Abstract

The utility model relates to a Bluetooth finder which comprises a Bluetooth emitter and a Bluetooth receiver. The Bluetooth receiver comprises a Bluetooth receiving module, a master controller and an alarm circuit, the Bluetooth receiving module receives Bluetooth signals of the Bluetooth emitter and builds connection, the Bluetooth receiving module outputs signals to the master controller, and the master controller outputs signals to the alarm circuit. The Bluetooth finder can preset frequency range induction according to the emitter so as to achieve simultaneous searching of a plurality of articles, frequencies of emitters used by different user's products are different and have uniqueness, therefore other products cannot be interfered, and product working stability is guaranteed. The Bluetooth finder is small in volume, convenient, rapid and low in power consumption and radiation, sensing distance of the emitter and the receiver is within 10m, and the Bluetooth finder can meet requirements of most current houses for application.

Description

A kind of bluetooth article seeker

Technical field

The utility model relates to a kind of bluetooth article seeker.

Background technology

In the daily life, for some little article, such as key, wallet, glasses etc., people often very are not careful, and are dropped into conveniently the corner and then but can not find when usefulness.The author has an intimate knowledge to this, key especially, usually will with the time but always can not find and worry.To this, if we can invent a kind of small and exquisite hanging type or just mounted thing, can hang over easily or be attached on these little objects, when we need it but can't find for the moment, allow its active sounding shinny to we " report ", must allow this careless persons of the author convenient many.

We finish this research in conjunction with emerging Bluetooth technology thus, provide a low cost in conjunction with Bluetooth technology, and are convenient and swift, and the system of stability and high efficiency provides a low-power consumption to the user, low radiation, safe and convenient, the living environment of comfortable fashion.

Summary of the invention

The utility model is the problem of be difficult for seeking at ordinary times at one's side little article, has proposed a kind of bluetooth article seeker, is a article seeker that is convenient for carrying that utilizes the Bluetooth technology design, realizes that a plurality of article search simultaneously.

The technical solution of the utility model is: a kind of bluetooth article seeker, comprise bluetooth transmitters and Bluetooth Receiver, described Bluetooth Receiver comprises bluetooth receiver module, master controller and warning circuit, the bluetooth receiver module receives the Bluetooth signal of bluetooth transmitters and connects, bluetooth receiver module output signal is to master controller, and the master controller output signal is to warning circuit.

Described bluetooth receiver module and bluetooth transmitters all adopt the GC-02 Bluetooth chip.

It is acp chip that described master controller is selected the AT89C2051 single-chip microcomputer.

Described warning circuit is made of hummer and two complex pipes.

The beneficial effects of the utility model are: the utility model bluetooth article seeker, can be according to the induction of the predefined frequency range of transmitter, thus realize that a plurality of article search simultaneously; The frequency of the transmitter that the product of different user uses is different, has uniqueness, therefore can not cause interference to other other products, guarantees the stability of product work; Volume is little, convenient and swift, low-power consumption, low radiation, and the distance of reaction of transmitter and receiver can satisfy present most of dwelling house application in 10m.

Embodiment

Bluetooth article seeker structural representation block diagram as shown in Figure 1, bluetooth article seeker comprise that bluetooth transmitters 2 and Bluetooth Receiver 1 form, and Bluetooth Receiver 1 is comprised of bluetooth receiver module 10, master controller 11 and warning circuit 12.

Bluetooth transmitters circuit diagram as shown in Figure 2, bluetooth receiver module and bluetooth transmitters all adopt the GC-02 Bluetooth chip.

Bluetooth receiver module circuit diagram as shown in Figure 3, after bluetooth receiver module 10 in the Bluetooth Receiver 1 detected the Bluetooth signal of bluetooth transmitters 2 and connects, the P103 pin of GC-02 Bluetooth chip can be exported high level in the bluetooth receiver module, otherwise was low level.The signal that the P103 human hair combing waste goes out is sent into AT89C2051 single-chip microcomputer in the master controller, connects in order to judging whether.

Main controller circuit figure as shown in Figure 4, master controller is full of the parts such as electrification reset, crystal oscillation for the minimum system take the AT89C2051 single-chip microcomputer as core.When master controller detected the high-low level variation of AT89C2051 single-chip microcomputer P1.2 pin, the expression bluetooth received signal and sets up, and namely the user need to seek these article.Master controller 11 uses timer to produce pwm signal, drives AT89C2051 single-chip microcomputer P3.7 pin output alarm signal to warning circuit 12, finishes actuation of an alarm.

Warning circuit figure is made of hummer and two complex pipes as shown in Figure 5, makes circuit have two states.The pwm signal that the AT89C2051 single-chip microcomputer produces in the master controller 11 makes complex pipe alternately all be in amplification, hold mode, can well drive hummer, realizes warning function.

Booster circuit figure in the Bluetooth Receiver as shown in Figure 6 selects the SP6641B-5.0 chip of Sipex company, and the supply voltage of lithium battery is risen to 5V, is the power supply of master controller and warning circuit.Simultaneously, can select the 5V voltage of USB interface easily lithium battery to be charged.

The software C language programs, and bluetooth article seeker workflow diagram as shown in Figure 7.
