[0032] The utility model is described in detail below in conjunction with the accompanying drawings.

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] Example 1

[0035] like Figure 1As shown, it is a structural schematic diagram of a leakage cable characteristic monitoring data analysis module of the utility model, including a data acquisition interface 1, a module housing 6, a data acquisition control board 3, a lithium battery board 4, a charging interface 5, an optical fiber connector 7, a power switch 8 and an indicator light 2; the data acquisition interface 1, the charging interface 5, and the optical fiber connector 7 are hardware interfaces, the data acquisition control board 3 is a PCB board, the lithium battery board 4 is an integrated battery pack, the power switch 8 is a push button switch, and the module housing 6 is a structural member.

[0036] The data acquisition control board 3 is connected to the data acquisition interface 1, the lithium battery board 4, the optical fiber connector 7, the power switch 8, the indicator light 2, and the charging interface 5;

[0037] The data acquisition interface 1 is an N-type radio frequency connector, which is connected to the leakage cable monitoring equipment through a radio frequency line and serves as an input port for leakage cable characteristic monitoring data. The optional model is N-50KFB3-2.

[0038] The N-type RF connector, with its high reliability and strong vibration resistance, ensures the stability and reliability of data transmission. In the leaky cable monitoring system, this stability is crucial because any data loss or distortion may affect the accurate judgment of the leaky cable status. Secondly, the N-type RF connector has excellent mechanical and electrical properties, can withstand large mechanical stress and electrical load, and is suitable for various complex working environments. There is a lot of dust in the tunnel, and the optical fiber is easily affected by the dust, which reduces the transmission performance. The use of RF head collection can effectively improve the stability of signal transmission in complex environments.

[0039] The data acquisition interface 1 is connected to the leakage cable monitoring device through the radio frequency line. The radio frequency line adopts a metal shielding layer, which can effectively prevent the signal from being stolen and interfered, and further improve the stability of data acquisition. In addition, the radio frequency line can realize remote data acquisition and real-time monitoring. This greatly improves work efficiency and reduces the frequency and cost of manual inspections. At the same time, real-time monitoring also makes the response to the leakage cable status more rapid. Once a problem is found, measures can be taken immediately to prevent the problem from expanding.

[0040] The data acquisition control board 3 is used to collect and analyze the leaky cable characteristic monitoring data;

[0041] The lithium battery board 4 is connected to the data acquisition control board 3 and is used to supply power to the module. The optional model is LPc1S5200.

[0042] The optical fiber connector 7 is used to receive optical signal data from the leakage cable monitoring device, and the optional model is FC-APC.

[0043] The power switch 8 is used as a switch of the leakage cable characteristic monitoring data analysis module, and an optional model is a micro switch of 6*6*4.3mm.

[0044] The indicator light 2 is used to indicate the working status of the leakage cable characteristic monitoring data analysis module, and can be an LED light emitting diode.

[0045] The charging interface 5 is used to charge the lithium battery board 4, and the optional model is a Micro 5P female socket.

[0046] When using the leakage cable characteristic monitoring data analysis module of the present embodiment, first connect the data acquisition interface 1 to the leakage cable monitoring device to be analyzed, turn on the power switch 8 to start the analysis module, and the data acquisition control board 3 collects and analyzes the leakage cable characteristic monitoring data of the leakage cable monitoring device; the indicator light 2 can indicate the working status of the leakage cable characteristic monitoring data analysis module. The leakage cable characteristic monitoring data analysis module integrates a lithium battery board 4, which is charged through the charging interface 5. The entire leakage cable characteristic monitoring data analysis module does not require an external power supply, is small in size and light in weight, and is convenient for engineers to carry and use when going out.

[0047] In addition, the utility model is also provided with an optical fiber connector 7 as an expansion interface of the leaky cable characteristic monitoring data analysis module. The optical fiber connector 7 is an SC type optical fiber connector, model SC / UPC, which is used to receive optical signal data of the leaky cable monitoring device.

[0048] Example 2

[0049] like Figure 2 As shown, it is a structural principle diagram of the data acquisition control board of this embodiment. The data acquisition control board includes a power conversion and management module, a PLL control module, an ADC sampling module, and an MCU processor which are connected in sequence.

[0050] The power conversion and management module is used to convert the voltage of the lithium battery panel into a suitable working voltage for the PLL control module;

[0051] The PLL control module is used to generate an intermediate frequency signal and output the intermediate frequency signal to the ADC sampling module;

[0052] The ADC sampling module is used to sample the intermediate frequency signal to obtain leakage cable characteristic monitoring data, and input the leakage cable characteristic monitoring data into the MCU processor;

[0053] The MCU processor is used to sort, sort, classify and categorize the leaky cable characteristic monitoring data;

[0054] When the data acquisition control board is working, the PLL control module sends a test signal to test the leaky cable, processes the received echo signal and sends it to the ADC sampling module. The ADC sampling module samples the data and sends it to the MCU for analysis and processing, and outputs a csv format file to a computer or other terminal device as a basis for engineering personnel to maintain and manage the leaky cable monitoring equipment.

[0055] Example 3

[0056] like Figure 3 As shown, it is a structural principle diagram of the PLL control module of this embodiment, and the PLL control module includes: a PLL sweep frequency source, a power divider, a first amplifier, a second amplifier, a third amplifier, a circulator, a mixer, and a low-pass filter; the PLL sweep frequency source is connected to the power divider, the power divider is respectively connected to the first amplifier and the second amplifier, the second amplifier is connected to the circulator, the circulator is connected to the third amplifier, the second amplifier and the third amplifier are connected to the mixer, and the mixer is connected to the low-pass filter.

[0057] The RF test signal generated by the PLL sweep source is divided into two paths by the power divider. One path is adjusted to the maximum possible output power (≤10dBm) by the first amplifier, and then output after passing through the circulator as a test signal to test whether the signal of the leaky cable is normal. The other path is used as a self-mixing local oscillator signal. After being amplified to 10dBm±2dbm by the second amplifier, it is input into the local oscillator input end of the mixer as the local oscillator signal of the mixer. The echo signal received by the circulator is amplified by the third amplifier and mixed with the local oscillator signal output by the mixer. After mixing, it is low-pass anti-aliasing filtered to obtain an intermediate frequency signal for sampling by the subsequent ADC sampling module.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
