Description

Technical Field

[0001] The present invention relates to the technical field of intelligent floor tiles, and particularly to a graphene intelligent induction floor tile. Background Art

[0002] In recent years, the world real estate industry has developed rapidly, leading to significant growth in the production and consumption of floor tiles worldwide. Due to the wide variety of colors and patterns, large quantity, good quality, availability of high, medium, and low-grade products, large selection, and reasonable prices of Chinese floor tile products, many countries and regions around the world highly favor Chinese floor tile products. The proportion of Chinese floor tiles in the international market is increasing day by day. While focusing on external aesthetics, domestic floor tiles also pay more attention to the development of functions.

[0003] With the continuous development of the social economy, people's requirements for the quality of life are getting higher and higher, which is particularly prominent in housing decoration. Floor tiles are an essential decorative material for house decoration. They are made of refractory metal oxides and semi-metal oxides through processes such as grinding, mixing, pressing, glazing, and sintering, and form an acid and alkali-resistant porcelain or stone-like building or decorative material, collectively called floor tiles; their raw materials are mostly mixed from clay, quartz sand, etc.

[0004] There is a patent with the patent number CN110158910A named a safe graphene carbon crystal heating floor tile. This patent includes a base layer, an intermediate layer, a surface layer, and a waterproof membrane; an intermediate layer is provided between the base layer and the surface layer, and the intermediate layer is composed of a heating layer, a heat storage layer, a heat dissipation panel, a heat insulation layer, a heat insulation coating layer, and a heat insulation and flame retardant layer; a nano-carbon crystal graphene heating chip is provided in the heating layer; a male head and a female head are provided on the heating layer; a ground wire is connected to the male head; the male head and the female head cooperate with each other; a heat storage layer is provided above the heating layer; a heat dissipation panel is provided between the heat storage layer and the top surface layer; a heat insulation layer is closely provided at the bottom of the heating layer, and a heat insulation coating layer is provided on the outer wall of the heat insulation layer; a heat insulation and flame retardant layer is provided below the heat insulation layer; the waterproof membrane is wrapped around the bottom and the periphery of the intermediate layer. The structure design is reasonable, with good waterproof performance, avoiding the drawbacks existing in the prior art, greatly improving the safety of use; energy-saving, environmentally friendly, the environment is not dry and comfortable; and it is convenient for installation and use, that is, it can be heated immediately, with electronic intelligent temperature control; the power does not decay during long-term use, and the normal working life is greater than 100,000 hours; it has a health care and physiotherapy effect, with a wavelength of 8 - 18 microns. People staying in this environment for a long time is beneficial to physical health; relying on the principle of cold and hot air convection, it is quiet and noiseless.

[0005] However, for existing heated floor tiles laid in indoor areas, synchronous heating and adjustment are carried out to ensure that each floor tile heats up, thereby ensuring the indoor temperature and the comfort of people. However, if simultaneous heating is carried out at the locations of people's movement trajectories, people's positions, and all the places where indoor items are placed, heating in positions where people do not move will cause waste. Especially in the south where there is no underfloor heating indoors, the simultaneously heated floor tiles may affect the functions of household appliances such as refrigerators. Summary of the Invention

[0006] The purpose of this solution is to provide a graphene intelligent induction floor tile to achieve the purpose of synchronous heating for human movement.

[0007] To achieve the above purpose, this solution provides a graphene intelligent induction floor tile, including:

[0008] A floor tile body, with a heating film and graphene heat conduction conduits provided at the bottom of the floor tile body;

[0009] A collection and preprocessing module, used to collect the pressure change situation of the floor tile body and generate a pressure signal; a gait collection module collects the position where the pressure of the floor tile body changes and generates a gait signal;

[0010] A processing module, when receiving a pressure signal, generates an execution instruction; if no pressure signal is received, no execution instruction is generated; receives the gait signal, presets the positions of adjacent floor tile bodies of the gait signal, and generates a heating instruction;

[0011] An execution module, receives the execution instruction and the heating instruction, and controls the heating film to be powered on.

[0012] Beneficial effects of this solution: (1) Ensure the heating requirements of the heated floor tiles and meet the heating for human activities.

[0013] (2) For positions that are not needed, heating will not be carried out. Heating is carried out at the positions where people arrive, which is more targeted and ensures that heating will not cause waste.

[0014] (3) Collect signals of changing pressure, filter the situation of being pressed on the floor tile, filter the positions where pressure is given by furniture over time, and thus heat more precisely for human movement.

[0015] (4) Utilize gait collection to be able to preheat the movement trajectory of the actor in advance, ensuring that when a person walks to the position, the temperature of the floor tile body is appropriate.

[0016] Furthermore, an insulation layer is provided below the heating film.

[0017] Furthermore, the elastic rubber pad contains graphene and conductive fillers.

[0018] Further, a number of reserved holes for quickly conducting heat to the floor tile surface are provided in the elastic rubber pad and the lower layer structure.

[0019] Further, the pressure sensing module is arranged in the groove of the lower layer structure, and the pressure sensing modules are interconnected; the pressure sensing module is also used to collect the pressure change of the overlapping part of the boss and the groove after the floor tile body is pressed, as well as the quantity and position of the pressure signals generated by the floor tile body, and generate numerical signals and position signals; the processing module is used to receive the numerical signals and position signals, judge that there is a blank area without generated position signals inside the closed figure formed by the position signals with the same pressure signal, set the threshold value of the numerical signal to 8, if the numerical signal is less than or equal to 8, no instruction is generated; if the numerical signal is greater than 8, and there is a blank area without generated position signals inside the closed figure formed by the position signals with the same pressure signal, a warning instruction is generated; the execution module, the execution module includes an alarm, and the execution module is connected to the smart phone via Bluetooth; if a warning instruction is received, an alarm is issued, and at the same time a reminder is sent to the smart phone.

[0020] Further, a temperature sensor is arranged inside the floor tile body, and the threshold value of the temperature sensor is set to 30 °C.

[0021] Further, the processing module is also used to predict the next floor tile body that will generate a pressure signal according to the pressure signal corresponding to each floor tile body. The pressure signal includes time information and pressure value information. The processing module is also used to perform self-learning on the correlation between the floor tile bodies according to the pressure value information and time information by using a preset neural network model, and output a prediction result, and then output a preset instruction to the floor tile body corresponding to the prediction result to control the heating film to be powered on.

[0022] Further, after receiving the numerical signal and the position signal, the processing module is also used to judge whether the numerical signal of the floor tile body at the same position or adjacent positions changes suddenly and generates a peak value. If it does, it indicates that the user may be walking rapidly or has fallen. At this time, the change situation of the numerical signal at the previous moment is called. If the change situation of the numerical signal at the previous moment still has a peak value, it indicates that the user is walking rapidly. If the change situation of the numerical signal at the previous moment does not have a peak value or is lower than the normal numerical signal, it indicates that the user has slipped or fallen. At this time, a warning instruction is generated; if there is a superposition relationship between the numerical signals of adjacent or similar floor tile bodies, it indicates that the user may be carrying or placing an object. At this time, a reminder instruction is generated. Description of the Drawings

[0027] The following is a further detailed description through specific implementation manners:

[0028] The markings in the attached drawings of the specification include: upper layer structure 1, lower layer structure 2, elastic rubber pad 3, pressure sensing module 4, heating film 5, heat insulation layer 6, and reserved hole 7.

[0029] As shown in the attached Figure 1 and Figure 4 figures:

[0030] A graphene intelligent sensing floor tile includes:

[0031] The floor tile body, which is composed of upper and lower layer structures. An elastic rubber pad 3 is embedded in the upper layer structure 1, and there are convex platforms arranged uniformly in an array on it; there are grooves corresponding to the convex platforms at the top of the lower layer structure 2 (in this embodiment, the concave angle is slightly smaller than the convex angle), a pressure sensing module 4 is provided at the bottom of the groove, and a heating film 5 is provided at the bottom of the lower layer structure 2;

[0032] As shown in Figure 2 and Figure 3 the figures:

[0033] In the state where there is no pressure on the floor tile, there is a gap of 3 - 5 mm between the upper and lower layers; when the floor tile is under pressure, the convex platforms of the elastic rubber pad 3 fill the grooves. At this time, the resistance value of the sensing module changes, thereby generating a pressure signal;

[0034] The pressure sensing module 4 is used to collect the pressure change situation of the overlapping part of the convex platform and the groove after the floor tile body is pressed, and generate a pressure signal;

[0035] The processing module is used to receive the pressure signal array, obtain the human gait change signal after processing, and generate an execution instruction; if no pressure signal is received (that is, the pressure does not reach the opening value of the sensing module), no execution instruction is generated; the position of the adjacent floor tile to the floor tile body for collecting the gait signal is preset, and a heating instruction is generated;

[0036] The execution module receives the execution instruction and the heating instruction, and controls the heating film 5 to be powered on.

[0037] An elastic rubber pad 3 is embedded in the upper structure 1, and a heating film 5 and a heat insulation layer 6 below the heating film 5 are provided in the lower structure 2. Graphene and conductive fillers are mixed in the elastic rubber pad 3. The graphene material has excellent heat conduction performance, and the thermal conductivity coefficient is as high as 5300 W / m·K. A number of reserved holes 7 for quickly conducting heat to the floor tile surface are provided between the elastic rubber pad 3 and the lower structure 2. The double-layer structure of the floor tile body with the cooperation of the groove and the boss can improve the supporting force of the floor tile itself, and at the same time, during the heating process, it will not cause scalding to the human body by the heating layer; at the same time, the reserved holes 7 ensure the space for thermal expansion and contraction.

[0038] The pressure sensing module is arranged in the groove of the lower structure, and the pressure sensing modules are connected to each other; the pressure sensing module is also used to collect the pressure change of the overlapping part of the boss and the groove after the floor tile body is pressed, and collect the quantity and position of the pressure signals generated by the floor tile body, and generate a numerical signal and a position signal; the processing module is used to receive the numerical signal and the position signal, judge that there is a blank area where no position signal is generated inside the closed figure formed by the position signals with the same pressure signal, set the threshold of the numerical signal to 8, if the numerical signal is less than or equal to 8, no instruction is generated; if the numerical signal is greater than 8, and there is a blank area where no position signal is generated inside the closed figure formed by the position signals with the same pressure signal, a warning instruction is generated; the execution module, the execution module includes an alarm, and the execution module is connected to the smart phone via Bluetooth; if a warning instruction is received, an alarm is issued, and at the same time, a reminder is sent to the smart phone.

[0039] For example, when moving indoors, the maximum number of floor tile bodies that the feet can contact is 8. If there are children or the elderly at home, when they fall, the pressure conditions are different. The numerical signals contacted by children and the elderly when they fall are different, and the pressure conditions are also different. If the pressure changes during the handling of objects, and then through acoustic wave detection and judging whether there is a blank area generated inside the closed figure formed by the position signals. Because no matter whether the elderly or children fall, there must be no blank area inside the closed figure formed by the position signals, so if the numerical signal is greater than 8, a warning instruction is generated; it is judged that someone has fallen, and after receiving the warning instruction, an alarm is issued, and at the same time, a reminder is given to the smart phone.

[0040] A temperature sensor is provided inside the floor tile body, and the threshold of the temperature sensor is set to 30°C. A temperature sensor is provided inside the floor tile body, and the threshold of the temperature sensor is set to 30°C. A fast heat conductor is provided inside the floor tile body. It can quickly supply heat while preventing scalding caused by too high temperature. At the same time, it prevents potential safety hazards caused by too high temperature.

[0041] The processing module is also used to predict the next floor tile body that generates a pressure signal according to the pressure signal corresponding to each floor tile body. The pressure signal includes time information and pressure value information. The processing module is also used to perform self-learning on the correlation change between floor tile bodies according to the pressure value information and time information by using a preset neural network model, and output a prediction result, and then output a preset instruction to the floor tile body corresponding to the prediction result to control the heating film to be powered on.

[0042] For example, it is possible to predict the user's movement trajectory based on the time and pressure value when the floor tile body is under pressure, and then preheat in advance, which can ensure that the soles of the feet can be heated when the user moves, and prevent the user from leaving this floor tile body too quickly when the heating film is heating.

[0043] The processing module is also used to, after receiving the numerical signal and the position signal, determine whether the numerical signal of the floor tile body at the same position or adjacent positions has a sudden change (i.e., the change exceeds the threshold) and generates a peak value. If so, it indicates that the user may be walking rapidly or has fallen. At this time, the change situation of the numerical signal at the previous moment is called. If the change situation of the numerical signal at the previous moment still has a peak value, it indicates that the user is walking rapidly. If the change situation of the numerical signal at the previous moment does not have a peak value or is lower than the normal numerical signal, it indicates that the user has slipped or fallen, and a warning instruction is generated at this time; if there is a superposition relationship between the numerical signals of adjacent or similar floor tile bodies, it indicates that the user may be carrying or placing an object, and a reminder instruction is generated at this time.

[0044] For example, when a child or an old person falls indoors, it is judged according to the numerical signal at the previous moment. If a normal user walks or jumps quickly, the gravity will fall on the floor tile body. Similarly, at the previous moment, the floor tile body received the same gravity and was at a peak value. However, when an old person or a child falls, the gravity received by the floor tile body at the previous moment will be less than its own gravity, that is to say, the gravity received by the floor tile body at the previous moment is less than the gravity received by the floor tile body at the moment before the previous moment. Therefore, if there is no peak value or the numerical signal is lower than the normal numerical signal in the change of the numerical signal at the previous moment, it means that the user has fallen or slipped.

[0045] In this embodiment, if the pressure change is caused by people carrying items, the positions with the same pressure signal represent the same item or the same person. If the pressure signals are two different magnitudes, it means that they are not related, and they can be excluded in the processing module.

[0046] The above are only embodiments of the present invention, and common knowledge such as specific structures and characteristics known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope claimed in this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
