Development Scope
Device and interface access
Adapt switch, dimming, power and loop status interfaces to establish lamp or control box grouping, time period plan and device address.
Product business functions
Develop group switches, time period plans, brightness interfaces, fault collection, power statistics and local plan execution when the network is disconnected.
Platform and data connection
Combined with the business links of field instruments and facilities → local rules or collection → 4G → group management → inspection and service tasks, the device identity, data fields, update time, abnormal status and result confirmation method are defined.
Exception handling and operational constraints
The dimming protocol, clock and local plan need to be confirmed at the same time; when the public network is lost, it will still operate according to the confirmed local policy.
Data and Operational Workflow
Platform setting plan → 4G synchronization → local scheduled execution → loop and power feedback → fault recording and maintenance.
The device side, communication side and platform side retain necessary status and logs respectively. Project integration testing is checked with actual equipment data and execution results, and network connection status and business completion status are recorded separately.
Project Inputs
- Existing device models, interface and wiring diagrams, licensing agreements, data samples and available codes.
- Business processes and parameters: dimming protocol, loop grouping, local clock and plan priority.
- Target location, operator, SIM/APN, power supply, installation method and equipment size.
- Existing platform interfaces, user roles, development modules, number of prototypes and planned nodes.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| product realization | Hardware design data, prototypes or existing equipment modification data involved in the project, as well as corresponding firmware and interfaces | Verify grouping switches and time slot plans. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Check the dimming value, loop feedback and energy consumption fields. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Test clock correction, network outage and power outage recovery. |
First confirm the scope and key functions, then complete prototype or software development, system integration testing and stage acceptance. The acceptance conditions list the prototype, version, environment, duration and passing threshold; source code, design documents, third-party licenses, materials, traffic, cloud resources and on-site work are agreed separately.
Frequently Asked Questions
Can street light control plans be executed offline?+
The plan can be stored locally in the controller for execution, and the version and effective time can be recorded. It is necessary to clarify the handling of clock abnormalities, power outage recovery, and holiday plan conflicts, and then conduct on-site verification.
Is it possible to entrust only part of the functions of the centralized streetlight controller?+
The device interface, terminal program, 4G communication and platform integration testing can be split based on the existing R&D foundation. Please provide existing information and target boundaries, first check the "dimming protocol, loop grouping, local clock and plan priority", and then clarify the deliverables and interface responsibilities of each module.
How are costs and cycle time assessed?+
Split the workload based on target devices, interfaces, existing data, and verification criteria. This project focuses on checking the dimming protocol, loop grouping, local clock and plan priority; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
