Abstract
The invention discloses a wireless-based pantograph state monitoring system. According to the system, pantograph state data collected by a sensor arranged on a pantograph and a camera arranged at the roof of a train are all transmitted to a train-mounted data acquisition host computer; after being subjected to preliminary data processing by the train-mounted data acquisition host computer, the pantograph state data is sent to a ground server through a wireless communication module, the ground server sends the data to a ground client-end computer through the Internet, and the ground client-end computer receives the pantograph state data and further processes and displays the data, and thus, the purpose of remote state monitoring of on-road train pantographs can be achieved. The system solves the problem that the traditional pantograph state monitoring system fails to transmit high-capacity pantograph state and video data, and not only can achieve dynamic detection and record of on-road train pantograph states in a ground scheduling and management center but also can accurately search and fix pantograph fault points.
