Intelligent programmable building block toys based on nfc

Abstract

The invention discloses an intelligent programmable building block toy based on NFC. The intelligent programmable building block toy comprises a plurality of NFC antennas, a controllable multi-way switching circuit, an NFC read-write unit, a singlechip and a runner, wherein building blocks are placed on the NFC antennas; an NFC label is built in each building block; the input end of the controllable multi-way switching circuit is connected with the plurality of NFC antennas; the first input end of the NFC read-write unit is connected with the controllable multi-way switching circuit, and the second input end of the NFC read-write unit is connected with the output ends of the plurality of NFC antennas; the input end of the singlechip is connected with the NFC read-write unit, and an address control end of the singlechip is connected with an address line of the controllable multi-way switching circuit; and the runner is used for sequentially running procedure codes on NFC labels, and driving an actuator to carry out corresponding actions according to the running result. According to the invention, the NFC technology is applied to the building block toy, and the children experience the interest of programming through the form of piling up the building blocks, therefore, the building block toy not only is the splicing and combing in special shape, but only enhances the attraction for the children.

Description

technical field [0001] The invention relates to an intelligent programmable building block toy based on NFC. Background technique [0002] NFC near-field communication technology is evolved from non-contact radio frequency identification (RFID), which can identify and exchange data with compatible devices within a short distance. The operating frequency is 13.56MHz. [0003] The NFC antenna is a near-field coupling antenna. Since the 13.56Mhz wavelength is very long and the reading and writing distance is very short (within 20cm, if the antenna is small, it can be shorter), the coupling method used by NFC is magnetic field coupling. [0004] The existing ordinary children's building blocks are made of wood, plastic, and metal. Building blocks are only the splicing and combination of spatial shapes, and can only realize the functions of building and arranging. The expansion function of building blocks is almost zero, and their appeal to children is limited. Although every c...
