基于单片机的野外作业移动库房安防系统设计

Design of a Surveillance System for Fieldwork Mobile Warehouse Based on Single-chip Microcomputer

介绍了一种野外作业移动库房安防系统的设计和实现方案。该系统以C8051F120单片机为主控制器,以STC89C52单片机为从控制器,以热释电红外感测器D203S为核心构成人体检测模块,以烟雾传感器MQ-2为核心构成烟雾检测模块,采用CRM2400TNC无线模块实现主、从控制器之间的通信,可实现库房内人员监测、烟雾检测以及库房物品进出情况监测及报警功能,且只有输入正确的密码才能关闭报警系统。测试结果验证了该系统的有效性和可靠性。

The paper introduced a design and realizing scheme of surveillance system for fieldwork mobile warehouse.The system takes C8051F120 single-chip microcomputer as main controller,STC89C52 as slave controller,D203S pyroelectric infrared sensor as a core of human-body detection module and MQ-2 smoke sensor as a core of smoke detection module,and adopts CRM2400TNC wireless module to realize communication between main controller and slave controller.The system realizes functions of personnel monitoring and smoke detection in warehouse,monitoring of valuables into and off the warehouse as well as alarming.What＇s more,alarming system cannot be closed until inputting correct password.The testing result showed the availability and reliability of the system.
