Aspinity Delivers Always-On, AI-Lynx AI-Powered Vehicle Surveillance System with Silicon Labs’ Low Power Bluetooth and Wi-Fi Devices

|

Automotive security systems and dashcam monitoring technology have been around for decades. However, dashcam monitoring typically only focuses on recording driver behavior or capturing video footage when sudden motion or impact is detected, such as a collision, while the vehicle is being driven. Very few solutions focus on protecting a vehicle while it’s parked or unattended, and those that do, often lack the event detection accuracy and battery life to provide quick, meaningful insights that drivers need to take action. Collecting and processing data can quickly drain a car’s battery when parked for multiple days or weeks. Add to that, the unnecessary data that is captured when the system mistakenly interprets another car’s alarm, a large truck driving by, or even a heavy wind as a legitimate security event. Knowing when a threat is real, such as when a vehicle is touched, scratched, or broken into, and notifying drivers so they can activate an alarm or other prevention measures is essential to fending off vandalism or theft.

Aspinity is the leader in near-zero power AI solutions and their vehicle surveillance solution delivers always-on security for parked vehicles without impacting a vehicle’s battery. The system leverages a GWY plus multiple Tags placed around the vehicle, that detect audio, vibration and presence events and connect wirelessly into a main gateway, which also operates as a central hub for collecting all sensor data and communicating real-time alerts to a vehicle owner via a mobile application. By using analog machine learning and sensor fusion, the AML100 Tags and Gateway are able to continuously capture and process raw audio, vibration and radar signals at low power levels and use Aspinity’s automotive security event machine learning model to determine if a relevant threat has occurred. When an important security event is detected, the AML100 wakes up the Silicon Labs communication devices to take the next step. As a result of Aspinity’s ultra-low power inferencing and Silicon Lab’s ultra-low power communications, Aspinity’s vehicle security solution is highly accurate at identifying security events without draining the vehicle’s battery, delivering peace of mind and always-on automotive protection.

挑战

Aspinity wanted to develop an always-on car security solution for parked or unattended vehicles with the highest level of accuracy and lowest level of power consumption possible. Doing so required continuous sensing and monitoring that didn’t impact the vehicle’s battery.

解决方案

The combination of the AML100 machine learning processing with automotive security event detection ML models from Aspinity, with the EFR32BG27 Series 2 Bluetooth® Wireless SoC and the SiWx917M Wi-Fi® SoC modules from Silicon Labs met the critical low-power requirements for a car surveillance solution developed on Aspinity’s IoT Enablement Platform.

结果

By selecting Silicon Labs’ Bluetooth BG27 SoC and 917 Wi-Fi SoC for inclusion on its IoT Enablement Platform, which includes a fully connected AML100 Gateway and multiple AML100 multisensor Bluetooth tags, Aspinity is now delivering the AI-Lynx AI-powered vehicle surveillance solution for unmatched protection of unattended vehicles of all types.

Parked Vehicle Surveillance System Requires Low Power and High Accuracy

Power is particularly important in automotive applications because there are multiple sensors throughout a vehicle. The power demand becomes even more amplified when trying to protect a vehicle with a trailer or large commercial vehicles such as trucks or freight carriers. Adding to the complexity, continuous sensing is particularly challenging when a vehicle is parked since data collection and processing must happen without depleting the battery.

When Aspinity began development of their vehicle surveillance system for parked vehicles, they knew it had to be low power and accurate in order to deliver the best performance and results to end-users. Their proprietary analog machine learning algorithms enable data processing at the edge, consuming only the lowest levels of power. However, the solution also required low-power, real-time communication when security events occurred.

The gateway was designed to be flexible and needed to be able to receive Bluetooth information from all Tags when security events were detected and then know what to do with that information by either sending it to the cloud or to a user’s mobile device for immediate action such as activating an alarm or lights. Similarly, the Tags provide ongoing vehicle monitoring and need to be able to quickly identify a security event and send that data to the main communication hub. The team knew they needed a wireless solution that matched their near-zero power requirements for both the smart tags and the in-vehicle gateway, but also one that delivered reliable connectivity.

Choosing a Wireless System Optimized for Battery-Powered IoT Devices

After evaluating multiple options, Aspinity chose Silicon Labs’ BG27 Bluetooth LE SoC for use in their AML100 Tags along with the SiWx917M Wi-Fi® 6 plus Bluetooth® Low Energy LE 5.4 SoCs for the AML100 Gateway. As Silicon Labs’ lowest-power, most energy-efficient Bluetooth LE device, the EFR32BG27 SoC module was the ideal choice for providing low transmit and receive power and extended battery life needed to enable the always-on sensing capabilities in Aspinity’s smart tags. The SiWx917M SoC helps bring the AML100 Gateway’s communication protocols to life as it’s optimized for ultra-low power IoT wireless devices using Wi-Fi®, Bluetooth, Matter, and IP networking for secure cloud connectivity. The team liked that it was well-established and offered a “one-stop shop” wireless system in a compact chip – being able to both communicate to the smart tags and gather threat detection data via Bluetooth, as well as being able to connect to the Internet to send data to the cloud or to users via the mobile app.

Leveraging Silicon Labs’ wireless SoC and Bluetooth modules, Aspinity’s vehicle surveillance system can accurately assess security threats and optimize overall system performance and power consumption. Aspinity gives end-users uninterrupted monitoring and peace of mind knowing that their vehicles and cargo are protected when parked.
