Summary of the invention
The object of the invention is to the deficiency existed for prior art, provide a kind of lift-sliding parking equipment increasing automatic fence and checkout gear, to improve intelligentized control method level and the security of operation of equipment.
Basic technology scheme of the present invention is: a kind of lift-sliding parking equipment increasing automatic fence and checkout gear, is characterized in that: described lift-sliding parking equipment is based on lift-sliding parking equipment general at present; Described Universal lifting side-sliding packing equipment must possess following configuration: by monolithic processor controlled/human-computer interface device of swiping the card, the control device built by PLC or single-chip microcomputer or single board computer, to be provided with to prevent people's car to be strayed into correlation checkout gear at vehicle in and out port; Wherein, correlation checkout gear normally, all sends skip signal at the correlation routing restoration of its correlation passage of object masks and crested; The automatic fence of described increase be arranged on parking apparatus come in and go out deck each vehicle in and out port just before facade position, controlled by the human-computer interface device of former Universal lifting side-sliding packing equipment or control device, be in closed condition or opening; Described automatic fence is in closed condition and will makes personnel and vehicle can not from buttoned-up automatic column location in/out; Described automatic fence is in opening and will makes personnel and vehicle can from the automatic column location in/out of having opened; When equipment is in normal static standby state, all automatic fence are all in closed condition, prevent people/car to be strayed into; When user carries out the operation of storage/access car, first relevant vehicle-containing is scheduled to the discrepancy deck of equipment; Then, opening changed into by the just right automatic fence of this vehicle-containing, makes personnel and vehicle to enter vehicle-containing in the position of this automatic fence from track or to roll track away from from vehicle-containing; The everything of user's storage/access car operation completes, and this automatic fence changes into closed condition, the normal static standby state of device replied; When only having all automatic fence to be all in closed condition, equipment just can perform the management and running instruction of vehicle-containing; The checkout gear of described increase for install at least one ultrasonic detection device on each block vehicle-containing, and this ultrasonic detection device can be wireless or wired forms, object masks detected or can't detect object masks, all send correlation behavior signal; Ultrasonic detection device by former Universal lifting side-sliding packing equipment human-computer interface device or control device controls, carry out collection and the process of coherent signal; Vehicle sails into the process that vehicle-containing parks from track, and the correlation checkout gear that vehicle in and out port place installs detects that vehicle enters to cover to leave to vehicle and covers; The ultrasonic detection device that vehicle-containing is installed detect vehicle from enter its detection range to complete crested; Vehicle rolls away from the process in track from vehicle-containing, and the correlation checkout gear that vehicle in and out port place installs detects that vehicle enters to cover to leave to vehicle and covers; The ultrasonic detection device that vehicle-containing is installed detects that vehicle is from complete crested to leaving its detection range gradually; Therefore, the process that user's bicycle parking, i.e. vehicle sail vehicle-containing into from track and user picks up the car, namely vehicle rolls track away from from vehicle-containing, will trigger above-mentioned correlation checkout gear and above-mentioned ultrasonic detection device produces regular signal intensity; By analysis, the state of vehicle on vehicle-containing can be differentiated.
By monolithic processor controlled/human-computer interface device of swiping the card, the control device built by PLC or single-chip microcomputer or single board computer, to be provided with to prevent people's car to be strayed into correlation checkout gear at vehicle in and out port, these are all the basic configuration of current Universal lifting side-sliding packing equipment.And fence is the facility that the present invention increases automatically.As mentioned above, automatic fence is arranged on the just front facade position of each vehicle in and out port of parking apparatus discrepancy deck.When automatic fence is in opening, palpus ensures its headway size conforms related specifications, span width is of a size of maximum.If carry out totally-enclosed to vehicle in and out port after installing automatic fence, then automatically the width dimensions of fence and vehicle in and out port width similar, advise that automatic fence is can the rectangular frame member of vertical lifting/lowering; The primary structure member of this framing component can be aluminium extruded sections or steel profile, and the material in centre position can be aluminium net or steel mesh.If automatically fence only carries out symbolisticly closing to vehicle in and out port, only play and intercept automobile ingress/egress and play warning function, then advise automatic fence be width dimensions be less than vehicle in and out port width, can the rectangular frame member of vertical lifting/lowering; Or, be can vertical lifting/lowering or swing a warning rail of lifting/lowering or even a warning sign.Can the automatic fence of vertical lifting/lowering can be have guide rail to clamp the/lifting of spacing restraint of liberty degree or without guide rail clamping/spacing being freely elevated, it be elevated by motor+rectilinear motion drive unit drives.And rectilinear motion driver element can be gear+rack drives or the common version such as rope sheave+wire rope traction or sprocket wheel+chain traction.Due to the power of motor very little (only needing tens watts), be configured with by monolithic processor controlled human-computer interface device by former Universal lifting side-sliding packing equipment or be configured with the control device built by PLC or single-chip microcomputer or single board computer and output signal control relay or contactor drives, belonging to general control form.
Ultrasonic detection device is the facility that basic technology scheme of the present invention increases.The ultrasonic detection device of above-mentioned wired forms or wireless is all common version.For this basic technology scheme, adopt the ultrasonic detection device of wired forms, its advantage is can by control system detection trigger, and the state read is the immediate status of vehicle on vehicle-containing, but shortcoming needs wiring; Adopt the ultrasonic detection device of wireless, its advantage is to detect and send detect consequential signal without the need to wiring, timing; Shortcoming once regularly detect before to be state that control system is read be the vehicle that obtains in the state of vehicle-containing not necessarily current real-time status (maximum delay error is the spacing that a timing detects).But, due to vehicle sail into, the time of rolling away from needed for vehicle-containing is at least tens seconds, as long as rationally arrange the time interval (being such as 5 to 8 seconds) that timing detects, then accuracy of detection is enough.In addition, adopt the ultrasonic detection device of wireless usually to need supporting installation receive data by wireless/retransmission unit, the detection data of wireless ultrasonic checkout gear are received by this device, are then forwarded to related Control System and adopt.Certainly, this device also accessible site within control system.
At present, lift-sliding parking equipment adopts IC-card to bind the control mode of vehicle-containing numbering usually, i.e. the corresponding one piece of vehicle-containing of physics numbering of one piece of IC-card.In such a mode, suppose that equipment is in normal static standby state, all automatic fence are all in closed condition; User's being operating as stored in vehicle of this basic technology scheme: user swipes the card in man-machine interface; Equipment carries out corresponding vehicle-containing scheduling, extremely required vehicle-containing and is dispatched to discrepancy deck; Opening changed into by the automatic fence just right with this vehicle-containing position; User drives enter vehicle-containing and park appropriate; Section at this moment, first being that the correlation checkout gear that equipment access is installed detects that vehicle covers, is then that the ultrasonic detection device that vehicle-containing is installed detects that vehicle enters and crested, is finally that correlation checkout gear that equipment access is installed detects that vehicle leaves, no longer covers the ultrasonic detection device that vehicle-containing is installed and then continue to detect and to be covered by vehicle; User's bicycle parking end of operation, leave equipment region, the correlation checkout gear that equipment access is installed has detected object masks respectively and has left, no longer covers this two processes (this object is user's body under normal circumstances); So far, user's bicycle parking has operated.Certainly, for avoiding the interference being subject to other factors, such as there are special circumstances: user did not also leave equipment region at that time, above-mentioned " equipment access install correlation checkout gear object masks detected and leave, no longer cover this two processes " is in fact that another one people walks about near equipment access and the correlation checkout gear of trigger equipment access installation sends caused by signal, then apparatus control system can be caused to judge by accident.The detection signal of safe solution to be automatic fence down maneuver after user's bicycle parking has operated be not correlation checkout gear installed by equipment access triggers, but specify user after completing bicycle parking operation, walking out equipment region, need arrive human-computer interface device and again swipe the card, this swipe the card namely really confirm that user leaves, trigger equipment control system controls automatic fence decline corresponding to vehicle-containing that this user operated just now, to closed condition; Parking apparatus is returned to normal static standby state.Operation that aforesaid operations is called " user's bicycle parking secondary is swiped the card ".When user's bicycle parking operation first time swipe the card come into force after until the second time of this user is swiped the card, operation acknowledgement leaves this time period, the operation of swiping the card of other users will be ignored by apparatus control system until apparatus control system confirm user complete bicycle parking operation, walk out equipment region.Or the operation of swiping the card of other users is considered as the follow-up execution instruction of equipment and automatically performs in order after equipment recovers normal rest state.If the bicycle parking of user operate in first time swipe the card, complete bicycle parking after forget that the second time of carrying out leaving confirmation is swiped the card, equipment management personnel is then needed to carry out unlocking operation or input specifies unlocking pin to carry out unlocking operation, to guarantee safety after needing other user card punchings.
Under the IC-card binding vehicle-containing numbering scheme of lift-sliding parking equipment, the user of this basic technology scheme takes out vehicle operating and is: swipe the card in man-machine interface; Equipment carries out corresponding vehicle-containing scheduling; Be dispatched to discrepancy deck to required vehicle-containing, opening changed into by the automatic fence just right with this vehicle-containing position; User enters vehicle-containing and vehicle is outputed, leaves equipment region; Section at this moment, first be correlation checkout gear that equipment access is installed detect that personnel walk about (namely user enters) cover and no longer cover, then covered by the vehicle rolled away from, be then that the ultrasonic detection device that vehicle-containing is installed detects that vehicle leaves, no longer covers two processes, be finally that the correlation checkout gear of equipment access installation detects that outgoing vehicles leaves, no longer cover the ultrasonic detection device that vehicle-containing is installed and then continues to detect that vehicle leaves, no longer cover; So far, user's operation of picking up the car completes.The differentiation operated with user's bicycle parking is different: user leaves together with vehicle as driver, because correlation checkout gear to the vehicle installed from vehicle screening arrangement access leaves, no longer covers, occur when the required time walks about much larger than personnel cover to leaving, no longer time of needing of shelter, namely both can clearly distinguish; And the ultrasonic detection device that vehicle-containing is installed continues to detect and to cover without vehicle after vehicle leaves; To the reasonable genetic sequence of above signal and the analysis of time-wise separation, equipment region can be left with identification vehicle and user by correct decision.Therefore, even if adopt the operator scheme of " user's bicycle parking secondary is swiped the card ", user picks up the car and is also directly automatically confirmed by apparatus control system without the need to carrying out the second time safety verification of swiping the card, to reduce operating procedure, the saving user operation required time of user.Certainly, also can specify that user picks up the car also will carry out second time and swipe the card and carry out safety verification.When equipment confirms that vehicle and automatic fence corresponding to user leaves, this user of trigging control operated just now vehicle-containing decline, to closed condition; Parking apparatus is returned to normal static standby state.In like manner, when user pick up the car first time of operation swipe the card come into force after until apparatus control system confirms that user and vehicle have left this time period of equipment region, the operation of swiping the card of other users will be ignored by apparatus control system until apparatus control system confirms that user and vehicle leave equipment region.Or the operation of swiping the card of other users is considered as the follow-up execution instruction of equipment and automatically performs in order after equipment recovers normal rest state.
Because this basic technology scheme is provided with ultrasonic detection device on each block vehicle-containing of parking apparatus, therefore user's " arbitrarily parking " pattern that IC-card no longer binds vehicle-containing numbering can be realized.In such a mode, suppose that equipment is in normal static standby state, all automatic fence are all in closed condition; User's being operating as stored in vehicle of this basic technology scheme: user swipes the card in man-machine interface (this card can be send in advance, also can be send at random in entrance); Due to equipment can not search mate with this IC-card number vehicle-containing, can judge that user is that bicycle parking operates, so carry out unloaded sweep scheduling; Be dispatched to discrepancy deck to unloaded sweep, opening changed into by the automatic fence just right with this vehicle-containing position; User drives enter vehicle-containing and park appropriate; Section at this moment, first being that the correlation checkout gear that equipment access is installed detects that vehicle covers, is then that the ultrasonic detection device that vehicle-containing is installed detects that vehicle enters and crested, is finally that correlation checkout gear that equipment access is installed detects that vehicle leaves, no longer covers the ultrasonic detection device that vehicle-containing is installed and then continue to detect and to be covered by vehicle; User's bicycle parking end of operation, leave equipment region, the correlation checkout gear that equipment access is installed has detected object masks respectively and has left, no longer covers this two processes (this object is user's body under normal circumstances); So far, user's bicycle parking has operated, and the IC-card numbering that equipment was swiped the card user just now number with the vehicle-containing just now stopped and deposited in the lump, as user pick up the car operation swipe the card time apparatus control system search for information.Operate similar with user's bicycle parking of aforesaid " IC-card binding vehicle-containing " pattern, for avoiding the interference being subject to other factors, aforesaid " user's bicycle parking secondary is swiped the card " method can be taked, namely user's bicycle parking operated after automatic fence down maneuver be not the correlation checkout gear installed by equipment access detection signal trigger, but specify that user completes bicycle parking operation, after walking out equipment region, human-computer interface device need be arrived again swipe the card, this i.e. real confirmation user that swipes the card leaves, the automatic fence that trigger equipment control system controls vehicle-containing that this user operated just now corresponding declines, to closed condition, parking apparatus is returned to normal static standby state.As hereinbefore, when user's bicycle parking operation first time swipe the card come into force after until the second time of this user is swiped the card, operation acknowledgement leaves this time period, the operation of swiping the card of other users will be ignored by apparatus control system until apparatus control system confirm user complete bicycle parking operation, walk out equipment region.Or the operation of swiping the card of other users is considered as the follow-up execution instruction of equipment and automatically performs in order after equipment recovers normal rest state.If the bicycle parking of user operate in first time swipe the card, complete bicycle parking after forget that the second time of carrying out leaving confirmation is swiped the card, equipment management personnel is then needed to carry out unlocking operation or input specifies unlocking pin to carry out unlocking operation, to guarantee safety after needing other user card punchings.
Under user's " arbitrarily parking " pattern that the IC-card of lift-sliding parking equipment no longer binds vehicle-containing numbering, the user of this basic technology scheme takes out vehicle operating and is: user swipes the card in man-machine interface; Namely equipment carry out searching for, obtaining corresponding vehicle-containing numbering according to the IC-card numbering of swiping the card, and then carries out the scheduling of corresponding vehicle-containing; Be dispatched to discrepancy deck to required vehicle-containing, opening changed into by the automatic fence just right with this vehicle-containing position; User enters vehicle-containing and vehicle is outputed, leaves equipment region; Section at this moment, first be correlation checkout gear that equipment access is installed detect that personnel walk about (namely user enters) cover and no longer cover, then covered by the vehicle rolled away from, be then that the ultrasonic detection device that vehicle-containing is installed detects that outgoing vehicles leaves, no longer covers two processes, be finally that the correlation checkout gear of equipment access installation detects that vehicle leaves, no longer cover the ultrasonic detection device that vehicle-containing is installed and then continues to detect that vehicle leaves, no longer cover; So far, user's operation of picking up the car completes.With the user of aforesaid " IC-card binding vehicle-containing " pattern pick up the car operate identical, even if adopt the operator scheme of " user's bicycle parking secondary is swiped the card ", user picks up the car and is also directly automatically confirmed by apparatus control system without the need to carrying out the second time safety verification of swiping the card, to reduce operating procedure, the saving user operation required time of user.Certainly, also can specify that user picks up the car also will carry out second time and swipe the card and carry out safety verification.When equipment confirms that vehicle and automatic fence corresponding to user leaves, this user of trigging control operated just now vehicle-containing decline, to closed condition; That deposit before equipment, corresponding with aforementioned operation vehicle-containing IC-card is numbered and is cleared; Parking apparatus is returned to normal static standby state.As hereinbefore, when user pick up the car first time of operation swipe the card come into force after until apparatus control system confirms that user and vehicle have left this time period of equipment region, the operation of swiping the card of other users will be ignored by apparatus control system until apparatus control system confirms that user and vehicle leave equipment region.Or the operation of swiping the card of other users is considered as the follow-up execution instruction of equipment and automatically performs in order after equipment recovers normal rest state.
No longer bind user's " arbitrarily stop " pattern of vehicle-containing numbering at the IC-card of lift-sliding parking equipment under, if more than one group of the parking apparatus of parking area, then user or there will be forgets specifically in the puzzlement which group equipment stops.Therefore, function (namely looking into storing cycle positional information from IC-card) becomes reasonable demand " oppositely to seek car ".
If parking area by organizing parking apparatus and these equipment have formed LAN (can be cable network or wireless network) more, then " oppositely seeking car " device of swiping the card can be set on this LAN, after user card punching, namely this " oppositely seeking car " device accesses all devices group by LAN, (comprising equipment group # and vehicle-containing numbering) then shows to inquire the vehicle position information of correspondence, goes to the position specifically parked cars to operate correctly to guide user.
Under the above-mentioned IC-card at lift-sliding parking equipment no longer binds user's " arbitrarily stop " pattern of vehicle-containing numbering, after user's bicycle parking operate, the IC-card read of swiping the card numbered and deposited by equipment; User pick up the car operation time complete after, original equipment deposit IC-card numbering be cleared.
Above way also can change into swipes the card when user's bicycle parking operates, and after equipment is determined as bicycle parking, the information such as the vehicle-containing numbering of distributing for this user's vehicle is write (comprising equipment group #) storage area of IC-card; Pick up the car after operation completes user, the vehicle-containing numbering that IC-card is deposited and group # information empty.The storing cycle positional information (comprising equipment group # and vehicle-containing numbering) making IC-card corresponding due to this processing mode writes IC-card, therefore " oppositely seeking car " device only need read relevant information when swiping the card and shows and without the need to accessing each group of parking apparatus, namely respectively organize between parking apparatus without the need to networking.The benefit that IC-card writes storing cycle positional information is also that equipment has a power failure or breaks down, and car stowage positional information also can not occur and lose; Meanwhile, the written information of IC-card can also comprise the time of bicycle parking of swiping the card and swipe the card the time of picking up the car, time of parking in mechanical parking stall for accurate Calculation vehicle for calculating charge.
Above-described " oppositely seeking car " operation can further expand, increase the function being called " scheduling of reservation vehicle-containing ".The storing cycle positional information of device of specifically " oppositely seeking car " display after user confirms, form the instruction of a scheduling vehicle-containing, apparatus control system automatically performs when confirmation equipment is in normal static standby state.
Based on the above basic technology scheme, further, described a kind of a kind of Technological improvement plan increasing the lift-sliding parking equipment of automatic fence and checkout gear, is characterized in that: the installation site of the ultrasonic detection device of described increase change into each vehicle in and out port at equipment ground, between correlation checkout gear and vehicle-containing, position is installed; Or, change into and installing at the front beam lower position of each vehicle in and out port of equipment; Or, change into and installing at the lower position of described automatic fence; No matter be take which kind of installation form, all to ensure vehicle-containing normal static time, vehicle vehicle-containing normally leave standstill time and vehicle park beyond equipment region or travel time, this ultrasonic detection device is all in the state that non-detected object covers, in order to avoid produce wrong report.
The concrete enforcement of this Technological improvement plan and aforementioned to install ultrasonic detection device on vehicle-containing basically identical, because, the position of two scheme installation ultrasonic detection devices is all be positioned at equipment parking area in fact, user's bicycle parking operation and user pick up the car, and to operate the Changing Pattern of all detection signals caused all identical, distance size only due to installation site and correlation checkout gear is variant, so slightly different on the timing intervals of signal.Therefore, do not repeat here.The difference of two schemes is also, aforementionedly on vehicle-containing, installs ultrasonic detection device, the quantity of required ultrasonic detection device equals equipment vehicle-containing quantity, relatively many, but can judge vehicle intuitively whether on vehicle-containing; And the quantity of ultrasonic detection device needed for this Technological improvement plan equals equipment vehicle in and out port quantity, relatively less, but the signal analysis that can only be read by apparatus control system during user's storage/access vehicle operating judges vehicle whether on vehicle-containing, and work out accordingly, upgrade corresponding vehicle-containing bicycle parking list.
Based on the above basic technology scheme, further, described a kind of Technological improvement plan increasing the lift-sliding parking equipment of automatic fence and checkout gear, is characterized in that: the checkout gear of described increase is the ground of each vehicle in and out port at equipment, side, adjacent track, with installing one sense checkout gear; This ground sense checkout gear detects that metal object covers or can't detect metal object and covers, all sends correlation behavior signal; Feel checkout gear by the human-computer interface device of former Universal lifting side-sliding packing equipment or control device controls, carry out collection and the process of coherent signal describedly; Vehicle sails into the process that vehicle-containing parks from track, and the ground sense checkout gear being arranged on equipment vehicle in and out port ground detects that vehicle starts to enter its detection range to being covered by vehicle completely, being finally that vehicle leaves its detection range; Vehicle rolls away from the process in track from vehicle-containing, and the ground sense checkout gear being arranged on equipment vehicle in and out port ground detects that vehicle starts to enter its detection range to being covered by vehicle completely, being finally that vehicle leaves its detection range; The process that user's bicycle parking, i.e. vehicle sail vehicle-containing into from track and user picks up the car, namely vehicle rolls track away from from vehicle-containing, is arranged on the correlation checkout gear that the ground sense checkout gear on equipment vehicle in and out port ground and former Universal lifting side-sliding packing equipment install at vehicle in and out port place produces regular signal by triggering; By analysis, the state of vehicle on vehicle-containing can be differentiated.
The Cleaning Principle of ground sense checkout gear is that metal object (this case is vehicle) can detect and send signal when being in detection range.The concrete enforcement of this Technological improvement plan and aforementioned to install ultrasonic detection device similar in position between correlation checkout gear and vehicle-containing, does not repeat here.
Detailed description of the invention
The following stated is only the preferred embodiment embodying the principle of the invention, does not therefore limit protection scope of the present invention.
Be illustrated in figure 1 the lift-sliding parking equipment side view of the automatic fence of increase of the present invention and checkout gear; Fig. 2 is the top view of Fig. 1.Comprehensive two views are known: equipment is provided with correlation checkout gear 3 in close side, track, its detection medium is to ejected wave 3-1; Illustrate automatic fence 1 and be in opening, inside, space 7, equipment parking stall is placed with vehicle-containing 5, has vehicle-containing to be sky, also to have vehicle 6 to be parked on vehicle-containing 5.Whether the effect of correlation checkout gear 3 detects to have object to block ejected wave.When vehicle 6 enters vehicle-containing 5 from track, first correlation checkout gear 3 detect the entering of vehicle 6, be then lasting crested, be finally that vehicle 6 leaves.When vehicle 6 rolls track away from from vehicle-containing 5, first correlation checkout gear 3 detect the entering of vehicle 6, be then lasting crested, be finally that vehicle 6 leaves.Clearly, vehicle 6 enters vehicle-containing 5 and rolls these two kinds of distinct run action of track with vehicle 6 away from from vehicle-containing 5 from track, under the detection of correlation checkout gear 3, present identical result.Therefore, to grasp the realistic operation of vehicle, needing to increase other checkout gears and carrying out mutual cooperation.Four kinds of mounting meanss of checkout gear are shown in figure.Wherein, the first is all install ultrasonic detection device to the third; 4th kind is install ground-sensor.
The first mounting means of ultrasonic detection device is that ultrasonic detection device 2-3 is arranged on each block vehicle-containing 5; If vehicle 6 enters vehicle-containing 5 from track, first correlation checkout gear 3 will detect the entering of vehicle 6, then be that correlation checkout gear 3 continues crested; When vehicle 6 enters vehicle-containing 5, the ultrasonic detection device 2-3 being arranged on vehicle-containing 5 detects the entering of vehicle 6, is then that ultrasonic detection device 2-3 continues crested; To vehicle 6 completely access arrangement region, no longer cover correlation checkout gear 3, correlation checkout gear 3 replys conducting; Until vehicle 6 enters vehicle-containing 5 completely, ultrasonic detection device 2-3 is still covered by vehicle 6.If vehicle 6 rolls track away from from vehicle-containing 5, first the ultrasonic detection device 2-3 being arranged on vehicle-containing 5 detect the leaving of vehicle 6, be then that correlation checkout gear 3 is covered by vehicle 6 and is continued until that vehicle 6 leaves equipment region completely, no longer covers correlation checkout gear 3, correlation checkout gear 3 replys conducting.Clearly, increase and install ultrasonic detection device 2-3, coordinate correlation checkout gear 3, vehicle 6 enters vehicle-containing 5 and vehicle 6 and rolls these two actions of track away from from vehicle-containing 5 and can clearly distinguish from track.
The second mounting means of ultrasonic detection device be each vehicle in and out port changed at equipment ground, between correlation checkout gear 3 and vehicle-containing 5, position is installed, and is illustrated ultrasonic detection device 2-2.If vehicle 6 enters vehicle-containing 5 from track, first correlation checkout gear 3 will detect the entering of vehicle 6, then be that correlation checkout gear 3 continues crested; When vehicle 6 continues to enter, ultrasonic detection device 2-2 detects vehicle 6 and continues crested; To vehicle 6 completely access arrangement region, no longer cover correlation checkout gear 3, correlation checkout gear 3 replys conducting; To vehicle 6 be about to enter vehicle-containing 5 completely, ultrasonic detection device 2-2 detects leaving of vehicle 6.If vehicle 6 rolls track away from from vehicle-containing 5, first ultrasonic detection device 2-2 detects vehicle 6 and continues to be covered by vehicle 6, is then that correlation checkout gear 3 detects vehicle 6 and continues to be covered by vehicle 6; Vehicle 6 continues the detection range rolling, leave ultrasonic detection device 2-2 away from; Finally, vehicle 6 leaves equipment region completely, no longer covers correlation checkout gear 3, correlation checkout gear 3 replys conducting.Clearly, increase and ultrasonic detection device 2-2 is installed, coordinates correlation checkout gear 3, clearly can distinguish vehicle 6 equally and enter vehicle-containing 5 from track and vehicle 6 rolls these two actions of track away from from vehicle-containing 5.
The third mounting means of ultrasonic detection device changes into installing at the lower position of automatic fence, is illustrated ultrasonic detection device 2-1.And at the front beam lower position of each vehicle in and out port of equipment, ultrasonic detection device is installed, its effect is substantially identical with diagram ultrasonic detection device 2-1.The operation of the third mounting means of ultrasonic detection device is identical with aforementioned second way mounting means, does not repeat here.
4th kind of mounting means of ultrasonic detection device is the ground of each vehicle in and out port at equipment, side, adjacent track, install a ground sense checkout gear, be and feel checkout gear 4 illustratedly.Second, third kind of mounting means installing the ground sense operation of checkout gear 4 and aforementioned ultrasonic checkout gear is similar, does not repeat here.
