Hereinafter, embodiments of the present invention will be described with reference to the drawings and the like. Note that the present invention can be implemented in many different modes and should not be construed as being limited to the description of the embodiments given below.

[Configuration of parking device]
FIG. 1 shows a main configuration of a parking device 100 according to one embodiment of the present invention. FIG. 1 is a schematic view of the parking device 100 as viewed from the side (in a case where a surface having a doorway is the front).

  The main structure of the parking device 100 is constituted by columns 102, and a plurality of pallets 104 on which the vehicle is mounted are installed in the main structure. The pallet 104 is provided so as to be able to move up and down along the column 102 by a pallet moving mechanism 113. The pallets 104 in the main structure are provided at intervals such that the vehicles do not interfere with each other when a plurality of vehicles are stacked in the vertical direction. As a result, the main structure formed by the pillars 102 forms a parking space that is vertically stacked in a plurality of stages.

  Although not shown, a plurality of parking spaces may be formed not only in the vertical direction but also in the horizontal direction (the depth direction shown in FIG. 1). Thus, the pallet 104 can be moved along the column 102 not only in the vertical direction but also in the horizontal direction.

  The parking device 100 is operated by a parking device operation panel 114. The operation panel 114 is provided outside the parking device 100. For example, the operation panel 114 may be attached to the column 102 near the entrance / exit of the parking device 100 (the lower right side in FIG. 1). The user operates the operation panel 114 from outside the parking device 100 to move the target pallet 104 to the entrance / exit port.

  The safety gate 116 provided at the entrance of the parking device 100 can be opened and closed by the operation panel 114. The safety gate 116 is in a closed state when the pallet 104 is lifted and lowered, and when the pallet 104 is not opened for loading and unloading the vehicle. The closure of the safety gate 116 prevents a person from normally entering the parking device 100. The signal output from the operation panel 114 is sent to the control panel 117, and the control panel 117 outputs a signal for raising / lowering the pallet 104 and opening / closing the safety gate 116.

  In the parking device 100 that forms a parking space stacked in a plurality of stages in the vertical direction by the main structure and stores and parks the vehicle in a three-dimensional manner, the pallet 104 moves up and down, so that the target pallet 104 is loaded and unloaded. Move to the mouth and put the vehicle in and out. There are several methods of moving the target pallet 104 to the entrance / exit, for example, a method of sinking the lower pallet 104 into the underground pit to unload the vehicle parked on the upper pallet 104, A method in which the lower pallet 104 is slid in the lateral direction of the vehicle body to lower the upper pallet 104 or a method in which these are combined is adopted.

  The example shown in FIG. 1 shows an aspect in which parking spaces P1, P2, P3, and P4 are provided from the first floor to the upper floor. It is also assumed that a parking space P5 (not shown) is provided in the lateral direction of the parking space P1. At this time, the pallets 104 in the lower parking spaces P1, P2, and P3 are obstacles for lowering the pallet 104 parked in the upper parking space P4 and entering / leaving the vehicle. In this case, if the pallet 104 in the parking space P5 is raised and the pallets 104 in the parking spaces P1, P2, and P3 are slid in the horizontal direction, there is no obstacle, so the pallet 104 in the parking space P4 is lowered to the entrance. Becomes possible.

[Configuration of parking device operation panel]

  The parking device 100 may be powered on by inserting the operation key 114-4 into the recess of the operation power switch 114-3. The operation power switch 114-3 is also a locking means of the parking device 100, and the locking is released by a key means suitable for the locking means and the operation becomes possible. As the key means, a key that fits into a cylinder lock, a dial-type key, a password-type key, a magnetic card or an IC card can be used. Hereinafter, a case where a key with a blade is used as an example of the key means will be exemplified, and the key means will be referred to as “operation key 114-4”.

  In using the parking device, the operation can be performed by inserting the operation key 114-4 into the keyhole of the operation power switch 114-3 and turning it from “off” to “on”, for example. When the operation key 114-4 is turned to "ON", the operation key 114-4 cannot be removed from the operation power switch 114-3. To remove the operation key 114-4 from the operation power switch 114-3, the safety gate 116 is closed by turning the operation key 114-4 to a position of "gate closed" between "on" and "off". In addition, the parking key cannot be removed unless the operation key 114-4 is further turned to the "off" position to turn off the power of the parking device.

  The operation explanation part 114-6 is a part showing a basic operation procedure of the parking device. A lighting lamp and operation buttons may be arranged in the operation explanation section 114-6 for each operation procedure. The user performs an operation by pressing an operation button or the like according to the operation procedure shown in the operation explanation section 114-6. At this time, for example, a “safety confirmation button” for inputting the confirmation by pressing the user after confirming whether or not there is a person in the parking device may be displayed. The safety gate 116 may be opened by pressing the “safety confirmation button”.

  The user inputs the number of the pallet 104 to be called by pressing a switch of the input unit 114-2. The number input by the input unit 114-2 is displayed on the display unit 114-1. The user can check the number input from the input unit 114-2 on the display unit 114-1. The number of the pallet 104 input from the input unit 114-2 is transmitted from the operation panel 114 to the control panel 117 as an output signal, and the control panel 117 sends a signal to the pallet moving mechanism 113 to move the pallet 104 of the number up and down. Is output. As a result, the pallet moving mechanism 113 moves the target pallet 104.

  The emergency stop button 114-5 can be stopped by pressing this button when the moving pallet 104 is to be urgently stopped. Thus, the basic operation of the parking device 100 can be performed by the operation panel 114.

  As illustrated in FIG. 3, the control device 11 includes a measurement unit 11-1, a storage unit 11-2, and a communication unit 11-3. The measurement unit 11-1 measures the values related to the operation states of the individual components included in the pallet moving mechanism 13, the operation panel 14, and the sensor device 15, respectively. The value related to the operation state of each component measured by the measuring unit 11-1 may include, for example, the number of times of energization, energization time, magnitude of current, temperature, and the like. Further, all of the values relating to the operation status may be measured, or one of them may be measured.

  The storage unit 11-2 stores a first table that stores a value related to the operation status of each component measured by the measurement unit 11-1, and a second table that stores a predetermined threshold value for the value related to the operation status of each component. Is stored. The communication unit 11-3 displays the value on the display unit 114-1 of the operation panel 14 when the value related to the operation status of each component stored in the first table is equal to or greater than the threshold value stored in the second table. The information to be transmitted is transmitted to the operation panel 14.

  The processing of the control device 11 having such a configuration will be described below with reference to a configuration example of a table included in the storage unit 11-2 illustrated in FIGS. FIGS. 4 to 6 respectively illustrate tables that store values relating to the operating states of the motors 1 to 3 included in the pallet moving mechanism 13 among a plurality of components provided in the parking device 100.

  First, the first table included in the storage unit 11-2 will be described with reference to FIG. FIG. 4A shows, as an example, a first table storing the number of energizations and energization times of the plurality of motors 1 to 3, and FIG. 4B shows, as an example, the energization of the plurality of motors 1 to 3. 5 shows a table for storing a start date and time and an energization end date and time.

  As shown in FIG. 4A, when the first table stores the number of times of energization and the energization time, the first table measures from the start of use of each component measured by the measuring unit 11-1 of the control device 11 to the present. The information of the integrated number of times of power supply and the integrated time of power supply is stored.

  Therefore, the measurement unit 11-1 first measures the energization start date and time and the energization end date and time of the motors 1 to 3 using an energization counter or an energization time meter arranged inside the pallet moving mechanism 13. The energization time per operation calculated from the energization start date and time and the energization end date and time is stored in the table shown in FIG. Next, in the first table shown in FIG. 4A, the measuring unit 11-1 integrates the energizing time per operation shown in FIG. 4B with the energizing time from the start of use to the previous time. Thus, the total energizing time and the total number of energizing times are stored.

  FIG. 5 illustrates, as an example, a second table that stores information indicating the number of times of energization of the plurality of motors 1 to 3 and a threshold value of the energization time. In the second table, a predetermined threshold is set in advance. The threshold value relating to the operation status of each component is a value set as a guide for notifying a user of the replacement time and performance status of each component, and may be a value arbitrarily defined by an administrator or the like.

  As described above, the information on the value and the threshold value regarding the operation status of each component is stored in each table stored in the storage unit 11-2. By using such information, the number of energization times and energization time stored in the first table shown in FIG. 4A are replaced by the number of energization times and energization time stored in the second table shown in FIG. When the threshold value is exceeded, it is possible to predict the performance degradation and the component life of the component. Here, a configuration in which both the number of times of energization and the time of energization are measured and stored will be described as an example, but a configuration in which one of the number of times of energization and the time of energization is measured and stored is provided. Is also good.

  Next, referring to FIG. 6, an example will be described in which not only the number of times of energization and the energizing time but also, for example, a case where temperature is measured from a temperature sensor disposed inside each component. FIG. 6A shows a first table for storing information on the measurement temperature and the measurement date and time measured by the measurement unit 11-1, and FIG. 6B is arbitrarily set by an administrator or the like. FIG. 6C illustrates a second table that stores a temperature threshold, and FIG. 6C illustrates a table that stores the number of times the measured temperature measured by the measurement unit 11-1 exceeds the threshold.

  The measurement unit 11-1 acquires temperature information from the temperature sensors arranged inside the motors 1 to 3, and stores the measured temperature and the measurement date and time at the time in the first table shown in FIG. Store. In such a temperature measurement, the measurement process may be automatically started when each of the motors 1 to 3 is energized, or the measurement process is started periodically at a preset time. It may be something.

  The measurement unit 11-1 determines whether the measured temperature stored in the first table shown in FIG. 6A is equal to or higher than the temperature threshold stored in the second table shown in FIG. 6B. May accumulate the number of times and store the number of times exceeding the threshold value in the table shown in FIG. By storing such information in the storage unit 11-2, the degree of deterioration according to the temperature of each of the motors 1 to 3 is diagnosed based on the number of times that the temperature inside each of the motors 1 to 3 exceeds the threshold value. It is also possible to do.

  As described above, according to the control device 11, the measurement unit 11-1 uses the pallet moving mechanism 13, the operation panel 14, and the number of energization times and the energization time of each component included in the sensor device 15, and the values related to the operation status such as the temperature. By comparing the measured value stored in the first table with the threshold value stored in the second table, if the threshold value is exceeded, the performance degradation of each component and the component life Can be predicted.

  4 to 6, the plurality of motors 1 to 3 included in the pallet moving mechanism 13 have been described as an example. However, driving components such as a plurality of rollers and bearings included in the pallet moving mechanism 13 and sensors The same measurement can be performed for components such as a plurality of photoelectric sensors and a plurality of limit switches included in the device 15 and push buttons, operation key switches, and operation key cylinders included in the operation panel 14.

  Based on the values related to the operation status of each part measured in this way, the control device 11 diagnoses the performance state of each part, and notifies the user of the maintenance time and repair method of each part, and the like. Hereinafter, the predictive maintenance processing of each component provided in the parking device 100 by the control device 11 according to an embodiment of the present invention will be described in detail with reference to FIG.

  FIG. 7 is a flowchart illustrating a flow of a process performed by the control device 11 according to the embodiment of the present invention. As shown in FIG. 7, the control device 11 first measures a value related to an operation state of each component (S310). In S310, the measurement unit 11-1 of the control device 11 calculates the number of times of current supply and the current supply time of each component of the pallet moving mechanism 13, the operation panel 14, and the sensor device 15, the temperature, and the value relating to the operation status such as the magnitude of the current. Is measured and stored in a table stored in the storage unit 11-2.

  Next, the control device 11 executes comparison data processing (S320). In S320, the measurement unit 11-1 of the control device 11 sets a value that can be compared with the threshold value stored in the second table stored in the storage unit 11-2 for the value related to the operation status of each component measured in S310. If it is, it is stored in the first table stored in the storage unit 11-2. If the value related to the operation status of each component measured in S310 is not a value that can be compared with the threshold value stored in the second table, the threshold value stored in the second table based on the measured value is used. Is calculated again, and the calculated value is stored in the first table stored in the storage unit 11-2.

  Next, the communication unit 11-3 of the control device 11 compares the value related to the operation status of each component stored in the first table with the threshold value stored in the second table, and determines that the value related to the operation status is It is determined whether the value is equal to or larger than the threshold (S330). In S330, when it is determined that the value related to the operation status is equal to or greater than the threshold, the communication unit 11-3 transmits the display data displayed on the display unit 114-1 of the operation panel 14 to the operation panel 14 (S340). ).

  At this time, the display data transmitted from the communication unit 11-3 may be information stored in a table stored in the storage unit 11-2 according to individual components and individual operating conditions. The display data is information stored in advance in a table stored in the storage unit 11-2, the content that the administrator or the like desires to notify the user via the display unit 114-1 of the operation panel 14. Is also good. For example, the display data may be a notification of a replacement of the part, a guidance of a repair method, or the like, which is notified to the user. Thereby, the communication unit 11-3 can select display data corresponding to each component and each operation state from the table stored in the storage unit 11-2 and transmit the display data to the operation panel 14.

  When the control device 11 is communicably connected to an administrator terminal or the like via a network, the communication unit 11-3 stores the display data stored in the table stored in the storage unit 11-2. May be transmitted to the administrator terminal together with the operation panel 14. Thereby, the manager or the like can also recognize the information on the operation status of each component of the parking device 100 while being at a remote place.

  Although not shown in FIG. 7, in S340, the communication unit 11-3 stores the information in the table stored in the storage unit 11-2 according to the information input to the input unit 114-2 of the operation panel 14. It may be determined whether or not the display data is transmitted to the operation panel 14. For example, when the information input to the input unit 114-2 of the operation panel 14 includes information that the user input to the input unit 114-2 of the operation panel 14 is not the target person to notify the contents of the display data. Alternatively, the communication unit 11-3 may perform a process of not transmitting display data to the operation panel 14.

  In S340 illustrated in FIG. 7, the processing ends when the communication unit 11-3 transmits the display data to the operation panel 14. Also, in S320, the process ends even when it is determined that the value related to the operation status is not equal to or larger than the threshold.

  As described above, according to the control device 11 included in the parking device 100 according to the embodiment of the present invention, when the measured value of the operation state of each component is equal to or greater than the preset threshold, the user is notified to the user. Thus, it is possible to notify the user of the replacement suggestion and the guidance of the repair method by displaying the guidance via the display unit 114-1 of the operation panel 14.

  Therefore, according to the parking device 100 according to an embodiment of the present invention, the performance of each component can be measured before the occurrence of a failure by measuring the value of the operation status such as the number of times of energization and the energization time of each component. Since the situation can be diagnosed and notified to the user, it is possible to prevent a failure or trouble in the parking device and to ensure the safety of the user.
