The invention discloses an anti-collision
alarm device for a vehicle, which comprises a shell provided with a control panel and a central processor arranged in the shell. The central processor is respectively connected with a GPRS module, a GPS module, a data storage
chip, and also connected with a range
radar, a camera, an anti-collision sensor, a vehicle speed sensor and a
sound box. The control panel is provided with buttons for selecting road conditions, driver age group and vehicle model, and also can be provided with a display screen. The
sound box is externally connected with an independent
sound box or connected with a self
acoustics system in the vehicle. The anti-collision
alarm device has the advantages that the anti-collision
alarm device combines each parameter of a factor affecting running safety distance to carry out analysis by synthesis according to distance data of a front object measured by the onboard
radar, obtains more scientific and accurate running safety distance, mildly and effectively reminds a driver to notice through two-level prompt
modes of distance early warning and distance warning, can well prevent the vehicles from colliding, and ensures running safety.
