Description
Technical Field
The invention relates to the field of anti-theft locks, in particular to an anti-theft spring lock and a graphene anti-theft spring lock.
Background
The spring lock is the first choice equipment of resident's pickproof lock and office door lock, has advantages simple to use, with low costs, and the measure that strengthens spring lock security in the past, prevent that it from being tried out is the complexity that increases mechanical lock core. Taking the pin tumbler lock as an example, the pin tumbler lock has been updated by three generations, namely an A-level lock, a B-level lock and an ultra B-level lock, the mechanical structure of the pin tumbler lock is more and more complicated, and the number of parts of the ultra B-level lock which appears at present newly exceeds 100. Although the difficulty of the technical trial development is higher, the reliability is reduced along with the increase of the number of the parts.
The basic principle of a spring lock is that the function of controlling the opening of a lock is achieved by adjusting the relative position of the interface of two sections of springs (called inner springs and outer springs, also called key code springs and locking springs) in a lock core and the interface of an inner lock core and an outer lock core. Due to the unlocking principle of the spring lock, the spring lock has the fatal defect that the spring lock can be opened by adopting methods such as 'tin foil unlocking' and the like.
The existing methods for preventing the theft of the pin tumbler lock through electric control are roughly as follows: 1. the MCU learns and stores the shape of the key, the movement track when the key is inserted and the like, and if the actual detected shape is different from the movement track learned and stored in advance, the key is considered to be illegally unlocked; 2. detecting the stay time of the key in the lock, and if the stay time is too long, determining that the lock is illegally unlocked; 3. by detecting whether the vibration amplitude of the lock exceeds a certain range, if the vibration amplitude is too large, the lock is considered to be illegally unlocked.
The detection anti-theft method is easy to cause the condition of false detection because the detection logic is too rough. For example, the situation of false alarm caused by the fact that accidental unlocking at one time is different from the prior unlocking habit or unlocking by other family members easily occurs in the method 1; in the 2 nd method, foreign matters can enter the lock, or false alarm can be caused by long unlocking time due to rusting in the lock; the 3 rd method may have a situation where the knock is too great resulting in a false alarm. Therefore, a new cylinder anti-theft lock is needed to solve the above-mentioned drawbacks.

fig. 2 is a structural diagram of a graphene anti-theft cylinder lock according to a seventh embodiment of the present invention; the device comprises a 10-cylinder, an 11-piston and a 12-graphene pressure sensor.
Detailed Description
The first embodiment is as follows: in the anti-theft pin tumbler lock of the present embodiment, a pressure sensor 8 is disposed at the lower part of at least one outer pin tumbler 6, at least one photoelectric sensor 7 is disposed around any one outer pin tumbler 6 inside, and a processor (not shown in the figure) connected to the pressure sensor 8 and the photoelectric sensor 7 is disposed outside the lock cylinder, and the processor is configured to determine whether an illegal unlocking behavior occurs according to the time sequence characteristics of signals detected by the pressure sensor and the photoelectric sensor and the signal value detected by the pressure sensor.
Specifically, the invention judges whether illegal unlocking behavior occurs or not through a pressure sensor arranged at the lower part of the outer pin and a photoelectric sensor of the inner lock cylinder. The pin tumbler comprises an inner pin tumbler and an outer pin tumbler which are mutually contacted, wherein the outer pin tumbler refers to a part contacted with a key, and the inner pin tumbler is a part contacted with a spring in a pin slot. The periphery of any outer pin can be the position of the outer pin or other positions close to the outer pin, so that the outer pin does not block the light emitted by the photoelectric sensor. The processor can be arranged in the inner lock cylinder, the outer lock cylinder or the lock structure, and the processor only needs to be electrically connected with components such as a sensor and the like for executing the judging step.
The normal unlocking process is as follows: a user inserts the key 9 into the inner lock cylinder 2, the pins 6 are lifted by the teeth of the key 9 in the process that the key 9 moves to the deep part of the inner lock cylinder 2, and when all the pins 6 are lifted by the teeth, the key 9 reaches the deepest part of the inner lock cylinder 2. When the key 9 reaches the deepest part of the inner lock cylinder 2, the height position of the marble 6 is not changed and only rotates along with the key 1.
The process of using the universal unlocking device or the iron wire and other unlocking equipment is as follows: the method is characterized in that firstly, an unlocking device is inserted into an inner lock cylinder 2, then a part in the unlocking device is used for lifting a marble 6, namely, the process that a key 9 reaches the deep part of the inner lock cylinder 2 is obviously separated from the process that the marble 6 is lifted, and is not synchronously executed, because the process that the key 9 is not matched with a lock is determined by the intrinsic characteristic of illegal unlocking, and the illegal unlocking uses the key which is not matched with the lock, so that the fine adjustment is certainly needed after the unlocking device is inserted, and the effect of tooth pattern is simulated.
The photoelectric sensor 7 can use a combination of a laser transmitter and a laser receiver, namely, the laser receiver can receive laser under normal conditions, and the receiver can not receive the laser due to the shielding effect when the key is inserted, so that whether the key travels to a corresponding depth can be judged by whether the laser can be received. The positions of the laser transmitter and the laser receiver can be symmetrically arranged on two sides of the axis direction of the inner lock cylinder, namely, the insertion of a key can be detected.
The pressure sensor and the photoelectric sensor 7 can be provided in multiple numbers, first, 1 pressure sensor and 1 photoelectric sensor are taken as examples, the pressure sensor is arranged below the marble at the deepest position, the photoelectric sensor is arranged at a position near the marble at the deepest position (the position near the marble refers to a position slightly deep or shallow in the marble position, and the purpose is to prevent the marble from shielding laser light), the time when the photoelectric sensor detects an obstacle is recorded as t1, the time when the pressure sensor detects that a pressure value is larger than the gravity of the marble is recorded as t2, if the absolute value of the difference between t1 and t2 is smaller than a certain value, the two processes are considered to be simultaneously carried out, that is, reasonable unlocking can be judged, and if the absolute value is larger than a threshold value, the key insertion process and the marble lifting process are considered to be separated, that is.
And if the number of the pressure sensors and the photoelectric sensors is set to be plural, the accuracy of detection can be significantly increased. For example, if the number of the photoelectric sensors is multiple, the position of the key travel can be judged according to the sequence of the photoelectric sensors which are sequentially shielded, and if one of the photoelectric sensors is damaged, the anti-theft detection of the pin tumbler lock is not influenced. The same applies to the pressure sensors, and increasing the number of pressure sensors can increase the detection accuracy. In a preferred example, the pressure sensor should be preferentially arranged at the pin with the highest tooth height, because the pin with the highest tooth has a larger movement amplitude and is easier to detect.
The second embodiment is as follows: the first difference between the present embodiment and the specific embodiment is: the number of the photoelectric sensors 7 is 1, and the preset position is the position of the marble at the deepest part of the inner lock cylinder 2.
The beneficial effects of the embodiment are as follows: the purpose of detecting illegal unlocking can be achieved by using a group of photoelectric sensors, the cost is saved, and the position of the key reaching the end of the lock cylinder can be accurately judged by setting the preset position. It should be noted that "the position of the innermost pin of the inner lock cylinder" should ensure that the pin does not block the receiving portion of the photoelectric sensor.
Other steps and parameters are the same as those in the first embodiment.
The third concrete implementation mode: the present embodiment differs from the first or second embodiment in that: the number of the pressure sensors 8 is 1, the number of the photoelectric sensors 7 is 1, the pressure sensors 8 are arranged at the lower parts of the marbles 6 at the deepest part of the inner lock cylinder 2, and the photoelectric sensors 7 are arranged at the deepest part where the tail end of the key 9 can be inserted;
the processor includes:
the first detection unit is used for judging whether a receiving end of the photoelectric sensor detects an optical signal within a preset time threshold value when the pressure received by the pressure sensor is greater than the gravity of the marble, and if so, the processor sends out warning information.
According to the principle of the normal unlocking process in the first embodiment, in the normal unlocking process, when the marble 6 is lifted, the key 9 is in a fully inserted state, so that when the pressure sensor 8 detects a pressure change, whether the photoelectric sensor 7 detects a signal or not can be judged, and if the signal is not detected, the key 9 is in the deepest position and belongs to the normal unlocking process; if the laser signal can still be detected, that is, the key 9 is not located at the deepest position, it indicates that illegal unlocking may be performed by others using an unlocking tool such as a wire or the like, because the unlocking tool can unlock without being inserted into the deepest position of the internal lock cylinder 2, and the wire or the like is not beneficial to further bending and unlocking if located at the deepest position, so the illegal unlocking operation can be detected to some extent by the present embodiment.
Other steps and parameters are the same as those in the first or second embodiment.
The fourth concrete implementation mode: the difference between this embodiment mode and one of the first to third embodiment modes is: the processor further includes:
the second detection unit is used for detecting whether the absolute value of the difference between the moment t1 when the pressure sensor 8 receives the pressure and the moment t2 when the photoelectric sensor 7 detects that the optical signal disappears is smaller than a preset threshold value, and if not, sending a first signal to the third detection unit;
and the third detection unit judges whether the weight difference value between the pressure value received by the pressure sensor and the outer marble where the pressure sensor is located is greater than a preset value or not after receiving the first signal, and if so, sends out warning information.
If the pressure sensor 8 detects a pressure greater than the weight of the marble, it means that there is an additional acceleration that changes the marble from static to dynamic, i.e. that the marble is subjected to a lift. In the embodiment, whether the bullet lifting and the object insertion are carried out simultaneously is firstly detected, if not, the pressure value detected by the pressure sensor 8 is judged, and if the value obtained by subtracting the weight of the bullet 6 from the pressure value is larger than the threshold value, illegal unlocking is considered. The rest of the situation can be considered as a disturbance and not as an illegal operation.
Other steps and parameters are the same as those in one of the first to third embodiments.
The fifth concrete implementation mode: the difference between this embodiment and one of the first to fourth embodiments is: the lower part of each outer marble 6 is provided with a pressure sensor 8, the serial numbers of the N pressure sensors are respectively set as 1,2 and … … N according to the sequence from the outside to the inside of the lock hole, the processor further comprises a fourth detection unit, the fourth detection unit is used for detecting whether the sequence of the pressure signals detected by the N pressure sensors 8 is 1,2 … … N, and if not, a warning message is sent out. The indoor refers to the side of the security door close to the indoor, and the outdoor refers to the side of the security door close to the outdoor.
For example, when the key is normally inserted, the pins numbered 1,2 … … n are sequentially lifted, so that no alarm is triggered. And the lock opener is added and used, after the lock opener is inserted, the marbles are not necessarily lifted in sequence, and the lock opener can be lifted in any sequence. The same is true of using iron wires, which is not in accordance with the normal use of keys, thus triggering alarm. At the moment, the accuracy can be ensured to reach more than 99.9 percent.
Other steps and parameters are the same as in one of the first to fourth embodiments.
The sixth specific implementation mode: the difference between this embodiment and one of the first to fifth embodiments is: the anti-theft pin tumbler lock also comprises an alarm connected with the processor and used for sending out an alarm signal after receiving the alarm information.
The alarm signal may be an audible alarm signal, such as a beep; may be a light alarm signal, for example emitting a red flashing light; or the related information can be sent to the property terminal through software.
Other steps and parameters are the same as those in one of the first to fifth embodiments.
The seventh embodiment: the embodiment provides a graphene anti-theft spring lock, wherein a cylinder 10 is arranged at the top of at least one spring slot, a graphene pressure sensor 12 is arranged at the top of an inner cavity of the cylinder 10, a hole is formed in the bottom of the inner cavity of the cylinder 10, an inner spring 5 can penetrate into or be pulled out of the cylinder 10 through the hole, a piston 11 is arranged at the top end of the inner spring 5, a space between the piston 11 and the inner top of the cylinder 10 is a closed space, and a photoelectric sensor 7 is arranged at a preset position inside an inner lock cylinder 2.
Fig. 2 shows a schematic structural diagram of a graphene anti-theft pin tumbler lock, and only one pin tumbler is shown in fig. 2, it should be clear to those skilled in the art that a plurality of pin tumblers may be provided, and the connection relationship between other cylinders and pistons may also be set as such.
The sensor used in the present embodiment may be a graphene pressure sensor disclosed in CN201310124655.5, and the principle thereof is that a graphene film senses a change in air pressure and converts the change into an electrical signal by means of an electrode or the like. The graphene pressure sensor is used for replacing a common pressure sensor in the embodiment, and the graphene pressure sensor has the advantages that: 1. the problem that illegal unlocking personnel can not easily detect the pressure sensor by slowly lifting the marble can be prevented. Because the graphene sensor has very high detection precision, any slowly acting force can be accurately detected by converting the air pressure change through the piston. 2. The graphene film is protected from damage. Since graphene films are typically very thin, they are susceptible to mechanical damage if directly subjected to contact detection. And the graphene film is protected from being damaged to a certain extent by conversion into air pressure change.
The specific implementation mode is eight: the seventh embodiment is different from the seventh embodiment in that: the number of the graphene pressure sensors 12 is 1, the number of the photoelectric sensors 7 is 1, and the photoelectric sensors 7 are arranged at the deepest positions where the tail ends of the keys can be inserted;
the processor includes:
the first detection unit is used for judging whether a receiving end of the photoelectric sensor detects an optical signal within a preset time threshold value when the graphene pressure sensor receives pressure greater than the gravity of the marble, and if so, the processor sends out warning information.
The contents of this embodiment correspond to the third embodiment, and the difference is only in the selection of the pressure sensor.
Other steps and parameters are the same as those in the seventh embodiment.
The specific implementation method nine: seventh or eighth differences from the embodiments are: the processor further includes:
the second detection unit is used for detecting whether the absolute value of the difference between the time t1 when the graphene pressure sensor receives the pressure and the time t2 when the photoelectric sensor detects that the optical signal disappears is smaller than a preset threshold value, and if not, sending a first signal to the third detection unit;
and the third detection unit judges whether the weight difference value between the pressure value received by the graphene pressure sensor and the outer marble where the pressure sensor is located is larger than a preset value or not after receiving the first signal, and if so, sends out warning information.
Other steps and parameters are the same as those of the seventh or eighth embodiment.
The detailed implementation mode is ten: the present embodiment differs from one of the seventh to ninth embodiments in that: the top of each bullet groove all is provided with cylinder 10, and the top of the cylinder 10 inner chamber all is provided with graphite alkene pressure sensor 12, sets gradually N graphite alkene pressure sensor 12's serial number to 1 respectively, 2, … … N according to the indoor order of outdoor in lockhole 1, the treater still includes the fourth detecting element for whether the order that N graphite alkene pressure sensor 12 detected pressure signal is 1,2 … … N, if no, then sends warning information.
Other steps and parameters are the same as those in one of the seventh to ninth embodiments.
The present invention is capable of other embodiments and its several details are capable of modifications in various obvious respects, all without departing from the spirit and scope of the present invention.
