Engineering Scope
The development of solar low-power telemetry collectors is oriented to the use requirement of "existing instruments in the field that require solar power supply for collection and uploading". 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 photovoltaic charging, energy storage management, instrument branch power supply, serial acquisition, energy-aware scheduling and remote data access.
Power Supply and State Scheduling
Start instrument collection according to the energy budget, upload in batches, and perform agreed degradation tasks when energy is insufficient.
Data and System Integration
Clear connections and data formats around photovoltaic input, energy storage, serial instruments and shunt power supplies, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Charging and power supply circuits, instrument adaptation, scheduling firmware and energy balance records are formed, focusing on verifying season and shading conditions, length of operation without light, load starting current and low power strategy.
System Architecture and Operation
Start instrument collection according to the energy budget, upload in batches, and perform agreed degradation tasks when energy is insufficient.
- Interface composition: photovoltaic input, energy storage, serial instrument and shunt power supply.
- 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 photovoltaic rated power cannot be directly used as the daily available energy at the installation location.
Energy acquisition and load budgets should be confirmed simultaneously with functional indicators. Record the energy availability period, energy storage devices, temperature, working cycle and communication conditions, and provide budget results and actual measurement records of energy balance and expenditure for the complete cycle.
