温室环境监控系统通信技术综述

A Review on Communication Technologies Applied in Greenhouse Monitoring System

本文分有线及无线传输方式对温室环境监控系统中的信息传输技术进行综述。有线传输方式包括RS-485总线及CAN总线,无线传输方式包括ZigBee、蓝牙、WIFI、GSM/GPRS技术等。此外,对各种传输技术的优缺点进行比较,提出了温室环境通信技术的发展方向,认为无线传输方式特别是无线WIFI将会是未来的发展重点。

This paper reviewed the communication technologies including cable and wireless communication modes applied in greenhouse measurement and control system. The cable modes of both RS-485 bus and CAN, and the wireless modes including ZigBee, Bluetooth, WIFI and GSM/GPRS technology were introduced. All the communication technologies presented in this paper were compared. The development trend of communication technology in greenhouse monitoring was proposed. The wireless communication, especially the WIFI technology, would be the developing focus.
