Description

Technical Field

[0001] The present invention relates to the technical field of express delivery, and in particular to a convenient express delivery station item search alarm system. Background Art

[0002] With the rapid development of e-commerce, the volume of express delivery in urban communities, campuses, and office buildings has increased significantly. To meet the demand for efficiency and experience in the "last mile," various smart express delivery stations have emerged. Traditional delivery stations mainly rely on manual operation or simple prompts (such as SMS verification codes and paper labels) to guide users to pick up their packages. This leads to problems such as long search times for users, high rates of incorrect package pickup, and high labor costs at the stations, making it difficult to adapt to the concurrent demand during peak periods. To improve pickup efficiency, the industry has begun to introduce technologies such as RFID, QR codes, and OCR. By deploying programmable light strips and speakers on shelves or at parcel locations, combined with an "intelligent light strip tracking system" that triggers sound and light prompts when a code is scanned or entered, this system can, to a certain extent, achieve a "goods-to-person" model, significantly improving pickup efficiency. However, in actual applications, the existing intelligent light bar parcel finding system can easily cause visual confusion when multiple users concurrently pick up parcels due to the simultaneous flashing of multiple light bars. When the same pickup code corresponds to multiple parcels or the user enters an incorrect code, it is difficult to distinguish the order of the packages. At the same time, the system lacks priority management and self-checking mechanisms for color coding and flashing frequency, resulting in performance fluctuations and difficult to detect faults in a high-concurrency environment. In addition, the access threshold for devices of different brands or models is high and there is a lack of unified interface standards, resulting in high system upgrade and daily operation and maintenance costs and poor maintainability. Therefore, a convenient express station parcel finding alarm system is proposed to address the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide a convenient express station parcel search alarm system to solve the problem that when multiple users concurrently pick up parcels in the existing intelligent light bar parcel search system, multiple light bars flashing simultaneously can easily cause visual confusion; when the same pickup code corresponds to multiple items or the user enters an incorrect code, it is also difficult to distinguish the order of each package; at the same time, the system lacks priority management and self-checking mechanism for color coding and flashing frequency, and performance is prone to fluctuations and faults are difficult to detect in a high-concurrency environment; in addition, the access threshold for equipment of different brands or models is high and there is a lack of unified interface standards, resulting in high system upgrade and daily operation and maintenance costs and poor maintainability.

[0004] To achieve the above object, the present invention provides the following technical solutions: A convenient express post station missing item alarm system includes an implementation process of the convenient express post station missing item alarm system, and the implementation process of the convenient express post station missing item alarm system includes the following steps: Step 1: The user terminal receives the user's pickup code input or scan information and sends the information to the system background; Step 2: The backend server retrieves the corresponding package record in the package information database based on the pickup code received in step 1, generates a pickup task, and adds the pickup task to the concurrent scheduling queue; Step 3: The concurrent scheduling module sorts all pickup tasks by timestamp based on the first-come, first-served principle.

[0012] As a further optimization of the present invention, the heartbeat detection module also collects and reports the following indicators during each detection: Response delay of the light bar module; The deviation between the actual brightness of the light bar and the preset brightness; The deviation between the actual volume of the speaker and the preset volume; and when any indicator exceeds the preset range, an operation and maintenance alarm is triggered, prompting maintenance or replacement of the corresponding hardware unit.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by constructing a closed-loop process from user scanning the code to completion of pickup, and on this basis introducing technical means such as concurrent scheduling queues, dynamic color coding and flashing frequency management, self-checking heartbeat mechanism and modular interface standards, refined resource allocation and high-availability operation guarantee for multi-user concurrent pickup are achieved: on the one hand, color coding and flashing times dynamically allocated based on priority are linked to sound and light + voice prompts to effectively distinguish different users and multiple packages, eliminating visual confusion and misplacing; on the other hand, through heartbeat detection and key indicator self-checking, real-time monitoring and rapid positioning of hardware or communication anomalies are achieved to ensure system stability without frame drops in high-concurrency scenarios; at the same time, a unified MQTT / WebSocket interface and modular hardware design are adopted to greatly reduce the threshold for access and upgrade maintenance of equipment of different brands, achieve extremely high compatibility and maintainability, and significantly improve the pickup efficiency, service quality and operation and maintenance level of express stations.
