Description

Diagnostic and Manging Method of New Renewable Energy Apparatus Using Mobile Device and the System
Thereof
Technical Field
The present invention relates to a method of diagnosing and managing new renewable energy equipment units using mobile devices, and the system thereof; and specifically, relates to a diagnostic and management method, and the system thereof, for new renewable energy equipment units using mobile devices that can not only provide real-time feedback on on-site diagnostic results at a certain minimum level or above regardless of the skill level of the worker, but can also have information on the specific causes and severity levels of failures and other information transmitted immediately to a diagnostic server when failure modes occur on-site so that the analysis and response methods for the respective failures can be transmitted to workers, thus making it possible to respond promptly and correctly to failures and to also transmit this information in real-time to other workers.
Background Art
With growth in the installed base of power generation equipment using new types of environmentally friendly renewable energy, such as wind power electric generators and solar power electric generators, in order to deal with the issues of depleting energy resources and environmental pollution, there is also increasing demand for continuous maintenance, repair and inspection of these new renewable energy equipment units to ensure their stability and reliability.
Ordinarily, the management of new renewable energy equipment units is carried out by workers performing on-site diagnostic and maintenance work, with these workers filling out inspection items and other detailed information manually before and after carrying out the work, while taking and saving photographs of the work process with mobile phones and other devices before transferring this information to reports prepared after returning to the office.
However, though work plans are provided to workers for this diagnostic work, the amount of information input about each inspection item varies depending on the skill level of the worker, so that it is not easy to maintain a diagnostic quality level above a certain level.
Also, if inspection items are omitted or errors made when filling out the diagnostic results so that it is not possible to complete diagnostic work that meets the inspection standards, the worker must revisit the site, and this reduces the efficiency of the diagnostic work.
At the same time, when assessing failures while performing diagnostic work on specific equipment, determinations of the specific causes and severity levels of those failures, as well as the methods of dealing with them, must depend completely on the performance of the on-site worker, and this makes it impossible to ensure reliability in the maintenance and repair process. It is also not easy to convey the diagnostic information about failures to other workers in real-time, further hindering efforts to increase efficiency in the diagnostic work.

Problems to be Solved
Therefore, an objective of the present invention is to provide a diagnostic and management method for new renewable energy using mobile devices, and its system thereof, that can maximize diagnostic efficiency by providing real-time feedback on information input when a worker inputs diagnostic results about equipment on-site so as to achieve diagnostic performance at a certain minimum level or above regardless of the skill level of the worker and without the need to revisit the site in order to re-diagnose items input in error.
Also, another objective of the present invention is to provide a diagnostic and management method for new renewable energy using mobile devices, and its system thereof, wherein diagnostic results input by workers are transmitted to and saved on the diagnostic server in real-time so that when abnormal conditions occur on-site, the failure information, including information on specific causes and severity levels, is transmitted immediately to the diagnostic server so that the analysis of and methods of responding to the respective failures can be transmitted to the worker, making it possible to respond quickly and precisely to failures.
Additionally, another objective of the present invention is to provide a diagnostic and management method for new renewable energy equipment units using mobile devices, and its system thereof, wherein the types and degrees of failures are classified and graded when abnormal conditions occur for specific inspection items so that it is easy for workers to report about abnormal conditions and for supervisors to perform qualitative and quantitative analysis of abnormal conditions, thus maximizing diagnostic work efficiency.
Further, another objective of the present invention is to provide a diagnostic and management method for new renewable energy equipment units using mobile devices, and its system thereof, wherein information about problems is quickly propagated in real-time to workers who are diagnosing the same new renewable energy equipment units on-site so that other workers can focus on and diagnose the respective inspection items, thus maximizing diagnostic work efficiency.
Means of Solving the Problems
Based on one embodiment of the present invention, the above objectives are achieved through a diagnostic and management method for new renewable energy equipment units using mobile devices through a process that comprises the following steps: a step of using a mobile device to connect to a diagnostic and management server; a step of determining whether the diagnostic and management server is to grant the connection to the mobile device; a step of transmitting task information that includes equipment information and inspection item information corresponding to the identifying information of the new renewable energy equipment units that the mobile device which the diagnostic and management server has granted a connection is to inspect; a step of transmitting the inspection results information for each inspection item for the new renewable energy equipment unit which has been input and saved on the mobile device to the diagnostic and management server; a step of evaluating the inspection results information received by the diagnostic and management server against the inspection standards set up for each inspection item; and a step wherein, if it is determined that the inspection results need to be re-input, the diagnostic and management server sends a request to the mobile device to have the inspection results information for the inspection items re-input and transmitted, and saves the inspection results information if it is determined that the initially input and transmitted inspection results information or the re-input and transmitted inspection results information received from the mobile device has been input correctly.
Here, the step wherein the diagnostic and management server evaluates the inspection results information may include determinations of whether the required inspection item information has been input, whether photographs have been attached for inspection items requiring images, the resolution of the attached photographs or whether the area to be photographed is included, whether the severity level of the failure has been input and/or whether the results of performing maintenance and repairs have been input.
The step wherein the diagnostic and management server evaluates the inspection results information may comprise a step of evaluating whether each of the inspection items included in the inspection results received is within the normal condition range set for the respective inspection item; and a step of requesting and receiving from the mobile device the input and transmission of repair results information, including information on specific causes, information on severity levels, worker comment information and/or information on how to respond to the inspection items determined by the diagnostic and management server to be in an abnormal condition.
Here, the step of the diagnostic and management server requesting repair results information may comprise a step of the diagnostic and management server transmitting to the mobile device repair instructions information that includes pre-set information on specific causes, severity level information and/or ways of responding to the respective inspection items; and a step of transmitting from the mobile device to the diagnostic and management server repair results information that includes information on specific causes, severity level information, worker comment information and/or ways of responding which are input optionally or additionally depending on the repair instructions information.
Meanwhile, the diagnostic and management server process further comprises a step of extracting same-model identifying information for other new renewable energy equipment units having same-model identifying information as the new renewable energy equipment unit exhibiting the abnormal condition inspection item information; a step wherein the diagnostic and management server changes whether inspection items under the task information evaluated to be in an abnormal condition and corresponding to each unit of same-model identifying information are mandatory, changes their inspection priority and/or changes their inspection schedule; and a step of updating and saving the repair results information input and received from the mobile device in the repair instructions information.
Here, the diagnostic and management server process may further comprise a step of transmitting inspection item information, inspection results information and repair results information on abnormal conditions to the mobile devices of other workers inspecting new renewable energy equipment units having same-model identifying information.
Here, equipment information may include model information corresponding to identifying information, as well as the respective installing company information, information on the power generation estate to which the new renewable energy equipment unit belongs and/or manufacturer information, and inspection item information may include inspection item lists, inspection-related manuals, information on how to evaluate severity levels when inspecting, information on normal condition range values, information on inspection standards colour coding, information on inspection methods, whether inspections are mandatory, inspection priorities and/or inspection schedule information.
In addition, the process may further comprise a step wherein an inspection report is generated on the mobile device based on the inspection results information; and a step of transmitting the generated inspection report to the diagnostic and management server.
At the same time, based on another embodiment of the present invention, the above objectives are also achieved through a diagnostic and management system for new renewable energy equipment units using mobile devices that comprises a database on which task information is saved that includes equipment information and inspection item information corresponding to the identifying information of multiple new renewable energy equipment units installed in multiple locations; mobile devices belonging to workers diagnosing the respective new renewable energy equipment unit; and a diagnostic and evaluation server having a connection authentication module that determines whether to grant connections to the mobile devices, a send/receive module, a control module that extracts from the database task information corresponding to the identifying information of a new renewable energy equipment unit which is to be inspected by a mobile device granted a connection and saved in the database the inspection results information on the inspection items received from the mobile device, and a diagnostic and evaluation module that evaluates the inspection results information against the inspection standards set up for each of the inspection items and requests re-input from the mobile device if it is determined that the information needs to be re-input.
Here, inspection item information may include inspection item lists, inspection-related manuals, information on how to evaluate severity levels when inspecting, information on normal condition range values, information on inspection standards colour coding, information on inspection methods, whether inspections are mandatory, inspection priorities and/or inspection schedule information, and the mobile device may include an image generation module, a send/receive module, and an input/output module to search task information received from the diagnostic and management server and input inspection results information.
The diagnostic and evaluation module evaluates whether inspection results information received is within the normal condition range values set for each inspection item included in the inspection results received, and the control module can transmit and display the evaluation results of the diagnostic and evaluation module to and on the mobile device through the send/receive module.
The control module can extract from the database the repair instructions information that includes pre-set information on specific causes, severity level information and/or information on how to respond of and to the respective inspection items determined to be in an abnormal condition and transmits this information to the mobile device, and also receives from the mobile device repair results information that is optionally or additionally input based on the repair instructions information, including information on specific causes, severity level information, worker comment information and/or information on how to respond, and updates this information to the inspection results information and repair instructions information.
The control module can extract same-model identifying information from the database for other new renewable energy equipment units having same-model identifying information as the new renewable energy equipment unit exhibiting the abnormal condition inspection item information and change whether inspection items under the task information evaluated to be in an abnormal condition and corresponding to each unit of identifying information are mandatory, change their inspection priority and/or change their inspection schedule.
The control module can transmit through the send/receive module the inspected item information, inspection results information and repair results information of the abnormal condition to the mobile devices of other workers inspecting new renewable energy equipment units having same-model identification numbers.
Mobile devices can further comprise a report generation module that generates inspection reports based on completed inspection results information.
Effects of the Invention
Therefore, the diagnostic and management method for new renewable energy equipment units using mobile devices based on the present invention, and its system, can maximize diagnostic efficiency by providing real-time feedback on information input when a worker inputs diagnostic results about equipment on-site so as to achieve diagnostic performance at a certain minimum level or above regardless of the skill level of the worker and without the need to revisit the site in order to re-diagnose items input in error.
Furthermore, this method has the advantage of eliminating the need for workers to separately prepare reports after diagnostic work, thus maximizing worker convenience and making it possible for work supervisors to quickly gather reliable reports.
Also, according to the diagnostic and management method for new renewable energy equipment units using mobile devices under the present invention, and the system thereof, diagnostic results input by workers are transmitted to and saved on the diagnostic server in real-time so that when abnormal conditions occur on-site, the failure information, including information on specific causes and severity levels. is transmitted immediately to the diagnostic server so that the analysis and methods of responding to the respective failures can be transmitted to workers, making it possible to respond quickly and precisely to failures.
Furthermore, the diagnostic and management method for new renewable energy equipment using mobile devices under the present invention, and the system thereof, exhibits the advantage of being able to maximize diagnostic efficiency by having the types and degrees of failures classified and graded when abnormal conditions occur for specific inspection items so that it is easy for workers to report about abnormal conditions and for supervisors to perform qualitative and quantitative analysis of abnormal conditions.
Also, it is possible to maximize reliability of the diagnostic work by editing the task information that includes the inspection items for which failure modes have occurred to make inspection items mandatory, raise their priority or shorten their inspection schedule.
Also, by quickly propagating information about problems in real-time to workers performing diagnostic work on the same kinds of new renewable energy equipment units on-site, these other workers can perform diagnostic work by focusing on the respective inspection items, thus maximizing diagnostic efficiency.

Detailed description of the Invention
The following is a detailed description of the embodiments of the present invention, with reference to the attached drawings.
Referring to Figure 1, the diagnostic and management system (1) for new renewable energy equipment units using mobile devices based on one embodiment of the present invention comprises mobile devices (30) belonging to workers, a diagnostic and management server (10) and a database (20).
Before starting the description, it is hereby made clear that new renewable energy equipment units (100) in this specification refers specifically, for example, to power generation equipment that uses new renewable energy, such as wind power electric generators and solar power electric generators, but that the application of the present invention is not limited to the new renewable energy field, and can be applied without limit to various fields and types of electric equipment on which diagnostic work is performed.
The following is the description, starting with the individual components.
New renewable energy equipment unit (100) refers to a single power generation equipment unit installed in a specific location and operating independently so as to be assigned unique identifying information that distinguishes it from other power generation equipment. In other words, power companies may have multiple power generation estates, and each power generation estate may have multiple power generation equipment units, so that identifying information may include information about the power company and the power generation estate.
The database (20) is where task information is stored that includes equipment information and inspection item information corresponding to each type of identifying information for multiple new renewable energy equipment units (100) installed in multiple locations.
Here, the task information can be saved in both the database (20) and mobile devices (30), and in this case, if a mobile device (30) and the diagnostic and management server (10) are connected through wired or wireless networking, the information on each of the devices is synchronized.
The task information includes equipment information and inspection item information on new renewable energy equipment units (100).
The equipment information is information on specific new renewable energy equipment units (100), and may include the model names of the respective new renewable energy equipment units (100) and their GPS locations, installation dates, detailed configurations, the manufacturers and classifications of the gearboxes being used and the persons-in-charge.
The inspection item information includes inspection item lists, inspection-related manuals, information on how to evaluate severity levels when inspecting, information on normal-condition range values, information on inspection-standards colour coding, information on inspection methods, whether inspections are mandatory, inspection priorities and/or inspection schedule information.
The inspection item information may be provided in a tree structure of two levels or more.
This is related to the user interface (Ul) on the mobile devices (30) and provides the benefit of enabling workers to easily find many inspection points.
For example, the inspection item information corresponding to a certain new renewable energy equipment unit (100) can be provided in two tree structures, “Assembly” and “Components”. “Assembly” can be provided for any one configuration having two or more detailed inspection items (“Components”) on a specific power generation equipment unit, and, for example, if the new renewable energy equipment unit (100) is a wind power electric generator, can be provided with “Tower”, “Hub”, “Nascelle”, “Gear Box” and the like.
For “Assembly”, a configuration filter can be set up based on how the lower-level “Components” can be configured. The purpose of the configuration filter is to flexibly support changes in the inspection items for unknown new renewable energy equipment units (100) and so, for example, if the electric generator of a certain manufacturer can use various different gear boxes, then the gear and bearing structure of each gearbox can be different from each other. It is often the case that a specific configuration cannot be known before making an on-site visit to inspect the electric generator of another company which does not belong to the inspecting company and so using the configured filter makes it possible to check the configuration of the electric generator on-site in order to flexibly substitute and replace inspection items. If this kind of filter is not applied, the inspection information defaults to the lower-level “Component”. “Component” includes the names of inspection items. Under “Components”, multiple inspection items can be added in the same way, and the manuals related to the inspection can be linked to or information on how to evaluate severity levels when inspecting, reference values and reference colours can be displayed. The inspection items have classifications, and these generally include visual inspection, functional inspection, measurement inspection, endoscopic inspection and the like.
In this case and for each inspection item, it can be displayed whether a necessary inspection item is mandatory, and if inspection results information on mandatory inspection items have not been input, the diagnostic and management server (10) can notify the worker through the mobile device (30) accordingly so that the diagnostic work can be performed correctly.
On the other hand, under “Component”, it is possible to provide additional information—meaning, repair instructions information—in advance on possible causes (detailed information on causes) that correspond to the failure mode and information on ways of resolving these (information on how to respond). A failure mode means that the diagnostic and evaluation module (17) evaluates that the inspection results information input corresponds to an abnormal condition so that the specific cause information includes details on what type of failure it is and its classification (for example, issues with corrosion, scratches, illumination, lubrication, etc.)
Meanwhile, information on how to respond includes information on how the worker can deal with the failure, making it possible for the worker to take appropriate action immediately even if having no detailed knowledge of the respective new renewable energy equipment unit (100).
Here, task information can be provided that includes information on the type of power generation estate and the functions of the power generation equipment operating, if of the same new renewable energy equipment units (100), or various types of other task information configured as mutually different combinations of inspection items lists based on the purpose of the diagnostic and management work.
Information on inspection results performed by workers and generated inspection reports related to the task information can be additionally saved in the database (20).
Mobile devices (30) are devices belonging to workers performing diagnostic work on individual new renewable energy equipment units (100) that can be connected to the diagnostic and management server (10) through wired or wireless networking.
Various types of well-known devices may be used without restriction as mobile devices (30), including smartphones, tablet computers and notebook computers, and specifically, mobile devices may be provided as smartphones on which specialized applications have been installed to perform diagnostic work.
Mobile devices (30) comprise an image generation module (31), a send/receive module (33) and an input/output module (35).
The send/receive module (33) receives task information from the connected diagnostic and management server (10).
Here, in order for workers to perform diagnostic work on-site, task information may be received from the mobile devices (30) whenever they are connected to the diagnostic and management server (10), but as described above, the task information may be already saved on the mobile devices (30).
In the latter case, the worker can still check the task information and perform diagnostic and management work even if wired or wireless networking is unavailable in the location at which a new renewable energy equipment unit (100) is installed. Later, the task information and inspection results information on inspections performed is synchronized with the diagnostic and management server (10) when returning to an area where wired or wireless networking is available. Here, the standard time for the synchronization shall be based on the time on the diagnostic and management server (10). Meanwhile, when multiple mobile devices (30) access the database (20) through the diagnostic and management server (10), multiple connections are permitted for read-mode access, but when accessing in write mode, a sequence is assigned so that updates are performed in order.
The input/output module (35) searches for task information received from the diagnostic and management server (10) and inputs the inspection results information. Edits of task information through the input/output module (35) are synchronized with the diagnostic and management server (10) through the send/receive module (33) and are propagated after that to other mobile devices (30) or to the diagnostic and management server.
The image generation module (31) is provided to take photographs when photographs must be added to certain inspection items of the task information.
At the same time, mobile devices (30) may comprise a report generation module (37) that generates inspection reports based on completed inspection results information.
This is explained as follows, with reference to Figures 2 and 3.
Figures 2 and 3 show the screens displayed through the input/output module (35) on mobile devices (30).
On the far left, a special tab (Figure 2a) is provided to provide statistics generated after drafting the inspection report, which is to be described later. After that, the “Assembly” list is displayed on the tap strip and the “Component” list is located there as the content for each tab (“Assembly”) (Figure 2b). If photographs and evaluations already exist for each “Component”, these are shown together with the thumbnails list and highest severity levels (right-side number on Figure 2c), in addition to the photographs.
On the other hand, as previously described, mandatory inspection items for specific “Components” that must be performed are highlighted on the screen as in Figure 2d, and if the inspection results information has not been input, the inspection report cannot be generated.
Showing the mandatory inspection items that must be performed ensures that the worker only has to perform the minimum necessary diagnostic work, while also giving the worker discretion to look for mandatory inspection items and perform only those when there is a lack of time for other required diagnostic work.
The system is configured so that upon viewing sub-screens for each “Component” on mobile devices (30), detailed descriptions of how to inspect specific inspection items, additional photograph buttons and severity levels and comments for each “Component” (Figure 3a and 3b) are shown. Multiple photographs can continue to be added through the image generation module (31). This is done using the internal camera of the mobile device (30), but the camera can be controlled directly through the system API without using an external camera app in order to adjust the resolution, the flash modes and the size of the photographed part, and to crop and make colour adjustments.
The image generation module (31) separates and manages the area for photographs taken by the worker from other photograph data (photograph source management), and photographs that need to be uploaded to the diagnostic and management server (10) can be uploaded only when the mobile device (30) is currently on a wi-fi network. If an upload fails, it can be re-attempted for each photograph individually.
If, after taking a photograph, the diagnostic and evaluation module (17) determines there to be a failure mode (abnormal condition) or the worker determines him/herself that there is an abnormal condition, the system switches to failure mode and generates repair results information in which the severity levels in the photographs are evaluated and containing the specific causes and how to respond, as well as comments by the worker (Figure 3c & 3d). In this case, the repair instructions information provided to the diagnostic and management server (10) can be edited or additionally input by default.
The diagnostic and management server (10) determines whether to grant a connection to the mobile device (30), and instructs the diagnostic work to the mobile device (30), evaluates the diagnostic results performed and saves the inspection results information and inspection report in the database (20).
To do this, the diagnostic and management server (10) comprises a connection authentication module (11), a send/receive module (13), a control module (15), a diagnostic and evaluation module (17) and a report generation module (37).
The connection authentication module (11) evaluates whether to grant access to mobile devices (30).
The connection authentication module (11) is able to search and compare the ID and password for the worker to whom the mobile device (30) belongs to allow the worker to login and logout, and can request a level of security at a pre-set level on the mobile device (30) additionally, and if this security level is not met, may also block access by the mobile device (30).
The send/receive module (13) sends and receives data to and from multiple mobile devices (30) through wired and wireless networking.
The control module (15) extracts from the database (20) and transmits task information corresponding to the identifying information of the new renewable energy equipment unit (100) which is to be inspected to the mobile device (30) for which a connection has been granted, and receives the inspection results information on the inspection items from the mobile device (30) and saves it in the database (20).
The diagnostic and evaluation module (17) evaluates the inspection results information against the inspection standards set for each inspection item and requests re-input from the mobile device (30), if determining that the information needs to be re-input.
Here, the condition of information needing to be re-input means that the inspection results information input through the mobile device (30) does not meet the input standards required for the respective inspection item and so, for example, it could mean that an item was omitted, or that the required resolution or subject for a photograph input has not been included or that something that must be input as a number has been input as text, or vice versa.
For this, the worker re-performs the diagnostic work for the inspection items for which re-input is being requested through the mobile device (30) and re-inputs inspection results information that meets the input requirements.
Therefore, the diagnostic and management method for new renewable energy equipment units using mobile devices based on the present invention can maximize diagnostic efficiency by providing real-time feedback on information input when a worker inputs diagnostic results about equipment on-site so as to achieve diagnostic performance at a certain minimum level or above regardless of the skill level of the worker and without the need to revisit the site in order to re-diagnose items input in error.
On the other hand, an abnormal condition means the diagnostic and evaluation module has compared inspection results information that meets the input conditions against normal condition range values for the inspection results that have been preset and saved and determined that this inspection results information does not meet normal conditions or that there has been a failure.
In this case, the control module (15) transmits and displays the evaluation results for the diagnostic and evaluation module (17) through the send/receive module (13) to the mobile device (30).
Also, the control module (15) can extract repair instructions information from the database (20) which includes information on specific causes, severity level information and/or information on how to respond that has been pre-set for the respective inspection items determined to be in an abnormal condition, and transmit this repair instructions information to the mobile device (30).
The repair instructions information is classified and graded depending on the type and extent of the failure condition (specifically, whether it is rust, scratches, wear or corrosion) and severity level information (grades 1,2,3 and 4) when abnormal conditions occur in specific inspection items, and this makes it easy for workers to report on abnormal conditions and for diagnostic managers to perform quantitative and qualitative analysis of the abnormal conditions, thus maximizing diagnostic efficiency. Also, optimal ways of dealing with issues are proposed depending on the type and extent of the failure mode, making it possible to immediately respond quickly and correctly on-site.
Repair instructions information can have new items and grades added and be continuously updated by being edited by multiple workers.
On the other hand, the control module (15) receives from the mobile device (30) the repair results information that is optionally or additionally input based on the repair instructions information, including information on specific causes, severity level information, worker comment information and/or information on how to respond, and can update this information to the inspection results information and repair instructions information.
For example, if the response method that the worker performed on-site was not proposed in the repair instructions information, the worker can input the way he/she responded through worker comment information so that the diagnostic manager can add and provide this method for future repair instructions information.
Therefore, the system is able to provide optimal solutions by updating and providing additional ways of responding to on-site situations.
In addition to determinations made by the diagnostic and evaluation module (17), determinations of abnormal conditions can also be made directly by workers based on the situations on-site, and in this case, the system can be switched to failure mode and repair results information can be generated that includes information on specific causes, severity levels information and information on ways of responding to the respective inspection items.
Therefore, based on the diagnostic and management method for new renewable energy equipment units using mobile devices under the present invention, diagnostic results input by workers are transmitted to and saved on the diagnostic server in real-time so that when abnormal conditions occur on-site, the failure information, including information on specific causes and severity levels, is transmitted immediately to the diagnostic server so that the analysis of and methods of responding to the respective failures can be transmitted to the workers, making it possible to respond quickly and precisely to failures.
The control module (15) can extract same-model identifying information from the database (20) for other new renewable energy equipment units (100) having same-model identifying information as the new renewable energy equipment unit (100) exhibiting the abnormal condition inspection item information and change whether inspection items under the task information evaluated to be in an abnormal condition and corresponding to each unit of identifying information are mandatory, change their inspection priority and/or change their inspection schedule.
In other words, if multiple workers report the same abnormal condition on the same inspection items for certain new renewable energy equipment (100), this means that the equipment can be expected to exhibit weakness on certain inspection items, thus making it necessary to exercise special management of the respective inspection items in order to achieve stable operation of the overall equipment units.
Therefore, the control module (15) can edit the task information that includes the inspection items to make inspection items mandatory, raise their priority or shorten their inspection schedule.
Furthermore, the control module (15) can transmit the inspection item information, inspection results information and repair results information of the abnormal condition through the send/receive module (13) to the mobile devices (30) of other workers inspecting new renewable energy equipment units (100) having same-model identifying numbers.
In this case, by quickly propagating information about problems to workers performing diagnostic work on the same new renewable energy equipment (100) onsite in real-time, other workers can focus their diagnostic work on the respective inspection items and maximize the efficiency of their diagnostic work.
The following is a description of the diagnostic and management method for new renewable energy equipment units using mobile devices based on one embodiment of the present invention, with reference to Figures 4 and 5.
First, the worker connects to the diagnostic and management server (10) using a mobile device (30) that belongs to him/her (S11). The diagnostic and management server (10) determines whether to grant a connection to the mobile device (30) (SI2) and transmits task information, including equipment information and inspection item information that corresponds to the identifying information of the new renewable energy equipment unit (100) that is to be inspected, to the mobile device (30) that was granted a connection (SI3).
Here, the identifying information of the new renewable energy equipment unit (110) is already set in the diagnostic and management server (10) depending on the work plan of the respective worker, and task information for this can be transmitted when the respective worker connects. Also, if the worker arrives on-site first and verifies the identifying information of the new renewable energy equipment unit (100) and transmits this to the diagnostic and management server (10), the task information corresponding to the respective identifying information on the diagnostic and management server (10) can be extracted from the database (20) and transmitted to the mobile device (30).
The worker performs the diagnostic work based on the task information received and transmits to the diagnostic and management server (10) through the mobile device (30) the inspection results for which the diagnostic results for each inspection item have been input (SI4).
Here, the inspection results information may be transmitted in real-time to the diagnostic and management server (10) each time each inspection item is input individually, transmitted in specific category batches, transmitted on a set transmission schedule or transmitted all at once after the diagnostic work is complete.
The diagnostic and management server (10) evaluates the inspection results information received against the inspection standards set for each inspection item (S15).
Here, the evaluation of the inspection results information may include determinations of whether the required inspection item information has been input, whether photographs have been attached for inspection items requiring images, the resolution of the attached photographs or whether the area to be photographed is included, whether the severity level of the failure has been input and/or whether the results of performing maintenance and repairs have been input.
If it is determined that the evaluation results need to be re-input, the diagnostic and management server (10) requests that the inspection results information for the respective inspection item information be re-input (SI 9).
If the evaluation results show that the inspection results information meets the inspection standards (normal input condition), the inspection results information is saved on the database (20) (SI 7). At the same time, if the system is verified to be in a normal condition, an additional inspection report can be generated on and transmitted from the mobile device (30) (SI8).
On the other hand, as illustrated in Figure 5, the evaluation of inspection results information by the diagnostic and management server (10) comprises a step of evaluating whether the inspection results information is within the normal condition range set up for each inspection item included in the inspection results information received (SI6).
In this case, the diagnostic and management server sends a request to the mobile device to input and transmit the repair results information, including information on specific causes, severity level information, worker comment information and/or information on how to respond to the respective inspection item evaluated to be in an abnormal condition (S20, S21).
Here, under the step wherein the diagnostic and management server (10) requests repair results information, the diagnostic and management server (10) may first transmit repair instructions information to the mobile device (30) that includes pre-set information on specific causes, severity level information and/or ways of responding to the respective inspection items (S20) and then the mobile device (30) may transmit repair instructions information to the diagnostic and management server (10) that includes information on specific causes, severity level information, worker comment information and/or ways of responding which are input optionally or additionally depending on the repair instructions information (S21).
After that, the diagnostic and management server (10) extracts same-model identifying information for other new renewable energy equipment units (100) having same-model identifying information as the new renewable energy equipment unit (100) exhibiting the abnormal condition inspection item information (S22), changes whether inspection items under the task information evaluated to be in an abnormal condition and corresponding to each unit of same-model identifying information are mandatory, changes their inspection priority and/or changes their inspection schedule (S23), and updates and saves the repair results information input and received from the mobile device (30) in the repair instructions information (S24).
Additionally, the diagnostic and management server (10) transmits the abnormal condition inspection item information, inspection results information and repair results information to the mobile devices (30) of other workers inspecting new renewable energy equipment unit (10) having same-model identifying information (S25).
