[0055] Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0056] The terms used in the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "the" and "the" used in the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0057] It should be understood that although the terms "first", "second", "third", etc. may be used to describe various information in the present invention, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0058] Combine the following Figures 1 to 6 The detailed scheme of the access control method and system for a hydropower station provided by the embodiments of the present invention is described.

[0059] See also Figure 1 The embodiment of the present invention provides a method for access control of a hydropower station. The method is executed by a management terminal. The management terminal is connected to access control devices deployed in multiple controlled areas in the hydropower station. The method specifically includes:

[0060] Step 110: After receiving visitor information sent by at least one access control device, obtain access permission information corresponding to the controlled area where the access control device is located; wherein the visitor information includes the identity identification, identity verification method and access time of the visitor to be inspected.

[0061] It is understandable that when the access control device detects that a visitor to be inspected enters the collection area, the visitor information of the visitor to be inspected can be collected. In this embodiment, the visitor to be inspected can be a person or a vehicle.

[0062] In some embodiments, when the visitor to be inspected is a person, the access control device can be triggered to collect visitor information by the person swiping a card, face, or fingerprint. In other embodiments, when the visitor to be inspected is a vehicle, the access control device can be triggered to collect visitor information after the vehicle enters the detection range of the access control device.

[0063] In this embodiment, since the scope of the hydropower station is relatively large, multiple controlled areas can be divided within the scope of the hydropower station, for example, the controlled areas may include the main plant, production and office control building, desulfurization electric control building, chemical water system, riverside water pump house, etc. Considering that the security supervision level of each controlled area is different, access permission information can be set for each controlled area according to the actual supervision needs of each controlled area, and the access permission information can represent the permission requirements for visitors entering and exiting the corresponding controlled area.

[0064] For example, the access permission information may include identity information, identity verification method, verification time period, etc. corresponding to each visitor allowed to enter and exit the corresponding controlled area.

[0065] Step 120: Determine whether there is an identity identifier in the access permission information, and determine whether the identity authentication method and access time are consistent with the preset authentication method and allowed access period corresponding to the identity identifier in the access permission information, to obtain a first determination result.

[0066] It can be understood that judging whether the identity identifier exists in the access permission information is mainly used to identify whether the visitor to be inspected is an authorized visitor, and judging the identity authentication method and access time of the visitor to be inspected is mainly used to identify whether the identity authentication process of the visitor to be inspected is legal, that is, whether the identity authentication is performed in accordance with the prescribed identity authentication method within the allowed access period.

[0067] Through the first judgment link, unauthorized visitors and illegally verified visitors can be accurately identified, and authorized visitors and legally verified visitors can be effectively identified.

[0068] Step 130: Determine the number of times the visitor to be checked has been verified in the current time period, and determine whether the number of times the verification is within a preset number interval corresponding to the current time period to obtain a second determination result.

[0069] It is understandable that by judging the number of times the visitor to be inspected has been verified in the current period, it is possible to identify whether the visitor to be inspected has a problem of frequent verification, thereby identifying abnormal visitors with frequent verification behavior and realizing the recognition function of verification frequency.

[0070] Step 140: If both the first judgment result and the second judgment result are yes, the access control device is controlled to be turned on.

[0071] The solution provided in this embodiment can ensure the accuracy and security of the access control link by comprehensively analyzing the judgment results of the two judgment links. Compared with the manual access control supervision method, the access control efficiency is effectively improved.

[0072] In one embodiment, the identity includes a facial image of the visitor, and determining whether the identity exists in the access permission information specifically includes:

[0073] Extracting facial feature data of the visitor's face from the visitor's face image;

[0074] Comparing the facial feature data with the inventory feature data in the facial feature library in the access permission information to obtain a first comparison result;

[0075] If the first comparison result is that the facial feature data is consistent with at least part of the inventory feature data in the face feature library, it is determined that there is an identity identifier in the access permission information; otherwise, it is determined that there is no identity identifier in the access permission information.

[0076] In this embodiment, the access control device may include a face recognition integrated machine, which can detect and track the face of the visitor to be inspected, and capture a clear face image of the visitor. In actual applications, the access control device can directly transmit data information with the management terminal via TCP or IP, and the transmitted data is encrypted to ensure the security of the data transmission process.

[0077] In some embodiments, facial image samples of authorized visitors in each controlled area may be obtained first, facial feature data in the facial image samples may be extracted, and the facial feature data may be used to model the facial image samples to generate a facial feature library.

[0078] In the subsequent identity comparison stage, the facial feature data extracted from the actual collected visitor's facial image can be used to quickly search in the facial feature library to retrieve similar facial image samples, thereby assisting in identity recognition.

[0079] In some embodiments, a blacklist database may also be configured in the access permission information. In the face comparison phase, facial feature data extracted from the visitor's face image may be compared with inventory feature data in the blacklist database. If the feature similarity reaches a preset threshold, the access control device may be controlled to issue an early warning.

[0080] In one embodiment, the identity identifier includes the visitor's vehicle image and the visitor's vehicle weight, and determining whether the identity identifier exists in the access permission information specifically includes:

[0081] Extracting the license plate information and body information of the visitor vehicle from the visitor vehicle image;

[0082] Determine vehicle attribute data of the visitor's vehicle based on the license plate information, vehicle body information, and weight of the visitor's vehicle;

[0083] Comparing the vehicle attribute data with the inventory attribute data in the access permission information to obtain a second comparison result;

[0084] If the second comparison result is that the vehicle attribute data is consistent with the inventory attribute data, it is determined that the identity identifier exists in the access permission information; otherwise, it is determined that the identity identifier does not exist in the access permission information.

[0085] In this embodiment, the visitor to be inspected may also be a vehicle, and the access control device can be used to control the vehicles entering and leaving the visitor. In practical applications, the access control device may include a vehicle identification gun and a weighbridge. The vehicle identification gun can collect the visitor's vehicle image, and the weighbridge can collect the visitor's vehicle weight. Then, based on the license plate information and vehicle body information extracted from the visitor's vehicle image, as well as the visitor's vehicle weight, the vehicle attribute data of the visitor's vehicle can be determined. After comparing the vehicle attribute data with the inventory attribute data, it can be determined whether the visitor's vehicle is an authorized vehicle. In some embodiments, the vehicle body information may include information such as vehicle type, vehicle brand, and vehicle body color.

[0086] In one embodiment, the present invention provides a method for access control of a hydropower station, which may also include:

[0087] Comparing the weight of the visitor's vehicle with a preset weight corresponding to the visitor's vehicle to obtain a third comparison result;

[0088] If the third comparison result is that the weight of the visitor's vehicle is higher than the preset weight, the access control device is controlled to issue a warning message.

[0089] It should be noted that this embodiment obtains the weight of the visitor's vehicle and compares the weight of the visitor's vehicle with the preset weight. According to the comparison result, it can automatically identify and determine whether the visitor's vehicle privately carries unapproved heavy objects into or out of the hydropower station.

[0090] In actual applications, if the weight of the visitor's vehicle is higher than the preset weight, it means that the visitor's vehicle may have privately carried unapproved heavy objects into and out of the hydropower station. At this time, the access control device will send out an early warning message, which can prompt the supervisor to further check the visitor's vehicle to prevent unapproved heavy objects from illegally entering the hydropower station, further improving the security of the access control link.

[0091] In one embodiment, the management terminal is also connected to monitoring devices deployed in multiple controlled areas in the hydropower station. The embodiment of the present invention provides a method for access control of a hydropower station, which may also include:

[0092] Receiving an access control query request; wherein the access control query request includes a query object and a query time period;

[0093] In response to the access control query request, determining the target monitoring device and the target access control device corresponding to the query object;

[0094] Obtain monitoring data collected by the target monitoring device during the query period, and obtain visitor information collected by the target access control device during the query period;

[0095] Generate access control query results based on monitoring data and visitor information.

[0096] It is understandable that the monitoring device may be a monitoring camera installed in the controlled area, through which the video images in the controlled area, namely, monitoring data, can be captured.

[0097] In this embodiment, after receiving the access control query request, the monitoring data and visitor information collected during the query period can be obtained according to the target monitoring device and target access control device corresponding to the query object, and then the access control query result can be generated.

[0098] In one embodiment, the query object includes a target controlled area to be queried;

[0099] Generate access control query results based on monitoring data and visitor information, including:

[0100] Based on the monitoring data and visitor information, determine the number of visitors in the target controlled area during the query period and the identity information of each visitor;

[0101] Generate a visitor record list based on the number of visitors in the target controlled area during the query period and the identity information of each visitor;

[0102] Use the visitor record list as the access control query result.

[0103] It is understandable that if the query object is the target controlled area, the purpose of the access control query request is to query the visitor situation in the target controlled area. This embodiment counts the number of visitors and the identity information of the visitors in the target controlled area during the query period, and feeds back the access control query result to the requester in the form of a visitor record list, so that the requester can view the access control query result more clearly and intuitively.

[0104] For example, the visitor's identity information may include the visitor's name, gender, work number, ID number, and other data that can represent the visitor's identity.

[0105] In one embodiment, the query object includes the identity of the target visitor;

[0106] Generate access control query results based on monitoring data and visitor information, including:

[0107] Based on the monitoring data and visitor information, determine the target visitor's travel area during the query period and the activity period in each travel area;

[0108] Generate a list of activity records corresponding to the target visitor based on the target visitor's travel areas and activity periods in each travel area during the query period;

[0109] Use the activity record list as the access control query result.

[0110] In this embodiment, the identity identifier can be understood as identity information that uniquely represents the identity of the visitor, for example, it can be information such as an ID number, work number, fingerprint, or facial image.

[0111] It is understandable that, when the query object includes the identity of the target visitor, the purpose of the access control query request is to query the target visitor's activities in various areas. This embodiment can obtain the target visitor's activities in various areas during the query period by counting the target visitor's travel areas during the query period and the activity period of each travel area, and feed back the access control query results to the requester in the form of an activity record list, so that the requester can view the access control query results more clearly and intuitively.

[0112] In one embodiment, the management terminal is further connected to at least one mobile positioning terminal. The embodiment of the present invention provides a method for access control of a hydropower station, which may also include:

[0113] Acquiring positioning data collected by at least one mobile positioning terminal;

[0114] Based on the positioning data, determine the activity trajectory of each mobile positioning terminal;

[0115] Determine whether the activity track of each mobile positioning terminal is abnormal, and obtain a third determination result;

[0116] If the third judgment result is that the activity track of at least one mobile positioning terminal is abnormal, at least one access control device deployed in the abnormal activity track is controlled to send out an early warning message.

[0117] In some embodiments, the staff in the hydropower station can carry one or more mobile positioning terminals, such as portable mobile positioning devices such as positioning badges and positioning helmets. By connecting the management terminal with the mobile positioning terminal, the positioning data collected by each mobile positioning terminal can be obtained, and then the activity trajectory of each mobile positioning terminal can be determined. The activity trajectory can be understood as the activity trajectory of the staff wearing the mobile positioning terminal.

[0118] Since there are important equipment in some areas of the hydropower station, the safety supervision level is high and the number of authorized personnel is small, by judging whether the activity trajectory of the mobile positioning terminal is abnormal, it can be identified whether the staff wearing the mobile positioning terminal illegally enters the unauthorized area. If the activity trajectory is detected to be abnormal, it means that the staff wearing the mobile positioning terminal illegally enters the unauthorized area. At this time, there is a security risk. At least one access control device deployed in the abnormal activity trajectory can be controlled to send out an early warning message to remind relevant supervisors to promptly check the security risk area to avoid unauthorized personnel from illegally entering and causing security problems.

[0119] In some embodiments, the management terminal can also be connected to the vital signs monitoring equipment worn by the staff, and the vital signs data and real-time location data collected by each vital signs monitoring device can be received through the management terminal. When at least one vital signs data is detected to be abnormal, the controlled area where the vital signs monitoring device with the abnormality is located is located based on the real-time location data, and then the access control equipment in the controlled area is controlled to issue an early warning message.

[0120] Through the above solution, the physical condition of each staff member can be monitored in real time. When an abnormal physical condition of a staff member is detected, the access control equipment can be promptly linked to issue an early warning prompt, thereby improving the functional completeness and security of the access control link.

[0121] In one embodiment, the management terminal is also connected to fire alarm equipment deployed in multiple controlled areas in the hydropower station. The access control method for the hydropower station provided by the embodiment of the present invention may also include:

[0122] After receiving fire alarm information from at least one fire alarm device, determining a target access control device in a controlled area where the fire alarm device is located;

[0123] Control the target access control device to open.

[0124] In this embodiment, by connecting the management terminal with the fire alarm device, after receiving the fire alarm information issued by the fire alarm device, the target access control device in the controlled area where the fire alarm device is located can be promptly controlled to open, thereby improving the escape efficiency of the staff in the controlled area when a fire hazard occurs.

[0125] In some embodiments, the fire alarm device may be a fire alarm switch. When the fire alarm switch is pressed, the fire alarm is triggered, and the generated fire alarm information will be synchronously reported to the management terminal.

[0126] In one embodiment, the management terminal is also connected to monitoring devices deployed in multiple controlled areas in the hydropower station. The access control method for the hydropower station provided by the embodiment of the present invention may also include:

[0127] Receiving a motion detection request; wherein the motion detection request includes a motion detection area and a motion detection period;

[0128] In response to the motion detection request, determining at least one target monitoring device corresponding to the motion detection area, and acquiring monitoring data collected by the at least one target monitoring device;

[0129] Based on the monitoring data, determining whether an abnormality occurs in the motion detection area within the motion detection period, and obtaining a fourth determination result;

[0130] If the fourth determination result is yes, the access control device in the motion detection area is controlled to be closed.

[0131] It is understandable that motion detection is mainly used to monitor whether an object moves within a specified range, and to determine an abnormality when an object moves.

[0132] In some embodiments, the user can select a motion detection area by checking an option box in the motion detection setting interface. After selecting the motion detection area, the area box corresponding to the motion detection area can be displayed on the interface, and the area number can be listed. Click Apply, and the motion detection function setting will take effect, that is, a motion detection request can be issued.

[0133] In practical applications, the monitoring data may be monitoring videos. Before the judgment phase, the monitoring data may be preprocessed. The preprocessing phase may eliminate false alarm data in the monitoring data, such as false alarm data caused by the shaking of branches or leaves around the monitoring device, thereby improving the accuracy of subsequent judgment phases.

[0134] Based on the same general inventive concept, the present invention also protects an access control system for a hydropower station. The access control system for a hydropower station provided by the present invention is described below. The access control system for the hydropower station described below and the access control method for the hydropower station described above can be referenced to each other.

[0135] See also Figure 2 The access control system of the hydropower station provided by the embodiment of the present invention specifically includes: a management terminal 210 and access control devices 220 deployed in multiple controlled areas in the hydropower station, and the management terminal 210 can be connected to multiple access control devices 220 respectively;

[0136] When running, the management terminal 210 can implement the access control method for the hydropower station provided in the above embodiments.

[0137] Specifically, the management terminal 210 can be used to obtain access permission information corresponding to the controlled area where the access control device is located after receiving visitor information sent by at least one access control device; wherein the visitor information includes the identity identification, identity authentication method and access time of the visitor to be inspected; determine whether there is an identity identification in the access permission information, and determine whether the identity authentication method and access time are consistent with the preset verification method and allowed access time period corresponding to the identity identification in the access permission information, and obtain a first judgment result; determine the number of times the visitor to be inspected has been verified in the current time period, and determine whether the number of times the verification is within the preset number range corresponding to the current time period, and obtain a second judgment result; if both the first judgment result and the second judgment result are yes, control the access control device 220 to open, that is, control the access control device 220 to release.

[0138] In one embodiment, the identity includes a facial image of the visitor, and the process by which the management terminal 210 determines whether the identity exists in the access permission information specifically includes:

[0139] Extracting facial feature data of the visitor's face from the visitor's face image;

[0140] Comparing the facial feature data with the inventory feature data in the facial feature library in the access permission information to obtain a first comparison result;

[0141] If the first comparison result is that the facial feature data is consistent with at least part of the inventory feature data in the face feature library, it is determined that there is an identity identifier in the access permission information; otherwise, it is determined that there is no identity identifier in the access permission information.

[0142] In one embodiment, the identity identification includes the visitor's vehicle image and the visitor's vehicle weight. The management terminal 210 determines whether there is an identity identification process in the access permission information, specifically including:

[0143] Extracting the license plate information and body information of the visitor vehicle from the visitor vehicle image;

[0144] Determine vehicle attribute data of the visitor's vehicle based on the license plate information, vehicle body information, and weight of the visitor's vehicle;

[0145] Comparing the vehicle attribute data with the inventory attribute data in the access permission information to obtain a second comparison result;

[0146] If the second comparison result is that the vehicle attribute data is consistent with the inventory attribute data, it is determined that the identity identifier exists in the access permission information; otherwise, it is determined that the identity identifier does not exist in the access permission information.

[0147] In one embodiment, the management terminal 210 may also be used for:
