GPRS及CDMA替代数传电台的可行性探讨

Feasibility study of GPRS and CDMA network replacing data transmission broadcasting station

数传电台在工业控制领域的应用广泛,目前仍然是工业控制领域的主要传输手段。凭借GPRS/CDMA网络的覆盖广、数据传输可靠性高、组网便捷、成本低廉等因素,GPRS/CDMA的数据传输称为近两年来迅速崛起的数传方式。文章将从两者的传输机制、组网方式等多方面进行比较分析,并提供数传电台网络向GPRS/CDMA数传网络迁升的方案,可作为用户选择数传媒介的参考。

The data transmission broadcasting station has been applied in the industry control field broadly, nowadays it is still the main instrument of industrial control. GPRS/ CDMA is preponderant for its features of broad covering area, reliability of data transmission, easy to generate a network system, low cost etc. GPRS/CDMA data transmissions have become a fast growing data transmission method. This article is going to compare and analyze the transmitting mechanism and network constructing mode. It also provides the scheme of promoting the network from data transmission broadcasting to GPRS/CDMA data transmission. This article can also be the reference for customers to choose a data transmission media.
