Design of air-conditioning system for urban railway simulation training device

With the rapid development of urban rail transit, the demand for related training equipment in rail transit industry has increased sharply. This paper studies the function and basic working principle of the subway vehicle air conditioning system and proposes an overall design scheme for the subway simulation training device of the air conditioning system. The simulation design reduces the voltage, simplifies the circuit, and adopts modular design. It also realizes the PLC control of the lower computer and the human-machine interface display of the upper computer. The practical training device can train personnel efficiently and professionally, filling the gap of training equipment for the urban rail transit air conditioning system.
