Abstract

The invention discloses a device for preventing rear-end collision on highways. The device comprises a circuit board. A speed measuring circuit (1), a position measuring circuit (2), a computer system (3) with a single chip microcomputer, a buzzer (4) and a wireless transmitting and receiving circuit (5a) are mounted on the circuit board, an output end of the speed measuring circuit (1) and an output end of the position measuring circuit (2) are connected with input ends of the computer system (3) with the single chip microcomputer, an input end of the buzzer (4) is connected with an output end of the computer system (3) with the single chip microcomputer, and a port of the wireless transmitting and receiving circuit (5a) is connected with a port of the computer system (3) with the single chip microcomputer. Devices can be used with one another via wireless signal connection. The device has the advantages that a warning effect can be realized when a vehicle which runs at a slow speed in front of a vehicle with the device is separated from the vehicle with the device by a certain distance, and the device with the wireless transmitting and receiving circuit is low in cost; the device can be mounted on a charge card on a highway, is convenient to use and can be applied on a large scale; the device is powered by batteries and can be reused for a long time.

Description

technical field [0001] The invention relates to a reminder device for preventing rear-end collision accidents of automobiles on expressways. Background technique [0002] At present, the anti-rear collision device adopted by automobile mainly includes speed measuring device, distance measuring device, computer processing device and alarm device. The terminal is connected with the signal input terminal of the early warning device. The speed measuring device and the distance measuring device transmit the speed and distance information to the computer processing device, and the computer processing device judges whether the speed and distance information meet the preset safety standards, and outputs an alarm signal to the alarm device when the standard is not met, and the alarm device receives To this signal an alarm is issued. Although this kind of device can realize the alarm, the speed measuring device and the distance measuring device basically use ultrasonic radar or infr...
