1. Overall Objectives

This solution targets multiple scenarios including industrial plants, smart parks, underground utility tunnels and commercial buildings, to build an indoor personnel positioning system featuring ‌high precision, full coverage, strong linkage and excellent scalability‌. It delivers a positioning accuracy of 10-30cm in core control areas and 1-5m in general coverage zones, with a global signal blind zone ratio below 0.1%. The system covers four core functions: real-time personnel tracking, electronic fence alarming, full trajectory tracing and emergency linkage dispatching. It can seamlessly connect to existing access control, security and video surveillance systems, enabling the management team to improve the response speed for personnel safety incidents by 80% and achieve an accuracy rate of 99% for violation identification. It fully replaces the extensive management mode of traditional manual patrol and access registration, and realizes the digitalized and refined closed-loop management of personnel control.

2. Core Design Principles

‌Technology Adaptation Principle‌: Avoid relying on a single positioning technology, select solutions based on the risk level of scenarios. Use UWB ultra-wideband in high-risk core areas to ensure centimeter-level accuracy, deploy Bluetooth AOA in general office/public areas to achieve low-cost coverage, and reuse existing Wi-Fi networks in old renovation scenarios to build basic positioning capabilities.
‌Lightweight Deployment Principle‌: Maximize the use of existing network infrastructure in the site, reduce wiring construction, compress the overall deployment period to 60% of the traditional pure UWB solution, and minimize the impact of construction on normal production and operation.
‌Safety Compliance Principle‌: All hardware equipment in high-risk scenarios meets explosion-proof, waterproof and dust-proof certifications. All data transmission is fully encrypted, complying with relevant laws and regulations on work safety and data security.
‌Open Scalability Principle‌: The platform reserves standard API interfaces, supports subsequent expansion functions such as asset positioning, vehicle scheduling and digital twin, and adapts to business growth demands in the next 3-5 years.

3. Technical Architecture and Selection Configuration

The whole system adopts a four-layer full-link architecture to ensure stable and reliable positioning performance in complex environments:

‌Perception Layer‌: Deploy hardware in layers according to scenarios
‌Transmission Layer‌: Adopt 4G/5G and LoRa multi-redundant transmission channels to avoid data packet loss caused by metal occlusion and electromagnetic interference, and control positioning data backhaul delay within 100ms.
‌Positioning Solution Layer‌: Equipped with a self-developed multi-mode fusion positioning engine, integrating TDOA (Time Difference of Arrival) and TOF (Time of Flight) ranging algorithms, combined with the indoor space geometric topology model to automatically correct multipath interference and signal drift errors, outputting accurate personnel position coordinates at millisecond level.
‌Application Layer‌: Build a visual management and control platform that supports multi-terminal access on PC, tablet and monitoring large screens, with full-function management modules built in.

4. Core Function Modules

‌Real-time Position Monitoring‌: Dynamically display the real-time positions of all online personnel on the electronic map, support filtering by department, post and permission, and accurately show the floor, room and specific area where the personnel are located.
‌Intelligent Electronic Fence‌: Customize multi-level electronic fences, set no-entry fences for high-risk areas, off-post overtime fences for on-duty posts, and stay overtime fences for limited open areas. Once violations are triggered, the platform immediately pops up an alarm and synchronously pushes information to the corresponding manager's mobile terminal.
‌Trajectory Backtracking and Analysis‌: Support full playback of the action trajectory of any personnel in any time period. Trajectory data is stored locally for no less than 12 months, meeting the compliance audit requirements of work safety. It can automatically count core operation data such as personnel patrol arrival rate and post stay duration.
‌One-click Emergency Dispatch‌: The positioning tag integrates an SOS one-click alarm button. When personnel encounter sudden danger, they can trigger the alarm with one click. The platform automatically uploads the precise position of the personnel, and links the surrounding surveillance cameras to automatically call up the corresponding footage, assisting managers to quickly carry out emergency rescue.
‌Multi-system Linkage Docking‌: Provide standard HTTP/SDK interfaces, seamlessly connect with existing access control, security and video surveillance systems of the enterprise, break data silos, and realize the full-process automatic management of "positioning - alarm - video linkage - disposal".
‌Passenger Flow Thermal Analysis‌: For public places such as shopping malls and exhibition halls, automatically generate regional personnel thermal maps, dynamically perceive passenger flow density, and automatically trigger crowding alarms when the number of people in the area exceeds the threshold, assisting managers to carry out passenger flow diversion.
