Design and implementation of automatic anti-collision alarm system for automobiles

Technology is advancing, humanity is making progress, and the number of intelligent devices is gradually increasing. Smart devices are also becoming increasingly popular in some specific occasions or repetitive working environments. If a vehicle does not prevent automatic rear-end collisions, it will fail to give early warnings before the collision occurs, thus failing to serve as a safety warning. The automatic anti-rear-end collision alarm device system designed this time adopts a single-chip microcomputer as the controller. This function is achieved by designing the hardware of the device and creating a program for the device software. The STC89C51 single-chip microcomputer serves as the controller responsible for the overall operation of the equipment and improves the entire device through peripheral auxiliary circuits. The LCD1602 serves as the display interface to achieve human-machine interaction. Parameter input is realized through buttons. The ultrasonic sensor is used to detect vehicle distance. The alarm circuit is designed with a buzzer. Reminders are provided through the buzzer's sound. Voice reminders are achieved through the voice broadcast module. The design of an automatic anti-rear-end alarm device is realized by completing the target function of the task through a single-chip microcomputer and peripheral assistance. The advantage of this design lies in the fact that the anti-collision intelligent vehicle will also have a profound impact on today's vehicle design, development, specific manufacturing processes, manufacturing costs and even production tools, which also provides a strong guarantee for the safety of human life and property.
