Train axle temperature detection and communication design based on wireless sensor

The failure rate of the device will also increase under high temperature conditions, which will bring more severe challenges to the reliability of the chip. In this paper, the research will be carried out from the characteristics of the chip's elevated temperature and the characteristics of the application, and then an online temperature monitoring system is set up in the subway car in combination with communication technology and sensor network technology. In this paper, the main part of the node detection of temperature and the receiving and sending of files are studied. The temperature of the axle needs to be measured, and then the temperature data is sent to the main part. The node should have the characteristics of easy installation and the main power supply method is battery power. The energy consumption of the collection process should be as low as possible. If temperature collection is not required, the node can maintain low power operation and resume when needed. The structure detection mainly includes the detection module that only receives, and the temperature value module processed by the single-chip microcomputer. The traditional shaft temperature detection efficiency is low, and it is often detected after the fault occurs, which greatly reduces the safety. Therefore, the new shaft temperature detection mode should be combined with the communication technology to enhance the ability of information transmission. New electronic instruments can combine the modular software and hardware into one to test the program. The traditional measurement method is modularized, and finally, a program can be used to complete the specific link of each module, and all the functions can be gathered together to facilitate the realization of the role of the measuring instrument. Together, it can be configured according to a variety of needs, and then the need. The combined modules are connected through the platform and interface to form a test and measurement platform that is more targeted and can be used repeatedly.
