Description

Technical Field

[0001] The present invention relates to the technical field of tower scanning, in particular to a novel digital tower scanning data acquisition system. Background Art

[0002] Tower scanning technology uses the attenuation of gamma rays after they pass through the object to reveal internal physical information, such as density, and thereby infer the object's internal conditions. Tower scanning technology offers rapid detection and high sensitivity, making it a preferred choice for nondestructive testing of process equipment in chemical plants. It uses gamma rays to scan the tower longitudinally. Based on the intensity of the received gamma rays, the tower scanning data acquisition system converts the received radiation signal into a digital signal. This signal is then displayed on a data terminal, resulting in the density distribution within the tower, allowing for the detection of anomalies within the tower.

[0003] Existing tower scanning systems generally include a data acquisition and processing system, a lifting device, and a measuring device. As the core component of a tower scanning device, the tower scanning data acquisition and processing system requires digital applications suitable for modern measurement, as well as more precise data acquisition and conversion methods. Typically, chemical plants are densely populated with equipment and pipelines, and towers are all of considerable height. Conventional data acquisition devices are generally wired. During measurement, a gamma-ray emitter and a gamma-ray detector are placed on either side of the tower being measured. These two devices maintain the same height and distance, moving up and down synchronously at equal intervals. During this movement, the intensity of the gamma rays after penetrating the material within the tower is measured. However, in some cases, the operating site is complex and pipelines are numerous. Wired measurement increases the difficulty of data acquisition and is inconvenient for online operation. Furthermore, certain measurement environments, such as chemical plants, require explosion-proof electronic equipment, but current tower scanning data acquisition systems lack such protection.

[0022] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] The novel digital tower scanning data acquisition system of the present invention will be described below with reference to the accompanying drawings. Figure 1 This is a schematic diagram of the structure of the new digital tower scanning data acquisition system provided by the present invention. Figure 1 As shown, the new digital tower scanning data acquisition system specifically includes: data collector, power supply system, and X-ray scanning system remote terminal computer.

[0024] The X-ray scanning system includes a gamma detector and a gamma output device, which are typically located on either side of the device under test, at the same horizontal position. The gamma output device, acting as a gamma-ray radiation source, emits gamma-ray particles toward the device under test during data measurement. The gamma detector is equipped with a probe that receives gamma-ray particles that pass through the device under test. The probe is made of NaI crystal, which is low-power, low-cost, and suitable for field use. The gamma detector and gamma output device are connected to a data acquisition device via a connecting cable, ensuring that the X-ray scanning system can transmit scanned data to the data acquisition device during data measurement. The connecting cable is a data cable that can transmit both data and power. Therefore, when the data acquisition device is powered on, it also powers the X-ray scanning system. The device under test can be chemical plant equipment, such as manufacturing and process equipment in the petrochemical industry.

[0025] The power supply system is connected to the data collector via a power cord, which provides power to the data collector. The data collector communicates with the remote terminal computer via Bluetooth. The remote terminal computer can be a terminal display device such as a PDA or tablet computer. It uses the Windows operating system, offering low power consumption and fast startup and shutdown. The remote terminal computer can remotely control the X-ray scanning system to initiate data measurements. Then, via Bluetooth remote communication, it can access scan data collected from the data collector in real time. It also features explosion-proof features, meeting explosion-proof requirements in measurement environments such as chemical plants.

[0026] In an embodiment of the present invention, the X-ray scanning system is connected to a data collector to achieve data measurement and collection, and the data collector is then connected to a remote terminal computer via Bluetooth to achieve remote data collection and acquisition, thereby facilitating on-site operations and ensuring the accuracy of the measurement and collection process. This can meet the explosion-proof requirements for electronic equipment in measurement environments such as chemical plants and ensure the safety of on-site operations.

[0027] Furthermore, the data acquisition system includes a signal input / output board and a signal processing mainboard. The signal input / output board is used to acquire scanning data from the device under test (DUT) from the probe in the X-ray scanning system. Specifically, the gamma detector receives gamma-ray particles passing through the DUT and transmits the corresponding scanning data to the signal input / output board of the data acquisition system. The signal input / output board is primarily responsible for probe signal input, data signal shaping, counting, and signal output. The signal input / output board counts the scanning data and transmits the scan data count signal to the signal processing mainboard.

[0028] The signal processing motherboard is responsible for storing the input signal, performing analog-to-digital conversion, and performing wireless communication such as Bluetooth. Here, the signal processing motherboard is used to digitally convert the counting signal into a corresponding digital signal, and then send the digital signal to a remote terminal computer via Bluetooth to complete remote data collection.

[0029] The data collector designed in the embodiment of the present invention can acquire scanning data from the probe in real time and perform signal processing, and then transmit the processed digital signal to a remote terminal computer via Bluetooth. The on-site operation process is convenient and ensures the accuracy of the measurement and acquisition process.

[0030] Furthermore, the power supply system includes a lithium cobalt oxide battery, a charger, and a power board. The lithium cobalt oxide battery provides power to the data acquisition unit and X-ray scanning system, ensuring normal operation of the equipment. Its high energy density ensures explosion-proof safety. The power board manages the output and charging of the lithium cobalt oxide battery, controlling the charger to charge the lithium cobalt oxide battery and preventing abnormal conditions such as overcharging, short circuiting, and power shortages, which could affect the data acquisition process of the data acquisition unit and X-ray scanning system.

[0031] In some embodiments, the novel digital tower scanning data acquisition system also includes an automatic calibration module. This is because when performing gamma-ray scanning, the gamma detector and gamma output must be at the same horizontal position to ensure that the gamma rays fully scan the device under test. However, when the device under test is located in complex and harsh testing environments, it is difficult to maintain the same horizontal position for the gamma detector and gamma output. Therefore, embodiments of the present invention include an automatic calibration module in the novel digital tower scanning data acquisition system. This module monitors the horizontal position of the gamma detector and gamma output and calculates the difference between their horizontal positions.

[0032] When the horizontal position difference is greater than the preset position error, the horizontal position is automatically corrected so that the horizontal position difference after automatic correction is less than or equal to the position error. The position error can be preset based on the conditions met in the actual environment or historical experience.

[0033] In this embodiment of the present invention, an automatic correction module monitors the horizontal position of the gamma detector and gamma output in real time. Using the position error as a threshold, the module determines whether the horizontal positions of the gamma detector and gamma output meet measurement conditions, thereby achieving automatic horizontal position correction. This ensures that gamma ray scanning proceeds normally and accurately captures scan data, even in complex and harsh testing environments.

[0034] In some embodiments, the remote terminal computer is equipped with data acquisition software, which is used to control the measurement parameters of the radiographic scanning system. The remote terminal computer uses the data acquisition software to remotely control the measurement and acquisition process of the data collector of the radiographic scanning system. The data acquisition software includes a control panel, which allows the measurement parameters of the radiographic scanning system to be set. The radiographic scanning system then performs data measurements according to the measurement parameters.

[0035] The measurement parameters include at least one of the following: measurement mode, measurement duration, measurement step length, starting height, dead time, and a selected channel of a gamma detector.

[0036] In the control panel of the data acquisition software, these measurement parameters are set one by one and saved, and then the data acquisition startup function is turned on. In this way, the X-ray scanning system data collector can start to perform data measurement and acquisition according to the set measurement parameters.

[0037] In an embodiment of the present invention, measurement parameters are set and a data acquisition startup function is run in the data acquisition software deployed on the remote terminal computer to remotely control the measurement and acquisition of the data acquisition device of the X-ray scanning system. This eliminates the need for manual close-range adjustment of the data acquisition device, facilitates operation, and ensures the safety of on-site operations.

[0038] Furthermore, on the control panel of the data acquisition software, the measurement parameters of the ray scanning system during the ray scanning process can be reasonably set. Figure 2 Let’s introduce them one by one.

[0039] The measurement methods include automatic measurement and manual measurement, such as Figure 2 As shown in (a), the entire data acquisition system can be set to either automatic or manual measurement mode. Under normal test conditions, both within a chemical plant and in the field, automatic measurement can be used, eliminating the need for manual operation. However, under certain special test conditions, manual operation of the acquisition system is required.

[0040] The measurement duration is the measurement time of a single measurement point of the ray scanning system, such as Figure 2 As shown in (b), the gamma detector and gamma output device of the X-ray scanning system will gradually descend to each measurement point according to the measurement step length during the scanning process. The measurement time at each measurement point is the measurement time of a single measurement point.

[0041] The measurement step length is the unit descent height of the ray scanning system, e.g. Figure 2 As shown in (c), the X-ray scanning system descends from the top of the device under test (DUT) in a fixed step length. Specifically, each time the X-ray scanning system descends one unit of height, it measures the DUT and acquires scan data within the measurement duration. This unit of height is the measurement step length, which can be adjusted appropriately based on the height of the DUT and actual site conditions.

[0042] The starting height is the height at which the ray scanning system begins to descend, such as Figure 2 As shown in (d), when performing measurements, the starting height of the ray scanning system needs to be set according to the height of the device under test, that is, the horizontal position height of the gamma detector and the gamma output device before measurement.

[0043] Dead time is the interval time between the detection of adjacent gamma ray particles by the gamma detector in the ray scanning system, and the unit is microseconds (us). The ray scanning system receives gamma ray particles through the probe of the gamma detector. However, after detecting a gamma ray particle or photon event, the gamma detector cannot respond to new events for a period of time, that is, receive the next gamma ray particle or photon event. This period of time is the interval time between the detection of adjacent gamma ray particles by the gamma detector, which is called dead time. The dead time is set as follows: Figure 2 As shown in (e), the existence of dead time will cause the actual recorded counting rate to be lower than the actual incident particle speed under high technology rate conditions, so correction is made by setting the dead time.

[0044] The selection channel of the gamma detector includes selecting the number of gamma detectors that perform data measurement in the ray scanning system. During the ray scanning process of the ray scanning system, there can be multiple gamma detectors, all of which can simultaneously receive the gamma rays emitted by the gamma output device through the detector, which can avoid the situation where a single gamma detector failure causes the measurement process to fail. Figure 2 As shown in (f), the detector selection can be performed by setting the selection channel of the γ detector. Taking two γ detectors as an example, one or two detector channels can be selected to perform data measurement. The unselected γ detector channels do not work during data measurement.

[0045] The following example illustrates the acquisition process of the new digital tower scanning data acquisition system. A radiographic scanning measurement is performed on a specific device under test at a refinery. For example, the device under test is a butterfly valve, and the process medium is vacuum residue. Possible damage to the butterfly valve causes the valve opening to differ from the actual flow rate. However, due to a maintenance shutdown, all subsequent process sections will be shut down. To verify that the actual valve opening is consistent with the set opening, the new digital tower scanning data acquisition system is used to scan a cross-section of the valve section. During the measurement process, the power supply system is checked to ensure sufficient power is being used by the data acquisition device. The radiographic scanning system and the data acquisition device are then connected and turned on. Next, the data acquisition software is launched on the remote terminal computer. Measurement parameters such as the measurement mode, measurement duration, measurement step, starting height, dead time, and gamma detector channel selection are configured on the software's control panel. During measurement, the gamma detector and gamma output are aligned horizontally. The measurement is started on the remote terminal computer. The remote terminal computer and the data acquisition device are connected via Bluetooth. Measurements are performed within a 10-meter radius, and the data is automatically saved to the remote terminal computer after each measurement.

[0046] In the embodiment of the present invention, the control panel of the data acquisition software on the remote terminal computer can be used to reasonably set corresponding measurement parameters to execute the data measurement process before executing the data measurement, thereby realizing remote automated measurement of the device under test without the need for manual adjustment of the acquisition system, and having great convenience.

[0047] Considering that the tower scanning technology in the prior art can only calculate the surface density information of the fault of the device under test by detecting the strength of γ, it is impossible to simulate the equipment operation status of the device under test to control the equipment operation status of the device under test. Based on the above scenario, in some embodiments, the data acquisition software in the remote terminal computer has a built-in chemical equipment model of the device under test, and the chemical equipment model is used to simulate the operating status of the device under test online. Because in a specific actual environment, it is impossible to directly set up a new digital tower scanning data acquisition system for certain special devices under test for measurement, in response to this situation, the embodiment of the present invention realizes the process of online simulation measurement in the new digital tower scanning data acquisition system. First, for certain special devices under test that cannot be directly measured, it is necessary to pre-build the corresponding chemical equipment model and deploy it in the data acquisition software, specifically including distillation towers, vacuum towers, atmospheric towers, heat exchangers, valves, pipelines, etc. The online simulation process is introduced below.

[0048] First, obtain the measurement parameters of the ray scanning system and the device parameters of the device under test. First, it is still necessary to set the corresponding measurement parameters, that is, Figure 2 In addition to the various measurement parameters shown in , it is also necessary to obtain the device parameters of the device under test. These device parameters are generally the device parameters of the corresponding tower, including diameter, height, number of trays, medium in the tower, tray density, etc.

[0049] Next, the measurement parameters and equipment parameters are input into the chemical equipment model for fitting, and the density information diagram of the chemical equipment model is obtained. In addition, the plane diagram of the chemical equipment model can also be fitted. During the fitting process, data simulation is performed to simulate the chemical equipment model as the equipment under test. Then, according to the equipment parameters, the data acquisition device ray scanning system is still started to perform data acquisition, and remotely transmitted to the data acquisition software in the remote terminal computer. Finally, the density information diagram of the chemical equipment model is obtained in combination with the equipment parameters. The density information diagram is used to simulate the operating status of the equipment under test. For example, the density information diagram of the chemical equipment model of a certain equipment under test is as follows Figure 5 As shown, Figure 5 On the left is the equipment under test (DUT) simulated by the chemical equipment model, and in the center is the final measured tower structure of the DUT, including normal tray liquid holding, excessive tray liquid holding, mist entrainment, flooding, normal tray, foam, floor drain, insufficient tray liquid holding, normal tray, damaged tray, missing tray, and bottom liquid level. The scanning curve on the right is a two-dimensional data curve graph collected by the data logger and remotely transmitted to the remote terminal computer.

[0050] In an embodiment of the present invention, for certain devices under test that cannot be directly measured, these devices under test are simulated through chemical equipment models preset in data acquisition software, and the tower type of the device under test is measured in accordance with the normal data acquisition process in combination with the corresponding device parameters, thereby meeting the needs of more measurement scenarios.

[0051] In some embodiments, the data acquisition software is further configured with a terminal display module, which is used to visualize the digital signal transmitted by Bluetooth as a two-dimensional data curve graph. After data measurement and acquisition are completed, the data acquisition system transmits the corresponding digital signal to the remote terminal computer via the Bluetooth module. At this time, the data acquisition software can use the terminal display module to realize data visualization, and visualize the digital signal transmitted by Bluetooth as a two-dimensional data curve graph, such as Figure 4 As shown in the figure, the two-dimensional data curve is used to represent the final measurement results of the new digital tower scanning data acquisition system. The operating status of the device under test can be clearly understood from the figure. In addition, the two-dimensional data curve also marks some measurement parameters, which can clearly show the implementation process of measurement acquisition.

[0052] In addition, the terminal display module is also used to output digital signals and two-dimensional data curve graphs. Figure 5 As shown, the terminal display module is used to store digital signals and two-dimensional data curve graphs in a file. By opening the file, the corresponding digital signals and two-dimensional data curve graphs can be visualized. By exporting, the digital signals and two-dimensional data curve graphs can be output as data, for example, the data can be uniformly output in EXCEL format for transmission to other devices or terminals for downstream tasks.

[0053] The embodiment of the present invention realizes the visualization of collected data through the terminal display module of the data acquisition software, can clearly show the implementation process of measurement acquisition and the specific operating status of the device under test, and also realizes the data output function to facilitate the implementation of downstream tasks.

[0054] In some embodiments, the novel digital tower scanning data acquisition system further includes a portable integrated chassis, in which the data collector and power supply system are integrated. The portable integrated chassis has integrated packaging, transportation, and usage functions. The internal components of the data collector and power supply system are integrated into a single chassis. The chassis is compact and portable, convenient for on-site use and transportation, and has the advantages of being sturdy, safe, and durable, capable of adapting to some harsh on-site measurement environments. When performing data measurement, the X-ray scanning system is first connected to the portable integrated chassis via a connecting cable, and the portable integrated chassis is connected to a remote terminal computer via Bluetooth communication. The X-ray scanning system and the portable integrated chassis are then started, and the measurement parameters are set through the remote control computer. The portable integrated chassis and the X-ray scanning system are then controlled to perform data measurement.

[0055] In other embodiments, the portable integrated chassis is used to control the X-ray scanning system to perform data measurement when the remote terminal computer is disconnected, and to display the count signal of the scanned data through the data collector during data measurement. Under the influence of harsh measurement environments in certain construction projects, the remote terminal computer and the data collector may become disconnected, such as due to a Bluetooth connection failure, abnormal disconnection, or a sudden power outage or shutdown of the remote terminal computer, resulting in an interruption in the data collection process. In this case, the portable integrated chassis will control the X-ray scanning system to continue performing data measurement, ensuring that the data collection process is not interrupted, and will display the count signal of the scanned data through the data collector within the portable integrated chassis during data measurement. When the connection between the remote terminal computer and the portable integrated chassis is restored, the corresponding count signal is transmitted to the remote terminal computer through the portable integrated chassis, and the normal measurement and collection process is resumed.

[0056] In an embodiment of the present invention, a portable integrated chassis is used to solve the problem of disconnection of a remote terminal computer. When the measurement process is interrupted due to abnormal disconnection of the remote terminal computer, the portable integrated chassis is used to control the X-ray scanning system and the data collector to continue to perform data measurement and collection. This ensures that the measurement and collection process is not affected and the real-time nature of the collected data is guaranteed.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
