A intelligent temperature difference monitoring system is designed to realize remote view of temperature measure⁃ment data and control the temperature difference between indoor and outdoor of greenhouse. In this system,the temperature of greenhouse can be real⁃time adjusted. The field testing data can be dynamically displayed and backup in remote computer. The measurement result can be analyzed at anytime. The actual operation result shows that this system can meet the design requirements.% 为了实现温室内外温差的自动控制，设计了一种远程智能温差监控系统，该系统能根据要求实时调节温室温度、远程动态实时地显示现场测试数据、海量测试数据的自动备份，并能随时调用数据结果进行分析。实际运行结果表明该系统达到设计要求。
