Description

Technical Field

[0002] Test piles are used to detect pipeline potential and the effectiveness of system protection for large steel storage tanks, pipelines, and other metal structures. They automatically collect data and transmit it wirelessly. Test piles are typically installed outdoors in open areas. After long-term operation and exposure to sunlight, rain, lightning strikes, and other environmental factors, the parameters of the test pile's internal components change, causing the data automatically collected by the test pile to differ from the actual pipeline data. This results in poor data accuracy and can easily lead to pipeline safety risks. Therefore, test piles need to be inspected.

[0003] In the existing technology, pipeline maintenance personnel use a multimeter to measure the real data of the pipeline, and manually compare the measured real data with the data collected by the test pile to obtain the test results of the test pile. However, each test pile needs to be measured multiple times for different parameter contents, which makes the multimeter measurement workload large and the detection efficiency low. At the same time, the frequency of automatic data collection of the test pile is low, making it difficult for pipeline maintenance personnel to obtain real-time data, resulting in poor accuracy of the test pile detection results.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0047] With the continuous development of informatization, the application of cathodic protection test piles in pipeline cathodic protection is becoming more and more popular. The large-scale use of cathodic protection test piles enables the automatic collection and wireless remote transmission of cathodic protection parameters, without the need for manual on-site collection. However, cathodic protection test piles are usually installed outdoors. After long-term operation and environmental impact, the internal components of the cathodic protection test piles have experienced long-term natural environmental impacts, and their measurement accuracy is difficult to be continuously guaranteed. Therefore, after the cathodic protection test piles are put into field use, they need to be regularly tested for data validity. The detection efficiency of the multimeter is low, and the accuracy of the test results is poor, which can easily lead to misjudgment and cause unnecessary losses. Therefore, it is very necessary to conduct efficient and accurate detection of cathodic protection test piles.

[0048] In order to improve the detection efficiency and accuracy of the detection results of cathodic protection test piles, a detection device is provided in the solution of the present application. The following is an explanation of a detection device provided in an embodiment of the present application through a specific example. Figure 1 A schematic diagram of a detection device provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the detection device 100 includes: a control module 10 , an input module 20 , a signal simulation module 30 and a communication module 40 .

[0049] The control module 10 is connected to the input module 20 to receive detection instructions input through the input module 20. The input module 20 is mainly used for manual interaction. The detection personnel can input detection information through the input module 20. After receiving the detection information input by the user, the input module 20 sends the detection information to the control module 10 in the form of a detection instruction, so that the control module 10 receives and processes the detection instruction.

[0050] The control module 10 is also connected to the control terminal of the signal simulation module 30, and the output terminal of the signal simulation module 30 is connected to the data port of the pipeline cathodic protection test pile 50 to be tested, so as to control the signal simulation module 30 to generate and output a virtual pipeline protection signal with preset electrical parameters to the pipeline cathodic protection test pile 50 according to the test instructions. The test instructions may include preset electrical parameters, which can be preset electrical parameters input by the tester based on the attribute information of the pipeline cathodic protection test pile 50 to be tested. The preset electrical parameters can be numerical values. For example, the preset electrical parameters can be preset voltage values, preset current values, etc., and can also be other electrical parameters, which are not specifically limited in the embodiments of the present application.

[0051] After receiving the preset electrical parameters from the control module 10, the signal simulation module 30 generates a virtual pipeline protection signal with the preset electrical parameters based on the preset electrical parameters. The virtual pipeline protection signal generated by the signal simulation module 30 is an analog signal. Therefore, the output of the signal simulation module 30 is connected via a wire to the data port of the pipeline cathodic protection test station 50 to be tested, thereby transmitting the virtual pipeline protection signal with the preset electrical parameters to the pipeline cathodic protection test station 50 to be tested.

[0052] Optionally, the signal simulation module 30 may be an adjustable virtual signal generator.

[0053] Optionally, when the detection device 100 is connected to the pipeline cathodic protection test pile 50 to be detected, the detection personnel first disconnect the data port of the pipeline cathodic protection test pile 50 to be detected, and then connect the signal simulation module 30 in the detection device 100 through a wire.

[0054] The control module 10 is also connected to the debug port of the pipeline cathodic protection test pile 50 through the communication module 40 to obtain the collected electrical parameters of the virtual pipeline protection signal collected by the pipeline cathodic protection test pile 50, and to test the pipeline cathodic protection test pile 50 based on the preset electrical parameters and the collected electrical parameters. The communication connection between the control module 10 and the communication module 40 can be a wired communication connection or a wireless communication connection (such as a Bluetooth connection), which is not specifically limited in the embodiments of the present application.

[0055] After receiving the virtual pipeline protection signal with preset electrical parameters sent by the signal simulation module 30, the pipeline cathodic protection test pile 50 to be tested can perform analog-to-digital conversion based on the property values ​​of its internal components. Compensation coefficients for the analog-to-digital conversion are also stored within the pipeline cathodic protection test pile 50 to be tested. Based on the component property values ​​and the compensation coefficients, the collected electrical parameters corresponding to the virtual pipeline protection signal with preset electrical parameters can be acquired. The collected electrical parameters can be numerical values. The component property values ​​can be resistance values, capacitance values, etc.

[0056] In an embodiment of the present application, due to environmental influences, the property values ​​of the components within the pipeline cathodic protection test pile 50 to be tested will change, which will reduce the accuracy of the collected electrical parameters of the pipeline cathodic protection test pile 50 to be tested. Therefore, the effectiveness of the pipeline cathodic protection test pile to be tested can be detected by comparing the size of the preset electrical parameters and the collected electrical parameters.

[0057] Optionally, the input module 20 may be a touch display device. The inspector may input the inspection information through touch operation, and the touch display device may also be used to display data for the inspector to view.

[0058] Optionally, in this embodiment of the present application, the communication module 40 may be a serial communication module that transmits data bit by bit via data signal lines, ground lines, control lines, and the like. This communication method uses fewer data lines, saving communication costs in long-distance communications. The communication module 40 may include a built-in communication protocol for the pipeline cathodic protection test pile 50, thereby enabling real-time data reading and configuration from the pipeline cathodic protection test pile 50.

[0059] The detection device 100 may further include a power supply module 60, Figure 2 A schematic diagram of another detection device provided in an embodiment of the present application, such as Figure 2 As shown, the power module 60 is connected to the control module 10 to supply power to each module in the entire detection device 100 through the control module 10 .

[0060] Optionally, the detection device 100 may not include the power module 60. The detection personnel may first connect the output end of the signal simulation module 30 to the data port of the pipeline cathodic protection test pile 50 to be detected, and power each module in the detection device 100 through the pipeline cathodic protection test pile 50 to be detected, so that the detection device 100 is in working state.

[0061] The present application provides a detection device that can send a virtual pipeline protection signal with preset electrical parameters to the pipeline cathodic protection test pile to be detected, and then receive the collected electrical parameters of the virtual pipeline protection signal collected by the pipeline cathodic protection test pile according to the virtual pipeline protection signal with preset electrical parameters, and then automatically detect the pipeline cathodic protection test pile according to the preset electrical parameters and the collected electrical parameters. There is no need for manual data comparison, and the preset electrical parameters and the collected electrical parameters are both real-time data, which improves the timeliness and accuracy of the detection results. At the same time, the detection personnel only need to input the detection data corresponding to multiple detection items through the input module to view the corresponding detection results in the input module. Compared with the detection personnel measuring through a multimeter, the operation is simple and easy to carry, which reduces the workload and working time of the detection personnel and improves the detection efficiency.

[0062] In the above Figures 1 and 2 Based on the above embodiments, the present application also provides a detection method. Figure 3 This is a flow chart of a detection method provided in an embodiment of the present application. The execution subject of this method may be a control module in a detection device, and the control module may be a device with computing and processing functions, such as an MCU (Microcontroller Unit). Figure 3 As shown, the method includes:

[0063] S301: Receive a start detection instruction input through an input module.

[0064] For example, the inspector can click "Start Detection" in the input module through a touch operation, so that the control module receives the start detection instruction. The start detection instruction is used to instruct the inspection device to start inspecting the pipeline cathodic protection test pile.

[0065] Optionally, if the input module is provided with a hardware button for starting detection, the detection personnel can also press the "start detection" button so that the control module receives the start detection instruction corresponding to the "start detection" button.

[0066] S302: According to the start detection instruction, the signal simulation module is controlled to generate and output a virtual pipeline protection signal with preset electrical parameters to the pipeline cathodic protection test pile to be detected.

[0067] After the control module receives the start detection instruction, the control module can control the signal simulation module to start signal output.

[0068] The signal virtualization module can generate a virtual pipeline protection signal with preset electrical parameters, wherein the virtual protection signal can be an analog signal corresponding to the natural potential, an analog signal corresponding to the earth potential, an analog signal corresponding to the natural current, an analog signal corresponding to the earth current, etc. Of course, it can also be a virtual protection signal for cathodic protection of other pipelines to the ground, which is not specifically limited in the embodiments of the present application.

[0069] Optionally, the signal virtualization module can also generate a virtual pipeline interference signal with preset electrical parameters, and the pipeline cathodic protection test pile to be tested can also be tested through the interference signal.

[0070] Among them, if the virtual pipeline protection signal is an analog signal corresponding to the potential, the preset electrical parameter is a preset voltage value; if the virtual pipeline protection signal is an analog signal corresponding to the current, the preset electrical parameter is a preset current value.

[0071] The signal virtual module can convert the preset electrical parameters into corresponding analog signals through digital-to-analog conversion according to the preset electrical parameters, that is, the virtual pipeline protection signal of the preset electrical parameters, and send the virtual pipeline protection signal to the pipeline cathodic protection test pile to be tested so as to detect the pipeline cathodic protection test pile to be tested.

[0072] In an embodiment of the present application, the detection device can simulate the pipeline-to-ground cathodic protection and interference signals through the signal virtual module for the pipeline cathodic protection test pile to be detected to read.

[0073] S303: Acquire the collected electrical parameters of the virtual pipeline protection signal collected by the pipeline cathodic protection test pile and transmitted by the communication module.

[0074] After the pipeline cathodic protection test pile to be tested receives the virtual pipeline protection signal with preset electrical parameters, it can perform analog-to-digital conversion on the virtual pipeline protection signal based on the attribute values ​​of its internal components and the compensation coefficient to obtain the collected electrical parameters of the virtual pipeline protection signal by the pipeline cathodic protection test pile to be tested.

[0075] The communication module stores the communication protocol for the pipeline cathodic protection test pile to be tested, enabling real-time data transmission between the communication module and the test pile. After the test pile obtains the collected electrical parameters for the virtual pipeline protection signal, it transmits these collected electrical parameters to the communication module via a serial communication protocol. The communication module then feeds the collected electrical parameters back to the control module, allowing the control module to obtain the collected electrical parameters obtained by the communication module.

[0076] Optionally, after the signal virtual module starts to output a virtual pipeline protection signal with preset electrical parameters, after 1 second, the pipeline cathodic protection test pile to be tested performs analog-to-digital conversion to obtain the collected electrical parameters, and then the communication module is started to enable the communication module to obtain the collected electrical parameters.

[0077] S304: Testing the pipeline cathodic protection test pile according to the preset electrical parameters and the collected electrical parameters.

[0078] Compare the preset electrical parameters of the detection equipment with the data returned by the pipeline cathodic protection test pile to be tested, which is read through the serial port. If the collected electrical parameters returned by the pipeline cathodic protection test pile to be tested differ significantly from the preset electrical parameters, it indicates that the effectiveness of the pipeline cathodic protection test pile to be tested is low and the monitoring data is inaccurate. If the collected electrical parameters returned by the pipeline cathodic protection test pile to be tested differ little from the preset electrical parameters, it indicates that the pipeline cathodic protection test pile to be tested is effective, the monitoring data is accurate, and the monitoring is normal.

[0079] The test results can be displayed in the input module for the test personnel to view.

[0080] Optionally, the control module can also be connected to the server for communication. After receiving the preset electrical parameters and collected electrical parameters, the control module sends the preset electrical parameters and collected electrical parameters to the server, so that the server detects the pipeline cathodic protection test pile according to the preset electrical parameters and collected electrical parameters, obtains the detection results, and returns the detection results to the control module.

[0081] The present application provides a detection method, in which a control module receives a start detection instruction input through an input module, controls a signal simulation module to generate and output a virtual pipeline protection signal of preset electrical parameters to a pipeline cathodic protection test pile to be detected according to the start detection instruction, obtains the collected electrical parameters of the virtual pipeline protection signal collected by the pipeline cathodic protection test pile transmitted by the communication module, and automatically detects the pipeline cathodic protection test pile according to the preset electrical parameters and the collected electrical parameters, thereby realizing data collection and validity detection for the pipeline cathodic protection test pile in normal operation on site. Both the preset electrical parameters and the collected electrical parameters are real-time data, which improves the timeliness and accuracy of the detection results. At the same time, the detection personnel only need to input the detection data corresponding to multiple detection items through the input module to view the corresponding detection results in the input module. The operation is simple, which reduces the workload and working time of the detection personnel and improves the detection efficiency. In addition, the detection standards are unified, which ensures the consistency of the data monitoring performance of multiple pipeline cathodic protection test piles.

[0082] Furthermore, in the above Figure 3 Based on the detection method shown, the present application embodiment also provides another detection method. Optionally, Figure 4A flow chart of another detection method provided in the embodiment of the present application is shown as follows: Figure 4 As shown, before the above method S301, before receiving the start detection instruction input through the input module, it also includes:

[0083] S401: Receive configuration parameters input through an input module.

[0084] After powering on, the test equipment enters standby mode. In this state, the tester can use touch to click "Configure" in the input module to enter configuration parameters on the corresponding configuration page. Configuration parameters may include preset electrical parameters and communication configuration information for the pipeline cathodic protection test pile to be tested.

[0085] Optionally, the inspector may input corresponding configuration parameters based on the attribute information of the pipeline cathodic protection test pile to be inspected, wherein the attribute information may include the voltage range, current range, communication protocol, etc. of the pipeline cathodic protection test pile to be inspected.

[0086] Optionally, the communication configuration information may be 485 communication configuration information, or 232 communication configuration information. Of course, it may also be other communication configuration information, which is not specifically limited in the embodiments of the present application.

[0087] Optionally, if the input module is provided with a hardware button for configuration, the inspector may also press the "configure" button so that the control module receives the configuration parameters corresponding to the "configure" button.

[0088] S402: configuring the signal simulation module according to the configuration parameters, so that the signal simulation module generates and outputs a virtual pipeline protection signal with preset electrical parameters to the pipeline cathodic protection test pile according to the configuration parameters.

[0089] After receiving the configuration parameters, the control module can send the preset electrical parameters in the configuration parameters to the signal simulation module. The signal simulation module generates a corresponding virtual pipeline protection signal based on the preset electrical parameters in the received configuration parameters, and sends the virtual pipeline protection signal to the pipeline cathodic protection test pile to be tested.

[0090] Optionally, the control module can also send the communication configuration information in the configuration parameters to the communication module, so that the communication module can obtain the collected electrical parameters returned by the debugging interface of the pipeline cathodic protection test pile to be tested in real time through the serial port, and feed back the collected electrical parameters to the control module.

[0091] A detection method provided in an embodiment of the present application receives configuration parameters input through an input module, and configures a signal simulation module according to the configuration parameters, so that the signal simulation module generates and outputs a virtual pipeline protection signal with preset electrical parameters to the pipeline cathodic protection test pile according to the configuration parameters. The detection personnel can input a variety of different configuration parameters in the detection equipment, so that the detection equipment can perform detection of multiple different preset electrical parameters within the property range of the pipeline cathodic protection test pile, provide a full-scale adjustable signal source to the pipeline cathodic protection test pile, and can detect the accuracy of data collection of the pipeline cathodic protection test pile in each parameter segment. However, measurement through a multimeter can only detect a fixed signal source according to actual working conditions, and the detected signal is single, resulting in a small detection range. This method can increase the detection range and realize full-scale detection of the pipeline cathodic protection test pile.

[0092] Furthermore, in the above Figure 3 Based on the detection method shown, the present application embodiment also provides another detection method. Optionally, Figure 5 A flow chart of another detection method provided in the embodiment of the present application is shown as follows: Figure 5 As shown, the above method S304 detects the pipeline cathodic protection test pile according to the preset electrical parameters and the collected electrical parameters, including:

[0093] S501, calculating parameter errors between preset electrical parameters and collected electrical parameters.

[0094] The control module compares the preset electrical parameters with the collected electrical parameters and can calculate the parameter errors between the preset electrical parameters and the collected electrical parameters.

[0095] Optionally, the parameter error may be an average value of the difference between the preset electrical parameter and the collected electrical parameter. Of course, the parameter error may also be obtained by other calculation methods, which are not specifically limited in the embodiments of the present application.

[0096] S502: If the parameter error is greater than the preset error threshold, an alarm message is output.

[0097] For example, if the parameter error between the collected electrical parameters of the pipeline cathodic protection test pile to be tested and the preset electrical parameters is greater than the error threshold, that is, it is not within the prescribed allowable range, then the effectiveness of the pipeline cathodic protection test pile to be tested is low, the monitoring data is inaccurate, and an alarm message is obtained based on the parameter error, and the alarm message is output to the input module for the inspection personnel to view.

[0098] The error threshold can be set by the inspector through an input device. The alarm message may include information such as the preset electrical parameter values, the collected electrical parameter values, and the parameter error. The input module can also play the alarm message as a voice message, alerting the inspector that the effectiveness of the pipeline cathodic protection test pile under inspection is low.

[0099] When the parameter error is greater than the preset error threshold, the pipeline cathodic protection test pile to be tested can be calibrated, that is, the compensation coefficient in the pipeline cathodic protection test pile to be tested can be adjusted, and then the test can be performed again after adjustment to make the parameter error no greater than the preset error threshold, thereby making the pipeline cathodic protection test pile to be tested effective and improving the accuracy of its data monitoring.

[0100] Alternatively, this calibration may also be referred to as parameter compensation configuration.

[0101] Calibration of the pipeline cathodic protection test pile to be inspected can be performed by modifying the compensation coefficient within the pipeline cathodic protection test pile to be inspected. The inspector can view the alarm information displayed on the input module and determine the modified value of the compensation coefficient based on the alarm information. After inputting the modified value of the compensation coefficient into the input module, the control module receives the modified value of the compensation coefficient, transmits the modified value of the compensation coefficient through the communication module, and writes it to the pipeline cathodic protection test pile to be inspected, thereby modifying the compensation coefficient so that the parameter error between the collected electrical parameters of the pipeline cathodic protection test pile to be inspected based on the modified compensation coefficient and the preset electrical parameters is no greater than a preset error threshold.

[0102] Alternatively, if the compensation coefficients are modified multiple times, and the error between the collected electrical parameters obtained using the modified compensation coefficients and the preset electrical parameters is greater than a preset error threshold, the pipeline cathodic protection test pile to be tested has completely failed and cannot be corrected using the modified compensation coefficients. Optionally, the internal components of the pipeline cathodic protection test pile to be tested need to be replaced.

[0103] If the parameter error between the collected electrical parameters of the pipeline cathodic protection test pile to be tested and the preset electrical parameters is less than or equal to the preset error threshold, that is, within the prescribed allowable range, then the monitoring data of the pipeline cathodic protection test pile to be tested is relatively accurate and does not require correction. At this time, the preset electrical parameters and collected electrical parameters can be displayed in the input device for the inspection personnel to view and confirm.

[0104] A detection method provided in an embodiment of the present application calculates the parameter error between preset electrical parameters and collected electrical parameters. If the parameter error is greater than a preset error threshold, an alarm message is output to enable the detection personnel to calibrate the pipeline cathodic protection test pile to be detected. If the parameter error is less than or equal to the preset error threshold, the preset electrical parameters and the collected electrical parameters are displayed. Through this method, the measurement accuracy of the data of the pipeline cathodic protection test pile to be detected can be automatically judged. At the same time, the compensation coefficient of the pipeline cathodic protection test pile with low effectiveness can be adjusted and re-detected, thereby realizing the integrated detection and repair of the pipeline cathodic protection test pile. Through real-time and on-site detection and repair, the detection and repair efficiency of the pipeline cathodic protection test pile is improved. Compared with the prior art in which the detection personnel go to the site for detection and then go to the site again for repair after a period of time, in this method, the detection personnel can obtain the detection results in real time on-site through the detection equipment and then directly repair it on-site, thereby improving the repair efficiency of the detection personnel and reducing the labor cost when repairing the pipeline cathodic protection test pile, that is, reducing the repair cost of the pipeline cathodic protection test pile.

[0105] Furthermore, in the above Figure 3 Based on the detection method shown, the present application embodiment also provides another detection method. Optionally, Figure 6 A flow chart of another detection method provided in the embodiment of the present application is shown as follows: Figure 6 As shown, the method further includes:

[0106] S601, receiving a stop detection instruction input through an input module.

[0107] During normal testing, if the tester discovers a problem with the input configuration parameters, they can click "Stop Testing" in the input module at any time. The control module receives the stop test instruction, and the tester can modify the configuration parameters and restart the test. This stop test instruction instructs the tester to stop testing the pipeline cathodic protection test pile.

[0108] Optionally, after the inspector clicks "Start Detection" in the input module, the "Start Detection" can be converted to "Stop Detection".

[0109] Alternatively, if the input module is provided with a hardware button for stopping the test, the tester can also press the "stop test" button, so that the control module receives the stop test instruction corresponding to the "stop test" button. Optionally, the hardware button for stopping the test and the hardware button for starting the test can be the same hardware button.

[0110] S602: According to the stop detection instruction, the signal simulation module is controlled to stop generating the virtual pipeline protection signal to stop detecting the pipeline cathodic protection test pile.

[0111] After the control module receives the stop detection instruction from the input module, it controls the signal simulation module to stop generating the virtual pipeline protection signal according to the stop detection instruction, thereby causing the pipeline cathodic protection test pile to stop returning to collect electrical parameters and stop detecting the pipeline cathodic protection test pile.

[0112] A detection method provided in an embodiment of the present application receives a stop detection instruction input through an input module, and according to the stop detection instruction, controls the signal simulation module to stop generating a virtual pipeline protection signal to stop detecting the pipeline cathodic protection test pile, thereby improving the controllability of the detection process of the pipeline cathodic protection test pile.
