Abstract

The present invention discloses an intelligent monitoring system for the microgrid power distribution environment. During use, a motor is utilized to drive a shaft rod to rotate, and a pressing rod is driven to rotate synchronously. After the pressing rod contacts a control rod, the control rod is driven to move along a guiding hole and compress a first spring. When the compression amount of the first spring reaches a preset value, it is detected whether the force on the first spring reaches a set threshold and whether the control rod moves to a set position; thus, it can be detected by a sensor whether the force on the first spring reaches the set threshold or the control rod moves to the set position, and the humidity sensor is turned on or off based on this detection signal, enabling the humidity sensor to work intermittently. On the one hand, it can ensure the smooth operation of the humidity monitoring operation, and on the other hand, it can prevent the problems of high energy consumption during long-term operation of the humidity sensor and even damage to the service life of the humidity sensor, and can reduce the energy consumption of the humidity sensor.

[0001] The present invention belongs to the technical field of environmental monitoring, and specifically relates to an intelligent monitoring system for the distribution environment of a microgrid. Background Art

The system also conducts inspection management and maintenance management on the distribution room and electrical equipment through the platform, improving the operation and maintenance efficiency. The system realizes the goal of "unattended and few people on duty" in the distribution room, significantly improving the safety, reliability, and management efficiency of the distribution room. The intelligent monitoring system for the distribution room environment integrates devices such as sensors, data collectors, and communication modules to achieve real-time collection, processing, and monitoring of environmental data such as temperature, humidity, SF6 gas, smoke, and cable trench water level in the distribution room. The intelligent monitoring system for the distribution room environment can solve the problems of long inspection cycle, large blind area, and serious consumption of human resources in the distribution room environment monitoring, and implement long-term, effective, continuous, scientific, accurate, comprehensive, and efficient monitoring of the distribution room environmental quality through communication network technology.

[0014] Further, the tops of the control rod and the extrusion rod are both spherical.

[0015] Further, the moisture absorption plates are annularly arranged in 2N pieces on average, where N is a positive integer greater than or equal to 1.

[0016] Further, the width of the moisture absorption plate along the direction parallel to the shaft rod is smaller than the distance between the two side surfaces of the detection cavity perpendicular to the shaft rod, and the moisture absorption plate is installed on the shaft rod and close to one of the side surfaces of the detection cavity; one end of the moisture absorption plate facing the other side surface of the detection cavity is provided with a sliding groove, and a telescopic plate slidably matched with the sliding groove is arranged in the sliding groove.

[0022] The beneficial effects of the present invention are as follows:

[0023] In the intelligent monitoring system for the microgrid power distribution environment of the present invention, during use, the motor drives the shaft to rotate, and drives the extrusion rod to rotate synchronously. When the extrusion rod contacts the control rod, it drives the control rod to move along the guiding hole and compress the first spring. When the compression amount of the first spring reaches the preset value, it is detected whether the force on the first spring reaches the set threshold and whether the control rod moves to the set position; thus, it can be detected by the sensor whether the force on the first spring reaches the set threshold or the control rod moves to the set position, and the humidity sensor is turned on or off with this detection signal, so that the humidity sensor works intermittently. On the one hand, it can ensure the smooth operation of the humidity monitoring operation, and on the other hand, it can prevent the problem that the humidity sensor consumes high energy during long-term operation and even damages the service life of the humidity sensor, and can reduce the energy consumption of the humidity sensor.

[0024] The present invention also has the following technical effects:

[0025] (1) When the humidity sensor is in the on state, if the sensor detects that the force on the first spring reaches the set threshold or detects that the control rod moves to the set position, the control module controls the humidity sensor to turn off through the drive module; when the humidity sensor is in the off state, if the sensor detects that the force on the first spring reaches the set threshold or detects that the control rod moves to the set position, the control module controls the humidity sensor to turn on through the drive module. That is, when the motor drives the shaft to rotate, in the previous circle, when the extrusion rod contacts the control rod, it drives the control rod to move along the guiding hole and compress the first spring, so that it is detected whether the force on the first spring reaches the set threshold or the control rod moves to the set position. If: at this time, the control module controls the humidity sensor to turn on through the drive module, then in the next circle, when the extrusion rod contacts the control rod and makes it detected whether the force on the first spring reaches the set threshold or the control rod moves to the set position, then at this time the control module controls the humidity sensor to turn off through the drive module; if the control module controls the humidity sensor to turn off through the drive module at this time, then in the next circle, when the extrusion rod contacts the control rod and makes it detected whether the force on the first spring reaches the set threshold or the control rod moves to the set position, then at this time the control module controls the humidity sensor to turn on through the drive module; that is, the intermittent working frequency of the humidity sensor can be controlled by controlling the rotation speed of the motor, which has the advantage of convenient control.

[0026] (2) By setting a sliding groove on the moisture absorption plate, installing a telescopic plate in the sliding groove, and setting the telescopic plate as a magnetic plate; when the humidity sensor is turned on, under the action of the second spring at this time, the telescopic plate retracts into the sliding groove. In this way, since there is a distance between the moisture absorption plate and the telescopic plate and the detection cavity, by driving the moisture absorption plate to rotate through the shaft rod, the external air flow can be quickly introduced into the detection cavity through the moisture absorption plate, and the environmental humidity can be monitored by the humidity sensor, which is more timely and fast, and the humidity monitoring data is relatively more accurate; when the humidity sensor is turned off, the magnetic plate is electrified at this time, and by using the repulsive force generated by the same magnetic pole direction between the magnetic plate and the magnet or the moisture absorption plate made of magnetic material, the telescopic plate can be driven to extend out of the sliding groove and compress the second spring, so that the telescopic plate fits with the inner wall of the detection cavity, playing a sealing effect on the detection cavity, avoiding cavitation caused by the humidity sensor being exposed for a long time, and being able to protect the humidity sensor.

[0027] (3) By setting a climate network module and a frequency control module, the climate network module is used to obtain weather information through the Internet. If the current weather is a weather with little humidity change (such as sunny days and cloudy days, etc.), the frequency control module can be used to control the motor to reduce the rotation frequency. On the one hand, it ensures the normal operation of humidity monitoring, and on the other hand, it can avoid damage caused by the high-frequency operation of the humidity sensor; if the current weather is a weather with large humidity change (such as rain, snow, and fog, etc.), the frequency control module can be used to control the motor to increase the rotation frequency, so that the humidity sensor operates at a high frequency, and thus the real-time data of the environmental humidity can be monitored quickly and timely.

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited are not intended to limit the present invention.

[0038] The intelligent monitoring system for the micro - grid power distribution environment in this embodiment includes an environmental humidity monitoring device and a control system.

[0039] As Figure 1-2 shown, the environmental humidity monitoring device in this embodiment includes a detection chamber 10 and a control chamber 30. A shaft rod 11 rotatably fitted therewith is provided in the detection chamber 10. One end of the shaft rod 11 extends into the control chamber 30, and a motor 12 for driving the shaft rod 11 to rotate is provided in the control chamber 30. In this embodiment, a through port 13 communicating with the outside is provided at one end of the detection chamber 10, and a humidity sensor 14 is installed on the inner wall of the other end surface of the detection chamber 10 opposite to the through port 13. A moisture absorption plate 15 synchronously rotating with the shaft rod 11 is provided on the shaft rod 11. The moisture absorption plate 15 is located in the detection chamber 10 and is used for introducing external air flow.

[0040] As Figure 2-4 shown, a control switch is provided in the control chamber 30 of this embodiment. The control switch is installed on the inner wall of one side of the control chamber 30. The control switch includes a control base 31. A guide hole 32 perpendicular to the shaft rod 11 is provided on the control base 31. A control rod 33 slidably fitted therewith is installed in the guide hole 32. A first spring 34 is provided between the control rod 33 and the bottom of the guide hole 32. An extrusion rod 35 aligned with the control rod 33 is provided on the shaft rod 11, and the lengths of the control rod 33, the first spring 34, and the extrusion rod 35 satisfy:

[0041]

[0042] Among them: is the length of the control rod 33; is the maximum length that the first spring 34 can extend; is the length of the extrusion rod 35; is the radius of the shaft rod 11 at the position where the extrusion rod 35 is provided; is the distance between the bottom of the guide hole 32 and the axis of the shaft rod 11.

[0043] In this way, when the first spring 34 extends to its maximum length, due to the length of the control rod 33 , the maximum length of the first spring 34 and the radius of the shaft rod 11 The sum is less than the distance between the bottom of the guide hole 32 and the axis of the shaft rod 11 , it can avoid interference caused by the contact between the control rod 33 and the outer wall of the shaft rod 11. At the same time, the length of the control rod 33 , the maximum length of the first spring 34 , the length of the extrusion rod 35 and the radius of the shaft rod 11 The sum is greater than the distance between the bottom of the guide hole 32 and the axis of the shaft rod 11 . In this way, when the extrusion rod 35 rotates with the shaft rod 11 to the position where the control switch is located, the extrusion rod 35 can contact the control rod 33 and drive the control rod 33 to compress the first spring 34 and move toward the bottom side of the guide hole 32. In the preferred embodiment of this embodiment, the tops of the control rod 33 and the extrusion rod 35 are both spherical, so that jamming can be prevented when the extrusion rod 35 pushes the control rod 33 to compress the first spring 34 and move.

[0044] In this way, by detecting the force on the first spring 34 or the moving position of the control rod 33, the switch control signal can be obtained.

[0045] Specifically, as Figure 5 shown, the control system of this embodiment includes a control module 36 and a driving module 37 electrically connected to the control module 36. The driving module 37 is used to control the humidity sensor 14 to be turned on or off; a sensor 38 for detecting whether the force on the first spring 34 reaches a set threshold or for detecting whether the control rod 33 moves to a set position is provided in the control base 31. The control module 36 controls the humidity sensor 14 to be turned on or off according to the detection signal detected by the sensor 38 through the driving module 37. Specifically, the detection signal of the force on the first spring 34 can be collected by a pressure sensor, and the moving position of the control rod 33 can be collected by a displacement sensor.

[0046] In a preferred embodiment of the present embodiment, the specific manner in which the control module 36 controls the opening or closing of the humidity sensor 14 according to the detection signal detected by the sensor 38 and through the driving module 37 is as follows: when the humidity sensor 14 is in the open state, if the sensor 38 detects that the force on the first spring 34 reaches a set threshold or detects that the control rod 33 moves to a set position, the control module 36 controls the humidity sensor 14 to close through the driving module 37; when the humidity sensor 14 is in the closed state, if the sensor 38 detects that the force on the first spring 34 reaches a set threshold or detects that the control rod 33 moves to a set position, the control module 36 controls the humidity sensor 14 to open through the driving module 37.

[0047] That is, the working principle of controlling the humidity sensor 14 of the intelligent monitoring system for the microgrid power distribution environment in this embodiment to work intermittently: During humidity monitoring, the motor 12 runs to drive the shaft rod 11 to rotate for the first circle. The shaft rod 11 drives the extrusion rod 35 to rotate around its center. When the extrusion rod 35 rotates to contact and squeeze the control rod 33, the control rod 33 is subjected to the pressure along the axial direction of the guiding hole 32 and compresses the first spring 34. The first spring 34 deforms under force, and the control rod 33 moves toward the bottom side of the guiding hole 32. The control module 36 senses the force of the first spring 34 or senses the movement of the control rod 33 toward the bottom side of the guiding hole 32. When the force of the first spring 34 reaches the set threshold or the control rod 33 moves to the set position, the control module 36 sends a control signal to the driving module 37, so that the driving module 37 controls the humidity sensor 14 to operate, and the humidity sensor 14 senses the humidity in the air to monitor the air humidity. The motor 12 drives the shaft rod 11 to continue rotating, the extrusion rod 35 separates from the control rod 33, and the control rod 33 moves toward the side where the shaft rod 11 is located under the action of the first spring 34, that is, the control rod 33 resets. During this process, the humidity sensor 14 remains in the on state. When the motor 12 drives the shaft rod 11 to continue rotating for the second circle, the extrusion rod 35 rotates to contact and squeeze the control rod 33 again. The control rod 33 is subjected to the pressure along the axial direction of the guiding hole 32 and compresses the first spring 34. The first spring 34 deforms under force, and the control rod 33 moves toward the bottom side of the guiding hole 32. The control module 36 senses the force of the first spring 34 or senses the movement of the control rod 33 toward the bottom side of the guiding hole 32. When the force of the first spring 34 reaches the set threshold or the control rod 33 moves to the set position, the control module 36 sends a control signal to the driving module 37, so that the driving module 37 controls the humidity sensor 14 to close, that is, the humidity sensor 14 stops working. The motor 12 drives the shaft rod 11 to continue rotating, the extrusion rod 35 separates from the control rod 33, and the control rod 33 moves toward the side where the shaft rod 11 is located under the action of the first spring 34, that is, the control rod 33 resets. During this process, the humidity sensor 14 remains in the off state until the control module 36 detects again through the sensor 38 that the force of the first spring 34 reaches the set threshold or the control rod 33 moves to the set position, and then controls the humidity sensor 14 to change the on and off states through the driving module 37. Repeating in this way can achieve the technical purpose of controlling the humidity sensor 14 to work intermittently. On the one hand, it can ensure the smooth operation of the humidity monitoring operation. On the other hand, it can prevent the problem that the humidity sensor 14 consumes high energy during long-term operation, and even damages the service life of the humidity sensor 14, and can reduce the energy consumption of the humidity sensor 14.

[0048] Such as Figure 3As shown in the figure, in this embodiment, 2N wet plates 15 are arranged annularly and evenly, where N is a positive integer greater than or equal to 1. In this embodiment, N = 1. In this way, two parallel wet plates 15 are symmetrically arranged on both sides of the shaft rod 11 with respect to the center, which can improve the air flow exchange efficiency between the outside air and the air flow in the detection chamber 10. On the other hand, by using two parallel wet plates 15, when the shaft rod 11 stops rotating, the upper and lower side surfaces of the detection chamber 10 can be sealed in the radial direction, preventing the humidity sensor 14 from being exposed for a long time and causing cavitation, and protecting the humidity sensor 14.

[0049] In the axial direction of the shaft rod 11, the width of the wet plate 15 in the direction parallel to the shaft rod 11 is smaller than the distance between the two left and right side surfaces of the detection chamber 10 perpendicular to the shaft rod 11. In order to seal the two left and right side surfaces of the detection chamber 10 perpendicular to the shaft rod 11, in this embodiment, the wet plate 15 is installed on the shaft rod 11 and close to one of the side surfaces (left side surface) of the detection chamber 10. At the same time, a sliding groove 16 is provided at one end of the wet plate 15 facing the other side surface (right side surface) of the detection chamber 10, and a telescopic plate 17 that is slidably engaged with the sliding groove 16 is provided in the sliding groove 16. At the same time, the sum of the widths of the telescopic plate 17 and the wet plate 15 in the direction parallel to the shaft rod 11 is greater than the distance between the two side surfaces of the detection chamber 10, which can prevent the telescopic plate 17 from disengaging from the sliding groove 16, as Figure 4 shown in the figure. In this way, when it is necessary to seal the left and right side surfaces of the detection chamber 10, the telescopic plate 17 can be controlled to extend out of the sliding groove 16 and make the telescopic plate 17 contact the side surface (right side surface) of the detection chamber 10; when it is necessary to introduce outside air into the detection chamber 10, the telescopic plate 17 is controlled to retract into the sliding groove 16, so that the air flow can quickly enter the detection chamber 10 under the guiding action of the wet plate 15.

[0050] The method for controlling the telescopic plate 17 to extend out of the sliding groove 16 in this embodiment is as follows: the telescopic plate 17 is a magnetic plate, a magnet is provided in the sliding groove 16 or the wet plate 15 is made of a magnetic material, that is, the wet plate 15 has magnetic poles. The control system includes a magnetic force module 39, and the magnetic force module 39 is used to control the magnetic plate to be energized or de-energized. When the magnetic plate is energized, the magnetic pole direction of the magnetic plate is the same as the magnetic pole direction of the magnet or the wet plate 15 to drive the telescopic plate 17 to extend out of the sliding groove 16.

[0051] Specifically, the magnetic module 39 is electrically connected to the control module 36, and: when the humidity sensor 14 is turned on, the control module 36 controls the magnetic plate to be powered off through the magnetic module 39. At this time, the telescopic plate 17 can be retracted into the sliding groove 16, enabling external air flow to quickly enter the detection chamber 10; when the humidity sensor 14 is turned off, the control module 36 controls the magnetic plate to be powered on through the magnetic module 39. At this time, the magnetic pole direction of the magnetic plate is the same as that of the magnet or the moisture absorption plate 15, which can drive the telescopic plate 17 to extend from the sliding groove 16 and make the telescopic plate 17 contact the side surface (right side surface) of the detection chamber 10, playing a sealing role for the detection chamber 10, preventing the humidity sensor 14 from being exposed for a long time and causing cavitation, and protecting the humidity sensor 14.

[0052] In this embodiment, the method for controlling the telescopic plate 17 to retract from the sliding groove 16 is as follows: guide rails 18 corresponding to the moisture absorption plates 15 one by one are provided on the shaft rod 11. Guide sliders 19 slidably engaged with the guide rails 18 are provided in the guide rails 18. The telescopic plate 17 is mounted on the guide sliders 19. A second spring 20 for applying pressure to drive the telescopic plate 17 to reset and retract into the sliding groove 16 is provided at one end of the guide slider 19 facing away from the moisture absorption plate 15. Thus, when the humidity sensor 14 is turned on, the control module 36 controls the magnetic plate to be powered off through the magnetic module 39. Under the elastic force of the second spring 20, the telescopic plate 17 is driven to retract into the sliding groove 16, enabling external air flow to quickly enter the detection chamber 10; when the humidity sensor 14 is turned off, the control module 36 controls the magnetic plate to be powered on through the magnetic module 39. At this time, the magnetic pole direction of the magnetic plate is the same as that of the magnet or the moisture absorption plate 15. Under the electromagnetic force received by the magnetic plate, the second spring 20 can be compressed and the telescopic plate 17 can be driven to extend from the sliding groove 16 and make the telescopic plate 17 contact the side surface (right side surface) of the detection chamber 10, playing a sealing role for the detection chamber 10, preventing the humidity sensor 14 from being exposed for a long time and causing cavitation, and protecting the humidity sensor 14.

[0053] In a preferred implementation manner of this embodiment, the control system further includes a climate network module 40 and a frequency control module 41. Both the climate network module 40 and the frequency control module 41 are electrically connected to the control module 36, as Figure 5As shown. The climate network module 40 is used to obtain weather information through the network, and the frequency control module 41 controls the rotation frequency of the motor 12 according to the weather information. By setting the climate network module 40 and the frequency control module 41, the climate network module 40 is used to obtain weather information through the Internet. If the current weather is a weather with little humidity change (such as sunny days and cloudy days, etc.), the frequency control module 41 can be used to control the motor 12 to reduce the rotation frequency. On the one hand, it ensures the normal operation of humidity monitoring, and on the other hand, it can prevent the humidity sensor 14 from running at high frequency and being damaged. If the current weather is a weather with large humidity change (such as rain, snow, and fog, etc.), the frequency control module 41 can be used to control the motor 12 to increase the rotation frequency, so that the humidity sensor 14 increases the operation frequency, and thus can quickly and timely monitor the real-time data of the environmental humidity.

[0054] In addition, when the operation frequency of the humidity sensor 14 is high, the power-on frequency of the magnetic plate can also be reduced, that is, after the humidity sensor 14 starts intermittently M (M≥2) times, the control module 36 controls the magnetic plate to be powered on through the magnetic module 39, so that the contact frequency between the telescopic plate 17 and the side surface (right side surface) of the detection cavity 10 can be reduced, the wear between the telescopic plate 17 and the side surface (right side surface) of the detection cavity 10 can be reduced, and at the same time, the operation of the humidity sensor 14 for high-frequency sensing of the environmental humidity will not be affected too much, and the data monitoring is more accurate.

[0055] Specifically, the main content of humidity monitoring of the microgrid power distribution environment intelligent monitoring system in this embodiment is as follows.

[0056] 1. Start the environmental humidity monitoring device:

[0057] The motor 12 starts to run, driving the shaft rod 11 to rotate.

[0058] The extrusion rod 35 on the shaft rod 11 rotates accordingly. When the extrusion rod 35 contacts and squeezes the control rod 33, the control rod 33 slides to the right along the guiding hole 32 of the control switch, and the first spring 34 is deformed by force.

[0059] 2. Control signal transmission:

[0060] The control module 36 senses the force on the first spring 34 or the movement of the control rod 33 through the sensor 38. When the force on the first spring 34 reaches the set threshold or the movement of the control rod 33 reaches the set position, the control module 36 sends a control signal to the drive module 37.

[0061] After receiving the control signal, the drive module 37 controls the humidity sensor 14 to start running.

[0062] 3. Intermittent humidity monitoring:

[0063] When the wet board 15 rotates, it drives the air flow to quickly enter the humidity sensor 14, achieving rapid monitoring of the ambient humidity; the humidity sensor 14 senses the humidity value in the air to monitor the air humidity. The process is as follows:

[0064] After the motor 12 drives the shaft rod 11 to rotate and the extrusion rod 35 leaves the control rod 33, under the reaction force of the first spring 34, the control rod 33 resets to keep the humidity sensor 14 in the open state; at this time, the magnetic force module 39 controls the magnetic plate to cut off the power supply so that the wet board 15 can rotate smoothly, improving the humidity monitoring effect; after the magnetic plate is powered off, the magnetic force disappears, and the second spring 20 pushes the guiding slider 19 to reset, and the magnetic plate resets and retracts into the sliding groove 16;

[0065] When the motor 12 drives the shaft rod 11 to continue rotating and the extrusion rod 35 contacts and squeezes the control rod 33 again, the control rod 33 slides to the right along the guiding hole 32 of the control switch, and the first spring 34 is deformed by the force. The control module 36 senses the force on the first spring 34 or the movement of the control rod 33 through the sensor 38. When the force on the first spring 34 reaches the set threshold or the movement of the control rod 33 reaches the set position, the control module 36 sends a control signal to the drive module 37;

[0066] After the drive module 37 receives the control signal, it controls the humidity sensor 14 to close; at this time, the magnetic force module 39 controls the magnetic plate to be powered on, generating a magnetic force to push the magnetic plate to extend out of the sliding groove 16 and fit against the inner wall of the detection cavity 10, and the second spring 20 is compressed and deformed;

[0067] In this way, the humidity sensor 14 starts and closes intermittently to achieve humidity monitoring.

[0068] During the rotation of the shaft rod 11 driven by the motor 12, the control module 36 sends a control signal to make the humidity sensor 14 start and close intermittently, realizing intermittent humidity monitoring. Intermittent monitoring not only ensures the smooth operation of humidity monitoring but also avoids high energy consumption and reduced lifespan caused by the long-term operation of the humidity sensor 14.

[0069] 4. Climate network module 40 and frequency control module 41:

[0070] The climate network module 40 judges the weather conditions through the network, including snowing, raining, foggy, sunny, cloudy, etc.

[0071] The frequency control module 41 controls the rotation frequency of the motor 12 and the expansion and contraction frequency of the electromagnetic plate according to the weather conditions to adapt to different ambient humidity changes.

[0072] 5. Environmental adaptability adjustment:

[0073] On sunny and cloudy days, the motor 12 rotates at a low frequency, and the humidity sensor 14 operates at a low frequency to avoid damage caused by high-frequency operation.

[0074] On rainy, snowy, and foggy days, the motor 12 rotates at a high frequency, and the humidity sensor 14 operates at a high frequency to quickly monitor the environmental humidity.

[0075] In addition, the intelligent monitoring system for the microgrid power distribution environment in this embodiment can, by setting corresponding sensors and other components, real-time monitor the working environment during microgrid power distribution, such as temperature, humidity, water leakage, water level, harmful gases, etc., and display an alarm when an abnormality is detected.

Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
