The invention belongs to the field of domestic appliances, and particularly relates to a low-power consumption remote controller, a temperature sampling control system and a temperature sampling control method. According to the remote controller, the temperature sampling system and the temperature sensing control method, provided by the invention, a first preset level is output by an IO (Input Output) port of a microprocessor MCU (Micro Controller Unit) so as to enable voltage difference to exist between a reference resistor R1 and a thermistor RT, voltage sampling is respectively carried out through a first AD (Analog to Digital) sampling port and a second AD sampling port, a resistance value of the thermistor RT can be calculated through a voltage division formula, and a temperature parameter value corresponding to the resistance value can be obtained. The remote controller, the temperature sampling system and the temperature sensing control method, provided by the invention, have the main advantages that the first preset level is output by the IO port of the microprocessor MCU, and thus sampling voltage is supplied; but most of the time, the IO port is used for outputting a second preset level, thus the whole temperature sampling control system is enabled to be in a standby non-sampling state, power consumption cannot be generated, and the temperature sampling control system is in a low-power consumption state for a long time; in addition, the temperature sampling control system is simple in structure and low in cost, and the temperature sampling control method also has the advantages of convenience, low cost and strong transportability.
Description
technical field [0001] The invention belongs to the field of household electrical appliances, and in particular relates to a low-power remote controller, a temperature sampling control system and a control method. Background technique [0002] At present, most home appliances need to sample the temperature sensor (thermistor RT). The traditional method is to use such as figure 1 The structure shown is carried out: use two resistors (thermistor RT and resistor R1) in series to divide the voltage, and carry out AD conversion through the microprocessor MCU to complete the temperature sampling. However, this circuit will generate power consumption P=U*U / (RT+R1) for a long time. In this formula, U is the power supply voltage, RT is the resistance value of the thermistor, and R1 is the resistance value of the voltage divider resistor. Therefore, when this temperature sampling circuit is applied to a remote control of a home appliance, the life of the battery will be greatly short...
