Multiple Test Instrument Data Acquisition And Control System

The main content of this paper is to design and implement a multi-testinstrument data acquisition and control system. Different types of test equipment inindustrial environments were used to separate the traditional model of CNC systemfor data acquisition and control. The system will based on these drawbacks, makevarious different types of test systems into one system to achieve a unified monitoring,centralized control, so that it can reflect more macro entire production process toimprove production efficiency and avoid waste of resources.The innovation of system is through the types of test equipment analysis andresearch during industrial production, equipment information abstracted into a unifiedinformation resource table and stored in test equipment. After test equipmentconnected to the PC successful, test instruments will sending their resource table tothe PC that builds a virtual test equipment module.PC uses virtual module obtainsfurther data collection instrument testing and implementation of test instrumentscontrol. This design can mask different test equipment, access several standard testequipment to one system through the only standard that achieves data acquisition andcontrol task together with types of test equipment.The system of lower computer is composed by test instruments and STM32microcontroller.MCU transit server functionality. It will be packing test instrumentdata, sent to the PC that reduces amount of equipment direct access that system cancontain more equipment. PC system under VS2010platform is using MFC to research,data transmission based on TCP/IP protocol standards.PC system can auto scan andconnect work state in the industrial Ethernet environment that enable to connectseveral lower machine. Also, through multi-threading, PC system could establish andindependent communication process controller system, thereby obtaining lowermachine data collection and implementation of control to the next. According toactual demand, PC systems also prepared a database and the administrator module.The system realizes the requirements of the subject. Since many times of simulationtest is running well, it can provide the system design is feasible.
