The utility model content
The purpose of the utility model is, the device that provides a kind of card sender to prevent to move backward many card takings, and whether it can detect the user has the reversing behavior, thereby can stop many card takings phenomenon of moveing backward.
The technical scheme of the utility model: a kind of card sender prevent to move backward device of many card takings; Comprise that the track that is located under the electric railing is provided with counting ground coil (Q3); Be located at the triggering ground coil (Q1) on the track of card sender cabinet side, also be provided with anti-reverse ground coil (Q2) after triggering ground coil (Q1).Anti-reverse ground coil links to each other with vehicle checker respectively with triggering ground coil, and vehicle checker is transferred to card sender with signal.
Above-mentioned card sender prevents to move backward in the device of many card takings, and said anti-reverse ground coil is located at and triggers 250mm place behind the ground coil.
Aforesaid card sender prevents to move backward in the device of many card takings, and said anti-reverse ground coil is the toroid winding that is embedded in the ground cutting groove of wide 6~8mm, dark 60~100mm with triggering the ground coil, and toroidal laterally wide 2.4 meters, vertical wide 1.2M.
The mounting process of ground coil: toroid winding is by multicore Low ESR annealed copper wire cable coiled, and the conduction total sectional area is about 1.5mm
2, outsourcing polypropylene or cross linkage tygon generally enclose electric wire in the groove of cutting as insulation course around four.Notch is drawn feeder line for 2 and is screwed in together with gel pitch or the sealing of epoxy resin material, and every meter twines more than 18 roads, and should take shielding measure.
Aforesaid card sender prevents to move backward in the device of many card takings, it is characterized in that: said card sender cabinet length and is located at 4m place, tollbooth the place ahead between 1.2 meters~1.8 meters.
Compared with prior art; The utility model is through being provided with two ground coils on the track; Thereby can set the various places coil through Control Software and form logical relation each other, solve the vehicle of getting visa card, can only obtain the chance of a visa card; Get the incident of visa card again if take to move backward, the card sender system no longer responds.The utility model can effectively be realized preventing the phenomenon of the many card takings of malice of moveing backward, thereby practice thrift the operation management expense.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of card sender prevent to move backward device of many card takings; Tollbooth the place ahead is provided with the card sender cabinet; The tollbooth rear is provided with electric railing; Track under the said electric railing is provided with counting ground coil Q3, and the track of card sender cabinet side is provided with triggers ground coil Q1, also is provided with anti-reverse ground coil Q2 behind the triggering ground coil Q1.Anti-reverse ground coil Q2 is located at and triggers 250mm place behind the ground coil Q1.Anti-reverse ground coil Q2 is the interior toroid winding of ground cutting groove that is embedded in wide 6~8mm, dark 60~100mm with triggering ground coil Q1, and toroidal laterally wide 2.4 meters, vertical wide 1.2M.Card sender cabinet length and is located at 4m place, tollbooth the place ahead between 1.2 meters~1.8 meters.
Principle of work: at first at first be pressed onto the first cover ground coil Q1 to the vehicle that gets into the track, the ground coil Q2 that is pressed onto for the second time leaves the track and is pressed onto ground coil Q3.Logical relation between it can lock same vehicle after getting visa card through card sender, and the card taking once more of moveing backward is invalid NO.The logical organization of many card takings of preventing to move backward is as shown in the table:
(1) go up shown in the table sequence number 1: vehicle gets into the track for the first time, pushes down ground coil Q1 and Q2Q, and automatic card dispenser sends visa card YAS, and vehicle is through ground coil Q3, electric railing vehicle through after fall card sender system clear " 0 " automatically; The card sender system gets into next circulation.
(2) go up shown in the table sequence number 2: vehicle leaves ground coil Q1, is present in ground coil Q2, when electric railing Q3 treats that vehicle passes through, and card sender system lock NO, the visa card of not redispatching.
(3) go up shown in the table sequence number 3: vehicle leaves ground coil Q1, Q2, and when electric railing Q3 treated that vehicle passes through, card sender system lock NO no longer possibly send visa card.
(4) go up shown in the table sequence number 4: vehicle at first is present in ground coil Q2 for 2 times, does not also arrive ground coil Q1, and when electric railing Q3 treated that vehicle passes through, card sender system lock NO no longer possibly send visa card.
(5) go up shown in the table sequence number 5: vehicle is present in ground coil Q2, Q1 for 2 times, and when electric railing Q3 treated that vehicle passes through, card sender system lock NO no longer possibly send visa card.
(6) go up shown in the table sequence number 6: vehicle leaves ground coil Q2 for 2 times, is present in ground coil Q1 2 times, and when electric railing Q3 treated that vehicle passes through, card sender system lock NO no longer possibly send visa card.
(7) go up shown in the table sequence number 7: vehicle leaves ground coil Q2, Q1 for 2 times, and when electric railing Q3 treated that vehicle passes through, card sender system lock NO no longer possibly send visa card.
(8) go up shown in the table sequence number 8: vehicle returns 3 times and has ground coil Q1, does not also arrive ground coil Q2, and when electric railing Q3 treated that vehicle passes through, card sender system lock NO no longer possibly send visa card.
(9) go up shown in the table sequence number 9: vehicle returns 3 coil Q1, Q2, and when electric railing Q3 treated that vehicle passes through, card sender system lock NO no longer possibly send visa card.
(10) go up shown in the table sequence number 10: vehicle leaves ground coil Q1, Q2 for 3 times, and clear " 0 " the card sender system of electric railing Q3 gets into next circulation.
Can find out that through above description vehicle gets into the track and gets visa card, have only a kind of maybe, and vehicle first order push down ground coil Q1 and Q2, can realize just during parking that button gets visa card.Every first not according to having triggered the ground coil in proper order, the card sender system automatically locks; Triggered ground coil Q1 or Q2 every (containing 2 times) more than 2 times; The card sender system automatically locks; No longer respond the secondary button and get visa card (ticket) requirement, only pass through back system clear " 0 " at the electric railing rolling stock, the card sender system could get into next circulation; Recover normal function of sending visa card, prevent effectively that repeatedly button gets the cheating of visa card.
