Abstract
The utility model relates to a device for preventing children from getting lost, which is composed of a crash locator beacon machine (1), a flexible band (3), a monitor machine (2), etc., wherein, the crash locator beacon machine (1) is hung over the children's neck through the flexible band (3), and the monitor machine (2) is arranged on a guardian's body. The utility model can realize the warning and the overrun warning within certain meter range, can conduct the direction finding within certain meter range when the parents discover the children losing, helps parents find exactly in time the own children, effectively protects the children's safety, and gets rid of many parents' secret worry.
Description
Affiliated technical field
The utility model belongs to children's anti-loss device technical field.
Background technology
Children's anti-loss device is being called for a long time in market, but does not see similar products up to now yet, and reason is that children's anti-loss device with practical value must have both short-distance alarm, target-seeking at a distance, volume is small and exquisite, and is in light weight, save electric energy, comprehensive advantage such as price is low.
Summary of the invention
The utility model provides a kind of can guard against overload alarm several meters scopes; To give children's children's anti-loss device and volume for change little in case children loss can carry out the target-seeking help of the direction finding head of a family hundreds of meters scopes, saves electric energy.The technical scheme that its technical matters that solves the utility model adopts is: Radio Beacon (1) hangs on children's neck with soft band (3) or lies on the waist, and monitoring equipment (2) is arranged on one's body the guardian; Radio Beacon (1) is made of transmitting set (7), wireless receiver (8), and monitoring equipment (2) is made of electrometer of field strength (6), wireless receiver (9), transmitting set (10), antenna (5); Wherein antenna (5) is a parabola antenna.
The beneficial effects of the utility model are: when children are in monitoring number rice scope when movable not sounding of watch-dog, in case the watch-dog that transfinites just sends chimes of doom; If exceeding the visual field, children can carry out wireless direction-finding judgement children loss direction so that give the lost children rapidly for change.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the novel structural drawing of this reality.
Fig. 2 is the electrical schematic diagram of Radio Beacon (1).
Fig. 3 is the schematic diagram of monitoring equipment (2).
Among the figure: 1 Radio Beacon, 2 monitoring equipments, 3 soft bands, 4 loudspeaker, 5 antennas, 6 electrometer of field strength, 7 transmitting sets, 8 wireless receivers, 9 transmitting sets, 10 wireless receivers, 11 switches.
Among Fig. 2, when pressing switch TK circuit energized, this moment IC
1Vibration, 3 pin are intermittently exported noble potential, pass through D
1Give transmitting set (7) power supply.Because the operating voltage of transmitter (7) is because of D
2, R
3Voltage stabilizing is in being lower than under the supply voltage, so work in under-voltage weak oscillatory regime, this moment, operating distance was only several meters.
If wireless receiver (8) is received the wireless signal that monitoring equipment (2) sends and will be exported a noble potential to BG
1Make IC
2So upset is IC
23 pin output noble potential full-amount supply voltage is provided for transmitting set (7), make it work in the hard oscillation state, operating distance rises to hundreds of rice, provides enough signal sources for monitoring equipment carries out wireless direction-finding.
Fig. 3 is by electrometer of field strength voltage table (6), wireless receiver (9), transmitting set (10) bistable circuit IC
1Etc. formation.The radio signal that receives Radio Beacon (1) when wireless receiver (9) will be from 3 ends output noble potential, through BG
1Shaping makes IC
12 pin noble potentials, so 3 pin electronegative potentials are voice IC
2No-output, loudspeaker (4) are noiseless.This state represents children still in the security area.
If children have left the warning region of several meters scopes, wireless receiver (9) can not receive the Radio Beacon wireless signal, and its 3 end will be exported electronegative potential, IC
1Also electronegative potential of 2 pin, so IC
1Upset, 3 pin output noble potential voice sheet IC
2Power work, output audio alert signal, loudspeaker (4) send chimes of doom and remind the guardian, children are not at one's side.
If confirm that children are missing, can press the teleswitch K (11) of watch-dog (2) so transmitting set (10) is launched the wireless remote control signal, make the IC of Radio Beacon (1)
2Upset enters sufficient pressure oscillatory regime, and launching can be hundreds of meters scope valid wireless beacon signal.
Rotate antenna (5) direction of monitoring equipment (2) this moment, observe the indication numerical value of electrometer of field strength (6), when field intensity voltmeter indication full-scale reading, parabola antenna the rim of a bowl right direction be exactly the children loss direction, seek this direction and move ahead and can find the children that lose.Electrometer of field strength (6) is a D.C. voltmeter, and the high frequency radio field intensity that its indication numerical value and wireless receiver (9) receive is proportional.
Claims (2)
1, a kind of children's anti-loss device is made up of Radio Beacon (1), soft band (3), loudspeaker parts such as (4), it is characterized in that Radio Beacon (1) is furnished with soft band (3), and soft band (3) is hung on children's neck or lies on the waist, and monitoring equipment (2) is arranged on one's body the guardian; Radio Beacon (1) is by transmitting set (7), and wireless receiver (8) constitutes, and monitoring equipment (2) is made of electrometer of field strength (6), antenna (5), wireless receiver (9), transmitting set (10).
2, the described children's anti-loss device of claim 1 is characterized in that antenna (5) is a parabola antenna.
