Complex sensor device for working condition of vehicle

The invention relates to a complex sensor device for the working condition of a vehicle, which comprises a sensor, a data collection module, a data storage module and data processing units, wherein the units are mutually connected and communicated by CAN/RS-232/RS-485 interfaces, the sensor collects the data of the working condition of the vehicle and transmits the data to the data collection module, the data collection module transmits the data to the data storage module for storage and the data processing units for processing, the processed data are transmitted to the outside and transmitted to a ground monitoring center so as to be convenient to carry out fault diagnosis, and a decision basis of fault processing can be provided to the driving of a train. The complex sensor for the working condition of the vehicle plays important roles of an information source and preprocessing in the entire monitoring system for the condition of the vehicle and provides guarantee for enhancing the traffic operation safety
