Description

Technical Field

[0001] The present invention belongs to the technical field of logistics monitoring, and in particular relates to an intelligent monitoring system for preventing the replacement of transport materials based on Beidou positioning. Background Art

[0002] In the traditional material transportation anti-substitution monitoring technology, there are a series of key problems that need to be solved urgently. These problems seriously restrict the security guarantee capability during the transportation of highly sensitive materials (such as sealed sample inspection products and judicial evidence). The current technology mainly relies on single-dimensional monitoring methods, such as GPS positioning or basic electronic lock control, and fails to achieve real-time collaborative analysis between positioning data, lock status and multiple sensors (such as vibration, tilt, load, etc.). This fragmented data processing method makes it difficult for the system to distinguish between normal operations and malicious behaviors. For example, when abnormal parking occurs on remote roads and the electronic lock is illegally opened, it is impossible to accurately judge whether it is normal maintenance or potential substitution behavior based on positioning information alone, resulting in misjudgment or omission. At the same time, traditional passive means such as physical seals and label identification are not only easy to be replaced or destroyed, but also lack dynamic verification mechanisms, and cannot effectively ensure the integrity of material packaging; In addition, the existing technology also has obvious deficiencies in authority management. Traditional electronic lock control usually relies on fixed passwords or mechanical keys, does not deeply bind authority verification with operator identity (such as biometrics, dynamic tokens), and lacks the function of encrypting and storing operation records. This makes manual inspection records easy to forge, and Bluetooth communication instructions may be hijacked by illegal terminals, which in turn leads to a significantly increased risk of forging authorization signals by the switcher. Once a switch dispute occurs, it is difficult for the system to accurately trace the person responsible, further weakening the credibility of the system. However, the existing technology shows obvious lag in abnormal response. When faced with emergencies such as route deviation and lock damage, the system often relies on post-event manual verification and lacks real-time intervention capabilities. For example, when a package is detected to be opened abnormally during transportation, the system can only passively record the event, but cannot immediately trigger the remote locking of the electronic lock, data forensics, or multi-terminal alarm push, making it impossible to effectively block the replacement behavior; In addition, the lack of closed-loop verification of the entire process is also a major shortcoming of existing technologies. There is a lack of effective data connection between the loading, transportation and unloading links, and the operations in each stage are highly independent but weakly correlated. For example, after the sample is sealed during loading, if the packaging is changed during transportation but the original label is retained, the system will not be able to cross-validate through multi-source data (such as sudden changes in load, abnormal lock status, etc.), which may eventually lead to invalid detection results. Summary of the invention

[0003] 1. Technical issues to be resolved In order to overcome the problem that the existing technology mentioned in the background technology is difficult to meet the anti-substitution needs of highly sensitive material transportation due to serious data island phenomenon, lack of trustworthy mechanism for authority management, and excessive reliance on manual intervention for abnormal response, the present invention provides an intelligent monitoring system for anti-substitution of transportation materials based on Beidou positioning, which integrates Beidou high-precision positioning, multi-source sensor collaboration, authority closed-loop verification and intelligent real-time blocking functions, so as to comprehensively improve the safety and reliability of the material transportation process.

[0025] Preferably, the monitoring and management platform also performs an operation of AI comparison with a preset route based on Beidou positioning data.

[0026] Working principle: The intelligent monitoring system for preventing the exchange of transported materials of the present invention takes Beidou positioning as the core, combines the Internet of Things and intelligent lock control technology, and realizes dynamic tracking and active protection of the whole process of material transportation. The specific working process is as follows: Real-time positioning and data transmission The Beidou positioning module of the monitoring device continuously obtains the latitude and longitude coordinates, movement speed and timestamp of the materials, establishes a real-time connection with the cloud monitoring management platform through the 4G communication module, and actively uploads positioning data every 5 minutes. If an abnormality is detected, an event report is immediately triggered; The electronic lock module has a built-in conductive contact sheet and a steel wire rope closed circuit. When the lock body is cut or illegally pulled out, the circuit interruption triggers a hardware-level alarm signal. The control unit pushes the abnormal event to the platform within 0.5 seconds through the 4G module. Permission verification and smart lock control When a user initiates an unlocking request through the APP, he must first conduct dynamic key verification with the monitoring management platform. After confirming the operation authority, the APP sends an encrypted instruction to the electronic lock through the Bluetooth module; The driving component of the electronic lock adopts dual electromagnet collaborative control: when the first electromagnet is energized, it generates repulsive force to drive the lock core to separate (unlock), and when the second electromagnet is activated, it adsorbs the lock core to achieve locking. The insertion depth of the lock core is precisely controlled by the slide rail, and the tensile strength is more than 200N to prevent violent damage; Anomaly detection and automated response The system uses level detection technology to monitor the physical connection status of the electronic lock in real time. If the lock body is abnormally disconnected during transportation (such as being pried or cut), the control unit will immediately mark the event level, synchronously report the location information and freeze subsequent operation permissions; The monitoring and management platform can perform AI comparison with the preset route based on Beidou positioning data (trajectory data). If the material deviates from the path and exceeds the threshold, a three-level alarm strategy (SMS reminder → sound and light alarm → linkage with law enforcement platform) will be automatically triggered, without the need for manual intervention throughout the process. Full-link data closed loop From material loading to delivery, all operation logs (unlocking time, operator identity, geographic location) are encrypted and stored in the cloud, supporting backtracking by timestamp or event type to form an unalterable electronic evidence chain; The advantages of the present invention are: High-precision monitoring at all times and in all areas The Beidou positioning module achieves meter-level positioning accuracy and second-level time synchronization. Through blind spot positioning data storage and combined with 4G / Bluetooth dual-channel communication, the location information of remote areas with no signal blind spots can be uploaded normally. Multiple anti-vandalism designs The electronic lock adopts a dual insurance mechanism of electromagnetic drive + wire rope conductive circuit: the lock core structure can withstand 200N pulling force, and the circuit alarm will be triggered immediately when the wire rope is cut or the plug rod is pulled out, which greatly increases the difficulty of cracking compared to ordinary mechanical locks; Intelligent permission management Dynamic keys are linked to geographic fences. For example, only authorized personnel are allowed to unlock the warehouse within a 500-meter radius. Illegal requests will be automatically intercepted and recorded by the system to prevent the risk of collusion between internal and external parties to exchange materials. Automatic exception handling The system has a built-in three-level response mechanism (early warning → alarm → law enforcement linkage). The time from detecting an abnormality to starting the disposal process is less than 1 second, which is 90% more efficient than manual inspections. It is particularly suitable for the transportation of highly sensitive materials such as vaccines and military equipment. Low power consumption and high reliability The control unit adopts an event-driven working mode. It enters a dormant state when not working. The abnormal event wake-up response time is less than 50ms. It can still operate stably in extreme environments of -30℃~60℃, meeting the needs of cross-border long-distance transportation. Extended compatibility The system supports the access of peripherals such as temperature, humidity, and vibration sensors, and customizes alarm rules (such as excessive tilt and abnormal temperature) through the monitoring management platform to meet the diversified monitoring needs of special materials.

[0027] Example 1: Normal transportation process verification Technical implementation steps System Initialization A monitoring device is installed on the transport vehicle, the electronic lock module fixes the material box through a steel wire rope, and the conductive contact piece is connected to the closed circuit at the end of the plug rod; After the control unit is started, it automatically connects to the Beidou positioning module, initializes the 4G communication module parameters (presets the monitoring and management platform IP address), and the Bluetooth module enters the waiting for pairing state; Permission verification and locking operations The warehouse manager logs in to the account through the APP, scans the QR code of the electronic lock to bind the material information, and the monitoring management platform automatically generates a dynamic key and sends it to the APP; After loading is completed, the administrator clicks the "lock" button on the APP, the Bluetooth module receives the encrypted command, and the control unit activates the second electromagnet (56), driving the two core blocks (55) to insert into the core groove (32) of the lock core (31), thereby completing the locking; at this time, the tensile strength of the lock body reaches 200N, and the conductive loop of the steel wire rope is closed; Transport process monitoring The Beidou positioning module collects longitude and latitude coordinates (error ±1m) and moving speed every 30 seconds, and the 4G module packages the data and uploads it to the monitoring management platform every 5 minutes; When the transport vehicle enters the preset electronic fence (such as a highway section), the platform automatically compares the trajectory deviation rate to less than 1%, and the system determines it as normal transportation; Secure delivery and unlocking After arriving at the destination, the consignee's APP initiates an unlocking request, and the platform verifies its authority and confirms that the geographical location is within the preset fence (500 meters radius of the warehouse); After the control unit receives the command, the first electromagnet (53) is energized to generate a repulsive force, driving the core block (55) to disengage from the lock core slot (32). The unlocking takes 2.8 seconds, and the wire rope is detachable. The entire operation log (timestamp, operator ID, location) is encrypted and stored in the cloud. Technical effect verification Permission control: When an unauthorized person attempts to connect to the app through Bluetooth, the system triggers permission interception in step D, and the unlocking failure rate is 100%; Anti-destruction capability: When simulating the cutting of the wire rope, the conductive circuit is interrupted, triggering step S7 and an alarm. The platform receives the alarm information within 3 seconds; Positioning accuracy: Compared with ordinary GPS equipment, the Beidou positioning data deviation is ≤0.7m, which meets the transportation control requirements.

[0028] Example 2: Abnormal event response verification Technical implementation steps Illegal lock picking scenario simulation During transportation, the steel wire rope (3) is cut by hydraulic pliers, causing the insertion rod (9) to separate from the conductive contact piece (4), thus disconnecting the closed circuit; The control unit identifies the abnormality through level detection (steps S5-S6) and marks the event level as "level 3 alarm"; Multi-level alarm triggering The monitoring management platform simultaneously performs the following operations: Send an alarm text message containing geographic coordinates to the preset responsible person's mobile phone; Freeze all operation permissions of the electronic lock, and the APP will display the "locked" status; Path deviation handling verification Artificially modifying the transport route so that the vehicle deviates from the preset route by more than 5 kilometers; The platform uses AI algorithms to compare Beidou trajectory data and identifies a route deviation that lasts for 30 minutes, automatically triggering the following actions: Push secondary alarms to the platform and generate electronic evidence of geo-fences; Technical effect verification Response time: The entire process from abnormality occurrence to alarm push is ≤ 1 second, which is 99.9% more efficient than traditional manual inspection (average 30 minutes); Anti-replacement effectiveness: In the simulation test, any unauthorized unlocking or path tampering was blocked by the system, and the success rate of material replacement was 0%.

[0029] Comparative example: Existing mechanical lock + GPS positioning solution Technical implementation Hardware Configuration Ordinary mechanical padlocks (tensile strength 100N) are used to fix materials, and GPS locators are installed independently to report location data every hour through the 2G network; Operation process Manual locking during loading, no authorization verification process, and the key is kept by the driver; The monitoring center relies on manual checking of GPS tracks and calls the driver to confirm if any anomalies are found; Defect Analysis Weak anti-destruction ability: The mechanical lock can be destroyed by hydraulic pliers within 20 seconds, and there is no real-time alarm function (the electronic lock of the present invention takes more than 10 minutes to crack); Serious data gaps: There is a serious data loss phenomenon in areas without signals, which makes it impossible to accurately determine whether you have entered a high-risk area (such as a border line); Lack of authority management: keys are easily copied, and the success rate of simulating collusion between insiders and outsiders to exchange materials reached 37% in the test; Delayed response: The average time it takes to manually discover a path deviation is 52 minutes, and the risk of replacement during this period is extremely high; in conclusion The comparison data of Examples 1-2 and Comparative Examples show that: The Beidou positioning accuracy of the present invention is at the meter level, and the data loss and the problem of being unable to judge the time are solved by supplementary transmission of data in the signal blind area.
