The storage module performs video encoding and compression processing on the video data collected by the video acquisition module, and the processed data can be stored in an internal large-capacity Flash memory, or can be stored on an external USB device through a USB interface.

The alarm module can be specifically configured to include a GSM wireless communication unit, a SIM card and a GSM sending unit, which mainly perform data communication through SIMCLK and SIMDATA signal lines; the GSM wireless communication module communicates with the CPU processing module through a standard serial port.

The CPU processing module, the storage module and the alarm module in the lockset of the present invention are connected by circuit wires, all of which are built in the lockset, and are integrally designed with the lockset, so that the attack and damage to the circuit can be prevented. The lockset of the present invention is connected to the user's mobile terminal such as the user's mobile phone through a wireless network, and the storage module acquires video signals from the video acquisition module, and performs video encoding, storage and decoding playback, and the collected video data can be collected by the alarm module. sent to the user's mobile terminal.

In addition, the video acquisition module of the present invention can directly send video monitoring information to the user terminal under the user's control command, and its processing flow is that after the user terminal sends out the video monitoring command, the lock of the present invention can send the collected video signals to the CPU processing module and storage module, described CPU processing module carries out picture capture and motion detection judgment to the video signal that video acquisition module sends, if detection result is abnormal state, as dynamic change in the picture exceeds certain lower limit threshold value, then to The storage module sends out control instructions, and the storage module performs MPEG encoding processing and video storage on the signal sent by the video acquisition module.

The intelligent alarm method of lockset of the present invention, as shown in Figure 2, it comprises the steps:

First, the user identity information of the legal identity is preset by the data setting module, including fingerprint information or password information, and the fingerprint information collected or the password information set is stored in the memory that comes with the lockset;

Secondly, when an illegal user attempts to destroy the lock or try a wrong password to enter the door, the data judging module judges the unlocking information received from the data acquisition module according to the legal identity information preset by the data setting module:

If the fingerprint information is incorrect or the number of password input exceeds the preset value, the data receipt module will start to work, start video acquisition and transmit the collected data to the storage module, and the storage module will MPEG encode and decode the data and then transmit it through the I/O port To the GSM wireless communication module, and start the alarm module; if the identity verification information is correct, then open the lock normally.

The specific processing flow of the method of the present invention is as follows: firstly, the user starts the monitoring system and enters the monitoring state. At this point, legitimate users can set and store legal identity information, which includes legal information such as fingerprint information or unlock passwords. After the system starts and enters the monitoring state, it starts to perform motion detection and judgment on the pictures captured by the video acquisition module to check whether the monitoring is legal. unlock information.

If the unlocking information is illegal and the motion of the picture exceeds a certain lower limit threshold, the system judges it as a valid motion, indicating that an emergency has occurred, and immediately starts video encoding and recording, and at the same time, transmits the unlocking information to the GSM wireless communication unit, and through the GSM wireless communication unit Send emergency prompts to the user terminal.

Otherwise, if the picture motion is lower than a certain lower limit threshold, the system will judge it as an invalid motion, the system will not take any action, and continue to enter the normal monitoring state. At this time, the video acquisition module will not start video acquisition.

At the same time, the system can continue to judge whether it has received the GSM command sent by the user terminal, and if so, execute the command immediately. The GSM command is generally an adjustment command of the video acquisition module up, down, left, and right. Finally, the key scanning program of the system can monitor whether the user presses the exit key, that is, each time after the motion detection judgment and the GSM command judgment are completed, it is judged whether the user issues an instruction to exit the monitoring state. If it is "Yes", judge and exit the video recording, and stop the monitoring state. Otherwise, start to capture camera images again, perform motion detection, and continue to monitor in this cycle.

The lock device of the present invention can also use a wireless communication module supporting GSM/GRPS, or even 3G, to select and open services such as GRPS, and through the CPU data and command transmission of the CPU processing module, the real-time audio output from the video acquisition module can be further transmitted to the mobile terminal. video information.

It should be understood that the above descriptions for specific embodiments are relatively detailed, and should not be construed as limiting the scope of the patent protection of the present invention, and the scope of protection of the patent protection of the present invention should be determined by the appended claims.
