摘要
为了实现用户远程控制,设计了一种以PH8810电话接口模块为核心的DTMF信号远程监控系统。系统通过电话网络实现远程监控,不需要专门的布线,抗干扰能力较强。实验证明,移动控制端可通过发送正确的用户指令码实现本地的操控,当环境温度异常时控制板可向用户拨号实现报警,实现远程监控功能。
In order to achieve users＇ remote control, a DTMF signal remote monitor system based on PH8810 telephony interface module is designed. This system can realize the remote monitoring and control by the telephone network with no special wiring and has strong anti-interference ability. The experiments prove that the mobile control terminal can achieve local control by sending correct instructions from a user. The control board can also dial users to give an alarm when ambient temperature is abnormal, thus realizing remote monitoring function.
