In practical applications, a control panel may be connected between the inverter 20 and the temperature control unit 30, and the control panel is used to control the solar photovoltaic panel 10 to supply power to the heat accumulating type heating floor tile 50.
Referring to fig. 1, a radar detection unit 40 is connected to a temperature control unit 30, the radar detection unit 40 may transmit a 77-81 GHz signal and recover a feedback signal, then perform various arithmetic operations on the feedback signal to achieve the collection of behavior patterns such as human body positioning and motion state detection, and then form user daily behavior data by collecting a large amount of behavior pattern data and send the user daily behavior data to the temperature control unit 30; after receiving the data, the temperature control unit 30 designs an appropriate heating temperature required by the daily life habits of the user, that is, the habit heating temperature of the user, through the programmed program.

The heat accumulating type heating floor tile 50 is composed of a floor tile body 51, an aluminum plate, an encapsulated heating chip 55, a heat accumulating plate 53 and a heat insulating layer 54. In the daytime, when the voltage stabilized by the inverter 20 is used for heating the heat accumulating type heating floor tile 50 according to the instruction through the control panel and the temperature control unit 30, the packaging heating chip 55 contained in the floor tile can heat quickly, the heat accumulating plates 53 around the packaging heating chip 55 can accumulate heat, and the aluminum plate can enable the surface of the floor tile to heat uniformly. When the sunshine is not full at night, the packaging heating chip 55 cannot heat, the heat energy absorbed by the heat storage plate 53 in the daytime can be released at night, and the aluminum plate utilizes the heat emitted by the heat storage plate 53 to enable the surface of the floor tile to uniformly heat.
In the embodiment of the present invention, the radar detection unit 40 includes a detection subunit, an information processing subunit, and a big data processing subunit; the detection subunit is used for transmitting a detection signal and receiving a feedback signal of a human body.

Specifically, since the application scenario is an indoor environment, multipath effect may be generated, and in order to remove interference caused by multipath effect, a static cancellation algorithm needs to be used; in order to remove interference such as environmental noise, a CFAR algorithm is required; because the height of a person is far greater than the distance resolution of a radar, different target information can be generated at different parts of the person after radar waves are reflected by the human body, and therefore a target agglomeration algorithm is needed to be used for clustering the target information corresponding to the different parts; and finally, realizing the functions of human body positioning and motion state detection through a positioning and motion state detection algorithm.
And the big data processing subunit is used for acquiring the daily behavior data of the user according to a large amount of human body positioning information and motion state information.

The laid heat accumulating type heating floor tiles 50 are connected in parallel with the temperature control unit 30, and the temperature control unit 30 controls the heat accumulating type heating floor tiles 50 to heat and accumulate heat indoors according to the set heating temperature. At night, when the solar photovoltaic panel 10 cannot generate electric energy, the heat accumulating type heating floor tiles 50 release the heat accumulated in the daytime to heat the indoor.
Further, the heating system further comprises a mobile terminal 60, and the mobile terminal 60 is wirelessly connected with the temperature control unit 30; the temperature control unit 30 is further configured to receive an input temperature sent by the mobile terminal 60, and control the heat accumulating type heating floor tile 50 to work according to the input temperature.

The system forms an intelligent energy-saving closed-loop heating system through photovoltaic power generation, radar detection, temperature control and the heat accumulating type heating floor tiles 50. Based on the daily life behavior data that radar detection unit 40 gathered, temperature control unit 30 can be connected with cell-phone APP according to the suitable heating mode of the automatic execution of the custom of every family, also can look over the indoor heating condition.
In order to ensure that the heat storage plate 53 of the heat storage type heating floor tile 50 can store heating heat at night, the temperature control system can execute a 2-hour highest temperature mode to store energy for the heat storage plate 53 when the sunshine is strongest every day (the highest temperature is within the acceptable range of human bodies, and the highest temperature is higher than the habitual heating temperature). At night, in order to simplify heating, when a user moves in one room, the temperature control unit 30 performs a suitable heating temperature for the room through radar detection, and other rooms adopt a low-temperature heating mode; when a resident enters sleep, the temperature control unit 30 adopts a heating mode suitable for sleep, so that the temperature of a bedroom is increased, and the heating temperature of other rooms is reduced. When the resident has special circumstances or needs, the resident can use cell-phone APP remote control heating temperature. The electric energy that leans on the photovoltaic to produce heats when sunshine is full, and the unnecessary electric heat energy that the photovoltaic produced is stored in heat accumulation board 53 of heat accumulation formula heating ceramic tile 50, leans on heat accumulation board 53 heating when sunshine is not full, and the mode through taking heating as required can not only ensure customer's heating and experience, can also reduce the loss of heat energy, finally reaches green energy-conserving purpose.
