Engineering Scope
The development of low-power equipment operation timing terminal is oriented to the usage requirement of "non-networked equipment needs to record startup, shutdown and operation time", and the collection, processing, communication and power supply are designed as one set of products. The project can start from new main board development, existing firmware modification or designated module integration. The development scope is confirmed based on the target function, existing foundation and delivery requirements.
Interfaces and Product Integration
Adapt to dry contacts, authorized status output or external sensors, and develop status wake-up, working hours accumulation, power-off storage and maintenance reminders.
Power Supply and State Scheduling
The status edge triggers the timing, checks the status periodically, and settles and saves the working hours after shutdown.
Data and System Integration
Clear connections and data formats around dry contacts, operating status outputs or external status sensors, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form the input interface, timing program, power-down record structure and start-stop test cases, focusing on verifying the always-on detection current, short-term start-stop missing records, power-off recovery and repeated counting.
System Architecture and Operation
The status edge triggers the timing, checks the status periodically, and settles and saves the working hours after shutdown.
- Interface composition: dry contact, operating status output or external status sensor.
- Work scheduling: Determine each status based on sampling, interaction and reception requirements, indicating which circuits continue to run.
- Exception handling: Define deadlines, bounded retries, and recovery behaviors for applicable communication, sensing, or execution tasks.
Design Conditions and Functional Limits
The device status identification method needs to be confirmed according to the actual model.
Define power targets together with functional requirements. Battery-life estimates must specify the battery, temperature, operating cycle, event frequency and network conditions. Keep estimates separate from continuous-operation test results.
Project Inputs
| Data category | Startup data |
|---|---|
| business work cycle | Non-networked devices need to record startup, shutdown, and running time; provide typical usage processes, sampling and upload times, target battery life, and response requirements. |
| Product interface and structure | Dry contact, operating status output or external status sensor; for existing products, provide schematics, a bill of materials (BOM), firmware and prototypes. |
| Batteries and site conditions | Provide battery model, power supply range, cut-off voltage, temperature, installation method and communication conditions. |
| Delivery and Responsibility | Clarify the scope of source code and design files, platform docking, number of prototypes, test conditions and third-party work. |
Delivery and Acceptance
| Delivery project | Verification method |
|---|---|
| Design and implementation | The input interface, timing program, power-down record structure and start-stop test cases; the scope of hardware, source code and third-party components are clearly stated in the statement of work. |
| Functional verification | The status edge triggers the timing, checks the status periodically, and settles and saves the working hours after shutdown; records the input, output and recovery results of each status. |
| Power consumption verification | Resident detection current, short-term start and stop leakage recording, power failure recovery and repeated counting. Fix the battery side measurement point to record the energy from the full task cycle until the device returns to sleep. |
| Exceptions and retesting | Covers applicable situations such as low battery, continuous triggering, loss of connection or restart, and retains original logs, waveforms and versions. |

Explore the ScopeFrequently Asked Questions
Will the device be missed if it is started and stopped for a short period of time?+
Identifiable short pulses and debounce times should be specified, and representative start-stop sequence tests should be used; sleep timing and power-off recovery should be verified at the same time to prevent missing records or repeated accumulation.
Is it possible to develop only part of an existing product?+
Module development or power consumption optimization can be carried out according to the existing interface and modifiable range. For this product, you first need to check the dry contacts, operating status output or external status sensors, and then determine the modification and regression testing scope.
How to determine the cost and period of this project?+
The evaluation is split based on the input interface, timing program, power-down record structure, start-stop test cases and other deliverables; the prototype materials, structure, platform, external tests and new functions are listed separately, and the quotation and milestones are formed after the requirements and interfaces are confirmed.
