When emergency response personnel is launched action in the strange environment of danger, need clear and definite own orientation of living in.And various danger in the foreign environment, disturbing factor is higher, needs reliable portable unit to determine own present position, thereby carries out action.In relatively large pick-up operation, directorate also need constantly clear and definite current affiliated personnel's accurate position, so that the unified command scheduling improves collaborative efficient.
Main individual locator meams is divided into following several according to principle at present: the GPS location; The mobile phone signal location; Monitoring camera location; Radio-frequency (RF) identification (RFID) location; Reckoning location etc.They respectively have superiority, and all exist defective separately again.The GPS location is present most popular locator meams.Its feature is that bearing accuracy is better, and usable range is wide, and the location is reliable.But shortcoming is to exist occlusion issue, and in built-up city, boulevard and indoor scenarios can't accurately be located.The mobile phone signal location can obtain the location under indoor situation, but precision is lower, more can't obtain elevation information.Monitoring camera location is a kind of location of passive type, and sporter itself can't directly be known locating information, and requires to arrange in advance in the environment camera supervisory system.Radio-frequency (RF) identification (RFID) technology mainly is fit to indoor environment, and need arrange a large amount of radio frequency positioning equipments in advance and could work, and cost is higher, and is still at the experimental stage.The reckoning location is according to the motion state measurement data, and adopts certain reckoning method to obtain sporter's track, has and implements easily lower-cost characteristics.But shortcoming has the error accumulation effect, calculates that for a long time error is bigger, causes overall accuracy on the low side.
Summary of the invention
That the purpose of this utility model is is not high at the prior art precision, poor reliability, technical matters that the facility cost is too high, and a kind of embedded individual locating device is provided, and this device is dexterous light, and precision is higher, good in anti-interference performance.
The purpose of this utility model is achieved through the following technical solutions: a kind of embedded individual locating device, and it comprises: core microprocessors, peripheral sensing circuit, output circuit and peripheral configuration circuit; Wherein, described peripheral sensing circuit, output circuit and peripheral configuration circuit link to each other with core microprocessors respectively, and described peripheral sensing circuit, output circuit link to each other with peripheral configuration circuit respectively.
Further, described peripheral configuration circuit mainly is made up of real time clock circuit, FLASH device, SDRAM device and electric power management circuit, described real time clock circuit, FLASH device, SDRAM device and electric power management circuit all link to each other with core microprocessors, and electric power management circuit also links to each other with output circuit with peripheral sensing circuit respectively.
Further, described peripheral sensing circuit comprises: acceleration transducer, gyroscope, height barometer, digital compass and GPS accept chip; Described acceleration transducer, gyroscope, high precision height barometer, digital compass are accepted chip with high-precision GPS and are all linked to each other with core microprocessors.
Further, described output circuit comprise RS232 serial line interface, LCD expansion mouthful and with the wireless transmit chip; Described RS232 serial line interface, LCD expansion mouth link to each other with core microprocessors respectively with the wireless transmit chip.
The beneficial effect of this novel practical is: the movement velocity of the utility model by the action detection personnel changes with direction, the distance and the target direction that go out to advance by the reckoning algorithm computation, and final definite operational staff's current location.It combines reckoning and GPS, and the shortcoming that can't locate when both having overcome the gps signal disappearance has improved the precision of reckoning again.This novel practical have strong interference immunity, reliability height, precision height, lightly easy, be easy to carry technical characterstic.
