Summary of the Invention

Problems to be Solved by the Invention

[0004] The design of a building is carried out so as to satisfy various regulations defined in the Building Standards Law and the like. Regulations regarding buildings are defined for each region and are not common. Also, the ways of defining regulations regarding buildings differ from region to region. Furthermore, amendments to regulations regarding buildings are made at various times. For these reasons, designers spend a lot of time in grasping the contents of regulations regarding the design of buildings.

Means for Solving the Problems

[0005] (1) The design support system for solving the above problems is a design support system for supporting the design of a building, comprising a database that stores data in which an administrative area is associated with regulation-related information related to regulations determined by an administrative agency of the administrative area regarding predetermined design matters of the building, a first input unit that receives an input regarding the building site of a target building to be designed, a derivation unit that identifies the administrative area in which the building site of the target building is included and derives the regulation-related information of the identified administrative area from the data, and an output unit that outputs the regulation-related information. According to this configuration, since the regulation-related information is shown when the building site is input, the labor of grasping the regulations determined by each administrative area regarding the predetermined design matters of the building can be reduced.

[0006] (2) In the design support system of (1) above, the regulation-related information includes information regarding the way of regulation of the regulations regarding the predetermined design matters of the building. According to this configuration, the content of the regulations regarding the predetermined design matters of the building can be easily grasped.

[0007] (3) In the design support system of (1) or (2) above, further comprising a second input unit that receives an input of a design value for the predetermined design matter, and a processing unit that outputs a message related to the design value based on the regulation-related information and the design value, wherein the message includes at least one piece of information regarding the appropriateness of the design value and precautions regarding the regulations. According to this configuration, since the user can receive a message regarding the design value, appropriate measures can be taken for the predetermined design matters of the target building.

[0008] (4) In the design support system of (3) above, when the regulation-related information is determinable information, the processing unit determines whether the design value satisfies the regulations based on the regulation-related information, and outputs the determination result as the message, and the determinable information is information indicating that it is possible to determine whether the design value satisfies the regulations. According to this configuration, it is possible to notify the user whether the design value satisfies the regulations.

[0009] (5) In the design support system of (4) above, it further includes a restriction unit that restricts the operation of the design department that supports the drawing of architectural drawings. When the processing unit determines that the design value does not meet the regulations, it restricts the operation of the design department by issuing a command to the restriction unit.

[0010] According to this configuration, when the design value does not meet the regulations, the operation of the design department is restricted. As a result, it is possible to prevent the user from proceeding with the design while setting a design value that does not meet the regulations for a predetermined design item.

[0011] (6) In any one of the design support systems of (3) to (5) above, when the processing unit determines that the regulation-related information is difficult-to-determine information, as the message, it outputs confirmation-evoking information that prompts confirmation of whether the design value meets the regulations. The difficult-to-determine information is information indicating that it is impossible to determine whether the design value meets the regulations. According to this configuration, it is possible to arouse the user so as not to neglect confirmation regarding whether the design value meets the regulations for a predetermined design item.

[0012] (7) The design support program for solving the above problems is a design support program for supporting the design of a building. It causes a computer to execute a storage step of storing data in which an administrative area and regulation-related information related to regulations determined by the administrative agency of the administrative area regarding a predetermined design item of the building are associated, a first input step of receiving an input regarding the building site of the target building to be designed, a derivation step of identifying the administrative area including the building site of the target building and deriving the regulation-related information of the identified administrative area from the data, and an output step of outputting the regulation-related information. According to this configuration, since the regulation-related information is shown when the building site is input, the labor of grasping the regulations determined by each administrative area regarding the predetermined design item of the building can be reduced.

Effect of the Invention

[0013] The above-described design support system and design support program can reduce the effort of grasping the regulations determined by each administrative region regarding the predetermined design matters of a building.

Modes for Carrying Out the Invention

[0015] With reference to FIGS. 1 to 7, the design support system will be described. The design support system 1 is a system that supports the design of a building. The regulations related to the design of a building will be described.

[0016] The design of a building is restricted by regulations. The regulations are determined by an administrative agency or a parliament. Here, the regulations include laws, ordinances, rules, and circulars. The regulations define predetermined design matters (hereinafter, predetermined design matters) related to a building.

[0017] The predetermined design matters are matters related to structural design. Examples of the predetermined design matters include the vertical snow accumulation amount, the reference wind speed for calculating wind pressure, and the seismic regional coefficient for calculating seismic force. The vertical snow accumulation amount is a value for calculating the snow load. The vertical snow accumulation amount, the reference wind speed, and the seismic regional coefficient are used in the structural design of a building.

[0018] The content of the specified design matters varies by each administrative region. Since the snowfall amount varies greatly by region, the vertical snow accumulation amount is determined for each administrative region. Even within the same administrative region, the vertical snow accumulation amount may vary depending on the location. The way of regulating the vertical snow accumulation amount also differs for each administrative region.

[0019] For example, in the first administrative region, throughout the entire first administrative region, the vertical snow accumulation amount is set to a common fixed value. In the second administrative region, the vertical snow accumulation amount is determined for each subdivided area obtained by subdividing the second administrative region. In the third administrative region, in a specific area of the third administrative region, the vertical snow accumulation amount is set to a value calculated from a predetermined calculation formula including the altitude. In areas other than the specific area of the third administrative region, the vertical snow accumulation amount is set to a common fixed value. In the fourth administrative region, the vertical snow accumulation amount is determined on the map. Furthermore, in some administrative regions, there are also relaxation regulations for reducing the vertical snow accumulation amount. An example of the relaxation regulation is a regulation that reduces the vertical snow accumulation amount on the condition of snow removal.

[0020] Thus, the specified design matters differ for each administrative region, and the ways of regulation are also diverse. The regulations can be confirmed from the websites of the administrative agencies of each administrative region. However, the ways of explaining the vertical snow accumulation amount on the websites are also diverse. Due to such reasons, building designers require a lot of time to grasp the content.

[0021] The design support system 1 supports the design of buildings regarding the specified design matters as described above. The design support system 1 includes a database 11, a first input unit 12, a derivation unit 13, and an output unit 14. The design support system 1 further includes a second input unit 15, a processing unit 16, and a restriction unit 17. The design support system 1 further includes a storage unit 18. The storage unit 18 stores the information input via the first input unit 12 and the second input unit 15.

[0022] In one example, the database 11, the derivation unit 13, and the output unit 14 are provided in a server 21. The server 21 is configured with a computer and a storage device. The server 21 may be connected to a network N. Examples of the network N are the Internet, a local net, and a dedicated line network.

[0023] The first input unit 12, the second input unit 15, the processing unit 16, and the limiting unit 17 are provided in the terminal 22. The memory unit 18 may be provided in the terminal 22. The memory unit 18 may be provided independent of the terminal 22. The terminal 22 is, for example, a personal computer. The terminal 22 may have a design unit 19 and a display unit 20. The design unit 19 assists in drawing architectural drawings. The design unit 19 has a CAD (computer-aided design) program. The design unit 19 performs structural design calculations based on user input.

[0024] The display unit 20 displays a first input screen 25 of the first input unit 12, a second input screen 26 of the second input unit 15, and various messages 50. The display unit 20 is configured by a liquid crystal monitor, an organic EL monitor, or a CRT (cathode-ray tube) monitor.

[0025] The terminal 22 has some of the functions of the design support system 1. When the design unit 19 is provided in the terminal 22, the terminal 22 is also used for designing a building. The terminal 22 may be directly connected to the server 21. The terminal 22 may be connected to the server 21 via the network N.

[0026] The database 11 stores data. The data is data in which administrative districts are associated with law-related information. The law-related information is information related to laws and regulations established by administrative agencies of administrative districts regarding the specified design items of buildings. Specifically, the law-related information includes information regarding how laws and regulations are stipulated regarding the specified design items of buildings.

[0027] The data will be explained with reference to FIG. An example of the data format is a table. The data includes administrative regions and regulatory-related information. The data may include the names of the administrative regions. In the data, the administrative regions are associated with the regulatory-related information related to the regulations determined by the administrative organs of the administrative regions.

[0028] In the example described in FIG. 2, the predetermined design item is the vertical snow accumulation amount. The regulatory-related information is information related to the regulations determined by the administrative organs of the administrative regions regarding the vertical snow accumulation amount. The regulatory-related information includes at least one of the first information, the second information, the third information, the fourth information, and the fifth information.

[0029] The first information is information indicating whether the vertical snow accumulation amount is common throughout the administrative region. "Common throughout" indicates that the vertical snow accumulation amount is common throughout the administrative region. "Regional area" indicates that the vertical snow accumulation amount is defined by region within the administrative region.

[0030] The second information indicates how the vertical snow accumulation amount is defined. "Fixed value" indicates that a fixed value is set as the vertical snow accumulation amount in the administrative region or a specific location in the administrative region. "Calculation" indicates that the vertical snow accumulation amount is derived by a calculation formula.

[0031] The third information indicates the specific content determined by the administrative organ regarding the vertical snow accumulation amount. For example, "There is an area exceeding 80 cm" indicates that there is an area where the vertical snow accumulation amount must be a value greater than 80 cm.

[0032] The fourth information indicates the legal value of the vertical snow accumulation amount when the first information is "common throughout" and the second information is "fixed value". The fourth information is the information referred to by the processing unit 16 when the processing unit 16 creates the message 50.

[0033] The fifth information is information indicating whether a relaxation regulation is set regarding the vertical snow accumulation amount. The fifth information is the information referred to by the processing unit 16 when the processing unit 16 creates the message 50.

[0034] Referring to FIG. 3, the first input unit 12 will be described. The first input unit 12 is activated by a user operation. The first input unit 12 outputs a first input screen 25 to the display unit 20 upon activation. The first input unit 12 accepts input regarding property information about the building to be designed. Hereinafter, the building to be designed will be referred to as the "target building". Various types of information are associated with the property information. For example, the design drawing of the target building and the information input via the second input unit 15 are associated with the property information.

[0035] FIG. 3 shows the first input screen 25 of the first input unit 12. The first input screen 25 is shown on the display unit 20 of the terminal 22. The user can input property information about the target building via the first input unit 12.

[0036] The first input unit 12 sends the input information to the storage unit 18. Specifically, the first input unit 12 accepts input regarding the name of the target building. The name of the target building may be any name that can identify the target building. The name may be the name of the owner of the target building. The name may be the address of the construction site of the target building. The name may be the trade name of the target building.

[0037] The first input unit 12 accepts input regarding the construction site of the target building. The first input unit 12 may accept the construction site as a place name. The first input unit 12 may accept the construction site as latitude and longitude.

[0038] The first input unit 12 associates the name of the target building and the construction site and stores them in the storage unit 18. The first input screen 25 of the first input unit 12 includes a first input box 31 and a second input box 32. The first input box 31 is a box in which the "name of the target building" is input. The second input box 32 is a box in which the "construction site" is input.

[0039] The derivation unit 13 operates when a construction site is input to the first input unit 12. Alternatively, the derivation unit 13 operates along with the start of the operation of the second input unit 15. The derivation unit 13 identifies the administrative area in which the construction site of the target building is included. In one example, the derivation unit 13 identifies the administrative area in which the construction site is included based on administrative division data associating place names and administrative areas across the country. The administrative division data may be text data or map data. The derivation unit 13 derives the regulation-related information of the identified administrative area from the data. The derivation unit 13 associates the identified administrative area with the target building and stores it in the storage unit 18. The derivation unit 13 outputs the regulation-related information of the identified administrative area to the output unit 14.

[0040] The output unit 14 outputs regulation-related information. Specifically, the output unit 14 outputs to the second input unit 15 when the second input unit 15 is activated. The regulation-related information is used by the second input unit 15 as information shown on the second input screen 26 formed by the second input unit 15. The output unit 14 may output the administrative area in which the construction site of the target building is included together with the regulation-related information of the administrative area based on a user's request command.

[0041] Referring to FIG. 4, the second input unit 15 will be described. The second input unit 15 is activated by a user's operation. The user activates the second input unit 15 when setting design values for predetermined design items. The second input unit 15 forms a second input screen 26 upon activation and outputs the second input screen 26 to the display unit 20. The second input unit 15 forms a second input screen 26 including information regarding predetermined design items for the target building.

[0042] The second input unit 15 accepts input of design values for predetermined design items. In the present embodiment, the second input unit 15 accepts input of design values regarding the vertical snow accumulation amount. Specifically, the second input unit 15 accepts design values for the vertical snow accumulation amount, the use of relaxation regulations, and the elevation of the construction site. The second input unit 15 has a link that can access information related to regulations.

[0043] The second input screen 26 of the second input unit 15 includes a regional display box 40, a first display box 41, a second display box 42, a third display box 43, a third input box 44, a fourth input box 45, a first option button 46, a second option button 47, a first link button 48, and a second link button 49.

[0044] The regional display box 40 is a box indicating the administrative region. The administrative region indicates the building site of the target building. The administrative region shown in the regional display box 40 is the same as the administrative region input to the first input unit 12.

[0045] The first display box 41 is a box for displaying first information. The first information shown in the second display box 42 is the first information derived from the data by the derivation unit 13 based on the administrative region input to the first input unit 12.

[0046] The second display box 42 is a box for displaying second information. The second information shown in the second display box 42 is the second information derived from the data by the derivation unit 13 based on the administrative region input to the first input unit 12.

[0047] The third display box 43 is a box for displaying third information. The third information shown in the second display box 42 is the third information derived from the data by the derivation unit 13 based on the administrative region input to the first input unit 12.

[0048] The third input box 44 is a box for inputting the "design value" for the specified design items of the target building. The fourth input box 45 is a box for inputting the "elevation" of the building site of the target building.

[0049] The first option button 46 is a button selected when using the relaxation regulations in setting the set value for the vertical snow accumulation amount. The second option button 47 is a button selected when not using the relaxation regulations in setting the set value for the vertical snow accumulation amount.

[0050] The first link button 48 is a link button to a predetermined homepage. The predetermined homepage is a homepage managed by the administrative agency of the administrative region shown in the area display box 40 and is a page that explains the regulations regarding the predetermined design matters. The second link button 49 is a link button to map information representing the altitude of the whole country.

[0051] The user can obtain various information from the second input unit 15 regarding the regulations determined by the administrative agency of the administrative region where the construction site of the target building is located. The user can determine the design values by referring to the first information to the third information from the second input unit 15. The user can obtain accurate information regarding the regulations from the first link button 48. When the altitude is required when setting the design values, the user can check the altitude of the construction site from the second link button 49.

[0052] The second input unit 15 sends the input information to the storage unit 18. The design values input via the second input unit 15 are used by the design unit 19 and the processing unit 16. Specifically, the design values are used by the design unit 19 for structural design calculations. The design values are used by the processing unit 16 when creating the message 50.

[0053] Referring to FIGS. 5 to 7, the processing unit 16 will be described. The processing unit 16 outputs a message 50 related to the design values based on the input design values and the regulation-related information.

[0054] When a design value is input to the second input unit 15, the processing unit 16 outputs a message 50 related to the design value. The processing unit 16 displays the message 50 so as to overlap the second input screen 26 of the second input unit 15. The message 50 is displayed so as to cover the second input screen 26. When the user starts the CAD program of the design unit 19, the processing unit 16 may output a message 50 related to the design value. The message 50 includes at least one piece of information regarding the suitability of the design value and the precautions regarding the regulations related to the design value.

[0055] Describe the first operation of the processing unit 16. When the regulation-related information is determinable information, the processing unit 16 determines whether the design value meets the regulations based on the regulation-related information, and outputs the determination result as message 50. Determinable information is information indicating that it is possible to determine whether the design value meets the regulations.

[0056] Specifically, the determinable information is information that the first information is "common throughout the region" and the second information is "fixed value". In this case, since a common fixed value is set throughout the administrative region, it is possible to determine whether the "design value" meets the regulations of the administrative region based only on the "administrative region" and the "fixed value".

[0057] When the first information is "common throughout the region" and the second information is "fixed value", the processing unit 16 determines whether the design value is greater than or equal to the value of the fourth information. The value of the fourth information is a value specified by law.

[0058] When the processing unit 16 determines that the design value is greater than or equal to the value of the fourth information, it outputs message 50: "The design snow load meets the legal snow load." The output of message 50 may be omitted.

[0059] As shown in Figure 5, when the processing unit 16 determines that the design value is less than the value of the fourth information, it outputs message 50: "The design snow load does not meet the legal snow load. Please confirm the legal snow load and register the design snow load."

[0060] Describe the second operation of the processing unit 16. When the regulation-related information is difficult-to-determine information, the processing unit 16 outputs confirmation-calling information as message 50. Confirmation-calling information is information that prompts confirmation of whether the design value meets the regulations. Difficult-to-determine information is information indicating that it is impossible to determine whether the design value meets the regulations.

[0061] Specifically, the determination-difficult information is information other than the determinable information. For example, examples of the determination-difficult information include the information that the first information is "regional area", the information that the second information is "calculation", and the information that the fifth information is "with relaxation regulations". When the first information is "regional area", it is impossible to determine whether the "design value" meets the regulations of the administrative area only based on the "administrative area" and the "design value". When the second information is "calculation", it is impossible to determine whether the "design value" meets the regulations of the administrative area only based on the "administrative area" and the "design value". When the fifth information is "with relaxation regulations", it is impossible to determine whether the "design value" meets the regulations of the administrative area only based on the "administrative area" and the "design value". From such circumstances, when the regulation-related information is determination-difficult information, the processing unit 16 does not determine whether the design value meets the regulations, and outputs confirmation-calling information as message 50.

[0062] In one example, as shown in FIG. 6, when the first information is "common throughout the region", the second information is "fixed value", and the fifth information is "with relaxation regulations", and the set value does not satisfy the value of the fourth information, the processing unit 16 outputs message 50 including confirmation-calling information "The design snow accumulation does not meet the legal snow accumulation before the use of relaxation regulations such as snow removal. If you use relaxation regulations such as snow removal, please register the use."

[0063] In another example, as shown in FIG. 7, when the first information is "regional area", the processing unit 16 outputs message 50 including confirmation-calling information "In this administrative area, different legal snow accumulations are specified depending on the area, so please be careful."

[0064] When the processing unit 16 determines that the design value does not meet the regulations, it restricts the operation of the design unit 19 by issuing a command to the restriction unit 17. The restriction unit 17 is configured to restrict the operation of the design unit 19. The restriction unit 17 is configured by a program. Examples of the restriction include prohibiting the operation of the structural design calculation of the design unit 19 and invalidating the operation of starting the design unit 19.

[0065] For example, when the first information is "common throughout the area" and the second information is "fixed value", if the set value does not satisfy the value of the fourth information, the processing unit 16 issues a command to the restriction unit 17 to restrict the operation of the design unit 19. At this time, since the operation of the design unit 19 is restricted, the user cannot perform structural design by the design unit 19.

[0066] The operation of the design support system 1 will be described. When the user inputs a design value for a predetermined design item of the target building, the second input unit 15 is activated. The derivation unit 13 operates together with the second input unit 15. The derivation unit 13 acquires the building site of the target building from the first input unit 12 or the storage unit 18, specifies the administrative area from the building site, and derives the regulation-related information corresponding to the administrative area from the data. The output unit 14 outputs the regulation-related information to the second input unit 15. The second input unit 15 forms the second input screen 26 using the regulation-related information derived by the derivation unit 13. The regulation-related information is shown on the second input screen 26.

[0067] When the user inputs a design value via the second input screen 26, the processing unit 16 operates. The processing unit 16 executes predetermined processing based on the design value and the regulation-related information. When the regulation-related information is determinable information, the processing unit 16 determines the appropriateness of the design value and outputs a message 50 including the determination result regarding the design value. When the regulation-related information is difficult-to-determine information, the processing unit 16 outputs a message 50 prompting confirmation of whether the design value satisfies the regulations.

[0068] The operation of this embodiment will be described. In the design support system 1, the database 11 stores data in which administrative regions and law-related information are associated. According to the database 11, by specifying an administrative region, the law-related information of the administrative region can be derived from the data stored in the database 11. The derivation unit 13 specifies the administrative region in which the construction site of the target building is included, and derives the law-related information of the specified administrative region from the data. The law-related information is information related to the laws determined by the administrative organs of the administrative region regarding the predetermined design matters of the building. The output unit 14 outputs the law-related information. Therefore, the user can obtain the law-related information regarding the predetermined design matters and grasp the laws regarding the predetermined design matters by inputting the construction site of the building.

[0069] The effects of this embodiment will be described. (1) The design support system 1 includes a database 11, a first input unit 12 that receives an input regarding a construction site, a derivation unit 13, and an output unit 14 that outputs law-related information. The database 11 stores data in which administrative regions and law-related information are associated. The derivation unit 13 specifies the administrative region in which the construction site of the target building is included, and derives the law-related information of the specified administrative region from the data. According to this configuration, since the law-related information is shown when the construction site is input, the labor of grasping the laws determined by each administrative region regarding the predetermined design matters of the building can be reduced.

[0070] (2) The law-related information includes information regarding the way of regulation of the laws regarding the predetermined design matters of the building. According to this configuration, the content of the laws regarding the predetermined design matters of the building can be easily grasped.

[0071] (3) The design support system 1 further includes a second input unit 15 that receives an input of a design value for a predetermined design item, and a processing unit 16. The processing unit 16 outputs a message 50 related to the design value based on the regulation-related information and the design value. The message 50 includes at least one piece of information on the suitability of the design value and precautions regarding regulations. According to this configuration, since the user can receive the message 50 for the design value, appropriate measures can be taken for the predetermined design item of the target building.

[0072] (4) When the regulation-related information is determinable information, the processing unit 16 determines whether the design value satisfies the regulations based on the regulation-related information, and outputs the determination result as the message 50. According to this configuration, it is possible to notify the user whether the design value satisfies the regulations.

[0073] (5) The design support system 1 includes a restriction unit 17. The restriction unit 17 restricts the operation of a design unit 19 that supports the drawing of architectural drawings. When the processing unit 16 determines that the design value does not satisfy the regulations, the processing unit 16 restricts the operation of the design unit 19 by issuing a command to the restriction unit 17.

[0074] According to this configuration, when the design value does not satisfy the regulations, the operation of the design unit 19 is restricted. As a result, it is possible to prevent the user from proceeding with the design while setting a design value that does not satisfy the regulations for a predetermined design item.

[0075] (6) When the regulation-related information is difficult-to-determine information, the processing unit 16 outputs, as the message 50, confirmation prompting information that prompts confirmation of whether the design value satisfies the regulations. According to this configuration, it is possible to prompt the user so as not to neglect the confirmation regarding whether the design value satisfies the regulations related to the predetermined design item.

[0076] <Modification Example> The above-described embodiment is an exemplification of the forms that the design support system 1 can take, and is not intended to limit the form. The design support system 1 can take a form different from the form exemplified in the above-described embodiment. An example thereof is a form in which a part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. An example of a modification of the embodiment is shown below.

[0077] · This technology can be configured as a design support program. The design support program includes the following steps to be executed by a computer. The design support program has a storage step, a first input step, a derivation step, and an output step. The computer includes a server 21 and a terminal 22. The terminal 22 may be connected to the server 21 via a network N or may be directly connected to the server 21.

[0078] The storage step is a step of operating the computer to store data. Specifically, the storage step includes a step of maintaining a storage state in which the computer stores data. The data is data in which an administrative area and regulation-related information are associated. The regulation-related information is the same as the content shown in the embodiment.

[0079] The first input step is a step of operating the computer to receive an input regarding the construction site of a target building that is the design object. In one example, the first input step operates the computer to output a first input screen 25 to the display unit 20 and receive an input via the first input screen 25.

[0080] The derivation step is a step of operating the computer to identify the administrative area in which the construction site of the target building is included, and further operating the computer to derive the regulation-related information of the identified administrative area from the data.

[0081] The output step is a step of operating a computer to output regulation-related information. In one example, the output step causes the computer to output the regulation-related information to the second input unit 15. In another example, the output step causes the computer to output, based on a user's request command, the regulation-related information of the administrative area including the building site of the target building to the display unit 20.

[0082] According to the design support program, if a building site is input, the regulation-related information is shown to the computer. Therefore, the labor of grasping the regulations determined by each administrative area for the predetermined design items of the building can be reduced.

[0083] · The processing unit 16 may have a checking function of checking the regulations determined by the administrative organs of the administrative area. The processing unit 16 checks whether there is any change in the regulations by the checking function. In one example, the processing unit 16 stores a copy of the homepage of the administrative organ for each administrative area. The processing unit 16 accesses the homepage of the administrative organ at a predetermined timing, compares the homepage of the administrative organ at the time of access with the homepage of the administrative organ copied at the previous access, and detects the difference in the homepage. When there is a difference in the homepage, the processing unit 16 outputs a caution message indicating that the regulations may have been amended for the area where the difference in the homepage has occurred. The predetermined timing may be a predetermined cycle or a timing based on the user's designation.
