Figure 2 This is a schematic diagram of the circuit layout structure of the memory metal-based friction nano-reading times counting device described in an embodiment of the present application.
[0030] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a friction nano reading frequency counting device based on memory metal, including a bookshelf 2 and a frequency counting mechanism arranged on the bookshelf 2, the frequency counting mechanism includes a memory metal 8, a pulse trigger module and a pulse counting element 6, the memory metal 8 is installed on the base of the bookshelf 2 and is used to contact the book 1, the pulse trigger module is arranged on the base of the bookshelf 2, and the pulse counting element 6 is connected to the pulse trigger module.
[0031] It should be noted that when the book 1 is taken out from the bookshelf 2, the memory metal 8 is reset along the bookshelf 2, so that the pulse trigger module uses the contact separation friction nano method to generate friction power and obtain power; then when the book 1 is put back into the bookshelf 2, the pulse trigger module transmits the power to the pulse counting element 6, triggering the pulse counting element 6 to work and count the number of times the book 1 is read in the bookshelf 2.

Compared with the traditional radio frequency identification method, the friction nanometer reading times counting device based on memory metal does not require manual operation, which can effectively reduce labor costs; and can count the number of times a book is borrowed each time, especially including the number of times the book is read in the reading room of the library, ensuring the accuracy of the reading times counting, and solving the technical problems that the existing statistical equipment for the reading times of books in the library has a complex structure, difficult installation and low accuracy of the reading times counting.
[0035] It should be noted that the friction nano reading frequency counting device based on memory metal can achieve accurate statistics of book reading times while effectively reducing statistical costs and implementation difficulties.
[0036] like Figure 1 and Figure 2As shown, in one embodiment of the present application, the pulse trigger module includes a first thin film element 3, a second thin film element 4, a first conductive element 5-1, a second conductive element 5-2 and a third conductive element 5-3. The first thin film element 3 is arranged on the lower end surface of the memory metal 8. The second thin film element 4 is arranged on the base directly below the first thin film element 3. The second thin film element 4 is connected to the first conductive element 5-1 through a first wire 9-1. The first conductive element 5-1 is connected to the pulse counting element 6 through a second wire 9-2. The pulse counting element 6 is connected to the third conductive element 9-3 through a third wire 9-3. The two ends of the second conductive element 5-2 are connected to the two ends of the memory metal 8 through a bracket 7. The base is provided with an inner cavity 11 for accommodating the movement of the second conductive element 5-2 and the bracket 7. The first conductive element 5-1 is arranged on the base above the inner cavity 11, and the third conductive element 5-3 is arranged on the base below the inner cavity 11. The second conductive element 5-2 is also grounded through a fourth wire 9-4.
[0037] It should be noted that the first film element 3 can be selected as FEP film, nylon film or graphite film; and / or, the second film element 4 can be selected as a metal film. The metal film can be selected as a gold-plated film made of gold, silver, copper, zinc, chromium or aluminum. Fluorinated ethylene propylene copolymer is referred to as FEP. The first conductive element 5-1, the second conductive element 5-2 and the third conductive element 5-3 are all conductive sheets. The conductive sheet can be selected as a copper sheet, or an iron sheet or an aluminum sheet. The bracket 7 is a connector made of insulating material. In this embodiment, the second film element 4 is preferably selected as an aluminum film. The conductive sheet is preferably selected as a copper sheet. The first film element 3 and the second film element 4 constitute a contact-separation friction nanomodule TENG. The first film element 3 is attached to the lower surface of the memory metal 8 and is directly opposite to the second film element 4 embedded in the groove on the surface of the bookshelf 2. The second film element 4 is connected to the first conductive element 5-1 by a first wire 9-1. The upper end of the bracket 7 is fixed with the memory metal 8, and the lower end of the bracket 7 is provided with the second conductive element 5-2. The bracket 7, the memory metal 8 and the second conductive element 5-2 form a movable joint that can move up and down inside the inner cavity 11. The first conductive element 5-1 is embedded in the central groove on the upper surface of the inner cavity 11, and the third conductive element 5-3 is embedded in the groove on the lower surface of the inner cavity 11, and the centers of the first conductive element 5-1, the third conductive element 5-3 and the second conductive element 5-2 are all on the same line.
[0038] In the embodiments of the present application, the triboelectric series of the FEP film and the aluminum film materials are different. The FEP film is easy to gain electrons and carries a negative charge, while the aluminum film is easy to lose electrons and carries a positive charge.
[0039] It should be noted that the FEP film is a negatively charged film, which carries negative charge. When the distance between the first film element 3 and the second film element 4 in the groove on the upper surface of the bookshelf 2 is reduced until they come into contact, the electrostatic induction effect between the two is enhanced. In this process, the charge will be transferred in a direction, thereby generating an induced current and an electrical signal, which is equivalent to a power source.
[0040] Figure 3 This is a schematic diagram of the working structure of the friction nano-reading number counting device based on memory metal according to an embodiment of the present application. Figure 4 This is a schematic diagram of the working circuit of the memory metal-based friction nano-reading times counting device described in an embodiment of the present application.
[0041] like Figure 3 As shown, in the embodiment of the present application, the working principle of the friction nanometer reading number counting device based on memory metal is: Figure 3 As shown in (a), when the book 1 is pulled out, the memory metal 8 is reset along the arc-shaped guide groove on the bookshelf 2, so that the first film element 3 and the second film element 4 embedded in the groove on the lower surface are separated, and the electrostatic induction effect between the two decreases as the distance increases. The negative charge on the first film element 3 and the positive charge on the second film element 4 are reduced accordingly. At this time, the bracket 7 moves upward inside the inner cavity 11 of the bookshelf 2 as the memory metal 8 is deformed, so that the second conductive element 5-2 is connected to the first conductive element 5-1, and the electrons pass through the fourth wire 9-4, the second conductive element 5-2, the first conductive element 5-1, and the first wire 9-1 from the ground in turn, and finally reach the surface of the second film element 4. Figure 3 As shown in (b), when the book 1 is put back, the memory metal 8 deforms along the arc-shaped guide groove on the bookshelf 2, so that the distance between the first film element 3 embedded in the groove on the lower surface and the second film element 4 in the groove on the upper surface of the bookshelf 2 is reduced until they are in contact, and the electrostatic induction effect between the two is enhanced accordingly, and the negative charge on the third film element 3 and the positive charge on the fourth film element 4 are increased accordingly. At this time, the bracket 7 moves downward inside the inner cavity 11 of the bookshelf 2 as the memory metal 8 deforms, so that the second conductive element 5-2 is connected with the third conductive element 5-3, and the electrons from the surface of the fourth film element 4 pass through the first wire 9-1, the first conductive element 5-1, the second conductive element 9-2, the pulse counting element 6, the third conductive element 9-3, the third conductive element 5-3, the second conductive element 5-2 and the fourth conductive element 9-4 in sequence, and finally lead to the ground. When the book 1 is put back on the bookshelf, the current generated by the first film element 3 and the second film element 4 flows through the pulse counting element 6, thereby completing the counting of the number of readings.
[0042] It should be noted that if Figure 4As shown, the second thin film element 4, the first wire 9-1, the first conductive element 5-1, the second wire 9-2, the pulse counting element 6, the third wire 9-3, the third conductive element 5-3, and the fourth wire 9-4 are connected in sequence, and finally the wires are grounded to realize automatic counting of the number of times books are borrowed.
[0043] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
