Description

Technical Field

[0001] The utility model relates to a wide voltage power supply real-time online wall thickness monitoring device, which is used for online monitoring of surface process wall thickness during exploration testing and completion flowback, and belongs to the field of oil and natural gas exploration and development. Background Art

[0002] During oil and gas exploration and production, corrosion or erosion can cause pipeline walls to thin, significantly reducing their reliability. Thinning pipeline walls increase the risk of leaks. To address this issue, a device that monitors wall thickness in real time is needed to provide an early warning.

[0003] Existing thickness measuring devices are mainly handheld. Handheld pipe wall thickness monitors use ultrasonic detection technology to measure the pipe wall thickness by emitting ultrasonic waves and receiving echo signals. The main problems are:

[0004] 1. Insufficient continuous monitoring capabilities: These systems are typically used for periodic inspections or emergency testing, and are not capable of continuous, real-time monitoring. Operators must regularly visit the site for measurements, making it impossible to obtain dynamic information on changes in pipe wall thickness.

[0005] 2. Insufficient data continuity and integrity: Due to intermittent measurement, the acquired data has time gaps, making it difficult to capture instantaneous changes in pipe wall thickness, and it is easy to miss key change trends or signs of early damage.

[0006] 3. High dependence on manual labor: It depends on the experience and technical level of the operator. The accuracy and consistency of the measurement results will be affected by the operation mode and environmental factors.

[0007] 4. Slow response speed: Due to the need for manual operation, the detection frequency is low, the time to discover the problem will be delayed, and it is impossible to provide timely warning in the early stage of pipeline problems.

[0008] 5. The application range of battery power supply is limited and the adaptability of the device power supply is insufficient: the unstable power supply voltage of the offshore mobile platform will cause damage to the device due to power supply problems, resulting in a high failure rate. Summary of the Invention

[0009] In view of the above problems, the purpose of the present invention is to provide a real-time online thickness measurement monitoring device with wide voltage power supply, which can operate normally within a wide voltage range and realize automatic and continuous data collection of pipeline wall thickness.

[0010] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0014] The wall thickness sensor management circuit is used to collect the process pipeline wall thickness data in real time;

[0015] The signal processing circuit is used to filter and integrate the collected wall thickness data and then send it to the system control center;

[0016] The system control center transmits the processed data to the computer terminal in real time via the RS485 communication circuit.

[0017] Furthermore, the wide voltage power management circuit includes a DCDC step-down circuit and an LDO step-down circuit;

[0018] The DCDC step-down circuit is used to step down the 7-40VDC direct current to 5.0V for powering the RS485 communication circuit;

[0019] The LDO step-down circuit is used to convert the 5.0V voltage into 3.3V to power the system control center, signal processing circuit, wall thickness sensor management circuit and human-computer interaction circuit.

[0020] Furthermore, the DCDC step-down circuit uses the LGS5145 chip as the main chip, and the LGS5145 chip has a total of 6 pins, the 1st pin is connected to one end of the first capacitor, the other end of the first capacitor is connected to the cathode of the diode, and the anode of the diode is grounded; the 2nd pin is grounded; the 3rd pin is connected to the resistance branch, the first resistor and the second resistor are connected in series on the resistance branch, and one end of the first resistor is connected to the 6th pin through the inductor; the 4th pin and the 5th pin are connected in parallel to the input voltage, and the second capacitor is connected in parallel with the ground; the 6th pin outputs a 5V power supply through the inductor.

[0021] Furthermore, the LDO step-down circuit uses the ME6210A33M3G chip as the main chip. The ME6210A33M3G chip has a total of 3 pins, and the first pin is grounded; the second pin is a 3.3V voltage output pin, and the third capacitor and the fourth capacitor are connected in parallel between the output voltage and the ground; the third pin is connected to the sixth pin of the LGS5145 chip, and the fifth capacitor is connected in parallel with the ground.
