摘要
起重机械作为重要的搬运设备,其安全可靠运行意义重大。针对起重机械控制柜环境温度的需求,分析了各种工况下最不利的环境因素,针对恶劣工况的特殊需求,研究了各种温度传感器的特性和优缺点,选择DS18B20作为温度传感器,搭配STC12C5A08S系列打片机,设计了相关的电路,编写了控制代码,完成了温度监控下位机;上位机程序采用开发测量或控制系统的最常用的图形化开发环境LabWindows/CVI编写。最终形成了一套简单实用的起重机械控制柜温度监控系统,实现在起重机械使用过程中对控制柜进行实时环境温度监控,并在温度漂移出预设温度值时发出警报,为起重机安全运行提供保障。
As an important handling equipment,the safe and reliable operation of lifting machinery is of great significance.The most unfavorable environmental factors under various working conditions were analyzed according to the requirements of the environment temperature of the crane control cabinet,the characteristics,advantages and disadvantages of various temperature sensors were studied according to the special requirements of the bad working conditions,DS18B20 was selected as the temperature sensor,matched with STC12C5A08S series printer,the relevant circuit was designed,the control code was compiled,and the temperature monitoring lower computer was completed.The upper computer program was written in LabWindows/CVI,the most commonly used graphical development environment for developing measurement or control system.Finally,a set of simple and practical temperature monitoring system for crane control cabinet was formed,which realized real-time environmental temperature monitoring for the control cabinet during the use of crane,and sent out alarm when the temperature drifted out of the preset temperature value,so as to provide guarantee for the safe operation of crane.
