It combines modern technologies such as face recognition, access control systems and video surveillance to achieve identity authentication, recording and monitoring of construction site access personnel. The system is usually composed of hardware equipment and software platforms. Hardware equipment includes access control gates, cameras, face recognition equipment, etc. The software platform provides data management, user permission settings, remote monitoring and other functions.

[0003] In order to solve the problem of personnel management in and out of construction sites, a certain entry and exit management system in the market adopts the design of a time clock to record entry and exit information, and has a certain market share.

[0004] The specification of Chinese invention patent CN201811144017.9 discloses a construction site management system based on Internet of Things technology. The invention can assess personnel entering the construction site, locate personnel in real time, monitor the environment on the construction site in real time, record vehicles entering and leaving, manage electrical equipment, and achieve all-round monitoring of the construction site, which can effectively reduce the occurrence of accidents and respond to emergencies in a timely manner.

[0005] The existing construction site entry and exit management system is not convenient for marking people with abnormal movements during the monitoring process, and it is not convenient to record the positioning trajectory of people entering and leaving the construction site. At present, the positioning update of people entering and leaving the construction site is mostly updated through monitoring equipment recognition. However, sometimes some features of people entering and leaving the construction site will change, such as changing clothes, features being blocked by foreign objects, etc. Feature changes or obstructions can easily lead to unclear monitoring and identification of visitors, and then easily lead to the loss of the positioning trajectory of some people entering and leaving the construction site. It is not easy for the system to grasp the comprehensive movement trajectory of people entering and leaving the construction site, and it is not easy to find abnormal movement trajectories of people on the construction site, and it is inconvenient to manage people entering and leaving the construction site. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing construction site entry and exit management system is inconvenient to record the positioning trajectory of people entering and leaving the construction site, it is easy to lose some of the entry and exit positioning trajectories, and it is not easy to grasp the comprehensive movement trajectory of people entering and leaving the construction site, making it inconvenient to manage the people entering and leaving the construction site.

[0011] The feature recognition module and the sub-recognition unit both recognize the feature information of a person or vehicle based on the image, and upload the recognized feature information to the data management module; the data management module matches the feature information with the data stored in the visitor information recording unit to determine the visitor's identity information, and then the monitoring unit uploads the visitor's location information to the data management module to update the location information of the corresponding visitor;

[0012] The sub-recognition module only recognizes the real-time image information collected by the corresponding monitoring module; the feature recognition module is used to recognize the historical image information collected by all monitoring modules;

[0013] The data management module is used to store and analyze visitor location information. When the visitor location information is updated, it is determined whether there is historical location information of the visitor in the monitoring area adjacent to the location point; if not, the data management module retrieves the monitoring records of the surrounding monitoring areas and calibrates the location information of the visitor;

[0014] The visitor marking module is provided with a marking list, which stores visitor information of the marked visitors. When any monitoring unit identifies a visitor in the marking list, it tracks and collects the image information of the visitor and updates the location information of the visitor in the marking list in real time.

[0015] In the above-mentioned intelligent entry and exit management system applied to the construction site, it is convenient to identify and record visitors with abnormal movement trajectories on the construction site, and it is convenient to improve the record of visitors' movement trajectories on the construction site.

[0016] As a further improvement of the present application, the specific steps of the data management module calibrating the visitor's location information include: the data management module calls the monitoring device of the visitor location update area, uses the monitoring device to perform comprehensive feature collection on the visitor, and then updates the visitor's feature information;

[0017] Then retrieve the visitor's location and historical location information, select the monitoring area between the latest historical location and the latest location, and then accurately identify the monitoring image stored in the selected monitoring area.

[0019] As a further improvement of the present application, when a visitor stays in any monitoring area for more than a set time and the visitor information is not identified, the sub-control unit controls the monitoring to take surround shots of the visitor and perform feature recognition. If the visitor's identity information is not recognized, the visitor is marked and the identified features are stored, and the system alarms.

[0020] As another improvement of the present application, when the monitoring drone performs surround shooting of the visiting person, the collected images include: facial feature images and appearance feature images of the visiting person, and the surround shooting is reset after a set time.

[0021] As another improved supplement of the present application, when the monitoring drone performs surround shooting of the visiting vehicle, the collected images include: the license plate image of the visiting vehicle, the vehicle appearance image and the image of the cargo on the vehicle.

[0022] As another improved supplement to the present application, a permission management module is connected to the terminal server, which is used to allocate visitor permissions and access permission levels for each monitoring area.

[0030] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-4 It is shown that an intelligent access management system applied to a construction site includes a terminal server, to which a monitoring module, an alarm module, a feature recognition module, a data management module, a visitor marking module and a data storage module are connected;

[0033] The data storage module is used to record the characteristic information of visitors and the visitor location record information. Visitors include visiting persons and visiting vehicles. The characteristic information of visiting persons includes facial characteristic information, identity information and appearance characteristic information of persons. The appearance characteristic information of persons includes height characteristics, body characteristics and clothing characteristics. The characteristic information of visiting vehicles includes license plate information, vehicle type information and vehicle cargo information.

[0034] The monitoring module is connected to monitoring units matching multiple monitoring areas, and multiple monitoring devices are connected to the monitoring units; the monitoring devices include monitoring drones and fixed monitoring cameras; a visitor recording device connected to a terminal server is provided at the monitoring area for entering and exiting the construction site, and an image acquisition device and a visitor information identity acquisition device are installed on the visitor recording device. The image acquisition device is used to acquire visitor images and identify and record visitor feature information; the visitor information identity acquisition device is used to collect visitor identity information, and the identity information acquisition method includes face recognition and manual filling in records; the visitor feature information and identity information are collected and stored in the data storage module;

[0035] When visitors enter or leave the construction site, their images are collected through visitor recording equipment, and feature recognition and recording are performed. Files are created and stored based on the collected visitor feature information and identity information. When visitors are in other monitoring areas within the construction site, visitor information can be updated based on the monitoring identification information of each monitoring area.

[0036] A sub-control unit connected to the control module is provided in each of the plurality of monitoring areas, the monitoring unit is connected to the sub-control module, and the sub-control module is connected to a sub-identification unit matching the feature identification module; the monitoring unit identifies the features of the visitor in the monitoring area through the sub-identification unit;

[0037] The feature recognition module and the sub-recognition unit both recognize the feature information of a person or vehicle based on the image, and upload the recognized feature information to the data management module; the data management module matches the feature information with the data stored in the visitor information recording unit to determine the visitor's identity information, and then the monitoring unit uploads the visitor's location information to the data management module to update the location information of the corresponding visitor; when updating the location information of this solution, the location of the monitoring device that recognizes the visitor can be selected as the location information, which facilitates the rapid upload of the location information, and no longer needs to determine the visitor's accurate location based on image analysis, thereby reducing the system load; it is convenient for the rapid recording and updating of the location information of ordinary visitors;

[0038] The sub-recognition module only recognizes the real-time image information collected by the corresponding monitoring module; the feature recognition module is used to recognize the historical image information collected by all monitoring modules;

[0039] The data management module is used to store and analyze visitor location information. When the visitor location information is updated, it is determined whether there is historical location information of the visitor in the monitoring area adjacent to the location point; if not, the data management module retrieves the monitoring records of the surrounding monitoring areas and calibrates the location information of the visitor;

[0040] A marking list is set in the visitor marking module, and the marking list stores the visitor information of the marked visitors. When any monitoring unit identifies a visitor in the marking list, it tracks and collects the image information of the visitor, and updates the location information of the visitor in the marking list in real time; the visitor information in the marking list is updated in real time, and when the marked visitor information is updated, the relevant security personnel of the construction site are notified synchronously, so that the security personnel of the construction site can timely grasp the status of the marked personnel in the construction site, and can timely discover the abnormal movement of the marked personnel; temporary entrants and untrustworthy personnel of the construction site can be marked to grasp the status of these personnel in the construction site, so as to facilitate the management of personnel entering and leaving the construction site;

[0041] When the monitoring unit tracks and collects the image information of the visitor, it uses the monitoring equipment to track and shoot, including: using a fixed camera to track and shoot, using a monitoring drone to track and shoot around, so as to update the movement trajectory of the marked person in the area in real time;

[0042] Alarm devices matching the alarm module are installed in multiple monitoring areas. The alarm devices include sound and light alarms and alarm information sending devices. The alarm information sending devices are used to send alarm text messages.

[0043] The specific steps of the data management module calibrating the visitor's location information include: the data management module retrieves the monitoring equipment in the visitor's location update area, uses the monitoring equipment to collect comprehensive features of the visitor, and then updates the visitor's feature information; when the monitoring equipment collects features, a monitoring drone can be used to track and shoot the visitor around, and after the feature collection is completed, the drone is reset;

[0044] When the monitoring drone performs surround shooting of the visiting person, the collected images include: facial feature images and appearance feature images of the visiting person, and the surround shooting is reset after the set time.

[0045] When the monitoring drone takes surround shots of a visiting vehicle, the collected images include: the license plate image of the visiting vehicle, the vehicle appearance image, and the image of the cargo on board.

[0046] Then retrieve the visitor's location and historical location information, select the monitoring area between the latest historical location and the latest location, and then accurately identify the monitoring image stored in the selected monitoring area. If the visitor is identified, update the visitor's historical location information; if not, mark the visitor.

[0047] In this embodiment, when a visitor enters the construction site for the first time, the visitor's identity and feature information are collected and filed. When the visitor moves in various areas of the construction site, the feature information of each visitor in the image is monitored and filed through the monitoring device and the sub-recognition unit;

[0048] The monitoring equipment can identify visitors when they move on the construction site. After the monitoring equipment identifies the visitor, it updates the visitor's location information and compares the historical location information. If the visitor has no historical location record in the adjacent monitoring area, the monitoring equipment will collect the visitor's feature information again, retrieve the monitoring records of the adjacent area of ​​the location, and perform feature recognition on the monitoring records based on the newly collected feature information;

[0049] If a visitor is identified in the monitoring record, the historical location record of the visitor is updated. If not, it means that the visitor has moved from the monitoring blind spot to the location, and the visitor's movement trajectory is abnormal. At this time, the visitor is marked for further tracking and monitoring of the visitor;

[0050] This solution facilitates the identification and recording of visitors with abnormal movement trajectories on the construction site, facilitates the identification and monitoring of abnormal movement of visitors when they enter and exit the construction site, facilitates the improvement of the record of visitors' movement trajectories on the construction site, and reduces the occurrence of missing positioning of visitor movement trajectories.

[0051] Second implementation method:

[0052] Figure 5 It shows that when a visitor stays in any monitoring area for more than the set time and the visitor information is not identified, the sub-control unit controls the monitoring to take surround shots of the visitor and perform feature recognition. If the visitor's identity information is not recognized, the visitor will be marked and the identified features will be stored, and the system will alarm.

[0053] In this embodiment, when a visitor staying in the area is not identified, the monitoring drone is called to re-collect the visitor's characteristics. If the visitor's identity is still not identified, it means that the visitor has not been recorded. The visitor is then marked and an alarm is sounded, which facilitates the alarm when an unrecorded visitor enters the construction site.

[0054] The third implementation method:

[0055] The terminal server is connected to a rights management module, which is used to allocate visitor rights and access permission levels to each monitoring area. When a visitor who does not match the access permission level is identified in the monitoring area, the visitor is marked and the system alarms.

[0056] In this implementation mode, different permissions are set for each monitoring area. When the visitor's permission level does not match the access permission level of the monitoring area where the visitor is located, the visitor is marked and the system alarms. This facilitates the access permission management of different areas within the construction site, and when a visitor enters an unauthorized area, it can be discovered and alarmed in time.

[0057] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
