DETAILED DESCRIPTION

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0055] like Figure 1-4 As shown, a commercial soda water intelligent mixing device includes a bracket 1, a controller 2 installed on the surface of the bracket 1, a water pump 3 installed on the outside of the bracket 1 and an intelligent mixing device body 4 installed on the top of the bracket 1. A soda water mixing nozzle 5 and a carbon dioxide air inlet 6 are set on the top of the intelligent mixing device body 4. The controller 2 is used to control the working status of the carbon dioxide air inlet 6 and the soda water mixing nozzle 5. It also includes a first water pressure information acquisition module 7, which is installed on the water pipe A8 and is used to collect the pressure value of the water suction port of the water pump 3; a second water pressure information acquisition module 9 is installed on the water pipe B10 and is used to collect the pressure value of the water outlet of the water pump 3; a first water flow acquisition module 11 is installed on the water pipe C122 and is used to collect the water flow at the water outlet of the water pump 3; a second water flow acquisition module 13 is installed on the elbow water pipe 14 and is used to collect the water flow entering the soda water mixing nozzle 5. The intelligent mixing device body 4 also includes an inner liner 15, the soda water mixing nozzle 5 and the carbon dioxide inlet 6 are arranged above the inner liner 15, an outer liner 16 is provided outside the inner liner 15, and a water injection port 17 is provided above the outer liner 16. The space between the outer liner 16 and the inner liner 15 is used to store water injected from the water injection port 17.

[0056] Its working principle is:

[0057] When using the intelligent mixing device body 4 to prepare soda water, first, water is injected from the water inlet 17 to allow the water to enter between the outer liner 16 and the inner liner 15, then the condenser 18 condenses the water to a certain temperature, and then the water pump 3 pumps the condensed water to the water pump 3, and then sends the water out from the water outlet of the water pump 3, and the water flow is converted into water mist through the soda water mixing nozzle 5 and injected into the inner liner 15. At the same time, by injecting carbon dioxide into the carbon dioxide inlet 6, the water and carbon dioxide react in the inner liner 15 to generate water mist, so that the reaction is more convenient and quick to generate soda water. Example

[0058] When there is a problem with the water pump 3, there may be problems with the water entering the inner tank 15, which may cause problems with the quality of the soda water produced, which does not meet the original merchant's expectations. However, the smart mixing device body 4 is still working. In order to reduce losses, it is necessary to evaluate the smart mixing device body 4 in a timely manner and respond.

[0059] The specific steps are as follows

[0060] As shown in the figure, a commercial soda water intelligent mixing device includes the following steps:

[0061] S1, obtain the pressure value of the water outlet of the water pump 3 and the pressure value of the water outlet of the water pump 3 of the controller 2 within the time T through the first water pressure information acquisition module 7 and the second water pressure information acquisition module 9, and calculate the water pressure difference coefficient through the pressure value of the water inlet of the water pump 3 and the pressure value of the water outlet of the water pump 3;

[0062] S2. Obtain the water flow rate at the water outlet of the water pump 3 and the water flow rate entering the soda water mixing nozzle 5 of the controller 2 within time T through the first water flow acquisition module 11 and the second water flow acquisition module 13, and calculate the outlet deviation coefficient based on the water flow rate at the water outlet of the water pump 3 and the water flow rate entering the soda water mixing nozzle 5;

[0063] S3, obtaining the supply voltage stability range preset by the controller 2 within time T, then obtaining the real-time voltage value through the monitoring system, and calculating the supply voltage instability coefficient by combining the supply voltage range obtained within time T and the real-time voltage value;

[0064] S4, transmitting the water pressure differential coefficient, the water outlet deviation coefficient, and the power supply voltage instability coefficient to the central processing unit for comprehensive analysis, and establishing and calculating the evaluation coefficient;

[0065] S5. Compare the evaluation coefficient with a preset evaluation coefficient threshold, and control the working state of the entire mixing device according to the comparison result.

[0066] Equipment performance information includes water pressure differential coefficient and outlet deviation coefficient;

[0067] Water pressure differential coefficient: refers to the stability of the difference between the pressure at the water inlet of the water pump 3 and the pressure at the water outlet of the water pump 3 in the intelligent mixing device body 4; in the entire device for preparing soda water, in order to ensure that the taste of the prepared soda water remains consistent, in this device, the soda water is made by pumping the injected water into the water pump 3 through the water pump 3, and then the water pump 3 pumps the water pumped into the water pump 3 out and sends it into the intelligent mixing device body 4, so in this process, there will be a pressure at the water inlet of the water pump 3 and the water outlet of the water pump 3, and the difference between the two pressures is within an expected range; if the difference between the two pressures is too large, greater than the expected range, it proves that the water pressure differential coefficient between the soda water is too large, and at this time there is a problem with the water pump 3, resulting in the soda water produced not meeting the expected taste or there is a problem with the soda water produced, and the influence coefficient is greater;

[0068] An excessively large water pressure differential coefficient has the following effects:

[0069] Unstable beverage quality: Large variations can result in an uneven mix of ingredients in a beverage. This means the ratio of carbon dioxide gas to water in the beverage may vary, affecting the consistency of taste and quality. Customers may experience issues such as one beverage being colder or cooler, or more or less carbonated than another.

[0070] Waste of resources: If the pumping pressure of the water pump 3 is much greater than the spraying pressure, water and carbon dioxide gas may be wasted, which not only increases operating costs but may also have a negative impact on the environment.

[0071] Equipment Wear: Excessive pressure differentials may cause additional wear on equipment components, such as the water pump 3 and the sprinkler system, which may reduce the life of the equipment and increase the need for maintenance and repair.

[0072] Operational instability: Excessive pressure differentials may cause unstable operation of the equipment, potentially requiring more frequent maintenance and calibration, increasing downtime and maintenance costs.

[0073] Therefore, the stability of the difference between the pressure at the water pump 3 suction port and the pressure at the water pump 3 outlet is very important. The logic for obtaining the water pressure differential coefficient is:

[0074] The logic for obtaining the water pressure differential coefficient is as follows:

[0075] S1, obtain the pressure value of the water pump 3 at the water inlet of the controller 2 within the time T, and mark it as , y represents the number of the pressure value of the water outlet of water pump 3 within time T, , is a positive integer;

[0076] It should be noted that the pressure value of the water outlet of the water pump 3 can be obtained through the first water pressure information acquisition module 7. The principle of acquisition is that the first water pressure information acquisition module 7 is installed on the surface of the water pipe A. When the water pump 3 starts to pump water, the first water pressure information acquisition module 7 converts the collected data into an electrical signal, and obtains the pressure value of the water outlet of the water pump 3 through processing. It should be noted that the first water pressure information acquisition module 7 includes a pressure sensor, a liquid level sensor, an ultrasonic liquid level sensor, etc., which are not specifically limited here. It should also be noted that the pressure value of the water outlet of the water pump 3 obtained within the time T is obtained at regular intervals. It can be the pressure value of the water outlet of the water pump 3 obtained every 1 minute within the time T, or it can be the pressure value of the water outlet of the water pump 3 obtained every 1 second within the time T, which is not specifically limited.

[0077] S2. Obtain the pressure value of the water outlet of the water pump 3 at the controller 2 within the time T and mark it as , y represents the number of the pressure value of the water outlet of pump 3 within time T, , is a positive integer;

[0078] It should be noted that the pressure value of the water outlet of the water pump 3 can be obtained through the second water pressure information acquisition module 9. The principle of acquisition is that the second water pressure information acquisition module 9 is installed on the water pipe B10. When the water pump 3 starts to discharge water, the second water pressure information acquisition module 9 converts the collected data into an electrical signal, and obtains the pressure value of the water outlet of the water pump 3 through processing. It should be noted that the first water pressure information acquisition module 7 includes a pressure sensor, a liquid level sensor, an ultrasonic liquid level sensor, etc., which are not specifically limited here. It should also be noted that the pressure value of the water outlet of the water pump 3 obtained within the time T corresponds to the pressure value of the water pump 3 suction port mentioned above. For example, the pressure value of the water outlet of the water pump 3 is obtained once every 1 minute or once every 1 second, which is consistent with the previous frequency of obtaining the pressure value of the water pump 3 suction port.

[0079] S3. Calculate the pressure value of the water outlet of pump 3 within time T. The standard deviation of , standard deviation The calculation formula is:

[0080]

[0081] in, is the pressure value of the water outlet of pump 3 within time T The average value of is obtained as: ;

[0082] S4. Calculate the pressure value at the outlet of pump 3 within time T. The standard deviation of , standard deviation The calculation formula is:

[0083]

[0084] in, is the pressure value of the water outlet of pump 3 within time T The average value of is obtained as: ;

[0085] S5, the pressure value of the water outlet of water pump 3 within T time Standard deviation The pressure value of the water outlet of pump 3 within T time Standard deviation Get the water pressure differential coefficient. The expression of the water pressure differential coefficient is: ;

[0086] It can be seen from the expression that the smaller the water pressure differential coefficient, the higher the stability of the entire intelligent mixing device body 4 during use, indicating that the quality of soda water prepared by the entire intelligent mixing device body 4 during use is better; the larger the water pressure differential coefficient, the lower the stability of the detection of the entire intelligent mixing device body 4 during use, indicating that the quality of soda water prepared by the entire intelligent mixing device body 4 during use is more likely to have problems.

[0087] Water outlet deviation coefficient: refers to the difference between the water flow rate sent out by the water outlet of the water pump 3 and the water flow rate entering the soda water mixing nozzle 5; because the function of the soda water mixing nozzle 5 is to convert the incoming water flow rate into water mist through the nozzle; if the difference between the water flow rate sent out by the water outlet of the water pump 3 and the water flow rate entering the soda water mixing nozzle 5 is too large, it is very likely that the water output of the water pump 3 meets the standard, but the water flow rate entering the soda water mixing nozzle 5 does not meet the standard, resulting in the water mist finally generated by the soda water mixing nozzle 5 failing to meet the preset standard, thereby causing the prepared soda water to not meet expectations, resulting in a lot of waste.

[0088] Therefore, it is very important to ensure that the water flow rate of water delivered by the water outlet of the water pump 3 is consistent with the water flow rate entering the soda water mixing nozzle 5.

[0089] The logic for obtaining the outlet deviation coefficient is as follows:

[0090] S1. Obtain the water flow rate at the outlet of pump 3 of the entire mixing equipment within time T and mark it as , z represents the number of the water flow rate at the outlet of pump 3 within time T, , is a positive integer;

[0091] S2. Obtain the water flow rate of the entire mixing device entering the soda water mixing nozzle 5 within time T, and mark it as , z represents the number of water flow entering the soda water mixing nozzle 5 within the time T, , is a positive integer;

[0092] It should be noted that the water flow at the outlet of the water pump 3 can be collected by the first water flow collection module 11, which is installed on the water pipe C12; the water flow entering the soda water mixing nozzle 5 is collected by the second water flow collection module 13, and the components installed in the water flow collection module may include liquid mass flow sensors, ultrasonic flow sensors, electromagnetic flow sensors, turbine flow sensors, etc., which are not specifically limited here.

[0093] S3. Calculate the outlet deviation coefficient. The calculation expression is: , where is the outlet deviation coefficient.

[0094] It can be seen from the expression that the water outlet deviation coefficient indicates that the higher the stability of the entire intelligent mixing device body 4 during use, the better the quality of soda water prepared by the entire intelligent mixing device body 4 during use; the larger the water outlet deviation coefficient, the lower the stability of the detection of the entire intelligent mixing device body 4 during use, and the more likely there will be problems with the quality of soda water prepared by the entire intelligent mixing device body 4 during use.

[0095] The external environment information includes the instability coefficient of the power supply voltage of the intelligent hybrid device body 4 when in use;

[0096] The instability coefficient of the power supply voltage refers to the stability of the voltage during the use of the hybrid device. If the voltage stability of the device is poor during use, it will lead to many negative effects, including the following:

[0097] Poor condenser performance: Voltage fluctuations may cause the condenser to be unable to maintain a stable temperature when cooling the water, thereby affecting the quality of the prepared soda water. The taste and quality of soda water are usually affected by temperature, so unstable voltage may lead to inconsistent beverage quality. At the same time, unstable voltage may cause the condenser to consume too much power, which may increase the energy cost of equipment operation.

[0098] Equipment failure: Unstable voltage can cause damage to equipment electronic components, motors, control systems, etc., leading to equipment failure or premature failure, which may require expensive repair or replacement of the equipment.

[0099] Quality issues: Voltage fluctuations may cause the equipment to be unable to maintain stable working conditions when making soda water. The taste and quality of soda water are usually affected by water temperature, air pressure and mixing ratio. Unstable voltage may lead to inconsistent beverage quality.

[0100] Reduced production efficiency: Unstable voltage may cause unstable equipment operation, thereby reducing production efficiency. This may lead to increased downtime in the production process and reduced equipment output.

[0101] Safety risks: Unstable voltage can cause problems with the equipment’s control system, increasing safety risks. For example, the equipment may not be able to properly control the CO2 gas supply, causing pressure to rise and potentially triggering a dangerous situation.

[0102] Energy waste: Voltage fluctuations may cause equipment to consume excessive power during operation, increasing energy costs.

[0103] Therefore, the stability of the power supply voltage is very important.

[0104] The logic for obtaining the power supply voltage instability coefficient is as follows:

[0105] S1. Obtain the stable voltage value range of the entire hybrid device within T time and mark the range as ,and ;

[0106] It should be noted that, in actual usage scenarios, the optimal voltage range of the entire mixing device is determined by collecting the stable voltage range of the mixing device when it is stable without any faults and the taste of the produced soda water meets the merchant's expectations.

[0107] S2. Obtain the actual supply voltage value of the entire hybrid device at different times during the T time, and calibrate the actual supply voltage value as , x represents the number of the actual power supply voltage value of the hybrid device at different times during the time T, , is a positive integer;

[0108] It should be noted that in the hybrid device, a dedicated monitoring circuit is installed to monitor the power supply voltage of the hybrid device in real time. This monitoring circuit usually includes a voltage sensor or a monitoring chip, which can measure the power supply voltage in real time and output it as a voltage value or analog signal;

[0109] S3, will be Voltage values outside the range are recorded as , s is the pressure of the probe at different test points Numbers outside the range, , is a positive integer;

[0110] S4. Calculate the power supply voltage instability coefficient. The calculation expression is: , where is the power supply voltage instability coefficient.

[0111] It can be seen from the calculation that the smaller the power supply voltage instability coefficient of the entire mixing device within the time T, the higher the stability of the entire intelligent mixing device body 4 during use, and the better the quality of soda water prepared by the entire intelligent mixing device body 4 during use; the larger the power supply voltage instability coefficient, the lower the stability detected during use of the entire intelligent mixing device body 4, and the more likely there will be problems with the quality of soda water prepared by the entire intelligent mixing device body 4 during use.

[0112] The water pressure differential coefficient , outlet deviation coefficient And the power supply voltage instability coefficient Conduct comprehensive processing, establish a processing model, and generate evaluation coefficients , the expression is:

[0113]

[0114] Where, are the preset proportional coefficients of water pressure differential coefficient, water outlet deviation coefficient and power supply voltage instability coefficient, respectively, and All greater than 0;

[0115] The obtained evaluation coefficient is compared with the evaluation coefficient threshold. If the evaluation coefficient is greater than the evaluation coefficient threshold, it means that the mixing equipment has failed. In order to prevent the quality of the produced soda water from being affected, the working state of the mixing equipment is immediately stopped to prevent further losses.

[0116] If the evaluation coefficient is less than the evaluation coefficient threshold, it proves that the mixing device is in good working condition and can continue to prepare soda water without any treatment of the mixing device.

[0117] The present invention is provided with a controller 2, a water pump 3, a soda water mixing nozzle 5, and a carbon dioxide air inlet 6. Water is pumped out through the water pump 3, and the original water flow is converted into water mist through the soda water mixing nozzle 5. Then, carbon dioxide is introduced through the carbon dioxide air inlet 6 at the same time to react and generate soda water. This makes the efficiency and effect of preparing soda water better and makes the reaction between carbon dioxide and water more complete.

[0118] The present invention establishes an evaluation coefficient of the device by collecting the water pressure difference coefficient, the water outlet deviation coefficient and the power supply voltage instability coefficient, and compares the evaluation coefficient with the evaluation coefficient threshold to determine whether the soda water prepared by the mixing device meets the merchant's expectations. If the evaluation coefficient is greater than the evaluation coefficient threshold, it proves that the soda water produced by the mixing device at this time does not meet the merchant's expectations, and the working state of the mixing device needs to be stopped in time.

The preset parameters in the formulas are set by technicians in this field according to actual conditions.
