With the continuous development of the power system and the advancement of intelligentization, substations, as a key link in power transmission and distribution, are becoming more and more important in terms of safety, reliability and efficiency. In the past, the management and control of substations mostly relied on manual inspections, but with the development and progress of science and technology, the management and control of substations is becoming more and more automated and intelligent.

The operation and maintenance master station system is used to determine in real time whether the received environmental data and electrical operation data meet the preset conditions. When the preset conditions are met, control instructions and alarm information are output.

The invention is suitable for unified operation management and scheduling of multiple substations, multiple drones and fire-fighting robots, improving the level of intelligence and safety and reliability.

[0005] There are many equipment rooms in the substation, such as high-voltage distribution room, low-voltage distribution room, transformer room, etc. Various electrical equipment are installed in the equipment room. In order to ensure the safe and stable operation of the equipment, it is necessary to monitor the humidity and temperature in the room. The substation management and control system in the existing technology usually uses temperature and humidity sensors to monitor the temperature and humidity in the equipment room. Once the temperature and humidity sensor fails, it will not be able to accurately monitor the temperature and humidity in the equipment room, resulting in the inability to detect and warn in time when the temperature or humidity is abnormal in the equipment room, which has certain deficiencies in safety and reliability. Therefore, we propose a smart management and control system for substations. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is: once the temperature and humidity sensor fails, it will be unable to accurately monitor the temperature and humidity in the equipment room, resulting in failure to timely discover and issue an alarm when abnormal temperature or humidity occurs in the equipment room.

[0007] In order to solve the above problems, the present invention provides a smart management and control system for a substation, including a supervision and control center and a plurality of self-inspection monitoring mechanisms, wherein the supervision and control center includes a threshold setting module, a management and control analysis module, and an abnormal alarm module, wherein the threshold setting module is signal-connected to the management and control analysis module, and the management and control analysis module is signal-connected to the abnormal alarm module; The self-inspection monitoring mechanism includes a wall-embedded support tube that penetrates and is embedded in the wall, a front sealing column and a rear sealing column that match the wall-embedded support tube are fixedly installed in the wall-embedded support tube, a middle live sealing column is arranged between the front sealing column and the rear sealing column, and the upper and lower ends of the middle live sealing column are fixedly connected with sealing arc blocks, and the outer walls on the left and right sides of the wall-embedded support tube are provided with entry and exit through holes, and the entry and exit through holes are located between the front sealing column and the rear sealing column, and support plates are arranged on the left and right sides of the middle live sealing column, and the support plates are linked with the middle live sealing column, and a temperature and humidity sensor is fixedly installed on the support plate, and a motor slot is arranged at one end of the front sealing column close to the middle live sealing column, and a drive and regulation motor is fixedly installed in the motor slot, and the output end of the drive and regulation motor is fixedly connected to the middle live sealing column; The temperature and humidity sensor is connected to the control and analysis module signal, and the control and analysis module is connected to the drive motor signal.

The temperature and humidity sensors are used to monitor the temperature and humidity of the corresponding equipment room, and the temperature data and humidity data monitored by the temperature and humidity sensors will be transmitted to the management and analysis module in real time. The management and analysis module is used to analyze the temperature and humidity data according to the temperature and humidity thresholds to determine whether there are abnormalities in the temperature and humidity in the equipment room, and to regularly control the self-test monitoring mechanism to perform self-inspection according to the self-test cycle to determine whether there is a fault in the temperature and humidity sensor. When the temperature data is greater than the temperature threshold or the humidity data is greater than the humidity threshold, the management and analysis module will control the abnormal alarm module to issue an alarm.

[0011] As a further improvement of the present application, the two temperature and humidity sensors in the self-inspection monitoring mechanism are respectively recorded as A and B. When the management and analysis module controls the self-inspection monitoring mechanism to perform self-inspection, it will first record the temperature and humidity data currently monitored by A and B. The two sets of data are recorded as A1 and B1 respectively. Then the drive motor is controlled to drive the middle live seal column to rotate 180 degrees, causing the positions of A and B to be reversed. After the data output of A and B is stable, the temperature and humidity data monitored by A and B at this time are read. The two sets of data are recorded as A2 and B2 respectively. Then A2 is compared with B1, and B2 is compared with A1. When the data difference is greater than the difference threshold, the management and analysis module will control the abnormal alarm module to issue an alarm.

[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method: Figure 1-Figure 6 A smart control system for a substation is shown, including a supervision and control center and multiple self-testing monitoring mechanisms, the supervision and control center includes a threshold setting module, a control and analysis module, and an abnormal alarm module, the threshold setting module is connected to the control and analysis module by signal, the control and analysis module is connected to the abnormal alarm module by signal, the self-testing monitoring mechanism includes a wall-embedded support tube 101 embedded in the wall, the wall-embedded support tube 101 is fixedly installed with a front sealing column 102 and a rear sealing column 103 matching therewith, the front sealing column A middle live sealing column 104 is arranged between the front sealing column 102 and the rear sealing column 103, and the upper and lower ends of the middle live sealing column 104 are fixedly connected with sealing arc blocks 105, the diameters of the front sealing column 102 and the rear sealing column 103 are equal and equal to the inner diameter of the wall-embedded support tube 101, the diameter of the middle live sealing column 104 is smaller than the diameter of the front sealing column 102, and the middle live sealing column 104 is slidably sealed with the front sealing column 102 and the rear sealing column 103, the sealing arc block 105 is arranged in a fan shape matching the front sealing column 102, and the sealing The arc block 105 is slidably sealed and connected to the front sealing column 102, the rear sealing column 103 and the wall-embedded support tube 101. The wall-embedded support tube 101, the front sealing column 102 and the rear sealing column 103 are all sealed and fixedly connected to the wall. The outer walls on the left and right sides of the wall-embedded support tube 101 are provided with entry and exit holes 106, and the entry and exit holes 106 are located between the front sealing column 102 and the rear sealing column 103. The left and right sides of the middle live sealing column 104 are provided with support plates 107, and the support plates 107 are connected to the middle live sealing column 104. The support plate 107 is movable (in the present embodiment, the support plate 107 is directly fixedly connected to the middle live sealing column 104), a temperature and humidity sensor 108 is fixedly mounted on the support plate 107, a motor slot 109 is provided at one end of the front sealing column 102 close to the middle live sealing column 104, a drive motor 110 is fixedly mounted in the motor slot 109, an output end of the drive motor 110 is fixedly connected to the middle live sealing column 104, the temperature and humidity sensor 108 is signal-connected to the control and analysis module, and the control and analysis module is signal-connected to the drive motor 110.

[0022] The wall is a common wall of adjacent equipment rooms (for an independent equipment room with no other rooms next to it, the self-test monitoring mechanism can be installed on any wall of the equipment room, so that the two temperature and humidity sensors 108 are located indoors and outdoors respectively), the threshold setting module is used to set the temperature threshold, humidity threshold, self-test cycle, and difference threshold (the difference threshold includes a temperature difference threshold corresponding to the temperature and a humidity difference threshold corresponding to the humidity). Those skilled in the art can reasonably set the temperature threshold, humidity threshold, self-test cycle, and difference threshold through the threshold setting module according to actual conditions. The temperature and humidity sensor 108 is used to monitor the temperature and humidity of the corresponding equipment room, and the temperature data and humidity data monitored by the temperature and humidity sensor 108 will be transmitted to the management and control analysis module in real time. The management and control analysis module is used to analyze the temperature and humidity data according to the temperature and humidity thresholds to determine whether the temperature and humidity in the equipment room are abnormal, and regularly control the self-test monitoring mechanism to perform self-test according to the self-test cycle to determine whether the temperature and humidity sensor 108 is faulty. When the temperature data is greater than the temperature threshold or the humidity data is greater than the humidity threshold, the management and control analysis module will control the abnormal alarm module to alarm (the alarm method can be sound and light, SMS, email, etc.); The two temperature and humidity sensors 108 in the self-test monitoring mechanism are respectively denoted as A and B. When the management and control analysis module controls the self-test monitoring mechanism to perform self-test, it first records the temperature and humidity data currently monitored by A and B. The two sets of data are respectively denoted as A1 and B1 (A1 includes the temperature data and humidity data monitored by A, and B1 and A2 and B2 below are similar). Then, the drive motor 110 is controlled to drive the middle active seal column 104 to rotate 180 degrees, so that the positions of A and B are reversed. After the output of A and B data is stable, the temperature and humidity data monitored by A and B at this time are read. The two sets of data are respectively denoted as A2 and B2. Then, A2 is compared with B1, and B2 is compared with A1. When the data difference is greater than the difference threshold, it means that at least one of A and B is faulty. The management and control analysis module will control the abnormal alarm module to sound an alarm. In addition, during the self-inspection process, if the self-inspection is completed, the management and control analysis module will control the drive motor 110 to drive the middle live seal column 104 to rotate 180 degrees again, causing A and B to reset; therefore, through the setting of the self-inspection monitoring mechanism and the supervision and control center, the supervision and control center can control the self-inspection monitoring mechanism to perform self-inspection regularly, and determine whether the temperature and humidity sensor 108 is faulty through self-inspection, and can automatically sound an alarm when a fault is detected in the temperature and humidity sensor 108, prompting relevant technical personnel to perform corresponding maintenance and processing in a timely manner, thereby ensuring the safety and reliability of the system, avoiding the failure of the temperature and humidity sensor 108 to timely detect the temperature and humidity abnormalities between the equipment, and thus improving the safety and reliability of the substation operation.

[0023] The threshold setting module is also used to set the duration threshold and the fluctuation threshold (the fluctuation threshold includes the temperature fluctuation threshold corresponding to the temperature and the humidity fluctuation threshold corresponding to the humidity). The fluctuation threshold is less than the difference threshold. Before starting the self-inspection, that is, after the time from the last self-inspection reaches the self-inspection cycle, the control and analysis module will first count according to the duration threshold and analyze the temperature and humidity data monitored by A and B. During the timing process, when the fluctuation of the temperature and humidity data monitored by A and B is greater than the fluctuation threshold, the control and analysis module will restart the timing until the timing duration reaches the timing threshold. Then the control and analysis module will control the self-inspection monitoring mechanism to perform self-inspection, so that the control and analysis module will control the self-inspection monitoring mechanism to perform self-inspection when the temperature and humidity are relatively stable, thereby improving the accuracy and reliability of the self-inspection and greatly reducing the occurrence of misjudgment.

[0024] The second implementation method: Figure 7-Figure 8 The invention shows a smart control system for a substation. Different from the first embodiment, the self-inspection monitoring mechanism also includes a monitoring and self-adjusting component, which includes a telescopic adjustment groove 201 provided in the middle live sealing column 104 and a telescopic drive adjustment groove 204 provided in the rear sealing column 103. A pair of piston blocks 202 are provided in the telescopic adjustment groove 201 and are slidably and sealedly connected thereto. One end of the piston block 202 is fixedly connected to a linkage rod 203. The linkage rod 203 passes through the outer wall of the telescopic adjustment groove 201 and extends to be fixedly connected to the support plate 107. The linkage rod 203 is slidably and sealedly connected to the outer wall of the telescopic adjustment groove 201. A piston plate 205 is provided in the retractable drive and adjustment groove 204 and is slidably and sealably connected thereto. An electric push rod 206 is fixedly installed in the telescopic drive and adjustment groove 204. The output end of the electric push rod 206 is fixedly connected to the piston plate 205. An air duct 207 is connected between the telescopic drive and adjustment groove 204 and the telescopic adjustment groove 201. A pair of piston blocks 202 are respectively located on the left and right sides of the air duct 207. The linkage rod 203 is located at the end of the piston block 202 away from the air duct 207. The management and control analysis module is connected to the electric push rod 206 by signal. The support plate 107 and the temperature and humidity sensor 108 can pass through the inlet and outlet through-hole 106 to the outside of the wall-embedded support tube 101.

[0025] When working, the control and analysis module will control the electric push rod 206 to push the piston plate 205 to move towards the direction close to the telescopic adjustment groove 201, causing the piston block 202 and the linkage rod 203 to move away from the air duct 207, and the support plate 107 and the temperature and humidity sensor 108 to move away from the middle live seal column 104 (the movement of the piston plate 205 will push the air, so that part of the air flows into the telescopic adjustment groove 201 through the air duct 207, thereby pushing the piston block 202 to move away from the air duct 207) until the temperature and humidity sensor 108 is in a state of being ... The sensor 108 passes through the inlet and outlet hole 106 to the outside of the wall-mounted support tube 101, so that the temperature and humidity sensor 108 can better monitor the temperature and humidity between the equipment. During self-test, the control and analysis module will first control the electric push rod 206 to pull the piston plate 205 to reset before controlling the drive motor 110 to drive the middle live seal column 104 to rotate and adjust, so as to pull the support plate 107 and the temperature and humidity sensor 108 back to the inside of the wall-mounted support tube 101 (when the piston block 202 moves away from the air guide tube 207, the piston block 202 is away from the side of the air guide tube 207). The air will be compressed. When the electric push rod 206 pulls the piston plate 205 to reset, the piston block 202 can pull the temperature and humidity sensor 108 back to the inside of the wall-embedded support tube 101 under the action of air pressure). After rotation and adjustment, the control and analysis module will control the electric push rod 206 to push the piston plate 205 again to move the temperature and humidity sensor 108 to the outside of the wall-embedded support tube 101. After the self-test is completed, the control and analysis module will control the electric push rod 206 to pull the piston plate 205 again to return the temperature and humidity sensor 108 to the inside of the wall-embedded support tube 101, and then The drive motor 110 is controlled to drive the middle live seal column 104 to rotate 180 degrees. Finally, the electric push rod 206 is controlled to push the piston plate 205 to move the temperature and humidity sensor 108 to the outside of the wall-embedded support tube 101. Therefore, through the setting of the monitoring self-adjusting component, the temperature and humidity sensor 108 can automatically extend to the outside of the wall-embedded support tube 101 and automatically return to the inside of the wall-embedded support tube 101. Therefore, without affecting the self-inspection, the temperature and humidity sensor 108 can better monitor the temperature and humidity between the equipment, thereby improving the accuracy of monitoring.

[0026] See also Figure 7The monitoring self-adjusting component also includes a magnet block 208 and two cleaning conduits 209. The magnet block 208 is fixedly installed in the telescopic adjustment groove 201, and the magnet block 208 is located between a pair of piston blocks 202. An iron block is embedded in the piston block 202. The two cleaning conduits 209 are respectively located on the left and right sides of the middle live seal column 104. One end of the cleaning conduit 209 is connected to the inside of the telescopic adjustment groove 201, and the other end of the cleaning conduit 209 faces the temperature and humidity sensor 108. The end of the cleaning conduit 209 facing the temperature and humidity sensor 108 is fixedly connected to the support plate 107 through a connector. The cleaning conduit 209 is made of a corrugated hose. When the electric push rod 206 pushes the piston plate 205 to cause the piston block 202 to move away from the air guide pipe When the electric push rod 206 pulls the piston plate 205, the magnetic attraction between the magnet block 208 and the iron block can pull the piston block 202, thereby ensuring that the temperature and humidity sensor 108 will be pulled back to the inside of the wall-embedded support tube 101. Therefore, through the arrangement of the magnet block 208 and the cleaner duct 209, the dust on the temperature and humidity sensor 108 can be automatically cleaned during self-inspection to prevent dust from affecting the monitoring accuracy of the temperature and humidity sensor 108, thereby further improving the reliability of the system.

[0027] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
