The display device 17 is a CRT (Cathode-ray Tube), LCD (Liquid Crystal Display), or the like, and displays various information under the control of the CPU 12.
[0017]
The storage units 13, 18 and 19 are HDDs (Hard Disk Drives), and the storage unit 13 stores a control program group such as an OS (Operating System) and an application for creating a repair plan. The storage unit 18 stores acoustic state data DA, and the storage unit 19 stores modification content data DK that specifies the modification content for each modification element. The application program is stored from a recording medium such as a floppy disk (registered commercial law) or a compact disk (registered trademark) such as a CD-R or CD-ROM in which the application program for supporting the creation of the above-mentioned repair plan is recorded. After installing in the unit 13, it may be read and executed / functioned by the CPU 12.

The
[0021]
(1.3) Operation of the embodiment
Next, operation | movement of the assistance apparatus 10 which concerns on this embodiment is demonstrated.
In the support apparatus 10 as a computer, when an operator gives an instruction to execute an application for supporting the creation of a repair plan in the present invention, the CPU 12 reads the application program from the storage unit 13 and performs the following processing. To function and execute. FIG. 5 is a flowchart showing a main routine in such a case.
First, the CPU 12 displays a main menu screen on the display device 17 (step S1), and the operator performs a desired process from “input of acoustic state data” and “comparison verification” which are processes of the present embodiment. Prompt to select. For convenience of explanation, a mouse cursor is displayed on the main menu screen and various screens described below, and the mouse cursor is moved to a display area corresponding to a desired process and the mouse is operated (clicked) to perform a desired process. It is assumed that the selection operation is performed. However, it goes without saying that the operation of the keyboard or other operation elements may be performed.
[0022]
Next, the CPU 12 determines whether or not a selection operation has been performed (step S2). When this determination result is “NO”, the CPU 12 repeats the same determination. On the other hand, if it is determined that the selection operation has been performed, the determination result of step S2 is “YES”, and the process of the CPU 12 proceeds to step S3. In step S <b> 3, the CPU 12 determines whether the selected process is an “acoustic state data input” process.
[0023]
If the process selected in the determination in step S3 is the “input acoustic state data” process, the determination result is “YES”, and the CPU 12 advances the process to step S4 to input the acoustic state data DA input screen. Is displayed. This input screen is a screen on which the facility overview, the acoustic state at the time of completion of the acoustic facility, the current acoustic state at each time point in the future described in the acoustic check sheet are entered.
[0024]
FIG. 6 is a diagram showing the first half of an example of this input screen, and FIG. 7 is a diagram showing the second half of the input screen. The input screen can be scrolled by changing the area that the CPU 12 displays on the display device 17 in accordance with the operation of a scroll button (not shown).
As shown in FIG. 6 and FIG. 7, in this input screen, the same items as the acoustic evaluation items in the acoustic check sheet are described for each of the facility overview, the completion time, and the current and future acoustic states. An input box, a check box, and the like are displayed to prompt the operator to input an acoustic state. It should be noted that character input to the input box and check of the check box are performed using a keyboard and a mouse as in a conventional PC.
[0025]
As shown in the figure, on this input screen, for acoustic evaluation items in which the types of selection candidates such as the purpose of the hall and the stage / audience format are known in advance, these selection candidates are displayed in association with check boxes. An acoustic state input (selection) is accepted by checking the box. Thereby, the operator can input the acoustic state more easily than performing the text input, and on the support device 10 side, the number is much less than the method of determining the acoustic state input from the text. It can be determined by the processing burden.
In addition, as shown in the figure, among the input contents of the input screen at the time of completion of this input screen and the current and future acoustic status, the current acoustic status is for inputting whether the current status is satisfactory for a predetermined item. A check box is provided. Specifically, regarding the sound, a check box for selecting the current evaluation from “appropriate”, “long”, and “short” is displayed, and regarding the quietness of the room, “quiet” and “quiet” Displays a check box for selecting the current evaluation from “not”.
Further, on this input screen, an operation button B1 for instructing “save”, an operation button B2 for instructing “display of acoustic state analysis sheet”, and an operation button B3 for instructing “return to main” are displayed.
[0026]
When the input screen is displayed, the CPU 12 advances the process to step S5 to determine whether any of the operation buttons B1 to B3 has been operated. If the determination result in step S5 is “NO”, the CPU 12 repeats the same determination. On the other hand, if it is determined that the operation has been performed, the determination result in step S5 is “YES”, and the process proceeds to step S6. In this step S6, the CPU 12 determines whether or not the operated operation button is the operation button B1, and if the determination result is “YES”, the process proceeds to step S7, and the data input to this input screen is displayed. It is stored in the storage unit 18 as acoustic state data DA. In this case, the CPU 12 requests the operator to input a file name, and stores the input file name in association with the acoustic state data DA.
[0027]
On the other hand, if the determination result in step S6 is “NO”, the CPU 12 advances the process to step S8, determines whether or not the operated operation button is the operation button B2, and if the determination result is “YES”. Advances the process to step S9. In step S <b> 9, the CPU 12 performs a sound state analysis sheet display process based on the sound state data DA input on the input screen.
[0028]
FIG. 8 is a diagram illustrating an example of the acoustic state analysis sheet. As shown in the figure, this acoustic state analysis sheet is a summary of the acoustic state input on the input screen in an easy-to-see form, and the CPU 12 uses the check box to check the characters and numerical values input to the input box. The selected acoustic evaluations are rearranged and displayed in a predetermined format. At this time, an operation button (not shown) for performing a print instruction is displayed on the display screen, and the description of the operation is omitted. By operating this operation button, the acoustic state analysis is performed. The sheet can be printed from the printer. Further, an operation button (not shown) for returning to the main menu is also displayed on the display screen, and it is possible to return to the main menu (step S1 processing).
[0029]
On the other hand, if the determination result in step S8 is “NO”, it is determined that the operation button B3 has been operated, so the CPU 12 proceeds to step S1 and displays the main menu screen. Thereby, it is possible to return the processing from the state where the input screen is displayed to the display of the first main menu screen.
[0030]
Next, when it is determined that the process selected in the determination in step S3 is the “comparison verification” process, the CPU 12 executes a comparison verification process of the acoustic state data DA (step S10). FIG. 9 is a flowchart showing a comparison verification processing routine.
First, the CPU 12 reads out the file name of the acoustic state data DA stored in the storage unit 18 and displays it on the display device 17 (step S21), and prompts the operator to select a file name for comparison verification. .
[0031]
Next, the CPU 12 determines whether or not a selection operation has been performed (step S22). If the determination result is “NO”, the CPU 12 repeats the same determination. On the other hand, if it is determined that the selection operation has been performed, the determination result in step S22 is "YES" is determined, the process proceeds to step S23, the acoustic evaluation data DA of the selected file name is read out and stored in the RAM 15, and then the process proceeds to step S24.
[0032]
In step S24, the CPU 12 compares the acoustic state at the time of completion with the current acoustic state for each acoustic evaluation item in the acoustic state data DA stored in the RAM 15, and repairs corresponding to aging and aging. Perform element extraction. As an example, if the use of the hall has changed from the time of completion to the present, that fact is extracted as a renovation element, and if the reverberation value (the value of reverberation time) has changed, that fact is the refurbishment element. Extract as In other words, the difference between the acoustic evaluation at the time of completion and the current acoustic evaluation is considered to be due to the effects of secular change and aging. Refurbishment elements can be extracted accurately.
[0033]
Next, when the CPU 12 has extracted the modification elements for all the acoustic evaluation items, the CPU 12 proceeds to step S25 and refers to the modification content data DK1 stored in the storage unit 19 based on the modification elements for each acoustic evaluation item. The contents of modification associated with each modification element are read out and stored in the RAM 15.
[0034]
Then, when the CPU 12 reads out the modification contents associated with all the extracted modification elements and stores them in the RAM 15, the process proceeds to step S26. In step S <b> 26, the CPU 12 compares the current acoustic state and the future acoustic state for each acoustic evaluation item in the acoustic state data DA stored in the RAM 15, and extracts a repair element corresponding to the deficient portion. I do. As an example, if the use of the hall has changed between the present and the future, that fact is extracted as a modification element, and if the reverberation value (the value of reverberation time) has changed, that fact is used as the modification element. Extract. That is, since the difference between the current acoustic evaluation and the future acoustic evaluation can be considered as an insufficient acoustic function, the insufficient acoustic function can be accurately extracted by extracting this difference.
[0035]
However, for example, if the sound is described as appropriate, that is, if the check box indicating that sound is appropriate is checked on the input screen (see FIG. 6), the value of the sound has changed. However, it is not extracted as a renovation element. In other words, among the current acoustic states, those that are satisfied by the sound facility manager or the like can be determined not to be an insufficient acoustic function, so even if a difference occurs, it is not extracted as a repair element.
[0036]
Next, when the CPU 12 has extracted the modification elements for all the acoustic evaluation items, the CPU 12 proceeds to step S27 and refers to the modification content data DK2 stored in the storage unit 19 based on the modification elements for each acoustic evaluation item. The contents of modification associated with each modification element are read out and stored in the RAM 15. As described above, the repair content data DK2 describes the repair content for the purpose of dealing with the shortage of the respective repair elements. Therefore, it is possible to specify appropriate repair content.
[0037]
Further, when the CPU 12 reads out the modification contents associated with all the extracted modification elements and stores them in the RAM 15, the process proceeds to step S28. In step S <b> 28, the CPU 12 extracts a repair element from the acoustic state data DA stored in the RAM 15 based only on the future acoustic state, and proceeds to step S <b> 29. In step S29, the CPU 12 refers to the modification content data DK3 stored in the storage unit 19 based on the extracted modification element, reads the modification content associated with each modification element, and stores it in the RAM 15. As described above, since the repair content data DK3 describes the repair content for each repair element in the future, it is possible to identify the appropriate repair content for the future based on the future acoustic state. It becomes.
[0038]
Then, when the CPU 12 reads out the modification contents associated with all the extracted modification elements and stores them in the RAM 15, the process proceeds to step S30. In step S <b> 30, the CPU 12 displays the modification plan analysis sheet on the display device 17 by rearranging the contents of the modification stored in the RAM 15 and displaying them in a predetermined format.
[0039]
FIG. 10 is a diagram illustrating an example of the repair plan analysis sheet. As shown in the figure, this renovation plan analysis sheet has been extracted into categories such as countermeasures for aging / aging, countermeasures for insufficient acoustic functions, and renovation plans / facility maintenance for the future. It is the table | surface which described the corresponding renovation content for every acoustic evaluation item.
Therefore, this repair plan analysis sheet allows the operator to know the contents of the repair from the viewpoints of countermeasures for aging / aging, countermeasures for insufficient acoustic functions, and repair plans / facility maintenance for the future. it can.
[0040]
Also in this case, an operation button (not shown) for performing a print instruction is displayed on the display screen, and this function / usage analysis sheet is printed from the printer by operating this operation button. In addition, an operation button (not shown) for returning to the main menu is displayed, and it is possible to return to the main menu (step S1 processing). Thereby, a repair plan creator or the like can create a repair plan with reference to the repair plan analysis sheet.
[0041]
As described above, the support device 10 according to the present embodiment, based on the comparison result between the acoustic state at the completion of the acoustic facility for which the repair plan is to be created and the current acoustic state, the modification content to be displayed from the modification content data DK1. Therefore, it is possible to display the exact renovation contents against aging and aging.
Further, since the support device 10 selects the modification content to be displayed from the modification content data DK2 based on the comparison result between the current acoustic state and the future acoustic state of the acoustic facility for which the modification plan is to be created, the lack of sound It is possible to display the exact contents of modification for the function. In this case, reference is made to information indicating whether or not each acoustic evaluation item included in the current acoustic state of the acoustic state data DA is satisfactory, and no acoustic elements are extracted for satisfactory acoustic evaluation items. It is possible to remove equipment that is deemed unnecessary from the scope of repair.
[0042]
In addition, the support device 10 selects the content to be displayed from the repair content data DK3 based on the future acoustic state of the acoustic facility for which the repair plan is to be created. Therefore, the support device 10 is suitable for future repair plans and facility maintenance. The contents of the repair can be displayed accurately.
As a result, by using the repair plan analysis sheet displayed by the support device 10, there is almost no need to manually perform repair element extraction work or repair content extraction work such as a repair plan creator. Can be useful.
[0043]
(2) Second embodiment
The modification plan creation support device (hereinafter referred to as support device) 100 according to the second embodiment differs from the support device 10 according to the first embodiment in that the reverberation time as an objective reference and the objective The air conditioning noise, which is a standard, is calculated and further included in the content of the above-described repair plan analysis sheet.
[0044]
That is, in this support apparatus 100, statistical data DT obtained from a statistical graph showing the relationship between the volume of the concert hall and the multipurpose hall of the 70-90s and the reverberation time (the reverberation time when empty) as shown in FIG. And the statistical data DS obtained from the statistical graph showing the relationship between the opening year and the air conditioning noise as shown in FIG. 12 or FIG. 13 are stored in the storage unit 19, and these statistical data DT and DS are stored in the comparison verification process. Based on this, a process of calculating a reverberation time as an objective reference and an air conditioning noise value as an objective reference for the acoustic facility corresponding to the acoustic state data DA to be compared and verified is further performed.
[0045]
Specifically, a reverberation time as a reference in the case of a concert hall and a multipurpose hall of each age is calculated from the value of the room volume included in the acoustic state data DA and the statistical data DT, and the acoustic state data The standard air conditioning noise value is calculated from the opening year value included in the DA. And in this assistance apparatus 100, these calculated reverberation time and the value of an air-conditioning noise are included and displayed in a repair plan analysis sheet.
[0046]
Thus, the rehabilitation plan analysis sheet displays the reverberation time and the air conditioning noise, which are the objective standards of the acoustic facility indicated by the acoustic state data DA, and for the renovation plan creator and the like, An objective evaluation can be performed by comparison with air conditioning noise. Further, by using the statistical data DTA obtained from the statistical graph shown in FIG. 14 instead of the statistical data DT, an objective reverberation time may be calculated from the number of seats (main personnel).
[0047]
Note that the method for calculating and displaying the reverberation time and the air conditioning noise, which are objective standards, is not limited to the above-described method, and various methods may be applied.
Specifically, data obtained from a well-known graph (see FIG. 15) showing the relationship between the recommended room volume and the optimum reverberation time for each purpose of use is stored in the storage unit 19 and the target acoustic facility is used. You may make it calculate the optimal reverberation time suitable for the objective.
Further, data indicating the relationship between the room type and the allowable value of the room noise (see FIG. 16) is stored in the storage unit 19, and the allowable value of the room noise is displayed based on the type (use) of the target acoustic facility. It may be.
[0048]
If the optimal reverberation time and the permissible value of room noise obtained in this way are included in the renovation plan analysis sheet and displayed, it will be more appropriate for the renovation plan creator to compare the current reverberation time with the air conditioning noise. Evaluation can be made.
[0049]
(3) Supplement
The present invention is not limited to the above-described embodiment, and can be implemented in various aspects. For example, the following modifications are possible.
[0050]
(3.1)
In the above-described embodiment, the case where the contents of the repair are displayed for each of the countermeasures for aging / aging, the countermeasures for the insufficient sound function, and the repair plans / facility maintenance for the future is described. Only the repair contents of any category, for example, only the repair contents for aging / aging, or only the repair contents for the insufficient acoustic function may be specified and displayed.
[0051]
In the case where the support device 10 is configured to display only the contents of repair to aging / aging, the acoustic state data DA only needs to describe the completion and current acoustic state. May store only the repair content data DK1. Further, when the support device 10 is configured to display only the content of the modification to the lacking acoustic function, it is sufficient that only the current and future acoustic states are described in the acoustic state data DA. May store only the modification content data DK2.
