First, a process-based energy management system according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5. FIG.

FIG. 1 is a schematic view illustrating a configuration of a process-based energy management system according to an embodiment of the present invention.

As shown in FIG. 1, the process-based energy management system 100 according to an embodiment of the present invention enables an operator or user of a facility to be an energy management entity to efficiently manage the energy use of the facility .

In particular, the process-based energy management system 100 according to the present invention guides the execution procedure of the energy management business so that the energy management business can be progressed sequentially, and thereafter, And provides the result to the system user.

Hereinafter, the configuration of the process-based energy management system 100 according to the present invention will be described in more detail.

The process-based energy management system 100 according to the present invention includes a process map management module 110, a project management module 120, an energy management module 130, and a database 140 as shown in FIG. .

First, the process map management module 110 provides the user with a process map (MAP) generated for each predetermined energy management task, so that the user can refer to the process map as a template to create a project And so on.

Here, the process map refers to a set of standard processes required to perform each energy management task according to a predetermined type of energy management task. At this time, the standard process refers to a plurality of time series processes required to perform the corresponding energy management task.

In addition, each process consists of standard subprocesses required to perform each process. At this time, the sub-processes refer to a plurality of sub-processes in a time series required to perform the process.

Therefore, the process map according to the present invention can be defined as data configured in a tree form, as shown in FIG. 2A, in which a process map is a top-level entity and a sub-process is a bottom-level entity.

The process map management module 110 provides such a process map to a user so that a user using the energy management system 100 can select a process map that matches the type of energy management task he or she intends to perform.

This process map is stored in the database 140, and the process map management module 110 can read the processor map from the database 140 and provide it to the user.

In one embodiment, the process map may be generated in the first five phases and stored in the database 140. Specifically, the process map can be generated by dividing into a standard for providing an energy management system, a customer discovery step, a preliminary diagnosis step, a detailed diagnosis step, an energy management system execution step, and an energy management system operation step.

First, the process map of the standard and customer discovery stages is a step of inducing the construction of the energy management system through the promotion of the energy management system. The process map of the standard and customer discovery stage is the process map of the energy management system The process of collecting information of the customers who are building the energy management system, the process of selecting the customers, and the energy management system. And may include a process of promoting.

The process map of the preliminary diagnosis phase, the process map of the detailed diagnosis phase, and the process map of the operation phase of the energy management system are the processes for planning the energy management task for diagnosis, the process for diagnosing energy efficiency, A process for calculating the solution, a process for calculating the economics for each of the calculated solutions, and a process for generating the operation scenario using the calculated solution.

The process map of the implementation phase of the energy management system includes processes for planning the energy management tasks, processes for installing the hardware devices of the energy management system, processes for establishing the network infrastructure, data monitoring and analysis for system construction And a process for customizing the system.

Particularly, in the case of the energy efficiency diagnosis process included in each process map, in order to perform the energy efficiency diagnosis process, data acquisition for diagnosis, setting of the measurement status and equipment status, generation of physical model, And may include at least one sub-process.

Although the process map management module 110 has been described as providing the process map stored in the database 140 to the user in the above embodiment, the process map management module 110 may update the process map , Or edit a previously created process map.

Specifically, as shown in FIG. 3A, the process map management module 110 provides a UI screen to the user to add or edit a process map, thereby allowing a user to add a new process map, Allows you to edit the map.

First, in association with the addition of a new process map, when addition of a process map is requested from the user, the process map management module 110 provides a UI screen to which a new process map can be added as shown in FIG. 3A. At this time, the user can add a new process map by referring to another previously created process map as a template. For example, when a process map previously created in the template menu shown in FIG. 3A is selected, as shown in FIG. 3B, the process map management module 110 includes a pre-created process map, And provides a user with a process and a sub-process, thereby making it possible to add a new process map using the created process map as a template.

Next, with respect to editing of the process map, if editing of the process map is requested from the user, the process map management module 110 provides the UI screen shown in Fig. 3C to the user, If any one is selected, as shown in FIG. 3D, a UI screen for editing the processes included in the selected process map is provided. If any one of the processes shown in FIG. 3D is selected, as shown in FIG. 3E, the user can edit a corresponding process map by providing a UI screen for editing the sub-processes included in the selected process .

In the above embodiment, the project map management module 110 generates a new project map using the generated project map. However, in the modified embodiment, the project map management module 110 may include the project management module 110, A new project map may be generated using the project generated by the project management unit 120 as a template.

For example, the project map management module 110 maps the projects, which are generated by the project management module 120, to projects having the use frequency higher than the reference value as templates, A new process map can be generated by mapping a sub-task to a sub-process. At this time, the process map management module 110 may map all the tasks and all sub-tasks included in each project to the processes and sub-processes, but only the tasks selected by the user are mapped to the processes, Only sub-tasks selected by the user can be mapped to sub-processes.

The project map management module 110 stores the newly added process map and the edited process map in the database 140.

Next, when the process map corresponding to the target energy management task to be performed by the user is selected from among the process maps provided by the process map management module 110, the project management module 120 processes the processes included in the selected process map And loads subprocesses. In addition, the project management module 120 maps the processes selected by the user among the loaded processes and sub-processes to a task for actual execution of the target energy management task, and processes the sub- And generates a project of the target energy management task by mapping to a subtask for actual execution of the task.

That is, the project management module 120 has the same structure as that of the process map having the structure as shown in FIG. 2A, and as shown in FIG. 2B, the project management module 120 sets the project as the highest entity and the subtask as the lowest entity A tree-shaped project is created for each target energy management task.

For example, when a request for creating a project for performing a target energy management task is inputted from a user, the project management module 120 provides a UI screen for adding a new project as shown in FIG. 4A. At this time, as described above, the project management module 120 refers to the process map provided by the process map management module 110 as a template, and provides an icon for selecting a template so as to create a new project. 4B, the process map provided by the process map management module 110 and the processes and sub-processes included in each process map are loaded and output, The process included in the process map selected by the user is mapped to the task, and the sub-process included in the process map selected by the user is mapped to the sub-task.

In this case, the project management module 120 may map all loaded processes to a task, and map all loaded sub-processes to a subtask to create a project. However, in another embodiment, 4c, a user can delete a sub-task included in each task or add a new sub-task by providing a UI screen for editing a sub-task included in each task.

In one embodiment, the project management module 120 receives a task execution order from a user in a process of mapping a process to a task and mapping a sub-process to a subtask, Or an execution order of each sub task may be assigned to each sub task by receiving the execution order of each sub task. In particular, the project management module 120 may enable each sub-task to be executed at a predetermined launcher by allowing each sub-task to set an execution time at which each sub-task should be executed.

In the above-described embodiment, the project management module 120 describes that a new project is created using the project map provided by the project map management module 110 as a template. However, in the modified embodiment, the project management module 120 may generate a new project using the other project created by the project management module 120 as a template.

That is, when a project corresponding to the target energy management task to be performed by the user is selected among other previously created projects, the project management module 120 loads the tasks and subtasks included in the selected project, And a task of the target energy management task using tasks and sub-tasks selected by the user among the sub-tasks.

As described above, the present invention can reuse other pre-generated projects, thereby guiding a user who performs the same or similar energy management tasks to generate a project more easily.

Next, the energy management module 130 diagnoses the target facility to be an energy management target according to the energy management task, calculates the expected effect of the energy efficiency and the energy efficiency improvement of the target facility, and the solution execution , And monitors the target facility to determine whether the calculated expected effect is maintained.

Particularly, the energy management module 130 according to the present invention executes a task and a subtask included in each project for each project generated by the project management module 120, so that the target energy management task corresponding to each project We calculate energy efficiency, energy efficiency improvement solution, and expectation effect of solution implementation of target facility targeted for energy management.

In one embodiment, when the target energy management task is an energy efficiency analysis for the target facility, the energy management module 130 executes tasks and subtasks included in the project generated for the energy efficiency analysis, Analyze energy efficiency and provide analysis results to users.

To this end, the energy management module 130 includes a guide module 510, a data acquisition module 520, a modeling module 530, and an analysis module 540, as shown in FIG.

First, the guide module 510 confirms the execution order of the tasks and the execution order of the subtasks set for each task and each subtask included in each project, and determines whether the execution order and the execution timing of each task and sub task have arrived . If it is confirmed that the execution order and the execution timing of each task and subtask have come, the user is provided with access information of a menu for execution of each task and subtask, so that the user can perform the task and the sub task .

For example, if the sub-task to be performed to perform the target energy management task is the generation of the physical model, the guide module 510 checks whether or not the execution timing of the sub-task for generating the physical model has arrived, (E.g., link information for activating the modeling module 530) of the menu for creation of the physical model by using the modeling module 530.

As described above, according to the present invention, through the guide module 510 included in the energy management module 130, when a task or a subtask of each project is to be executed, access information that can execute the corresponding task or subtask automatically is provided to the user So that the user can guide the task or subtask to be performed more easily.

Next, when the execution timing of the subtask for acquiring data among the sub-tasks comes, the data acquisition module 520 acquires the measurement data from the sensors that are activated according to the user's selection and matched with the target facilities to be subjected to energy management Collects the data, and processes the collected measurement data into a cubic format composed of three axes of equipment type, energy type, and time.

Specifically, the data acquisition module 520 collects the measurement data from the sensors installed in the field by matching with the respective target facilities, stores the collected measurement data in a form usable in the energy management system, 540).

2, the data acquisition module 520 includes a data collection unit 552, a data correction unit 554, and a data processing unit 556, and includes a first database 557, A database 558, and a third database 559. Although the first database 557, the second database 558 and the third database 559 are shown as being included in the data acquisition module 230 in FIG. 2, this is only one example, and only the first database 257 ), The second database 558, and the third database 559 may be physically separated from the data acquisition module 520.

First, the data collecting unit 552 collects measurement data from various sensors disposed on the site, and matches the collected measurement data with each of the facilities modeled by the modeling module 260 to generate a first database 257, . That is, the data collecting unit 552 matches the raw data acquired from various sensors with the information of the matching facilities with the corresponding sensors, and stores the matching data in the first database 257.

The data refinement unit 554 refines the measurement data stored in the first database 257 according to a predetermined refinement rule to select valid data and stores the selected data in the second database 558 do. In the present invention, the measurement data, which is raw data, is refined through the data refinement unit 554 because the measurement data collected from the sensors include all the abnormally measured values, Therefore, only valid data among the measurement data collected from the sensors is selected.

Next, the data processing unit 556 processes the data refined by the data refining unit 554 and stored in the second database 558 into a predetermined format, and stores the processed data in the third database 559.

In one embodiment, the data processor 556 generates data stored in the second database 558 in a cube format composed of three axes of facility type, energy type, and time as shown in FIG. 6 .

Here, the facility type refers to the target facilities modeled by the modeling module 260, and the energy type means an energy source type such as electricity, gas, water, and the like. The time refers to a time key for summing up the measurement data. For example, the data processing unit 556 stores the measurement data in the Raw Data, 5-minute unit sum data, 30-minute unit sum data, , And the measurement data is accumulated by a predetermined time unit such as the daily unit sum data, the monthly sum data, the branch unit sum data, the half-unit sum data, and the annual sum data.

For example, the data processing section 556 stores the measurement data as a time key, a facility ID (or facility type ID), an energy type ID, measurement data of the facility at the time, and units of measurement data And other attributes that they contain.

In the present invention, the reason that the data processing unit 556 processes the data stored in the second database 558 into a cube format as shown in Fig. 3 is that various viewpoints (energy type perspective, time perspective, Type perspective), as well as a large amount of data can be derived in a short time since the measurement data are pre-summed in units of a predetermined time.

In this way, by managing the measurement data in the form of cubes, it is possible to diagnose and analyze the energy type change according to the change of the equipment when diagnosing the energy utilization efficiency of the target facilities using the analysis module 270, Analysis, and diagnosis and analysis of energy type changes with time.

Next, when the execution timing of the subtask for generating the physical module among the sub-tasks arrives, the modeling module 260 is activated in accordance with the selection of the user to connect the target facility, the connection relationship between the target facilities, Points are modeled.

Specifically, the modeling module 260 provides a tool for graphically representing the connection relationship between each facility and each facility to register the facility points of the target facility and the target facilities in the energy management task, To model the installation points of the target facility and each target facility.

That is, the modeling module 260 registers the information of all equipments and equipments created by using the corresponding tool, defines the input-output energy used by each equipments, registers the relation between the equipments before and after the equipments, Model facility points for each facility.

More specifically, the modeling module 260 supports the P & ID-based design scheme symbol, allowing the user to freely place equipment used in general manufacturing industry fields such as pumps, valves, tanks, dust collectors, cranes, etc. .

In particular, the modeling module 260 according to the present invention can express the order of association of equipment according to the process flow, so that the modeling result can be used for future energy flow analysis. In addition, the instrument information included in the facility can be set together so that it can be easily known where the measurement data is collected, and the type and structure of the data transmitted by the measurement sensors can be defined. Upon completion of modeling by the modeling module 260, the information is immediately exported to the data acquisition module 250 so that the data can be immediately received.

Next, when the execution timing of the subtask for generating the diagnostic model among the sub-tasks arrives, the analysis module 270 activates according to the selection of the user and becomes the target facility to be diagnosed and the target of diagnosis And generates a diagnostic model including the target period. In addition, the analysis module 270 extracts a value corresponding to the diagnostic model from the data of the cube format processed by the data acquisition module 250, and generates the diagnosis result by diagnosing the energy efficiency of the target facility.

Specifically, when the modeling of the target facilities is completed by the modeling module 260, the analysis module 270 diagnoses the performance or efficiency of the target facility based on the cube-shaped data generated by the data acquisition module 250 .

In one embodiment, the analysis module 270 sets the characteristics related to the flow rate and pressure, and the channel resistance in the target facilities (e.g., compressors, blowers, pumps, etc.) using the fluid, A first diagnostic module (not shown) for analyzing the energy efficiency of the target facilities using the fluid, a second diagnostic module (not shown) for diagnosing the energy efficiency of the lighting equipment and the heating and cooling equipments, a standby module A third diagnosis module (not shown) for diagnosing whether the standby mode of the facilities is normal if there are facilities in operation, a unit cost management by energy type, a cost calculation based on usage amount, and a waste amount calculation And a fourth diagnostic module (not shown) for quantifying the expected effects, and an analysis of power usage patterns according to the amount of power used, A may include a fifth diagnostic module (not shown) to manage the idle and replacement schedule.

Although the first to fifth diagnostic modules are included in the analysis module 270 in the form of modules independent of each other, the analysis module 270 in the modified embodiment is only one example. All the functions performed by the first to fifth diagnostic modules may be integrally performed.

The analysis module 270 according to the present invention first generates a diagnostic model for diagnosing performance or efficiency of the target facilities and extracts necessary data according to the diagnostic model from the data of the cube form generated by the data acquisition module 250 The diagnosis of the target facilities is performed.

Here, the generation of a diagnostic model means a process of determining which target equipment (target equipment) is to be diagnosed for a certain period of time (target period) and setting a determination criterion necessary for diagnosis. At this time, the determination criteria necessary for the diagnosis include the upper and lower limit values of the measurement data, the efficiency characteristic curve of the target facility, and the efficiency determination reference value, and these information are used for activation of the subtask analysis module 270 for generating a diagnostic model The user inputs it using the analysis module 270.

Hereinafter, a method of diagnosing the performance or efficiency of the target facilities will be described with reference to the analysis module 270, for example. In the following example, a method of diagnosing the performance and efficiency of a fluid device (for example, a pump) in which a fluid is used will be described as an example.

First, the analysis module 270 specifies a fluid device as a target facility to be diagnosed according to information input from a user, and sets a target period for diagnosing the specified fluid device. Then, the analysis module 270 extracts the measurement data of the flow rate during the target period and the target period from the cube-shaped data related to the flow rate used in the specified fluid device. Also, the analysis module 270 extracts measurement data on the discharge pressure of the fluid device during the object period and the object period from the cubic data related to the discharge pressure of the specified fluid device. Also, the analysis module 270 extracts measurement data on the system pressure of the fluid device during the object period and the object period from the cube-shaped data related to the system pressure of the fluid device.

Here, the discharge pressure of the fluid device refers to the pressure on the output side or discharge side of the pump which is the fluid device, and the system pressure of the fluid device means the pressure on the end of the demand side where the final delivery is collected using the pump.

In addition, the analysis module 270 extracts measurement data on the consumed power value of the fluid device during the target period and the target period from the cube-shaped data related to the power for driving the specified fluid device. This is for comparing the flow rate and pressure of the pump, which is a fluid device, with the power and the power value required for the operation of the actual pump.

Then, the analysis module 270 calculates the discharge pressure of the fluid-fluid device based on a predetermined mapping rule, taking the flow rate as the X axis, the discharge pressure of the fluid device as the Y1 axis, the system pressure of the fluid device as the Y2 axis X, Y1) coordinates and maps the system pressure of the flow-fluid device to the (X, Y2) coordinates.

In one embodiment, the analysis module 270 may be configured to perform the mapping between the mapping between the discharge pressure of the flow-fluid device and the system pressure of the flow-fluid device, wherein the measurement cycle of the flow rate sensor and the pressure- A time key for synchronizing the measurement cycle is generated and the number of data generated by the flow measuring sensor and the ratio of the data generated by the pressure measuring sensor are confirmed using the time key. Here, the time key means to determine whether to map the flow data by subdividing the flow data, or to group the pressure data and to map the pressure data.

If the timers of the respective sensors are different from each other, the analysis module 270 checks the timers of the sensors disposed in the field in advance to correct the time difference between the sensors, And the mapping is performed after reflecting on the data.

In one embodiment, when the data measured by each sensor is not collected every measurement period or abnormal measurement data is collected due to a malfunction of each of the sensors, a power trip, or the like, the analysis module 270 ) Can determine N (for example, N = 5) average values of data immediately before a drop occurs or a drop immediately before a drop occurs to recover the missing measurement data.

Then, the analysis module 270 obtains the theoretical efficiency value of the pump from the ideal characteristic curve of the pump and the ideal efficiency curve of the pump, calculates the relationship between X-Y1 and X-Y2 by the section integration method, And the measurement efficiency value is calculated. Thereafter, a section in which the efficiency improvement is possible is derived by comparing the theoretical efficiency value and the measurement efficiency value in the section, and the size of the derived section is converted into the power unit. Then, the analysis module 270 quantifies the expected efficiency improvement effect of the pump by multiplying the value converted by the power unit by the power rate, and provides the result to the user.

According to this example, the diagnosis result by the analysis module 270 can be provided to the user in the form as shown in FIG. 7, the first region 710 represents the final power supplied to the systematic pressure of the pump and the second region 720 represents the final power supplied to the discharge pressure of the pump. Accordingly, the analysis module 270 provides the user with a result of decreasing the size of the second area 720 to the size of the first area 710 and quantifying the expected effect in the improvement.

Also, the analysis module 270 derives a solution for improving the energy efficiency of the target facility using the diagnosis result, and predicts whether the solution is applied to the field through simulation. For example, in the above-described example, if the expected efficiency improvement effect of the pump is diagnosed, the analysis module 270 can obtain the expected effect such as the inverter installation, the pulley improvement, and the impeller wear improvement for the variable flow rate operation of the pump And can provide users with solutions that can actually be improved to implement. In addition, after applying the solution of the analysis module 270 to the field, the actual improvement effect can be monitored and managed to determine whether the improvement effect is maintained or recovered.
