Engineering Scope
The low-power water gauge image acquisition terminal is developed to meet the usage requirement of "remote water gauges need to take pictures regularly to retain the on-site status", 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
Development cycle wake-up, imaging parameters, image compression, local storage and cellular upload; the water gauge reading algorithm can be an independent item.
Power Supply and State Scheduling
Shoot according to time, upload images or processing results in the agreed window, and save them locally when the network is abnormal.
Data and System Integration
Clear connections and data formats around the camera, fixed water gauge field of view, optional fill light, communication and energy storage, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form imaging control, picture storage, upload interface and on-site picture recording, focusing on verifying single startup and upload energy, shadow rain and fog imaging, collection cycle and network disconnection retry.
System Architecture and Operation
Shoot according to time, upload images or processing results in the agreed window, and save them locally when the network is abnormal.
- Interface composition: camera, fixed water gauge field of view, optional fill light, communication and energy storage.
- 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
Image acquisition and water gauge reading algorithms agree on data and acceptance indicators respectively.
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 water gauge reading identification included by default?+
It can be evaluated as an independent module, which requires target water gauge, distance, angle and rain and fog samples. The recognition results and equipment energy consumption are tested separately.
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 camera, fixed water gauge field of view, optional fill light, communication and energy storage, and then determine the scope of changes and return.
How to determine the cost and period of this project?+
The evaluation is split based on the delivery items such as imaging control, picture storage, upload interface and on-site picture recording; 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.
