Description

Technical Field

[0001] The invention relates to an intelligent monitoring system, in particular to an intelligent monitoring system based on FPGA technology applied in the field of image communication. Background Art

[0002] FPGA, or field programmable gate array, is a programmable semiconductor device. FPGA has been widely used in image processing and video processing due to its reconfigurability and high-speed performance. Therefore, in intelligent monitoring, using FPGA to process image and video signals is a very important step. FPGA can perform digital signal processing on images or video signals captured by the camera. For image processing, FPGA can achieve high-definition image capture, image enhancement, noise reduction and edge detection; for video processing, FPGA can achieve video encoding and decoding, subtitle addition, segmentation processing and other functions; as well as audio processing, such as noise reduction, echo cancellation, etc. Due to the high-speed performance of FPGA, image and video signals can be processed in real time, which greatly improves the efficiency of intelligent monitoring.

[0003] A smart park refers to the use of modern information technology means such as the Internet of Things, big data, and cloud computing to conduct all-round management of personnel, vehicles, assets and facilities within the park to improve the safety, convenience and comfort of the park. When the intelligent monitoring system based on FPGA technology is applied to the smart park, it is generally only used for image monitoring of the overall data of the park, and cannot effectively play an active protective role in the security management of the park, thereby reducing its monitoring effect.

[0004] In order to solve the problem of active protection of park security management and control, a certain intelligent monitoring system in the market adopts a behavior recognition design and has a certain market share.

[0005] The specification of Chinese invention patent CN117238070B discloses a method and system for resident security control based on a smart community. Based on the target verification action determined by the verification action determination operation for the user to be verified, the user to be verified is subjected to access control verification. When the user to be verified has the target verification action, the user passes the access control verification. When the user to be verified passes the access control verification based on the target verification action, the current behavior information of the user to be verified in the target smart community is collected, and the historical behavior information of the user to be verified in the target smart community is extracted. The current behavior information and the historical behavior information are matched and determined, and the behavior matching degree between the current behavior information and the historical behavior information is output. The user to be verified is subjected to security control based on the behavior matching degree. Based on the above method, the reliability of resident security control can be improved.

Through the settings of the FPGA data processing end, the monitoring end, the access control end and the maintenance end, after monitoring abnormal data, while issuing an abnormal alarm reminder, it can also automatically trigger the anti-tracking function to perform real-time analysis and positioning of abnormal behavior. , quickly lock the source of the abnormality, and effectively cooperate with the response measures generated after the alarm reminder, which can not only improve the response speed and accuracy of the intelligent monitoring system to abnormal situations, but also effectively prevent the spread and impact of abnormal behaviors, and ensure the security and stable operation of the smart park. In addition, through the linkage of the FPGA data processing end, the monitoring end and the maintenance end to the access control end, the intelligent monitoring and processing system can effectively form a comprehensive security protection system and improve its functionality. Through information sharing and collaborative work among the units within it, it can realize comprehensive monitoring and management of various security incidents in the smart park, which can further ensure the safety of individuals living alone and effectively improve the overall security and emergency response capabilities of the intelligent monitoring system.

[0041] Figure 1 - Figure 4It is shown that the output end of the FPGA processing unit is also connected to a special individual marking unit, and the output ends of the special individual marking unit are respectively connected to the monitoring data acquisition unit and the access control data acquisition unit signals.

It can also effectively promote the initiative of the security protection function of the intelligent monitoring system, realize the intelligent protection function of individual behavior, and play an intelligent and active protection role while ensuring the freedom of the special individual, thereby promoting its security protection function.

The behavior state determination unit can effectively determine the source of the exception during the anti-tracking action, which can not only assist the FPGA processing unit in determining the abnormality level and promote the effectiveness of the abnormal response measures generated by the FPGA processing unit, but also assist the FPGA processing unit in identifying the accuracy of the abnormality to avoid false alarms and misjudgments.

[0043] Figure 1 - Figure 4 It is shown that the maintenance end also includes a regional division association unit, the input end of the regional division association unit is connected to the PC end signal, the output end of the regional division association unit is respectively connected to the FPGA processing unit and the anti-tracking protection unit signal, the regional division association unit can effectively cooperate with the anti-tracking protection unit, and when the anti-tracking action is automatically triggered, the partition management of the regional division management unit can be utilized to realize the rapid action of the anti-tracking protection unit on the monitoring end of the abnormal signal position, while improving the anti-tracking response speed and ensuring the anti-tracking accuracy, it effectively reduces the resource loss caused by anti-tracking and ensures the effectiveness of monitoring other locations in the smart park.

[0044] Figure 1 - Figure 4It is shown that in the process of applying the intelligent monitoring system, individual residents in the smart park can choose whether to add their personal access control data to the intelligent monitoring system according to their own needs. After choosing to add, the access control data acquisition unit can connect to the individual access control terminal 2 of the individual resident to collect the access control warning data of the individual access control terminal 2. In addition, when the intelligent monitoring system is applied, the technician uses the PC to input basic parameter data to the monitoring management setting unit and the access control data setting unit according to the environment, monitoring requirements and security level of the smart park, so that the monitoring management setting unit and the access control data setting unit can transmit these data to the FPGA processing unit, so that the FPGA processing unit sets and processes the data, wherein the data input into the monitoring management setting unit includes but is not limited to monitoring clarity, monitoring range, monitoring data volume, noise reduction parameters, monitoring data storage settings, playback parameters and monitoring anti-tracking start settings, wherein the data input into the access control data setting unit includes but is not limited to access control opening and closing rules, access control opening permissions, access control verification rules and access control emergency rules and other related data;

[0045] In the subsequent application process, the smart park manager can use the PC to make relevant settings for the public area access control terminal, corridor access control terminal, public area monitoring terminal, corridor monitoring terminal and elevator monitoring terminal to meet the application requirements of the park itself, and the smart park manager divides the monitoring area according to the park data, and transmits the regional data to the regional division association unit through the PC. The regional division association unit transmits the monitoring area data to the FPGA processing unit, which facilitates the FPGA processing unit to transmit the storage data after the division of the area to the monitoring data storage unit through regional division, and transmits the monitoring data display of the regional division port to the monitoring data storage unit, which effectively reduces the management difficulty of the smart park, improves the classification of monitoring data, facilitates subsequent retrieval and query, improves the functionality of the intelligent monitoring system, reduces its operation difficulty and reduces its operation burden, and effectively ensures the operation stability and timeliness of response of the intelligent monitoring system;

[0046] After receiving the data transmitted by the access control data setting unit and the monitoring management setting unit, the FPGA processing unit regulates the data of the public area access control terminal and the corridor access control terminal through the access control control unit, so that it can be effectively applied to the current smart park. The FPGA processing unit also regulates the public area monitoring terminal, corridor monitoring terminal and elevator monitoring terminal through the monitoring control unit, so that it can be applied to the current smart park.

[0047] The access control data collection unit can collect data from the public area access control terminal, including the number of public access control accesses, public access control access verification data, public access control alarm data and other related data; the access control data collection unit can collect data from the corridor access control terminal, including the number of corridor access control accesses, corridor access control access verification data, corridor access control alarm data and other related data; the access control data collection unit can collect alarm data from the individual access control terminal 2; the access control data collection unit transmits the collected data to the FPGA processing unit; the FPGA processing unit can judge and process the security of the smart park according to the transmitted access control data;

[0048] The monitoring data acquisition unit can collect monitoring screen data in the public area through the public area monitoring terminal, collect monitoring screen data in the corridor through the corridor monitoring terminal, and collect monitoring screen data in the elevator through the elevator monitoring terminal. Then the monitoring data acquisition unit synchronizes the monitored data to the FPGA processing unit in real time. The FPGA processing unit can judge and process the security of the smart park based on the monitoring image data;

[0049] The FPGA processing unit judges and analyzes the received access control data. When it is judged that there is no abnormality in the access control and monitoring at this time, the data is transmitted to the monitoring data display unit and the monitoring data storage unit respectively, and the access control and monitoring data are transmitted to the PC in real time through the monitoring data display unit, and the monitoring image data is stored in the monitoring data storage unit to ensure the traceability of the monitoring data; when it is judged that the access control data is abnormal, only the public area access control terminal and the corridor access control terminal of the access control data at this time need to be judged abnormally. Then, when the FPGA processing unit judges that the access control at these two places is abnormal, the abnormal alarm unit starts the alarm at the access control terminal, and sends abnormal data to the PC. The alarm starts an effective warning effect, and by sending data to the PC, the smart park management personnel are urged to view and manage the abnormal access control terminal, and at the same time, the FPGA processing unit will start the anti-tracking protection unit, which will monitor the public area monitoring terminal, the corridor monitoring terminal and the electric control monitoring terminal in the area where the abnormal position appears through the monitoring and control unit. The control end is started to collect image data of the access control at the abnormal position, and then the monitoring data collection unit transmits the anti-tracking image data to the FPGA processing unit. The FPGA processing unit judges the source of the abnormality according to the received data, and compares and analyzes the behavior of the abnormal source through the relevant data transmitted by the behavior state determination unit. After judging that it is an erroneous operation or misjudgment, the alarm is turned off through the abnormal alarm unit, and the abnormal release data is transmitted to the PC end through the abnormal alarm unit. When it is judged that the abnormality is actively triggered by humans and is persistent or abnormal, the alarm data is continuously released through the abnormal alarm unit, which plays the role of actively reminding the source of the abnormality and the nearby personnel. In addition, the management personnel of the smart park can manually intervene in the abnormality to ensure the safety of the park. The FPGA processing unit will also send a control instruction to the access control control unit, so that the access control unit can control and lock the access control with the abnormality to avoid it being abnormally opened and causing safety hazards.

[0050] After the FPGA processing unit receives the individual access control abnormal data transmitted by the individual access control terminal 2 through the access control data acquisition unit, the FPGA processing unit transmits the abnormal data to the PC through the abnormal alarm unit, so that the smart park management personnel can check and protect the individual resident's status in time. The FPGA processing unit also directly starts the anti-tracking protection unit at the same time, so that the anti-tracking protection unit directly controls the floor location of the individual access control terminal 2 through the monitoring and control unit to produce an anti-tracking effect on the corridor monitoring terminal and the elevator monitoring terminal. The monitoring data acquisition unit gives priority to the transmission of the anti-tracking monitoring data, so that the FPGA processing unit can According to the data fed back by the monitoring, and in combination with the relevant data transmitted by the behavior status determination unit, a comparative analysis is performed on the abnormal source behavior to determine the reason for the abnormal data transmission at the individual access control terminal 2 at this time. After determining that the abnormality is lifted or the abnormality is erroneous, the alarm is lifted through the abnormal alarm unit. When the abnormality is determined to be valid, the alarm at the corridor monitoring terminal at the floor location is activated to warn the current abnormal source, and the smart park management personnel are continuously urged through the PC terminal to provide safety protection for the individual resident, thereby playing a protective role for single households, especially for women living alone in the smart park, playing an active protection role to ensure their safety.

[0051] The FPGA processing unit judges and analyzes the received monitoring data. For monitoring data without anti-tracking effect, the FPGA processing unit compares and analyzes the collected monitoring image data through the behavior judgment standard data transmitted by the behavior state judgment unit. When it is judged that abnormal trend behavior occurs, the abnormal alarm unit transmits a warning signal to the PC to remind the smart park management personnel to observe and pay attention to the abnormal behavior, so that the smart park management personnel can deal with the abnormal behavior, such as sending personnel to check and patrol, which can effectively promote the protection initiative of the intelligent monitoring system and further improve its safety protection function.

[0052] When the FPGA processing unit monitors the data transmitted by the data acquisition unit and the access control data acquisition unit, and finds abnormal data, it uses the anti-tracking function of the anti-tracking protection unit to judge the abnormal source as non-miscontrol and malicious behavior. After the alarm reminder or the smart park management personnel take abnormal protection measures to effectively prevent the persistence of the abnormality, the FPGA processing unit individually marks the data of the abnormal source, and then transmits the marked data to the special individual marking unit. After receiving the signal, the special individual marking unit transmits the marked data to the access control data acquisition unit and the monitoring data acquisition unit respectively, so that in the subsequent application process, the access control data acquisition unit and the monitoring data acquisition unit can directly display the abnormal source data after obtaining it. Then, the FPGA processing unit can control the PC end to transmit the early warning signal of the abnormal source through the abnormal alarm unit, and perform intelligent monitoring on it to avoid its continuous or repeated abnormal behavior. It can also effectively take preventive measures to improve the timeliness of emergency response, further effectively ensure the safety of the smart park, and provide effective safety protection for single-person households.

[0053] Second implementation method:

[0054] Figure 1 - Figure 7 The intelligent monitoring system based on FPGA technology is shown. The corridor access control terminal is connected to the individual unit access control control terminal 1 set in the individual household through the local area network signal. The individual unit access control control terminal 1 can control the corridor access control terminal of the building through the local area network, so as to realize the remote control function of the resident on the corridor access control terminal. The rear end of the individual unit access control control terminal 1 is fixedly installed with an extended translator 3 connected to its signal. The extended translator 3 is connected to the extended signal receiver 4 through the local area network signal. The lower end of the extended signal receiver 4 is fixedly connected to the type-c interface 41. The extended signal receiver 4 is connected to the individual access control terminal 2 through the type-c interface 41 signal. The access control data acquisition unit realizes the signal connection with the individual access control terminal 2 through the cooperation of the extended translator 3 and the extended signal receiver 4.

[0055] The extended signal receiver 4 is provided with a micro conversion chip, which can receive the alarm signal in the individual access control terminal 2. The extended translator 3 is provided with a translation processing chip, which can translate the alarm signal about the individual access control terminal 2 transmitted by the extended signal receiver 4, and transmit it to the access control data acquisition unit through the local area network. Through the cooperation of the individual unit access control control terminal 1, the extended translator 3 and the extended signal receiver 4, the data monitoring of the individual access control terminal 2 of the individual resident can be effectively realized, and the linkage between the intelligent monitoring system and the individual resident can be effectively realized. While realizing the safety protection function for the individual resident and improving their living safety, especially the safety protection function for women living alone, it can also realize the optional connection with the individual resident, and can make autonomous monitoring and protection choices according to the will of the residents to meet different needs.

[0058] Figure 5 It is shown that the input end of the signal acquisition processing unit is also connected to a privacy protection unit. The protection program of the privacy protection unit adopts a solidified design. Through the solidified design of the privacy protection unit, it is ensured that the configuration parameters and operation logic of the extended signal receiver 4 are set at the factory, and cannot be modified by the user or other unauthorized entities during subsequent use, so that it can only collect data on the warning information of the individual access control terminal 2, and cannot collect other data, such as passwords, fingerprints and other data, thereby ensuring the privacy of individual residents.

[0059] Figure 1 - Figure 7It is shown that when the access control data collection unit is used in conjunction with the individual access control terminal 2 through the expansion translator 3 and the expansion signal receiver 4, the smart park manager can install the expansion signal receiver 4 on the inside of the entrance door of the individual resident when installing the individual unit access control terminal 1, and connect it to the individual access control terminal 2 signal through the type-c interface 41. The privacy protection unit with a solidified design set in the expansion signal receiver 4 can effectively block the access control data collection unit from collecting and obtaining the data of the individual access control terminal 2, so that the access control data collection unit can only obtain the warning data of the individual access control terminal 2, avoiding the collection and acquisition of other data in the individual access control terminal 2, thereby effectively ensuring the privacy of the individual resident, and then the warning data appears on the individual access control terminal 2. After that, the warning signal collection unit in the extended signal receiver 4 is transmitted to the warning signal collection unit through the type-c interface 41, the warning signal collection unit transmits the data to the signal collection processing unit, the signal collection processing unit identifies and processes the data and then transmits it to the warning signal receiving unit in the extended translator 3 through the warning signal transmission unit and the local area network, the warning signal receiving unit transmits the received signal to the translation signal processing unit, after the translation signal processing unit translates the warning signal, it is transmitted to the access control data collection unit through the extended signal transmission unit, which can effectively realize the association between the access control data collection unit and the individual access control terminal 2, realize the safety protection function for individual residents, and further promote the functionality of the intelligent monitoring system.
