本文叙述了单片微型计算机控制的智能电话自动拨号装置的电路结构、原理和调试方法,本装置被安装在程控电话机的电话线路上,若被信号触发,就可将存储在内存中的电话号码拨发出去、传呼的电话号码可以通过用户电话随时写入内存中,它可以是自动传呼BP机号码,也可是指定的用户电话号码,该装置设有一个密码,若对装有此装置的电话拨号,振铃五次后,写入密码,即可自动解除拨码. This article describes the circuit structure, principle and debugging method of the single-chip microcomputer-controlled smart phone automatic dialing device. The device is installed on the telephone line of the program-controlled telephone. If the signal is triggered, the phone stored in the memory The number is dialed out. The paged phone number can be written into the memory at any time by the user’s phone. It can automatically page the BP number or the designated user’s phone number. The device has a password.
