Impact Detection System

Ubiquity Through Economy™

Giving your Critical Road Safety Devices a voice. Monitor, Detect, Report, and Manage on a single platform.

Monitor Your Assets

Multiple assets at no additional cost! pi-lit®’s radio mesh network allows many sensors to report through a single cellular or fiber-cable gateway. Many-to-one: that’s our secret sauce!

Critical Safety Devices to Monitor:

• Crash Cushions & end treatments
• Guardrails and cable barriers
• Signs (Gore, Stop, Yield, Chevron, Etc.)
• Railroad Crossing Gates
• Work zone delineators (barrels, cones, message boards)

Impact Detection Examples

• Rude Awakening: Major Hit and Run
• Unreported Nuisance Impact
• Attenuator Inspection Gone Wrong
• Cable Barrier Impact Detection at Distance

Detect Your Assets

Real-time alerts via text message or email when a road safety device is impacted. Nuisance impacts that otherwise would go unnoticed are now reported in real-time to ensure immediate inspection and repair.

Manage Your Assets

Manage inspection, maintenance, and repairs from the dashboard. Capture critical asset tracking and manufacturer information for quick recall identification, spare parts required following impact, etc. Automatically pushes the attenuator’s location and information to the dashboard where maintenance and management can view and monitor key assets.

Generate Your Reports

Generate reports of impact history by location and device. Data collection leads to useful information regarding comparative device performance, cost benefit by manufacturer, and safety analysis.

Features and Specifications

Impact Detection System

Pi-Lit uses one of two smart devices to monitor your crash cushions and barriers: The IDS Gateway and IDS Node. These are identical with one exception. The Gateway includes a cellular modem. When within range, many nodes can talk to a single Gateway leading to much lower cost deployment.

Gateway

Specifications

• 2.4GHz radio mesh network (not Bluetooth, not Wi-Fi, not Zigbee).
• Cellular network on ATT.  International coverage with ATT roaming partners.
• Range between Gateway and Node: unobstructed line-of-sight 150 meters (492 feet).
• Default Check-in frequency every 24-hours: Can be adjusted upon request.
• 4-year battery life.
• Low battery alert at 25%.  This is configurable by the customer on the Dashboard.
• 3 axis (X,Y,Z) accelerometer sensor onboard.
• Impact sensitivity set at 2500 milli-G’s.  This can be adjusted by the customer on the Dashboard.
• IP67 (dust and water protection).

Features

• Receive impact notifications within 60 seconds (email and/or text)
• Following impact, alert includes time stamp, Google Map location of device, photograph of device at time of initial deployment.
• Deployment takes 2 minutes.  No tools, brackets, putty, or modification of the safety device.
• Remote configuration of sensitivity (from your desktop).
• Daily health status report to your Dashboard.
• Review history of events at that physical site.

Node

Specifications

• 2.4GHz radio mesh network (not Bluetooth, not Wi-Fi, not Zigbee).
• Range between Gateway and Node: unobstructed line-of-sight 150 meters (492 feet).
• Default Check-in frequency every 24-hours: Can be adjusted upon request.
• 4-year battery life.
• Low battery alert at 25%.  This is configurable by the customer on the Dashboard.
• 3 axis (X,Y,Z) accelerometer sensor onboard

Features

• Receive impact notifications within 60 seconds (email and/or text)
• Following impact, alert includes time stamp, Google Map location of device, photograph of device at time of initial deployment.
• Deployment takes 2 minutes.  No tools, brackets, putty, or modification of the safety device.
• Review history of events at that physical site.

Our Technology

Our novel sequencing technology and IoT devices are based upon a network topology referred to as a “mesh”. In this network architecture all of the nodes (lamps, sensors, etc.) are equal – no coordinator or followers. It is a decentralized network, each node or device acts independently of others. Our breakthrough innovation in applying mesh networking to road safety technology has resulted in 20 granted patents and this number is growing.

Save Money

Whether crews are deployed to drive miles to inspect cable barriers, or your department relies upon “passive maybe” reporting, safety cannot rely on “maybe”. Crew time is expensive, vehicle miles are expensive, and liability resulting from failure to inspect is expensive. Or you can choose the smart, pennies-per-day alternative: pi-lit® Asset Impact Management System AIMS™.
