Development Of Turntable Automatic Test System

The essay taking the antenna test turntable as the research object, discussedthe design thought and the realization method of founding a set of turntableautomatic test system.This article introduced the topic background and the significance in theintroduction, elaborated two kinds of structural style of the turntable computercontrol system, and outlined the topic main work. After that it elaborated thesystem design thought of the antenna test turntable automatic test system in thearticle second chapter, including the equipment composition of the antenna testturntable, the technical specification request, the introduction of the electricallycontrolled system and the goniometric system, and elaborated the test systemsoftware platform design proposal.The antenna test turntable automatic test system used the multi-machinecollecting and distributing controlling mechanisms in this article. The lowerposition machine realized the real-time control of the electrically controlledsystem and the goniometric system, keeping the communication with the upperposition machine, and fed back the turntable condition information, and so on;The upper position machine realized the data acquisition of the various axialangles, the transmission of the control command and the monitoring of thecurrent turntable running status, and so on. It used parallel correspondence andthe asynchronous serial communication between the upper position machine andthe lower position machine. The parallel interface used the self-made PCI9052data acquisition card, using for the data acquisition in the upper position machine;The serial interface used the RS232 standard interface, using for the movementcontrolled command transmission between the upper position machine and thelower position machine.The entire test system software platform was constructed on the Windows2000 operation system, because under this system the application procedure isunable directly to access the hardware equipment and needs the hardwareequipment driver, therefore elaborated the concrete method of the PCI9052 data...
