Description

Technical Field

[0001] The present invention relates to the technical field of distribution detection, and particularly to an intelligent monitoring system for a distribution automation terminal. Background Art

[0002] When supplying power, a power distribution cabinet is required. The existing power distribution cabinet adopts an automation terminal technology, which can monitor the power supply situation, safety, faults, etc. of the circuit through a variety of detection modules to ensure power supply safety, and can automatically repair or assist manual rapid positioning and searching after problems occur.

[0003] For the existing power distribution cabinet, the inside of the cabinet is generally detected through a gas detection module, etc. When factors such as overheating of the power supply or long-term use in a harsh environment may cause problems such as combustion or softening and rupture of the wire outer skin, the insulation protection will be lost, which is likely to cause greater accidents. Although it can be detected in time through gas changes, however, by the time the problem is discovered, the power supply stability has been affected, and more time is required for fault cleaning and repair, and it is not preventive and cannot give early warnings. Therefore, the existing monitoring technology fails to monitor the safe use of wires in place, and the problem of being unable to predict the occurrence of faults in advance needs to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is, aiming at the above-mentioned existing technical deficiencies, to provide an intelligent monitoring system for a distribution automation terminal, which solves the problems that the existing monitoring technology fails to monitor the safe use of wires in place and cannot predict the occurrence of faults in advance.

[0005] The technical solution adopted by the present invention is: to provide an intelligent monitoring system for a distribution automation terminal, including a manipulator, the working end of the manipulator is provided with a control box rotatably arranged, the control box is provided with two relatively movable clamping jaws, a master control box is arranged inside the cabinet body, the master control box communicates with a remote control end, the master control box controls the manipulator, and it is characterized in that the manipulator is arranged inside the cabinet body or on the inner side of the cabinet door of the power distribution cabinet, the two clamping jaws can clamp on the wire outer skin from two directions, the front side and the side, the master control box numbers and differentiates each wire outer skin in turn, and further includes:

[0006] Two pressure detection modules, the two pressure detection modules are respectively arranged on the two clamping jaws, and the detection ends of the two pressure detection modules are used for clamping the wire outer skin to detect the wire outer skin diameter and / or hardness;

[0007] A graphic recognition module is arranged on the control box for detecting the wire outer skin diameter;

[0008] Wherein, both the pressure detection module and the graphic recognition module communicate with the master control box.

[0009] To further optimize this technical solution, the graphic recognition module is two infrared detection components, and the two infrared detection components are respectively arranged on the two grippers for detecting the diameter of the wire outer skin.

[0010] To further optimize this technical solution, it further includes:

[0011] The first temperature monitoring module is arranged in the cabinet for detecting the temperature in the cabinet;

[0012] The second temperature monitoring module is arranged on the control box for moving with the control box to detect the temperature of the local area in the cabinet. Both the first temperature monitoring module and the second temperature monitoring module communicate with the main control box.

[0013] To further optimize this technical solution, it further includes:

[0014] The active heat dissipation component is arranged at the lower part of the cabinet for cooling the cabinet, and the main control box controls the operation of the active heat dissipation component.

[0015] To further optimize this technical solution, the active heat dissipation component includes an air outlet pipe, the air outlet pipe is movably arranged in the cabinet, and the gripper can grip the air outlet pipe and move it to the side of the wire outer skin.

[0016] To further optimize this technical solution, it further includes:

[0017] The camera monitoring module is arranged in the cabinet and communicates with the main control box.

[0018] To further optimize this technical solution, it further includes:

[0019] The gas detection module is arranged in the cabinet and communicates with the main control box.

[0020] To further optimize this technical solution,

[0021] The alarm module is arranged on the cabinet and communicates with the main control box.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. When the wire is overheated, it will affect the quality of the wire outer skin. Under the operation of the multi-degree-of-freedom manipulator, the gripper can freely move within a large range in the cabinet and detect the diameter and hardness of the wire outer skin from two directions, namely the outside and the side. When there are changes in the wire outer skin, the change information can be detected in a timely manner, so as to predict the occurrence of accidents in advance or arrange maintenance and replacement in advance, etc.

[0024] 2. The gripper can detect the wire sheath from the front side or both side directions, avoiding the problem of insufficient comprehensiveness in recognition from a single direction. For example, when multiple wires are arranged side by side, there is insufficient deformation space on the side (left and right sides), and deformations such as softening and swelling occur from the front or rear sides. However, simply monitoring the change in the diameter of the wire sheath from the front side through pattern recognition cannot achieve effective monitoring. Therefore, the monitoring method in two directions is more comprehensive.

[0025] 3. The pressure detection module can detect whether the wire sheath is too hard or too soft. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0036] As Figures 1-5 shown, a smart monitoring system for a distribution automation terminal includes a manipulator 101. The working end of the manipulator 101 is provided with a control box 102 rotatably arranged. There are two relatively movable clamping jaws 103 on the control box 102. A main control box 104 is arranged inside the cabinet body 1. The main control box 104 communicates with a remote control end. The main control box 104 controls the manipulator 101. The manipulator 101 is arranged inside the cabinet body 1 of the distribution cabinet or on the inner side of the cabinet door. The two clamping jaws 103 can clamp the outer skin 2 of the wire from two directions, the front side and the side. The main control box 104 numbers and differentiates each outer skin 2 of the wire in sequence. It further includes: two pressure detection modules 3, which are respectively arranged on the two clamping jaws 103. The detection ends of the two pressure detection modules 3 are used to clamp the outer skin 2 of the wire for detecting the diameter and / or hardness of the outer skin 2 of the wire; a graphic recognition module 4, which is arranged on the control box 102 for detecting the diameter of the outer skin 2 of the wire. Among them, both the pressure detection module 3 and the graphic recognition module 4 communicate with the main control box 104.

[0037] During use, in the daily monitoring process, the manipulator 101 makes the control box 102 approach the front side of each wire outer skin 2 through the multi-degree-of-freedom arm joints. Detection can be carried out from the front side first. The control box 102 is located on the front side of the wire outer skin 2. The clamping jaws 103 are inserted from the left and right sides of the wire outer skin 2. After clamping, the diameter can be measured. When the detected value of the pressure detection module 3 reaches the set value, the diameter measurement with controlled variables can be achieved. When the diameter change value exceeds a certain numerical range, it can be determined that there is a potential safety hazard. According to the factory parameters of the wire outer skin 2, the two clamping jaws 103 can also set a slightly smaller clamping distance with reference to the diameter parameter, so that the pressure detection module 3 can detect the pressure. Through the change of the pressure value, it can be judged whether the wire outer skin 2 has changed in diameter, hardness, rupture and expansion, etc. Then, detection can be carried out from the side, such as the left or right side of the wire outer skin 2. The side direction can be perpendicular to the front side direction or at a certain angle. Detection is carried out from two different directions. During side detection, the detection method is the same as that of the front side detection. There can also be the following methods. When multiple wires are arranged in a row from left to right and it is inconvenient for the clamping jaws 103 to enter the space between the two wires, observe the wire outer skin 2 from the side. When multiple wires are in a row, directly perform graphic recognition detection on the side view of a row of wires by using the graphic recognition module 4 to measure the diameter. When the diameter of a single wire outer skin 2 expands and becomes larger, it can be compared with the value under normal conditions to confirm that there is a potential safety hazard for this row of wires. To ensure the reliability of detection, generally, a section of wire near the valve is prone to be damaged first. Therefore, the vulnerable section can be fixed on the cabinet body 1 through brackets, etc., to avoid shaking, dislocation, etc. that may affect detection.

[0038] When the clamping jaws 103 perform clamping detection, the detection is more comprehensive, but a lower detection frequency can be adopted. The graphic recognition module 4 can be used for daily high-frequency detection. After imaging, the system can count values such as the diameter or interval of the wire outer skin 2, and then judge whether there are significant changes. After the area with changes appears, the pressure detection by the clamping jaws 103 can be further carried out for confirmation.

[0039] Furthermore, the graphic recognition module 4 is two infrared detection components 401, and the two infrared detection components 401 are respectively arranged on the two clamping jaws 103 for detecting the diameter of the wire outer skin 2.

[0040] During use, the graphic recognition module 4 is a prior art. After taking pictures and imaging, the system can calculate the diameter, interval, orientation, etc., and can also judge the surface rupture of the wire outer skin 2. Infrared detection components 401 can also be used to detect the diameter. The two infrared detection components 401 respectively emit light to the wire outer skin 2. When the light is blocked, it is the boundary of the wire outer skin 2, and the distance between the two infrared detection components 401 is the diameter. The distance between the two clamping jaws 103 can be obtained through the data feedback of the manipulator 101 itself.

[0041] Further, it further includes:

[0042] A first temperature monitoring module, which is arranged in the cabinet body 1 and is used to detect the temperature inside the cabinet body 1;

[0043] A second temperature monitoring module, which is arranged on the control box 102 and is used to move with the control box 102 to detect the temperature of a local area inside the cabinet body 1. Both the first temperature monitoring module and the second temperature monitoring module communicate with the master control box 104.

[0044] During use, when there is a power problem leading to local overheating, or when the temperature is relatively high during daily use, the first temperature monitoring module can feedback the temperature inside the cabinet body 1, facilitating power regulation or increasing the attention to power supply in local areas. When the temperature rise is obvious or shows an abnormal change, the manipulator 101 carries the second temperature monitoring module to move and perform temperature perception detection on the local area around the second temperature monitoring module. By comparing the temperatures, the heat source is located, enabling remote operators to better understand the situation inside the power distribution cabinet and facilitating the judgment of whether maintenance intervention is required. The temperature monitoring module is an existing device and can be installed at a suitable position on the cabinet body 1, the control box 102 or the gripper 103, and is omitted in the drawings without illustration.

[0045] Further, it further includes: An active heat dissipation component 5, which is arranged at the lower part inside the cabinet body 1 and is used to cool the inside of the cabinet body 1. The master control box 104 controls the operation of the active heat dissipation component 5. The active heat dissipation component 5 includes an air outlet pipe 501, and the air outlet pipe 501 is movably arranged inside the cabinet body 1. The gripper 103 can grip the air outlet pipe 501 and move it to the side of the wire outer skin 2.

[0046] During use, when the temperature inside the cabinet body 1 rises, the active heat dissipation component 5 can be turned on to cool the inside. The active heat dissipation component 5 can be a blower for blowing air, which is an existing technology. It can blow air into the cabinet body 1. The air outlet pipe 501 can be a flexible pipeline. After the second temperature monitoring module measures the temperature, when the master control box 104 or the remote control terminal determines the local heat source area, it can control the gripper 103 to grip the air outlet pipe 501, so that the air outlet pipe 501 directly blows on the heat source area for cooling, achieving faster cooling and avoiding local rapid temperature rise and heat accumulation. The end of the air outlet pipe 501 can be a hard pipe to facilitate gripping by the gripper 103.

[0047] Further, it further includes:

[0048] A camera monitoring module, which is arranged inside the cabinet body 1 and communicates with the master control box 104. A gas detection module, which is arranged inside the cabinet body 1 and communicates with the master control box 104. An alarm module, which is arranged on the cabinet body 1 and communicates with the master control box 104.

[0049] In use, the manipulator 101 can calibrate and position each position through the internal coordinate system, calibrate and distinguish each wire outer skin 2, etc., and can also utilize the existing vision system. Corresponding monitoring modules can be set according to the monitoring requirements, such as a camera monitoring module, an alarm module, a gas detection module, etc., which are all existing technologies. Those skilled in the art can select and adapt them according to needs, and will not be elaborated herein. At the same time, no drawings are shown. Those skilled in the art can confirm the installation position and usage method, etc.

[0050] It can be understood that the present invention is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present invention, various changes or equivalent substitutions can be made to these features and embodiments. Additionally, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present invention.
