Research And Design Of Car Seat Bumps Motility Test Equipment Control System

The subject comes from Shanghai LianNeng Electromechanical Co. Ltd., based onthe analysis of the car seat turbulence peristalsis test equipment technology action andindustry on the basis of technical requirements, Choose to contain serial interface RS232extended PLC as the main hardware controller, the host machine using the LabVIEWreal-time detection and treatment of process data, Eventually completed the car seatturbulence, peristalsis and drop test process automation and visual tests. Through theanalysis of QC/T740-2005technical standards, proposed to use NI PCI6221precision dataacquisition card, direct measurement of the displacement sensor data.This paper studies the programmable logic controller (MITSUBISHI-FX1N-60MR-type) and the host computer LabVIEW monitoring software, the seat bump the peristalticautomated test equipment. According to the process moves and technical standardrequirements of the industry, Complete the whole experiment equipment selection anddesign of hardware and software programming electric; use OPC(OLE for Process Control)technology to complete the PLC through the RS232serial port with the host LabVIEWapplication in real time and accurate communications; Realize the site electricalcomponents of automatic control and process data monitoring; completed the motility testcar seats bumps, and in LabVIEW interface on the host computer to map out the bumpsand peristaltic displacement curve and seat test collapse curve; and during the test theexperimental data to monitor and display the last statements in the form of output data, tofacilitate the call of the engineering and technical personnel and equipment, product of theprocess improvement for reference. The main content of the report output parameters havetest data storage and setting up the test query and the number and frequency, and so on.
