Behind the seamless flow of automated logistics, AGVs (Automated Guided Vehicles) function as tireless steel lifeblood, navigating factories and warehouses. Ensuring their safe, reliable operation—especially in complex human-robot environments—demands intelligent warning systems that serve as both safety essentials and communication bridges. Among these, three-color warning lights and audible-visual alarms (including buzzers and motion music modules) play pivotal roles.

Core Warning Devices Explained

1.Three-Color Warning Lights: Visual Status Language

Function: Instantly communicates AGV status/intent via universal color signals:

Red: Emergency stop, critical failure (highest priority).

Yellow: Deceleration, path adjustment, standby (caution advised).

Green: Normal operation, safe passage (all-clear signal).

Advantages: Intuitive messaging, high visibility (even in complex lighting), globally recognized safety coding.

2.Audible-Visual Alarms: Dual-Sense Alerting

Function: Combines bright flashing lights with high-decibel sounds for urgent alerts in noisy/low-visibility areas.

Key Components:

Buzzers: Sharp, standardized tones (e.g., “beep-beep-beep”) for immediate warnings:

Emergency stops

Obstacle proximity

Critical failures

Motion Music Modules: Programmable melodic tones for non-critical alerts:

Background travel notices (“Caution, vehicle approaching”)

Task completion alerts

Low-priority reminders

Advantages: Unmissable alerts (sound + light synergy), broad coverage, human-friendly audio profiles.

Scientific Selection: Matching Solutions to Your AGV

Choosing warning devices requires balancing safety, efficiency, and environmental experience. Key selection dimensions:

1.Scenario & Regulatory Compliance (Priority)

Noise Levels:

Loud workshops: ≥120dB alarms

Quiet labs: Motion music modules

Human-Robot Density:

Mixed zones: Three-color lights + buzzers (mandatory)

Isolated routes: Simplified setups

Safety Standards:

Mandatory compliance with EN ISO 13849, ANSI/ITSDF B56.5 (governing colors, sound patterns, brightness, volume).

2.Core Performance Alignment

Voltage & Power: Match AGV power systems (e.g., 24V/48V DC) and minimize drain on battery life.

IP Rating:

Indoor/dry: IP54

Dusty/humid: IP65+

Outdoor/harsh: IP67/IP69K

Visibility/Audibility:

Lights: High brightness (lumens/candela), wide viewing angles.

Alarms: Clear dB @ distance, distinct tones (buzzers) or melodies (music modules).

Mounting: Fit AGV chassis space (top/sides) and interface (screw holes/clips).

Beyond Accessories: Safety System Nerve Endpoints

Three-color lights and audible-visual alarms are not mere “add-ons”—they form the nervous system of AGV safety, enabling efficient human-robot collaboration. Understanding your operational challenges is key to effective investment.
