Description

Technical Field

[0001] This invention relates to the field of cable testing technology, and in particular to a control method, apparatus, and equipment for a thermoplastic sealing device for communication cables. Background Technology

[0002] After production, communication cables need to be bundled into loops for easy transportation. To protect the cables, a plastic protective film is added to the outside of the loop. Current technology typically involves placing the plastic film over the loop and then feeding it into a heat-sealing device for heating and sealing. The temperature changes caused by heating and cooling cause the heated plastic film to pre-cool and shrink, tightly wrapping the loop. However, different types and sizes of cables use different plastic films, resulting in varying temperature changes required during heat sealing. Current technology sets the heat-sealing device to a fixed heating temperature and then cools it to room temperature. However, for larger cables, the temperature change is not drastic enough, often resulting in the plastic film not tightly wrapping the loop, affecting the reliability of the communication cable packaging. Therefore, existing technologies cannot reliably heat-seal various types of communication cables. Summary of the Invention

[0033] Please see Figure 1 and Figure 2 , Figure 1 This is a flowchart of a control method for a heat-sealing device for communication cables provided in an embodiment of the present invention. Figure 2This is a schematic diagram illustrating an application scenario of the control method for a heat-sealing device for communication cables provided in an embodiment of the present invention. The control method for the heat-sealing device for communication cables is applied to a controller 10 configured in the heat-sealing device 1. The controller 10 is communicatively connected to a heating wire 11, a fan 12, an inlet air temperature sensor 13, an inner cavity temperature sensor 14, and a conveyor motor 15 disposed within the heat-sealing device 1. The air outlet corresponding to the fan 12 is located downstream of the heating wire 11; the inlet air temperature sensor 13 is located at the air inlet corresponding to the fan 12; the inner cavity temperature sensor 14 is located below the heating wire 11; and the conveyor motor 15 drives the roller 151 to rotate. The controller 10 can be a microcontroller, an FPGA circuit, or other similar device. The specific device structure is as follows: Figures 3 to 5 As shown, the heat insulation cover 16 is mounted on the drive roller 151. The ring cable enters from one end of the heat insulation cover 16, is heated inside the heat insulation cover 16, and then exits from the other end. Rotation of the drive roller 151 drives the ring cable placed on it to move horizontally along the conveying direction. An air outlet is opened downstream of the heat insulation cover 16. A surrounding plate 17 surrounds the outside of the fan 12 to form an air duct. One end of the air duct connects to the air outlet, and the other end serves as an air inlet. A guide plate 18 is also provided at the air outlet to guide the airflow out of the outlet, that is, to direct the airflow to the ring cable below. Multiple flexible high-temperature resistant baffles 19 are provided below the guide plate 18. The baffles 19 separate the hot airflow from the airflow out of the outlet, and when the ring cable exits from the inner cavity, the ring cable can automatically open the baffles 19. Figure 1 As shown, the method includes steps S110 to S150.

[0034] S110. Receive the input cable parameters and obtain the corresponding molding control parameters according to the preset molding configuration table.

[0035] After the device is powered on, the user can input cable parameters, including cable type, cable weight, and cable manufacturing standards. The controller is equipped with a plastic encapsulation configuration table, which includes configuration parameters for encapsulating different cables. The corresponding plastic encapsulation control parameters can then be obtained from the plastic encapsulation configuration table.

[0036] In one embodiment, step S110 includes the following steps: obtaining the packaging specifications that match the cable weight in the packaging configuration table and the cable parameters; obtaining the insulation temperature and conveying speed corresponding to the cable type in the packaging configuration table and the packaging specifications and the cable parameters, as the corresponding packaging control parameters.

[0037] Specifically, you can obtain the packaging specifications that match the cable weight in the cable parameters from the shrink wrapping configuration table. Generally speaking, the external dimensions of the loop cable formed by bundling communication cables are proportional to the cable weight; therefore, the heavier the cable, the larger the plastic packaging size specified in the packaging specifications. The shrink wrapping configuration table includes multiple weight ranges, each corresponding to a packaging size. You can then obtain the packaging size corresponding to the weight range that matches the cable weight in the cable parameters, and use this as the appropriate packaging specification.

[0038] Further, obtain the insulation temperature and conveying speed corresponding to the cable type and packaging specifications and cable parameters from the shrink-wrapping configuration table. Specifically, the shrink-wrapping configuration table includes the withstand temperature corresponding to the cable type, which is the highest temperature that the communication cable can withstand without damage. After obtaining the withstand temperature matching the cable type, calculate the withstand temperature T. X Temperature difference T between the default heating temperature T0 and the temperature T c And set the default temperature rise coefficient r configured in the molding configuration table. T Multiply by the temperature difference T c With temperature interval T j The difference between them, the resulting product r T ×(T c -T j In other words, the allowable temperature rise while ensuring the safety of the communication cable is calculated. This temperature is then added to the default heating temperature to obtain the insulation temperature. Furthermore, the temperature ratio between the insulation temperature and the default heating temperature is obtained, and the product of this temperature ratio and the initial speed is calculated. The resulting product can be used as the conveying speed, which can improve the conveying efficiency of the loop cable while ensuring safety, thereby improving the efficiency of heat sealing the cable.

[0039] S120. The heating wire is heated and kept warm according to the molding control parameters and the internal cavity temperature detected by the internal cavity temperature sensor.

[0040] The internal temperature is further obtained from the internal temperature sensor, and the heating power of the heating wire is adjusted according to the internal temperature and the encapsulation control parameters, thereby controlling the heating of the heating wire and achieving heat preservation.

[0041] In one embodiment, step S120 includes the following steps: sending a heating command to the heating wire to control the heating wire to heat; determining whether the inner cavity temperature has reached the heat preservation temperature set in the encapsulation control parameters; if the inner cavity temperature reaches the heat preservation temperature, generating a corresponding heat preservation command according to the encapsulation control parameters and sending it to the heating wire.

[0042] Specifically, a heating command can be sent to the heating wire to control it to heat at a default heat dissipation. Further, it is determined whether the internal cavity temperature has reached the set insulation temperature in the encapsulation control parameters. If the internal cavity temperature reaches the set insulation temperature, an insulation command corresponding to the encapsulation control parameters is generated and sent to the heating wire, meaning the heat dissipation of the heating wire is reduced at this point. For example, the insulation command can be set to reduce the heat dissipation to 30% of the default heat dissipation. Furthermore, after entering the insulation stage, it is continuously monitored whether the internal cavity temperature drops below the insulation temperature. If the internal cavity temperature drops below the insulation temperature, a heating command is sent to the heating wire, and the process returns to the step of determining whether the internal cavity temperature has reached the insulation temperature. By cyclically executing the above temperature checks, the internal cavity temperature is controlled to remain near the insulation temperature.

[0043] S130. Generate a preparatory reminder message and generate a corresponding conveying control command based on the encapsulation control parameters, and send it to the conveying motor.

[0044] Once the equipment enters the heat preservation stage, a preparatory reminder message is generated. This message indicates to the operator that the equipment is ready and the heat sealing operation on the loop cable can begin. The preparatory reminder message can be an indicator light message and / or an audio message. Further, corresponding conveyor control commands are generated based on the sealing control parameters and sent to the conveyor motor.

[0045] In one embodiment, step S130 includes the following steps: obtaining the corresponding drive power based on the conveying speed in the encapsulation control parameters and the cable weight in the cable parameters; generating a corresponding conveying control command based on the drive power and sending it to the conveying motor.

[0046] Specifically, the corresponding drive power is obtained based on the conveying speed and cable weight parameters in the encapsulation control parameters. The drive power can be determined according to the linear relationship between the drive power, conveying speed, and cable weight, which can be expressed as P'=P0×V. s / V0×[a×(G x / G0) 2 +b×(G x / G0)+c];where P' is the required driving power, P0 is the initial power (fixed value), V s The conveying speed is V0, the initial speed (fixed value) is V0, and a, b, and c are the corresponding fitting parameters, which can be obtained by fitting multiple sets of experimental data. x Given the cable weight and G0 as the initial weight (fixed value), the delivery speed V in the encapsulation control parameters can be obtained through the above linear relationship. s The required drive power P' is determined. Based on the obtained drive power, a corresponding conveying control command is generated and sent to the conveying motor, thereby controlling the conveying motor to operate at that drive power.

[0047] S140. Send a pre-stored ventilation command to the fan and obtain the intake air temperature detected by the intake air temperature sensor.

[0048] Furthermore, a pre-stored ventilation command is sent to the fan, which is configured with a default ventilation power. After the fan starts working according to the ventilation command, airflow is generated in the duct. At this time, the temperature of the airflow at the air inlet can be detected in real time by the air inlet temperature sensor to obtain the corresponding air inlet temperature.

[0049] S150: Generate a power adjustment command corresponding to the air inlet temperature, the cavity temperature, the cable parameters, and the encapsulation control parameters according to the preset power adjustment strategy, and send it to the fan.

[0050] Furthermore, since the default ventilation power cannot adequately provide a matching temperature change for the plastic film on the outer layer of the loop cable, in order to further improve the reliability of heat sealing, a power adjustment command corresponding to the inlet air temperature, inner cavity temperature, cable parameters, and sealing control parameters can be generated according to the power adjustment strategy. The fan power can be adjusted through the power adjustment command, thereby adjusting the amount of cold air output to the loop cable. This allows the plastic film of the communication cable to obtain sufficient temperature changes and complete the cooling sealing, thereby improving the sealing effect.

[0051] In one embodiment, step S150 includes the following steps: configuring cooling capacity corresponding to the cable parameters and the encapsulation control parameters according to the cooling capacity configuration rules in the power adjustment strategy; obtaining a target airflow corresponding to the inlet air temperature, the cavity temperature, the encapsulation control parameters, and the cooling capacity according to the encapsulation cooling function set in the power adjustment strategy; obtaining a target power matching the target airflow according to the power matching rules set in the power adjustment strategy; and generating a corresponding power adjustment command based on the target power and sending it to the fan.

[0052] Specifically, the cooling capacity can be configured according to the cooling capacity configuration rules, corresponding to the cable parameters and encapsulation control parameters. This cooling capacity is then matched to the cooling capacity of the currently encapsulated ring cable. Further, the target airflow is obtained based on the encapsulation cooling function set in the power adjustment strategy, taking into account the inlet air temperature, internal cavity temperature, encapsulation control parameters, and cooling capacity. Once the target airflow is obtained, the target power matching the target airflow can be obtained according to the power matching rules. A corresponding power adjustment command is then generated based on the target power and sent to the fan to control the fan power adjustment; specifically, a PWM pulse signal corresponding to the target power can be generated as the power adjustment command and sent to the fan.

[0053] In one embodiment, configuring the cooling capacity corresponding to the cable parameters and the encapsulation control parameters according to the cooling capacity configuration rules in the power adjustment strategy includes: obtaining a cooling volume that matches the cable weight in the cable parameters; and obtaining a cooling capacity that matches the cooling volume and the insulation temperature in the encapsulation control parameters according to the cooling capacity configuration rules.

[0054] Specifically, to obtain the cooling volume that matches the cable weight in the cable parameters, the corresponding cooling volume can be obtained based on the packaging specifications that match the cable weight. For example, if the packaging specifications are a square with a side length of 0.4 meters and a height of 0.15 meters, the corresponding cooling volume can be calculated as h×π×(w / 2). 2 w is the side length, h is the height, and π is the value of pi.

[0055] Further, based on the cooling capacity configuration rules, obtain the cooling capacity that matches the insulation temperature in the cooling volume and sealing control parameters. The cooling capacity configuration rules include multiple sets of cooling capacity values, each corresponding to a volume range and a temperature range. The cooling capacity value that matches both the volume range and the cooling volume, and the temperature range and the insulation temperature, can be obtained as the cooling capacity. The unit of cooling capacity is kg•℃.

[0056] In one embodiment, obtaining the target airflow corresponding to the inlet air temperature, the cavity temperature, the encapsulation control parameters, and the cooling capacity according to the encapsulation cooling function set in the power adjustment strategy includes: calculating the temperature difference between the inlet air temperature and the cavity temperature; inputting the temperature difference, the cooling capacity, and the conveying speed in the encapsulation control parameters into the encapsulation cooling function for calculation to obtain the corresponding target airflow.

[0057] Furthermore, the temperature difference between the inlet air temperature and the inner cavity temperature can be calculated and denoted as ΔT. The obtained temperature difference, cooling capacity, and conveyor speed from the molding control parameters are input into the molding cooling function to calculate the corresponding target airflow. The molding cooling function can be expressed as:

[0058] (1);

[0059] Q represents the cooling capacity (kg•℃), L0 represents the cooling length of the loop cable during transport (a fixed value, m), and L0 can be determined by measuring the position of the cooling air that the loop cable can receive during transport; Vs represents the transport speed (m / s), and ρ represents the air density (kg / m³). 3 ), △T is the temperature difference, in °C, F x The target air volume to be calculated is expressed in meters (m³). 3 / s. The target air volume can be obtained by analyzing the above formula.

[0060] Furthermore, to improve the accuracy of obtaining the target air volume, the air density ρ can be corrected based on the inlet air temperature and current air pressure. According to physical principles, air density is related to temperature and pressure; therefore, the corrected air density can be obtained as follows:

[0061] (2);

[0062] ρ is the corrected air density, and ρ0 is the standard atmospheric pressure P. k and standard temperature T k Standard air density, T in P is the inlet air temperature. in This is the current air pressure (this can correspond to the air pressure value at the air inlet. Generally speaking, the air pressure at the location of the equipment does not change much, or you can directly use the air pressure value broadcast in the local weather information).

[0063] In the control method for a heat-sealing device for communication cables provided in this embodiment of the invention, the method includes: receiving input cable parameters after the device is powered on, obtaining corresponding heat-sealing control parameters according to the heat-sealing configuration table, controlling the heating wire to heat and maintain the temperature according to the heat-sealing control parameters and the internal cavity temperature; generating a preparatory reminder message and generating a conveying control command according to the heat-sealing control parameters and sending it to the conveying motor, sending a ventilation command to the fan and obtaining the air intake temperature; generating a power adjustment command according to the power adjustment strategy to adjust the output power of the fan accordingly. Through the above method, by detecting the internal cavity temperature and the air intake temperature, and adjusting the fan output power accordingly based on the cable parameters, it is ensured that the plastic film of each type of communication cable has a matching temperature change, thereby ensuring that the plastic film tightly wraps the ring cable to improve the reliability of heat sealing.

[0064] This invention also provides a control device for a heat-sealing device for communication cables. This control device can be configured in a controller 10 of the heat-sealing device 1.
