Description

Technical Field

[0001] The present invention relates to the field of nuclear power technology, and in particular to an intelligent chemical storage and management device. Background Art

[0002] A large number of chemicals, such as alcohol, cleaning agents, sealants, etc., are used in large industrial enterprises such as nuclear power plants. These chemicals not only have certain biological toxicity, but may also undergo chemical reactions with each other, which is a key point affecting the safe production of enterprises. Since chemicals are basically stored in special warehouses, during on-site construction, it is necessary to take the chemicals out of the warehouse and temporarily store them in on-site storage cabinets. After use, the remaining or empty chemicals are also temporarily stored in the on-site storage cabinets. In addition, chemicals have time limits, and the expiration date of the stored chemicals must be mastered to ensure that the chemicals are not expired when used on-site, and the expired chemicals in the storage cabinets are cleaned out in time. There are currently many types of chemical storage cabinets, including explosion-proof cabinets, corrosion-resistant cabinets, fireproof cabinets, etc. Although they can all store chemicals, there are still many shortcomings compared to current management expectations, such as:

[0003] No uninterrupted status monitoring: During the storage process, chemicals need to be monitored in real time to detect changes in parameters such as temperature and pressure in a timely manner, so as to deal with potential risks. Currently, this is achieved through regular inspections by personnel, and the coverage period is insufficient, resulting in the inability to fully and continuously monitor the status of stored chemicals, and the inability to deal with problems in a timely manner, which poses certain safety hazards.

[0004] Registration relies on manual operations, which may result in inadequate identification and unreasonable storage: some items that do not meet the storage requirements are prohibited from being placed in chemical storage cabinets, such as gas cylinders, flammable cloths, etc. However, the current access inspection for chemical storage cabinets depends on the cognitive level and sense of responsibility of users and registrars, which may lead to loopholes.

[0005] Chemical storage cabinet management requires frequent inspections and registrations, which takes up human resources: At present, chemical storage cabinets require a large number of personnel to conduct frequent inspections. For example, nuclear power plants require daily inspections, which results in high labor costs. Manual registration is generally used for in and out cabinet registration. If the registrant is not present, the items cannot be entered or exited, which is inconvenient to use. At least two full-time registrars are required for each cabinet, which results in certain labor costs.

[0006] Storage information is not shared, resulting in insufficient utilization of chemicals: Chemical storage and expiration information are all stored in paper registration books. This cannot be shared, resulting in the failure to prioritize the use of residual and expired chemicals, resulting in a waste of chemical resources. As chemicals are generally expensive, this increases the operating costs of enterprises. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide an intelligent chemical storage and management device, which realizes the uninterrupted status monitoring of chemical storage, ensures the timely discovery and handling of abnormal problems occurring in chemical storage, and saves the human resources of high-frequency inspections and registrars. In addition, intelligent registration management can be realized to improve convenience.

[0008] Compared with the prior art, the intelligent chemical storage and management device of the present invention has the following beneficial effects:

[0009] (1) Realizes uninterrupted safety status monitoring of chemicals in storage. Through the parameter monitoring and intervention components, the status of chemicals can be collected in real time 24 hours a day, and abnormalities can be intervened in time to ensure the safety of chemical storage.

[0010] (2) It realizes paperless, accurate and intelligent storage and retrieval of chemicals. Through the registration component, users can store and retrieve chemicals by themselves without contacting the administrator. At the same time, through the built-in list comparison, it prevents items that do not meet the requirements from entering the chemical storage cabinet.

[0011] (3) Intelligent expiration monitoring and remaining utilization of chemicals have been realized. Electronic calculation and reminder of expiration dates can prevent chemicals from being stored in cabinets beyond their expiration dates. At the same time, chemical storage information is shared, which improves the utilization rate of remaining chemicals. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The physical storage module includes a storage cabinet, a parameter monitoring and intervention component, an on-site alarm component, and an on-site monitoring component. The functions and logical relationships of each submodule are detailed in Figure 2 .

[0025] The appearance and structure of the storage cabinet are shown in Figure 3 . Material selection and processing are carried out according to the relevant requirements of the national standard explosion-proof cabinet.

[0026] The storage cabinet is provided with a plurality of independent storage compartments, each of which is separated by steel plates and columns. Each storage compartment is provided with a small vent, which is connected to the large vent on the cabinet body through a pipe and is connected to the explosion-proof fan 8 on the cabinet body 1, so as to realize air pressure monitoring and control in the storage compartment;

[0027] The storage cells are provided with non-repeating numbers;

[0028] In accordance with the storage items, the storage grids are divided into 2 large storage grids, 3 medium storage grids and 4 small storage grids.

[0029] The cabinet body 1 is provided with a hanging screw hole on the top, a grounding anti-static connector on the outer shell, and a plurality of rollers 6 and a locking device on the bottom of the cabinet body 1 to ensure that the cabinet has the ability to move;

[0030] The cabinet 1 is provided with a power connector and an explosion-proof cable, which are connected to the external power supply port on one hand and to the power line of the parameter monitoring and intervention components in the storage compartment on the other hand, thereby achieving 24-hour uninterrupted operation.

[0031] The parameter monitoring and intervention component is used to monitor and intervene in the chemical state parameters in the storage cabinet, including temperature, pressure and humidity. A temperature probe, a pressure probe and a humidity meter are set in each storage compartment. Continuous monitoring can be carried out, and the results are sent to the control management module and the display / use module. The standards of the three parameters are entered in the control management module. Once the standard is exceeded, a reminder and intervention are triggered. For example, if the temperature alarm is triggered, the air conditioner 7 installed on the storage cabinet is started. If the pressure and humidity alarms are triggered, the explosion-proof fan 8 installed on the storage cabinet is started.

[0032] The local alarm component 9 refers to an explosion-proof buzzer, a hazard indicator light, and related wires and signal lines; it is installed on the top of the storage cabinet, receives the signal from the control management module 5 and triggers an audible and visual alarm; once a parameter exceeds the standard, an on-site audible and visual alarm will be triggered to remind management and inspection personnel to deal with the abnormality in time.

[0033] The on-site monitoring component is installed on the top of the storage cabinet and is used to photograph the use of the device, and the photographing results are transmitted to the display and use module.

[0034] The function of the control management module is to realize the intelligent registration and management of chemicals. It includes the registration component and the control component. The overall logic is shown in Figure 4 .

[0035] The registration component is installed on the cabinet body 1 of the storage cabinet and is used for the access registration of personnel and items. The specific form is shown in Figure 5 .

[0036] The registration component includes four sub-components, namely, the identity recognition component, the item scanning component, the interactive display screen and the smart lock;

[0037] The identity recognition component scans and reads the face information, searches the information database, and records the user's identity information;

[0038] The item scanning component adopts the QR code reading and writing principle. The QR code reading and writing module reads the content of the item label detected by the QR code scanning antenna and records the information in the ledger;

[0039] Interactive display screen for information input and display of error and alarm information;

[0040] The smart lock is installed on each storage compartment, receives the signal from the control component, and opens and closes;

[0041] In the control component, enter the face information database for factory access. The identity recognition component scans and reads the face information, searches in the information database, and records the user's identity information, including name, contact information, and department. People who are not in the face information database cannot use the storage cabinet, thus realizing reliable access management of personnel. QR codes are affixed to the chemicals in the factory. The item scanning component adopts the QR code reading and writing principle. The QR code reading and writing module reads the item label content detected by the QR code scanning antenna, including the item name, volume, and expiration date, and records the information in the ledger. The interactive display has two major functions. On the one hand, it can input information (the display is a touch screen and can be clicked), mainly the remaining amount information of the item, such as 50% of the alcohol in a bottle of alcohol stored. On the other hand, it can display error and alarm information, such as the item is not in the factory chemical list, so as to inform the user that it cannot be stored or the specific problems encountered in storage. Both the identity recognition component and the item scanning component are equipped with photosensitive lights, which will automatically emit light when recognizing user operations to ensure sufficient light. The smart lock is installed on each storage compartment, which receives the signal from the control component and opens and closes.

[0042] The control component is used for registration and security management, including a computer, a controller, a power line and a signal line;

[0043] The control software is installed on the computer and the controller. After the computer and the controller are connected to the same local area network via a wired or wireless network, the control software is operated on the computer.

[0044] The operation of the control software on the computer includes importing the factory access facial information database, importing the factory access chemical information database, setting the alarm range of chemical monitoring parameters, and setting the reminder time for chemical expiration; the controller receives the set parameters and compares them with the information sent by the parameter monitoring and intervention component and the registration component; if any parameter exceeds the standard, an alarm signal is sent to the local alarm and display use module; if the registered person or item is not in the input access list, the smart lock will be notified not to unlock, and the reason for not unlocking will be displayed on the interactive display screen.

[0045] The display and use module is used to display and notify the use of the chemical storage cabinet. This module is mainly in the form of software. Figure 6 . It includes the following four aspects:

[0046] The first is the chemical storage and access ledger. The webpage receives the chemical registration ledger list sent by the registration component, including personnel, access time, item name, material code, quantity, remaining quantity, expiration date, and storage cell number. Users can query and download the list to understand the access record and current status of the chemicals in the storage cabinet.

[0047] This module also records the parameters of the storage cabinet, including temperature, pressure and humidity, with real-time records and trend inquiries based on user-defined time periods, so as to understand the status of chemicals stored in the cabinet.

[0048] This module also displays the surveillance video from the on-site monitoring component, so that users can remotely monitor the use of the chemical storage cabinet.

[0049] This module also shows the Priority Items window, which displays two types of information:

[0050] The first is a list of chemicals recommended for priority use, including chemicals that are nearing their expiration date and chemicals with a remaining quantity of less than 100%.

[0051] The second is a list of chemicals that need to be stored for a long time. This device is used for the temporary storage of chemicals, and it is required that the storage time of chemicals does not exceed the allowed time to avoid occupying storage resources and reduce the risk of chemical failure.

[0052] This module will automatically compile a list of chemicals that are about to expire, and notify the depositor and chemical manager according to the set reminder date to avoid chemicals from becoming ineffective over the expiration date.
