Embodiment

As shown in Figure 1; The anti-system of wandering away of a kind of children of the utility model; Comprise that children hold equipment and father and mother to hold equipment; Described father and mother's end equipment comprises first CPU, the first remote-wireless transport module, a GPS locating module, the first speech talkback module, near radio receiver module, and the signal output part of first CPU is connected with display screen, and the signal output part of first CPU is connected with alarm module; Described children's end equipment comprises second CPU, the second remote-wireless transport module, the 2nd GPS locating module, the second speech talkback module, near radio transmitter module; The signal output part of second CPU also is connected with alarm module, and the signal input part of second CPU also is connected with the key circuit of seeking help.First CPU and second CPU are carried out radio communication through the first remote-wireless transport module and the second remote-wireless transport module respectively; First CPU and second CPU are also carried out short haul connection through near radio receiver module and near radio transmitter module.

As shown in Figure 2; Second central processing unit CPU 2 (ATMEGA64) is connected with crystal oscillating circuit (crystal oscillator OSC1, electric capacity OSCC1, OSCC2 constitute), reset circuit (interface PROD1 and resistance R ST); The signal input part of second central processing unit CPU 1 is connected with the key circuit of seeking help; The key circuit of seeking help comprises the button SOSS1 that seeks help, resistance SOSR1; The end of button SOSS1 of seeking help is connected with the pin 15 of second central processing unit CPU 1, and when pressing when seeking help button SOSS1, the control second remote-wireless transport module sent help signal to father and mother's end equipment after second central processing unit CPU 1 received help signal.Resistance LR1 and light emitting diode COMD constitute the working indicating of the second remote-wireless transport module.

As shown in Figure 3; The second remote-wireless transport module IC3 (super low-power consumption micropower wireless data transmission module APC240) is connected with second central processing unit CPU 2, and the second central processing unit CPU 2 directly control second remote-wireless transport module IC3 transmits and receive data.

As shown in Figure 4; The 2nd GPS locating module IC4 is connected with second central processing unit CPU 2; The 2nd GPS locating module IC4 receives the information of self-position; Sending to second central processing unit CPU, 2, the second central processing unit CPUs 2 sends to father and mother through the second remote-wireless transport module with positional information and holds equipment.

The Navsat of GPS positioning system is operated in 1575.42MHz and 1227.6MHz under 2 kinds of frequencies; The receiver that we use always a frequency of utilization is the signal of 1575.42MHz, and this ripple is high frequency waves, and wavelength ratio is shorter; Diffracting power is poor; So when the GPS receiver is blocked by tall and big objects such as buildingss, just do not receive satellite-signal, also just can not position, these zones promptly are GPS location " blind area ".For can be in the emporium, supermarket and the bigger GPS blind area of the such stream of people in station carry out distance alarm; Added the short-distance alarm function in the system of should anti-wandering away; Like Fig. 5, shown in Figure 6; Be made up of near radio transmitter module IC1 and near radio receiver module REC, wherein near radio transmitter module IC1 is installed in children's end, and near radio receiver module REC is installed in father and mother's end.When the distance between near radio receiver module and the near radio transmitter module surpassed certain distance, father and mother held first CPU of equipment to report to the police with regard to control warning module, send chimes of doom.

As shown in Figure 7; The second speech talkback module is made up of intercommunication chip IC 2, loudspeaker SPK1, button SPS1; The second speech talkback module can initiatively be talked, and uses for ease, in this system, has chosen main communication channel; Adjust after the volume just unsettledly, simplify the operation steps in using corresponding pin." PTT " pin both had been connected to button SPS1; Also meet a pull-up resistor SPKR1; Pull-up resistor SPKR1 draws high " PTT " pin level when not conversing, and drags down " PTT " pin by second central processing unit CPU, 2 output one low levels or the SPS1 that pushes button during conversation.On the power supply of intercommunication chip IC 2, add a diode SPKD1 (IN5819); Utilize these characteristics of pressure drop of diode SPKD1 that this point voltage is carried out clamper; I.e. when the second speech talkback module is pulled down to 3.0V with voltage (being lower than 3.0V can not work); The DVCC that can also guarantee circuit system guarantee second central processing unit CPU, 2 operate as normal, and both ends of power adds anti-interference capacitor SPEAKC1 at 3.3V.Light emitting diode SPD1 constitutes the work indication of the second speech talkback module.

As shown in Figure 8; First central processing unit CPU 1 (ATMEGA64) is connected with crystal oscillating circuit (crystal oscillator OSC, capacitor C X1, CX2 constitute), reset circuit (interface PROD1 and resistance PRO_R1 constitute), and the signal output part of first central processing unit CPU 1 is connected with display screen OLED; The signal output part of first CPU also is connected with power work indicating circuit that is made up of resistance LR1 and light emitting diode COMD1 and the second remote-wireless transport module working indicating that is made up of resistance LR2 and light emitting diode COMD2.

As shown in Figure 9; The first remote-wireless transport module WL_M (super low-power consumption micropower wireless data transmission module APC240) is connected with first central processing unit CPU 1, and the first central processing unit CPU 1 directly control first remote-wireless transport module WL_M transmits and receive data.

Shown in figure 10, a GPS locating module GPS_M is connected with first central processing unit CPU 1, receives the information of self-position, sends to first central processing unit CPU 1.

Shown in figure 11; The first speech talkback module is made up of intercommunication chip SPK_M (MT-WK-182), loudspeaker LS1, button SPK_S1; On the power supply of intercommunication chip SPK_M, add a diode SPD2 (IN5819); Utilize these characteristics of pressure drop of diode SPKD1 that this point voltage is carried out clamper, i.e. when the first speech talkback module is pulled down to 3.0V with voltage (being lower than 3.0V can not work), the DVCC that can also guarantee circuit system is at 3.3V; Guarantee first central processing unit CPU, 2 operate as normal, and both ends of power adds anti-interference capacitor SPKC.Light emitting diode SPD1 constitutes the work indication of the first speech talkback module.

It is the composite aircraft form that the children of native system hold equipment and father and mother's end equipment, and wherein children's end is handset, and father and mother's end is machine tool, and the major function of realization has:

1. short-distance alarm function

Can utilize the power of the wireless signal of near radio receiver module and near radio transmitter module to carry out the short distance warning between the composite aircraft; When the short distance warning function of composite aircraft is all opened; Handset will regularly be sent wireless signal to machine tool; Machine tool is judged handset and own position distance according to the signal that receives is strong and weak, when signal intensity during less than pre-set value, produces alarm on machine tool and the handset simultaneously; On father and mother's end equipment, eject child's current position information simultaneously automatically.

2. child's help function initiatively

When child finds to can not find father and mother; And in the time of not exceeding the safe distance of setting; Can press the button of seeking help on the handset; Send the latitude and longitude information of self to machine tool together with a help information through wireless transport module, machine tool will be reported to the police after receiving this information at once, and demonstrate the child position of oneself relatively.

3. speech talkback function

When between father and mother and the child when out of touch, can carry out speech talkback through built-in speech talkback module between the composite aircraft, make father and mother find child more fast.
