Hmcomm adopted Braveridge’s 2.4 GHz ultra-thin antenna as the basic configuration and is advancing the practical implementation of drive-by infrastructure monitoring using data collected from moving vehicles. Performance validation in actual field environments will follow.
Hmcomm announced plans to jointly advance the enhancement of wireless communications for infrastructure monitoring and validation using actual equipment with Braveridge by adopting Braveridge’s 2.4 GHz ultra-thin antenna designed for installation on metal surfaces as the basic configuration for its drive-by system. The antenna is approximately 1 mm thick and designed for installation on metal surfaces, with an example of installation on a manhole cover also disclosed.
The drive-by system collects sensor data wirelessly, using BLE and other technologies, as a vehicle travels near the target infrastructure, then analyses the data with AI in the cloud to identify locations with potential anomalies. It aims to improve the efficiency of broad-area infrastructure monitoring without requiring a permanent communications line for each facility.
The Company is conducting risk analysis combining leak detection and AI anomaly detection in a demonstration project in the water-supply sector in Moriyama City. At an interim briefing, it announced the results of communications validation for the drive-by system and plans for future demonstrations. Going forward, communications performance will be validated in multiple actual field environments.
Braveridge’s antenna is designed to maintain wireless characteristics on metal surfaces and is considered promising even in simulated environments using steel covers. Going forward, the antenna will be used to optimise communications conditions in infrastructure environments and validate the conditions for data acquisition in actual field environments.
