1.One click self inspection

The mobile intelligent inspection terminal business system is integrated with unmanned aerial vehicle autonomous inspection micro applications, automatically obtaining inspection tasks and inspection routes. Operators can quickly start inspections with one click at the work site. After the inspection is completed, the intelligent terminal automatically completes data archiving, supports online or offline feedback, and can also perform lossless compression on the returned images. Supports single machine inspection mode, relay inspection mode, and multi-level inspection mode.

2.Remote monitoring

Mobile intelligent inspection terminal support4GThe remote live broadcast of real-time drone images and remote monitoring of real-time locations are achieved through feedback and lossless video compression, which facilitates remote management and command of drone inspection operations.

3.Intelligent calibration of navigation points for distribution towers

Distribution line towers are generally planned for routes through waypoint marking. The mobile intelligent inspection terminal has a built-in business system based on tower recognition algorithm, which can automatically perform intelligent waypoint calibration on a certain section of distribution line towers, reducing the complexity of waypoint planning through manual teaching and lowering the technical requirements for operators.

4.Intelligent collection and verification of tower ledger

The mobile intelligent inspection terminal is equipped with a built-in business system to connect and obtain the tower foundation ledger. At the same time, based on the tower recognition algorithm, it automatically collects tower information of transmission and distribution lines, including tower type, latitude and longitude, and height. The collected information is compared with the existing information in the ledger to see if it is consistent, and can be manually reviewed to update the ledger data.

5.Data archiving

After the drone inspection operation, the collected data is sorted and archived, mainly including: associating inspection images with towers or equipment, automatically naming images as inspection objects, classifying images by defect types, and classifying images by task operations.
