Description

The present invention relates to an elevator car position display device, and is suitable for application to an elevator car position display device capable of displaying the position of a moving car in the elevator car.

Conventionally, the current car position is displayed on a display panel or the like in the elevator car based on the car position information. However, especially in a high-speed elevator, if the car moves to another floor earlier than the update cycle of the car position information, the car position information jumps on the middle floor, and the floor jump of the car position display on the display panel occurs. It could happen. As a result, there is a problem of giving passengers an unfriendly impression and a sense of discomfort.

In response to such a problem, for example, Patent Document 1 discloses a car position display device that complements and displays the missing floor when the car position information of the missing floor is received.

Japanese Unexamined Patent Publication No. 2014-125287

By the way, in general, the image data for displaying the car position on the display panel or the like in the car is stored in the storage device by compressing the image data for each floor in order to reduce the capacity. Therefore, each time the car position of a certain floor is to be displayed, the compressed image data of the floor is read from the storage device, decompressed, and then displayed, which requires a certain amount of processing time. It was a thing. As a result, when the car moves at high speed in a conventional elevator, the time required for the car to pass through the floor is faster than the processing time required for displaying the car position on the passing floor. There was a problem that the position could not be displayed and the floor jump of the car position display occurred.

Then, it is considered that it is difficult to solve the above-mentioned problem of the floor jump of the car position display even with the car position display device disclosed in Patent Document 1. For example, even if an attempt is made to complement display the car position display for a passing floor where a floor jump occurs, there is a possibility that the car position display will not be displayed as a result because the processing time for the complementary display is too long. Further, even if the processing time for the complementary display falls within the transit time, it is assumed that the display time for the complementary display can be secured only for an extremely short time, so that the passenger cannot sufficiently recognize the displayed contents. There was a risk of giving passengers a sense of discomfort.

The present invention has been made in consideration of the above points, and an elevator car position display device capable of preventing the floor jumping of the car position display and suppressing the discomfort of passengers even in a high-speed elevator. I'm trying to make a suggestion.

In order to solve such a problem, the present invention provides the following elevator car position display device that displays the position of a moving car on a display in the car. The car position display device has a speed determination unit that determines a plurality of speed levels based on the speed information of the car, and image data that displays each floor included in the operation range of the car. Based on the image data storage unit stored in a plurality of patterns for each image level corresponding to the speed level of the stage, the position information of the car, and the speed level determined by the speed determination unit, the display is displayed. A display that determines the display content and the image level of the display data to be displayed, reads the image data corresponding to the determined display data from the image data storage unit, and executes data processing necessary for displaying the data on the display. A data determination unit and a display unit that displays the image data after the data processing by the display data determination unit is performed on the display unit are provided. Then, when the image data stored in the image data storage unit corresponds to the display data, the display processing required until the data processing is performed by the display data determination unit and the image data is displayed by the display unit. When the time is different for each image level and the car speed is relatively high, the display processing time at the first image level corresponding to the first determined speed level is determined. One of the features is that it is shorter than the display processing time at the second image level corresponding to the second determined speed level when the car speed is relatively low.

According to the present invention, even in a high-speed elevator, it is possible to prevent the floor jumping of the car position display and suppress the discomfort of passengers.

It is the schematic of the elevator equipped with the car position display device which concerns on one Embodiment of this invention. It is a block diagram which shows the functional structure example of a car position display device. It is a block diagram which shows the hardware configuration example of a car position display device. It is a figure explaining an example of image data for each image level. It is a flowchart which shows an example of the processing procedure of a car position display processing. It is a figure for demonstrating the change of the speed level with the movement of a car. It is a figure which shows the specific example of the change of the car position display by a car position display process.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) Overall Configuration of Elevator FIG. 1 is a schematic view of an elevator equipped with a car position display device according to an embodiment of the present invention. Although FIG. 1 shows an overall view of a general hanging type elevator as the elevator 1, the elevator to which the car position display device 10 according to the present embodiment can be applied is The structure is not limited to the elevator 1 as long as it has a structure capable of detecting the moving speed (car speed) and the height position (car position) of the car with a predetermined accuracy.

As shown in FIG. 1, the elevator 1 is a hoisting machine 3 installed above the hoistway 2 and equipped with a motor (not shown) for driving the elevator 1, and a rope hung on the hoisting machine 3. A car 5 suspended at one end of a rope 4, a counterweight 6 suspended at the end opposite to the car 5 of the rope 4 to balance the car 5, and a control panel 7 for controlling the operation of the elevator 1. And.

In addition to the car position display device 10 having a function of displaying the car position by the number of floors (car position display function), the car 5 is a car operation panel 8 in which passengers can specify the destination floor, open / close the door, and the like. Etc. are provided. The car position display device 10 and the car operation panel 8 are communicably connected to the control panel 7 and the like. The detailed configuration of the car position display device 10 will be described later.

Further, a car position detecting device 11 for detecting the car position is attached to the car 5. In the present embodiment, the car position detecting device 11 has an accuracy capable of detecting the car position at least at each floor and an intermediate point between the floors, and the detection result (car position information) is directly or the control panel. It is transmitted to the car position display device 10 via 7.

Specific examples of the car position detecting device 11 include a positive detector. The positive detector is a known detector used for detecting the car position, and can detect the car position based on the transmission and reception of light to a plurality of shielding plates installed at predetermined positions in the hoistway 2. In addition, the car position can be detected by a motor encoder (not shown).

The control panel 7 monitors the state of the elevator 1 based on the information of each part of the elevator 1, performs various arithmetic processes, and controls the movement of the car 5 and the opening and closing of the door in the elevator 1. .. For example, the control panel 7 can realize the function as the speed detection device 12 by detecting the moving speed (car speed) of the car 5 based on the rotation speed of the motor of the hoisting machine 3. The speed detection device 12 in the present embodiment does not necessarily have to be realized by the control panel 7. For example, a speed sensor may be attached to the car 5 to detect the car speed. Then, the detection result (speed information) by the speed detection device 12 is transmitted to the car position display device 10.

(2) Configuration of Car Position Display Device The configuration of the car position display device 10 will be described in detail.

FIG. 2 is a block diagram showing a functional configuration example of the car position display device. As shown in FIG. 2, the car position display device 10 according to the present embodiment is a device communicably connected to the car position detection device 11 and the speed detection device 12, and is a speed determination unit 110 and display data. It includes a determination unit 120, an image data storage unit 130, and a display unit 140.

Here, FIG. 3 is a block diagram showing a hardware configuration example of the car position display device. The car position display device 10 can be realized by a hardware configuration in which a liquid crystal CPI (Car Position Indicator) 26 is connected to the microcomputer 21, for example, as shown in FIG. The microcomputer 21 has a CPU (Central Processing Unit) 22, a ROM (Read Only Memory) 23, a RAM (Random Access Memory) 24, and an I / O (Input / Output) 25. As shown in FIG. 3, an external memory 27 may be connected to the microcomputer 21 via the I / O 25. Further, the liquid crystal CPI 26 is an example of a display panel for displaying the car position display, and is installed at a position where the display screen can be visually recognized by passengers in the car 15. The liquid crystal CPI may be replaced by another display.

When the car position display device 10 has the hardware configuration shown in FIG. 3, the speed determination unit 110 and the display data determination unit 120 are realized by the CPU 22 reading the program stored in the ROM 23 into the RAM 24 and executing the program. Further, the image data storage unit 130 is realized by the RAM 24 or the external memory 27, and the display unit 140 is realized by the liquid crystal CPI 26.

The hardware configuration of the car position display device 10 according to the present embodiment is not limited to the example of FIG. 3, and each functional configuration of the car position display device 10 is realized by another configuration of the elevator 1. It may be what is done. For example, the car position display device 10 may be realized by integrating the functions into the car operation panel 8. Further, a part of the car position display device 10 (for example, a speed determination unit 110, a display data determination unit 120, or an image data storage unit 130) may be realized by the control panel 7.

Returning to FIG. 2, each functional configuration of the car position display device 10 will be described.

The speed determination unit 110 has a function of determining the speed level of the car speed based on the speed information input from the speed detection device 12. The memory (for example, RAM 24) of the car position display device 10 stores threshold values for speed levels in a plurality of stages, and the speed determination unit 110 compares the speed information with the above threshold values to obtain the speed level of the car speed. To judge.

In this description, as an example, the speed level used as standard is set to "level A", and the time of stop or low speed operation corresponds to level A. Then, it is assumed that "level B" corresponding to medium-speed operation and "level C" corresponding to high-speed operation are prepared as speed levels corresponding to the speed range higher than level A. Further, the threshold value on the boundary between "level A" and "level B" is defined as "threshold value α", and the threshold value on the boundary between "level B" and "level C" is defined as "threshold value β". By determining the speed level by the speed determination unit 110 based on such a threshold value, when the car 5 moves from the departure floor to the destination floor at high speed, the speed level is between "level A" and "level C". It will change. The relationship between the car speed, the threshold value, and the speed level is specifically shown in FIG. 6, which will be described later. Although the details will be described later, the speed level levels A to C correspond to the image level levels A to C.

The display data determination unit 120 displays image data (display) displayed on the display unit 140 (liquid crystal CPI 26) based on the car position information input from the car position detection device 11 and the speed level determined by the speed determination unit 110. It has a function to determine the data). More specifically, the display data determination unit 120 determines the floor to be displayed on the liquid crystal CPI 26 and the image level thereof. Further, the display data determination unit 120 reads the image data corresponding to the display data from the image data storage unit 130, decompresses the image data, and decompresses the image data corresponding to the display data as a process necessary for displaying the determined display data on the display unit 140. Output (transfer) to.

The image data storage unit 130 stores image data for each floor that displays the car position by the number of floors for each speed level. In other words, in the image data storage unit 130, image data indicating each floor (each floor included in the operation range of the car 5) that may be displayed in the car position is an image corresponding to each floor and the speed level. It is stored for each level. Each of these image data is compressed and stored in order to reduce the capacity, and is decompressed when read by the display data determination unit 120. FIG. 4, which will be described later, shows specific examples of image data for each image level.

In the present embodiment, the image data corresponding to the speed level has the following features. That is, as the image data corresponding to the speed level at which the car speed is relatively low, fine pixel image data (in other words, image data having a large data size) is prepared, and the image data corresponding to the speed level at which the car speed is relatively high is prepared. Is prepared with coarse-pixel image data (in other words, image data with a small data size). As is generally known, image data with coarse pixels (small data size) requires more processing time for reading, decompressing, and transferring than image data with fine pixels (large data size). It will be a short time. Therefore, in the present embodiment, when the car speed is high, image data that can be read, decompressed, and transferred in a relatively short time is selected as display data.

Further, the image data storage unit 130 stores image data for each floor and each image level as independent data. By adopting such an image data storage method, a predetermined floor can be stored. When attempting to display the car position, the display data determination unit 120 only needs to read, decompress, and transfer the image data of the floor concerned, so that an excessive processing load can be suppressed and the processing time is shortened. You can expect the effect.

The display unit 140 has a function of displaying the decompressed image data (display data) transferred from the display data determination unit 120 on the liquid crystal CPI 26. As described above, when the car speed becomes high, the display data determination unit 120 executes the processing of reading / decompressing / transferring the image data having a short processing time, so that the display unit 140 has a case where the car speed is low. The image data can be displayed on the liquid crystal CPI 26 in a shorter time than that, and as a result, it is possible to prevent the occurrence of floor jumping in the car position display.

FIG. 4 is a diagram illustrating an example of image data for each image level. The image data 131 to 133 exemplified in FIG. 4 are all image data representing the number "5", and are used to indicate the "fifth floor" in the car position display. Of these, the image data 131 is image data corresponding to the speed level of level A, and the image level is referred to as "level A". Similarly, the image data 132 is image data corresponding to the speed level of level B, and the image level is referred to as "level B". Further, the image data 133 is image data corresponding to the speed level of level C, and the image level is referred to as "level C".

Comparing the image data 131 to 133, the level A image data 131 has the finest pixels (the number of pixels is large), so that when displayed on the display unit 140, a good-looking and clear car position display is realized. can do. However, since the image data 131 of level A has fine pixels, the data size is relatively large, and the processing time until it is displayed is the longest. On the other hand, since the level C image data 133 has the coarsest pixels (the number of pixels is small), the appearance when displayed on the display unit 140 is inferior to that of other image data. However, since the pixels are coarse, the data size is relatively small, and the processing time until display on the display unit 140 is the shortest. The level B image data 132 has an intermediate feature between the level A and the level C. The number of pixels and data size of the image data at each image level can be arbitrarily set based on the environment of the elevator 1 and the processing performance of the car position display device 10 within the range having the above-mentioned characteristics. .. For example, it is conceivable to set the number of pixels of the level B and level C image data to be 80% and 70%, respectively, with respect to the number of pixels of the level A image data.

In the example of FIG. 4, the number of pixels is different as a feature of the image data for each image level corresponding to a plurality of speed levels, but the feature of the image data for each image level is limited to this in the present embodiment. It suffices if the processing time required for reading, decompressing, and transferring can be different. For example, the data size of the image data may be different for each image level by changing parameters other than the number of pixels related to image quality.

(3) Car position display processing FIG. 5 is a flowchart showing an example of a processing procedure of the car position display processing. The car position display process executed by the car position display device 10 applied to the elevator 1 will be described with reference to FIG.

First, as an initial operation such as when the power of the elevator 1 is turned on, the display data determination unit 120 performs an initial display process on the display unit 140 (step S11). Specifically, based on the car position information obtained from the car position detection device 11, level A image data for displaying the current car position is determined as display data, and the image data is read out from the image data storage unit 130. , Decompress and output (transfer) to the display unit 140. Supplementing with the above-mentioned contents, the image data of the level A is the image data corresponding to the speed level of the level A used as standard.

Next, the display data determination unit 120 refers to the car position information obtained from the car position detection device 11 and determines whether or not there is a change in the floor of the car 5 (step S12). If there is a change in the floor in step S12 (YES in step S12), it is necessary to display the car position of the changed floor, so the processes after step S13 are performed. On the other hand, if there is no change in the floor in step S12 (NO in step S12), the process of step S12 is executed again when the next car position information is obtained.

Here, the car position detecting device 11 in the present embodiment has an accuracy that can detect a change in the car position at each floor and an intermediate point between the floors. Specifically, for example, when the car position on the second floor is detected, the car position information of "2.0" is acquired, and when the car position at the intermediate point between the second floor and the third floor is detected, "2. It is assumed that the car position information of "5" is acquired. Then, when the acquired car position information is from "above the intermediate point between the predetermined floor and the floor directly below" to less than "the intermediate point between the predetermined floor and the floor directly above", the display data determination unit 120 determines the predetermined position. The floor is judged to be the floor of the car 5. Specifically, when it is assumed that the stoptable floor of the elevator 1 is the first floor or higher, the display data determination unit 120 determines the car when the car position information is "1.0" or more and less than "1.5". It is judged that the floor of the car 5 is "1", and when the car position information is "1.5" or more and less than "2.5", it is judged that the floor of the car 5 is "2" (hereinafter). The same applies to the upper floors). Based on the floor determination of the car 5, the display data determination unit 120 can determine in step S12 whether or not the floor has changed.

When it is determined in step S12 that the floor has changed, the display data determination unit 120 determines the speed level with respect to the car speed (v) obtained from the speed detection device 12 (step S13).

Here, the determination of the speed level with respect to the car speed v in step S13 will be described in detail with reference to specific examples.

FIG. 6 is a diagram for explaining a change in speed level as the car moves. In FIG. 6, the solid line shows an example of the change in the car speed v from the start of the car 5 movement from the departure floor (x0) to the arrival at the destination floor (x7) and the stop. As shown in FIG. 6, in the elevator 1, the car speed v is gradually increased within a range not exceeding a predetermined acceleration for a while (x0 to x3) immediately after the start of movement of the car 5. Then, after the car speed v reaches the specified upper limit speed (v1), the upper limit of the car 5 is up to a point (x3 to x4) where the car can be stopped on the destination floor within a range not exceeding the predetermined deceleration. Operate at speed. After that, the car speed v is gradually lowered (x4 to x7) within a range in which a predetermined deceleration cannot be set, and the car is stopped at the destination floor.

Then, in the movement of the car 5 as described above, the car speed v can be classified into speed levels A to C based on the threshold values α and β. Specifically, when the car speed v is a low speed less than the threshold value α (v <threshold value α), the speed level is determined to be level A. Further, when the car speed v is a medium speed of the threshold value α or more and less than the threshold value β (threshold value α ≦ v <threshold value β), the speed level is determined to be level B. When the car speed v is higher than the threshold value β (v ≧ threshold value β), the speed level is determined to be level C. As a result, as shown in FIG. 6, the speed level becomes level A in the sections of x0 to x1 and x6 to x7 during low-speed operation, and the speed level becomes level A in the sections of x1 to x2 and x5 to x6 during medium-speed operation. Is level B, and the speed level is level C in the section of x2 to x5 during high-speed operation including the upper limit speed.

As described above, in the determination of step S13 by the display data determination unit 120, when the relationship of "v <threshold value α" is established, it is determined that the speed level is level A, and at this time, step S14 is performed. move on. Further, when the relationship of "threshold value α ≦ v <threshold value β" is established, it is determined that the speed level is level B, and at this time, the process proceeds to step S15. Further, when the relationship of "v ≥ threshold value β" is established, it is determined that the speed level is level C, and at this time, the process proceeds to step S16.

Then, in steps S14 to S16, the display data determination unit 120 determines the image data representing the changed floor at the image level corresponding to the speed level determined in step S13 as the display data, and sets the corresponding image data. It is read from the image data storage unit 130 and decompressed.

Specifically, for example, assuming that the floor after the change is the "fifth floor", in step S14 where the speed level is determined to be level A, the display data determination unit 120 displays the car position of the "fifth floor". The level A image data (image data 131 in FIG. 4) is determined as display data, and the image data 131 is read from the image data storage unit 130 and decompressed. Further, in step S15 in which the speed level is determined to be level B, the display data determination unit 120 determines the level B image data (image data 132 in FIG. 4) for displaying the car position of the “fifth floor” as the display data. Then, the image data 132 is read from the image data storage unit 130 and decompressed. Further, in step S16 in which the speed level is determined to be level C, the display data determination unit 120 determines the level C image data (image data 133 in FIG. 4) for displaying the car position of the “fifth floor” as the display data. Then, the image data 133 is read from the image data storage unit 130 and decompressed. As described above with reference to FIG. 4, the image data 131 to 133 at each image level have different pixels (data size), and the image data 132 is larger than the image data 131 and the image data 133 is higher than the image data 132. The processing time required for reading and decompressing is shorter.

After that, the display data determination unit 120 transfers the image data (display data) decompressed in steps S14 to S16 to the display unit 140 at a predetermined communication cycle (for example, 80 ms) according to the specifications of the car position display device 10. As a result, the changed floor is displayed on the liquid crystal CPI 26, and the car position display is updated (step S17).

Then, after step S17, the process returns to step S12, and the processes of steps S13 to S17 are repeated according to the change in the car position (floor).

By performing the car position display processing as described above, when the car 5 of the elevator 1 moves at high speed and the car speed is low (speed level of level A), the image data of level A having the largest data size When the car speed becomes medium speed (level B speed level), the car position is displayed using the image data of level B, which has a smaller data size than level A, and the car is displayed. When the speed becomes high (speed level of level C), the car position can be displayed using the image data of level C having a smaller data size.

FIG. 7 is a diagram showing a specific example of a change in the car position display due to the car position display process. In FIG. 7, when the car 5 moves upward from the first floor, the change in the actual car position with the passage of time is represented by a thick broken line, and the change in the car position display with the passage of time is represented by a thick solid line. ing. Further, in the lower part of FIG. 7, the value of the car position information acquired by the car position detecting device 11 at each timing and a specific image example of the car position display displayed on the display unit 140 (liquid crystal CPI 26) are shown. Has been done. Further, x0 to x2 represented on the vertical axis of FIG. 7 correspond to x0 to x2 described with reference to FIG. That is, the speed level of the car speed is level A between x0 and x1, level B between x1 and x2, and level C after x2.

The change in the car position display shown in FIG. 7 will be briefly described with reference to the processing procedure of FIG. First, since the car position information is within the range of "1.0 to 1.5" from the time when the car 5 starts moving from the first floor until it reaches the intermediate point with the second floor, the car 5 The floor judgment of is unchanged as "1st floor". At this time, among the image data representing the "first floor", the image data of level A is used for the car position display (step S11 in FIG. 5). In the example of FIG. 7, as a specific example of the "car position display", an arrow indicating the moving direction of the car 5 is displayed in addition to the number indicating the floor. As described above, in the present embodiment, the display mode of the car position display (display mode of image data) is not particularly limited. As for the display contents other than the floor (arrows in the above example), those corresponding to the image level of the floor may be prepared and redisplayed according to the display change of the floor. If it is not necessary to change the image during the movement of the image, the display at a specific image level (level A in this example) may be continuously displayed.

After that, when the car position information becomes "1.5", the floor of the car 5 is determined to be "second floor", and the display data determination unit 120 updates the display data in order to update the car position display (FIG. 5). Steps S13 to S16) are performed. Since the speed level at this time is still level A, the image data of level A is selected as the display data for update. Then, the display data for update is transferred from the display data determination unit 120 to the display unit 140 in the communication cycle immediately after that, so that the car position display on the liquid crystal CPI 26 is switched to the "second floor" at the timing of time t1. (Step S17 in FIG. 5).

After that, in the same way, every time the car position information detects an intermediate point on each floor, it is determined that the floor has changed and the display data is updated, and the display data for update is displayed in the communication cycle immediately after. It is transferred to the unit 140 (steps S12 to S17 in FIG. 5). The image level of the image data selected as the display data for update corresponds to the speed level at the timing when the display data update process is performed. For example, in the case of the timing when the car position information "3.5" is acquired in FIG. 7, since the speed level is level B, the level B image data for displaying "4th floor" is the display data for update. Is selected as. Further, when the car position information "5.5" is acquired, the speed level is level C, so the level C image data for displaying "6th floor" is selected as the display data for update. To.

According to FIG. 7, when the car 5 moves while increasing the speed, the display time for displaying the car position on each floor is gradually shortened, which roughly corresponds to the actual car position. It turns out that there is. Further, as the display time of the car position display becomes shorter, the image level of the image data selected as the display data changes in the order of level A, level B, and level C, so that the pixels of the display data may gradually become coarse. I understand. By doing so, the data size of the image data having coarse pixels is small, and the processing time required for displaying the car position can be shortened, so that the floor jump of the car position display on the liquid crystal CPI 26 can be prevented. can do.

Specifically, for example, assuming that the elevator 1 is a high-speed elevator having a maximum speed of 1260 m / min (21 m / s), the car 5 passes through the first floor at the maximum speed when the first floor is 3 m. The time is about 0.14 seconds (3/21: 0.143). Therefore, in the case of this specific example, in order to prevent the occurrence of floor jumping, the processing time until the level C image data is read, decompressed, and transferred and displayed on the display unit 140 (liquid crystal CPI 26) is set. It is necessary to adjust the data size and the like of the image data so that it is at least within 0.14 seconds. Furthermore, the display time of the car position display is adjusted so that the processing time is within 0.04 seconds by securing a predetermined time (for example, 0.1 seconds) that allows passengers to recognize the displayed contents. Is preferable.

Further, in the present embodiment, the high level (level B or level C) image data used when the car speed is relatively high has coarse pixels, and therefore looks better than the low level (level A) image data. Inferior in goodness. However, as described above, since the display time of the high-level image data is relatively short, even if the image data having an inferior appearance is displayed in this relatively short time, the passengers can enjoy the convenience of the elevator 1. It is assumed that the impression will be greatly reduced.

Thus, the car position display device 10 according to the present embodiment prevents the occurrence of floor jumps by appropriately adjusting the appearance and the processing time, which are in a trade-off relationship, with respect to the image data used for the car position display. At the same time, the car position of each floor can be displayed based on the actual car position. According to the present embodiment as described above, it can be expected that the effect of suppressing the deterioration of the elevator service is expected without giving the passengers an unfriendly impression or discomfort due to the floor jump. The present embodiment is particularly suitable for application to a high-speed elevator capable of high-speed operation.

The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations. Specifically, for example, the case where three types of speed levels A to C are prepared has been described, but the types of speed levels may be two types or four or more types. In other words, the number of velocity level thresholds is not limited to a specific number. The same applies to the types of image levels. In addition to this, it is possible to add / delete / replace a part of the configuration of the embodiment with another configuration.

Further, each of the above configurations, functions, processing units, processing means and the like may be realized by hardware by designing a part or all of them by, for example, an integrated circuit. Further, each of the above configurations, functions, and the like may be realized by software by the processor interpreting and executing a program that realizes each function. Information such as programs, tables, and files that realize each function can be stored in a memory, a hard disk, a recording device such as an SSD (Solid State Drive), or a recording medium such as an IC card, an SD card, or a DVD.

Further, in the drawings, control lines and information lines are shown as necessary for explanation, and not all control lines and information lines are necessarily shown in the product. In practice it may be considered that almost all configurations are interconnected.
