Description

Technical Field

[0001] The present invention relates to the technical field of coal mining, and particularly to a mine intelligent working face material management device and method. Background Art

[0002] In the production process of an intelligent coal mine working face, material management is not only the key to ensuring operation efficiency but also the top priority for ensuring production safety, especially with higher requirements for explosion-proof characteristics. However, traditional mine material management methods face severe challenges in this field. They are often inefficient, have insufficient data accuracy, and have obvious shortcomings in explosion-proof safety, which together hinder the realization of real-time and effective monitoring and management. Notably, traditional underground material management systems have obvious defects in explosion-proof safety. They cannot accurately and reliably identify and record the personnel who take materials, resulting in loopholes in explosion-proof safety supervision during the material usage process. At the same time, these systems are also difficult to achieve scientific classification, precise positioning, and effective management of scattered materials, further exacerbating explosion-proof safety hazards. In terms of quantity statistics and inventory checks, traditional methods are also inadequate. They cannot provide real-time and accurate underground material usage information, leading to lax control of inbound and outbound, and it is difficult to grasp the reserve situation of key materials in real time. More seriously, these traditional methods are extremely vulnerable to human errors, resulting in frequent explosion-proof safety loopholes in the material management process, posing a great threat to production safety. Therefore, for material management in the production process of an intelligent working face, strengthening explosion-proof characteristics, improving management efficiency, and ensuring data accuracy and security have become urgent tasks.

[0003] Traditional underground working face mine material cabinets have significant deficiencies in explosion-proof characteristics. They rely on physical keys for opening, which not only lacks the functions of classified management and preservation but also in the dim and potentially explosive underground environment, physical keys are extremely easy to lose, resulting in great difficulties in material management and time-consuming and laborious searching for required materials. In the management of materials and tools, traditional methods rely too much on manual records, which are not only inefficient, error-prone, but also have great potential hazards in explosion-proof safety. Manual records are difficult to ensure the accuracy and integrity of data. Once an error occurs, it may lead to over-withdrawal or mis-withdrawal of materials, wasting resources and even possibly causing safety accidents due to chaotic material management.

[0004] In addition, traditional underground working face material management methods also have inherent defects such as low efficiency, error-proneness, and difficulty in tracking, which are particularly prominent in explosion-proof safety. They limit the adaptability and flexibility of the material management system, making the mine working face appear powerless in dealing with complex and changeable production environments.

[0005] With the rapid development of coal mine intelligent technology, higher requirements are put forward for the management of materials in the mine working face. It not only requires high efficiency and flexibility, but also requires strong explosion-proof safety performance. However, the existing material cabinets in the underground working face still stay in the pure mechanical operation stage, lacking effective expandability and custom combination ability, and even more lacking interfaces connected to the information system. Therefore, they cannot meet the development needs of the intelligent working face. To sum up, the traditional underground working face mine material cabinets have obvious deficiencies in explosion-proof characteristics, management efficiency, accuracy, and adaptability, and urgent intelligent transformation and upgrading are needed.

[0045] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] The following will be combined with the attached Figures 1-5 , and will detail the technical solutions provided by the embodiments of the present invention.

[0047] As shown in the attached Figure 1 , an embodiment of the present invention provides a mine intelligent working face material management device, which includes: one or more storage devices 10, a main control module 20 and a server 30, where:

[0048] On one or more storage devices 10, a plurality of storage spaces 100 are provided. Inside each storage space 100, a gravity detection device 101 and a counting device 102 are provided, which are respectively used to detect the weight and quantity of materials in each storage space 100. An electronic lock is provided in each storage space 100 for switching control when taking or storing materials in each storage space 100. One or more reading and writing modules 80 are correspondingly provided on one or more storage devices 10, which are used to scan the information of materials in each storage space 100 and transmit the scanned information to the main control module 20; the main control module 20 stores the maximum storage threshold and the minimum storage threshold of the weight and quantity of materials in each storage space 100 input from the outside, so as to compare the maximum storage threshold and the minimum storage threshold with the quantity of materials detected by the gravity detection device 101 and the counting device 102 in each storage space 100. When the comparison result is equal to the maximum storage threshold, a voice or video reminder is issued, and no more materials are added to the storage space 100 equal to the maximum storage threshold. When the comparison result is less than or equal to the minimum storage threshold, a voice or video reminder is issued, and the storage space 100 less than or equal to the minimum storage threshold is replenished with materials to the corresponding maximum storage threshold. An alarm module is also provided on the main control module 20 for giving an early warning when the taking or storing of materials in the storage space 100 is abnormal; the server 30 is used to provide services for data interaction between the main control module 20 and one or more storage devices 10.

[0049] Thus, in a kind of intelligent working face material management device for mines of the present invention, by providing one or more storage devices 10 and providing a plurality of storage spaces 100 on one or more storage devices 10 to store materials, the classified control of materials is realized. By setting an electronic lock on each storage space 100, the loss of materials after being stored in the storage space 100 is avoided. By providing a gravity detection device 101 and a counting device 102, the timely replenishment of materials in the storage space 100 can be realized, ensuring the operation efficiency. At the same time, through the alarm module, when the taking or storing of materials in the storage space 100 is abnormal, an early warning is issued, which can realize the accurate management of materials, avoid the waste and damage of materials, and ensure the safety of the operation environment and operation personnel.

[0050] Specifically, material management includes the statistics of material storage, which facilitates the picking and storing of materials, reduces the loss of materials and the losses caused by such losses, affects the operation progress, ensures the safety of materials and the safety of operations. The purpose is to accurately manage materials, reduce material waste and storage chaos, reduce storage time, improve the picking and storing efficiency, enhance the flexibility and adaptability of material storage, and more importantly, to realize the intelligentization, precision and safety of material management in the mine working face, and ensure safe and stable operation in an explosive gas or dust environment.

[0051] In some alternative implementation manners of this embodiment, the main control module 20 includes a PLC controller or a PLC control system.

[0052] As an example, as Figures 2-4 shown, the storage device 10 of the present invention includes a material cabinet. The storage space 100 on the storage device 10 includes material boxes or material compartments on the material cabinet. In order to enable the storage device 10 to adapt to the coal mine operation environment, the storage device 10 is set as a mine explosion-proof and intrinsically safe control box. The mine explosion-proof and intrinsically safe control box is made of high-strength stainless steel material and its surface is treated by electrostatic spraying. Its cabinet base is designed to be wide and firm, providing a larger support area, effectively reducing the center of gravity, and thus greatly enhancing its stability. The base is made of high-strength and corrosion-resistant stainless steel. Reinforcing ribs are arranged inside the cabinet body to improve the strength of the overall structure. Anchor bolts or expansion bolts are used to fix the material cabinet to the ground, eliminating the risk of displacement caused by vibration. In addition, shock pads are added and advanced methods such as elastic connection are adopted to reduce the potential impact of vibration on the cabinet body, ensuring the safety and explosion-proof safety in the underground environment. Therefore, it is ensured that in the extreme environment where explosion-proof and corrosion resistance are required in the underground working face, its performance and stability can still be maintained, ensuring stable operation and data communication in the extreme underground environment.

[0053] As an example, in order to enable the storage device 10 to store materials of different sizes, the sizes of the material boxes or material compartments are set to be the same or different, so as to meet and adapt to the storage requirements of materials of different sizes.

[0054] As another example, in order to adapt to the storage requirements of items of different sizes, the grids of the material cabinet are specially designed as adjustable shelves. This flexible configuration enables the cabinet to easily accommodate various items from small parts to large equipment and can be adjusted at any time according to actual needs to meet the dynamically changing storage requirements.

[0055] It should be noted that the number of storage devices 10 is selected according to actual needs. The storage device 10 can be set to one or more according to actual needs. One or more storage devices 10 can be set together in one place or in different places, but one or more storage devices 10 share the same main control device and the same server 30. In this way, when extracting materials, the materials in the storage device 10 can be centrally managed and controlled through the same server 30 and the same main control device, reducing the deviation and impact of data conversion and data transmission, and improving the precise control of materials.

[0056] As some optional implementation manners of this embodiment, the above storage device 10 is set as a main cabinet and a sub-cabinet. The main cabinet and the sub-cabinet are set at the same position and are powered by the same power supply. At the same time, in order to further improve the management efficiency of materials, the main cabinet and the sub-cabinet can be marked and distinguished according to the attributes or sizes of the materials to achieve the primary classification of materials. Then, combined with the multiple material cabinets or material grids of different sizes on the main cabinet and the sub-cabinet, or refined zoning is carried out according to the types and uses of materials, such as the electrical equipment area, the safety equipment area, the tool area, and the maintenance supplies area, etc., aiming to reduce the search time and avoid the risks of losses or misuses that may be caused by the mixed placement of items. Thus, the refined secondary or multi-level classification management of materials is further realized to ensure that various necessary materials can be efficiently and safely stored and managed in the complex and changeable mine environment.

[0057] As some optional implementation manners of this embodiment, the PLC host built in the main cabinet is designed and manufactured in strict accordance with standards such as GB / T3836.1-2010, GB / T3836.2-2010 and GB / T3836.4-2010. It is installed in the explosion-proof cavity of the storage device 10 integrating the flameproof cavity and the intrinsically safe cavity. Through the unique nozzle design, it effectively isolates the explosion risk brought by external signals, and further improves the explosion-proof level of the device. The central control unit 203CPU equipped inside the device, as the core of information processing and decision-making, not only efficiently receives and processes various types of information from the main cabinet and the sub-cabinet, but also quickly formulates and executes reasonable control instructions according to this information to ensure the efficient and accurate operation of the entire system. To ensure the reliable and efficient transmission of information, the system adopts advanced communication protocols and modules, supporting both wireless and wired communication methods, enabling the main cabinet to real-time master the status and inventory information of the sub-cabinet, and greatly improving the real-time monitoring and dynamic management capabilities of the material management system. The design of the sub-cabinet also follows high standards and interface specifications. It is not only perfectly compatible and interchangeable with the main cabinet, but also highly consistent in appearance, size and functional modules, facilitating the flexible expansion and combination of the system. The modular design concept enables the sub-cabinet to work independently or freely combine with other functional modules, further enhancing the flexibility and expandability of the system. When adding or deleting a sub-cabinet, the system can automatically complete identification and configuration, including identity verification, status detection and function testing, ensuring that the new sub-cabinet seamlessly integrates into the existing system without large-scale modification, truly realizing the flexibility, efficiency and safety of the material management system.

[0058] To ensure the safe and stable operation of the storage device 10, a certain number of heat dissipation holes are designed on the side wall, back panel or top of the storage device 10 for hot air circulation to ensure effective heat dissipation without reducing the explosion-proof performance of the device. The outer shell and internal structure materials of the material cabinet are selected from materials with good heat conduction performance to improve the heat conduction efficiency.

[0059] To further improve the heat dissipation efficiency, a reasonable air duct can also be designed inside the material cabinet to guide the hot air circulation and avoid local heat accumulation. However, the air duct design should consider the layout and heat dissipation requirements of the internal equipment of the material cabinet to ensure that the hot air can be discharged smoothly, and at the same time, the explosion-proof safety characteristics of the storage device 10 should also be guaranteed.

[0060] In some optional implementation manners of this embodiment, the gravity detection device 101 includes a weight sensor, and the counting device 102 includes a counting sensor.

[0061] In order to adapt to the harsh environment of coal mine operations, the above-mentioned gravity detection device 101 and the above-mentioned weight detection sensor are set as intrinsically safe mine weight and counting sensors for real-time monitoring and management of the materials stored therein. The intrinsically safe mine weight sensor adopts strain gauge technology, which can provide accurate measurement results, and can avoid the safety risks brought by material waste and overloading. The design of this sensor complies with the intrinsically safe design standard and can operate safely even in flammable and explosive environments. It usually operates at low voltage to reduce the risk of explosion caused by electric sparks. In addition to the intrinsically safe design, the intrinsically safe mine weight sensor usually also has protection functions such as waterproof and dustproof to adapt to the harsh mine environment and ensure long-term stable operation. The intrinsically safe mine weight sensor is installed at the bottom of the storage bin to monitor the weight change of the materials in the bin by measuring the gravity of the materials, while the mine counting sensor realizes the counting function by identifying the increase or decrease in the number of items.

[0062] In order to further accurately and clearly illustrate the technical solution of the present invention, the functions and principles of the counting LED lamp, the gravity detection device 101, and the counting device 102 are described separately as follows:

[0063] Counting LED lamp: Its operation depends on the state of the electronic lock. When the electronic lock is opened, it starts counting and lights up; when the electronic lock is closed, the counting stops and it goes out. The accuracy of counting is based on the situation of manual operation of materials during the opening of the electronic lock. It does not directly sense the materials themselves, but defines the counting range through time intervals.

[0064] Gravity detection device 101: It measures the weight of the materials in the storage space by using a gravity sensor. Assuming that the weight of each material is relatively fixed, by dividing the change in weight by the weight of a single material, the increase or decrease in the number of materials can be estimated.

[0065] Counting device 102: It uses special counting technology and does not depend on the weight of the materials, but directly identifies and counts the individual materials.

[0066] According to the analysis of the above principles and functions, although these three devices are all related to material counting, they are not completely repetitive. The counting LED lamp focuses on the counting prompt during the operation process, the gravity detection device indirectly counts through weight changes, and the counting device directly and accurately counts. Through the mutual cooperation of the counting LED lamp, the gravity detection device 101, and the counting device 102, the accuracy and reliability of material management can be improved. Exemplarily, for example: the counting LED lamp can be used as a on-site prompt tool for operators, the gravity detection device can real-time monitor the overall change of materials, and the counting device provides accurate quantity data.

[0067] In order to count the increase or decrease of materials in each storage space 100, a counting LED light is provided on each storage space 100, and the counting LED light is connected to the main control module 20. Such a configuration enables the counting LED light to accurately count the materials in each storage space 100 when taking or storing them. When the electronic lock in each storage space 100 is opened, the counting LED light automatically lights up to count, and when the electronic lock of each storage space 100 is closed, the counting LED light automatically turns off. In addition, when materials are taken out of or put into the storage space 100 of the storage device 10, the above-mentioned sensor immediately senses the change in the state of the materials and transmits this change to the main control module 20 in real time. After receiving the feedback information from the sensor, the module can timely update the material storage data and timely control the electromagnetic lock of the grid door and the counting LED light on the grid door to operate.

[0068] For example, in combination Figure 2 In one embodiment of the present invention, the electromagnetic lock includes an intrinsically safe electromagnetic lock A01, a lock catch A02 and a reset spring A03, and its structure is as follows: Figure 3 shown.

[0069] In order to facilitate the operation of the storage device 10 and the retrieval and storage of materials in the storage space 100 on the storage device 10, one or more control interfaces are correspondingly provided on one or more storage devices 10, and multiple controls are provided on one or more operation interfaces 103, so that the controls on one or more operation interfaces 103 can be operated to input instructions to one or more storage devices 10, so that the electronic lock on the storage space 100 is opened and closed, so that the materials in the storage space 100 can be retrieved or stored. In addition, through the operation interface 103, the staff can also query the material storage information, and display the specific storage location of the material through the operation interface 103, and provide retrieval guidance, so as to achieve fast and accurate positioning and optimize the material retrieval process.

[0070] It should also be noted that the operation interface 103 and its controls strictly comply with explosion-proof standards to ensure stable and safe operation in the flammable and explosive extreme environment of a mine.

[0071] In some optional implementations of this embodiment, the controls provided on the storage device 10 include touch buttons provided on the display screen or physical buttons provided on the display screen.

[0072] In some alternative implementation manners of this embodiment, the instructions input to the storage device 10 include direct or indirect input instructions, where: direct instructions include instructions that can be directly obtained by operating one or more controls. After operating or pressing a control once, the storage device 10 correspondingly executes an operation once. Indirect instructions include instructions that require cooperation with other input or output operations after operating the control. For example, after operating the control, additional instructions such as a password instruction, a fingerprint instruction, or a verification message need to be separately input, and then the storage device 10 executes the corresponding operation.

[0073] It should be noted that the above instructions and spaces are set according to actual needs. In this embodiment, they are only used as an optional manner for exemplary illustration and are not uniquely limited thereto.

[0074] In some alternative implementation manners of this embodiment, the reading and writing module 80 includes an RFID reader. In a mine intelligent working face material management device of the present invention, a unique number is assigned to each material, and an RFID tag containing key data such as the number and type is printed and pasted on the corresponding material, realizing the accurate correspondence between the material and the information. At the same time, in order to ensure clear responsibility for material management, each material is bound to a user, enabling the usage situation of the material to be traceable and the asset resume record to be maintained. All usage tracks of the materials can be queried. The RFID reader installed on the material cabinet communicates efficiently with the PLC through the human-machine interface, can accurately identify the type and quantity of the material, and enter the information into the system, realizing the intelligent allocation of the material to the designated grid. The RFID tag not only stores a large amount of information, but also the information can be updated and modified, providing technical support for automatically updating the material inventory quantity. At the same time, this information can be stored in the database in real time, ensuring the timeliness and accuracy of the data. Using the RFID reader, the system can quickly identify and inventory a large number of materials. Since the RFID technology allows multiple tags to be read simultaneously, the inventory efficiency is significantly improved. The inventory result can be updated to the system in real time, automatically correcting the inventory data, thereby ensuring the accuracy and timeliness of the data and further strengthening the material management ability of the device in the explosion-proof environment.

[0075] In order to facilitate further monitoring of the taking and placing of materials in the storage space 100 on the material storage device 10, one or more monitoring devices 70 are correspondingly provided on one or more storage devices 10. One or more monitoring devices 70 are correspondingly arranged outside the storage device 10, on the side where the storage space 100 is opened for taking and placing materials. The monitoring view of the monitoring device 70 can clearly capture the picture of the operation interface 103 and the picture of taking or placing materials, so that the action of taking or placing materials can be photographed through the monitoring device 70.

[0076] In some alternative implementation manners of this embodiment, the monitoring device 70 includes a monitoring camera and its corresponding and supporting devices or equipment. Preferably, it is a intrinsically safe high-definition mine camera. This camera not only has the technologies of fog penetration imaging and intelligent zoom, ensuring stable operation in extremely harsh mine environments such as high humidity, high temperature, and high dust, but also is designed in strict accordance with explosion-proof standards and has excellent waterproof and dust-proof characteristics. This camera can monitor the area around the material cabinet in real time. Once it detects that a person approaches or performs a specific operation, it will be immediately activated to capture clear portrait pictures. By using image recognition algorithms, on the premise of explosion-proof safety, the captured pictures can be efficiently processed and analyzed to ensure that the material cabinet can accurately identify and record the personnel information of the retrieved materials. This design not only greatly enhances the safety and accuracy of material management, but also provides support for subsequent intelligent management and traceability of underground materials, realizing efficient, safe, and intelligent management in an explosion-proof environment.

[0077] Specifically, in the intelligent mine working face material management device of the present invention, the main control module 20 includes: an image processing module 202, a data processing module 201, and a communication module 200, where:

[0078] An image recognition algorithm or an image recognition module is provided in the image processing module 202. The image processing module 202 is connected to the monitoring device 70. A variety of preset actions for taking or storing materials in the storage space 100 on the storage device 10 are pre-stored in the image processing module 202. After the monitoring device 70 monitors an action of taking or storing materials, the image processing module 202 calls the image recognition algorithm or the image recognition module to compare with the pre-stored preset actions; the data processing module 201 is connected to the reading and writing module 80, the image processing module 202, the gravity detection device 101 and the counting device 102 in each storage space 100. A memory 2010 is carried or integrated on the data processing module 201. The maximum storage threshold and the minimum storage threshold of the weight and quantity of materials in each storage space 100 input externally are stored in the memory 2010. The data processing module 201 is used to transfer the information of taking or storing materials in the storage space 100 read by the reading and writing module 80 to the memory 2010 for processing. After the gravity detection device 101 and the counting device 102 detect the material data in each storage space 100, the data processing module 201 will call the maximum storage threshold and the minimum storage threshold in the memory 2010 to compare with the detected data. When the comparison result is equal to the maximum storage threshold, the data processing module 201 controls the external speaker 90 to issue a voice or video reminder, and no longer adds materials to the storage space 100 equal to the maximum storage threshold. When the comparison result is less than or equal to the minimum storage threshold, a voice or video reminder is issued to replenish the materials in the storage space 100 less than or equal to the minimum storage threshold to the corresponding maximum storage threshold. At the same time, the data processing module 201 is used to receive the comparison result of the image processing module 202, perform selective alarm according to different comparison results, and generate log information or a list including material storage, taking and alarm; the communication module 200 is connected to the data processing module 201 and the server 30, and is used to establish a communication connection for external devices connected to the data processing module 201.

[0079] In some alternative implementation manners of this embodiment, after the reading and writing module 80 reads the information of taking or storing materials in the storage space 100 and transfers it to the memory 2010 for processing, it includes data recording and storage.

[0080] As some alternative implementation manners of this embodiment, the alarm is implemented through the speaker 90. The speaker 90 is arranged on the storage device 10, and the storage device 10 is connected to the main control module 20. The speaker 90 alarms according to the data or alarm instructions transmitted by the main control module 20. The above alarm mechanism includes:

[0081] When specific events occur in the material cabinet, such as key operations like material retrieval and abnormal status, the system will immediately generate clear and accurate voice prompt messages and play them through these explosion-proof certified audio output devices. This method ensures that even in the special environment of a mine full of potentially explosive gases, workers do not need to directly view the display screen or operation interface 103 of the material cabinet, and can quickly understand the real-time status and relevant information of the material cabinet just by the voice prompts. In addition, this explosion-proof and intelligent voice interaction method not only improves the convenience and efficiency of material management, but also maximally guarantees the safety and reliability of mine operations. At the same time, this alarm mechanism also has a high degree of sensitivity, can comprehensively monitor and immediately respond to various potential risk events including the grid door not being properly closed and abnormal material quantities, effectively preventing explosion hazards caused by electrical sparks or mechanical failures. Any automatic detection of abnormal situations will immediately trigger the corresponding explosion-proof alarm signal and quickly convey it to the management personnel through multiple channels such as sound and light, text messages, etc., to ensure that the alarm information can be received in the first time for timely and effective handling and intervention. When the material quantity drops below the preset safety inventory level, the system will immediately activate the automatic alarm or reminder function. This feature not only prevents production delays caused by inventory shortages, but also greatly reduces the potential safety risks caused by insufficient materials. In addition, the monitoring ability of this comprehensive alarm mechanism covers all key operations such as requisition, return, inbound and outbound, etc., can accurately identify abnormal operations such as excessive requisition or unauthorized access, etc., and issue an alarm immediately when these events are detected. To ensure that the management personnel can quickly receive the alarm and take countermeasures, the system also has the function of remotely locking the cargo space to prevent further abnormal operations.

[0082] In order to improve the service life of the speaker 90 and ensure accurate and reliable alarm, the above-mentioned speaker 90 is set as an explosion-proof speaker 90.

[0083] In addition, in a mine-used intelligent working face material management device of the present invention, it further includes a management terminal 40. The management terminal 40 is connected to the data processing module 201 and the server 30, and is used for receiving the log information or list generated by the data processing module 201, and can control the data processing module 201 to remind the operator to replenish materials in different ways for multiple storage spaces 100 in one or more storage devices 10 according to the log information or list.

[0084] Specifically, the log information or inventory includes, but is not limited to, the type of materials, quantity, identity information of relevant operators, and precise time, etc. In addition, explosion-proof log recording points are set at each key operation node, such as the receipt and return of materials, and the inbound and outbound of inventory. Whenever these operations occur, the main control system will immediately activate the explosion-proof safety mechanism and automatically record detailed operation data, covering operation time, executor, operation type, types and quantities of materials or tools involved, and operation results, etc. All records are processed by explosion-proof encryption technology to ensure the security and integrity of the data and ensure the stability and safety of operation in a potentially explosive gas environment.

[0085] In some alternative implementation manners of this embodiment, the recorded logs are stored in a local or remote explosion-proof database in a predefined format (such as JSON, XML, etc.) to ensure the traceability and security of the data. To facilitate the query and management of log information by management personnel, the system also provides an explosion-proof secure log query interface or API interface, allowing management personnel to quickly retrieve the required logs according to specific query conditions (such as time range, operator, operation type, etc.). In addition, the system supports exporting the query results to various common file formats, such as Excel, CSV, PDF, etc., and the entire export process also complies with explosion-proof safety specifications to ensure the accuracy and security of the data and provide support for subsequent analysis and report compilation.

[0086] In addition, in a mine intelligent working face material management device of the present invention, a remote terminal 50 is further included. The remote terminal 50 is connected to the management terminal 40, the server 30, and the main control module 20. The remote terminal 50 can view the monitoring images of the monitoring device 70 and the log information or inventory generated by the data processing module 201 in real time, and can issue instructions to the storage space 100 on one or more storage devices 10 alone to control the opening and closing of the electronic lock of the storage space 100, or issue instructions to the management terminal 40 to open and close the electronic lock of the storage space 100 on one or more storage devices 10 through the management terminal 40.

[0087] In order to further ensure the safety of the mine intelligent working face material management device of the present invention, improve the storage and retrieval efficiency of materials, and prevent the loss and damage of materials, resulting in economic waste, the main control module 20 also supports system update and upgrade, and can be updated and upgraded automatically or by receiving external input update instructions, such as updating through update instructions or update data input by the remote terminal 50 or the management terminal 40, so as to realize the all-round management of materials, improve the safety, stability, and explosion-proof performance of the storage device operation, and ensure the safety of operators in the coal mine operation environment.

[0088] As an example, to ensure the security of updates and upgrades, multiple authentication methods are set during the update and upgrade process, including but not limited to password locks. These methods have all passed explosion-proof safety certifications to ensure that only authorized users can access the stored materials in a safe explosion-proof environment. In terms of system security, user passwords are stored in encrypted form, and advanced encryption technologies such as hash algorithms are used to protect user credentials from unauthorized access. In addition, to prevent brute-force attacks, the system of this device specifically sets an upper limit on the number of login attempts, and this function performs excellently in explosion-proof tests, ensuring stable operation even in extreme environments. If the number of consecutive incorrect inputs exceeds the predetermined number, the system will temporarily lock the relevant account, thus greatly increasing the security of the account. The system also defines the operation scope according to user roles to achieve fine-grained access control. The administrator role is given broader settings and management permissions to effectively maintain the operation and security of the material cabinet in an explosion-proof environment. This role-based access control method not only ensures that different users obtain appropriate permissions according to their responsibilities but also helps to effectively prevent potential security threats on the premise of explosion-proof safety.

[0089] As another example, it is also possible to achieve remote, safe, and reliable monitoring and management of the intelligent electronic material cabinet. Whether it is an inbound or outbound operation, through the explosion-proof safety-reinforced remote terminal 50, important information such as the operation status and inventory situation can be viewed and monitored in real time. All data transmissions are encrypted to ensure the secure transmission of information in a potentially explosive environment. By logging in to the system, the login situation and operation records can be viewed and tracked in real time. Once any abnormal operation or potential risk is detected, the main control system will immediately trigger the explosion-proof alarm mechanism to ensure that the management personnel can respond and handle it quickly. In addition, to further improve the security of the storage device 10, the management personnel can also conveniently maintain and manage the intelligent electronic cabinet through the network, such as modifying user permissions, resetting passwords, etc. All operations are carried out within the explosion-proof safety framework, effectively preventing potential safety hazards caused by misoperations or malicious attacks.

[0090] To enable the mine intelligent working face material management device of the present invention to work and operate safely and stably in the coal mining environment, the circuits of all modules and devices of the present invention are set to be intrinsically safe, that is, intrinsically safe circuits. This makes it so that whether the circuit and the modules it is connected to are in a normal working state or facing a specified fault state, the electric sparks and thermal effects generated by the circuit are strictly controlled within a safe range and can never ignite any specified explosive mixture. Thereby, it can be ensured that the set circuits meet the explosion-proof requirements of the coal mine environment, and the energy level of the circuit is limited to an extremely low state, thus fundamentally ensuring the absolute safety of the device in a potentially explosive environment such as underground.

[0091] To further ensure the safety of the mine intelligent working face material management device of the present invention, the coal mine operation environment, the safety of the operators, and the materials stored in the storage device, the electrical clearances of the above-mentioned various modules, devices, and equipment are designed in strict compliance with the explosion-proof standard of GB7251.1 (Low-voltage switchgear and controlgear). The electrical clearances are increased to effectively prevent the occurrence of arc discharge or breakdown phenomena, ensuring underground safety. All devices, equipment, and modules comply with national standards and specifications, and all electrical components comply with the safety use standards for coal mines underground. At the same time, for the dust and moisture underground, the creepage distance (i.e., the shortest distance measured along the insulation surface) is increased as the pollution level rises, ensuring the excellent explosion-proof performance of the device.

[0092] The usage process of a mine intelligent working face material management of the present invention includes:

[0093] In the operation process of the mine intelligent working face material management device, the operator first activates the device through biometric technology (such as face recognition or fingerprint recognition) or password input. After the system is activated, the equipped intrinsically safe mine camera immediately starts to conduct full-round video monitoring to capture the entire operation process. If any abnormality occurs during the system startup or operation process, the alarm mechanism will be triggered, and the speaker 90 will emit an alarm to prompt the operator.

[0094] During the material storage stage, the operator needs to first scan the RFID tags of all materials to be stored. The RFID reader embedded in the cabinet then reads the exclusive information of each material, including the type, name, number, and quantity of the material, etc. These information will be recorded and displayed on the touch display screen. After the data processing module 201 of the intrinsically safe PLC (Programmable Logic Controller) receives the information transmitted by the RFID reader, it controls the electromagnetic lock of the storage bin corresponding to the material type to open. Once the material is placed in the storage bin, the built-in gravity sensor immediately senses the weight change of the material and transmits the monitoring signal back to the PLC data processing module 201. This module compares the sensed weight with the preset maximum weight threshold. If the detected weight does not exceed the standard, storage is allowed; if it exceeds, the speaker 90 is triggered to emit a voice prompt, informing that the storage bin is full and no new materials can be added. As new materials are put in, the counting sensor correspondingly senses the quantity change and transmits the new quantity data to the data processing module 201. This module then issues an instruction to the counting LED to update the displayed value to reflect the latest status. At the same time, the data processing module 201 records the detailed information of the entire material storage in the internal memory 2010 and transmits it to the management terminal 40 in real time through the communication module 200, automatically generating an access audit log for subsequent auditing and monitoring.

[0095] The operator inputs the name or RFID number of the material to be retrieved and sets the retrieval quantity through the touch interface. Based on these inputs, the electromagnetic lock of the corresponding storage bin will open, allowing the material to be taken away. After the counting sensor senses that the material has been taken away, it triggers the counting LED indicator to display a new value. At the same time, the data processing module 201 records this information and updates it to each terminal device in real time through the network, ensuring that each retrieval of materials is accurately recorded, automatically generating an access audit log, enhancing the traceability and transparency of material management, and ensuring the efficiency, safety, and compliance with audit requirements of mine material management.

[0096] In order to further improve the storage and retrieval efficiency of materials and make the retrieval and storage of materials more flexible, it is also possible to set the opening and closing of the electronic lock of the storage space 100 on the storage device 10 through the user terminal 60. The user terminal 60 is connected to the server 30 and the main control module 20 to realize the retrieval and storage of materials.

[0097] In summary, an intelligent mining face material management device of the present invention overcomes the problems existing in traditional mining material management technologies, realizes the intelligentization, precision, and safety of mining face material management, and more importantly, ensures safe and stable operation in an explosive gas or dust environment. The device is specially designed for the complex and potentially dangerous underground working environment, integrating advanced intelligent voice technology and image recognition technology. It not only realizes voice prompts and camera portrait capture functions, but also significantly improves the safety and reliability of face material management through precise explosion-proof structure and material selection. Through careful explosion-proof planning and design of the internal structure of the material cabinet, combined with an intelligent material identification and management system, the device not only provides a user-friendly interaction interface, but also realizes the function of storing scattered materials in compartments, ensuring the safe storage and efficient management of materials in an explosion-proof environment. The introduction of the automatic inventory checking function makes the monitoring of material quantities automatic and explosion-proof safe. The intelligent inbound and outbound control further improves the efficiency and accuracy of material management, while greatly reducing the risk of human errors and loopholes. In addition, this intelligent management method not only optimizes material distribution and scheduling, reduces inventory costs, but also enhances the explosion-proof safety and convenience of the intelligent material management device in the underground coal mine face by implementing an account password login mechanism without a key. In terms of the control and management of the quantity of materials received, the system provides an efficient control mechanism and precise management method, ensuring the rationality and economic efficiency of material use, avoiding affecting the normal safety production of the underground working face due to material shortages, and also saving maintenance time. More importantly, the system can communicate with the ground material management system in real time through the underground ring network. When critical materials reach the safety inventory, it notifies the ground procurement department in a timely manner for replenishment, thereby further enhancing the explosion-proof safety and economic efficiency of material management. The automatically generated storage audit log and the convenient system export function provide convenience for operation monitoring and auditing by managers, ensuring the compliance and explosion-proof safety of operations. The exported log data also supports subsequent data analysis and report generation, assisting coal mining enterprises in making more informed decisions. The system also reserves platform interfaces and supports background version customization to meet the personalized explosion-proof requirements of various underground coal mine faces, providing a more flexible and customized solution. Continuous version updates and technical support ensure the stability and explosion-proof safety of the system, providing miners with a better and safer user experience.

[0098] In some optional implementation manners of this embodiment, in order to be able to further accurately detect subtle changes in the electrical or circuit state of the face material management device provided in an embodiment of the present invention, a plurality of sensors are also provided. Through the plurality of sensors provided, corresponding circuit data can be detected, and the on / off status of the circuit and other conditions can be judged according to the detected data.

[0099] Exemplarily, for example, the sensors provided include Hall current sensors, voltage transformers, temperature sensors based on the principle of thermal effect, photoelectric sensors, etc., and they are correspondingly connected to the load or power supply in the circuit, the measured circuit components, the analog input ports of the control system (such as single-chip microcomputers, PLCs, etc.), and the positions near the photosensitive elements or at the circuit nodes in a series-connected or parallel-connected manner, and the detected data is transmitted to the data processing module 201 for data processing such as comparison to determine the operating state of the circuit.

[0100] Considering wiring and maintenance factors, the installation position of the sensor should take into account the convenience of wiring with other devices, avoiding overly long or complex connections between the sensor and the control system to reduce signal interference and transmission loss. At the same time, the sensor should be installed in a position that is convenient for inspection and replacement. In some large electrical equipment, the sensor is usually installed near the inspection window of the equipment or in an easily accessible area so that maintenance and replacement can be carried out in a timely manner when the sensor fails.

[0101] It can be understood that all the above-mentioned sensors and their corresponding devices or components are existing and directly available products, which can be directly selected and used as needed during the use process.

[0102] In a second aspect, as Figure 5 shown, the present invention also provides a method for intelligent management of mining face materials, and the method includes:

[0103] Storing materials in multiple storage spaces 100 and correspondingly setting multiple electronic locks on the multiple storage spaces 100;

[0104] Configuring a control or device for controlling the opening and closing of the electronic lock;

[0105] Operating the space or device to open the electronic lock, taking or storing materials in the storage space 100, and giving an early warning when the taking or storing of materials in the storage space 100 is abnormal;

[0106] Detecting the quantity of materials in each storage space 100 to obtain the storage data of materials in each storage space 100;

[0107] Comparing the obtained material storage data with the preset maximum storage threshold and minimum storage threshold for each storage space 100;

[0108] If the obtained comparison result is less than or equal to the minimum storage threshold, a voice or video reminder is given, and at the same time, the storage space 100 with a comparison result less than or equal to the minimum storage threshold is replenished with materials to the corresponding maximum storage threshold. If the obtained comparison result is equal to the maximum storage threshold, a voice or video reminder is given.

[0109] When managing materials using the above method, the above equipment can be used for implementation. In this way, accurate management of materials can be achieved, waste and damage of materials can be avoided, and the safety of the working environment and workers can be ensured.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
