Description

Technical Field

[0001] The present invention relates to the technical field of pressure vessel strength testing, and in particular to a testing device, system, method and storage medium. Background Art

[0002] As a key pressure-bearing equipment, the safety of pressure vessels must be guaranteed by strength tests required by regulations. Although water pressure testing is a commonly used method, air pressure testing must be used for containers that need to be kept dry or highly clean. Traditional manual valve group testing relies on manual operation of valve switching and parameter adjustment, which has problems such as low efficiency, poor safety and high work intensity. In particular, the efficiency is further affected by the significant differences in test chamber parameters. Existing automatic testing systems use pneumatic proportional valves, PLC control and other technologies, but they are prone to loss of control when the leakage rate of the tested container is too high, and cannot monitor the sealing performance and degree of damage in real time.

[0003] Therefore, there is an urgent need to develop a new air pressure testing system that is efficient and safe, can monitor sealing and evaluate damage in real time, and meet the industry's high reliability requirements. Summary of the Invention

[0004] The present invention aims to address the problems of existing testing systems. It provides a testing device, a testing system, a computer storage medium, and a program product that can improve the efficiency and safety of pressure vessel air pressure testing, instantly detect abnormalities during the testing process, and qualitatively analyze potential damage within the tested vessel.

[0005] To solve the above technical problems, an embodiment of the present invention discloses a testing device, including a first air inlet channel, wherein the air inlet of the first air inlet channel is connected to an external air supply device, and the air outlet of the first air inlet channel is connected to a test container, and along the air inlet direction, a mass flow meter, a first pneumatic valve and an electric valve are sequentially arranged on the first air inlet channel; a first pressure sensor, wherein the first pressure sensor is arranged in the first air inlet channel, and along the air inlet direction, the first pressure sensor is located between the electric valve and the air outlet of the first air inlet channel; an exhaust channel, wherein the air inlet of the exhaust channel is connected to the test container, and a second pneumatic valve is arranged on the exhaust channel; a second pressure sensor, wherein the second pressure sensor is arranged in the exhaust channel, and along the air outlet direction, the second pressure sensor is located between the second pneumatic valve and the air inlet of the exhaust channel.

[0006] Using the above technical solution, the test device of the present application embodiment can automatically increase and decrease pressure through the first pneumatic valve, the electric valve, and the second pneumatic valve.

Combined with the pressure-mass curve during the test, it can provide key data (for example, a pressure-mass curve or a pressure-time curve) for accident analysis (for example, strength failure of the test container), and can predict the damage of the tested equipment (for example, the test container) and the feasibility of repair.

[0035] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0036] Figure 1 According to some embodiments of the present application, a structural diagram of a test system is shown. Figure 1 . Figure 2 According to some embodiments of the present application, a structural diagram of a test system is shown. Figure 2 .

[0037] like Figure 1 and Figure 2 As shown, a test system 1 provided in an embodiment of the present application includes: a test device 10, a gas supply device 20, a test container 30, and a controller 40. By way of example, the controller 40 in the embodiment of the present application is a programmable logic controller (PLC controller). The test safety gas provided by the gas supply device 20 in the embodiment of the present application may specifically be nitrogen, but is not limited thereto. In actual application, other safety gases commonly used by those skilled in the art for testing may also be used, which are not further limited herein, such as helium.

[0038] The test device 10 provided in the embodiment of the present application includes: a first air intake channel 11 , a first pressure sensor 12 , an exhaust channel 13 and a second pressure sensor 14 .

[0039] Specifically, if Figure 1 As shown, the test container 30 is connected to the first air inlet channel 11 and the exhaust channel 13. That is, the air outlet 1101 of the first air inlet channel 11 is connected to the test container 30, and the air inlet 1301 of the exhaust channel 13 is connected to the test container 30. Exemplarily, the test container 30 is provided with a quick interface (not shown in the figure) adapted to the air outlet 1101 of the first air inlet channel 11 and the air inlet 1301 of the exhaust channel 13, so that the test device 10 of the embodiment of the present application can be quickly disassembled and assembled with the test container 30, thereby improving the test efficiency. The air inlet 1102 of the first air inlet channel 11 is connected to the external air supply device 20 loaded with the safety gas for detection, and the air inlet 1102 is connected to the external air supply device 20 along the air inlet direction (such as Figure 1 As shown in the X direction, the first air intake channel 11 is provided with a mass flow meter 111, a first pneumatic valve 112 and an electric valve 113 in sequence, and the exhaust channel 13 is provided with a second pneumatic valve 131.

[0040] Thus, by rapidly opening or closing the first pneumatic valve 112 and the electric valve 113, the pressure within the first air inlet channel 11 and the test container 30 can be precisely controlled during the inflation process. In other words, during the inflation process, air from the external air supply device 20 flows into the first air inlet channel 11 through the air inlet 1102 of the first air inlet channel 11, then sequentially flows through the mass flowmeter 111, the first pneumatic valve 112, and the electric valve 113, and then flows into the test container 30 through the air outlet 1101 of the first air inlet channel 11, completing the inflation process.

[0041] Furthermore, by rapidly opening or closing the second pneumatic valve 131, the pressure within the test container 30 and the exhaust channel 13 can be precisely controlled during the exhaust process. In other words, during the exhaust process, the gas within the test container 30 flows into the exhaust channel 13 through the air inlet 1301 of the exhaust channel 13, flows through the second pneumatic valve 131, and then flows out through the air outlet 1302 of the exhaust channel 13, completing the exhaust process.

[0042] The testing device 10 of the present embodiment utilizes the first pneumatic valve 112, the electric valve 113, and the second pneumatic valve 131 to automatically increase and decrease pressure. Compared to the manual pressure increase and decrease methods used in the prior art, the testing device 10 of the present embodiment offers improved pressure accuracy and greater applicability, particularly for accurately and safely meeting the requirements for testing small containers and low-pressure cavities. This improves worker efficiency and workload, eliminating potential safety risks associated with manual valve adjustment.

[0043] In addition, the testing device 10 of the embodiment of the present application detects the mass of the gas flowing through it through the mass flow meter 111, and judges the abnormality of the equipment based on the relationship between the measurement value mass (i.e., the mass of the gas flowing through) detected by the mass flow meter 111 and the pressure at the outlet of the test container 30 (for example, the pressure value P detected by the second pressure sensor 14), so as to provide key data (for example, a pressure-mass curve or a pressure-time curve) for accident analysis (for example, strength failure of the test container 30), and can predict the damage of the tested equipment (for example, the test container 30) and the feasibility of repair.

[0044] It can be understood that according to the ideal gas state equation: PV=nRT, where P represents the pressure of the gas (unit: Pascal, Pa), that is, the pressure value detected by the second pressure sensor 14, and V represents the volume of the gas (unit: cubic meter, m 3 ), n represents the amount of gas (unit: mole, mol), R represents the ideal gas constant (its value is approximately 8.314 J / (mol·K)), and T represents the absolute temperature of the gas (unit: Kelvin, K). Thus, during the test process, based on the measured value mass (i.e., the mass of the gas flowing through) detected by the mass flowmeter 111 of the embodiment of the present application, and the real-time measured pressure value at the outlet of the test container 30 (e.g., the pressure value P measured by the second pressure sensor 14 described later, i.e., the gas pressure P in the ideal gas state equation), the amount of gas flowing through the first air inlet passage 11 and into the test container 30 can be determined.

[0045] Furthermore, since the volume of the device under test (e.g., the test container 30) is determined, by comparing the size relationship between the amount of gas and the volume of the device under test, it is possible to determine whether there are abnormal conditions such as bulging or leakage in the test device 10 and the test container 30 of the embodiment of the present application, and to determine the size of the potential affected area, so as to provide a basis for further accident analysis.

[0046] Continue to refer Figure 1 、 2, the above-mentioned controller 40 is electrically connected to the mass flow meter 111, the first pneumatic valve 112, the electric valve 113 and the first pressure sensor 12 provided on the first air intake channel 11, and the second pneumatic valve 131 and the second pressure sensor 14 provided on the exhaust channel 13. The first pressure sensor 12 is provided in the first air intake channel 11, along the air intake direction X, the first pressure sensor 12 is located between the electric valve 113 and the air outlet 1101 of the first air intake channel 11, and is used to detect the pressure value in the first air intake channel 11 and feed it back to the controller 40. During the inflation process, the mass flow meter 111 detects the measured value mass (i.e., the mass of the gas flowing through) in real time, and feeds it back to the controller 40 for calculating the relationship between the measured value and the amount of gas. The second pressure sensor 14 is provided in the exhaust channel 13, along the air outlet direction (such as Figure 1 The second pressure sensor 14 is located between the second pneumatic valve 131 and the air inlet 1301 of the exhaust channel 13, and is used to detect the pressure value of the test container 30 and feed it back to the controller 40.

[0047] The controller 40 is configured to control the opening and closing of the first pneumatic valve 112 and the electric valve 113 based on an input control program, the measured value mass detected and fed back by the mass flowmeter 111, and the pressure value P detected and fed back by the second pressure sensor 14, thereby automatically pressurizing the test container 30. Furthermore, the controller 40 is configured to control the opening and closing of the second pneumatic valve 131 based on an input control program and the pressure value fed back by the second pressure sensor 14, thereby automatically depressurizing the test container 30.

[0048] Exemplarily, the first pneumatic valve 112, the second pneumatic valve 131 and the electric valve 113 of the embodiment of the present application all have a position feedback function to feed back their own position signals to the controller 40, so that the test system 1 of the embodiment of the present application can better monitor the status of the first pneumatic valve 112, the second pneumatic valve 131 and the electric valve 113, thereby improving the safety of the test system 1.

[0049] For example, in some possible implementations, Figure 2 As shown, the test system 1 of the embodiment of the present application further includes a human-computer interaction device 50. The human-computer interaction device 50 is electrically connected to the controller 40 and is used to input at least control programs, control parameters, and display status parameters. For example, the measured value mass detected and fed back by the mass flowmeter 111, the pressure value P0 detected and fed back by the first pressure sensor 12, the pressure value P detected and fed back by the second pressure sensor 14, and their position status, etc.

[0050] Thus, the input of control programs and control parameters and the display of status parameters are realized through the human-computer interaction device 50, so that the testing device 10 of the embodiment of the present application can perform automatic pressure increase and pressure reduction operations on the test container 30 according to the user-defined control program, avoiding manual adjustment of the valve that does not meet the test accuracy requirements of the small container and low pressure cavity, which brings safety risks. At the same time, it greatly reduces the interference of human factors and improves the accuracy and efficiency of detection.

[0051] For example, the human-computer interaction device 50 of the embodiment of the present application includes a touch screen 51 and an industrial computer 52 (see Figure 2 ), in actual application, the selection can be made based on actual needs, and no further specific limitations are given here. The human-computer interaction device 50 of the embodiment of the present application can also store and display execution parameter records of the controller 40. Storing and displaying execution parameter records by the human-computer interaction device 50 greatly improves the traceability of test data, facilitating subsequent detailed analysis, such as the accident analysis described above.

[0052] For example, in some possible implementations, Figure 2 As shown, the test system 1 of the embodiment of the present application further includes an alarm 60. The alarm 60 is electrically connected to the controller 40. When the controller 40 performs an abnormal operation of inflating or deflating the test container 30 according to the control program, the controller 40 controls the alarm 60 to trigger an alarm prompt (for example, an audible or visual alarm, or displaying the alarm content on the touch screen 51 and the industrial computer 52), so that the operator can make timely adjustments to the test device 10 of the embodiment of the present application.

[0053] In addition, during the test process, in order to cope with the situation where the automated step-up and step-down operations cannot be performed normally, for example, when an abnormality such as a power outage occurs, the test device 10 of the embodiment of the present application also has a manual test function, which provides great operational flexibility.

[0054] Continue to refer Figure 1 For example, in some possible implementations, the testing device 10 of the embodiment of the present application further includes a second air inlet channel 15. Specifically, along the air inlet direction X, the air inlet 1501 of the second air inlet channel 15 is located between the first pneumatic valve 112 and the air inlet 1102 of the first air inlet channel 11, and the air outlet 1502 of the second air inlet channel 15 is located between the electric valve 113 and the test container 30. The second air inlet channel 15 is arranged in parallel with the first air inlet channel 11, and a bypass valve 151 is provided on the second air inlet channel 15. When an abnormality occurs in the first pneumatic valve 112 and the electric valve 113 on the first air inlet channel 11 of the embodiment of the present application, the bypass valve 151 on the second air inlet channel 15 can be operated to perform a manual test using the second air inlet channel 15.

[0055] For example, the bypass valve 151 in the embodiment of the present application includes a first bypass valve 1511 and a second bypass valve 1512. The first bypass valve 1511 and the second bypass valve 1512 are sequentially arranged in the second intake passage 15 along the intake direction X. The first bypass valve 1511 is a manual ball valve, and the second bypass valve 1512 is a manual stop valve. During manual testing, the first bypass valve 1511 is first operated to open and close, and then the second bypass valve 1512 is operated to precisely adjust the amount of gas flowing in the second intake passage 15.

[0056] For example, in some possible implementations, a first manual valve 114 is further provided on the first air inlet channel 11 of the embodiment of the present application. Along the air inlet direction X, the first manual valve 114 is located between the air inlet 1501 of the second air inlet channel 15 and the mass flowmeter 111. The first manual valve 114 is a manual ball valve. When an abnormality occurs in the first pneumatic valve 112 and the electric valve 113 on the first air inlet channel 11 of the embodiment of the present application, the air source can be shut off in an emergency by manually operating the first manual valve 114, thereby protecting subsequent equipment of the testing device 10 of the embodiment of the present application.

[0057] For example, in some possible implementations, an exhaust branch 16 is further provided on the exhaust channel 13 of the embodiment of the present application. Specifically, along the exhaust direction Y, the second pneumatic valve 131 is located between the air inlet 1601 and the air outlet 1602 of the exhaust branch 16. The exhaust branch 16 is arranged in parallel with the exhaust channel 13, and a second manual valve 161 is provided on the exhaust branch 16. The second manual valve 161 is a manual ball valve. In the event of an abnormality in the second pneumatic valve 131 on the exhaust channel 13 of the embodiment of the present application, the second manual valve 161 on the exhaust branch 16 can be operated to perform emergency exhaust and manual testing using the exhaust branch 16.

[0058] For example, in some possible implementations, the test device 10 of the present application embodiment further includes a first pressure gauge 181, a second pressure gauge 182, and a third pressure gauge 183 for manually reading the air pressure in the test device 10 and the test container 30. Figure 1As shown, a first pressure gauge 181 is provided in the first air inlet channel 11, located along the air inlet direction X between the air inlet 1102 of the first air inlet channel 11 and the air inlet 1501 of the second air inlet channel 15, for manual reading of the air pressure at the point where the air source (i.e., the air supply device 20) enters the first air inlet channel 11. A second pressure gauge 182 is provided in the first air inlet channel 11, located along the air inlet direction X between the electric valve 113 and the air outlet 1101 of the first air inlet channel 11, for manual reading of the air pressure within the first air inlet channel 11 before entering the test container 30. A third pressure gauge 183 is provided in the exhaust channel 13, located along the air outlet direction Y between the air inlet 1301 of the exhaust channel 13 and the second pressure sensor 14, for manual reading of the air pressure within the test container 30.

[0059] For example, the embodiments of the present application do not impose any specific restrictions on the locations of the first pressure gauge 181, the second pressure gauge 182, and the third pressure gauge 183, as long as they can achieve, for example, measuring the air pressure at the point where the air source enters the first air inlet channel 11 by the first pressure gauge 181, measuring the air pressure at the entrance of the test container 30 by the second pressure gauge 182, and measuring the air pressure within the test container 30 by the third pressure gauge 183. For example, in other possible embodiments, the first pressure gauge 181 and the second pressure gauge 182 can also be sequentially arranged at other locations on the first air inlet channel 11 along the air inlet direction X, and the third pressure gauge 183 can also be arranged at other locations on the exhaust channel 13.

[0060] For example, the embodiment of the present application does not limit the types of the first pneumatic valve 112 and the second pneumatic valve 131. The first pneumatic valve 112 and the second pneumatic valve 131 in the embodiment of the present application can specifically be pneumatic ball valves, but are not limited to this. In actual application, other valves commonly used by technical personnel in this field can also be used, and no further specific limitations are made here.

[0061] Furthermore, the embodiment of the present application does not limit the types of the first pressure sensor 12 and the second pressure sensor 14. The first pressure sensor 12 and the second pressure sensor 14 in the embodiment of the present application may specifically be pressure transmitters, but are not limited thereto. In actual applications, other sensors commonly used by those skilled in the art may also be used, and no further specific limitations are made here.

[0062] The following is based on Figure 1 and Figure 2 The schematic diagram of the test system 1 is shown in FIG. Figure 3A and Figure 3B The test method of this application is described in detail.

[0063] Specifically, this application Figure 3A and Figure 3BThe testing method can be implemented by the controller 40 of the testing system 1 executing relevant programs.

[0064] refer to Figure 3A According to a specific embodiment of the present application, the testing method provided includes the following steps.

[0065] S100: Obtaining an execution instruction of an input pre-execution control program.

[0066] Here, the controller 40 of the embodiment of the present application can accept execution instructions for pre-executed control programs and control parameters input from an external source (e.g., the aforementioned human-computer interaction device 50). Furthermore, the controller 40 can store and update the acquired execution parameter records, significantly improving the traceability of test data.

[0067] S200: According to the execution instruction, the controller performs a pressure charging operation on the test container.

[0068] Here, the controller 40 of the embodiment of the present application is electrically connected to the first pneumatic valve 112 and the electric valve 113 , and controls the opening and closing of the first pneumatic valve 112 and the electric valve 113 according to the execution instruction to realize the automatic pressure filling operation of the test container 30 .

[0069] It should be noted that when the testing device 10 of the embodiment of the present application is operating normally, the first manual valve 114 on the first air inlet channel 11 of the embodiment of the present application is in an open state, the first bypass valve 1511 and the second bypass valve 1512 on the second air inlet channel 15, and the second manual valve 161 on the exhaust branch 16 are all in a closed state, so that the testing device 10 of the embodiment of the present application can automatically increase and decrease the pressure of the test container 30 through the first air inlet channel 11 and the exhaust channel 13.

[0070] Continue to refer Figure 3A In the embodiment of the present application, step S200 specifically includes:

[0071] S201: Control the first pneumatic valve to open, and determine that the first pneumatic valve is in an open state.

[0072] Here, the controller 40 of the embodiment of the present application sends an electrical signal to the first pneumatic valve 112 to open the first pneumatic valve 112 according to the execution instruction, and receives the position signal (for example, the open state signal and the closed state signal) fed back after the first pneumatic valve 112 is opened to determine that the first pneumatic valve 112 is in the open state.

[0073] S202: Control the electric valve to open and determine that the electric valve is in an open state, and adjust the opening angle of the electric valve according to the real-time pressure value calculated based on the measurement value mass detected by the mass flow meter and the volume V of the test container.

[0074] Here, the controller 40 of the embodiment of the present application sends an electrical signal to the electric valve 113 to open the electric valve 113 according to the execution instruction, and receives a position signal (for example, a valve angle signal) fed back after the electric valve 113 is opened to determine that the electric valve 113 is in an open state, and can also determine the opening angle of the electric valve 113.

[0075] Therefore, in combination with the ideal gas state equation (PV=nRT), the controller 40 calculates the real-time pressure value based on the measured value mass detected in real time by the mass flowmeter 111, the volume V of the test container 30, and the molar mass and molar constant of the safety gas used for testing (for example, nitrogen), and then compares the real-time pressure value with the planned pressure value for boosting (i.e., the planned pressure value for the inflation process of the test device 10 in the embodiment of the present application), and sends an electrical signal to the electric valve 113 for adjusting the opening angle of the electric valve 113, so as to adjust the opening angle of the electric valve 113 in real time to maintain the instantaneous pressure boosting speed in accordance with the set pressure boosting speed.

[0076] For example, when the calculated real-time pressure value is greater than the boost plan pressure value, the controller 40 sends an electrical signal to the electric valve 113 according to the execution instruction to reduce the opening angle of the electric valve 113; or, when the calculated real-time pressure value is less than the boost plan pressure value, the controller 40 sends an electrical signal to the electric valve 113 according to the execution instruction to increase the opening angle of the electric valve 113.

[0077] S203: Draw a pressure-mass curve diagram according to the measurement value mass detected by the mass flow meter and the pressure value P detected by the second pressure sensor.

[0078] Here, the controller 40 of the embodiment of the present application draws a pressure-mass curve (see Figure 3C In some possible implementations, the pressure-mass curve drawn by the controller 40 can be displayed on the human-computer interaction device 50 .

[0079] Figure 3C Schematic diagram of pressure-mass curve of the embodiment of the present application is shown. Figure 3C As shown in the figure, the horizontal axis (mass / kg) represents the measurement value mass detected by the mass flowmeter 111, and the vertical axis (pressure / Pascal) represents the pressure value P detected by the second pressure sensor 14. As can be seen from the figure, there is a clear linear relationship between the measurement value mass detected by the mass flowmeter 111 and the pressure value P detected by the second pressure sensor 14 in the embodiment of the present application. As the mass of the test safety gas flowing in increases, the pressure in the test container 30 also increases.

[0080] That is to say, combined Figure 3CIt is verified that the test system 1 of the embodiment of the present application can achieve coordinated dual measurement through the mass flow meter 111 and the second pressure sensor 14 to ensure more accurate test results.

[0081] S204: Determine whether the pressure value P detected by the second pressure sensor is equal to the first preset pressure value P1, control the first pneumatic valve to close, and control the electric valve to close after a preset time.

[0082] Here, the controller 40 of the embodiment of the present application determines whether to close the first pneumatic valve 112 based on the relationship between the pressure value P detected by the second pressure sensor 14 and the first preset pressure value P1. For example, the first preset pressure value P1 = 70 bar.

[0083] For example, when the pressure value P detected by the second pressure sensor 14 is equal to the first preset pressure value P1, that is, P=70bar=P1, the controller 40 sends an electrical signal to the first pneumatic valve 112 to close the first pneumatic valve 112 according to the execution instruction, and after a preset time (for example, 3S), the controller 40 sends an electrical signal to the electric valve 113 to close the electric valve 113 according to the execution instruction.

[0084] Alternatively, when the pressure value P detected by the second pressure sensor 14 is less than the first preset pressure value P1, ie, P=65 bar<P1, the controller 40 does not send a closing electrical signal to the first pneumatic valve 112 and the electric valve 113 according to the execution instruction.

[0085] refer to Figure 3B The testing method of the embodiment of the present application also includes step S300.

[0086] S300: According to the execution instruction, the controller performs a pressure relief operation on the test container.

[0087] Here, the controller 40 of the embodiment of the present application is electrically connected to the second pneumatic valve 131 and controls the opening and closing of the second pneumatic valve 131 according to an execution instruction to achieve an automatic pressure relief operation on the test container 30 .

[0088] Continue to refer Figure 3B In the embodiment of the present application, step S300 specifically includes:

[0089] S301: Control the second pneumatic valve to open, and determine that the second pneumatic valve is in an open state.

[0090] Here, the controller 40 of the embodiment of the present application sends an electrical signal to the second pneumatic valve 131 to open the second pneumatic valve 131 according to the execution instruction, and receives the position signal (for example, the open state signal and the closed state signal) fed back after the second pneumatic valve 131 is opened to determine that the second pneumatic valve 131 is in the open state.

[0091] S302: Determine that the pressure value P detected by the second pressure sensor is equal to a third preset pressure value P3, and control the second pneumatic valve to close.

[0092] Here, the controller 40 of the embodiment of the present application receives the pressure value P detected by the second pressure sensor 14 according to the execution instruction, and determines whether to close the second pneumatic valve 131 based on the relationship between the pressure value and the third preset pressure value P3. For example, the third preset pressure value P3 = 0 bar.

[0093] For example, when the pressure value P detected by the second pressure sensor 14 is equal to the third preset pressure value P3, that is, P=0 bar=P3, the controller 40 sends an electrical signal to the second pneumatic valve 131 to close the second pneumatic valve 131 according to the execution instruction.

[0094] Alternatively, when the pressure value P detected by the second pressure sensor 14 is greater than the third preset pressure value P3, ie, P=5 bar>P3, the controller 40 does not send a closing electrical signal to the second pneumatic valve 131 according to the execution instruction.

[0095] In addition, the testing method of the embodiment of the present application further includes step S400:

[0096] S400: Determine that the test system is in an abnormal state, control the alarm to sound, and control the first pneumatic valve and the electric valve to close.

[0097] Here, the controller 40 of the embodiment of the present application determines whether the test system is in an abnormal state based on the status signal of the first pneumatic valve 112 (for example, the open status signal and the closed status signal) and the position information of the electric valve 113 (for example, the valve angle signal), as well as the measurement value mass detected by the mass flowmeter 111, the pressure value P0 detected by the first pressure sensor 12 and the pressure value P detected by the second pressure sensor 14.

[0098] Specifically, determining that the test system is in an abnormal state at least includes:

[0099] When the mass flowmeter 111 detects an increase in mass flow, the pressure value P0 detected by the first pressure sensor 12 remains unchanged within a preset time (e.g., 5 seconds). Alternatively, the pressure value P detected by the second pressure sensor 14 remains unchanged within a preset time (e.g., 3 seconds). Specifically, if the first pressure sensor 12 or the second pressure sensor 14 detects no change in pressure within the preset time or the pressure value is too low, the controller 40 can determine that the test system 1 (e.g., the test device 10 and the test container 30) of the present embodiment is in an abnormal state.

[0100] Alternatively, the difference between the pressure value P0 detected by the first pressure sensor 12 and the pressure value P detected by the second pressure sensor 14 is greater than the second preset pressure value P2. For example, the second preset pressure value P2 = 10 bar. For example, if the difference between the pressure value P0 detected by the first pressure sensor 12 and the pressure value P detected by the second pressure sensor 14 is 15 bar and is greater than P2, the controller 40 can determine that the test system 1 (e.g., the test device 10 and the test container 30) of the present embodiment is in an abnormal state.

[0101] Alternatively, the calculated value obtained based on the measured value mass of the mass flowmeter 111, the volume V of the test container 30, and the pressure value P detected by the second pressure sensor 14 is smaller than the theoretical value. Here, the calculated value = P × V / mass, where P represents the gas pressure (unit: Pascal, Pa), that is, the pressure value detected by the second pressure sensor 14, and V represents the volume of the test container 30 (unit: cubic meter, m 3 ), mass represents the mass of the gas (unit: kilogram, kg), which is also the value measured by the mass flowmeter 111. Specifically, when the product of the pressure value P detected by the second pressure sensor 14 and the volume V of the test container 30 divided by the value mass measured by the mass flowmeter 111 is less than the theoretical value, the controller 40 can determine that the test system 1 (e.g., the test device 10 and the test container 30) of the embodiment of the present application is in an abnormal state.

[0102] It can be understood that when the test medium (i.e. the test safety gas) is determined, , where R specific is the specific gas constant. Therefore, when the type of gas provided by the gas supply device 20 (e.g., nitrogen) is determined and the volume V of the test container is determined, the changes in the pressure value P detected by the second pressure sensor 14 and the measured value mass (i.e., the mass of the inflowing gas) detected by the mass flowmeter 111 in the test system 1 of the embodiment of the present application can be fully reflected in the calculation formula P×V / mass.

[0103] Furthermore, through the dual measurement of the coordinated cooperation of the mass flow meter 111 and the pressure sensor (for example, the first pressure sensor 12 and the second pressure sensor 14 mentioned above), the test results of the test system 1 of the embodiment of the present application are more accurate, and the dual protection of the mass flow meter 111 and the pressure sensor can detect various abnormal situations in a timely manner, thereby ensuring the safety of the test system 1 of the embodiment of the present application.

[0104] Alternatively, the controller 40 receives a power-off signal fed back by the first pressure sensor 12. Alternatively, the controller 40 receives a power-off signal fed back by the second pressure sensor 14. It is understood that the normal output signal range of a pressure sensor is 4-20 mA, while the output signal of a pressure sensor when it is powered off is 0 mA. When the controller 40 receives a power-off signal of 0 mA, it can determine that the test system 1 according to the embodiment of the present application is in an abnormal state.

[0105] Based on this, when the test system 1 of the embodiment of the present application is in an abnormal state, the controller 40 of the embodiment of the present application sends an alarm electrical signal to the alarm 60 according to the execution instruction, and the controller 40 controls the alarm 60 to alarm.

[0106] However, the embodiment of the present application does not limit the conditions for the controller 40 to determine whether the test system 1 is in an abnormal state. For example, in other possible implementations, since the first pneumatic valve 112, the second pneumatic valve 131 and the electric valve 113 in the embodiment of the present application all have a position feedback function to feed back their own position signals to the controller 40, when the controller 40 receives abnormal position information (for example, not closed normally, not opened normally, or the valve is opened at the wrong angle) fed back by any one of the first pneumatic valve 112, the second pneumatic valve 131 and the electric valve 113, the controller 40 can also determine that the test system 1 in the embodiment of the present application is in an abnormal state.
