Description

Technical Field

[0001] This application belongs to the field of substation technology, specifically relating to a substation access control method and control system. Background Technology

[0002] Substations are an important component of power supply systems. To effectively manage substations, access control systems are often installed to verify the identity of personnel passing through. Existing substations mostly use access control systems such as passwords or fingerprints, but these systems are contact-based and can easily lead to the spread of diseases. Therefore, to avoid indirect cross-contact between personnel, contactless access control systems are needed.

[0003] For example, patent document CN114360136A proposes an intelligent security access control management system for power grid operations. The system includes: a door lock, a facial recognition terminal, a monitoring module, and a management terminal. The main method includes: acquiring facial biometric data from a whitelist, a graylist, and a blacklist, and storing this data in the management terminal; the management terminal adopts different response procedures based on different matching types of visitors. This access control management system uses facial recognition to manage different visitors, making it a contactless access control system. However, the accuracy of facial recognition is not high when people are wearing masks.

[0004] For example, patent document CN112927401A proposes a substation access control management system, including a substation access control system, a substation equipment room access control system, an access control server, a substation maintenance personnel office terminal, and a smart handheld terminal with NFC function held by substation maintenance personnel. The smart handheld terminal is equipped with an access control authorization App. The substation access control system includes a substation access control device, a substation access control unit, and a substation access control NFC sensor. The substation equipment room access control system includes an equipment room access control device, an equipment room access control unit, and an equipment room access control NFC sensor. The access control authorization App is used to apply for a substation access control permission command code to open the substation access control from the substation maintenance personnel office terminal, and also to apply for a substation equipment room access control permission command code to open the substation equipment room access control from the substation maintenance personnel office terminal. This access control system uses NFC technology as the unlocking method. However, on the one hand, the recognition distance of NFC is small (less than 10cm). To ensure recognition, NFC terminals are often placed on NFC sensors, which still poses a risk of cross-contact. On the other hand, this access control system requires users to be equipped with smart handheld terminals with NFC functionality, which increases the cost. Summary of the Invention

[0005] The technical problem to be solved by this application is to provide a substation access control method and control system to address the shortcomings of existing technologies.

[0006] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows:

[0007] A substation access control method, the control method comprising:

[0008] The system responds to a mobile phone feature code sent by a detection agency; the detection agency is used to obtain the mobile phone feature code via wireless signals, and the mobile phone feature code includes at least one of three feature codes: the MAC address of the mobile phone's WLAN module, the IMSI code of the mobile phone, and the ID number of the RFID tag affixed to the mobile phone.

[0009] Determine if the detection device is at the entrance to the equipment room. If so, close the access control at the entrance to the equipment room; otherwise, continue execution.

[0010] Determine if the mobile phone's identifier is associated with any personnel information; if so, continue execution.

[0011] Obtain the access control system corresponding to this detection agency;

[0012] Determine if the person has permission to enter the corresponding access control system; if so, open the corresponding access control system.

[0013] Furthermore, the detection mechanism corresponding to the access control at the entrance of the equipment room is located next to the mobile phone storage cabinet.

[0014] Furthermore, the personnel information includes the mobile phone identifier of the personnel's mobile phone.

[0015] Furthermore, if any one of the mobile phone feature codes sent by the detection agency matches the mobile phone feature code in the personnel information, then it is determined that the mobile phone feature code is associated with the personnel information.

[0016] A substation access control system is used to execute the control method, the control system comprising a detection mechanism, an access control mechanism, and a management mechanism;

[0017] The detection mechanism is used to obtain the mobile phone feature code through wireless signals. The mobile phone feature code includes at least one of three feature codes: the MAC address of the mobile phone's WLAN module, the IMSI code of the mobile phone, and the ID number of the RFID tag affixed to the mobile phone.

[0018] The management unit is communicatively connected to the detection unit and the access control unit, and is used to respond to the mobile phone feature code sent by the detection unit, to send door opening and closing signals to the access control unit, and to store and manage personnel information;

[0019] The detection mechanism and the access control mechanism are configured in conjunction.

[0020] Furthermore, it also includes:

[0021] The detection mechanism is located in the mobile phone storage cabinet near the equipment room;

[0022] The detection mechanism is installed at the entrance of the equipment room;

[0023] The access control mechanism, located at the entrance to the equipment room, is used to open or close the entrance to the equipment room.

[0024] Furthermore, the detection mechanism includes a processing unit, and a communication unit, a radio frequency unit, a WiFi unit, and a base station unit electrically connected to the processing unit;

[0025] The processing unit is used to perform data processing;

[0026] The communication unit is used for external communication and is connected to the management organization.

[0027] The radio frequency unit is used to obtain the ID number of the RFID tag affixed to the mobile phone;

[0028] The WiFi unit is used to obtain the MAC address of the mobile phone's WLAN module;

[0029] The base station unit is used to obtain the IMSI code of the mobile phone.

[0030] Furthermore, the personnel information includes the mobile phone identifier of the personnel's mobile phone.

[0031] Furthermore, the personnel information includes the personnel's access rights to the access control system.

[0032] Furthermore, the management agency also registers personnel information and uses the detection agency to obtain the mobile phone feature code of the personnel's mobile phone, and enters the mobile phone feature code into the corresponding personnel information.

[0033] Given the current pandemic risk, substations should adopt contactless access control systems to reduce the risk of cross-infection among users. Commonly used contactless technologies in access control systems include facial recognition, voice recognition, and contactless access cards. However, voice recognition requires speaking close to the reader to ensure accuracy, and even with masks on, droplets can still be released, increasing the risk of cross-infection between different personnel. Contactless access cards require personnel to carry a physical IC card, which is inconvenient. Therefore, considering both convenience and pandemic safety, facial recognition is the preferred technology for contactless access control systems currently available.

[0034] However, most research on facial recognition is based on standard faces, that is, face studies under conditional constraints. These faces usually have visible facial features with little or no occlusion. Slightly more complex faces are limited to those with minor angular deviations, which are corrected for by simple face alignment. When the face angle is too large or there is too much occlusion, the recognition accuracy of most current facial recognition models drops significantly.

[0035] Against the backdrop of the COVID-19 pandemic, wearing masks has become the norm, with many places mandating mask-wearing when going out. This has had a significant impact on standard facial recognition applications. When wearing masks, existing facial recognition systems designed specifically for standard facial recognition scenarios have almost lost their effectiveness. Although facial recognition technology for masked faces has developed in recent years and can now meet basic recognition needs, the accuracy of facial recognition when wearing masks remains low.

[0036] Therefore, if a contactless access control system is to be used in a substation, facial recognition remains a preferred choice for those skilled in the art. Although wearing a mask may affect the accuracy of recognition under current technology, it is still possible to complete the recognition by removing the mask.

[0037] With the widespread coverage of mobile communication networks today, smartphones have become an essential tool for daily travel, driven by needs such as entertainment, mobile payments, and QR code scanning during the pandemic. Therefore, smartphones can be conveniently used as unlocking tools for access control systems. For example, patent document CN112927401A demonstrates how to use a smartphone's NFC function to open access control systems. However, on the one hand, currently only high-end smartphones on the market support NFC; on the other hand, although NFC is a contactless technology, its recognition distance is within 10cm. In daily use, to ensure fast recognition, people often hold their phones close to the NFC sensor of the access control system, thus still posing a risk of cross-contact between people and the system.

[0038] This application also uses a mobile phone as the unlocking tool for the access control system, but the principle is to analyze the feature code in the wireless signal emitted by the mobile phone, such as the MAC address in the WiFi signal and the IMSI code in the cellular network signal. Since the MAC address and IMSI code of a mobile phone are unique, and different mobile phones have different MAC addresses and IMSI codes, the mobile phone feature code can be used to associate with a unique mobile phone, and the person holding the mobile phone can be associated with the mobile phone. Finally, the access control can be opened based on the access control authority of the person holding the mobile phone.

[0039] Because mobile WiFi and cellular network signals have long transmission distances, this application can identify mobile phone signatures over long distances. Of course, to avoid interference from irrelevant signals, the identification distance for mobile phone signatures can be set to within 2 meters.

[0040] However, some mobile phones currently use random MAC addresses when connecting to Wi-Fi networks. Therefore, the detected MAC address is not the phone's inherent MAC address, making it impossible to associate the phone with a specific person using the random MAC address. Some mobile phones also use 5G communication, which makes obtaining the phone's IMSI code more difficult, resulting in IMSI code retrieval failure. To address these issues, this application also allows for attaching RFID tags to staff members' mobile phones. The RFID tag thickness can be less than 0.5mm, so attaching it to the phone will not affect the daily user experience. Furthermore, RFID technology has a long reading distance, perfectly suited for long-distance contactless identification needs.

[0041] In equipment rooms such as the main control room, relay protection room, and communication equipment room of a substation, mobile phone signal radiation may interfere with power signals. This can range from minor signal transmission errors to serious equipment malfunctions and tripping, posing a significant threat to the safe and stable operation of the power system. Therefore, substations strictly prohibit personnel from carrying mobile phones when entering these areas with concentrated precision equipment. Although some patent documents, such as CN204288388U and CN202422373U, use warnings to remind personnel to turn off their mobile phones or leave them outside the equipment room, these methods are not mandatory and have weak binding force on staff, relying on their self-discipline.

[0042] In this case, this application also applies mobile phone feature code recognition to the entrance of the equipment room. When a mobile phone feature code is recognized at the entrance of the equipment room, it means that the person who is about to enter the equipment room is carrying a mobile phone. At this time, the access control at the entrance of the equipment room will be automatically closed to prevent the person from bringing the mobile phone into the room.

[0043] The beneficial effects of this invention are as follows:

[0044] The detection mechanism of this invention can acquire the mobile phone feature codes of staff members' mobile phones. These feature codes include at least one of three types: the MAC address of the phone's WLAN module, the phone's IMSI code, and the ID number of the RFID tag affixed to the phone. Simultaneously, the personnel information stored in the management system also includes one or more of the personnel's mobile phone feature codes. Therefore, once the detection mechanism acquires the mobile phone feature code, it can associate the phone with a specific person by comparing it with the personnel information. Thus, this invention enables unlocking of access control systems via mobile phone, without requiring the user to take out the phone, perform any access control identification or unlocking actions, or remove a mask as required for facial recognition, making it convenient and quick.

[0045] This invention utilizes wireless signals to obtain mobile phone feature codes, whether it is a MAC address, IMSI code, or RFID tag ID number, all of which can be obtained from a distance. Therefore, this invention can use a mobile phone to complete a completely remote, contactless unlocking of the access control system, avoiding cross-contact between people passing through the access control system.

[0046] This invention includes a detection mechanism at the entrance of a substation. When a staff member approaches the substation entrance carrying a mobile phone, the detection mechanism can identify the phone's unique identifier from a distance without any unlocking action. The system then automatically opens the access control at the substation entrance by comparing the unique identifier with the phone's code. Additionally, this invention includes a detection mechanism at a mobile phone storage cabinet near the equipment room. When a staff member plans to enter the equipment room, they place their phone in the storage cabinet. The detection mechanism automatically identifies the new phone's unique identifier without any unlocking action. The system then automatically opens the access control at the equipment room entrance by comparing the unique identifier with the phone's code.

[0047] This invention also includes an additional detection mechanism at the entrance to the equipment room. This mechanism monitors the mobile phone's fingerprint to determine whether a staff member intending to enter the equipment room is carrying a mobile phone. If a mobile phone is found, the access control to the equipment room is closed, preventing the staff member from bringing the mobile phone into the room. Therefore, this invention, by controlling mobile phones in the equipment room, prevents communication signals from entering the equipment room, thereby ensuring the stable and reliable operation of the equipment within the equipment room.

[0048] The access control system provided by this invention can also be applied to other parts of the substation, such as office buildings. A detection mechanism and an access control mechanism can be installed in places where access control management is required. The detection mechanism and the access control mechanism are connected to the management organization and added to the management organization. Personnel permissions for the access control mechanism are set. Attached Figure Description

[0056] To better understand this application, the content of this application is further explained clearly below with reference to embodiments and accompanying drawings. However, the protection scope of this application is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without one or more of these details.

[0057] First, the terminology used in the embodiments of this application will be explained:

[0058] WLAN: Wireless Local Area Network, uses wireless channels to connect two or more devices to form a local area network instead of wired transmission media. The WiFi commonly found in mobile phones is based on WLAN technology according to the IEEE 802.11 standard.

[0059] IMSI: International Mobile Subscriber Identity (IMSI) is a unique identifier used to distinguish different users within a cellular network. Every user on a mobile network must use an IMSI to communicate with other mobile networks, and mobile phones must utilize an IMSI to connect to the mobile network's base station.

[0060] RFID: Radio Frequency Identification (RFID) is a wireless communication technology that uses radio signals to identify specific targets and read / write related data without requiring mechanical or optical contact between the identification system and the target. Depending on the frequency band, RFID can have a recognition distance of 0.1m or more, with a maximum range of 200m.

[0061] Example 1:

[0062] The purpose of this embodiment is to provide a substation access control system for use at the entrance of a substation. For example... Figure 1 As shown, the control system includes a detection mechanism 101, a management mechanism 102, and an access control mechanism 103.

[0063] The detection unit 101 is used to obtain the mobile phone identifier of the mobile phone carried by substation workers via wireless signal. The mobile phone identifier is unique; by using the identifier, the corresponding mobile phone can be identified, and the worker's identity information can be linked to the mobile phone. In this application, the mobile phone identifier includes at least one of three identifiers: the MAC address of the mobile phone's WLAN module, the IMSI code of the mobile phone, and the ID number of the RFID tag affixed to the mobile phone.

[0064] Access control mechanism 103 is installed at the entrance of the substation to open or close the entrance. Under normal circumstances, access control mechanism 103 automatically closes the entrance of the substation. When needed, under the automatic control of management mechanism 102, it opens the entrance of the substation for authorized personnel to enter, or under manual control, it opens the entrance of the substation for visitors.

[0065] The management unit 102 is communicatively connected to the detection unit 101 and the access control unit 103. It is used to respond to the mobile phone feature code sent by the detection unit 101, to send door opening and closing signals to the access control unit 103, to store and manage personnel information and mobile phone feature codes associated with personnel, to set personnel permissions for different access control units 103, and to add or delete the detection unit 101 and the access control unit 103.

[0066] The procedure for opening the access control system to enter the substation using this embodiment is as follows:

[0067] When staff members approach the substation entrance while carrying their mobile phones, detection unit 101 automatically acquires the phone's unique identifier and sends it to management unit 102. Management unit 102 compares the identifier to determine if it belongs to a specific person. If not, the door is refused entry. If it does, management unit 102 determines if the person associated with the identifier has access privileges. If not, the door is refused entry. If so, an access signal is sent to access control unit 103. Upon receiving the signal, access control unit 103 opens the substation entrance for the staff member to enter.

[0068] like Figure 2As shown, the detection mechanism 101 includes a processing unit 201, a communication unit 202, a radio frequency (RF) unit 203, a WiFi unit 204, and a base station unit 205. The communication unit 202, RF unit 203, WiFi unit 204, and base station unit 205 are all electrically connected to the processing unit 201. The processing unit 201 is used for data processing and for data communication with the management mechanism 102 via the communication unit 202. The communication unit 202 is used for external communication and is communicatively connected to the management mechanism 102. The RF unit 203 is used to obtain the ID number of the RFID tag affixed to the mobile phone; the implementation process of the RF unit 203 is existing technology and will not be described in detail here. The WiFi unit 204 is used to obtain the MAC address of the mobile phone's WLAN module; the implementation process of the WiFi unit 204 is existing technology, and details can be found in WiFi probe technology, which will not be described in detail here. The base station unit 205 is used to obtain the IMSI code of the mobile phone (the IMSI code built into the mobile phone or the IMSI code of the SIM card on the mobile phone); the implementation process of the base station unit 205 is existing technology, and you can refer to the mobile phone code detection technology for details, which will not be described in detail here.

[0069] Management unit 102 can be a computer or a server, and its internal structure diagram can be as follows: Figure 3 As shown. The management unit 102 includes a processor, memory, and a network interface connected via a system bus, wherein the processor provides computing and control capabilities. The memory includes a non-volatile storage medium and internal memory; the non-volatile storage medium stores an operating system, computer programs, and a database; the internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The network interface is used for communication with external devices via a network connection. When the computer program is executed by the processor, it is used to execute program instructions.

[0070] The management unit 102 is also used to register staff information. Specifically, the management unit 102 first enters the staff's identity information and access permissions, then uses the detection unit 101 to obtain one or more feature codes of the staff's mobile phone, or obtains one or more feature codes by operating the staff's mobile phone, and enters the obtained mobile phone feature codes into the staff's identity information.

[0071] However, when using the detection device 101 to obtain the mobile phone's unique identifier, the following situations arise: Firstly, some existing mobile phones use random MAC addresses when connecting to Wi-Fi networks, so the detected WLAN module MAC address may not be able to link to a specific person; secondly, some existing mobile phones use 5G communication, making it more difficult to obtain the phone's IMSI code in 5G mode. Therefore, to address these issues, when registering staff, depending on the specific circumstances of the staff's mobile phone, an RFID tag can be affixed to the phone. That is, if the staff's mobile phone cannot effectively obtain the WLAN module's MAC address or the phone's IMSI code, an RFID tag is affixed to ensure that the detection device 101 can obtain the mobile phone's unique identifier.

[0072] Therefore, the mobile phone feature codes obtained by the detection agency 101 may contain multiple feature codes (MAC address of the mobile phone WLAN module, IMSI code of the mobile phone, ID number of the RFID tag affixed to the mobile phone). When the management agency 102 uses the multiple mobile phone feature codes obtained to query whether there are associated personnel, if any feature code is consistent with the mobile phone feature code stored in the personnel information, it can be confirmed that the personnel are associated with the obtained mobile phone feature codes.

[0073] In one possible implementation, to avoid interference from irrelevant surrounding signals and to prevent interference with surrounding equipment, the detection mechanism 101 is housed within a metal casing, comprising the radio frequency unit 203, the WiFi unit 204, and the base station unit 205. These components are all located on the same side of the metal casing, which has an opening facing the substation entrance. The detection mechanism 101 is positioned adjacent to the substation entrance. In this configuration, when a worker carrying a mobile phone approaches the substation entrance, the detection mechanism 101 can automatically acquire the phone's identifier, facilitating automatic access control.

[0074] In another possible implementation, the detection mechanism 101 is also equipped with a directional antenna to avoid interference from surrounding irrelevant signals. The directional antenna is directed towards the entrance of the access control system. Multiple directional antennas can be connected to the radio frequency unit 203, the WiFi unit 204, and the base station unit 205 respectively, to acquire wireless signals at the substation entrance. In this case, when a staff member carrying a mobile phone walks to the substation entrance, the detection mechanism 101 can automatically acquire the mobile phone's signature code, facilitating automatic access control.

[0075] The access control system provided in this embodiment can also be applied to other parts of the substation, such as office buildings. A detection mechanism 101 and an access control mechanism 103 can be set up in places where access control management is required. The detection mechanism 101 and the access control mechanism 103 are connected to the management mechanism 102, and the detection mechanism 101 and the access control mechanism 103 are added to the management mechanism 102. Personnel permissions for the access control mechanism 103 are set.

[0076] It should be noted that each module / unit in the above-mentioned substation access control system can be implemented in whole or in part through software, hardware, or a combination thereof.

[0077] It should be noted that the management unit 102 can be a desktop computer, laptop computer, network server, embedded device, chip system, or something else. Figure 3 Equipment with a similar structure. Furthermore... Figure 3 The structural composition shown does not constitute a limitation on this terminal device, except... Figure 3 In addition to the components shown, the device may include more or fewer components than illustrated, or combine certain components, or have different component arrangements.

[0078] Example 2:

[0079] In equipment rooms such as the main control room, relay protection room, and communication equipment room of a substation, mobile phone signal radiation may interfere with power signals. This can range from minor signal transmission errors to serious equipment malfunctions and tripping, posing a significant threat to the safe and stable operation of the power system. Therefore, substations strictly prohibit personnel from bringing mobile phones into these areas with concentrated precision equipment. Currently, substation access control systems cannot detect whether personnel are carrying mobile phones when entering equipment rooms, making it easy for phones to be accidentally brought in, posing a considerable safety hazard.

[0080] like Figure 4 As shown, the purpose of this embodiment is to provide a substation access control system, which is also applied at the entrance of the substation equipment room. This embodiment also includes an access control mechanism 103 and two sets of detection mechanisms 101 near the entrance of the equipment room, which are communicatively connected to the management agency 102.

[0081] Personnel are prohibited from bringing mobile phones into the equipment room described in this application. The access control mechanism 103 at the entrance of the equipment room is used to open or close the entrance to the equipment room.

[0082] Mobile phone storage cabinets are provided near the substation equipment room for staff to store their phones before entering the equipment room. In this embodiment, one detection mechanism 101 is installed next to the mobile phone storage cabinet to continuously monitor the mobile phone identifiers of the phones inside the cabinet; another detection mechanism 101 is installed at the entrance of the equipment room to monitor the mobile phone identifiers of the phones of staff entering the equipment room.

[0083] The procedure for opening the access control system to enter the equipment room using this embodiment is as follows:

[0084] When staff place their phones in a storage locker, a detection unit 101 next to the locker detects a new phone's unique identifier and sends it to a management unit 102. The management unit 102 compares the identifier to determine if it belongs to a specific person. If not, the door is closed. If it does, the management unit 102 checks if the person has access rights. If not, the door is closed. If so, an opening signal is sent to the access control unit 103 at the equipment room entrance. Upon receiving the signal, the access control unit 103 opens the equipment room entrance. When staff approach the equipment room entrance, the detection unit 101 monitors their phone's identifier. If detected, it sends it to the management unit 102. Upon receiving the identifier, the management unit 102, without further identification, sends a closing signal to the access control unit 103, preventing staff from bringing their phones inside.

[0085] Example 3:

[0086] The purpose of this embodiment is to provide a substation access control method, which is implemented using the control system described in Embodiment 2.

[0087] like Figure 5 As shown, the method includes:

[0088] S301, responding to the mobile phone signature code sent by the detection unit 101.

[0089] The detection unit 101 continuously monitors the mobile phone's signature. When a mobile phone signature is detected, or a new mobile phone signature is detected, the acquired mobile phone signature is sent to the management unit 102. The management unit 102 automatically responds to the mobile phone signature sent by the detection unit 101.

[0090] S302. Determine whether the detection mechanism 101 is located at the entrance of the equipment room.

[0091] The management unit 102 determines the location of the detection unit 101 that sends the mobile phone feature code. If the detection unit 101 is located at the entrance of the equipment room, it means that the staff member is carrying a mobile phone. At this time, the access control mechanism at the entrance of the equipment room is closed to prevent the staff member from bringing the mobile phone into the equipment room.

[0092] If the detection unit 101 is not at the entrance of the equipment room, continue with the subsequent steps.

[0093] S303. Determine whether the mobile phone's feature code contains associated personnel information.

[0094] Management agency 102 uses the mobile phone's unique identifier to query the stored personnel information to determine if the identifier is associated with any personnel. If such information is found, the next steps are executed.

[0095] S304. Obtain the access control corresponding to the detection device 101.

[0096] The management unit 102 obtains the access control mechanism 103 set up in cooperation with the detection mechanism 101. The detection mechanism 101 located at the mobile phone storage cabinet in the equipment room corresponds to the access control mechanism 103 at the entrance of the equipment room, and the other detection mechanisms 101 correspond to the access control mechanisms 103 in the same position.

[0097] S305. Determine whether the person has permission to enter the corresponding access control system. If so, open the corresponding access control system.

[0098] The management unit 102 obtains the permission information of the personnel associated with the detection unit 101 and determines whether the personnel have the permission to enter (open) the access control unit 103 obtained in step S304. If the personnel have the permission, the corresponding access control unit 103 is opened.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of this application, as long as they do not depart from the spirit and scope of the technical solutions of this application, should be covered within the scope of the claims of this application.
