Engineering Scope
The development of low-power portable data collectors is oriented to the usage requirement of "field testing requires offline recording of multiple sensor data", 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 channel scheduling, sensor power supply, sampling recording, display, sleep and USB/Bluetooth export.
Power Supply and State Scheduling
Arrange stimulation and sampling by channel, record complete data, and turn off non-essential peripherals when idle.
Data and System Integration
Clarify connections and data formats around multi-channel sensors, excitation, ADC, display and export interfaces, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form channel drivers, storage formats, export tools and power-off recovery tests, focusing on verifying each channel excitation, stabilization time after power switching, recording continuity and wake-up recovery.
System Architecture and Operation
Arrange stimulation and sampling by channel, record complete data, and turn off non-essential peripherals when idle.
- Interface composition: multi-channel sensor, excitation, ADC, display and export 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
Measuring range, sampling frequency and measurement error are confirmed by specific channels.
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
| Data category | Startup data |
|---|---|
| business work cycle | Field testing requires offline recording of multi-channel sensor data; typical usage procedures, sampling and upload times, target battery life and response requirements are provided. |
| Product interface and structure | Multi-channel sensors, excitation, ADC, display and export interfaces; for existing products, provide schematics, a bill of materials (BOM), firmware and prototypes. |
| Batteries and site conditions | Provide battery model, power supply range, cut-off voltage, temperature, installation method and communication conditions. |
| Delivery and Responsibility | Clarify the scope of source code and design files, platform docking, number of prototypes, test conditions and third-party work. |
Delivery and Acceptance
| Delivery project | Verification method |
|---|---|
| Design and implementation | Channel drivers, storage formats, export tools and power-off recovery testing; the scope of hardware, source code and third-party components are clearly stated in the statement of work. |
| Functional verification | Arrange stimulation and sampling by channel, record complete data, turn off non-essential peripherals when idle; record the input, output and recovery results of each state. |
| Power consumption verification | Each channel excitation, settling time after power switch, recording continuity and wake-up recovery. Fix the battery side measurement point to record the energy from the full task cycle until the device returns to sleep. |
| Exceptions and retesting | Covers applicable situations such as low battery, continuous triggering, loss of connection or restart, and retains original logs, waveforms and versions. |

Explore the ScopeFrequently Asked Questions
Is the power consumption of external sensors also included in the battery life?+
If it is powered by an instrument battery, it should be included in the battery-side measurement of the complete device; for externally powered sensors, the measurement boundaries and interface power consumption need to be explained.
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 multi-channel sensor, excitation, ADC, display and export 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 deliverables such as channel drivers, storage formats, export tools and power-off recovery tests; the prototype materials, structure, platform, external tests and new functions are listed separately, and quotations and nodes are formed after the requirements and interfaces are confirmed.
