[0044] Figure 5 1 is a flow chart of a test method for testing a composite sensor for testing temperature and pressure provided by an exemplary embodiment of the present application. The test method for testing a composite sensor for testing temperature and pressure is applicable to any of the composite sensors for testing temperature and pressure described above; Figure 5 As shown, the test method of the composite sensor for testing temperature and pressure includes the following steps: Step 510: Calculate the center position of the measured pipeline.

[0045] When the composite sensor is used to measure the measured pipeline, the center position of the measured pipeline is first calculated, such as the center position of the measured pipeline filled with gas or liquid, or the middle position of the liquid depth of the measured pipeline not filled with liquid. The central position of the measured pipeline is calculated to determine the measurement point that can more accurately reflect the temperature and pressure of the measured pipeline.

[0046] Step 520: Push the test probe to the center of the tested pipeline, and test the temperature and pressure of the center of the tested pipeline.

[0047] After determining the center position of the measured pipeline, the present application controls the power motor to drive the test probe to the center position of the measured pipeline to test the temperature and pressure values ​​of the center position, thereby achieving measurement of the measured pipeline.

[0048] The present application provides a testing method for a composite sensor for testing temperature and pressure, which comprises setting a filling head connection part, a test probe, a telescopic rod, a temperature-pressure integrated transmitter and a wireless transmitter; wherein the filling head connection part is used to connect to the tested pipeline, the test probe is connected to the filling head connection part, a temperature sensor and a pressure sensor are arranged on the test probe, and are respectively used to test the temperature value and pressure value in the tested pipeline, the telescopic rod is connected to the filling head connection part, the test probe is arranged at one end of the telescopic rod, the telescopic rod realizes that the test probe is away from or close to the filling head connection part through telescopic movement, the temperature-pressure integrated transmitter is connected to the temperature sensor and the pressure sensor, and is used to convert the temperature value and pressure value obtained by the temperature sensor and the pressure sensor into the wireless transmitter. The wireless transmitter is connected to the temperature and pressure integrated transmitter for transmitting the transmittable signal; that is, the temperature sensor and the pressure sensor are synchronously arranged on the test probe to realize the synchronous measurement of temperature and pressure, so as to obtain data with synchronous measurement time, and the temperature and pressure integrated transmitter and the wireless transmitter are used to realize wireless transmission of the measurement results, so as to realize measurement under complex conditions such as narrow space, and after the center position of the measured pipeline is calculated, the telescopic rod can be used to adjust the test probe and the temperature sensor and pressure sensor thereon to the center position in real time according to the measurement requirements, so as to realize the adjustment of different test points to meet the measurement under various environmental conditions, thereby improving the measurement accuracy.

[0049] In one embodiment, the specific implementation method of the above step 510 may be: obtaining the outer diameter of the measured pipe; controlling the movement of the telescopic rod until the test probe reaches the inner wall of the measured pipe, and measuring the movement distance of the telescopic rod; and calculating the center position of the measured pipe based on the outer diameter of the measured pipe and the movement distance of the telescopic rod.

[0050] If the outer diameter d and wall thickness d0 of the measured pipe are known, such as Figure 6 As shown, the present application directly controls the movement of the telescopic rod to push the test probe to (d / 2-d0), that is, the test probe reaches the center position of the tested pipeline.

[0051] If the outer diameter d of the measured pipe is known, but the wall thickness d0 is unknown, such as Figure 7As shown, the present application controls the movement of the telescopic rod until the test probe reaches the inner wall of the measured pipe, and measures the movement distance of the telescopic rod to obtain d1, then the wall thickness of the measured pipe d0=d-d1, and the center position of the measured pipe is (d1-d / 2), that is, the telescopic rod is controlled to move to push the test probe to (d1-d / 2), that is, the test probe reaches the center position of the measured pipe.

[0052] In one embodiment, the testing method of the above-mentioned composite sensor for testing temperature and pressure may also include: calibrating the temperature sensor and the pressure sensor with each other based on the temperature value and pressure value at the center position of the measured pipeline; if the calibration passes, determining the temperature value and pressure value at the center position of the measured pipeline as the temperature value and pressure value of the measured pipeline.

[0053] After measuring the temperature and pressure values ​​at the center of the measured pipeline, the present application calibrates the temperature and pressure values ​​to further determine the accuracy of the measurement results. Specifically, under the condition that the ratio of gas or liquid in a certain space remains unchanged, there is a certain relationship between the temperature and pressure. The present application uses the following formula to calibrate the measured temperature and pressure values: ； in, V is the volume, T is the measured temperature value, R.A. 2 、B 2 、C 2 、A 3 、A 4 、B 4 、B 5 are all set constants, b is the characteristic constant of the material in the measured pipeline, Tr It is the critical constant inherent to the material in the measured pipeline.

[0054] If the measured pressure value P And the above formula calculated P 1 is less than the preset value, it means that the measured temperature value and pressure value meet the corresponding relationship; if the measured pressure value P And the above formula calculated P 1 is greater than or equal to the preset value, it means that the measured temperature value and pressure value do not satisfy the corresponding relationship, that is, at least one of the measured temperature value and pressure value is abnormal.

[0057] Optionally, the present application performs measurements at multiple locations on the same measured pipeline and uses multiple measurement results for mutual verification to eliminate the problem of inaccurate measurement results caused by abnormalities of individual sensors. After the verification is qualified (that is, the measurement results of all composite sensors are generally consistent), the measurement results of all compliant sensors are weighted averaged to obtain the final measurement result.
