[0035] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0036] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0037] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0038] Figure 1 This is a schematic diagram of the structure of a power distribution cabinet status detection system provided by an embodiment of the present disclosure. Figure 1 , the power distribution cabinet status detection system includes:

[0039] A first switch module 11, a first detection module 12, a second detection module 13 and a control module 14;

[0040] A control module 14, whose input end is used to be connected to the power distribution cabinet, and whose output end is connected to the first switch module 11; the control module 14 is configured to receive the operation mode information of the power distribution cabinet and control the connection state of the first switch module 11;

[0041] The first switch module 11 has an input end connected to the power distribution cabinet, and an output end connected to the first detection module 12 and the second detection module 12 respectively.

[0042] The control module 14 is used to detect and receive the working mode information of the power distribution cabinet, and control the working state of the first switch module 11 according to the working mode information of the power distribution cabinet. The first switch module 11 is used to receive the signal of the control module 14, and adjust the connection state of the circuit according to the signal of the control module 14. The first detection module 12 is used to detect the state of the power distribution cabinet in the first mode, and the second detection module 13 is used to detect the state of the power distribution cabinet in the second mode.

[0043] There are usually two types of distribution cabinets, low-temperature distribution cabinets and high-temperature distribution cabinets. When the distribution cabinet is a low-temperature distribution cabinet, the temperature of the distribution cabinet is usually -5℃ to 40℃. When the distribution cabinet is a high-temperature distribution cabinet, the temperature of the distribution cabinet is usually 0℃ to 60℃. The two distribution cabinets have different working modes and different working temperatures. Therefore, two different sets of detection devices are required to correspond to different working modes of the distribution cabinets.

[0044] Specifically, when the power distribution cabinet is a high-temperature power distribution cabinet, the power distribution cabinet sends a signal including the power distribution cabinet being a high-temperature power distribution cabinet to the control module 14. After receiving the signal that the power distribution cabinet is a high-temperature power distribution cabinet, the control module 14 controls the first switch module 11 to connect the circuit where the first detection module 12 is located, and the first detection module 12 starts to detect the working state of the power distribution cabinet. For example, when the power distribution cabinet is a high-temperature power distribution cabinet, the operating temperature range of the power distribution cabinet is 0°C to 60°C, and the detection module will perform detection within the range of 0°C to 60°C.

[0045] When the power distribution cabinet is a low-temperature power distribution cabinet, the power distribution cabinet sends a signal including the power distribution cabinet being a low-temperature power distribution cabinet to the control module 14. After receiving the signal that the power distribution cabinet is a low-temperature power distribution cabinet, the control module 14 controls the first switch module 11 to connect the circuit where the second detection module 13 is located, and the second detection module 13 starts to detect the working state of the power distribution cabinet. For example, when the power distribution cabinet is a low-temperature power distribution cabinet, the operating temperature range of the power distribution cabinet is -5°C to 40°C, and the detection module will perform detection within the range of -5°C to 40°C.

[0046] The power distribution cabinet state detection system receives the operation mode information of the power distribution cabinet through the control module 14, controls the connection state of the first switch module 11 according to the different operation modes, and then adjusts the working states of the first detection module 12 and the second detection module 13 to achieve accurate detection of the state of the power distribution cabinet. The advantage of this design is that the detection range of the detection device can be flexibly adjusted according to the actual operation state of the power distribution cabinet, ensuring the accurate measurement of the detection module, and meeting the detection requirements for the power distribution cabinet including multiple working modes.

[0047] In one embodiment, Figure 2 is a structural diagram of another power distribution cabinet state detection system provided by an embodiment of the present disclosure, referring to Figure 2 , the first detection module 12 includes:

[0048] A first temperature detection module 121 and a first humidity detection module 122;

[0049] The second detection module 13 includes: a second temperature detection module 131 and a second humidity detection module 132;

[0050] Input ends of the first temperature detection module 121 , the first humidity detection module 122 , the second temperature detection module 131 , and the second humidity detection module 132 are all connected to the first switch module 11 .

[0051] The first temperature detection module 121 is used to detect the temperature of the high-temperature power distribution cabinet. The first temperature detection module 121 includes a high-precision temperature sensor that can withstand and accurately measure the temperature value in a high-temperature environment, ensuring that it can still work reliably when the temperature inside the power distribution cabinet rises. The first humidity detection module 122 is used to detect the humidity of the high-temperature power distribution cabinet. The first humidity detection module 122 uses a high-temperature resistant humidity sensor that can accurately measure and report humidity values ​​in a high-temperature environment.

[0052] The second temperature detection module 131 is used to detect the temperature of the low-temperature distribution cabinet. The module includes a high-precision temperature sensor that can withstand and accurately measure the temperature value in a low-temperature environment to ensure that it can still work reliably when the temperature inside the distribution cabinet drops. The second humidity detection module 132 is used to detect the humidity of the low-temperature distribution cabinet. It also uses a low-temperature resistant humidity sensor to ensure accurate monitoring of the humidity in a low-temperature environment.

[0053] When the distribution cabinet is a high-temperature distribution cabinet, the internal temperature is high and the upper limit of humidity is low. When the distribution cabinet is a low-temperature distribution cabinet, the internal temperature is low and the upper limit of humidity is high. Different temperature detection modules detect different types of distribution cabinets. For example, low-pressure state: the relative humidity is generally maintained between 50% and 70%. Humidity below 50% may cause static electricity accumulation problems, while humidity above 70% may accelerate the aging of insulating materials, promote the rusting of metal parts, and increase the possibility of corona discharge and arcing. The normal operating temperature range of the distribution cabinet is -5°C to 40°C, so the first detection module 12 is used to detect the temperature range of -5°C to 40°C, and detect the humidity range of 50% to 70%. High-pressure state: the requirements for humidity are more stringent, the relative humidity is between 40% and 60%, and the temperature range is 0°C to 60°C. The second detection module 13 is used to detect the temperature range of 0°C to 60°C and detect the humidity range of 40% to 60%.

[0054] Specifically, when the control module 14 receives that the power distribution cabinet is a low-temperature power distribution cabinet, it controls the first switch module 11 to connect the circuit of the first detection module 12, and the first detection module 12 detects the low-temperature power distribution cabinet. When the control module 14 receives that the power distribution cabinet is a high-temperature power distribution cabinet, it controls the first switch module 11 to connect the circuit of the second detection module 13, and the second detection module 13 detects the high-temperature power distribution cabinet.

[0055] In one embodiment, referring to Figure 2 , the first switch module 11 includes:

[0056] SPDT switch;

[0057] The single-pole double-throw switch has a fixed end for connecting to a power distribution cabinet, a first movable end connected to a first detection module 12 , and a second movable end connected to a second detection module 13 .

[0058] The single-pole double-throw switch is used to receive information from the control module 14 and control the connection state of the first detection module 12 or the second detection module 13 .

[0059] Specifically, the single-pole double-throw switch includes a fixed end, a first movable end and a second movable end. The fixed end is connected to the power distribution cabinet, the first movable end is connected to the first detection module 12, and the second movable end is connected to the second detection module 13.

[0060] When the power distribution cabinet is a high-temperature power distribution cabinet, the control module 14 controls the first moving end of the single-pole double-throw switch to be connected and the second moving end to be disconnected, and at this time the first detection module 12 detects the high-temperature power distribution cabinet. When the power distribution cabinet is a low-temperature power distribution cabinet, the control module 14 controls the second moving end of the single-pole double-throw switch to be connected and the first moving end to be disconnected, and at this time the second detection module 13 detects the low-temperature power distribution cabinet.

[0061] In one embodiment, referring to Figure 2 , the power distribution cabinet status detection system also includes:

[0062] A sensing module 15, a second switch module 16 and a display screen 17;

[0063] The second switch module 16 has an input end connected to the first detection module 12 and the second detection module 13 respectively, an output end connected to the display screen 17 , and a control end connected to the sensing module 15 .

[0064] The sensing module 15 is used to sense specific information in the environment, such as human approach, light intensity, temperature and humidity changes, etc., and convert this information into electrical signals and transmit it to related components. The second switch module 16 is connected to the first detection module 12 and the second detection module 13 respectively. The second switch module 16 receives the temperature and humidity information inside or around the power distribution cabinet through these two input ends, and these data are collected in real time by the first detection module 12 and the second detection module 13. The display screen 17 is used to display the detection data of the first detection module 12 or the second detection module 13, which can intuitively present the operating status of the power distribution cabinet status detection system.

[0065] Specifically, after the sensing module 15 detects that there is someone near the distribution cabinet, it controls the second switch module 16 to close. At this time, the detection data of the first detection module 12 or the second detection module 13 is sent to the display screen 17, and relevant personnel can understand the status of the distribution cabinet based on the data of the distribution cabinet on the display screen 17.

[0066] This embodiment allows people near the power distribution cabinet to know the status of the power distribution cabinet in time. At the same time, when no one is near the power distribution cabinet, the display screen 17 stops displaying the status of the power distribution cabinet, thereby saving power resources.

[0067] In one embodiment, referring to Figure 2 , the sensing module 15 includes:

[0068] A human body sensing module 152 and a brightness sensing module 151;

[0069] The human body sensing module 152 and the brightness sensing module 151 are both connected to the control end of the second switch module 16 .

[0070] The human body sensing module 152 is mainly used to detect whether there is human activity around the power distribution cabinet. Usually, infrared, microwave and other technical principles are adopted. When someone enters the sensing range, the module can detect it in time and output the corresponding trigger signal. The brightness sensing module 151 is used to monitor the light intensity of the environment where the power distribution cabinet is located. When someone approaches the power distribution cabinet, the person will turn on the light attached to the power distribution cabinet. The brightness sensing module 151 senses the changes in ambient light, such as lighting, and outputs an electrical signal corresponding to the current light intensity. When the light intensity exceeds a certain value, it will promptly feedback to the second switch module 16 to control the second switch module 16 to close, and the display screen 17 starts working.

[0071] The output end of the human body sensing module 152 is connected to the control end of the second switch module 16. When the human body sensing module 152 detects that someone has entered the sensing range, it will send a trigger signal to the second switch module 16. The second switch module 16 closes the circuit according to the received signal and controls the display screen 17 to start working to ensure the safety of personnel or to make necessary operation records. The output end of the brightness sensing module 151 is also connected to the control end of the second switch module 16. When the ambient light intensity changes, the brightness sensing module 151 converts the new light intensity information into an electrical signal. When the light intensity exceeds a certain value, the second switch module 16 is closed and the display screen 17 starts working. The second switch module 16 is in an open state when it does not receive a signal to control the closing of the second switch module 16.

[0072] In one embodiment, referring to Figure 2 , the power distribution cabinet status detection system also includes:

[0073] A third switch module 18 and a short-range communication module 19;

[0074] The third switch module 18 has a control end connected to the sensing module 15 , an input end connected to the first detection module 12 and the second detection module 13 , and an output end connected to the short-range communication module 19 .

[0075] The third switch module 18 comprises a single-pole single-throw switch, and the connection port of the single-pole double-throw switch is divided into a fixed end and a movable end. The fixed end is connected to , and the first movable end is connected to the first detection module 12 and the second detection module 13 .

[0076] The third switch module 18 changes the on or off state according to the signal received from the sensing module. For example, when the sensing module 15 detects that a person is close to the power distribution cabinet or the light near the power distribution cabinet exceeds a certain value, the third switch module 18 is closed, and the short-range communication module 19 sends the information of the first detection module 12 and the second detection module 13 to the mobile terminal of the person near the power distribution cabinet; or when the light near the power distribution cabinet exceeds a certain value, the third switch module 18 is closed, and the short-range communication module 19 sends the information of the first detection module 12 and the second detection module 13 to the mobile terminal of the person near the power distribution cabinet.

[0077] After receiving the information, the short-range communication module 19 wirelessly transmits it to the mobile device of the person near the power distribution cabinet.

[0078] In one embodiment, referring to Figure 2 , the power distribution cabinet status detection system also includes:

[0079] Warning module 20;

[0080] The warning module 20 is connected to the control module 14 .

[0081] The alarm module 20 is responsible for triggering corresponding prompt information after detecting the working status of the power distribution cabinet to remind the operation and maintenance personnel to pay attention and take corresponding measures.

[0082] After receiving the temperature mode of the power distribution cabinet, the control module 14 controls the warning module 20 to enter different working states. For example, when the power distribution cabinet is a high-temperature power distribution cabinet, the control module 14 controls the warning module 20 to enter the first state. When the power distribution cabinet is a low-temperature power distribution cabinet, the control module 14 controls the warning module 20 to enter the second state. The warning mode may include but is not limited to sound and light alarms (such as buzzers, warning lights), text prompts on the display screen 17, etc.

[0083] Relevant personnel can learn about the working mode of the distribution cabinet when approaching it, which enhances the early warning capability of potential risks, effectively prevents faults from occurring or reduces the impact of faults, and improves the overall safety and reliability of the distribution cabinet system.

[0084] In one embodiment, referring to Figure 2 , the power distribution cabinet status detection system also includes:

[0085] Remote communication module 21;

[0086] The remote communication module 21 is connected to the control module 14 .

[0087] The remote communication module 21 is used to receive instructions and data from the control module 14. After the control module 14 performs data analysis and processing based on the status information of the power distribution cabinet and the information of the first switch module 11, the data, alarm information, control instructions, etc. that need to be transmitted remotely are sent to the remote communication module 21 through the interface. After receiving this information, the remote communication module 21 encodes it and sends it to the designated remote monitoring platform using the wireless communication network.

[0088] By introducing the remote communication module 21 and connecting it with the control module 14, remote monitoring of the status of the power distribution cabinet is realized. Operation and maintenance personnel can view the working mode of the power distribution cabinet in real time through the remote monitoring platform or mobile devices without going to the site in person, which reduces the cost of manual inspections and lays the foundation for the centralized monitoring and intelligent management of large-scale distributed power distribution facilities, which helps to improve the operation and maintenance level and fault handling speed of the entire power distribution system.

[0089] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
