This paper discusses a new voice-data multiplexing transmission system which can transmit data signals along a telephone line so that the speakers can get remote hand-written texts or diagrams when a conversation is going on. This system uses time assignment method to multiplex (interpolate) voice and data signals and then transmits them along the same channel. Compared with the usual frequency division system, this system can improve the transmission qualty. Another feature of this system is that it possesses the capability of on-line identification, that is, data and voice signals can be idsntified and dispatched in real time according to their inherent features. As a result of no identification signal, this sysem can raise the efficiency of telephone channel.In this paper,a new method of on-line identification (conversion and cascade method) , which was at first proposed for this system, is described.This method simplifies the system with higher accuracy.

本文探讨的是一种新的话音——数据混合传输系统。它可以在通话同时传送数据信号,使对话双方能及时见到所讨论的数据、文字与图形。本系统特点之一是采用时间分配体制解决两种信号通过同一信道传输的问题。即在话音间隙中传送数据。由于每种信号均可占用全部电话频段,与已有的频分系统相比能改善信号传送质量。本系统的另一特点是具有在线识别功能,在发送端无须发送附加的标志信号,接收端根据话音与数据的特点实时地在进行识别与分遣,从而提高了信道利用率。文中介绍了一种新的在线识别方法(变换——分步法),它具有线路简单和识别准确的特点,是作者为解决本系统中两种信号的识别问题而提出的。

This article introduces a new data acquisition software for Distributed Dam Safety Monitoring System (DDSMS). This software is installed on CCU (Central Control Unit) and performs as the heart of DDSMS. It controls the data and instruction flow of the Data Acquisition Network and can send various instructions to the MCU (Measurement Control Unit). After receiving these instructions,the MCU measures all the instruments installed on the concrete embankment dams on the reservoir, then transmits the data to CCU. The software processes the data received and strores it in the database on CCU and emits alarm when an instrument is not responding, malfunctioning, or indicates trouble. Through the interactive interface users can keep track of real time water resource and dam condition. High level management hosts from a ministry office can also obtain data from CCU using a telephone line and modem. With the initialized operating parameters in the software, an unmanned DDSMS can be realized.
