文章介绍了一种利用电话网络将传感器和计算机联系在一起的传感器计算机控制系统。由于利用已有的电话线路进行信号传输，该系统可实现远距离控制，而造价却较低，更兼有计算机的参与，使整个系统具有较高的智能化，非常便于管理和维护。这种系统的缺点是实时性不高。 This article describes a sensor computer control system that uses a telephone network to associate a sensor with a computer. As the signal transmission by using the existing telephone lines, the system can achieve long-distance control, but the cost is lower, but also the participation of the computer, so that the entire system has a higher intelligence, very easy to manage and maintain. The disadvantage of this system is not real-time.
