RTK+UWB positioning electronic badges + positioning helmets ensure the safe production of personnel in factories and mines, providing seamless indoor and outdoor personnel positioning without blind spots.

The factory director entered the dilution kettle for maintenance, and just one minute later, he collapsed inside the kettle. The team leader went in to rescue him, but also collapsed. Both died.

The surveillance footage showed that it took less than 60 seconds from the moment he entered the kettle to the moment he lost consciousness.

During these 60 seconds, if someone were to look at the surveillance screen, what would they see?

Nothing can be seen. Because the person is inside the kettle - indoors, enclosed, and without signal - the positioning system has already shown offline.

During these 60 seconds, the system displayed that the positioning was normal, but the person had already disappeared.

Upon reflection, there is one question that cannot be ignored:

If we could have located the factory director inside the kettle in real time and noticed his prolonged immobility, could we have detected it a minute earlier? Could we have prevented the team leader from blindly attempting a rescue?

But the reality is: traditional GPS positioning simply cannot function properly indoors. As soon as a person enters an indoor environment, the system may display offline status or location drift - this is not a device malfunction, but an objective limitation determined by the technical principle.

Workers wear electronic badges and positioning helmets as required and enter the work area. Management personnel only see "signal loss" or "position drift" on the monitoring screen - even though the personnel are actually in indoor corridors, underground utility tunnels, or signal-obstructed areas, the system displays them as being hundreds of meters away.

The issue of positioning distortion and loss of contact in blind areas is a common challenge in safety management across various operational scenarios, directly affecting personnel safety control and emergency response efficiency.

Due to the limitations of on-site conditions, such difficulties are prevalent in the industry:

The operation areas are scattered, and there is severe signal obstruction in steel structure factories, underground spaces, and multi-story buildings, making it easy for positioning signals to be interrupted. Traditional GPS becomes ineffective indoors, and once personnel enter these areas, their positioning is lost, creating large monitoring blind spots. It is impossible to track personnel engaged in scattered operations. The inspection routes are long and the operation areas are scattered, making it difficult for management personnel to grasp the real-time distribution of all personnel. This results in slow response to emergencies, inability to quickly and accurately locate personnel positions during emergencies, and waste of critical rescue time. This can easily lead to the most dangerous chain:

Personnel enter the indoor blind zone → The system displays distorted location or goes offline → Unable to quickly locate in emergency situations → Delayed rescue response

In accordance with relevant industry safety management requirements, full coverage and traceability of personnel positioning are the basic bottom line for enterprise safety control. "Missing" due to positioning blind spots not only increases personnel safety risks, but also potentially exposes enterprises to compliance penalties and accountability investigations. Addressing positioning blind spots has become a rigid demand in the industry.

1. Real pain points in the industry: Traditional positioning cannot solve the problem of "losing track of things indoors"

The current positioning methods relied on on-site, in real and complex operational environments, all exhibit significant shortcomings, making it difficult to achieve precise positioning across all scenarios:

method

limitation

GPS-located electronic work badge + GPS-located safety helmet

The indoor signal is weak, leading to significant positioning drift errors, and even direct offline indications, which cannot meet the requirements of indoor positioning

Manual roll-call

The system lacks real-time performance, enabling only post-event investigation. It cannot dynamically track personnel locations and is unable to respond to emergency situations

video surveillance

The coverage is limited, and there are natural blind spots in areas such as underground utility tunnels and equipment corners, resulting in low retrieval and tracing efficiency

Walkie-talkie call

Relying on personnel to report proactively, there may be situations in emergencies where personnel are unable to operate or respond, resulting in insufficient communication reliability

The fundamental shortcomings are immediately apparent:

The existing positioning solution only addresses "visibility outdoors" but fails to achieve "integrated precise positioning for both indoors and outdoors". While it appears to meet safety protection requirements, it actually leaves a fatal management blind spot. If overlooked, compliance risks will be attributed to it, which is a common hidden danger for many enterprises.

II. Technical Solution: Indoor and outdoor integrated positioning, seamless switching without missing positions

To overcome the challenge of "indoor and outdoor positioning blind spots", there is a clear and mature solution direction in the industry:

By adopting a fusion mode of "outdoor Beidou RTK high-precision positioning + indoor Bluetooth positioning", seamless switching between indoor and outdoor positioning is achieved. Location information is reported to the management platform in real-time, ensuring that personnel can be accurately located and tracked in real-time, whether they are indoors or outdoors.

A mature technology path verified by industry practice, adaptable to various complex operational scenarios:

Outdoor positioning: Single-Beidou dual-frequency RTK positioning, with sub-meter accuracy (30cm±1PPM), stable positioning and no drift in open environments. Indoor positioning: Bluetooth positioning, effectively covering indoor corridors, underground utility tunnels, and other areas with weak signals, eliminating indoor blind spots. Smart switching: Automatically switches positioning modes according to the operating environment, without manual intervention, ensuring seamless switching and uninterrupted positioning. Real-time reporting: 4G Cat1 network-wide transmission, synchronously pushing personnel location, status, and time to the management platform, achieving dynamic visual control of all personnel. This completely changes the traditional management mode of "people seeking the system and passive investigation" to "the system actively tracking and providing real-time alerts", significantly improving safety management efficiency and reducing control risks.

III. Compliant and practical product: Beidou high-precision positioning electronic work badge + positioning safety helmet BD30

Addressing the industry's persistent pain point of "blind spots and loss of contact" in indoor and outdoor personnel positioning, and in accordance with industry safety management compliance requirements, U-View Technology has developed the BD30 Beidou high-precision positioning electronic badge + positioning safety helmet. This provides a practical, verifiable, and comprehensive positioning solution that is suitable for various work scenarios, filling the management gap where "people are on site but cannot be found".

VI. Consensus on Safety Management

Technology cannot replace management, but it can effectively eliminate management blind spots and enhance management efficiency.

The true safety bottom line for indoor and outdoor personnel management is: not only to achieve personnel positioning, but also to ensure real-time traceability and traceability across all indoor and outdoor scenarios.

For every safety manager:

The controllable position that can be seen, and the blind area that cannot be seen, are the most fatal.

More importantly:

More importantly, positioning electronic badges and safety helmets, rather than just "for show", can address the shortcomings in indoor blind spots. This is not only to safeguard personnel safety and avoid compliance risks, but also a responsibility of every manager.
