基于PSTN网关的家庭网络远程控制实现方法

Realization method of remote controller in home network based on PSTN gateway

为了利用公众电话网实现对信息家电的远程控制,介绍了家庭网络中一种蓝牙公众电话网(PSTN)网关的实现方法,提出了一种无须PC机和利用已有网络对家庭网络内信息家电进行远程控制的解决方案。简单介绍了家庭网络及其主要技术,重点介绍了家庭网络中嵌入式蓝牙PSTN网关的功能、实现方法以及为提高性能所做的改进方案,进行了功能测试并给出了性能结果评价。利用研制的PSTN网关实现了对春兰集团公司提供的洗衣机、空调等多个家电设备的远程控制并通过了功能验证。功能测试表明,该系统达到了设计初期的各项要求。

In order to control information appliances （IA） remotely by PSTN, a realization method of bluetooth PSTN gateway was introduced, by which people can control IAs in the home network remotely using existing network without a PC. The main technologies of home network were introduced briefly. Then the function,realization method and some improvement for enhancing the performance of embedded bluetooth PSTN gateway in home network were analyzed in detail. The function was tested, and then the performance evaluation was brought forward. The PSTN gateway developed by us can control several appliances such as the washer and air conditioner manufactured by Chunlan Company, and has passed the function verification. The test result proves that this system meets all the requirements of the design.
