摘　　要：分析多间低温冷库温度集中监测系统的设计方案、硬件系统和软件系统。该温度集中监测系统采用PC机与数据采集控制器进行通讯,对组态软件进行二次开发,实时采集监测温度。运行试验表明,该系统具有性能稳定可靠、安装简单、监测精度高等特点,具备温度的实时动画显示、趋势曲线、数据库查询、报表输出打印等功能。Analyzes the design scheme, hardware and software of central monitoring system for multi low temperature cold storages. The system, based on the secondary development of configuration software （monitor and control generated system）, could collect and monitor all temperatures through the communication in real time through the commu- nication between personal computer and dat^collecting controller. The experimental results prove its advantages of steady performance, sample installation, high monitoring precision, and its function of real-time data recording ＆ displaying, dynamic ＆ historical data curve, database query and report forms printout.
