Distributed Network Broadcasting System for Construction Sites

I. System Overview

In traditional construction site management, information delivery often relies on walkie‑talkies, manual shouting, or WeChat group messages—resulting in low efficiency, rapid signal decay, slow response, and persistently high safety risks and communication costs. The GENDE Distributed Broadcasting System, with its ultra‑simple deployment concept of “no server, no IP configuration, just power on and connect to the network,” enables instant command across the entire construction site, completely breaking down information silos.

II. Core Pain Points and Scenario Requirements for Construction Sites

(I) Four Core Application Scenarios

1. Safety Intervention and Violation Deterrence

Traditional methods rely on walkie‑talkie calls or on‑site personnel to intervene, taking 5–10 minutes. Hazards are not addressed in a timely manner, leading to high safety risks. There is an urgent need for “detect and announce, one‑key intervention.”

2. Emergency Evacuation and Incident Response

In emergencies, traditional methods rely on manual shouting and WeChat group messages. Information decays quickly, workers have no clear evacuation direction, and emergency command fails. There is an urgent need for one‑key broadcasting across the entire site for rapid, full‑scale evacuation.

3. Intelligent Dispatch of Tower Cranes and Transport

Traditional methods rely on hand signals and one‑to‑one communication, resulting in low dispatch efficiency, long waiting times for hoisting, and project delays. There is an urgent need for instructions to reach the site directly, improving dispatch efficiency.

4. Cross‑Zone Coordination Management on Large Sites

Notifications across different sections or zones are relayed through multiple layers, creating information silos and management disconnects. There is an urgent need for seamless networking across multiple sections, enabling one central control center to manage multiple sites.

(II) Inherent Pain Points of Traditional Systems

Traditional broadcasting systems rely on servers, requiring complex IP debugging and software licensing. Expansion is difficult, operation is cumbersome, and deployment cycles are long, making them unable to adapt to the ever‑changing layouts and flexible networking needs of construction sites.

III. Core Value of the GENDE Solution

Leveraging an innovative distributed architecture, the solution optimizes the broadcasting experience on construction sites in all aspects, reduces costs, improves efficiency, and enhances management with data‑driven metrics:

Four Core Advantages

1. Easy Deployment – No server, no IP configuration. Just power on and connect to the network – ready to use.

2. Simple Operation – Human‑centered design, zero learning curve. No professional training required.

3. Reliable Emergency Response – Emergency broadcasts are given priority, ensuring accurate delivery of critical information.

4. Flexible Expansion – Distributed networking allows free addition or removal of devices, adapting to the dynamic needs of construction sites.

IV. Core Equipment and Scenario Applications

(I) Indoor Network Speaker (NC‑BG01)

Applicable Scenarios: Office areas and living zones such as project headquarters, dormitories, meeting rooms, indoor passageways, etc.

Product Features: Reinforced wall‑mount design, adaptable to prefabricated building walls, vibration‑resistant, anti‑detachment, clear vocal reproduction.

Applications: Safety morning meetings, work briefings, schedule announcements, safety reminders, evacuation guidance, zone broadcasting.

(II) Outdoor Network Sound Column (NC‑YS60)

Applicable Scenarios: Open areas such as deep excavation pits, tower crane zones, material storage yards, outdoor work surfaces, etc.

Product Features: IP65 three‑proof design – dustproof, rainproof, and UV‑resistant, adapting to harsh construction environments, long‑distance sound transmission.

Applications: Safety alerts, violation warnings, tower crane dispatching, material notifications, danger warnings, noise‑reduction broadcasting to minimize disturbance to surrounding areas.

V. Five Core Functions of the System

1、Multi‑Mode Intelligent Broadcast Announcements

• Targeted Announcements – In the monitoring room, see and shout. Linked with surveillance cameras. Zone or all‑call broadcasting at will, enabling real‑time violation deterrence.

• Mobile Announcements – Handheld wireless microphone for mobile patrols. Untethered command, delivering notifications instantly.

• Portable Announcements – Wearable walkie‑talkie, allowing patrol and broadcast simultaneously. Announce anywhere, anytime, with cross‑zone second‑level propagation.

Applicable Scenarios: Safety patrols, violation deterrence, on‑site coordination, emergency command, pre‑shift safety training.

2、Scheduled Announcements and Background Music

Supports MP3 scheduled playback, one‑key broadcast control via mobile app, external audio source input, and emergency insertion function. Unattended operation – automatically plays schedule announcements, replacing manual bells. Balances daily management and emergency needs with clear sound quality, delivering instructions directly.

3、Smart Linkage with Safety Monitoring System

Seamlessly integrates with the site’s safety monitoring system: When a hazard is detected on surveillance, one‑key broadcast intervention is triggered and executed within 3 seconds. In case of an emergency, alerts are automatically triggered, notifying the entire site in seconds. Evacuation instructions can be initiated with one key, reaching all personnel within 10 seconds – eliminating the need for step‑by‑step relaying.

VI. System Architecture and Standard Configuration

(I) System Composition

Adopts a distributed network architecture, leveraging the existing local area network (LAN). The system includes: network microphone, wireless mobile microphone, network speakers, network sound columns, safety monitoring linkage terminal, and other equipment.

(II) Typical On‑Site Configuration

1. Monitoring Center – Network microphone, supporting zone paging and full‑site control.

2. Living Area – NC‑BG01 wall‑mount network speakers, clear vocal reproduction, zone broadcasting.

3. Work Area / Tower Crane Zone / Deep Excavation Pit Area – NC‑YS60 outdoor three‑proof sound columns, precise sound transmission, resistant to harsh environments.

(III) Control Equipment

• Network Microphone – Fixed station, one‑key zone announcements, simple and easy to use.

• Wireless Microphone – Mobile patrol, emergency response, unrestricted by site layout.

• Safety Monitoring Linkage Terminal – Connects with surveillance system, automatic alert triggering.

• MP3 Player – Scheduled playback, unattended operation, adapting to site schedule.

VII. Conclusion

The GENDE Distributed Network Broadcasting System focuses on being simple, efficient, and reliable, directly addressing the pain points of traditional construction site broadcasting: difficult deployment, high cost, slow response, and poor scalability.

No server, no IP configuration, plug‑and‑play. It supports daily pre‑shift safety training, schedule announcements, on‑site coordination, and zone management, while also enhancing safety intervention, emergency evacuation, and cross‑zone coordination capabilities. The system features low equipment cost, simple operation and maintenance, and strong scalability, making it suitable for upgrading various smart construction sites.

In the future, the system will continue to empower the construction of smart construction sites, improve site‑level intelligent management, strengthen the safety defense line for construction, simplify on‑site control processes, and help sites reduce costs, increase efficiency, accelerate progress, and ensure quality. It is the preferred solution for upgrading broadcasting systems on smart construction sites.
