Description
Technical field
The present invention relates to a kind of road speed-limiting device for vehicles, especially relate to a kind of barrier-free automatic lifting speed bump and control method.
Background technology
At present, the deceleration strip that is arranged on road is all strip, point-like or the block structure that directly is fixed on the road surface, and purpose is to force reducing speed of motor vehicle, with the life security that guarantees by way of the road junction, the road section traffic volume participant is easily sent out in school, dwelling house and traffic accident.Although the generation that deceleration strip can reduce traffic accident to a great extent is set, yet also has problems, as: the swell fixture that deceleration strip is left on the way after damaging probably punctures doughnut, thereby causes to lose control of one's vehicle; The noise that vehicle jolts has seriously disturbed the life of surrounding resident; Existing deceleration strip can't be distinguished motor vehicle and bicycle, causes very easily when ice and snow weather that therefore bicycle breaks away; Existing deceleration strip causes that the vibrations of car body are larger to goods in car and personnel's comfort degree; Existing deceleration strip can't embody the principle of " prize is penalized fast slowly ", even that is to say low vehicle speeds, still can clash into deceleration strip, therefore tire and car body is had injury.
for the problems referred to above, relevant scholar has carried out research to a certain degree, Chinese patent application the 200720021665.6th, 200720174551.5, 201120018191.6, 201120103041.5 and disclose respectively design scheme and the implementation method of various new deceleration strip in No. 201010261228.8, yet, there are the following problems for existing technology path: the load abirritation that utilizes hydraulic pressure, though can reduce deceleration strip to the impact of car body and tire, but need the speed of a motor vehicle very low, for example in the highway section of speed limit 50km/h, if the speed with 50km/h is travelled, still can experience obvious impact force by deceleration strip, if the low velocity with 10km/h is travelled, although impacting sense reduces, will cause local traffic stream to block up in peak period on and off duty, make troubles to traffic participant, although utilize swash plate to coordinate spring design to reduce the cost of deceleration strip, better mechanical property can only be applicable to one way road, if highway needs interim maintenance, make one-way street into two-way street, can cause the obstacle that travels of the vehicle that drives in the wrong direction, so range of application is restricted.In addition, in the existing 80 remainders patent application document relevant to deceleration strip, all do not embody the fairness of " prize is penalized fast slowly ".So-called " prize is penalized fast slowly ", that the vehicle that travels by the speed limit requirement is rewarded and the vehicle of driving over the speed limit is punished, this is also the purpose that deceleration strip is set: prize can guarantee circulation of traffic slowly, penalize when can guarantee soon the over-speed vehicles forced deceleration vehicle of driving against traffic regulations is caused certain damage, thereby it is fair to embody traffic.
Therefore, study a kind of novel deceleration strip,,, will greatly improve the comfort level of road running and guarantee traffic safety the over-speed vehicles forced deceleration without any damage the vehicle that travels by the speed limit requirement, transfer the enthusiasm that the driver observes traffic rules and regulations, simultaneously, can improve non-automotive vehicle safety, reduce the surrounding resident ambient noise, extend tyre life, reduce the car inspection and repair expense.

As shown in Figure 7, the control method of barrier-free automatic lifting speed bump provided by the invention comprises the following step that carries out in order:
1) the S1 stage of system's power-on self-test: in this stage, system switches on and checks and then enters the S2 stage by related hardware equipment;
2) the S2 stage that whether equipment is normally judged; In this stage, master controller 20 will judge that related hardware equipment is improper, if be judged as "Yes", enter the S4 stage; Otherwise, forward S3 stage of abnormality processing to;
3) the S3 stage of abnormality processing: in this stage, the user manual is getting rid of that hardware device is abnormal, is again switching on and enter the S2 stage after fault;
4) radar meter gathers the speed of a motor vehicle and is transferred to S4 stage of master controller: in this stage, radar meter 1 will be measured the travel speed of car and feed back to master controller 20, then enter the S5 stage;
5) judge the S5 stage whether vehicle exceeds the speed limit; In this stage, master controller 20 will judge that whether the speed of a motor vehicle that radar meter 1 is measured surpasses fixing speed, if judgment result is that "Yes", enters the S6 stage, otherwise returns to the S4 stage;
6) the S6 stage of deceleration strip rise; In this stage, master controller 20 will rise brake flap 3 by relevant push mechanism and support component, then enter the S7 stage;
7) judge whether to also have the S7 stage of new over-speed vehicles; In this stage, master controller 20 will judge that whether radar meter 1 detects new over-speed vehicles, if judgment result is that "Yes", returns to the S6 stage, otherwise enters the S8 stage;
