Pantograph slide plate upper wear detection system software design and error handling machine

By high-speed locomotive pantograph contacts get access to electricity from the pantograph and contact wire contacts the stability of the train by the flow of an important condition for good. However, as the train speeds increase, bow interconnection contact force will change, the system will generate self-excited vibration, vibration amplitude over the General Assembly and the resulting slide pantograph catenary wire separation phenomenon occurs offline. Offline for electric locomotive traction power supply is very harmful, not only cause bad motorcycle by the flow, causing unstable locomotive to accelerate the catenary and pantograph slide wear. To understand and pantograph slide on the wearing of the surface normal by the flow of electric locomotives is necessary in order to pantograph timely maintenance and replacement. This system has been integrated in the current industry pantograph wear detection methods based on the use of ultrasonic sensors information processing is simple, inexpensive, easy to implement hardware, ranging accurate, and designed an ultrasonic sensor as the detection element to the new pantograph wear detection system. The main job is to design a detection system of the host computer software and the data detected error analysis. Access database with a host computer to save the data and the preparation of VC 6.0 compiler environment as man-machine interface, based on MFC technology, object-oriented approach. Based on the ultrasonic sensor detects the pantograph slide wear characteristics of the host computer system interface is divided into skate graphics and skate wear curve display, database, display, graphic display change key, serial status display, speed display different functional modules. Serial program reads through the lower MSCOMM distance measurement situation, the detected data assessment and processing errors and save data in the form at the interface. Save in OpenGL window, according to data from the wear of the pantograph to draw graphs and image processing. The experiment shows that the PC software with an online, multi-point, time test, friendly interface.
