具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述本申请实施例的电磁加热设备及噪音抑制方法、加热控制***、存储介质。
图1是本申请一个实施例的电磁加热设备的电磁噪音抑制方法的流程图。
如图1所示，电磁加热设备的电磁噪音抑制方法包括以下步骤：
S11，在确定电磁加热设备的相邻两个加热模块先后进行工作时，获取后启动加热模块的开始工作频率。
需要说明的是，由于电磁加热设备的加热模块的工作频率普遍较高，因此可以通过控制驱动模块输出的驱动信号的频率来控制加热模块的工作频率。
作为一个示例，可事先获取电磁加热设备上所有加热模块的开始工作频率，进而获取与该开始工作频率对应的驱动信号的频率，并可将该驱动信号的频率存储在电磁加热设备的存储器内。进一步地，若确定相邻两个加热模块先后进行工作，则可从存储设备内获取后启动加热模块所需要的驱动信号的频率。
上述的所有加热模块所需要的驱动信号的频率也可存储在云端服务器内，若确定相邻两个加热模块先后进行工作，则可从云端服务器获取后启动加热模块所需要的驱动信号的频率。
S12，根据后启动加热模块的开始工作频率对先启动加热模块的工作频率进行调节，以便在后启动加热模块开始工作时相邻两个加热模块采用相同工作频率同步进行工作。
作为一个示例，如图2所示，交流电源10输出交流信号。过零检测模块60接收交流电源10输出的交流信号，并对该交流信号进行处理得到零伏检测信号，进而将该零伏检测信号传输给控制模块30。控制模块30可通过驱动模块控制功率模块输出线圈所需要的谐波电压波形，从而实现控制模块对加热模块的控制。
其中，上述控制模块30控制加热模块的方法可以为：控制先启动加热模块的工作频率降低至后启动加热模块的开始工作频率时，控制后启动加热模块以同样的工作频率同步开始工作。
在本实施例中，如图3所示，在后启动模块开始工作之前，控制模块30控制驱动模块40输出驱动信号，该驱动信号的频率为线圈90正常工作需要的频率，功率模块70根据该驱动信号输出能使线圈90正常工作的A谐振电压波形。控制模块30控制驱动模块50不输出驱动信号。
在后启动模块开始工作时，控制模块30控制驱动模块50输出驱动信号，该驱动信号的频率为线圈100启动加热所需要的频率，进而功率模块80根据接收到的驱动信号输出能使线圈100启动加热的B谐振电压波形。控制模块30控制驱动模块40将输出的驱动信号的频率提升至与驱动模块50输出的驱动信号的频率相同。
上述控制模块30控制加热模块的方法还可为：控制先启动加热模块停止工作，并在预设时间后，根据后启动加热模块的开始工作频率控制先启动加热模块和后启动加热模块同 步开始工作。
在本实施例中，如图4所示，在后启动模块开始工作第一预设时间之前，控制模块30控制驱动模块40输出驱动信号，该驱动信号的频率为线圈90正常工作需要的频率，功率模块70根据该驱动信号输出能使线圈90正常工作的A谐振电压波形。控制模块30控制驱动模块50不输出驱动信号。其中，上述第一预设时间可以由用户自行设置，也可以为设备默认的预设时间。
在后启动模块开始工作前第一预设时间之内，控制模块30控制驱动模块40与控制模块50均不输出驱动信号。即，在后启动模块开始工作前第一预设时间内，控制先启动的线圈90停止加热。
在后启动模块开始工作时，控制模块30控制驱动模块50输出驱动信号，该驱动信号的频率为线圈100启动加热所需要的频率，进而功率模块80根据接收到的驱动信号输出能使线圈100启动加热的B谐振电压波形。控制模块30控制驱动模块40输出驱动信号，该驱动信号的频率与驱动模块50输出的驱动的信号频率相同。
由此，可以实现在后启动的线圈100开始启动时，将驱动模块40输出的驱动信号的频率调整至与驱动模块50输出的驱动信号的频率相同。
在相邻两个加热模块采用相同工作频率同步进行工作后，相邻两个加热模块的工作频率变化趋势保持一致。即，随着线圈100进行启动加热过程，线圈100所需要的驱动信号的频率逐渐降低，驱动模块50输出能满足线圈100的需求的驱动信号，功率模块80根据接收到的驱动信号输出对应的B谐振电压波形，使得线圈100进行启动加热过程；同时，控制模块30控制驱动模块40输出驱动信号，该驱动信号的频率与驱动模块50输出的驱动信号的频率相同。控制模块30与控制模块40输出相同频率的驱动信号直至线圈100完成启动加热过程。
由此，可以实现在后启动的线圈100启动的过程中，驱动信号40输出的驱动信号的频率变化与驱动模块50输出的驱动信号的频率变换保持同步。
在相邻两个加热模块同步进行工作的过程中，相邻两个加热模块的PWM信号的占空比在0-50％之间独自可调。即，虽然驱动模块40与驱动模块50输出的驱动信号的频率一致，但驱动模块40与驱动模块50输出的驱动信号的占空比可以不相同。
需要说明的是，本申请实施例的电磁加热设备的电磁噪音抑制方法，也可以对多个相邻的加热模块进行控制。例如，若有3个相邻的加热模块A、B、C，加热模块A最先开始工作，加热模块C最后开始工作。则可在加热模块B启动加热的过程中控制加热模块A保持与加热模块B同步；在加热模块C启动加热的过程中控制加热模块A、加热模块B保持与加热模块C同步。
综上，本申请实施例的电磁加热设备的电磁噪音抑制方法，可以实现在后启动的加热模块开始工作时，将先启动的相邻加热模块的工作频率调整至与后启动的加热模块的工作频率相同，从而令先启动的加热模块与后启动的加热模块的线圈磁场方向相同，实现消除电磁噪音。进而在后启动的加热模块的启动过程中，先启动的相邻加热模块与其保持线圈磁场方向同步，从而实现在后启动的加热模块的启动过程中无电磁噪音。
进一步地，本申请提出一种计算机可读存储介质。

进一步地，本申请提出一种电磁加热设备。
