The procedural steps for granting access if the condition in question is met are outlined in 20 It is characterized by its inclusion. In the operations carried out within the scope of the invention, only the measured disinfectant was used. Assessment of concentration or other physical parameters is sufficient. This is not observed. Because the sensors lose calibration over time, 25 changes in their performance due to contamination, aging, and chemical exposure or the same physical environment having different reliability levels as a result of being affected by different environmental conditions. It can be measured at these levels. Therefore, only technical measurement data is available. Its use can lead to misleading results in terms of operational safety. To eliminate this problem, the invention includes, in addition to the technical measurement data (T) Operational reliability data set (S) representing the sensor's operating history is being evaluated.

Thus, the same physical measurement value provides the sensor's true reliability of 15. Depending on the situation, it can be evaluated at different security levels. The invention also covers human exposure limits and re-entry concentrations. limits, biological activity criteria, concentration-time (CT) values, legal limits Reference 20, which may consist of security thresholds that can be defined by the user. A security dataset (P) is used. The P data size is provided to the user in real time. This does not refer to the collection of psychological data, but rather to human exposure, biological activity, and a predefined reference consisting of perceptual acceptability limits when necessary This refers to safety data. Technical measurement data (T) indicates sensor reliability. The parameter (Rₛ), measurement uncertainty (U), and reference confidence data set (P) together form 25 The actual security status of the operation is determined by evaluation.

They are evaluated together. Within this context, technical measurement data 30 physical operational status, operational reliability data set measurement system The reference security dataset represents the security objectives, while the security dataset represents the reliability. Thus, instead of making a decision based solely on the measured value, the reliability of the measurement and 12 security objectives are evaluated together with the actual situation of the operation. It is determined. Preferably, the system produces gas, vapor, aerosol and / or plasma during operation. quantity, enclosed space volume, air circulation flow rate, discharge flow rate, temperature, relative humidity, 5 parameters such as degradation coefficients, initial concentration, and elapsed time using the expected change in disinfectant concentration over time It can calculate using a mathematical process model. The calculated value is then used with the sensor. Sensor error and process deviation are determined by comparing the technical measurement data measured by the system. or unexpected operating conditions may be identified. 10 As a result of these evaluations, the system was classified as: normal operation, limited security. operation, verification operation, evacuation operation, security-protection operation It determines the most appropriate of the operational situations. The determined operation Depending on the situation, the gas, vapor, aerosol and / or plasma production power, operation 15 duration, air circulation speed, exhaust fan flow rate, catalytic decomposition process, waiting time The duration and / or security of access to the enclosed area can be adaptively changed. Thanks to this invention, existing systems that make decisions based solely on sensor measurements will be able to move away from them. In contrast, sensor reliability, measurement uncertainty, reference safety criteria, and process 20 behavior is evaluated together; thus both human safety and Unnecessary waiting times and incorrect safety decisions while increasing disinfection effectiveness. And faulty operational management is significantly reduced. These units are software sub-units within the central operations control unit (1) 25 They can be implemented as modules, or as independent electronic control boards. industrial computers, PLC systems, embedded controllers, FPGA-based hardware, distributed control systems, or any combination thereof It can also be done in this way. The invention's operating principle is based solely on physical measurement values ​​in an enclosed space. not only the evaluation, but also the continuous analysis of the reliability of these measurements. This is based on preventing sensor aging, contamination, and calibration issues. 13 faulty decisions resulting from shifts or changes in working conditions The aim is to prevent this.

Instead, the operational history of the sensor that performed the measurement is recorded. It is constantly being evaluated. For this purpose, the operational reliability data unit (4) is the calibration of the relevant sensor. records, maintenance history, usage time, total operating hours, disinfectant exposure history, sensor drift logs, fault logs, alarm history, malfunction statistics and other operational information that could affect sensor reliability It collects and creates an operational reliability data set (S) from these. 20 Operational reliability data set (S), sensor reliability calculation unit (6) is transferred. Sensor reliability calculation unit (6), operational reliability data using the sensor set to represent the reliability level of the sensor measurement. It calculates the reliability parameter (Rₛ). 25 The sensor reliability parameter (Rₛ) can be a single coefficient or multiple coefficients. A composite reliability is formed by evaluating the reliability component together. It can also be calculated as an indicator. The calculation process uses weighted averages and statistical methods.

The margin unit (7) is transferred. This unit is used for technical measurement depending on the sensor reliability. It calculates the measurement uncertainty (U), which represents the confidence interval of the data. As sensor reliability decreases, measurement uncertainty can be increased. As the value increases, the measurement uncertainty can be reduced. Thus, the same measurement value can be used with 5 different types of measurements. They can be subjected to different security assessments at varying levels of reliability. Measurement uncertainty, along with an additional dynamic safety margin when needed. It can be calculated. Dynamic safety margin; sensor reliability, process variability, the criticality of the operation, the risk of human exposure and the disinfectant degradation behavior 10 an additional safety factor that can be modified taking into account the parameters is doing.

Cross-validation unit (9) is the expected value obtained from the mathematical process model. Real measurement obtained from the concentration and technical measurement sensor group (3) It compares the values. As a result of the comparison, sensor malfunction and calibration issues are identified. slippage, process deviation, gas leak, unexpected ventilation or other Operational anomalies can be detected. All information obtained is evaluated by the Psycho-Socio-Technical situation space assessment unit (10) It is analyzed jointly by 5. During this evaluation, technical measurement data is used. (T), operational reliability data set (S), reference safety data set (P), sensor By considering the relationships between the reliability parameter (Rₛ) and the measurement uncertainty (U) The current operational status of the system is determined. Depending on the determined operational location, the operational classification unit (11), 10 The system operates in normal operating mode, verification mode, and restricted secure operating mode. It switches the device to the appropriate mode, either evacuation mode or safety / protection mode. Central operation control unit (1), sensor reliability parameter (Rₛ) and measurement Taking into account the uncertainty (U), a different disinfectant concentration than the nominal concentration is used. Safety can calculate the corrected disinfectant concentration. Safety Corrected disinfectant concentration, operational control decisions is the basic concentration value used in its creation, and is only for the sensor. not only the nominal value measured, but also the reliability of the measurement. It includes. 20 Depending on the determined operational status, through the physical control output unit (12) gas and / or plasma production power, dosage amount, production time, air circulation speed, exhaust fan flow rate, catalytic decomposition system, retention time and / or other Operation parameters can be changed automatically. 25 Air circulation and exhaust control unit (13), disinfectant in the environment to optimize distribution, accelerate degradation, or ensure re-entry security to provide fans, dampers, HVAC components and air guidance They are able to control their systems. 30 Electromechanical access security unit (14), indoor doors, lock systems, It controls at least one of the turnstiles and access control systems. The system is for security. 16 corrected disinfectant concentration below the reference re-entry limit It does not allow access without falling, and when the necessary safety conditions are met... It can automatically release access. Data recording and learning unit (15), technical measurement obtained during the operation 5 data (T), operational reliability datasets (S), sensor reliability parameters (Rₛ), measurement uncertainties (U), operational decisions, mathematical It records model results and physical control procedures. This recorded information... in calculating the sensor reliability parameter in subsequent operations 10 for the purpose of updating at least one calculation parameter used. It is available and the system can improve its performance over time. The operational reliability data set (S) includes various aspects of the sensor's operational history. This dataset includes information such as the sensor's calibration date and calibration deviation. maintenance history, usage time, total operating time, total duty cycle, sensor 15 drift amount, chemical exposure time, alarm history, fault records, fault frequency, ambient temperature and humidity history, user intervention logs, sensor type, sensor aging coefficient, reliability information provided by the manufacturer and the sensor It may include at least one of the other operational parameters that could affect its reliability. Using the operational reliability data set (S), the sensor measurement was performed on 20 sensor reliability parameter (Rₛ) representing the reliability level is being calculated. In an application, the sensor reliability parameter Rₛ can be expressed as f(S). Here, S represents the operational reliability dataset. In a preferred application, 25 Rₛ is the normalization of calibration validity, sensor drift amount, and total runtime. It is a reliability coefficient between 0 and 1, formed from the selected components; 1 to 1 Values ​​close to 0 indicate high measurement reliability, while values ​​close to 0 indicate low measurement reliability. The calculation involves combining the components in question with predetermined weights. This can be done. Alternative applications include statistical, probabilistic, or data-based approaches. Calculation methods can be used. 17 Within the scope of this invention, the measurement uncertainty (U) is determined solely by the sensor manufacturer. It depends on the sensor's current reliability status, not on a defined fixed error value. It is defined as a dynamic security dimension. In a preferred application As Rₛ decreases, U is increased; as Rₛ increases, U is decreased. Thus, U becomes nominal. The measurement uncertainty used to assess the sensor value on the safe side is 5. It represents its share. One of the key technical features of the invention is the nominal disinfectant obtained from the sensor. The sensor's concentration is not directly used in operational decisions. The nominal disinfectant concentration, measured by the central unit, is expressed as Cₙ. The operation control unit assesses safety by evaluating Cₙ and the measurement uncertainty (U) together. It establishes the corrected disinfectant concentration (Cₛ). Preferred re-entry. In safety applications, the relationship Cₛ = Cₙ + U is used. Thus, measurement reliability is ensured. As U increases when it decreases, it cautiously raises the safety-corrected concentration and Different access levels for the same nominal measurement value at different sensor reliability levels. 15 This allows them to make decisions. Within the scope of the invention, the central operations control unit manages the disinfection operation. It also evaluates physical behavior using at least one physical process model. Preference In a given application, the expected disinfectant concentration in an enclosed space is 20 Cₘ. The relation dCₘ / dt = Pᵍ - k·Cₘ - (Q / V)·Cₘ, based on mass balance, is used. Here, Pᵍ is brrrm Disinfectant production or injection terminology released into the environment over time, degradation where Q represents the air circulation or exhaust flow rate and V represents the enclosed space volume. In alternative applications, exponential decay represents the same physical process. reaction kinetics, multi-zone air circulation, CFD, empirical or data-driven models 25 available. Within the scope of the invention, either only the results of the mathematical model or only the sensor Instead of basing the assessment on individual measurements, both sources of information are evaluated together. For this purpose, the cross-validation unit uses 30 sensors obtained from the technical measurement sensor group. by mathematical process model with nominal disinfectant concentration the calculated expected disinfectant concentration continuously 18 It compares two values. In an application, the difference between two values ​​is expressed as Δ = |Cₙ − Cₘ|. It can be calculated. The calculated difference must exceed predetermined threshold values. In this case, sensor calibration drift, sensor failure, gas leak, unexpected events ventilation, process deviation, equipment failure or other operational issues At least one of the anomalies can be detected. Cross-validation results in 5. The information obtained is used in updating the sensor reliability parameter, measurement. in recalculating uncertainty and validating operational decisions It is available for use. One of the key innovations of the invention is that the operational decision is based solely on physical measurement. not based on their values, but on technical measurement data (T), operational reliability data set (S) and by jointly evaluating the technical relationship between the reference security data set (P) It is the creation of a physical operating state (T) and a measurement state (S) in the PST state space. It represents the current reliability of the system and the P security objectives. It is formed from S. Rₛ modifies the measurement uncertainty U; U is the safety-corrected nominal concentration Cₙ 15. Concentration is used to convert Cₛ; Cₛ is then reconstituted within P. By comparing it to the entry limit, it is converted into a physical control and access decision. Thus The state space provides physical reliability for measurement instead of generating an abstract score. It functions as a relational technical control structure that represents its influence on the decision. As a result of the evaluation performed in the PST state space, the current state of the system... Operation status is determined. Operation status: normal operation, verification. operation, restricted security operation, evacuation operation or security-protection It is classified as one of the operations.
