[0006] Further, when the humidity sensor is in the on state, if the sensor detects that the force on the first spring reaches a set threshold or detects that the control rod moves to a set position, the control module controls the humidity sensor to be turned off through the driving module; when the humidity sensor is in the off state, if the sensor detects that the force on the first spring reaches a set threshold or detects that the control rod moves to a set position, the control module controls the humidity sensor to be turned on through the driving module.

[0007] Furthermore, the top ends of the control rod and the extrusion rod are both configured as spherical surfaces.

[0008] Furthermore, the wet plates are evenly distributed in a ring shape in 2N pieces, wherein N is a positive integer greater than or equal to 1.

[0015] The beneficial effects of the present invention are: The microgrid power distribution environment intelligent monitoring system of the present invention, when in use, utilizes a motor to drive the shaft rod to rotate, and drives the extrusion rod to rotate synchronously. When the extrusion rod contacts the control rod, the control rod is driven to move along the guide hole and compress the first spring. When the compression amount of the first spring reaches a preset value, the force on the first spring reaches a set threshold and the control rod moves to a set position. In this way, the sensor can be used to detect whether the force on the first spring reaches a set threshold or the control rod moves to a set position, and the humidity sensor is turned on or off by using this detection signal, so that the humidity sensor works intermittently. On the one hand, it can ensure that the humidity monitoring operation can run smoothly, and on the other hand, it can prevent the humidity sensor from consuming high energy due to long-term operation, and even damage the service life of the humidity sensor, and can reduce the energy consumption of the humidity sensor.

[0016] The present invention also has the following technical effects: (1) When the humidity sensor is in the on state, if the sensor detects that the force on the first spring reaches a set threshold or detects that the control rod moves to a set position, the control module controls the humidity sensor to be turned off through the driving module; when the humidity sensor is in the off state, if the sensor detects that the force on the first spring reaches a set threshold or detects that the control rod moves to a set position, the control module controls the humidity sensor to be turned on through the driving module. That is, when the motor drives the shaft to rotate, in the previous circle, after the extrusion rod contacts the control rod, the control rod is driven to move along the guide hole and compress the first spring to determine whether the force on the first spring reaches a set threshold or the control rod moves to a set position. If: at this time, the control module controls the humidity sensor to be turned on through the drive module, then in the next circle, when the extrusion rod contacts the control rod and determines whether the force on the first spring reaches a set threshold or the control rod moves to a set position, the control module controls the humidity sensor to be turned off through the drive module; at this time, the control module controls the humidity sensor to be turned off through the drive module, then in the next circle, when the extrusion rod contacts the control rod and determines whether the force on the first spring reaches a set threshold or the control rod moves to a set position, the control module controls the humidity sensor to be turned on through the drive module; that is, the intermittent working frequency of the humidity sensor is controlled by controlling the rotation speed of the motor, which has the advantage of convenient control.

[0017] (2) A sliding groove is provided on the moisture collecting plate, and a telescopic plate is installed in the sliding groove, and the telescopic plate is set as a magnetic plate; when the humidity sensor is turned on, the telescopic plate retracts into the sliding groove under the action of the second spring. In this way, since there is a gap between the moisture collecting plate and the telescopic plate and the detection chamber, the moisture collecting plate is driven to rotate by the shaft rod, so that the external airflow can quickly enter the detection chamber through the moisture collecting plate, and the environmental humidity is monitored by the humidity sensor, the monitoring 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 energized at this time, and the repulsive force generated by the same magnetic pole direction of the magnetic plate and the magnet or the moisture collecting plate made of magnetic material can be used to drive the telescopic plate 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 chamber, and the detection chamber is sealed, thereby preventing the humidity sensor from being exposed for a long time and causing cavitation, and protecting the humidity sensor.

[0018] (3) By setting up 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 one with little humidity change (such as sunny days and cloudy days), the frequency control module can be used to control the motor to reduce the rotation frequency. On the one hand, this ensures the normal operation of humidity monitoring, and on the other hand, it can prevent the humidity sensor from being damaged due to high-frequency operation. If the current weather is one with large humidity changes (such as rain, snow, and heavy fog), the frequency control module can be used to control the motor to increase the rotation frequency, so that the humidity sensor can operate at a high frequency, thereby enabling the real-time monitoring of environmental humidity data to be carried out quickly and timely.

DETAILED DESCRIPTION

[0021] The present invention is 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 implement it, but the embodiments are not intended to limit the present invention.

[0022] The microgrid power distribution environment intelligent monitoring system of this embodiment includes an environmental humidity monitoring device and a control system.

[0023] like Figure 1-2 As shown, the environmental humidity monitoring device of this embodiment includes a detection chamber 10 and a control chamber 30. The detection chamber 10 is provided with a shaft 11 that rotates with the detection chamber 10. One end of the shaft 11 extends into the control chamber 30. The control chamber 30 is provided with a motor 12 for driving the shaft 11 to rotate. In this embodiment, one end of the detection chamber 10 is provided with a through hole 13 that communicates with the outside world. A humidity sensor 14 is installed on the inner wall of the other end face of the detection chamber 10 opposite to the through hole 13. The shaft 11 is provided with a moisture extraction plate 15 that rotates synchronously with the shaft 11. The moisture extraction plate 15 is located in the detection chamber 10 and is used to introduce external airflow.

[0024] like Figure 2-4 As shown, a control switch is provided in the control chamber 30 of this embodiment, and 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, and a guide hole 32 perpendicular to the shaft 11 is provided on the control base 31. A control rod 33 slidingly matched with the shaft 11 is installed in the guide hole 32, and 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 11, and the lengths of the control rod 33, the first spring 34 and the extrusion rod 35 meet the following conditions: in: is the length of the control rod 33; is the maximum length to which the first spring 34 can be extended; is the length of the extrusion rod 35; is the radius of the shaft 11 at the position where the extrusion rod 35 is provided; It is the distance between the bottom of the guide hole 32 and the axis of the shaft rod 11.

[0025] Thus, when the first spring 34 is extended to its maximum length, the length of the control rod 33 , the longest length of the first spring 34 and the radius of the shaft 11 The sum is less than the distance between the bottom of the guide hole 32 and the axis of the shaft 11 , which can avoid the interference 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 is , the longest length of the first spring 34 , Extrusion rod 35 length and the radius of the shaft 11 The sum is greater than the distance between the bottom of the guide hole 32 and the axis of the shaft 11 In this way, when the extrusion rod 35 rotates to the position where the control switch is located along with the shaft 11, 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 of the guide hole 32. In the preferred implementation of this embodiment, the top ends of the control rod 33 and the extrusion rod 35 are both set as spherical surfaces, so that the extrusion rod 35 can prevent the control rod 33 from being stuck when it compresses the first spring 34 and moves.

[0026] In this way, the switch control signal can be obtained by detecting the force of the first spring 34 or the moving position of the control rod 33.

[0027] Specifically, Figure 5 As shown, the control system of this embodiment includes a control module 36 and a driving module 37 electrically connected to the control module 36, and the driving module 37 is used to control the humidity sensor 14 to be turned on or off; a sensor 38 is provided in the control base 31 for detecting whether the force applied to the first spring 34 reaches a set threshold or for detecting whether the control rod 33 moves to a set position, and the control module 36 controls the humidity sensor 14 to be turned on or off through the driving module 37 according to the detection signal obtained by the sensor 38. Specifically, the detection signal of the force applied to 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.

[0028] In the preferred implementation manner of the present embodiment, the control module 36 controls the humidity sensor 14 to be turned on or off through the driving module 37 according to the detection signal obtained by the sensor 38. The specific manner is as follows: when the humidity sensor 14 is in the on 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 be turned off through the driving module 37; when the humidity sensor 14 is in the off 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 be turned on through the driving module 37.

[0029] That is, the working principle of the intermittent operation of the humidity sensor 14 in the microgrid power distribution environment intelligent monitoring system of this embodiment is as follows: during humidity monitoring, the motor 12 runs to drive the shaft 11 to rotate for the first circle, and the shaft 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 pressure along the axial direction of the guide hole 32 and compresses the first spring 34. The first spring 34 is deformed by the force, and the control rod 33 moves toward the bottom of the guide hole 32. The control module 36 senses the force of the first spring 34 or senses the control rod 33 moving toward the guide hole. The hole 32 moves to one side of the bottom of the hole; 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 drive module 37, so that the drive module 37 controls the humidity sensor 14 to operate, and senses the humidity in the air through the humidity sensor 14 to monitor the air humidity; the motor 12 drives the shaft 11 to continue to rotate, the extrusion rod 35 is separated from the control rod 33, and the control rod 33 moves toward the side where the shaft 11 is located under the action of the first spring 34, that is, the control rod 33 is reset; during this process, the humidity sensor 14 remains in the open state; when The motor 12 drives the shaft 11 to continue to rotate for the second circle. When the extrusion rod 35 rotates again to contact and squeeze the control rod 33, the control rod 33 is subjected to pressure in the axial direction of the guide hole 32 and compresses the first spring 34. The first spring 34 is deformed by the force, and the control rod 33 moves toward the bottom of the guide hole 32. The control module 36 senses the force of the first spring 34 or the movement of the control rod 33 toward the bottom of the guide hole 32. When the force of the first spring 34 reaches a set threshold or the control rod 33 moves to a set position, the control module 36 sends a control signal to the drive module 3 7, the driving module 37 controls the humidity sensor 14 to turn off, that is, the humidity sensor 14 stops working; the motor 12 drives the shaft 11 to continue to rotate, the extrusion rod 35 is separated from the control rod 33, and the control rod 33 moves toward the side where the shaft 11 is located under the action of the first spring 34, that is, the control rod 33 is reset; in this process, the humidity sensor 14 remains in a closed state until the control module 36 detects 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 again, and then controls the humidity sensor 14 to change the open and closed state through the driving module 37. In this way, the technical purpose of controlling the humidity sensor 14 to work intermittently can be achieved. On the one hand, it can ensure that the humidity monitoring operation can run smoothly, and on the other hand, it can prevent the humidity sensor 14 from consuming high energy for a long time, and even damage the service life of the humidity sensor 14, and reduce the energy consumption of the humidity sensor 14.

[0030] like Figure 3As shown, in this embodiment, the wet plates 15 are evenly distributed in a ring and are set to 2N pieces, wherein N is a positive integer greater than or equal to 1. In this embodiment, N=1. In this way, the two parallel wet plates 15 are respectively arranged on both sides of the shaft 11 in a centrally symmetrical manner, which can accelerate the exchange efficiency between the external airflow and the airflow in the detection chamber 10. On the other hand, by using the two parallel wet plates 15, when the shaft 11 stops rotating, the upper and lower sides of the detection chamber 10 can also be sealed in the radial direction to prevent the humidity sensor 14 from being exposed for a long time and causing cavitation, which can protect the humidity sensor 14.

[0031] In the axial direction of the shaft 11, the width of the wet plate 15 in the direction parallel to the shaft 11 is smaller than the distance between the two left and right sides of the detection chamber 10 perpendicular to the shaft 11. In order to seal the two left and right sides of the detection chamber 10 perpendicular to the shaft 11, the wet plate 15 is installed on the shaft 11 in this embodiment close to one side (left side) of the detection chamber 10, and a sliding groove 16 is provided at one end of the wet plate 15 facing the other side (right side) of the detection chamber 10, and a telescopic plate 17 slidably matched 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 11 is greater than the distance between the two side sides of the detection chamber 10, so as to prevent the telescopic plate 17 from detaching from the sliding groove 16. Figure 4 In this way, when the left and right sides of the detection chamber 10 need to be sealed, the telescopic plate 17 can be controlled to extend from the sliding groove 16 and make the telescopic plate 17 contact the side (right side) of the detection chamber 10; when the external airflow needs to be introduced into the detection chamber 10, the telescopic plate 17 is controlled to retract into the sliding groove 16, so that the airflow can quickly enter the detection chamber 10 under the guidance of the wet plate 15.

[0032] In this embodiment, the telescopic plate 17 is controlled to extend from the sliding groove 16 in the following manner: 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 a magnetic pole. The control system includes a magnetic module 39, which is used to control the power on or off of the magnetic plate, and when the magnetic plate is powered on, 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 from the sliding groove 16.

[0033] 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 which time the telescopic plate 17 can be retracted into the sliding groove 16, so that the external airflow can 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 which time the magnetic pole direction of the magnetic plate is the same as the magnetic pole direction of the magnet or the wet plate 15, which can drive the telescopic plate 17 to extend out of the sliding groove 16 and make the telescopic plate 17 contact with the side (right side) of the detection chamber 10, which can seal the detection chamber 10 and prevent the humidity sensor 14 from being exposed for a long time and causing cavitation, thereby protecting the humidity sensor 14.

[0034] The method of controlling the retractable plate 17 to retract from the sliding groove 16 in this embodiment is as follows: a guide track 18 is provided on the shaft rod 11 in one-to-one correspondence with the moisture extraction plate 15, a guide slider 19 is provided in the guide track 18 and slidably cooperates with the retractable plate 17, the retractable plate 17 is mounted on the guide slider 19, and a second spring 20 is provided at one end of the guide slider 19 facing away from the moisture extraction plate 15 to drive the retractable plate 17 to reset and retract into the sliding groove 16. In this way, 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, and under the elastic force of the second spring 20, drives the telescopic plate 17 to retract into the sliding groove 16, so that the external airflow can 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 the magnetic pole direction of the magnet or the wet plate 15. Under the action of 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 out of the sliding groove 16, and the telescopic plate 17 can be made to contact the side (right side) of the detection chamber 10, which can seal the detection chamber 10, prevent the humidity sensor 14 from being exposed for a long time and causing cavitation, and protect the humidity sensor 14.

[0035] In a preferred implementation of this embodiment, the control system further includes a climate network module 40 and a frequency control module 41, and the climate network module 40 and the frequency control module 41 are both electrically connected to the control module 36, such 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 to ensure the normal operation of humidity monitoring, and on the other hand to avoid the humidity sensor 14 from being damaged by high-frequency operation; if the current weather is a weather with large humidity changes (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 operating frequency, so that the real-time data of the environmental humidity can be quickly and timely monitored.

[0036] In addition, when the operating 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 is intermittently started M times (M≥2), the control module 36 is used to control the power-on of the magnetic plate through the magnetic module 39, thereby reducing the contact frequency between the telescopic plate 17 and the side surface (right side surface) of the detection chamber 10, reducing the wear between the telescopic plate 17 and the side surface (right side surface) of the detection chamber 10, and at the same time, the high-frequency sensing of the ambient humidity by the humidity sensor 14 will not be greatly affected, and data monitoring will be more accurate.

[0037] Specifically, the main contents of humidity monitoring performed by the microgrid power distribution environment intelligent monitoring system of this embodiment are as follows.

[0038] 1. Start the environmental humidity monitoring device: The motor 12 starts to run, driving the shaft 11 to rotate.

[0039] 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 guide hole 32 of the control switch, and the first spring 34 is deformed by the force.

[0040] 2. Control signal transmission: The control module 36 senses the force of the first spring 34 or the movement of the control rod 33 through the sensor 38. When the force of the first spring 34 reaches a set threshold or the movement of the control rod 33 reaches a set position, the control module 36 sends a control signal to the drive module 37.

[0041] After receiving the control signal, the driving module 37 controls the humidity sensor 14 to start operating.

[0042] 3. Intermittent humidity monitoring: When the wet plate 15 rotates, it drives the airflow to quickly enter the humidity sensor 14, so as to realize the rapid monitoring of the environmental humidity; the humidity value in the air is sensed by the humidity sensor 14, so as to monitor the air humidity. The process is as follows: After the motor 12 drives the shaft 11 to rotate and causes the extrusion rod 35 to leave the control rod 33, the control rod 33 is reset under the reaction force of the first spring 34, and the humidity sensor 14 is controlled to remain in the open state; at this time, the magnetic module 39 controls the magnetic plate to be powered off so that the wet plate 15 can rotate smoothly, thereby improving the humidity monitoring effect; after the magnetic plate is powered off, the magnetic force disappears, and the second spring 20 pushes the guide slider 19 to reset, and the magnetic plate is reset and retracted into the sliding groove 16; The motor 12 drives the shaft 11 to continue rotating, and when the extrusion rod 35 contacts and squeezes the control rod 33 again, the control rod 33 slides to the right along the guide hole 32 of the control switch, and the first spring 34 is deformed by force. The control module 36 senses the force of the first spring 34 or the movement of the control rod 33 through the sensor 38. When the force of the first spring 34 reaches a set threshold or the movement of the sensing control rod 33 reaches a set position, the control module 36 sends a control signal to the drive module 37; After receiving the control signal, the driving module 37 controls the humidity sensor 14 to be turned off; at this time, the magnetic module 39 controls the magnetic plate to be energized, generating a magnetic force to push the magnetic plate out of the sliding slot 16 and fit with the inner wall of the detection chamber 10, and the second spring 20 is compressed and deformed; In this way, the humidity sensor 14 is intermittently started and shut down to achieve humidity monitoring.

[0043] When the motor 12 drives the shaft 11 to rotate, the control module 36 sends a control signal to intermittently start and shut down the humidity sensor 14 to achieve 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 long-term operation of the humidity sensor 14.

[0044] 4. Climate network module 40 and frequency control module 41: The climate network module 40 determines weather conditions through the network, including snow, rain, fog, sunny days, cloudy days, etc.

[0045] 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 weather conditions to adapt to different environmental humidity changes.

[0046] 5. Environmental adaptability adjustment: On sunny or 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.

[0047] When it is raining, snowing or foggy, the motor 12 rotates at a high frequency and the humidity sensor 14 operates at a high frequency to quickly monitor the ambient humidity.

[0048] In addition, the microgrid power distribution environment intelligent monitoring system of this embodiment can monitor the working environment of the microgrid power distribution, such as temperature, humidity, water leakage, water level, harmful gases, etc. in real time by setting corresponding sensors and other components, and display an alarm when an abnormality is detected.

[0049] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
