Development Scope
Device and interface access
Access GNSS, operating status, job switch or equipment bus, and establish the association between personnel, equipment, plots and task numbers.
Product business functions
Access to GNSS and job status signals, development trajectory, working hours, task binding, network disconnection cache and platform statistics; the area algorithm is determined separately.
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
Transportation and actual operations should be distinguished; area calculations require determination of track quality, operating width, repeat coverage and plot boundary rules.
Data and Operational Workflow
Job status collection → Track and time correlation → Offline saving → 4G upload → Work hours and task statistics.
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: positioning and operation signals, task numbers, trajectory quality and working hours.
- 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 start, stop and trajectory time of the job. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test without location, offline and task switching. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Verify hours and status statistics against field records. |
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 working area be counted at the same time?+
Can be evaluated as a stand-alone feature, requiring confirmation of positioning method, working width, parcel boundaries and overlap deduction rules. First establish reference data and error standards, and then develop and verify the algorithm.
Can I entrust only part of the functions of the agricultural machinery operation monitoring 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 data and target boundaries, first check "positioning and operation signals, task number, trajectory quality and working hours caliber", 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 positioning and operation signals, task numbers, trajectory quality and working hours; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
