Laser Monitoring System for Crossing Border Based on the Short Message Service
Zhu Wen-jin, Zhou Dao-qing, Zhou Lu-jun · Journal of Physics Conference Series · 2016
A warning system applied to long-distance crossing-border monitoring by the technology SMS and IR(infrared) laser was introduced. Master station, which was based on PC and module TC35i, would transmit or receive short message by COM communication. Monitoring station watched the forbidden zone produced by an IR warning apparatus. CMOS chip AT89C52 incepted the warning information, and transmitted out a warning message by module TC35i. Circumstance of hardware and software was provided and programming was described also. The system overcame the shortages and restrictions on conventional communication and monitoring system.
