Development Scope
Device and interface access
Develop lock control driver, lock state, anti-tamper and identity verification interface, design instruction validity period, local feedback and abnormal power supply handling.
Product business functions
Develop lock control interface, lock status feedback, anti-tamper events, identity verification, command timeliness verification, authority management and operation traceability.
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 fact that the platform has sent a command does not mean that the mechanical lock has been activated. The unlocking result should be based on the lock status and agreed feedback; it should be confirmed separately through offline authorization.
Data and Operational Workflow
Authorization application → Platform permission verification → 4G command → Local execution verification → Lock status feedback → Operation record.
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: lock driver, lock status feedback, anti-tamper events and instruction validity period.
- 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 | Test authorization, override and expired commands. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Verify mechanical jamming, inconsistent lock status and tamper-evident events. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Test the command deduplication after power off and reconnection. |
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
How does the platform confirm that the lock has been opened?+
The terminal needs to read the lock state or agreed execution feedback and associate the command identifier with the result. Record the status of stuck, timeout and feedback conflicts respectively to avoid relying solely on network delivery as the basis for successful unlocking.
Can I entrust only part of the functions of electronic locks and electronic seals?+
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 "lock driver, lock status feedback, anti-tamper events and instruction validity period", 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 lock drive, lock status feedback, anti-tamper events and instruction validity period; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
