Development Scope
Device and interface access
Access liquid level, pressure, flow, pump operation and fault signals, and realize status reading and authorization command docking according to the control cabinet interface.
Product business functions
Collect liquid level, pressure, pump status and faults, and develop control permissions, command acknowledgments, local interlocking interfaces and platform monitoring.
Platform and data connection
Combined with the business link of water level and rainfall and meter →
Exception handling and operational constraints
Pump protection, emergency stop and necessary interlocking are executed locally; remote instructions specify validity period, priority and on-site/remote switching conditions.
Data and Operational Workflow
On-site status collection → 4G telemetry → platform research and judgment → authorized command → local interlocking check → execution feedback and operation traces.
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: pump and instrument interface, field interlocking, manual and automatic priority and execution feedback.
- 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 pump status, instrument readings and alarm mapping. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test for duplicate, expired, and commands that do not meet interlock conditions. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Verify the control behavior when the network is disconnected and the status synchronization after the network is restored. |
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
How does the water pump operate after the network is disconnected?+
Retain local automatic or manual logic based on process and control cabinet capabilities. The project needs to clarify the operation strategy, on-site priority and status synchronization after recovery when the network is disconnected, so as to avoid re-executing expired commands.
Can I entrust only some functions of the pump station monitoring terminal?+
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 "pump and instrument interface, on-site interlocking, manual and automatic priority and execution feedback", 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 pump and instrument interface, on-site interlocking, manual-automatic priority and execution feedback; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
