Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Before explaining the present invention in detail, a brief description of the control process of the present invention relating to the dosing accuracy will be given. The system corresponding to the control process of the feeding precision is used as the equipment center control of the feeding process and can be connected with various kitchen equipment, and comprises a batching device, a feedback device, a reference device and the like, when the batching device, the feedback device and the reference device are connected to the equipment center control, the batching device, the feedback device and the reference device can adopt the form of a control management platform, the batching device can be connected with the batching device through the equipment center control, a batching instruction can be sent to the batching device so as to control the batching device to execute the feeding action, the feeding feedback signal sent by the feedback device can be obtained after the batching device executes the feeding action through the connection of the equipment center control and the feedback device, the batching information of the batching device can be obtained through the connection of the feedback device and the batching device, the feedback signal is processed into a batching feedback signal, and the feedback signal can be directly sent to the equipment center control, the feedback signal is processed into the batching feedback signal by the central control of the equipment, the data source sent by the reference device can be obtained by connecting the central control of the equipment with the reference device, so that the central control of the equipment can compare the batching feedback signal with the reference signal in the data source according to the batching feeding, the batching feeding precision is calculated, and if the batching feeding precision has deviation, the batching feeding precision can be controlled to be adaptively adjusted when the batching device is used for next batching, so that the batching feeding precision is accurate. It should be noted that, in order to facilitate the control of the batching process, the central control of the equipment may be embedded in the service end corresponding to the batching equipment, and the feeding precision may be directly controlled by the service end corresponding to the batching equipment.
The embodiment of the invention provides a control method of feeding precision, which can be applied to a service end side corresponding to a batching device, and comprises the following steps:
101. and receiving a batching instruction, and controlling batching equipment to execute a feeding action according to the batching instruction.
In the process of making dishes, the kitchen equipment puts seasonings for making dishes into the batching equipment, so that the batching equipment controls the putting of various seasonings at the blanking time set by the electronic menu. However, since the types and the putting sequence of seasonings required by different dishes and the grams of seasonings to be put in are different, it is necessary to control the batching device to put in seasonings with different grams according to the putting sequence in the dish making process.
The method comprises the steps that a batching instruction is set by a device center control based on an electronic menu and used for controlling seasonings to execute feeding actions according to corresponding feeding time, specifically, in the process of controlling the batching device to execute the feeding actions according to the batching instruction, seasoning feeding information of the batching device in the cooking process can be obtained according to a pre-configured electronic menu, the seasoning feeding information can comprise seasoning types, seasoning feeding amounts, seasoning feeding sequences and the like required by dishes, batching instructions are generated according to the seasoning feeding information, the seasoning feeding amounts, the batching time, the batching speed and the like of the batching device are controlled by the batching instruction, for example, for an electronic menu of tomato eggs, the required seasoning feeding information comprises 4 seasonings, salt, sugar, oil consumption and chicken essence, and the feeding time sequence and the feeding gram number of the 4 seasonings are sugar 5g (1 min 10 sec) -oil consumption 5g (1 min 30 sec) -salt 2g- (1 min 35 sec) chicken essence 2g (2 min 5 sec), the ingredient instructions generated based on the seasoning throwing information can control the seasonings to perform the throwing operation at the corresponding time points according to the throwing time sequence.
The execution main body of the embodiment of the invention is an equipment central control end, and because the types of seasonings required by different dishes, the required putting sequence and the gram number of the put seasonings are different, an electronic menu can be obtained and analyzed through the equipment central control to determine the putting information of each seasoning in the dish making process of the batching equipment, such as the putting sequence, the putting gram number and the like of the seasonings, wherein the seasonings mainly comprise but are not limited to salt, soy sauce, vinegar, monosodium glutamate, sesame oil and the like which can play a seasoning role on the dishes, and further, a batching instruction is generated according to the putting information of each seasoning to control the batching equipment to execute the throwing action. Under a general condition, dishes ordered by a user after entering a restaurant can be sent to a background in a form of order information formed by dish ordering equipment, the background sends the order information to a cloud server to search and configure an electronic menu required by making each dish, and extracts batching information required to be executed by batching equipment in the electronic menu to generate a batching instruction, and the batching equipment is controlled to execute a feeding action according to the batching instruction.
102. And when the completion of the feeding action is detected, a feeding feedback signal is obtained.
Considering that the feeding precision of the batching device is influenced by environmental factors, such as abrasion of the batching device and humidity in the batching device, the feeding information executed by the batching device may have errors, for example, a batching instruction controls the batching device to execute feeding of 2g of chicken essence, the actual batching device executes feeding of 1.5g of chicken essence, and the actual batching device does not reach the actual feeding of chicken essence, so that the feeding precision is inaccurate, and the taste of dishes are influenced. In the related technology, the feeding amount of the seasonings can be adjusted in the process of manually feeding the ingredients by the ingredients equipment, so that the feeding precision of the ingredients equipment is improved. However, the adjustment of the feeding amount of the batching equipment is difficult to be successfully adjusted at one time, the feeding precision is often required to be calibrated for many times, the feeding precision is difficult to be ensured to reach the cooking requirement, and the cooking experience of dishes is influenced.
Because the batching equipment is not a one-time operation for executing the feeding action, the dish making process may involve multiple feeding actions, and the feeding precision of the batching equipment is continuously changed along with the accumulation of the feeding times or the influence of factors such as environment and the like. Therefore, according to the embodiment of the invention, the feeding feedback signal calculated based on the current feeding action can be obtained after the batching device executes the feeding action, the feeding feedback signal is equivalent to the difference value formed by the expected feeding amount and the actual feeding amount, and can reflect the feeding precision of the batching device, the expected feeding amount is the feeding amount of the recorded seasonings in the electronic menu, and the actual feeding amount is the feeding amount detected by the batching device in the feeding process. Under the ideal condition, the actual material feeding amount should keep unanimous with the anticipated material feeding amount, just so can guarantee the culinary art effect of dish, and if the actual material feeding amount is less than anticipated material feeding amount, then show dispensing equipment's material feeding precision and do not reach the culinary art demand, need adjust actual material feeding amount to make actual material feeding amount approach and anticipated material feeding amount, with the accuracy of guaranteeing dispensing equipment material feeding precision.
103. And adjusting the feeding precision of the batching equipment according to the feeding feedback signal.
In the embodiment of the present invention, although the feeding feedback signal can reflect the feeding accuracy of the batching device, the feeding accuracy is not caused by a single feeding action, the feeding accuracy of the batching device can be adjusted by combining a reference feeding signal of the batching device, and the feeding accuracy of the batching device can also be adjusted by combining feeding parameters of the batching device, the reference feeding signal is determined based on the historical feeding accuracy of the batching device, and can reflect the change situation of the feeding accuracy of the batching device after multiple feeding actions, the feeding parameters include the feeding times, the feeding speed, and the like, and since the loss situation of the feeding accuracy is usually recorded when the batching device leaves a factory, the loss situation can be determined by combining the feeding parameters.
It can be understood that, in order to adjust the feeding precision of the batching apparatus, the central control apparatus records the historical feeding precision, the feeding parameters and the like when the batching apparatus performs the feeding action each time, and stores the historical feeding precision, the feeding parameters and the like in the data source, and then after obtaining the feeding feedback signal, may call corresponding target data from the data source based on the feeding feedback signal, and adjust the feeding precision of the batching apparatus according to the target data and the feeding feedback signal, where the target data may also be in the form of a signal, and may represent the historical feeding precision of the batching apparatus, and the target data may also be the loss amount of the feeding precision, and may represent the use state of the batching apparatus.
Compared with the mode that manual intervention is needed to adjust the seasoning feeding precision in the prior art, the control method for the feeding precision controls the batching equipment to execute the feeding action according to the batching instruction by receiving the batching instruction, acquires feeding feedback information when the feeding action is detected to be executed, and adjusts the feeding precision of the feeding equipment according to the feeding feedback signal to realize automatic adjustment of the feeding precision, does not need manual intervention and calibration, improves the cooking experience while ensuring accurate feeding precision, and indirectly solves the problem that the feeding precision is easily influenced by the external environment.
The control is equivalent to an intelligent kitchen all-in-one machine device in the equipment, as shown in fig. 1, the intelligent kitchen all-in-one machine device is respectively connected with the batching device, the feedback device and the reference device, and the intelligent kitchen all-in-one machine device can adjust the feeding precision of the batching device based on feeding feedback signals sent by the feedback device and feeding reference signals sent by the reference device, so that the automatic adjustment of the feeding precision in the feeding process is realized, and the accuracy of the feeding precision is improved.
Specifically, in the process of acquiring the feeding feedback signal, expected feeding information of the batching equipment before the feeding action is executed and actual feeding information of the batching equipment after the feeding action is executed can be respectively extracted, the expected feeding information can be obtained by intercepting from a cooking step recorded in an electronic menu, the actual feeding information can be obtained by detecting a difference value formed by the amount of seasoning before and after the feeding action of the batching equipment, and the expected feeding information and the actual feeding information are further compared to obtain the feeding feedback signal. The expected feeding information and the actual feeding information are compared, difference data formed before and after the batching equipment performs the feeding action is calculated, and feeding feedback signals are obtained based on the difference data. For example, the expected feeding amount of salt recorded in the electronic menu is 3g, the seasoning amount before the dispensing equipment performs the feeding action is 10g, and the seasoning amount after the dispensing action is 7.5g, the actual feeding amount of the seasoning salt is 2.5g, the difference value between the expected feeding amount and the actual feeding amount is 0.5g, and the feedback signal is a signal formed by the difference value between the feeding amounts of 0.5 g.
It can be understood that the feeding feedback signal records difference data generated in the feeding process, for example, a feeding amount difference value and a feeding time difference value, where the larger the feeding amount difference value is, the larger the difference between the actual feeding amount and the expected feeding amount is, the lower the feeding accuracy is, the larger the feeding time difference value is, the limited seasoning feeding speed is, the slow feeding operation is, and the lower the feeding accuracy is. In order to facilitate analysis of feeding feedback signals, feeding feedback signals suitable for different difference data are set by dividing feeding quantity difference values and/or feeding time difference values and performing precision grade division on the difference data by utilizing a pre-established mapping relation, and the higher the precision grade is, the smaller the amplitude corresponding to the feeding feedback signals is; the pre-established mapping relation is a mapping relation between a feeding amount difference value and/or a feeding time difference value and a precision grade, and the larger the difference value is, the lower the precision grade is. For example, the pre-established mapping relationship is the mapping relationship between the difference value of the feeding amount and the difference value of the feeding time and the precision grade, the difference value of the feeding amount is 0-1g, the difference value of the feeding time is 1s, the corresponding precision grade is A grade, the corresponding amplitude of the feeding feedback signal is minimum, the feeding precision is higher, the feeding quantity difference is 1g-3g, the feeding time difference is 3s, the corresponding precision grade is B grade, the corresponding amplitude of the feeding feedback signal is in the middle, the feeding precision is higher, the feeding quantity difference is 3g-5g, the feeding time difference is 5s, the corresponding accuracy grade is C grade, the corresponding amplitude of the feeding feedback signal is large, and in the practical application scene, more precision levels, and the range of the difference of the feeding amount and the range of the difference of the feeding time corresponding to different precision levels can be set, and are not limited herein.
Further, considering that different cooking manners are required for making different dishes by kitchen equipment, and different cooking equipment, cooking power and cooking time may be required, which results in different environmental information when the ingredients are fed by the ingredients equipment, for example, in the case of cooking with big fire, the cooking equipment is usually a wok, and the firepower required for controlling the cooking power is increased, which results in higher hot air in the cooking process and heavier moisture, which affects the feeding accuracy of the ingredients equipment. Here, the feeding feedback signal may further add environmental information of the batching device, for example, after a feeding difference value formed by an expected feeding amount and an actual feeding amount is obtained, an influence factor of the feeding difference value may be set based on the environmental information, especially, an influence factor related to humidity, for example, an increase in cooking power, a cooking function, etc. may increase environmental humidity, a reduction in cooking power, an exhaust function, etc. may decrease environmental humidity, and for an influence factor related to humidity increase in the environmental information, a certain influence may be generated on the actual feeding amount, and further, the feeding difference value may be influenced. Therefore, the higher the influence factor related to humidity increase, the greater the influence on the feeding amount difference value is, and the accuracy of the feeding feedback signal can be improved by adding the influence factor related to humidity into the feeding feedback signal. Specifically, a humidity sensor arranged in the batching plant can be used for detecting a temperature value or a humidity value of the batching plant in the feeding process.
Particularly, in the process of adjusting the feeding precision of the batching equipment according to the feeding feedback signal, a feeding reference signal of the batching equipment can be preset, the feeding reference signal can reflect the historical feeding precision of the batching equipment, the historical feeding precision of the batching equipment can be obtained, the feeding reference signal of the batching equipment is preset according to the historical feeding precision, the feeding precision is influenced by difference data formed in each feeding process of the batching equipment, the historical feeding precision records the ratio of the difference data formed in each feeding process to the expected feeding quantity, the expected feeding quantity is the fixed feeding quantity in the electronic menu, the difference between the actual feeding quantity and the expected feeding quantity can reflect the feeding accuracy of the equipment, the feeding feedback signal is further compared with the feeding reference signal, and if the amplitude difference formed by the feeding feedback signal and the feeding reference signal is larger than a preset threshold value, the method includes the steps of determining that the feeding precision of the current batching equipment generates a large deviation, further adjusting the feeding precision of the batching equipment according to an amplitude difference value, and determining that the feeding precision of the current batching equipment generates a small deviation if the amplitude difference formed by a feeding feedback signal and a feeding reference signal is less than or equal to a preset threshold value.
In the process of presetting feeding reference signals of the batching equipment according to historical feeding precision, as an implementation mode, a floating interval corresponding to the historical feeding precision can be determined by analyzing the historical feeding precision, the floating interval reflects the range of historical feeding quantity difference, and for feeding precision exceeding the range of the feeding quantity difference, the feeding precision is indicated to generate larger deviation and needs to be adjusted, the feeding precision which does not exceed the feeding quantity difference value range indicates that the feeding precision is in the allowable error range, the feeding precision does not need to be adjusted, the feeding reference signal of the batching equipment is preset according to the average value of the feeding precision in the floating interval, for example, the average value of historical feeding precision is in the range of the allowable feeding quantity difference value of 0.3g, and the feeding reference signal of the batching equipment is set to be a signal formed by the feeding quantity difference value of 0.3 g; as another embodiment, the feeding precision of the last feeding action performed closest to the current feeding scene may be determined by analyzing the historical feeding precision, and the feeding reference signal of the batching plant may be preset according to the feeding precision of the last feeding action performed closest to the current feeding scene, for example, the feeding precision of the last feeding action is set to be within a range that the feeding quantity difference is 0.2g, and the feeding reference signal of the batching plant is set to be a signal formed by a feeding quantity difference of 0.2 g.
Particularly, in the process of adjusting the feeding precision of the batching equipment according to the amplitude difference, the seasoning feeding information required to be adjusted by the batching equipment can be determined according to the amplitude difference, so that the actual feeding information approaches to the expected feeding information, the difference data formed in the feeding process is reduced, and the batching equipment is further controlled to execute the feeding action according to the seasoning feeding information required to be adjusted. In an actual application scenario, if the feeding accuracy of the batching device exhibits a decreasing rule or has a decreasing trend along with the change of feeding parameters, for example, the feeding accuracy of the batching device decreases by a certain value every time the feeding frequency increases by a fixed number, the compensation amount can be set for the use condition of the batching device, and similarly, if the feeding accuracy of the batching device exhibits a decreasing rule or has a decreasing trend along with the change of the feeding environment, for example, the humidity of the feeding process increases, the feeding accuracy of the batching device decreases, and the compensation amount for different environment scenarios can be set for the use environment of the batching device.
It can be understood that, considering the wall hanging situation when different seasoning types are fed, the batching device can use different feeding speeds for different seasoning types in the process of executing feeding actions, for example, liquid seasonings such as soy sauce, vinegar and the like can use a fast feeding speed, solid seasonings such as sugar, chicken essence and the like can use a medium feeding speed, and viscous liquids such as oil consumption, water starch and the like can use a slow feeding speed, so that feeding errors can be reduced to a certain extent.
In order to illustrate the specific implementation process of the above embodiment, the following application scenarios are given, but not limited to:
taking the use of the batching equipment as an example, the intelligent kitchen all-in-one machine equipment can send batching instructions to the batching equipment, after the batching equipment performs the feeding action, the batching equipment can generate a feedback signal, the feeding feedback signal can be a pulse signal, the feedback signal is processed by a feedback device to generate a feeding feedback signal, the feeding feedback signal is sent to the intelligent kitchen all-in-one machine equipment, the reference device continuously accumulates feeding parameters every time during the feeding process performed by the batching equipment to form a reference data source of the feeding process, data in the basic data source is formed into a feeding reference signal and sent to the intelligent kitchen all-in-one machine equipment, an adaptive calibration algorithm is embedded in the intelligent kitchen all-in-one machine equipment, the current feeding precision condition of the batching equipment is calculated by utilizing the obtained feeding feedback signal and the feeding reference signal, and if the feeding precision exceeds a deviation range, the intelligent kitchen all-in-one machine can control the batching equipment to automatically correct the feeding precision when feeding next time, wherein the self-adaptive adjustment can adjust the feeding reference signal as a basis and can also directly adjust the difference data formed in the feeding process to be the same as the reference data of the reference feeding signal.
Above-mentioned throw the control method of material precision, can throw the material in-process at the dispensing equipment, need not artifical intervention to throw the adjustment of material precision, promoted culinary art greatly and experienced the sense and indirectly solved throw the material precision and receive the problem that external environment influences easily.
