That is, the monitoring and diagnosis platform may be implemented in the form of a dedicated application or web page to function as an interface for providing and displaying information and data to an administrator or user, and for receiving input from an administrator or user.
[0039] FIG. 1 is a drawing illustrating a hydrogen combined charging station according to one embodiment. The hydrogen combined charging station (100) of FIG. 1 illustrates an example including a production process facility (110), a compression process facility (120), a storage process facility (130), a charging process facility (140), a computer device (150), and a network (160).
[0040] Figure 1 is an example for explaining the invention, and the number of process equipment (110, 120, 130, 140) or computer devices (150) is not limited to that shown in Figure 1.
[0041] The computer device (150) may be configured to communicate with process equipment (110, 120, 130, 140) through the network (150) to receive data from process equipment (110, 120, 130, 140) or to transmit commands for control to process equipment (110, 120, 130, 140), and to provide a monitoring and diagnostic platform to a terminal (not shown) of an administrator or user.
[0042] The computer device (150) communicating with process equipment (110, 120, 130, 140) through the network (150) means that the computer device (150) communicates with a control processor performing a process at each of the process equipment (110, 120, 130, 140), and further means communicating with at least one sensor (111, 121, 131, 141) equipped at each of the process equipment (110, 120, 130, 140). For example, the computer device (150) can receive sensing data from at least one sensor (111, 121, 131, 141) provided in each of the process equipment (110, 120, 130, 140) and can transmit a command for control to a control processor of each of the process equipment (110, 120, 130, 140).
[0043] The communication method between the computer device (150) and the process equipment (110, 120, 130, 140) (or at least one sensor (111, 121, 131, 141) provided in each of the process equipment (110, 120, 130, 140)) is not limited and may include a communication method utilizing a communication network (e.g., mobile communication network, wired internet, wireless internet, broadcasting network) that the network (160) may include, as well as short-range wireless communication between the devices. For example, the network (160) may include any one or more networks such as a PAN (personal area network), LAN (local area network), CAN (campus area network), MAN (metropolitan area network), WAN (wide area network), BBN (broadband network), and the Internet. Additionally, the network (160) may include any one or more network topologies including a bus network, a star network, a ring network, a mesh network, a star-bus network, a tree or hierarchical network, but is not limited thereto.
[0044] A hydrogen convergence charging monitoring and diagnostic system, which is the entity performing the hydrogen convergence charging monitoring and diagnostic method, may be implemented in such a computer device (150). A detailed description thereof will be provided below.
[0045] The production process equipment (110) is a facility that performs a production process to produce hydrogen using biomethane as a raw material, and may be, for example, a hydrogen extractor that produces hydrogen by electrochemical decomposition or thermal catalytic decomposition of biomethane.
[0046] The compression process equipment (120) is equipment that performs a compression process for compressing hydrogen produced in the production process equipment (110), and may be, for example, a piston-type compressor that compresses hydrogen gas. At this time, the compression process equipment (120) may be implemented with a plurality of compression process equipment (e.g., high-pressure compression process equipment and medium-pressure compression process equipment) to compress hydrogen to different pressures based on a preset critical pressure value.
[0047] The storage process facility (130) is a facility that performs a storage process for storing hydrogen compressed in the compression process facility (120), and may be, for example, a storage container for storing compressed hydrogen gas. As described above, if the compression process facility (120) is implemented as a plurality of compression process facilities (e.g., high-pressure compression process facility and medium-pressure compression process facility), the storage process facility (130) may also be implemented as a plurality of storage process facilities (e.g., high-pressure storage process facility and medium-pressure storage process facility) to correspond to the plurality of compression process facilities.
[0048] The charging process facility (140) is a facility that performs a charging process for supplying hydrogen stored in the storage process facility (130), and may be, for example, a dispenser or injection panel that supplies the stored hydrogen gas to a vehicle requiring charging.
[0049] Although the hydrogen convergence charging station has been described as an example including a production process facility (110), it is not limited to or restricted thereto and may include a tube trailer (not shown) that receives hydrogen gas produced elsewhere via a hydrogen tank vehicle instead of the production process facility (110). In such a case, the hydrogen convergence charging monitoring and diagnostic method performed at the hydrogen convergence charging station may include a transport and supply process of the tube trailer (a process of transporting and supplying hydrogen gas) instead of the production process of the production process facility (110).
[0051] FIG. 2 is a block diagram illustrating an example of a computer device according to one embodiment.
[0052] As illustrated in FIG. 2, the computer device (150) may include memory (210), a processor (220), a communication interface (230), and an input / output interface (240). The memory (210) is a computer-readable recording medium and may include a non-perishable mass storage device such as RAM (random access memory), ROM (read only memory), and a disk drive. Here, the non-perishable mass storage device such as ROM and the disk drive may be included in the computer device (150) as a separate permanent storage device distinct from the memory (210). Additionally, an operating system and at least one program code may be stored in the memory (210). These software components may be loaded into the memory (210) from a computer-readable recording medium separate from the memory (210). This separate computer-readable recording medium may include a computer-readable recording medium such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, or a memory card. In another embodiment, software components may be loaded into memory (210) via a communication interface (230) rather than a computer-readable recording medium. For example, software components may be loaded into memory (210) of a computer device (150) based on a computer program installed by files received through a network (160).
[0053] The processor (220) may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations. Instructions may be provided to the processor (220) via memory (210) or a communication interface (230). For example, the processor (220) may be configured to execute instructions received according to program code stored in a recording device such as memory (210).
[0054] The communication interface (230) may provide a function for the computer device (150) to communicate with other devices (e.g., storage devices described above) through the network (160). For example, requests, commands, data, files, etc. generated by the processor (220) of the computer device (150) according to program code stored in a recording device such as memory (210) may be transmitted to other devices through the network (160) under the control of the communication interface (230). Conversely, signals, commands, data, files, etc. from other devices may be received by the computer device (150) through the communication interface (230) of the computer device (150) via the network (160). Signals, commands, data, etc. received through the communication interface (230) may be transmitted to the processor (220) or memory (210), and files, etc. may be stored in a storage medium (the permanent storage device described above) that the computer device (150) may further include.
[0055] The input / output interface (240) may be a means for interfacing with an input / output device (250). For example, the input device may include a device such as a microphone, keyboard, or mouse, and the output device may include a device such as a display or speaker. As another example, the input / output interface (240) may be a means for interfacing with a device in which the functions for input and output are integrated into one, such as a touchscreen. The input / output device (250) may be composed of a computer device (150) and a single device.
[0056] Additionally, in other embodiments, the computer device (150) may include fewer or more components than the components of FIG. 2. However, it is not necessary to clearly illustrate most of the prior art components. For example, the computer device (150) may be implemented to include at least some of the input / output devices (250) described above, or may include other components such as a transceiver, a database, etc.
[0057] In the following, specific embodiments of the hydrogen convergence charging monitoring and diagnosis method and system, and the monitoring and diagnosis platform will be described.
[0059] FIG. 3 is a block diagram illustrating examples of components that may be included in the processor shown in FIG. 2, and FIG. 4 is a flowchart illustrating a hydrogen fusion charging monitoring and diagnostic method that the computer device shown in FIG. 2 can perform.
[0060] In the embodiments, the computer device (150) performs a hydrogen convergence charging monitoring and diagnosis method, thereby monitoring each of the production process, compression process, storage process, and charging process in real time, diagnosing each of the production process, compression process, storage process, and charging process based on the results, and then providing the diagnosis results to a manager or user's terminal through a monitoring and diagnosis platform. To this end, the computer device (150) may be configured with a hydrogen convergence charging monitoring and diagnosis system that is the entity performing the hydrogen convergence charging monitoring and diagnosis method. For example, the hydrogen convergence charging monitoring and diagnosis system may be implemented in the form of an independently operating program, or configured as an in-app of a dedicated application so that it can operate on the dedicated application.
[0061] The processor (220) of the computer device (150) may be implemented as a component for performing the dynamic risk prediction method according to FIGS. 4 and 5. For example, the processor (220) may include a monitoring unit (310) and a diagnostic unit (320) as shown in FIG. 3 so as to be able to perform the steps (S410 to S420) shown in FIG. 4. Depending on the embodiment, the components of the processor (220) may be optionally included in or excluded from the processor (220). Additionally, depending on the embodiment, the components of the processor (220) may be separated or merged to represent the function of the processor (220).
[0062] These processors (220) and components of the processor (220) can control a computer device (150) to perform steps (S410 to S420) included in the hydrogen fusion charging monitoring and diagnostic method of FIG. 4. For example, the processor (220) and components of the processor (220) may be implemented to execute instructions according to the code of an operating system included in the memory (210) and the code of at least one program.
[0063] Here, the components of the processor (220) may be representations of different functions performed by the processor (220) according to instructions provided by program code stored in the computer device (150). For example, a diagnostic unit (320) may be used as a functional representation of the processor (220) that controls the computer device (150) to diagnose each of the production process, compression process, storage process, and charging process based on the results of monitoring.
[0064] The processor (220) can read necessary commands from memory (210) in which commands related to the control of the computer device (150) are loaded. In this case, the read commands may include commands to control the processor (220) to execute steps (S410 to S420) to be described later.
[0065] The steps (S410 to S420) to be described later may be performed in a different order than the order shown in FIG. 4, and some of the steps (S410 to S420) may be omitted or additional processes may be included.
[0066] In step (S410), the processor (220) (more precisely, the monitoring unit (310) included in the processor (220)) can monitor the production process, compression process, storage process, and charging process in real time using at least one sensor (111, 121, 131, 141) provided in each of the production process equipment (110), compression process equipment (120), storage process equipment (130), and charging process equipment (140).
[0067] More specifically, the processor (220) (more precisely, the monitoring unit (310) included in the processor (220)) can monitor the sensing data of each of the production process, compression process, storage process, and charging process in real time by collecting sensing data from at least one sensor (111, 121, 131, 141) provided in each of the production process equipment (110), compression process equipment (120), storage process equipment (130), and charging process equipment (140).
[0068] In step (S420), the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) can diagnose each of the production process, compression process, storage process, and charging process in real time based on the results monitored through step (S410). The diagnostic results can be provided to a manager or user's terminal through a monitoring and diagnostic platform.
[0069] In the following, diagnosing each of the production process, compression process, storage process, and charging process may mean predicting and diagnosing the status of each of the production process, compression process, storage process, and charging process, evaluating the risks of each of the production process, compression process, storage process, and charging process, or evaluating the hydrogen productivity, hydrogen shipment volume, economic feasibility, or profitability of the hydrogen convergence charging including the production process, compression process, storage process, and charging process.
[0070] To explain the prediction and diagnosis of the state of each of the production process, compression process, storage process, and charging process in step (S420), the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) can predict and diagnose the state of each of the production process, compression process, storage process, and charging process by analyzing the sensing data collected from at least one sensor (111, 121, 131, 141) equipped in each of the production process facility (110), compression process facility (120), storage process facility (130), and charging process facility (140) using a multivariate regression analysis ensemble algorithm based on Partial Least Squares (PLS) regression analysis, Dynamic Principal Component Analysis (DPCA) technique, and Nearest Neighbor (k-NN) model.
[0071] For example, the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) may apply a PLS regression analysis technique to improve the modeling accuracy of sensing data collected from at least one sensor (111, 121, 131, 141) equipped in each of the production process equipment (110), compression process equipment (120), storage process equipment (130), and charging process equipment (140), by analyzing the principal components of the sensing data, estimating the dependent variable value through the independent variable value, and performing regression analysis from the dependent variable value to check the prediction error. In addition, the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) may apply a DPCA technique for data analysis considering time and space, and may apply a k-NN model to ensure the reliability of the sensing data.
[0072] At this time, the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) may use a multivariate regression ensemble algorithm by considering the season, weather, time, and the operating mode and component information of each of the production process equipment, compression process equipment, storage process equipment, and charging process equipment in order to improve prediction accuracy. To this end, the multivariate regression ensemble algorithm may be pre-learned using the sensing data of each of the production process equipment (110), compression process equipment (120), storage process equipment (130), and charging process equipment (140) as input data in a learning environment of various seasons, weather, time, operating modes, and component information.
[0073] Additionally, the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) can calculate the causal relationships and contributions of sensing data for each of the predicted and diagnosed production process, compression process, storage process, and charging process in order to improve prediction accuracy. The calculated causal relationships and contributions can be used in the process of predicting and diagnosing the next production process, compression process, storage process, and charging process.
[0074] The status of each of the predicted and diagnosed production, compression, storage, and charging processes can be visualized through a monitoring and diagnostic platform and provided to a manager's or user's terminal.
[0075] Additionally, the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) can further provide information related to the quality and recommended process execution patterns of each of the production process, compression process, storage process, and charging process, based on the predicted and diagnosed state of each of the production process, compression process, storage process, and charging process, to the terminal of the manager or user through the monitoring and diagnostic platform.
[0076] To explain the evaluation of the risk of each of the production process, compression process, storage process, and charging process in step (S420), the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) can evaluate the risk of each of the production process, compression process, storage process, and charging process based on the predicted accident frequency and death number in each of the production process, compression process, storage process, and charging process by predicting the accident frequency and death number in each of the production process, compression process, storage process, and charging process.
[0077] For example, the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) can evaluate the risk of the AIR (Average Individual Ratio) for each of the production process, compression process, storage process, and charging process through the following Equations 1 to 3 based on the accident frequency and number of fatalities in each of the predicted production process, compression process, storage process, and charging process.
[0079] <Equation 1>
[0080]
[0081] <Equation 2>
[0082]
[0083] <Equation 3>
[0084]
[0086] In Equations 1 to 3 represents the accident frequency for the nth process equipment, and represents the predicted number of deaths at the nth process facility, and represents the process execution time of the nth process equipment, and represents the amount of time an individual spends at a hydrogen convergence charging station annually.
[0087] In hydrogen fusion charging, there exists a process with a relatively higher risk due to the characteristics of each process. Therefore, the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) can evaluate the risk by further subdividing the compression process and storage process, which have a higher risk due to process characteristics or statistically. For example, as described above, the compression process equipment (120) and storage process equipment (130) are each equipped with multiple compression process equipment (e.g., medium-pressure compression process equipment and high-pressure compression process equipment) and storage process equipment (e.g., medium-pressure storage process equipment and high-pressure storage process equipment) to compress and store at different pressures based on at least one preset threshold pressure value. Accordingly, the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) can classify the compression process and storage process into multiple compression processes and multiple storage processes based on at least one preset threshold pressure value, and evaluate the risk for each of the classified compression processes and storage processes.
[0088] Additionally, risk assessment may be performed for only selected parts instead of all production, compression, storage, and charging processes. For example, a processor (220) (specifically, a diagnostic unit (320) included in the processor (220)) can select at least one process showing an abnormal state among the production, compression, storage, and charging processes based on sensing data collected from at least one sensor (111, 121, 131, 141) provided in each of the production process facility (110), compression process facility (120), storage process facility (130), and charging process facility (140), and then predict the accident frequency and number of deaths in the selected at least one process, thereby assessing the risk in the selected at least one process based on the predicted accident frequency and number of deaths in the selected at least one process.
[0089] In step (S420), the hydrogen productivity, hydrogen shipment volume, economic feasibility, or profitability of a hydrogen composite charging system including a production process, a compression process, a storage process, and a charging process is evaluated. The processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) can evaluate the hydrogen productivity, which is the amount of hydrogen produced, the hydrogen shipment volume, and the economic feasibility or profitability based on sensing data collected from at least one sensor (111, 121, 131, 141) provided in each of the production process facility (110), the compression process facility (120), the storage process facility (130), and the charging process facility (140).
[0090] Here, economic feasibility or profitability is evaluated based on sensing data collected from at least one sensor (111, 121, 131, 141) equipped in each of the production process facility (110), compression process facility (120), storage process facility (130), and charging process facility (140), because economic feasibility or profitability is calculated by taking into account the maintenance of the hydrogen composite charging. More specifically, the processor (220) (more precisely, the diagnostic unit (320) included in the processor (220)) derives the hardware cost of hydrogen fusion charging based on the state of each of the production process, compression process, storage process, and charging process, which is predicted and diagnosed based on sensing data collected from at least one sensor (111, 121, 131, 141) equipped in each of the production process facility (110), compression process facility (120), storage process facility (130), and charging process facility (140), and then evaluates economic feasibility by calculating the Benefit Cost Ratio (B / C Ratio), Net Present Value (NPV), or Internal Rate of Return (IRR) using a Cost-Benefit Analysis method based on the derived hardware cost, or evaluates economic feasibility by calculating the Net Present Value Method, Internal Rate of Return Method, or profitability index based on the derived hardware cost Profitability can be evaluated using the Profitability Index Method.
