Description

Technical Field

[0001] This application relates to the field of warehouse management technology, and in particular to an emergency material control circuit and an emergency material control system. Background Technology

[0002] The management effectiveness of emergency supplies warehouses directly affects the speed of emergency response and the efficiency of resource allocation in emergencies such as natural disasters and public health events. An ideal emergency supplies management system needs to achieve automated registration of supplies entering and leaving the warehouse, real-time monitoring of inventory status, and precise traceability throughout the entire circulation chain, thereby providing timely and accurate data support for command and decision-making.

[0003] However, the existing emergency warehouse management of controlled materials generally adopts a combination of manual registration and periodic inventory checks, which has significant technical shortcomings. First, regarding information updates, changes in the status of controlled materials rely on manual system entry, leading to a time lag between inventory data and actual conditions. This can create an information vacuum of 30 minutes to 2 hours during emergencies, severely impacting decision-making efficiency. Second, regarding status awareness, existing systems cannot monitor the dynamic usage of controlled materials and key indicators such as equipment availability in real time. Statistics show that approximately 68% of emergency warehouses cannot accurately provide a real-time list of available controlled materials during disasters. Finally, regarding traceability, paper or discrete electronic records are insufficient to form a complete chain of controlled material circulation. When controlled materials are lost or damaged, it takes an average of 4 to 8 hours to complete the responsibility tracing, failing to meet the urgent requirements of emergency response.

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0027] It should be noted that the management effectiveness of emergency supplies warehouses directly affects the speed of emergency response and the efficiency of resource allocation in emergencies such as natural disasters and public health events. An ideal emergency supplies management system needs to achieve automated registration of supplies entering and leaving the warehouse, real-time monitoring of inventory status, and precise traceability of the entire circulation chain, thereby providing timely and accurate data support for command and decision-making.

[0028] However, the existing emergency warehouse management of controlled materials generally adopts a combination of manual registration and periodic inventory checks, which has significant technical shortcomings. First, regarding information updates, changes in the status of controlled materials rely on manual system entry, leading to a time lag between inventory data and actual conditions. This can create an information vacuum of 30 minutes to 2 hours during emergencies, severely impacting decision-making efficiency. Second, regarding status awareness, existing systems cannot monitor the dynamic usage of controlled materials and key indicators such as equipment availability in real time. Statistics show that approximately 68% of emergency warehouses cannot accurately provide a real-time list of available controlled materials during disasters. Finally, regarding traceability, paper or discrete electronic records are insufficient to form a complete chain of controlled material circulation. When controlled materials are lost or damaged, it takes an average of 4 to 8 hours to complete the responsibility tracing, failing to meet the urgent requirements of emergency response.

[0029] Therefore, how to build an emergency warehouse material management system that can achieve fully automated real-time monitoring and solve the problems of information lag, lack of status awareness and difficulty in traceability is an urgent problem to be solved.

[0030] To address the aforementioned technical issues, this embodiment proposes an emergency supplies management circuit. By incorporating this circuit into the emergency supplies management system, the identification module 1 first acquires the identification information on the supplies to be managed when they pass through the material detection channel. Then, the direction detection module 2 detects the direction of movement of the supplies within the detection channel. Subsequently, the control module 3 updates the inventory status of the corresponding supplies in real time based on the identification information and direction of movement, and generates management instructions based on the inventory status. Finally, the execution module 4 manages the supplies according to the management instructions. Compared to existing methods, this embodiment achieves full-process management of emergency supplies from entry / exit to inventory management by constructing a closed-loop real-time management chain of identification, judgment, decision-making, and execution.

[0031] For ease of understanding, the following is combined with Figures 1 to 3 The emergency supplies management circuit provided in the embodiments of this application will be described in detail.

[0032] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the emergency material management circuit proposed in this application.

[0033] like Figure 1 As shown, in this embodiment, the circuit includes: a recognition module 1, a direction detection module 2, a control module 3, and an execution module 4; The output of the recognition module 1 and the output of the direction detection module 2 are respectively connected to the input of the control module 3, and the output of the control module 3 is connected to the input of the execution module 4. The identification module 1 is used to acquire the identification information on the materials to be controlled when the materials to be controlled pass through the material detection channel; The direction detection module 2 is used to detect the movement direction of the controlled material in the controlled material detection channel; The control module 3 is used to update the inventory status of the corresponding controlled materials in real time according to the identification information and the direction of movement, and generate control instructions based on the inventory status. The execution module 4 is used to manage the materials to be managed in accordance with the management instructions.

[0034] It should be noted that the aforementioned identification module 1 can be any module capable of automatically acquiring material identification information, such as a radio frequency identification (RFID) reader / writer module, a QR code scanner module, or a Bluetooth beacon receiver module. The aforementioned direction detection module 2 can be any module capable of detecting the direction of object movement and determining whether materials are entering (inbound) or leaving (outbound). For example, a through-beam infrared photoelectric sensor module, a microwave radar sensor module, or a laser rangefinder sensor array module. The aforementioned control module 3 can be any module capable of data processing and decision-making, integrating information from the identification and direction detection modules 2 for logical operations, and outputting control commands. For example, an embedded ARM microcontroller (such as an NXP i.MX RT1170), an industrial-grade PLC (programmable logic controller), or a server motherboard. The aforementioned execution module 4 can be any module capable of receiving electrical signal commands and driving external devices to perform physical actions, such as a relay driver module, a serial communication module (such as RS-485), or a wireless communication module (such as a 4G / 5G module).

[0035] It should also be noted that the aforementioned identification information can be a digital code or data set that distinguishes and identifies different of the aforementioned controlled materials. Understandably, the aforementioned identification information is stored in an electronic tag attached to the material, serving as an electronic identification card for the material within the management system. The aforementioned direction of movement can be the spatial orientation of the controlled material as it passes through the material detection channel formed by the warehouse entrance and exit. Understandably, the aforementioned direction of movement is used to determine whether the controlled material's circulation status is inbound or outbound. The aforementioned inventory status can be a dynamically updated data set reflecting the real-time status of a specific controlled material in the warehouse. The aforementioned control instructions can be digital commands with clear operational guidance automatically generated by the control module 3 based on real-time analysis of the latest inventory status.

[0036] In the specific implementation, when the aforementioned controlled materials (such as rescue tents) affixed with RFID tags pass through the material detection channel at the warehouse entrance, the identification module 1 emits a radio frequency signal and receives the signal reflected back from the tag. After capturing this radio frequency signal, the identification module decodes it to uniquely obtain the identification information representing the tent (such as the material code "TENT-001"), and sends this identification information to the control module 3. The direction detection module 2 is arranged near the identification module 1, together forming the material detection channel. Assuming three sets of infrared sensors are arranged from top to bottom, when a controlled material enters the warehouse, it will sequentially block the higher-height sensor, the medium-height sensor, and finally the lower-height sensor; when leaving the warehouse, the blocking order is reversed. The direction detection module 2 analyzes the sequence of these sensing signals in real time, and by judging the order in which the sensors are triggered, it accurately determines whether the material is moving into or out of the warehouse, and sends this direction of movement to the control module 3. The control module 3 receives the identification information (TENT-001) from the identification module 1 and the movement direction (inbound) from the direction detection module 2. The control module 3 first queries its internal database to check the current inventory status of the materials corresponding to the identification information. Assuming the current inventory is 5 tents, and considering the inbound direction, the control module 3 performs a real-time update, increasing the inventory by 1 tent to 6 tents. Subsequently, the control module 3 generates the control instruction based on this inventory status. For example, the system's preset rule is to generate a replenishment instruction when the tent inventory is below 10 tents. After the update, the inventory is 6 tents, below the threshold, so the control module 3 generates a replenishment instruction as the control instruction and outputs it to the execution module 4. The execution module 4 receives the control instruction (replenishment instruction) from the control module 3. Depending on the instruction type, the execution module 4 drives different external devices. For example, the aforementioned execution module 4 can close a switch via a relay circuit to illuminate the out-of-stock warning indicator light in the warehouse; or, through the wireless communication module (such as SIM800) integrated into the aforementioned execution module 4, it can automatically send a text message to the purchasing administrator's mobile phone, stating: "Emergency tent inventory (6 tents) is insufficient; please replenish stock promptly." This completes the closed-loop operation of managing the aforementioned materials according to the control instructions.

[0037] Furthermore, in order to obtain the identification information on the aforementioned materials to be controlled, continue as follows: Figure 1 As shown, in this embodiment, the identification module 1 includes: a radio frequency identification unit 11 and a signal processing unit 5212; The output terminal of the radio frequency identification unit 11 is connected to the input terminal of the signal processing unit 5212, and the output terminal of the signal processing unit 5212 is connected to the input terminal of the control module 3. The radio frequency identification unit 11 is used to acquire the radio frequency signal of the material to be controlled when the material to be controlled passes through the material detection channel; The signal processing unit 5212 is used to decode the radio frequency signal to obtain the identification information and send the identification information to the control module 3.

[0038] It should be noted that the aforementioned RFID unit 11 can be any unit capable of activating RFID tags and receiving the raw RFID signals reflected back from the tags. For example, it can be composed of an RFID reader chip (such as Impinj R2000 or ST25RU3993), an RFID antenna (such as a Laird Connectivity A9028 circularly polarized antenna or a Taoglas AFX antenna), and an impedance matching circuit. The aforementioned signal processing unit 5212 can be any unit capable of demodulating, decoding, and verifying the raw RFID signals transmitted from the RFID unit 11 that cannot be directly understood by the control module 3, converting them into standard digital information. For example, it can be a dedicated digital signal processor (DSP), a processing core integrated into the reader chip, or a microcontroller (such as an ARM Cortex-M series MCU).

[0039] It should also be noted that the aforementioned radio frequency signal can be the physical carrier for communication between the aforementioned radio frequency identification unit 11 and the RFID tag attached to the aforementioned controlled material, and its frequency is usually located in the radio frequency band. For example, the aforementioned radio frequency signal can be an ultra-high frequency (UHF) electromagnetic wave conforming to the ISO / IEC 18000-6C standard, with a typical operating frequency range of 860MHz to 960MHz, or it can be a high frequency (HF) electromagnetic wave, with a typical frequency of 13.56MHz.

[0040] In its implementation, when the controlled materials affixed with RFID tags pass through the material detection channel, the radio frequency identification unit 11 begins to operate. Its antenna (e.g., a Laird A9028 antenna), driven by a reader chip (e.g., an Impinj R2000), transmits radio frequency electromagnetic waves of a specific frequency (e.g., 860MHz-960MHz) into the channel area. This electromagnetic wave energy activates the RFID tags entering their effective area. The tags, through backscatter modulation technology, load their internally stored unique encoded information into the reflected echo. After receiving this weak reflected signal, the antenna of the radio frequency identification unit 11 amplifies it initially via an internal low-noise amplifier, forming the radio frequency signal, which is then output to the signal processing unit 5212. The signal processing unit 5212 then demodulates the radio frequency signal, extracts the carrier wave, and uses its internally embedded decoding algorithm to identify the digital bit stream composed of 0s and 1s, ultimately reconstructing the identification information (e.g., a 96-bit EPC code) of the emergency medical supplies. Subsequently, the signal processing unit 5212 sends the decoded identification information to the control module 3 in a standard data format to complete a complete automatic identification process for materials.

[0041] Furthermore, in order to obtain the aforementioned radio frequency signals, the following steps are continued... Figure 1 As shown, in this embodiment, the radio frequency identification unit 11 includes: an antenna array 111 and a signal amplifier 112; The antenna array 111 is connected to the input terminal of the signal amplifier 112, and the output terminal of the signal amplifier 112 is connected to the input terminal of the signal processing unit 5212.

[0042] It should be noted that the antenna array 111 described above can be a collection of multiple independent antenna elements arranged in a specific spatial structure for transmitting and receiving radio frequency signals. For example, it can be composed of multiple narrow-beam planar antennas (e.g., Laird Connectivity A9028), dipole antennas (e.g., Taoglas TFX series), or ceramic antennas. The signal amplifier 112 described above can be a low-noise amplifier, for example, a signal amplifier 112 of model number Analog Devices ADL5542 or Texas Instruments INA-023.

[0043] In its implementation, the antenna array 111 is strategically positioned at different locations within the material inspection channel (e.g., at installation heights of 0.6m and 1.2m, respectively) and tilted at a specific angle (e.g., 45 degrees) to form a three-dimensional reading area without dead zones. When an RFID tag attached to the material to be controlled enters this area, the radio frequency signal reflected back by the antenna array 111 is captured by one or more antenna elements in the array. Due to significant signal attenuation during spatial propagation, the captured original signal is extremely weak. This weak signal is then transmitted to the input of the signal amplifier 112. The signal amplifier 112 linearly amplifies the signal with its inherent gain (e.g., 20dB), significantly improving its voltage or power level while maintaining the integrity of the encoded information in the signal. The amplified and improved radio frequency signal is output to the input of the signal processing unit 5212, providing a reliable signal basis for the subsequent decoding process.

[0044] In this embodiment, an emergency supplies management circuit is set up in the emergency supplies management system. The identification module 1 in this circuit first acquires the identification information on the supplies to be managed when they pass through the supply detection channel. Then, the direction detection module 2 detects the direction of movement of the supplies in the detection channel. Afterwards, the control module 3 updates the inventory status of the corresponding supplies in real time based on the identification information and the direction of movement, and generates management instructions based on the inventory status. Finally, the execution module 4 manages the supplies according to the management instructions. Compared with existing systems, this embodiment achieves full-process management of emergency supplies from entry and exit to inventory management by constructing a closed-loop real-time management chain of identification, judgment, decision-making, and execution.

[0045] Reference Figure 2 , Figure 2 This is a schematic diagram of the second embodiment of the emergency material management circuit proposed in this application.

[0046] Based on the above embodiments, a second embodiment of this application is proposed. In order to detect the movement direction of the controlled material in the controlled material detection channel, such as... Figure 2 As shown, in this embodiment, the direction detection module 2 includes: an infrared sensing unit 21 and a direction determination unit 22; The output terminal of the infrared sensing unit 21 is connected to the input terminal of the direction determination unit 22, and the output terminal of the direction determination unit 22 is connected to the input terminal of the control module 3. The infrared sensing unit 21 is used to transmit the generated sensing signal to the direction determination unit 22 when it senses that the material to be controlled is passing through the material to be controlled detection channel. The direction determination unit 22 is used to determine the movement direction of the controlled material in the controlled material detection channel according to the sequence of the sensing signals, and send the movement direction to the control module 3.

[0047] It should be noted that the aforementioned infrared sensing unit 21 can be any unit capable of detecting whether materials are passing through the detection channel by emitting and receiving infrared light. In specific implementations, it can be, for example, composed of a through-beam photoelectric sensor (e.g., Telco T18 series or Sick WTB4S-3P2231), a reflector-type photoelectric sensor, or an infrared light curtain sensor. The aforementioned direction determination unit 22 can be any unit capable of receiving and analyzing multiple sensing signals transmitted from the infrared sensing unit 21, and determining the direction of material movement by judging the timing sequence of these signals being triggered. For example, it can be a programmable logic device (such as a CPLD), a microcontroller (MCU) (e.g., STMicroelectronics STM32F103), or a dedicated digital logic chip.

[0048] Understandably, the aforementioned sensing signal can be an electrical signal generated by the infrared sensing unit 21 when it detects the controlled material passing through its monitoring area, representing the occurrence of the physical event. The sensing signal can be a direct electrical manifestation of the infrared beam being blocked or its reflection state changing. It should also be noted that the sensing signal can be a TTL low-level signal (e.g., dropping from 5V to 0V) generated by the receiver of a through-beam infrared sensor when the beam is blocked, an analog voltage signal output by a reflective sensor (whose amplitude varies with the detection distance), or a digital pulse signal shaped by a built-in comparator.

[0049] In its implementation, the infrared sensing unit 21 employs a through-beam photoelectric sensor array, with multiple sensor arrays at different heights arranged on both sides of the warehouse entrance and exit to form a seamless detection plane. When the controlled materials pass through the detection channel, they sequentially block the infrared beam emitted by the infrared transmitter and received by the receiver on the opposite side. Each pair of infrared sensors generates a digital level transition when the beam is blocked, forming the aforementioned sensing signal and transmitting it to the direction determination unit 22. The direction determination unit 22 internally incorporates direction determination logic, continuously monitoring the signal status of all sensors. For example, suppose three sets of sensors, A, B, and C, are arranged on the channel. When the controlled materials enter the warehouse from the outside (inbound), sensor A is blocked first, then sensor B, and finally sensor C; the order is reversed when exiting. The direction determination unit 22 analyzes the sequence of these sensing signals through precise timestamp recording or state machine logic to accurately determine whether the movement direction is inbound or outbound, and sends this determination result as movement direction information to the control module 3.

[0050] Furthermore, in order to synchronize the above inventory status, continue as follows Figure 2 As shown, in this embodiment, the circuit further includes: an inventory module 5; The input terminal of the inventory module 5 is connected to the output terminal of the identification module 1, and the output terminal of the inventory module 5 is connected to the input terminal of the control module 3. The inventory module 5 is used to read the identification information and process the identification information to obtain inventory data; The inventory module 5 is also used to transmit the inventory data to the control module 3 to synchronize the inventory status.

[0051] It should be noted that the aforementioned inventory module 5 can be a module that can actively read material identification information and complete preliminary data processing and uploading in non-fixed channel scenarios (such as warehouse internal shelf areas). For example, it can be integrated into industrial-grade PDAs (personal digital assistants), handheld RFID readers (such as Zebra MC3330xR or Feig OBID i-scanID ISC.ANT.U430 / 470), or customized handheld terminal devices.

[0052] Understandably, the aforementioned inventory data can be a structured data set with clear business semantics, formed by the inventory module performing additional processing and encapsulation on the original identification information it reads. It differs from a single material identification code; instead, it is a complete data package containing inventory context information, enabling the control module to perform inventory verification.

[0053] In its implementation, the inventory module 5 scans emergency supplies in the target area (such as one or more shelves), batch-reads the RFID tags attached to the supplies, and obtains the original list of identification information. Subsequently, the inventory module 5 processes this original identification information, including but not limited to: adding timestamps, adding operator IDs, adding the current inventory location information, and performing a preliminary comparison with the pre-stored inventory list from the previous period to mark newly added or removed supplies. After these processing steps, the original identification information is transformed into inventory data with business context, which can be directly used by the system. Finally, the inventory module 5 wirelessly transmits the generated inventory data to the control module 3. The control module 3 merges and verifies this data with the automatically recorded inbound and outbound flow data from fixed channels, ultimately synchronizing and updating the global inventory status, ensuring consistency between the system records and the actual warehouse inventory.

[0054] Furthermore, in order to process the aforementioned identification information, continue as follows: Figure 2As shown, in this embodiment, the inventory module 5 includes: a reading unit 51, a processing unit 52, and a synchronization unit 53; The reading unit 51 is connected to the identification module 1 and the processing unit 52 respectively, and is used to transmit the read identification information to the processing unit 52; The processing unit 52 is connected to the synchronization unit 53 and is used to process the identification information to obtain inventory data. The synchronization unit 53 is connected to the control module 3 and is used to transmit the inventory data to the control module 3 to synchronize the inventory status.

[0055] It should be noted that the aforementioned reading unit 51 can be any unit capable of acquiring material identification information at close range and in batches, such as an integrated UHF RFID read / write engine (e.g., a module based on the Impinj E710 reader chip), a handheld RFID antenna (e.g., the Zebra AN480 series), or a two-dimensional imager (e.g., the Zebra DS8178 scanning engine for reading QR codes). The aforementioned processing unit 52 can be any unit capable of processing, packaging, and format conversion of the raw data acquired by the aforementioned reading unit 51. For example, an ARM architecture application processor (e.g., Qualcomm Snapdragon 660), an industrial-grade microcontroller (e.g., NXP i.MX 8M Mini), or an x86 architecture embedded CPU. The aforementioned synchronization unit 53 can be any unit capable of establishing a stable data connection with the aforementioned control module 3 and transmitting the aforementioned inventory data. For example, a 4G / 5G communication module (e.g., Quectel EC25-E), a Wi-Fi module (e.g., a circuit based on ESP32-S3), or a wired Ethernet controller (e.g., Microchip LAN8720).

[0056] In its implementation, during inventory checks, the reading unit 51 transmits the aforementioned radio frequency signal to scan all emergency supply tags on a designated area (such as a shelf). When a tag (such as a generator identified as GEN-005) is detected, the reading unit 51 transmits the decoded raw identification information to the processing unit 52 via a UART or USB interface. The processing unit 52 then runs the inventory application to process this raw data: first, it appends a timestamp and GPS / manually entered storage location information; then, it compares this data with a pre-loaded inventory plan to generate structured inventory data containing information on the differences between the actual inventory list and the planned inventory list. Finally, when the synchronization unit 53 detects an available network (such as warehouse Wi-Fi or a mobile cellular network), it automatically establishes a TCP / IP connection and transmits the inventory data in JSON format to the control module 3. Upon receiving the data, the control module 3 parses it and synchronizes the inventory status accordingly, for example, updating the status of the GEN-005 generator in the system from "in stock" to "inventory checked," completing a full mobile inventory process.

[0057] Reference Figure 3 , Figure 3 This is a schematic diagram of the third embodiment of the emergency material management circuit proposed in this application.

[0058] Based on the above embodiments, a third embodiment of this application is proposed. To generate the above control instructions, such as... Figure 3 As shown, in this embodiment, the control module 3 includes: a status monitoring unit 31 and an instruction generation unit 32; The input terminal of the status monitoring unit 31 is connected to the output terminal of the recognition module 1 and the output terminal of the direction detection module 2, respectively, and the output terminal of the status monitoring unit 31 is connected to the input terminal of the instruction generation unit 32. The status monitoring unit 31 is used to update the inventory status of the corresponding materials to be managed in real time based on the identification information and the direction of movement. The instruction generation unit 32 is used to generate control instructions based on the inventory status.

[0059] It should be noted that the aforementioned status monitoring unit 31 can be any unit capable of dynamically maintaining a digital image reflecting the latest location and quantity of all emergency supplies. For example, it could be a dedicated status tracking logic running on a server CPU (such as an Intel Xeon E5 series), a high-performance microprocessor (such as an NXP i.MX 8M Plus), or an FPGA. The aforementioned instruction generation unit 32 can be any unit capable of automatically generating operational control commands based on the real-time data provided by the aforementioned status monitoring unit 31, through preset business rules and algorithms.

[0060] In its implementation, the aforementioned status monitoring unit 31 continuously monitors the identification information from the aforementioned identification module 1 and the movement direction from the aforementioned direction detection module 2 through its input terminal. It also updates the inventory status of the corresponding controlled materials in real time. Upon receiving this information, the status monitoring unit 31 immediately performs a search and update operation in its internal status database (which can be implemented based on Redis or a MySQL in-memory table). Specifically, it finds the corresponding record based on "TENT-009" and then decrements its inventory quantity field by 1 based on the outbound direction. The updated inventory status (e.g., quantity changes from 10 to 9, status is sufficient) is saved in the database in real time. Simultaneously, this latest status data is output to the input terminal of the aforementioned instruction generation unit 32. The instruction generation unit 32 has multiple pre-set business rules that immediately evaluate the input inventory status. For example, the rule base defines that when the inventory quantity of a certain material is lower than a safety threshold (e.g., 5 items), a replenishment instruction is generated. Since the current status shows that the number of tents is 9, which is higher than the threshold, no instruction will be triggered this time. If the number drops to 4, the instruction generation unit 32 will immediately generate a specific control instruction, the content of which may be {Instruction type: Replenishment reminder, Target material: TENT-009, Suggested quantity: 10}.

[0061] Furthermore, in order to trigger an audible and visual alarm or send a notification to the user terminal when the aforementioned inventory status does not meet the preset status threshold, the process continues as follows: Figure 3 As shown, in this embodiment, the circuit further includes: an early warning module 6; The input terminal of the early warning module 6 is connected to the output terminal of the control module 3, and the output terminal of the early warning module 6 is connected to the input terminal of the execution module 4. The early warning module 6 is used to generate an early warning instruction when the inventory status does not meet the preset status threshold. The execution module 4 is also used to trigger an audible and visual alarm or send a notification to the user terminal according to the warning instruction.

[0062] It should be noted that the aforementioned early warning module 6 can be any module capable of real-time analysis of the inventory status output by the control module 3 and proactively generating alarm signals when potential risks are identified. For example, it could be a dedicated early warning algorithm running on a microcontroller (such as the STMicroelectronics STM32F407), a programmable logic controller (PLC) (such as the alarm management function block in the Siemens S7-1500 series), or early warning service software running on a server (such as an industrial PC equipped with an Intel Xeon processor).

[0063] Understandably, the aforementioned warning instructions can be formatted alarm data packets, the contents of which clearly indicate the risk type, risk level, materials involved, and recommended measures. These are digital commands that drive the aforementioned execution module 4 to perform specific alarm operations.

[0064] It is also understandable that the aforementioned preset status thresholds can be a set of quantitative benchmark parameters pre-stored in the system to objectively determine whether the inventory status is in an abnormal or risky range. For example, the thresholds may differ significantly for emergency supplies of different critical levels: for life-saving supplies (such as first-aid medicines), the aforementioned preset status threshold for their inventory quantity may be set as the lower limit of safe stock (such as 20 boxes); while for general supplies (such as common tools), the aforementioned preset status threshold may be set as the economic order point (such as 50 pieces); in addition, the aforementioned preset status thresholds can also be set for the expiration date of the supplies, such as the remaining expiration date in days threshold (such as 30 days).

[0065] In its implementation, the aforementioned early warning module 6 continuously receives real-time inventory status data from the aforementioned control module 3. When the inventory status received by the early warning module 6 (e.g., current inventory of 3 tents, with 25 days remaining validity) is compared with the aforementioned preset threshold, if a situation is found where the threshold is not met (inventory 3 < threshold 5), the early warning module 6 immediately generates the aforementioned early warning instruction. For example, {Instruction type: Low inventory warning, Level: Emergency, Target material: TENT-005, Current quantity: 3, Safety threshold: 5, Timestamp: ...}. The aforementioned early warning instruction is sent to the execution module 4 through the output terminal. The execution module 4 executes preset physical actions according to the instruction content: if it is an emergency level, it may simultaneously trigger an audible and visual alarm (e.g., drive a Werma 412.010 audible and visual alarm) and send a notification to the user terminal (e.g., send the early warning information to the warehouse manager's mobile phone via an SMS gateway).

[0066] Furthermore, in order to display the aforementioned inventory status and control instructions, continue as follows: Figure 3 As shown, in this embodiment, the circuit further includes: a display module 7; The input terminal of the display module 7 is connected to the output terminal of the control module 3; The display module 7 is used to display the inventory status and the control instructions.

[0067] It should be noted that the above-mentioned display module 7 can be any module that has the function of converting the digital information (inventory status) and system decision results (control instructions) generated by the control module 3 that reflect the core status of the system into a visual graphical, text or symbol interface, such as an industrial-grade human-machine interface, an LCD screen or an LED display board.

[0068] In its implementation, the display module 7 continuously receives real-time data from the output of the control module 3 via its input. This data encapsulates the core information of the current system, namely the inventory status and the control instructions. The display module 7 internally runs graphics rendering software or firmware, which parses the received data stream and maps it onto a preset visualization template. For example, the inventory status data packet sent by the control module 3 contains the inventory quantity, location, and availability of all materials, along with a newly generated control instruction: "Generator GEN-005 is out of stock, please replenish." After receiving this data, the drive circuit of the display module 7 renders it using a graphics processor, ultimately displaying on the screen the "3D warehouse layout," "material distribution heatmap," and a prominent "early warning information dashboard" as described in the handover document. The dashboard clearly lists all pending instructions, including GEN-005. This allows control personnel to have a clear understanding of the overall warehouse status and urgent tasks simply by observing the display interface, without needing to consult complex data reports.

[0069] To achieve the above objectives, this application also proposes an emergency supplies management system, which includes the emergency supplies management circuit described above.

Therefore, the effects achieved by the emergency material management system in this embodiment can also refer to the above embodiments, and this embodiment will not elaborate on them further.
