Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Width-limited door designs, and often organizes width-limited door and is made up of one group of single arm support and two groups of suspension rods, and the structure of the setting of width-limited door subject and suspension rod as depicted in figs. 1 and 2.
In figure, 1 is the spacing distance between single armed suspension bracket, and it is 3 times of vehicle commanders, and 2 represent the suspension rod that single armed suspension bracket is installed, and 3 represent single armed suspension bracket, and 4 represent pressure sensitivity cable.(distance in Fig. 1 between two suspension rods is overall width+60CM, and a suspension rod one fixes on edge positions, and that is a suspension rod of speed limit width-limited door is pressed on line, is three times of vehicle commanders between two groups of suspension rods.)
As shown in Figure 2, suspension rod comprises spring 21, and (spring upper end is bolted on support Top Crossbeam, lower terminal sleeve, the lower end connecting-rod body 23 of sleeve pipe, place mercury sensor inside sleeve pipe, cable is connected to the mercury sensor inside sleeve pipe from spring inner.), mercury shock sensor 22, the body of rod 23, pull chain 24 be chain structure, adopt stainless material, such as stainless steel, also can use zinc-plated cast iron), cast iron attachment cap 25 and strong magnet 26.The material of the body of rod 23 is hollow aluminium-plastic pipe, has good remoldability.Damping after the effect of spring is to collide, and must reset after collision.Wire passes from spring center, is connected on the mercury shock sensor between spring and the body of rod.The placed angle of mercury shock sensor will determine the sensitivity of suspension rod signal, sensor connecting elements has carried out waterproof and angular adjustment design, the metal of body of rod lower end pulling chain can be coordinated when mounted to regulate together, and (pull between chain and the body of rod is that screw-socket connects, the tightness of reconciling screw-socket can reconcile the height and level of stretch that pull chain), until reach the examination request of actual examination hall environment.Empirically with best with level ground angle 45 ~ 60 degree of effects in examination vehicle travel direction (namely mercury shock sensor becomes 45-60 degree with surface level), this parameter does not consider that strong wind and other weather conditions cause to obtain Special Influence.The other end of the body of rod connects pulling chain, pull chain bottom and have a diameter 15mm, high 10mm cast iron cylinder (general employing diameter 12-15mm, high 10-15mm), ground naturally droops the strong magnet (diameter at 15-20mm, 1500 Gausses) that position embeds diameter 20mm with suspension rod, under non-collision environment, cast iron attachment cap is adsorbed by strong magnet, pulls chain and becomes tight state.
This designs feature is: what 1, speed limit width-limited door subject limited is lower velocity limit, in the driving path of all places this section's object speed of a motor vehicle and hundred meters add downshift subject all belong to speed higher subject, high in the collision frequency of examination king-rod body, and compare reversing warehouse-in, section's object impact amounts such as vehicle positioning stop are large, if do not adopt spring and pull chain mode, just simple suspension rod mode page easily causes the distortion of the body of rod even to damage.2, by regulating spring connecting screw and the pulling dynamics pulling the chain length adjustment body of rod, in order to avoid judge by accident because wind-force or other weather conditions cause to obtain.3, mercury shock sensor sensitivity can by its place angle of inclination and and Vehicular impact direction angle regulate.This angle must affect by factors such as examination vehicle size, weather conditions, needs Field adjustment under the environment of examination hall.
Two, the design of route running is in violation of rules and regulations prevented
This test subject requires vehicle when passing through this subject successively by three speed limit width-limited doors, if not route running according to the rules, this Course Examination is considered as defective, in order to prevent vehicle from driving through from width-limited door after entering subject, the position that this subject is in alignment with width-limited door arranges pressure sensitivity cable sensor device (in Fig. 1,4 dotted lines represent the position that pressure sensitivity cable is arranged).Pressure sensitivity cable sensor device is made up of pressure sensitivity cable and pressure sensitivity cable signal amplifier.Pressure sensitivity cable produces small electric current after being squeezed, through pressure sensitivity cable signal amplifier, (amplifier is arranged on pressure sensitivity cable one end near road side, be Specifically connect pressure sensitivity cable road outside one end) it is amplified, signal after amplification is 12 volts of pulse signals, and this signal can be used as switching signal through process and processes.In examination process, if vehicle not route running according to the rules, then can roll pressure sensitivity cable, produce on-off model high level, then total marks of the examination are defective thereupon.
Four, the setting of subject reference position: enter when this subject takes an exam at vehicle and need start signal setting.Start signal adopts middle distance active RFID to develop.The active card of RFID selects coverage to be 5 ~ 8 meters of specifications, arranges active card, arrange RFID card reader at roof location in subject starting point and vehicle roof with high position, and card reader is that RS232 data-interface exports, and Card Reader is spaced apart 10 seconds.Enter in reading range when vehicle travels, card reader reads the rfid card sheet data corresponding to speed limit width-limited door subject, carry out resolving this Course Examination of rear mark to start, shown by vehicle-mounted computer simultaneously and coordinate voice message examinee speed limit width-restricting door examination subject to start.
Five, the judgement that terminates of speed limit width-restricting door examination
The judgement that examination terminates is divided into two classes, the first kind is that underproof examination terminates, namely when examinee occur lance and not according to the rules route (enter from the position in Fig. 1 lower right corner 2, successively by three speed limit width-limited doors) to exercise etc. and cause examination is defective, this kind of defective judgement judges in conjunction with the on-off model of suspension rod and the on-off model of pressure sensitivity cable.Equations of The Second Kind is qualification determination, and namely examination vehicle is after entering subject, and operating range has exceeded in subject exercises distance and produces there are no defective signal, then judge that examinee passes the examination.
Six, principle of work and step
Signal verification: needed the on-off model in checkout area earth signal, this place to be high level before examination starts effective, binary digit " 1 " is effective after converting digital signal to, low level is normality, if there was high level to import into before examination starts, represent that wrong signal occurs, must investigate, in order to avoid cause erroneous judgement.
Step one: examination vehicle enters speed limit width-limited door region, be arranged on the card reader of examination roof end reads the active RFID signal be arranged near subject starting point, carries out voice message: " speed limit width-restricting door examination starts " in examination car.RFID card reader is read the site error that active RFID card sends radiofrequency signal and is less than 1 meter.Driving vehicle enters section's object distance counting and resets.And from Card Reader point record operating range.
Step 2: examination vehicle travel route and be not less than 20 kilometers/hour of speed of a motor vehicle by this subject according to the rules, if operating range is (by note rice wheel record, a kind of device of recording distance of passive rotation, on transmission shaft below the car body being arranged on car, drive axis, note rice wheel also rotates, can the operating range of measuring vehicle and speed by the conversion of transmission shaft and wheel diameter) do not reach and roll this subject distance away from and have touching lever signal, then deduct corresponding scores, continuous touching lever examination defective (lance is just defective).Truck-mounted computer provides the voice message of grazing stake bar.
If examination vehicle operating range rolls this subject distance away from not reaching, and has pressure sensitivity cable signal to import into, then judge this subject defective (as long as there is any one pressure sensitivity cable signal, just defective).Truck-mounted computer provides and travels voice message not according to fixed course.
Step 3: speed lower than 20 kilometers/hour (operating range of note rice wheel is exactly travel speed divided by running time) according to reduction of speed deduction corresponding scores, by the corresponding exam score of also deduction of having moveed backward (once completing 10 points, button by reversing) in subject.
If in test subject, examination student is in violation of rules and regulations by examination of having moveed backward, deduction corresponding scores.When there being backing car gear sensor signal to import into, then do corresponding judge process.
Step 4: examination vehicle operating range exceedes and rolls this subject distance away from, then judge that this subject is qualified, uses truck-mounted computer to play voice " speed limit width-limited door Course Examination terminates, this subject qualified ".
