Alternatively, the path between the second power source and the controller may be normally closed, so that the controller only draws power from the first power source when the first power source is supplying power.
Optionally, a relay switch is connected between the second power supply and the controller, the relay switch is powered by the first power supply, when the first power supply is powered, the relay switch is in an open state, and a path between the controller and the second power supply is disconnected; when the first power supply is powered off, the relay switch is in a closed state, and the second power supply is electrically connected with the controller.
Optionally, when the terminal detects that the first power supply is not powered off, the first power supply is adopted to supply power to the floor heating system, and normal operation of the floor heating system is maintained through the first power supply. Meanwhile, the storage battery corresponding to the second power supply is charged through the first power supply.
Optionally, when the terminal detects that the first power supply is powered off, the second power supply is started to supply power to the temperature detection device and the processing device in the floor heating system through the second power supply. The second power supply is electrically connected with the temperature detection device, and the second power supply is electrically connected with the processing device.

Optionally, the first temperature threshold is greater than the freezing point temperature, and the value range of the first temperature threshold may be selected from 1 ℃ to 10 ℃.
Optionally, because the range that general floor heating pipe was laid is great, the different circumstances of temperature may appear in the water in the same underfloor heating system, consequently, when processing apparatus was the water pump of floor heating pipe intercommunication, the terminal can be and launch first water pump, made the water circulation in the floor heating pipe flow through first water pump to make the water in the floor heating pipe reach the temperature balance, in order to heat up to the pipeline that part water temperature is low.

Optionally, the first preset time period may be a preset fixed time period (a value of the first preset time period may range from 3 hours to 5 hours); the first preset time period may also be determined according to the electric quantity of the second power supply, and the more the remaining electric quantity of the second power supply, the longer the first preset time period.
Further, the first preset time is longer than or equal to the time required by one-time circulation of water in the pipeline of the floor heating system.
Optionally, after the first preset time period, if it is detected that the current water temperature is greater than or equal to the first temperature threshold (i.e., the temperature is raised through water circulation), the first water pump is turned off, and at this time, the drain valve does not need to be opened to drain water. Therefore, the misjudgment of the actual water temperature caused by the unbalanced water temperature in the floor heating system can be avoided, and meanwhile, the drainage measures are avoided as far as possible, so that the effect of effectively saving water resources is achieved.
Optionally, after a first preset time, if it is still detected that the current water temperature is less than the first temperature threshold, the drain valve is opened to drain water in the floor heating pipe, so as to prevent water from freezing in the pipeline of the floor heating pipe.
Alternatively, when the drain valve is opened to drain, the first water pump may be kept running, so that the drainage speed of the water in the pipeline may be increased.
In another embodiment, as shown in fig. 10, the method of step S40 may be implemented by: the floor heating system further comprises a time delay relay 120, the time delay relay 120 being arranged in the circuit between the second power source (not shown) and the drain valve 100 as a second switch of the circuit between the second power source and the drain valve 100.

The delay time of the delay relay is a first preset time, timing is started when the current water temperature is smaller than a first temperature threshold value, and after the timing is finished, the delay relay closes a second switch of a circuit between a second power supply and the drain valve. The second power supply will only supply power to the drain valve when the first switch and the second switch of the circuit between the second power supply and the drain valve are closed simultaneously.
