Description

Piezoelectric and solar complementary smart luminous floor

technical field

The invention relates to a luminous floor, in particular to an intelligent floor capable of pre-luminous and automatic charging.

Background technique

Flooring is the surface layer of the ground or floor of a building, made of wood or other materials. There are many classifications of floors, classified by structure: solid wood floor, laminated composite wood floor, bamboo wood floor and the most popular multi-layer solid wood composite floor, etc.; classified by use: household, commercial, anti-static floor, sports hall Special floor for venues, special floor for track and field, etc. In addition, there are some floors with specific functions formed by adding special structures to the basic floor. The luminous floor is a special floor, which is mostly used in stairs, living rooms, children's activity places, etc.

The luminous floor is generally a multi-layer composite floor with a luminous layer in the middle. The light-emitting mechanism of the existing luminescent layer mainly uses two kinds of luminescent powder and LED lamp; the electric intensity required by the luminescent powder is not high, but the light is weak; the luminous intensity of the LED lamp is high, but requires a stable power supply with high intensity. Therefore, the power supply mode of the LED power supply is one of the improvement directions of the luminous floor.

A kind of smart floor as disclosed in patent CN 203320895 U, includes a substrate with an inner cavity, and a light-transmitting surface plate that is covered on the substrate and matches the substrate, and a charging device is arranged in the inner cavity and a light-emitting device, wherein, the charging device generating sets, each generating set includes an iron ring, a copper coil, a permanent magnet and an aluminum plate; the permanent magnet is fixedly connected to the lower part of the transparent surface plate, and the inner cavity The bottom surface is evenly distributed with a plurality of reset elastic devices; the light emitting device includes LED lamps and rechargeable batteries forming electrical connections; the generating sets are respectively electrically connected to the rechargeable batteries.

The above-mentioned technical solution only has a single power supply mode, which cannot make full use of the conditions to generate electric energy. When people walk less on the floor, only the electric power generated by the cutting magnetic field may be insufficient to complete the power supply task. Furthermore, when people walk at night, it may be inconvenient to turn on the lights, or they need to see the road ahead in advance. Ordinary luminous floors cannot intelligently identify the direction of people's walking, which brings certain difficulties to the speed and safety of people's walking.

Contents of the invention

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

The intelligent light-emitting floor complementary to piezoelectricity and solar energy is composed of three layers. The first layer includes a transparent plate, a soft material, and a protruding cylinder arranged at the center of the transparent plate. The transparent board is surrounded by high-quality materials; the second layer mainly includes PVC board A and the piezoelectric power generation sheet embedded on the PVC board A, solar power generation board, photoresistor, LED lights, and the piezoelectric power generation board and the protrusion of the first layer.

The module and the infrared receiving tube are all connected with the single-chip microcomputer, the single-chip microcomputer is connected with the LED lighting module, and the single-chip microcomputer is connected with the infrared emitting tube.

Some nouns are explained as follows:

The infrared pair tube refers to an infrared emitting tube and an infrared receiving tube located in the same wedge-shaped concave-convex groove. The infrared tube module refers to the infrared tubes and their connecting circuits.

PVC board is a new type of light-weight floor decoration material, also known as "light-weight floor material". PVC board refers to the floor made of polyvinyl chloride material. Fillers, plasticizers, stabilizers, colorants and other auxiliary materials are produced on the sheet-like continuous substrate by coating process or calendering, extrusion or extrusion process.

A supercapacitor is an electrochemical element that stores energy from a polarized electrolyte. It is different from a traditional chemical power supply. It is a power supply with special properties between a traditional capacitor and a battery. It mainly relies on the electric double layer and The redox pseudocapacitive charge stores electrical energy, but no chemical reaction occurs during the energy storage process. This energy storage process is reversible, and it is precisely because this supercapacitor can be repeatedly charged and discharged hundreds of thousands of times. Its basic principle is the same as that of other types of electric double layer capacitors. It uses the electric double layer structure composed of activated carbon porous electrodes and electrolytes to obtain super large capacity. The advantages of supercapacitors: the capacitance of the Farad level can be reached in a very small volume; special charging circuits and control discharge circuits are required; compared with batteries, overcharging and overdischarging will not have a negative impact on its life; It is a green energy source; supercapacitors can be welded, so there are no problems such as weak battery contacts.

Owing to adopting above-mentioned technical scheme, the technological progress that the present invention obtains is:

The invention can intelligently judge the walking direction of a person and turn on the light in advance; the charging mechanism is reasonable to ensure the normal power supply of the device; the signal transmission is accurate and the assembly and disassembly are convenient.

The solar power generation module and the piezoelectric power generation module are connected in parallel, and then connected to the supercapacitor through a diode. When the solar energy can be received, the solar power generates electricity and stores it in the supercapacitor; when someone passes by, the piezoelectric power generation module generates electricity and stores it in the supercapacitor. Capacitor; two generator mechanisms ensure that the supercapacitor can get enough power to ensure the normal operation of the whole device; the supercapacitor is small in size, large in capacity, easy to connect, and has a long service life, while the power supply in the floor needs to be able to charge and discharge repeatedly, Long-life power supply, so supercapacitors are ideal for use in floors.

The photoresistor is connected to the single-chip microcomputer to ensure that the LED light is not on during the day; the piezoelectric power generation module is connected to the single-chip microcomputer. The LED lamp lighting module sends out a signal, and the LED lamp lighting module lights up the LED lamp.

A pair of infrared receiving tubes and infrared emitting tubes are installed in the wedge-shaped concave-convex grooves of the third layer. The signal emitted by the single-chip microcomputer of the local plate is transmitted to the corresponding infrared receiving tube of the adjacent floor plate, so as to realize the transmission of the signal, and the pre-lighting is realized after being processed by the single-chip microcomputer.

The third layer of the floorboard is a wedge-shaped concave-convex groove structure, and an infrared receiving tube and an infrared emitting tube are installed in the wedge-shaped concave-convex groove, because the infrared receiving tube should be in a straight line with the infrared emitting tube in the adjacent edge of the floorboard Relatively placed to ensure the accurate transmission of infrared light signals, the wedge-shaped concave-convex grooves between adjacent floor boards are spliced, and the wedge-shaped concave-convex grooves have been designed and produced to ensure that the corresponding infrared emitting tubes and infrared receiving tubes are aligned and placed, reducing infrared signals The possibility of poor transmission; straight-sided floors, especially those equipped with infrared emitting tubes and infrared receiving tubes, need to be carefully matched, and the installation is time-consuming and labor-intensive.
