This unit can automatically adjust the temperature and humidity control systems of the platform according to meteorological data such as temperature, humidity, wind speed, and precipitation. This dynamic adjustment ability ensures that the environment inside the platform always remains within a comfortable range under different weather conditions, improving the comfort and satisfaction of passengers. The air quality monitoring unit, on the other hand, real-time monitors the air quality inside the platform and is equipped with highly sensitive air quality sensors. These sensors can detect harmful substances, particulate matter, and gas concentrations in the air. The monitoring data is transmitted to the control system in real time for analyzing and processing the air quality status. According to the monitoring results, this unit controls air purifiers and ventilation systems, automatically adjusting their working states to effectively remove pollutants in the air and maintain air circulation. In this way, the air quality monitoring unit ensures the freshness and health of the platform environment, providing a clean and comfortable riding environment for passengers and also meeting environmental protection requirements.

[0054] Two-way communication unit: Supporting two-way data transmission from the bus to the platform and from the platform to the bus to ensure real-time information transfer.

[0055] Specifically, the encryption transmission unit uses the Advanced Encryption Standard (AES) algorithm to encrypt the transmitted data. The AES algorithm is a symmetric encryption algorithm that divides data blocks into fixed-size blocks and applies encryption transformations to each block to ensure that the data cannot be accessed or tampered with by unauthorized third parties during transmission. This encryption transmission unit not only protects the privacy and security of the data but also prevents security threats that the data may encounter during wireless transmission.
