Engineering Scope
The development of low-power instrument image collectors is oriented to the use requirement of "instruments that are inconvenient to be modified and require image reading", and 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 fixed field of view, wake-up shooting, fill light, image or reading buffering and periodic transmission; identification module is evaluated on a sample basis.
Power Supply and State Scheduling
After waking up, stabilize the exposure and shoot, save the image or reading as agreed, and then return to sleep.
Data and System Integration
Clarify the connection and data format around the fixed field of view of the instrument, camera, fill light and reading interface, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form imaging module adaptation, exposure configuration, reading interface and power supply switching records, focusing on verifying the consistency of wake-up imaging, fill light energy, recognition effect and overall energy consumption.
System Architecture and Operation
After waking up, stabilize the exposure and shoot, save the image or reading as agreed, and then return to sleep.
- Interface composition: instrument fixed field of view, camera, fill light and reading 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
Instrument type, reflectivity, installation and identification samples determine the scope of algorithm development.
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 | Instruments that are inconvenient to retrofit require image reading; provide typical usage procedures, sampling and upload times, target battery life, and response requirements. |
| Product interface and structure | The instrument has a fixed field of view, camera, fill light and reading interface; 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 | Imaging module adaptation, exposure configuration, reading interface and power supply switching records; the scope of hardware, source code and third-party components are clearly stated in the statement of work. |
| Functional verification | After waking up, stabilize the exposure and shoot, save the image or reading as agreed, and then return to sleep; record the input, output and recovery results of each state. |
| Power consumption verification | Wake-up imaging consistency, fill light energy, recognition effect and overall energy consumption were tested separately. 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. |

How to deal with the inconsistent screen after every power-on?+
It is necessary to control the exposure and fill light stabilization process, determine the effective frame selection conditions, and then verify the consistency of the image or reading. The first frame cannot be used directly.
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 fixed field of view, camera, fill light and reading interface of the instrument, 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 imaging module adaptation, exposure configuration, reading interface and power supply switching 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.
