Abstract

The utility model relates to a radio frequency identification (RFID) watch which comprises a watchband, a watch body, a watch substrate circuit in the watch body, an RFID switch, an RFID inductor, a controller and an alarm circuit, wherein the RFID switch is arranged on the lateral surface of the watch body and is used for controlling the on/off of the RFID inductor; the controller and the alarm circuit are arranged in the watch substrate circuit; the RFID inductor is connected with the controller through a communication interface; a radio frequency module of the RFID inductor transmits an electronic tag scanning result to the controller; and the controller indicates the alarm circuit to give an alarm when a stored electronic tag exceeds an induction distance. The RFID watch is small and convenient and can assist a user to keep valuables conveniently.

Description

A kind of RFID wrist-watch

Technical field

The utility model relates to a kind of wrist-watch, especially a kind of RFID wrist-watch.

Background technology

Modern society's amusement and recreation product increases, and people often have recreational article with some, as: handheld device, MP3, iPad, mobile phone or the like.When a large number of items carried, it is easy to have forgetful situation, and whenever valuables lost, in addition to a lot of trouble when looking outside, but also wasted a lot of time.The wrist-watch that designs a kind of RFID of having function can conveniently help people's keeping valuables.

Summary of the invention

The utility model technical matters to be solved is to the deficiency of above-mentioned background technology, and a kind of RFID wrist-watch is provided.

The utility model adopts following technical scheme for realizing the foregoing invention purpose:

A kind of RFID wrist-watch comprises watchband, table body, is built in wrist-watch substrate circuit, RFID switch, RFID inductor, controller, warning circuit in the table body; Wherein: said RFID switch places the table body side surface, is used to control the switch of RFID inductor; Said controller, warning circuit are arranged in the wrist-watch substrate circuit, and said RFID inductor is connected with controller through communication interface;

The radio-frequency module of said RFID inductor is sent to controller with the electronic labeling information that scans in real time and is stored in the controller, and controller indication warning circuit when the electronic tag of storage exceeds distance of reaction is reported to the police.

In the said RFID wrist-watch, warning circuit is the circuit of jingle bell frequency adjustable, when different article exceed RFID inductor distance of reaction, sends the different alarm tone of frequency.

In the said RFID wrist-watch, controller is ARM 7 TDMI chips.

In the said RFID wrist-watch, the wrist-watch substrate circuit comprises crystal oscillating circuit, reset circuit, the circuit that gives the correct time, liquid crystal display circuit, time adjusting circuit, date adjustment circuit.

The utility model adopts technique scheme, has following beneficial effect: the RFID inductor is gathered on the wrist-watch, and compact volume and convenience is assisted the convenient keeping of people valuables.

Embodiment

Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model:

RFID wrist-watch main structure chart as shown in Figure 1, it comprises table body 1, watchband 2, display screen 3, RFID inductor 4.The wrist-watch machine plate that patent of the present invention designed is built in the middle of the table body, has kept that electronic watch shows date, time and adjustment function.Can manifest current real-time time and current date through display screen.If the user needs speech chronopher, can press the button that gives the correct time, realize speech chronopher.Integrated the RFID inductor in the wrist-watch machine plate simultaneously.4 places in wrist-watch position such as Fig. 1 see through and read RFID label on every side, whether break away from read range to judge the thing under this label, and then the signal that sounds a warning.

Wrist-watch machine plate circuit as shown in Figure 2 comprises controller 5, liquid crystal display circuit 6, time adjusting circuit 7, date adjustment circuit 8, crystal oscillating circuit 9, reset circuit 10, the circuit 11 that gives the correct time, RFID radio-frequency module 12 and emitting antenna 13, warning circuit 21.

Wherein, controller 5 adopts ARM 7 TDMI.Chromatic liquid crystal screen is adopted in liquid crystal display 6.The circuit that gives the correct time is made up of driving circuit, loudspeaker and speech chip.

RFID inductor 12 is transmitted and receive data, is radiate with the electromagnetic wave form through emitting antenna 13 by controller control radio-frequency module.Emitting antenna 13 adopts the printed circuit board antenna.

Warning circuit is a Frequency Adjustable generation circuit, and the occurrence frequency according to the different adjustment warning circuit of the valuable degree of article plays warning function.

Electronic tag shown in Figure 3 comprises receiving antenna 14, rectification circuit 15, mu balanced circuit 16, first data demodulation circuit 17, second data modulation circuitry 18, electronic tag control controller 19 and eeprom chip 20.Electronic tag end antenna adopts the printed circuit board antenna.
