Abstract

The invention provides an intelligent control device for automatically detecting a vehicle speed and a vehicle spacing and relates to a control device capable of automatically detecting the vehicle speed and the vehicle spacing and automatically alarming if the vehicle speed or the vehicle spacing exceeds limits. The intelligent control device is provided with a speed detecting sensor CS, a spacing detecting sensor CJ and a detection and voice alarm circuit, wherein the speed detecting sensor CS is mounted on an automobile speed meter circuit; the spacing detecting sensor CJ is mounted on the front part of an automobile; the detection and voice alarm circuit is mounted on an electronic circuit board of an automobile control panel; and the detection and voice alarm circuit comprises a volt current condenser (VCC), adjustable resistors RT1-RT3, a OR gate OR, resistors R4-R6, capacitors C1-C3, a 555 timer chip, a relay K and a SPEAKER. Under the condition of mounting the speed detecting sensor and the spacing detecting sensor on the automobile, the detection and voice alarm circuit is used for detecting whether the automobile is at a safety speed and at a safety spacing and alarming if the speed and the spacing exceed safety ranges.

Description

technical field [0001] The invention relates to an intelligent control device for automatically detecting vehicle speed and vehicle distance, relating to a control device which can automatically detect vehicle speed and vehicle distance, and can automatically alarm when the vehicle speed exceeds the limit or the vehicle distance exceeds the limit. Background technique [0002] According to statistics in recent years, excessive vehicle speed and inappropriate vehicle distance are one of the main factors that induce traffic accidents. Maintaining safe driving speed and vehicle distance has become one of the key contents to ensure the safety of life and property of the majority of traffic participants. . [0003] Speeding will affect the driver's observation and judgment accuracy. The study found that the higher the speed, the farther the driver's viewpoint and the narrower the field of vision. According to the experiment, if a person's vision is 1.2 when standing still, when...
