Research on image acquisition and wireless transmission based on STM32

This paper proposed an embedded system to acquire and storage images periodically based on STM32 and transmit images with GPRS to monitoring center. Monitoring center can also send command to acquisition terminals over GPRS. Acquisition terminals are based on STM32 characterized by low energy consumption and high performance. Experiments showed acquisition terminals were stable and reliable in acquisition and image storage, capable of controlling different acquisition angels and uploading images to monitor center. The packet loss probability is less than 10% and average time delay is 2 seconds.
