System Design for a Mini-Type Remote Maintaining Terminal Device Based on a Telephone Network
The remote maintaining and diagnosis technology is very important for the distributed and distant on-the-spot equipments and devices for monitoring, predicting, and diagnosing failure. This paper presents a new kind of mini-type remote maintaining terminal devices based on a telephone network. The system design and implementation is described in detail in the paper. The device is composed of a integrated circuit, telephone dial unit, modulation unit, central processing unit, button input unit and display unit. The mini-type remote maintaining terminal device communicates and exchanges information with the distributed and distant on-the-spot equipments and devices for monitoring, predicting, and diagnosing failure. The data is transmitted through the public switched telephone network (PSTN). It can communicate with remote equipments, gather the various parameter data of the devices such as power, power factor, and frequency from the remote industrial equipments. It can also be used to control the remote devices. In the paper, the hardware and circuit design is described in detail. The device is practically very important for monitoring, predicting, and diagnosing failure with a low total cost.
