Description

Technical Field

[0001] The present invention relates to the technical field of building access control equipment, and in particular to an intelligent building access control security system. Background Art

[0002] With the progress of society and the development of economy, building access control and security systems are playing an increasingly important role in ensuring building safety. Traditional access control systems mainly rely on simple identification methods such as door cards and passwords, and are opened after successful identity verification. This access control system that verifies identities one by one has low efficiency when facing a large number of people who need to pass through large buildings, and it is easy for outsiders to follow in.

[0003] The patent document with Chinese patent application number CN109830023A discloses an intelligent building access control system, including a control terminal. The intelligent building access control system also includes a fingerprint recognition device, a householder fingerprint information database storing the householder's fingerprint information and the corresponding householder fingerprint information, a pressing force detection device arranged on the fingerprint recognition device for detecting the user's pressing force when performing fingerprint recognition, and a finger drying device arranged next to the fingerprint recognition device for drying the householder's fingers.

[0004] It can be seen that in the actual use of the prior art, when a large number of people need to pass through the access control, the efficiency of people's passage is low and it is easy for outsiders to follow in. Summary of the invention

[0005] To this end, the present invention provides an intelligent building access control security system to overcome the problems in the prior art that when a large number of people need to pass through the access control, the people's passage efficiency is low and it is easy for outsiders to follow in.

[0006] To achieve the above object, the present invention provides an intelligent building access control and security system, comprising:

[0007] An access control device, comprising a first access control device and a second access control device for switching an open or closed state of the access control device;

[0008] an identification module connected to the first access control device, configured to determine an identification mode according to the lighting environment, and to identify the person to be passed according to the received input real-time password, and the identification module is further configured to determine whether to send the release signal to the first access control device according to a determination result of whether the person to be passed is an authorized person;

[0009] a personnel detection module connected to the identification module, for detecting each accompanying person who passes through the first access control device behind the person to be passed when the number of people passing through the first access control device is greater than one, so as to determine whether the accompanying person has the right of passage; and determining whether the accompanying person has the right of passage;

[0010] An early warning module is connected to the second access control device and the personnel detection module to determine whether the access authority is valid, and to determine whether to send a closing signal to the second access control and whether to issue an early warning based on the access authority of the accompanying person. When the access authority is valid, a trust score is determined based on the historical passing frequency and passing time, and based on the trust score, it is determined whether to send a closing signal to the second access control device.

[0011] Furthermore, the identification module includes:

[0012] An environment detection unit, which is used to detect the real-time light intensity of the scene, and to determine the light environment according to the real-time light intensity, the light environment including a weak light environment, a suitable light environment and a strong light intensity environment;

[0013] A selection unit is connected to the environment detection unit and is used to select a recognition mode based on the lighting environment, wherein the recognition modes include a fingerprint recognition mode for weak lighting environment and strong lighting environment and a face recognition mode for a suitable lighting environment.

[0014] Furthermore, the identification module is further provided with a determination unit connected to the selection unit, including:

[0015] A feature information library for comparing feature information identified according to the recognition mode;

[0016] Password library, used to compare the received real-time password;

[0017] Based on the comparison result between the feature information library and the password library, it is determined whether the person to be passed is an authorized person, and according to the determination result, it is determined whether to send the release information to the first access control device.

[0018] Furthermore, the personnel detection module includes:

[0019] A signal transmitting unit for transmitting a verification wireless network that requires a network password to connect;

[0020] an identification unit connected to the signal transmitting unit and used to identify the number of people passing through the first access control device;

[0021] A detection unit is connected to the identification unit and is used to detect the accompanying persons when the number of the passing persons is greater than one, and determine whether the accompanying persons have the right of passage based on the detection result.

[0022] Furthermore, the detection unit detects whether the mobile device carried by the accompanying person is connected to the verification wireless network.

[0023] Furthermore, the early warning module includes:

[0024] an authority verification unit, used to verify the passage authority when the detection unit detects that the accompanying person has the passage authority, and determine whether the passage authority of the accompanying person is valid;

[0025] An early warning unit is connected to the authority verification unit, and is used to determine a trust score according to the historical pass frequency and real-time pass time of the accompanying person, and determine whether to send a closing message to the second access control device based on the trust score.

[0026] Furthermore, the early warning unit sends a closing signal to the second access control device and issues an early warning when the accompanying person does not have access authority or has access authority but the access authority is invalid.

[0027] Furthermore, the authority verification unit obtains the MAC address of the mobile device of each accompanying person connected to the verification wireless network, compares the obtained MAC address with a pre-stored list of MAC addresses with access authority, and determines whether the access authority of the accompanying person is valid based on the comparison result.

[0028] Furthermore, the MAC addresses in the temporary MAC list are set with an access storage time, and are automatically cleared when the storage time of the MAC addresses reaches the access storage time.

[0029] Compared with the prior art, the beneficial effect of the present invention lies in that, by adopting a double access control structure, abnormal persons are effectively prevented from entering the building. The recognition module automatically adjusts the recognition mode according to the lighting environment, and verifies the identity of the authorized person in combination with the real-time password input, thereby enhancing the accuracy of personnel identity recognition. The personnel detection module can accurately detect and verify the access rights of the accompanying persons when multiple persons pass through, which not only effectively improves the efficiency of personnel passage, but also avoids the safety hazard of abnormal persons following behind. In addition, by introducing a trust scoring mechanism in the early warning module, strict identity authentication is further performed on persons with access rights when they enter abnormally, which is conducive to eliminating potential safety hazards.

[0030] Furthermore, by selecting different recognition modes under different lighting environments, interference of insufficient or excessive light on face recognition is avoided, and the probability of recognition failure is reduced, thereby ensuring the accuracy of recognition and improving recognition efficiency. By selecting the most appropriate recognition mode to identify passing persons, unnecessary energy consumption is avoided.

[0031] Furthermore, by combining the dual authentication mechanism of personal feature information recognition and password verification, a person is judged as an authorized person only when both the feature information and the password are verified, effectively preventing the possible loopholes in a single authentication method, reducing the risk of unauthorized personnel stealing identities, and improving the security and accuracy of the access control system.

[0032] Furthermore, by accurately identifying the number of people passing through through the recognition unit, the detection unit does not check the access permission when a single person enters, and checks the access permission of accompanying persons when multiple people enter, effectively determining whether to check the access permission according to different situations, thereby improving the intelligence level of the access control system and also improving the efficiency of the system.

[0033] Furthermore, the detection unit automatically captures the MAC address and compares it, and the determination of access rights is automatically completed without human intervention, thereby achieving accurate verification of personnel access rights and improving the intelligence of the system and access efficiency.

[0034] Furthermore, through the verification of access rights and further determination of trust scores, in-depth access checks are effectively performed on passers-by to conduct accurate identity assessments, significantly improving the security of the building.

[0035] Furthermore, by comparing the MAC address of the mobile device, it is possible to accurately identify whether the access permission of each accompanying person is valid, thereby preventing them from following into the building after obtaining the verification wireless network password, thereby improving the security and accuracy of the system.

[0036] Furthermore, by distinguishing between permanent and temporary MAC addresses, the system can manage access rights for different types of personnel, ensuring convenient access for long-term authorized personnel while meeting the temporary needs of temporary visitors, effectively enhancing the intelligence of the system.

[0037] Furthermore, by setting the access storage time and automatically clearing expired MAC addresses, the system realizes the automated management of temporary access rights. By setting different access storage times according to the needs of different visitors, the system realizes the precise control of temporary access rights and ensures the convenience of visitors. After the access storage time is reached, the MAC address is automatically cleared to eliminate its access rights, which not only optimizes the utilization of system resources but also avoids the risk of abnormal intrusion.

[0046] See also Figure 1 ,like Figure 1 As shown, it is a system framework diagram of an intelligent building access control and security system according to an embodiment of the present invention;

[0047] Specifically, an embodiment of the present invention provides an intelligent building access control and security system, the system comprising:

[0048] An access control device, comprising a first access control device and a second access control device for switching an open or closed state of the access control device;

[0049] an identification module connected to the first access control device, configured to determine an identification mode according to the lighting environment, and to identify the person to be passed according to the received input real-time password, and the identification module is further configured to determine whether to send the release signal to the first access control device according to a determination result of whether the person to be passed is an authorized person;

[0050] a personnel detection module connected to the identification module, for detecting each accompanying person who passes through the first access control device behind the person to be passed when the number of people passing through the first access control device is greater than one, so as to determine whether the accompanying person has the right of passage; and determining whether the accompanying person has the right of passage;

[0051] An early warning module is connected to the second access control device and the personnel detection module to determine whether the access authority is valid, and to determine whether to send a closing signal to the second access control and whether to issue an early warning based on the access authority of the accompanying person. When the access authority is valid, a trust score is determined based on the historical passing frequency and passing time, and based on the trust score, it is determined whether to send a closing signal to the second access control device.

[0052] Specifically, the access control device can be an electromagnetic lock or an electric door latch or other device. The specific structure of the access control device is not limited here. The first access control device is in a closed state when no one passes through the access control, and the second access control device is in an open state when no one passes through the access control.

[0053] Specifically, by adopting a double access control structure, abnormal people can be effectively prevented from entering the building. The recognition module automatically adjusts the recognition mode according to the lighting environment, and verifies the identity of authorized personnel in combination with real-time password input, thereby enhancing the accuracy of personnel identity recognition. The personnel detection module can accurately detect and verify the access rights of accompanying personnel when multiple people pass through, which not only effectively improves the efficiency of personnel passage, but also avoids the safety hazards of abnormal personnel following behind. In addition, by introducing a trust scoring mechanism in the early warning module, strict identity authentication is further performed on personnel with access rights when they enter abnormally, which is conducive to eliminating potential safety hazards.

[0054] Please continue reading Figure 2 ,like Figure 2 As shown, it is a schematic diagram of the structure of the identification module according to an embodiment of the present invention;

[0055] Specifically, the identification module includes:

[0056] An environment detection unit, which is used to detect the real-time light intensity of the scene, and to determine the light environment according to the real-time light intensity, the light environment including a weak light environment, a suitable light environment and a strong light intensity environment;

[0057] A selection unit is connected to the environment detection unit and is used to select a recognition mode based on the lighting environment. The recognition mode includes a fingerprint recognition mode for weak lighting environment and strong lighting environment and a face recognition mode for a suitable lighting environment.

[0058] Specifically, the environment detection unit is preset with a minimum suitable light illumination and a maximum suitable light illumination. The lighting environment is judged according to the comparison between the real-time light illumination and the minimum suitable light illumination and the maximum suitable light illumination, including a weak light environment, a suitable light environment and a strong light intensity environment. When the real-time light illumination is less than the minimum suitable light illumination, it is judged as a weak light environment; when the real-time light illumination is greater than the maximum suitable light illumination, it is judged as a strong light environment; when the real-time light illumination is not less than the minimum suitable light illumination and not greater than the maximum suitable light illumination, it is judged as a suitable light environment.

[0059] Specifically, the environment detection unit is provided with a light sensor to measure the light intensity of the environment. In the specific implementation, the preset minimum suitable light illumination Lmin=100lx, and the maximum suitable light illumination Lmax=1000lx. When the environment detection unit detects the real-time light illumination L=50lx, L<Lmin, it is judged as a weak light environment, and the fingerprint recognition mode is started. When the environment detection unit detects the real-time light illumination L=500lx, Lmin<L<Lmax, it is judged as a suitable light environment, and the face recognition mode is started. When the environment detection unit detects the real-time light illumination L=2000lx, L>Lmax, it is judged as a strong light environment, and the fingerprint recognition mode is started.

[0060] Specifically, by selecting different recognition modes under different lighting environments, the interference of insufficient or excessive light on face recognition is avoided, and the probability of recognition failure is reduced, thereby ensuring the accuracy of recognition and improving recognition efficiency. By selecting the most appropriate recognition mode to identify passing people, unnecessary energy consumption is avoided.

[0061] Specifically, the identification module is further provided with a determination unit connected to the selection unit, including:

[0062] A feature information library for comparing feature information identified according to the recognition mode;

[0063] Password library, used to compare the received real-time password;

[0064] Based on the comparison result between the feature information library and the password library, it is determined whether the person to be passed is an authorized person, and according to the determination result, it is determined whether to send the release information to the first access control device.

[0065] Specifically, when performing face recognition, the face of the person to pass is photographed and compared with the face information of authorized persons in the face information database; when performing fingerprint recognition, the fingerprint of the person to pass is entered and compared with the fingerprint information of authorized persons in the fingerprint information database; when the identified feature information is in the corresponding feature information database and the received real-time password is the same as the password corresponding to the feature information, it is determined that the person to pass is an authorized person, and the release signal is sent to the first access control device; when the identified feature information is not in the feature information database or when the identified feature information is not in the feature information database but the received real-time password is different from the password corresponding to the feature information, it is determined that the person to pass is not an authorized person, and the release signal is not sent to the first access control device.

[0066] Specifically, by combining the dual authentication mechanism of personal feature information recognition and password verification, a person is judged as an authorized person only when both the feature information and the password are verified. This effectively prevents the possible loopholes in a single authentication method, reduces the risk of unauthorized personnel stealing identities, and improves the security and accuracy of the access control system.

[0067] Please continue reading Figure 3 ,like Figure 3 As shown, it is a structural schematic diagram of a personnel detection module according to an embodiment of the present invention;

[0068] Specifically, the personnel detection module includes:

[0069] A signal transmitting unit for transmitting a verification wireless network that requires a network password to connect;

[0070] an identification unit connected to the signal transmitting unit and used to identify the number of people passing through the first access control device;

[0071] A detection unit is connected to the identification unit and is used to detect the accompanying persons when the number of the passing persons is greater than one, and determine whether the accompanying persons have the right of passage based on the detection result.

[0072] Specifically, the signal transmitting unit transmits a verification wireless network that requires a network password to connect. Only people who know the network password can connect. The identification unit detects the number of people passing through the first access control device through an infrared sensor. When the number of people is greater than one, the detection unit starts the access permission detection for the accompanying people.

[0073] Specifically, the recognition unit accurately identifies the number of people passing through. When a single person enters, the detection unit does not check the access permission. When multiple people enter, the access permission of the accompanying persons is checked. It effectively determines whether to check the access permission according to different situations, thereby improving the intelligence level of the access control system and also improving the efficiency of the system.

[0074] Specifically, the detection unit detects whether the mobile device carried by the accompanying person is connected to the verification wireless network.

[0075] Specifically, only people with access rights know the password for connecting to the verification wireless network. After passing through the first access control device, the mobile device they carry connects to the verification wireless network. The detection unit detects the MAC address of the mobile device accompanying the person passing through and compares it with the MAC address of the mobile device connected to the verification wireless network. When the detected MAC address of the mobile device is among the MAC addresses of the mobile devices connected to the verification wireless network, it is determined that the accompanying person passing through is connected to the verification wireless network and is determined to have access rights. When the detected MAC address of the mobile device is not among the MAC addresses of the mobile devices connected to the verification wireless network, it is determined that the accompanying person passing through is not connected to the verification wireless network and is determined to have no access rights.

[0076] During the specific implementation process, three accompanying persons pass through the first access control device, namely A, B and C. The detection unit detects the MAC addresses of their mobile devices, among which A device MAC: 00: 1A: 2B: 3C: 4D: 5E, B device MAC: 11: 22: 33: 44: 55: 66, C device MAC: AA: BB: CC: DD: EE: FF, and the MAC addresses of the device list connected to the verification wireless network are 00: 1A: 2B: 3C: 4D: 5E and 11: 22: 33: 44: 55: 66, among which 00: 1A: 2B: 3C: 4D: 5E and 11: 22: 33: 44: 55: 66 are among the MAC addresses of the mobile devices connected to the verification wireless network, and AA: BB: CC: DD: EE: FF is not among the MAC addresses of the mobile devices connected to the verification wireless network. It is determined that A and B have the accompanying passage permission, and C does not have the accompanying passage permission.

[0077] Specifically, the detection unit automatically captures the MAC address and compares it, without the need for human intervention, and automatically determines the access rights, thereby achieving accurate verification of personnel access rights and improving the intelligence of the system and access efficiency.

[0078] Please continue reading Figure 4 ,like Figure 4 As shown, it is a schematic diagram of the structure of the early warning module according to an embodiment of the present invention;

[0079] Specifically, the early warning module includes:

[0080] an authority verification unit, used to verify the passage authority when the detection unit detects that the accompanying person has the passage authority, and determine whether the passage authority of the accompanying person is valid;

[0081] An early warning unit is connected to the authority verification unit, and is used to determine a trust score according to the passing frequency and real-time passing time of the accompanying passing person, and determine whether to send a closing message to the second access control device based on the trust score.

[0082] Specifically, the warning unit is preset with a time score and a standard pass frequency corresponding to the real-time pass time range, a frequency score is obtained according to the historical pass frequency of the accompanying passing personnel and the standard pass frequency, a trust score is calculated according to the time score and the frequency score, the obtained trust score is compared with a preset trust score threshold, and whether to send a closing signal to the second access control device is determined according to the comparison result, the preset trust score threshold is Q0, and the trust score Q=Ks*Qs+Kt*Qt;

[0083] Among them, Ks is the frequency weight, Qs is the frequency score, Kt is the time weight, Qt is the time score, Ks is the frequency weight, Qs is the frequency score, Kt is the time weight, Qt is the time score, Qs=100*S / S0, S is the historical peer frequency, S0 is the preset standard pass frequency, and the full score of each score is 100.

[0084] In the specific implementation process, the preset trust score threshold is Q0=80, the preset standard pass frequency is 10 times per week, the pass time range 0:00-4:00 is scored as 0, the pass time range 4:00-7:00 is scored as 50, the pass time range 7:00-14:00 is scored as 100, the pass time range 14:00-17:00 is scored as 50, the pass time range 17:00-19:00 is scored as 100, and the pass time range The score for 19:00-21:00 is 50, and the score for the pass time range 21:00-24:00 is 0, Ks=0.6, Kt=0.4, a person's historical pass frequency is 4 times a week, and the pass time is 16:00, then the frequency score Qs=100*4 / 10=40, the time score Qt=50, the trust score Q=0.6*40+0.4*50=44, Q<Q0, and the early warning unit sends a closing signal to the second access control device.

[0085] Specifically, by verifying access rights and further determining trust scores, in-depth access checks are effectively performed on passers-by to conduct accurate identity assessments, significantly improving building security.

[0086] Specifically, the early warning unit sends a closing signal to the second access control device and issues an early warning when the accompanying person does not have the access authority or has the access authority but the access authority is invalid.

[0087] Specifically, the authority verification unit obtains the MAC address of the mobile device of each accompanying person connected to the verification wireless network, compares the obtained MAC address with a pre-stored list of MAC addresses with access authority, and determines whether the access authority of the accompanying person is valid based on the comparison result.

[0088] Specifically, if the acquired MAC address is in the MAC list, it is determined that the access authority of the accompanying person is valid; if the acquired MAC address is not in the MAC list, it is determined that the access authority of the accompanying person is invalid.

[0089] During the specific implementation process, the MAC addresses of the mobile devices of the three accompanying persons A, B, and C that connected to the verification wireless network are: A device MAC: 00: 1A: 2B: 3C: 4D: 5E, B device MAC: 11: 22: 33: 44: 55: 66, C device MAC: A1: B2: C3: D4: E5: F6. The MAC addresses of the three devices are compared with the pre-stored MAC address list with access permission. It is found that only A device MAC: 00: 1A: 2B: 3C: 4D: 5E and B device MAC: 11: 22: 33: 44: 55: 66 are included in the pre-stored MAC address list with access permission. Therefore, it is determined that the access permission of A and B accompanying persons is valid, and the access permission of C accompanying person is invalid.

[0090] Specifically, by comparing the MAC addresses of mobile devices, it is possible to accurately identify whether the access permissions of each accompanying person are valid, preventing them from following into the building after obtaining the verification wireless network password, thereby improving the security and accuracy of the system.

[0091] Specifically, the MAC list includes a permanent MAC list and a temporary MAC list. The permanent MAC list stores the MAC addresses of the mobile devices of the authorized personnel, and the temporary MAC list is used to store the MAC addresses of the mobile devices of the temporary visitors.

[0092] Specifically, the MAC addresses of officially authorized entrants to the building are stored in the permanent MAC list. People who temporarily enter the building to access the building can also enter the building normally after obtaining the password to verify the wireless network by storing the MAC address of their mobile device in the temporary MAC list.

[0093] Specifically, by distinguishing between permanent and temporary MAC addresses, the system can manage the access rights of different types of personnel, ensuring convenient entry for long-term authorized personnel while meeting the temporary needs of temporary visitors, effectively enhancing the intelligence of the system.

[0094] Specifically, the MAC addresses in the temporary MAC list are set with an access storage time, and are automatically cleared when the storage time of the MAC addresses reaches the access storage time.

[0095] Specifically, the temporary MAC list is set for visitors to temporarily enter the building. In order to prevent them from entering the building at will after the visit, an access storage time is set for the temporary MAC list.

[0096] Specifically, by setting the access storage time and automatically clearing expired MAC addresses, the system realizes the automated management of temporary access rights. By setting different access storage times according to the needs of different visitors, the system realizes precise control of temporary access rights and ensures the convenience of visitors. After the access storage time is reached, the MAC address is automatically cleared to eliminate its access rights, which not only optimizes the utilization of system resources but also avoids the risk of abnormal intrusion.
