Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, apparatus, electronic device and storage medium for determining media mass flow rate. Background Technology

[0002] Mass flow meters are widely used for controlling and measuring the flow rate of media in various fields. Especially in the nuclear power industry, gas mass flow meters are widely used for gas flow control and measurement. However, in existing technologies, when determining the mass flow rate of a medium using a mass flow meter, the measurement results are subject to error due to changes in the medium's temperature, leading to inaccurate determination of the mass flow rate and thus poor adaptability of the mass flow meter to different operating conditions.

[0003] For example, a constant temperature differential gas mass flow meter is equipped with a platinum resistance sensor for measuring the temperature of the medium and a platinum resistance sensor for measuring the flow rate of the medium. The temperature difference between the platinum resistance sensor for measuring the temperature of the medium and the platinum resistance sensor for measuring the flow rate of the medium is adjusted to a constant temperature difference through a hardware Wheatstone bridge.

[0004] In a constant-temperature differential thermal gas mass flow meter, the mass flow rate of the medium and the heat carried away by the medium through the thermal sensor satisfy King's Law. Where ΔT is the temperature difference between the platinum resistance sensor measuring the medium temperature and the platinum resistance sensor measuring the medium flow rate, P is the heat carried away by the medium as it flows through the thermal sensor, and q m K1 and K2 are the mass flow rates of the medium. K1 and K2 depend on the sensor geometry and gas properties, such as thermal conductivity, viscosity and specific heat capacity. K3 is related to the Reynolds number.

[0005] However, the thermal conductivity, viscosity, specific heat capacity, and density of a fluid are related to the medium temperature. When the medium temperature changes significantly, k1, k2, and k3 will change accordingly, leading to a large error in the flow meter's measurement results. Furthermore, as can be seen from the Wheatstone regulating circuit, when the ambient temperature rises, the speed-sensing resistance increases. To maintain the balance of the Wheatstone measuring bridge, its heating power will change with the temperature increase, and the mass flow rate measured by the flow meter will also change. Therefore, it can be seen that even when the wind speed remains constant and only the medium temperature changes, the flow meter's measurement results will still be inaccurate. Summary of the Invention

[0006] This invention provides a method, apparatus, electronic device, and storage medium for determining the mass flow rate of a medium, which can accurately determine the mass flow rate of the medium, thereby improving the measurement accuracy and adaptability of the mass flow meter.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0036] Example 1

[0037] Figure 1 This is a flowchart of a method for determining the mass flow rate of a medium according to Embodiment 1 of the present invention. This embodiment is applicable to situations requiring accurate determination of the mass flow rate of a medium. The method can be executed by a medium mass flow rate determining device, which can be implemented through software and / or hardware, and is generally directly integrated into the electronic device executing this method. This electronic device can be a terminal device or a server device. The present invention does not limit the type of electronic device executing the medium mass flow rate determining method. Specifically, as shown... Figure 1As shown, the method for determining the mass flow rate of the medium may specifically include the following steps:

[0038] S110. Determine the current medium temperature corresponding to the medium whose mass flow rate is to be determined, and the power flow rate data corresponding to the medium whose mass flow rate is to be determined.

[0039] The medium whose mass flow rate needs to be determined can be any medium for which the mass flow rate needs to be determined. For example, the medium whose mass flow rate needs to be determined can be a gas, etc., and this embodiment of the invention does not impose any limitations on this. The current medium temperature can be the temperature of the medium at the time the mass flow rate is determined. The power-flow rate data can be data that characterizes the relationship between the medium's power and its flow rate. For example, the power-flow rate data can be power-flow rate curve data determined by the medium's power and flow rate, or power-flow rate list data determined by the medium's power and flow rate, etc., and this embodiment of the invention does not impose any limitations on this.

[0040] In this embodiment of the invention, the current medium temperature and power flow rate data corresponding to the medium whose mass flow rate is to be determined are determined. It is understood that the number of power flow rate data points can be one or more, and this embodiment of the invention does not limit this.

[0041] S120. Determine the target power flow rate data in the power flow rate data based on the current medium temperature.

[0042] The power flow target data can be the target data within the power flow data. It is understood that the number of power flow target data can be one or more, and this embodiment of the invention does not impose any limitation on this.

[0043] In this embodiment of the invention, after determining the current medium temperature and power flow rate data corresponding to the medium whose mass flow rate is to be determined, the target power flow rate data in the power flow rate data can be further determined based on the current medium temperature. It is understood that when there is only one power flow rate data point, the power flow rate data is the target power flow rate data, and the number of target power flow rate data points is only one. When there are multiple power flow rate data points, the target power flow rate data can be one or more of the multiple power flow rate data points.

[0044] S130. Determine the mass flow rate of the medium to be determined based on the current medium temperature and the power flow rate target data.

[0045] In this embodiment of the invention, after determining the target power flow data in the power flow data based on the current medium temperature, the mass flow rate of the medium to be determined can be further determined based on the current medium temperature and the target power flow data.

[0046] The above technical solution can compensate for the error in mass flow measurement results caused by changes in medium temperature by using power flow target data, thereby enabling the mass flow meter to accurately determine the mass flow of the medium when the medium temperature changes.

[0047] The technical solution of this embodiment determines the current medium temperature and the power flow data corresponding to the medium whose mass flow rate is to be determined. Based on the current medium temperature, the target power flow data in the power flow data is determined. Thus, based on the current medium temperature and the target power flow data, the mass flow rate of the medium to be determined is determined. This solves the problem that existing methods cannot accurately determine the mass flow rate of the medium, resulting in poor measurement accuracy and adaptability of the mass flow meter. It can accurately determine the mass flow rate of the medium, thereby improving the measurement accuracy and adaptability of the mass flow meter.

[0048] Example 2

[0049] Figure 2 This is a flowchart of a method for determining the mass flow rate of a medium according to Embodiment 2 of the present invention. This embodiment further refines the above-described technical solutions, providing various specific and optional implementation methods for determining the power flow rate data corresponding to the medium whose mass flow rate is to be determined, determining the target power flow rate data in the power flow rate data based on the current medium temperature, and determining the mass flow rate of the medium whose mass flow rate is to be determined based on the current medium temperature and the target power flow rate data. The technical solutions in this embodiment can be combined with various optional solutions in one or more of the above embodiments. For example... Figure 2 As shown, the method may include the following steps:

[0050] S210. Determine the current medium temperature corresponding to the medium whose mass flow rate is to be determined, and the power flow rate data corresponding to the medium whose mass flow rate is to be determined.

[0051] It should be noted that the method for determining the current medium temperature corresponding to the mass flow rate of the medium to be determined in the embodiments of the present invention is not limited, as long as the determination of the current medium temperature corresponding to the mass flow rate of the medium to be determined can be achieved. For example, the current medium temperature corresponding to the mass flow rate of the medium to be determined can be determined by detecting the voltage at different positions on the Wheatstone bridge, or it can be determined by any other method.

[0052] Specifically, Figure 3 This is a schematic diagram of a medium temperature detection circuit for a gas mass flow meter according to Embodiment 2 of the present invention, as shown below. Figure 3As shown, determining the current medium temperature corresponding to the mass flow rate of the medium to be determined by detecting the voltage at different positions on the Wheatstone bridge can specifically include: (1) weakening the voltage signal by the voltage adjustment module 10 on the second bridge arm 62 so that the voltage finally output to the second intermediate node U1 reaches a lower level. (2) detecting the voltage information of the first intermediate node U2 and the voltage information of the second intermediate node U1 by the detection module 30, calculating the current of the temperature measuring resistor based on the voltage information of the first intermediate node U2 and the second intermediate node U2, calculating the impedance information of the temperature measuring resistor RT based on the current of the temperature measuring resistor RT and the voltage information of the first intermediate node U2, and finally calculating the temperature information of the temperature measuring resistor RT based on the relationship between the resistance value of the temperature measuring resistor RT and the temperature information of the temperature measuring resistor RT. (3) calculating the mass flow rate information of the thermal gas by using King's Law, and determining the current medium temperature corresponding to the mass flow rate of the medium to be determined based on the temperature information of the temperature measuring resistor RT.

[0053] For example, using a thermal gas mass flow meter, after the voltage signal is input to the bridge, it enters the second voltage divider network 40 from the second bridge arm 62. The second voltage divider network 40 divides the voltage signal according to the resistance ratio of the first resistor R21 and the second resistor R24 ​​to generate the first voltage divider information. The first voltage divider information is input to the non-inverting input terminal of the first amplification component 11 and amplified and output. After being current-limited by the third resistor R23, the switching component 12 is turned on. The switching component 12 inputs a voltage signal to the inverting input terminal of the first amplification component 11, causing the output voltage to decrease until the voltage signal at the non-inverting input terminal is equal to the voltage signal at the inverting input terminal. At this time, the voltage signal reaches a preset threshold, and the voltage signal can be output to the second intermediate node U1. After being divided by the first voltage divider network 20, the voltage signal enters the first bridge arm 61, and after being divided again, it is output to the temperature measuring resistor RT. The temperature measuring resistor RT starts working and measures the medium temperature. The voltage information of the second intermediate node and the voltage information of the first intermediate node U2 are calculated based on the first voltage information and the second voltage information output from the output terminal. The current of the temperature measuring resistor RT is calculated based on the voltage information of the second intermediate node U1 and the voltage information of the first intermediate node U2. Then, the impedance information of the temperature measuring resistor RT is calculated based on the current of the temperature measuring resistor RT and the voltage information of the first intermediate node U2. Finally, the temperature information of the temperature measuring resistor RT is calculated based on the relationship between the resistance value of the temperature measuring resistor RT and the temperature information of the temperature measuring resistor RT. Thus, the current medium temperature corresponding to the mass flow rate of the medium to be determined is determined based on the temperature information of the temperature measuring resistor RT.

[0054] Optionally, determining the power-flow data corresponding to the mass flow rate medium to be determined may include: determining at least one preset temperature data of the mass flow rate medium to be determined; acquiring the flow meter power and flow rate of the mass flow rate medium to be determined at each preset temperature data; and determining the power-flow data based on each preset temperature data and the flow meter power and flow rate corresponding to each preset temperature data.

[0055] The preset temperature data can be any temperature of the medium whose mass flow rate is to be determined, set in advance. The flow meter power can be the power of the mass flow meter calculated when the temperature of the medium to be determined is the preset temperature data. Optionally, the flow meter power can be the flow meter heating power. The flow meter flow rate can be the flow rate of the medium flowing through the mass flow meter when the temperature of the medium to be determined is the preset temperature data.

[0056] Specifically, the preset temperature data of the medium to be measured for mass flow rate is determined, and the flow meter power and flow rate of the medium at the preset temperature data are acquired. Power-flow data is then determined based on the preset temperature data and the corresponding flow meter power and flow rate. It can be understood that when there is only one preset temperature data point, one flow meter power and one flow meter flow rate can be determined, thus determining one power-flow data point. When there are multiple preset temperature data points, multiple flow meter powers and multiple flow meter flows can be determined, thus determining multiple power-flow data points. In other words, a power-flow data point can include one preset temperature data point, one flow meter power point, and one flow meter flow rate point.

[0057] Optionally, after determining the preset temperature data of the medium to be determined, the temperature of the medium to be determined can be adjusted to the preset temperature data, and different flow rates of the medium to be determined can be adjusted to determine the flow meter power and flow rate of the medium to be determined at the preset temperature data, thereby determining the power-flow curve data based on the preset temperature data, flow meter power and flow rate.

[0058] Figure 4 This is a structural block diagram of a high-temperature testing fixture provided in Embodiment 2 of the present invention. Exemplarily, it can be used as follows... Figure 4The high-temperature testing fixture shown acquires the flow meter power and flow rate of the medium to be determined at high medium temperatures (e.g., 40℃ and 60℃). Specifically, the temperature of the medium to be determined can be adjusted to 40℃ or 60℃ using a heating machine, and the different flow rates of the medium to be determined can be adjusted using a frequency-modulated fan. The flow meter power (i.e., the heating power of the meter being tested) of the medium to be determined at 40℃ and 60℃ is then determined using a standard differential pressure flow meter, thereby determining the flow meter flow rate (i.e., the flow rate of the meter being tested) of the medium to be determined at 40℃ and 60℃, thus establishing the power-flow rate curve data at 40℃ and 60℃.

[0059] Figure 5 This is a structural block diagram of a low-temperature testing fixture provided in Embodiment 2 of the present invention. In another example, it can be achieved through, as shown in... Figure 5 The high-temperature testing fixture shown acquires the flow meter power and flow rate of the medium to be determined at low medium temperatures (e.g., -20℃, 0℃, and 20℃). Specifically, the temperature of the medium to be determined can be adjusted to -20℃, 0℃, or 20℃ using a chiller, and the different flow rates of the medium to be determined can be adjusted using a frequency-controlled fan. The flow meter power (i.e., the heating power of the meter being measured) of the medium to be determined at -20℃, 0℃, and 20℃ is then determined by bridge calculation on a Wheatstone bridge. The flow rate (i.e., the flow rate of the meter being measured) of the medium to be determined at -20℃, 0℃, and 20℃ is then determined using a standard differential pressure flow meter, thereby establishing the power-flow rate curve data at -20℃, 0℃, and 20℃.

[0060] Figure 6 This is a schematic diagram of power flow data provided in Embodiment 2 of the present invention, exemplarily, as shown below. Figure 6 As shown, the power-flow data can be power-flow curve data. The horizontal axis can represent the flow rate of the flow meter, the vertical axis can represent the power of the flow meter, T1-T5 can represent different preset temperature data of the medium whose mass flow rate is to be determined, and Tx can represent the current temperature of the medium whose mass flow rate is to be determined.

[0061] The above technical solution allows for easy setup of high-temperature and low-temperature testing fixtures, and enables the determination of power and flow rate data relatively easily through these fixtures. By determining the power and flow rate curve data under different preset temperature conditions, it can flexibly cover the current operating conditions of the medium temperature.

[0062] S220. Based on the current medium temperature, determine the first target temperature data and the second target temperature data in the power flow data.

[0063] The first target temperature data can be a target value for each temperature data point in the power-flow data. The second target temperature data can be another target value for each temperature data point in the power-flow data. It is understood that when the power-flow data includes only the flow meter power and flow rate corresponding to one temperature data point, the first and second target temperature data can be the same.

[0064] In this embodiment of the invention, after determining the current medium temperature and power flow data corresponding to the medium to be determined, the first target temperature data and the second target temperature data in the power flow data can be further determined based on the current medium temperature.

[0065] Optionally, determining the first target temperature data and the second target temperature data in the power flow data based on the current medium temperature may include: determining each current temperature data in the power flow data, and determining a first threshold temperature data in each current temperature data based on each current temperature data; if it is determined that the current medium temperature is greater than the first threshold temperature data, determining the first threshold temperature data as the first target temperature data; determining adjacent temperature data of the first threshold based on the first threshold temperature data, and determining the adjacent temperature data of the first threshold as the second target temperature data.

[0066] The current temperature data can be the temperature data included in the current power flow data. The first threshold temperature data can be a threshold data in the current temperature data, such as the maximum value in the current temperature data, and this embodiment of the invention does not limit this. The temperature data adjacent to the first threshold can be a current temperature data that is adjacent to the first threshold temperature data.

[0067] Specifically, after determining the current medium temperature and power flow data corresponding to the medium to be determined, the current temperature data in the power flow data can be further determined. Based on these current temperature data, a first threshold temperature data can be determined, thereby determining the magnitude of the current medium temperature relative to the first threshold temperature data. When the current medium temperature is greater than the first threshold temperature data, the first threshold temperature data can be determined as the first target temperature data. Furthermore, adjacent temperature data can be determined based on the first threshold temperature data, thus defining the adjacent temperature data as the second target temperature data.

[0068] For example, Figure 7 This is a schematic diagram of a current medium temperature exceeding a first threshold temperature, provided in Embodiment 2 of the present invention. Figure 7As shown, assuming the current medium temperature (i.e., Tx) is 70℃, and the current temperature data includes -20℃, 0℃, 20℃, 40℃ and 60℃, then the first threshold temperature data, which is also the first target temperature data, can be 60℃ (i.e., T1), and the adjacent temperature data of the first threshold, which is also the second target temperature data, can be 40℃ (i.e., T2).

[0069] Optionally, determining the first target temperature data and the second target temperature data in the power flow data based on the current medium temperature may further include: determining the second threshold temperature data in each current temperature data based on each current temperature data; determining the second threshold temperature data as the second target temperature data when the current medium temperature is determined to be less than the second threshold temperature data; determining the second threshold adjacent temperature data based on the second threshold temperature data, and determining the second threshold adjacent temperature data as the first target temperature data.

[0070] The second threshold temperature data can be another threshold data in the current temperature data, such as the minimum value in the current temperature data, and this embodiment of the invention does not impose any limitations on it. The adjacent temperature data of the second threshold can be a current temperature data that is adjacent to the second threshold temperature data.

[0071] Specifically, after determining the current temperature data in the power flow data, a second threshold temperature data can be further determined based on the current temperature data, thereby determining the magnitude of the current medium temperature relative to the second threshold temperature data. When the current medium temperature is lower than the second threshold temperature data, the second threshold temperature data can be determined as the second target temperature data, and adjacent temperature data of the second threshold can be determined based on the second threshold temperature data, thereby determining the adjacent temperature data of the second threshold as the first target temperature data.

[0072] For example, Figure 8 This is a schematic diagram of data showing that the current medium temperature is less than the second threshold temperature, as provided in Embodiment 2 of the present invention. Figure 8 As shown, assuming the current medium temperature (i.e., Tx) is -25℃, and the current temperature data includes -20℃, 0℃, 20℃, 40℃ and 60℃, then the second threshold temperature data, which is also the second target temperature data, can be -20℃ (i.e., T5), and the adjacent temperature data of the second threshold, which is also the first target temperature data, can be 0℃ (i.e., T4).

[0073] Optionally, determining the first target temperature data and the second target temperature data in the power flow data based on the current medium temperature may further include: when the current medium temperature is less than the first threshold temperature data and greater than the second threshold temperature data, determining the first medium temperature adjacent data and the second medium temperature adjacent data in each current temperature data based on the current medium temperature; determining the first medium temperature adjacent data as the first target temperature data, and determining the second medium temperature adjacent data as the second target temperature data.

[0074] The first adjacent temperature data can be any current temperature data that is adjacent to and greater than the current medium temperature. The second adjacent temperature data can be any current temperature data that is adjacent to and less than the current medium temperature.

[0075] Specifically, after determining the first threshold temperature data and the second threshold temperature data based on the current temperature data, the relative values ​​of the current medium temperature and the first and second threshold temperature data can be further determined. When the current medium temperature is less than the first threshold temperature data but greater than the second threshold temperature data, adjacent data of the first and second medium temperatures can be determined based on the current medium temperature data. The adjacent data of the first medium temperature is then determined as the first target temperature data, and the adjacent data of the second medium temperature is determined as the second target temperature data.

[0076] For example, Figure 9 This is a schematic diagram of a current medium temperature that is less than a first threshold temperature and greater than a second threshold temperature, as provided in Embodiment 2 of the present invention. Figure 9 As shown, assuming the current medium temperature (i.e., Tx) is 55℃, and the current temperature data includes -20℃, 0℃, 20℃, 40℃ and 60℃, then the first medium temperature adjacent data, i.e. the first target temperature data, can be 60℃ (i.e., T1), and the second medium temperature adjacent data, i.e. the second target temperature data, can be 40℃ (i.e., T2).

[0077] S230. Based on the first target temperature data, determine the first power flow target data in the power flow data.

[0078] The first power flow rate target data can be a target data point in the power flow rate data that corresponds to the first target temperature data.

[0079] In this embodiment of the invention, after determining the first target temperature data in the power flow data based on the current medium temperature, the first power flow target data in the power flow data can be further determined based on the first target temperature data.

[0080] S240. Based on the second target temperature data, determine the second power flow target data in the power flow data.

[0081] The second power flow rate target data can be a target data point in the power flow rate data that corresponds to the second target temperature data.

[0082] In this embodiment of the invention, after determining the second target temperature data in the power flow data based on the current medium temperature, the second power flow target data in the power flow data can be further determined based on the second target temperature data.

[0083] It should be noted that, Figure 2 This is just a schematic diagram of one implementation method. Steps S230 and S240 are not related in any order. You can implement step S230 first and then step S240, or you can implement step S240 first and then step S230, or you can implement them in parallel.

[0084] S250. Determine the mass flow rate of the medium to be determined based on the current medium temperature, the first power flow rate target data, and the second power flow rate target data.

[0085] In this embodiment of the invention, after determining the first power flow target data in the power flow data based on the first target temperature data, and determining the second power flow target data in the power flow data based on the second target temperature data, the mass flow rate of the medium to be determined can be further determined based on the current medium temperature, the first power flow target data, and the second power flow target data.

[0086] Optionally, determining the mass flow rate of the medium to be determined based on the current medium temperature, the first power flow rate target data, and the second power flow rate target data may include: determining the current power data corresponding to the medium to be determined; determining the first target flow rate data corresponding to the current power data in the first power flow rate target data based on the current power data; determining the second target flow rate data corresponding to the current power data in the second power flow rate target data based on the current power data; and determining the mass flow rate of the medium to be determined based on the current medium temperature, the first target flow rate data, the first target temperature data, the second target flow rate data, and the second target temperature data.

[0087] The current power data can be the power data of the medium when determining the mass flow rate. It should be noted that the embodiments of the present invention do not limit the specific implementation method for determining the current power data, as long as the determination of the current power data can be achieved. It can be understood that in the power flow rate data, the first target temperature data can correspond to multiple flow meter flow rates, and the first target flow rate data can be the flow rate corresponding to the current power data among the multiple flow meter flow rates corresponding to the first target temperature data. Correspondingly, the second target temperature data can also correspond to multiple flow meter flow rates, and the second target flow rate data can be the flow rate corresponding to the current power data among the multiple flow meter flow rates corresponding to the second target temperature data.

[0088] Specifically, after determining the first power flow target data in the power flow data based on the first target temperature data, and determining the second power flow target data in the power flow data based on the second target temperature data, the current power data corresponding to the mass flow medium to be determined can be further determined, so as to determine the first target flow data and the second target flow data based on the current power data, thereby determining the mass flow of the mass flow medium to be determined based on the current medium temperature, the first target flow data, the first target temperature data, the second target flow data, and the second target temperature data.

[0089] For example, such as Figure 6 As shown, Px represents the current power data, and the mass flow rate of the medium to be determined can be based on the following formula:

[0090]

[0091] Where, q x This represents the mass flow rate of the medium to be determined, q1 represents the first target flow rate data, q2 represents the second target flow rate data, T1 represents the first target temperature data, T2 represents the second target temperature data, and T... x This indicates the current temperature of the medium.

[0092] For example, in an application scenario where the current medium temperature is greater than the first threshold temperature data, i.e., T x At temperatures above 60℃, such as Figure 7 As shown, the mass flow rate of the medium to be determined can be based on the following formula:

[0093]

[0094] For example, in an application scenario where the current medium temperature is less than the second threshold temperature data, i.e., T x At temperatures below -20℃, such as Figure 8 As shown, the mass flow rate of the medium to be determined can be based on the following formula:

[0095]

[0096] Among them, T4 is the first target temperature data, which is 0℃; T5 is the second target temperature data, which is -20℃.

[0097] For example, in an application scenario where the current medium temperature is lower than the first threshold temperature data but higher than the second threshold temperature data, i.e., -20℃ <T x At temperatures below 60℃, such as Figure 9 As shown, 40℃ <T x When the temperature is below 60℃, the mass flow rate of the medium to be determined can be based on the following formula:

[0098]

[0099] The technical solution of this embodiment determines the current medium temperature and power flow data corresponding to the medium whose mass flow rate is to be determined. Based on the current medium temperature, it determines the first target temperature data and the second target temperature data in the power flow data. Based on the first target temperature data, it determines the first power flow target data in the power flow data, and based on the second target temperature data, it determines the second power flow target data in the power flow data. Thus, based on the current medium temperature, the first power flow target data, and the second power flow target data, the mass flow rate of the medium to be determined is determined. This solves the problem that existing methods cannot accurately determine the mass flow rate of the medium, resulting in poor measurement accuracy and adaptability of the mass flow meter. It can accurately determine the mass flow rate of the medium, thereby improving the measurement accuracy and adaptability of the mass flow meter.
