Description

Technical Field

[0001] The present invention relates to the field of pipeline detection, and in particular to an intelligent cable assembly dedicated to a detector in a pipeline. Background Art

[0002] The dedicated internal detector for long-distance buried oil and gas pipelines works in a pressurized closed environment, and the entire detection structure needs to be pressure-resistant. With the different diameters of the pipelines, the design size of the detector also changes accordingly, and the density of various probes in the detector also changes according to the size of the equipment. The various probes and cables on the existing detectors are connected one-to-one, which facilitates the transmission of the detector's probe signal to a sealed cabin at a distant location. Due to the actual space limitations of the detector, too many incoming lines have caused the detector cables to be too complicated and impossible to arrange. Forcible arrangement will affect the strength of the detector's sealed cabin, making it even more difficult for the sealed cabin to withstand too many cables entering the cabin, limiting the detector's function.

[0021] To make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the following is a brief description of the present invention in conjunction with the attached Figures 1 to 9 The present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

[0022] The dedicated intelligent cable assembly for the pipeline detector used in this embodiment is mainly composed of a male connector 1, a female connector 2, a circuit board 3, a housing 4 and a fastening plate 5. The male connector 1 of the intelligent cable assembly is made by integral vulcanization, and the male connector 1 is connected to various probes of the pipeline detector by cables.

[0023] The female connector 2 is connected to the circuit board 3 and is placed in the housing 4 along with the circuit board. The circuit board 3 mainly includes an isolation chip, an FPGA system, and peripheral circuits connected to the FPGA system, including a power supply system and a clock system. The male connector 1 is plugged into the corresponding female connector 2, and the two are crimped and fixed by a fastening plate 5 to ensure that the connection between the male connector 1 and the female connector 2 is firm and prevented from being disengaged.

[0024] The connection between the female connector 2 and the circuit board 3 in this embodiment is as follows:

[0025] In this embodiment, eight 8-core female sockets are used as connector female heads. The output end of the 8-core female socket is connected to the signal isolation unit, the FPGA system, the single-ended input to differential output unit, and the single 8-core female socket in sequence. The eight connector female heads 2 are used to receive the detection data of each probe of the detector in the pipeline, among which four connector female heads 2 are connected to the first isolation chip U5, and the other four connector female heads 2 are connected to the second isolation chip U6. The specific circuit structure is as follows Figure 3-8 As shown, the SCK1_N pin of the 8-core female socket is connected to the Y3 pin of the first isolation chip U5, the MOSI1_N pin of the 8-core female socket is connected to the Y3 pin of the first isolation chip U5, and the remaining 7 8-core female sockets are connected in the same manner, which will not be repeated here.

[0026] The output pins SCK1_N and MOSI1_N of the first isolation chip U5 are connected to the IO81 and IO82 pins of the FPGA. Similarly, the output pins of the second isolation chip U6 are also connected to the IO end of the FPGA. The DMOSI pin and DSCK pin of the FPGA are connected to the single-ended input-add-drop output unit (model FIN1027K8X), and the DMOSI_N, DMOSI_P, DSCK_N, and DSCK_P pins of the single-ended input-add-drop output unit are connected to the input end of the single 8-core female socket, and the output end of the single 8-core female socket J4 outputs the signal to external components.

[0027] An epoxy resin layer for potting the outer shell 4 is also provided at the joint of the outer shell 4, which not only realizes module integration but also improves the overall high-pressure resistance.

[0028] The dedicated intelligent cable assembly for the pipeline detector in this embodiment has a line-merging function, which can reduce the number of cables entering the sealed cabin of the detector, save wiring space, greatly optimize the installation structure space of the detector, and improve the quality of the detector. This embodiment realizes the separate connection of the probe, that is, a new probe can be directly replaced after a probe is damaged. The existing solution is to make it as a whole. If a probe is damaged, the entire module needs to be replaced, which is a great waste of cost.

[0029] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
