Microprocessor device for continuous monitoring and visualization of ambient air temperature by locomotive crews workers

Abstract

The article considers the issue of creating a locomotive microprocessor device for continuous monitoring and visualization of ambient air temperature by members of locomotive crews in order to improve the safety of train traffic at low temperatures and sharply continental climate, typical for the Eastern polygon of JSC «Russian Railways». The conditions of driving and operating trains in winter conditions differ significantly from summer ones. Low temperatures lead to a decrease in the mobility of hinges, the fragility of metals and the likelihood of freezing of pipelines increases, the requirements for brake testing procedures and speed modes of movement of trains change. Speed restrictions on train traffic are already in effect on a number of sections of railways laid along an artificial structure. The increase in the number of emergency situations leads to the need to introduce additional speed limits on a number of sections with a complex path profile. The absence of on-board devices for continuous monitoring and visualization of ambient air temperature with one-time control of train speed has led to the need to search for technical solutions in this direction. Based on the conducted research and taking into account the analysis of the advantages and disadvantages of existing technical solutions, the authors proposed a microprocessor device designed to measure the current ambient temperature, coordinate and speed of the train with the possibility of recording all measured values on a memory card. The conducted field tests have shown the high efficiency of the developed device, as well as its reliability and ease of operation. The relevance of the development and high technical characteristics are confirmed by expert opinions and implementation acts.
