无线网络前端设备社区安防系统研究

Research on Community Safety System Based on Wireless Network Front-end Devices

针对有线社区安防系统存在的问题,研究并提出了无线网络前端设备社区安防系统结构,并实现了无线网络门禁终端设备.首先以SoC微处理器C8051F126为门禁控制器主CPU,CC2480为ZigBee网络处理器,C8051F002为Wiegand接口转换处理器,设计了ZigBee无线网络门禁终端设备;然后采用C语言及ZigBee协议栈应用编程接口(API)对门禁编程;最后制作了原理样机.通过试验、调试和修改,实现了门禁的主要功能.

According to the existing problems of cable community safety system,the architecture of the community safety system based on wireless network front-end devices is researched,and wireless network entry front-end device is implemented.First,the ZigBee wireless network entry front-end device is designed based on the SoC microprocessor C8051F126 as the entry main CPU,and CC2480 processor as ZigBee network processor,and C8051F002 for conversion from Wiegand interface to UART interface.Then,the C language and application programming interface（API） for ZigBee protocol stack is used to program the designed entry.Finally,prototype of the entry is made.Through the test,debug and modification,the entry main functions are realized.
