LoRa IoT Technology Positioning Watch

Location applications based on LoRa IoT technology feature low power consumption, long-distance transmission, and precise positioning, demonstrating significant advantages in multiple fields. Below are its main technical features and application scenarios:

I. Technical Features

Positioning Principles:

Triangulation: Utilizes multiple LoRa gateways to receive signals and calculates position using Time Difference of Arrival (TDOA).

Time of Flight (ToF) Ranging: Measures signal round-trip time with accuracy up to 2 meters.

Signal Strength (RSSI): Estimates distance through multi-base station signal strength and combines with trilateration for positioning.

System Advantages:

Communication Range: 2-5 km in urban areas, up to 15 km in suburban areas.

Ultra-Low Power Consumption: Sleep power consumption only 0.1μA, tag battery life over 3 years.

High Capacity: A single gateway supports up to 5000 tag connections.

II. Typical Application Scenarios

Addressing the challenge of managing and scheduling a large number of sanitation workers, the Smart Sanitation Personnel Location Card records daily work data and includes alarm management features, facilitating supervision and standardized operations. This not only significantly enhances management efficiency and work productivity but also greatly reduces operational costs in sanitation management.

Product Features

Smart Location Badge Introduction: This product addresses the difficulty of personnel location management by enabling location tracking through simple operations. It includes features such as "real-time positioning," "electronic fencing," "trajectory playback," and "report generation." Through platform operations (supporting mobile apps, computers, web pages, and WeChat official accounts), it allows direct navigation to personnel locations, supports remote 3D real-world maps, cross-region electronic fencing, and more, making it an essential technological innovation for intelligent personnel management.

I. Device Startup

1) The device is powered on by default! If the battery is low, the indicator light may not illuminate or the red light may flash continuously. In this case, connect the charger to charge the device.

2) A flashing red light indicates charging is in progress. Charging typically takes 2-3 hours. When the charging indicator remains steadily lit, it indicates the device is fully charged. Alternatively, check the "Battery" status in the client's "Status Bar" to see the charging percentage; 100% indicates a full charge.

II. Device Shutdown: To prevent accidental operation, the device does not support manual shutdown.

III. Charging Method

1. Insert one end of the USB cable into the charger and the smaller end into the charging port on the left side of the device.

2. A flashing red light indicates charging.

3. A steady red light indicates the device is fully charged. It is recommended to charge for an additional half hour at this point.

IV. Indicator Light Display

During normal operation, a blue light indicates GPS and BeiDou satellite data signals, a green light indicates LBS data signals, and a flashing red light indicates low battery, requiring prompt charging.

V. Product Configuration

1. Built-in 800mAh lithium battery.

Livestock Management:

Cattle and sheep location tags support electronic fencing and stray alarm functions.
