基于ZigBee技术,采用CC2420芯片和PIC18F4620模块的C51RF-3-JX开发板的智能家居系统进行实验性研究。对智能家居系统中的中心控制、门锁信息采集和锁窗控制3个模块进行了硬件设计,确定了微处理芯片与射频芯片和外设的连接方式,对电源电路、接口电路、信号转换电路和指示灯电路做了设计和分析;实现了微处理器对射频芯片的控制以及射频芯片网络的搭建。最后通过测试接口数据验证了数据发射和接收效果。
Based on the ZigBee technology, a smart home system using CC2420 chip and PIC18F4620 C51RF-3-JX development board is used for experimental research. The hardware design of the three modules of the central control, door lock information collection and lock window control in the smart home system was established, the connection mode between the micro-processing chip and the radio frequency chip and peripheral devices was determined, and the power supply circuit, interface circuit, signal conversion circuit And indicator light circuit to do the design and analysis; to achieve the microprocessor control of radio frequency chips and RF chip network structures. At last, the data transmitting and receiving effects are verified by testing the interface data.
