[0002] In recent years, with the acceleration of urbanization, the laying of cables has greatly increased. It can be said that cables are present in people's living environment, making their safety a very important issue, including their flame-retardant properties. This performance is mainly assessed through vertical burning tests on the cables. Currently, the main testing method involves using a vertical burning test machine to perform the test, and the final data reading and result interpretation must be done manually. However, this method is inconvenient and requires the tester to open the chamber door, exposing them to harmful combustion gases. Summary of the Invention

[0003] This application provides an intelligent ranging device, a method and apparatus for measuring cable combustion results, which can quickly and accurately determine the combustion results while avoiding contact with combustion gases for the test personnel.

[0004] In a first aspect, embodiments of this application provide an intelligent ranging device for measuring the vertical burning length of a cable.

[0019] When the second drive component is controlled by the control system to move the clamping piece included in the measuring component along the first direction, the movement data of the clamping piece collected in real time by the displacement sensor is obtained.

[0020] When the displacement sensor collects the same movement data at multiple consecutive moments, it is determined that the clip on the intelligent ranging device has moved to the first endpoint of the cable burning area.

[0026] In one possible implementation, determining the length of the cable burning area based on the duration and the moving speed of the measuring component when it moves to the second endpoint includes:

[0027] The updated duration is determined based on the ratio of the thickness of the clamp to the moving speed of the clamp and the duration.

[0028] The length of the cable burning area is determined based on the updated duration and the moving speed of the clip when it moves to the second endpoint.

[0033] In one possible implementation, the initial height of the clamps included in the measuring component is within a set height range including the ignition point of the cable during a combustion test. The clamps are perpendicular to the cable. When the bracket is located at the designated position, the wire core of the cable's combustion zone is perpendicular to the clamps and located between the two clamps.

[0034] In one possible implementation, the displacement sensor included in the measuring component is located on the clamping piece, and the determining module is configured to determine, by controlling the second driving component through the control system to move the measuring component along a first direction to the first endpoint of the cable burning area, as follows: when the second driving component controlled by the control system moves the clamping piece included in the measuring component along the first direction, the movement data of the clamping piece collected in real time by the displacement sensor is acquired; when the movement data collected by the displacement sensor at multiple consecutive moments is the same, it is determined that the clamping piece included in the measuring component has moved to the first endpoint of the cable burning area.

[0035] In one possible implementation, the determining module, when determining the time required for the measuring component to move at a constant speed along the second direction to the second end of the cable burning area, is specifically configured to:

[0036] After the control system controls the second drive component to move the clip included in the measuring component to the first end of the cable burning area, the moving speed of the clip when it moves in the second direction is determined.

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0056] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0057] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0058] An existing technology provides an automated measurement method for vertical combustion. After a set test time, a camera captures images and transmits them to a control system for analysis, thereby reducing personnel contact with combustion gases, improving testing efficiency, and ensuring personnel safety. However, the fixed position of the aforementioned camera is too close to the ignition point, making the equipment susceptible to smoke and high temperatures. Furthermore, the test results require photographing before analysis, resulting in limited intuitiveness.

[0059] This application provides a method and apparatus for measuring the combustion results of cables. After the combustion test, the cable remains in its pre-test clamped state. The carbonized area is measured using a mobile intelligent ranging device without opening the chamber door, thereby determining the combustion results. This eliminates the need to move the sample or open the chamber door, avoiding contact between the test personnel and the combustion gases, and enabling rapid and accurate acquisition and judgment of measurement data.

[0060] To better understand the embodiments of this application, the intelligent ranging device involved in this application will be briefly introduced below.

[0061] The intelligent ranging device provided in this application embodiment is used to measure the vertical burning length of cables. The intelligent ranging device includes a bracket, a measuring component, a first driving component, a second driving component, and a control system.

[0062] The measuring component is movably mounted on the bracket along the length of the cable and is used to measure the cable after it has burned. The first drive component drives the bracket to move closer to or away from the cable. The second drive component drives the measuring component to slide on the bracket. The control system is signal-connected to the first drive component and the second drive component respectively.

[0063] In some embodiments, the intelligent ranging device also includes a track that extends in a predetermined direction, and a support that is movable in the predetermined direction and engages with the track.

[0064] In some embodiments, the measuring assembly includes a movable side gripper and two clips fixed to the movable side gripper, which is movably mounted on a bracket along the length of the cable, and the distance between the two clips is less than the unburned diameter of the cable and greater than the diameter of the cable core.

[0065] In some embodiments, the measurement component further includes a displacement sensor for acquiring movement data of the measurement component.

[0066] In some embodiments, the intelligent ranging device also includes a reference side gripper, which is fixed to the end of the support away from the track.

[0067] In some embodiments, the bracket can be configured as a fixed rod, and the control system can be implemented through an electronic control unit (ECU).

[0068] See Figure 1 As shown, Figure 1 The structure of an intelligent ranging device is illustrated by way of example. The intelligent ranging device 100 includes a reference side gripper 10, a fixed rod 20, a movable side gripper 31, a clamping plate 32, a track 40, a first drive motor 51, a second drive motor 52, and an electronic control unit (ECU) 60.

[0069] The clamp 32 is fixed to the movable side gripper 31, which is movably mounted on the fixed rod 20 along the length of the cable. A first drive motor 51 drives the fixed rod 20 to move it closer to or away from the cable, and a second drive motor 52 drives the movable side gripper 31 to move it on the fixed rod 20. The ECU 60 is signal-connected to both the first and second drive motors. A track 40 extends in a set direction, and the fixed rod 20 is movable in that direction to engage with the track 40. In some scenarios, a reference side gripper 10 is fixed to the end of the fixed rod 20 away from the track 40, allowing the movable side gripper 31 to move within a specified height range on the fixed rod 20 via the second drive motor 52. The fixed rod 20 is perpendicular to the track 40, and the ECU 60 can control the first drive motor 51 to move the fixed rod 20 on the track 40 along arrow directions 1 and 2. In some scenarios, the clamp 32 is parallel to the track 40.

[0070] In some embodiments, the intelligent ranging device can be installed inside the test chamber. For example... Figure 2As shown, the cable 70 is vertically clamped between the clamps 80, and the intelligent ranging device 100 is set on one side of the cable 70. When the cable 70 is subjected to a burning test, it is conducted inside the housing 200. After the cable 70 is tested for burning, the fixed rod 20 on the intelligent ranging device 100 is controlled to move horizontally along the track 40 toward the cable 70. When it moves to the designated position, the burning result of the cable 70 after burning is measured.

[0071] In some embodiments, when the movable side gripper 31 moves vertically along the fixed rod 20, the height of the clamp 32 is the same as the height of the upper end of the cable 70 when the upper edge of the movable side gripper 31 coincides with the lower edge of the reference side gripper 10. When the lower edge of the movable side gripper 30 coincides with the upper edge of the track 40, the height of the clamp 32 is the same as the height of the lower end of the cable 70.

[0072] like Figure 3 As shown, Figure 3 This is a top view of the intelligent ranging device 100. The intelligent ranging device 100 has two clips 32, which are at the same height. The distance between the two clips 32 is less than the unburned diameter of the cable 70 and greater than the diameter of the cable core. In some scenarios, the clips 32 are perpendicular to the cable 70.

[0073] In some scenarios, the initial height of the clip 32 on the intelligent ranging device 100 is within a set height range, including the ignition point of the cable 70 during a combustion test. For example... Figure 4 As shown, testers can conduct a combustion test on cable 70 at ignition point 71. Furthermore, after cable 70 burns, the material on its surface changes, ultimately forming a burning area. In one possible scenario, cable 70 includes a burning area 72 and an unburned area 73, as shown... Figure 4 As shown in the figure. The gray area represents the combustion zone (i.e., the carbonized zone).

[0074] In some embodiments, Figure 5 This is a top-view cross-sectional view of the height of the moving side gripper when the intelligent ranging device 100 moves to the designated position. When the intelligent ranging device 100 moves to the designated position in the horizontal direction, the wire core 74 of the burning area of ​​the cable 70 is perpendicular to the clamp 32 and located between the clamps 32. At this time, the clamps 32 are controlled to move to one end of the burning area 72 of the cable 70, and then, keeping the distance between the clamps 32 constant, the clamps 32 on the intelligent ranging device 100 are controlled to move at a constant speed to the other end of the burning area 72, and the time required for the movement is calculated. Further, the length of the burning area 72 is determined by the time and speed required for the clamps 32 to move from one end of the burning area 72 to the other end, and then the burning result of the cable 70 is determined to be qualified based on the length of the burning area 72.

[0075] It should be noted that the above Figure 1-5 This is merely an example, and the embodiments of the present invention are not intended to limit the scope of the invention.

[0076] This application provides a method for measuring cable burning results based on an intelligent ranging device. See [link to relevant documentation]. Figure 6 As shown, the specific process of this method is as follows:

[0077] 601. When the set test time is reached during the combustion test of the cable vertically clamped in the fixture, the first drive component is controlled by the control system to move the bracket to the designated position in the horizontal direction.

[0078] The initial height of the clamp included in the measuring component is within a set height range, including the ignition point of the cable during a combustion test. For example, if the ignition point is located at a height of 15 cm from the bottom end of the cable, the set height range can be set to 13-17 cm from the bottom end of the cable. Preferably, due to the combustion characteristics, the initial height of the clamp can be set to be the same as or slightly higher than the ignition point height of the cable.

[0079] In some embodiments, the distance between the clips is less than the unburned diameter of the cable but greater than the diameter of the cable core. When the bracket moves horizontally, the clips are perpendicular to the cable, and when the bracket is in a designated position, the cable core in the burning area is perpendicular to the clips and located between them. Taking the bracket as a fixing rod as an example, after the cable surface material undergoes a combustion test, the surface material is carbonized. When the fixing rod 20 moves to the designated position, the clips 32 separate the carbonized surface material at the initial height of the burning area from the core. The position between the clips 32 and the cable 70 is as follows: Figure 7 As shown.

[0080] 602, when the second drive component is controlled by the control system to move the measuring component along the first direction to the first end of the cable burning area, the second drive component is controlled by the control system to move the measuring component along the second direction at a constant speed to the second end of the cable burning area, and the time required for the measuring component to move along the second direction at a constant speed to the second end of the cable burning area is determined.

[0081] In one possible implementation, the measuring component of the intelligent ranging device 100 also includes a displacement sensor, which can be fixed to a clip. For example... Figure 8 As shown, the displacement sensor 33 is fixed to the clamp 32. When the moving gripper 31 moves, it drives the clamp 32 to move, and thus the movement data of the clamp 32 collected by the displacement sensor also changes. In another possible implementation, the displacement sensor 33 can also be directly fixed to the moving gripper, such as... Figure 9 As shown, the displacement sensor 33 is located on the moving side gripper 31.

[0082] Furthermore, the movement of the measuring component to the first endpoint of the cable burning area by controlling the second drive assembly via the control system to move the clamping piece included in the measuring component along the first direction can be determined as follows: when the second drive assembly is controlled by the control system to move the clamping piece along the first direction, the movement data of the clamping piece collected in real time by the displacement sensor is acquired. Further, when the movement data collected by the displacement sensor at multiple consecutive moments are the same, it is determined that the clamping piece included in the measuring component has moved to the first endpoint of the cable burning area. Continuing with the above example, the positional relationship between the clamping piece and the cable is as follows: Figure 7 As shown. For example, the first endpoint is... Figure 4 The first direction is vertically upward, at the upper end of the cable burning area 72. When the clamp 32 starts to move, the displacement sensor 33 begins to collect the movement data of the clamp 32. When the clamp 32 moves to the upper end of the burning area 72, since the distance between the clamps 32 is less than the unburned diameter of the cable 70, the clamp 32 stops moving, and the displacement sensor 33 also stops moving. At this time, the movement data acquired by the displacement sensor 33 no longer changes. When the movement data collected by the displacement sensor 33 is the same at multiple consecutive moments, it can be determined that the clamp 32 on the intelligent ranging device 100 has moved vertically upward to the upper end of the cable burning area 72.

[0083] In some embodiments, after the clamping piece of the measuring component moves along the first direction to the first end of the cable burning area, the second driving component can be controlled by the control system to move the measuring component at a constant speed along the second direction to the second end of the cable burning area. The second direction is the opposite of the first direction.

[0084] In some scenarios, the time required for the measuring component to move at a constant speed along the second direction to the second end of the cable burning area can be determined as follows: After the second drive component controlled by the control system moves the clamping piece included in the measuring component to the first end of the cable burning area, the moving speed of the clamping piece along the second direction is determined. The control system controls the second drive component to move the clamping piece from the first end to the second end along the second direction at the moving speed and starts timing. Further, the movement data of the clamping piece collected in real time by the displacement sensor can be acquired. When the movement data collected by the displacement sensor at two consecutive moments are the same, it is determined that the clamping piece has moved to the second end and timing ends, thus obtaining the time it takes for the clamping piece to move from the first end to the second end along the second direction.

[0085] For example, continuing with the above example, the second direction is the vertically downward direction. When the clip moves vertically upward to the upper end of the cable burning area, the clip can be controlled to start moving vertically downward, and the moving speed of the clip during vertical downward movement can be determined. As an example, the moving speed of the clip during vertical downward movement can be set to 2 cm / s. Timing starts when the clip begins to move vertically downward. When the movement data of the clip collected by the displacement sensor at two consecutive moments are the same, it is determined that the clip has moved to the lower end of the burning area, and the timing ends, thus obtaining the time it takes for the clip to move from the upper end of the cable burning area to the lower end along the moving speed.

[0086] 603. The length of the cable burning area is determined based on the duration and the speed at which the measuring component moves to the second endpoint.

[0087] For example, if the time it takes for the clip to move from the first end point to the second end point along the second direction is 20 seconds and the moving speed is 2cm / s, then the length of the cable burning area can be determined to be 40cm based on the time and the moving speed of the clip.

[0088] In some scenarios, due to the thickness of the clip, there may be errors in determining the time it takes for the clip to move from the first endpoint to the second endpoint. Therefore, when determining the length of the cable burning area based on the time and the moving speed of the measuring component when it reaches the second endpoint, it can be determined as follows: Based on the ratio of the clip thickness to the moving speed of the measuring component and the time, determine the updated time. Then, determine the length of the cable burning area based on the updated time and the moving speed of the measuring component when it reaches the second endpoint. For example, if the clip thickness is 0.2 cm and the moving speed is 2 cm / s, the ratio of the clip thickness to the moving speed of the measuring component is 0.1. Therefore, the updated time is the sum of the ratio and the original time, which is 20.1 seconds. The updated length of the burning area is then 20.1 * 2 = 40.2 cm.

[0089] 604. When the length meets the set conditions, the cable burning result is deemed qualified.

[0090] In some embodiments, the condition is set that the length of the burned area of ​​the cable is less than 49 cm. When the measured length of the burned area is 40.2 cm, the condition is met, and the cable burning result is determined to be acceptable. In some scenarios, if the measured length of the burned area is 52 cm, the condition is not met, and the cable burning result is determined to be unacceptable.

[0091] In some embodiments, the measured length of the cable burning area can be displayed on the screen, along with the cable burning results, so that testers can intuitively understand the burning test results.

[0092] In some scenarios, once the cable burning results are deemed acceptable, the control system controls the first drive assembly to move the bracket horizontally from a designated position to an initial position, and then controls the second drive assembly to move the measuring component to an initial height. For example, if the initial height of the clamp is 15 centimeters, after the bracket moves horizontally to the initial position, the clamp moves to a height of 15 centimeters to facilitate the next measurement.

[0093] Based on the above scheme, after the measurement is completed, the clamp is moved to the initial height, which facilitates the next measurement.
