Embodiment Construction

[0011] The data acquisition system of electric locomotive operation status is mainly composed of signal acquisition and processing circuit, data storage circuit and data display circuit. Each unit is a relatively independent module, and the modules are connected by data communication. The electronic cabinet of the locomotive summarizes the electrical signals of the train running status. These signals reflect the current of the drag motor during the operation of the electric locomotive, the running speed of the locomotive, the magnitude of the excitation current, the traction and braking signals, the voltage of the internal DC power supply, and the trigger pulses of the thyristors in the main circuit of the four drag motors of the locomotive. No status information. The signal acquisition and processing circuit is placed in the electronic cabinet, which needs to collect up to hundreds of signals. The data storage circuit is located in the specified data box, and it is required ...

Abstract

An electric locomotive running state data acquisition system is composed of a signal acquiring and processing circuit, a data storage circuit and a data display circuit. The above circuits are in data communication in a serial communication mode among one another, the signal acquiring and processing circuit is arranged in an electronic cabinet of a locomotive, the data storage circuit is arranged in a data box of the locomotive, and the data display circuit is arranged in a locomotive cab; the signal acquiring and processing circuit comprises an analog signal processing circuit, a digital signal processing circuit, an A / D (analog / digital) conversion circuit, a data acquisition circuit and a serial communication circuit, LMl124 is adopted by the analog signal processing circuit, TLC1543 is selected and used by an A / D conversion chip, the digital signal processing circuit comprises ISPl032, the digital signal processing circuit and the A / D converter are connected to a microcontroller, and a half-duplex communication chip is adopted to the serial communication circuit. The electric locomotive running state data acquisition system is stable and reliable in system running, and locomotive running state can be accurately acquired and processed.

Description

technical field [0001] The invention relates to an acquisition device, in particular to an electric locomotive running state data acquisition system. Background technique [0002] The SS4 electric locomotive is an eight-axle heavy-duty traction freight locomotive running on the main railway line. The electronic devices and sensor circuits inside this type of locomotive provide a large number of signals about the operating status of the locomotive to the gauges. These signals can fully reflect the working conditions of the electrical circuit system and mechanical transmission system inside the locomotive. Train operators should regularly record the real-time data on these measuring instruments, and keep a large amount of recorded data for locomotive performance improvement and failure analysis. However, the traditional operation state data record not only cannot realize the real-time tracking and recording of state information, but also is not conducive to the processing an...
