Abstract
The invention discloses an alarming device for preventing children from losing, comprising two parts, namely a signal transmitting unit and a signal receiving and processing unit, wherein the signal transmitting unit mainly comprises a signal transmitter and a modulating panel which are connected; and the signal receiving and processing unit mainly comprises a single chip microcomputer which is connected with a signal receiver, a control panel and an alarming device simultaneously. According to the alarming device, the receiving distance is controlled by presetting the transmitting intensity of signals on the control panel and the modulating panel according to the need of the control range for the children; if the activity range of the children exceeds the set value, the signals received by the single chip microcomputer become weak or disappear, the alarming device can transmit corresponding reminding signals, and then parents can take measures in time to find the children.
Description
Technical field
The invention belongs to child's safety article technical field, be specifically related to the warning device that a kind of juvenile of prevention loses.
Background technology
Present public arena flow of the people is big, and many father and mother can carry small children out to make a visit to and play, and perhaps run errands; Because child's curiosity; What the busy meeting of child can't help runs chaotically, and also will worry about child's active situation when the adult goes out constantly, influences adult's energy; Sometimes the problem that also causes child to lose is given the family that has even is caused lifelong regretting deeply and misery.
Summary of the invention
The purpose of this invention is to provide the warning device that a kind of juvenile of prevention loses, after having solved existing children ' s activity scope and exceeding adult's sight line, the adult can't in time know, the problem that causes child to lose.
The technical scheme that the present invention adopted is; The warning device that a kind of juvenile of prevention loses; Comprise signal transmitter unit and signal processing unit two parts; The signal transmitter unit comprises that mainly signal projector and modulation panel connect to form, and signal processing unit mainly comprises single-chip microcomputer, and single-chip microcomputer is connected with signal receiver, control panel, warning device simultaneously.
The invention has the beneficial effects as follows that after child's scope of activities exceeded adult's sight line certain distance, device sent alerting signal, the adult will in time know and find child, prevents that the problem that child loses from taking place.
Description of drawings
Fig. 1 is the modular structure synoptic diagram of apparatus of the present invention.
Among the figure, 1. signal transmitter unit, 2. signal projector, 3. modulation panel, 4. signal receiver, 5. control panel, 6. single-chip microcomputer, 7. warning device, 8. signal processing unit.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
As shown in Figure 1; The structure of the warning device that prevention juvenile of the present invention loses is; Comprise signal transmitter unit 1 and signal processing unit 8 two parts; Signal transmitter unit 1 comprises that mainly signal projector 2 and modulation panel 3 connect to form, and signal processing unit 8 mainly comprises single-chip microcomputer 6, and single-chip microcomputer 6 is connected with signal receiver 4, control panel 5, warning device 7 simultaneously.For the ease of carrying, signal transmitter unit 1 all uses dry cell with signal processing unit 8 two-part power supplies, conveniently uses and changes.
The warning device that prevention juvenile of the present invention loses; According to the needs to child's range of control, the intensity of setting signal emission on control panel 5 and modulation panel 3 is in advance controlled the distance of reception; If child's scope of activities exceeds setting value; Signal weaker or disappearance that single-chip microcomputer receives, warning device will send corresponding alerting signal, and the adult just can in time take measures to find child.
