Research On The Measuirng Cell Automotive Calibrate Technology

The strength standard plane is the National Measurement Examination Departmentnecessary strength value rationing equipment, takes the national defense regionmeasurement department, the existing equipment or the80s’s product, limited to thecounting level then, the strength standard plane’s electric control part was comparativelybackward, only could realize the manual Canadian Holland, the discharge control, theworking efficiency is low. This article is low in view of the existing release lever typestrength standard plane automatist, the reliability is bad, operation inconvenient and so oninsufficiencies, proposed one kind of release lever type strength standard plane automaticcontrol system. Following are the thesis’s main research work and achievements:1. Through to the release lever type strength standard plane system structure, theduty and the performance demand analysis, proposed the resistance dynamometerautomation calibration systems control plan.2. Establishes a set of resistance dynamometer automation calibration system,through takes the lower position machine using PLC and the superior machinecommunication working pattern establishment system’s hardware platform; On thesoftware, proposed and has realized based on the VB resistance dynamometer automatedsystem calibration software, has realized the visualization control, the visualizeddemonstration.3. The binding force standard plane’s examination practice, proposed and hasrealized the fault dictionary law in the resistance dynamometer automation calibrationsystem accident warning and the failure diagnosis application, effective safeguardssystem work reliability.4. For the improvement strength standard plane’s examination performance, throughto the release lever type strength standard plane survey principle’s theory modelling andthe analysis, proposed with enhances the release lever center of gravity and reduces therelease lever movement friction force the method to enhance the strength standard planeto limit keenly; Has analyzed the release lever type strength standard plane’s strengthvalue error and the origin, and gave reduced the strength value measurement error’smeasure.This control system has realized the strength value measurement and the dataprocessing automation, improved the strength standard plane’s serviceability, reducedoperators’ labor intensity, raised the examination efficiency, eliminated the human factorto the measuring accuracy influence. The application result indicated that this systemoperation is simple, the stable property is reliable.
