UWB Substation Application Case

Function Point

Function Description

Real-time Personnel Positioning

Positioning accuracy of 0.3-1 meter, enabling real-time positioning management of substation maintenance personnel, viewing their real-time locations, distribution areas, etc., to grasp personnel dynamics anytime, anywhere.

Historical Trajectory Query

Visual traceability of maintenance operations. By replaying historical trajectories, it organically combines spatiotemporal information with work content and video images.

Personnel Roll Call

Can retrieve activity information of personnel within a specified area.

Fall Detection for Elevated Work

For high-altitude and climbing work within the substation, checks if working conditions meet requirements. Electronic fences below the work area prohibit non-workers from walking or lingering. Checks for nearby overhead power lines or equipment, ensuring sufficient safe distance from live equipment is maintained. In some cases, power must be cut off before work. In case of slips or falls during high-altitude work, fall alarms are sent to the control center. Workers can also press the SOS alarm button to actively call for help.

One-Key SOS

The card has a built-in SOS button. Pressing for 3 seconds triggers audible and visual alarms on the system platform.

Electronic Fencing

Sets virtual work fences based on maintenance tasks to supervise the work scope and duration of maintenance personnel. Links personnel tasks with time and space. Sets alarm fences for live operational areas during maintenance. If unauthorized personnel enter, alarm information is triggered on both the supervision platform and the tags worn by personnel.

Inspection Management

Uses drawing tools to create circular, polygonal, or rectangular fence areas, configures basic area information, inspection plans, generates reports, etc.

Area Personnel Statistics

Real-time statistics of personnel counts in various areas, e.g., switchgear room, GIS room, main transformer room, control room, outdoors, etc.

Asset Positioning

Monitors fixed assets by attaching asset positioning tags.

Alarm Record Information Management

Uses icon-based visual display for different types of alarm information.

Data Statistics & Query

Displays statistical counts of alarms, provides query and printing of annual, monthly, and daily alarm statistics.

Positioning Information Heatmap

Statistically analyzes personnel and vehicle distribution data on a positioning map, generating and displaying a heatmap.

Location Tracking

Queries a snapshot of personnel positioning information distribution at a specific moment.

Visitor Management System

Registers external personnel, allows adding, modifying, deleting, and handles card issuance and collection for visitors.

Video Linkage

Integrates the UWB positioning system with the substation video surveillance system. Once an alarm occurs in an area (e.g., strangers at entrances/exits, personnel entering unauthorized areas, approaching hazards, SOS calls), the system immediately pops up live surveillance footage and takes photos to record the situation, providing basis for efficient decision-making.

Hardware Status Management

Queries working status information of hardware like positioning base stations and beacons, displays their map locations for convenient future maintenance.

Positioning System Supports Multiple Map Formats

Oblique photography, Hummingbird Cloud Map, Gaode Map, 3D modeling, 2D maps.
