Development Scope
Device and interface access
Connect valves, water pumps, soil and flow signals, and clarify the driving electrical conditions, zone numbers and valve and pump start and stop sequences.
Product business functions
Connect soil and flow sensors to develop valve and pump interfaces, zoning plans, execution feedback, offline plans and abnormal shutdown strategies.
Platform and data connection
Combined with the business link of sensor → local collection and control → 4G → remote configuration and alarm → job record, the device identity, data fields, update time, abnormal status and result confirmation method are defined.
Exception handling and operational constraints
After the control plan is issued, offline execution, undervoltage, no water, and flow abnormality handling should be defined. Networking does not replace equipment protection.
Data and Operational Workflow
Irrigation plan or authorized operation → Local condition check → Valve and pump execution → Flow and status feedback → 4G upload task record.
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: irrigation zones, valve and pump interfaces, start-stop sequence and water shortage protection.
- 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 partition order, plan conflicts, and execution times. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Check valve pump feedback and abnormal shutdown. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Test the task status after network disconnection, power outage and repeated instructions. |
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 I irrigate automatically according to soil moisture?+
Local rules can be designed based on probe location, thresholds, hysteresis and irrigation schedules. It is necessary to confirm the control parameters based on soil, crop and water supply conditions, and verify the handling of sensor failure.
Can I delegate only part of the functionality of a smart irrigation 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 "irrigation zones, valve and pump interfaces, start-stop sequence and water shortage protection", 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 irrigation zones, valve and pump interfaces, start-stop sequences and water shortage protection; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
