In the present application, when the control circuit 13 acquires multiple signals, it can also determine the characteristics of the signals, and the characteristics of the signals can be used to indicate the types of functional signals in the multiple signals. Therefore, the control circuit 13 can determine the type of the function signal received from the cookware 20 based on the characteristics of the signal, so that the control circuit 13 can know the type of each signal, which is helpful for the control circuit 13 to perform the corresponding operation accurately, avoiding misoperation occurred.

In the signal processing method provided by the present application, when the heating platform is matched with the cookware, based on the electrical contact between one or more first contact groups in the heating platform and the corresponding second contact group in the cookware, the heating platform in the heating platform is in electrical contact. The control circuit may acquire a plurality of signals, wherein the plurality of signals include at least one functional signal. Since the characteristics of the signals can be used to indicate the type of functional signal among the plurality of signals, the control circuit can determine the type of functional signal received from the cookware based on the characteristics of the signals. Therefore, by accurately knowing the type of each signal, the heating platform can accurately obtain the properties of the cookware, which is beneficial to the heating platform to understand the current state of the cookware in an all-round way, so as to make timely decisions corresponding to the type of the signal.

In the following, the specific implementation process of determining the type of the function signal received from the cooking utensil 20 by the control circuit 103 based on the characteristics of the signal in S102 is illustrated by way of example in combination with two feasible implementation manners.

In a feasible implementation manner, the control circuit 13 may store the correspondence between the number of signals and the types of signals in advance. Wherein, the corresponding relationship can adopt various storage methods such as table, sequence and matrix, which are not limited in this application, and the corresponding relationship can be set according to the actual number of signals transmitted on any one pot 20, or can be set according to the heating Among the types of cookware 20 that the platform 10 can match, the number of signals transmitted by different types of cookware 20 can be set, and can also be set according to the combination of the first two methods, which is not limited in this application.

Therefore, the control circuit 13 can determine the number of signals received from the cookware 20 based on the characteristics of the signals, so that the control circuit 13 can determine the number of signals received from the cookware 20 according to the corresponding relationship between the number of signals and the types of signals. The type of function signal.

For example, assuming that the number of signals is 1, the types of signals include temperature signals; the number of signals is 2, and the types of signals include temperature signals and pressure signals. Therefore, when the number of signals received by the control circuit 13 is 2, the control circuit 13 can determine that the types of function signals received from the cookware 20 include temperature signals and pressure signals, so that the control circuit 13 can compare the temperature signals and the pressure signals respectively. The pressure signal operates accordingly.

The number of signals may be the total number of multiple signals, or may be the total number of signals received from the first contact group 12 located on one side of the heating platform body 11 , which is not limited in this application.

In addition, when the heating platform 10 can be matched with multiple types of cookware 20, the control circuit 13 may also store the correspondence between the number of signals and the types of cookware in advance. Wherein, the corresponding relationship may adopt various storage modes such as a table, a sequence, and a matrix, which are not limited in this application. Therefore, the control circuit 13 can determine the number of signals received from the cookware 20 based on the characteristics of the signals, so that the control circuit 13 can determine the type of the cookware 20 according to the corresponding relationship between the number of signals and the type of the cookware. , not only can distinguish the type of cookware 20 that can be matched with the heating platform 10 to realize the precise control of the heating platform 10, but also can distinguish any cookware 20 that can be placed on the heating platform 10 in a variety of matching positions. Coupling states such as forward or reverse. The matching position is used to indicate the coupling state of the signal transmission between the cookware 20 and the heating platform 10 .

For example, with reference to FIG. 3 , for the convenience of description, in FIG. 3 , the number of the first contact group 12 in the heating platform 10 is shown as two, and the number of the first contact group 121 in each first contact group 12 is shown as Three are shown for illustration, and FIG. 3 includes two types of pots 20 , namely, a stew pot A and a soup pot B. One side of each pot 20 is provided with a second contact group 22 , the second contact The group 22 includes three second contacts 221 as an example for illustration.

Assume the correspondence between the number of signals and the type of pot: the number of signals is 1, and the type of pot 20 is stew pot A; the number of signals is 2, and the type of pot 20 is soup pot B. As shown in FIG. 3 , when the cookware 20 is placed on the heating platform 10, when the number of signals received by the control circuit 13 is 1, the control circuit 13 can determine the type of the cookware placed on the heating platform 10 as: Stew pot A, so that the control circuit 13 can operate accordingly. When the number of signals received by the control circuit 13 is 2, the control circuit 13 can determine that the type of pot placed on the heating platform 10 is a soup pot B, so that the control circuit 13 can perform corresponding operations.

Based on the above description, when the heating platform 10 includes a first contact group 12 , the control circuit 13 can accurately determine the type of function signal transmitted by the second contact group 22 matched with the first contact group 12 , so that the control circuit 13 can accurately determine the type of the function signal transmitted by the plurality of second contact groups 22 in the cookware 20 by changing the matching position (ie, the coupling state of the cookware 20 ). In this way, it is convenient to select different second contact groups 22 in the cookware 20 to match the first contact group 12 on the heating platform 10 according to actual needs, so that the control circuit 13 can obtain the desired functions. signal, so as to make the control circuit 13 know the properties and characteristics of the cookware 20 in time, so as to facilitate the control circuit 13 to make corresponding adjustments.

When the heating platform 10 includes two or more first contact groups 12, the control circuit 13 can determine the number of signals received from the plurality of first contact groups 12 based on the characteristics of the signals, so that the control circuit 13 can control the The circuit 13 determines the type of the function signal transmitted by the second contact group 22 matched with each first contact group 12, so that the control circuit 13 can accurately determine the signal transmitted by the plurality of second contact groups 22 in the cookware 20. Type of function signal. In this way, it is convenient to select different second contact groups 22 in the cookware 20 to match with the plurality of first contact groups 12 on the heating platform 10 according to actual needs, so that the control circuit 13 can obtain the desired functions. signal, so as to make the control circuit 13 know the properties and characteristics of the cookware 20 in time, so as to facilitate the control circuit 13 to make corresponding adjustments.

Optionally, when a plurality of first contact groups 12 are located on both sides of the heating platform body 11 , the control circuit 13 may determine the number of signals received from the first contact groups 12 located on one side of the heating platform body 11 . A number, and a second number of signals received from the first contact group 12 located on the other side of the heating platform body 11 . Since the control circuit 13 stores the correspondence between the quantity and the type of the signal in advance, when the first quantity is different from the second quantity, the control circuit 13 can compare the correspondence between the quantity and the type of the signal to determine The type of each function signal obtained from the corresponding first contact group on any side of the heating platform body 11 is obtained, so as to determine the type of the function signal received from the cookware.

It should be noted that, on the basis of the foregoing content, the control circuit 13 may also store in advance the corresponding relationship between the number and the arrangement order of the signals. Wherein, the corresponding relationship may adopt various storage modes such as a table, a sequence, and a matrix, which are not limited in this application. Therefore, the control circuit 13 compares the corresponding relationship between the number and the arrangement order of the signals, and can determine the positional relationship of each functional signal.

For example, assume the correspondence between the number of signals and the arrangement order of the signals: the number of signals is 2, from any side of the heating platform body 11, the arrangement order of the signals is the temperature signal and the pressure signal; the number of signals is 2, From this side of the heating platform body 11, the arrangement order of the signals is a temperature signal, a pressure signal and a water level signal. Therefore, when the number of signals received by the control circuit 13 is 2, the control circuit 13 can determine that the order of the signals is the temperature signal and the pressure signal, so that the control circuit 13 can perform corresponding operations.

In addition, the control circuit 13 may also store in advance the corresponding relationship between the number and the coupling state of the cookware. Wherein, the corresponding relationship may adopt various storage modes such as a table, a sequence, and a matrix, which are not limited in this application. Therefore, when the first number is different from the second number, the control circuit 13 can determine that the heating platform 10 and the cookware 20 are successfully coupled on the front or the reverse side by comparing the corresponding relationship between the number and the coupling state of the cookware. It can also prompt the user that the heating platform 10 and the cookware 20 are successfully coupled on the front or on the reverse side, for example, the display screen on the heating platform body 11 is used to display the corresponding text to the user, or the lights of different colors on the heating platform body 11 are used to display to the user. For corresponding prompts, etc., the foregoing two processes may also be performed, which is not limited in this application.

In this way, when the user places the cookware 20 on the heating platform 10, the front or back of the cookware 20 can be successfully coupled to the heating platform 10 without considering the front or the back of the cookware 20, which is beneficial to simplification and convenience for the user. operation, improve the user's sense of use.

For example, with reference to FIG. 4 , for the convenience of description, in FIG. 4 , the number of the first contact groups 12 in the heating platform 10 is shown as two, and the number of the first contacts 121 in each first contact group 12 is shown as Three are shown for illustration, and in FIG. 4, the cookware 20 is provided with a second contact group 22 on both sides of the cookware 20, wherein one second contact group 22 includes three second contacts 221 for use in To transmit one kind of function signal, another second contact group 22 includes four second contacts 221 for transmitting two kinds of function signals as an example for illustration.

Assume the correspondence between the number of signals and the coupling state of the cookware: the number of signals is 1, and the coupling state of the cookware is the front; the number of signals is 2, and the coupling state of the cookware is the reverse. As shown in FIG. 4 , when the number of functional signals received by the control circuit 13 is 1, the control circuit 13 can determine that the cookware 20 is placed on the heating platform 10, that is, the heating platform 10 and the cookware 20 are successfully coupled on the front. So that the control circuit 13 can perform corresponding operations. When the number of function signals received by the control circuit 13 is 2, the control circuit 13 can determine that the cookware 20 is placed on the heating platform 10 upside down, that is, the heating platform 10 is successfully coupled to the reverse side of the cookware 20, so that the control circuit 13 can respond accordingly operation.

In another feasible implementation manner, the control circuit 13 may determine the types of the multiple signals based on the multiple received signals. When the control circuit 13 determines that the multiple signals include one or more prompt signals and one or more function signals, since the prompt signal can be used to indicate the successful coupling between the heating platform 10 and the cookware 20, the control circuit 13 can determine the characteristics of the prompt signal such as quantity, location or serial number, so that the control circuit 13 can determine the type of the function signal in the multiple signals, that is, determine the type of the function signal received from the cookware 20 .

For example, it is assumed that the number of prompt signals is 1, and the types of functional signals include temperature signals; the number of prompt signals is 2, and the types of functional signals include temperature signals and pressure signals. Therefore, when the number of prompt signals received by the control circuit 13 is 2, the control circuit 13 can determine that the types of the function signals received from the cookware 20 include a temperature signal and a pressure signal, so that the control circuit 13 can compare the temperature signal with the temperature signal respectively. and the corresponding operation of the pressure signal.

For another example, suppose the prompt signal is located on the A side of the heating platform body 11, and the type of functional signal includes temperature signal; the prompt signal is located on the B side of the heating platform body 11, and the type of functional signal includes temperature signal and pressure signal. Therefore, when the prompt signal received by the control circuit 13 is located on the A side of the heating platform body 11, the control circuit 13 can determine that the type of the function signal received from the cookware 20 includes the temperature signal, so that the control circuit 13 can communicate with the temperature signal. corresponding action.

Optionally, the control circuit 13 can determine the position of the first contact 121 in the first contact group 12 corresponding to the prompt signal, so that the control circuit 13 can determine the function signal corresponding to the first contact 121 in the remaining positions based on the position. type.

Alternatively, the multiplexing contact 221A can transmit signal 1, signal 2, and signal 3. Among them, signal 1, signal 2 and signal 3 are different types of signals. In addition, for any two multiplexing contacts 221A, the signals that can be received by the two multiplexing contacts 221A may be of the same type, or may be of different types, which is not limited in this application.

The sets 22 are matched so that the cookware 20 can transmit various types of signals to the heating platform 10 through the second contact set 22 so that the heating platform 10 and the cookware 20 are successfully coupled, thereby reducing the number of conductive contacts.

Wherein, the present application does not limit the number of the second contacts 221 in the second contact group 22 . Optionally, the number of the second contacts 221 in each second contact group 22 may be the same or different.
