The intelligent protection safety device comprises a singlechip microcomputer, a millimeter microwave radar speed and distance measurement sensor, a Hall integrated device speed measurement sensor, a magnetically controlled reactor, an acousto-optical alarm device, a brake control device and an instrument panel, wherein the millimeter microwave radar speed and distance measurement sensor and the Hall integrated device speed measurement sensor are connected to the input end of the singlechip microcomputer, the magnetically controlled reactor, the acousto-optical alarm device, the brake control device and the instrument panel are connected to the output end of the singlechip microcomputer, and a singlechip microcomputer AT89C2051 is used as the singlechip microcomputer. Accurate self-control is realized on an automobile by the method adopting double measurement including speed measurement and distance measurement. The On/Off state of the automobile collision avoidance device can be manually controlled and displayed on the instrument panel. The acousto-optical alarm device of the automobile not only can remind the self automobile driver, but also can remind a rear automobile to keep a safe running distance. The intelligent protection safety device is highly intelligent, processes commands at a speed which is far higher than the highest reaction speed of the brain and is suitable for being arranged on all types of automobiles to reduce accidents.
Description
Technical field
The present invention relates to a kind of anti-collision device for automobile field, particularly a kind of dangerous intelligent protection safety device of the auto against casualties that reduces.
Background technology
Automobile collision accident be mostly too fast by road speed, vehiclar gap is too small, the brake wait not in time factor to cause.According to latest survey, show: the collision case rate of traffic accident is all increasing progressively every year, and 75% collision case occurs in the low vehicle speeds process, wherein has the accident chaufeur before collision occurs of half not touch on the brake at all.Existing anti-collision technique only is confined to the mode that single tests the speed, finds range or test the speed and finds range and combine, although can greatly reduce the rear-end collision accident occurs, play the effect of escorting, but produce sometimes error, bring unnecessary trouble to the driver, and this class device price is higher, can't popularization and application.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the test the speed dual method of measurement of range finding have self-actuating brake, the automatic dangerous intelligent protection safety device of the multi-functional minimizing auto against casualties of reduction of speed of a kind of employing is provided.
The present invention solves its technical matters and takes following technical scheme to realize:
A kind of dangerous intelligent protection safety device of the auto against casualties that reduces, the millimeter microwave radar velocity measurement distance measuring sensor that comprise micro controller system, with the micro controller system input end, is connected and Hall integrated device tachogenerator, the magnetic reactance device, acoustic-optic alarm, braking control device and the gauge panel that with the micro controller system mouth, are connected, described micro controller system adopts the AT89C2051 micro controller system.
And described gauge panel consists of telltale and shift knob.
And described Hall integrated device tachogenerator consists of hell integrated sensor and the rotating disk that permanent magnet is housed, wherein, hell integrated sensor adopts the A3144E chip of the integrated magnetosensitive circuit of semiconductor technology.
Advantage of the present invention and good effect are:
1, the present invention adopts the method for the dual measurement of range finding of testing the speed, and realizes the accurate automatic control of automobile; The on off state of anti-collision device for automobile can manually be controlled, and is presented on gauge panel; The acoustic-optic alarm of automobile not only can be pointed out this car chaufeur, also can point out rear car to keep safe running distance; The present invention is highly intelligent, and the speed of processing instruction higher than the fastest response speed of human brain, is suitable for being arranged on the installation of various types of automobiles far away, the generation of minimizing accident.
The accompanying drawing explanation
Fig. 1 is that structure of the present invention connects block diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described:
A kind of dangerous intelligent protection safety device of the auto against casualties that reduces, a kind of dangerous intelligent protection safety device of the auto against casualties that reduces, the millimeter microwave radar velocity measurement distance measuring sensor that comprise micro controller system, with the micro controller system input end, is connected and Hall integrated device tachogenerator, the magnetic reactance device, acoustic-optic alarm, braking control device and the gauge panel that with the micro controller system mouth, are connected, described micro controller system adopts the AT89C2051 micro controller system.Described gauge panel consists of telltale and shift knob; Described Hall integrated device tachogenerator consists of hell integrated sensor and the rotating disk that permanent magnet is housed, and wherein, hell integrated sensor adopts the A3144E chip of the integrated magnetosensitive circuit of semiconductor technology.
In conjunction with Fig. 1, set forth principle of work of the present invention: the feedway of millimeter microwave radar velocity measurement distance measuring sensor and receiving device are for the sending and receiving millimeter microwave, detect relative distance and the speed of front truck and this car, Hall integrated device tachogenerator detects this car self speed of a motor vehicle, utilize the accurate detection speed value of millimeter microwave radar velocity measurement distance measuring sensor and Hall integrated device tachogenerator and distance value, and feed back to rapidly micro controller system, micro controller system is through computing, relatively, then judge, control automatic reduction of speed and the brake of automobile, and data are presented on the telltale of gauge panel.When distance and speed are safety value, acoustic-optic alarm will not produce effect; When distance and speed are the warning value, start acoustic-optic alarm, adopt voice suggestion and green alerting driver to be braked; When distance and speed are dangerous values, start acoustic-optic alarm, adopt audio alert and red light alerting drivers, and this car is carried out to self-actuating brake; When distance and speed are between warning value and dangerous values the time, start acoustic-optic alarm, adopt voice suggestion and yellow light alerting drivers, and this car is carried out to self-actuating brake.In the development process of native system, according to different driving situations, more deep discussion warning value and the situation of dangerous values, warning value model and dangerous values model have been set up, then, the basic function that will reach according to chaufeur, the system schema of design warning value, safety value, dangerous values.
It is emphasized that; embodiment of the present invention is illustrative; rather than determinate; therefore the present invention is not limited to the embodiment described in the specific embodiment; every other embodiments that drawn by those skilled in the art's technical scheme according to the present invention, belong to the scope of protection of the invention equally.
