Description

Technical Field

[0001] This utility model relates to the field of electrical automation testing technology, and in particular to a device for detecting wiring errors in a hub electrical control cabinet. Background Technology

[0002] In the installation and maintenance of electrical control systems, the accuracy of wiring in hub electrical control cabinets directly determines the stability and safety of equipment operation. However, traditional wiring detection methods are generally inefficient and inaccurate. Currently, the industry mostly uses manual visual inspection or point-by-point measurement with a multimeter to determine the wiring status. Faced with hundreds or even thousands of terminals in large control cabinets, manual inspection is not only time-consuming and labor-intensive (for example, inspecting a 300-terminal control cabinet takes about 4 hours), but it is also prone to omissions and misjudgments. Statistics show that the misjudgment rate of incorrect or missing wiring during manual inspection is as high as 15%.

[0003] In the field of electrical control cabinet wiring testing, many existing technologies are dedicated to solving related problems, but certain limitations still exist. For example, the Chinese utility model patent "CN219016547U" discloses a "leakage detection device for electrical control cabinet wiring construction," which mainly focuses on the problem of inconvenient wire winding and unwinding during leakage detection. By setting up a storage box, winding wheels, and related reset and limiting mechanisms, it makes wire winding and unwinding more convenient. However, this patent does not cover the detection of wiring correctness, and cannot provide an effective means to detect key issues such as whether the wiring is correct and whether there are any incorrect or missing connections, thus failing to meet the need for correctness judgment in electrical control cabinet wiring testing.

[0004] For example, the Chinese invention patent "CN104614660A" proposes a "method and device for detecting the insulation of wiring in a control cabinet of a distributed control system." Its purpose is to detect the insulation of numerous wires in a control cabinet of a distributed control system. It achieves the testing of the insulation performance of each circuit through a series of complex operations, such as establishing a loop array and utilizing a programmable logic controller. However, this technology only focuses on insulation and does not detect whether the wiring connections in the electrical control cabinet are correct. In practical applications, the correctness of wiring is just as important as insulation; incorrect or missing connections can lead to serious electrical faults. Therefore, this patent is insufficient in terms of the completeness of wiring detection. Utility Model Content

Unless otherwise specified, embodiments of the present invention and the various features thereof can be combined with each other, all within the protection scope of the present invention.

[0020] Example 1 Please see Figure 1 This utility model embodiment provides a wiring error detection device for a hub electrical control cabinet; electrical control cabinets are widely used in various parts of the power system, from power plants to substations, to distribution networks and various industrial power consumption scenarios, and it is like the "nerve center" of power transmission and distribution.

[0021] The correctness of the incoming line sequence directly affects the smooth and stable flow of electricity into the control cabinet, thus impacting the power supply to subsequent equipment. Incorrect wiring, such as a reversed three-phase sequence, can trigger serious power accidents, such as three-phase motor reversal causing equipment damage, production line shutdowns, or even large-scale power outages, disrupting residents' lives and normal social production. Precise incoming line sequence detection and fault diagnosis can identify and correct these potential hazards in advance, ensuring the unimpeded flow of the power system's "blood vessels" and a continuous and stable supply of electricity to society. In modern industrial automation, many sophisticated and expensive devices rely on electrical control cabinets for stable and precise power support. The continuous operation of production lines places extremely high demands on the reliability of the power supply. Any brief power outage or fault can trigger a chain reaction, leading to the scrapping of products being processed, interruption of production processes, and requiring significant time and cost for restarting the production line through debugging and calibration. An effective incoming line sequence detection and fault diagnosis system can monitor the power status in real time, quickly locate the fault point, and provide timely solutions, minimizing downtime, maximizing production continuity, and improving overall production efficiency.

[0022] In electrical control systems, the electrical control cabinet is a core component, and the correctness of its internal wiring directly affects the safe and stable operation of the entire system. Traditional wiring inspection methods mainly rely on manual verification, which is not only inefficient but also prone to omissions and misjudgments. This is especially true when dealing with complex, large electrical control cabinets, where the difficulty and error rate of manual inspection increase significantly. While some wiring inspection equipment exists on the market, it suffers from drawbacks such as low accuracy, complex operation, and limited functionality, failing to meet the demands of rapid and accurate testing of modern electrical control cabinets. Therefore, there is an urgent need for a new type of wiring error detection device for hub electrical control cabinets to improve inspection efficiency and accuracy while reducing labor costs and inspection errors.

[0023] Therefore, this embodiment provides a wiring error detection device for a hub electrical control cabinet, which mainly adopts automated control technology to achieve comprehensive detection of the correctness, integrity, and quality of wiring in the factory's electrical control cabinet. Through a high-resolution camera and image processing algorithms, the system can identify the type, location, and connection status of the terminals, detecting whether wiring is missing, loose, or has visual defects. The automated control technology, through the cooperation of limit switches and transmission mechanisms, allows workers to complete complex detection processes with simple operation.

[0024] Please see Figure 1 and Figure 2This embodiment provides a wiring error detection device for hub electrical control cabinets, aiming to solve the problem of frequent wiring errors in existing factory hub electrical control cabinets, which is time-consuming, labor-intensive, and inefficient. Existing detection technologies are difficult to meet the needs of detecting the correctness of hub electrical control cabinet wiring, and suffer from technical problems such as lagging information technology, over-reliance on human experience, and lack of automated detection and result indication, resulting in poor quality, efficiency, and accuracy of detection results.

[0025] In this embodiment, the device automatically identifies the type, location, and connection status of the wiring terminals to ensure they match the standard template; it also detects missing terminals to ensure all terminals are correctly installed. For any issues, the wiring inspection process is monitored in real time, displaying the results and status. When wiring errors or quality problems are detected, the system automatically alarms and records the anomaly. The results of each inspection are recorded, including wiring correctness, completeness, and quality information. The inspection data is analyzed to generate statistical reports, helping to optimize production processes and improve product quality.

[0026] In this embodiment, the detection device includes a detection host 100 and a power module 130. The detection host 100 includes a built-in central processing unit, a memory, a surface-mounted operation panel, and a display module 120. The display module 120 includes a first display screen 121 and a second display screen 122. The operation panel includes function buttons and a touch control area. The first display screen 121 is used to display the detection results. The power module 130 is used to supply power to the detection host 100.

The detection host 100 also includes a hub detection module 140 for collecting wiring signals and a comparison analysis module 150 for judging the correctness of wiring. Both the hub detection module 140 and the comparison analysis module 150 are electrically connected to the detection host.

[0027] Further details reveal that one end of the signal acquisition circuit is directly connected to the incoming terminal block of the electrical cabinet, while its rear end is connected to the signal processing circuit. The signal processing circuit performs a series of processing steps on the received bus signals, including filtering, A / D conversion, and operational amplifier processing. After processing, the central processing unit of the signal processing circuit receives these signals and performs in-depth analysis and processing to ultimately obtain the bus input signal sequence.

[0028] Please see Figure 3In actual use, the incoming terminals of the hub cabinet first need to be numbered. The operator will then connect the incoming lines of the hub cabinet to the terminals inside the electrical control cabinet. At this time, the signal acquisition circuit in the hub detection module 140 starts working, acquiring these wiring signals. The acquired signals are then transmitted to the signal processing circuit for processing, and the processed signals are then transmitted to the central processing unit of the detection host 100. The central processing unit will transmit these acquired signals to the comparison and analysis module 150, which will compare and analyze the acquired wiring signals with a pre-stored standard wiring database to determine whether the wiring is correct.

[0029] If the wiring is confirmed to be correct after comparison and analysis, the first display screen 121 will show the message "Detection passed". At the same time, the indicator light 161 in the audible and visual alarm module 160 will emit a green light to indicate confirmation. Conversely, if the wiring is incorrect, the first display screen 121 will show the error message and the specific location of the error. The indicator light 161 will emit a red light and start flashing. At the same time, the speaker 162 will emit an alarm sound to remind the staff that there is a problem with the wiring.

[0030] During the testing process, all data is automatically stored in the memory. Testing personnel can view historical testing records or generate testing reports via the operation panel. Furthermore, testing personnel can export testing data to external devices via the USB interface or wireless transmission unit of the data storage and export module 180 for further analysis or archiving.
