Development Scope
Device and interface access
Integrate GNSS, 4G, motion detection and power management, define positioning frequency, upload cycle, sleep wake-up and device identity.
Product business functions
Integrate GNSS and 4G to develop location collection, mobile wake-up, trajectory, electronic fence, low battery alarm and map display.
Platform and data connection
Combined with the business links of sensing and positioning → event and batch records → 4G → trajectory and environment management → disposal and traceability, the device identity, data fields, update time, abnormal status and result confirmation method are defined.
Exception handling and operational constraints
The position is provided by GNSS or the agreed positioning method, and 4G is responsible for transmission; occlusion, installation and work cycle need to be included in positioning and endurance verification.
Data and Operational Workflow
Movement or scheduled wake-up → Obtain location and positioning status → 4G reporting → Track, electronic fence and asset files.
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: positioning method, antenna installation, work cycle and electronic fence 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 position, time, speed and positioning valid marks. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test mobile wake and still sleep. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Verify no location, no network and fence boundary events. |
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
4G What determines the positioning accuracy of the locator?+
Accuracy depends on positioning receiver, antenna, algorithm and field environment. 4G is mainly responsible for data transmission. The project should record positioning efficiency, errors and reporting conditions according to the actual installation method and route.
Can I delegate only part of the functionality of the GNSS Asset Locator?+
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 the "positioning method, antenna installation, working cycle and electronic fence 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 positioning method, antenna installation, working cycle and electronic fence rules; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
