Abstract
The utility model relates to a contact type device for detecting vehicles operated by using wheels and vehicle weight. The detecting device is composed of a base, a cover plate, a buffering cushion, static contacts, and movable contacts, wherein, the static contacts and the movable contacts are connected to ground, the cover plate is in a Y shape and is covered on the triangular base, the buffering cushion is arranged between the cover plate and the base, the static contacts are fixed on the base, and the movable contacts are attached on the cover plate. The detecting device is placed on the ground without excavating a road surface. Used equipment is cheap, and the service life is long, and thus the utility model has the advantages of low cost, and reliable operation.
Description
The utility model relates to a kind of contact wagon detector that relies on wheel pressure and dead weight folding, belongs to the traffic management technology field.
Occasions such as road traffic supervision, highway toll and parking lot management all to use can judge whether vehicle this by or " wagon detector " parked.Common having at present:
1, ring coil type: about 5cm place under the road surface, embedding large-scale (general about 2 meters * 2 meters) toroid winding.When vehicle, the steel vehicle frame changes coil inductance, measures its variable quantity with electronic circuit, can judge whether that car is at this.Shortcoming: (1) coil is fragile, especially in highway section that traction engine frequently passes through.(2) install and need excavate the road surface during maintenance coil, suspend traffic.
2, geomagnetic type: an embedding coil on the road surface with high permeability iron core, when having vehicle to cross, the steel vehicle frame changes the magnetic line of force that passes iron core, thereby produces induced potential, and indication has car to cross.Shortcoming: (1) can only detect the vehicle that crosses fast, can not detect whether vehicle parking is arranged.(2) need excavate the road surface during installation and maintenance, suspend traffic.
3, photo-electric: lay the luminotron that (or a several) luminous strong motherwort is subjected to modulation (frequency is generally tens of kilo hertzs) on the suitable height of a side in track, it is right that the two forms photoelectric sensor.Whether interdicted to judge whether vehicle is arranged according to modulated light at this by vehicle.Shortcoming: (1) must install photoelectric sensor in each both sides, track, causes driving restricted.(2) life-span is not grown (1~2 year).
The purpose of this utility model provides a kind of contact wagon detector that relies on wheel pressure and dead weight folding, makes detection means reliability height, long, easily use of life-span, and needn't excavated pavement.
The dependence wheel pressure of the utility model design and the contact wagon detector of dead weight folding are made up of the stationary contact and the moving contact of base, cover plate, cushion pad, ground connection.Cover plate becomes herringbone, covers on leg-of-mutton base, and cushion pad places between cover plate and the base, and stationary contact is fixed on the base, and moving contact is attached on the cover plate.
This detector response is rapid, as long as wheel crosses the b point, cover plate is with very fast upset, and contacts status changes immediately, causes the potential change of output signal O.This detecting device is placed on the ground, needn't excavated pavement.Used equipment all is inexpensive, long-life, so this detecting device cost is very low, and working depth is reliable.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A section partial enlarged drawing of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is the testing circuit figure of detecting device.
Fig. 5 is the user mode figure of detecting device.

Fig. 7 is the example that the utility model detecting device is used for parking lot management.
Fig. 8 is the example that this detecting device is used for traffic administration.
Below in conjunction with accompanying drawing, introduce content of the present utility model in detail.Among Fig. 1~Fig. 8, the 1st, base, the 2nd, herringbone cover plate, the 3rd, elastic buffering pad, the 4th, ground connection stationary contact, the 5th, moving contact, the 6th, vehicle, the 7th, parking stall, the 8th, detecting device, the 9th, car line ball signal, the 10th, the signal that makes a dash across the red light, the 11st, the bright signal of red light.
As shown in Figure 1, the dependence wheel pressure of the utility model design and the contact wagon detector of dead weight folding are made up of the stationary contact 4 and the moving contact 5 of base 1, cover plate 2, cushion pad 3, ground connection.2 one-tenth herringbones of cover plate are covered on leg-of-mutton base 1, and cushion pad 3 places between cover plate 2 and the base 1, and stationary contact 4 is fixed on the base 1, and moving contact is attached on the cover plate.
(ground) places device as shown in Figure 1 on the road surface, and it is by steel (or cast iron) base 1 and cover plate 2, resilient material (as rubber) cushion pad 3, the stationary contact 4 of ground connection, and moving contact 5 (compress with spring leaf, be placed on the cover plate side, and make contact and cover plate insulation) is formed.Its vertical view is seen Fig. 3.
Moving contact connects power supply U through resistance R 1, and connects lead-out terminal O (see figure 4) through resistance R 2.
During no vehicle (and vehicle is arranged but pressure wheel on 2 ab face the time), device is in the state of Fig. 1, the closing of contact, O point output low level.
Arrive as car, and wheel is when being pressed onto on 2 the bc face, device forwards the state of Fig. 5 to, and the contact disconnects, 0 output high level, and pointing out has car at this at this moment, sees Fig. 6.
After car sails out of, install the state of getting back to Fig. 1 because of action of gravity, get ready for detecting next group wheel.
Possible application and effect are given an example:
1, be used for parking lot management:
As shown in Figure 7, be sidelong on one of each end border, parking stall and put a detecting device 8 that width is enough.When car sails on certain parking stall 7 and the pressure wheel behind the detecting device, contact disconnects, and in the time of can beginning meter, and by contact control signal lamp, tell driver's car in order, and it is occupied to indicate the parking stall on whole Entrance display screen.(annotating: should require the driver to stop and put in place, guarantee the signal lamp action).
2, be used to monitor vehicles running red light:
As Fig. 8,, place this detecting device at intersection stop line place.After infrared brightness, if there is car to get over detecting device on the line pressure, can sends the signal 10 that makes a dash across the red light and notify the traffic police, and start the candid photograph video camera, the vehicle that makes a dash across the red light is filmed.
