Since it is usually a small pattern on weekends and public holidays, the buildings of related units are used in the same normal offices as well as hospitals, schools and factories that do not operate late at night, which may have similar energy consumption patterns. Etc. are searched. In addition, if the use of the target building is a family apartment, not only family apartments but also detached houses that are considered to have similar energy consumption patterns are searched for as the range of related units.
- the search item of the type of equipment it is possible to search for a unit in charge of equipment that is considered to exhibit the same type of behavior in terms of energy balance as the equipment in charge.
- the equipment of the target building is a combination of a turbo chiller and three cold / hot water pumps
- search items such as the total floor area and the air-conditioning area
- search items such as the total floor area and the air-conditioning area
- each area in the range increased or decreased by ⁇ 50% is in charge It is stipulated to search for units.
- the range is determined from the viewpoint of searching for items that show similar patterns in terms of energy.
- the numerical range to be increased or decreased may be appropriately changed and used as necessary.
- the related units searched in such a range are similar to the target unit in terms of energy balance, and the skill and knowledge of the engineers managing the related units are excellent for the target unit. May have applied operational conditions that are superior to current operational conditions for energy conservation. Therefore, it is possible to introduce better operational conditions by searching for such related units.
- the storage unit 200 includes other information that is necessary for the operation of the unit, such as a basic program that controls the entire flow including the initial processing flow and the steady processing flow, but is not illustrated in FIG. Is also stored.
- FIG. 3 is a flowchart showing an initial process flow of the target unit in such a case.
- an initial processing flow will be described with reference to FIGS.
- step S100 When one new unit is installed in the target building, the initial flow of FIG. 3 starts, and first, an initial processing step regarding the target unit is executed (step S100).
- the relationship between the unit initial processing unit 110 that executes this step and other means inside the unit is shown in FIG.
- the arrows in FIG. 4 indicate the main flow direction of information, and so on.
- FIG. 5 is a flowchart showing the details of step S100 in more detail. In the flow of FIG. 5, first, all other units of the system are searched, and the building name and address that can identify the building where the target unit is installed are read from the unit specific information table 210 of each unit.
- the unit installed in the same building as the target unit is specified, and the identification information is set as the internal unit in the internal unit specification table 220.
- the unit initial processing unit 110 and the unit specific information table 210 function as an identification unit that distinguishes each unit from other units.
- the internal unit specifying table 220 can be used as an identification means.
- the calculation item information for calculating the energy balance of the range in charge of the internal unit is read from the unit specific information table of each internal unit. Further, the calculation item information of the range in charge of the target unit is read from the unit specific information table 210. The data is read and stored in the latest / condition identification table 270 (step S120). Subsequently, based on the calculation item information read from the other internal units, the energy balance calculation formulas and operation conditions of the assigned range are read from each internal unit and stored in the latest formula / condition specifying table 270 (step S130). . In addition, the process of S120 step and S130 step is preparation for performing the energy balance simulation of the whole object building in an object unit.
- the calculation item for calculating the energy balance of the target unit in charge, the energy balance calculation formula, and the operating conditions are transmitted to the other internal units.
- the other internal units that have received the information store the information in their latest state / condition identification table (step S140). This is to allow optimization in other internal units including newly added units.
- each internal unit reflects the changed information in the relationship table transmitted from the target unit in its own relationship table. This is because the target unit is in charge of new equipment and sensors that other existing internal units do not have information on, or other existing internal units ignore the elements that are ignored as having little effect. If the target unit is used to improve control accuracy, or if the target unit has been restarted after removing some of the existing internal unit equipment, This is a process for performing the optimization process in the internal unit more appropriately.
- step S200 the operation of the equipment in charge of the target unit is optimized within the range of the energy balance calculation formula and the operating conditions stored in advance in the target unit.
- the optimization process is performed on the entire target building in the case where the facility in charge affects other facilities in terms of energy.
- FIG. 6 shows the relationship between the internal / overall optimization processing unit 120 that executes this step and other processing units.
- step S200 a set of energy balance calculation formulas and operation conditions as candidates for the equipment in charge of the target unit is selected from the relational expression / condition table 250 (step S210).
- the selection may be performed with some priority, but in this example, selection is made in order from the one stored in the head of the table.
- step S215 step it is determined whether or not the facility in charge of the target unit has an energetically influence on other facilities of the target building, that is, whether or not there is a relationship. If there is no relationship, the flow branches left and proceeds to step S255, and if there is a relationship, the flow branches downward and proceeds to step S220. In this way, if there is a relationship, it is not possible to separate only the part in charge of the target unit from the others for optimization, and the energy balance of the entire target building cannot be separated. This is because optimization simulation or the like needs to be performed, but conversely, if there is no relationship, only the portion in charge of the target unit needs to be optimized. Note that the optimization when there is no relationship is performed in the subsequent step S300.
- step S220 when there is a relationship, the operation condition of the portion in charge of the internal unit taken into the internal unit information table 240 is read and changed based on the relationship table.
- a fan that takes in outside air has been newly installed when the room temperature has been adjusted to a predetermined appropriate temperature in the summer by using only an air conditioner.
- the fan operating condition is set to operate the fan when the room temperature is higher than the appropriate temperature and the outside air is 3 ° C. lower than the room temperature. In this case, energy is required to operate the fan, but if the outside air temperature is much lower than the room temperature, the room temperature is lowered by the driving of the fan, so the operation of the fan affects the air conditioning load of the air conditioner.
- the driving energy of the air conditioner is larger than the driving energy of the fan. Therefore, the operating condition of the air conditioner is changed from the continuous operation until then to the time when the fan operates. It is preferable to change the operating conditions to stop. Thus, further energy saving can be achieved by appropriately changing the operation conditions based on the relationship.
- the existing unit controls the lighting equipment so that the number of lighting lamps is adjusted according to the number of people in the room, the angle of the blinds attached to the windows is adjusted.
- the case that equipment was newly installed is raised.
- the angle of the blinds so that a lot of sunlight can enter the room during the daytime in winter when the weather is fine, it is possible to prevent any trouble from occurring even if the illumination lamp at the window is turned off. Therefore, when the angle of the blind is adjusted as such, it is preferable from the viewpoint of energy saving to change the operating condition of the lighting equipment so that the lighting lamp at the window is turned off.
- taking sunlight into the room also affects the air conditioning load, so the operating conditions of the air conditioner are also changed.
- lighting lamps must be lit by closing the blinds and blocking sunlight, but the air conditioning load will be reduced, so the lighting and air conditioning facilities will be operated to save more energy. The condition will be changed.
- step S225 data read out from the internal unit information table 240 and appropriately changed for the entire target building including the portion in charge of the target unit, the energy balance calculation formula and operating conditions of the target unit selected in step S210 And the data of the measurement information table 290, an energy simulation for one day is performed to calculate the assumed energy consumption (step S225).
- the flow skips step S225 and immediately proceeds to step S230.
- step S230 it is determined whether or not the assumed daily energy consumption of the entire target building is lower than the current daily energy consumption (step S230). If the assumed energy consumption is equal to or greater than the current energy consumption, the flow branches to the left and proceeds to step S255. If the assumed energy consumption is smaller than the current energy consumption, the flow branches downward and proceeds to step S235. In this case, the combination of the energy balance calculation formula selected as a candidate in step S210 and the operation conditions may be more effective in energy saving than the current one, so that further demonstration operation is performed.
- the step S230 is executed for the first time, the current daily energy consumption data and the assumed daily energy consumption data do not exist, so the flow skips the step S230 and goes to the step S235. Move.
- step S235 the energy balance calculation formula and operation conditions changed in step S220 are transmitted to other internal units (step S235). This is because the test operation can be performed on the entire internal unit by changing each unit operation condition to one corresponding to the candidate operation condition.
- step S240 the test operation is performed for one day, the measurement information from the sensors is stored in the measurement information table, and the actual energy balance is calculated. Subsequently, in step S245, the actual energy balance obtained in step S240 is compared with the energy balance under the conventional conditions used so far, and the energy balance calculated in step S240 is compared with the conventional energy balance. Further, it is determined whether or not energy is saved (step S245).
- the flow unconditionally branches to the left and proceeds to the step S255.
- the energy balance calculation formula and operation conditions selected as candidates are regarded as conventional, and the following processing is performed.
- step S245 when the energy balance calculated in step S240 is more energy-saving than the conventional energy balance, the combination of candidates selected in step S210 is more effective in terms of energy saving in actual measurement. Therefore, the test operation is continued as an actual operation as it is, the result is stored in the optimum formula / condition specifying table 270 and the control history information table 260, and the flow branches to the left and proceeds to step S255.
- step S245 if the energy balance calculated in step S240 is not the same or less than the conventional energy balance, the candidate selected in step S210 is not particularly effective in terms of energy saving in actual measurement. Since it was found that there was no such operation, an operation to cancel the conditions used in the test operation of the candidate is performed, the setting of the target unit is returned before step S210, and all the internal units are set in step S235. An instruction to cancel the contents transmitted to change and return to the previous state is transmitted (step S250), and the process proceeds to step S255.
- step S255 the relational expression / condition table 250 is searched to determine whether or not all combinations of candidate energy balance calculation formulas and operation conditions have been tested for the equipment in charge of the target unit (step S210). If there are candidates that have not been tested, branch to the right and go to step S210. If a new candidate is selected and all candidates are tested, all combinations have been tested. Branches down and ends the process. This completes the entire flow of FIG. 7, that is, step S200 of FIG.
- step S200 when the facility in charge affects the other facilities in terms of the operation of the facility in charge of the target unit, optimization for energy saving is performed on the entire target building. Process. This is because when each facility does not affect other facilities in terms of energy, the scope of optimization processing must be the entire target building, and only the scope of responsibility of the target unit. The amount of processing and time required for the optimization process differ greatly depending on which case is possible, so that optimization for energy saving can be performed with less processing. is there.
- step S300 in FIG. 3. Unlike the step S200, this step processes a case where the assigned equipment can be regarded as having no energy relationship with the assigned equipment of other internal units. Therefore, an optimization process for only the equipment in charge of the target unit may be performed.
- Step S300 is shown in detail in the flowchart of FIG. FIG. 8 shows the relationship between the internal / local optimization processing unit 130 that executes step S300 and other means.
- a set of candidate energy calculation formulas and combinations of operation conditions is selected from the relational expression / condition table 250 for the equipment in charge of the target unit (step S310). For this selection, one set may be selected from those determined to be unrelated in step S215 in FIG. 7, but in this example, the same selection process as in step S215 is simply performed again. Yes. Subsequently, with reference to the relationship table 230, it is determined whether or not the facility in charge of the target unit has an energy influence on the other facilities of the target building, that is, whether there is a relationship (step S320). If there is an energy relationship with other equipment, the flow branches to the left and proceeds to step S390 to determine whether there is a next candidate.
- step S330 the flow branches down to step S330, and the selected energy balance calculation formula, operation conditions, data in the measurement information table 290, and the data regarding the assigned range of the target unit Is used to perform an energy simulation for one day, and the assumed energy consumption is calculated (step S330).
- the flow skips step S330 and proceeds to step S340 because there is no necessary data as in the process in step S225 of FIG.
- step S340 it is determined whether or not the assumed daily energy consumption in the target range of the target unit is lower than the current daily energy consumption (step S340). If the assumed energy consumption is equal to or greater than the current energy consumption, the flow branches to the left and proceeds to step S390. If the assumed energy consumption is smaller than the current energy consumption, the flow branches downward and proceeds to step S350 to actually perform the test operation. In addition, when installing a unit and moving to S340 step first, a flow skips S340 step and moves to the test operation of S350 step.
- step S350 a test operation is performed for one day, measurement information from sensors is stored in a measurement information table, and an actual energy balance is calculated. Subsequently, in step S360, the actual energy balance obtained in step S350 is compared with the energy balance under the conventional conditions used so far, and the energy balance calculated in step S350 is compared with the conventional energy balance. Further, it is determined whether or not energy is saved. If the assumed energy consumption is greater than or equal to the current energy consumption, it is clear that it is not possible to save more energy, so the flow branches down and proceeds to step S380. In step S380, the control performed using the candidate combination for the test operation is returned to the state before the test operation, and the process proceeds to step S390.
- step S350 in step S360 is more energy-saving than the conventional energy balance
- the candidate combinations selected in step S310 are more effective in terms of energy saving in actual measurement. Since it was proved, the test operation is continued as an actual operation as it is, the results are stored in the state-of-the-art / condition table 270 and the control history table 260, and the flow branches right from the S360 step to the S370 step. . Note that when the unit is first installed and the process proceeds to step S360, there is no data in the measurement information table 290 measured by the assigned sensors, so the flow unconditionally branches to the right and proceeds to step S370.
- the energy balance calculation formula and operation conditions selected as candidates are regarded as conventional, and the following processing is performed.
- step S370 the energy balance calculation formula and operation conditions selected in step S310 are transmitted to another internal unit for simulation in the other internal unit, and the flow proceeds to step S390.
- step S390 it is determined whether or not there is a candidate combination that has not been selected in step S310 in the combination of the energy balance calculation formula and the operation condition of the portion in charge stored in advance in the relational expression / condition table 250. If so, the process returns to step S310 to select a new candidate combination and continue the process.
- step S400 a related unit is searched.
- the related unit here refers to a unit that may use a new operation condition or the like that can improve the level of energy saving of the target unit (and the target building) from the current level.
- this related unit search not only internal units installed in the target building but also external units installed in buildings other than the target building are set as search targets. By doing in this way, it is possible to widely search for better operating conditions for energy saving without being limited to the technology for energy saving used in the target building and the knowledge of the person in charge. become.
- FIG. 11 shows an example of a detailed flowchart of the related unit search in step S400.
- search items such as the positional relationship in the building, such as the number of floors and directions, and the daily rate of the outer wall in the assigned range can be selected and used in advance according to the characteristics of the target building and the assigned facility.
- search for example, a search with a unique name of a centrifugal chiller is performed to search for a device including the device with the same device name, or a COP (equipment operating efficiency) value is included within a certain range. Search for items that are within a certain range, and search for items that have a high degree of approximation of the external environment of the unit, or the degree of approximation of the operation pattern You can search for things like those that contain high values.
- the search range table 300 determines in advance which units are hit in the related unit search process for these search items.
- FIG. 10 shows the relationship between the related unit search processing unit 140 that performs related unit search and other means.
- step S410 the usage of the target building of the target unit and the unit installed in the building of the usage in the similar range with reference to the search range table are searched, and the identification information And the result indicating that it is related to the usage is stored in the related unit specifying table 280 (step S410).
- the assigned units of the target unit and the units having the same assigned facilities are narrowed down with reference to the search range table, and the result is stored in the related unit specifying table 280. (Step S420).
- step S420 From the group of units searched in step S420, further narrow down the units having the total floor area of the assigned range of the target unit and the assigned floor area of the assigned range that can be said to be the similar range by referring to the search range table, and the result Is stored in the related unit identification table 280 (step S430).
- step S430 Subsequently, out of the group of units searched in step S430, further narrow down the units having the air-conditioning area of the assigned range of the target unit and the air-conditioning area of the assigned range that can be said to be the similar range with reference to the search range table, The result is stored in the related unit identification table 280 (step S440). Finally, the priority is assigned from the unit having the highest number of hits in each step from the first to a predetermined number, and is left in the related unit specification table 280 as a related unit (step S450). Units with a small number of hits are likely to be unsuitable for the operating conditions of the target unit, and it is desirable to continue the test operation for at least one day. If there are too many candidates, it takes days to optimize.
- the load of optimization processing is reduced by reducing the number of examination candidates.
- the number of examination candidates is limited to 30. Since the units are narrowed down in each step in this way, it becomes possible to select units with operating conditions more suitable for the equipment in charge of the target unit. This completes the flow search process of FIG. 11, that is, step S400 of FIG. 3, and then proceeds to step S500 of FIG.
- FIG. 12 shows the relationship between the internal / external part optimization processing unit 150 that executes step S500 and other means.
- the detailed flow of step S500 is shown in the flowchart of FIG.
- a unit with a high priority is selected from the related unit identification table 280, and the operating conditions and the like of the equipment in charge corresponding thereto are set as assumed conditions (step S510).
- step S510 the operating conditions and the like of the equipment in charge corresponding thereto are set as assumed conditions
- step S520 combine this assumption with the energy balance calculation formulas and operation conditions of the target unit and other internal units read from the optimal / condition identification table 270, and perform a simulation that covers the entire internal unit. Is calculated (step S520).
- the relationship table 230 is not referred to here, in the related unit, the structure of the target unit and the target building is generally different, and the relationship data of the related unit does not correspond to the target unit. There is a possibility. Therefore, it is desirable to simulate not only the area in charge but also the entire internal unit.
- the assumed energy balance is compared with the current energy balance to determine whether or not the assumed energy balance is more energy saving (step S530). If the assumed energy balance is not more energy saving, the flow branches to the left and proceeds to step S580. Also, if the assumed energy balance is more energy saving, the flow branches down to step S540, where the assumed conditions are transmitted to other internal units to prepare for the test operation. Subsequently, the process proceeds to step S550, where a test operation is performed for one day to determine whether the energy can actually be saved from the current condition according to the assumed conditions, and the test energy balance is measured. Next, it is determined whether or not the test energy balance is more energy-saving than the current energy balance (step S560).
- step S580 it is determined whether there is a related unit that has not yet been selected in the related unit identification table 280. If it remains, the process returns to step S510 to repeat the flow, and if not, the process ends. To do. This completes the flow of FIG. 13, that is, the S500 step of FIG. 3, and the initial processing of FIG. 3 when a new unit is added to the system or the setting of an existing unit is changed and restarted. The flow ends.
- FIG. 14 shows a flowchart example corresponding to the flowchart of FIG. 3 when the assigned units of the target unit are three of a, b, and c.
- FIG. 14 shows a flowchart example corresponding to the flowchart of FIG. 3 when the assigned units of the target unit are three of a, b, and c.
- three steps of Sa200 step, Sb200 step, and Sc200 step are provided in FIG.
- FIG. 14 there are provided Sa300 steps, etc., in charge of processing related to three of the assigned facilities a, b, c corresponding to each of the steps S300 and S500 in FIG. 3.
- the necessary steps may be increased in accordance with the number of facilities.
- each unit controls the equipment in charge and controls the energy balance of the area in charge on a daily basis based on the operation conditions determined to be optimal and the measurement information from the sensors.
- the overall flow is shown in FIG.
- the daily operation process is performed (step S600).
- FIG. 16 shows the relationship between the operation processing unit 170 that executes daily operation processing and other means.
- the unit routinely controls the operation of the assigned equipment using the measurement information of the assigned sensors and the operation conditions.
- Equipment control is performed using operation conditions determined according to the characteristics and status of each equipment and target values included in the operating conditions.
- the target value is, for example, a formula set by initial assumption or a correlation formula calculated from monitoring data (autocorrelation, correlation with others, regression formula, multiple regression, etc.) according to external conditions such as outside temperature, humidity, and internal personnel. It may be determined in advance using an equation or the like.
- the comfort index is because the heat and cold felt by humans depend on temperature, humidity, radiation temperature, air flow velocity, human activity, clothing wear (CLO value), thermal resistance, etc. This is calculated using the comfort equation developed by Fanger, taking into account the above factors, and using CO 2 concentration and CO concentration as necessary.
- PMV 0, statistically 95% of people feel comfortable without being hot or cold, the numbers fluctuate within the range of plus or minus 3, and when PMV becomes positive, 95% of people feel hot and negative It means to feel cold.
- the minimum illuminance required for the work that is assumed to be performed in each room based on the size of each room, the size and position of the window, the daily illuminance, and the information on the number of people in the room.
- a control target value is set based on a predetermined calculation formula for each room with respect to the number of illuminations obtained and their positions. This is because, in a place where sufficient illuminance can be obtained for daily work by sunshine, it is energy saving to turn off the lights.
- the equipment is a window opening / closing device, the temperature, humidity, rainfall, air volume, wind direction, etc. outside the building, and information such as whether the temperature, humidity, working hours, etc.
- each room is in advance. Based on the determined calculation formula, it is determined whether or not ventilation is performed by opening each window so as to reduce the operating energy of the air conditioner while maintaining the comfort index, and set as a control target value for each window. For example, when the outside air temperature is lower than the room temperature, it is more energy efficient to open the window and ventilate the air conditioner than to cool it.
- the type and number of devices that have been on standby for a predetermined time or more in advance when the power is on are previously determined.
- the control target values are determined so that they are turned off, and thereafter the control target value is used to control the power supply to be turned off so that the number of waiting devices is reduced.
- Control is performed using the target value set in this way and the operating conditions including the target value.
- the interval during which the control is performed once is relatively long and short in the case of air conditioning control, for example. It is desirable to set a unit time of about 5 to 10 minutes.
- step S700 determines whether there is a newly added unit in the system or a unit that has been restarted due to a change in facilities.
- the internal unit search process from another unit is determined based on whether or not the internal unit search process has been performed after the previous daily operation process of the target unit has been completed. In a system that includes multiple buildings, there are routine restarts due to the addition of new units and changes in equipment. This is because it can be taken in quickly. If there is no added unit, the flow branches to the left and returns to step S600, and the daily operation process is performed again. If there is a unit that has been added, the flow branches down to determine whether the added unit is a related unit according to the same search items and search range as the flow in FIG. Determine (step S710).
- step S800 An additional partial optimization process is executed (step S800).
- the relationship with other means of the additional partial optimization processing unit 160 that executes this step S800 is shown in FIG.
- a detailed flowchart of step S800 is shown in FIG.
- the additional partial optimization process of FIG. 18 is performed except that the added unit specified in steps S700 to S710 is selected and used instead of the related unit searched in the initial process selected in the flow of FIG. Since the processing is performed in the same manner as the flow of FIG. 13, detailed description thereof is omitted. Therefore, even in this flow, better operating conditions are always searched for due to the addition of new units or the restart of existing units, so as time passes, each unit will have multiple buildings where the units are installed. By learning each other about the optimum conditions in the system, it becomes possible to improve the level of energy saving of the entire system. This ends the step S800, and the flow returns to the daily operation process again. Thereafter, the unit repeatedly executes the flow of FIG. 15 until some break operation is performed.
- FIG. 15 is an example of the daily operation processing flow when one unit is in charge of one piece of equipment.
- FIG. 18 shows an example of a flow in the case where one unit is in charge of three facilities a, b, and c as in FIG. Comparing FIG. 18 and FIG. 15, the daily operation processing at step S600 in FIG. 15 corresponds to the three responsible facilities a, b, and c in FIG. 18, and the three operations of Sa600 step, Sb600 step, and Sc600 step are performed. The difference is that one step is provided.
- the operation processing of the three responsible facilities is executed in order, then the optimization processing related to the additional unit is performed, and the daily operation processing of the responsible facilities is performed again. In this way, even when there are a plurality of responsible facilities, it becomes possible to perform processing without any particular problem.

- the table configuration of the storage unit and the step contents of the flow of each control unit are specifically described. However, even if various modifications and order changes are made to these, substantially the same functions are provided. May be able to achieve.
- the operation conditions that are candidates for examination are selected in order from the top of the table, or the priorities are selected in advance. The selection may be made randomly, or may be made using an artificial intelligence technique such as a genetic algorithm.
- the unit can select an appropriate condition from among control methods, set values, variables, etc. in various environments, such as temperature and humidity conditions of outside air and ease of use of the building. Minimize. First, a simulation is performed according to a specific setting and a control method, or actual control is started. As a result, when the expected minimum is not reached, the setting is changed a little and simulation is performed again to determine a difference from the assumed minimum. This is repeated while changing a plurality of control methods, set values, and variables, and a result that can be finally determined to be the minimum is recorded as an optimization result, and then the result is reused.
- the unit can set conditions for control by measuring and recording various conditions such as outside air temperature, humidity, and wind direction. It is possible to analyze what control conditions are appropriate in accordance with a combination of measured values of a plurality of sensors.
- the logic of the optimization process may be single or may be used in combination. For example, all optimization processes may be the same logic, or at least one may be different logic.
- the source of new operating conditions is explained when it is supplied from a unit newly installed in the system, or when an existing unit is restarted due to addition or change of equipment, etc.
- the operation condition suitable at a certain point in the past can be called again by autocorrelation processing of measurement information of one unit.
- room conditions such as temperature, humidity, solar radiation, rainfall, wind speed, and other outside air conditions, and the number of internal personnel, lighting load, outlet load, production load, etc. Since there may be a time zone that is very similar to that, it is desirable to change the optimization condition in time series based on autocorrelation for this similar time zone. For example, the operating conditions that were optimal in one summer due to seasonal fluctuations, etc., are likely to be optimal again in the summer of the following year, even if they are changed without being suitable for the next winter. is there.
- the energy simulation is described in the case where the initial processing and the steady processing are performed using measurement information for one day.
- the energy simulation can be performed in less than one day when the assigned range is in the activity state. .
- the system is constructed as an aggregate of units, but the system can be configured as a server client system.
- An example of the configuration is shown in FIG. In FIG. 20, the server 3 and the client 2 (only one client is shown for the sake of simplicity) are communicably connected via the communication network 12.
- the server 3 is provided with the control means 100 and the storage means 200 among the functions of the unit 1 shown in FIG. Thereby, a server performs the optimization process regarding storage of various data, and an object building.
