Description

Technical Field

[0001] The present invention relates to the technical field of power cabinets, and in particular to an intelligent dehumidification system for power cabinets based on the Internet of Things. Background Art

[0002] A power cabinet is a device that performs functions such as power distribution, control, protection and monitoring. It plays a vital role in the power system and is widely used in large buildings, factories, power stations and other places. During long-term use, the internal electrical components of the power cabinet will generate more heat, which will cause the temperature inside the cabinet to rise. In order to ensure the normal operation of the power cabinet, it is usually necessary to open ventilation holes to ensure heat dissipation inside the cabinet.

[0003] In the existing power cabinet, when vents are opened to ensure heat dissipation, humid air from the outside can enter the cabinet through the vents simultaneously with the heat dissipation process of the power cabinet, thereby causing the humidity in the cabinet to increase and causing moisture, affecting the normal operation of the power cabinet. However, dehumidification in the cabinet usually needs to be carried out after moisture occurs, and it is difficult to prevent moisture problems in the cabinet in advance, which makes the power cabinet easily damaged by moisture problems.

[0004] To this end, we propose an intelligent dehumidification system for power cabinets based on the Internet of Things. Summary of the invention

[0005] The main purpose of the present invention is to provide an intelligent dehumidification system for power cabinets based on the Internet of Things to overcome the problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides an intelligent dehumidification system for power cabinets based on the Internet of Things, comprising an outer cabinet, an inner cabinet is fixedly installed on the inner top surface of the outer cabinet, a movable plate is movably installed on the lower surface of the inner cabinet, sealing blocks are fixedly installed on the upper parts of both sides of the outer surface of the movable plate, electric support rods are fixedly installed on the four corners of the lower surface of the movable plate, a first dehumidification box is fixedly installed on the middle part of the lower surface of the movable plate, refrigeration pipes are fixedly installed on the upper parts of both sides of the inner surface of the first dehumidification box, openings are opened in the middle parts of both sides of the outer surface of the first dehumidification box, a micro air pump is fixedly installed on the inner surface of the first dehumidification box through the opening, and an extrusion frame is fixedly installed on the lower part of the inner surface of the first dehumidification box;

[0012] As a further improvement of the present invention, a discharge port is provided through the middle of the lower surface of the second dehumidification box, and the discharge port is aligned with the discharge hole.

[0013] As a further improvement of the present invention, the data processing unit monitors, processes and analyzes the environmental factor data, and the specific process is as follows:

[0014] Monitor the environmental factor data to obtain the real-time humidity, temperature and air flow velocity values, where the real-time humidity value is divided into the humidity value outside the cabinet and the humidity value inside the cabinet. Substitute the humidity value outside the cabinet and the humidity value inside the cabinet into the formula P1=|WS×β1-NS×β2| to obtain the humidity difference ratio P1, where WS and NS are the real-time values ​​of the humidity value outside the cabinet and the humidity value inside the cabinet, respectively, and β1 and β2 represent the set proportional coefficient factors respectively;

[0015] Set the humidity threshold WS' outside the cabinet and the humidity threshold NS' inside the cabinet, and substitute into the formula Get the value of the humidity threshold ratio outside the cabinet WA' and the value of the humidity threshold ratio inside the cabinet WB', take the maximum value to the minimum value to form the humidity threshold interval outside the cabinet and the humidity threshold interval inside the cabinet, and substitute the real-time humidity values ​​WS and NS outside the cabinet into the formula The humidity proportion value WA outside the cabinet and the humidity proportion value WB inside the cabinet are obtained, and α1 and α2 are respectively represented as the set proportional coefficient factors. The humidity proportion value WA outside the cabinet and the humidity proportion value WB inside the cabinet are matched with the corresponding threshold interval. If the humidity proportion values ​​WA outside the cabinet and WB inside the cabinet are both within the corresponding threshold interval, it indicates that the match is successful, and the humidity difference ratio P1 is a normal difference. If any value of the humidity proportion values ​​WA outside the cabinet and WB inside the cabinet is outside the corresponding threshold interval, it indicates that the match fails, and the humidity difference ratio P1 is an abnormal difference. The abnormal difference is combined with the real-time humidity values ​​inside and outside the cabinet to generate a corresponding dehumidification operation instruction, which is transmitted to the control module.

[0016] As a further improvement of the present invention, the data processing unit further includes a humidity monitoring module, a temperature monitoring module and an airflow monitoring module;

[0019] The airflow monitoring module is connected to the micro air pump by wireless signal, and determines the operating power of the micro air pump by monitoring the flow velocity value of the airflow transmitted by the micro air pump.

[0020] As a further improvement of the present invention, the temperature monitoring module obtains the real-time temperature value and the data processing unit processes and analyzes it, specifically:

[0021] Set the internal cabinet temperature threshold NW' and substitute it into the formula WC'=NW'×γ1 to obtain the internal cabinet temperature threshold proportion value WC', select the maximum value to the minimum value to form the internal cabinet temperature threshold interval, substitute the real-time temperature value NW into the formula WC=NW×γ2 to obtain the internal cabinet temperature proportion value WC, γ1 and γ2 represent the set proportional coefficient factors, match the temperature proportion value WC with the temperature threshold interval, if the real-time temperature proportion value is within the temperature threshold interval, it indicates that the match is successful, and the real-time temperature value is a normal temperature value, if the real-time temperature proportion value is outside the temperature threshold interval, it indicates that the match fails, and the real-time temperature value is an abnormal temperature value, and the corresponding dehumidification operation instruction 2 is generated based on the positive abnormality of the real-time temperature value and transmitted to the control module.

[0022] As a further improvement of the present invention, the positioning module is used to set the location data of the external cabinet, and obtain the humidity prediction value of the location based on the location data and the corresponding networking module. The networking module is used to connect to the Internet to obtain the humidity prediction value of the location of the external cabinet, and preset humidity prediction thresholds of different levels, and select the maximum value to the minimum value of the influence to form a humidity prediction threshold interval.

[0038] In order to make the objects and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with embodiments; it should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] See also Figure 1-Figure 6As shown, an intelligent dehumidification system for power cabinets based on the Internet of Things comprises an outer cabinet 1, outer cabinet doors 101 are movably installed on both sides of the front end of the outer surface of the outer cabinet 1 through hinges, vents 102 are opened on the upper parts of both sides of the outer surface of the outer cabinet 1, and a discharge hole 103 is opened through the middle of the lower surface of the outer cabinet 1, an inner cabinet 2 is fixedly installed on the inner top surface of the outer cabinet 1, inner cabinet doors 201 are movably installed on both sides of the front end of the outer surface of the inner cabinet 2 through hinges, and a plurality of heat dissipation openings 202 are opened in the middle of both sides of the outer surface of the inner cabinet 2;

[0040] The inner cabinet 2 can be isolated from the outside world through the outer cabinet 1, and the heat dissipation port 202 can facilitate the normal heat dissipation of the inner cabinet 2 into the outer cabinet 1. At the same time, the vent 102 can facilitate the normal heat discharge from the outer cabinet 1 to the outside to complete the heat dissipation of the cabinet. The discharge hole 103 can facilitate the condensation and dehumidification operation of the internal moisture of the outer cabinet 1 and then discharge the condensation to the outside of the cabinet.

[0041] A movable plate 3 is movably mounted on the lower surface of the inner cabinet 2, and sealing blocks 301 are fixedly mounted on the upper parts of both sides of the outer surface of the movable plate 3. The sealing blocks 301 match the opening size of the vent 102, and a flow opening 302 is penetrated through the middle of the upper surface of the sealing block 301. Electric support rods 303 are fixedly mounted on the four corners of the lower surface of the movable plate 3.

[0042] The movable plate 3 can be driven to move up and down by the telescopic operation of the electric support rod 303, and the sealing block 301 can be driven to move by the lifting and lowering movement of the movable plate 3. When the movable plate 3 rises to the limit, the sealing block 301 can be driven to cover the vent 102, thereby sealing the vent 102 to prevent external moisture from entering the outer cabinet 1. When the movable plate 3 descends, the sealing block 301 and the vent 102 can be driven to separate from each other, thereby releasing the blockage of the vent 102 to ensure the normal operation of the vent 102. The flow port 302 can ensure the normal circulation of the airflow inside the outer cabinet 1 when the sealing block 301 blocks the vent 102.

[0043] A first dehumidification box 4 is fixedly installed in the middle of the lower surface of the movable plate 3, and a refrigeration pipe 401 is fixedly installed on the upper parts of both sides of the inner surface of the first dehumidification box 4. Openings are opened in the middle of both sides of the outer surface of the first dehumidification box 4. A micro air pump 402 is fixedly installed on the inner surface of the first dehumidification box 4 through the opening, and an extrusion frame 403 is fixedly installed on the lower part of the inner surface of the first dehumidification box 4.

[0044] The internal air of the outer cabinet 1 can be transmitted and introduced into the first dehumidification box 4 through the micro air pump 402, and the low-temperature refrigeration is performed by the refrigeration tube 401 to reduce the temperature inside the first dehumidification box 4. When the internal temperature of the first dehumidification box 4 is reduced, the internal air of the outer cabinet 1 enters the first dehumidification box 4, and condensation will occur under the action of the low-temperature environment, thereby reducing the moisture content in the air. At the same time, the condensation will remain in the first dehumidification box 4. The air with reduced moisture content will be re-discharged into the outer cabinet 1 under the action of the micro air pump 402, thereby increasing the dryness of the air inside the outer cabinet 1 and reducing the humidity. The adsorption sponge 406 can be squeezed by the squeezing frame 403.

[0045] A second dehumidification box 404 is fixedly installed in the middle of the inner bottom surface of the outer cabinet 1, a telescopic sleeve 405 is fixedly installed between the upper surface of the second dehumidification box 404 and the lower surface of the first dehumidification box 4, an adsorption sponge 406 is placed on the inner bottom surface of the second dehumidification box 404, and a discharge port 407 is opened in the middle of the lower surface of the second dehumidification box 404, and the discharge port 407 is aligned with the discharge hole 103;

[0046] The condensation left in the first dehumidifier box 4 can be collected by the second dehumidifier box 404, and the condensation can slide through the inner walls of the first dehumidifier box 4 and the second dehumidifier box 404 to the adsorption sponge 406 and be absorbed by it. Since the first dehumidifier box 4 is fixedly connected to the movable plate 3, the first dehumidifier box 4 can be simultaneously driven to be lifted and lowered by the electric support rod 303. The telescopic sleeve 405 can facilitate the first dehumidifier box 4 to maintain a closed connection with the second dehumidifier box 404 when the first dehumidifier box 4 is lifted and lowered. When the first dehumidifier box 4 moves downward with the movable plate 3, the extrusion frame 403 arranged inside it can be synchronously lowered to squeeze the adsorption sponge 406, so that the condensation adsorbed on the adsorption sponge 406 is squeezed out and discharged to the outside of the cabinet through the discharge port 407 and the discharge hole 103, so as to remove the condensation content in the adsorption sponge 406.

[0047] An intelligent controller 5 is fixedly installed at the front middle of the outer surface of the first dehumidification box 4;

[0048] The intelligent controller 5 includes a networking module, a positioning module, an early warning unit, a control module and a data processing unit;

[0050] The specific analysis is as follows: preset different levels of humidity prediction thresholds SD1, SD2, SD3..., and substitute them into the formula The humidity prediction threshold proportion values ​​∑1, ∑2, ∑3... are obtained, wherein δ1, δ2, δ3 represent the set proportional coefficient factors respectively, and the humidity prediction threshold intervals (-∑1, ∑1, +∑1), (-∑2, ∑2, +∑2), (-∑3, ∑3, +∑3)... are selected from the maximum to the minimum values ​​of the influence thereof. The higher the level of the humidity prediction threshold value, the higher the humidity outside the cabinet represented by it. The networking module is connected with the wireless signal of the Internet of Things through the networking module, and the networking module receives the humidity prediction value SD of the location of the external cabinet 1 of the Internet of Things in real time. The formula ∑=SD×δ is substituted to obtain the humidity prediction proportion value ∑, and the humidity prediction proportion value is substituted into the humidity prediction threshold interval for search and matching. The humidity level corresponding to the humidity prediction value is obtained according to the matching result and transmitted to the early warning unit.

[0051] The positioning module is used to set the location data of the outer cabinet 1, and obtain the humidity prediction value of the location based on the location data corresponding to the networking module;

[0052] The specific analysis is: the longitude and latitude coordinates of the location of the outer cabinet 1 are set through the positioning module, and the positioning is specifically set to the area that can be queried by the Internet of Things. Based on the networking module of the area, the humidity prediction value of the area is obtained in real time through the Internet of Things to obtain the humidity prediction value of the location of the outer cabinet 1.

[0053] The early warning unit starts the corresponding early warning instruction according to the received humidity forecast level, and transmits it to the control module to execute the corresponding early warning operation;

[0054] The specific analysis is as follows: substitute the humidity prediction ratio into the humidity prediction threshold interval for search and matching. If it successfully matches the humidity prediction threshold interval (-∑1, ∑1, +∑1), the corresponding humidity prediction level is level 1, indicating that the outside humidity is low. According to the level 1 humidity, the corresponding warning instruction is level 1. The warning operation corresponding to the level 1 warning instruction is:

[0055] 1S1, all mechanisms are in the normal closed state, and the outer cabinet 1 and the inner cabinet 2 can operate with normal ventilation and heat dissipation;

[0056] If the humidity prediction ratio successfully matches the humidity prediction threshold interval (-∑2, ∑2, +∑2) or above, the corresponding humidity prediction level is level 2, indicating that the outside humidity is high. The warning instruction corresponding to level 2 humidity is level 2, and the warning operation corresponding to the level 2 warning instruction is:

[0057] 2S1. Control the electric support rod 303 to extend until the limit, drive the movable plate 3 to rise, and control the sealing block 301 to cover the vent 102 to complete the sealing of the vent 102.

[0058] The data processing unit monitors, processes and analyzes the environmental factor data. The specific process is as follows:

[0059] Monitor the environmental factor data to obtain the real-time humidity, temperature and air flow velocity values, where the real-time humidity value is divided into the humidity value outside the cabinet and the humidity value inside the cabinet. Substitute the humidity value outside the cabinet and the humidity value inside the cabinet into the formula P1=|WS×β1-NS×β2| to obtain the humidity difference ratio P1, where WS and NS are the real-time values ​​of the humidity value outside the cabinet and the humidity value inside the cabinet, respectively, and β1 and β2 represent the set proportional coefficient factors respectively;

[0087] The specific analysis is as follows: the flow rate value of the airflow transmitted by the micro air pump 402 is monitored by the airflow monitoring module to determine the regulating power of the micro air pump 402, the airflow velocity threshold LS' is set, and the maximum value to the minimum value within the influence range is set to the flow rate threshold interval (-LS', LS', +LS'), and the airflow velocity value LS is monitored and collected by the airflow monitoring module, and matched with the flow rate threshold interval. If the match is successful, it indicates that the micro air pump 402 is in normal power operation. If And <-LS', it indicates that the micro air pump 402 is in low power operation. And when >+LS', it indicates that the micro air pump 402 is in high power operation.

[0088] The control module controls each actuator to perform corresponding operation based on the received dehumidification operation instructions one and two and the early warning instruction;

[0089] The specific analysis is: based on the early warning instruction, it is set as priority execution. Secondly, if the received dehumidification operation instruction one is any instruction content of S11-S14, and the dehumidification operation instruction two is S21, the operation of each actuator is controlled in combination with the dehumidification instructions one and two. At the same time, with the help of the networking module, an abnormal early warning signal of low temperature in the inner cabinet 2 is sent to the mobile terminal of the manager. If the received dehumidification operation instruction one is any instruction content of S11-S14, and the dehumidification operation instruction two is S22, the operation of each actuator is controlled in combination with the dehumidification instructions one and two.

[0090] When the present invention is in use, the intelligent controller 5 processes and analyzes the humidity environment inside and outside the outer cabinet 1 to obtain corresponding operation instructions, and controls the operation of each actuator based on the operation instructions. When the humidity environment outside the outer cabinet 1 is high, the electric support rod 303 is first controlled to extend and drive the movable plate 3 to move upward. When the movable plate 3 rises to the limit, it can drive the sealing block 301 to cover the vent 102, thereby blocking the vent 102 to prevent external moisture from entering the outer cabinet 1. After the vent 102 is blocked, the inner cabinet 2 can be isolated from the outside, and the control system is started at this time. The cold pipe 401 performs low-temperature refrigeration to lower the temperature in the first dehumidification box 4, and starts the micro air pump 402 to extract the internal air of the outer cabinet 1 and introduce it into the first dehumidification box 4. When the internal temperature of the first dehumidification box 4 is reduced, the internal air of the outer cabinet 1 enters the first dehumidification box 4, and condensation occurs under the action of the low-temperature environment, thereby reducing the moisture content in the air. At the same time, the condensation will remain in the first dehumidification box 4, and the air with reduced moisture content will be re-discharged into the outer cabinet 1 under the transportation of the micro air pump 402, thereby improving the dryness of the air inside the outer cabinet 1 and reducing the humidity.

[0091] Secondly, when the cooled and dehumidified air is discharged to the inside of the outer cabinet 1, it can enter the inner cabinet 2 through the heat dissipation port 202, and achieve the effect of cooling and dissipating the inside of the inner cabinet 2 under the action of the low-temperature air, so as to ensure that the inner cabinet 2 with the vent 102 in a closed state can dissipate heat and cool normally, and achieve the effect of dehumidifying the inside of the outer cabinet 1 through the circulation operation;

[0092] When the humidity outside the outer cabinet 1 is low, the electric support rod 303 can be controlled to retract and drive the movable plate 3 to move downward. When the movable plate 3 moves downward, the sealing block 301 and the vent 102 can be driven to separate from each other, thereby releasing the blockage of the vent 102 and ensuring the normal operation of the vent 102.

[0093] Secondly, the condensation left in the first dehumidification box 4 can be collected by the second dehumidification box 404, and the condensation can slide through the inner walls of the first dehumidification box 4 and the second dehumidification box 404 to the adsorption sponge 406 and be absorbed by it. When the movable plate 3 moves downward, it can drive the first dehumidification box 4 to descend synchronously. At this time, the extrusion frame 403 arranged inside the first dehumidification box 4 can descend synchronously to squeeze the adsorption sponge 406, so as to squeeze out the condensation adsorbed by the adsorption sponge 406 and discharge it to the outside of the cabinet through the discharge port 407 and the discharge hole 103, so as to remove the condensation content in the adsorption sponge 406, so as to facilitate the subsequent reuse of the adsorption sponge 406 in a humid state.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
