[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] Regarding the management system of substations, a number of requirements are put forward for industrial control systems, including "implementing security requirements such as identity authentication, access control, and security auditing as required by the corresponding level of general security requirements, and using dedicated equipment and software to update control equipment to avoid the presence of malicious code programs in the firmware."

[0031] Substations currently have a large inventory of legacy systems, such as Windows and VxWorks. Due to the limitations of the intranet environment, patch upgrades are difficult, presenting numerous security risks. Furthermore, it's common for manufacturers to use their own laptops, USB flash drives, and other peripherals to directly connect to substation monitoring systems for maintenance. As a result, some provincial substations have experienced operational incidents such as illegal external connections, misoperations, malicious code infections, and illegal communication alarms. For example, the State Grid Safety Supervision Department recently reported on the infection of harmful programs in the production control area of ​​the Jilin Power 500 kV Longfeng Substation and the illegal external connection incidents in the production control area of ​​the Shanxi Power 220 kV Donghu Substation. In these typical cases, the substations' deployed Type II network security monitoring devices indirectly discovered the violations, but due to established technical principles, they collected insufficient information on operational behavior, malicious code, and secondary system operation.

[0032] Therefore, it is very necessary to take targeted control measures to establish a safe operation white environment for substations, isolate, control and audit factors such as external personnel and operation and maintenance tools, and increase the security of substation systems.

[0033] In order to solve the above technical problems, according to an embodiment of the present invention, a remote monitoring device is provided. Figure 1 This is a schematic diagram of a remote monitoring device provided according to an embodiment of the present invention. Figure 1 ,like Figure 1 As shown, the device includes: a monitoring device body 1, a connecting head 2, and a connecting line 3 connected between the monitoring device body 1 and the connecting head 2, wherein the connecting head 2 includes: a connecting body 201, a fixing buckle 202, a locking buckle 203, a low-temperature hot melt adhesive 204, a connecting hole 205 and an electromagnetic ring 206; the upper end of the connecting body 201 is fixedly connected to the fixing buckle 202, and the side wall and the lower end of the connecting body 201 are respectively fixedly connected to one end of the locking buckle 203, wherein the locking buckle 203 has a tendency to move away from the connecting body 201, and the gap between the locking buckle 203 and the connecting body 201 is filled with the low-temperature hot melt adhesive 204, and a connecting hole 205 is opened on the side of the connecting body 201 close to the connecting line 3, and an electromagnetic ring 206 is fixedly connected to the opening of the connecting hole 205.

[0034] Through the above settings, the operation and maintenance equipment can be connected to the monitoring system through the connector 2, and the fixing buckle 202 can assist in fixing the position of the connector 2 in the operation and maintenance equipment. At this time, if the operation and maintenance equipment is a safety device that allows operation and maintenance operations, the operation and maintenance equipment can directly perform normal operation and maintenance operations by providing a pre-set key. If the operation and maintenance equipment is not a safety device, the operation and maintenance equipment cannot provide the key. At this time, the monitoring device body 1 starts the emergency management system, controls the connector 2 to start heating and cuts off the power supply of the electromagnetic ring 206, disconnects the connection between the connector 2 and the connecting line 3, that is, disconnects the connection between the operation and maintenance equipment and the monitoring system. At the same time, since the locking buckle 203 has a tendency to move away from the connection body 201, and the gap between the locking buckle 203 and the connection body 201 is filled with the low-temperature hot melt adhesive 204, when the connector 2 begins to heat up, the low-temperature hot melt adhesive 204 will begin to melt and release the constraint on the locking buckle 203, and the locking buckle 203 will move away from the connection body 201. That is, at this time, the locking buckle 203 around the connection body 201 will be in an outward-stretched state, so as to trap the connector 2 in the operation and maintenance equipment and prevent it from being immediately removed. After the connection between the connector 2 and the connecting line 3 is disconnected, the connector 2 will stop heating. Therefore, the low-temperature hot melt adhesive will start to solidify again, fixing the connector 2 in the operation and maintenance equipment, so as to facilitate tracking and processing of the operation and maintenance equipment. By utilizing the above-mentioned device, combined with the preset safety equipment that allows operation and maintenance operations, the purpose of actively controlling the equipment connected to the monitoring system is achieved, thereby achieving the technical effect of ensuring the safety of operation and maintenance operations, and further solving the technical problem of difficulty in isolating, controlling and auditing external operation and maintenance tools in the substation operation environment.

[0035] If the emergency management system is installed within the monitoring device body 1, the monitoring device body 1 can directly activate the emergency management system. If the emergency management system is installed outside the monitoring device body 1, the emergency management system can also be activated through a signal connection. Furthermore, when the emergency management system is activated to control the connector 2 to start heating and cut off the power supply to the electromagnetic ring 206, the emergency management system can also be controlled by the signal connection between the emergency management system and the connector 2.

[0036] It should be noted that the above-mentioned operation and maintenance equipment is only used as an example in the operation and maintenance work scenario. According to the actual equipment management and control needs, other equipment connected to the monitoring system can also be used.

[0037] Figure 2 3 is a schematic diagram of a connecting line 3 provided according to an embodiment of the present invention. Figure 2As shown, as an optional embodiment, the connecting line 3 includes: a connecting component 301, a holding component 302 and a connecting line 303, wherein the connecting component 301 is inserted into the connecting hole 205, and the end of the connecting component 301 away from the connecting hole 205 is fixedly connected to the holding component 302, and the electromagnetic ring 206 is adsorbed on the holding component 302 when powered on, and the end of the holding component 302 away from the connecting component 301 is fixedly connected to the connecting line 303, and the end of the connecting line 303 away from the holding component 302 is fixedly connected to the monitoring device body 1.

[0038] The connecting line 3 is used to connect the monitoring device body 1 and the connector 2, and after the device is connected to the connector 2, it helps the device to access the monitoring system corresponding to the monitoring device body 1. Since the electromagnetic ring 206 is adsorbed with the holding part 302 when powered on, when the device connected to the connector 2 is not a safety device that is pre-allowed to be connected, the monitoring device body 1 will start the emergency management system and cut off the power supply of the electromagnetic ring 206. At this time, there is no longer an adsorption relationship between the electromagnetic ring 206 and the holding part 302. Therefore, the connection between the connecting line 3 and the connector 2 will be directly disconnected, thereby achieving the purpose of blocking the device from accessing the monitoring system corresponding to the monitoring device body 1 to ensure the safety of the monitoring system.

[0039] Figure 3 This is a schematic diagram of a remote monitoring device provided according to an embodiment of the present invention. Figure 2 , Figure 4 is a schematic cross-sectional view of a connector 2 provided according to an embodiment of the present invention, Figure 5 This is an enlarged schematic diagram of the cross section of the connector 2 provided according to an embodiment of the present invention, wherein: Figure 5 That is Figure 3 The enlarged schematic diagram of the part indicated by A is as follows: Figure 3-5 As shown, as an optional embodiment, the connector 2 further includes: a static contact 207, a compression spring 210, a bellows sleeve 208 and a signal transmitter 209; the groove bottom plate of the connecting hole 205 is fixedly connected to the bellows sleeve 208, and the inner wall of the bellows sleeve 208 is fixedly connected to the signal transmitter 209; the static contact 207 is arranged on the inner side of the bellows sleeve 208 and is fixedly connected to the groove bottom plate of the connecting hole 205; the compression spring 210 is arranged in the bellows sleeve 208 and is sleeved on the outer side of the signal transmitter 209, and the two ends of the compression spring 210 are respectively fixedly connected to the groove bottom plate of the connecting hole 205 and the bellows sleeve 208.

[0040] On the one hand, when the device connected to the connector 2 is not a security device that is pre-approved for access, as described above, the connector 2 will be stuck inside the device. At the same time, the signal transmitter 209 fixed on the inner wall of the corrugated sleeve 208 is activated and begins to emit an alarm signal to facilitate positioning and tracking of the device and to promptly stop the illegal intrusion of the device.

[0041] On the other hand, when the alarm is lifted and connector 2 needs to be removed from the device, this is accomplished via static contact 207. Static contact 207 requires a horizontal push to activate, meaning that static contact 207 will only activate when signal transmitter 209 and the opposing surface of static contact 207 are in full contact. Contact between signal transmitter 209 and static contact 207 can be achieved via another device (for example, a device longer than connector 301 pushes bellows 208 and signal transmitter 209). Once static contact 207 is triggered, connector 2 is heated again and electromagnetic ring 206 is re-energized, causing the previously solidified low-temperature hot melt adhesive 204 to remelt, facilitating smooth removal of connector 2 from the device.

[0042] The compression spring 210 disposed within the bellows 208 can maintain the separation between the signal transmitter 209 and the static contact 207 in the absence of external forces. It should be noted that in this embodiment, the device used to push the signal transmitter 209 into contact with the static contact 207 can be a custom-made standard device. Therefore, if an intruder uses a non-standard device to push the signal transmitter 209 into contact with the static contact 207, the compression spring 210 will cause uneven force on the bellows 208 and the signal transmitter 209, causing them to tilt, making it difficult for the static contact 207 to be triggered.

[0043] Figure 6 is a schematic diagram of a filling fiber 5 provided according to an embodiment of the present invention Figure 1 , Figure 7 is a schematic diagram of a filling fiber 5 provided according to an embodiment of the present invention Figure 2 ,like Figure 6 and Figure 7 As shown, as an optional embodiment, low-temperature hot melt adhesive 204 is embedded with filling fibers 5. The filling fibers 5 are in a three-dimensional spiral shape, and adjacent filling fibers 5 overlap to form a three-dimensional spatial structure. The three-dimensional spiral filling fibers 5 within the low-temperature hot melt adhesive 204 and the three-dimensional spatial structure formed between adjacent filling fibers 5 can lock the high-viscosity low-temperature hot melt adhesive 204 when melted by heat. This ensures that the connector 2 is fixed inside the device while also preventing excessive low-temperature hot melt adhesive 204 from remaining inside the device after the connector 2 is removed, thereby avoiding affecting the subsequent normal use of the device or causing damage to the device.

[0044] As an optional embodiment, the filling fiber 5 includes a fiber body 501 having a hollow structure. This allows the low-temperature hot melt adhesive 204 to penetrate into the fiber body 501 after melting, thereby enhancing the ability of the filling fiber 5 to lock the low-temperature hot melt adhesive 204.

[0045] As an optional embodiment, the fiber body 501 is provided with capillary cracks 502, and multiple capillary cracks 502 intersect with each other. By providing the capillary cracks 502 in the fiber body 501 and intersecting the multiple capillary cracks 502, the melted low-temperature hot melt adhesive 204 can be facilitated to penetrate the fiber body 501, thereby enhancing the effectiveness of the filling fiber 5 in locking the low-temperature hot melt adhesive 204.

[0046] Figure 8 Schematic diagram of the plastic sleeve 4 provided according to an embodiment of the present invention, Figure 8 As shown, as an optional embodiment, the above-mentioned device also includes: a plastic sleeve 4, wherein the plastic sleeve 4 is arranged on the outside of the connector 2, and the plastic sleeve 4 includes: a plastic sheet 401, so that the low-temperature hot melt adhesive 204 is not easy to form excessive residue inside the connected device.

[0047] As an optional embodiment, micropores 402 are bored in the plastic sheet 401, and the micropores 402 are evenly distributed on the surface of the plastic sheet 401. By drilling the micropores 402 in the plastic sheet 401, a small amount of low-temperature hot melt adhesive 204 can come into contact with the interior of the device after melting, achieving a fixing effect after solidification. During the removal of the connector 2, even if a small amount of low-temperature hot melt adhesive 204 remains in the device, it is easy to clean and unlikely to affect the normal use of the device. The size of the micropores 402 and their arrangement on the plastic sheet 401 can also be specifically set according to actual fixing requirements and the subsequent use of the connected device.

[0048] In summary, the above remote monitoring device is as follows Figure 9 As shown, Figure 9 2 is an overall schematic diagram of a remote monitoring device provided according to an embodiment of the present invention.

[0049] Figure 10 Schematic diagram of the connection between the remote monitoring device, the control terminal 6 and the drone group 7 according to an embodiment of the present invention. Figure 10 As shown, as an optional embodiment, the above-mentioned device is connected to the control terminal 6 by signal. In the embodiment, the remote monitoring device as a whole can be connected to the control terminal 6 by signal, or the monitoring device body 1, the connector 2, and the connecting line 3 can be connected to the control terminal 6 by signal separately. The control terminal 6 can also monitor multiple remote monitoring devices in real time at the same time, and can also promptly detect remote monitoring devices with abnormal conditions and perform corresponding emergency treatment. For example, when the connector 2 is stuck inside the connected device and the signal transmitter 209 fixed to the inner wall of the corrugated sleeve 208 is activated and begins to emit an alarm signal, the control terminal can be used to locate the connector 2, achieve positioning and tracking of the device, and promptly stop illegal intrusion into the device.

[0050] As an optional embodiment, the control terminal 6 is connected to the drone group 7 by signal, and the control terminal 6 is used to control the drone group 7. Under normal conditions, the drone group 7 can be used to assist in inspections and other tasks. After the remote monitoring device triggers an alarm, the drone group 7 can quickly reach its designated location based on the control of the control terminal 6, providing auxiliary functions such as positioning to assist in the search for illegally intruded devices.

[0051] It should be noted that the above-mentioned remote monitoring device can be used as a remote monitoring device for on-site operations of a substation.

[0052] The following introduces the remote monitoring device for substation on-site operation scenarios.

[0053] In the substation on-site operation scenario, a special key is entered into the security equipment provided by the substation itself. After accessing the substation management system through the connector 2 and the remote monitoring device body 1, the substation management system will detect the key of the access equipment. When the key is consistent, the technician can use the equipment to perform normal maintenance and upgrades on the substation system. When the technician tries to access the substation using security equipment not provided by the substation, because the non-security equipment cannot provide the pre-entered key, the remote monitoring device body 1 starts the emergency management system, the connector 2 as a whole starts to heat up, and cuts off the power supply of the electromagnetic ring 206. At this time, there is no longer any adsorption effect between the connector 2 and the connecting line 3. At the same time, the heat generated by the connector 2 will melt the low-temperature hot melt adhesive 204, release the constraint on the locking buckle 203, and the locking buckle 203 will move away from the connector body. The body 201 moves in the direction of the connector 2, and the connector 2 is stuck in the non-safety equipment as a whole. At the same time, the signal transmitting device 209 is started and an alarm signal is issued. The substation management system searches for illegal technicians and illegal equipment according to the alarm signal, and promptly stops the illegal intrusion into the substation. When the technician tries to use the connecting wire 3 to pull out the connector 2, since there is no longer an adsorption effect between the connector 2 and the connecting wire 3, the connection between the connector 2 and the connecting wire 3 will be directly disconnected and the connector 2 as a whole will be embedded in the non-safety equipment. It is difficult for the technician to remove the connector 2 from the non-safety equipment. At the same time as the connecting wire 3 is pulled out, the connector 2 stops heating, and the low-temperature hot melt adhesive 204 gradually solidifies, adhering the connector 2 to the illegal equipment. It is difficult for the technician to remove the connector 2 from the illegal equipment in time, and it is not easy to escape the search work of the staff.

[0054] It should be noted that the melting points of all structures in the connector 2 are much higher than the melting point of the low-temperature hot melt adhesive 204 , so that the low-temperature hot melt adhesive 204 is unlikely to affect the normal operation of the connector 2 after melting.

[0055] A static contact 207 is fixedly connected to the bottom plate of the groove of the connecting hole 205. The static contact 207 is located on the inner side of the corrugated sleeve 208, and the static contact 207 needs to be pushed horizontally to take effect, that is, the static contact 207 will not be activated until the signal transmitter 209 is completely in contact with the surface opposite to the static contact 207. The staff can use a device longer than the length of the connecting part 301 to push the corrugated sleeve 208 and the signal transmitter 209, so that the signal transmitter 209 contacts the static contact 207, triggering the static contact 207, so that the connector 2 starts to generate heat again, and the electromagnetic ring 206 is re-energized to take effect. After the low-temperature hot melt adhesive 204 melts again, the connector 2 and the connecting line 3 that have been re-adsorbed can be used to remove the connector 2 from the non-safety device to avoid unnecessary conflicts caused by damage to the non-safety device. The horizontal push of the static contact 207 can prevent illegal intruders from triggering the static contact 207 through non-standard equipment. A compression spring 210 is inserted in the corrugated sleeve 208. The two ends of the compression spring 210 are fixedly connected to the groove bottom plate of the connecting hole 205 and the corrugated sleeve 208 respectively. The compression spring 210 is sleeved on the outside of the signal transmitting device 209. In the absence of external force, the presence of the compression spring 210 can separate the static contact 207 and the signal transmitting device 209, making it less likely that the static contact 207 will fail due to accidental contact. At the same time, the presence of the compression spring 210 can prevent illegal intruders from trying to push the corrugated sleeve 208 through non-standard equipment. The corrugated sleeve 208 and the signal transmitting device 209 are easily overturned due to uneven force, making it difficult for the static contact 207 to be triggered.

[0056] Filling fibers 5 are embedded in the low-temperature hot-melt adhesive 204, and multiple filling fibers 5 are in a three-dimensional spiral shape. Adjacent filling fibers 5 are overlapped with each other to form a three-dimensional spatial structure. After the low-temperature hot-melt adhesive 204 melts, the three-dimensional spatial structure formed by the filling fibers 5 is used to lock the high-viscosity low-temperature hot-melt adhesive 204. After the connector 2 is pulled out of the non-safety device as a whole, it is not easy for the low-temperature hot-melt adhesive 204 to remain in the non-safety device, and it is not easy to damage the non-safety device, thereby avoiding unnecessary conflicts caused by damage to the non-safety device. The filling fibers 5 include a fiber body 501, and the fiber body 501 is a hollow structure, so that the low-temperature hot-melt adhesive 204 will penetrate into the fiber body 501, thereby increasing the locking effect of the multiple filling fibers 5 on the low-temperature hot-melt adhesive 204. Multiple capillary cracks 502 are opened on the fiber body 501, and the multiple capillary cracks 502 are all intersecting, thereby further increasing the locking effect of the multiple filling fibers 5 on the low-temperature hot-melt adhesive 204.

[0057] The outer side of the connector 2 is provided with a plastic sleeve 4, which includes a plastic sheet 401. The plastic sheet 401 is used to separate the low-temperature hot melt adhesive 204 from the connector 2, so that the low-temperature hot melt adhesive 204 is not easy to form residues in the connector 2, thereby avoiding damage to non-safety equipment and causing unnecessary conflicts. A plurality of micropores 402 are drilled on the plastic sheet 401, and the plurality of micropores 402 are evenly distributed on the surface of the plastic sheet 401. A small amount of low-temperature hot melt adhesive 204 can contact and fix the non-safety equipment through the plastic sheet 401. In the process of pulling out the connector 2, even if a small amount of leaked low-temperature hot melt adhesive 204 remains in the non-safety equipment, it is not easy to affect the normal use of the non-safety equipment, thereby avoiding damage to the non-safety equipment and causing unnecessary conflicts.

[0058] Multiple remote monitoring devices are respectively connected to the control terminal 6 by signal. The control terminal 6 is used to monitor the multiple remote monitoring devices in real time, promptly detect any abnormal remote monitoring devices, and perform corresponding emergency processing. The control terminal 6 is signal-connected to the drone group 7. When the drone group 7 is working normally, it can assist in the inspection work of the substation. After the remote monitoring device triggers an alarm, the drone group 7 can quickly reach its position to provide the staff with auxiliary work such as positioning and assist in the search work.
