Existing monitoring system for the traditional personnel monitoring distance short, signal attenuation caused by severe personnel behavior characteristics identification of the disadvantages of low accuracy for frame structure, design a set of new personnel behavior monitoring system. Expounds the center control module, image acquisition module, GPRS module and rf module hardware design method, using ATM32F103C8T6 as center controller processing data, the use of COMS image sensor for personnel behavior image acquisition, image sensor to make use of programmable logic controller CPLD Angle control, using GPRS technology of information transmission, the use of radio frequency tag for monitoring information to write and read. Software part of the overall design scheme is given, and expounds the generating and read part of the radio frequency tag. Actual test results show that the system can effectively improve the staff behavior monitoring accuracy, satisfactory results have been achieved.
