The mechanisms allow for the remote and safe monitoring of gas concentrations in tanks. It relates to a measurement technology that enables monitoring. The invention also includes a control algorithm for data obtained from gas measurement processes. processing through, designating certain ports as critical ports by the operator the ability to define these ports and dynamically prioritize them in the measurement cycle, Sampling times can be adjusted according to conditions, and the system architecture is modular. Designed in a way that allows it to be adapted to facilities of different scales, advanced automation 25 It also encompasses its functions. In these respects, the invention is not only a device that takes gas samples. not only the structure, but also the automation, monitoring and risk management functions are integrated. It is an industrial gas monitoring platform. State of the Art 30 In the interior environments of tanks found on ships, shipyards, and industrial facilities. the accumulation of flammable, explosive or harmful gases and the release of these gases over time The fact that it is present at varying levels is a significant security problem. Existing In applications, monitoring the gases in these tanks is mostly done using portable gas measuring devices. 35 2 This is done through devices. Operators have physical access to the tanks and sample the product. They need to submerge their hoses or take measurements in the vicinity of the tanks, This situation leads to both operational delays and risky conditions in terms of workplace safety. This is the reason. Furthermore, in measurements made using manual methods, factors such as time and sampling method are also important. Since tank sorting and registration procedures depend on operator initiative, it is incorrect (5). There is a high probability that readings or measurements will be inaccurate. A significant portion of known systems involve sequential measurements from tanks using a single device. It is based on speed and efficiency in environments with numerous tanks. It is insufficient. Line 10 is used during the transportation of gas samples coming from long lines. Since it involves the transport of gas remnants from previous ports, it is different. the measurement results of the tanks can influence each other and cross-contamination can occur. It is possible. A purge process is necessary to prevent this situation, but currently... In applications, the purging process is usually manual, non-standard, and depends on operator experience. This is done in a connected manner. The determination of the purge duration is often approximate and line 15 parameters such as length, hose diameter and vacuum level are automatically taken into account Failure to take action limits the effectiveness of the purge. The referenced application CN214504198U in the literature refers to a negative multiple valve structure. a pressurized aspiration line and a control structure that manages this line sequentially is described 20 The technical problem with this system is that sequential samples are taken from different points, and It is the management of negative pressure using a valve system. However, in this structure, it is automatic. There are no dilution ports or purge ports; high concentrations of gases... The dilution architecture that prevents damage to the sensors is not defined, port It is not possible to change the ranking according to the risk level, and critical port 25 Advanced control such as dynamically changing the identification or measurement frequency. Its functions are not included. Furthermore, the gas measurement unit and battery-powered manometer readings are not included. There is also no camera-based mechanism for simultaneous verification. Similarly, reference CN111766326B provides gas-phase samples 30 from reactor environments. It offers a parallel negative pressure system aimed at capturing the gas from the sample. on maintaining stability in the phase and performing reliable analysis in the reaction medium It is becoming more concentrated. However, this structure allows a large number of tanks to operate from a single platform. management, automatic execution of dilution and purge functions, risk-based port prioritization algorithm, standard purge cycle on long lines, modular valve 35 3 industrial systems such as box architecture and an infrastructure that can be expanded via a control box. It does not meet monitoring requirements. In current systems, the sensors of gas measuring devices detect high concentrations. To prevent it from being affected by gases, the dilution process is either not present at all or 5 It is also limited and applied manually. Gas levels exceeding the measurement range. This can lead to calibration drift in the sensors, false alarms, or sensor failure. It can open. Therefore, in samples taken from high concentration tanks The lack of a reliable automatic dilution mechanism is a significant problem in known techniques. It creates a gap. 10 Most known systems do not work in an integrated manner with automation, Prioritizing ports based on their criticality, analyzing historical measurement data. by measuring high-risk ports more frequently and extending the measurement interval of low-risk ports. Intelligent control such as extending and dynamically optimizing measurement cycles 15 They lack mechanisms. In such systems, the measurement sequence is mostly static. Adaptation to changing tank behavior is not possible. In addition, in known techniques, negative values ​​correspond to the values ​​obtained from the gas measurement unit. Simultaneous 20 with battery-powered manometer for independent verification of the pressure line with a reference. There is no camera mechanism that allows taking screenshots. This Therefore, it is possible to visually verify the measurements during port changes. This is not the case, and remote detection of pressure-measurement discrepancies becomes difficult. In non-modular, non-expandable systems, new tanks, valve boxes, or 25 Integrating control units into the existing structure is difficult and costly. In distributed environments... Centralized management of the located tanks via a single negative pressure line, Calculating automatic sampling times based on line lengths, port sequencing. such as readjusting according to the criticality level determined by the operator. These functions are not common in the literature. 30 For all these reasons, the current technology offers advantages in terms of safety, automation, measurement accuracy, and It has significant shortcomings in terms of scalability. It is very weak under negative pressure. Gas sampling, automatic dilution and purge mechanisms in a ported structure, critical port Risk-based dynamic sampling function, battery-powered pressure gauge – gas measurement unit verification 35 4 an integrated gas system that combines a modular, expandable architecture. Monitoring systems are not found in the literature. Purpose of the Invention The primary purpose of the invention is to replace the many types of materials found on ships in shipyards and in industrial facilities. taking gas samples from a number of tanks, and safely storing these samples under negative pressure transport in this manner, dilution of measurement processes and critical port cycles standardization and automatic classification of the obtained gas data according to risk levels. It offers an integrated multi-port gas monitoring and control system that enables its processing. The invention reduces delays, potential errors, and limitations caused by manual measurement methods. It aims to eliminate risks related to operator safety. Another objective of the invention is an automatic dilution port, which is not available in current systems. This prevents high concentrations of gases from damaging the sensors during measurement. reducing values ​​exceeding the range to sensor safety levels and system components The goal is to ensure that it always operates within a safe zone. Similarly, the invention; in the valve box thanks to the purge ports located there, in long lines or facilities with multi-point structures In-line residual gases are automatically controlled as determined by the control algorithm. By ensuring standardized cleaning, the problem of cross-contamination is eliminated. It aims to eliminate it. Another objective of the invention is to dynamically adjust the measurement time and measurement frequency for each port. The key is to provide the critical port (CP) function, which makes it possible to adjust this. in this way, areas identified by the operator as critical or having a high risk level The ports detected by the system are measured more frequently, and low-risk ports are identified more often. This ensures that it is checked infrequently; thus, both the overall efficiency of the system increases and Gas accumulation trends in risky areas are detected earlier. The invention also involves the values ​​obtained by the gas measuring unit in the negative pressure line. so that it can be verified along with the pressure levels, located inside the control box Port changes between the gas measurement unit display and the battery-powered manometer display with the aid of a camera. It aims to display the measurements simultaneously. This structure allows for the simultaneous visualization of the data. This facilitates visual verification and remote control of pressure-measurement consistency. This makes it possible to track it. Another aim of the invention is to enable ships to be equipped with modular valve boxes and a distributed layout structure. a single system of tanks distributed across different areas along or throughout an industrial facility The aim is to enable management through a central control system. This modular architecture; the system allows for the easy addition of new tanks, new valve boxes or side boxes, Optimizing sampling times based on variations in line lengths and This makes it possible to expand the system to suit field conditions. Finally, one of the aims of the invention is to integrate the control unit, valve boxes, gas measuring unit, and vacuum. the infrastructure created between the sources is compatible with industrial communication protocols, It is expandable and suitable for future integration into PLC-based systems. It is the design. The invention is designed to fulfill the above purposes in ships, shipyards and industrial facilities.

It is related to the analysis system. The system is controlled by a central control box (1) that operates within it. Taking gas samples from tanks through the algorithm (15), these samples are Safe Moving to the gas measurement unit (8) located in the safe zone defined as Area, Automatic application of dilution and purge processes, port sequencing and measurement 15 dynamic management of the cycles and, when necessary, the ventilation fans (11) enables commissioning. Thanks to this integrated structure, in hazardous areas Manual measurement systems requiring operators are largely eliminated, and gas The monitoring process can be managed entirely from a secure area. The system uses negative pressure lines instead of positive pressure lines to collect gas samples from the tanks. It is based on the principle of transport. Negative pressure, vacuum located in the Safe Area. It is created by the source (9). Hoses for tanks, tank connection ports (4) They are connected to valve boxes (3) and samples are transported through these valve boxes (3). 7 The negative pressure line (10) is drawn towards the gas measuring unit (8). Thus Gas transport between the hazardous zone and the safe zone is controlled by a system created along the pipeline. This is achieved through a negative pressure difference. The Safe Area architecture forms the basis of the security approach in the invention. System 5 In its design, it is essential that no electrical equipment is present in the hazardous area. This Therefore, control box (1), side boxes (2), gas measuring unit (8), vacuum source (9), camera (12) and other electronic components in Safe Area or semi-safe areas It is located in the hazardous area. Only passive hose lines and gas-carrying pipes are present. There are connecting elements. This allows for the creation of a spark or ignition. 10 Ensuring that electrical components that could pose a risk are not located in the hazardous area. is being received. The system also features a Safe Area verification approach. By design; valve boxes (3) and there is no electrical supply line in the field lines, only 15 with hose connections, field installation and commissioning procedures. It is confirmed. The circuit is made via the control box (1) and side boxes (2). In the tests, only signal and power lines were allowed into the field up to the Safe Area boundary. where it was taken, and on the tank side there was a network of hoses that did not carry electrical charge. This architecture systematically controls the use of electrical equipment in the hazardous area. It provides a security layer that prevents this. The system consists of: control box (1), side boxes (2), modular valve boxes (3), tank connection ports. (4), dilution port (5), purge ports (6), solenoid valves (7), gas measuring unit (8), vacuum source (9), negative pressure line (10), ventilation fans (11), camera (12), data 25 line (13), power line (14), control algorithm (15), water sensor (16) and battery-powered manometer (17) It has an integrated architecture consisting of a single gas metering infrastructure. enabling the monitoring of numerous tanks, line integrity, and pressure status. ensuring that it is kept under constant control and that the reliability of the measurement is maintained. It creates a modular and expandable gas monitoring platform. 30 The control box (1) acts as the central control and decision-making unit of the system. The control algorithm (15) that runs inside the control box (1); all ports are working order, port open times, dilution cycles, purge operations, negative monitoring pressure levels, critical port (CP) management, and vacuum testing functions. 35 8 It carries out the control algorithm (15) also the measurement taken from the gas measuring unit (8). In analyzing the results, ventilation fans (11) are used when the threshold values ​​are exceeded. It enables automatic activation and ensures the system is secure when necessary. They decide to implement the fashion trend. The operator defines the system configuration on the control box (1) There is a user interface that provides access to tanks and ports. Through this interface, mappings, port definitions, critical port assignments, dilution and purge parameters, Alarm threshold values, vacuum test periods, and test mode settings are entered. These parameters are read by the control algorithm (15) and the system's operation 10 Its logic is dynamically shaped according to these parameters. Thus, the invention is both having both automated decision-making mechanisms and operator-defined settings. It can be flexibly adapted to operating conditions. Data communication between the control box (1) and the side boxes (2) located in the field, data 15 It is provided via CAT6 type Ethernet cables configured as line (13). This line contains port opening / closing commands, real-time port status information, and sensor data. data, dilution and purge commands, critical port statuses, alarm notifications, and negative Pressure levels are transmitted bi-directionally. The system components receive power supply. the power line (14) is supplied and the valve 20 is connected to the side boxes (2) via this line. The energy required by the boxes (3) is distributed in a controlled manner. Side boxes (2) provide regional distribution and signal between the control box (1) and the valve boxes (3). It functions as a data transfer center. Side boxes (2), control box (1) and CAT6 data They communicate via line (13), and 16-core signal cables are connected to the valve boxes (3) 25 It transmits port commands through these 16-core cables in field conditions. For example, it can extend up to 80 meters, thus allowing for use on large ship decks or Reliable signal transmission to distributed valve boxes in large industrial facilities. Side boxes (2) can also provide power supply to the valve boxes. It provides via line (14). 30 All side boxes (2) of the system communicate with each other via CAT6 cables. This communication topology is particularly common in long shipping lanes and large facilities. dividing cable distances into manageable segments, maintenance and fault detection processes It simplifies the process and makes it easier to add new valve boxes to the system. Modular 35 9 Thanks to the architecture, when new tanks are added to a site, they are positioned close to these tanks. It is sufficient to simply add a new valve box (3) and, if necessary, a new side box (2). This happens when these new units are connected to the system’s CAT6 data line (13). is recognized by the algorithm (15) or by the operator user interface It can be manually registered in the system. This structure allows the invention to be scalable. 5 and enables it to function as a future-oriented gas monitoring platform. The control box (1) also provides higher-level monitoring via modem or network interface. It is designed to be able to connect to software or a cloud-based data server. This allows you to see port measurement results, critical port activities, vacuum test reports, and alarm 10. The recordings can be monitored remotely. Within the scope of the invention, via the control box (1) Manual port opening and closing commands via the provided web-based interface, Purge initiation commands, critical port assignments, and triggering of test mode are among the processes involved. It can also be done remotely. Thus, the system can be controlled not only from the local panel, but also from a remote location. It also has an architecture that can be managed via remote access. 15 Valve boxes (3) are where samples from tanks enter the system and connect to the tanks. Modular field units containing ports (4), dilution port (5) and purge ports (6) It operates as follows. Each valve box (3) has multiple tank connection ports (4) These ports receive polyurethane / polyethylene 20 from the internal environment of the relevant tanks. Hoses are connected. These hoses are reliably connected along the negative pressure line (10). It forms a gas flow path. Within the scope of the invention, the port structure of the valve boxes (3) is configurable. Each In the valve box (3) tank connection port (4), dilution port (5) and purge port (6) 25 The number of valves can be adjusted according to the operation. In an example application, each valve... In its box (3) there are 12 tank connection ports (4), 1 dilution port (5) and 2 purge ports. (6) ports can be found. This port distribution depends on the number of tanks in the field, line lengths and It offers a flexible architecture that can be modified according to operational requirements. The dilution port (5) is on the gas measuring unit (8) for high concentration gases. to prevent the sensors from exceeding their operating range and to ensure the main line is always considered "safe". negative pressure to ensure that an explosive gas is kept below a certain limit It mixes a controlled amount of clean air or inert gas into the flow in line (10). The control algorithm (15) activates the dilution port (5) only when needed. It operates on the principle of dilution mode. In this mode, the gas coming from the tank... expected concentration, historical measurement profile, critical port status, and sensor operation. The range is evaluated together and dilution ratios are dynamically adjusted, for example, 1:6. It can be adjusted between 1:30. This allows both the sensors to reach saturation and... Calibration drift is prevented, and system components always remain safe. It is ensured that it remains within the working range. Purge ports (6) remain within the negative pressure line (10) between port changes. It is used for cleaning gas samples. Thanks to its purge mechanism, a The gas from the previous measurement affecting the new measurement result when switching from one port to another. 10 This prevents and eliminates the risk of cross-contamination. Purge The function is controlled conditionally and dynamically by the control algorithm (15). It is managed. The gas level is low, the hose length is short, or The purge function is activated when there is no risk level in the previous port. It is not mandatory to remove them. However, tanks containing high concentrations of gas are suitable for a long period of 15 days. When dealing with hose lines or critical ports, check the purge ports (6). The algorithm (15) is automatically activated and the purge time; hose such as length, negative pressure value, gas type, and measurement results from the previous port. The parameters are optimized taking them into consideration. This approach is manual purge. More stable compared to traditional methods where durations depend on operator experience. 20 and produces reliable results. All ports in the valve boxes (3) have solenoids responsible for opening and closing the respective lines. They are equipped with solenoid valves (7). The solenoid valves (7) respond to commands from the side boxes (2). opening or closing and tank connection ports (4), dilution port (5) and purge 25 It ensures that the ports (6) are activated in the desired order and for the desired duration. The control algorithm (15) can define independent time profiles for each port and Based on these profiles, it can dynamically change the order in which the ports operate. Negative pressure line (10); all gas taken through tank connection ports (4) 30 It refers to the main flow line through which the samples are transported to the gas measurement unit (8). This line starts from the valve boxes (3) and goes to the gas metering unit (8) located in the Safe Area. extending up to and under continuous negative pressure by the vacuum source (9) Polyurethane / polyethylene hoses used in the negative pressure line (10), 35 that will provide low gas permeability, high flexibility and stable flow over long distances. 11 They are selected in this way. In example applications, hoses with dimensions of 8×5.5 mm are used. Lines reaching 300–700 meters in length are used on ship decks or industrial sites. Reliable gas transportation can be ensured even over long distances. The vacuum source (9) produces the required vacuum level on the negative pressure line (10) 5 It is a pump or vacuum production unit. Vacuum source (9), in Safe Area It is positioned and powered via the power line (14). The vacuum level, Control algorithm (15) depending on the operating conditions and line lengths of the system It is monitored and adjusted as needed. The negative pressure level is determined by a specific system. If it falls below a limit, the control algorithm (15) measures the cycles 10 It can stop, prevent new ports from opening, and vacuum the operator. It can generate a warning regarding the level. This allows for potential breakages in the hoses. Pinching or loosening of connections is detected at an early stage. The system has flow and vacuum levels that vary according to the physical characteristics of each port. It has a dynamic operating logic that takes into account its behavior. Each tank connection hose length for port (4), hose inner diameter, filter type used and hose to tank Its position within the sample (upper, middle, or lower level) can vary; these differences affect the sample's It affects the time it takes for the gas to reach the measuring unit (8) along the negative pressure line (10). Within the scope of the invention, the control algorithm (15) is based on these parameters for each port 20 dynamic port duration function that automatically adjusts the measurement time on a port basis has. The dynamic port time function calculates the inline filling time of the sample from each port. Analysis of vacuum behavior and stable measurement time read by gas measurement unit (8) 25 This analysis determines the optimal measurement time for the relevant port. The time control algorithm (15) is stored in memory. Progressive measurement When the same port is activated in the cycles, the control algorithm (15) controls this dynamic time By applying it automatically, it both shortens the cycle time and eliminates the need for measurement. First, it ensures that the line is adequately filled. Thus, the long hose 30 unnecessarily short waiting times at ports, and unnecessarily long waiting times at ports with short hoses. By preventing this, a significant increase in efficiency is achieved across the system. The invention also includes a port calibration function. Port calibration The function is to provide an independent reference vacuum pressure profile for each tank connection port (4) 35 12 the creation of this profile and its recall during normal operation, enabling port changes. It allows for automatic implementation. Control algorithm in the calibration process. (15) pressure in the negative pressure line (10) during commissioning of certain ports examining its changes, the level and time interval at which the system becomes stable It saves it as a reference value. 5 During this process, manual testing was performed on the negative pressure line (10) with a battery-powered manometer (17). Measurements are taken with pressure or vacuum data read by the gas measuring unit (8). They are compared; thus, a reference based on both manual and automatic measurements is created. A vacuum profile is created. This reference profile is then used separately for each port (10). is stored in memory and the control algorithm (15) is within the scope of the port calibration function. It is used by. When a port is activated during normal operation, the reference vacuum for that port is determined. The profile is automatically called and the instantaneous vacuum behavior in the negative pressure line (10) 15 This is compared with the reference profile. If the port's vacuum behavior differs significantly from the reference profile... If it deviates to a certain extent, the control algorithm (15) marks the relevant port in red on the operation panel. It signals and simultaneously produces an audible warning. This situation occurs in the relevant hose. leakage, blockage, partial deformation, or behavior inconsistent with the tank level This indicates that maintenance crews can proceed before even entering the tank or within 20 minutes. It can detect potential malfunctions before the operation is seriously affected. The port calibration function and the dynamic port duration function work together to calibrate each port. an adaptive control system in terms of both time optimization and vacuum behavior. This allows the system to accommodate a wide variety of hose lengths and field conditions. However, it is able to produce stable and repeatable measurement results for each port. Within the scope of the invention, the leak tightness of the negative pressure line (10) and connected components A vacuum test function has been defined for verification purposes. The vacuum test examines the system. before commissioning, during periodic maintenance work, or in case of suspected vacuum 30 It is an integrity control mode that can be used in situations where behavior is being observed. During the vacuum test, the control algorithm (15) checked all tank connection ports (4), dilution port (5) and purge ports (6) are closed via solenoid valves (7). It brings. Then the vacuum source (9) is activated and the negative pressure line (10) 35 13 It is drawn to a predefined reference vacuum level. To this level When reached, the vacuum source (9) is operated in constant mode for a certain period of time or tested According to the scenario, it is being decommissioned; in both cases, the negative pressure line (10) The pressure change is monitored over time by the control algorithm (15). If the line is perfectly sealed, the vacuum level will be within the specified tolerance range. It remains constant or changes very slowly. In contrast, at hose connections, the valve leakage in boxes (3) or fittings, hose breakage or connection If relaxation occurs, the vacuum level drops faster than expected. is falling. The control algorithm (15) is the reference value at the beginning of the vacuum test and 10 It records the target time; and during the test period, it analyzes the pressure curve to determine the tolerance. It flags any deviations outside of this range as errors. A statistical or graphical profile is created as a result of the vacuum test, and this profile It can be reported to the operator via the control panel. Critical leak detection level 15 When this is done, the control algorithm (15) disables the relevant line or module, stopping the measurement cycles or only using the ports that have been confirmed to be safe. It can automatically make decisions that will enable its use. This function, especially ships and large vessels with long-distance and complex hose networks It operates as a fundamental security feature in facilities, maintaining system integrity. 20 The vacuum test function works in conjunction with the port calibration function; on the one hand, each It profiles the normal vacuum behavior for the port, while also showing the behavior across the entire line. It periodically verifies the integrity level. Thus, the system verifies both the local port integrity level. Two-layered vacuum monitoring and leak control, both at the base level and across the entire line. 25 It offers. Gas measurement unit (8) measures the gas samples coming through the negative pressure line (10). It is a device that measures the components and concentrations of gases. It can include multiple gas sensors. This unit is responsible for monitoring the limit values ​​of flammable, explosive, toxic and asphyxiating gases. 30 It allows for the gas measurement unit (8) to be located in the Safe Area and controlled. It communicates with the box (1) via the data line (13). Measurement results are instantaneous. The system's security is transmitted to the control algorithm (15); if the alarm thresholds are exceeded, the system's security The functions are activated automatically. 35 14 The battery-powered manometer (17) measures the pressure level above the negative pressure line (10) from the system. pressure measurement that allows verification with an independent, portable reference device. It is a self-powered unit. Because it operates with its own energy source, it is independent of the electrical status of the system. It can take measurements in this way. The operator checks the battery-powered manometer (17) on the line at certain intervals. By connecting it to the appropriate point, the vacuum or pressure indicated by the gas measuring unit (8) is 5 It is possible to manually check the values. This verification process is port calibration. also in the creation of reference pressure profiles within the scope of its function It is used. The camera (12), located inside or near the control box (1), measures gas 10 Simultaneous display of the unit (8) screen and the battery manometer (17) screen It can be configured to provide the control algorithm (15), port changes. or can generate trigger commands for the camera (12) during specific test scenarios; Thus, both the gas measurement results and the negative pressure value are recorded simultaneously. This ensures that the numerical records on the screen are kept under control. Thanks to this structure, the operator can see 15 of the numerical records on the screen. In addition, they can access real-time images from the measuring devices and back Photographic or video recordings may be used when a detailed investigation is required. In another application form of the invention, the control box (1), modem or network interface It is equipped with a communication module containing port measurement results. Through this module, 20 critical port activities, vacuum test reports, calibration alerts, and camera footage. It can be transmitted to a remote monitoring center or server. A web-based interface. Authorized users accessing the system via the portal can view measurement data in real time. They can monitor, review past records, and remotely adjust system parameters. can make changes. 25 In this context, manually opening a port via the web interface, purge initiating the cycle, assigning the critical port (CP), triggering the test gas mode, and It is possible to temporarily disable specific ports if needed. This is possible. Remote access, especially in unmanned or hard-to-reach areas, is possible from the ship 30 when at sea or in certain parts of the facility where physical access is restricted In these situations, it provides significant operational advantages. In another application form of the invention, the system is a multi-point gas measurement unit (8). It has a test gas mode that offers functional testing capabilities. Within this mode, the Safe 35 A negative result is obtained via a test tube or calibration gas cartridge located in the area. A controlled amount of test gas is supplied to the pressure line (10). The control algorithm (15), As soon as the test gas is introduced, the relevant ports are activated in a specific sequence and the gas measurement unit (8) records the values ​​read by the system. Thus, all ports of the system and The gas metering infrastructure functions under a scenario similar to real operating conditions. This is confirmed. This test mode detects sensor failures and out-of-calibration behavior. It is an important maintenance function aimed at detecting blockages or obstructions within the lines. The invention relates to risk-based measurement in environments where multiple tanks need to be monitored simultaneously. It has a critical port management function that enables the implementation of the strategy. Critical 10 port; facility security protocols, type of gas contained in the tank, historical measurement data or tank connection ports which need to be monitored more frequently depending on operational conditions (4) This is stated. The operator uses the user interface located in the control box (1) to express this. It is possible to designate specific ports as critical ports (CP), or this designation can be used for specific alarms. Automatic control algorithm (15) for ports with history 15 It is possible. Within the scope of critical port management, the control algorithm (15) normal port measurement cycle It defines additional measurement ranges for critical ports without disrupting them. For example; all ports While measured sequentially from 1 to 84, port number 10, marked as the critical port, has a range of 5–20. An additional measurement can be triggered every minute. In this case, the system switches to a normal cycle. It maintains the flow (1,2,3…84); however, with the addition of sub-loops, the critical port (10) is further protected. It is put into operation frequently. In this way, samples are taken from high-risk tanks at shorter intervals. Measurements are being taken, and the frequency of measurements of low-risk tanks will ensure efficient use of system capacity. It is kept in balance in this way. 25 The control algorithm (15) measures the frequency of critical ports; the number of past alarms of the port, Temporal variation of measured gas concentration, operational priority and field It can adjust dynamically based on parameters such as the security regime. Critical 30 when the risk level at the port decreases or when no alarm is generated for a certain period of time. The system can automatically return the relevant port to its normal loop speed. This Thanks to its dynamic structure, both the early warning mechanism is strengthened and the system Overall, unnecessary congestion and waste of resources are prevented. 16 The modular architecture of the invention allows new tanks to be added or the existing tank structure to be modified. In various situations, the system is designed to be easily expanded. When new tanks are added to the field, only a new valve can be placed in a location close to these tanks. It is sufficient to add a valve box (3) and, if necessary, a new side box (2). New valve boxes (3) connects to the CAT6 data line (13) via side boxes (2); control algorithm 5 (15) makes these units integrable into the system by addressing them. The operator, By defining new boxes and ports to the system from the interface (1) in the control box, measurement It can adapt its cycle to the new configuration. The modular design also offers significant advantages in terms of fault management. Each valve box contains 10 (3) Since it can be considered as an independent module, it can be used in any valve box or When a fault is detected on that line, other parts of the system continue to operate. It is possible to do so. Maintenance procedures are carried out by deactivating the faulty module, and this During this process, the monitoring of other tanks can continue uninterrupted. Thus... The invention features automation, security, dynamic analysis, risk management, and modular scalability. 15 It offers an advanced gas monitoring solution that combines its functions on a single platform.
