一种低成本数据采集监测系统的研究与应用

Research and Application of a Low Cost Data Acquisition and Monitoring System

无线发射台的智慧化发展已经成为一种趋势,而前端采集是其中最重要的环节之一。本文针对发射台安全播出工作遇到的问题,研制了一种采集器,实现发射机射频功率采集和光照度采集,并通过以太网上传数据到局域网。射频功率检波模块选用AD8362芯片实现,该模块具有检测线性范围大、检测准确、实现简单、方便操作及性价比高等特点;采用通用软件,将采集器和现有设备部署到一张网络进行统一管理,实现对不同类型设备的集中监控。该方案开发成本低、周期短、实用性强,能够保障广播电视的安全播出。

The intelligent development of wireless transmitter has become a trend, and front-end acquisition is one of the most important links. Aiming at the problems encountered in the safe broadcasting work of the transmitter, this paper develops a collector to collect the radio frequency power and illumination of the transmitter, and upload the data to the local area network through Ethernet. The RF power detection module is realized by AD8362 chip. The module has the characteristics of large detection linear range, accurate detection,simple implementation, convenient operation and high cost performance;general software is used to deploy the collector and existing equipment to a network for unified management, so as to realize centralized monitoring of different types of equipment. The scheme has the advantages of low development cost, short cycle and strong practicability, and can ensure the safe broadcasting of radio and television.
