Engineering Scope
The development of vibration energy collection and monitoring nodes is oriented to the usage requirement of "there is vibration energy next to the operating equipment, and the measurement points are difficult to maintain". 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
First evaluate the vibration spectrum and recoverable energy, and then develop the transducer interface, rectifier energy storage, power supply control and event collection and reporting.
Power Supply and State Scheduling
Energy is obtained when the target equipment is running, collected and reported after the energy storage reaches the working threshold, and tasks are retained according to the policy during shutdown.
Data and System Integration
Clarify connections and data formats around vibration transducers, rectification, energy storage, sensing and wireless interfaces, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form vibration energy measurement, rectifier energy storage circuit, node firmware and working condition records, focusing on verifying working condition changes, energy storage during shutdown, cold start and average energy balance; no replacement batteries are preset.
System Architecture and Operation
Energy is obtained when the target equipment is running, collected and reported after the energy storage reaches the working threshold, and tasks are retained according to the policy during shutdown.
- Interface composition: vibration transducer, rectifier, energy storage, sensing and wireless interface.
- 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
Changes in operating conditions and periods of equipment downtime must be factored into energy availability assessments.
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.

Can the battery be removed if the device vibrates?+
Can't judge directly. Vibration frequency, amplitude, installation coupling and recoverable energy should be measured and compared between cold starts and loads; auxiliary energy storage or adjustment functions may be required.
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 vibration transducer, rectifier, energy storage, sensing and wireless interface, and then determine the scope of changes and regression.
How to determine the cost and period of this project?+
The evaluation is split based on the deliverables such as vibration energy measurement, rectifier energy storage circuit, node firmware and working condition records; the prototype materials, structure, platform, external testing and new functions are listed separately, and the quotation and milestones are formed after the requirements and interfaces are confirmed.
