Description

Miniature Train Personal Simulator {Miniature Model of the Personal Type Simulator for the Electric Multiple Unit}

The present invention relates to a personal simulator for miniaturized electric trains.

Train driving training in the past was carried out by a guide engineer riding with a novice driver who had completed theoretical training on an actual route carrying a passenger. This training method not only takes a lot of time to train engineers, but also has problems such as the risk of accidents and the increase in cost due to the delay in training time. With the recent development of science and technology, like other means of transportation, train driver's license education institutions have introduced a train simulator using dynamics modeling for train driving. This training machine was introduced to improve proficiency for new and incumbent railway engineers in accordance with simulated track conditions and driving diamonds. Domestic railroad vehicle simulation training machines are classified into a total of 6 types, and are essential equipment for obtaining a new license in accordance with the Enforcement Decree of the Railroad Safety Act. However, this equipment is very expensive due to the hardware similar to the actual vehicle cab environment and the software of the actual background screen. In addition, since this equipment is accessible only to designated educational institutions, new trainees have no choice but to be limited in improving their proficiency in countermeasures under various unusual situations. In addition, it is somewhat unsuitable for ordinary people who want to experience train driving in terms of practicality/popularity.

Therefore, in order to overcome the limitations of the existing training simulator, it is important to develop a scale model for a general-purpose railway vehicle cab.

Each device of the railroad vehicle simulation simulator uses the same product as the actual vehicle in appearance and various devices in consideration of the driving sense, but some are modified by computer control method or replaced with high-resolution video by computer graphics. The trainee's operating device handling information is expressed as track images, video effects, sound effects, warning/indicators, and alarms according to the simulation calculation results using the train operation algorithm in the control computer. In addition, in order to improve the trainee's proficiency in stopping in the right position when entering the train platform, long driving practice time using the propulsion/braking control panel that directly affects the driving sensation is required.

Studies on the domestic railway vehicle simulation training machine have been mainly conducted from the software point of view using the previously manufactured railway vehicle simulator. As an example, determination of train speed profile for minimum energy consumption, analysis of safe driving effect of safety devices at railroad crossings, development of ATP train spacing control simulator for wireless communication-based train control system, and research on propulsion control simulator for maintenance and training of rolling stock was performed. Recently, Seo Eun-young and others studied the alternative training effect of VR simulator for railroad education as a complementary device to the train driving simulator currently in operation. However, the above studies are limited to maintenance and improvement of education and training functions from a software point of view, and efforts to miniaturize while being inexpensive in terms of software/hardware are still insignificant.

The present invention is to solve the above problems, and to provide an inexpensive and miniaturized electric train personal simulator.

In addition, it is intended to provide a miniaturized train personal simulator capable of realizing the same or similar conditions as the actual driving of the train.

In addition, it is intended to implement various controllers and training software only with one computer (software server 10).
