Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, clear, complete description is carried out to the technical solution of the utility model below.

As Figure 1-Figure 4, a kind of Intelligent bracelet, comprise bracelet ring body 1, LCDs 2, button 3, single-chip microcomputer main control chip 7, GPS positioning chip 8, GSM/GPRS communication chip 9 and rechargeable battery 13, described LCDs 2 and button 3 are installed on described bracelet ring body 1, described single-chip microcomputer main control chip 7, GPS positioning chip 8, GSM/GPRS communication chip 9 and rechargeable battery 13 are all arranged in described bracelet ring body 1, rechargeable battery 13 by power line 11 respectively with single-chip microcomputer main control chip 7, GPS positioning chip 8 is connected with GSM/GPRS communication chip 9, GPS positioning chip 8 is connected with single-chip microcomputer main control chip 7 respectively by different serial ports with GSM/GPRS communication chip 9, bracelet ring body 1 is provided with the charging socket 12 corresponding to rechargeable battery.Also be provided with PCB 10 in described bracelet ring body 1, described single-chip microcomputer main control chip 7, GPS positioning chip 8 and GSM/GPRS communication chip 9 are all arranged in described PCB 10

Because the utility model arranges the GPS positioning chip 8 with locating information in bracelet ring body 1, GSM/GPRS communication chip 9 has architecture function simultaneously, take GPS/TDOA integrated navigation and location algorithm, realize round-the-clock comprehensive accurate location in real time, guardian is by the position of mobile phone A PP real-time tracking wearer.

In addition, described bracelet ring body is provided with 4 buttons, the first button 3 can be used for arranging displaying time, date and week information on LCDs 2; Second button 4 can be used for arranging the real-time positioning information that bracelet checked by LCDs 3, and uploads onto the server; 3rd button 5 can be used for sending SOS SOS to guardian's mobile phone; 4th button 6 checks the tutorial information table of wearer for arranging LCDs 3, comprise guardian's name, contact method and home location, facilitate police or other people get in touch with guardian in time, simultaneously, as long as length more than 5s, can realize distress call SOS by arbitrary button.

Be illustrated in figure 5 the operation principle block diagram of the utility model bracelet.System take single-chip microcomputer as main control module, by information such as GPS module Real-time Collection current location, speed, directions, and be supplied to single-chip microcomputer by serial ports, the TDOA locator data of acquisition is also transferred to single-chip microcomputer by communication module simultaneously, two data are merged by GPS/TDOA combinational algorithm by single-chip microcomputer, obtain accurate bracelet position, after analyzing and processing by deposit data in memory, conveniently call.Communication module carries out information interaction by base station and user under the control of single-chip microcomputer, and user can the position of real time inspection wearer by mobile phone A PP.Arrange the display information of Single-chip Controlling display module by key-press module, power module is responsible for powering to whole system.In whole service process, single chip control module is responsible for the process of data, and simultaneously the also work of modules in control and management system, makes them cooperatively interact, realize the function of bracelet.

As shown in Figure 6, the GPS/TDOA integrated navigation and location mode that the utility model adopts, when gps signal and TDOA signal are all stablized effective, the difference of the positional information that the positional information export TDOA and GPS export is as measuring value, carry out optimum Kalman filtering combination, filter result exports as navigation data.When gps signal lost efficacy, time as intensive in city high rise building or indoor, gps signal is subject to block, be then converted to TDOA location; When TDOA Signal Fail, as spacious isolated area, base station number is less, be then converted to GPS location.By the mutual coordination of two kinds of locate modes, all can cannot provide separately when precise location information when two kinds of locate modes and still obtain locator data comparatively accurately, substantially increase the scope of application of bracelet.

As shown in Figure 7, the GPS/TDOA integrated navigation and location precision simulation figure of the utility model employing.When TDOA location and GPS locate available, carry out Kalman filtering.As can be seen from simulation curve, GPS/TDOA integrated navigation system can improve the positioning precision of system to a certain extent.

The algorithm that the utility model adopts is existing algorithm; based on the detailed description of the invention in the utility model; other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope that the utility model is protected.
