Development Scope
Device and interface access
Adapt water level, rainfall, power supply and status input, and clarify the telemetry station address, message format, timing reporting and event reporting rules.
Product business functions
Access water level and rainfall equipment, and develop scheduled reporting, event reporting, clock management, telemetry protocol adaptation and low battery processing.
Platform and data connection
Combined with the business link of water level and rainfall and meter →
Exception handling and operational constraints
The protocol version, platform implementation and test station parameters need to be confirmed at the same time; additional reporting of emergencies must not cause unlimited retries or queue congestion.
Data and Operational Workflow
Water level and rainfall collection → time stamp and local records → timing or event reporting → platform response → retransmission of unconfirmed messages.
The device side, communication side and platform side retain necessary status and logs respectively. Project integration testing is checked with actual equipment data and execution results, and network connection status and business completion status are recorded separately.
Project Inputs
- Existing device models, interface and wiring diagrams, licensing agreements, data samples and available codes.
- Business processes and parameters: telemetry protocol version, site code, water level and rainfall caliber, and event reporting rules.
- Target location, operator, SIM/APN, power supply, installation method and equipment size.
- Existing platform interfaces, user roles, development modules, number of prototypes and planned nodes.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| product realization | Hardware design data, prototypes or existing equipment modification data involved in the project, as well as corresponding firmware and interfaces | Check the water level dimension, rainfall accumulation and timestamp. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Verification threshold reporting, periodic reporting and response timeout. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Test configuration, counting and data to be sent after power outage recovery. |
First confirm the scope and key functions, then complete prototype or software development, system integration testing and stage acceptance. The acceptance conditions list the prototype, version, environment, duration and passing threshold; source code, design documents, third-party licenses, materials, traffic, cloud resources and on-site work are agreed separately.
Frequently Asked Questions
Can it be adapted to specified hydrological telemetry protocols?+
It can be developed based on the protocol version, message sample and platform test environment provided by the customer. It is necessary to clarify the mandatory and optional messages, device encoding, verification, response and retransmission rules before integration testing.
Is it possible to delegate only part of the functionality of Hydrographic Telemetry RTU?+
The device interface, terminal program, 4G communication and platform integration testing can be split based on the existing R&D foundation. Please provide existing data and target boundaries, first check the "telemetry protocol version, site code, water level and rainfall caliber and event reporting rules", and then clarify the deliverables and interface responsibilities of each module.
How are costs and cycle time assessed?+
Split the workload based on target devices, interfaces, existing data, and verification criteria. This project focuses on checking the telemetry protocol version, site code, water level and rainfall caliber, and event reporting rules; when prototypes, on-site integration testing, or third-party platform cooperation are required, the corresponding costs, prerequisites, and milestones will be listed separately.
