In the 12.7 square kilometers of Rongdong area in Rongcheng County, Baoding City, Xiongan New Area, Hebei Province, China Telecom invested and built the country’s first large-scale regional digital road with a total length of 153 kilometers, which has now entered the operation period.
In order to improve the efficiency of digital road operation and maintenance and promote the vigorous development of the low-altitude economy, China Telecom Digital City Technology Company innovatively combines digital road smart light poles with intelligent networked drones to create a “digital road + low-altitude” intelligent inspection application scenario, realizing all-weather dynamic monitoring of digital road infrastructure operation and maintenance, road traffic management and urban comprehensive governance.
Innovative application, new path for traffic inspection
This scenario makes full use of the roadside infrastructure that has been built on the digital road, and deploys drone cabins on smart light poles, which not only reduces the area occupied by the cabins and saves 30% of the cost of independent station construction, but also further expands the field of view of the monitoring screen, conducts high-precision inspections of road infrastructure, greening maintenance, lighting systems and key construction areas, and reduces the impact on ground personnel and vehicles. After testing and application, it only takes 15 minutes for drones to complete the inspection of 5 kilometers of digital roads, which is 60% lower than the cost of traditional vehicle inspections, achieving a “double reduction” in construction and operation costs.
The networked drones deployed on smart lamp poles can be remotely controlled based on 4G/5G networks, and use visual AI and large model technology to realize the automatic identification of various events such as digital road facility equipment operation and maintenance, traffic operation, etc.
Based on the low-altitude intelligent inspection service platform, drones can take off with one button, carry out automated flights according to preset routes, and automatically transmit the inspection images and automated identification results back to the low-altitude flight service command center.
The traditional manual inspection mode is upgraded, and the efficiency of digital road inspection is greatly improved by combining autonomous inspections with scheduled cruises. When problems are found during inspections, the command center integrates multi-source information from low-altitude and ground monitoring to generate disposal suggestions, so as to realize timely discovery and rapid disposal of events.
