Problems solved by technology

The disadvantage of static deceleration belt design is that it cannot adapt to changes in the speed environment in time. Even when the vehicle is driving at a speed lower than the speed limit, it will still be disturbed by deceleration.

Abstract

The invention provides a humanized adaptive speed reducing system and a design method thereof. The humanized adaptive speed reducing system judges whether to forcibly reduce the speed of an arrival vehicle or not by detecting the speed of the vehicle and comparing the speed with a road section speed limit value, and consists of a speed reducing device, a transmission device, an electric motor, a transmission cable, a singlechip and a vehicle detection coil, wherein the speed reducing device is connected with the transmission device; the transmission device is connected with the electric motor; the electric motor is connected with the singlechip through the transmission cable; and the singlechip is connected with the vehicle detection coil. The design method of the humanized adaptive speed reducing system comprises the following steps of: setting a section speed limit sign, arranging the speed reducing device, pre-checking the speed of a running vehicle, comparing the speed with the section speed limit value, transmitting a command, judging whether to reduce the speed and recover a speed reducing initial state or not, and the like. Only the running speed of the vehicle is needed to be measured and compared with a speed limit threshold value, so that whether the command is transmitted to the speed reducing device or not is judged, and the system is convenient to operate, has small construction investment, and can create good economic benefit.

Description

(1) Technical field [0001] The invention relates to traffic science, specifically a design method of a humanized self-adaptive deceleration system. (2) Background technology [0002] Speed ​​bumps, also known as speed bumps, are road safety facilities used to slow down the speed of motor vehicles and non-motor vehicles, and play an important role in suppressing the occurrence of traffic accidents. Speed ​​bumps usually work together with certain speed limit signs, which can not only ensure the safety of the car during driving, but also serve the purpose of buffering and decelerating to reduce traffic accidents. [0003] In recent years, with the development of our country's society and economy, the road grade has been continuously improved, the number of cars has increased rapidly, and traffic accidents on the road have become increasingly prominent. According to statistics in recent years, death caused by speeding accounts for about 15% of the total number of road traffic ...
