Many large diesel engines are used in the most diverse fields of activities, such as: Railways, ships, oil platforms, mining and agriculture. Many of these engines that are active in Brazil are old and do not have embedded telemetry technology. This study demonstrates the design, development and implementation of a bearing temperature measurement system for a railway diesel engine. A transducer with twenty-four digital sensors was developed, as well as a system for the acquisition and analysis of these data. The entire system has been designed to suit use on locomotives. A system in operation was installed and analyzed and the results showed that the instrumentation techniques used allow monitoring, in a precise way, the temperature of the bearings of an old diesel engine, without affecting its operation. Due to the characteristics of the developed system, it is possible to obtain a large volume of engine temperature data and, from this collected information, perform analysis of wear and engine malfunctions in real time. In addition to the data acquisition system, the system has a supervisory module that generates alarms in case of engine failure identification. In addition, the system also assists in planning preventive and predictive maintenance, reducing downtime. This work was based on an existing system, based on a FBG sensor. It was possible to observe that the two measurement systems (optical and electronic) have similar results, and that the system provided here meets the application. |
