Alternatively, treatment circuit 1108 can correct parking space state in the following manner: judge whether drive current reaches locked rotor current level, if drive current reaches locked rotor current level, then parking space state is corrected to seizure condition.
Locked rotor current refers to the drive current that motor-drive circuit 1104 exports when motor 1200 is in locked rotor condition.As mentioned above, when motor 1200 is in locked rotor condition, the value of drive current can increase, and such as, it may increase to the several times of the drive current received when motor 1200 normally works.Like this, a current threshold can be preset, as the value distinguishing locked rotor current.Can by drive current compared with this current threshold, if drive current is greater than this current threshold, then can think that drive current now reaches locked rotor current level, motor 1200 is in locked rotor condition.Certainly, the current range limited by multiple threshold value can also be set.If drive current is in this current range, then can think that drive current reaches locked rotor current level, motor 1200 is in locked rotor condition.In addition, can also monitor the value of drive current, if find that drive current increases suddenly from running current level, also can think that drive current now reaches locked rotor current level, motor 1200 is in locked rotor condition.
Fig. 2 illustrates that intelligent space lock receives workflow diagram when liter lock is ordered according to an embodiment of the invention.Below in conjunction with Fig. 1 and Fig. 2, this embodiment is described.
In step S210, intelligent space lock 1000 receives a liter lock order, and the treatment circuit 1108 namely in intelligent space lock 1000 receives a liter lock order.In step S220, treatment circuit 1108 can determine based on the parking space state signal from parking space state sensor 1102 whether parking space state is now idle condition.If parking space state is now idle condition, then perform step S230.In step S230, treatment circuit 1108 controls motor-drive circuit 1104 drive motors 1200 and works, and to drive blocking arm to rise, namely starts a liter lock.In blocking arm uphill process, if do not parked cars above intelligent space lock 1000, then it can rise to smoothly and rise lock position, position residing when namely blocking arm rises completely.If parked vehicle above intelligent space lock 1000, then blocking arm can be blocked in uphill process, and cause motor 1200 stall, drive current now reaches locked rotor current level.Therefore, in step S240, treatment circuit 1108 can judge whether drive current reaches locked rotor current level.If drive current does not reach locked rotor current level, then in step S280, blocking arm rises to and rises lock position.If drive current reaches locked rotor current level, then in step S260, parking space state is corrected to seizure condition.In addition, in step S250 and step S270, can also perform some other operation, these will hereinafter be described.Finally, at the end of above flow process, intelligent space lock 1000 can get back to holding state, see step S290.
As described above, the parking space state accuracy of detection of parking space state sensor cannot reach 100%.If parking space state sensor 1102 does not detect the vehicle parked above intelligent space lock 1000, then when in blocking arm uphill process, the vehicle of top may be encountered, cause motor 1200 stall.In time parking space state can be corrected to seizure condition based on locked rotor current, thus can know and in fact parked vehicle above intelligent space lock 1000.Like this, blocking rotation measure can be taked in time, such as, blocking arm be fallen, thus reduce the damage to vehicle or berth lock.
Alternatively, treatment circuit 1108 can be further used for: when blocking arm rises, and judges whether drive current reaches locked rotor current level, if drive current reaches locked rotor current level, then control motor-drive circuit 1104 drive motors 1200 to work, return to drive blocking arm and fall lock position; When blocking arm declines, judge whether drive current reaches locked rotor current level, if drive current reaches locked rotor current level, then control motor-drive circuit 1104 drive motors 1200 and work, return to drive blocking arm and rise lock position.
Referring back to Fig. 2, in step S250, control motor-drive circuit 1104 drive motors 1200 by treatment circuit 1108 and work, return to make blocking arm and fall lock position.
If there is vehicle above intelligent space lock 1000, blocking arm is blocked in uphill process, then blocking arm can be fallen.Like this, motor 1200 can be avoided to be in locked rotor condition for a long time and to be burned, also can reduce the damage that intelligent space lock 1000 causes with the collision of vehicle.Due to some fortuitous events, also likely there are some obstructions in the base of intelligent space lock 1000, cause blocking arm to drop to and fall lock position, position residing when namely blocking arm is fallen completely.Therefore, in blocking arm decline process, if find that it is blocked, motor 1200 is in locked rotor condition, then rise lock position before blocking arm can being risen to equally.
Alternatively, treatment circuit 1108 can be further used for judging whether parking space state changes into idle condition from seizure condition, if parking space state is changed into idle condition from seizure condition and do not receive a liter lock order in scheduled time slot, then control motor-drive circuit 1104 drive motors 1200 after a predetermined period to work, rise to drive blocking arm.The present embodiment can realize parking stall AutoLock feature in some application scenarios.
Alternatively, treatment circuit 1108 can be safeguarded and represent the parking space state information of parking space state, such as, parking space state information be stored in be connected with treatment circuit 1108 or in the memory for the treatment of circuit 1108 inside.As mentioned above, parking space state sensor 1102 (such as one minute) is detected at set intervals parking space state signal can be sent to treatment circuit 1108.Therefore, treatment circuit 1108 can determine a parking space state at set intervals.Like this, the parking space state detected for twice may change.If parking space state changes into idle condition from seizure condition, illustrate that the vehicle be originally parked on parking stall has sailed out of this parking stall.Now, if do not receive a liter lock order in the given time, then treatment circuit 1108 can control blocking arm rise automatically.Like this, parking stall user can be avoided to be risen by blocking arm owing to forgetting and cause parking stall by situation that other people take.
Alternatively, control circuit 1100 may further include wireless communication interface, and for receiving the control command of the associate device from intelligent space lock, control command is also sent to treatment circuit by start treatment circuit.Fig. 3 illustrates the schematic block diagram of intelligent space lock and associate device according to an embodiment of the invention.Motor 3200 shown in Fig. 3, parking space state sensor 3102, motor-drive circuit 3104, current detection circuit 3106 and treatment circuit 3108 are corresponding with the motor 1200 shown in Fig. 1, parking space state sensor 1102, motor-drive circuit 1104, current detection circuit 1106 and treatment circuit 1108, repeat no more.
