A time-period-based thermal storage boiler control method based on a thermal resistor and a thermocouple. The method includes controlling the temperature according to time periods and dividing a day into a peak time period, a flat time period and a trough time period; heating a heat accumulator in a boiler through electric heating to convert the electrical energy into heat to be stored in the heat accumulator; stopping heating through a controller when a sensor detects that the heat accumulator reaches a set temperature; and starting a heat exchange fan to transfer the heat energy in the heat accumulator to a heating system when the heating is needed; wherein the heating temperatures in the peak time period, the flat time period and the trough time period are set through a Modbus protocol. The time-period-based thermal storage boiler control method based on the thermal resistor and the thermocouple is designed in a differentiation mode and utilizes a control way based on the time periods and rate electric cha
