Development Scope
Device and interface access
Adapt to pulse, RS-485 or customer-specified meter protocols to establish meter address, magnification, unit, cumulative amount and time freezing rules.
Product business functions
Adapt to pulse or serial meter protocols and develop reading collection, magnification conversion, time freezing, replacement copying and usage statistics.
Platform and data connection
Combined with the business link of water level and rainfall and meter →
Exception handling and operational constraints
The cumulative amount, time period consumption and meter replacement need to be distinguished; the development of collection links does not change the measurement characteristics of the original meter.
Data and Operational Workflow
Meter reading → Legality check → Freezing and local saving → 4G upload → Usage statistics and re-copying verification.
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 process and parameters: meter protocol, address and multiplier, freezing time point and meter replacement 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 bottom of the table, magnification and statistical usage. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Verify power outage count saving and repeated copying. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Test table replacement, address conflicts and single-table communication timeout. |
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 meters from multiple manufacturers be connected to the same collector?+
The protocol and address can be configured separately, but each model information needs to be provided. The bus load, polling duration, field definitions and frozen diameters should be checked at the same time to ensure that platform statistics are consistent with on-site meter measurements.
Can I entrust only part of the functions of the remote meter reading collector?+
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 "metering protocol, address and magnification, freezing time point and meter replacement 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 meter agreement, address and magnification, freezing time point and meter replacement rules; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
