Development Scope
Device and interface access
Read operation, power or vibration status, develop working hours accumulation, battery detection, tamper event and project binding interfaces.
Product business functions
Access operation and power status, develop working hours accumulation, anti-tamper events, maintenance thresholds, project binding and leasing backend interfaces.
Platform and data connection
Combined with the business link of device bus and status → operation and maintenance terminal → 4G → tasks and device files → diagnosis and maintenance, the device identity, data fields, update time, abnormal status and result confirmation method are defined.
Exception handling and operational constraints
The power-on time and the actual operation time are defined separately; billing caliber, equipment replacement and history record modification require clear permissions.
Data and Operational Workflow
Equipment working status → Local working hours accumulation → 4G upload → Rental project association → Maintenance reminder and usage report.
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: work status identification, working hours, anti-demolition and rental project binding.
- 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 | Verify work accrual against reference records. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test short-term start and stop, power-off storage and anti-tampering. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Check project changes, maintenance intervals and repeated uploads. |
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 the power-on time be directly used as rental working hours?+
Depends on contract and business definition. If it is necessary to record the actual operating time, the operating status should be identified based on operating signals or equipment protocols, and then the statistical methods for pause, standby and abnormal periods should be agreed upon.
Can I entrust only part of the functions of the rental equipment time management terminal?+
The device interface, terminal program, 4G communication and platform integration testing can be split based on the existing R&D foundation. Please provide existing information and target boundaries, first check "working status identification, working hours, anti-tampering and leasing project binding", 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 working status identification, working hours, anti-tampering, and rental project binding; when prototypes, on-site integration testing, or third-party platform cooperation are required, the corresponding costs, prerequisites, and milestones will be listed separately.
