Development Scope
Device and interface access
Connect the temperature and humidity probe and configure the sampling period, time source, over-limit threshold, batch number and local storage capacity.
Product business functions
Develop probe access, timestamp recording, over-limit events, offline storage, supplementary transmission, transportation batch correlation and report export.
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
Data record integrity and temperature measurement errors must be accepted separately; traceability information must be retained on probe location, calibration and transportation processes.
Data and Operational Workflow
Transport batch binding → Continuous sampling and storage → 4G reporting → Over-limit event confirmation → Temperature curve and batch 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: probe calibration, sampling interval, batch number and offline recording duration.
- 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 reading and time against a reference meter. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test offline recording, full storage and supplementary transmission. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Validate overrun duration, recovery, and reporting fields. |
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
Will the records be lost if there is no signal during transportation?+
You can design local storage according to the agreed capacity and make up for the transmission after the network is restored. It is necessary to clarify the maximum offline duration, sampling interval, capacity exhaustion strategy and power outage data protection, and then confirm it through testing.
Can I entrust only part of the functions of the cold chain temperature and humidity recorder?+
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 "probe calibration, sampling interval, batch number and offline recording duration", 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 probe calibration, sampling interval, batch number and offline recording time; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
