DETAILED DESCRIPTION OF THE EMBODIMENTS

[0077] In order to enable those skilled in the art to understand the present invention, a further detailed explanation of the present invention will be provided in conjunction with specific implementation methods.

[0078] The embodiment provides an anti-theft method, which is suitable for the wire lock shown in FIG. 3, a circuit is arranged, and the conductive wire 6 of this circuit is arranged on at least a part of the area of the locking section of the wire rope 2, and the wire lock is judged to be opened when the conductive wire 6 is disconnected. In this embodiment, the circuit comprises an MCU and a power supply, and the power supply is used for supplying power to the circuit and the MCU, wherein the MCU and the power supply can be installed in a hard shell on the outer shell of the lock body 1 or inside the lock body 1. The MCU has a voltage or current identification pin, and the conductive wire 6 is electrically connected to the voltage or current identification pin, and when the conductive wire 6 is disconnected, the signal identified by the identification pin can be transformed, and the signal that the conductive wire 6 is physically disconnected can be converted into an electrical signal. In this embodiment, the conductive wire 6 of the circuit is arranged on the locking section of the wire rope 2, and when the thief cuts the wire rope 2, the conductive wire 6 of the circuit will also be cut, so that the wire lock can identify the information that the wire rope 2 has been cut.

[0079] It should be noted that: the locking section of the wire rope referred to in the present invention is: the part of the wire rope between the fixed end and the lock hole, when the wire rope 2 is inserted into the lock hole normally.

[0080] In this embodiment, the conductive wire 6 is insulated from the locking section of the wire rope 2, so that The circuit of the conductive wire 6 is independent of the monitoring circuit of the wire rope 2. The insulation method may include using enameled wire for conductive wire 6 or insulation medium can be installed between the locking section of the wire rope 2 and the conductive wire 6.

[0081] According to an embodiment of the present invention, the conductive wire 6 cover the area of the locking section as much as possible, the conductive wire 6 can be arranged on the area of more than 90% of the locking section, make it difficult for the thief to cut the locking section without damaging the conductive wire 6. The conductive wire 6 is preferably arranged throughout the entire area of the locking section.

[0082] According to one embodiment of the present invention, multiple conductive wires 6 are provided on the locking section, and multiple independent circuits are simultaneously formed. The multiple conductive wires 6 are all arranged on the locking section. When any of the conductive wires 6 of the circuit is disconnected, it is judged that the wire lock is opened.

[0083] Adding multiple circuits with the same function can effectively improve overall stability. When one circuit fails, other circuits can still work normally. On the other hand, it can increase the difficulty for thieves to avoid anti-theft methods.

[0084] According to an embodiment of the present invention, the circuit is independent of the original monitoring circuit of the wire rope 2, and the circuit is a normally closed circuit. the circuit is connected to an MCU, and when the MCU identifies a change in the voltage or current signal of the circuit, it is judged that the wire lock is opened.

[0085] The wire 6 is electrically connected to the identification pin of the MCU, and when the conductive wire 6 is disconnected, the voltage or current signal on the identification pin of the MCU changes. The changes may include: increase, decrease or disappearance of voltage or current, etc.

[0086] Because the circuit in this embodiment comprises an MCU, the MCU not only has an identification function, but also has the function of writing a program, so multiple implementation methods for judging the mechanism of tag lock opening, as follows:

[0087] Method 1: When the MCU identifies that the circuit is off, it judges that the wire lock is opened.

[0088] Method 2: when the MCU identifies that the circuit is suddenly off, it is judged that the wire lock is opened, which mainly refers to excluding the situation where the current signal gradually decreases until it disconnects, because in the case of power loss, the current and voltage in the circuit are slowly reduced, and finally reach the state of open circuit, so that the judgment logic can avoid the misjudgment and false alarm caused by the battery being unused for a long time or some batteries being in an abnormal state due to power loss.

[0089] Method 3: when the MCU identifies a sudden change in the voltage or current signal of the circuit, it judges that the wire lock is opened. This judgment logic can avoid the misjudgment and false alarms caused by the battery being unused for a long time or some batteries being in an abnormal state due to power loss.

[0090] Method 4: when the MCU identifies that the current signal of the circuit suddenly becomes 0, it judges that the wire lock is opened. This judgment logic can avoid the misjudgment and false alarms caused by the battery being unused for a long time or some batteries being in an abnormal state due to power loss.

[0091] According to an embodiment of the present invention, when the MCU judges that the wire lock is opened, the MCU records the opening time. In this embodiment, when the wire lock is judged to be opened, the wire lock records the opening time. In the event of a theft, investigators can trace it back by looking at the opening time.

[0092] According to an embodiment of the present invention, the MCU is connected with a transmission module, and when the MCU judges that the wire lock is opened, the MCU sends a signal that the wire lock is opened through the transmission module. At the first moment when the conductive wire 6 is disconnected, the MCU sends the opening time to the outside through the transmission module. It can increase the timeliness of anti-theft monitoring, and also increase the way to save anti-theft data, which is convenient for real-time monitoring or post-event tracing.

[0093] When judging that the wire lock is opened, the transmission module (or called data transmission module) of the wire lock sends an alarm signal. In this embodiment, the alarm signal can be wirelessly transmitted to other devices to realize the alarm, such as being transmitted to the siren through the network to carry out a wide range of reminders, and such as being transmitted to the corresponding client through the background for targeted notification. By sending an alarm signal, on the one hand, it can prompt the carrier so that it can deal with it in time, and on the other hand, it can notify other personnel related to the goods at the first time, so that they are aware of the situation of the goods in transit.

[0094] According to an embodiment of the present invention, the wire lock is provided with a GSM module, and when the MCU judges that the wire lock is opened, the MCU realizes external wireless communication with the outside through the GSM module, and the information that the wire lock is opened is sent to other terminal devices.

[0095] According to an embodiment of the present invention, The circuit is independent of the original monitoring circuit of the wire rope 2, and the circuit is a normally closed circuit.

[0096] As shown in FIG. 5, resistor R2 represents conductive wire 6 arranged on the locking section of the wire rope 2, resistor R1 represents wire rope 2, and the power supply is used to supply power to the circuit and MCU. When wire rope 2 is inserted into the locking hole, the switch in the figure is closed and the circuit is conductive. In this embodiment, when the wire lock is locked, conductive wire 6 and wire rope 2 are both connected to their respective circuits. When either of the two circuits is off, it can be judged that the wire lock is opened, which can avoid thieves from creating the illusion of unopened by short circuiting wire rope 2.

[0097] According to an embodiment of the present invention, an anti-theft method is suitable for wire lock, arrange a conductive wire 6 on at least part of the area of the locking section of the wire rope 2, and connect the conductive wire 6 in series into the monitoring circuit of the wire lock, when the wire rope 2 of the wire lock is inserted into the lock hole, the monitoring circuit is turned on, when the conductive wire 6 is disconnected, it is judged that the wire lock is opened The method of the present embodiment can achieve anti-theft function without adding additional circuits.

[0098] In this embodiment, one end of the conductive wire 6 arranged on the locking section of the wire rope 2 is electrically connected to the power supply, the other end is electrically connected to the fixed end of the wire rope 2, and the connecting points at the both ends of the conductive wire are located inside the lock body 1, such as the conductive wire 6 can be connected to the fixed end and the power supply by welding (for example, it can be brazing). The connecting point of the power supply the in the present embodiment is the positive or negative terminal that is electrically connected to the power supply. That is, the conductive wire 6 is connected in series into the existing monitoring circuit of the wire lock, and is specifically connecting points between the fixed end of the wire lock and the power supply. Its circuit structure is shown as shown in FIG. 6, wherein resistor R2 represents the conductive wire 6, and resistor R1 represents wire rope 2, when any place of the conductive wire 6 or wire rope 2 is disconnected, can cause monitoring circuit to be off, and MCU can identify the corresponding signal state change when circuit is off, thereby judge that the wire lock is opened.

[0099] In the embodiment of the connecting the conductive wire 6 in series with the wire rope 2, the two ends of the conductive wire 6 are respectively connected to the fixed end and the power supply of the wire rope 2 by welding (for example, it can be brazing). The solution of setting up a separate circuit in the previous embodiment also applies to the implementation scheme of connecting the conductive wire 6 in series with the wire rope 2. For example, the spatial layout of conductive wire 6, the judge mechanism for opening the wire lock, and the functions of the MCU.

[0100] According to an embodiment of the present invention, the embodiment provides an anti-theft wire lock, as shown in FIG. 3-4, and the anti-theft wire lock comprises:

[0101] A lock body 1, the lock body 1 is provided with a lock hole;

[0102] A wire rope 2, one end of the wire rope 2 is connected to the lock body 1, and the other end is used to insert into the lock hole for locking;

[0103] A circuit, the conductive wire 6 of the circuit is arranged on at least part of the area of the locking section on the wire rope 2, and when the conductive wire 6 is disconnected, it is judged that the wire lock is opened. The connecting points of two ends of the conductive wire 6 are all positioned inside lock body 1.

[0104] According to an embodiment of the present invention, the circuit is independent of the original monitoring circuit of the wire lock, and the circuit is a normally closed circuit. As shown in FIG. 5, resistor R2 represents conductive wire 6 arranged on the locking section of the wire rope 2, resistor R1 represents wire rope 2, and the power supply is used to supply power to the circuit and MCU. Wherein the fixed end of the wire rope 2 is connected to the VID2 pin of the MCU, the free end of the wire rope 2 is connected to the negative pole of the power supply by inserting the lock hole, so that the monitoring circuit is turned on, one end of the conductive wire 6 is connected to the positive pole of the power supply (in some scenarios, it can also be the positive pole of the power supply, as long as the circuit that the conductive wire 6 can be connected to the MCU), and the other end is connected to the VID1 pin of the MCU (it can also be to the voltage identification pin in some scenarios, As long as the circuit that connects the conductive wire 6 to the MCU can be realized). In this embodiment, after the wire lock is locked, the conductive wire 6 and the wire rope 2 are all connected to their respective circuits, and when any one of the two circuits is open, the wire lock can be judged to be opened.

[0105] In this embodiment, the MCU is connected with a data transmission module, and when the MCU judges that the wire lock is opened, the MCU sends a signal outside, the signal may include a time signal, an alarm signal, etc.

[0106] In this embodiment, the power supply and the MCU are arranged inside the lock body 1, a PCB 5 is arranged inside the lock body 1, an MCU is arranged on the PCB 5, and two ends of the conductive wire 6 are connected into the circuit by connecting to the PCB 5.

[0107] In this embodiment, the conductive wire 6 is arranged on the entire area of the locking section of the wire rope 2.

[0108] In this embodiment, a covering layer is covered on the locking section. There are various ways to match the covering layer with the conductive wire 6. For example, if the conductive wire 6 is located outside the covering layer, the covering layer acts as an insulation layer, isolating the conductive wire 6 from the wire rope 2. In this case, the conductive wire 6 does not necessarily have to be an enameled wire; For example, the conductive wire 6 is arranged within the covering layer, closely attached to the wire rope 2, and insulated from the wire rope 2. In this case, the conductive wire 6 can be made of enameled wire; For example, when the conductive wire 6 is embedded in the cover layer, the cover layer not only isolates the contact between the conductive wire 6 and the wire rope 2, but also provides fixation for the conductive wire 6.

[0109] According to an embodiment of the present invention, the conductive wire 6 is embedded in the covering layer. By setting the covering layer, the conductive wire 6 is physically integrated with the wire rope 2, so that it is difficult for the thief to separate the conductive wire and the wire rope for separate short circuits. In this implementation, the covering layer uses insulation material. In addition to combining the wire rope 2 and the conductive wire 6 together, the wire rope 2 and the conductive wire 6 can also be wrapped in the covering layer, making it impossible to short-circuit the wire rope 2 or the conductive wire 6 through non-destructive means. The covering layer in this embodiment is formed by coating with insulating paint, or it can be formed by fitting a rubber or plastic tube onto the locking section of the wire rope 2.

[0110] Further, in this embodiment, the covering layer is opaque, and when the conductive wire 6 arranged on the locking section of the wire rope 2, the covering layer also covers the locking section. Make the conductive wire 6 and the wire rope 2 visually integrated. The thief cannot distinguish the specific position of the conductive wire 6.

[0111] According to an embodiment of the present invention, as shown in FIG. 4, a sleeve 3 is sleeved on the locking section, and the conductive wire 6 is embedded in the wall of the sleeve 3. The conductive wire 6 forms a physically identical structure with the sleeve 3. When the thief attempts to evade the monitoring circuit by short circuiting the wire rope 2, it is necessary to expose the wire rope 2 covered by the sleeve 3, It is necessary to destroy the sleeve 3 of the locking section, When the thief breaks the sleeve 3, the conductive wire 6 inside it will also be damaged, and then the opening time or alarm signal will be sent out.

[0112] According to an embodiment of the present invention, a double-layer sleeve 3 is sleeved on the locking section, and the conductive wire 6 is located between the inner and outer layers of the double-layer sleeve. Placing the conductive wire 6 between the double-layer sleeves 3 is convenient for manufacturing. During manufacturing, the conductive wire 6 is first arranged on the outside of the single-layer sleeve, and then, the outer layer material is covered onto the structure, forming a double-layer sleeve 3 with conductive wires 6 embedded in the middle layer. Alternatively, a double-layer sleeve 3 can be formed by directly nesting two sleeves, one large and one small. On the one hand, sleeve 3 can protect conductive wire 6 and prevent it from breaking too easily; On the other hand, it can prevent the thief from knowing the position of the conductive wire in the sleeve 3.

[0113] According to an embodiment of the present invention, the conductive wire 6 of the locking section is wound back and forth many times between the two ends of the locking section in the sleeve 3, and the conductive wire 6 can wrap the locking section as much as possible, so as improving the difficulty of avoiding the conductive wire 6.

[0114] According to an embodiment of the present invention, in order to further improve the circumvention difficulty of avoiding the conductive wire 6, the conductive wire 6 is in a mesh shape in the sleeve 3, and the intersections of the mesh are insulated from each other. In this embodiment, the conductive wire 6 can be an enameled wire to insulate each intersection from each other.

[0115] According to an embodiment of the present invention, arrange a conductive wire 6 on at least part of the area of the locking section of the wire rope 2, and connect the conductive wire 6 in series into the monitoring circuit of the wire lock, when the wire rope 2 of the wire lock is inserted into the lock hole, the monitoring circuit is turned on, when the conductive wire 6 is disconnected, it is judged that the wire lock is opened. In this embodiment, one end of the conductive wire 6 arranged on the locking section of the wire rope 2 is electrically connected to the power supply, the other end is electrically connected to the fixed end of the wire rope 2, and the connecting points at the both ends of the conductive wire are located inside the lock body 1, such as the conductive wire 6 can be connected to the fixed end and the power supply by welding (for example, it can be brazing). The circuit structure is shown in FIG. 6, wherein resistor R2 represents the conductive wire 6, and resistor R1 represents wire rope 2, conductive wire 6 is located between wire rope 2 and the VID pin of MCU (in some scenarios it can also be voltage identification pin, as long as conductive wire 6 can be connected into monitoring circuit), when wire rope 2 is inserted into the lock hole, wire rope 2 can electrical connection with the negative pole of power supply (in some scenarios it can also be connected with power supply negative pole or positive pole. As long as the conductive wire 6 can be connected into the monitoring circuit), when the conductive wire 6 or the wire rope 2 any place is disconnected, the MCU can identify the corresponding signal state change, thereby the wire lock is judged to be opened. In this embodiment, the MCU is also connected with a data transmission module, and when the MCU judges that the wire lock is opened, a signal can be transmitted outside, and the signal may comprises a time signal, an alarm signal, etc.
