Description

Explosion-proof management system

[0001] The present invention relates to an explosion-proof management system, and more particularly, to an explosion-proof management system that collects data such as information and equipment information of specific locations exposed to explosion risks, such as power generation facilities, gas, petrochemical, and marine plants, and reports and notifies the user, thereby preventing the occurrence of safety accidents in advance through history management, inspection cycle management, and prevention of information omission due to updates, while facilitating the search for explosion-proof equipment required for purchase.

[0002] In general, nuclear power plants, gas plants, petrochemical plants, marine plants, etc. refer to industries that supply facilities or build factories that can produce products such as electricity, gas, and petrochemicals, and refer to devices, factory facilities, or production facilities that supply raw materials or energy to obtain energy and cause physical and chemical reactions. Plant facilities are mostly classified as high-risk facilities because many important facilities are densely packed in a large space.

[0003] Furthermore, given that a significant portion of Korea's plant facilities were built in the 1960s and 1970s and are aging, decisions regarding decommissioning, maintenance, and replacement are urgent. Therefore, most plant facilities are high-risk facilities containing hazardous materials, requiring continuous monitoring and management. In the event of equipment failure or damage, it's crucial to quickly locate the equipment and respond as quickly as possible.

[0004] In particular, high-risk facilities such as nuclear power plants, gas plants, petrochemical plants, and marine plants must conduct regular preventive maintenance, and if gas or chemical substances leak, it can cause large-scale fires and explosions, so response measures must be taken promptly.

[0005] Countless measuring devices that perform monitoring functions within these high-risk facilities are installed close to pipes and facilities, which can affect the high-risk facilities in the event of a fire or explosion accident due to electrical failure or external impact of the measuring devices. Therefore, non-explosion-proof measuring monitoring systems cannot be used, and the systems are built by installing the systems in separate explosion-proof enclosures. However, installing them in separate explosion-proof enclosures increases installation costs, weakening competitiveness and causing space constraints.

[0006] Additionally, when certain conditions change, such as changes in specific locations or equipment of high-risk facilities or changes in gas usage, this must always be reviewed and information updated. If this process is not carried out and information is omitted or falsely entered, it may cause an explosion accident.

[0007] Accordingly, in order to prevent the above-mentioned problems, a technology has been applied for which provides a safety inspection solution for explosion-proof diagnosis, thereby enabling the collection of correct information on high-risk facilities to prevent omissions and misjudgments due to false information or mistakes.

[0008] Plant managers and personnel responsible for safety management must purchase explosion-proof products during the plant's design and maintenance stages. This is especially true during the maintenance phase, where changes to existing products may occur, and various obstacles, such as product discontinuations, product changes, supplier changes, and business closures, pose challenges in purchasing explosion-proof products.

[0009] Korean Patent No. [10-2517384] discloses a smart platform for explosion-proof inspection at industrial sites.

[0010] Accordingly, the present invention has been devised to solve the above-mentioned problems, and the purpose of the present invention is to provide an explosion-proof management system that collects data such as information and equipment information of specific locations exposed to the risk of explosion, such as power generation facilities, gas, petrochemical, and marine plants, and reports and notifies, thereby preventing the occurrence of safety accidents in advance through history management, inspection cycle management, and prevention of information omission due to updates, and at the same time facilitates the search for explosion-proof equipment required for purchase.

[0011] The purpose of the embodiments of the present invention is not limited to the purpose mentioned above, and other purposes not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

[0016] In addition, the explosion-proof management system is characterized by including a change management support unit (200) that outputs a list of equipment that needs to be replaced among the equipment already installed in the area when a change occurs in the information set in the risk zone setting unit (60) to enable replacement of the equipment.

[0017] In addition, the change management support unit (200) is characterized by recommending replaceable equipment that matches the changes in information set in the risk zone setting unit (60) with respect to the list of equipment requiring replacement displayed on the screen.

[0018] In addition, the explosion-proof management system includes a barrier that performs an automatic blocking function when an electrical hazard occurs, and is characterized by including an intrinsic safety management unit (300) that reviews a design that satisfies electrical parameter matching by considering the barrier cable explosion-proof device when at least one situation selected from among a barrier change, a cable replacement, and a field device change occurs.

[0019] In addition, the intrinsic safety management unit (300) is characterized in that it determines that a normal design has been achieved if all input and output side requirements for voltage, current, power, capacitance, and inductance are satisfied based on the barrier for each circuit.

[0020] Also, the above input and output side requirements are

[0054] Before the explanation, let us briefly explain the terms used in this specification (and patent claims).

[0055] A 'User' is a person in charge or responsible for a plant and can perform explosion-proof safety management through an explosion-proof management system according to one embodiment of the present invention. For this purpose, an account is provided in the explosion-proof management system according to one embodiment of the present invention.

[0056] A 'Supplier' is a supplier (may be a manufacturer) that supplies explosion-proof products, conducts sales and distributes promotional materials to supply products to plants, and may be assigned an account in the explosion-proof management system according to one embodiment of the present invention.

[0057] Although basic terms are summarized, not all terms necessary for explanation are summarized. New variables and terms that appear in addition to the terms defined above will be explained later.

[0058] As illustrated in FIG. 1, an explosion-proof management system according to one embodiment of the present invention includes an interface unit (10), an output unit (20), a database management unit (30), a control unit (40), an inspection unit (50), a risk zone setting unit (60), an installation design support unit (70), a field installation support unit (80), an approval unit (90), and a suitable equipment recommendation unit (100).

[0059] The interface section (10) receives information according to explosion-proof testing input through the terminal.

[0060] The interface section (10) allows various information, such as paths, equipment history, and inspection reports, to be input through the terminal.

[0061] The output unit (20) processes information input from the interface unit (10) and outputs it to the terminal.

[0062] The output section (20) performs the function of transmitting information to the user by outputting various information such as paths, equipment history, and inspection reports through the terminal.

[0063] At this time, the output unit (20) can be configured to provide notification through various configurations such as vibration, LED, speaker, and display.

[0064] The database management unit (30) stores information necessary for conducting explosion-proof inspection.

[0065] The database management unit (30) stores information necessary for conducting explosion-proof inspections, and stores data such as information on specific locations, such as maps of explosion-hazardous areas or the structure (space) of buildings, and information on specific equipment, such as the name, manufacturer, installation date, and replacement cycle of the equipment.

[0066] It is desirable that the database management unit (30) update the stored information in real time, and the information entered through the interface unit (10) is updated and stored.

[0067] At this time, the terminal can be configured to determine whether there has been input of information that is updated in real time.

[0068] For example, after detecting a change in the location of a terminal through GPS based on information about a specific location stored in the database management unit (30), it is inferred whether an inspection was conducted at a location where the terminal stayed for a certain period of time, and if it is determined that an inspection was conducted, it is possible to determine whether the inspection results were updated in real time through the interface unit (10), thereby enabling confirmation of whether any information update omission occurred after the inspection.

[0069] That is, if the database management unit (30) is not updated in real time after an inspection is performed on a specific piece of equipment at a specific location, it is considered that the information has not been updated after the inspection, and the user is notified through the output unit (20), thereby preventing omissions due to information updates.

[0070] Here, inferring whether the inspection was conducted at a location where the terminal (100) stayed for a certain period of time means the time learned through a deep learning algorithm.

[0071] To elaborate, the movement of the terminal is detected by GPS, and the time the terminal remains in a specific location where specific equipment is installed is detected. If the time the terminal remains in that location (i.e., the time it remains stationary without moving) is longer than the minimum time required to inspect a specific piece of equipment at that location, it can be inferred that the equipment has been inspected.

[0072] That is, if the terminal stays in a specific location for a longer period of time than the minimum time required for inspection, it can be assumed that inspection of a specific device has been performed, and real-time updates can be performed to prevent the problem of inspection results not being updated.

[0073] The control unit (40) controls the flow of data to and from the terminal.

[0074] The control unit (40) is for controlling the flow of data between the terminal and the explosion-proof management system according to one embodiment of the present invention, and performs a control function of the entire explosion-proof management system according to one embodiment of the present invention.

[0075] The inspection department (50) performs the function of supporting the inspection of explosion-proof equipment.

[0076] The inspection department (50) performs the function of supporting inspection of specific areas and equipment.

[0077] The risk zone setting unit (60) determines the level and range of the risk zone for explosion.

[0078] The risk zone setting unit (60) performs the function of determining the level and range of the risk zone of explosion in a combustible gas and dust environment, and can determine the dilution level, confirm the level of the explosion-proof zone, and output the risk zone distance through the output unit (20).

[0079] First, identify the location of use of flammable gas and the source of the leak within the explosion hazard area, and detect the amount of gas leaking from the leaking area.

[0080] Afterwards, ventilation information for a specific area is divided into outdoor and indoor, and the ventilation speed (ventilation performance) is determined based on the divided results.

[0081] At this time, for a specific area determined as Outdoor, the specified ventilation speed value is output, and for a specific area determined as Indoor, the ventilation speed is determined after distinguishing between natural ventilation and forced ventilation.

[0082] Accordingly, the dilution level is determined based on the ventilation speed determined in the specific area, the explosion-proof zone is registered, and the danger zone distance is calculated, which can be output through the output unit (20).

[0083] Accordingly, the user can receive information on the range within the hazard zone and the level of flammable gas and dust environment through the terminal, enabling customized ventilation of the specific area and providing information on the range within the hazard zone.

[0084] The installation design support unit (70) ensures that explosion-proof equipment is installed based on the ID of the equipment registered in the database management unit (30), the explosion risk zone class determined in the risk zone setting unit (60), the gas group, and the temperature class.

[0085] The installation design support department (70) performs the function of supporting the proper installation of equipment in explosion-proof areas.

[0086] At this time, it is desirable that the information of the equipment to be installed within the explosion risk area be registered in the database management unit (30), and further, an individual ID may be assigned to each equipment, and cable connection information may be stored together.

[0087] This allows the user to determine whether the equipment can be installed in a specific explosion hazard area or whether the risk of safety accidents is high or low by having the electrical and communication circuit diagrams of the equipment output together when the user attempts to view the ID of the equipment through the terminal.

[0088] In detail, the installation of equipment can be performed correctly based on various information such as the explosion risk zone grade, gas group, and temperature grade of a specific area determined in the above risk zone setting unit (60).

[0089] Here, the Gas Group refers to identifying the characteristics of the gases expected to be present where the equipment is to be installed and ensuring that the correct equipment is installed based on the identified results.

[0090] To elaborate, since the Gas Group includes a wide variety of gases, gases with similar characteristics can be grouped together by considering the characteristics of each gas, and this can be based on classification standards such as the IEC classification standard.

[0091] Additionally, the temperature rating refers to the temperature at which the object begins to ignite.

[0092] The on-site installation support department (80) compares the results output from the installation design support department (70) with the information on the installed explosion-proof equipment to determine suitability.

[0093] The field installation support department (80) performs the function of supporting the field installation of explosion-proof equipment.

[0094] This, together with the installation design support department (70), allows for real-time inspection to ensure that the installation of the equipment is being carried out correctly during actual equipment installation.

[0095] At this time, customized information can be provided based on the ID of the selected equipment through the terminal to ensure that installation is carried out in compliance with electrical safety standards, construction regulations, explosion-proof regulations, etc.

[0096] For example, if a user wants to install equipment in an explosion risk area, the installation can be carried out by receiving information through the on-site installation support department (80), thereby enabling real-time inspection.

[0097] At this time, in order to determine whether there was any omission in the ID verification or information verification of the actual equipment or whether the equipment was installed correctly, the user can use the terminal to register and inspect the installed equipment from the RFID tag, and output an installation report accordingly.

[0098] In addition, when cable information of the installed equipment is entered, it can be configured to determine suitability by comparing it with the information provided by the installation design support unit (70).

[0099] The approval department (90) permits the installation or inspection of explosion-proof equipment.

[0100] The approval unit (90) has a function for permitting installation or inspection of equipment, and has the function of allowing approval from the explosion-proof management system according to one embodiment of the present invention when various tasks are performed by a user who owns a terminal in the field.

[0101] This approval unit (90), as described with reference to FIG. 2, is configured to ensure that the process of installing, inspecting, maintaining or repairing equipment requires approval of the explosion-proof management system according to one embodiment of the present invention, and can be configured to notify when work is performed without approval.

[0102] This is because, if various tasks are performed without approval, information updates may be omitted, and if the actual equipment history and the data history information are different, safety accidents may easily occur. Therefore, to prevent this, it is desirable to ensure that tasks are performed only after approval is obtained from the explosion-proof management system according to one embodiment of the present invention before the task is performed.

[0103] For example, in order to approve a task, the inspection cycle of the equipment in question can be identified, whether the equipment falls within the inspection cycle can be identified, and then the user can be notified of this via the terminal, thereby allowing the task to be approved.

[0104] Depending on the design conditions, the approval unit (90) may be configured to require the user to obtain approval for starting work before starting work, and to obtain approval again when the work is completed so that the user's work start time, end time, and data on the work content are correctly updated.

[0105] The suitable equipment recommendation section (100) includes information on explosion risk areas and recommends applicable explosion-proof equipment based on a matching of explosion-proof information including at least one additional item selected from gas, dust, and temperature and explosion-proof equipment information provided by an explosion-proof equipment manufacturer.

[0106] For example, the above-mentioned suitable equipment recommendation unit (100) may select equipment installed in an area from the plant on the terminal screen of the purchaser (User) shown by the above-mentioned output unit (20) and then execute equipment selection, and then perform a matching (comparison) process with the area information requirements, and then recommend equipment with the same information as the selected equipment. If there is no identical equipment, equipment with high similarity may be recommended.

[0107] As another example, the above-mentioned suitable equipment recommendation unit (100) can guide the user to select an equipment type when the user selects an area from the plant on the terminal screen shown by the output unit (20) and then executes equipment selection, and can recommend equipment that matches this information.

[0108] The above suitable equipment recommendation unit (100) can provide searched results by sorting them based on recommendation criteria such as price, latest products, and popular products.

[0109] Explosion risk area information may include explosion risk area class information, gas information may include gas group information, dust information may include dust group information, and temperature information may include temperature class (T-Class) information.

[0110] Explosion hazard zone rating information can be divided into Zone 0, Zone 1, Zone 2, Safe area, Zone 20, Zone 21, and Zone 22 according to the IEC classification standards.

[0111] Gas Group information can be categorized into IIA, IIB, IIC, etc. depending on the flammability of the substance.

[0112] Dust Group information can be classified into IIIA, IIIB, and IIIC depending on the combustibility of the environment.

[0113] Temperature rating (T-Class) information can be classified into T1, T2, T3, T4, T5, T6, N / A, etc. based on the autoignition temperature of combustible gas in the installation environment.

[0114] Explosion-proof equipment information may include EPL (Equipment Protection Level) information, and EPL (Equipment Protection Level) information can be classified as Ga, Gb, Gc, Da, Db, Dc, N / A, etc.

[0115] For example, if the explosion hazard zone rating is Zone 0, explosion-proof equipment with EPL (Equipment Protection Level) information of Ga can be used, if the explosion hazard zone rating is Zone 1, explosion-proof equipment with EPL (Equipment Protection Level) information of Ga and Gb can be used, if the explosion hazard zone rating is Zone 2, explosion-proof equipment with EPL (Equipment Protection Level) information of Ga, Gb and Gc can be used, if the explosion hazard zone rating is Zone 20, explosion-proof equipment with EPL (Equipment Protection Level) information of Da can be used, if the explosion hazard zone rating is Zone 21, explosion-proof equipment with EPL (Equipment Protection Level) information of Da and Db can be used, if the explosion hazard zone rating is Zone 22, explosion-proof equipment with EPL (Equipment Protection Level) information of Da, Db and Dc can be used, if the explosion hazard zone rating is Safe area, explosion-proof equipment with EPL (Equipment Protection Level) information of Ga, Gb, Gc, Da, Explosion-proof equipment of Db, Dc, and N / A can be used.

[0116] The list of explosion-proof equipment searched and recommended through the above-mentioned suitable equipment recommendation unit (100) allows buyers to select and register products of interest. The explosion-proof management system according to one embodiment of the present invention can provide a product comparison function for information on various registered products. In this case, an optimization algorithm based on machine learning technology can be applied.

[0117] An explosion-proof management system according to one embodiment of the present invention provides a platform that matches sellers (Supplier) and buyers (User) by identifying information on explosion-proof equipment and devices, explosion-proof parts, etc. on a cloud-based platform.

[0118] In addition, the purchaser (User) must select a certified product at the design stage and reflect it in the design, which is supported by the explosion-proof management system according to one embodiment of the present invention.

[0119] In addition, the purchaser (User) must find, select, and purchase the relevant product when repairs, replacements, etc. occur during the maintenance stage, and this is supported by the explosion-proof management system according to one embodiment of the present invention.

[0120] As illustrated in FIG. 3, the suitable equipment recommendation unit (100) of the explosion-proof management system according to one embodiment of the present invention may include a product registration unit (110), a search condition input unit (120), and a search unit (130).

[0121] The product registration section (110) receives, stores and manages product information including explosion-proof equipment information for products that the seller wishes to sell.

[0122] The above sales product information may include information such as model name, product type, product specifications, certification, customer drawings, instructions, and EPL (Equipment Protection Level).

[0123] The search condition input section (120) receives purchase product information including explosion-proof information of the product the buyer wishes to purchase.

[0124] The above purchased product information may include information on installed explosion-proof equipment, explosion hazard zone class, gas group, dust group, temperature class (T-Class), equipment group, protection type, equipment protection level (EPL), and power source.

[0125] Equipment group information can be categorized as I, II, III, etc.

[0126] Protection type information can be classified into Ex d, Ex p, Ex o, Ex q, Ex e, Ex i, Ex n, Ex m, Ex op, Ex t, Ex s, etc.

[0127] Power source information can be categorized into three-phase, single-phase, voltage, etc.

[0128] The above search condition input section (120) can display the purchase product information on a screen that the buyer can check, and can receive basic purchase product information by entering the buyer's check.

[0129] The search unit (130) searches for applicable explosion-proof equipment based on the matching of the sales product information stored in the product registration unit (110) and the purchase product information entered in the search condition input unit (120).

[0130] For example, the purchaser can select an existing explosion-proof equipment from an explosion-proof zone map and search for identical or similar explosion-proof equipment that can replace the existing explosion-proof equipment.

[0131] As another example, you can input the type of explosion-proof equipment (e.g., lamp), explosion hazard zone rating (e.g., Zone 0), gas group (e.g., IIA), and temperature rating (e.g., T1) and search for explosion-proof equipment that satisfies the conditions.

[0132] The search unit (130) of the explosion-proof management system according to one embodiment of the present invention may be characterized by additionally searching for explosion-proof equipment registered in the IECEx online system and providing the results.

[0133] IECEx is the International Electrotechnical Hazard Classification and Assessment System, which provides international standards to ensure the safety of electrical and electronic equipment used in potentially explosive environments.

[0134] The IECEx On-line System is an online platform that manages and provides IECEx certification and related information. Products that have received IECEx certification can be searched on the IECEx On-line System.

[0135] As illustrated in FIG. 3, the suitable equipment recommendation unit (100) of the explosion-proof management system according to one embodiment of the present invention may include a recommendation unit (140) that assigns priorities according to the purchaser's requirements among the search results of the search unit (130) and recommends explosion-proof equipment based on the priorities.

[0136] The above recommendation unit (140) can determine the priority based on the comprehensive risk (Risk) calculated by multiplying the comprehensive risk level (RL_Area) related to explosion-proof information and the comprehensive risk level (RL_Eq) of explosion-proof equipment information.

[0137] Explosion-related variables that can be applied to calculating the comprehensive risk level (RL_Area) related to explosion-related information (e.g., 10-point scale) include environmental conditions, explosion hazard zone rating (Zone), explosion consequences, inspection frequency, risk score (Plant History), and fault trends of site.

[0138] Explosion-proof equipment information-related variables that can be applied to calculating the comprehensive risk level (RL_Eq) of explosion-proof equipment information (e.g., 10-point scale) include equipment type (risk level varies depending on type), risk grade according to voltage, and number of special conditions.

[0139] The comprehensive risk calculated in this way can be applied through an adjustment process depending on the results.

[0140] For example, the comprehensive risk (Risk) can be calculated by multiplying the comprehensive risk level (RL_Area) for explosion-proof information and the comprehensive risk level (RL_Eq) for explosion-proof equipment information. If the score is 25 or higher, the safety margin (Safety Margin) can be reflected by more than 50%. Furthermore, if each score is 8 or higher, the safety margin can be reflected by more than 50%.

[0141] That is, the above recommendation unit (140) can determine the priority by additionally reflecting recommendation criteria such as economic feasibility, safety (Safety Margin), availability of stock (Location of production), and delivery condition (Delivery condition) by applying a machine learning optimization algorithm.

[0142] In other words, if there are multiple recommendation criteria to be applied, the comprehensive score can be calculated and used to make recommendations.

[0143] At this time, a comprehensive score can be calculated by assigning a weight to each evaluation result according to each recommendation criterion.

[0144] In terms of economic feasibility, the lower the price, the higher the safety. A "-" (negative) result indicates a higher price.

[0145] That is, within the economic optimization algorithm, the price of a product can be classified based on a sign to determine whether it is high or low compared to existing products, and information can be provided to buyers (users) by marking it so that it can be identified.

[0146] The formula used in the economic optimization algorithm is as follows.

[0147]

[0148] - Score (P): Price score

[0149] - P: Price

[0150] - P1: Price of existing installed product

[0151] - P2: Price of the searched product

[0152] In terms of safety, the higher the price, the higher the economic efficiency.

[0153] The formula used in the safety optimization algorithm is as follows.

[0154]

[0155] - Score (S): Safety Margin Score

[0156] - Wz: Zone weight

[0157] - WG: Group Weight

[0158] - WT: T-Class weight

[0159] - Score (Z): Score for Zone

[0160] - Score (G): Score for the group

[0161] - Score (T): T-Class weight

[0162] Here, Score (Z), Score (G), and Score (T) can be given different weights depending on the difference in grade, such as 1.0 for the same grade, 1.2 for the top 1st grade, 1.4 for the top 2nd grade, 1.6 for the top 3rd grade, 1.8 for the top 4th grade, and 2.0 for the top 5th grade or higher.

[0163] As illustrated in FIG. 4, the explosion-proof management system according to one embodiment of the present invention may include a change management support unit (200) that outputs a list of equipment that needs to be replaced among the equipment already installed in the corresponding area when a change occurs in the information set in the risk zone setting unit (60) to enable replacement of the equipment.

[0164] The above change management support unit (200) performs the function of deriving equipment items that are unsuitable for use when the zone-specific setting values ​​set in the above risk zone setting unit (60) are changed.

[0165] For example, when the explosion hazard zone rating of a specific area changes from Zone 2 to Zone 1 due to a process change, equipment with an EPL (Equipment Protection Level) of Gc among the already installed equipment can be identified as non-conforming items, and a list of Gb equipment that can be replaced can be output.

[0166] In the case of large-scale sites, thousands of types of equipment are installed, and if there are n evaluation items per type of equipment, a large amount of computational capacity may be required, so efficient comparison logic and search logic are required.

[0167] Therefore, we can prioritize the search comparison.

[0168] For example, it could be a way to compare only the changed items.

[0169] Therefore, when information is changed, the log can be designated as a variable and the installed equipment can be sequentially searched and compared, but only the designated variable items can be compared and calculated to determine any non-conformities.

[0170] Once the evaluation of the equipment is complete, you can output the non-conforming items and move on to evaluating the next equipment.

[0171] Once the comparison is performed on all the equipment in that area, a list can be printed.

[0172] The change management support unit (200) of the explosion-proof management system according to one embodiment of the present invention may be characterized by recommending replaceable equipment that matches the changes in information set in the risk zone setting unit (60) with respect to the list of equipment requiring replacement displayed on the screen.

[0173] For example, if you click Run Product Recommendation on the list screen or equipment screen, a list of installable equipment will be displayed.

[0174] The priority for evaluation and recommendation can be set so that the algorithm is performed in the following order: product type - sorting of possible product types - comparing explosion-proof information (selecting and comparing variables for changed zone information items) - sorting of items requiring replacement (providing non-conformance messages) - sorting of conforming products.

[0175] When making recommendations by sorting suitable products, the algorithm can be performed in the following order: full search by product type, comparison of explosion-proof information, and sorting of suitable equipment.

[0176] This function automatically provides information on necessary equipment for n (multiple) pieces of equipment from an overall perspective of the area, rather than providing information based on existing equipment. It is a useful function that allows you to immediately check a list of other products that can be used (replaced) when conditions arise where existing equipment cannot be used due to changes in area information (environment).

[0177] As illustrated in FIG. 5, an explosion-proof management system according to one embodiment of the present invention includes a barrier that performs an automatic blocking function when an electrical hazard occurs, and may include an intrinsic safety management unit (300) that reviews a design that satisfies electrical parameter matching by considering the barrier cable explosion-proof device when at least one situation selected from among a barrier change, a cable replacement, and a field device change occurs.

[0178] Intrinsic safety is a system concept in which a barrier-cable-field device is connected to achieve explosion protection. Barrier changes, cable replacements, and field device changes can be performed individually. To this end, the intrinsic safety management department (300) determines whether an explosion-proof safety design has been achieved through comparison (matching) of intrinsic safety parameters.

[0179] The above-mentioned intrinsic safety management unit (300) can perform inspections to replace the field device while using the barrier and cable as they are, inspections to replace the barrier or cable while using the field device as they are, inspections to replace all of the barrier, cable, and field device, etc.

[0180] The intrinsic safety management unit (300) of the explosion-proof management system according to one embodiment of the present invention may be characterized in that it determines that a normal design has been achieved if all input-side and output-side requirements for voltage, current, power, capacitance, and inductance are satisfied based on the barrier for each circuit.

[0181] That is, the intrinsic safety management department (300) requires electrical parameter matching.

[0182] The important thing here is that the requirements for voltage must be satisfied, the requirements for current must be satisfied, the requirements for power must be satisfied, the requirements for capacitance must be satisfied, and the requirements for inductance must be satisfied to make a conformance decision.

[0183] In other words, if any one of the requirements is not met, a failure is determined.

[0184] Here, the electric source side with respect to the barrier is called the input side, and the field device side is called the output side.

[0185] The input and output side requirements of the explosion-proof management system according to one embodiment of the present invention are

[0186] Ui(input side voltage) ≥ Uo(output side voltage),

[0187] Ii(input side current) ≥ Io(output side current),

[0188] Pi(input power) ≥ Po(output power),

[0189] Ci(input capacitance) + Cable C(cable capacitance) ≤ Co(output capacitance),

[0190] Li(input inductance) + Cable L(cable inductance) ≤ Lo(output inductance)

[0191] It can be characterized by being.

[0192] That is, in a circuit that requires intrinsic safety suitability judgment, the input voltage must be greater than or equal to the output voltage with respect to the barrier, the input current must be greater than or equal to the output current with respect to the barrier, the input power must be greater than or equal to the output power with respect to the barrier, the sum of the input capacitance and the cable capacitance with respect to the barrier must be greater than or equal to the output capacitance, and the sum of the input inductance and the cable inductance with respect to the barrier must be greater than or equal to the output inductance.

[0193] The suitable equipment recommendation unit (100) of the explosion-proof management system according to one embodiment of the present invention may be characterized by verifying a certificate through a search of an authentication site for explosion-proof equipment information.

[0194] Certificate verification through a search on the certification site is intended to check for false records, errors in registration information, etc.

[0195] For example, if you are IECEx, once the certificate verification process is completed, you can access iecex.com, go to "view certificate & license", and enter your certificate number in the search box to perform a search.

[0196] If there are no search results, you can output "None".

[0197] If you search with the exact input, the corresponding certificate will be found, and you can perform a text comparison on the bottom right page.

[0198] If the authentication numbers match through text comparison, the one with the highest issue number is opened.

[0199] At this time, you can output that the authentication is invalid if it is not current.

[0200] When the certificate is opened, the 'Applicant' in the certificate can be compared with the manufacturer information entered by the supplier, the 'Equipment' in the certificate can be compared with the product name entered by the supplier, the 'Marking' in the certificate can be compared with the 'marking' in the registration information entered by the supplier, and the Marking in the certificate can be compared with the explosion-proof information entered by the supplier. If a match is found, a result of conformity can be output.

[0201] The above example describes a method of analyzing image information so that verification of a certificate is performed automatically, but the present invention is not limited thereto, and since information matching may not be smooth, a function may be provided that allows the purchaser (User) to directly verify the certificate.

[0202] The present invention is not limited to the above-described embodiments, and the scope of application is diverse, and various modifications can be made without departing from the gist of the present invention as claimed in the claims.
