Product Overview

How construction companies settle worker hours with labor agencies is one of the major challenges facing the construction industry.

This project aims to provide worker attendance tracking services for a construction company to verify workers’ working hours. 
It requires the provision of worker location tracking and attendance services,

including platform-side statistics on attendance times (with configurable geofences, location trajectories, etc.),

the ability to export data to Excel spreadsheets, and the provision of 20,000 location tracking devices.

Product Appearance




The wristband features a lightweight design to minimize disruption to workers’ tasks while wearing it.

The core hardware device measures no more than 46 mm × 23.5 mm × 13 mm.

Product Features

1. Precise Location Tracking: Utilizes BeiDou satellite positioning combined with Wi-Fi positioning technology

2. Long Battery Life: Features a built-in high-performance battery (100 mA) that supports at least 150 data uploads,
ensuring long battery life and eliminating the need for frequent charging

3. User Management: Manages user information associated with the wristband:
Add, update, and delete user information.
Link users to departments.

4. Department Management: Enables general management of organizational departments within the platform:
Supports the creation, editing, and deletion of departments.
Configures departmental hierarchical structures. Supports multi-level nesting with a maximum depth of 10 levels.

5. Device Management: Manages the onboarding, data processing, and maintenance of wearable devices:
Device registration and authentication to ensure secure access to the platform; supports high-concurrency connections.
Can be scaled to over 1 million devices via hardware upgrades.
Real-time parsing and storage of device location data.
Supports remote (OTA) device firmware upgrades and version management.
Monitors device status (battery level, connection status, error logs, etc.).
Device data is stored for 7 days.

6. Historical Trajectories: View individuals’ activity trajectories within a specified time period:
Displays individuals’ movement trajectories on a map interface.
Supports custom time ranges.
Supports real-time updates of device trajectories.
Trajectory data is stored for 7 days.

7. Geofence Data Statistics: Analyze and report on user interactions with geofences:
Records timestamps of users entering and exiting geofences.
Tracks the cumulative time users spend within geofences.
Data can be exported (in XLSX format).

8. Geofencing: Configure and manage virtual geofences, and associate them with personnel:
Supports custom geofences.
Associate geofences with specific individuals or groups; a single geofence supports up to 10,000 users.
Provides real-time alerts for geofence entry and exit events.
Geofence alert data is stored for 7 days.
