一种新型的分布式数据采集器(一)

A New Distributive Data Acquistition System（1）

介绍了一种新型的分布式智能数据采集系统──ALPHA900系列数据采集器。该采集器由中国航空工业总公司第三0四研究所与英国ADAS公司联合设计研制。它集中了90年代采集器的优点，如可变字长、可编程智能前端、带温度补偿的连接器、可脱机工作等，并为突出各自功能形成系列。该采集器已成功地投入了工业生产，并且应用于工业过程监测、条件监测或加工监测。该系统使用价格低廉的RS485网络，各种型号模块提供了精确的温度、压力、应变及数字事件和频率等数据的测量及控制，并有相当突出的性能价格比。

This article introduces a new intelligent data acquisition system called ALPHA900series, which manufactured by 304th institute of China Aviation Industry Corporation and ADAScompany of UK. It sums up the advantages of the data acquisition systems in 9O's,such as variable bytelength, programmable intelligent front, connections with temperature compensation and so on. Everymodule in this scries has its special function. It has been put into production successfully and used forprocess monitoring, condition monitoring or machine monitoring. Connected by low cost RS485network,the ALPHA 900 modules supply accurate measurement and control for temperature,pressureand strain along with data events and frequency. It also has attractive ratio of performance and price.
