Description

Technical Field

[0001] This invention relates to the field of cable accessory manufacturing technology, specifically to a cable accessory manufacturing control system based on smart wearable devices. Background Technology

[0002] Cable branch joints are an essential cable accessory in the actual cable laying process. They are pre-divided according to the functional categories of different core wires in the cable to achieve different connection functions. During the manufacturing and installation of cable accessories, it is necessary to judge the condition of the product and monitor the environmental conditions during the manufacturing and installation process. If moisture or impurities are present on the surface of the cable insulation during the manufacturing or installation process, it can easily cause partial discharge or water treeing problems in long-term operating cables, leading to cable failure.

Therefore, it is difficult to adapt to the testing of different products during spot checks or installation tests. While the method of using an electricity meter for continuity testing can determine whether there is a continuity problem, the complexity of operation and the assessment of its transmission performance result in poor reliability of the test results.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Please see Figure 1 As shown, in one embodiment, a cable accessory manufacturing control system based on a smart wearable device is provided, the system comprising:

[0059] The testing gloves include an insulating glove body, a sampling component, and a contact conductor;

[0060] The acquisition component and contact conductor are mounted on the insulating glove body. The acquisition component is used to acquire the color information of the core wire in the cable accessory. The contact conductor is used to make contact with the cable accessory and establish electrical connection.

[0061] The control module is used to execute the corresponding control strategy based on the collected color information of the cable accessories, and to judge the status of the cable accessories based on the detected electrical performance parameters under the corresponding control strategy.

[0062] The control module is equipped with a connector for connecting to cable accessories.

[0063] Through the above technical solution, this embodiment integrates the detection system in the cable accessory manufacturing process into the inspection glove based on visual recognition technology and smart wearable technology. The system collects the color information of the core wires in the cable accessory through a data acquisition component. The control module executes the corresponding control strategy based on the collected color information and then judges the status of the cable accessory based on the detected electrical performance parameters under the corresponding control strategy. In this process, the detection does not need to follow a preset sequence, greatly reducing the difficulty of detection. Furthermore, the integration of the contact conductor into the inspection glove facilitates the clamping and fixing of the cable accessory. More importantly, this embodiment sets different control strategies according to the function of different core wires, judging their transmission performance status by detecting electrical performance parameters. Compared to conventional single continuity detection, the judgment result is more comprehensive.

[0067] The control strategy is as follows:

[0068] When the contact conductor comes into contact with the core wire, the control voltage is U1 for a duration of t1; then the voltage is adjusted from U1 to U2 within a duration of t2, and the current and resistance data within the time periods of t1 and t2 are obtained, which will be used as the electrical performance parameters for testing.

[0069] Through the above technical solution, this embodiment provides a process for determining a control strategy. The cable tag color and detection control parameters are pre-set according to the type of core wire in the cable accessory. The detection parameters include the energizing voltage U1 and the energizing adjustment voltage U2. The image information of the core wire tag is acquired and identified by the acquisition component, and the corresponding detection control parameter is selected based on the identified color. When the contact conductor contacts the core wire, the control voltage is U1 for a duration t1. Then, the voltage is adjusted from U1 to U2 within a duration t2, obtaining current and resistance data during periods t1 and t2, which are used as detection electrical performance parameters. By acquiring the changes in electrical performance parameters under stable and voltage-boosted conditions, and then analyzing and judging through the detection electrical performance parameters, the state of the cable accessory can be evaluated more comprehensively and accurately.

[0070] It should be noted that the electrical performance parameters under the detection parameters are all test data, so their values ​​are all within the safe voltage range for the human body, and are isolated by insulating gloves, thus ensuring the safety of the system.

[0071] As one embodiment of the present invention, the process of determining the status of cable accessories includes:

[0072] Through formula Calculate and obtain the risk value V of cable accessories risk ;

[0075] The process of determining the condition of cable accessories also includes:

[0076] S1, [max{R] i}, min{R i}] and the standard interval [R0-R th R0+R th Compare:

[0077] If [max{R i}, mmin{R i}]∈[R0-R th R0+R th If the condition is met, proceed to step S3;

[0078] Otherwise, the cable accessory is deemed to be in an abnormal condition;

[0079] Where, max{R i} represents R during time periods t1 and t2. i Maximum value, mmin{R i} represents R during time periods t1 and t2. i Minimum value; R th This is the standard error;

[0080] S2. Compare [max{I(t)}, mmin{I(t)}] with the standard interval [I0-I... th ,I0+I th Compare:

[0081] If [max{I(t)}, mmin{I(t)}]∈[I0-I th ,I0+I th If the condition is met, proceed to step S3;

[0082] Otherwise, the cable accessory is deemed to be in an abnormal condition;

[0083] Where max{I(t)} is the maximum value of I(t) within time intervals t1 and t2, and mmin{I(t)} is the minimum value of I(t) within time intervals t1 and t2; th This is the standard error;

[0084] S3, Risk value V for cable accessories risk With preset threshold V thr Comparison:

[0085] If V risk ≥V thr If so, the cable accessory is determined to be in an abnormal state.

First, the acquired individual electrical performance parameters are judged, and [max{R i}, mmin{R i}] and the standard interval [R0-R th R0+R th If the comparison is not within the standard range, it indicates that there is damage to cable accessories or other abnormal conditions. Similarly, compare [max{I(t)}, mmin{I(t)}] with the standard range [I0-I... th ,I0+I th If the comparison is performed and the result is outside the standard range, it indicates an abnormality in the condition of the cable accessories. If the result meets the requirements, the cable accessory risk value V will be used. risk To make a judgment, specifically, the risk value V of the cable accessories. risk The analysis and judgment are based on the deviation of resistance and current and the stability of electrical performance data during time periods t1 and t2. Specifically, among them... This indicates an out-of-tolerance resistance condition. R0 is the value of this core wire under standard conditions, which is obtained according to the corresponding core wire standard. This represents the fluctuating state of the current during time periods t1 and t2. This represents the out-of-tolerance status of the current during time periods t1 and t2. Here, q1 and q2 are obtained by fitting the current data for time periods t1 and t2 from the test data. Therefore, the risk value V of the cable accessory is used. risk The calculation process enables the assessment of the risk status of cable accessories.
