The utility model automobile intelligent speed restrictor is to install with various automobiles, mounting structure-guiding that design has general character is subjected to force mechanisms, the advantage of this mechanism is the position of installing to be narrowed down to have only between stress point and the acting point, occupies thereby reach hardly; Another advantage of this mechanism is the combination that is subjected to force mechanisms by be flexible coupling axle and guiding, has realized the transfer of the direction of power easily, thereby the selection of speed limiting device installation site is increased greatly, applicable all automobiles.The direct current high-speed electric expreess locomotive that the speed limiting device is selected for use, suitable voltage are 12V, 24V; Change speed gear box is designed to 9: 1 column type inner gear division center of speed ratio; In 3 seconds of whole course of action, the speed limit error can satisfy various speed limit requirements less than 3%.Be located at two limit switches that are provided with the interval of cooresponding casing one side of screw rod the travel position of nut is carried out accurate positioning control, play position-limiting action.The speed limit of velocity of electrons controller, can one grade of setting, also can many grades of settings, or letter of acceptance road speeds wireless signal switches or the electronic chart signal switches and sets, the shift knob of many grades of speed selection is manually selected for chaufeur on the controller panel.
The utility model automobile intelligent speed restrictor principle of work, the tachogen of installing before the car speed mileage meter reaches controller with tach signal, monolithic processor in the velocity of electrons controller is handled according to velocity amplitude or the switching value set in advance: automobile driving speed moves in restricted portion, then controller toggle speed killer not; When automobile driving speed reaches setting value or switching value, when the micro computer of controller is controlled the pulling force relay immediately and is sent " tension " signal, high-speed electric expreess locomotive is rotated in the forward, cooperation by change speed gear box and screw rod, produce powerful pulling force, nut produces displacement under the effect that screw flight rotates, strain the axle that is flexible coupling; Throttle is pulled on, travelled by setting speed; This speed restrictor forces to promote 4 to 5 centimetres by the axle that is flexible coupling to the pedal board of automobile exactly under the control of limit switch, 10～15 centimetres in large-tonnage automobile, thus throttle position is limited and can't steps on; The velocity of electrons controller sends chimes of doom simultaneously, and expression current driving speed has exceeded limits value, makes car deceleration; When car speed during less than setting value, the velocity of electrons controller is control relay again, when sending " loosening " signal, the axle that is flexible coupling is loosened in the contrarotation of speed limiting device, speed restrictor oppositely loosens the axle that is flexible coupling exactly to the home position under the control of limit switch, gas restores to the original state again, closes annunciator simultaneously, and automobile can travel as usual again.
The use of the utility model automobile intelligent speed restrictor divides automatic guidance and manual mode:
1, variable electronic speed road sign signal automatic switching mode
Traffic road administration department need set up the location of speed road sign to set up new road speeds road sign at each, and this road sign shows with the high brightness charactron, can change speed road sign value as required at any time; Simultaneously by being installed in the sender unit transmission speed switching signal ceaselessly on the road sign; Like this, the vehicle in travelling receives wireless restricting signal and visual restricting signal simultaneously; Wireless restricting signal switches everywhere to the speed control value of automobile intelligent speed restrictor; After the switching, automobile will travel in new specified speed scope; Optical signal has carried out speed limit reminding as the continuity of operating habit to chaufeur.
Network if set up road travel speed guidepost system, road administration commander department just can regulate and control the whole traffic network speed of driving in commander's operator's compartment, and all automobiles travel same speed command by appointment.
2, GPRS electronic chart speed signal automaticallyes switch
The utility model is connected with the GPRS automatic navigation system, and the place that will demarcate according to electronic chart, speed is the switching controls value exactly, the different highway sections different speed of will travelling.
3, manually control predefined speed button is arranged on the controller, chaufeur can be selected immediately according to road sign.
After on the various automobiles the utility model being installed, company or safety traffic department just can carry out the management of actv. road speed to vehicle in use.Company or safety traffic department can force to limit to car speed with the method that sets in advance, and automobile can only travel in the speed range of regulation, thus the probability of reduction accident greatly.Just can realize the hypervelocity restriction and the overspeed alarming of automobile very easily.If the road speeds sign is used controlled variable electronic display speed marker instead and is added the radio speed sender unit, the utility model can be accepted this signal instruction in the process of moving, switch speed limits value everywhere, automobile is carried out effective velocity control, except omnidistance Control of Automobile speed, and can carry out speed control respectively to the period of daytime, night or other specific (special) requirements.
The utility model cooperates with the GPRS satellite navigator, then can be according to the speed of electronic chart indication to the flexible Control of Automobile speed in each highway section, make the automobile different speed of travelling in different highway sections.
In sum, the utility model automobile intelligent speed restrictor structure design compactness, each several part is stressed, and evenly application of force intensity is big, and control is accurately, and is safe and reliable.
