On September 28, China’s first simulation system for training and automatic evaluation of heavy-haul railway dispatching, co-developed by Shuohuang Railway and Southwest Jiaotong University, passed the acceptance test and was officially put into use in the dispatch and command center.

This simulation training system has introduced the brain learning mechanism into dispatch training for the first time, and constructed an integrated simulation training framework involving “teaching, training, test and analysis”, which aims to help dispatchers gradually accumulate knowledge through cognition, understanding, mastery and application of the expertise. The system has realized the automation of training and examination, and advanced the standardization of dispatch vocational training. As for the content of training and assessment, the system takes into full account the dispatch operation characteristics of Shuohuang Railway, such as steep slopes, the large number of bridges and tunnels, high running density of heavy-haul trains, difficulty in driving command and high requirements for emergency response. As it covers all basic operations of centralized control system and equipment for dispatch, the system incorporates emergency response for 20,000-ton heavy-haul trains under unexpected circumstances, such as abnormal driving, driving equipment failure, construction organization and disastrous weather, and helps effectively improve dispatchers’ skills through panoramic simulation training.

Meanwhile, the system has made “four innovative breakthroughs”. First, the “immersive” 1:1 full simulation development mode was adopted for the first time, and the data of stations and lines are completely consistent with actual situations, which can realize seamless connection between simulated training and real dispatch stations and enable the trainees to make their skills ready to use. Second, artificial intelligence was adopted for the first time to realize unmanned automation for the key links of “training and assessment”. Third, for the first time, the virtual anthropomorphic phantom technology was adopted to exercise coordination between dispatching center and virtual drivers, directors on duty, and workers on duty at the station. Fourth, the modular scene editing mode was adopted for the first time to realize rapid and automatic editing of training scenes and content through spliced modules.

The simulation training has ousted the traditional training mode featuring “paper-and-pencil examination plus lecture classes,” which is helpful for dispatchers to truly understand and master all kinds of basic operations of the dispatch and central control system and comprehensively improve their response to emergencies.
