Abstract
The utility model relates to a kind of preventing child losing device, comprises control device, emitter; Described control device is connected by wireless signal with emitter; The receiving circuit, frequency controller, the loudspeaker that connect successively is provided with in described control device; Radiating circuit is provided with in described emitter; Described receiving circuit differentiates the distance between control device and emitter by the wireless signal that radiating circuit sends, thus makes frequency controller control loudspeaker send the sound of different frequency; The utility model sends the sound of different frequency by loudspeaker, makes father and mother can find child very soon, ensure that the safety of child, and structure is simple, easy to use.
Description
Technical field
The utility model relates to daily life field, refers in particular to a kind of preventing child losing device.
Background technology
At present, the report that online and TV has many children to lose, the generation majority of these situations is because the head of a family is thoughtless or general idea causes;
A kind of Low emissivity children lose resisting device is disclosed in prior art 201320401217.4, comprise Digiplex and steady arm, described Digiplex is got in touch with by transmitting wireless connections signal and steady arm, and described Digiplex comprises telepilot central processing unit, wireless transmitter module, button, power supply of remote controller administrative unit and power supply of remote controller; Described steady arm comprises wireless receiving module, steady arm Power Management Unit, steady arm power supply, retainer central processor, GSM/GPRS module and GPS module; Because child's height is lower, easily blocked by large-sized object when going out, cause father and mother cannot see, and prior art is when distance very closely uses, GPS module cannot be located accurately, can not father and mother be made to find child at once, easily allow child go astray from the group, for this reason, we have developed a kind of preventing child losing device, child can be found very soon by the frequency of sound, ensure that the safety of child.
Utility model content
The utility model object provides a kind of preventing child losing device to overcome the deficiencies in the prior art, can find child very soon, ensure that the safety of child by the frequency of sound.
For achieving the above object, the technical solution adopted in the utility model is: a kind of preventing child losing device, comprises control device, emitter; Described control device is connected by wireless signal with emitter; The receiving circuit, frequency controller, the loudspeaker that connect successively is provided with in described control device; Radiating circuit is provided with in described emitter; Described receiving circuit differentiates the distance between control device and emitter by the wireless signal that radiating circuit sends, thus makes frequency controller control loudspeaker send the sound of different frequency.
Preferably, switch and button is also provided with in described control device; Described switch is for controlling the connection of receiving circuit and radiating circuit; Described button is used for the connection of controlled frequency controller and loudspeaker.
Preferably, also clock circuit is provided with in described emitter.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Preventing child losing device described in the utility model sends the sound of different frequency by loudspeaker, make father and mother can find child very soon, ensure that the safety of child, and structure is simple, easy to use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the frame diagram of preventing child losing device described in the utility model;
Wherein: 1, control device; 11, switch; 12, receiving circuit; 13, frequency controller; 14, button; 15, loudspeaker; 2, emitter; 21, radiating circuit; 22, clock circuit.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is preventing child losing device described in the utility model, comprises control device 1, emitter 2; Described control device 1 is connected by wireless signal with emitter 2; The switch 11, receiving circuit 12, frequency controller 13, button 14, the loudspeaker 15 that connect successively is provided with in described control device 1; Radiating circuit 21, clock circuit 22 is provided with in described emitter 2; Described switch 11, for controlling receiving circuit 12 and the connection of radiating circuit 21, judges the distance between control device 1 and emitter 2, thus makes frequency controller 13 control loudspeaker 15 send the sound of different frequency; Described button 14 is connected with loudspeaker 15 for controlled frequency controller 13; Described clock circuit 22 can check the time to child.
During use: emitter 2 can be made wrist-watch and treat in child's wrist, and control device 1 has father and mother to carry.
When father and mother with child go out go window-shopping or play time, first open switch 11, now receiving circuit 12 just can with radiating circuit 21 wireless connections; When the distance of father and mother and child exceedes setpoint distance (as 5 meters), receiving circuit 12 is reported to the police by frequency controller 13 control loudspeaker 15 automatically, and now father and mother can press the button the 14 sound frequency searching children sent by loudspeaker 15; When father and mother and the sound frequency that sends of the nearlyer loudspeaker 15 of child's distance lower, then the sound frequency that sends of loudspeaker 15 is higher on the contrary.
When the distance of father and mother and child does not exceed setpoint distance, and father and mother cannot see child when needing to find, and also can press the button 14 sound frequencies sent by loudspeaker 15 and find children; When father and mother and the sound frequency that sends of the nearlyer loudspeaker 15 of child's distance lower, then the sound frequency that sends of loudspeaker 15 is higher on the contrary.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Preventing child losing device described in the utility model sends the sound of different frequency by loudspeaker, make father and mother can find child very soon, ensure that the safety of child, and structure is simple, easy to use.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
