Description

Background Art

[0002] When using a device to produce a target object that needs to be brewed with water, especially a device that needs to produce the target object through high-pressure brewing, the specific process of such a device for producing the target object includes a pressure accumulation stage and a constant pressure stage. Among them, the pressure accumulation stage is to increase the pressure in the brewing chamber of the device to the target pressure value, so as to enter the constant pressure stage and the device discharges the target object. In this process, the water intake of the device includes the makeup water for the pressure accumulation stage and the water output for the constant pressure stage. The makeup water is used to increase the pressure to the target pressure value, and the water output corresponds to the target cup volume.

[0003] In the related art, when using a device to produce a target object with a target cup volume, the makeup water for the pressure accumulation stage is determined according to the raw material amount of the target object. In other words, a fixed makeup water for the pressure accumulation stage corresponds to the raw material amount of a target object. For example, when making 40 g of coffee, the output amount in the constant pressure stage is 40 g. Among them, the makeup water for the pressure accumulation stage corresponding to the amount of coffee powder for making 40 g of coffee is 32 g, and the actual total water intake is 72 g.

[0004] However, the pipeline pressure in the device is not constant, so the makeup water for the pressure accumulation stage corresponding to the raw material amount of the same target object is also not constant. At this time, if the same raw material amount of the target object is still processed according to a fixed makeup water amount, the influence of the pipeline pressure is ignored, which affects the accuracy of determining the actual cup volume.

[0073] Overview

[0074] The following briefly introduces the design concept of the embodiments of this application:

[0075] When using a device to produce a target object that needs to be brewed with water, especially a device that needs to produce the target object through high-pressure brewing, the specific process of producing the target object by such a device includes a pressure accumulation stage and a constant pressure stage. Among them, the pressure accumulation stage is to increase the pressure in the brewing chamber of the device to the target pressure value, so as to enter the constant pressure stage and the device discharges the target object. In this process, the water intake of the device includes the water replenishment amount for the pressure accumulation stage and the water output amount for the constant pressure stage. The water replenishment amount is used to increase the pressure to the target pressure value, and the water output amount corresponds to the target cup amount.

[0076] In the related art, when using a device to produce a target object with a target cup amount, the water replenishment amount in the pressure accumulation stage is determined according to the raw material amount of the target object. In other words, a fixed water replenishment amount in the pressure accumulation stage corresponds to the raw material amount of a target object. For example, when making 40g of coffee, the output amount in the constant pressure stage is 40g. Among them, the water replenishment amount in the pressure accumulation stage corresponding to the coffee powder amount for making 40g of coffee is 32g, so the actual total water intake is 72g.

[0077] However, the pipeline pressure in the device is not constant, so the water replenishment amount in the pressure accumulation stage corresponding to the raw material amount of the same target object is also not constant. At this time, if the same raw material amount of the target object is still processed according to a fixed water replenishment amount, the influence of the pipeline pressure is ignored, which affects the accuracy of determining the actual cup amount.

[0078] In view of this, the embodiments of the present application provide a cup amount determination method, a beverage machine, an electronic device and a storage medium, which determine whether the generation process of the target object enters the constant pressure stage. When it is determined that the constant pressure stage is entered, a cup amount parameter is obtained. The cup amount parameter represents the cup amount corresponding to a pulse signal of the flow meter in the constant pressure stage. Then, based on the cup amount parameter, the cup amount of the generated target object is determined. Since the cup amount parameter is the cup amount corresponding to a pulse signal of the flow meter in the constant pressure stage, when calculating the cup amount of the generated target object, it can be realized based on the pulse signal in the constant pressure stage, and thus it is not affected by air pressure fluctuations, making the calculation of the cup amount of the target object more accurate.

[0079] The following describes the preferred embodiments of the present application with reference to the accompanying drawings of the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. And without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0080] Exemplary Application Scenarios

[0081] The preferred embodiments of the present application will be described below in conjunction with the accompanying drawings of the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. And without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0082] As Figure 1 shown, it is a schematic diagram of an application scenario provided by an embodiment of the present application. The application scenario schematic diagram includes a device 101 for making a target object and a processor 102 disposed inside the device 101. Among them, when the target object is coffee, the device 101 is a coffee machine; when the target object is tea, the device 101 can be a tea extractor. The processor 102 determines whether the generation process of the target object enters a constant pressure stage, and when it is determined that the constant pressure stage is entered, obtains the cup volume parameter of the target object from the device 101, and determines the cup volume of the target object based on the cup volume parameter.

[0083] As Figure 2 shown, it is a schematic diagram of an application scenario provided by an embodiment of the present application. In this application scenario schematic diagram, it includes a server 201 and a terminal device 202. Among them, the server 201 and the terminal device 202 are connected through a communication network. Of course, the communication network can be a wired network or a wireless network.

[0084] The server 201 can be an independent physical server 201, or an edge device in the field of cloud computing, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud storage, cloud functions, network services, cloud communications, middleware services, domain name services, security services, Content Delivery Network (English name: Content Delivery Network, abbreviated as CDN), and big data and artificial intelligence platforms. The terminal device 202 is a device for making a target object, such as a coffee machine, a tea extractor, etc. Among them, the terminal device 202 can be installed with a client related to cup volume determination. The client can be software (for example, APP, browser, short video software, etc.), or a web page, a small program, etc. The user of the terminal device 202 can use the client through the terminal device 202 for human-computer interaction.

[0085] It should be noted that the power supply method in the embodiments of the present application can be executed independently by the server 201 or the terminal device 202, or jointly executed by the terminal device 202 and the server 201. For example, when jointly executed by the server 201 and the terminal device 202, the server 201 determines whether the generation process of the target object enters the constant pressure stage, and when it is determined that the constant pressure stage is entered, the server 201 instructs the terminal device 202 to obtain the cup volume parameter corresponding to the target object, where the cup volume parameter represents the cup volume corresponding to one pulse signal of the flowmeter; when the terminal device 202 obtains the cup volume parameter corresponding to the target object, the terminal device 202 transmits the cup volume parameter to the server 201; the server 201 then determines the cup volume of the generated target object based on the cup volume parameter.

[0086] Exemplary Method

[0087] Next, in combination with the above system architecture, the spool control method provided by the exemplary embodiment of the present application will be described with reference to the accompanying drawings. It should be noted that the above system architecture is only shown for the convenience of understanding the spirit and principle of the present application, and the embodiments of the present application are not limited in this regard.

[0088] As Figure 3 shown, it is a flowchart of the implementation of a cup volume determination method provided by an embodiment of the present application. Here, the processor shown in Figure 1 is used as the execution subject for introduction. The specific implementation process of this method is as follows:

[0089] S301, determine whether the generation process of the target object enters the constant pressure stage;

[0090] S302, if so, obtain the cup volume parameter, where the cup volume parameter represents the cup volume corresponding to one pulse signal of the flowmeter in the constant pressure stage;

[0091] S303, determine the cup volume of the generated target object based on the cup volume parameter.

[0092] In the embodiments of the present application, by determining whether the generation process of the target object enters the constant pressure stage, when it is determined that the constant pressure stage is entered, the cup volume parameter is obtained, where the cup volume parameter represents the cup volume corresponding to one pulse signal of the flowmeter in the constant pressure stage, and then the cup volume of the generated target object is determined based on the cup volume parameter. Since the cup volume parameter is the cup volume corresponding to one pulse signal of the flowmeter in the constant pressure stage, when calculating the cup volume of the generated target object, it can be achieved based on the pulse signal in the constant pressure stage, and thus it is not affected by air pressure fluctuations, making the calculation of the cup volume of the target object more accurate.

[0093] Based on this, one of the core points of the embodiments of the present application when obtaining the cup volume parameter. Among them, the specific way to obtain the cup volume parameter can be: calculating the ratio of the actual cup volume of the target object to the target cup volume generated in the constant pressure stage; multiplying the ratio by a preset parameter to obtain the cup volume parameter; where the preset parameter represents the cup volume corresponding to one pulse signal of the flow meter.

[0094] For example, when making coffee with a coffee machine, a k value (preset parameter) is set for the coffee machine, and the specific value of the k value is 0.1. Then, when making coffee with a target cup volume of 150 g through the coffee machine, but the actual cup volume of the obtained coffee is 120 g, the cup volume parameter is further obtained as 120 / 150 * 0.1 = 0.08, and this value is input into the coffee machine.

[0095] Through the above method, the cup volume parameter is obtained by using the ratio between the actual cup volume and the target cup volume generated in the constant pressure stage. Thus, through the cup volume parameter, the determination process of the cup volume generated by the target object can be transformed into the constant pressure stage, and thus it is not affected by air pressure fluctuations.

[0096] It should be noted that in a possible embodiment, the cup volume parameter corresponding to the target object can be obtained first, and then it is judged whether the generation process of the target object enters the constant pressure stage. When entering the constant pressure stage, based on the cup volume parameter, the cup volume generated by the target object is determined.

[0097] Considering that when using a device to make a target object, such as coffee, the external water source generally first passes through a flow meter, then enters a water pump, a boiler, and finally flows out through a brewer. In this process, the pressure in the brewing chamber inside the brewer generally needs to reach the target pressure value to flow out coffee. Among them, the target pressure value is determined according to the type and model of the device. For example, the target pressure value corresponding to a coffee machine is generally 7 bar, but there are also differences between the target pressure values of different coffee machines. Before flowing out the target object, it is necessary to pump water through the water pump for pressure accumulation until the pressure in the brewing chamber inside the brewer rises to 7 bar before coffee can flow out normally. And during the pressure accumulation stage, the pipeline pressure inside the entire device is in a fluctuating state. As Figure 4A shown is the pressure curve change during the generation process of the target object, Figure 4B is the period diagram of the flow meter pulse signal, where Figure 4A the relatively dense stage is the constant pressure stage, and after stretching it, the overall trend is basically similar to Figure 4B the basic one.

[0098] Based on this, when determining whether the manufacturing process of the target object enters the constant pressure stage, it can be achieved based on the flowmeter pulse signal, thus eliminating the need to add a pressure sensor and saving costs. First, obtain the flowmeter pulse signal corresponding to the generation process of the target object; then, based on the flowmeter pulse signal, determine whether the generation process of the target object enters the constant pressure stage. Specifically: determine the current pulse signal period corresponding to the flowmeter pulse signal; then, when the current pulse signal period meets the preset conditions, determine that the generation process of the target object enters the constant pressure stage, including:

[0099] When the current pulse signal period is greater than the previous pulse signal period, use the current pulse signal period as the maximum pulse period; where the previous pulse signal period is the maximum pulse period determined based on the previously obtained flowmeter pulse signal; or when the current pulse signal period is less than the previous pulse signal period, use the previous pulse signal period as the maximum pulse period; based on the maximum pulse period, determine that the generation process of the target object enters the constant pressure stage.

[0100] Among them, when the current pulse signal period is less than the previous pulse signal period, still use the previous pulse signal period as the maximum pulse period. This is because the pulse signal period has reached the maximum value, and the maximum value represents the period when approaching the maximum pressure. Other lower values that appear later are likely to be the pulse signal periods during the constant pressure stage. Therefore, only considering the maximum pulse period for judgment is more accurate.

[0101] It should be understood that during the pressure accumulation stage, the pulse signal period of the flowmeter shows an increasing trend. If it is determined from the change curve of the pulse signal period corresponding to the flowmeter pulse signal that the pulse signal period reaches the maximum value, it is considered that the manufacturing process of the target object is in the constant pressure stage; on the contrary, if it is determined from the change curve of the pulse signal period corresponding to the flowmeter pulse signal that the pulse signal period does not reach the maximum value and is still in an increasing trend, it is initially considered that the generation process of the target object is in the pressure accumulation stage. At this time, based on the maximum pulse period, it is necessary to further determine whether the generation process of the target object enters the constant pressure stage. The specific determination methods include:

[0102] When the maximum pulse period is greater than the preset period, adjust at least one parameter;

[0103] Among the adjusted at least one parameter, when there is a parameter greater than or equal to the preset threshold set for the parameter, determine that the generation process of the target object enters the constant pressure stage.

[0104] In this way, when the obtained maximum pulse period reaches the preset period, it is not directly determined to enter the constant pressure stage, but subsequent pulse signals are continuously obtained through at least one parameter, improving the accuracy of the constant pressure stage judgment.

[0105] Exemplarily, referring to Figure 5 , a constant pressure stage determination method provided by an embodiment of the present application, and the specific implementation method process includes the following steps:

[0106] S501, determine whether the maximum pulse period corresponding to the current pulse signal is greater than a first preset value;

[0107] Among them, before determining the maximum pulse period of the current pulse signal, it is necessary to first filter the acquired pulse signal to remove abnormal data.

[0108] Furthermore, determine whether the maximum pulse period is greater than the first preset value. Among them, the first preset value is determined according to the type of device and the signal type. In this application, the unit of the pulse signal period is millisecond (ms). The unit is omitted when describing the pulse period signal later. It can take a value of 120, or it can also take values such as 119 and 118. No specific limitation is made here. The specific value mainly depends on the pipeline difference in the device. If the pipeline pressure in the device is large, a larger value is taken; otherwise, a smaller value is taken. The first preset value represents the preset maximum pulse period. When the maximum value of the pulse signal period of the flowmeter appears, it can be considered that the subsequent stage is a constant pressure stage. Then, when the maximum pulse period corresponding to the current pulse signal is greater than the first preset value, it can be considered that the generation process of the current target object is close to the constant pressure stage. Whether to enter the constant pressure stage specifically still requires obtaining subsequent pulse signals for judgment.

[0109] S501, when the maximum pulse period is greater than the first preset value, adjust the first parameter, the second parameter, and the third parameter;

[0110] Among them, the first parameter, the second parameter, and the third parameter represent the number of currently acquired pulse signals. When adjusting the first parameter, the second parameter, and the third parameter, it can be to add a set value to the first parameter, the second parameter, and the third parameter respectively. For example: add 1. In the embodiment of the present application, the adjustment method of the first parameter, the second parameter, and the third parameter is not specifically limited.

[0111] S503, when the adjusted first parameter is greater than or equal to the first threshold, or the adjusted second parameter is greater than or equal to the second threshold, or the adjusted third parameter is greater than or equal to the third threshold, determine that the generation process of the target object enters the constant pressure stage.

[0112] Among them, the first threshold, the second threshold, and the third threshold represent the preset number of pulse signals. The value of the first threshold can be 6. Of course, it can also take values such as 5 and 7; the value of the second threshold can be 12. Of course, it can also take values such as 11 and 13; the value of the third threshold can be 18. Of course, it can also take values such as 17 and 19. No specific limitation is made here for the values of the first threshold, the second threshold, and the third threshold.

[0113] When it is determined that the adjusted first parameter is greater than or equal to the first threshold, or the adjusted second parameter is greater than or equal to the second threshold, or the adjusted third parameter is greater than or equal to the third threshold, it is determined that the generation process of the target object enters the constant pressure stage. In this way, after it is determined that the generation process of the target object is approaching the constant pressure stage, subsequent pulse signals are continuously obtained through the first parameter, the second parameter, or the third parameter, improving the accuracy of the determination in the constant pressure stage.

[0114] In a possible embodiment, referring to Figure 6 , Figure 6 the method shown also includes:

[0115] S601, when the maximum pulse period is less than or equal to the first preset value, determine whether the maximum pulse period is greater than the second preset value;

[0116] Wherein, the second preset value is less than the first preset value, and the second preset value is also determined according to the type of the device and the signal type. It can take the value of 110, or can also take the value of 109, 108, etc. No specific limitation is made here. The specific value mainly depends on the pipeline difference in the device. If the pipeline pressure in the device is large, the value is larger; otherwise, the value is smaller. The second preset value also represents the preset maximum pulse period. When the maximum value of the pulse signal period of the flowmeter appears, it can be considered that the subsequent stage is the constant pressure stage. Then, when the maximum pulse period corresponding to the current pulse signal is greater than the second preset value, it can be considered that the generation process of the current target object is approaching the constant pressure stage. Whether it specifically enters the constant pressure stage still needs to obtain subsequent pulse signals for judgment.

[0117] It should be noted that when determining whether the maximum pulse period is greater than the second preset value, another judgment step can be added: determine whether the maximum pulse period is greater than the iteration parameter Hmax. Then step S601 is essentially: when the maximum pulse period is less than or equal to the first preset value, determine whether the maximum pulse period is greater than the second preset value and greater than the iteration parameter.

[0118] Among them, after each determination of entering the constant pressure stage, the iterative parameter Hmax needs to be updated. The value of the iterative parameter Hmax is determined by the maximum pulse period of the previously generated target object. The specific calculation method is Hmax = (Tmax – X) / 10 * 10, where X takes the value of 20. Of course, it can also take values such as 18 or 19, and specific limitations are not made here. Tmax is the maximum pulse period. When the device generates the target object for the first time, the default value of Hmax can be equal to the minimum value among multiple preset pulse signal periods. For example, when there are only two preset maximum pulse periods, namely the first preset value and the second preset value, the default value of Hmax is equal to the second preset value; if there is another preset value smaller than the second preset value, the default value of Hmax is equal to the other preset value. After each generation of the target object and after turning off the water pump, the iterative parameter Hmax participates in numerical iteration. Of course, the default value of Hmax can also be smaller than the minimum value among multiple preset pulse signal periods, and specific limitations are not made here.

[0119] By continuously updating the value of the iterative parameter Hmax, not only can the judgment steps be reduced, but also the value of Hmax can continuously approach the pulse signal period under the actual maximum pressure, that is, it is closer to the pulse signal period in the constant pressure stage. At this time, the calculated cup volume is more accurate.

[0120] S602. When the maximum pulse period is greater than the second preset value, adjust the second parameter and the third parameter;

[0121] When it is determined that the maximum pulse period is greater than the second preset value (if the iterative parameter is considered, it is also necessary to determine that the maximum pulse period is greater than the iterative parameter), adjust the second parameter and the third parameter. The specific adjustment method can be to add a set value to the second parameter and the third parameter respectively. For example, add 1. In the embodiments of the present application, the adjustment method for the second parameter and the third parameter is not specifically limited.

[0122] S603. When the first parameter is greater than or equal to the first threshold, or the adjusted second parameter is greater than or equal to the second threshold, or the adjusted third parameter is greater than or equal to the third threshold, determine that the generation process of the target object enters the constant pressure stage.

[0123] When it is determined that the first parameter is greater than or equal to the first threshold, or the adjusted second parameter is greater than or equal to the second threshold, or the adjusted third parameter is greater than or equal to the third threshold, determine that the generation process of the target object enters the constant pressure stage. In this way, after it is determined that the generation process of the target object is approaching the constant pressure stage, subsequent pulse signals are continuously obtained through the first parameter, the second parameter, or the third parameter, improving the accuracy of the judgment in the constant pressure stage.

[0124] In a possible embodiment, refer toFigure 7 , Figure 7 The method shown also includes:

[0125] S701, when the maximum pulse period is less than or equal to a second preset value, determine whether the maximum pulse period is greater than a third preset value;

[0126] Among them, the third preset value is less than the second preset value, and the third preset value is also determined according to the type of device and the signal type. It can take a value of 100, or it can take a value of 99, 98, etc. There is no specific limitation here. The specific value mainly depends on the pipeline difference in the device. If the pipeline pressure in the device is large, the value is larger; otherwise, the value is smaller. The third preset value also represents the preset maximum pulse period. When the maximum value of the pulse signal period of the flowmeter appears, it can be considered that the subsequent is a constant pressure stage. Then, when the maximum pulse period corresponding to the current pulse signal is greater than the third preset value, it can be considered that the generation process of the current target object is close to the constant pressure stage. Whether to enter the constant pressure stage specifically still requires obtaining subsequent pulse signals for judgment.

[0127] It should be noted that when determining whether the maximum pulse period is greater than the third preset value, another judgment step can be added: determine whether the maximum pulse period is greater than the iteration parameter. Then, step S701 is essentially: when the maximum pulse period is less than or equal to the second preset value, determine whether the maximum pulse period is greater than the third preset value and greater than the iteration parameter.

[0128] S702, when the maximum pulse period is greater than the third preset value, adjust the third parameter;

[0129] When it is determined that the maximum pulse period is greater than the third preset value (if the iteration parameter is considered, it is also necessary to determine that the maximum pulse period is greater than the iteration parameter), adjust the third parameter. The specific adjustment method can be to add a set value to the third parameter, such as adding 1. In the embodiments of the present application, the adjustment method for the third parameter is not specifically limited.

[0130] S703, when the first parameter is greater than or equal to the first threshold, or the second parameter is greater than or equal to the second threshold, or the adjusted third parameter is greater than or equal to the third threshold, determine that the generation process of the target object enters the constant pressure stage.

[0131] When it is determined that the first parameter is greater than or equal to the first threshold, or the second parameter is greater than or equal to the second threshold, or the adjusted third parameter is greater than or equal to the third threshold, determine that the generation process of the target object enters the constant pressure stage. In this way, after it is determined that the generation process of the target object is close to the constant pressure stage, subsequent pulse signals are continuously obtained through the first parameter, the second parameter, or the third parameter, improving the accuracy of the constant pressure stage judgment.

[0132] After determining that the generation process of the target object has entered the constant pressure stage through the above method, further, step S303 is executed, that is, based on the cup volume parameter, the cup volume of the target object is determined. The specific determination method can be: counting the number of pulse signals of the flowmeter in the constant pressure stage; multiplying the cup volume parameter by the number of pulse signals to obtain the cup volume of the target object.

[0133] To elaborate on the above technical solution in more detail, the following will be illustrated through a specific coffee-making scenario. As Figure 8 shown, it is a schematic diagram of a method for determining the coffee cup volume.

[0134] In Figure 8 , the first preset value H1 is set to 120, the second preset value H2 is set to 110, the third preset value H3 is set to 100, the first threshold C1 is set to 6, the second threshold C2 is set to 12, the third threshold C3 is set to 18, and the default value of the iteration parameter Hmax is 100. The above values are all preset values of the coffee machine. Due to machine differences, the preset values of each coffee machine are not the same.

[0135] When determining the coffee cup volume, first collect the flowmeter pulse signal. According to the change trend of the pulse signal period, determine whether it is the pressure accumulation stage. When it is determined to be the pressure accumulation stage, after filtering the collected flowmeter pulse signal, obtain the value t of the current maximum pulse period Tmax, and first compare t with H1. Suppose the first Tmax is 50, then Tmax is less than H1, Tmax is less than H2, and Tmax is less than H3. At this time, the loop count is incremented by 1, and then the above steps are repeated until the determined maximum pulse period reaches 100.

[0136] When the maximum pulse period is above 100, taking 105 as an example, Tmax is less than H1, Tmax is less than H2, but Tmax is greater than H3, then the third parameter P3 is incremented by 1. At this time, the value of P3 is 1, and P3 is less than C3. At this time, the loop count is incremented by 1, and then the above steps are repeated. During the repeated process, the maximum pulse period that may be obtained is 100, but since the previously obtained maximum pulse period is 105, the judgment logic continues with 105 as the maximum pulse period.

[0137] Continue to collect the flowmeter pulse signal. When the maximum pulse period is above 110, taking 115 as an example, Tmax is less than H1, but Tmax is greater than H2, and Tmax is greater than H3, then the second parameter P2 is incremented by 1. At this time, the value of P2 is 1; on the basis of the value of P3 being 1, an additional number of acquisitions between 105 and 115 is added. For example, if the flowmeter pulse signal is acquired 2 times between 105 and 115, then P3 is incremented by 2. At this time, the value of P3 is 3.

[0138] Continue to collect the pulse signals of the flowmeter. When the maximum pulse period is above 120, taking 155 as an example, if Tmax is greater than H1, Tmax is greater than H2, and Tmax is greater than H3, then the first parameter P1 is incremented by 1. At this time, the value of P1 is 1. Based on the value of P2 being 1 and the value of P3 being 3, an additional number of acquisitions between 115 and 125 is added. For example, if 12 acquisitions are made between 115 and 125, then P2 and P3 are incremented by 12. At this time, the value of P2 is 13 and the value of P3 is 15. At this time, if P2 > 12, it is determined that the generation process of the target object enters the constant pressure stage, and the number of pulse signals in the constant pressure stage is calculated. Entering the constant pressure stage, the above judgment logic will not be repeated next time, and the number of pulse signals will be directly increased continuously until the required amount of coffee cups is obtained, then the water pump is turned off, and the iterative parameter Hmax = (Tmax - 20) / 10*10 is updated.

[0139] In the above process, H3 = 100. This value is generally designed to be relatively slightly lower to prevent some coffee machines from having a relatively small pressure due to process errors, and the maximum pulse period value when they reach the constant pressure stage is less than 100, resulting in the inability to find the constant pressure stage, that is, preventing the setting from being too high and unable to find the constant pressure stage, and then resulting in the inability to calculate the amount of coffee cups normally. Similarly, H1 = 120. This value is generally designed to be relatively slightly higher to prevent some coffee machines from having a relatively large pressure due to process errors. When the maximum pulse period value reaches the preset value, even after the above parameter adjustment, they still cannot reach the constant pressure stage, that is, prematurely determining to enter the constant pressure stage, and at this time it is still the pressure accumulation stage, resulting in the inability to obtain accurate cup quantity parameters, and then resulting in the inability to accurately calculate the amount of coffee cups.

[0140] Therefore, by setting H3 = 100, H2 = 110, and H1 = 120, a total of three gears are set to cover various pressure conditions of the coffee machine as much as possible, which helps to detect the maximum signal period during the constant pressure stage and more accurately determine the entry into the constant pressure stage. Additionally, by comparing the maximum pulse period Tmax with H1 first, then with H2, and finally with H3, the computational workload can be reduced. When Tmax is greater than H1, it must be greater than H2 and H3. Moreover, when the obtained maximum pulse period Tmax reaches H1 or H2 or H3, it does not directly determine the entry into the constant pressure stage. Instead, it continues to obtain the subsequent flowmeter pulse signals according to the parameters C1, C2, or C3. When the maximum pulse signal period Tmax is obtained, it is possible that the pressure will increase slightly before entering the constant pressure stage, or it may enter the constant pressure stage after decreasing and stabilizing. Therefore, it is necessary to obtain the subsequent pulse signals to better ensure that the coffee-making process enters the constant pressure stage. Finally, setting the Hmax value is to reduce logical judgments. For example, after making coffee for the first time, update the Hmax value to 110. Then, when it is detected as 115, only the first two judgment logics need to be judged, and the third judgment logic can be omitted. At this time, the pressure is closer to the actual maximum pressure of the coffee machine, and thus closer to the constant pressure stage, and the calculated coffee cup volume is more accurate.

[0141] The following uses a specific example of coffee making to illustrate.

[0142] First, obtain the cup volume parameter. Here, the cup volume parameter takes a value of 0.350 g / pulse. The meaning of the unit of the cup volume parameter is: the amount of water flowing through corresponding to each generated flowmeter pulse signal. Based on this cup volume parameter, to make a target coffee cup volume of 40 g, the number of flowmeter pulse signals to be collected during the constant pressure stage is pulse = 40 g / 0.350 g / single pulse = 114.28, and 115 is taken.

[0143] Next, start collecting the flowmeter pulse signals. It is determined that the current is in the pressure accumulation stage according to the pulse signal period. After filtering the flowmeter pulse signals, Tmax = 50 is obtained. Then, Tmax is less than H1, Tmax is less than H2, and Tmax is less than H3. The loop count is incremented, and it enters the second loop. In the second loop, it is still in the pressure accumulation stage, and Tmax = 60. Then, Tmax is less than H1, Tmax is less than H2, and Tmax is less than H3. The loop count is incremented, and it enters the third loop. In the third, fourth, and fifth loops, it is still in the pressure accumulation stage, and Tmax takes values of 70, 80, and 90 respectively. Then, Tmax is less than H1, Tmax is less than H2, and Tmax is less than H3. The loop count is incremented, and it enters the sixth loop.

[0144] In the sixth cycle, it is still the pressure accumulation stage, and Tmax = 105. Then Tmax is less than H1, Tmax is less than H2, Tmax is greater than H3. The value of P3 is incremented by 1. P3 is less than C3, and the cycle count is incremented. Then it enters the seventh cycle.

[0145] In the seventh cycle, it is still the pressure accumulation stage, and Tmax = 105. Then Tmax is less than H1, Tmax is less than H2, Tmax is greater than H3. The value of P3 is incremented to 2. P3 is less than C3, and the cycle count is incremented. Then it enters the eighth cycle. In the eighth cycle, it is still the pressure accumulation stage, and Tmax = 115. Then Tmax is less than H1, Tmax is greater than H2. The value of P2 is incremented to 1. The value of P3 is incremented to 3. P2 is less than C2, P3 is less than C3, and the cycle count is incremented. Then it enters the ninth cycle.

[0146] In the ninth, tenth, eleventh, twelfth, and thirteenth cycles, it is still the pressure accumulation stage, and Tmax is 115, 100, 105, 110, and 105 respectively, all of which do not exceed 115. Then in these five cycles, Tmax = 115 is taken in all cases. Then Tmax is less than H1, Tmax is greater than H2. The value of P2 is incremented to 6. The value of P3 is incremented to 8. Then P2 is less than C2, P3 is less than C3, and the cycle count is incremented. Then it enters the fourteenth cycle.

[0147] In the fourteenth cycle, it is still the pressure accumulation stage, and Tmax = 125. Then Tmax is greater than H1. The value of P1 is incremented to 1. The value of P2 is incremented to 7. The value of P3 is incremented to 9. Then P1 is less than C1, P2 is less than C2, P3 is less than C3, and the cycle count is incremented. Then it enters the fifteenth cycle.

[0148] In the fifteenth, sixteenth, seventeenth, eighteenth, and nineteenth cycles, it is still the pressure accumulation stage, and Tmax is 120, 121, 111, 122, and 120 respectively, all of which do not exceed 125. Then in these five cycles, Tmax = 125 is taken in all cases. Then Tmax is greater than H1. The value of P1 is incremented to 6. The value of P2 is incremented to 12. The value of P3 is incremented to 14. Then P2 is equal to C2. It is determined to enter the constant pressure stage, and the pulse count in the constant pressure stage is started to be recorded. Then it enters the twentieth to thirty-fifth cycles.

[0149] In the twentieth to one hundred and thirty-fifth cycles, it is the constant pressure stage. The pulse count is incremented to 115. The water pump is turned off, and Hmax = (Tmax – 20) / 10*10 = (125 – 20) / 10*10 = 105 is updated.
