Description

Technical Field

[0001] The present invention relates to the field of hazardous chemical supervision and safety technology, and in particular to a hazardous chemical supervision system and a supervision method thereof. Background Art

[0002] With the acceleration of industrialization and urbanization, the safety management of hazardous chemicals during their production, storage, transportation, and use has become increasingly prominent. Due to their inherent flammability, explosiveness, toxicity, and harmful properties, hazardous chemicals pose a serious threat to human life and safety in the event of a leak, fire, or explosion. They can also cause irreversible environmental pollution, impacting social stability and economic development. Therefore, strengthening the supervision of hazardous chemicals and enabling real-time monitoring and early warning of their status have become crucial issues for safeguarding public safety and preventing chemical accidents. However, traditional methods of hazardous chemical supervision rely heavily on manual inspections and periodic checks, which present challenges such as untimely information acquisition, incomplete monitoring, and delayed early warning. Furthermore, the wide variety of hazardous chemicals, each with its own unique storage conditions, chemical properties, and safety requirements, increases the complexity and difficulty of supervision. Summary of the Invention

[0003] In view of this, the present invention addresses the deficiencies of the prior art and proposes a hazardous chemicals supervision system and supervision method thereof, aiming to solve at least one of the problems raised in the above background technology.

[0004] In a first aspect, the present invention provides a hazardous chemical supervision system, comprising: a collection module, the collection module being configured to collect status information of target hazardous chemicals in real time;

[0005] A transmission module, configured to transmit the collected status information;

[0006] a storage module, the storage module being configured to receive the status information transmitted by the transmission module and store the status information;

[0007] A processing module monitors the target hazardous chemicals in real time according to the status information.

[0008] In some embodiments, the acquisition module includes: a temperature sensor, a pressure sensor, a liquid level sensor, and a gas concentration sensor.

[0009] In some embodiments, the state information includes: temperature parameters, pressure parameters, liquid level parameters, and gas concentration parameters.

[0010] In some embodiments, the transmission module transmits the status information via wireless communication.

[0011] In a second aspect, the present invention provides a method for supervising hazardous chemicals, comprising the following steps:

[0012] S1. Establish a basic information database of the target hazardous chemicals and store the basic information database in the storage module;

[0013] S2. Based on the basic information database and the status information, the target hazardous chemicals are monitored in real time by the processing module.

[0014] In some embodiments, the basic information library includes the name, storage conditions, chemical properties and storage time range of the target hazardous chemicals.

[0015] In some embodiments, when the target hazardous chemicals are monitored in real time through the processing module based on the basic information library and the status information, the processing module presets temperature parameter thresholds, pressure parameter thresholds, liquid level parameter thresholds and gas concentration parameter thresholds.

[0016] In some embodiments, when one of the temperature parameters, pressure parameters, liquid level parameters and gas concentration parameters detected in real time by the temperature sensor, pressure sensor, liquid level sensor and gas concentration sensor exceeds the corresponding parameter threshold, the processing module issues a first warning signal.

[0017] In some embodiments, when the storage time of the target hazardous chemical is greater than the storage time range, the processing module issues a second warning signal.

[0018] In some embodiments, when the processing module issues the first warning signal or the second warning signal, the processing module transmits the temperature parameters, pressure parameters, liquid level parameters, gas concentration parameters of the target hazardous chemicals and the name, storage conditions, chemical properties, and storage time range of the target hazardous chemicals to the display panel for display.

[0019] Compared with existing technologies, the present invention offers the following advantages: Real-time status information of hazardous chemicals is collected through acquisition modules (such as temperature sensors and pressure sensors), ensuring immediate understanding of the chemical's status. The processing module performs real-time analysis based on preset parameter thresholds and immediately issues a warning signal upon detecting an anomaly, effectively preventing accidents and improving safety. A basic information database, including the chemical's name, storage conditions, chemical properties, and storage time range, is established, providing comprehensive data support for regulatory oversight. The storage module stores collected status information, facilitating historical data query and trend analysis, providing a basis for decision-making. The transmission module utilizes wireless communication technology to achieve rapid and accurate transmission of status information, reducing wiring costs and increasing system flexibility and scalability. The processing module automatically processes and analyzes the collected data, determining the chemical's safety status based on preset conditions, alleviating the burden of manual monitoring. Using preset parameter thresholds, the system automatically identifies potential safety hazards, improving the accuracy and efficiency of regulatory oversight. When a warning signal is issued, the processing module transmits the relevant information to a display panel for display, allowing supervisors to intuitively understand the chemical's status and the reason for the warning. The visual interface simplifies operational processes, improving the convenience and responsiveness of regulatory oversight. This invention achieves all-round, all-weather supervision of hazardous chemicals, greatly improving the level of safety management. Through real-time monitoring and early warning, the probability of accidents is effectively reduced, ensuring the safety of personnel and the environment.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] See Figure 1-2 As shown, the first embodiment:

[0030] A hazardous chemicals supervision system according to an embodiment of the present application includes:

[0031] A collection module, which is used to collect status information of target hazardous chemicals in real time;

[0032] A transmission module, configured to transmit the collected status information;

[0033] a storage module, the storage module being configured to receive the status information transmitted by the transmission module and store the status information;

[0034] A processing module monitors the target hazardous chemicals in real time according to the status information.

[0035] In some specific embodiments, the acquisition module includes: a temperature sensor, a pressure sensor, a liquid level sensor, and a gas concentration sensor.

[0036] It should be understood that temperature sensors typically operate based on principles such as thermistors, thermocouples, or infrared. Taking a thermistor as an example, its resistance value changes with temperature. By measuring the change in resistance value and passing it through a corresponding conversion circuit, the corresponding temperature value can be obtained. When in contact with hazardous chemicals or in the surrounding storage environment, it can sense changes in ambient temperature and convert the temperature signal into an electrical signal for output. Real-time monitoring of the temperature of the environment in which hazardous chemicals are located can keep track of temperature conditions for temperature-sensitive chemicals, such as volatile and easily decomposable chemicals, to prevent abnormal temperatures from causing changes in chemical properties or dangerous situations caused by excessive volatilization. Temperature thresholds can be set, and once the temperature exceeds the safe range, an early warning can be issued, facilitating the implementation of appropriate measures, such as cooling and adjusting the storage environment.

[0037] Pressure sensors generally utilize the piezoresistive effect, capacitive principle, etc. For example, a piezoresistive pressure sensor, when subjected to pressure, will deform its internal pressure-sensitive element (such as a silicon diaphragm), causing a change in resistance value, and then convert the resistance change into a corresponding pressure signal output through the measuring circuit. It can be installed on the wall of a container storing hazardous chemicals or on related pipelines to sense the internal pressure conditions. The pressure sensor can monitor the pressure conditions in hazardous chemical storage containers in real time. For some chemicals stored at a specific pressure, it ensures that the pressure is always within a safe range to prevent dangerous situations such as container rupture and explosion due to excessive pressure, or air ingress due to low pressure, causing other chemical reactions. It helps to detect pressure anomalies in a timely manner so that pressure relief, pressurization and other operations can be performed to ensure safety.

[0038] Common liquid level sensors include ultrasonic, hydrostatic, and float types. Ultrasonic level sensors emit ultrasonic waves toward the liquid surface, receive the reflected ultrasonic signal, and calculate the liquid level based on the time difference. Hydrostatic level sensors use the principle that static pressure is proportional to the liquid level, inferring the liquid level by measuring pressure. Float level sensors rely on a float that rises and falls with the liquid level, converting the level change into an electrical signal through a connecting device. These sensors can be placed in containers storing hazardous chemicals to monitor the liquid level. Accurately monitoring the liquid level of hazardous chemicals prevents overflows and leaks caused by excessively high levels, or low levels that affect normal use. For chemical reactions or storage processes requiring precise liquid level control, these sensors provide accurate data support, facilitating timely replenishment or adjustment of the liquid level.

[0039] Different types of gas concentration sensors operate in different ways. For example, in a catalytic combustion gas sensor, when combustible gas comes into contact with the catalytic element on the sensor surface, a combustion reaction occurs, causing the sensor temperature to rise. The gas concentration is determined by measuring this temperature change. Electrochemical gas sensors utilize an electrochemical reaction between gases on the electrode surface, generating a current signal that correlates with the gas concentration. Placed within hazardous chemical storage spaces, they can monitor specific gas concentrations. Real-time monitoring of gas concentrations in the storage environment can prevent toxic and hazardous gases from exceeding acceptable concentrations, potentially harming humans and polluting the environment. For combustible gases, this can prevent concentrations from reaching the explosive limit and potentially causing an explosion. Abnormal gas concentrations can provide a timely warning, allowing ventilation and evacuation measures to be implemented.

[0040] In some specific embodiments, the state information includes: temperature parameters, pressure parameters, liquid level parameters, and gas concentration parameters.

[0041] In some specific embodiments, the transmission module transmits the status information via wireless communication.

[0042] It should be understood that the transmission module first modulates the status information (such as temperature, pressure, liquid level, and gas concentration) collected by the acquisition module. The purpose of modulation is to convert the original information signal into a signal format suitable for transmission over a wireless channel. For example, amplitude modulation (AM), frequency modulation (FM), or digital modulation (such as amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK)) can be used. Digital modulation, for example, converts binary status information data into corresponding amplitude, frequency, or phase variations of a high-frequency carrier signal for transmission over a wireless environment. The modulated signal is then loaded onto a radio frequency carrier and transmitted into space via an antenna as radio waves. The frequency range of the radio frequency carrier varies depending on the wireless communication standard. For example, common Wi-Fi operates in the 2.4 GHz or 5 GHz bands, Bluetooth operates in the 2.4 GHz band, and IoT communication technologies such as ZigBee may operate in specific low-power frequency bands. These radio waves propagate through the air, following the basic principles of electromagnetic wave propagation, including reflection, refraction, and diffraction, to cover a certain transmission distance. Radio waves propagate through space and reach the receiving end (such as the device housing the storage module or a remote monitoring center). During this propagation process, the signal is affected by various factors, such as distance attenuation, obstruction by obstacles, and interference. The wireless communication module at the receiving end receives these radio wave signals through an antenna. The receiving end demodulates the received RF signal, recovering the modulation information and obtaining the original state information data. For example, for a digitally modulated signal, the corresponding demodulation algorithm is used to recover the binary data. Then, according to the agreed data format and encoding rules, the binary data is parsed into specific state information such as temperature and pressure values, thus enabling wireless transmission of this state information.

[0043] Eliminating the need to lay extensive wired cables reduces wiring costs, effort, and time. Wireless communication makes it easy to connect devices and transmit data, particularly in difficult-to-reach locations, such as within existing hazardous chemical storage facilities and complex industrial sites. Collected status information can be quickly transmitted, avoiding the signal delays that can occur with wired transmission. For scenarios like hazardous chemical regulation, which require high real-time performance, wireless communication ensures that status information reaches storage and processing modules promptly, enabling supervisors to obtain the latest data, identify potential safety hazards, and take appropriate action. Additional data collection devices can be easily integrated. As the regulatory system continues to improve and the monitoring scope expands, the collection and transmission of more hazardous chemical status information can be achieved by simply adding new collection nodes to the existing wireless communication network and performing simple network configuration, making the system easy to upgrade and expand.

[0044] Second embodiment:

[0045] A method for monitoring hazardous chemicals according to an embodiment of the present application includes the following steps:

[0046] S1. Establish a basic information database of the target hazardous chemicals and store the basic information database in the storage module;

[0047] S2. Based on the basic information database and the status information, the target hazardous chemicals are monitored in real time by the processing module.

[0048] In some specific embodiments, the basic information library includes the name, storage conditions, chemical properties and storage time range of the target hazardous chemicals.

[0049] It should be understood that information such as the name, storage conditions, chemical properties, and storage time range of the target hazardous chemical should be obtained from sources such as the hazardous chemical's product insert, material safety data sheet (MSDS), specialized chemical materials, and relevant industry standards and specifications. For example, for a specific flammable liquid chemical, its product insert will clearly indicate the liquid's exact name, suitable storage temperature range, storage conditions such as substances to avoid contact, its chemical properties such as flash point and ignition point, and the recommended maximum storage time under normal storage conditions. For some newly emerging hazardous chemicals or where detailed information is lacking, accurate information may need to be obtained through experimental analysis or consultation with professional chemical research institutions or experts. The collected information should be organized according to a specific data structure, for example, in a database format, with the name of the hazardous chemical as the primary keyword and storage conditions, chemical properties, and storage time range as associated fields. This organized information should be accurately entered into the basic information database within the storage module using a specialized data entry system or software tool. During the data entry process, data verification and auditing can be performed to ensure accuracy and completeness.

[0050] Name information helps accurately identify hazardous chemicals, avoiding mishandling or misunderstandings caused by name confusion during the regulatory process. Accurate names clearly inform supervisors and operators about the type of chemical being handled. Storage condition information provides guidance on the proper storage of hazardous chemicals, including requirements for environmental factors such as temperature, humidity, light, and ventilation. For example, some chemicals require storage in a low-temperature, dry environment. Based on this information, appropriate storage facilities can be set up to prevent hazardous conditions such as deterioration and decomposition caused by improper storage conditions. Chemical property information helps supervisors and relevant personnel gain a deeper understanding of the hazards of chemicals, such as their flammability, explosiveness, toxicity, and corrosiveness, as well as the potential chemical reactions that may occur under different conditions. This facilitates the development of targeted safety measures, such as selecting appropriate fire extinguishing methods and equipping appropriate protective equipment. Storage time range information alerts personnel to promptly handle or replace chemicals, preventing them from exceeding their expiration date due to prolonged storage, leading to performance degradation and increased risks. During real-time monitoring, the processing module compares and analyzes the collected status information with the information in the basic information database. For example, when temperature data collected by a temperature sensor is compared with the appropriate storage temperature range for the chemical in the basic information database, a timely warning can be issued if any deviation occurs. Based on information such as chemical properties and storage time ranges, more appropriate regulatory strategies can be formulated. For example, for chemicals with active chemical properties and short storage times, monitoring frequency can be increased to ensure appropriate handling within the safe storage period.

[0051] In some specific embodiments, when the target hazardous chemicals are monitored in real time through the processing module based on the basic information library and the status information, the processing module presets temperature parameter thresholds, pressure parameter thresholds, liquid level parameter thresholds and gas concentration parameter thresholds.

[0052] In some specific embodiments, when one of the temperature parameters, pressure parameters, liquid level parameters and gas concentration parameters detected in real time by the temperature sensor, pressure sensor, liquid level sensor and gas concentration sensor exceeds the corresponding parameter threshold, the processing module issues a first warning signal.

[0053] In some specific embodiments, when the storage time of the target hazardous chemical is greater than the storage time range, the processing module issues a second warning signal.

[0054] In some specific embodiments, when the processing module issues the first warning signal or the second warning signal, the processing module transmits the temperature parameters, pressure parameters, liquid level parameters, gas concentration parameters of the target hazardous chemicals and the name, storage conditions, chemical properties, and storage time range of the target hazardous chemicals to the display panel for display.

[0055] It should be understood that the display panel combines real-time parameters with data from the basic information database to help supervisors quickly identify issues. For example, when a temperature exceeds a limit, the current temperature value, threshold, and chemical name are directly displayed to avoid confusion. When the storage time limit is exceeded, the remaining storage days are clearly displayed, prompting prompts for timely action. Through visual interfaces (such as tables, dashboards, and color coding), supervisors can grasp the full risk picture without having to consult multiple data sources. Alert details include action suggestions (such as "Immediately reduce temperature" and "Replace chemical") to guide on-site personnel to take quick action. The display panel records key data for each alert event (such as the limit value exceeded, the time of occurrence, and the chemical information), providing a basis for subsequent incident analysis. Historical alert records can be stored in a database and supported for query and export, facilitating safety management and compliance audits. The display panel can be deployed at a local monitoring center or at a remote terminal (such as a mobile app or computer software) to enable cross-regional monitoring. Supervisors can remotely view abnormal information through the panel, reducing the frequency of on-site inspections and mitigating safety risks. The data on chemical properties, storage conditions, and other aspects of the basic information database provides supervisors with a standardized reference to avoid misjudgments due to lack of experience.

[0056] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
