A pedestrian detection device for blind spots on buses with risk avoidance function includes a powered telescopic frame, a pedestrian recognition module, an audible and visual alarm, an environmental recognition module, a geographic location recognition module, an emergency avoidance module, and an embedded microcontroller. The powered telescopic frame is installed on the front roof of the bus. The pedestrian recognition module, environmental recognition module, and emergency avoidance module are all mounted on the powered telescopic frame. The audible and visual alarm and the embedded microcontroller are both installed on the interior ceiling of the bus, directly below the powered telescopic frame. The geographic location recognition module is mounted on the embedded microcontroller. The embedded microcontroller is connected to the powered telescopic frame, pedestrian recognition module, audible and visual alarm, environmental recognition module, geographic location recognition module, and emergency avoidance module via signals. This invention can effectively identify pedestrians in the blind spots of buses, alert the driver to driving safety through the audible and visual alarm to avoid traffic accidents, and also has risk avoidance and emergency avoidance functions.

The invention belongs to the technical field of infrared illuminants, and particularly discloses a liquid phase forming ceramic-modified filler composite infrared illuminant and a preparation method thereof.The structure of the liquid phase forming ceramic-modified filler composite infrared illuminant sequentially comprises a substrate, a transition layer and a functional layer from bottom to top; the transition layer is prepared by doping a high-temperature insulating material with precursor polymer ceramic through high-temperature pyrolysis and curing, and the functional layer is prepared by mixing the precursor polymer ceramic with modified filler through high-temperature pyrolysis and curing. The liquid-phase forming ceramic has excellent high-temperature performance, has a flexible processing technology and can be compatible with an MEMS technology, and the performance of the material can be regulated and controlled by modifying filler doping, so that the high-temperature stability of the infrared luminophor is improved, the design period is shortened, the preparation cost is reduced, and the spectral efficiency of the luminophor is improved.
