摘要
针对室外远程控制室内家电的不便性问题,利用SIM900A、红外以及嵌入式等先进技术,从应用角度出发,提出了一种远程红外家电控制方法。基于SIM900A远程通讯模块,使得在室外能够与室内嵌入式控制系统进行通信。红外遥控采用自学习型,测量脉冲宽度并存储数据,利用嵌入式系统模拟发送38 kHz载波信号,实现对各种家电遥控器的学习。实践表明,该控制系统可以解决远程家电控制问题,且室内无需布线、成本低廉,系统稳定可靠、功耗较低。
For the inconvenience of outdoor remote controlling indoor appliances, a new infrared remote appliance control was presented by making use of SIM900A, infrared and other advanced technologies embedded, from the view point of application. Based on the SIMg00A remote communications module, the communication of the outdoor and indoor embedded control systems becomes possible. In the infrared remote control, a self- learning was used to measure the pulse width measurement data coding and compression, while the embedded system analog was used to send a carrier signal of 38kHz to achieve the learning of a variety of home appliances remote control. Practice shows that the control system can solve the remote appliance control, and also has the advantages of low cost, low power consumption, stability and reliability, and no need for wiring indoors.
