软件验证输入要素有效防止真空热处理炉发生误动作

Identifying Effectiveness of Input Elements by Software Prevents Malfunction of Vacuum Heating Furnace

随着真空热处理炉程序控制器模块化、自动化程度的提高,所用的程序不例外地增大了软件规模,从而增加了误动作发生的概率。误动作的防范措施要有针对性、可行性、有效性,为了使真空热处理炉正确、迅速、灵敏地完成动作,有效的组态软件脚本连锁、传感器的抗干扰措施、程序控制器软件互锁、硬件连锁相互制约是防止误动作发生的方法。为此,探讨软件互锁和相互制约方法,特别是软件验证输入要素的有效性是真空热处理炉程序运行的前提,它可有效防止误动作的发生,因此汲取真空热处理炉的各种类型输入要素软件所用的验证方法进行讨论。

The continuous modularization and automation of vacuum heating furnace controller have urged increase in the scale of software without exception.However,this also leads to rise of malfunction probability.The prevention of malfunction needs pertinence,feasibility and validity.In order to make vacuum heating furnace complete the action properly,rapidly and sensitively,the methods can be used to prevent the occurrence of malfunction including effective script interlock of configuration software,Sensor Anti-Jammin measures,interlock of procedure controller software and mutual restriction of interlocking hardware etc.The interlock and mutual restriction methods of software are discussed in this paper.In particular,identifying input elements effective by software is the precondition of vacuum heating furnace program execution,which prevents the occurrence of malfunction effectively.The paper also discusses the methods using various types of software with input elements from vacuum heating furnace.
