[0059] In order to facilitate the understanding of the technical solution provided by the embodiments of the present invention, the embodiments will be described below in combination with specific scenarios.

[0060] Example 3

[0061] The embodiment of the present invention also provides a maintenance isolation and locking management system, such as Figure 4 As shown, the system 100 includes: a dedicated locking device 10, a cloud service access platform 20, an APP handheld terminal 30, an isolation and locking system intranet host 40, a maintenance isolation and locking access host 50, an intranet security access device 60, and a provincial / municipal company security management and control platform 70.

[0062] The following is a description of the functions of each component in the management system:

[0063] Special locking device

[0064] The special locking device is used to realize the locking management of the five-defense padlock on the isolation boundary equipment (for example, isolating switches, grounding switches, network / cabinet doors and other electrical primary equipment and their accessories) during maintenance. After being installed on the five-defense padlock, the unlocking hole of the five-defense padlock can be covered. Before the maintenance isolation lock is unlocked, the five-defense padlock cannot be opened by computer keys, emergency unlocking keys, or special unlocking methods.

[0065] like Figure 5 As shown, the dedicated locking device 10 of this embodiment may further include: a first detection module 11, a second detection module 12, a third detection module 13, a communication module 14, a control module 15, an input module 16, a storage module 17 and a power module 18. Among them, the control module 15 is connected to each functional module, receives information sent by each module and controls each module to work.

[0066] The first detection module 11 may be an RFID reading module, which is used to read the identity information of the existing five-protection padlock and send the identity information to the control module 15 for identification. The control module 15 determines whether the dedicated locking device 10 is locked on the corresponding five-protection padlock by comparing the acquired identity information of the five-protection padlock with the identity information pre-stored in the storage module 17.

[0067] The second detection module 12 is used to determine the state information of the second detection module 12, such as the open state and the locked state. In a preferred embodiment, the second detection module 12 can detect the unlocking state of the special locking device by setting a magnetic steel and a Hall sensor, and can also use a micro switch to detect the unlocking state of the special locking device.

[0068] The third detection module 13 detects and determines whether the dedicated locking device is in an idle state or a working state (locked on a five-protection padlock) through state sensing. For example, the third detection module 13 can be implemented by a code reading coil, and the code reading coil can detect whether the dedicated locking device is installed on a five-protection padlock.

[0069] The storage module 17 is used to store the unique identity of the dedicated locking device (including the ID identified by the system and the label identified by humans), which can distinguish it from other dedicated locking devices of the same type.

[0070] The communication module 14 is connected to the control module 15, and is used to send the information detected by the first detection module 11, the second detection module 12, and the third detection module 13 to the cloud service access platform 20 through the Internet of Things or the Internet (for example, NB-IoT, 4G, 5G, etc.) according to the control instructions of the control module 15, and can send and receive unlocking requests and responses of the dedicated locking device 10.

[0071] The input module 16 may be an unlock button, which may be triggered according to user operation. The control module 15 sends an unlock request to the cloud service access platform through the communication module 14 via the switch button trigger signal received by the input module 16 .

[0072] The power supply module 18 is connected to the control module 15 to provide working power to each module in the special locking device 10 through the control module 15; it can also be connected to the control module 15, the first detection module 11, the second detection module 12, the third detection module 13, the communication module 14, the input module 16 and the storage module 17 respectively to supply power to each module respectively.

[0073] In order to facilitate the understanding of the working principle of the special locking device, the following will describe the partial structure of the cooperation between the special locking device 10 and the five-protection padlock through a specific embodiment. Figure 6 As shown, the dedicated locking device provided in this embodiment mainly includes a locking part, an emergency unlocking part and a circuit module part.

[0074] The locking part includes a locking shaft 110, a driven gear 120, a driving gear 140, a motor 150 and a dial 130. The driving gear 140 is arranged on the motor 150, and the motor 150 has the functions of forward rotation and reverse rotation, thereby driving the driving gear 140 to rotate forward and reverse. A square groove 1101 is provided at one end of the locking shaft 110 for making way when the locking device is inserted. Figure 7 As shown, the locking shaft 110 is also provided with an elongated hole 1102 connected to the square slot 1101. When the locking shaft 110 rotates, the pin 101 on the padlock 100 is stuck in the elongated hole 1102, and the axial movement of the locking shaft 110 is limited, thereby realizing the locking control of the padlock 100 by the dedicated locking device. The driven gear 120 is arranged on the locking shaft 110. The driven gear 120 rotates to drive the locking shaft 110 to rotate; at the same time, the driven gear 120 meshes with the driving gear 140. The thumbwheel 130 is arranged at one end of the locking shaft 110 away from the square slot 1101. The rotation of the locking shaft 110 drives the thumbwheel 130 to rotate at the same part, and the thumbwheel 130 toggles the micro switch 170, thereby obtaining the unlocking state of the locking device.

[0075] The emergency unlocking part includes the locking shaft 110, the driven gear 120 and the spring 200. Specifically, the emergency key is inserted from the rubber plug hole 214, pushing the driven gear 120 to compress the spring 200 to move, so that the driven gear 120 is separated from the driving gear 140, and the emergency unlocking key is turned to the unlocking position, thereby driving the locking shaft 110 to rotate to the unlocking position, and the axial restriction of the locking shaft 110 by the pin 101 of the padlock 100 is released; the emergency key is pulled out, and the driven gear 120 moves to a position meshing with the driving gear 140 under the action of the spring 200.

[0076] The circuit module part includes a control unit, a micro switch 170, a code reading coil 180, a storage unit, a communication unit and a battery, etc. Since the corresponding functions of the circuit module part have been described in detail in the previous embodiments, they will not be repeated here.

[0077] It should be noted that the structure described in this embodiment does not constitute a limitation on the special locking device of the present invention. Those skilled in the art should understand that the technical solution provided by the present invention is also applicable to special locking devices of other different structures.

[0078] APP handheld terminal

[0079] The data sent by the dedicated locking device 10 to the cloud service access platform 20 through the communication module 14 can be pushed to the APP handheld terminal 30 by the cloud service access platform 20 via the Internet of Things or mobile Internet (for example, NB-IoT, 4G, 5G, etc.), and displayed or operated through the APP application software of the handheld terminal 30.

[0080] Personnel with viewing authority can view the real-time status of the dedicated locking device 10, such as open / locked, idle / working, locked position, lock power, abnormal lock opening alarm and other information by installing and logging into the APP handheld terminal.

[0081] Personnel with operation authority can receive the unlocking request information of the dedicated locking device pushed by the cloud service access platform 20 by installing and logging in to the APP handheld terminal, can perform the unlocking authorization operation, and return the response information of approval or rejection to the dedicated locking device.

[0082] Isolation and locking system intranet host

[0083] The intranet host 40 of the isolation and locking system is deployed in the user's internal network at the substation end, and is used to display and query the real-time status information of the special locking device received and pushed by the cloud service access platform and analyzed by the maintenance isolation and locking access host, such as open / locked, idle / working, locked position, lock power, abnormal lock opening alarm and other information.

[0084] Maintenance isolation and lock access host

[0085] The maintenance isolation and locking access host 50 is a data interaction, forwarding and analysis device deployed in the external network connection, which realizes information interaction with the cloud service access platform 20 through the Internet of Things or mobile Internet (for example, NB-IoT, 4G, 5G, etc.), and realizes information interaction with the intranet security access device 60 through Ethernet. The maintenance isolation and locking access host 50 mainly realizes the analysis of the real-time status data information of the dedicated locking device in the cloud service access platform.

[0086] Cloud service access platform

[0087] The cloud service access platform 20 is a platform for centralized storage and management of data information of maintenance special locking devices, which can be a public cloud service, a private cloud service, or a hybrid cloud service. The cloud service access platform 20 is connected to the special locking device 10, the APP handheld terminal 30, and the maintenance isolation locking access host 50 by means of the Internet of Things or mobile Internet (for example, NB-IoT, 4G, 5G, etc.);

[0088] Intranet security access equipment

[0089] The intranet security access device 60 is to meet the requirements of the power grid company for network security protection data. All information in the maintenance isolation and locking management system that interacts via the internal and external networks can be accessed through the intranet security access device. The intranet security access device is only a software / hardware device added to meet the data security protection of information interaction between the internal / external network systems of the user unit.

[0090] Provincial / Municipal Company Security Management and Control Platform

[0091] The provincial / municipal company safety management and control platform 70 is deployed in the provincial / municipal power grid dispatching monitoring center. It is a data multi-platform fusion and centralized monitoring system master station built with auxiliary equipment to realize centralized remote supervision of real-time information of station-side equipment in the jurisdiction area. The platform integrates the remote monitoring and query functions of the status information of the special locking device, and can realize the monitoring and query of real-time status information such as the opening / locking, idle / working, locking position, lock power, abnormal lock opening alarm, etc. of the special locking device. The provincial / municipal company safety management and control platform is an extension and extension of the remote supervision of the provincial / municipal company and the integration of platform data in addition to the background information monitoring of this station.

[0092] The following is a detailed description of the process steps of this embodiment based on the architecture of the above-mentioned maintenance isolation and locking management system.

[0093] 1. Normal arming operation:

[0094] There are several ways to confirm the operation on the APP handheld terminal:

[0095] Solution 1: Personnel with operation authority directly determine whether to use the current dedicated locking device to perform isolation. Figure 8 The following steps may be included:

[0096] Step S801, pressing the dedicated locking device unlocking button to request unlocking.

[0097] In this step, the operator presses the unlock button of the dedicated locking device to wake up the control module, and the control module sends the unlock request received by the unlock button to the cloud service access platform through the communication module.

[0098] Step S802: The APP handheld terminal receives the unlocking application and displays an option to agree to unlock / disagree to unlock.

[0099] In this step, the cloud service platform pushes the received unlocking request to the APP handheld terminal through the Internet of Things or mobile Internet, and displays the options of agreeing to unlock and disagreeing to unlock through the APP application software of the handheld terminal.

[0100] Step S803: Select whether to agree to unlock on the APP handheld terminal.

[0101] In this step, the operator logs in to the application software of the APP handheld terminal through a personal account. If the operator selects the "Agree" option, the dedicated locking device is opened and step S804 is executed; if the operator selects the "Disagree" option, the dedicated locking device will not be opened.

[0102] Step S804, installing the opened special locking device on the on-site five-protection padlock.

[0103] In this step, the dedicated locking device reads the RFID information of the five-proof padlock to confirm the specific location of the device. After the dedicated locking device is installed on the five-proof padlock, the RFID information of the five-proof padlock is read through the first detection module to confirm the specific location of the dedicated locking device; the second detection module detects its own open and closed lock state; and the third detection module detects and determines whether the dedicated locking device is in an idle state or a working state (locked on the device) through state perception. The control module of the dedicated locking device obtains the above information detected by the first detection module, the second detection module and the third detection module to confirm the location, open and closed lock state and working state of the dedicated locking device, and stores the above state information in the storage module.

[0104] Step S805, the locking position, locking, working and other status information of the dedicated locking device are uploaded to the cloud service access platform.

[0105] In this step, the above-mentioned status information can be sent to the cloud service access platform through the communication module by the control module of the dedicated locking device.

[0106] Solution 2: Task-based execution of isolation and lockout

[0107] like Fig. 9 As shown, the isolation lockout includes the following steps:

[0108] Step S901, isolation and locking task formulation.

[0109] Before deployment, the operator logs in to the intranet host or APP handheld terminal through a personal account, selects the dedicated locking device to be used, and the five-defense lock that needs to be isolated and locked for the device, and generates an isolation and locking task;

[0110] Step S902, take the dedicated locking device and perform unlocking operation.

[0111] In this step, the operator takes the special locking device with the corresponding number in the task and presses the unlocking button of the special locking device to apply for unlocking.

[0112] Step S903, the system determines the correctness of the dedicated locking device used.

[0113] In this step, the cloud service access platform receives the unlocking application and automatically matches it with the isolation locking task. When the matching information is correct, the system automatically sends the unlocking information to the dedicated locking device, and the dedicated locking device opens, and step S904 is executed. Otherwise, an error message is prompted on the APP handheld terminal, and the dedicated locking device is prohibited from opening.

[0114] Step S904, the operator installs the opened special locking device on the corresponding on-site five-protection padlock in the isolation locking task;

[0115] Step S905, the dedicated locking device reads the RFID information of the five-proof padlock to confirm the specific location of the device.

[0116] In this embodiment, after the dedicated locking device is installed on the five-proof padlock, the RFID information of the five-proof padlock can be read through the first detection module; the open / closed / locked state of the padlock can be detected through the second detection module; and the state perception of the third detection module can be used to detect and judge whether the dedicated locking device is in an idle state or a working state (locked on the device). The control module of the dedicated locking device obtains the above information detected by the first detection module, the second detection module and the third detection module to confirm the position, open / closed / locked state and working state of the dedicated locking device, and stores the above state information in the storage module.

[0117] Step S906, the system determines whether the dedicated locking device locks the five-protection lock correctly.

[0118] In this embodiment, the locking position, locking, working and other status information of the special locking device are sent to the cloud service access platform. The cloud service platform determines whether the five-defense lock locked by the special locking device is the five-defense lock locked by the special locking device in the task; if yes, the locking is successful; if not, the system sends an error prompt to the APP handheld terminal and sends an unlocking instruction to the special locking device. The operator reconfirms the five-defense lock corresponding to the special locking device until the five-defense lock locked by the special locking device is consistent with the one specified in the isolation task.

[0119] Normal disarming operation:

[0120] Solution 1: A person with operation authority directly determines whether to unlock the current dedicated locking device. Fig.10 As shown, the following steps may be specifically included:

[0121] Step S1001, pressing the unlock button of the dedicated locking device to apply for unlocking information;

[0122] In this embodiment, the operator can press the unlock button of the dedicated locking device to be disarmed to wake up the control module, and the control module sends the unlock request received by the unlock button to the cloud service access platform through the communication module.

[0123] Step S1002: The APP handheld terminal receives the unlocking application and displays an option to agree to unlock / disagree to unlock.

[0124] In this embodiment, the cloud service platform can push the received unlocking request to the APP handheld terminal through the Internet of Things or mobile Internet, and display the options of agreeing to unlock and disagreeing to unlock through the APP application software of the handheld terminal.

[0125] Step S1003, select whether to agree to unlock on the APP handheld terminal.

[0126] In this step, the operator logs in to the application software of the APP handheld terminal using the account and password. If the operator selects the "Agree" option, the dedicated locking device is opened and step S804 is executed; if the "Disagree" option is selected, the dedicated locking device will not be opened.

[0127] Step S1004, unlock the opened special locking device from the five-protection padlock, and send the special locking state to the cloud service access platform.

[0128] Step S1005, recovering the dedicated locking device.

[0129] Solution 2: Task-based execution of isolation lock and unlock

[0130] like Fig.11 As shown, the isolation lock unlocking may include the following steps:

[0131] Step S1101, isolation unlocking task formulation.

[0132] In this embodiment, before deployment, the operator can log in to the intranet host or APP handheld terminal through a personal account, select the dedicated locking device that needs to be unlocked, and generate an isolation unlocking task.

[0133] Step S1102, pressing the unlock button of the dedicated locking device to apply for isolation unlocking.

[0134] In this embodiment, the operator can press the unlock button of the dedicated locking device to be disarmed to wake up the control module, and the control module sends the unlock request received by the unlock button to the cloud service access platform through the communication module.

[0135] Step S1103, the system determines the correctness of unlocking the dedicated locking device.

[0136] In this embodiment, the cloud service platform determines whether the dedicated locking device applied for unlocking is the dedicated locking device that needs to be unlocked in the task. If it is, the system automatically sends an unlocking instruction, the operator recycles and stores the unlocked dedicated locking device, and sends the dedicated locking status to the cloud service access platform; if it is not, the system does not send an unlocking instruction, but sends an error prompt to the APP handheld terminal, the operator reconfirms the dedicated locking device that needs to be unlocked, and applies for unlocking until the dedicated locking device applied for unlocking is consistent with the one specified in the isolation unlocking task.

[0137] The abnormal operation involved in this embodiment is described below.

[0138] In this embodiment, when the dedicated locking device is opened without authorization, both the APP handheld terminal and the host in the intranet of the isolation locking system can receive the alarm information that the device is opened abnormally. That is, when the second detection module of the dedicated locking device detects that the device changes from the locked state to the unlocked state, it sends the unlocking state information to the control module. The control module determines that the unlocking operation is an abnormal opening without authorization, and generates an alarm information, and sends the abnormal unlocking alarm information to the cloud service access platform through the communication module. The cloud service access platform pushes the above abnormal unlocking alarm information to the APP handheld terminal and the host in the intranet of the isolation locking system.

[0139] In this embodiment, abnormal unlocking refers to the use of unauthorized emergency unlocking methods and abnormal device operation methods (such as prying, violent unlocking, etc.) when the dedicated locking device is operating normally.

[0140] The fault operation involved in this embodiment is described below.

[0141] In this embodiment, when a special locking device fails, an emergency unlocking method can be used. The emergency unlocking method in this embodiment is different from the emergency unlocking method of the five-protection lock. In this embodiment, after the special locking device is opened in an emergency manner, the APP handheld terminal and the host in the intranet of the isolation locking system can receive information that the device is abnormally opened and can issue an alarm prompt. In this embodiment, emergency unlocking refers to the method of operating the device with an authorized emergency unlocking key when a special locking device fails.

[0142] Through the above-mentioned embodiments of the present invention, for the isolation boundary equipment that has been locked with five-protection locks, true locking control is achieved during maintenance, effectively preventing unauthorized operation of the on-site five-protection locks, improving the perception ability of on-site equipment status information, and greatly improving the feasibility of remote supervision of on-site equipment.

[0143] An embodiment of the present invention further provides a storage medium, in which a computer program is stored, wherein the computer program is configured to execute the steps of any of the above method embodiments when running.

[0144] Optionally, in this embodiment, the above-mentioned storage medium may include but is not limited to: a USB flash drive, a read-only memory (ROM), a random access memory (RAM), a mobile hard disk, a magnetic disk or an optical disk, and other media that can store computer programs.
