分布式环境监测系统中的温度监测设计

为了监测铁路信号楼的环境，确保机房设备及计算机、通信网络的可靠运行，设计了分布式铁路信号楼监测系统，在此主要阐述其温度监测的设计。温度监测系统能够进行多点测量，并在主监控计算机界面上进行显示。对于温度超限会产生报警信号，进行监测数据的记录、分析，实现多种故障的预测。系统基于CAN总线的分布式设计，实现监测系统的实时、可靠，达到监测系统的灵活性、智能化。

Design of Temperature Monitoring in Distributed Environment Monitoring System

To supervise the environment of railway signal building and to insure the reliable operation of equipment, computers and communication network, we designed a distributed monitoring system for the railway signal building. This paper mainly addressed the design of temperature monitoring in this system. Temperature monitoring system can acquire data from multiple points, calculate the average temperature of the surroundings, and display the results on the display. It can also generate an alarm when temperature exceeds the limits. The system adopts CAN bus to fulfill the requirements of high speed, high reliability and easy connection. In addition, virtual instrument is applied to achieve flexibility and intelligence.
