[0027] The present invention is further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 In this embodiment, the intelligent power supply and distribution integrated system 400 is applied to the multifunctional intelligent device 200 to automatically monitor and intelligently control the multifunctional intelligent device 200.

[0029] It can be understood that the intelligent power supply and distribution integrated system 400 can also be applied to many scenarios such as urban multifunctional intelligent poles, smart lamp poles, transportation industry electromechanical equipment, urban security systems, urban meteorological and environmental monitoring systems, outdoor electronic equipment in tourist scenic spots, mobile communication base stations, smart home systems, and urban outdoor publicity equipment, and can be installed according to actual needs. The present invention plays a technical guarantee role in the refined management of related fields and the normal operation of urban and rural road traffic electrical and electronic facilities and the intensive utilization of resources.

[0030] In this embodiment, the smart power and distribution integrated system 400 is a compact and smart power & distributor system (CSPDS). The smart power and distribution integrated system 400 includes a smart power and distribution integrated device 100 and an external device 300.

The multifunctional intelligent device 200 includes a cylindrical warehouse body 201, a warehouse door (not shown) installed in the warehouse body 201, and the intelligent power supply and power distribution integrated device 100 accommodated in the warehouse body 201. The intelligent power supply and power distribution integrated device 100 has a cylindrical structure as a whole (refer to Figure 2 ), the intelligent power supply and power distribution integrated device 100 is installed vertically in the bin 201 of the cylindrical multifunctional intelligent device 200. It can be understood that the intelligent power supply and power distribution integrated device 100 is installed horizontally in the bin 201 of the cylindrical multifunctional intelligent device 200. The shape of the multifunctional intelligent device 200 can also be set to different shapes according to actual needs.

[0033] Since the intelligent power supply and power distribution integrated device 100 is directly installed inside the multifunctional intelligent device 200, damage to the intelligent power supply and power distribution integrated device 100 is prevented. In addition, due to the cylindrical structure of the intelligent power supply and power distribution integrated device 100, the internal space of the multifunctional intelligent device 200 is effectively utilized and the structure is compact.

[0034] Please refer to Figures 1 to 4 The intelligent power supply and power distribution integrated device 100 includes a housing 10, a mounting plate 30, an intelligent monitoring module 64, an intelligent reset circuit breaker module 61, a miniature circuit breaker module 62, an intelligent power supply module 40, and a control circuit board 50. The intelligent power supply and power distribution integrated device 100 is also selectively provided with a lightning protection module 63, an intelligent meter module 65, and a maintenance socket 67, which can also be omitted.

[0035] Please refer to Figures 1 to 7, a mounting plate 30 is installed inside the housing 10, and the mounting plate 30 is in a plate shape. It can be understood that the structure of the mounting plate 30 can also be other mounting part structures. The back of the mounting plate 30 is sequentially mounted with a control circuit board 50, an intelligent monitoring module 64, and an intelligent meter module 65, and the front of the mounting plate 20 is sequentially mounted with an intelligent reset circuit breaker module 61, a miniature circuit breaker module 62, a lightning protection module 63, and a maintenance socket 67.

[0036] It can be understood that the smart meter module 65, the lightning protection module 63 and the maintenance socket 67 can be installed selectively or omitted.

[0037] Please refer to Figure 2 as well as Figure 6 The housing 10 includes a hollow housing 11 and a second cover plate 12 and a first cover plate 13 disposed at both ends of the housing 11. The housing 11, the second cover plate 12 and the first cover plate 13 form a receiving cavity 14. In the present embodiment, the outer contour of the housing 11 is an elongated cylindrical shape, so that the outer contour of the housing 10 as a whole is an elongated structure. The housing 11 is made of a heat dissipation material, and further, the housing 11 is made of an aluminum alloy material. It can be understood that the housing 11 can also be made of other metal materials as long as it has a heat dissipation effect.

[0038] The outer side of the side wall of the housing 11 protrudes and extends to form a plurality of heat dissipation portions 111, which are serrated and protrude and extend outward from the outer periphery of the outer surface of the side wall of the housing 11, and are used to dissipate the heat in the receiving cavity 14. In this embodiment, each heat dissipation portion 111 is composed of a plurality of heat dissipation fins arranged at intervals, that is, the heat dissipation fins protrude and extend outward from the outer surface of the side wall of the housing 11, thereby forming a plurality of heat dissipation fins in a serrated shape. It is understood that the plurality of heat dissipation portions 111 can also be formed by being recessed from the outer side wall of the housing 11.

[0039] Please refer to Figure 3 The shell 11 includes a first side wall 112, a second side wall 113, a third side wall 114 and a fourth side wall 115, wherein the first side wall 112 and the second side wall 113 are arranged opposite to each other, and the third side wall 114 and the fourth side wall 115 are arranged opposite to each other.

[0040] A first flat portion 1121 and a second flat portion 1122 are provided on both sides of the first side wall 112 near the third side wall 114 and the fourth side wall 115, and the first flat portion 1121 and the second flat portion 1122 are separated by a first protruding portion 1123. A heat dissipation portion 111 composed of a plurality of heat dissipation fins is provided protruding outwardly from the outer sides of the first flat portion 1121 and the second flat portion 1122. Furthermore, the plurality of heat dissipation fins of the first flat portion 1121 and the second flat portion 1122 decrease in height as they are away from the first protruding portion 1123.

[0041] The third side wall 114 is provided with a third flat portion 1141 and a fourth flat portion 1142, and the third flat portion 1141 and the fourth flat portion 1142 are separated by a second protruding portion 1143. A heat dissipation portion 111 consisting of a plurality of heat dissipation fins is protruded outwardly from the outer sides of the third flat portion 1141 and the fourth flat portion 1142. Furthermore, the plurality of heat dissipation fins on the third flat portion 1141 and the fourth flat portion 1142 decrease in height as they are away from the second protruding portion 1143.

[0042] The fourth side wall 115 is provided with a fifth flat portion 1151 and a sixth flat portion 1152, and the fifth flat portion 1151 and the sixth flat portion 1152 are separated by a third protrusion 1153, and the third protrusion 1153 is arranged opposite to the second protrusion 1143. The heat dissipation portion 111 composed of a plurality of heat dissipation fins is protruded outwardly from the outer sides of the fifth flat portion 1151 and the sixth flat portion 1152. Further, the height of the plurality of heat dissipation fins of the fifth flat portion 1151 and the sixth flat portion 1152 decreases as they are away from the third protrusion 1153.

[0043] In this way, the cross-sectional shape of the housing 11 can be ensured to be roughly circular while the heat dissipation portion 111 is provided. In this way, the intelligent power supply and power distribution integrated device 100 is in an elongated cylindrical shape as a whole, which is convenient for being accommodated in a lamp pole. Of course, in other embodiments, the height of the heat dissipation portion 111 and the number of heat dissipation fins can be adjusted according to needs, which is not limited here.

[0044] It can be understood that by arranging multiple heat dissipation parts 111 at intervals on the outer periphery of the shell 11, the heat inside the shell 11 can be effectively and timely dissipated to avoid the situation where the temperature inside the shell 11 is too high, thereby avoiding affecting the internal devices.

[0045] In this embodiment, the intelligent power module 40 is arranged on the inner side of the first side wall 112. In this way, a heat dissipation portion 111 is provided around the intelligent power module 40 facing the shell 11, which can effectively and quickly dissipate heat, thereby effectively avoiding the temperature at the intelligent power module 40 being too high.

[0046] Further, please refer to Figure 2 and Figure 6 The second side wall 113 is provided with a window 117 , and a portion of the maintenance socket 67 , the lightning protection module 63 , the miniature circuit breaker module 62 , and the intelligent reset circuit breaker module 61 are exposed from the window 117 .

[0047] In the present embodiment, the second side wall 113 is provided with a first window 1171 and a second window 1172, wherein the first window 1171 is used to accommodate the maintenance socket 67. In the present embodiment, the maintenance socket 67 is directly installed in the first window 1171 of the shell 11. In the present embodiment, the maintenance socket 67 is installed in the first window 1171 of the shell 11 in a suspended manner.

[0048] The second window 1172 is used to expose at least a portion of the lightning protection module 63, the miniature circuit breaker module 62, and the intelligent reset circuit breaker module 61. The end of the second window 1172 away from the first window 1171 is open, that is, the second window 1172 is roughly "U"-shaped to facilitate assembly.

[0049] For further information, please refer to Figure 2 and Figure 3 , Figure 6 , a window cover 118 is also provided on the second side wall 113 of the housing 11, and the window cover 118 is provided on the housing 11 and covers the window 117. The window cover 118 includes a base 119 and a window cover 120, and the window cover 120 is rotatably provided on the base 119, and a connecting portion 1191 is provided on one long side of the base 119, and the connecting portion 1191 is arranged toward the window cover 120, and the window cover 120 is provided with a matching portion 1201 at a corresponding position, and the matching portion 1201 is rotatably provided on the connecting portion 1191, so that the window cover 120 is rotatably provided on the base 119. When the window cover 120 is rotated to the open state, the lightning protection module 63, the intelligent reset circuit breaker module 61, the miniature circuit breaker module 62, and the maintenance socket 67 can be operated.

[0050] Furthermore, a groove 1192 is formed on one side of the base 119 for accommodating the window cover 120 , and a sealing ring 1193 is accommodated in the groove 1192 . The sealing ring 1193 is made of silicone material, but can also be made of other materials, which is not limited here.

[0051] It can be understood that by providing a sealing ring 1193 in the groove 1192, when the window cover 120 is covered on the base 119, it can better achieve the effects of waterproofing, dustproofing, and smoke particle prevention.

[0052] Furthermore, a buckle 1194 is further provided on the other long side of the base 119, and correspondingly, a locking portion 122 is provided on the window cover 120, and the locking portion 122 is locked in the buckle 1194. In this way, after the window cover 120 is covered on the base 119, the user can lock it as needed to improve the safety of electricity use.

[0053] In addition, in this embodiment, the buckle 1194 is integrally formed with the base 119, so that it has high strength and prevents loosening, and effectively improves the waterproof, dustproof and smoke particle proof performance.

[0054] Furthermore, a plurality of protrusions 123 are provided at intervals around the outer periphery of the window cover 120 to prevent surface scratches on flat objects and effectively improve the anti-extrusion capability.

[0055] In addition, the window cover 120 can be made of a transparent material, so that the staff can observe the working status of the lightning protection module 63, the intelligent reset circuit breaker module 61, and the miniature circuit breaker module 62 through the window cover 120. Of course, the window cover 120 can also be made of a non-transparent material, which is not limited here.

[0056] It can be understood that the base 119 is fixed to the housing 11 via a fixing member (not shown), and the fixing member can be a screw or the like, which is not limited here.

[0057] In addition, the base 119 is disposed on the housing 11 via the seal 1195 to provide waterproof, dustproof, and smoke particle-proof effects.

[0058] Of course, in other embodiments, the window cover 120 may be directly disposed on the housing 11 via the seal 1195 , that is, the base 119 may be omitted, as long as the sealing of the receiving chamber 14 can be ensured.

[0059] Furthermore, the second cover plate 12 is sealed and connected to the housing 11 . The intelligent power supply and power distribution integrated device 100 further includes a first cable 121 . The first cable 121 is arranged to penetrate the second cover plate 12 . The first cable 121 is electrically connected to an external load for power supply.

[0060] In this embodiment, the second cover plate 12 is made of a soft rubber material and can be a puncture plate. Thus, when the first cable 1211 passes through the second cover plate 12, a good sealing effect can be achieved without using a sealing member.

[0061] Furthermore, the intelligent power supply and power distribution integrated device 100 further includes a second cable 131, which is arranged through the first cover plate 13, and the second cable 131 is electrically connected to the external power supply device. Furthermore, the second cable 131 and the first cover plate 13 are sealed by a seal such as a gland. Considering that the intelligent reset circuit breaker module 61 needs to be electrically connected to the second cable 131, it is preferred to arrange the intelligent reset circuit breaker module 61 on a side close to the first cover plate 13.

[0062] In addition, the first cover plate 13 and the housing 11 are sealed by a sealing gasket 134 to achieve waterproof and dustproof effects. It can be understood that the intelligent power supply and power distribution integrated device 100 of this embodiment has a protection level of not less than IP65 and can even reach IP67 through the structure of the housing 11, the second cover plate 12 and the first cover plate 13.

[0063] It is understandable that under certain environmental conditions, moisture accumulation in the cable can cause failures in the electrical module and the power electronic module. Therefore, when the electronic device is immersed in water, sand or a small space, good electrical connection plays a vital role in ensuring the reliability of the use of the intelligent power supply and distribution integrated device. In this case, a special anti-condensation connector can be used, because it has a special moisture-proof layer that can effectively prevent moisture in the cable from entering the connector and continuing to invade the receiving cavity, thereby reliably avoiding short circuits, leakage, circuit corrosion, etc. in the internal electrical module and the power electronic module under extreme conditions.

[0064] Further, please refer to Figure 4 and Figure 6 A plurality of exhaust ports 130 are disposed on the first cover plate 13 , and the heat dissipation fan 20 is disposed in the receiving cavity 14 and corresponding to the exhaust ports 130 to discharge the heat in the receiving cavity 14 to the through hole 120 , so as to effectively prevent the temperature in the receiving cavity 14 from being too high.

[0065] It can be understood that during normal operation of the cooling fan 20, the cooling fan 20 plays a major role in heat dissipation, while the multiple heat dissipation parts 111 on the housing 11 play an auxiliary role in heat dissipation. When the cooling fan 20 stops running due to a fault or runs slowly, resulting in poor heat dissipation, the multiple heat dissipation parts 111 on the housing 11 play a major role in heat dissipation, so that the heat dissipation of the intelligent power supply and power distribution integrated device 100 can be maintained in real time.

[0066] In addition, an exhaust port 130 is provided on the first cover plate 13. When the electronic device 100 is placed upright, since the exhaust port 130 is located at the bottom, even if there is water on the upper part and the side, the water will not enter the accommodating cavity 14 through the exhaust port 130, thereby effectively avoiding affecting the internal intelligent monitoring module 64, the intelligent reset circuit breaker module 61, the miniature circuit breaker module 62, the intelligent power supply module 40, the control circuit board 50, the lightning protection module 63, and the intelligent meter module 65.

[0067] Please refer to Figure 3 , Figure 5 as well as Figure 6The mounting plate 30 includes a plate-shaped body 31 and a clamping member 32, and the clamping member 32 is disposed on the surfaces of both sides of the body 31. The clamping member 32 is formed on the body 31 by an integral molding method, and can also be fixed to the body 31 by a fixing member, which is not limited here.

[0068] The clamping member 32 is in an inverted "L" shape, and is used to clamp the intelligent monitoring module 64, the intelligent reset circuit breaker module 61, the miniature circuit breaker module 62, the lightning protection module 63, the intelligent meter module 65, and the maintenance socket 67, and to fix and install the control circuit board 50. Of course, in other embodiments, the clamping member 32 can also be other structures, which are not limited here.

[0069] Please refer to Figure 5 as well as Figure 7 , the intelligent reset circuit breaker module 61, the miniature circuit breaker module 62, and the lightning protection module 63 are sequentially arranged on the front of the mounting plate 30, and the intelligent electric meter module 65, the intelligent monitoring module 64, and the control circuit board 50 are sequentially arranged on the back of the mounting plate 30. It can be understood that the position of each module can be adjusted according to actual needs.

[0070] The inner wall of the housing 11 includes a mounting surface 116, and the intelligent power module 40 is fixedly arranged on the mounting surface 116 of the housing 11 through a mounting member 41, and the intelligent power module 40 is arranged opposite to the control circuit board 50 in the installed state. The mounting member 41 can be a screw, etc. Of course, in other embodiments, the intelligent power module 40 can also be arranged on the mounting plate 30, which is not limited here.

[0071] For further information, please refer to Figure 3 as well as Figure 5-6 The inner wall of the shell 11 has two opposite sides respectively provided with guide grooves 16, and the two sides of the mounting plate 30 are respectively provided with guide rail portions 33, which protrude and extend from the two sides of the main body 31 in a direction perpendicular to the main body 31, so that the mounting plate 30 can be detachably mounted on the shell 11 by sliding the guide rail portions 33 into the guide grooves 16.

[0072] It can be understood that by setting the guide rail portion 33 at the end of the mounting plate 30 and setting the guide groove 16 on the inner wall of the shell 11, the mounting plate 30 can be stably mounted on the shell 11 by sliding the guide rail portion 33 of the mounting plate 30 into the guide groove 16.

[0073] In this embodiment, the cross-section of the guide rail portion 33 is dovetail-shaped, T-shaped, or circular. Accordingly, the guide groove 16 is in a shape matching the guide rail portion 33 , so that the mounting plate 30 can be mounted on the housing 11 more smoothly.

[0074] A guide portion 36 is recessed at the corner of the mounting plate 30, and the guide portion 36 is arc-shaped, so that the guide rail portion 33 of the mounting plate 30 can slide into the guide groove 16. In addition, a limiting portion (not shown) can also be provided at the end of the guide groove 16 to limit the position of the mounting plate 30 during the installation process.

[0075] Furthermore, a plurality of threading holes 34 are provided at positions near the guide rails 33 of the mounting plate 30, through which the cables of the intelligent monitoring module 64, the intelligent reset circuit breaker module 61, the miniature circuit breaker module 62, the intelligent power module 40, the control circuit board 50, the lightning protection module 63, the intelligent meter module 65 and the maintenance socket 67 pass. In addition, in the actual setting process, the cables through which AC power, i.e., strong power, flows can be arranged on one side, while the cables through which DC power, i.e., weak power, flows can be arranged on the other side, so as to affect each other.

[0076] A plurality of protective parts 38 are also provided on both sides of the mounting plate 30 . The plurality of protective parts 38 extend from the end of the mounting plate 30 in a direction perpendicular to the mounting plate 30 and are located between the threading hole 34 and the guide rail part 33 to prevent the cables from contacting the inner wall of the housing 11 .

[0077] The operation of the intelligent power supply and distribution integrated system 400 is described in detail below.

[0078] Compared with the prior art, the intelligent power supply and power distribution integrated device 100 provided in this embodiment can monitor and control each module by setting the intelligent monitoring module 64, thereby realizing remote intelligent control, and can timely and effectively control each module to reduce the risk of failure, and can also alarm to reduce further risk problems caused by the failure. At the same time, it is also convenient to quickly detect and locate the faulty module and repair it, thereby improving the maintenance efficiency.

[0079] Please refer to Figure 8 In this embodiment, the miniature circuit breaker 63 has the function of line or load leakage and overcurrent protection. The miniature circuit breaker 63 is used to control the on and off of the first type of AC load. The miniature circuit breaker 63 is electrically connected to the intelligent monitoring module 64, so that the intelligent monitoring module 64 can monitor the working state of the miniature circuit breaker 63 in real time. When the circuit of the first type of AC load fails or is damaged, the miniature circuit breaker module 62 automatically trips and cuts off the power. The intelligent monitoring module 64 monitors that the miniature circuit breaker module 62 is in a disconnected state and sends an alarm signal to the external device 300 for alarm.

[0080] Further, the intelligent reset circuit breaker module 61 includes a first intelligent reset circuit breaker 611 and a second intelligent reset circuit breaker 612. In this embodiment, the intelligent reset circuit breaker module 61 is an intelligent reset circuit breaker module of GEWISS (Gaiweisi) of Italy. The first intelligent reset circuit breaker 611 is used to control the on and off of the second type of AC load. The first intelligent reset circuit breaker 611 is electrically connected to the intelligent monitoring module 64, so that the intelligent monitoring module 64 can monitor the working state of the first intelligent reset circuit breaker 611 in real time, and control the first intelligent reset circuit breaker 611 according to demand. In this embodiment, the second type of AC load is a 5G device. It can be understood that different devices are used according to actual needs.

[0081] The second intelligent reset circuit breaker 612 is used to control the on and off of the DC load electrically connected to the intelligent power module 40. The second intelligent reset circuit breaker 612 is electrically connected to the intelligent monitoring module 64, so that the intelligent monitoring module 64 can monitor the working state of the second intelligent reset circuit breaker 612 in real time and control the second intelligent reset circuit breaker 612 according to demand.

[0082] It can be understood that the first type of AC load, the second type of AC load, and the DC load are not limited to the devices exemplified in this embodiment. According to actual needs, 5G or 6G mobile communication micro base stations, camera devices, information interaction display screens, WIFI devices, one-button alarm devices, temporary charging devices, meteorological monitoring devices, etc. are used.

[0083] The intelligent power module 40 includes an AC / DC rectifier unit and an electric quantity collection and control output unit. The number of intelligent power modules 40 is 3. It is understood that the number can be adjusted according to actual needs, for example, at least one intelligent power module 40. It is understood that the number of intelligent reset circuit breaker modules 61 and intelligent power modules 40 can be selected according to the load's requirements for current properties (AC or DC) and voltage size (220V, 5V, 12V, 48V, etc.), which is not limited here.

[0084] After the external power passes through the second intelligent reset circuit breaker 612, it is converted into a DC power supply by the AC / DC rectifier unit and supplied to the DC load. The power collection and control output unit is used to collect the power of the DC load and control the power output to the DC load. The intelligent power module 40 transmits the collected data to the intelligent monitoring module 64. The power collection and control output unit outputs 220V, 48V, 12V and 5V DC power supplies to the DC load according to demand. Since DC voltages of various specifications can be output, various different DC load devices can be controlled, expanding the application scenarios of the intelligent power supply and power distribution integrated device 100.

[0085] It can be understood that the power collection and control output unit can also be used to collect the power of the AC or DC load and control the power output to the AC or DC load, and can be designed according to actual needs.

[0086] The intelligent monitoring module 64 monitors the working status of the miniature circuit breaker module 62 , the first intelligent reset circuit breaker 611 , and the second intelligent reset circuit breaker 612 , and receives relevant data from the lightning protection module 63 , the intelligent meter module 65 , and the intelligent power module 40 .

[0087] According to statistics, among all low-voltage circuit breaker tripping events, about 20% of the faults are caused by permanent faults of circuits or load equipment, and about 80% of the faults are caused by accidental reasons such as lightning overvoltage, operating overvoltage, earthquakes, typhoons, etc. Temporary faults account for more than 90% of the total circuit faults, and the duration is very short, ranging from a few milliseconds to a few seconds. The types of tripping of the intelligent reset circuit breaker module 61 include tripping caused by permanent faults and tripping caused by temporary faults.

[0088] The first intelligent reset circuit breaker 611 and the second intelligent reset circuit breaker 612 not only have the line or load leakage and overcurrent protection functions, but are also particularly used for periodically automatically detecting the second type of AC load or DC load and the circuit breaker body.

[0089] When a temporary fault occurs to the second type of AC load (for example, lightning interference), the first intelligent reset circuit breaker 611 trips in time, and after tripping, it can periodically and continuously detect the second type of AC load. After the temporary fault is eliminated, the first intelligent reset circuit breaker 611 can close within a few seconds and perform automatic reset, so that the second type of AC load can automatically resume power supply.

[0090] When the fault is manifested as overcurrent or leakage of the line or load, or aging of the circuit breaker itself (for example, a line fault of the second type of AC load, or a fault of the second type of AC load itself, i.e., a permanent fault), the first intelligent reset circuit breaker 611 trips in time. While disconnecting the second type of AC load, the first intelligent reset circuit breaker 611 outputs an alarm to the external device 300 (for example, the monitoring background) in real time via the intelligent monitoring module 64 for such faults. Periodic detection and alarm output of the intelligent reset circuit breaker module itself are optional functions of the intelligent reset circuit breaker module.

[0091] When a temporary fault occurs in the DC load (for example, a fault caused by the external environment, i.e., a circuit breaker tripping caused by high temperature, humidity, or lightning interference), the second intelligent reset circuit breaker 612 trips in time, and after tripping, it can periodically and continuously detect the DC load. After the temporary fault is eliminated, the second intelligent reset circuit breaker 612 can close within a few seconds and perform automatic reset, so that the DC load automatically resumes power supply.

[0092] When the fault is manifested as overcurrent or leakage of the line or DC load, or aging of the circuit breaker itself (for example, a line fault of the DC load, or a fault of the DC load itself, i.e., a permanent fault), the second intelligent reset circuit breaker 612 trips in time. While disconnecting the DC load, the second intelligent reset circuit breaker 612 outputs an alarm to the external device 300 (for example, the monitoring background) via the intelligent monitoring module 64 in real time for such faults. Periodic detection and alarm output of the intelligent reset circuit breaker module itself are optional functions of the intelligent reset circuit breaker module.

[0093] Furthermore, the intelligent power supply and power distribution integrated device 100 may be optionally provided with a lightning protection module 63. The lightning protection module 63 is used to protect all miniature circuit breakers 62, intelligent reset circuit breaker modules 61, intelligent meter modules 40, intelligent monitoring modules 64, and all loads from lightning strikes and overvoltage. In addition, a dry contact signal interface is provided on the lightning protection module 63, and its working status and number of lightning strikes are collected by the intelligent monitoring module 64 in the form of signal output. The intelligent monitoring module 64 transmits the collected relevant signals to the external device 300. The relevant data serves as an important basis for backstage personnel monitoring and operation and maintenance. In this embodiment, the lightning protection module 63 is a lightning protection product that combines B and C-level active energy control technologies (AEC), and different lightning protection modules can also be set according to needs.

[0094] Furthermore, the intelligent power supply and power distribution integrated device 100 may be optionally provided with an intelligent meter module 65, which is used to collect relevant data for the first type of AC load, the second type of AC load and the DC load, display the relevant data, and transmit the relevant data to the intelligent monitoring module 64. The intelligent meter module 65 is used to collect relevant data such as voltage, current, frequency, power, leakage current, etc., and the relevant data is sent to the external device 300 via the intelligent monitoring module 64, so that the external device 300 can monitor the working state of the intelligent power supply and power distribution integrated device 100, and based on the relevant data collected by the intelligent meter module 65, the user can also accurately determine the cause of the failure of the intelligent power supply and power distribution integrated device 100.

[0095] Furthermore, the intelligent power supply and power distribution integrated device 100 may be optionally provided with an internal temperature sensor and a cooling fan 20. The internal temperature sensor and the cooling fan are electrically connected to the intelligent monitoring module 64, respectively. The internal temperature sensor is used to detect the temperature inside the housing 10. The intelligent monitoring module is set with a temperature threshold. After the internal temperature sensor detects the temperature, it sends the temperature data to the intelligent monitoring module. When the temperature data received by the intelligent monitoring module exceeds the threshold, the intelligent monitoring module controls the cooling fan to start and dissipate the heat inside the housing 10 of the multifunctional intelligent device 200; when the temperature inside the housing 10 drops to a normal range, the intelligent monitoring module controls the cooling fan to turn off.

[0096] It is understandable that the temperature-related threshold value can also be set in the external device 300. At this time, the internal temperature sensor sends temperature data to the intelligent monitoring module in real time, and the intelligent monitoring module sends the temperature data to the external device 300. When the external device 300 determines that the temperature data exceeds the threshold, the external device 300 sends an opening instruction to the intelligent monitoring module, and the intelligent monitoring module controls the cooling fan to start according to the opening instruction. When the temperature data received by the external device 300 drops to a normal range, the external device 300 sends a closing instruction to the intelligent monitoring module, and the intelligent monitoring module controls the cooling fan to close according to the closing instruction.

[0097] Further, the intelligent power supply and power distribution integrated device 100 may be optionally provided with a temperature and humidity sensor. The temperature and humidity sensor is electrically connected to the intelligent monitoring module. The temperature and humidity sensor detects the temperature and humidity of the external environment of the housing 10. The intelligent monitoring module 64 is set with a temperature threshold and a humidity threshold of the external environment. When the received humidity or temperature data exceeds the threshold, the intelligent monitoring module 64 sends an alarm signal to the external device 300 for alarm. When the humidity or temperature-related threshold is set in the external device 300, the temperature and humidity sensor sends the humidity and temperature data to the intelligent monitoring module in real time, and the intelligent monitoring module sends the humidity and temperature data to the external device 300. When the external device 300 detects that the received humidity or temperature data exceeds the threshold, the external device 300 issues an alarm. The external environment of the housing 10 is monitored in real time by the temperature and humidity sensor to facilitate the intelligent monitoring of the intelligent monitoring module.

[0098] Further, the intelligent power supply and power distribution integrated device 100 may be optionally provided with a water immersion detection sensor. The water immersion detection sensor is electrically connected to the intelligent monitoring module 64. When the water immersion detection sensor detects water immersion in the housing 10, an alarm signal is sent to the intelligent monitoring module 64, and the intelligent monitoring module 64 receives the alarm signal and sends an alarm signal to the external device 300 for alarming. The external device 300 sends a shutdown command to the intelligent monitoring module 64, and the intelligent monitoring module 64 trips the miniature circuit breaker module 62, the first intelligent reset circuit breaker 611, and the second intelligent reset circuit breaker 612, so that all loads are powered off. By providing the water immersion detection sensor, the water immersion of the load equipment can be monitored, which is convenient for the monitoring and intelligent control of the intelligent monitoring module, so that when water is immersed, it is convenient to control the first intelligent reset circuit breaker 611 and the second intelligent reset circuit breaker 612 of the intelligent power supply and power distribution integrated device 100 to trip, thereby reducing the risk caused by the fault.

[0099] The intelligent power supply and power distribution integrated device 100 may be optionally provided with a smoke sensor. The smoke sensor is electrically connected to the intelligent monitoring module and is used to detect smoke inside the housing 10. When the smoke sensor detects smoke, it sends an alarm signal to the intelligent monitoring module, and the intelligent monitoring module sends the received alarm signal to the external device 300 for alarm.

[0100] Furthermore, the intelligent power supply and distribution integrated device 100 may be optionally provided with an access control module. The access control module is respectively arranged on the door of the multifunctional intelligent device 200 and electrically connected to the intelligent monitoring module. The access control module obtains the verification signal input by the user, and compares the verification signal with the preset signal. When the verification signal matches the preset signal, the access control module sends a door opening signal to the intelligent monitoring module to open the door of the multifunctional intelligent device 200. When the verification signal does not match the preset signal, the access control module sends an alarm signal to the intelligent monitoring module, and the intelligent monitoring module sends the received alarm signal to the external device 300 for alarm. Through the access control module, the opening of the warehouse door can be intelligently controlled, and an alarm can be sounded when the signal does not match, thereby realizing intelligent control and improving the safety of the warehouse body 201.

[0101] Further, the intelligent power supply and power distribution integrated device 100 can be optionally provided with a camera module. The camera module is electrically connected to the intelligent monitoring module. When the access control module determines that the verification signal does not match the preset signal, the intelligent monitoring module sends an alarm signal to the external device 300, and controls the camera module to start shooting the image outside the warehouse 201 of the multifunctional intelligent device 200 where the intelligent power supply and power distribution integrated device 100 is located, and the image is sent to the intelligent monitoring module. The intelligent monitoring module sends the received image to the external device 300, and the user views the image through the external device 300. After the user confirms the person on the image, the user immediately alarms, or sends a door opening command to the intelligent monitoring module through the external device 300, and the intelligent monitoring module opens the warehouse door of the multifunctional intelligent device 200 after receiving the door opening command. By setting the camera module, the situation of opening the warehouse door without instructions can be effectively monitored. If the warehouse is opened forcibly, an alarm will be immediately triggered, and an image or video capture will be performed, thereby improving the safety protection level of the warehouse 201.

[0102] The intelligent power supply and distribution integrated system provided by the patent of this application has the characteristics of intelligence. The system realizes real-time monitoring and intelligent control of each load, line and key electrical components through the coordinated work of various internal modules, thereby reducing the risk caused by failures caused by internal and external environments and lines or loads. The monitoring module in the system can not only collect relevant data of the above-mentioned internal and external environments and lines or loads in real time, but also upload it to the external management platform, and issue an alarm when necessary, so as to facilitate the background to quickly detect and locate the fault points, remind the operation and maintenance personnel to perform maintenance in time, thereby improving maintenance efficiency. For load equipment that freezes due to excessive ambient temperature or long-term operation, the system management platform can issue instructions from the back end to restart or shut down the circuit breaker in the system, and intelligently power the load to activate the frozen load and let it work again, which has the effect of saving maintenance energy consumption.

[0103] [Second embodiment]

[0104] The structure of the intelligent power supply and power distribution integrated device 500 in the second embodiment is substantially the same as that of the intelligent power supply and power distribution integrated device 100 in the first embodiment, except that the housing 10 of the intelligent power supply and power distribution integrated device 500 is a closed structure.

[0105] A closed receiving chamber 14 is formed by the shell 11, the first cover plate 12 and the second cover plate 13, which can prevent water, dust or smoke particles from invading the receiving chamber 14, thereby avoiding short circuits, leakage, circuit corrosion, etc. in the internal electrical module and the circuit of the power electronic module.

[0106] Further, in this embodiment, please refer again to Fig. 9A breathing valve 15 is also provided on the second cover plate 13 to balance the air pressure inside and outside the housing 10. The breathing valve 15 is a well-known structure in the art and will not be described in detail herein.

[0107] Under normal circumstances, the breathing valve 15 is in a closed state. When the internal temperature of the receiving chamber 14 is higher than the external temperature, the pressure difference between the inside and outside of the receiving chamber 14 increases, and the valve plate of the breathing valve 15 automatically opens to discharge the hot air in the receiving chamber 14 and lower the internal temperature. When the internal temperature of the receiving chamber 14 is lower than the external temperature, the breathing valve 15 remains closed to avoid the inhalation of external pollutants and hot air.

[0108] It can be understood that by setting up the breathing valve 15, the air pressure balance inside and outside the shell 10 can be maintained when the external temperature is high or low, eliminating the possibility of cold and humid air entering the receiving cavity 14 through the cable and corroding the circuit, thereby effectively achieving the effects of waterproofing, dustproofing, anti-smoke particles, breathability, heat dissipation, and preventing condensation.

[0109] In addition, the position of the breathing valve 15 can be adjusted according to needs, for example, it can be set at any position of the housing 11, which is not limited here.

[0110] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present application rather than to limit them. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present application.
