Engineering Scope
The development of low-power wireless vibration monitoring nodes is oriented to the usage requirement of "motors and fans need to obtain vibration status periodically", 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 acceleration acquisition, sampling window, basic feature calculation, batch reporting, raw data on-demand reading and parameter management.
Power Supply and State Scheduling
Continuously collect a window during the agreed period, extract features, save event waveforms and upload them in batches.
Data and System Integration
Clarify the connection and data format around the acceleration sensor interface, installation direction, sampling rate and sampling bandwidth, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form a comparison record of sampling driver, feature code, waveform format and vibration source, focusing on verifying the sampling bandwidth, window length, calculation energy and coverage difference between continuous monitoring and intermittent collection.
System Architecture and Operation
Continuously collect a window during the agreed period, extract features, save event waveforms and upload them in batches.
- Interface composition: acceleration sensor interface, installation direction, sampling rate and sampling bandwidth.
- 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
Basic feature statistics and fault classification are defined separately, and the diagnostic model requires additional samples.
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.

Is it possible to upload only the features without uploading the original waveform?+
It can be designed according to the business, but the information required for diagnosis should be retained and the abnormal waveform reading mechanism should be agreed upon; it is necessary to compare the characteristic calculation and reduce the total energy consumption after uploading.
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 acceleration sensor interface, installation direction, sampling rate and sampling bandwidth, and then determine the modification and regression testing scope.
How to determine the cost and period of this project?+
The evaluation is split based on the delivery items such as sampling driver, feature code, waveform format and vibration source comparison record; the prototype material, structure, platform, external testing and new functions are listed separately, and the quotation and milestones are formed after the requirements and interfaces are confirmed.
