Problems solved by technology

Due to the difference in the longitudinal section and traction tonnage of each section of the locomotive in actual use, the operating load of the locomotive is very different, which results in different degrees of loss of the locomotive
Therefore, the unified method of determining various maintenance schedules according to the distance traveled by the locomotives is no longer suitable for the requirements of the Ministry of Railways on vigorously deepening the reform of the locomotive repair system, which not only reduces the reliability of some locomotives, but also causes a large amount of unreasonable expenditure on locomotive maintenance costs.

Embodiment Construction

[0035] Embodiments of the invention will be described in detail below with reference to the accompanying drawings.

[0036] This diesel locomotive load recorder is divided into four parts: detection motherboard, sensor, dumper, and management software. They work like this: the sensor collects the current and voltage signals of the locomotive, and after isolation processing, it outputs a stable low-voltage signal and sends it to the motherboard. Receive the locomotive information from the TAX2 box every 50ms, and refresh the main board to record the information coordinates. When data dumping is required, the mainboard record data can be dumped by the dumper and transmitted to the ground computer. The software consists of host detection software, dumper communication software, and ground computer management and analysis software. (See figure 1 )

[0037] The digital signal acquisition and processing of this system is composed of chips U3, U5A, U6, U8 and resistors R6, R8 to ...

Abstract

A load recorder for IC locomotive is composed of the supervisory motherbord inserted in the extension slot of locomotive safety monitor, dumpling device and sensor. The said supervisory motherboard consists of digital signal acquiring-processing circuit, communication circuit, data memory, current-voltage acquiring sensors and controller. It can improve the reliability of locomotive.

Description

technical field [0001] The invention relates to a real-time monitoring instrument for the technical state of a new type of locomotive diesel engine which can monitor the rectified output voltage, current and electric power of the main generator of an electric drive diesel locomotive in real time, thereby calculating the cumulative output power (load) of the locomotive diesel engine in a given period. [0002] It is installed on the expansion slot of the "TAX2 locomotive safety information comprehensive monitoring device" developed and produced by the Zhuzhou Electric Locomotive Research Institute of the Ministry of Railways. Background technique [0003] For a long time, the locomotive maintenance system has always determined the locomotive maintenance cycle and maintenance scope according to a single kilometer. Due to the difference in line longitudinal section and traction tonnage of each section of the locomotive in actual use, the operating load of the locomotive is very...
