Vehicle-mounted interface equipment and data acquiring and processing method thereof

Abstract

The invention relates to vehicle-mounted interface equipment and a data acquiring and processing method thereof. A microprocessor control module outputs an instruction to an equipment monitoring module, and the equipment monitoring module controls signal output to cut off the output of a train digital quantity output module and a sensor interface module; the microprocessor control module receives the status information of a sensor interface module and a bus interface module, communicates with an upper machine according to format protocol, simultaneously receives control information sent by the upper machine and transmits the control information to the bus interface module and a train traction control module to execute. The acquisition of the status information and the position information of a train is realized, and necessary input output is provided for the automatic operation control of a vehicle-mounted control system. Meanwhile, the equipment monitoring module has a fault orientation safety function of carrying out real-time monitoring on a device and a train line, and the running safety of the train is ensured. In addition, three redundant power inputs of an external power supply input module and the train traction control module working in a hot spare mode increase the reliability of the vehicle-mounted interface equipment.

Description

technical field [0001] The invention relates to a data collection technology, in particular to a vehicle-mounted interface device and a data collection and processing method thereof. Background technique [0002] China's rail transit equipment mainly relies on imports, which are expensive, which limits the expansion of my country's urban rail transit system to a certain extent. Since the implementation of the localization policy of urban rail transit equipment, the localization of China's urban rail trains has achieved remarkable results. Domestically produced urban rail trains continue to emerge, and the ability of independent innovation has been significantly enhanced. The upsurge of urban rail transit construction has been set off one after another across the country, and the market demand for domestic rail transit equipment has increased significantly. However, the urban rail transit signal data acquisition system is currently still dependent on imports, which provides ...
