The utility model content

are in order to solve the problem that existing model airplane is difficult to find after flight the time is fallen or lost; The utility model provides a kind of model airplane anti-loss device; The height and the latitude and longitude information of model airplane both can, model airplane be provided when flying; Also can, model airplane return the mobile phone of the latitude and longitude information of its position after losing to people; Thereby reach the purpose of seeking model airplane, cost is low, volume is little, in light weight, satisfies the requirement of model airplane to weight and volume fully.

the utility model solves the technical scheme that its technical matters adopted: this model airplane anti-loss device comprises STM32 processor, GPS module, gsm module and air pressure altitude module; The STM32 processor comprises serial ports 1, serial ports 2 and I2C interface, and gsm module is connected with the serial ports 1 of STM32 processor, and the GPS module is connected with the serial ports 2 of STM32 processor, and the barometer altitude module is connected with the I2C interface of STM32 processor; This model airplane anti-loss device is installed in the model airplane engine room inside, and the model airplane internal electric source is connected power supply with the STM32 processor.

described STM32 processor adopting STM32F103 series microprocessor; Be based on 32 standard risc processors of ARMv7-M architecture; Code efficiency is high, and frequency of operation is 72MHz, the Flash storer of built-in 128K byte and the SRAM of 20K byte.

described GPS module adopts the C3-370C module of Korea S JCOM company, adopts built-in aerial, cold start-up, the warm startup and three kinds of Starting mode of warm start is arranged, through serial ports 2 and STM32 processor swap data.

described gsm module adopts the SIM300 module; It is a three frequency band GSMs/GPRS module; Can work under in the world EGSM900MHz, DCM1800MHz and three kinds of frequencies of PCS1900MHz, nearly 10 GPRS multichannel types can be provided, support CS-1, CS-2, CS-3 and four kinds of GPRS encoding schemes of CS-4; Through serial ports 1 and STM32 processor swap data, and send and accept action through accepting mobile phone A T order.

described barometer altitude module adopts the BMP085 module, is the pressure transducer that precision is high, power consumption is low that can be applicable in the mobile device, is connected with the STM32 processor through the I2C interface.

When use ; After the model airplane internal electric source was given the power supply of STM32 processor, the model airplane anti-loss device was started working, and GPS module, gsm module and air pressure altitude module start; GPS module captured in real time latitude and longitude information also is sent to the STM32 processor; Barometer altitude module captured in real time elevation information also is sent to the STM32 processor, and the STM32 processor sends to latitude and longitude information and elevation information through gsm module on user's the mobile phone, when model airplane falls or loses in real time; The user can give model airplane for change fast according to the latitude and longitude information and the elevation information of mobile phone acceptance.
