Reverse anti-collision alarm device

The invention relates to a reverse anti-collision alarm device, belonging to the field of automatic control technology; a singlechip (4) of the reverse anti-collision alarm device is respectively connected with an LED display device (1), an alarm device (2) and a transmission circuit (5); a voltage-stabilized power supply (3) and a receiving circuit (7) are connected with the singlechip (4); the voltage-stabilized power supply (3) is connected with the alarm device (2) which is connected with the LED display device (1); the transmission circuit (5) is connected with a transmitting probe (6); and a receiving probe (8) is connected with the receiving circuit (7). The reverse anti-collision alarm device is controlled by the singlechip, is compact in structure, small in volume, lower in cost and rapid in response speed, and is capable of responding in time and reminding a driver of taking action for avoiding the situations such as collision and the like, thus reducing the incidence rate of accidents.
