Responsible for dispatching work orders to receive customer feedback, deliver company equipment, and provide online equipment support. Conduct regular satisfaction follow-ups with users to achieve a closed-loop service.

Provide full lifecycle management and maintenance for online operating equipment.

By equipping with advanced instruments and meters, detection platforms, and professional maintenance teams, we can quickly respond to customers' repair requests, simulate scenarios, quickly locate faults, and provide effective solutions.

The company has established a railway GSM-R/5G-R laboratory. The laboratory uses two independent 2M E1 data lines to achieve direct connection with the operation and maintenance center of the National Railway Group. Through in-depth analysis of the causes of faults and simulation of the repair process, it solves the offline simulation, training, testing experiments of the existing core networks of 18 railway bureaus, as well as the reproduction of faults in the current railway network, thereby improving the efficiency of fault detection and repair.
