This application proposes a configuration system and method for distributed power locomotives. The system includes an operation and display module for sending vehicle data of the distributed power locomotives to a central control module; sensors for measuring the weight of the dump trucks and the real-time tilt angle of the distributed power locomotives; a data acquisition module for collecting the weight and real-time tilt angle of the dump trucks; and a central control module for determining the required number of powered dump trucks and the required number of drive mechanisms based on the vehicle data, the weight of the dump trucks, and the real-time tilt angle, and configuring the distributed power locomotives based on the number of powered dump trucks and the number of drive mechanisms. The technical solution proposed in this application can quickly and accurately calculate the required number of powered dump trucks and the required number of drive mechanisms under the current construction environment, and can also flexibly group them based on the required number.

The invention provides a low earth orbit satellite communication and navigation integrated waveform design method based on downlink rate splitting multiple access. According to the method, a communication and navigation integrated system model based on a low-earth-orbit satellite constellation is established for a low-earth-orbit satellite internet scene in combination with a frequency spectrum sharing technology, communication and navigation positioning services are simultaneously provided for users by a group of satellites, and the utilization rate of frequency-earth-orbit resources is improved. According to the method, good self-correlation and cross-correlation characteristics of the ZC sequence are utilized, the ZC sequence serves as a positioning signal to be subjected to same-frequency-band power domain superposition with a communication signal, and accurate positioning can still be achieved even under the condition that the signal-to-noise ratio is extremely low. According to the method, the frequency track efficiency and the access density of the system are improved, and meanwhile, the complexity is low.
