Description

A lock protection system

technical field

The utility model relates to the field of locks and the field of security, in particular to a method and a device for improving the safety performance of door locks.

Background technique

Usually, any lock is equipped with a key. Some keys are used to lock and open the door, and some keys are used as a mechanical means of opening the door when the original smart lock is out of power or malfunctions. All mechanical keys must have a key hole, and the key hole is necessary for all locks with mechanical unlocking.

In fact, the keyhole is both the safe entrance and the entrance of all risks. Many door locks are illegally opened because the security level of the lock itself is not enough, and criminals can easily crack the lock through the lock hole with the help of unlocking tools. When the user considers this potential safety hazard, there is only one option usually: one is to replace a lock with a higher security level. Changing the lock will bring two types of problems: one is that the operation of changing the lock itself requires certain professional knowledge and has a certain threshold; the other is that the height of the road is one foot and the height of the magic is one foot.

Detailed ways

Embodiment 1. The principle of the lock protection system of the present utility model is shown in Figure 1, including a lock protection device and a mobile terminal. The lock protection device used to block the lock hole of the lock is installed near the lock hole of the lock. The lock protection device and the mobile terminal Through communication connection; as shown in Figure 3, the lock protection device includes a first keyhole protection module, a first communication module, a first main control module, a first drive module and a first power supply module, and the first keyhole protection module has two Two states: when the lockhole protection module is in the state of blocking the lockhole of the lock, it is called the open state; when the lockhole protection module is in the state of exposing the lockhole of the lock, it is called the closed state. open" and "closed" to describe the above two states. The first communication module communicates with the mobile terminal, and the first main control module for processing instructions of the mobile terminal and giving feedback performs message interaction with the mobile terminal via the first communication module. The instruction drives the keyhole protection module to control its closing or opening; the first power supply module is used to provide the power required for the operation of the whole device. The lock protection device also includes a first alarm detection module, the first alarm detection module is connected to the first main control module, the first alarm detection module can generate an alarm signal, and feeds back the alarm signal to the first main control module; the mobile terminal includes a second A communication module and a second main control module, the second communication module establishes a wireless communication connection with the lock protection device, and the second main control module interacts with the lock protection device to execute instructions via the second communication module. The system also includes an emergency device, and the emergency device includes a third communication module and a third main control module. The third communication module is used to establish a wireless communication connection with the lock protection device to complete the transmission of information; the third main control module can obtain the user's instruction, and execute the instruction interactively with the lock protection device through the third communication module.

When using: When the user needs to use the key to unlock the lock, because the lock hole is blocked by protection, the mobile terminal or emergency device must first be used to trigger the deprotection process operation of the lock protection device; the user initiates the deprotection process operation through the mobile terminal or emergency device, first Establish a communication connection with the first communication module of the lock protection device for message interaction. The first main control module of the lock protection device judges whether the user's identity is legal. If it is legal, the first main control module sends an instruction to drive the keyhole protection module to enter the closed state , the lock hole is exposed, and the user uses the original lock key to open the door; if it is illegal, the lock protection device is in the open state and continues to protect and cover the original lock hole; after the key is pulled out, the lock protection device returns to the state of blocking the lock hole. When the lock protection device is maliciously damaged, hit or removed by external force, the lock protection device will generate an alarm message and feed back the alarm signal to the first main control module.

Embodiment 2, the principle is shown in Figure 2, a relay device is added on the basis of Embodiment 1, a relay device is provided between the lock protection device and the mobile terminal, and the relay device includes a fourth relay communication module, a second Four IP communication modules and the fourth main control module, the relay device establishes a communication connection with the lock protection device via the fourth relay communication module, establishes a communication connection with the mobile terminal via the fourth IP communication module, and the fourth main control module The messages of the four relay communication modules and the fourth IP communication module are processed and forwarded.

When in use, a relay device is provided between the lock protection device and the mobile terminal. The mobile terminal establishes a connection with the lock protection device via the relay device and performs message interaction. The first main control module of the lock protection device judges whether the user's identity is legal. If If it is legal, the first main control module sends an instruction to drive the keyhole protection module to enter the closed state to expose the keyhole, and the user uses the original lock key to open the door; if it is illegal, the lock protection device is in the open state and continues to protect and cover the original lock keyhole. When the lock protection device is maliciously damaged, impacted or removed by external force, the lock protection device will generate an alarm message, and the alarm message will be transmitted to the IP network through the relay device. It is also possible to use the emergency device to realize the switch control of the lock protection device.

Embodiment 3, the principle is the same as that of Embodiment 2. As shown in Figure 2, when in use, a relay device is provided between the lock protection device and the mobile terminal, and the mobile terminal establishes a connection with the lock protection device via the relay device and performs message interaction. The relay device detects the legality of the user's identity. If the user's identity is legal, the fourth relay communication module notifies the lock protection device to enter the closed state, and the first main control module sends an instruction to drive the keyhole protection module to enter the closed state to expose the keyhole. The lock key opens the door; if it is illegal, the lock protection device is in the open state, and continues to protect and cover the original lock hole. When the lock protection device is maliciously damaged, impacted or removed by external force, the lock protection device will generate an alarm message, and the alarm message will be transmitted to the IP network through the relay device.
