摘要
RS232接口在计算机通讯中应用非常广泛,成为一种标准的串口通讯方式。而RS232无线通讯作为新型的无线连接器也得到广泛的应用。介绍了1种以RS232为标准的无线通讯方式,AT89C52为控制芯片,ER400TRS为无线传输芯片的近距离无线测温系统。经过电路设计,编写程序和测试,数据收发的准确性和稳定性均达到设计效果。
RS232 interface which is a standard serial interface mode has been widely used in computer communication.However,RS232 wireless communication has been extensively used as the new wireless connector.The article introduces a standard wireless communication mode based on RS232.In this mode,AT89C52 is the control chip and ER400TRS is the temperature measuring system of wireless transmission chip within close range.After designing the circuit,programming the program and testing,the preciseness of data reception and transmission has all obtained the expected result.
