Description

Technical Field

[0001] This utility model relates to the field of metering instrument maintenance technology, and in particular to a multi-core cable calibration tool. Background Technology

[0002] During the maintenance of oilfield surface engineering equipment, operations such as frequency converter cabinet replacement and wellhead work often require disassembling the control cables of the data acquisition and control box and rewiring them after the work is completed. These cables typically contain dozens of wires, each of which must be precisely connected to the equipment port according to a unique serial number. However, existing technology has the following serious drawbacks:

[0003] 1. Line number markings are easily lost.

[0004] During the dismantling, transportation, and storage of cables, the original wire markings are easily worn or detached, making it impossible to identify the corresponding wires during reinstallation.

[0005] 2: Traditional cable alignment methods are inefficient.

[0006] Manual wire stripping method: Operators need to repeatedly strip the cable insulation layer to check the internal wire markings, which causes the effective length of the cable to be continuously reduced and results in serious material waste;

[0007] Multimeter testing method: This method requires two operators. One person fixes the probes at the beginning of the cable to contact the target wire, while the other person measures the continuity of each wire at the end and verbally verifies the serial number. This method has problems such as high labor costs, long operation time, and easy to cause incorrect connection due to communication errors. The average time for cable calibration is several hours.

[0008] 3: Safety hazards and insufficient reliability

[0009] Manual wiring cannot detect short circuit faults between conductors in real time, which can easily lead to short circuits and burnout of equipment after power-on.

[0010] Misoperation in a high-voltage environment may damage the testing equipment, which lacks an electrical isolation protection mechanism. Summary of the Invention

[0025] (III) Beneficial Effects

[0026] This utility model provides a multi-core cable alignment tool that can set independent power supply A and power supply B through a power module. Power supply A supplies power to the processor module, and power supply B supplies power to the detection module. This design achieves electrical isolation between the working power supply and the detection power supply, avoiding damage to the processor module caused by strong electrical interference or misoperation during the detection process, and improving the safety and reliability of the tool.

[0027] This testing module has several testing input ports, which can simultaneously connect multiple cables to be tested. Combined with the logic control of the processor module, it can measure each cable sequentially starting from a preset sequence number, achieving batch calibration with a single connection. Compared to the existing method of measuring each cable individually, this significantly reduces the number of calibration attempts and operation time, thus improving work efficiency.

[0028] As the control core, the processor module can receive the conduction signal from the detection module, generate wire sequence information, and transmit it synchronously to the storage module, prompt module, and display module.

[0032] The module consists of: 1: processor module; 2: power supply module; 3: detection module; 4: storage module; 5: prompt module; 6: display module; 7: input module. Detailed Implementation

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] In the description of this utility model, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "top", and "bottom" are all based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this utility model and simplify the description, and is not intended to indicate or imply that the indicated component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0035] like Figure 1 As shown, the present invention provides a multi-core cable alignment tool, comprising: a carrier circuit board and a tool housing;

[0036] The carrier circuit board is located in the tool housing, and an epoxy resin potting layer is filled between the tool housing and the carrier circuit board. The carrier circuit board serves as a physical integration platform for various functional modules. Through PCB traces, the circuit connections of processor module 1, power module 2, detection module 3, storage module 4, prompt module 5, display module 6 and input module 7 are realized to ensure the stability and reliability of signal transmission.

[0037] The tool housing provides mechanical protection, isolating external dust, oil, and other impurities, and is suitable for the complex environment of oilfield surface engineering. The tool housing serves as a carrier and is equipped with a composite button for the input module 7, an LED digital tube for the display module 6, and indicator lights for the prompt module 5, facilitating operation and status monitoring. The epoxy resin potting layer is used to prevent short circuits caused by moisture or external humidity intrusion of circuit board components, buffer mechanical vibrations during transportation or operation, protect internal precision electronic components, block the corrosion of circuits by oil and gas and corrosive gases, and extend the service life of the equipment.

[0038] The power module 2 includes: power supply A and power supply B, which are set independently. Power supply A is connected to processor module 1 and is dedicated to powering processor module 1, providing a stable operating voltage to ensure the stable operation of core circuits such as processor module 1 and storage module 4, and to avoid the main control program from crashing due to abnormal detection circuit.

[0039] Power supply B is connected to detection module 3 and supplies power to it independently, forming electrical isolation from power supply A. This design can prevent strong electrical interference that may be introduced by the wire under test during the test from directly entering the processor module 1, avoiding damage to core components and improving the safety and anti-interference capability of the tool. Traditional line calibration tools use a single power supply. If a short circuit or high voltage impact occurs in the detection circuit, it can easily lead to the burnout of the main control chip. This design limits the detection risk to the power supply B circuit through power isolation, ensuring the safety of the processor module 1 and achieving fault isolation between the detection power supply and the working power supply.

[0040] The output of the detection module 3 is connected to the input of the processor module 1. The detection module 3 has several detection input ports, which can connect multiple cables to be tested at the same time. Together with the calibration pen and the ground grid, a current loop is formed. During operation, the operator only needs to connect the wires once to test them one by one starting from the preset sequence number. The detection input ports of the detection module 3 support alligator clips or spring pin connectors, which can adapt to different specifications of wires and enhance the versatility of the tool.

[0041] The detection module 3 is equipped with an electrical isolation element, which can be an optocoupler, a magnetic isolation device, or a capacitive isolation device. The electrical isolation element can be selected according to the electromagnetic interference intensity, voltage surge risk, and portability requirements of the actual application scenario. The optocoupler transmits the conduction state through optical signals, blocking the electrical connection between the detection circuit and the processor module 1, preventing external high voltage from entering the processor module 1 through the wires, protecting the MCU components in the processor module 1, and ensuring real-time transmission of the detection signal. The magnetic isolation device uses the principle of electromagnetic induction to achieve signal isolation, has strong anti-electromagnetic interference capability, is suitable for the high-frequency electromagnetic environment of oil fields, and avoids detection signal distortion. The capacitive isolation device transmits signals through capacitive coupling, has a high isolation voltage, and can withstand instantaneous high voltage surges, further improving the reliability of the equipment under complex working conditions.

[0042] The output of the processor module 1 is connected to the storage module 4, the prompt module 5 and the display module 6 respectively. The input of the processor module 1 is connected to the input module 7. The processor module 1 processes the conduction signal input by the detection module 3 in real time.

[0043] The display module 6 includes several LED digital tubes, which are matched with the number of detection input ports of the detection module 3. The display module 6 is used to display the serial number of the wires connected to the detection input ports of the detection module 3, so that the operator can directly identify the wire serial number of the corresponding input port through the numbers displayed on the digital tubes without having to strip the cable sheath to check the wire number, thus avoiding cable damage caused by repeated stripping.

[0044] The prompt module 5 includes a buzzer, a continuity indicator light, and a short circuit alarm light. The continuity indicator light and the buzzer provide synchronous feedback with the display module 6 to achieve dual visual and auditory confirmation, which is especially suitable for noisy oilfield sites to avoid missed detections. The short circuit alarm light is independently installed on the outer wall of the tool housing.

[0045] The input module 7 uses a composite button, which is a mechanical self-reset switch. The contact pins of the composite button are directly connected to the input terminal of the processor module 1 through PCB traces, and the button cap of the composite button is exposed on the surface of the tool housing.

[0046] The storage module 4 includes a memory chip, the data interface of which is connected to the communication interface of the processor module 1. The storage module 4 is used to store the wire sequence number information generated by the processor module 1.

[0047] The following is a detailed description of the actual working scenario of a multi-core cable alignment tool.

[0048] In actual operation, one end of the cable to be tested is connected to the detection input port of the detection module 3, and the other end is connected to the ground grid using a calibration pen. This confirms that power supply A and power supply B of power module 2 are connected. Power supply A supplies power to processor module 1, and power supply B supplies power to detection module 3 to achieve electrical isolation.

[0049] Adjust the brightness of the LED digital tube in the display module 6 by pressing and holding the composite button on the input module 7 for 3 seconds to enter the brightness adjustment page and then pressing briefly to adjust the brightness to level 6.

[0050] A short press of the composite button on input module 7 performs a verification reset function, and processor module 1 clears the current state, and by default starts the detection from wire 1.

[0051] The composite key of input module 7 can be pressed twice to enter the storage function and retrieve the calibrated serial number and pre-stored shutdown time information;

[0052] The operator uses a wire tester to touch the wires to be tested one by one at the cable access end. Each time a wire is touched, the detection module 3 forms a current loop through the ground grid, triggering the isolation device of the corresponding input port to act. After receiving the conduction signal, the processor module 1 generates the wire number and drives the corresponding LED digital tube of the display module 6 to display the number, the buzzer of the prompt module 5 sounds, and the conduction indicator light lights up to achieve synchronous sound and light feedback.

[0053] If a wire is accidentally short-circuited, the detection module 3 detects the short-circuit loop, the processor module 1 generates a short-circuit alarm message, the short-circuit alarm light of the prompt module 5 flashes continuously, the buzzer emits a continuous alarm sound, and the display module 6 locks and displays the serial numbers of the short-circuited wires. The operator can directly locate the short-circuited wires according to the serial number prompts of the display module 6 without checking each wire one by one. After the wire calibration is completed, the processor module 1 automatically stores the wire serial number information into the memory chip of the storage module 4.

[0054] It is understood that the above-mentioned embodiments mentioned in this utility model can be combined with each other to form combined embodiments without violating the principle and logic. Due to space limitations, this utility model will not elaborate further.

[0055] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0056] This utility model provides a multi-core cable alignment tool, which sets independent power supplies A and B through power module 2. Power supply A supplies power to processor module 1, and power supply B supplies power to detection module 3. This design realizes electrical isolation between the working power supply and the detection power supply, avoids damage to processor module 1 caused by strong electrical interference or misoperation during the detection process, and improves the safety and reliability of the tool.

[0057] The detection module 3 is equipped with several detection input ports, which can simultaneously connect multiple cables to be tested. Combined with the logic control of the processor module 1, it can measure each cable sequentially starting from a preset sequence number, achieving batch calibration with a single connection. Compared to the existing method of measuring each cable individually, this significantly reduces the number of calibration attempts and operation time, thus improving work efficiency.

[0058] The processor module 1, as the control core, can receive the conduction signal from the detection module 3, generate wire sequence information, and synchronously transmit it to the storage module 4, the prompt module 5, and the display module 6. This mechanism realizes the automation of the wire calibration process, eliminating the need for manual verification of each wire. Reset, recall, and other operations can be completed simply by pressing the compound key on the input module 7, truly enabling one-person operation and reducing human error.

[0059] The storage module 4 can save the wire serial number information generated by the processor module 1. Operators can call up historical calibration data at any time through the input module 7 to avoid repeated calibration. This is especially suitable for scenarios where cables are disassembled and reassembled multiple times, further saving manpower and resources. The prompt module 5 provides real-time feedback on the calibration status through sound and light signals, and the display module 6 presents the wire serial number intuitively. Operators do not need to peel off the cable sheath to check the wire number, avoiding cable loss. At the same time, when a short circuit is detected, the prompt module and the display module can lock the short-circuited wire serial number to help quickly locate the fault and improve the calibration accuracy.

[0060] This multi-core cable calibration tool, through the coordinated operation of power module 2, processor module 1, detection module 3, storage module 4, prompting module 5, display module 6, and input module 7, solves the problems of time-consuming, error-prone, and multi-person operation in existing technologies, achieving efficient operation and significantly improving the efficiency and accuracy of cable calibration for oilfield data acquisition and control boxes.
