Engineering Scope
The low-power battery irrigation valve controller is developed to meet the usage requirement of "decentralized irrigation valves need to be switched on and off as planned", and the collection, processing, communication and power supply are designed as one set of products. The project can start from new main board development, existing firmware modification or designated module integration. The development scope is confirmed based on the target function, existing foundation and delivery requirements.
Interfaces and Product Integration
Develop drivers, action readbacks, local plans, remote tasks, low power handling and communication windows that match the valve type.
Power Supply and State Scheduling
Receive and save the plan, execute actions on time, and check feedback; run according to local rules when disconnected.
Data and System Integration
Clear connections and data formats around valve coils or motors, batteries, drive axles and action feedback, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form the valve control main board, execution state machine, plan protocol and stall test records, focusing on verifying the valve action energy, stall or failure retry, offline plan and low voltage recovery.
System Architecture and Operation
Receive and save the plan, execute actions on time, and check feedback; run according to local rules when disconnected.
- Interface composition: valve coil or motor, battery, drive axle and action feedback.
- Work scheduling: Determine each status based on sampling, interaction and reception requirements, indicating which circuits continue to run.
- Exception handling: Define deadlines, bounded retries, and recovery behaviors for applicable communication, sensing, or execution tasks.
Design Conditions and Functional Limits
The valve type, holding method and number of actions directly affect the power supply scheme that can be realized.
Define power targets together with functional requirements. Battery-life estimates must specify the battery, temperature, operating cycle, event frequency and network conditions. Keep estimates separate from continuous-operation test results.
Project Inputs

Delivery and Acceptance
| Delivery project | Verification method |
|---|---|
| Design and implementation | The valve control main board, execution state machine, planning protocol and stall test records; the scope of hardware, source code and third-party components are clearly stated in the statement of work. |
| Functional verification | Receive and save the plan, execute actions on time, and check feedback; run according to local rules when disconnected; record the input, output, and recovery results of each state. |

Can I keep trying again after the valve action fails?+
The number and intervals of retries should be limited, mechanical obstruction, low battery and feedback abnormalities should be distinguished, and the results should be reported to prevent continuous driving from consuming stored energy or damaging the actuator.
Is it possible to develop only part of an existing product?+
Module development or power consumption optimization can be carried out according to the existing interface and modifiable range. For this product, you first need to check the valve coil or motor, battery, drive axle and action feedback, and then determine the scope of modification and return.
How to determine the cost and period of this project?+
Based on the valve control main board, execution state machine, planning agreement and stalled test records and other deliverables, the evaluation is split; the prototype materials, structure, platform, external tests and new functions are listed separately, and the quotation and milestones are formed after the requirements and interfaces are confirmed.
