Embodiment Construction

[0033] See attached figure 1 , figure 2 , image 3 , Figure 5 , Figure 6 and Figure 7 The present invention is further described.

[0034] The present invention relates to a kind of mobile phone satellite communication method based on STM32 platform, is characterized in that, adopts STM32F427 chip platform design, comprises the following steps:

[0035] Step 1): The main body of the STM32F427 chip terminal is built. The main body of the STM32F427 chip terminal is integrated with a storage system connected to each other, a power network, an audio system, a core module, a BT / WIFI module, a button module, an LCD module, a SIM card module and level conversion module;

[0036] Step 2): The storage system is built. The storage system of the mobile phone is composed of two parts, the body memory and the external TF card. The body memory uses the MX69GL642E chip of MXIC Electronics. The MX69GL642E chip integrates NOR FLASH+ RAM for high-speed data transmission ;The external...

Abstract

The invention relates to a mobile phone satellite communication method based on an STM32 platform. An STM32F427 chip platform design is adopted, and an STM32F427 chip terminal body integrates a storage system, a power supply network, an audio system, a core module, a BT/WIFI module, a key module, an LCD module, an SIM card module and a level conversion module, which are in communication connectionwith each other; by adoption of the mobile phone satellite communication method, a complete set of digital signal processing instructions (DSP) and memory protection unit (MPU) is achieved, and the security of a mobile phone satellite communication application is improved; and a handheld terminal system based on the STM32 platform realizes the mobile phone communication function and supports thefree switching of the satellite communication mode and the traditional GSM mobile communication module.

Description

technical field [0001] The invention relates to the technical field of satellite communication production, in particular to a mobile phone satellite communication method based on an STM32 platform. Background technique [0002] The existing ground mobile communication infrastructure can already meet the communication services in the main land areas, but in the sea, air, land remote or extreme areas, especially in the face of special conditions such as emergency rescue and major natural disasters, and military applications Under such circumstances, the existing ground mobile communication facilities cannot implement good communication services. In this case, the satellite mobile communication system is still the only reliable choice. [0003] The satellite mobile communication system can provide users with mobile communication services such as voice, data, and short messages on a regional or even global scale by using mobile communication satellites in high and low orbits; sa...
