This disclosure presents a method and system for outputting vehicle infotainment system information. The specific implementation of the method includes: On the vehicle infotainment system: preprocessing the vehicle infotainment system information to be output to obtain watermark data; performing frequency domain transformation on display image data to be written to the frame buffer to obtain frequency domain data; embedding the watermark data into the frequency domain data to obtain embedded data; converting the embedded data into time domain data; and writing the time domain data into the frame buffer for image display. On the server: responding to receiving an image of the vehicle infotainment system display screen from the vehicle infotainment system or a mobile terminal, performing frequency domain transformation on the image to obtain embedded data; extracting watermark data from the embedded data; and parsing the vehicle infotainment system information from the watermark data according to a predetermined format. This implementation is simple to operate, can quickly determine vehicle infotainment system faults, and improves efficiency and flexibility.

This invention discloses an isolation and protection system for rotating machinery. The isolation and protection system includes a pneumatic module and an isolation module. The pneumatic module includes a pilot valve, an air inlet pipe, and a rotating air chamber. The pilot valve is fixed, and the rotating air chamber rotates around its own axis. The air inlet pipe is connected to the rotating air chamber through a bearing. The isolation module is equipped with a rotary joint, which includes a stationary channel, an adapter, and a rotating channel that are interconnected. One end of the stationary channel is fixedly connected to the pilot valve, and the other end is fixedly connected to the adapter. One end of the rotating channel is fixedly connected to the air inlet pipe, and the other end is connected to the adapter. The rotating channel is rotatable relative to the adapter around its axis. By setting a rotary joint, this invention physically isolates the torque of the air inlet pipe and the pilot valve, preventing abnormal rotation of the air inlet pipe from being transmitted to the pilot valve and causing the housing to rupture when the bearing is damaged, thus avoiding serious economic losses and production interruptions.
