Description

Electronic equipment finder for children

Technical Field

The utility model relates to an intelligent equipment especially relates to a children's electronic equipment finder.

Background

At present, related electronic products of children are more and more, such as telephone watches and electronic playing devices, which are articles frequently used by children, but due to the fact that the articles are single in function and powered by batteries, electronic equipment often falls to a hidden position in a power-off state due to carelessness of the children, and therefore cannot be accurately found.

Disclosure of Invention

The utility model aims at: the electronic equipment finder for children is capable of effectively finding the electronic equipment when the electronic equipment is turned off.

In order to realize the purpose, the technical scheme of the utility model is that:

a children electronic equipment finder comprises a hanging ring piece, a circuit wafer, a micro control chip, a radio frequency trigger circuit, a patch buzzer and a battery wafer, wherein the circuit wafer is packaged inside the hanging ring piece, the hanging ring is arranged on the hanging ring, the micro control chip, the radio frequency trigger circuit, the patch buzzer and the battery wafer are welded on the circuit wafer, the radio frequency trigger circuit is connected to an interrupt input interface of the micro control chip, the patch buzzer is connected to an IO interface of the micro control chip, and the battery wafer is connected to a power supply end of the circuit wafer.

In the electronic device finder for children, the micro control chip adopts an MCU chip ATmega8 with a standby function.

In the above finder for electronic equipment for children, the radio frequency trigger circuit adopts the wireless switch state trigger chip JZ480 to form a radio frequency circuit.

The utility model discloses the low power dissipation can long-term operation at standby state to can start bee calling organ and send and retrieve after receiving wireless triggering signal and remind sound signal.

Drawings

Fig. 1 is a schematic structural diagram of the electronic device finder for children according to the present invention.

Fig. 2 is a circuit diagram of the electronic device finder for children according to the present invention.

Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

Referring to fig. 1 and 2, a finder for electronic devices for children includes a ring plate 1, a circuit plate 2, a micro control chip 3, a radio frequency trigger circuit 4, a patch buzzer 5, and a battery plate 6, where the circuit plate 2 is packaged inside the ring plate 1, the ring plate 1 is provided with a ring 7, the micro control chip 3, the radio frequency trigger circuit 4, the patch buzzer 5, and the battery plate 6 are all welded on the circuit plate 2, the radio frequency trigger circuit 4 is connected to an interrupt input interface of the micro control chip 3, the patch buzzer 5 is connected to an IO interface of the micro control chip 3, and the battery plate 6 is connected to a power supply terminal of the circuit plate 2.

The micro control chip 3 adopts an MCU chip ATmega8 with standby function. The micro control chip 3 is in a standby state in a normal state, so that the power consumption is low, the battery power can be consumed to the minimum extent, and the working state of the micro control chip 3 is triggered by an interrupt signal.

The radio frequency trigger circuit 4 adopts a wireless switch state trigger chip JZ480 to form a radio frequency circuit. The wireless switch state trigger chip JZ480 can convert an externally received ASK/OOK modulation signal into a switching value level signal and transmit the switching value level signal to an interrupt interface of the micro control chip 3, and the radio frequency trigger circuit 4 adopts a chip for converting a wireless signal into a switching signal, so that the power consumption of the chip can be greatly reduced compared with that of a chip for wireless data transmission, and the service life of a battery can be prolonged.

The utility model discloses mainly used children's electronic product's the finding back, consequently, require longer operating duration to in the children's electronic product of finding back shutdown state, whole device is installed on children's electronic product through link 7 on the link piece 1, and micro control chip 3 and radio frequency trigger circuit 4 all are in standby state under the normal condition, and the module all is in dormant state on two parts this moment, and the consumption of whole part this moment is minimum.

If the electronic product for children equipped with the device is turned off and the falling position cannot be determined, a wireless radio frequency signal can be sent indoors through the ASK/OOK emission controller, a radio frequency receiving end of the radio frequency trigger circuit 4 generates a trigger signal due to receiving an ASK/OOK modulation signal, so that the radio frequency trigger circuit 4 is triggered to convert the modulation signal into a switching value signal and transmit the switching value signal to an interrupt interface of the micro control chip 3, the micro control chip 3 triggers and activates the micro control chip 3 to be in a running state due to receiving a rising edge trigger signal of a switching level signal, at the moment, the micro control chip 3 immediately controls the patch buzzer 5 to send out 10-time interval sounding signals through the IO interface, so that a person is reminded of the current position of the electronic product through sound, when the micro control chip 3 controls the patch buzzer 5 to send out sound, the standby state is immediately entered by an internal program in order to save power consumption. The radio frequency trigger circuit 4 also enters a standby state after not receiving the ASK/OOK modulated radio frequency signal within a certain time.

ASK OOK transmission controller be with the utility model discloses the supporting ASK OOK modulation signal transmitter of radio frequency signal, personnel can send corresponding ASK OOK modulation radio frequency signal so that trigger through the button on ASK OOK transmission controller the utility model discloses, ASK OOK transmission controller inside mainly constitute by wireless emission module WL102-331 and singlechip.

The utility model discloses except being used for the recovery of phone wrist-watch and broadcast electronic equipment, under the prerequisite that the cost can be accepted, also can be used for the recovery of other important article.
