Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0015] The basic principle of GPS positioning is to use the method of spatial distance resection to determine the position of the point to be measured according to the instantaneous position of the high-speed moving satellite as the known starting data. Such as figure 1 As shown, assuming that a GPS receiver is placed on the ground to be measured at time t, the time Δt for the GPS signal to reach the receiver can be measured, coupled with other data such as the satellite ephemeris received by the receiver, it can be determined as figure 1 of the four equations. In the four equations, the coordinates x, y, z and Vto of the point to be measured are unknown parameters, where di=cΔti (i=1, 2, 3, 4). di(i=1, 2, 3, 4) are the distances between satellite 1, satellite 2, satellite 3, satellite 4 and the receiver respectively. Δti (i=1, 2, 3, 4) is the time elapsed f...

Abstract

The invention relates to a child garment accessory implanted with a GPS (global positioning system) positioning module, in particular to a child missing preventive garment accessory on the basis of GPS positioning and belongs to the technical field of clothes design. The technical scheme includes that a GPS missing preventive module implanted in the child garment is not fixed, and continuous practicality of the GPS positioning module and feasibility of the garment during washing are improved. The accessory combined with the GPS positioning module is a plush cartoon accessory, on one hand, the GPS positioning module has no hurt to tender skin of a child, on the other hand, the GPS positioning module cannot be damaged initiatively by the child and found by lawbreakers. The GPS missing preventive module implanted in the child garment is not fixed, and various garments can be provided with a GPS positioning function when garment accessories are combined with the GPS positioning module; the garment accessories can be detached during washing of the garments, practicality is improved and the child missing preventive garment accessory is compact in structure, wide in application range, convenient to detach, safe and reliable.

Description

technical field [0001] The invention relates to children's clothing accessories implanted with a GPS positioning module, in particular to children's lost-prevention clothing accessories based on GPS positioning. Background technique [0002] This year, although the police have intensified their efforts to crack down on child trafficking, there are still criminals taking advantage of the ignorance of young children and the negligence of adults to abduct and traffic children to remote mountain villages. In 2011, the police in Shangluo City successfully detected a kidnapping case. A Luonan boy who was trafficked 22 years ago was reunited with his family. As of the end of August, the police in Shangluo City had cracked 18 cases of child trafficking, rescued 20 trafficked child women, cracked down on 10 suspects, and successfully repatriated 1 foreign woman. On the afternoon of September 7, nine abducted children met their biological parents in Quanzhou City, Fujian Province. W...
