Abstract
The invention discloses a kindergartener-receiver ID authenticating system based on fingerprint identification technique, belonging to the application of MCU technique to the control field, comprising fingerprint identification systems, MCU and voice prompt device, and characterized in that: the switching signal output ends of two fingerprint identification systems are connected with input end of the MCU, and output end of the MCU is connected with a programmable voice prompt IC (integrated circuit). The invention identifies the switching signals of the two fingerprint identification systems by the MCU, and gives a sound signal prompt if the IDs of the kindergartener and receiver are confirmed at the same time and otherwise gives an alarm signal. The invention effectively protects the received kindergartener and is widely applied to the places that need the two-party ID identification, such as kindergartens, etc.
Description
Technical field the invention belongs to singlechip technology in the control Application for Field.
Before background technology the invention applying date, the known technology fingerprint identification technology is controlled in order to the gate inhibition mostly, and use control one to one, do not relate to as yet and adopt two groups of fingerprint recognition systems to judge that by computer logic the method for the true and false is in order to the infant school child taking authentication.
The purpose of summary of the invention the invention provides a kind of infant school child taking identity authorization system based on fingerprint identification technology.
The invention solves the technical scheme that its technical matters adopts: comprise fingerprint recognition system, single-chip microcomputer and sound prompt device; The switching signal output terminal of two groups of fingerprint recognition systems is connected with the I/O input end of single-chip microcomputer, and the output terminal of single-chip microcomputer is connected with voice suggestion integrated circuit able to programme.
Verbal cue integrated circuit able to programme is the ultra-large CMUS integrated circuit of self-adaptation pulse-code modulation speech synthesis technique, form by circuit units such as circuit such as One Time Programmable storage display, clock oscillator, logic controller, pulsed modulation code translator, timing generator, address sequence generator, driver, voltage driver, current drivers, its trigger end is connected with the single-chip processor i/o output terminal, high level is effective, and its current output terminal drives loudspeaker by the NPN triode.
The beneficial effect of the invention is: the invention is by the identification of single-chip microcomputer to the switching signal of two groups of fingerprint recognition systems, picked and given the audio communication prompting when children's identity and the person's of picking identity are confirmed simultaneously, when the identity of being picked children and the person's of picking identity can not be confirmed simultaneously, given alerting signal.The present invention is by effectively protecting the safety of being picked children to the person of picking with the quilt affirmation of the person's of picking fingerprint recognition signal.To be widely used in the place that kindergarten etc. need pick both sides' authentication.
Description of drawings Fig. 1 is the electrical schematic diagram of the invention.
Embodiment is consulted Fig. 1.Single-chip microcomputer adopts the 8-bit microcontroller PIC16C54 of U.S. MICROCHIP company among the figure.The invention fingerprint recognition system is a known technology, and its two groups of fingerprint recognition systems are respectively in order to the collection person of picking with by the person's of picking fingerprint, and is stored in the system.The switch that refers to other recognition system is output terminal S
