DETAILED DESCRIPTION

[0062] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0063] In some technologies, once the main control unit as the core component of the pipeline detector is damaged and fails, the entire pipeline detector cannot operate. In order to solve this technical problem, the present application provides a decentralized pipeline detection data acquisition system. The following describes the structure of each part of the decentralized pipeline detection data acquisition system:

[0064] For example, the electronic system of the pipeline detector generally consists of a data acquisition probe, a data collection unit, a main control unit, a battery pack and other components, which are connected in a reverse tree structure, such as Figure 4As shown, the detector adapts the corresponding number of data acquisition probes according to the size of the pipeline diameter. The data acquisition probes then transmit the collected data to the data collection unit in the form of cable connection in a group. The data collection unit then transmits the collected data to the main control unit through the cable, and the main control unit saves the data in the storage medium. As the diameter of the pipeline increases, there will be more and more data acquisition probes, and at the same time, there will be more and more cables connected to the data collection unit and the main control unit on the detector, which will cause difficulties in equipment assembly and replacement of components. The detector relies on high pressure to move forward in the pipeline. During the process of moving forward, there is a certain frequency and uncertain amplitude vibration, which is easy to cause the cable to fall off or the wire to be damaged, affecting the stability of data transmission. In the electronic system of the detector in the pipeline, the main control unit as the center of the system receives the power of the battery and powers the data collection unit and the probe, while collecting the data collected by the probe, and then storing the data in the storage medium. It can be seen that the main control unit plays a vital role in the system. Once the main control unit fails, each link in the system will not be able to operate, which adds hidden dangers to the actual use and operation of the equipment.

[0065] In response to the above problems, Figure 1 It can be seen that the present application provides a decentralized pipeline detection data acquisition system without a main control unit, which is applied to a pipeline detector, wherein the pipeline detector is provided with a cabin and a flange, and the flange is circumferentially distributed on the outside of the pipeline detector; the pipeline detector is generally applied to natural gas pipelines and oil pipelines, and the detection data of the pipeline to be tested is obtained by entering from the pipeline inlet to exiting from the pipeline outlet, and the detection data generally includes: magnetic leakage, stress, eddy current, and diameter measurement data; including: at least one data acquisition probe 1; a terminal device 3, wherein the terminal device 3 is connected to the data acquisition probe through a gateway 2, and the gateway 2 is an independent network connection device. Before the detector enters the pipe or after the detector exits the pipe, the data acquisition probe 1 is connected to the terminal device 3 through the gateway 2 for communication; the terminal device 3 is configured to send control instructions and download data instructions to the data acquisition probe 1; the data acquisition probe 1 is snap-connected to the flange, and the data acquisition probe 1 is configured to: according to the control instruction, obtain and store the detection data of the pipeline to be tested; according to the download data instruction, generate a data signal based on the detection data and send it to the terminal device 3.

[0066] The present application provides a decentralized pipeline detection data acquisition system without a main control unit, which introduces a decentralized mode into the pipeline detector. Each data acquisition probe 1 is used as a separate control unit, and the data acquisition probe 1 has functions such as data acquisition, data storage, wireless transmission and reception of Wi-Fi data, and wireless charging. Different numbers of data acquisition probes 1 can be placed according to the pipeline diameter in conjunction with the mechanical arm. Before the pipeline detector enters the pipeline to be tested, the terminal device 3 wakes up each data acquisition probe 1 wirelessly through the gateway 2. When the pipeline detector is running, each data acquisition probe 1 exists independently, and data is collected and stored in the pipeline detector. When the pipeline detector is out of the pipe, the terminal device 3 wirelessly connects all probes through Wi-Fi, downloads the collected data stored in the data acquisition probe 1, and completes the observation of the collected data of the pipeline to be tested. The present application omits the process of transmitting data to the main control unit during the operation of the pipeline detector, making the electronic system structure of the pipeline detector more concise, removing the cumbersome cable connection in the equipment, and making it more convenient to install or remove the data acquisition probe 1. In the present application, each data acquisition probe 1 is an independent individual. Even if an individual data acquisition probe 1 fails, it will not affect the data acquisition work of other data acquisition probes 1.

[0067] For example, currently the detector in the pipeline uses a wired cable to transmit the data collected by the data acquisition probe. The larger the diameter of the pipeline, the more data acquisition probes and data collection units are used, and the more cables are used in the detector. The present application can eliminate the need for a data collection unit, the setting of a main control unit, and the complex wiring cables in the detector, making assembly easier.

[0068] For example, the part set on the detector inside the pipeline only has a number of data acquisition probes 1. The data acquisition probes 1 are installed in a ring around the detector close to the inner wall of the pipeline to detect pipeline defects. Each probe exists independently without any cable connection. The probe circuit board is poured with epoxy resin and completely sealed in the probe box to adapt to the high pressure and oil, gas and other environments in the pipeline. Figure 1 The topology of the in-pipeline detector system is shown, and the number of data acquisition probes 1 is not limited to the number in the figure.

[0069] This application introduces the mode of Internet of Things networking into the pipeline detector. After the detector leaves the pipeline, the processing unit 12 of the data acquisition probe 1 adopts a wireless microcontroller with Wi-Fi function. It acts as a slave node to send the data collected by the data acquisition probe 1 in a wireless Wi-Fi manner. The processing unit 12 is equipped with a high-performance module compatible with the Wi-Fi 2.4GHz / 5GHz / 6GHz frequency band based on the 802.11ax protocol standard. After the device is finished running and leaves the pipeline, the user can use the terminal device 3 to communicate with the data acquisition probe 1 through the gateway 2 to view the detection data stored in the data acquisition probe 1. In the process of data transmission in this system, the data collected by the data acquisition probe 1 is directly transmitted to the terminal device 3, eliminating the process of data transmission to the collection unit, making the structure of the system simpler. Removing the cumbersome cable connection in the device, it is more convenient to install or remove the data acquisition probe 1. The user can connect the data acquisition probe 1 through the terminal device 3 to directly view the data in the detector, eliminating the process of device access debugging line and data download line debugging equipment or downloading data. This application can use Wi-Fi 6 technology to meet application requirements, and its maximum transmission rate can reach 3000Mbps (ie 375MB / s).

[0070] Depend on Figure 1 It can be seen that the data acquisition probe 1 includes: a sensor 11, the sensor 11 is configured to: obtain the detection data of the pipeline to be tested; a processing unit 12, the processing unit 12 is connected to the communication, and the processing unit 12 is configured to: generate a data signal based on the detection data; the processing unit 12 in this application uses an MCU with a Cortex_M3 core that integrates Wi-Fi radio frequency function and Wi-Fi baseband function, which can not only process the data from the sensor 11 in the data acquisition probe 1, but also can send the detection data through its own Wi-Fi function Sending to the terminal device 3; a sending unit 13, the sending unit 13 is communicatively connected with the processing unit 12, and the sending unit 13 is configured as follows: the sending unit 13 in the present application can be a PCB antenna, which reduces the occupied space of the sending unit 13 in the data acquisition probe 1; sending the data signal to the terminal device 3; a wireless charging circuit 14, the wireless charging circuit 14 is electrically connected with the sensor 11, the processing unit 12, and the sending unit 13, and the wireless charging circuit 14 is configured as follows: providing power to the sensor 11, the processing unit 12, and the sending unit 13.

[0071] Exemplarily, an MCU with a Cortex_M3 core and integrated Wi-Fi radio frequency function and Wi-Fi baseband function is selected as the control chip of the probe. It can not only process data from the sensor 11, but also send data to the receiving end through its own Wi-Fi function. In order to reduce space occupation, the Wi-Fi antenna is drawn with a PCB antenna. The data acquisition probe 1 is completely sealed and has a wireless interface-free design. It integrates a wireless charging coil 141 and a lithium battery 142 to make it rechargeable. A commercially available wireless charger is used to generate an alternating magnetic field, which forms a magnetic field coupling with the wireless charging coil 141 in the data acquisition probe 1. The charging coil 141 in the data acquisition probe 1 generates electrical energy, which is managed by a constant current source charging management circuit 143 to manage the charging and discharging of the lithium battery 142. Adding a memory unit 15 and a storage unit 16 can save the collected sensor data of different types.

[0072] Depend on Figure 2It can be seen that the wireless charging circuit 14 includes: a wireless charging coil 141, the wireless charging coil 141 is configured to: generate electric energy; a lithium battery 142, the lithium battery 142 is electrically connected to the wireless charging coil 141, and the lithium battery 142 is configured to: obtain electric energy for charging or power the sensor 11, the processing unit 12, and the sending unit 13; by using a wireless charger circulating on the market to generate an alternating magnetic field, a magnetic field coupling is formed with the wireless charging coil 141 in the data acquisition probe 1, and the wireless charging coil 141 in the data acquisition probe 1 generates electric energy, and the constant current source charging management circuit completes the charging of the lithium battery 142; the data acquisition probe 1 is charged outside the detector in the pipeline before installation; a charging management circuit 143, the charging management circuit 143 is connected to the lithium battery The battery 142 and the wireless charging coil 141 are electrically connected, and the charging management circuit 143 is configured to: adjust the charging current value of the lithium battery 142 according to the power of the lithium battery 142; through the charging management circuit 143, the current charged into the lithium battery 142 can be adjusted in real time according to the power of the lithium battery 142, so as to ensure the safety of the charging process of the lithium battery 142 and prevent the lithium battery 142 from being damaged due to excessive charging speed; the voltage conversion unit 144, the voltage conversion unit 144 is electrically connected to the lithium battery 142, the sensor 11, the processing unit 12, and the sending unit 13, and the voltage conversion unit 144 is configured to: convert the voltage value of the electric energy into a voltage value that can be received by the sensor 11, the processing unit 12, and the sending unit 13. The wireless charging coil 141 and the charging management circuit 143 constitute a wireless charging circuit, and the wireless charging circuit is connected to the lithium battery 142. The lithium battery 142 supplies power to the subsequent chips after passing through the DCDC power conversion unit 144. The control unit communicates with the charging management circuit to obtain the charging and discharging status and battery voltage of the lithium battery 142.

[0073] Exemplarily, when the mechanical structure of the in-pipe detector is ready, the data acquisition probes 1 are sequentially snapped onto the outside of the in-pipe detector, and a number of data acquisition probes 1 form a circular shape. Before the device enters the pipe, the terminal device 3 sends a control instruction to wake up all the data acquisition probes 1 and enter the detection state. After the detector is pushed into the pipeline, each data acquisition probe 1 works independently to collect pipeline data. These data are first saved in the memory, and after being processed by the processing unit 12, these data are saved in the storage module 16. When the device exits the pipe, the terminal device 3 is connected to all the data acquisition probes 1 on the in-pipe detector via the gateway 2, and the data in each data acquisition probe 1 can be downloaded for use by the debugger or user. When the device is not in use, the terminal device 3 controls all the data acquisition probes 1 to enter sleep mode, so that they enter a low power consumption state.

[0074] For example, Figure 4As shown, in the current pipeline detector, a disposable battery is used to supply power to the main control unit, and the main control unit supplies power to the data acquisition probe through the data collection unit. The charging method through the wireless charging circuit 14 in this application is compared with the current charging method through batteries and cables, which further realizes the wireless structure of the system. In addition, there is also a method in which the wireless charging process is set inside the device in the current pipeline detector, and wireless charging is realized by using the charging transmitting coil and receiving coil, but the transmitting coil is extended to the receiving coil in a wired form, which also causes the problem of complex wiring; and the induction coil directly supplies power to the data acquisition probe, without an energy storage link, and the fluctuation of the power supply voltage is likely to cause the problem of insufficient power supply. In this application, the data acquisition probe 1 is charged before use, and then installed on the flange for work, so as to realize the wireless structure of the entire device, and at the same time ensure that the data acquisition probe 1 has sufficient power, thereby ensuring the reliable operation of the pipeline detector during the detection process.

[0075] Depend on Figure 3 It can be seen that the data acquisition probe 1 also includes: a memory unit 15, the memory unit 15 is communicatively connected to the processing unit 12, and the memory unit 15 is configured to: pre-store the detection data; it can be understood that a large amount of data will be collected during the detection process of the pipeline detector, and the detection data cannot be stored in the storage unit 16 at the same time, so it is necessary to pre-store the detection data in the memory unit 15 first, and then gradually store it in the storage unit 16 through the memory unit 15; a storage unit 16, the storage unit 16 is communicatively connected to the processing unit 12, and the storage unit 16 is configured to: store the detection data.

[0076] In this embodiment, the baseband core 122 is also configured to: obtain the detection data in the storage unit 16; convert the detection data into a data signal with a frequency of one of 2.4GHz, 5GHz, and 6GHz, and send the converted data signal to the RF core 121; the RF core 121 is also configured to: amplify the signal strength of the data signal and send it. In the system, the RF core 121 and the baseband core 122 are used together to complete the wireless transmission of the data signal. The RF core is responsible for the transmission and reception of data. When receiving data, the RF core 121 can synthesize the above frequency and pass it to the baseband core 122. When sending data, the RF core 121 will amplify the data power processed by the baseband core 122 and send it out, that is, the RF signal, wherein the frequency band that the terminal device 3 can receive includes one of 2.4GHz, 5GHz and 6GHz. The baseband core 122 is responsible for modulating or demodulating the data, and can modulate the detection data in the processing unit 12 into the frequency required by the receiving device. For example, if the receiving device can only receive data signals with a frequency of 2.4 GHz, the frequency of the data will be modulated to 2.4 GHz and sent to the receiving device, or the received data will be demodulated into data that can be recognized by the processing unit 12.

[0077] Depend on Figure 1 It can be seen that the system further includes: the terminal device 3 is configured to: receive the data signal; generate and display the detection data based on the data signal. Figure 4 As shown, after the system runs through the pipeline, a large amount of data will be generated. The data is generally exported in the form of USB2.0, USB3.0, and Gigabit Ethernet ports. In actual tests, it is found that the speeds of reading data are 25MB / s, 90MB / s, and 100MB / s respectively. Assuming that 10TB of data is exported at 100MB / s, it takes about 29.12 hours, which is very time-consuming and occupies computer hard disk resources. The terminal device 3 can use a high-speed 6GHz Wi-Fi theoretical reading speed of 375MB / s, wherein the export time of the data stored in the data acquisition probe 1 using 6GHz Wi-Fi is about 7.4 hours.

[0078] Exemplarily, the terminal device 3 and the data acquisition probe 1 can be connected via Wi-Fi 2.4G, Wi-Fi 5G, or Wi-Fi 6G; when the terminal device 3 and the data acquisition probe 1 are connected via Wi-Fi 2.4G, the data acquisition probe 1 can convert the data information into a data signal in the 2.4GHz frequency band and send it to the terminal device 3; when the terminal device 3 and the data acquisition probe 1 are connected via Wi-Fi 5G, the data acquisition probe 1 can convert the data information into a data signal in the 5GHz frequency band and send it to the terminal device 3; when the terminal device 3 and the data acquisition probe 1 are connected via Wi-Fi 6G, the data acquisition probe 1 can convert the data information into a data signal in the 6GHz frequency band and send it to the terminal device 3.

[0079] In this embodiment, the terminal device 3 is communicatively connected with the data acquisition probe 1; the terminal device 3 is also configured to: display the power of the data acquisition probe 1 and debug the data acquisition probe 1 and the data acquisition probe 1. The terminal device 3 can check the power of the data acquisition probe 1 and debug it through Wi-Fi. The Wi-Fi function can wirelessly check the power of the data acquisition probe 1 and debug the probe function of the data acquisition probe 1 and the gateway 2. By checking the power of the data acquisition probe 1, the data acquisition probe 1 can be accurately charged before entering the pipeline to be tested for detection; and the terminal device 3 can be used to wirelessly debug the acquisition probe 1 and the gateway 2, and detect the performance of the data acquisition probe 1 and the gateway 2 before entering the pipeline and whether they are operating normally, thereby ensuring the normal operation of the data acquisition probe 1 and the gateway 2, and improving the debugging efficiency of the data acquisition probe 1 and the gateway 2.

[0080] Exemplarily, the decentralized in-pipeline detection data acquisition system of the present application consists of four parts: a data acquisition probe 1, a wireless charger for the probe, a gateway 2, and a terminal device 3 used by the user. The data acquisition probe 1 is charged outside the device before installation. The terminal device 3 connects to the data acquisition probe 1 via the gateway 2 via Wi-Fi. The gateway 2 automatically assigns an address to each data acquisition probe 1. The data acquisition probes 1 need to be arranged in a circular order, and the debugger can manually assign probe addresses. Terminal devices 3 such as computers, mobile phones, and handheld devices can send operating instructions to the data acquisition probe 1, wake up the data acquisition probe 1, check the power of the data acquisition probe 1, download data, etc.

[0081] In this embodiment, the sensor 11, the processing unit 12, the sending unit 13, and the wireless charging circuit 14 are sealed in the data acquisition probe 1 by epoxy resin. The circuit board, namely the sensor 11, the processing unit 12, the sending unit 13, and the wireless charging circuit 14 are poured with epoxy resin and completely sealed in the data acquisition probe 1 to adapt to the high pressure in the pipeline and the environment of oil, gas, water, etc. The epoxy resin has the function of preventing oil, gas, and water. It can be understood that the decentralized pipeline detection data acquisition system provided by the present application is applied to natural gas pipelines, oil pipelines, etc. The above measures can prevent substances such as oil, gas, and water from entering the data acquisition probe 1 and damaging the components inside the data acquisition probe 1. And it can achieve the effect of pressure resistance and shock resistance, and improve the reliability of data acquisition.

[0082] In this embodiment, the gateway 2 can communicate with 1 to 2007 data acquisition probes 1. According to the 802.11ax (i.e. Wi-Fi 6) protocol, the AID (i.e. address identification number) ranges from 1 to 2007, so the system can theoretically connect up to 2007 probes. The maximum number of 2007 probes can fully meet the requirements of multi-channel, high-precision and even ultra-high-precision in-pipe detectors, and can be applied to pipelines of any length. The system can place a corresponding number of data acquisition probes 1 according to different calibers of detection equipment.

[0083] The present application provides a decentralized in-pipeline detection data acquisition system without a master control unit, which has the following advantages:

[0084] In the pipeline detector, there is no centralized pipeline detector electronic system topology structure. Each data acquisition probe 1 exists independently. According to different caliber detectors, a corresponding number of data acquisition probes 1 can be placed, which greatly reduces the complexity of the equipment structure, is cable-free, and is easy to assemble; users do not need to use wired methods to debug and download data, and use wireless Wi-Fi to directly debug and download data to the device. The debugging and downloading data methods are not limited to Wi-Fi, including wireless transmission technology derived later; the data acquisition probe 1 is based on the microprocessor MCU with Wi-Fi function and peripheral devices, and integrates eMMC storage chip, wireless charging coil, charging management circuit and energy storage lithium battery, and is sealed to form a probe that can be wirelessly charged and wirelessly send and receive data. The probe uses different sensors to realize all information used by pipeline detectors such as leakage magnetic field, diameter measurement, stress, and mileage wheel. The probe adopts overall sealing treatment, which is pressure-resistant and shock-resistant, and improves the reliability of data acquisition.
