温箱控制器的运行控制文件测试与研究

Test and Research of Operation Control File for Temperature Controller

摘要:

为了建立综合控制台对温度试验箱进行集中控制,需要对各独立的温控试验箱的运行文件进行分析和整合,形成可被温控试验箱执行的*.PRG程序文件。方法是首先通过原系统操作界面程序,设定温箱工作温度和时间,产生一个温箱控制器执行的*.PRG文件。然后,用Beyond Compare工具,对此(二进制)文件进行测试分析,得出文件的开始标志,温度阶梯步数,温度值单元,温度点切换时间单元,切换点行标志和文件结束标志等6个部分的位置关系,从而获得温箱控制器运行文件*.PRG的内部结构。根据文件内部数据结构关系,可以建立符合原*.PRG文件格式且可通用的可执行程序文件。在某型综合控制台的设计中采用该方法建立的*.PRG文件对各试验箱进行独立运行实验,实现了对温箱的综合控制。

Abstract:

In order to establish an integrated console for centralized control of temperature test chamber,it needs to analyse and integrate for the running file of separate temperature-controlled test chamber so that can be performed a *. PRG program file. First,it sets work temperature value and time of temperature chamber through the operation interface of original system to format a executable *. PRG file for the thermostat controller. And then,using Beyond Compare tool to test and analyse the (binary) file in order that it can draw location relationship of six parts including the file start flag,the temperature stepped number,the temperature value position unit,the temperature point switching time,the temperature switching point line flags,and the file ending sign and so on. So it can derive the internal structure of running *.PRG file from thermostat controller. According to the documents of internal data structures,a general executable file which meets the original format requirements is established. In the design of a certain type of integrated console,the *.PRG file through the above method formatted is used to the test of each independent temperature chamber that achieves a comprehensive control for each temperature chamber.
