2-b. goes reality using the speak () method of the TextToSpeech classes of Android when child leaves safety zone Existing voice broadcast and prompting function, voice warning child return to safety zone.

It is specific as follows for the distance for wherein judging child's deviating road:

Road is represented with a broken line, child can be modeled as coordinate points near roads activity can not to the distance of this broken line More than given threshold.Then be converted to a little to broken line ultimate range mathematical problem.Find nearest two of coordinate points Point, and ensure to be clipped in the middle of 2 points, obtain the height as beeline of the point to broken line of the triangle that these three points are surrounded.Tool Body algorithm is:First the key coordinate point on broken line is sorted according to longitude and latitude size, coordinate points is found and is all clipped in longitude respectively Two points and latitude between, then the institute of this four points and centre is a little compared with coordinate points obtain it is nearest with coordinate points Two points it is triangle, the height of the triangle finally tried to achieve is coordinate points to the beeline of broken line.Due to distance It is close, so the error that spherical coordinate is produced is ignored.Again the beeline for obtaining is carried out with the threshold value for pre-setting Relatively, if greater than threshold value, show that child present position has exceeded near roads safe distance, head of a family end will produce alarm signal Breath notifies father and mother.Coordinate points of Algorithm Analysis such as Fig. 6, the M point for current child, A, B, C, D and E ask the break on broken line respectively. First all breaks are sorted by size respectively according to longitude and latitude;Then point M minimum point D of latitude folded by 2 points are found out And E, point M longitude minimum point C and D folded by 2 points are found out in the same manner;Then two minimum point D of M to C, D and E distances are found out And E;The high MN as beelines of the point to broken line of the triangle surrounded by M, D and E is obtained finally.When the very long break of broken line very When many, this algorithm has higher efficiency.

Experimental situation

The real-time degree and precision of Kidsguard systems are tested under practical circumstances.Mobile phone used by the test of child end is Huawei H60-L02, running memory is 3G, and Android versions are 4.4.2, and mobile phone used by the test of head of a family end is MI 5, and running memory is 3G, Android version be 6.0, experiment place be Electronic University Of Science & Technology Of Hangzhou in the school.For real-time, by child end per three Second an information is sent to head of a family end, send 100 times, record and be sent to head of a family end from child end and receive location coordinate information Time, the receive information number of times in the different delays time under two kinds of networks, experimental result are as shown in table 1.

The table of degree experiment in real time of table 1

Receive time-consuming (s) 0-1 1-2 3-4 4-5 5-6 6-7 Mobile network 81 9 4 1 1 4 WiFi 86 7 1 0 0 6

Test result indicate that, the impact of mobile network and WiFi to real-time degree is basically identical, and WiFi is more stable to data transfer, but It is that packet loss is slightly larger than mobile network, has direct relation with the unimpeded rate of its network.It is basic at child end between head of a family's termination time receiving Send between the 0-3 seconds after data, real-time reception rate can meet the requirement of real-time 95% or so.Real-time with it is network-like State has very big relation, and different network states receives the time and real-time reception rate is also different.

The smart mobile phone positioning mode of main flow can be divided three classes at present:GPS location, architecture and mixed positioning.Root Three quasi-modes positioned according to mobile phone have carried out accuracy test experiment, test opening according to WiFi, mobile network and gps signal respectively Off status carrys out certainty of measurement.Look for 5 test points in campus at random, and the distance between test point is remote enough, then changes respectively Become the switch of WiFi, cellular network and GPS, then compare distance that map anchor point differed with practical test points as precision mistake Difference, averages as final precision, and the unit of precision is rice, and experimental result is as shown in table 2.

For the test of positioning precision, experimental result is represented, in the case where GPS is opened positioning precision in 2-10 rice, such as Fruit only uses WiFi or architecture, then position error will be very big, and error is likely to be breached more than hundred meters.So in order to chase after Seek higher precision, it should open GPS, the impact of WiFi and mobile network to precision is not especially big, and opening in GPS has network In the case of positioning precision up to 2-5 rice, in addition, the more positioning of the Wi-Fi hotspot of surrounding are more accurate.
