Diesel locomotive running data recording device

Abstract

A service data recording device for a diesel locomotive comprises a main-control component, a communication component, a signal acquisition and output component, a drive lamp display component and a power component, wherein the main-control component is used for realizing the logic control of locomotive data collecting, and the function of data logging, dumping and communication; the communication component comprises an RS422 / 485 serial port circuit, an RS232 on-line debugging communication circuit, an Ethernet interface and a USB interface circuit; the signal acquisition and output component comprises 16 quantity value acquisition circuits, 2 voltage-mode analog quantity acquisition circuits and 2 current-mode analog quantity acquisition circuits, 2 frequency signal acquisition circuits, an analog quantity output circuit and 4 digital quantity output circuits; the drive lamp display component is used to display the running state of the data logging device; and the power component is used to provide power supply for the above-described circuits or components. The invention has the advantages of simple and compact structure, low cost, and simplicity and convenience in operation, greatly improves the product reliability and flexibility, and enlarges the application range by configuration.

Description

technical field [0001] The invention mainly relates to the field of diesel locomotive operation control systems, in particular to a diesel locomotive operation data recording device. Background technique [0002] For a long time, the locomotive operation monitoring and recording device has been used in the domestic diesel locomotive operation data monitoring, that is: through real-time communication with the ground signal machine, to monitor the locomotive running status to prevent the locomotive from running illegally; and to change the excitation device according to the locomotive running status to record the ground signal machine , locomotive speed, operating conditions and other data. At the same time, the locomotive operation monitoring and recording device is also equipped with a display screen for human-computer interaction. However, the traditional locomotive operation monitoring and recording device has complete functions, the monitoring system is too large, the eq...

AI Technical Summary

Problems solved by technology

However, the traditional locomotive operation monitoring and recording device has complete functions, the monitoring system is too large, the equipment includes the uploading system and the ground system, the overall cost is high, and the whole system must cover the entire railway system, for foreign countries without ground system configuration Diesel locomotives are not applicable for export

[0003] Another practitioner has developed a data recording device, but it is limited to the RS422 communication method and relies on third-party equipment to collect data. The level of the entire structure is weak, and it cannot meet the strength requirements of the black box structure, that is, it cannot be guaranteed in the locomotive. Data security in case of accidents such as impact; moreover, limited storage capacity cannot meet the requirements of large amounts of data and high-density recording, and cannot flexibly select data acquisition modes

[0004] The existing analog control method has the following disadvantages: the monitoring system is too large, and the ground equipment and vehicle equipment are difficult to promote abroad

The structural grade is too fragile to achieve the strength requirements of the black box structure

The storage capacity is limited and cannot meet the requirements of large amounts of data and high density recording

Inability to flexibly choose data acquisition mode
