Design Of Upper-Computer Software And Error Handling For Measurement System Of Pantograph Slide Plate's Abrasion

High-speed locomotive get electric power from power supply web through pantograph, and stable contact between slide and wire is an important condition for electric locomotive collecting energy. However, with the enhancement of train's speed, contact force between slide and wire will change to make the system produce surge vibration by oneself that can lead to slide and wire apart because of high vibration amplitude. Offline for locomotive traction power supply is very harmful, this can cause adverse of locomotive getting electric power,leading to instability of locomotive running and accelerating abrasion between slide and wire. So understanding the surface of pantograph splide plate abrasion is necessary for the electric locomotive in order to maintenance and replacement timely. This system based on methods with existing abrasion detection designs a new detection system of pantograph slide plate's abrasion by utilizing ultrasonic sensors as detecting elements, for it is simple for processing information,low cost,easy to realize hardware and accurate of the measurements.Upper-computer software used Access database to store the data, provided vc++6.0 with programming environment to write human-machine interface and employed object-oriented methods, which based on MFC technique. According to the character of ultrasonic sensor detection system for the abrasion of pantograph splide plate, PC interface are divided into different modules such as pantograph splide plate graphic display and abrasion graphical displays for pantograph splide plate, the show for database, the show for the buttons of image transformation, the show for the condition of the serial port and vehicle speed. Detector datas that get through MSCOMM serial program will be evaluated, processed and stored in the database. The abrasion graph of pantograph splide plate will be drawed according to the datas that kept into database and transformed under the OpenGL window. The experiment indicated that the PC software achieved online, multi-point and time-sharing detection, friendly interface.
