Description

An intelligent security device

technical field

The invention relates to the security field, in particular to an intelligent security device.

Background technique

Existing smart home security technology is mainly applied to door locks. For safety considerations, the relevant management departments of our country require that the home security door lock must have a mechanical lock to open the door no matter what method is used, that is, a traditional key is required to open the door.

However, the mechanical door opening methods of the existing smart home door locks are directly exposed to the mechanical lock, and then unlocked through the traditional unlocking method, which objectively only provides convenience for the user, but does not substantially improve the security of the home door lock. , It is easy for criminals to directly pick the lock or open it with a master key.

In order to solve the above problems, many home security manufacturers usually adopt the method of providing special keys. The special keys are equipped with RFID (Radio Frequency Identification, also known as radio frequency identification) passive chips, and there is a card reading module in the lock cylinder. The module detects the RFID information on the key, and the mechanical lock can only be opened after the verification is passed. However, this method has the possibility of being easy to lose, easy to copy, and easy to store and forget. Although it is different from the traditional unlocking method, if the special key falls into the hands of others, the built-in RFID authentication function of the security equipment is useless, so there are still loopholes in security; in case the main control circuit board fails, the RFID authentication function will also fail. There is also the problem of not being able to unlock the lock.

Contents of the invention

In order to solve the defects of the prior art, the present invention provides an intelligent security device with high security, and the adopted technical scheme is as follows:

An intelligent security device, including a door body, a mechanical lock and an intelligent baffle device, the mechanical lock is arranged on the door body, and the mechanical lock is covered by the intelligent baffle device, and also includes a central processing unit, a control circuit module, A lock motor and an opening control module, the central processing unit is electrically connected to the terminal input module, the control circuit module, the lock motor and the opening control module respectively; the opening control module is used to control whether the door opening mode or The opening mode of the intelligent baffle device; when it is set to the opening mode of the intelligent baffle device, the central processing unit receives the unlock control signal, and controls the power on and off through the control circuit module to realize the opening and closing of the intelligent baffle device. The device includes an electromagnet and an intelligent baffle that can pull in when powered on; when it is set to the door opening mode, the central processing unit receives the unlock control signal and controls the lock motor to unlock the mechanical lock.

In the present invention, under the control of the opening control module, you can choose to open the door body or open the smart baffle, wherein in the mode of opening the smart baffle, the mechanical lock is correspondingly equipped with an electromagnet and a smart baffle, and the smart baffle When the device is working normally, the plate is attracted by the electromagnet to block the key hole of the mechanical lock. To open the baffle, it needs to be controlled by the unlock control signal, which can effectively prevent outsiders from opening the baffle with a simple tool key to open the mechanical lock. Specifically, the central processor receives the unlocking control signal, and after the central processor processes and analyzes the signal, the control circuit module controls the power-on to realize the electromagnet attracting the smart baffle or turning off the power to open the smart baffle. This method greatly reduces the risk of opening with an additional key, greatly improves the safety performance of the security equipment, and is more intelligent.

In addition, in the present invention, the security equipment also has an emergency function, wherein when the central processing unit fails to work normally, the control circuit module will power off the electromagnet, so that the smart baffle can be opened, and the user can open the mechanical lock through the key .

Preferably, the central processing unit also includes a heartbeat sending module for sending a heartbeat pulse signal to the control circuit module, and the control circuit module performs power on and off operations on the electromagnet according to the reception of the heartbeat pulse signal, thereby controlling the smart baffle opening and closing.

In the present invention, the central processing unit mainly adopts the mode of signal transmission to control the control circuit module, preferably adopting the signal transmission mode of heartbeat pulse signal, but not limited to this one, other signal transmission modes are also covered by the present invention , mainly to enable the control circuit module to trigger actions under signal control. Specifically, under normal circumstances, the heartbeat sending module in the central processing unit will send a heartbeat pulse signal to the control circuit module continuously or for a certain period of time. The plate blocks the keyhole of the mechanical lock; if the heartbeat sending module does not send a heartbeat pulse signal to the control circuit module continuously or within a specified period of time, the control circuit module will power off the electromagnet so that the smart baffle can be opened, and the central processing Whether the heartbeat sending module of the device sends the heartbeat pulse signal is affected by the external input signal and itself.

When the security device is working normally, in order to ensure safety, when using a single mode to unlock, the single module can only be a fingerprint recognition module, and when using a mixed mode to unlock, it must include fingerprint unlocking. Among them, the RFID identification module is set on the door body. Unlike the RFID special key in the prior art, it needs to use an ID card or other ic card to identify it, but it must be combined with a fingerprint sensor module to open the smart baffle. The baffle can only be opened by opening it alone or in combination with other input modules. The advantage of this is that the fingerprint information is the unique identification information of each user, and it is basically impossible for others to copy it. In this way, you don’t have to worry about the identification information used in the RFID identification module. This unsafe situation occurs when the card or key falls into the hands of criminals.

Preferably, the unlocking control signal is also generated by the smart user terminal, the smart user terminal communicates with the background server, and the background server communicates with the central processing unit.

After receiving the command, the central processing module will send the unlock mode control module Send the command to change the unlock mode. Finally, the unlocking mode control module will store this instruction, so that the central processing unit can judge the unlocking mode currently used by the device.

Preferably, it also includes a peripheral input detection module and a communication detection module electrically connected to the central processing unit, the peripheral input detection module is used to detect whether the terminal input modules can all work normally, and the communication detection module is used to detect whether the central processing unit Whether the communication connection with the background server is normal.

Preferably, when the peripheral input detection module detects that all the terminal input modules cannot work normally, and the communication detection module also detects abnormal communication, the central processor controls the circuit module to power off the electromagnet and open the smart shutter.

In the present invention, when all the modules of the terminal input module cannot work normally at the same time, and the communication connection between the background server and the central processor is also abnormal, the central processor will collect the information feedback sent by the two detection modules, and then send the heartbeat module It will stop sending the heartbeat pulse signal to the control circuit module. At this time, the control circuit module will power off the electromagnet, so that the smart baffle is in an open state, so that the user can perform mechanical unlocking. This situation belongs to emergency measures, which reflects the high emergency performance of the security equipment of the present invention. When only one of the above two methods is abnormal, the smart baffle can also be actively opened according to human needs through the other normal mode.

Preferably, the power supply used includes mains power supply and backup battery power supply module.

When the mains detection module and the backup battery detection module detect abnormal conditions At this time, the central processing unit makes the electromagnet power off to open the smart baffle through the control circuit module.

The present invention also provides another emergency measure. When the security equipment suffers from no power supply, it is obvious that the mechanical lock becomes the only way to open the door. The power detection module can detect the power supply situation in real time and feed back to the central processing unit , and then control the opening and closing of the smart baffle.

In addition, when the mains detection module detects that the mains cannot supply power normally, the module will send a command to the central processing unit to request power from the backup battery power supply module, and the central processor will send a start command to the backup power supply module after receiving the command, to make it start powering the device.

Preferably, it also includes an infrared sensing module, a timing module, a camera module and an alarm module electrically connected to the central processing unit.

When the infrared sensing module recognizes that there is someone in the monitoring area, it sends an instruction to the timing module through the central processing unit, and the timing module starts timing. If the person leaves within the time period set by the user, the infrared sensing module recognizes the monitoring area If there is no one in the area, the timer will be reset; and if the infrared sensor module recognizes that there are people in the monitoring area within the set time, the timing module will trigger the camera to take pictures of the monitoring area, and the captured pictures will be sent to the background server. The alarm module is triggered to send alarm information to the background server, and the background server sends the alarm information to the user's smart terminal, so that the user can know the security information of the monitoring area in real time.

Preferably, it also includes a geographic location information acquisition module and an identification code module, the geographic location information acquisition module and the identification code module are both electrically connected to the central processing unit, and the unique identification code of the intelligent security device is transferred to the central processing unit Information and geographic location information are sent to the background server.
