[0025] As mentioned in the background, the prior art cooking utensils lack detection of detection device failure. To solve the above problems, in a typical embodiment of the present application, a detection method, device, computer readable storage medium, processor and cooking system for detecting the state of the detection device are provided.

[0026] According to an embodiment of the present application, a detection method for detecting the state of the detection device is provided.

[0027] Figure 1 is a flowchart of the detection method for detecting the state of the detection device according to an embodiment of the present application. As shown in Figure 1 , the detection method comprises the following steps:

[0028] Step S101, obtaining cover state information detected by the detection device, the cover state information being used to at least represent whether the cover is opened or not;

[0029] In the above steps, the detection device can be a sensor. If the sensor detects a signal that the cover switch is closed within a certain time (ms level), it is confirmed that the cover is not opened. If the sensor detects a signal that the cover switch is disconnected within a certain time (ms level), it is confirmed that the cover is opened. Those skilled in the art can also select any detection device that can detect the cover state information of the cooking utensil. This step can quickly obtain the state of the cover of the cooking utensil as opened or not opened.

[0030] Step S102, determining whether the detection device is failed according to the cover state information and predetermined information, wherein the predetermined information comprises at least one of the following: information representing the function mode of the cooking utensil, voltage for controlling the detection device, voltage output by the detection device, when the detection device is failed, the detection device cannot correctly detect the cover state information.

[0031] In the above steps, the operation habit of the user, i.e., the information representing the function mode of the cooking utensil, the running state of the cooking utensil, i.e., the voltage of the control detection device and the voltage output by the detection device, and the situation that will occur when the user uses the cooking utensil are preset in advance, and in combination with the predetermined information, the detection of the failure of the detection device is realized in a software manner without increasing the hardware cost.

[0032] In the embodiment of the present application, the state of the detection device of the cooking utensil is detected, the cover information detected by the detection device, the information representing the function mode of the cooking utensil, the voltage of the control detection device and the voltage output by the detection device are used to determine whether the detection device is failed, so that the detection device can be detected in time when it is failed, and the technical problem that the detection device of the cooking utensil is not detected in the prior art is solved, and the stable work of the detection device of the cooking utensil is ensured.

[0033] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0034] On the basis of the above steps S101 to S102, the above step S102 is further refined, and the step specifically includes: in the case that the cover state information represents that the cover is opened, determining whether the detection device is failed according to at least one of the information representing the function mode of the cooking utensil, the voltage of the control detection device and the voltage output by the detection device. In the above steps, based on the use habit of the user, the cover state information can be divided into opened and unopened. In the case that the cover is opened, whether the detection device is failed can be quickly determined according to the above steps.

[0035] On the basis of the step S1021, the step S1021 is further refined. In the case that the cover state information represents that the cover is safely opened, according to the information representing the function mode of the cooking appliance, it is determined whether the detection device is invalid. The step specifically includes: in the case that the information representing the function mode of the cooking appliance represents the open-cooking mode, it is determined that the detection device is not invalid; and in the case that the information representing the function mode of the cooking appliance represents the non-open-cooking mode, it is determined that the detection device is invalid. In the above steps, the cover state information representing that the cover is safely opened can be the open-cooking in the standby state, the function selection state, the taste selection state, and the reservation time setting state of the cooking appliance. Because in the above cases, the open-cooking has no safety hazard for the user. In the case that the cover state information represents that the cover is safely opened, only the cooking appliance is in the open-cooking mode. Therefore, whether the detection device is invalid can be determined according to whether the information representing the function mode of the cooking appliance represents the open-cooking mode. The above method can quickly determine whether the detection device is invalid in the case that the cover state information represents that the cover is safely opened.

[0036] On the basis of the step S1021, the step S1021 is further refined. In the case that the cover state information represents that the cover is safely opened, according to the information representing the function mode of the cooking appliance, it is determined whether the detection device is invalid. The step specifically includes: in the case that the information representing the function mode of the cooking appliance represents the open-cooking mode, it is determined that the detection device is not invalid; and in the case that the information representing the function mode of the cooking appliance represents the non-open-cooking mode, it is determined that the detection device is invalid. In the above steps, the cover state information representing that the cover is safely opened can be the open-cooking in the standby state, the function selection state, the taste selection state, and the reservation time setting state of the cooking appliance. Because in the above cases, the open-cooking has no safety hazard for the user. In the case that the cover state information represents that the cover is safely opened, only the cooking appliance is in the open-cooking mode. Therefore, whether the detection device is invalid can be determined according to whether the information representing the function mode of the cooking appliance represents the open-cooking mode. The above method can quickly determine whether the detection device is invalid in the case that the cover state information represents that the cover is safely opened.

[0037] On the basis of the above steps S101 to S102, the above step S102 is further refined, and the step specifically comprises: in the case that the cover state information represents that the cover is not opened, determining whether the detection device is invalid according to the voltage of the control detection device and the voltage output by the detection device. In the above step, based on the use habit of the user, the cover state information can be divided into opened and not opened, and in the case that the cover is not opened, the detection device can be quickly determined to be invalid according to the above step.

[0038] On the basis of the above step S1022, the step S1022 is further refined, and the step specifically comprises: in the case that the voltage of the control detection device is the same as the voltage output by the detection device, determining that the detection device is invalid; and in the case that the voltage of the control detection device is different from the voltage output by the detection device, determining that the detection device is not invalid. In the above step, whether the detection device is invalid can be determined according to the change of the voltage of the control detection device. The cover opening switch of the cooking utensil can be normally closed, and the voltage output by the detection device is high level, so the level of the initialization of the control detection device can be set to low level. When powered on, the voltage of the control detection device is read and stored, and then the level of the voltage of the control detection device after power-on is read and stored, and whether the level signals read twice are consistent is compared, if not, it is judged that the detection device is not invalid, and if consistent, it is judged that the detection device is invalid. The above method can quickly determine whether the detection device is invalid in the case that the cover state information represents that the cover is safely opened.

[0039] In another specific embodiment of the present application, the overall flow of the detection method of the above detection device state is as follows: Figure 2As shown. First, the detection parameters of the detection device are initialized, the duration of the effective level of the detection sensor is set, and the controller can effectively identify the high and low levels. The detection device judges whether the cooking utensil is open or not, and the cover state of the cooking utensil can be non-safety opening, safety opening and non-opening. In the non-safety opening state, it is judged whether the voltage of the detection device in the case of the cover not being opened is the same as the voltage output by the detection device in the case of the cover not being opened, and whether the voltage of the detection device in the case of the cover being non-safety opened is the same as the voltage output by the detection device in the case of the cover being non-safety opened. When both are the same, it is determined that the detection device is not failed, and there is a difference between the two, then it is determined that the detection device is failed. In the safety opening state, the cooking utensil is in the open cooking mode, so if the cooking utensil is in the open cooking mode, it is determined that the detection device is not failed. If the cooking utensil is in the non-open cooking mode, it is determined that the detection device is failed. In the non-opening state of the cooking utensil, it is judged whether the voltage of the detection device is the same as the voltage output by the detection device. If the voltage of the detection device is the same as the voltage output by the detection device, it is determined that the detection device is failed. If the voltage of the detection device is different from the voltage output by the detection device, it is determined that the detection device is not failed.

[0040] The embodiment of the present application also provides a detection device for detecting the state of the detection device. It should be noted that the detection device for detecting the state of the detection device provided in the embodiment of the present application can be used to execute the detection method for detecting the state of the detection device provided in the embodiment of the present application. The detection device for detecting the state of the detection device provided in the embodiment of the present application is introduced as follows.

[0041] Figure 3 Fig. 1 is a structural schematic diagram of the detection device for detecting the state of the detection device according to the embodiment of the present application. As shown in the figure, the detection device comprises: Figure 3

[0042] The acquisition unit 10 is configured to acquire the cover state information detected by the detection device, and the cover state information is used to at least represent whether the cover is opened or not.

[0043] In the above device, the detection device can be a sensor. If the sensor detects a signal that the cover switch is closed within a certain time (ms level), it is confirmed that the cover is not opened. If the sensor detects a signal that the cover switch is disconnected within a certain time (ms level), it is confirmed that the cover is opened. The skilled in the art can also select any detection device that can detect the cover state information of the cooking utensil. The device can quickly acquire the state of the cover of the cooking utensil being opened or not.

[0044] ​The determining unit 20 is configured to determine whether the detection device is invalid according to the cover state information and predetermined information, wherein the predetermined information comprises at least one of information representing a function mode of the cooking appliance, a voltage for controlling the detection device, and a voltage output by the detection device, and the detection device cannot correctly detect the cover state information when the detection device is invalid.

[0045] In the above device, the information representing the function mode of the cooking appliance, the operating state of the cooking appliance, the voltage for controlling the detection device, and the voltage output by the detection device are used to determine the situation that will occur when the user uses the cooking appliance, and the predetermined information is used to comprehensively detect whether the detection device is invalid by a software manner without increasing hardware cost.

[0046] In the embodiment of the present application, the detection device is used to detect the state of the cooking appliance, and the cover information detected by the detection device, the information representing the function mode of the cooking appliance, the voltage for controlling the detection device, and the voltage output by the detection device are used to determine whether the detection device is invalid, so that the invalid detection device can be detected in time, and the technical problem that the cooking appliance lacks detection of the invalid detection device in the prior art is solved, and the detection device of the cooking appliance can work stably.

[0047] On the basis of the above obtaining unit and determining unit, the determining unit is further refined, and specifically comprises: a first determining module configured to determine whether the detection device is invalid according to at least one of the information representing the function mode of the cooking appliance, the voltage for controlling the detection device, and the voltage output by the detection device when the cover state information represents that the cover is opened. In the above step, the cover state information can be divided into opened and unopened based on the use habit of the user. When the cover is opened, whether the detection device is invalid can be quickly determined according to the above step.

[0048] On the basis of the first determination module, the first determination module is further refined. In the case that the cover state information represents that the cover is safely opened, whether the detection device is invalid is determined according to information representing a function mode of the cooking appliance. Specifically, the first determination submodule is configured to determine that the detection device is not invalid in the case that the information representing the function mode of the cooking appliance represents an open-cooking mode. The second determination submodule is configured to determine that the detection device is invalid in the case that the information representing the function mode of the cooking appliance represents a non-open-cooking mode. In the above steps, the cover state information representing that the cover is safely opened can be that the cover is opened in a standby state, a function selection state, a taste selection state, or a reservation time setting state of the cooking appliance. In the above cases, opening the cover does not pose a safety hazard to the user. In the case that the cover state information represents that the cover is safely opened, only the cooking appliance is in the open-cooking mode. Therefore, whether the detection device is invalid can be determined according to whether the information representing the function mode of the cooking appliance represents the open-cooking mode. The above device can quickly determine whether the detection device is invalid in the case that the cover state information represents that the cover is safely opened.

[0049] On the basis of the first determination module, the first determination module is further refined. In the case that the cover state information represents that the cover is safely opened, whether the detection device is invalid is determined according to information representing a function mode of the cooking appliance. Specifically, the first determination submodule is configured to determine that the detection device is not invalid in the case that the information representing the function mode of the cooking appliance represents an open-cooking mode. The second determination submodule is configured to determine that the detection device is invalid in the case that the information representing the function mode of the cooking appliance represents a non-open-cooking mode. In the above steps, the cover state information representing that the cover is safely opened can be that the cover is opened in a standby state, a function selection state, a taste selection state, or a reservation time setting state of the cooking appliance. In the above cases, opening the cover does not pose a safety hazard to the user. In the case that the cover state information represents that the cover is safely opened, only the cooking appliance is in the open-cooking mode. Therefore, whether the detection device is invalid can be determined according to whether the information representing the function mode of the cooking appliance represents the open-cooking mode. The above device can quickly determine whether the detection device is invalid in the case that the cover state information represents that the cover is safely opened.

[0050] On the basis of the acquisition unit and the determination unit, the determination unit is further refined, and specifically includes: a second determination module, configured to, in a case where the cover state information represents that the cover is not opened, determine whether the detection device is invalid according to a voltage for controlling the detection device and a voltage output by the detection device. In the step, based on the use habit of the user, the cover state information can be divided into opened and not opened, and in the case where the cover is not opened, the detection device can be quickly determined to be invalid according to the step.

[0051] On the basis of the second determination module, the second determination module is further refined, and specifically includes: a fifth determination submodule, configured to, in a case where the voltage for controlling the detection device is the same as the voltage output by the detection device, determine that the detection device is invalid; and a sixth determination submodule, configured to, in a case where the voltage for controlling the detection device is different from the voltage output by the detection device, determine that the detection device is not invalid. In the step, whether the detection device is invalid can be determined according to the voltage change for controlling the detection device. The cover opening switch of the cooking utensil can be normally closed, the voltage output by the detection device is a high level, and therefore the level for controlling the initialization of the detection device can be set to a low level. When powered on, the voltage for controlling the detection device is read and stored, and then the level of the voltage for controlling the detection device after being powered on is read and stored, and whether the level signals read twice are consistent is compared, if not, it is determined that the detection device is not invalid, and if yes, it is determined that the detection device is invalid.
