The transportation industry belonging to the tertiary industry in the national economy has reached the cutting-edge technical level in China. The development of China's transportation in these years is mainly reflected in the railway. Railway is the main lifeline of China's transportation and an important direction for China's transportation development. The speed of the trains has made people pay more and more attention to the safety of travel. The edge of the fire wheel is smooth but the rim of the train is always an irregular shape. In this aspect, a very important instrument is the sensor. With the sensor, the safety of the train can be improved step by step.
The geometric state parameters of the fire wheel edge affect the speed and smoothness of the train operation, which is very important for the safe operation of the train。 The traditional detection method is more complicated, usually using a special ruler with a cursor to measure, the measurement error of the manual reading of the data is relatively large, and the digital management of the detection data cannot be realized。 With the development of China's railway industry, trains run faster and faster, and accurate and rapid maintenance and digital management of train rim state parameters become very important。 The rim detector adopts modern sensor technology, single-chip processing system and simple and stable mechanical structure, which can conveniently and accurately measure the geometric state parameters continuously and continuously, and realize the digitization of parameter measurement such as rim height, width and rim thickness。 The detection of rim height, width, rim thickness and so on uses many sensors, and the most concerned is the displacement sensor。 There are many kinds of displacement sensors。 The wheel edge detection used in trains is a new type of sensor technology called laser displacement sensor。 The displacement sensor can accurately measure the position and displacement of the measured object, and is mainly used to measure the geometrical quantities such as displacement, thickness, vibration, distance and diameter of the detected object。
Currently used for laser triangulation on the rim of trains, the measurement accuracy of short distance is very high。 The displacement sensor can be directly mounted on the track for detection。 The laser reflection type displacement sensor can also be used to scan the rim shape of the laser sensor module in the linear direction while recording the entire rim data。 The entire rim contour curve can be obtained by the microprocessor, and the rim width, the rim height, the 70 mm wear amount and the wear area are obtained。 And can upload the measured data to the computer, generate a database, and use the advanced post-processing software to digitally manage the train rim。
It not only can wear the train measuring wheel pair on-line, but also can sort the wheel pair size on the production line. The development of transportation is inseparable from the detection technology, and instrumentation and sensor technology are the core of detection technology. Today, with the development of high-speed power, people not only want to experience the comfort and enjoyment, but also the hope of getting more safety. The development of sensor technology will bring more safety to people's living and transportation. The development of China's sensor technology will also drive the development of first-class advanced technology in the international transportation industry.
