Development Scope
Device and interface access
Adapt to the authorized CAN or serial port protocol, access working hours, faults, locations and maintenance counts, and distinguish the data sources of the controller and additional sensors.
Product business functions
Interface with authorized CAN or serial port protocol, develop working hours, fault, location and maintenance data collection, and complete cloud device files and reports.
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
Reading parameters and mechanical control should be separated; the impact of newly added communication terminals on the original bus, power supply and complete device work should be verified.
Data and Operational Workflow
Mechanical status collection → local recording and aggregation → 4G return → equipment files → maintenance plan and after-sales diagnosis.
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: mechanical model, authorized bus protocol, working hours fault field and power supply conditions.
- 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 working hours, fault codes and original instruments. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test bus load, node disconnection and reconnection. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Verify startup power supply changes, data caching and maintenance reminders. |
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 different types of construction machinery share terminals?+
The hardware and platform foundation can be reused, but the bus protocol, power supply, wiring harness and installation conditions need to be confirmed separately. After establishing field mapping and verification records for each model, it is then included in the adaptation list.
Can I entrust only part of the functions of the construction machinery remote information 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 the "mechanical model, authorized bus protocol, working hours fault field and power supply conditions", 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 mechanical model, authorized bus protocol, working hours fault field and power supply conditions; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
