Detailed Description

In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments that can be derived from the embodiments given herein by a person of ordinary skill in the art are intended to be within the scope of the present disclosure.

In order to effectively control a teaching video and improve user experience, the application provides teaching video control equipment, a video control method, a video control device, equipment and a medium.

In order to effectively control the teaching video, the teaching video comprises a plurality of steps, and the playing time length corresponding to each step is correspondingly stored. In the present application, the teaching video control apparatus includes: the communication device and the controller are used for judging whether the playing of the current step is finished according to the playing duration corresponding to each step when the teaching video control device controls the playing of the teaching video, and controlling the teaching video to pause if the completion of the playing of the current step is detected. And acquiring an external sensor with a changed parameter value according to the parameter value received by the communicator, judging whether the external sensor is a trigger sensor corresponding to the next step of the current step, if so, determining that the current step is finished if the parameter value sent by the external sensor meets a preset playing condition, and controlling the teaching video to continue playing. If the teaching video control device is an intelligent device such as a mobile terminal or a smart television, pausing or playing of a teaching video is performed through a display of the teaching video control device, and if the teaching video control device is a processor installed on a use tool, pausing or playing of the teaching video is performed through a mobile terminal connected with the teaching video control device in a control mode.

Fig. 1 is a schematic structural diagram of a teaching video control device 100 provided in the present application, and as shown in fig. 1, the teaching video control device 100 includes:

the communicator 101 is used for receiving parameter values sent by an external sensor;

a controller 102, the controller 102 configured to:

In the present application, the teaching video control device 100 includes a communicator 101 and a controller 102, and the teaching video control device may be an intelligent device such as a mobile terminal or a smart television, or may be a processor mounted on a tool.

When the teaching video is watched, after the teaching video corresponding to the current step is played, a novice can carry out operation practice according to the teaching content of the teaching video of the current step. Therefore, in the application, it may be determined whether the teaching video corresponding to the current step is played completely, and if it is determined that the teaching video corresponding to the current step is played completely, the teaching video is paused. If the teaching video control device is an intelligent device such as a mobile terminal or an intelligent television, a controller of the teaching video control device controls a display to pause playing. If the teaching video control equipment is a processor installed on a use tool, the controller of the teaching video control equipment controls the connected mobile terminal to pause playing.

In addition, in the application, in order to control the teaching video, the teaching video control device may receive a parameter value sent by an external sensor, and the specific teaching video control device is provided with a communicator which receives the parameter value sent by the external sensor. In the present application, the installation position of the external sensor includes: chopping boards, kitchen knives or seasoning box bottoms and the like. And because the steps in the teaching video are different, the required operations are also different, so the corresponding trigger sensors for triggering the next step are also different.

Since the external sensor continuously transmits the parameter value, in the present application, the external sensor that has the transmitted parameter value changed may be acquired first, and if there is an external sensor that has a changed parameter value, it is determined whether the external sensor is a trigger sensor for the next step of the current step, that is, it is determined whether the external sensor is a sensor required for triggering the next step of the current step.

Specifically, if the teaching video control device is a smart television or a mobile terminal, in the present application, the external sensor is determined according to the identification information of the sensor carried by the external sensor when sending the parameter value, and then whether the external sensor is the trigger sensor of the next step is determined, that is, the external sensor is determined according to the received identification information and the identification information corresponding to the trigger sensor of the next step stored in advance.

If the teaching video control equipment is a processor installed on a use tool, the difference of interfaces is used for determining which external sensor is the external sensor when the external sensor and the teaching video control equipment transmit parameter values in the application, and then whether the external sensor is the trigger sensor of the next step is judged. That is, in the present application, the teaching video control device receives parameter values sent by different external sensors through different interfaces. However, since the number of interfaces of the teaching video control device is limited, and there may be a case where the number of external sensors exceeds the number of interfaces, and there is a case where a plurality of external sensors perform transmission of parameter values through the same interface, in the present application, in order to accurately determine which external sensor receives a parameter value, the teaching video control device acquires the parameter value transmitted by the external sensor connected to the interface in such a manner that the teaching video control device sequentially accesses different external sensors at preset time intervals, the external sensor transmits the parameter value of the external sensor to the teaching video control device after receiving access information of the teaching video control device, and when different external sensors perform transmission of parameter values through the same interface, determines which external sensor the sensor that has a parameter value change is based on which external sensor has been accessed, and then judging whether the external sensor is the trigger sensor of the next step or not. In the present application, the time interval for the teaching video control device to access the external sensors through the interface is short, that is, the parameter value sent by each external sensor can be continuously acquired.

This sensor is referred to herein as a trigger sensor since it can trigger the next step of the instructional video playback. When the external sensor and the teaching video control device transmit the parameter values through the interface, the parameter values can be transmitted in a Bluetooth mode, and the parameter values can also be transmitted in other modes, so that the parameter values are specifically transmitted without limitation.

Because only the use tool provided with the external sensor is used, the parameter value of the external sensor can be changed, if the external sensor is the trigger sensor of the next step of the current step, whether the preset playing condition is met or not is determined according to the parameter value sent by the external sensor, and misoperation is distinguished. If the preset playing condition is determined to be met according to the parameter value sent by the external sensor, the operation execution required to be executed in the current step is completed, and the teaching video is controlled to be continuously played, namely the teaching video corresponding to the next step is continuously played. If the teaching video control device is an intelligent device such as a mobile terminal or an intelligent television, the controller controls the display to continuously play the teaching video of the next step. If the teaching video control equipment is a processor installed on a using tool, the controller controls the mobile terminal connected with the teaching video control equipment to continuously play the teaching video of the next step. Wherein, the teaching video control device and the mobile terminal can be connected in a Bluetooth mode.

In addition, in order to play the teaching video of the next step, in the present application, the triggering sensor of the next step may be a sensor installed on a required tool when the teaching video of the current step is executed, or may also be a sensor installed on a specific tool. For example, if the required tool is a seasoning box for placing salt when executing the teaching video of the current step, and the teaching video of the next step can also be played through an acceleration sensor mounted on the kitchen knife, the trigger sensor of the next step of the current step may be a pressure sensor mounted under the seasoning box for placing salt, or an acceleration sensor mounted on the kitchen knife.

For example, the content played in the current teaching video is "cut two garlic", and normally, when the two garlic is cut, the number of times of the cutting knife is within a certain number range, in the present application, if it is determined that the preset playing condition is met according to the parameter value sent by the acceleration sensor installed on the cutting knife, it indicates that the number of times of the cutting knife is within the certain number range, and it indicates that the operation required to be executed in the current step is completed.

The teaching video control device can intelligently determine whether the teaching video corresponding to the current step is played completely, if the playing is completed, the teaching video is controlled to be paused and played, and the teaching video can be intelligently controlled to be continuously played, so that the pausing and the playing of the teaching video are effectively controlled, and the problem that the operation is too complicated due to the fact that the teaching video is controlled to be played and paused by a user when the teaching video is controlled is effectively solved.

In order to effectively control the teaching video, on the basis of the above-described embodiments, in an embodiment of the present application, the controller is configured to:

if the parameter value sent by the external sensor is within a preset first numerical value range, determining that a preset playing condition is met; or

Determining the times of the parameter value change of the external sensor according to other parameter values received within a set time length before the parameter value is received, and if the times are within a preset time range, determining that a preset playing condition is met; or

And determining a target curve of the changed parameter value of the external sensor according to other received parameter values within a preset time length before the parameter value is received, and determining that a preset playing condition is met if the target curve is similar to a preset curve.

Since the playing conditions corresponding to different steps are different, in the present application, the manner of determining whether the preset playing conditions are met is different for different steps. Specifically, when determining whether the preset playing condition is met, the method may determine directly according to the received parameter value sent by the external sensor, and if the parameter value is within a preset first numerical value range, determine that the trigger sensor in the next step of the current step meets the preset playing condition. For example, if the content of the teaching video is to add 2g of salt, the external sensor with the changed corresponding parameter value is a pressure sensor installed under a seasoning box for placing the salt, and after the parameter value sent by the external sensor is received to be changed, whether the external sensor is the corresponding pressure sensor is judged, if yes, the parameter value sent by the pressure sensor before the parameter value is changed is known, and the reduced pressure value of the salt is also within a certain pressure range, and when the received parameter value is determined to be within a preset first value range, it can be determined that the preset playing condition is met.

If the trigger sensor of the next step is a specific sensor installed on the tool, for example, the trigger sensor of the next step is an acceleration sensor installed on a handle of a kitchen knife, and the teaching video playing manner of the next step is to rotate the kitchen knife by a preset angle in a preset direction, the parameter value sent by the acceleration sensor is fixed before the change of the acceleration sensor occurs, and after the handle is rotated by the preset angle in the preset direction, the parameter value sent by the acceleration sensor is within a certain parameter value range. Therefore, in the present application, if the triggering sensor of the next step is a sensor installed on a specific tool, and the parameter value sent by the external sensor is within a preset value range, it is determined that the preset playing condition is satisfied. And through the sensor installed on the specific use tool, the teaching video of the next step can be played, and the teaching video of the previous step can be played again. For example, the teaching video of the previous step can be played by rotating the tool handle to the left, and the teaching video of the next step can be played by rotating the tool handle to the right. Specifically, how to trigger the teaching video in the previous step to play is not limited herein.

In addition, when determining whether the preset playing condition is met, the determination may also be performed according to other parameter values received within a preset time length before the received parameter value. Specifically, the set time length may be preset. In the method, the number of times of the parameter value change sent by the external sensor within the set time length is determined, and if the determined number of times is within the preset number of times, the condition that the preset playing condition is met is determined.

Specifically, in this application, the teaching video under this condition can be a video for preparing dishes, and because the number of times that the kitchen knife is cut from top to bottom is generally uniform when preparing dishes, but the kitchen knife can make the parameter value of external sensor change when changing the direction, therefore in this application, can confirm whether the number of times that the parameter value changes is in the threshold value scope of predetermined number of times. In addition, the external sensor can be an acceleration sensor arranged on the chopping board, can also be an acceleration sensor arranged on the chopping knife, and can also be determined by the acceleration sensor arranged on the chopping board and the acceleration sensor arranged on the chopping knife together.

Specifically, under the ordinary condition, after cutting the dish, all can put down the kitchen knife, place the dish that has cut in the container of putting the dish through the kitchen knife to also can have the condition that the hand was put loose down to the short time midway of cutting the dish, put down the kitchen knife, if the parameter value that sends through the acceleration sensor of installation on the kitchen knife or the acceleration sensor of installation on the chopping board alone confirms the number of times of cutting the dish, then cause the error easily, consequently can be through the angle that the acceleration sensor in the kitchen knife obtained, the cut-to-edge number of times of cutting the dish is denoised. When the controller determines the times of parameter value change through an acceleration sensor arranged on the chopping board, the following formula can be used for filtering.

Wherein, the times is the garlic cutting times detected by the current controller, and the times is the garlic cutting times detected by the current controller ₀ The last time the controller detects the garlic cutting times, the roll is the rolling angle of the rotation of the kitchen knife detected by the controller, and the threshold is the maximum value of the roll angle during vegetable cutting. Specifically, it is prior art to acquire the rotation angle in the preset direction through the acceleration sensor, and details are not repeated here.

In addition, when determining whether the preset playing condition is met, the determination may be performed according to a target curve determined by the parameter value, and if the teaching video corresponding to the current step is a teaching video of "mashing eggs", the determination may be performed according to this manner. Specifically, a target curve corresponding to the parameter value sent by the external sensor is determined according to other received parameter values within a preset time length before the received parameter value, if the determined target curve is similar to a preset curve, it indicates that the process of crushing eggs is being executed, and it is determined that preset playing conditions are met.

As can be seen from fig. 2a, the chopping board is provided with an RFID antenna, a reader/writer, an acceleration sensor, and a pressure sensor. As can be seen from fig. 2b, the pressure sensor is installed between the upper panel and the lower panel of the cutting board.

Fig. 3a is a schematic view of a kitchen knife provided in the embodiment of the present application, and fig. 3b is a schematic view of a sensor provided in the embodiment of the present application and installed in a local position of the kitchen knife.

As can be seen from fig. 3a, the acceleration sensor attached to the tool can acquire three angles of direction change, namely, roll angle (roll), pitch angle (pitch), and yaw angle (yaw). As can be seen from fig. 3b, the kitchen knife is provided with an acceleration sensor and an RFID tag. Specifically, the controller judges whether the cutter used by the novice in the cooking process is correct or not through the installed RFID tag.

Fig. 4a is a schematic view of a seasoning box provided in an embodiment of the present application, and fig. 4b is a schematic view of a mounting position of a pressure sensor provided in an embodiment of the present application.

As can be seen from FIG. 4a, in the embodiment of the present application, a seasoning box with 3 small size is taken as an example for illustration, and as can be seen from FIG. 4b, a pressure sensor can be installed at a position on a seasoning box mat where the seasoning box is placed, and whether a user puts a proper seasoning or not and whether the dosage of the seasoning is proper or not are detected through the pressure change condition detected by the pressure sensor on the seasoning box mat.

Fig. 5 is a schematic view of a tool according to an embodiment of the present disclosure. As can be seen from fig. 5, a cutting board, a kitchen knife and a seasoning box are required in the present application.

In order to effectively control a teaching video, on the basis of the above-described embodiments, in an embodiment of the present application, the controller is configured to:

and if the parameter value sent by the external sensor is within a preset first numerical range, determining that a preset playing condition is met through a set time length.

When determining whether the preset playing condition is met, the corresponding teaching video needs to be stir-fried, so that in the application, if the teaching video corresponding to the current step needs to be stir-fried, after determining that the parameter value sent by the external sensor is within the preset first numerical value range, and after the set duration, determining that the preset playing condition is met. Wherein the duration can be flexibly set according to the requirement.

For example, if the content of the teaching video playing corresponding to the current step is "pour eggs into a pan and stir-fry," it is determined that the preset playing condition is met after the parameter value sent by the external sensor is determined to be within the preset first numerical value range and the set duration. Specifically, if the playing content of the teaching video corresponding to the current step is 'pouring eggs into a pot and stir-frying', the external sensor is a pressure sensor installed on a chopping board, and the preset first numerical value range is a pressure value range. Because the pressure value sent by the pressure sensor can be continuously obtained on the chopping board, when the eggs are positioned on the chopping board and are not poured into the pot, the value of the pressure sensor is a fixed certain numerical value, and after the eggs are poured into the pot, the pressure value sent by the pressure sensor is within a certain numerical value range. The numerical range is a preset first numerical range corresponding to the content of teaching video playing in the current step of 'pouring eggs into a pot and stir-frying'.

In order to effectively control the teaching video, on the basis of the above embodiments, in an embodiment of the present application, the controller is further configured to:

and if an instruction for playing the teaching video is received, controlling to play the teaching video in the corresponding step.

When teaching is carried out according to teaching videos, the first steps of most recipes are dish preparation operations, such as cutting scallion, ginger and garlic. Therefore, when a user prepares dishes, the user usually cuts a plurality of shallots, gingers and garlic at one time. In addition, because the teaching videos corresponding to different recipes are different, in order to effectively control the teaching videos and improve user experience, in the application, if the teaching video control device is an intelligent device such as a mobile terminal or an intelligent television, after receiving an instruction of teaching video playing, the display is controlled to play the teaching videos in the corresponding steps. If the teaching video control device is a processor installed on a use tool, after receiving a teaching video playing instruction, the teaching video control device controls the mobile terminal to play the teaching video of the corresponding step.

In the application, the instruction of the teaching video playing can be the teaching video to be checked through the preset operation selection, and after the teaching video to be checked is selected, the corresponding step to be played is selected. Specifically, the instruction for teaching video playing may also be other operations, which is not limited herein. Specifically, the instruction for playing the teaching video may be a selection operation performed on a display or a mobile terminal, or may be a voice message preset to be played and received through a microphone or other devices, and specifically, the instruction for playing the teaching video is not limited herein.

and judging whether the playing of the current step is finished or not according to the corresponding relation between the current step and the playing time length which is stored in advance, and if so, controlling the teaching video to pause playing.

In order to control the display to pause playing after the teaching video corresponding to each step is played, in the application, when the current step is played, the controller determines the playing time length corresponding to the current step according to the corresponding relation between each step and the playing time length which are pre-stored for the teaching video, determines the played time length of the current step, and judges whether the playing of the current step is finished according to the determined played time length of the current step and the playing time length corresponding to the current step. And if the playing of the current step is determined to be finished, controlling the teaching video to pause playing. Specifically, if the teaching video control device is an intelligent device such as a mobile terminal or an intelligent television, the display is controlled to pause playing. If the teaching video control equipment is a processor installed on a use tool, a controller of the teaching video control equipment sends a control instruction to a connected mobile terminal to control the mobile terminal to pause playing.

In order to improve user experience, on the basis of the foregoing embodiments, in the present application, the communicator is further configured to receive a target identifier corresponding to a Radio Frequency Identification (RFID) tag installed on the kitchen knife;

the controller is further configured to:

and determining a target identification corresponding to the RFID label received by the communicator, judging whether the identification corresponding to the current step is the target identification, and if so, judging whether the external sensor is a trigger sensor of the next step of the current step.

Since the kitchen knives used are different when cutting vegetables and when cutting meat, it is further determined whether the kitchen knife used is correct, that is, whether the operation corresponding to the current step is correct. In the present application, the determination may be based on RFID technology. Specifically, different RFID tags can be installed on different kitchen knives, a reader-writer for reading and writing the RFID tags is installed on a chopping board, and when the reader-writer installed on the chopping board reads and writes the RFID tags, the detection range is the chopping range of a user, that is, as long as the user uses a kitchen knife on the chopping board, the RFID tags installed on the kitchen knife can be read and written by the reader-writer. When the kitchen knife is used for cutting things, the kitchen knife approaches the chopping board, and the reader-writer arranged on the chopping board can recognize the RFID tag arranged on the kitchen knife, so that the target identifier corresponding to the read RFID tag is determined, and whether the target identifier is the same as the identifier corresponding to the current step or not is judged.

Specifically, if the teaching video control device is an intelligent device such as a mobile terminal or an intelligent television, a reader-writer installed on a chopping board is used for identifying a target identifier corresponding to a read RFID tag, and sending the identified target identifier to a communicator of the teaching video control device, after receiving the target identifier, the communicator sends the target identifier to a controller, and the controller judges whether the target identifier is the same as an identifier corresponding to the current step. If the teaching video control device is a processor installed on a use tool, after recognizing a target mark, a reader-writer installed on a chopping board sends the recognized target mark to a communicator of the teaching video control device, the communicator sends the target mark to a controller, and the controller judges whether the target mark is the same as a mark corresponding to the current step. If the external sensor is the same as the triggering sensor in the current step, the usage of the kitchen knife is correct, and the step of judging whether the external sensor is the triggering sensor in the next step of the current step is continued.

In addition, in order to ensure that the reader-writer can accurately identify the RFID tag, that is, to ensure the communication between the reader-writer and the RFID tag, in the present application, the chopping board is further provided with an RFID antenna.

In order to improve the user experience, on the basis of the foregoing embodiments, in an embodiment of the present application, the controller is further configured to:

and if the identifier corresponding to the current step is not the target identifier, controlling the playing of the preset first voice information.

Since there may be a case where the kitchen knife is used incorrectly, that is, there may be a case where the received target identifier is not the identifier corresponding to the current step. Therefore, in order to prompt the user and improve the user experience, in the application, if the teaching video control device is an intelligent device such as a mobile terminal or a smart television, the teaching video control device further includes a sound box for playing voice information. And when the received target identifier is not the identifier corresponding to the current step, acquiring corresponding first voice information, and controlling the sound equipment to play the preset first voice information. If the teaching video control device is a processor installed on a use tool, the controller sends an instruction carrying the acquired corresponding first voice information to the mobile terminal when determining that the received target identifier is not the identifier corresponding to the current step, and controls the mobile terminal to play the first voice information.

The first voice message may be "wrong use of the kitchen knife", or "please replace the correct kitchen knife", or other voice messages. The first voice information can be configured when leaving factory, and also can be voice information recorded by the user.

if the external sensor is not the trigger sensor of the next step of the current step, controlling the preset second voice information to be played;

if the preset playing condition is determined not to be met according to the parameter value sent by the external sensor, controlling the preset third voice information to be played;

and if the teaching video is determined to be played completely, controlling the preset fourth voice information to be played.

Since there may be situations where the current step requires salting and the user misplaces sugar or other seasoning, that is, there may be situations where the external sensor is not the trigger sensor for the next step of the current step. Therefore, in order to prompt the user and improve the user experience, in the embodiment of the present application, if the external sensor is not the trigger sensor of the next step of the current step, the corresponding second voice information is determined, and the sound is controlled to play the determined second voice information.

The second voice message may be a simple "error occurs in the current step", or may be a second voice message determined according to a specific situation of the current transmission misoperation, for example, "seasoning placement error".

Since there may be a case that 2g of salt needs to be released and 10g of salt is actually released, that is, it is determined that the preset playing condition is not satisfied according to the parameter value sent by the external sensor. In order to prompt the user and improve user experience, in the application, when the first numerical value is not within the preset first numerical value range, the corresponding third voice information is determined, and the sound is controlled to play the third voice information.

The third voice message may be a simple "error occurs in the current step", or may be a third voice message determined according to a specific situation of the current transmission error operation, for example, "too few seasonings are placed".

Since there may be a case that the currently played teaching video is played completely, in the present application, if it is determined that the currently played teaching video is played completely, the corresponding fourth voice information is acquired, and the sound is controlled to play the acquired fourth voice information.

The fourth voice information may be that the current teaching video is played completely, or the fourth voice information may be determined according to a menu corresponding to the currently played teaching video. Taking the menu corresponding to the current teaching video as tomato-fried eggs as an example for explanation, the fourth voice message may be that the tomato-fried eggs are made. The fourth voice message may be configured when leaving a factory, or may be set by the user.

In this application, if the teaching video control device is an intelligent device such as a mobile terminal or an intelligent television, after the corresponding second voice information, third voice information or fourth voice information is determined, the audio is controlled to play the determined voice information, and if the teaching video control device is a processor installed on a tool, a control instruction carrying the second voice information, the third voice information or the fourth voice information is sent to the mobile terminal to control the mobile terminal to play the corresponding voice information.

In order to accurately control the teaching video, on the basis of the above embodiments, in an embodiment of the present application, the controller is further configured to:

and if the external sensor with the changed parameter value is the trigger sensor of the previous step of the current step, and the parameter value sent by the external sensor is within a preset second value range, controlling to play the teaching video of the previous step of the current step.

Due to the fact that the operation corresponding to the current teaching video is not executed and the deviation exists in the teaching video control device, the teaching video corresponding to the next step is played, and the current operation is not executed. In order to avoid deviation and better meet the user requirement, in the application, the teaching video of the previous step is played by the display through the trigger sensor of the previous step of the current step. The communicator receives a parameter value sent by an external sensor, and sends the received parameter value to the controller, and the controller judges whether the external sensor is the trigger sensor of the previous step of the current step.

In the present application, if the external sensor is the trigger sensor of the previous step of the current step, it is determined whether a parameter value sent by the external sensor is within a preset second parameter value range, and if the parameter value is within the preset second parameter value range, the teaching video of the previous step is controlled to be played.

The trigger sensor in the previous step is introduced by taking an acceleration sensor installed on the kitchen knife as an example, wherein the teaching video corresponding to the previous step can be viewed by rotating the knife handle by a preset angle in a preset direction. Because the acceleration sensor arranged on the kitchen knife can acquire the rotating angles in three directions, when the rotating angles in the preset direction are detected to be within the preset angle range, the fact that the user wants to play the teaching video corresponding to the previous step is indicated. Since it is the prior art to acquire the rotation angle in the preset direction through the acceleration sensor, the details are not described herein.

Fig. 6 is a schematic diagram illustrating parameter value transmission between a teaching video control device and an external sensor according to an embodiment of the present application.

The teaching video control device is a Micro Controller Unit (MCU) microprocessor installed on a chopping board using a tool, and an acceleration sensor, a reader-writer, an RFID antenna, a pressure sensor and an MCU microprocessor are further installed on the chopping board. The acceleration sensor and the teaching video control device can transmit parameter values through a Serial Peripheral Interface (SPI) in the MCU microprocessor, and the reader-writer and the teaching video control device can transmit parameter values through an Asynchronous Receiver/Transmitter (UART) of the MCU microprocessor.

The kitchen knife is provided with the RFID label and the acceleration sensor, and the acceleration sensor arranged on the kitchen knife and the teaching video control device can also transmit parameter values through the SPI when transmitting the parameter values. In general, in order to distinguish whether the received parameter value is transmitted by an acceleration sensor installed on a kitchen knife or an acceleration sensor installed on a cutting board, different sensors transmit the parameter value to the MCU through different interfaces.

Even if two or more external sensors and the teaching video control equipment transmit parameter values through the same interface, when the parameter values are obtained, the controller can access the corresponding external sensors according to a preset time interval, and the external sensors send the parameter values to the teaching video control equipment after receiving access information, so that the received parameter values can be distinguished from the external sensors. For example, the seasoning box is provided with a pressure sensor 1, a pressure sensor 2 and a pressure sensor 3, wherein 3 pressure sensors can transmit parameter values through an I2C bus in the MCU microprocessor, and the pressure sensor arranged on the cutting board can also transmit parameter values through the I2C bus.

In the application, in order to control the teaching video display, the teaching video control device and the mobile terminal can realize data transmission by being connected with the same wifi or being connected through Bluetooth. Specifically, after receiving a playing instruction of the teaching video, the mobile terminal may send a corresponding relationship between each step and a playing duration, a trigger sensor corresponding to a next step of each step, a specific processing mode for a parameter value, and a preset parameter value range, which are stored in the mobile terminal, to the teaching video control device; the mobile terminal may also send the playing instruction of the teaching video to the teaching video control device after receiving the playing instruction of the teaching video, where the playing instruction carries information of the teaching video to be played, and the teaching video control device itself stores the teaching video and pre-stores a corresponding relationship between each step of the teaching video and the playing duration, a trigger sensor of a next step corresponding to each step, a specific processing mode for a parameter value, and a preset parameter value range.

The description is given by taking a menu corresponding to the teaching video as tomato fried eggs as an example. Specifically, the teaching video control device is taken as an example of a processor installed on a use tool.

The first step is: slicing garlic;

and after the teaching video corresponding to the first step is played, controlling the mobile terminal to pause playing the teaching video.

Because when garlic is sliced, the chopping board is vibrated, the garlic cutting times can be obtained according to the parameter values sent by the acceleration sensor arranged on the chopping board, and the garlic cutting times can also be obtained according to the parameter values generated by the accelerometer arranged on the chopping knife, so that in the application, the trigger sensor of the next step of the first step can be the acceleration sensor arranged on the chopping board, and can also be the acceleration sensor arranged on the chopping knife.

And because under normal conditions, after the vegetables are cut, the kitchen knife is placed flat, the cut vegetables are placed in the container for placing the vegetables through the kitchen knife, and the situation that the lower hand is loosened momentarily during the vegetables cutting and the kitchen knife is put down can also exist, therefore, in the application, if the vegetable cutting times are determined by the parameter values sent by the acceleration sensor arranged on the kitchen knife or the acceleration sensor arranged on the chopping board, errors are easy to cause, and the noise of the vegetable cutting times can be removed through the angle obtained by the acceleration sensor arranged in the kitchen knife. When the controller determines the times of the parameter value change through the acceleration sensor arranged on the chopping board, the filtering can be carried out by the following formula.

Wherein, the times is the garlic cutting times detected by the current controller, and the times is the garlic cutting times detected by the current controller ₀ The last time the controller detects the garlic cutting times, the roll is the rolling angle of the rotation of the kitchen knife detected by the controller, and the threshold is the maximum value of the roll angle during vegetable cutting.

And when the detection times are within the preset time range, determining that the preset playing conditions are met, and controlling the mobile terminal to continuously play the teaching video corresponding to the second step.

As shown in fig. 7, the first step is to slice garlic, and after the teaching video corresponding to the first step is completely played, the content displayed by the mobile terminal when the teaching video is paused is an image obtained when garlic is cut.

The second step is: cutting shallot;

and after the teaching video corresponding to the second step is played, controlling the mobile terminal to pause playing the teaching video.

The determination method of the second step is the same as that of the first step, and is not described herein again.

As can be seen from fig. 8, the second step is to cut the shallot, and after the teaching video corresponding to the second step is played, the content displayed by the mobile terminal when the teaching video is paused is the image when the shallot is cut.

The third step is: cutting tomatoes;

and after the teaching video corresponding to the third step is played, controlling the mobile terminal to pause playing the teaching video.

The fourth step: beating eggs into a bowl;

and after the teaching video corresponding to the fourth step is played, controlling the mobile terminal to pause playing the teaching video.

Because the pressure sensor installed on the chopping board can detect the change of pressure when eggs are beaten into the bowl. Therefore, in the present application, the next step of the fourth step, that is, the trigger sensor of the fifth step, may be a pressure sensor installed on the cutting board, and when receiving a parameter value sent by an external sensor, it may be determined first whether the external sensor is a corresponding pressure sensor, and if so, the subsequent determination is continued.

Generally, if a user presses eggs into the bowl, the pressure of the pressure sensors arranged on the chopping board is sequentially increased, and if the parameter value sent by the pressure sensor is within a preset parameter range, the preset playing condition is determined to be met, and the mobile terminal is controlled to play the teaching video in the fifth step.

Fig. 10 is a content displayed by the mobile terminal when the teaching video is paused after the teaching video corresponding to the fourth step of frying eggs with tomatoes is played.

As shown in fig. 10, the fourth step is to punch eggs into the bowl, and after the teaching video corresponding to the fourth step is played, the content displayed by the mobile terminal when the teaching video is paused is an image formed by punching eggs into the bowl.

Fifthly, breaking up the eggs;

and after the teaching video corresponding to the fifth step is played, controlling the mobile terminal to pause playing the teaching video.

At this moment, an acceleration sensor installed on the chopping board can detect the vibration state of the chopping board, so that a trigger sensor in the sixth step is the acceleration sensor installed on the chopping board, if a parameter value sent by the acceleration sensor located on the chopping board is received, subsequent judgment is continued, when the parameter value sent by the acceleration sensor is determined to be a target curve when the parameter value is changed according to other parameter values received within a preset time length before the parameter value is received, if the target curve is similar to a preset curve, the user is considered to be stirring eggs, the preset playing condition is determined to be met, and the mobile terminal is controlled to play the teaching video in the sixth step.

Sixthly, adding hot oil into the pot, pouring eggs into the pot, and frying the eggs;

When eggs are poured into the pot, the pressure sensor arranged on the chopping board can change, so that the trigger sensor in the seventh step is the pressure sensor on the chopping board, if the external sensor receiving the sent parameter value is the pressure sensor on the chopping board, whether the parameter value sent by the external sensor is within the preset numerical range is judged, and if yes, the subsequent operation is continued. Since the eggs are required to be fried after being poured into the pan, in the application, after the parameter values sent by the pressure sensors are determined to be within the preset numerical range, the preset playing conditions are determined to be met after the set time length, and the mobile terminal is controlled to play the teaching video corresponding to the seventh step.

Fig. 11 is a content displayed by the mobile terminal when the teaching video is paused after the teaching video corresponding to the sixth step of frying eggs with tomatoes is played.

As shown in fig. 11, in the sixth step, hot oil is added into the pan, eggs are poured into the pan, the pan is fried, and after the teaching video corresponding to the sixth step is played, the content displayed by the mobile terminal when the teaching video is paused is an image of the fried eggs.

and after the teaching video corresponding to the seventh step is played, controlling the mobile terminal to pause playing the teaching video.

When eggs are placed in the dish to be contained, the pressure sensor arranged on the chopping board changes, so that the trigger sensor in the eighth step is the pressure sensor arranged on the chopping board, if the external sensor receiving the sent parameter value is the pressure sensor arranged on the chopping board, whether the parameter value sent by the pressure sensor is within a preset numerical range is judged, if yes, a preset playing condition is determined to be met, and the display is controlled to play the teaching video corresponding to the eighth step.

Fig. 12 is a content displayed by the mobile terminal when the teaching video is paused after the teaching video corresponding to the seventh step of frying eggs with tomatoes is played.

As can be seen from fig. 12, in the seventh step, the fried eggs are put into the tray to be filled, and after the teaching video corresponding to the seventh step is played, the content displayed by the mobile terminal when the teaching video is paused is an image in which the fried eggs are put into the tray to be filled.

Eighthly, oil is left at the bottom of the pan, and garlic slices are poured into the pan and fried quickly;

and after the teaching video corresponding to the eighth step is played, controlling the mobile terminal to pause the playing of the teaching video.

The judgment method in the eighth step is the same as that in the sixth step, and is not described herein again.

Eleventh, adding salt, and quickly stir-frying for flavoring;

and after the teaching video corresponding to the eleventh step is played, controlling the mobile terminal to pause playing the teaching video.

Since the pressure sensor located in the seasoning box under the salt box will detect the change in pressure when the salt is added. Therefore, the trigger sensor in the twelfth step may be a pressure sensor installed below the salt box, and when receiving a parameter value sent by an external sensor, the trigger sensor may first determine whether the external sensor is a corresponding pressure sensor, if so, determine whether the parameter value sent by the pressure sensor is within a preset value range, if so, and after a set duration, determine that a playing condition is met, and control the mobile terminal to play the twelfth step.
