Problems solved by technology

[0002] In related technologies, household appliances (such as soybean milk machines, washing machines, televisions, and refrigerators, etc.) usually experience abnormal power outages due to failures in power frequency lines. In order to ensure that the sensor modules of household appliances can continue to be For sampling processing, a charging module is added to household appliances, that is, after an abnormal power failure, the charging module supplies power to the sampling module. However, the reasons for power failure of household appliances are not limited to abnormal power failure, but also include unstable power frequency lines. (short time), or the user shuts down the appliance normally

Abstract

The invention provides a power-off memory module, a master control circuit, an information reading method and system and a soybean milk machine. The power-off memory module comprises a first diode assembly and a first resistor assembly, which are connected in parallel; and a first electrolytic capacitor, wherein one common port of the first diode assembly and the first resistor assembly is connected to a power-off memory terminal of the master control circuit; the positive end of the first electrolytic capacitor is connected to the other common port of the first diode assembly and the first resistor assembly; and the negative end of the first electrolytic capacitor is grounded. Through the technical scheme, after the master control circuit powers off and regains power, power-off record can be accurately judged, and sampling information at the power-off time can be read quickly to control the load to work continuously according to the sampling information.

Description

technical field [0001] The present invention relates to the technical field of household electrical appliances, and more specifically, relates to a power-off memory module, a main control circuit, an information reading method, an information reading system and a soybean milk maker. Background technique [0002] In related technologies, household appliances (such as soybean milk machines, washing machines, televisions, and refrigerators, etc.) usually experience abnormal power outages due to failures in power frequency lines. In order to ensure that the sensor modules of household appliances can continue to be For sampling processing, a charging module is added to household appliances, that is, after an abnormal power failure, the charging module supplies power to the sampling module. However, the reasons for power failure of household appliances are not limited to abnormal power failure, but also include unstable power frequency lines. (short time), or the user normally tur...
