Verified Projects and Demo Cases
Page Guide
1. Case Background
The demo environment simulates a typical municipal sensing scenario of an urban district, covering three types of high-frequency O&M targets:
- Lighting facilities: several street light control boxes, requiring remote switching, dimming, and fault reporting.
- Drainage facilities: water-level gauges at low-lying points and drainage pumps, requiring fast handling when waterlogging risk appears.
- Security facilities: cameras at intersections and key areas, requiring unified viewing together with IoT devices.
The goal of the demo is not to verify the connectivity of a single device, but to verify the complete closed loop of "multiple device types on one platform": unified access, unified modeling, linked handling, and centralized O&M — all completed within the FastBee platform without relying on third-party middleware.
2. Solution Implementation
2.1. Device Access and Networking
Implementation proceeded in batches by device type. Street light control boxes and water-level gauges were connected through edge gateways over the Modbus protocol, with register mapping and data format conversion completed on the gateway side; manhole cover displacement sensors and drainage pump controllers were connected directly to the platform over MQTT; cameras were connected via the GB28181 national standard and brought into the same device list for management.
Each device type was created as an independent product on the platform and bound to a Thing Model: street lights define switch status and brightness properties plus light-switching functions; water-level gauges define a water-level property and an over-limit event; drainage pumps define a running status property and start/stop functions.
2.2. Scene Linkage Configuration
Linkage rules were configured around the drainage scenario: when a water-level gauge reports a level above the threshold, the Rule Engine automatically delivers a start command to the drainage pump and pushes an alert to the operations staff's mobile app; after the water level falls back to the safe range, the pump is stopped automatically and a recovery notification is generated. For the lighting scenario, scheduled linkage was configured to switch street lights on and off in batches according to a sunrise/sunset plan.
3. Feature Showcase
The demo environment's dashboard displays device distribution and operating status by block: online devices, pending events, and alert sites are marked in different colors, and the right side summarizes the access overview and per-district operation statistics, giving the command center a global view on one screen.
Beyond the dashboard, the demo also covers the following capability areas:
- Device Management: view device lists and online status by product; the device detail page supports real-time property viewing, remote control, and reported-log backtracking.
- Alert Center: events such as device offline, water level over-limit, and manhole cover displacement generate alerts by severity, with handling status traceable throughout.
- Mobile app: operations staff view device details, execute control, and confirm alert handling results from their phones on site.
- Video surveillance: connected cameras support PTZ direction and zoom control, real-time streaming, and recording playback.
4. Operating Results
During the demo period, multiple types of devices stayed stably online within the same platform, and protocol differences were completely transparent to upper-layer applications. Drainage linkage — from the water level exceeding the limit to pump startup — was handled fully automatically, with no need for staff to confirm on site before operating, noticeably speeding up the handling response; alerts changed from "discovered afterwards" to "pushed in real time", and inspection routes for operations staff are now driven directly by the alert sites on the dashboard.
This demo verified the feasibility of the reference solution's four-layer architecture and core functions under a real device mix. The same-scope capabilities have been applied at scale in the complete smart agriculture case — see the Smart Agriculture Verified Case for actual system interfaces of the workbench, dashboard, and mobile app. Another published urban-scenario project is the parking lot retrofit, detailed in Retrofitting an Old Parking Lot with IoT; for the design thinking behind linkage rules, see Rule Engine and Scene Linkage.
5. FAQ
Is this demo case a real customer project?
This page records the verification process in a demo environment, used to showcase the platform's capability mix in urban scenarios, and does not involve specific customer information; for a published real-project retrospective in the city direction, see Retrofitting an Old Parking Lot with IoT.
What types of devices were connected in the demo environment?
Street light control boxes, manhole cover displacement sensors, water-level gauges, drainage pump controllers, and cameras were connected via Modbus, MQTT, and GB28181 respectively, all managed uniformly with the Thing Model.
How was the drainage linkage in the demo implemented?
A water-level gauge reporting an over-limit value triggers the Rule Engine, which automatically delivers a start command to the drainage pump and pushes an alert to the mobile app; the pump stops automatically after the water level falls back, with no manual intervention throughout. For the configuration approach, see the Scene Linkage section of the Multi-Type Device Access and O&M Reference Solution.
Where can I see screenshots of the real system?
The complete smart agriculture case shows real system interfaces of the workbench, dashboard, mobile app, device management, Scene Linkage, and monitoring, with platform capabilities at the same scope as the city demo — see the Smart Agriculture Verified Case.
