Design and implementation of embedded infrared prewarning system based on DM365 platform

摘要

In order to solve the security problems of university laboratories, a human body pyroelectric infrared induction circuit based on DM365 platform is proposed and applied in the prewarning security system design scheme. The design scheme is based on TMS320DM365 platform and embedded with ARM926HJ-S as kernel. In addition, chip BISS001 and its peripheral circuit is used to realize human body thermal source sensing and support Zigbee communication RF module. The system adopts Linux kernel and NET Framework4.0 development environment as well as uses C# as the development tool. Besides, the video control named CMTechVideo is used in the system to communicate with the video gateway. The system test results show that this system can control and collect the staff entrance/exit data in real-time mode correctly, and realize the function of taking photos and prewarning when the staff entrance/exit data are beyond the normal range; furthermore, this system possesses excellent extensibility.
