1. Project Background
To implement regular urban domestic garbage sorting management, solve pain points including the lack of digital ledgers for merchant waste delivery, uncountable waste collection data and insufficient quantitative indicators for environmental assessment, we developed a lightweight WeChat mini-program — Merchant Weighing Management System for Garbage Sorting Experience Center. Targeting garbage sorting operation administrators and local merchants, it forms a closed-loop digital management tool covering the whole chain of merchant waste delivery: registration, archiving and data statistics.
2. Core Functions of Two Portals
(1) Administrator Portal
- Account Login: Administrators log in with username and password to access the waste delivery registration console. A merchant portal entrance at the bottom enables quick switch to merchant interface.
- Delivery Registration Process: Fill in waste weight, scan merchant QR code to bind merchant ID, upload on-site delivery photos, then click "Confirm Delivery" to automatically archive records after complete information input.
- Delivery Data Statistics: Built-in merchant delivery statistics module supports free data filtering by year and month. The dashboard displays total monthly waste weight of all merchants in the area, and a table lists merchant name, unique ID and cumulative monthly delivery weight for quantitative garbage sorting assessment.
- Basic Account Management: Support log-out to switch administrator accounts, suitable for shift work of multiple operation staff.
(2) Merchant Self-service Portal
- Merchant Identity Verification: Merchants get exclusive QR codes bound to unique merchant IDs (e.g. B01, B02) after login, with one-click refresh function for waste collection administrators to bind delivery records via scanning.
- Weighing Record Inquiry: Merchants independently check monthly aggregated waste delivery ledgers with weight and timestamp data for self-audit and environmental compliance inspection.
- Merchant Management Tools: Merchant unbinding function is available for business scenarios such as store closure, relocation and merchant ID modification.
3. Project Value
- Digital Ledger: Replace paper registration. All records including waste weight, merchant info and on-site photos are permanently stored online, available for instant traceability during environmental inspections and garbage sorting supervision.
- Quantitative Assessment Support: Automatically aggregate monthly delivery data to compare waste output of different merchants, providing accurate data support for garbage sorting reward and punishment policies.
- Low-cost Lightweight Solution: Developed on WeChat mini-program without APP download requirement, cutting hardware and software investment for garbage sorting operation.
- Two-way Collaborative Management: Administrators complete offline waste collection registration while merchants check personal delivery data independently. Information exchange between management and merchants greatly improves the efficiency of coordinated garbage sorting governance.

A hospital's logistics operation and maintenance management system
This project is an integrated smart logistics digital management platform built for modern general hospitals. It adopts a unified login portal integrating four core modules: Operation & Maintenance BIM Visual System, Logistics Operation Management System, Security Management BIM System and Work Order System. Based on a full-professional 3D BIM digital twin model of the hospital, the platform integrates capabilities including electromechanical pipeline viewing, equipment monitoring, energy consumption control, environmental quality supervision and medical supporting management. Meanwhile, it covers full-process logistics businesses such as maintenance, inspection scheduling, asset contracts, fixed assets, uniform management and quotation. It realizes visualized hospital building space, online equipment maintenance and standardized logistics workflows, solving pain points of traditional hospital logistics such as inefficient drawing retrieval, slow repair request circulation, scattered equipment ledgers and weak energy consumption control. It provides digital support for refined, intelligent and integrated operation of hospital logistics.
Robot dog inspection system
Traditional manual inspection suffers low efficiency, high risks and untraceable data. Our self-developed quadruped robot inspection management system adopts four-legged robots to cover equipment monitoring, EHS management and material transport. It realizes full digital operation & maintenance, cuts costs, improves efficiency and builds an unattended intelligent inspection system.
地面端態勢可視化平台
The Ground Terminal Situation Visualization Platform is an all-domain command and dispatch visualization system for UAV cluster operations. Based on electronic geographic base maps, it realizes one-map real-time display of all elements including UAVs, mission targets and airborne payloads. The platform integrates core capabilities such as UAV flight status monitoring, photoelectric pod payload data return, target behavior tracking, remote command issuance, mission statistics and intelligent autonomous allocation. It supports remote control of single/multiple UAVs, fixed-point reconnaissance, regional patrol and multi-aircraft collaborative task scheduling. Real-time sensor data including three-axis attitude, infrared/visible light focal length, ranging value, longitude & latitude, flight speed and altitude can be displayed intuitively. Applicable to security inspection, sea area supervision, emergency reconnaissance, land patrol and other scenarios, the platform provides integrated visualized command, parameter configuration and mission management for UAV cluster operations.
