设计了一种风机水帘恒温控制系统,其中温控系统采用双路 PT100温度传感器采集温度,单片机根据接收到的数据计算PT100的阻值,依据PT100的温度-电阻特性求出监测目标区域的环境温度,继而控制风机水帘的工作状态和报警装置,实现温度的自动控制和过限报警功能.Proteus仿真结果表明,本系统在温度控制方面完全能够根据环境温度合理调整风机水帘的工作状态.%In this paper,the temperature control system using a dual PT 100 temperature sensor to collect temperature is designed.The microcontroller calculates the resistance of the PT 100 based on the received data.According to the temperature-resistance characteristic of PT 100,the ambient temperature of the monitoring target area is obtained.And then the operating status of the fan curtain and alarm device to achieve the temperature of the automatic control and limit alarm function are controlled.Proteus simulation results show that the system in the temperature control can be fully adjusted according to the ambient temperature fan water curtain working conditions.
