1. The subway passenger guide screen has the characteristics of shockproof, dustproof, and explosion-proof.
2. Heat dissipation. The system adopts a highly enclosed environment for fanless cooling to ensure normal operation.
In terms of reliability, the system adopts a special plate making process, which has undergone special treatment on the vibration of circuit components and mechanical bending of circuit boards, enabling the system to have good resistance to rigid vibration and tension.
4. Adaptability of power supply. In response to the unstable power supply during locomotive startup and acceleration, the system adopts a very wide voltage tolerance range and good power protection. The system can work normally at very low pressures, reduce pressure at high pressures, and achieve safe operation of the system.
5. Differential signal transmission. In response to the complex electromagnetic environment and long-distance transmission of locomotives, the system performs differential processing on weak signals to ensure that audio and video signals are transmitted over long distances without attenuation, and adopts relay amplification to ensure signal quality after long-distance transmission.
