Through analyzing the production course of the mechanical equipment of thebulk terminal, combining virtual reality technology and mechanical designing technique, base on Flexsim and VC. net to set up kinematics model, realize the action of the unloading equipment object in processes of simulation.
The procedures are that equipment object is created with serial(), visa() and gpib(), the attribute of equipment object is set with set(), the connection of equipment object and hardware equipment is realized using fopen(), data acquisition for hardware port is realized with fprintf(), fscanf() etc, and equipment object is closed or deleted with delete() or clear().
The difference between TTC station system and normal industrial control system is analyzed. According to configurable software design,object-oriented equipment model and display model are deduced. Equipment parameter,data process method,communication channel are defined for the equipment object while both static and dynamic graphic attributes,display style and the relationship with equipment parameter are defined for the graphic object.
An equipment object contains two main types of information on the equipment item.

Based on object -oriented method,the software and hardware design principle of process measure & control system are introduced in this paper. The process objects are split into unit object (managed by intelligent object managing card ) and equipment object (managed by main computer), which reflects the essential of process control more perfectly. Furthermore, the advantages on system re -usability, open structure, extension etc. are enhanced.
There are methods of Matlab ToolBox and Mex file for data acquisition of hardware port realized with Matlab. Matlab ToolBox is implemented with function. The procedures are that equipment object is created with serial(), visa() and gpib(), the attribute of equipment object is set with set(), the connection of equipment object and hardware equipment is realized using fopen(), data acquisition for hardware port is realized with fprintf(), fscanf() etc, and equipmen...
The current monitoring and control system in TTC station does not fit with the rapid development of space technology due to its mass cost,long development period,less flexibility,hard maintenance caused by without enough commercial software support,its small scale and the complicated TTC equipment.The difference between TTC station system and normal industrial control system is analyzed.According to configurable software design,object-oriented equipment model and display model are deduced....
