Referring to fig. 1 to 6, a first embodiment of the present invention provides a power cabinet based on intelligent monitoring. As shown in fig. 1, the power supply cabinet based on intelligent monitoring includes a cabinet 100, and a heat dissipation mechanism 200 disposed at the top of the cabinet 100. The cabinet body 100 is an external shell structure of the power supply cabinet based on intelligent monitoring, and the heat dissipation mechanism 200 is used for evacuating hot air inside the cabinet body 100 and has a function of preventing dust from entering.

Specifically, the cabinet 100 includes an outer casing 101 and an accommodating space M formed by the outer casing 101, a cover assembly 102 is disposed on a front surface of the outer casing 101, and the cover assembly 102 is an opening and closing door of the cabinet 100. One side edge of the cover assembly 102 is hinged to one side edge of the housing 101 and can be opened or closed by being turned over, and the other side edge is connected to the housing 101 through a locking mechanism S.

Further, the housing 101 includes a cabinet sidewall 101a, a top plate 101b disposed at the top of the cabinet sidewall 101a, and a bottom plate 101c disposed at the bottom of the cabinet sidewall 101 a. The side wall 101a, the top plate 101b and the bottom plate 101c of the cabinet can jointly enclose an open accommodating space M. In addition, still be fixed with layering piece 101d in the accommodation space M, layering piece 101d is the platelike structure body of level setting, and it can be divided accommodation space M into upper and lower two-layer, does benefit to the subregion of the internal line of cabinet and arranges. Preferably, the side wall 101a of the cabinet body can be further provided with a plurality of heat dissipation holes 101a-1, and the heat dissipation holes 101a-1 are through holes and can be used for evacuating hot air in the cabinet body from the side.

The heat dissipation mechanism 200 of the present invention includes a driving assembly 201, a first isolation assembly 202, and a second isolation assembly 203. The combined application of the first isolation component 202 and the second isolation component 203 enables the power cabinet to have ventilation, heat dissipation and dustproof functions, and the driving component 201 is used for controlling the external circulation or the closed state of the air inside the power cabinet.

Specifically, the first isolation assembly 202 includes a first heat sink 202a located at the top of the housing 101, and a first expansion block 202 b. The first heat dissipating opening 202a protrudes upward from the top plate 101b to form a first cylindrical wall 202f, and the lower end of the second isolation component 203 is connected to the first isolation component 202 through the first cylindrical wall 202 f. The main body of the first expansion block 202b is a vertically arranged cylindrical structural body, and passes through the first heat dissipation opening 202 a.

The first heat dissipation opening 202a has a first telescopic hole 202a-1 fitted to the first telescopic block 202b, and the first telescopic block 202b can slide up and down in the first telescopic hole 202 a-1. The first vent 202a-2 is further disposed on the outer side of the first telescopic hole 202a-1, the first vent 202a-2 can communicate the space inside the first heat sink 202a (i.e., inside the cabinet) to the space outside the first heat sink 202a, and when the first telescopic block 202b is disposed in the first telescopic hole 202a-1, the first vent 202a-2 is not blocked.

Because the first expansion block 202b passes through the first heat dissipation opening 202a, the upper end of the first expansion block 202b is located at the upper portion of the first expansion hole 202a-1, and the upper end thereof is further provided with a first limit ring 202 b-1. The outer diameter of the first limit ring 202b-1 is larger than the inner diameter of the first telescopic hole 202a-1, and a first elastic member 202c (the first elastic member 202c may be a spring and is sleeved on the first telescopic block 202b) is further disposed between the first limit ring 202b-1 and the top surface of the first heat sink 202a, so that the first elastic member 202c can jack up the first telescopic block 202b integrally with the first limit ring 202b-1 as an action point.

In addition, the lower end of the first telescopic block 202b is located at the lower part of the first telescopic hole 202a-1, and the lower end head of the first telescopic block is fixed with a sealing member 202d, and the sealing member 202d may be an end cap at the lower end of the first telescopic block 202b, so as to prevent the first telescopic block 202b from being "pulled" up by the first elastic member 202 c. Preferably, the first expansion block 202b is further sleeved with a first sealing ring 202e, and the first sealing ring 202e is sandwiched between the sealing element 202d and the lower surface of the first heat dissipation opening 202 a. Due to the first elastic member 202c, the first seal ring 202e can be pressed against the lower surface of the first heat radiation port 202a by the seal 202 d.

The invention sets the following steps: the first sealing ring 202e can completely cover the lower end of the first vent 202a-2, so that in a normal state, the first sealing ring 202e can block the first vent 202a-2, so that the space inside the power cabinet cannot be communicated with the outside through the first heat dissipation opening 202 a. On the contrary, if the upper end of the first telescopic block 202b is pressed by an external force to drive the sealing element 202d to move downward, the first sealing ring 202e is separated from the lower surface of the first heat dissipating port 202a, the first heat dissipating port 202a is opened, and the inside and the outside are communicated. Therefore, when the interior of the power cabinet needs heat dissipation, the space can be communicated, and when the interior of the power cabinet does not need the heat dissipation, the flow path can be blocked, so that dust is prevented from entering the power cabinet.

Based on the above, the pressing action of the external force on the first expansion block 202b is facilitated, and: dust enters the cabinet body in the process of communicating the first air vent 202a-2 for heat dissipation, and the problem can be solved through the second isolation assembly 203 and the driving assembly 201 together.

In the present invention, the second isolation member 203 includes a land 203a and a second elastic member 203 b. The connecting disc 203a comprises an outer edge piece 203a-1 and a second heat dissipation port 203a-2, wherein the outer edge piece 203a-1 is a ring-shaped annular body on the periphery of the connecting disc 203a and covers the upper surface of the top plate 101 b; the second heat release port 203a-2 is also an upper port position point for communicating with the gas flow path, as with the first heat release port 202 a.

Specifically, the second heat dissipation opening 203a-2 protrudes upward from the center of the outer edge member 203a-1 to form a second cylinder wall 203a-3 of the side surface, and the second elastic member 203b is sleeved on the periphery of the second cylinder wall 203a-3, and further, the second elastic member 203b can be a spring, the upper end of the spring abuts against the driving assembly 201, and the lower end of the spring abuts against the upper surface of the outer edge member 203 a-1. In addition, the lower end of the second cylinder wall 203a-3 is sleeved on the periphery of the first cylinder wall 202f to form sealing and fixing, meanwhile, the outer edge part 203a-1 covers the upper surface of the top plate 101b, a second sealing ring 203c is further arranged between the first cylinder wall and the top plate, and the second sealing ring 203c is sleeved on the periphery of the first cylinder wall 202f, so that the contact sealing effect between the outer edge part 203a-1 and the upper surface of the top plate 101b can be improved. The first sealing ring 202e and the second sealing ring 203c in the present invention are both annular structures for sealing, and may be made of rubber material or other metal material.

In the present invention, the driving assembly 201 includes a second expansion block 201a and a pressing plate 201b fixed to an upper end of the second expansion block 201a, and a pressing plate 201c is further provided at a lower side of the pressing plate 201 b. The main body of the second expansion block 201a is a vertically arranged cylindrical structure, and passes through the second heat dissipation opening 203 a-2.

Specifically, the upper end of the second expansion block 201a is located above the second heat dissipation opening 203a-2, and the periphery of the upper end of the second expansion block has a fixing ring groove 201a-1, the fixing ring groove 201a-1 is a ring of ring groove, and the centers of the pressing disc 201b and the pressing disc 201c respectively have a first fixing hole 201b-1 and a second fixing hole 201c-1 (both are round holes capable of meshing with the fixing ring groove 201a-1) which are respectively matched with the fixing ring groove 201a-1, so that the pressing disc 201b and the pressing disc 201c can be respectively fixed in the fixing ring groove 201a-1 through the first fixing hole 201b-1 and the second fixing hole 201c-1 in a stacking manner.

The lower end of the second expansion block 201a passes through the second heat dissipation opening 203a-2 downwards, and the second heat dissipation opening 203a-2 is provided with a second expansion hole 203a-21 matched with the second expansion block 201a, so that the second expansion block 201a can slide up and down in the second expansion hole 203 a-21. In addition, the outer side of the second telescopic hole 203a-21 is provided with a second ventilation hole 203a-22, so that the space inside the second heat radiation port 203a-2 can be communicated with the external space. From the above, it is apparent that: the second elastic member 203b is located between the pressing plate 201c and the outer edge member 203a-1 and lifts the entire driving unit 201 upward. Correspondingly, the lower end head of the second telescopic block 201a is provided with a second limiting ring 201a-2, and the outer diameter of the second limiting ring 201a-2 is larger than the inner diameter of the second telescopic hole 203a-21, so that the second telescopic block 201a is not pulled up integrally under the action of the second elastic part 203 b.

The butt-joint block 201a-3 is fixed below the second limit ring 201a-2, and the butt-joint block 201a-3 may be a cylindrical structure, which is located right above the first limit ring 202b-1 and has a certain distance from the top surface of the first expansion block 202b in a normal state. When the pressing plate 201b is pressed downwards by external force, the pressing plate 201b drives the second telescopic block 201a to move downwards, and meanwhile, the butt-joint block 201a-3 at the lower end of the second telescopic block is in contact with the first telescopic block 202b and is pressed downwards, so that hot air flow in the power supply cabinet can enter the second heat dissipation opening 203a-2 from the first air vent 202a-2 in sequence and then flow into the external space from the second heat dissipation opening 203a-2 through the second air vent 203 a-22. In this process, due to the double covering effect of the pressing plate 201b and the second heat dissipation opening 203a-2 and the circuitous flow path thereof, external dust hardly enters the interior of the first heat dissipation opening 202a of the innermost layer (i.e., the interior of the power cabinet). It should be noted that: the downward pressure of the pressing plate 201b can be achieved by placing an object on top of it, although the pressing manner can be varied.

Referring to fig. 7 to 17, a second embodiment of the present invention is different from the previous embodiment in that: the power cabinet based on intelligent monitoring of the invention further includes a locking mechanism S, which is fixed on the outer side wall of the cabinet body 100 and is used for locking the cover assembly 102 and the housing 101 temporarily or permanently, that is: the locking mechanism S has both a temporary locking/unlocking function for the closing unit 102 and a long-term locking function for the closing unit 102.

Wherein the first connecting edge 102a is hinged with one side of the opening of the casing 101, and the second connecting edge 102b can be connected with the other side (opposite to the hinged side) of the opening of the casing 101 by the locking mechanism S to form a lock.

As shown in fig. 8, the locking mechanism S includes a first locking portion 300 and a second locking portion 400, the first locking portion 300 is fixed on the outer side surface corresponding to the second connecting edge 102b, and the lower end surface thereof is provided with a connecting assembly 301, and the connecting assembly 301 is in a downwardly extending hook-shaped structure; the second locking portion 400 is fixed on the housing 101 at a position corresponding to the first locking portion 300, and includes an opening/closing component 401, a locking component 402, and a driving component 403, wherein the opening/closing component 401 and the locking component 402 are sleeved on the periphery of the driving component 403, and the driving component 403 can drive the opening/closing component 401 or the locking component 402 to rotate. It should be noted that: for the purpose of structural description, the following description will refer to the relative spatial positions of the components in the locking mechanism S, and will be based on the positions shown in fig. 8-17.

In the invention, when the cover assembly 102 is turned over and fastened to the housing 101, the connecting assembly 301 can be just embedded into the second locking part 400 and can cooperate with the opening and closing assembly 401, so that the temporary locking function is achieved; and the driving component 403 acts on the locking component 402 and cooperates with the connecting component 301, so that the permanent locking function is achieved.

Therefore, as can be seen from the above description, when the protruding part 403a-1 of the first driving part 403a is inserted into the first notch 401b-3, the first rotating ring 401b-1 can be driven to rotate by rotating the first driving part 403a, and the first rotating ring 401b-1 can pull the guide block 401a-2 to slide downward in the second guide part 401a through the transmission of the connecting rod 401 b-2.

The first barb 401c is disposed on one side of the second guide 401a through the first limiting frame 401d, wherein the first barb 401c is a long strip-shaped hook-shaped structure, and the hook head of the first barb 401c is located at the upper end of the first barb 401c and can be matched with the connecting component 301; the first limiting frame 401d is used for mounting the first barb 401c and limiting the rotation amplitude of the first barb 401 c. A middle section of the first barb 401c is hinged to the first stopper 401d, and the first barb 401c is divided into a first region 401c-1 at the upper end and a second region 401c-2 at the lower end by a hinge node (where the first region 401c-1 and the second region 401c-2 are both made of a magnetically attractable material such as iron or iron-nickel alloy).

The top of the guide block 401a-2 is provided with a magnetic member 401a-5 corresponding to the first barb 401c, and the magnetic member 401a-5 can generate magnetic attraction (here, the magnetic member 401a-5 adopts a magnet) to the first region 401c-1 or the second region 401c-2, and cause the first barb 401c to rotate correspondingly, as follows:

since the guide block 401a-2 can move vertically up and down on one side of the first barb 401c, the magnetic member 401a-5 attracts the first barb 401c to rotate counterclockwise with respect to the first barb 401c when it is located at the position corresponding to the first region 401 c-1; when the first barb 401c is located at the position corresponding to the second zone 401c-2, the first barb 401c is attracted to rotate clockwise.

In the present invention, the initial state (temporarily locked state) of the opening/closing unit 401 is: the first rotating ring 401b-1 and the connecting rod 401b-2 are both vertical, and the magnetic member 401a-5 is located at the highest point and just corresponding to the first region 401c-1, so that the first barb 401c is attracted to a stable state and is engaged with the connecting component 301 to form a temporary lock.

The temporarily unlocked state of the opening and closing assembly 401 is: the rotating handle 403b-2 is operated to drive the first driving piece 403a to rotate, so that linkage can be generated, the guide block 401a-2 is pulled to slide downwards, until the magnetic piece 401a-5 slides to the position corresponding to the second area 401c-2, the first barb 401c rotates clockwise, the hook head is separated from the connecting component 301, and temporary unlocking is formed. At this time, when the rotation knob 403b-2 is released, the guide block 401a-2 returns to the original state by the resilient force of the first elastic member 401a-3, and remains in the temporarily locked state.

Therefore, summarizing the above two implementation processes, it can be seen that the locking and unlocking process can be implemented only by twisting the rotating handle 403 b-2. Preferably, since the outer edges of the hook heads of the connecting component 301 and the first barbs 401c are smooth curved surfaces, when the cover component 102 is turned over and fastened to the housing 101, the connecting component 301 can be smoothly fastened down along the top curved surface of the first barbs 401c and form a lock with the top curved surface.

Referring to fig. 9, 13-17, the locking assembly 402 can lock the closure assembly 102 for an extended period of time. In the present invention, the locking assembly 402 includes a second rotating ring 402a sleeved on the outer sidewall of the first driving member 403a, a second inverted hook 402b fixed on the second rotating ring 402a, and a limiting piece 402c embedded in the second rotating ring 402 a. The second rotating ring 402a has a structure similar to that of the first rotating ring 401b-1, the main body thereof is a ring-shaped structure, and the inner sidewall thereof has a second notch 402a-1 matching with the protruding member 403a-1, and the second notch 402a-1 has the same structural form as the first notch 401 b-3.

The second inverted hook 402b has a lower end fixed to the second rotating ring 402a and an upper end capable of engaging and locking with the first locking portion 300. Accordingly, the bottom surface of the first locking portion 300 has a locking channel 302 that matches the configuration, contour of the second barb 402 b. When the hook head at the upper end of the second barb 402b is inserted into the locking channel 302, the permanent locking between the cover assembly 102 and the casing 101 can be performed.

A complementary limiting piece 402c is embedded in the ring of the second rotating ring 402a, and the limiting piece 402c is used for limiting the rotation of the second rotating ring 402a (and the second barb 402 b). The stopper piece 402c has a projection 402c-1 on the outer side thereof to be fitted into the second notch 402a-1, so that the stopper piece 402c is rotated or stopped in conformity with the second rotating ring 402a when it is positioned in the ring of the second rotating ring 402 a. In addition, a limit through hole 402c-2 (the main structure of the limit through hole 402c-2 is a through hole which is in clearance fit with the outer side wall of the guide 403c) is formed in the center of the limit piece 402c and is matched with the guide 403c, that is, the guide 403c passes through the limit through hole 402c-2 of the limit piece 402 c. Furthermore, the inner side wall of the limiting penetration hole 402c-2 is provided with a limiting strip 402c-3 along the longitudinal direction of the guide piece 403c, the limiting strip 402c-3 is a strip-shaped protrusion and is provided with a pair of mutually opposite limiting strips, and the guide piece 403c is provided with a limiting groove 403c-1 matched with the limiting strip 402 c-3. Therefore, after the stopper rib 402c-3 of the stopper piece 402c is fitted into the stopper groove 403c-1, it can be linearly slid in the longitudinal direction of the guide 403c, but cannot be relatively rotated. Since the stopper piece 402c is fitted into the ring of the second rotating ring 402a, the second rotating ring 402a cannot rotate.

In the present invention, it is noted that: in the initial state, the stopper piece 402c is integrally inserted into the ring of the second rotating ring 402a, and simultaneously, the inner end of the first driving member 403a is also inserted into the ring of the second rotating ring 402a, and the outer end surface of the stopper piece 402c contacts with the inner end surface of the first driving member 403a (both of which are located in the ring of the second rotating ring 402 a), so that the stopper piece 402c can be extruded out of the ring of the second rotating ring 402a by pushing the first driving member 403a by external force. In addition, the inner side of the limiting piece 402c is further provided with a second elastic member 402d (the second elastic member 402d can be a spring), the second elastic member 402d is sleeved on the guiding member 403c and abuts against the inner side surface of the limiting piece 402c, so as to abut the limiting piece 402c against the ring of the second rotating ring 402a, and prevent the situation that the limiting piece 402c is extruded out of the ring by pushing the first driving member 403a unintentionally by external errors. Correspondingly, the inner side surface of the limiting piece 402c is further provided with a plurality of limiting blocks 402c-4, and the limiting blocks 402c-4 are uniformly distributed on the outer edge of the circumference of the limiting piece 402c and used for preventing the limiting piece 402c from being extruded in the opposite direction due to the elastic force of the second elastic piece 402 d.

As described above, the stopper piece 402c can only slide within the length of the stopper groove 403c-1, and the sliding range is limited to the inside of the second rotating ring 402 a. In the invention, the outer side surface of the second barb 402b is connected with the second limiting frame 402e through a third elastic member 402e-1 (the third elastic member 402e-1 can adopt a spring), wherein the second limiting frame 402e is used for installing the third elastic member 402e-1, one end of the third elastic member 402e-1 is fixed on the second limiting frame 402e, and the other end abuts against the outer side surface of the second barb 402b to form elastic potential energy.

Thus, to summarize, the initial state (unlocked state) of the locking component 402 is: the stopper 402c is located in the second rotating ring 402a, and the second rotating ring 402a cannot rotate, so the second barb 402b cannot be inserted into the locking channel 302 for locking. In this state, the above-described temporary locking and unlocking process can be achieved by simply twisting the rotating knob 403 b-2.

The deadlocked state of the locking assembly 402 is: the first driving member 403a is pushed (pushing force is greater than the elastic force of the second elastic member 402 d), so that the inner end of the first driving member 403a pushes the stopper piece 402c out of the second rotating ring 402 a. Because there is no rotation restriction of the limiting piece 402c to the second rotating ring 402a (the limiting piece 402c cannot rotate all the time, but can only slide), the second barb 402b rotates clockwise along with the second rotating ring 402a under the elastic force of the third elastic member 402e-1 until the hook head of the second barb 402b is completely inserted into the locking channel 302, so as to form a locking.

The process of the locking component 402 removing the deadlocked state is: pushing the first driving member 403a inward until advancement is no longer possible, at which point the male member 403a-1 on the first driving member 403a is misaligned with the second notch 402a-1 of the second rotating ring 402a, thereby rotating the first driving member 403a until the male member 403a-1 is in spatial alignment with the second notch 402a-1 and advancing the embedment; then, the first driving member 403a is rotated reversely to drive the second rotating ring 402a to rotate reversely until the second notch 402a-1 of the second rotating ring 402a is aligned with the protrusion 402c-1 of the limiting piece 402c, and at this time, the limiting piece 402c pushes the limiting piece 402c into the ring of the second rotating ring 402a under the action of the second elastic member 402d, so as to restore to the initial state of the locking assembly 402, and the locked state is released.

Preferably, in the present invention, it is also possible to set: the second notch 402a-1 of the second rotating ring 402a is just aligned with the protruding part 403a-1 in the above-mentioned locking state (accordingly, the initial state of the second notch 402a-1 and the protrusion 402c-1 is a position rotated counterclockwise by a corresponding angle), and therefore, the procedure of releasing the locking state in this preferred case is as follows: the first driving member 403a is pushed to be embedded into the second rotating ring 402a, and then the second rotating ring rotates counterclockwise by a corresponding angle until the first driving member faces the limiting piece 402 c.

In the present invention, the second locking portion 400 further includes a lock housing 404, and the first limiting frame 401d and the second limiting frame 402c are fixed on an inner side wall of the lock housing 404. Additionally, the inner end of the guide 403c is secured to the end cap 403d, which in turn is secured to the inside surface of the lock body housing 404. The outer end of the second driving member 403b in the present invention extends through the lock body housing 404 and has a rotating handle 403b-2 secured to its end. In addition, the outer end of the lock body housing 404 is respectively provided with a first through hole 404a corresponding to the connecting component 301 and a first through hole 404b corresponding to the second inverse hook 402 b. The outer side of the lock body housing 404 is also covered with an outer cover 404c, and the periphery of the outer cover 404c is fixed to the edge of the lock body housing 404 by screws.

Referring to fig. 18 and 19, a third embodiment of the present invention is different from any of the above embodiments in that: the power cabinet based on intelligent monitoring further comprises an intelligent device A which is arranged inside the power cabinet based on intelligent monitoring and used for detecting the influence of various environmental factors (such as humidity, temperature and pressure … …) inside the power cabinet based on intelligent monitoring on the electronic products and the electrical equipment in the cabinet body in real time.

The intelligent device A comprises an induction unit A-100, a processing unit A-200 and a control unit, wherein the induction unit A-100 can induce and collect the environmental factors in the accommodating space M and convert the change of the environmental factors into data information to be transmitted to the processing unit A-200; the processing unit A-200 is connected with the sensing unit A-100, the sensing unit A-100 presets a corresponding threshold value for environmental factors, and after receiving the data information from the sensing unit A-100, the sensing unit A-100 compares the data information with the threshold value corresponding to the data information to determine whether the data information exceeds the corresponding threshold value; the indicating unit A-300 is connected with the processing unit A-200, and the indicating unit A-300 can make different feedbacks according to different comparison results of the processing unit A-200 between the data information and the corresponding threshold value; and the energy supply unit A-400 is simultaneously connected with each unit in the intelligent device A and supplies electric energy required by the work for each unit.

Specifically, the sensing unit a-100 may be directly implemented by using a sensor, which can directly detect and collect external environmental factors, such as humidity, temperature, etc., and convert the external environmental factors into data information to be transmitted to the processing unit a-200. The "data information" here is the electrical signal into which the sensing unit a-100 converts the environmental factors. In actual life, the influence of humidity and temperature on electronic products and electrical equipment is the largest, and particularly the service life of the electronic products and the electrical equipment is seriously reduced due to the increase of the humidity, so that the sensing unit A-100 in the invention can be respectively provided with a first sensing module A-101 and a second sensing module A-102 aiming at the humidity and the temperature of the environment, wherein the first sensing module A-101 is a humidity sensor and can detect the humidity of the environment in the accommodating space M and convert the humidity into an electric signal to be transmitted to the processing unit A-200; the second sensing module a-102 is a temperature sensor, which can detect the temperature of the environment in the accommodating space M, convert the temperature into an electrical signal, and transmit the electrical signal to the processing unit a-200.

But it should be noted that: according to the actual requirements, only one sensor can be arranged for one environmental factor, and a plurality of sensors can be arranged at the same time, and are not limited to humidity and temperature.

The processing unit A-200 is a CPU (Central processing Unit), which can adopt a microchip, the sensing unit A-100 can be connected with the processing unit A-200 through a data interface and a lead, and the processing unit A-200 is mainly used for receiving various data information from the sensing unit A-100 and comprehensively processing the obtained data information. The "integrated processing" herein includes the following processes:

the processing unit a-200 sets a corresponding threshold value in advance for an environmental factor, for example, a humidity threshold value and a temperature threshold value are set for humidity and temperature respectively, and the values of the two are early warning values which can generate obvious loss on electronic products and electrical equipment respectively. After the processing unit A-200 receives the data information from the first sensing module A-101 or the second sensing module A-102, the data information is compared with the corresponding threshold (for example, the data information from the first sensing module A-101 is compared with the humidity threshold, and the data information from the second sensing module A-102 is compared with the temperature threshold), and the instruction unit A-300 is instructed to perform different feedback performances according to different comparison results.

The indication unit a-300 of the present invention may adopt an indication lamp, which is connected with the processing unit a-200 and can receive the instruction of the processing unit a-200 to present different colors. In this embodiment, a first indicator light a-301 and a second indicator light a-302 may be respectively disposed for the first sensing module a-101 and the second sensing module a-102. Taking the first sensing module a-101 as an example, the processing unit a-200 may instruct the first indicator light a-301 to display green when the data information is lower than the humidity threshold, and the processing unit a-200 may instruct the first indicator light a-301 to display red when the data information is equal to or higher than the humidity threshold. Therefore, according to different colors, a user can know the change condition of the environmental humidity in real time and make corresponding security measures when necessary. The second sensing module A-102 works in the same manner, and is not described herein.

The power supply unit a-400 is a battery for supplying power to the respective unit devices on the smart device, and thus, the power supply unit a-400 is integrally connected with the sensing unit a-100, the processing unit a-200 and the indication unit a-300 through a circuit board at the same time.

Furthermore, the intelligent device a of the present invention may further include a remote transmission unit a-500, which is used for connecting with a Mobile Terminal (MT), providing and feeding back the environment condition inside the power cabinet based on intelligent monitoring and the dynamic condition of the early warning to the user in real time. The mobile terminal is a mobile phone or a computer with an APP, and the APP is software which takes the mobile terminal as a carrier and can receive a data signal sent by the remote transmission unit a-500. The remote transmission unit A-500 in the invention can adopt a wireless transmission module which is connected with the processing unit A-200 through an integrated circuit and can also carry out wireless connection and information transmission with the mobile terminal, and the comparison result of the processing unit A-200 and the instruction information of the indication unit A-300 are sent to the mobile terminal in real time for a client to know the situation.

Furthermore, each unit and module inside the intelligent device a according to the present invention may be integrated in an integrated circuit manner, and the whole intelligent device a is fixed inside the power cabinet based on intelligent monitoring, which may be fixed on the inner side wall of the housing 101 or on the inner side surface of the covering assembly 102. The fixing mode can be as follows: the fixed point is reserved or the intelligent device A is wrapped by a plastic shell directly when the shell 101 (or the cover assembly 102) is molded, and the plastic shell is fixed in the power cabinet based on intelligent monitoring in a magic tape mode, so that the power cabinet is convenient to disassemble and repair or maintain. Such as: when the smart device a is secured to the inside surface of the closure assembly 102, the indicator units a-300 need to be passed through the closure assembly 102 from the inside and out of the outside thereof for direct viewing by the human eye from the outside.

It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
