[0031] The cabinet 1 is provided with an identification chamber 11, a storage chamber 12 and an explosion-proof chamber 13, which are interconnected, a first switch door 14 is provided at one end of the identification chamber 11, a second switch door 15 is provided between the identification chamber 11 and the storage chamber 12, a third switch door 16 is provided between the storage chamber 12 and the explosion-proof chamber 13, and an emergency switch door 17 is provided in the storage chamber 12. Among them, the first switch door 14, the second switch door 15, the third switch door 16 and the emergency switch door 17 are all explosion-proof electric doors, which are special door bodies designed for storing and handling hazardous chemicals, and which combine explosion-proof technology and electric control technology to ensure effective safety isolation and protection in hazardous environments.

[0032] The door body of explosion-proof electric door is made of explosion-proof materials, such as steel, stainless steel or aluminum alloy. These materials have the characteristics of high strength, corrosion resistance and high temperature resistance, and can effectively resist the erosion of explosion shock waves and high temperature flames.

[0033] The structure is compact and strong, able to withstand greater pressure and explosion force, ensuring that the door body will not break or deform when an explosion occurs.

[0034] The temperature and humidity controller 2 is connected to the storage chamber 12 and the explosion-proof chamber 13 and is used to control the ambient temperature and humidity inside the storage chamber 12 and the explosion-proof chamber 13 .

[0035] The transfer device 3 is disposed in the cabinet 1 and is used to transfer hazardous chemicals between the identification chamber 11 , the storage chamber 12 and the explosion-proof chamber 13 .

[0036] The identification device 4 is disposed in the identification cavity 11 and is used to obtain product label images of hazardous chemicals.

[0037] The sensor module is used to obtain environmental parameters in the storage chamber 12 and the explosion-proof chamber 13, storage location information of hazardous chemicals, and parameters of storage status of hazardous chemicals.

[0038] The communication module is connected to the network to obtain network data.

[0039] The monitoring system is electrically connected to the first switch door 14, the second switch door 15, the third switch door 16, the emergency switch door 17, the temperature and humidity controller 2, the identification device 4, the sensor module, the communication module and the power supply; the monitoring system is used for data processing and controlling the on and off of the first switch door 14, the second switch door 15, the third switch door 16, the emergency switch door 17, the temperature and humidity controller 2, the identification device 4, the sensor module and the communication module and the power supply.

[0040] The power supply is connected to the mains system for storing and providing electrical energy.

[0041] The identification chamber 11, storage chamber 12 and explosion-proof chamber 13 are combined in a cabinet 1 to form a connected whole, and the transfer device 3 and multiple switch doors are used to realize the transfer of hazardous chemicals between the chambers. It can not only realize the safe identification and storage of hazardous chemicals, but also quickly isolate hazardous chemicals into the explosion-proof chamber 13 when an abnormality occurs, ensuring safety.

[0042] The identification device 4 automatically obtains the product label image of the hazardous chemicals, and the monitoring system automatically identifies and records the hazardous chemicals information. The sensor module monitors the storage status of the hazardous chemicals in real time, and combines with the communication module to obtain the physical and chemical properties and safe storage requirements of the external network. Combined with information and intelligent management, the accuracy and real-time performance of hazardous chemicals management are greatly improved.

[0043] The temperature and humidity controller 2 automatically adjusts the environmental conditions inside the storage chamber 12 and the explosion-proof chamber 13 according to the physical and chemical properties of the hazardous chemicals to ensure that the hazardous chemicals are in a safe storage environment. At the same time, when the storage status of hazardous chemicals is abnormal, the system can automatically alarm and execute emergency procedures, such as transferring abnormal hazardous chemicals to the explosion-proof chamber 13, which improves the safety and emergency response capabilities of the overall system.

[0044] Working method of hazardous chemicals storage cabinet:

[0045] A. Control the first switch door 14 to open, the operator places the hazardous chemicals in the identification chamber 11, controls the first switch door 14 to close, obtains the product label image of the hazardous chemicals through the identification device 4 and feeds it back to the monitoring system, and the monitoring system obtains the hazardous chemical information from the fed-back image and saves it.

[0046] B. The monitoring system controls the second switch door 15 to open, controls the transfer device 3 to place the hazardous chemicals from the identification chamber 11 into the storage chamber 12 through the second switch door 15, controls the second switch door 15 to close, and the sensor module records the storage location of the hazardous chemicals and continuously obtains the parameters of the storage status of the hazardous chemicals and feeds them back to the monitoring system in real time. The monitoring system implements monitoring of the parameters of the storage status of the hazardous chemicals.

[0047] C. The communication module obtains the physical and chemical properties and safe storage requirements of the hazardous chemicals placed in the storage cavity 12 through the network and feeds them back to the monitoring system. The monitoring system sets the safety thresholds and alarm rules of the hazardous chemicals according to the physical and chemical properties and safe storage requirements of the hazardous chemicals, and controls the temperature and humidity controller 2 to adjust the temperature and humidity inside the storage cavity 12 accordingly to ensure that the hazardous chemicals remain within the safety threshold range.

[0048] D. When the parameters of the hazardous chemicals storage status are abnormal or exceed the safety threshold, the monitoring system will sound an alarm according to the alarm rules and notify the operator through the communication module and then start timing.

[0049] E. If an operator comes to handle the situation within the preset time, the timing is canceled. If no operator comes to handle the situation after the preset time, the third switch door 16 is controlled to be opened, and the transfer device 3 is controlled to transfer the abnormal hazardous chemicals from the storage chamber 12 to the explosion-proof chamber 13 through the third switch door 16. The third switch door 16 is controlled to be closed, and the operator and the emergency contact are continuously notified through the communication module.

[0050] Specifically, the explosion-proof cavity 13 includes an anti-corrosion and rupture layer, a buffer layer, a reinforcement layer, a pressure relief layer, a heat insulation layer and an anti-tear layer arranged from the inside to the outside.

[0051] The anti-corrosion rupture layer is used to prevent hazardous chemicals from corroding the explosion-proof cavity 13. The anti-corrosion rupture layer is provided with a rupture groove, which guides the flow direction of the pressure so that the anti-corrosion rupture layer is destroyed at a predetermined position, thereby guiding the pressure inside the explosion-proof cavity 13. The anti-corrosion rupture layer is made of anti-corrosion materials, such as high molecular materials such as polytetrafluoroethylene (PTFE) and polyethylene (PE), and has good corrosion resistance and controllable rupture performance.

[0052] The buffer layer is used to buffer and disperse the pressure inside the explosion-proof cavity 13, reducing the destructiveness of the pressure inside the explosion-proof cavity 13. Specifically, the buffer layer is made of a buffer material, such as polyurethane foam, rubber or elastomeric material. The buffer layer has good elasticity and energy absorption capacity, which can effectively slow down the transmission of shock waves and reduce the damage to the explosion-proof cavity 13.

[0053] The reinforcement layer is made of a rigid material and is used to support the buffer layer, so as to disperse and absorb the pressure inside the explosion-proof cavity 13. The reinforcement layer includes stainless steel, aluminum alloy or high-strength alloy steel. The reinforcement layer is not only high in strength, but also has good corrosion resistance, and can withstand the pressure inside the explosion-proof cavity 13 for a long time.

[0054] A plurality of pressure relief plates are arranged at intervals inside the pressure relief layer to disperse the pressure inside the pressure relief layer, and the pressure relief layer is provided with a plurality of pressure relief valves connected to the outside. When the pressure inside the pressure relief layer reaches the preset opening pressure of the pressure relief valve, the pressure inside the pressure relief layer is dispersed by the plurality of pressure relief plates and discharged to the outside through the pressure relief valve.

[0055] The heat insulation layer is used to isolate the heat generated by the explosion inside the explosion-proof cavity 13. The heat insulation layer is a high-efficiency heat insulation material, such as ceramic fiber, aerogel, vacuum insulation board, etc. The heat insulation layer can effectively isolate high temperature, reduce the heat transfer to the outside of the explosion-proof cavity 13, and protect the surrounding environment and equipment from high temperature damage.

[0056] The tear-resistant layer is used to reinforce the explosion-proof cavity 13, so that the explosion-proof cavity 13 is not easy to break. The tear-resistant layer is made of a material with high tensile strength and tear-resistant performance, such as aramid fiber, ultra-high molecular weight polyethylene (UHMWPE) fiber and other high-performance synthetic fiber materials. The tear-resistant layer has excellent mechanical properties and can effectively resist external or internal impact and tearing.

[0057] During operation, when abnormal hazardous chemicals explode in the explosion-proof chamber 13, the explosion pressure destroys the corrosion-resistant rupture layer through the rupture groove at the predetermined position and enters the buffer layer. The buffer layer buffers and disperses the explosion pressure and then enters the pressure relief layer. The dispersed pressure bends multiple pressure relief plates to further reduce the pressure. If the dispersed pressure is still higher than the preset opening pressure of the pressure relief valve, the pressure inside the pressure relief layer is discharged outward through the pressure relief valve.

[0058] The present application improves the safety of hazardous chemicals storage, and effectively reduces the potential safety hazards that may occur during the storage of hazardous chemicals through the multi-layer protection and intelligent monitoring system of the identification chamber 11, storage chamber 12 and explosion-proof chamber 13. Once an abnormality occurs, the storage cabinet automatically responds and transfers the hazardous chemicals to the explosion-proof chamber 13 to prevent the accident from spreading.

[0059] Enhance the intelligence and efficiency of hazardous chemicals management, and use identification devices 4, sensor modules, communication modules, etc. to realize the full-process automated management of hazardous chemicals, from identification, storage to monitoring, to achieve efficient operation procedures, reduce the error rate of manual operations, and can obtain and update the safety storage requirements of hazardous chemicals in real time to ensure the timeliness and accuracy of management.

[0060] Optimize the storage environment of hazardous chemicals, automatically adjust the temperature and humidity environment in the storage chamber 12 and the explosion-proof chamber 13 through the temperature and humidity controller 2, ensure that the hazardous chemicals are in the best storage conditions, extend their service life and prevent safety problems caused by improper storage.

[0061] Among them, the communication module is a conventional 4G / 5G communication module and / or a conventional Wi-Fi module. Conventional wireless communication modules, such as 4G or 5G modules provided by manufacturers such as SIMCom and Quectel, can achieve high-speed data transmission between the device and the remote monitoring center. They usually integrate a TCP / IP protocol stack, support multiple communication protocols such as SMS, HTTP, FTP, etc., and are widely used in IoT devices.

[0062] Conventional Wi-Fi modules such as ESP8266, ESP32 and other Wi-Fi modules support wireless LAN communication and are suitable for data exchange with local network devices or servers within the LAN. They are suitable for short-distance communication or scenarios where remote monitoring is not required.

[0063] The monitoring system is an embedded monitoring system, industrial controller or SCADA system. Embedded monitoring system: Single-board computers such as Raspberry Pi and BeagleBone can serve as the core of the monitoring system, run customized monitoring software, process sensor data, execute control commands, and upload data through communication modules.

[0064] Industrial controller: Programmable logic controller, or PLC for short, such as Siemens S7-1200, is widely used in industrial automation and can stably and reliably collect sensor data, perform logic control, and communicate with external devices. It is suitable for scenarios with high requirements for system stability and real-time performance.

[0065] SCADA system: Industrial monitoring and data acquisition systems such as GE's iFIX and Schneider Electric's Wonderware can be used as monitoring platforms for large systems, providing visual monitoring, alarm management, and data analysis functions. They are suitable for deployment in complex industrial environments.

[0066] The power supply is an uninterruptible power supply, a DC regulated power supply or a lithium battery pack.

[0067] Uninterruptible power supply, referred to as UPS, is commonly found in industrial control equipment. For example, UPS systems provided by APC and Eaton can provide a stable power supply for the equipment and provide short-term backup power when the city power is cut off, ensuring uninterrupted operation of key equipment.

[0068] DC regulated power supplies, such as those produced by Mean Well or TDK-Lambda, are widely used to provide stable DC power output for low-voltage electronic equipment, with voltages ranging from 5V, 12V to 24V.

[0069] Lithium battery packs are used for portable devices or emergency power supply after power outages. For example, lithium battery modules from Tesla Powerwall or LG Chem can be used as energy storage devices, charging when the mains power is normal and discharging to provide power during power outages.

[0070] like Figure 1 As shown, the monitoring system of this embodiment monitors the working time of the temperature and humidity controller 2 and the frequency of adjusting the ambient temperature and humidity.

The temperature detector is used to detect temperature, the humidity detector is used to detect humidity, and the gas concentration detector is used to detect gas concentration. Through multiple monitoring data points, the sensor module can obtain environmental parameters in the storage cavity 12.

[0072] The monitoring system is provided with a hazardous goods safety risk assessment model, through which the impact of changes in environmental conditions on the working pressure of the temperature and humidity controller 2 is assessed, and the assessment results of the hazardous goods safety risk assessment model are notified to the operator through the communication module.

[0073] The calculation formula of the dangerous goods safety risk assessment model is:

[0074] Risk Score=α·Environmental Risk Index+β·Controller Stress Index;

[0075] Environmental Risk Index is the environmental risk index.

[0076] Controller Stress Index is the controller stress index.

[0079] in,

[0080] N is the number of monitoring data points, and N is greater than 1.

[0081] i represents the monitoring data point, Temp i is the temperature value of the i-th monitoring data point, Hum i is the humidity value of the ith monitoring data point, GasConc ij is the concentration value of the jth gas in the ith monitoring data point.

[0085] In this embodiment, Temp safe =20℃, Temp range =5℃ (i.e. 17.5℃ to 22.5℃), Hum safe =50%, Hum range = 10% (i.e. 45% to 55%), GasThresh j =5%, w temp =0.4, w hum =0.3, w gasj =0.3Example.

[0086] in,

[0092] In this embodiment, the value of Max Work Hours is 12 hours, the value of Max Adjustment Frequency is 12 times / day, and the value of y is 0.5.

[0093] The evaluation results of the dangerous goods safety risk evaluation model of this embodiment are divided into multiple risk levels, and each risk level is low risk, medium-low risk, medium risk, medium-high risk and high risk;

[0094] The value range of low risk is between 0-1.0, which means that the environment of cabinet 1 is stable, the temperature and humidity controller 2 works normally, and the safety risk is extremely low;

[0095] The value range of medium-low risk is between 1.0 and 2.0, which means that the environment of cabinet 1 is basically stable, but there are slight fluctuations, the workload of temperature and humidity controller 2 is moderate, and the safety risk is low;

[0096] The value range of medium risk is between 2.0 and 3.0, which means that the environment of cabinet 1 has fluctuated to a certain extent, and the workload of temperature and humidity controller 2 is high, which requires attention and possible measures;

[0122] like Figure 3 As shown, this embodiment also includes a neutralizer spraying mechanism 5, which is electrically connected to the monitoring system and is used to spray a neutralizer on hazardous chemicals in an abnormal state to neutralize or dilute the harmful substances generated by leakage or reaction;

[0123] The neutralizer spraying mechanism 5 includes a storage tank 51, a pressure pump 52, a first conduit 53, a first spraying switch 54 and a spraying head 55;

[0124] The storage tank 51 is used to store the neutralizing agent;
