives the abnormality and displays it on the screen of the operation panel 11 so that the user can know it. The user recognizes the abnormality through the operation panel 11 and then corrects the file in which the abnormality occurs through the parking control PLC 12. The user can modify only the rack status file in the database 15, and the reservation information file and the goods receipt ranking designation file are modified by the entry / exit location allocation management unit 13 itself.

On the other hand, the entry and exit location allocation management unit 13 can be modified so that there is no rack status file or the goods receipt ranking designation file in the database 15, or when the specification of the parking equipment is changed in advance, the modified back-up file can be modified accordingly. do. Then, when the user requests the initialization through the parking control PLC 12, the storage location assignment management unit 13 initializes the parking facility state with the parking information defined in the reference backup file.

In this way, upon request for the initialization of parking information, the warehouse location assignment management unit 13 allows the vehicle to be changed to the initial state of the parking facility, and is corrected through self-diagnosis even when the facility is restarted or the file 15 of the database 15 is defective. Make it possible to drive.

As described above, the mechanical parking facility management system having the self-diagnosis function of the present invention self-diagnoses the database for the operation of the parking lot entry and exit position allocation at the start-up, thus preventing the malfunction of the parking facility due to the abnormality of the file in the database.
