Problems solved by technology

[0007] From the above patent search results, we can find that most of the patents on the implementation of abacus in the domestic patent database are static digitalization of the abacus or abacus calculation in the way of state judgment, and the results are only in the digitization itself. There is no innovation or change in the process, method and interaction mode of the abacus application

Embodiment Construction

[0024] The invention provides an acoustic feedback type force-sensing abacus calculation device and method. As shown in Figure 1. The device uses a PVDF piezoelectric film as a sensor 1 for detecting force signals. The film is trial-produced into a thin sheet with a size of 10mm*4mm, and leads 4 are drawn from both ends to transmit the charge signal to the amplifier circuit 5 . The film and the wires are packaged and tightly attached to the surface of the specific beads 2 on the bead rod 3. The wires 4 pass through the small holes on the surface of the beads 2 and lead to the amplifier circuit 5 on the circuit board below the beads. The amplifier circuit 5 Connected with the data acquisition module 6, the output charge signal is amplified into a voltage signal through the amplifier circuit 5 composed of two AD620 amplifier chips, and then converted into a digital electrical signal by a data acquisition module 6 and output to the computer 7. The computer 7 outputs a control si...

Abstract

The apparatus uses PVDF piezoelectric thin film as the sensor to detect force signals; the lead-out wires from both ends are connected to the amplifier circuit; the thin film and wires are packed and are closely pasted on the surface of abacus balls; the wires passes through the small hole on the abacus balls to connect to the PCB under the abacus balls; the outputted charge signals are amplified by an amplifying circuit composed of two AD620 amplification chips, and are converted to digital signals by using a data collection board, and then are transmitted to a computer.

Description

technical field [0001] The invention belongs to the technical scope of digital data processing, and in particular relates to a sound feedback type force-sensing abacus device and method for data identification, data representation, recording carrier and recording carrier processing. Background technique [0002] Abacus and abacus technology are the cultural treasures of the Chinese nation and the precious wealth left by our long civilization. From a global perspective, before the birth of electronic computers, abacus and abacus technology made a huge contribution to the development of world productivity. From the ditch abacus in the Roman period to the evolution and development of the traditional abacus in China, Russia, and Japan, the history of abacus and abacus technology has always been the result of the continuous development of productivity; for these histories and functions, see the literature "Zhou Quanzhong. Abacus History Some The True Image of Mistakes (continued...
